Abstract
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 a disposable infusion gas-replenishing bag (with gas) composed of a soft gas storage bag, a switch connector and clean gas. One end of the switch connector is connected to the soft gas storage bag, and the other end can be connected to the gas inlet of the disposable infusion set (gas-intake gravity infusion type). Before infusion, medical staff connect the gas inlet on the disposable infusion set (gas-intake gravity infusion type) to the switch connector of the disposable infusion gas-replenishing bag (with gas). During infusion, open the switch connector on the disposable infusion gas-replenishing bag (with gas) 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 clean gas in the soft gas storage bag will be automatically replenished into the infusion system through the gas inlet on the disposable infusion set (gas-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 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 (with gas), and opens the switch connector on the disposable infusion gas replenishment bag (with gas) during infusion. When the gas pressure in the infusion bottle is lower than the atmospheric pressure, the clean gas in the soft gas storage bag will automatically 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.
[0005] The soft air storage bag of the disposable 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 disposable infusion air-replenishing bag (with air) provided by the present invention is 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 and used with the disposable infusion air-replenishing bag (with air) of the present invention, and the clean gas of the non-medical environment is replenished into the infusion system. Compared with the infusion air-replenishing bag (application number: 202322432429.5): the structure is simpler, and the phenomenon of pipeline clamping caused by the use of clamps can be avoided. Compared with the disposable infusion air-replenishing bag (application number: 202322788808.8): it has the advantages of simpler production process and prevention of secondary contamination of sterilization. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a schematic structural diagram of a disposable infusion air-replenishing bag (with air) of the present invention.
[0008] In the figure: 1- switch connector; 2- rubber sealing ring; 3- soft gas storage bag; 4- clean gas. Implementation
[0009] Figure 1 The schematic diagram of the structure of the disposable infusion gas-inflating bag (with gas) of the present invention is shown in FIG. One end of the switch connector 1 on the disposable infusion gas-inflating bag (with gas) of the present invention is connected to a soft gas storage bag 3, in which clean gas 4 is stored, and the other end can be connected to the gas inlet of a disposable infusion set (intake gravity infusion type), and a rubber sealing ring 2 is provided in the switch connector 1.
[0010] When using the disposable 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 switch connector 1 on the disposable infusion gas-replenishing bag (with gas), and then locks it and connects it to the switch connector 1. During infusion, the switch connector 1 on the disposable infusion gas-replenishing bag (with gas) is opened. When the gas pressure in the infusion bottle is lower than the atmospheric pressure, under the action of the atmospheric pressure, the clean gas 4 in the soft gas storage bag 3 will enter the infusion system through the gas inlet on the disposable infusion set (gas-intake gravity infusion type) for replenishment, and the whole process realizes closed normal gravity infusion.
[0011] The disposable infusion air-replenishing bag (with air) provided by the present invention is connected to a disposable infusion set (air intake gravity infusion type) for use, and the clean gas from a non-medical environment is replenished into the infusion system. When the disposable infusion set (air intake gravity infusion type) is used alone, the air from the medical environment containing viruses, microorganisms and toxic gases smaller than 0.5um is replenished into the infusion system. The disposable infusion air-replenishing bag (with air) 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 (with air) of the present invention has a simple product structure, is easy to produce, and is safe and effective.
