Problems solved by technology

[0004] The tube body in the above-mentioned technology is relatively hard, and after being inserted into the trachea, since the respiratory tract has not been kept warm and moisturized by the throat, the rapid breathing on its own is more likely to cause a large amount of water loss, which will cause certain damage to the mucous membrane in the trachea and poor comfort

preparation example 1

[0060] A kind of modified polyvinyl chloride, its preparation steps are as follows:

[0061] a. Modification treatment: first mix polyvinyl chloride resin, modified emulsion and initiator in a weight ratio of 1:0.1:0.005, that is, stir at 80°C for 5min at a speed of 80r / min, and then heat up to 180°C °C, under vacuum conditions, at a speed of 200r / min, stir for 4h to prepare the modified material;

[0062] The modified emulsion is composed of tributyl citrate, tetramethyltetravinylcyclotetrasiloxane, and octamethylcyclotetrasiloxane in a weight ratio of 1: 0.01:1;

[0063] The initiator is sodium trimethylsilanolate;

[0064] b. Softening treatment: Mix the modified material, lubricant and surfactant in a weight ratio of 1:0.1:0.05, that is, stir at a speed of 80r / min for 1h at 80°C to obtain a modified polychloride vinyl.

[0065] The lubricant is calcium stearate;

[0066] The surfactant is coconut acid diethanolamide.

preparation example 2

[0068] A modified polyvinyl chloride, the difference from Preparation Example 1 is that the preparation steps are as follows:

[0069] a. Modification treatment: Stir the polyvinyl chloride resin, modified emulsion and initiator at 90°C at a speed of 80r / min for 7.5min, then raise the temperature to 190°C, and stir at 200r / min under vacuum. The rotating speed, stir 4.5h, make modified material;

[0070] b. Softening treatment: Stir the modified material, lubricant and surfactant at 90°C at a speed of 80r / min for 1.5h to prepare modified polyvinyl chloride.

preparation example 3

[0072] A modified polyvinyl chloride, the difference from Preparation Example 1 is that the preparation steps are as follows:

[0073] a. Modification treatment: Stir the polyvinyl chloride resin, modified emulsion and initiator at a speed of 80r / min for 10min at 100°C, then raise the temperature to 200°C, and stir at a speed of 200r / min under vacuum. Rotating speed, stirring for 5h, obtained modified material;

[0074] b. Softening treatment: Stir the modified material, lubricant and surfactant at 100°C for 2 hours at a speed of 80r / min to obtain modified polyvinyl chloride.

Abstract

The invention relates to the technical field of tracheal surgical instruments, in particular to a tracheostomy tube body and a preparation method thereof. The tracheostomy tube body comprises the following components in parts by weight: 100-150 parts of polyvinyl chloride resin; 20-50 parts of a plasticizer; 5-10 parts of a stabilizer; 200 to 250 parts of modified polyvinyl chloride; the preparation method of the modified polyvinyl chloride comprises the following steps: a, modification treatment: heating and mixing polyvinyl chloride resin, a modified emulsion and an initiator to prepare a modified material, wherein the modified emulsion is prepared from tributyl citrate, tetramethyl tetravinyl cyclotetrasiloxane and octamethyl cyclotetrasiloxane; the modified emulsion is prepared from tributyl citrate, tetramethyl tetravinyl cyclotetrasiloxane and octamethyl cyclotetrasiloxane; b, softening treatment: heating and mixing the modified material, a lubricant and a surfactant to prepare the modified polyvinyl chloride. The tracheostomy tube body has excellent flexibility, and the comfort level is higher while mucosa in the trachea is not prone to being damaged after the tracheostomy tube body is inserted into the trachea.

Description

technical field [0001] The present application relates to the technical field of tracheal surgery instruments, more specifically, it relates to a tracheotomy intubation tube body and a preparation method thereof. Background technique [0002] In respiratory diseases, tracheostomy is often used for the treatment of patients with symptoms such as laryngeal dyspnea, respiratory dysfunction, or dyspnea caused by retention of secretions in the lower airway. Tracheotomy, that is, to cut the trachea of ​​the neck and put in a tracheotomy tube to provide a breathing channel for adult patients who need anesthesia, artificial ventilation or other assisted breathing through the tracheotomy tube. [0003] The tracheostomy tube in the related art includes a tube body made of polyvinyl chloride through mixing, extrusion, injection molding, blow molding and other processes. One end of the tube body is connected with a plug joint to connect to external equipment, and the other end is used ...
