Embodiment Construction

[0021] Since the anticoagulant gastric tube is a common and simple pipeline, and the pipeline itself has not been structurally improved, no accompanying drawings are listed here.

[0022] The present invention is a kind of manufacturing method of anticoagulant gastric tube, comprises the following steps:

[0023] a. Soak the polyurethane tube with ethanol solution for more than 1 hour at room temperature;

[0024] b. Take out the polyurethane tube and let it dry naturally, then rinse it several times with distilled water;

[0025] c. Immerse the polyurethane tube in CaCl 2 solution;

[0026] d. Oscillating polyurethane tube body and CaCl 2 The solution fully combines the two;

[0027] e. Take out the polyurethane tube and dry it naturally;

[0028] f. Uniformly mix heparin sodium solution and sodium alginate solution of the same volume to form a mixed solution, and place the polyurethane tube in the mixed solution;

[0029] g. Oscillate the polyurethane tube and the mixe...

Abstract

The invention discloses a method for making an anticoagulant gastric tube, which comprises the following steps: soaking the polyurethane tube body with ethanol solution for more than 1 hour at room temperature; taking out the polyurethane tube body and drying it naturally, and then rinsing it several times with distilled water; body immersed in CaCl 2 solution; shaking polyurethane tubing and CaCl 2 solution to fully combine the two; take out the polyurethane tube body and dry it naturally; mix heparin sodium solution and sodium alginate solution evenly with the same volume to form a mixed solution, put the polyurethane tube body in the mixed solution; shake the polyurethane tube body and the mixed solution to make the two Mix well; remove polyurethane tube and allow to dry. This production method makes the heparin sodium solution stably attached to the polyurethane tube body, reduces the formation of blood clots related to the gastric tube and external gastric tube in patients after upper gastrointestinal surgery and patients with major digestive bleeding, ensures smooth drainage in a short period of time, and promotes the treatment of patients. of rapid recovery. The invention is used in the field of medical gastric tube.

Description

technical field [0001] The invention relates to the field of medical gastric tubes, in particular to a method for manufacturing an anticoagulant gastric tube. Background technique [0002] At present, the gastric tube commonly used clinically is mostly inserted through the nostril, passes through the pharynx, reaches the stomach through the esophagus, and is used to inject liquid into the stomach to provide the necessary food and nutrition for the patient. For patients after gastrointestinal surgery or patients with gastrointestinal bleeding, it is mainly used to drain gastric juice to observe changes in the condition and speed up the recovery of patients. Common stomach tube materials include polyurethane and silicone, the former has basically replaced the latter because of its superiority in anticoagulation and corrosion resistance. However, in the course of clinical use, for patients with postoperative or gastrointestinal bleeding, we still often find that blood clots bl...
