Description

Temporary dialysis tube fixation device for hemodialysis patients' neck

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a temporary dialysis tube fixing device for the neck of a hemodialysis patient.

Background technique

Maintenance hemodialysis is the most commonly used renal replacement therapy for patients with end-stage renal disease. Good vascular access is a prerequisite for the smooth progress of hemodialysis. Central venous catheters, as a temporary vascular access, are widely used in emergency dialysis and immature transitional periods of arteriovenous fistulas in patients requiring short-term and long-term dialysis. Usually, there are two temporary dialysis accesses: temporary dialysis tubes in the neck and temporary dialysis tubes in the femoral vein. In this study, a comfortable fixation device was designed for patients with temporary dialysis tubes in the neck to better fix and maintain the pipeline. Comfort refers to a self-feeling when an individual's body and mind are in a healthy and peaceful state of ease, satisfaction, no anxiety, and no pain.

There is currently no unified fixation device and technique for the fixation of temporary dialysis tubing in the neck in clinical practice. Generally, clinical nurses, patients and their families use adhesive tape to stick on the patient's ears or neck according to experience, or use elastic bandages to fix on the side of the head. However, these fixation methods cannot meet the patient's daily activities and comfort needs, and the fixed head end is easy to fall off, which often causes the patient's irritability and frustration. Repeated fixation and falling off are more likely to cause the dressing at the catheter puncture site to fall off, exposing the catheter puncture site, increasing the risk of infection for the patient, aggravating the patient's condition, and intensifying the doctor-patient conflict. Therefore, it is necessary to invent and design a new type of temporary dialysis tubing fixation device for the neck.

Utility Model Content

In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a temporary dialysis tube fixing device for the neck of a hemodialysis patient, which effectively solves the problem that the existing neck dialysis tube is easy to fall off when fixed.

The technical solution is that the utility model includes an arc-shaped elastic plate, a drawstring is provided at the left end of the rear side of the elastic plate, a fixing ring is provided at the left end of the front side of the elastic plate, a fixing block is slidably connected to the front end of the elastic plate, a placement groove which runs through from top to bottom and opens forward is provided on the fixing block, a pressure plate is hinged on the right side of the front end of the fixing block, the middle part of the pressure plate is semicircular, the pressure plate can form a circle with the placement groove, and extrusion airbags are respectively provided on the left and right sides of the fixing ring, which can be inflated.

The utility model has an ingenious structure and is easy to use. It is convenient for medical staff to fix the temporary dialysis tube on the neck. The temporary dialysis tube can be fixed on one side of the patient's head, which is beneficial to the patient's postoperative care. At the same time, a slide rail is provided to facilitate medical staff to adjust the fixed position of the temporary dialysis tube on the neck according to the patient's treatment needs, so as to improve the patient's use effect and comfort, and is beneficial to the operation and use of patients and medical staff. The utility model has a simple structure, is easy to operate, has a novel conception, and is highly practical.

Implementation

The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

As shown in Figures 1 to 5, it includes an arc-shaped elastic plate 1, a drawstring 2 is provided at the left end of the rear side of the elastic plate 1, a fixing ring 3 is provided at the left end of the front side of the elastic plate 1, a fixing block 4 is slidably connected to the front end of the elastic plate 1, a placement groove 5 which passes through from top to bottom and opens forward is provided on the fixing block 4, a pressing plate 6 is hinged on the right side of the front end of the fixing block 4, the middle part of the pressing plate 6 is semicircular, and the pressing plate 6 can form a circle with the placement groove 5, and extrusion airbags 7 are respectively provided on the left and right sides of the fixing ring 3, and the extrusion airbags 7 can be inflated.

In order to facilitate the use of the drawstring 2 and the fixing ring 3, a Velcro is provided at the free end of the drawstring 2, and a Velcro mother tape 8 which can be bonded to the Velcro is provided on the left side of the drawstring 2.

In order to facilitate the sliding of the fixing block 4, an inverted T-shaped slide rail 9 is provided on the outer side of the elastic plate 1, and a T-shaped slide groove 10 that penetrates from left to right is opened on the rear side of the fixing block 4.

In order to facilitate the use of the device, the slide rail 9 is made of elastic material and the elastic plate 1 is made of transparent material.

In order to facilitate the positioning of the pressure plate 6, a slot 11 is provided at the left end of the fixing block 4. The slot 11 opens forward and the left end is connected to the outside. An elastic buckle 12 is provided on the left side of the front end of the pressure plate 6, and the elastic buckle 12 can be inserted into the slot 11.

In order to facilitate the inflation of the extrusion airbag 7, the fixed block 4 has an inflation cavity 13 on both sides, a pressure rod 14 is slidably connected in the inflation cavity 13, and a connecting hole 15 is opened on the opposite sides of the two extrusion airbags 7, which is connected to the inflation cavity 13.

When the utility model is used, the fixed block 4 is first moved, and the fixed block 4 is moved to one side along the slide rail 9, and then the elastic plate 1 is put on the patient's head. During the bending and deformation of the elastic plate 1, the slide rail 9 is also bent and deformed, so that the slide rail 9 squeezes one side of the slide groove 10, resulting in a larger friction force of the slide rail 9, thereby limiting the sliding of the fixed block 4;

Then, when the drawstring 2 passes through the fixing ring 3, the Velcro sub-tape is bonded to the Velcro mother-tape 8, and the elastic plate 1 is fixed on the patient's head. At this time, the end of the hemodialysis tube on the patient's neck is placed in the placement groove 5 on the fixing block 4, and then the pressing plate 6 is swung to squeeze the end of the dialysis tube, and the dialysis tube is preliminarily positioned at the same time;

Then press the pressure rod 14 downward, and the pressure rod 14 pushes the gas in the inflation chamber 13 to flow into the squeezing airbag 7 through the connecting hole 15. The squeezing airbag 7 expands and then further squeezes and fixes the dialysis tube. When the lower end of the pressure rod 14 moves below the connecting hole 15, the gas in the squeezing airbag 7 will not flow out through the connecting hole and will not push the pressure rod 14 to return to its original position, thereby completing the fixation of the dialysis tube.

The utility model has an ingenious structure and is easy to use. By arranging the elastic plate, the elastic belt, the fixing block and the pressing plate, it is convenient for medical staff to fix the temporary dialysis line on the neck. The temporary dialysis line can be fixed on one side of the patient's head, which is beneficial to the patient's postoperative care. At the same time, a slide rail is provided, which is convenient for medical staff to adjust the fixed position of the temporary dialysis line on the neck according to the patient's treatment needs, so as to improve the patient's use effect and comfort, and is beneficial to the operation and use of the patient and the medical staff. The utility model has a simple structure, is easy to operate, has a novel conception and is highly practical.
