Description

Fixation device for internal jugular central venous catheter for hemodialysis

technical field

The present invention relates to an internal jugular central venous catheter for hemodialysis.

Background technique

In recent years, the prevalence of end-stage renal disease has been on the rise. Most of the patients need blood purification treatment, and the internal jugular central venous catheter is the most widely used temporary hemodialysis access in clinical practice, saving countless patients. patient's life.

The existing fixing method of the central venous dialysis catheter is shown in Figure 1. After the main catheter body 1 is inserted into the patient's internal jugular vein, the suture wing 2 on the main catheter body 1 is sutured to the skin of the patient's neck with sutures, forming a fixation in sequence. But there are shortcomings and deficiencies in this fixing method.

First of all, the internal jugular central venous catheter is fixed with sutures on the suture wings. This fixing method cannot firmly fix the central venous catheter on the patient's neck. Local dressing changes, connection of dialysis tubing, stretching during dialysis, and the elasticity of the patient’s own skin all cause the position of the central venous catheter to move in the internal jugular vein, resulting in the continuous expansion of the skin wound where the catheter enters the neck. Larger scars will be produced after catheterization, and it is also an important reason for blood-borne infection of central venous catheters.

Secondly, due to the fixed suture of the suture wing, it is difficult to thoroughly disinfect the skin from the suture wing to the skin entrance of the central venous catheter and the skin side of the central venous catheter when changing dressings. Blood and exudate accumulate locally, providing opportunities for microbial growth.

Furthermore, after the suture is fixed for a period of time, the suture will fall off from the tissue, so there is a risk that the central venous catheter will fall off, causing bleeding in the patient, and even endangering the life of the patient. Infection is caused by sending the catheter back into the vein. Medical staff often find that the sutures fall off during regular dressing changes, and repeat sutures due to the need for continued dialysis. Due to the multiple sutures and the stimulation of the sutures to the tissue, tissue hyperplasia , After pulling out the central venous tube, many scars were left on the neck, which seriously affected the appearance of the patient's neck.

In addition to the above reasons, the patient was unable to sleep and rest adequately due to the fear of catheter prolapse and bleeding during the catheterization period, which caused great physical pain and mental stress to the patient during the application of the temporary central venous catheter.

Contents of the invention

In order to overcome the problem that the suture wings of the existing internal jugular central venous catheter for hemodialysis are not firmly fixed, and the sutures are easily spit out many times and the sutures fall off, causing the central venous catheter to accidentally protrude, leading to bleeding, infection risks, and multiple sutures. Due to multiple scars on the neck and thus bringing huge psychological pressure to the patient, the present invention provides a fixing device for a central jugular dialysis catheter, which can firmly fix the central venous catheter, avoiding multiple sutures and forming multiple Scars, catheter shedding, and infection, thereby reducing the physical pain and psychological pressure of patients, reducing the risk of medical accidents, and reducing the economic burden on the state and medical insurance.

In order to achieve the above object, the technical scheme adopted in the present invention is:

A fixation device for a jugular central venous catheter for hemodialysis, characterized in that: a neck fixing band is arranged at the intersection of the main catheter body of the internal jugular central venous catheter, the branch catheter at the arterial end, and the branch catheter at the venous end. Both ends of the neck fixing band can be combined and fixed after going around the neck for a week, and a fixing sheet is also provided at the catheter skin entrance between the end of the main catheter body and the neck fixing band.

The fixing device for the internal jugular central venous catheter for hemodialysis, wherein: the two ends of the neck fixing belt are provided with Velcro.

The fixing device for the internal jugular central venous catheter for hemodialysis, wherein: the fixing piece is made of the same material as the main catheter body.

The fixing device for the internal jugular central venous catheter for hemodialysis, wherein: the fixing piece is a circular piece integrally formed with the main catheter body.

The fixing device for the internal jugular central venous catheter for hemodialysis, wherein: the outer diameter of the fixing piece is twice the outer diameter of the main catheter.

The fixing device for the internal jugular central venous catheter for hemodialysis, wherein: the neck fixing belt is not stretchable.

Compared with the prior art, the present invention has the beneficial effects that: the internal jugular central venous catheter is fixed on the neck by the fixing plate, preventing the catheter from moving at the entrance, and the fixing belt provided at the Y-shaped intersection of the catheter can fully The entire tube body is fixed on the neck, and then the neck fixing belt and the fixing sheet are combined to play the role of fixing the internal jugular central venous catheter, which can avoid the body injury caused by repeated sutures due to the suture falling off. Pain and psychological pressure can also avoid the accidental shedding of the catheter, bleeding, infection, and the continuous expansion of the wound at the skin entrance of the catheter caused by the loose fixation of the catheter and tissue hyperplasia.

detailed description

As shown in Figure 2, it is the fixation device of the internal jugular central venous catheter for hemodialysis provided by the present invention, and the suturing wing on the existing internal jugular central venous catheter is replaced by a neck fixing belt 3, and the neck fixing belt 3. It is fixed at the intersection of the main catheter body 1 of the internal jugular central venous catheter, the branch catheter A at the arterial end, and the branch catheter V at the venous end. Adhesive Velcro, according to the different ranges of the depth of the catheter in the human body, a fixing sheet 4 is also provided at the catheter skin entrance at different positions between the end of the main catheter body 1 and the neck fixing belt 3, the The fixed piece 4 is a circular piece integrally formed with the main catheter body 1 with the same material as the main catheter body 1 , and its outer diameter is twice the outer diameter of the main catheter body 1 .

When in use, after the catheter insertion position is determined in the patient's neck, the guide wire is implanted with the guide needle, expanded with the expansion sheath, and a small incision is made with a blade at the entrance of the catheter in the patient's neck along the direction of the guide wire. The main catheter body 1 of the internal jugular central venous catheter is inserted into the internal jugular vein along the guide wire, and when it reaches the fixed piece 4 and contacts the neck, the fixed piece 4 is sent into the subcutaneous tissue of the patient through the incision, and then the The skin incision is sutured, and the neck fixing belt 3 is wound around the back of the patient's neck for adhesion and fixation. At this time, the entire tube body of the internal jugular central venous catheter is fixed on the patient's neck by the combined force of the fixing piece 4 and the neck fixing belt 3 . The sutures can be removed after the skin incision is healed. When pulling out the internal jugular central venous catheter, open the neck fixing band 3, make a small incision at the fixed piece 4 through local anesthesia, then pull out the fixed piece 4 and the internal jugular central venous catheter together.

The above description is only illustrative of the present invention, rather than restrictive. Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope of the application, but All will fall within the protection scope of the present invention.
