Problems solved by technology

[0003] First, latex and neoprene air storage bags for anesthesia machines are molded through the dipping process, which involves numerous and complicated processes, low efficiency and uncontrollable product quality;
[0004] Second, latex airbags for anesthesia machines contain protein as raw materials, and some people are allergic to proteins, posing a safety hazard; neoprene airbags for anesthesia machines do not contain protein, but the raw material is synthetic rubber, which is unstable , the product qualification rate is very low, and the cost is high;
[0005] Third, latex and neoprene air storage bags for anesthesia machines are made of natural latex and more than a dozen auxiliary materials, and the pollution is serious during processing;
[0006] Fourth, latex and neoprene air storage bags for anesthesia machines have low temperature resistance and are not suitable for high-temperature sterilization, are not anti-aging, and have a short service life

Embodiment 1

[0030] An injection molding process for corrugated capsules for anesthesia machines. The injection molding process is used to inject two-component liquid silicone into a mold to form a corrugated capsule; the two-component liquid silicone is liquid silicone A and liquid silicone B. :1 weight ratio mixed. Specifically, use a liquid glue injection machine to feed liquid silicone A and liquid silicone B components at a ratio of 1:1. The weight error of the two is between ±0.1g, and then the two-component liquid silicone A and B are fully mixed in the feeder, and then the mixed components are evenly injected into the mold. Its process steps are as follows:

[0031] (1) Fully and evenly mix the components of liquid silica gel A and liquid silica gel B in the feeder in a weight ratio of 1:1;

[0032] Preferably, the components of liquid silicone A and liquid silicone B are fully mixed in the feeder and then evenly enter the mold through 12 glue inlets to ensure the molding quality...

Embodiment 2

[0043]An injection molding process of corrugated capsules for anesthesia machines, using injection molding technology to inject two-component liquid silicone and color paste into the mold to form corrugated capsules; the two-component liquid silicone is liquid silicone A, liquid silicone B components and color paste , and its weight ratio is that the components are mixed in a weight ratio of 49%: 49%: 2%. Specifically, the liquid silicone A component, the liquid silicone B component and the color paste are fed in a weight ratio of 49%: 49%: 2% by using a liquid glue injection machine, and then the two-component liquid silicone A and B And the color paste is fully mixed in the feeding machine, and then the mixed components are evenly injected into the mold. Its process steps are as follows:

[0044] (1) Fully and evenly mix liquid silica gel A, liquid silica gel B components and color paste in the feeder at a weight ratio of 49%: 49%: 2%;

[0045] Preferably, liquid silicone ...

Abstract

The invention discloses a corrugated bag for an anaesthesia machine and an injection molding process thereof.The corrugated bag for the anaesthesia machine is formed by liquid silica gel in an injection molding mode, according to the corrugated bag for the anaesthesia machine, a component A and a component B of the liquid silica gel are fully mixed in a feeding machine and then evenly enter a mold through a gel inlet, the two-component liquid silica gel is shaped and cured by precisely controlling process parameters such as temperature control, pressure maintaining, pressure supplementing and vulcanizing time, finally, a product is taken out by opening the mold, the product produced by high-precision equipment and a mature process is uniform in wall thickness and full in vulcanization, the elasticity and the deformation resistance are fully guaranteed, and the product is coated by a high polymer material after being formed, And the coating has smooth and wear-resistant effects, so that the friction between the coating and equipment matching parts in the working process is reduced, and better use precision is achieved. The material is good in stability, high in biocompatibility and harmless to a human body.

Description

technical field [0001] The invention relates to a corrugated bag for an anesthesia machine and an injection molding process thereof. Background technique [0002] The corrugated bag for anesthesia machine acts on the regular mechanical movement of the anesthesia ventilator to meet the quantitative and fixed-frequency delivery of anesthesia by the anesthesia machine. Therefore, the corrugated bag for anesthesia machine needs to have uniform wall thickness and controllable and precise movement rules. The corrugated capsules of existing anesthesia machines are formed by latex dipping, and very few are formed by neoprene dipping. These materials have the following defects: [0003] First, latex and neoprene air storage bags for anesthesia machines are molded through the dipping process, which involves numerous and complicated processes, low efficiency and uncontrollable product quality; [0004] Second, latex airbags for anesthesia machines contain protein as raw materials, and...
