Problems solved by technology

[0002] Gastrostomy is a way of palliative treatment for patients with advanced esophageal cancer. A tube is left in the abdomen to improve the patient's diet and nutrition, and at the same time achieve the purpose of treatment as much as possible. It is a common treatment method. The tube connection directly affects the patient. The quality of life of the gastrostomy tube is currently too small to be connected to an empty needle or an infusion set to inject food for the patient. It is often made temporarily in clinical practice (use a disposable drainage bag to terminate the positive pressure connector), but the airtight performance is not good, and food It is easy to overflow, leading to local dressing contamination. There is no control device (switch) in the pipeline, and the food is easy to flow back into the pipeline after injection, which is not conducive to the improvement of the quality of life of patients and pipeline management, and the cost of consumables for positive pressure joints is high

Abstract

The invention discloses a gastrostomy in-vitro connecting device which comprises an extension tube, a tube cap and a clip. A thread is formed on the outer side of one end of the extension tube, the tube cap is connected to the outer side of the thread, and the clip is installed on the outer side of the extension tube. The device can effectively prevent food backflow, keep skin dressing around ostomy clean and dry and prevent infection and is easy to manufacture, can effectively control the cost, and has good clinical application prospects.
