Integral type respiratory bag and manufacturing method thereof

Abstract

The invention discloses an integral type respiratory bag, comprising a hollow bag body and a joint which is arranged on a bag body connector, wherein a through hole on the joint is communicated with the inner part of the bag body. The integral type respiratory bag is characterized in that the bag body and the joint are integrally manufactured in a mould cavity by coating glue in a vibration manner, heating and molding. The invention further discloses a manufacturing method of the integral type respiratory bag. The bag body of the respiratory bag provided by the invention is manufactured in the glue vibration manner and thicker glue can be coated on a transition part between the side face and the bottom face of the bag body, so as to prevent fisheyes from being generated after the bag body is inflated. The respiratory bag provided by the invention is integrally molded and the joint does not need to be additionally arranged, so that the manufacturing procedure is simplified and the labor cost is reduced; viscose glue or adhesive does not need to be used for sticking so that the problem that the joint drops off due to poor sticking so as to cause air leakage is solved; and therefore, materials are saved and the production cost is reduced. With the adoption of the integral type respiratory bag provided by the invention, the phenomena of causing anaphylactic reaction of a human body and diffusing a pungent smell are avoided and no harm is caused to the human body.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an integrated breathing bag, and also to a manufacturing method of the integrated breathing bag. Background technique [0002] The breathing bag is mainly used as an auxiliary function of anesthesia machine or ventilator, and is mostly used in operating room, emergency department, ICU, ambulance, etc. The breathing bag usually has the following functions: (1) mainly to assist or control breathing to provide patients with sufficient oxygen; (2) to buffer and prevent damage to the lungs by high-pressure airflow; (3) to facilitate observation of the patient's breathing rate , amplitude and airway resistance; (4) facilitate the uniform mixing of anesthesia gas and oxygen; (5) self-scalable expansion, play a greater buffer role for the safety of anesthesia machines and ventilators. [0003] The production process of the existing breathing bag is generally: soak the coagulant ...

AI Technical Summary

Problems solved by technology

[0004] The existing breathing bag has the following defects: (1) Bubbles, trachoma and other defects are easily produced during the molding process of the bag body in the mold. etc.; (2) There are many manufacturing processes for the capsule body, and additional bonding joints are required after the capsule body is manufactured, so the manufacturing process is more complicated; (3) The material of the capsule body is generally rubber latex, and rubber latex There is a large amount of coagulant or various rubber additive residues in the rubber latex, which has certain harmfulness to the human body. In addition, there are proteins in some rubber latex, especially Westerners are prone to allergic reactions to these proteins; (4) due to The joint between the joint and the capsule body is not bonded firmly enough, so the joint is easy to fall off, resulting in air leakage. This not only causes a great waste of material and labor costs, but also if such a phenomenon occurs during the use of the breathing bag , will easily lead to medical accidents; (5) Adhesives or adhesives are chemical materials, which may cause allergic reactions in the human body, and also emit pungent odors, which are harmful to human health

The disadvantages of using the glue-coated process to make the breathing bag are: (1) the thickness of the hollow product made by the glue-coated process is relatively uniform, but the wall of the bag body is thin and can be directly made hollow, while the wall of the joint is relatively thin If it is thick, it is necessary to make the joint solid in the mold cavity of the joint mould, and then open the hole, but it is difficult to achieve this purpose in the enamel process; (2) In the process of gluing, it depends on the rotation of the mold and the use of a higher temperature for heating Set the shape, in the later stage of setting, due to the sharp increase in the fluidity of the glue, there will be colloidal particles, which will affect the quality of the product; (3) It is easy to apply thinner glue to the arc transition part between the side and the bottom of the capsule body by using the enamel process, and the airbag is inflated Finally, there will be fish eyes in the thinner part of the glue; (4) The breathing bag has been fixed when the mold is rotated, and it is easy to generate air bubbles when the mold is rotated. It is very difficult to remove the air bubbles in a vacuum environment
