TECHNICAL AREA
The present invention relates to a suction electrode, in particular for use in an EKG device (EKG = electrode cardiogram).
STATE OF THE ART
[0002] Sucking electrodes are used in biomedicine, for example to create an EKG (electrocardiogram) or to create an EEG (electroencephalogram). Thanks to a weak negative pressure applied, they have improved skin contact and thus guarantee more optimal measurements. Such suction electrodes are well known in the prior art. For reasons of hygiene, but also for quality assurance of the measurement, it is advantageous if electrodes are replaced after a single use. However, suction electrodes are relatively expensive to manufacture. It is therefore known to divide the suction electrode into a reusable base part and a disposable electrode body.
[0003] Such a suction electrode is disclosed, for example EP 0 143 761 B1. This suction electrode has an electrode plate, a suction head and a connection part with a suction connection. The electrode plate and the suction head form the disposable part, which is disposed of after first use. The connection part forms the base part. The electrode plate has a head which is inserted into the connector through the suction head and thus holds the suction electrode together. Suction channels lead from the connector through the suction head to the electrode. The suction head has a circumferential outer and a circumferential inner sealing lip. The outer sealing lip seals a skin surface of the patient surrounding the electrode from the outside. The inner sealing lip presses sealingly onto the electrode plate from above. During use, the middle area of the suction electrode and thus the electrode plate is pressed towards the skin. As a result, the inner sealing lip bends radially outwards and is raised so that a suction channel is opened between the interior of the intermediate part and the connection part.
EP 0 626 820 B1, EP 0 729 316 B1, EP 0 744 911 B1 and EP 3 011 900 A1 also describe suction electrodes with a part that is disposable after a single use and a reusable part. In these embodiments, the disposable part has a dirt absorber. These suction electrodes are relatively complex and correspondingly costly.
DISCLOSURE OF THE INVENTION
It is an object of the invention to provide a suction electrode, in particular for use in EKG devices, which enables optimal adhesion to the skin of a patient and is nevertheless inexpensive to manufacture.
This object is achieved by a suction electrode with the features of claim 1.
[0007] The suction electrode according to the invention has a base part and an electrode body. The electrode body can be connected to the base part in a detachable and airtight manner. The electrode body has an electrode and a suction head, the electrode comprising an electrode plate. The suction head has an interior space in which the electrode plate is located. The suction head has a circumferential outer sealing lip for resting on a patient's skin and a circumferential inner sealing lip which rests sealingly on a circumferential lateral surface of the electrode plate or on a circumferential lateral surface of a ring surrounding the electrode plate in an airtight manner. The inner sealing lip releases the lateral surface at least partially by means of axial pressure on the base part, preferably completely free, in order to create a suction connection between an interior of the suction head and the base part.
The suction head, also called suction dome, can be designed in a simple form thanks to the inner sealing lip lying on the side. This reduces the manufacturing cost. The lateral contact of the inner sealing lip optimizes the functionality of this seal, which acts as a valve. The valve can open in a circle and thus prevents the suction electrode from shifting on the patient's skin.
In preferred embodiments, the electrode has an electrode head which penetrates the suction head. The base part has an electrode holder for detachably holding the electrode head for the purpose of connecting the electrode body to the base part. As a result, the electrode itself ensures the connection between the electrode body and the base part. This reduces the number of components required and thus the manufacturing costs.
The electrode body preferably has an annular sealing surface directed towards the base part and the base part has a counter-sealing surface directed towards the electrode body. The sealing surface and the mating sealing surface jointly seal the connection between the base part and the electrode body to the outside. The sealing surface and the counter-sealing surface can be designed to be flat. This makes production easier and reduces costs.
The suction head preferably has a central recess which is surrounded by the inner sealing lip, with a receiving opening, preferably a through opening, for the electrode head being present on a bottom. There are suction openings in a circumferential side wall of the recess. This is also a relatively simple and uncomplicated design, which thus facilitates manufacture.
If the annular sealing surface is arranged in the central recess and it surrounds the suction openings, an optimal seal is created in a simple manner. It is also advantageous that the annular sealing surface must have a relatively small diameter. Only the receiving opening for the electrode head and the suction openings need to be located inside the sealing ring. Thanks to the small size, the sealing effect is increased and the risk that the connection between the base part and the electrode body should not be tight is minimized. This idea is claimed as a separate invention, detached from the design of the two sealing lips of the suction head, in particular in relation to the electrode.
[0013] The suction head is preferably at least partially, preferably entirely flexible. It is preferably made of silicone. In preferred embodiments it is formed in one piece.
[0014] In preferred embodiments, the suction head has an essentially circular cylindrical base body. Preferably, no sealing lips or other parts protrude beyond the jacket of the base body. Also on the surface there are preferably only the mentioned depression and optionally a spacer ring surrounding the depression and protruding toward the base part.
The outer sealing lip preferably forms a circumferential inner surface which runs parallel to a central longitudinal axis of the suction electrode. It preferably tapers towards the free end. This training ensures a tight fit on the skin of a patient.
The inner sealing lip is preferably designed to run obliquely towards a longitudinal center axis of the suction electrode towards its free end. It can thus lie tightly against the side surface under prestress.
In preferred embodiments, the base part has a rigid insert part with a suction connection for connection to an external suction source, with a central suction chamber and with suction channels. The suction channels lead from an outer side of the insert part facing the electrode body to the suction chamber and the suction connection leads into the suction chamber. This enables a compact design of the base part. The insert part is preferably made rigid and preferably made of plastic. It can be manufactured at a low cost.
[0018] The insert part is preferably designed to be open on a side opposite the electrode body. The suction electrode has a cover which closes the insert part airtight except for the suction connection and the vacuum channels. Thanks to the open design, a connection between a signal cable connection and an electrically conductive connection element to the electrode head can be established relatively quickly and with simple means during the manufacture of the suction electrode. Access for a soldering point is also given, provided that the connection is made by soldering at all. In addition, the cover can also be designed in different colors in order to create a distinguishing feature. The remaining parts of the suction electrodes can be designed in the same way for different areas to be used. Since larger numbers of the basic components can thus be manufactured, the manufacturing costs are also minimized here.
The shell can be easily attached to the insert if it is flexible. The insert part preferably has an essentially circular cylindrical base body with a circumferential flange protruding radially outward. The casing has an essentially circular cylindrical base body with a circumferential sealing groove directed radially inward, the sealing groove sealingly surrounding the flange. The shell therefore only has to be slipped over the insert in order to complete the base part and to sufficiently seal the interior. This idea is claimed as a separate invention, detached from the design of the two sealing lips of the suction head, in particular in relation to the electrode.
In preferred embodiments, the base part has an electrode holder made of an electrically conductive material. This electrode holder is designed as a separate component and has a dome directed into the base part for contacting a signal cable. Thus, preferably only the electrode holder and the electrode itself are made from an electrically conductive material, in particular from metal. In other embodiments, the electrode holder and the electrode are mostly formed from a non-conductive material and provided with electrically conductive properties by means of coating, doping or other means. The remaining parts are preferably inexpensive, rigid plastic parts or flexible silicone bodies. The minimization of the metal content increases the measurement accuracy and lowers the manufacturing costs.
The inventive electrode body of a suction electrode according to the invention described above has at least the suction head and the electrode. In the first preferred embodiments, this disposable electrode body, which is intended for single use, consists only of these two parts.
In a second embodiment, the electrode body also has a ring which bridges a distance between the electrode plate of the electrode and the inner sealing lip so that the inner sealing lip rests sealingly on the outer surface of this ring. The ring preferably has a circumferential inner support edge for sealing support of the electrode plate. This allows the area of the electrode plate to be minimized. This also minimizes the metal content and lowers costs. The ring can be made from an inexpensive plastic, for example. It is preferably made rigid. In preferred embodiments, the suction electrode consists exclusively of these three components.
[0023] Further embodiments are given in the dependent claims

DESCRIPTION OF PREFERRED EMBODIMENTS
In Figures 1 to 12, a first embodiment of the suction electrode according to the invention is shown. It can be used in particular for EKG, preferably also for EEG or for other biomedical measurements.
The suction electrode has a base part A and an electrode body B. The electrode body B can be detachably plugged into the base part A for the use of the suction electrode. The electrode body B is designed as a disposable part and is preferably disposed of after it has been used for the first time. The base part A is intended and designed for multiple use.
The base part A can be connected to a vacuum pump of a known type. For this purpose it has an electrode tube 6. The hose 6 is preferably firmly connected to the rest of the base part A. In other embodiments, it can be releasably attached to the rest of the base part A.
The suction hose 6 has a jacket 60 which merges in one piece into a sleeve 600 at one end. The sleeve 600 can be slipped over a connection piece 21 of the base part A or, depending on the diameter ratio, pushed into it.
The suction hose 6 has a suction lumen 62 for applying a negative pressure inside the base part A. A signal cable 61 runs in the suction lumen 62 for transmitting the measurement signals to an evaluation unit (not shown), for example an EKG device. An end piece 610 of the signal cable 61 is bent in this example. This can be clearly seen in FIGS. 3 to 5. However, it can also be designed in other known ways.
In FIGS. 3 to 5, the further components of the suction electrode according to the invention are also shown in an exploded view. The base part A here comprises a cover 1, an insert 2 and an electrode holder 3. The cover 1 is preferably made of a soft, in particular a flexible material. For example, it is made of silicone. The insert 2 is rigid. It is preferably made of plastic. The electrode holder 3 is made of an electrically conductive material, in particular metal. These three components are preferably each formed in one piece.
In this example, the electrode body B consists of a suction head 4 and an electrode 5. The suction head 4 is preferably made of a soft, in particular an elastic, material. It is preferably made of silicone. The electrode 5 is made of an electrically conductive material, preferably metal. Alternatively, it is designed to be electrically conductive at least on its surface, for example by means of a coating. The electrode holder 3 can only be provided with a corresponding conductive coating. The suction head 4 and the electrode 5 are preferably designed in one piece for themselves.
In the figures 8 to 12, the individual components of the suction electrode according to the invention are shown individually.
FIG. 8 shows the electrode 5. In this example it is designed as a so-called stamp electrode. It has a base body in the form of an electrode plate 50 with a flat surface 51. The planar surface 51 can be clearly seen in FIG. An electrode head 52 is formed on the electrode plate 50.
Figures 9a and 9b show the suction head 4. It has a cylindrical base body 40 which is designed to be open on one side and ends in a circumferential outer sealing lip 41. The opposite side of the base body 40 is designed to be closed apart from a central receiving opening 43 and suction openings 45. The central receiving opening 43 and the suction openings 45 are located in a central dome-shaped recess 44, also called a trough. The recess 44 has a step 46 on its upper edge which forms a horizontally running sealing surface 47. A raised, closed spacer ring 48 adjoins the recess 44 when viewed radially outward. The suction openings 45 are present in the inclined area of the recess 44. There are four openings 45 here. Their diameter is preferably many times smaller than the diameter of the receiving opening 43.
The base body 40 of the suction head 4 defines an interior space 49. A circumferential inner sealing lip 42 projects into this interior space 49. It preferably directly adjoins the dome-shaped recess 44. The inner sealing lip 42 preferably ends with its free end at the same height as the lowermost outer side of the recess 44 protruding into the interior. The receiving opening 43 is preferably located at this point.
The inner sealing lip 42 preferably tapers towards its free end. In addition, it is preferably inclined towards the longitudinal center axis L of the suction electrode.
The outer sealing lip 41 also preferably tapers towards its free end. It extends with its inside preferably parallel to the longitudinal center axis L of the suction electrode and is therefore not inclined. The tapering takes place preferably via the outer side wall. The outer sealing lip 41 projects beyond the inner sealing lip 42 in the longitudinal direction L of the suction electrode, preferably by at least half the height of the suction head 4.
The electrode holder 3 is shown in FIG. 10 and can also be seen clearly in FIGS. 3 to 5. The electrode receptacle 3 has a base 30 with a receptacle opening 32 and a dome 31. In contrast to the receiving opening 43 of the suction head 4, the receiving opening 32 is not continuous, but is preferably designed as a blind hole. At least one retaining element 33, for example a clip or a spring part, is preferably arranged in the receiving opening 43. Two such retaining elements 33 are preferably provided diagonally to one another. FIGS. 11a to 11c show the insert 2. It has a cylindrical base body 20 which is designed to be closed on one end face except for a central receiving opening 25 and openings for suction channels 23, 24. The closed end face of the insert part 2 is surrounded by a flange 22 protruding radially outward. The receiving opening 25 is surrounded by a circumferential step 26 which forms a counter-sealing surface 27. The counter-sealing surface 27 can be seen in FIGS. 3 and 11b, the step 26 in FIGS. 3 and 4.
The opposite end face of the base body 20 is designed to be open. The interior of the base body 20 is reinforced by means of webs 29. They enclose a suction chamber 28 which opens into the receiving opening 25. The first suction channels 23 open into the suction chamber 28.
The connecting piece 21, which creates a connection from the suction hose 6 to the suction chamber 28, is molded onto the jacket of the base body 20. The second suction channel 24 is arranged in the area of this connecting piece 21. It is shorter than the two first suction channels 23 and thus enables the connection between the suction connection 21 and the suction chamber 28. Thanks to this design, the area that has to be subjected to a vacuum within the base part A is minimized.
Sheath 1 is shown in FIG. 12. It has a jacket 10 with a through opening 11. The casing 1 is designed to be open on one end face and has a receiving opening 13. The jacket ends on this free side in an inwardly projecting sealing groove 16. The opposite end is designed to be closed. The shell 1 thus has the shape of a cap with an interior 12. The closed end face preferably has a recess 14 into which a marking 15 in the form of a round, flat plate can be inserted. The plate can for example have a lettering and / or color coding.
In FIGS. 6 and 7, the suction electrode is shown in the assembled state. In the illustration according to FIG. 6, the suction electrode is shown in the resting state, in FIG. 7 during use.
As can be seen in FIG. 6, the electrode head 52 penetrates the receiving opening 43 of the suction head 4. It is held in the receiving opening 32 of the electrode receptacle 3 in a detachable, preferably clamping manner. The tip 31 of the electrode holder 3 is contacted by an end piece 610 of the signal cable 61. The end 610 can also be soldered onto the dome 31. The cover 1 is pushed onto the insert part 2. The sealing groove 16 of the shell 1 engages around the flange 22 of the insert part 2 and thus seals the insert part 2 from the outside in airtight manner.
The step 26 with the mating sealing surface 27 of the insert part 2 forms, together with the step 46 and the sealing surface 47 of the suction head, a further circumferential seal. The suction channels 23, 24 of the insert 2 end within this sealing ring and the suction openings 45 of the suction head 4 are also located. The connection between the suction channels 23, 24 and the suction openings 45 is thus also closed airtight from the outside.
As can also be seen in Figure 6, the inner sealing lip 42 is sealingly on the side surface of the electrode plate 50, i. on the jacket of the electrode plate. As a result, the connection between the interior space 49 of the suction head 4 and the suction openings 45 is interrupted. The valve, formed by the inner sealing lip 42 and the outer surface of the electrode plate, is closed.
During use, a vacuum is applied to the suction chamber 28 of the insert part 2 by means of a vacuum pump (not shown) via the electrode hose 6. The suction electrode is then lightly pressed onto the patient's skin by the user pressing on the cover 1. The outer sealing lips 41 seal the covered skin area from the outside. This axial contact pressure on the electrode 5 presses the electrode 5 onto the patient's skin. In addition, the dome-shaped recess 44 of the suction head 4 is also moved axially downwards. The inner sealing lip 42 is bent slightly outwards and thus gives the valve seat, i.e. the outer surface of the electrode plate 50, free. The passage between the interior space 49 of the suction head 4 and the suction openings 45 is released. The negative pressure that previously only prevailed in the suction chamber 28 of the insert part 2 is now also applied in the interior 49 of the suction head 4. The valve remains open. The user can now set the negative pressure on the vacuum pump in such a way that the suction electrode is held in its position, but the suction is still comfortable for the patient and in particular does not produce any hematomas or painful marks on the skin.
The suction electrode can be removed from the skin, for example after use, by either manually grasping it in the area of the outer sealing lip 41 of the suction head 4 or by actuating a blow-out function of the vacuum pump. In the latter case, the suction electrode falls off by itself.
A second exemplary embodiment is shown in FIGS. 13 and 14. The suction electrode basically has the same structure and parts as the suction electrode according to FIGS. 1 to 12. The same parts are therefore given the same reference numerals. Missing reference symbols can be assigned in a simple manner by comparing the figures. The electrode 5 is, however, made smaller in this example. The electrode plate 50 has a smaller diameter, so that the inner sealing lip 42 ends at a distance from it. The distance is bridged by means of a ring 7. The ring 7 has in its inner opening a flange 70 protruding radially inward in order to rest on the electrode plate 50 of the electrode 5 and to be carried by the latter. On the other hand, the ring 7 has an outer jacket with a side surface against which the inner sealing lip 42 rests in a sealing manner and protrudes when the negative pressure is applied.
The suction electrode according to the invention has a disposable part, can be manufactured inexpensively and is nevertheless of high quality in use.
