Problems solved by technology

Although some existing patented technologies have improved the infusion bottle, such as 94229621.4 "multifunctional liquid bottle", the bottom of the infusion glass bottle is preset with a supplementary air inlet. Passing through the liquid medicine reduces the pollution of the germs in the air to the liquid medicine, but there is still the disadvantage that the air needs to be in contact with the liquid medicine, and the purpose of eliminating the pollution of the liquid medicine by harmful bacteria in the air cannot be completely achieved

Abstract

The aseptic infusion device includes needle, infusion tube, flow rate display, air replenishing tube, etc. It features the air replenishing tube with a ventilating cavity connected to its one end andthe ventilating cavity is provided with a aseptic air supplying unit for disinfection. The aseptic infusion device makes air enter to the glass bottle after being sterilized fully and this can prevent medicine liquid from being contaminated by pathogenic bacteria in air.

Description

Technical field: [0001] The invention relates to an infusion device, in particular to an aseptic infusion device. Background technique: [0002] It is well known that when people are treated after being ill at present, the mode of infusion is often adopted to quickly disperse the medicinal liquid to the whole body through veins, so as to speed up the treatment. But the transfusion method that adopts for a long time stays at the state that uses glass bottle to store medicinal liquid at present, and air must be supplemented to it to output the state of medicinal liquid during infusion. In this transfusion method and device, the supplemented air must pass through medicinal liquid. Contamination of the liquid medicine, especially the hospital is a place where various germs are concentrated. There are many kinds of germs in the air, which will lead to the pollution of the liquid medicine after entering the liquid medicine. Cause other sequelae, affect people's health. Although ...
