Disposable self-stopping infusion apparatus

Abstract

The invention discloses a disposable self-stopping infusion apparatus, comprising a plug puncture outfit protecting jacket, a plug puncture outfit, an air filtering membrane, an air plug, an upper hose, a dropper, an emulsion cap, a self-stopping device, an upper dripping bucket, a lower dripping bucket, a pressure ball, a lower hose, a flow regulator, a liquor filter and an intravenous infusion needle. The disposable self-stopping infusion apparatus is characterized in that the self-stopping device comprises a limit shaft sleeve and a float valve and is arranged in the dripping buckets, the float valve consists of a float cover, a float shaft and a soft sucker, the limit shaft sleeve is embedded in the upper end opening part of the cavity in the lower drip chamber, the float shaft passes through the center of the limit shaft sleeve to be tightly matched with an inner sleeve of the float cover, the upper part of the soft sucker is embedded in the hollow part at the bottom of the float shaft and is limited by the limit shaft sleeve, the float cover and the soft sucker are connected by the float shaft and move up and down in the inner cavities of the upper and lower dripping buckets, and in infusion process, when liquor does not exist in a medicine bottle, and the liquor in the dripping buckets is too little, the float valve can automatically close the hoses to prevent air from entering into the lower hose to cause blood backflow, so that the waste of the liquor is reduced, the workload of medical personnel is reduced, and medical disputes due to medical negligence can be avoided.

Description

technical field [0001] The invention relates to a disposable medical device, in particular to a self-stop liquid transfusion device. Background technique [0002] Disposable infusion sets used clinically in clinical units of various domestic medical institutions are mainly composed of bottle stopper puncturer protective cover, bottle stopper puncturer, air filter, infusion hose, dropper, dropper, flow regulator, liquid medicine filter The product is composed of a device and an intravenous infusion needle. During the clinical use of this product, especially when the liquid medicine is about to run out, the family members of the patient are very nervous. Entering the lower hose under the drip funnel, in order to continue the infusion, the nursing staff can only exhaust the air by wrapping the lower hose around the fingers, which is very inconvenient to operate. At present, there are also self-stop liquid devices on the market, but in the clinical use of these products, the ef...
