Self flow type pollution-free type infusion bottle

Abstract

The automatically flowing pollution-free infusion bottle includes bottle body, bottle cap and bottle stop, and features the inside bag with mouth connected the bottle mouth and the liquefied gas inlet on the bottle body and connected to a miniature liquefied gas tank. The present invention has inside bag pressurized with the liquefied gas, and this avoid the contamination of ambient air to the medicine liquid and eliminates the infusion frame for convenient infusion. The present invention is especially suitable for field first aid.

Description

technical field [0001] The invention relates to an infusion bottle, in particular to an infusion bottle capable of pollution-free infusion and unlimited infusion positions. Background technique [0002] The traditional infusion method belongs to the gravity infusion method, which requires gas-liquid exchange to ensure the infusion, and the ambient air will cause pollution of the liquid medicine in the bottle. Must rely on infusion stand during transfusion, the patient is inconvenient to move freely, especially can't carry out emergency infusion in the field. In order to achieve pollution-free operation, the existing patent literature discloses an infusion bottle with an inner bag structure. The structure is to add a soft inner bag in a normal infusion bottle, and the inner bag is fixedly connected with the mouth of the bottle. Dress medicinal liquid, in order to make medicinal liquid import in the human body, still need hanger, and vent hole is set on the bottle body and co...

AI Technical Summary

Problems solved by technology

In some cases, an air hole with a one-way valve is set on the bottle body, and pressure gas is injected between the bottle body and the inner bag to ensure the infusion. Although this method changes the gravity infusion method, it facilitates the movement of the patient to a certain extent. However, as the infusion proceeds, the pressure will gradually decrease, resulting in uneven flow rate of the liquid medicine, or even inability to flow out, which affects its popularization and use, and the implementation cost is high (need to be equipped with a proprietary pumping device)
