Safe and convenient transfusion utensil

Abstract

The present invention provides a safe and convenient infusion set, which comprises a cork piercer, a drip hopper, a duct, an adjustor and an infusion needle. The infusion set is characterized in that a passage switcher is arranged between the cork piercer and the drip hopper, wherein, the upper end of the passage switcher is communicated with the cork piercer, and the lower end which can open or shut the drip hopper is communicated with the drip hopper. The passage switcher comprises a floating valve cavity, a core rod and a floating valve; wherein, the core rod provided with a throughhole isarranged on the internal lower end of the floating valve cavity; the floating valve is arranged over the throughhole of the core rod; the upper end of the floating valve cavity is communicated with the cork piercer; and the core rod passes through the lower end of the floating valve cavity to be communicated with the drip hopper. The present invention ensures that infusion set can realize automatic exhaust and reliably prevent the backflow of blood, and resolves the problem of too much residue, which all the prior blood backflow prevention techniques cannot resolve, and the infusion set has the advantages of feasible technique, low cost and simple operation. The infusion set can greatly increase infusion efficiency and improve the safety of infusion.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a safe and convenient infusion set. Background technique [0002] The existing infusion set is composed of a cork puncturer, catheter, drip funnel, dropper and liquid medicine filter. There are two problems that have not yet been really solved during use. One is that the exhaust is difficult, and it is cumbersome to use. The excess gas can only be discharged by inverting the dropping funnel or using other operating methods such as pinching the catheter. If the experience is insufficient and the operation is improper, the liquid and the gas in the dropping funnel will form a large continuous bubble after they enter the downcomer. Eliminating these air bubbles requires nursing staff to perform complex and time-consuming operations, which not only reduces nursing efficiency and increases labor intensity, but also wastes liquid medicine and is more likely to cause iatrogenic...

Problems solved by technology

[0003] For this reason, the Chinese patent application 200610146971.2 automatic exhaust self-destruct type infusion set and the Chinese patent application 200820126075.4 non-bubble infusion set have proposed a technical solution, which has its outstanding advancement in cost control and process implementation, but it only solves the problem. One of the above-mentioned problems, and as many as 19 Chinese patents or patent applications for anti-blood infusion tubes, such as Chinese patent application 200720093281.5, have the problem that they cannot be effectively realized in the process, and there is no suitable technical solution. The material is available for use, but also lacks the feasibility of actual operation. It simply prevents blood relapse in order to solve the problem of blood relapse, ignoring the needs of clinical application. In fact, not only does it not solve the problem, but it also complicates the operation method, and it does not have universal adaptability. and advanced
