Embodiment 1

[0050] Embodiment 1, the influence of different antibacterial agent combinations on the antibacterial performance of medical esophageal catheter

[0051] According to QB / T2591-2003 "Antibacterial Plastics - Antibacterial Performance Test Method and Antibacterial Effect", the antibacterial test was carried out on the esophageal catheter made of each group of compound antibacterial agents in the table below, and the test results are shown in Table 1.

[0052] Table 1 Test results

[0053]

[0054] It can be seen from the above table 1 that the antibacterial rate of the esophageal catheter prepared by the combination of forsythia oil and zinc silicate as a composite antibacterial agent is as high as 99.5%, and has a strong antibacterial effect; The antibacterial effect of composite antibacterial agent composed of nano titanium dioxide is poor.

Embodiment 2

[0055] Embodiment 2, a kind of medical esophageal catheter

[0056] The medical esophageal catheter described in Example 2 of the present invention is made of the following raw materials in parts by weight: 60 parts of PVC resin, 0.6 part of calcium zinc stabilizer, 2 parts of hydrogenated soybean oil, 30 parts of plasticizer, 2 parts of nanocrystalline cellulose part and 3 parts of composite antibacterial agent, wherein, described plasticizer is made up of acetyl tri-n-butyl citrate and O-acetyl ricinoleic acid methyl ester by the weight ratio of 1:0.03, and described composite antibacterial agent is made up of forsythia Oil and zinc silicate are composed in a weight ratio of 1:0.06.

[0057] Preparation:

[0058] Mix PVC resin, hydrogenated soybean oil and plasticizer evenly, stir at 95°C for 25 minutes, cool to room temperature, add composite antibacterial agent, calcium zinc stabilizer and nano-microcrystalline cellulose, and continue stirring for 10 minutes.

Embodiment 3

[0059] Embodiment 3, a kind of medical esophageal catheter

[0060] The medical esophageal catheter described in Example 3 of the present invention is made of the following raw materials in parts by weight: 40 parts of PVC resin, 0.2 part of calcium zinc stabilizer, 1 part of hydrogenated soybean oil, 20 parts of plasticizer, 1 part of nanocrystalline cellulose part and 2 parts of composite antibacterial agent, wherein, described plasticizer is made up of acetyl tri-n-butyl citrate and O-acetyl ricinoleic acid methyl ester by the weight ratio of 1:0.01, and described composite antibacterial agent is made of forsythia Oil and zinc silicate are composed in a weight ratio of 1:0.05.

[0061] The preparation method refers to Example 2.

Abstract

The invention belongs to the field of medical instruments and particularly relates to a medical esophageal catheter and a preparation method thereof, and a ventilating device. The medical esophageal catheter is made from the following materials, by weight: PVC (polyvinyl chloride) resin, calcium-zinc stabilizer, hydrogenated soybean oil, a plasticizer and a compound antibacterial agent, wherein the plasticizer is composed of acetyl tri-n-butyl citrate and methyl O-acetylricinoleate according to a weight ratio of 1:(0.01-0.06); the medical esophageal catheter has the advantages of safety, environment friendliness, stability, ideal antibacterial effect, zero peculiar odor and good simplicity of processing and forming and is suitable for wide range of popularization and application; the invention also provides the ventilating device capable of blocking esophagus and relieving stomach and intestines, and the ventilating device can effectively prevent backflow and mistaken inhalation, can relief the stomach and intestines during ventilating and has the advantages of simple structure, high embedding speed, good simplicity of operation, and good safety and reliability.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a medical esophageal catheter, a preparation method thereof and a ventilation device. Background technique [0002] Endotracheal intubation is an important measure to establish an artificial airway, ensure the smoothness of the airway, and the body's oxygen demand and carbon dioxide excretion. It is an indispensable basic technology for modern anesthesiology and modern emergency medicine. The standard endotracheal tube used in anesthesia is a metal anti-laser endotracheal tube with double water balloons, but its popularization and application are limited due to its high price, easy reflection of laser beams to cause accidental injury, rough surface of endotracheal tube and easy damage to the normal mucosa of the vocal cords, etc. . At present, ordinary polyvinyl chloride (PVC) tracheal tubes are mostly used in China. Its price is low, its surface is smooth, and the inc...
