Automatic exhausting and stopping infusion device with metal micro-flow controller

Abstract

This proposal discloses an automatic exhaust and liquid-stopping infusion device with a metal microflow controller, which includes a cork puncturer, an upper infusion tube, a dropper, a drip funnel, a lower infusion tube, a flow regulator, and an outer conical joint , capillary infusion tube, side wings, intravenous injection needle, is characterized in that: an exhaust pipe is inserted in the lower neck of the drip funnel, a liquid introduction hole connected to the drainage tube is arranged on the bottom support of the drip funnel, and the drainage tube The other end of the drop funnel is connected with the upper cover of the liquid stop liquid filter connected with the lower infusion tube; a metal plate with a micro-flow hole or a needle with a metal micro-flow tube is welded in the second convex tube seat. It can greatly improve the precision of the micro-flow hole, ensure that the infusion solution retained in the dropping funnel is continuously infused downward within several hours, and avoid blood clots at the intravenous injection needle due to flow interruption; and in the hemostasis At any time, the infusion solution retained in the dropping funnel can be exhausted immediately, so as to avoid the waste of infusion solution, or the reaction caused by the conflict between the two infusion solutions before and after.

Description

【Technical field】 [0001] The invention relates to a one-time use automatic air-stop liquid infusion set, especially suitable for anticoagulant infusion set after liquid stop. 【Background technique】 [0002] After stopping the liquid infusion set, if there is no nursing staff to deal with the infusion set in time, the needle tube of the intravenous injection needle will be blocked by blood clots. This is because after the liquid is stopped, the infusion at the intravenous injection needle is cut off, so that the venous blood is freed into the intravenous injection needle, and they will form blood clots after leaving the blood vessel, especially after they come into contact with substances such as salts in the infusion water, It also speeds up the formation of blood clots. And if these thrombus blocks enter the human body, within 48 hours, they are not ablated by CT observation, and if they cause myocardial infarction or cerebral infarction, it will cause sequelae or be life-...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the above-mentioned shortcomings of the automatic exhaust and stop liquid anticoagulation infusion set, the present invention proposes an automatic exhaust and stop liquid infusion set with a metal microflow controller, which can overcome the large deviation of precision when the micro flow hole is made of plastic materials And can not achieve the deficiency of the micro-flow effect, so that the infusion of the micro-flow can be continuously obtained at the intravenous injection needle within several hours after stopping the liquid, so during this period, it can prevent the blood from being coagulated in the needle tube of the above-mentioned intravenous injection needle block blocking phenomenon
