Description

Technical Field

[0001] The utility model relates to the technical field of peritoneal dialysis, in particular to a peritoneal dialysis catheter outlet flusher. Background Art

[0002] Peritoneal dialysis is a type of dialysis that uses the body's own peritoneum as a dialysis membrane. The dialysate infused into the peritoneal cavity exchanges solutes and water with the plasma components in the capillaries on the other side of the peritoneum to remove metabolic products and excess water retained in the body.

[0003] Peritoneal dialysis catheter outlet infection and tunnelitis are a major problem for peritoneal dialysis patients. Peritoneal dialysis catheter outlet infection is accompanied by tunnelitis. Local use of ointments and wet compresses makes it difficult to enter the inside of the wound, and oral antibiotics have low local concentrations. At present, there is a lack of professional wound irrigators for peritoneal dialysis tunnel and outlet cleaning in clinical practice. Intravenous indwelling needles are used clinically to flush antibiotics at multiple angles in the wound. However, sharp indwelling needles can easily damage the catheter, and the outer sheath of the indwelling needle after the needle core is pulled out is too soft and easily deformed by the outer cuff, and there is no marking on the depth of entry into the wound. In addition, the outlet of the indwelling needle causes the antibiotic water flow to only have a flushing function at the front end, which is not conducive to flushing the wound at multiple angles. And multiple entries into the wound cause obvious pain to the patient. When the catheter is left in the patient's abdomen, it is usually necessary to use a connecting wire or tape to fix the catheter on the abdomen. However, due to the presence of the connecting wire, if the patient accidentally pulls the connecting wire during use, the position of the catheter will be pulled simultaneously, causing the catheter to be out of the correct position, affecting the flushing effect, and may even cause the flushing to fail to proceed normally. At the same time, the change in the position of the catheter may destroy the local sterile environment and make it more likely to cause infection. To address this problem, we proposed a peritoneal dialysis catheter outlet flusher. Utility Model Content
