Description

Technical Field

[0001] The utility model relates to an internally fixed anti-slip peritoneal effusion drainage tube, belonging to the technical field of medical equipment. Background Art

[0002] Ascites is the accumulation of free fluid in the abdominal cavity exceeding 200 ml due to various reasons. It is also called ascites and is one of the common symptoms in gastroenterology. There are many causes of ascites, common causes include cirrhosis, tumor lesions, heart failure, abdominal tuberculosis, vascular origin (venous obstruction or stenosis), renal insufficiency, autoimmune diseases, pancreatic diseases, malnutrition, etc. Abdominal puncture and placement of drainage tubes are common clinical procedures for patients with ascites. Through the analysis of the physical and chemical properties, microbiology and cytology of ascites, the nature of ascites can be clarified, which is helpful for the diagnosis of the disease. When a large amount of ascites causes severe abdominal distension, chest tightness, shortness of breath, oliguria and other symptoms that make it difficult for patients to bear, ascites drainage can be used to relieve the symptoms.

[0003] Drainage tube slippage is a common problem with abdominal catheterization. Currently, abdominal catheterization involves external fixation of the catheter on the surface of the abdominal wall skin, usually with various types of dressings. However, in actual clinical applications, the drainage tube is prone to slipping outward due to high intra-abdominal pressure, improper patient position, gravity of the drainage bag, improper care by family members, and other reasons. Slippage of the drainage tube can cause catheter obstruction and poor drainage of ascites. Some patients put a small amount of slipped catheter back into the abdominal cavity on their own, increasing the risk of abdominal infection. Re-catheterization not only increases the patient's pain, but also increases the patient's financial burden.

[0004] Puncture point leakage is also a thorny problem after peritoneal catheterization. Most patients with ascites have severe underlying diseases and poor overall nutritional status. Ascites causes high abdominal pressure, high abdominal wall tension, and thin abdominal wall, which causes the puncture point hole to be large and loose, making it easy for the puncture point to leak. Puncture point leakage can cause local skin redness, inflammation, and even ulceration, aggravating the primary disease; continuous leakage from the puncture point causes the local dressing to be always soaked, increasing the patient's discomfort and psychological burden; frequent dressing changes not only increase the patient's economic burden, but also increase the workload of medical care.

[0005] Currently, the main approach to addressing the problems of drainage tube slippage and persistent fluid exudation at the puncture site after abdominal catheterization is to strengthen education, enhance nursing care, and frequently change dressings, but this does not solve the fundamental problem. Summary of the invention

[0021] This embodiment provides an internally fixed and non-slip peritoneal drainage tube, such as Figures 1-2 As shown, it includes a drainage tube body 1, which is a coaxial double-lumen tube with an inner lumen and an outer lumen. One end of the drainage tube body 1 is provided with a drainage end 2 and the other end is provided with an interface plug 4. The drainage end 2 is in the shape of a pigtail and is provided with a plurality of drainage side holes 3; a balloon 5 is sleeved on the drainage tube body 1 near the drainage end 2, and the drainage tube body 1 runs through the balloon 5. A water injection pipe 6 and a liquid extraction pipe 7 are respectively fixedly connected to the interface plug 4. The water injection pipe 6 is connected to the outer lumen of the drainage tube body 1 and the balloon 5. Water is injected into the balloon 5 through the water injection pipe 6 to fill the balloon. The balloon 5 is empty before water injection and is filled after water injection. The liquid extraction pipe 7 is connected to the inner lumen of the drainage tube body 1, and the head end of the water injection pipe 6 is connected to a water injection pipe joint 6-1, and the head end of the liquid extraction pipe 7 is connected to a liquid extraction pipe joint 7-1. There is also an external fixation reserved section 8 between the balloon 5 and the interface plug 4. The external fixation reserved section 8 refers to a 4-6 cm external fixation section reserved on the basis of the existing length of the drainage tube. The external fixation reserved section 8 can be adhered to the patient's skin to further fix the drainage tube. The length of the drainage tube body 1 is 20-30 cm, and the thickness is 5-6F.
