    State of the art
    The invention relates to a device for removing a foreign body, in particular a tick.
    Known devices for removing a foreign body, in particular a tick, in this case are designed as tick tongs.
    The object of the invention is in particular to provide a device which allows a simple and infection-inhibiting removal of foreign bodies, especially ticks or insects, from the skin. The object is achieved by the features of claim 1, while advantageous embodiments and modifications of the invention can be taken from the dependent claims.
    Advantages of the invention
    It is proposed a device which is provided for removing at least one foreign body, in particular a tick or an insect, from the skin, wherein the device has a negative pressure unit which is provided to generate a negative pressure in the region of the foreign body, and wherein the device comprises a manipulator unit which is provided to exert at least one tensile force on the at least one foreign body. Under a "manipulator" should be understood in this context, in particular at least one unit that is actu bar by an operator outside the vacuum unit and can perform a three-dimensional movement and rotation about its own axis within the vacuum unit to exert a force on the foreign body , In particular, the manipulator unit may have a gear unit and / or a drive unit. The manipulator unit may comprise a mechanical element which can be operated manually and / or an electrically driven element which can be operated by cable or wireless. In particular, the manipulator unit is infinitely or stepwise movable. At least two units of the manipulator unit can be moved independently of each other. In particular, a first unit of the manipulator unit can be drive-actively coupled to a second unit of the manipulator unit via a gear unit. The manipulator unit may comprise a slide displaceably mounted on a manipulator arm element, which carriage is designed to be linearly movable and / or is drive-coupled to a drive unit. In a further embodiment, it is conceivable that at least a portion of the manipulator unit is magnetically formed and / or movable via a magnet. In particular, the manipulator unit may be provided with a receiving device for receiving the foreign body to be handled and / or a tool suitable for its processing. The manipulator unit may preferably consist of materials and / or combinations of materials, such as metals and / or non-metals, which have an antibacterial effect and / or can be disinfected.
    In an advantageous embodiment of the invention, the vacuum unit on a receiving area, which is intended to hermetically enclose the area around the foreign body. In this context, a "negative pressure" is understood to mean a pressure, in particular an air pressure, which is lower than an ambient pressure, in particular an ambient air pressure. By "intended" is intended to be understood in particular specially designed, designed and / or equipped. An essential task of the negative pressure which can be generated by means of the vacuum unit is to prevent transmission of infectious and / or allergenic body fluids or secretions, in particular of a tick, into the skin of an individual or a patient to be treated and thus to minimize a risk of infection. By means of the device according to the invention, a foreign body, in particular a tick, can be removed gently and / or from the skin of an individual or a patient by means of a vacuum unit under a permanently acting negative pressure, without removing the foreign body, in particular the tick , Remove microbes from the skin and / or from the skin in the tick enter the skin of the individual or the patient.
    It is also proposed that the vacuum unit has a bearing unit which is designed for mounting the manipulator unit. In particular, the manipulator unit is movably mounted in the storage unit. The term "movably mounted" should in particular define a mounting of the manipulator unit and / or a tool element, wherein the manipulator unit and / or the tool element, in particular decoupled from an elastic deformation of the manipulator unit and / or the tool element, has an unlimited mobility along a path and / or has unrestricted mobility around at least one axis.
    In particular, the bearing unit may have a recess which can accommodate differently designed tool elements of the manipulator unit. In particular, the bearing unit may be formed at least substantially of a rubber-elastic material or of a plastic or of a metallic material. Of course, other materials that appear appropriate to a person skilled in the art and / or a combination of different materials for implementing the bearing unit are also conceivable. "Elastic" should be understood in particular a material property of an element that allows repeated deformation of the element, without thereby the element is mechanically damaged or destroyed, and in particular after a deformation of the element allows an independent striving of the element into an initial shape. In an advantageous manner, this makes it possible to provide a simple and particularly user-friendly storage unit for mounting the manipulator unit.
    Furthermore, it is proposed that the manipulator unit has at least one tool element which is provided for gripping and / or holding the foreign body. In particular, the tool element can be designed as a gripping tool element. In an advantageous manner, the tool element of the manipulator unit can have a one-part or a multi-part design. The tool element can be designed as tweezers, as an endoscopic instrument, as another surgical instrument or as a suction element, although other medical devices considered appropriate by a person skilled in the art within the meaning of Directive 93/42 / EEC are also conceivable. In addition, the manipulator unit can have a receiving unit for receiving further different tool elements, such as, for example, a clamp element or a suction element or a carrier element or the like. This can advantageously be changed to a gentle removal of the foreign body, in particular the tick or insect, from and / or from the skin, in particular the tool element of the manipulator unit in its length, for example by having a telescopic length change device. In a further embodiment, the tool element of the manipulator unit may have a joint which is provided to optimize the position of the tool element to the foreign body and / or to set a best possible leverage ratio when removing the foreign body.
    In a further advantageous embodiment of the invention it is proposed that the manipulator unit has at least two equal or different trained tool elements. As a result, an advantageously good and reliable removal of the foreign body, in particular the tick or the insect, from and / or from the skin of an individual or a patient can be achieved.
    A tool end of the at least one tool element may act in an adjacent to the foreign body and / or arranged around the foreign body processing area. Furthermore, at least two tool ends of the tool elements directed towards the foreign body can overlap in the area of the foreign body in the processing area. In this context, a "processing area" is to be understood as meaning, in particular, a region around the foreign body which is contacted and processed directly by the at least one tool element of the manipulator unit in a processing state. In particular, the tool elements that are in an operative connection with one another can work on the foreign body alternately, individually or simultaneously together and / or detach from the skin or remove it from the skin.
    Further, it is proposed that the vacuum unit comprises at least one bearing unit having at least one sealing element which is intended to hermetically close an inner region of the vacuum unit to an outer area. The sealing element is advantageously designed annular. An annular configuration of the sealing element can particularly simplify handling of the sealing element during assembly, as a result of which cost-intensive assembly time can be saved. Preferably, the sealing element can be made at least partially, preferably substantially completely, particularly preferably in one piece from a flexible and / or an elastic material, such as a rubber-elastic material. By "flexible" is to be understood in particular that at least one element is not rigid or not fixed, but that the element is variable in its contour and / or adjustable and is for example at least partially formed of an elastic material. Alternatively, the sealing element may be at least partially formed of an inelastic material.
    In particular, the sealing element may be formed integrally and / or in one piece with the vacuum unit or be subsequently connected to the vacuum unit. Furthermore, the sealing element can have a sealing lip in an edge area or in a transition area to the vacuum unit, whereby a hermetically sealed transition between the bearing unit and the vacuum unit can be ensured. The sealing element can react to changes in pressure by elastic deformation. In particular, the sealing element can be formed in one piece or in several parts. The term "integral" should be understood in particular to be materially bonded, as for example by a welding process and / or adhesive process, etc., and particularly advantageously formed, such as by the production from a casting and / or by the production in a one- or multi-component injection molding process.
    At least two sealing elements of the vacuum unit can enclose the bearing unit by a sealing element is arranged on an inner wall and a further sealing element is arranged form-fitting manner on an outer wall of the vacuum unit. By "positive fit" is to be understood in particular that abutting surfaces of mutually positively connected components exert a force acting in the normal direction of the surfaces holding force on each other. In particular, the components are in geometric engagement with each other. In particular, the sealing element without additional fastening means on the storage unit and / or on the vacuum unit can be mounted particularly easy to install. In particular, the sealing element may have a concentrically formed recess which is formed in alignment with the recess of the bearing element. By "in-line" is to be understood in particular that a first component starting from a fictitious point and / or a second component in perspective both in terms of an excellent direction, in particular a rotation axis, a direction of movement and / or a main extension direction, as well as in With respect to a spatial positioning with the fictitious point and / or the second component matches.
    In particular, the recess of the sealing element can receive the tool element of the manipulator unit. In particular, the sealing element can be adapted particularly advantageous to different dimensions and designs of the tool element. A significant advantage of the present invention is that due to the sealing element with a permanent pressure, a movable mounting of the manipulator unit and a permanent hermetic seal can be guaranteed. In particular, with the inventive sealing element, the tool element of the manipulator unit can be exchanged while the removal of the foreign body while maintaining the negative pressure. Advantageously, the sealing element in the inventive device simultaneously perform several functions, such as the function of a sealing member and / or the function of a bearing element and / or the function of a separating element.
    It is further proposed that the bearing unit has at least two bearing elements, which are arranged at least substantially diametrically opposite to a base body of the vacuum unit. Advantageously, the diametrically opposed arrangement of the bearing elements allows a maximum possible freedom of movement of tool elements of the manipulator unit and a high sealing effect of the sealing element in the storage unit. In particular, can be additionally inclined and / or moved and fixed by a further, vertically above the foreign body arranged bearing element of the foreign body in a desired position. Due to the inventive design of the storage unit of the device, a foreign body, in particular a tick, of at least two tool elements of the manipulator unit, which are preferably arranged diametrically opposite, simultaneously treated and removed from and / or from the skin of an individual or a patient gently.
    Furthermore, it is proposed that the bearing elements of the bearing unit are formed substantially of an elastic material.

    Description of the embodiments
    1 and 2 each show a device for removing a foreign body 24, in particular a tick or an insect, from the skin 26 of an individual or a patient. The device comprises a vacuum unit 10, which generates a negative pressure in the region of the foreign body 24. The vacuum unit 10 has a base body 22 of transparent design, which consists of a pressure-resistant plastic. The main body 22 of the vacuum unit 10 is spherical and has a circular receiving area 28, which receives the area of the skin 26 with the foreign body 24 and hermetically encloses. To generate the negative pressure, the vacuum unit 10 comprises at least one pump unit 32, which generates a negative pressure in the main body 22 of the vacuum unit 10. The pump unit 32 is connected via a vacuum-resistant air duct element 30 to the main body 22 of the vacuum unit 10.
    A negative pressure has an essential meaning for a successful removal of the foreign body 24 from and / or from the skin 26 of the individual or the patient. As a result of the negative pressure generated in the vacuum unit 10, the skin 26 with the foreign body 24 bulges into the receiving area 28 of the vacuum unit 10, thereby enlarging the skin surface of the skin area under tension. The foreign body 24, in particular the tick, is almost exposed in this phase and no longer sits so deeply in the skin 26 of the individual or the patient. A deep-seated and / or a small tick is thus more tangible. In addition, the negative pressure generated in the vacuum unit 10 permanently acts on the foreign body 24, in particular on the tick, and causes a suction effect on already transmitted infectious and / or allergenic body fluids of the tick even after removal of the tick. In particular, the direction of flow of the body fluid of the tick and the flow direction of the blood of the individual or of the patient in the sense of avoiding infections are favorably influenced. The pressure of the body fluid of the tick essentially corresponds to the pressure in the interior of the vacuum unit 10, since the body of the tick, in particular its distensible abdomen, is not pressure-stable. The blood pressure of the patient corresponds substantially to the pressure of the environment or the atmosphere outside the vacuum unit 10 and is thus higher than the pressure of the body fluid of the tick in the vacuum unit. Therefore, the blood pressure of the patient or the flow direction of the blood of the patient determines the flow direction of the body fluid of the tick, which flows from the patient in the direction of the tick. In particular, the negative pressure generated can reliably prevent microbes or body fluids from entering the skin from the tick, since the negative pressure acting on the body of the tick increases the body surface of the tick, on the pressure-unstable body surface of the tick on her body interior and in particular on their body fluids transmits and effectively inhibits excretion of microbes or body fluids. The tick, which is almost exposed on the skin 26, clings with its forceps in the skin 26 of the individual or the patient and has to be removed manually. In addition, it is possible that the tick is killed solely by the negative pressure and consequently loses its holding power. Furthermore, it is conceivable that the tick can be anesthetized or destroyed by targeted introduction of suitable chemical substances into the vacuum unit 10.
    To remove the foreign body 24, in particular the tick, the inventive device according to FIG. 1, a manipulator 12, by means of which a tensile force on the foreign body 24 is exercisable. The manipulator unit 12 has two tool elements 12.1, 12.2 for gripping and / or holding the foreign body 24 in the tool area 12.1b, 12.2b. In the present exemplary embodiment, the tool elements 12.1, 12.2 are designed as gripper tool elements, in particular as forceps. Furthermore, the manipulator unit 12 has tool elements 12.1, 12.2 of the same length, which cooperate in a processing area adjoining the foreign body 24 and / or arranged around the foreign body 24.
    The tool elements 12.1, 12.2 of the manipulator unit 12 penetrate radially the spherical base body 22 of the vacuum unit 10 and are movably mounted in the base body 22 of the vacuum unit 10. An operating area 12.1a, 12.2a of the tool elements 12.1, 12.2 located outside the main body 22 of the vacuum unit 10 serves to operate the manipulator unit 12 by at least one person. A tool area 12.1b, 12.2b of the tool elements 12.1, 12.2, which is located within the base body 22 of the vacuum unit 10 and faces away from the operating area 12.1a, 12.2a of the tool elements 12.1, 12.2, serves to remove the foreign body 24, in particular the tick or the insect , from and / or from the skin 26 of an individual or a patient. This allows a person with the help of the tool elements 12.1, 12.2 of the manipulator unit 12, the foreign body 24 simultaneously or alternately edit and / or on the skin 26 due to the permanently acting negative pressure almost exposed tick, with their pliers in the skin 26 of the individual or clinging to the patient, manually grasp and remove with two tool elements 12.1, 12.2. Before, during and after the manual removal of the foreign body 24, in particular the tick, from and / or from the skin 26, there is a negative pressure in the vacuum unit 10 in a state arranged on the skin 26. Consequently, after removal of the foreign body 24, in particular the tick, from and / or from the skin 26, the negative pressure acting in the vacuum unit 10 continues to act on the wound in the skin 26 and removes from the wound possibly already infected body fluid from the skin 26. As a result, a risk of infection can be kept low.
    As can be seen from Fig. 1, the vacuum unit 10 has a bearing unit 14, which is designed for mounting the manipulator unit 12, wherein the bearing unit 14 in the present embodiment, two bearing elements 14.1, 14.2. For receiving the bearing elements 14.1, 14.2, the spherical base body 22 of the vacuum unit 10 for each bearing element 14.1, 14.2 a circular recess. The bearing elements 14.1, 14.2 are formed from an elastic material and formed into a coaxial receptacle of the tool elements 12.1, 12.2 of the manipulator unit 12. The integrally formed bearing elements 14.1, 14.2 are configured such that the tool elements 12.1, 12.2 of the manipulator unit 12 are rotatable about their own axis, pivotable at an angle and towards the foreign body 24 and / or away from the foreign body 24. Furthermore, the two bearing elements 14.1, 14.2 of the bearing unit 14 are arranged diametrically opposite to a base body 22 of the vacuum unit 10.
    In addition, the vacuum unit 10 includes the bearing unit 14, which has at least one sealing element 16.1, 16.2, which is intended to hermetically close an inner region 18 of the vacuum unit 10 against an outer region 20. The sealing element 16.1, 16.2 covers in a mounted state, the bearing elements 14.1, 14.2. For receiving the tool element 12.1, 12.2 of the manipulator unit 12, the sealing element 16.1, 16.2 has a coaxially formed recess which extends perpendicular to a longitudinal axis of the tool elements 12.1, 12.2 of the manipulator unit 12. An outer edge of the sealing element 16.1, 16.2 is flush with a surface of the base body 22 of the vacuum unit 10 at. In particular, the positively fastened sealing element 16.1, 16.2 on the longitudinal axis of the tool elements 12.1, 12.2 of the manipulator unit 12 coaxial recess, which is provided for receiving and / or for passing the tool elements 12.1, 12.2 of the manipulator unit 12. In an assembled state, the sealing element 16.1, 16.2 thus lies positively in the recess of the base body 22 and seals the tool elements 12.1, 12.2 of the manipulator unit 12 radially and axially relative to the vacuum unit 10. For the sealing element 16.1, 16.2, a rubber elastic deformable material is used.
    2, a further embodiment of the invention is shown. The following description and the drawings are essentially limited to the differences between the exemplary embodiments, with reference in principle to the drawings and / or the description of the other exemplary embodiment, in particular FIGS. 1 can be referenced. To distinguish the embodiments of the letter c is the reference numerals of the embodiment in Fig. 1 adjusted.
    The negative pressure unit 10c has a hold-down unit 34c which holds down the area of the skin 26c of an individual or a patient adjacent to the foreign body 24c. Thus, the hold-down unit 34c is provided to hold down the portion of the skin 26c of an individual or a patient adjacent to the foreign body 24c. The hold-down unit 34c includes at least one plate member 36c disposed in a receiving portion 28c of the main body 22c in the negative pressure unit 10c.
