AI Technical Summary
Existing disposable infusion devices (intake gravity infusion type) cannot effectively block viral microorganisms and toxic gases in the medical ambient air into the infusion system, resulting in adverse infusion events.
A disposable infusion air replenishment bag consisting of soft air storage bags, switch connectors and sterile clean gas are designed. By connecting the air inlet of the disposable infusion device, the sterile clean gas is automatically replenished to replace the air in the infusion system.
The closed gas replenishment of the infusion system during the infusion process is achieved, reducing the inflow of viral microorganisms and toxic gases, reducing the incidence of adverse infusion events, and simplifying the product structure, avoiding the pipe clamping caused by the use of clips.

Abstract
Description
Technical Field
[0001] The invention belongs to an infusion and blood transfusion apparatus in medical equipment and is used for supplementing sterile clean gas into an infusion system during infusion. Background Art
[0002] Disposable infusion sets (intake gravity infusion type) are Class III medical devices that must be strictly controlled for safety and effectiveness. They are characterized by large-scale use, high risk, and many complaints and reports. During use, suspected adverse events such as chills, high fever, nausea, and vomiting that may cause or may cause human harm may occur. The current disposable infusion set (intake gravity infusion type) uses the principle that the internal pressure of the infusion system formed by atmospheric pressure and liquid static pressure is higher than the human venous pressure for infusion. To prevent microorganisms from entering the infusion system, there is an air filter on the air intake device. The size of viral microorganisms is between 20nm and 10um. The air filter with a pore size of 0.5um on the air intake device cannot effectively block all viral microorganisms and toxic gases in the air of the medical environment from entering the infusion system. These gas inputs will contaminate the liquid medicine, thereby causing adverse infusion events. Summary of the invention
[0003] The purpose of the present invention is to provide a disposable infusion air-replenishing bag composed of a soft air storage bag, a switch connector and sterile clean gas. One end of the switch connector is connected to the soft air storage bag, and the other end can be connected to the air inlet of the disposable infusion set (air intake gravity infusion type). Before infusion, the medical staff connects the air inlet on the disposable infusion set (air intake gravity infusion type) to the switch connector of the disposable infusion air-replenishing bag. During infusion, open the switch connector on the disposable infusion air-replenishing bag and it can be used normally. When the gas pressure in the infusion bottle is lower than the atmospheric pressure, under the action of atmospheric pressure, the sterile clean gas in the soft air storage bag will be automatically replenished into the infusion system through the air inlet on the disposable infusion set (air intake gravity infusion type). The whole process realizes closed normal gravity infusion.
[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: one end of the switch connector is connected to a soft gas storage bag, in which sterile clean gas is stored, and the other end can be connected to the air inlet of a disposable infusion set (air intake gravity infusion type), and a rubber sealing ring is provided in the switch connector. Before infusion, the medical staff connects the air inlet on the disposable infusion set (air intake gravity infusion type) to the switch connector of the disposable infusion gas replenishment bag, and opens the switch connector on the disposable infusion gas replenishment bag during infusion. When the gas pressure in the infusion bottle is lower than the atmospheric pressure, the sterile clean gas in the soft gas storage bag will automatically enter the infusion system for replenishment through the air inlet on the disposable infusion set (air intake gravity infusion type), and the whole process realizes closed normal gravity infusion.
[0005] The soft air storage bag of the disposable infusion air replenishing bag stores sterile clean gas. When the gas pressure in the infusion bottle is lower than the atmospheric pressure, under the action of the atmospheric pressure, the sterile clean gas in the soft air storage bag will automatically enter the infusion system for replenishment through the air inlet on the disposable infusion set (air intake gravity infusion type), and the whole process realizes closed normal gravity infusion.
[0006] Compared with the disposable infusion set (intake gravity infusion type), the disposable infusion set (intake gravity infusion type) alone replenishes the infusion system with medical environment air containing viruses, microorganisms and toxic gases less than 0.5um. The disposable infusion set (intake gravity infusion type) is connected with the disposable infusion set of the present invention, and sterile clean gas is replenished into the infusion system. Compared with the disposable infusion set (application number: 202322432429.5), the structure is simpler and can avoid the phenomenon of pipeline clamping caused by the use of clamps. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 The schematic diagram of the structure of the disposable infusion air-invigorating bag of the present invention is shown in FIG. One end of the switch connector 1 on the disposable infusion air-invigorating bag of the present invention is connected to the soft air storage bag 3, in which sterile clean gas 4 is stored, and the other end can be connected to the air inlet of the disposable infusion set (air-intake gravity infusion type), and a rubber sealing ring 2 is arranged in the switch connector 1.
[0010] When using the disposable infusion air-replenishing bag of the present invention, before infusion, the medical staff first aligns the air inlet on the disposable infusion set (air-intake gravity infusion type) with the rubber sealing ring 2 in the switch connector 1 on the disposable infusion air-replenishing bag, and then locks it and connects it to the switch connector 1. During infusion, the switch connector 1 on the disposable infusion air-replenishing bag is opened, and when the gas pressure in the infusion bottle is lower than the atmospheric pressure, under the action of the atmospheric pressure, the sterile clean gas 4 in the soft gas storage bag 3 will enter the infusion system through the air inlet on the disposable infusion set (air-intake gravity infusion type) for replenishment, and the whole process realizes closed normal gravity infusion.
[0011] The disposable infusion air-replenishing bag provided by the present invention is connected to a disposable infusion set (air intake gravity infusion type) for use, and sterile clean gas is added to the infusion system. The unit uses a disposable infusion set (air intake gravity infusion type), and the air from the medical environment containing viruses, microorganisms and toxic gases less than 0.5um is added to the infusion system. The disposable infusion air-replenishing bag of the present invention is connected to a disposable infusion set (air intake gravity infusion type) for use, which can reduce the occurrence of adverse events of infusion. The disposable infusion air-replenishing bag of the present invention has a simple product structure, is easy to produce, and is safe and effective.
