Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, and more specifically, to an external fixing device for preventing the displacement of peritoneal dialysis tubes. Background Art
[0002] The peritoneal dialysis tube is an important medical device, which consists of a catheter, a lead wire and a Dacron cuff. Its special design (such as the side holes at the insertion end and the Y-shaped two-arm structure) plays a key role in the treatment of end-stage renal disease. This kind of catheter is mainly used for renal replacement therapy, especially providing an important treatment way for patients with renal failure caused by various reasons. Through the peritoneal dialysis tube, the dialysate can be smoothly introduced into the abdominal cavity. By using the semi-permeable membrane function of the peritoneum, the excess water and toxins in the patient's body can be discharged out of the body, so as to effectively maintain the balance of water, electrolyte and acid-base. Through reasonable catheterization methods and daily care, patients can better manage their health conditions and improve their quality of life.
[0003] In medical practice, it usually needs to be indwelled in the patient's body for a long time. However, in the patient's daily life, the dialysis tube may be subjected to accidental external pulling force, resulting in its horizontal or vertical displacement, and this displacement may cause damage to the fistula in the patient's body. Content of the Utility Model
[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the utility model provide an external fixing device for preventing the displacement of peritoneal dialysis tubes. The technical problem to be solved by the present invention is that the existing dialysis tubes are easily pulled accidentally to cause displacement, resulting in damage to the fistula.
[0005] To achieve the above purpose, the utility model provides the following technical solutions: An external fixing device for preventing the displacement of peritoneal dialysis tubes, including a base plate, a fixing sleeve is fixedly connected inside the base plate, a second rubber ring is fixedly connected to the back of the base plate, six limiting columns are fixedly connected to the front of the base plate, a fixing piece is arranged on the front of the base plate and is movably sleeved outside the six limiting columns, a first rubber ring is fixedly connected to the back of the fixing piece, a pressing plate is movably sleeved outside the six limiting columns, and the fixing piece is located between the pressing plate and the fixing piece. Fixing screws are threadedly sleeved inside three of the limiting columns, and the three fixing screws are equally spaced around the fixing sleeve;
[0006] A dialysis hose is movably sleeved inside the fixing sleeve, a fixing ring is fixedly sleeved outside the fixing sleeve, a fixing ring is fixedly sleeved outside the dialysis hose, and a plurality of elastic rubber ropes are fixedly connected between the fixing ring and the fixing ring.
[0007] Such as Figures 1-3As shown, the specific implementation method is as follows: By attaching the first rubber ring to the patient's skin, the base plate can be preliminarily fixed. Then, by attaching the second rubber ring to the patient's skin, the base plate can be further fixed, preventing the dialysis hose from shifting and causing harm to the patient.
[0008] The elastic rubber cord provided can prevent the part of the dialysis hose inside the patient's body from moving, thus avoiding injury to the patient. By removing the three fixing screws, the fixing plate can be replaced to prevent the second rubber ring from falling off after long-term use.
[0009] In a preferred embodiment, a plurality of uniformly distributed heat dissipation holes are provided inside the fixing plate, and a plurality of air permeable strips are provided inside the base plate.
[0010] The provision of a plurality of heat dissipation holes and a plurality of air permeable strips can prevent the patient's skin from becoming overly stuffy and uncomfortable, and at the same time prevent sweat accumulation from causing infection at the fistula site.
[0011] In a preferred embodiment, the base plate is in the shape of an inverted bowl.
[0012] The inverted bowl-shaped base plate can prevent direct extrusion of the fistula site and cause damage to the fistula site.
[0013] In a preferred embodiment, a first rubber sleeve is fixedly connected inside the fixing sleeve, a second rubber sleeve is fixedly connected inside the fixing ring, and the dialysis hose is in close fit with both the first rubber sleeve and the second rubber sleeve.
[0014] The provision of the first rubber sleeve and the second rubber sleeve can increase the friction force and prevent the dialysis hose from moving.
[0015] In a preferred embodiment, a section of the dialysis hose between the fixing ring and the fixing collar is bent.
[0016] The bent dialysis hose can play a buffering role and prevent the dialysis hose from directly pulling on the fistula site and causing damage.
[0017] The technical effects and advantages of the present utility model:
[0018] 1. By threading the dialysis hose into the fixing sleeve and the fixing ring, and then attaching the first rubber ring to the patient's skin, the base plate can be preliminarily fixed. Then, by attaching the second rubber ring to the patient's skin, the base plate can be further fixed, preventing the dialysis hose from shifting and causing harm to the patient.
[0019] 2. The deformation of the elastic rubber cord provided can play a buffering role, preventing the part of the dialysis hose inside the patient's body from moving, thus avoiding injury to the patient.
[0020] 3. The fixing piece can be replaced by removing three fixing screws, avoiding the detachment of the second rubber ring after long-term use. Brief Description of the Drawings
