No-bubble infusion device

Abstract

The invention relates to the technical field of medical appliances and discloses a bubble-free transfusion set comprising a bottle cork puncture outfit, a conduit, a dropping funnel, a burette, a filter, and the like. The bubble-free transfusion set is characterized in that one burette is arranged in the dropping funnel, the lower end of the burette is closed, and the pipe wall of the burette is provided with a side liquid drain hole. The dropping funnel is extruded, and a liquid medicine, when being sucked, passes through the burette, flows out of the side hole of the burette, and is sprayed to the inner pipe wall of the dropping funnel to flow down; and after a liquid level of the liquid medicine is accumulated to reach certain height, the liquid medicine automatically drives the air in the conduit until the air is exhausted when flowing into a transfusion needle through a lower conduit. The liquid medicine flows down along the inner wall of the dropping funnel and is accumulated at the lower end of the dropping funnel when being sucked into the dropping funnel so as to prevent gravity impact from producing the mixing of gas and liquid, so no bubble is formed and the bubble-free performance is achieved. The bubble-free transfusion set solves the problems that the prior transfusion set is easy to form bubbles and has difficult air exhaust during the transfusion, has simple and cheap applying technology, does not increase the cost, abandons the fussy operation of the prior air exhaust mode to improve transfusion efficiency, and greatly improves the safety of the transfusion.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a bubble-free infusion set. technical background [0002] The existing infusion set is composed of a cork piercer, a catheter, a drip bucket, a drip tube and a liquid medicine filter. When in use, it is necessary to invert the drip bucket or use other cumbersome operation methods such as pinching the catheter to remove excess gas. If there is insufficient experience and improper operation, the liquid and the gas in the drip hopper will mix into the downcomer to form a large continuous bubble. Failure to find out due to negligence may cause air bubbles to cause harm or even fatal to the human body. Eliminating these air bubbles requires complicated and time-consuming operations by nursing staff, which not only reduces nursing efficiency and increases labor intensity, but also wastes liquid medicine and is more likely to cause iatrogenic infections. . The problem of exhausting d...

Problems solved by technology

Failure to find out due to negligence may cause air bubbles to cause harm to the human body or even be fatal. To remove these air bubbles requires nursing staff to perform complicated and time-consuming operations, which not only reduces nursing efficiency, increases labor intensity, but also wastes liquid medicine, and is more likely to cause iatrogenic infection

The problem of difficult exhaust has never found a universally adaptable, cheap and efficient treatment method since the infusion set came out for nearly a century
