Description

Technical Field

[0001] The invention belongs to an infusion and blood transfusion apparatus in medical equipment and is used for supplementing 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 an infusion air-inflating bag (with air) composed of a soft air storage bag, a pipeline, a clamp, clean gas and an air inlet connector, wherein a rubber sealing ring is arranged inside the air inlet connector. The infusion air-inflating bag (with air) can be connected to a disposable infusion set (air intake gravity infusion type) for use. Before infusion, the medical staff connects the air inlet on the disposable infusion set (air intake gravity infusion type) to the air inlet connector of the infusion air-inflating bag (with air). During infusion, open the clamp on the infusion air-inflating bag (with air) pipeline and it can be used normally. When the gas pressure in the infusion bottle is lower than the atmospheric pressure, under the action of the atmospheric pressure, the 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-mentioned purpose, the technical solution adopted by the present invention is: a clamp is provided on the pipeline, one end of which is connected to a soft air storage bag, and the other end is connected to an air inlet connector. Clean gas is stored in the soft air storage bag, and a rubber sealing ring is provided in the air inlet connector. Before infusion, medical staff connects the air inlet on the disposable infusion set (air intake gravity infusion type) to the air inlet connector of the infusion air replenishment bag (with air). During infusion, open the clamp on the infusion air replenishment bag (with air) pipeline. When the gas pressure in the infusion bottle is lower than the atmospheric pressure, the 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). The whole process realizes closed normal gravity infusion.

[0005] The soft air storage bag of the infusion air replenishing bag (with air) stores clean gas. When the gas pressure in the infusion bottle is lower than the atmospheric pressure, under the action of the atmospheric pressure, the 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] The above-mentioned infusion air-replenishing bag (with air) provided by the present invention is compared with the air-intake device on the disposable infusion set (air-intake gravity infusion type): when connected with the infusion air-replenishing bag (with air) of the present invention, the clean gas from the non-medical environment is replenished into the infusion system. When using the air-intake device on the disposable infusion set (air-intake gravity infusion type), the air entering the infusion system is from the medical environment containing viruses, microorganisms and toxic gases less than 0.5um, which will contaminate the liquid medicine and cause adverse infusion events. Compared with the infusion air-replenishing device (application number: 202322293197.X): it has the advantages of simpler structure and lower manufacturing cost. Compared with the infusion air-replenishing bag (application number: 202322432429.5): it has the advantages of simpler production process and prevention of secondary contamination of sterilization.

[0009] Figure 1 The schematic diagram of the structure of the infusion gas-invigorating bag (with gas) of the present invention is shown in FIG. The pipe 3 on the infusion gas-invigorating bag (with gas) of the present invention is provided with a clip 4, one end of which is connected to a soft gas storage bag 5, and the other end is connected to an air inlet connector 1, the soft gas storage bag 5 stores clean gas 6, and the air inlet connector 1 has a rubber sealing ring 2.

[0010] When using the infusion gas-replenishing bag (with gas) of the present invention, before infusion, the medical staff first aligns the gas inlet on the disposable infusion set (gas-intake gravity infusion type) with the rubber sealing ring 2 in the gas inlet connector 1 on the infusion gas-replenishing bag (with gas), and then locks it and connects it to the gas inlet connector 1. During infusion, open the clamp 4 on the infusion gas-replenishing bag (with gas) pipeline 3. When the gas pressure in the infusion bottle is lower than the atmospheric pressure, under the action of atmospheric pressure, the clean gas 6 in the soft gas storage bag 5 will enter the infusion system through the gas inlet on the disposable infusion set (gas-intake gravity infusion type) for replenishment. The whole process realizes closed normal gravity infusion.

[0011] The above-mentioned infusion air-replenishing bag (with air) provided by the present invention is connected to the air inlet on the disposable infusion set (air intake gravity infusion type) for use, and the clean gas from the non-medical environment is replenished into the infusion system. The air intake device on the disposable infusion set (air intake gravity infusion type) is used to allow the air from the medical environment containing viruses, microorganisms and toxic gases smaller than 0.5um to enter the infusion system. The infusion air-replenishing bag (with air) of the present invention is connected to the air inlet of the disposable infusion set (air intake gravity infusion type) for use, which can reduce the occurrence of adverse events of infusion. The infusion air-replenishing bag (with air) of the present invention has a simple product structure, is easy to produce, and is safe and effective.
