Automatically exhausting self-destruction type infusion device

Abstract

The invention discloses a transfusion apparatus which has automatic air exhaustion and self destruction, and consists of a puncturing apparatus of a bottle stopper, a catheter and a dropping funnel, and the invention is characterized in that an air exhausting tube is arranged inside the dropping funnel, and the lower end of the air exhausting tube is communicated with a lower catheter, the upper end of the air exhausting tube is oblique, and when liquid medicine is injected into the dropping funnel, the extra air in the dropping funnel automatically exhausts through the air exhausting tube. Liquid medicine flows into the lower catheter through a transfusion orifice when the liquid surface is higher than the transfusion orifice of the air exhausting tube. The extra air in the dropping funnel exhausts before liquid medicine flows into the lower catheter, thus bubble is not formed and automatic air exhaustion is achieved. The residue liquid under the transfusion orifice in the dropping funnel can not be discharged, cleaned and reused, thus achieving the effect of self destruction.

Description

technical field [0001] The invention relates to the category of medical equipment, and is an automatic exhaust and self-destruct infusion set. Background technique [0002] Generally, the infusion set is composed of a cork puncturer, a drip funnel and a catheter. When using it, the drip funnel must be turned upside down to remove excess gas. If the experience is insufficient and the operation is improper, the liquid and the gas in the drip funnel will mix and enter the lower catheter to form air bubbles. Getting rid of these bubbles is not only troublesome but also a waste of liquid medicine. This kind of infusion set, which is originally a one-time use, is often reused to cause cross-infection. [0003] In view of the above reasons, the Chinese patent (patent number: ZL 032054599) proposes an anti-bubble infusion device, which is suitable for non-gravity infusion devices. At the beginning of operation, it is still necessary to artificially exhaust, and the exhaust method i...

[0003] In view of the above reasons, the Chinese patent (patent number: ZL 032054599) proposes an anti-bubble infusion device, which is suitable for non-gravity infusion devices. At the beginning of operation, it is still necessary to artificially exhaust, and the exhaust method is basically the same as that of the existing infusion set, and even more troublesome.
