    Catheter and catheter applicator incorporating said applicator OBJECT OF THE INVENTION
    The present invention relates generally to auxiliary catheterization instruments for insertion of a catheter into a blood vessel.
    More specifically, the invention relates to a catheter applicator device for insertion of a catheter into a blood vessel, which aims to minimize the risks of infection by phlebitis or bacteremia associated with catheter infection, especially in catheters. peripheral veins.
    The invention also relates to a catheter that integrates said applicator device. BACKGROUND OF THE INVENTION
    The recommendations on insertion of a catheter are universally applicable regardless of the nursing or medical staff that inserts the catheter and regardless of where the procedure is performed. Currently, with the existing catheterization instruments, it is necessary for the healthcare personnel to touch the proximal catheter with their fingers at the time of insertion technique, thus being able to contaminate the catheter's body.
    Catheter-associated bacteraemia is one of the most frequent causes of infection acquired in the hospital setting. The incidence of bacteremia associated with catheter per 1000 days of admission ranges between 0.30 and 0.50 according to various published series. A non-negligible number of these bacteremia are related to venous catheters inserted in peripheral veins.
    Auxiliary peripheral venous catheter channeling devices are known in the state of the art, intended for the protection of health personnel, and others that help optimize the procedure by means of catheter fixation and stabilization systems on the patient.

    However, no system specially designed to reduce the incidence of bacteraemia and infections associated with peripheral catheters is known.
    DESCRIPTION OF THE INVENTION
    The present invention solves the previously mentioned shortcomings of the state of the art, providing an applicator for catheters that allows the catheter insertion technique to be carried out in a patient, without it being necessary for the fingers of the healthcare staff to contact at any time with the catheter.
    For this, a first aspect of the invention relates to a catheter applicator comprising two parts, a part intended to be fixed or fixedly attached to the base of a generic catheter, and a second part with a suitable shape to be held by the fingers of a user as nurses or doctor. These two parts are joined together by a removable joint, preferably sized to be breakable or fractured by manual action, either by twisting, bending and / or traction between the two parts of the applicator.
    Thus, to insert a catheter into a blood vessel, the user holds with his fingers the applicator by the hand-grip part, and attaches it to the proximal part (or base) of a conventional catheter by means of the fixation part, by for example, by means of a pressure coupling, both parts being stably fixed, and without it being necessary to touch the catheter at any time.
    Once the applicator is attached to the catheter, it is inserted into a blood vessel holding the assembly only by the grip part, for which the joint area is sized to perform the insertion keeping the assembly stable.
    After the correct insertion of the catheter and its connection to a plug, a needleless connector or an infusion system, the user proceeds to remove the grip part manually by breaking the joint area, simply by flexing, twisting or pulling the part of grip with respect to the fixing part, until the material in the joining area ruptures. The fixation part remains attached to the base of the catheter, without this causing discomfort to the patient or inconvenience in the subsequent use of the same.
    Preferably, these two parts are joined together by a dimensioned joint

    so that it is breakable or fractured by manual action, either by torsion, flexion and / or traction between the two parts of the applicator.
    However, the area of union between the fixing part and the manual gripping part can be implemented in any other way that allows easy separation between both parts manually.
    Another aspect of the invention relates to a catheter conventionally provided with a catheter base and a needle inserted by one of its ends in said base. The catheter of the invention is characterized in that it also comprises an applicator element that includes a hand grip part suitable for being held by the fingers of a user, which is joined by a removable joint with the base of the catheter, where preferably said joint is breakable or fractured by manual action.
    DESCRIPTION OF THE DRAWINGS
    To complement the description that is being made and in order to help a better understanding of the features of the invention, according to a preferred example of practical realization thereof, a set of drawings is accompanied as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:
    Figure 1 shows a perspective view of an embodiment of an applicator device according to the invention.
    Figure 2 shows a perspective view of the device of Figure 1 coupled to a conventional catheter for insertion into a blood vessel.
    Figure 3.- shows another preferred embodiment of the invention, in which the catheter and the applicator form the same device.
    PREFERRED EMBODIMENT OF THE INVENTION
    Figure 1 shows an embodiment of an applicator for catheters according to the invention, comprising a fixing part (1) configured to be fixedly coupled to the base (4) of a catheter (7), and a grip part appropriate manual (6), that is,

    configured to be held by a user's fingers. The fixing part (1) and the manual gripping part (6) are joined together by a breakable joint (9) by manual action.
    Preferably, the catheter applicator consists of a single piece, made of plastic material in an injection molding process, and so that the breakable joint (9) consists of a narrowing of the piece, such that it can be broken by a simple action manual, flexing or turning the grip part (6) with respect to the fixing part (1).
    The fixing part (1) is in the form of a cylindrical bushing with an opening, so that it forms two curved eyelashes, which by way of a clamp and by the elasticity of the plastic material with which they are made, can be coupled by elastic deformation on the base (4) of a catheter (7), being fixed thereto under pressure and in a stable manner. For this, the internal diameter of said cylindrical bushing is substantially coincident with the external diameter of the base (4).
    In addition, the fixing part (1) has an extension (5) at one of its edges, which serves as a stop and to improve the coupling with the base (4) of the catheter.
    On the other hand, the manual gripping part (6) is formed in this preferred embodiment by a wall (2) and a support surface (3) that is attached to one end of the wall (2). In turn, another end of said wall (2) is connected to the fixing part (1) by the breakable joint (9). The support surface (3) is "ergonomically" designed to have the shape of the finger pulp.
    As can be seen in the figures, the breakable joint (9) is arranged on the outer surface of the fixing part (1), so that when the gripping part (6) is removed there is no projection or living part left. may bother the patient.
    Figure 2 shows the applicator of Figure 1 coupled to a conventional catheter (7), comprising a catheter base (4) of plastic material and a needle (8) inserted by one of its ends in said base (4).
    The fixing part (1) is designed to be applicable to catheters of different manufacturers.
    Figure 3 illustrates another preferred embodiment of the invention, in which the applicator is integrated in a catheter (7), so that the assembly forms a single device. In this case, the breakable joint (9) is formed between the applicator and the base (4) of the catheter. The applicator has a manual gripping part (6) as described above in relation to the figure (1) provided with a support surface (3) attached to a wall (2) in turn attached to the base (4 ) of the catheter.
    The base (4) of the catheter and the applicator are preferably obtained as a single piece of plastic material suitable for sanitary use, which is dispensed under sterile conditions.
    It can be seen in view of the figures, that the invention allows in a simple and economical way, to perform a venipuncture technique avoiding at all times the manipulation of the proximal area of the catheter and without the need for sterile gloves.
