Infusion dripping bucket and infusion apparatus thereof

Abstract

The invention discloses an infusion dripping bucket and an infusion apparatus thereof. The infusion dripping bucket comprises a dripping bucket main body and an exhaust valve, wherein the exhaust valve comprises a base and an exhaust and drainage pipe which extends upwards from the upper surface of the base; the bottom of the base is adaptive to the base of the dripping bucket main body; at least two action forces can be exerted on the dripping bucket main body by virtue of the base; and the two action forces are located on a same straight line, so that stress between round sidewalls of the base and the dripping bucket main body as well as stress between the bottom of the base and the dripping bucket main body can be completely sealed. The infusion dripping bucket provided by the invention is simple and skilful in structure, a space in the base is diminished, and sealing performance of the infusion dripping bucket is greatly enhanced due to a special sealing structure in the dripping bucket, so that incomplete exhaust due to a problem on sealing is prevented to a great extent, and subsequent medical accidents are avoided. With the application of the infusion dripping bucket which has an automatic exhaust device, air in the dripping bucket can be completely discharged to the greatest extent, so that infusion safety of the infusion apparatus is enhanced.

Description

technical field [0001] The invention relates to an infusion dripping funnel and an infusion set, in particular to an infusion device with a self-venting infusion dripping funnel. Background technique [0002] The infusion sets for clinical trials are generally mainly composed of bottle stopper piercers, drip funnels, hoses, flow regulators, and joints. When it rises to a certain height, put the drip funnel in order to discharge the air in the drip funnel. If the operation is improper, the liquid and gas in the drip funnel will mix into the hose, which will form air bubbles and cause safety hazards. If the control is not proper, it will If the liquid level in the drip funnel is too high or too low, the liquid level in the drip funnel is too high, which is not conducive to the observation of the number of infusion drops. If the liquid level in the drip funnel is too low, it may cause a mixture of liquid and gas to enter the hose, causing a safety hazard. [0003] The patent w...

AI Technical Summary

Problems solved by technology

[0004] In the above technology, due to the large space inside the base, it is easy to form air bubbles in the inner part of the base during the first exhaust, and there is a hidden danger of entering the human body. The reason is that the liquid The liquid enters from the liquid inlet on the upper part of the dripping funnel of the infusion set, flows through the automatic exhaust valve, enters the inner part of the base through the exhaust liquid guide groove on the exhaust catheter, and finally flows to the liquid outlet at the lower end of the dropping funnel to enter the human body. Due to the relatively large space inside the base, when the liquid flows downward, the air cavity inside the base is not filled, resulting in the accumulation of air bubbles
