Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of peritoneal dialysis devices, in particular to a sterile operation bag for replacing an external catheter of peritoneal dialysis. Background Art
[0002] Peritoneal dialysis is a commonly used renal replacement therapy for patients with uremia. Compared with hemodialysis, peritoneal dialysis is simple, safe, and effective. It does not require special equipment and is not restricted by venue. Patients can perform daily dialysis treatment at home, and the cost is lower than hemodialysis. Peritoneal dialysis uses the properties of the peritoneum as a semi-permeable membrane. The prepared dialysate is regularly and regularly infused into the patient's peritoneal cavity through a peritoneal dialysis tube by gravity. Due to the difference in solute concentration gradient on both sides of the peritoneum, the solute on the high-concentration side moves to the low-concentration side, and the water moves from the hypotonic side to the hypertonic side. The peritoneal dialysis fluid is continuously replaced to achieve the purpose of removing metabolic products and toxic substances from the body and correcting water and electrolyte imbalance.
[0003] Peritoneal dialysis requires the use of effluent bags, dialysate bags, peritoneal dialysis tubes and peritoneal dialysis external catheters. The effluent bag is an empty bag, and the dialysis bag contains unused dialysate. The peritoneal dialysis tube is a tube that transfers dialysate into / out of the patient's peritoneal cavity, and the peritoneal dialysis external catheter is an external catheter connected to the peritoneal dialysis tube. In the process of changing the dialysate, the effluent (similar to urine) in the peritoneal cavity must first be discharged into the effluent bag through the peritoneal dialysis tube, the peritoneal dialysis external catheter and the catheter in turn; then the dialysate in the dialysis bag is poured into the patient's peritoneal cavity through the catheter, the peritoneal dialysis external catheter and the peritoneal dialysis tube in turn; finally, the peritoneal dialysis external catheter is separated from the effluent bag and the catheter of the dialysate bag, and the dialysis fluid bag is replaced.
[0004] Peritoneal dialysis external catheter needs to be replaced after using for a period of time. In the prior art, the replacement method of peritoneal dialysis external catheter is as follows: first, a container is used to hold an appropriate amount of iodine tincture disinfectant, and the joint of peritoneal dialysis tube and peritoneal dialysis external catheter is placed in the iodine tincture disinfectant in the container, and disinfected for about 15 minutes; then, the joint of peritoneal dialysis tube and peritoneal dialysis external catheter is taken out from the container, and the joint between peritoneal dialysis tube and peritoneal dialysis external catheter is loosened, so that peritoneal dialysis external catheter and peritoneal dialysis tube are separated from each other; then, another container is used to hold an appropriate amount of iodine tincture disinfectant, and the joint of peritoneal dialysis tube is placed in the iodine tincture disinfectant in the container, and disinfected for about 10 minutes; then, the joint of peritoneal dialysis tube is taken out from the container, and the joint of new peritoneal dialysis external catheter is twisted and connected with the joint of peritoneal dialysis tube. The whole operation process staff operates with sterile gloves.
[0005] However, the replacement method of the peritoneal dialysis external catheter in the prior art has the following technical problems: (1) It is inconvenient to use a container to hold iodine disinfectant and soak the peritoneal dialysis tube and the joint of the peritoneal dialysis external catheter. Since one end of the peritoneal dialysis tube is connected to the human abdominal cavity, it is necessary to place the container containing iodine disinfectant on the outside of the human abdominal cavity twice, and each time it needs to be placed for about 15 or 10 minutes. During this process, the container needs to be held steady by hand. If the staff or the patient is not careful, it is easy to overturn the container; (2) The patient's hair and dust impurities in the air can easily enter the container containing iodine disinfectant and contaminate the joint of the peritoneal dialysis tube and the peritoneal dialysis external catheter; (3) The staff needs to wear sterile gloves twice to operate, and the glove wearing process is inconvenient.
