Embodiment Construction

[0042] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0043] The structure of the disposable liquid-stopping slow-flow infusion set of the present embodiment is as follows:

[0044] Please combine Figure 1-4 It should be understood that the single-use liquid-stopping slow-flow infusion set in this embodiment includes a precision filter 1 , a conduit 2 , a dropping funnel 3 , an infusion conduit 4 and a liquid-stopping filter 5 connected in sequence.

[0045] The dripping funnel 3 includes an upper dripping funnel 31 and a lower dripping funnel 32. The upper part of the upper dripping funnel 31 communicates with the precision filter 1 through the conduit 2 (for the structure of the precision filter, please refer to the patent of Publication No. 103157154A). A liquid-stopping device is provided in the dripping funnel 32, and the liquid-stop...

Abstract

The invention discloses disposable liquid-stopping and flow-slowing infusion apparatus which comprises a dripping funnel and a liquid-stopping device arranged in the dripping funnel. The liquid-stopping device comprises a liquid-stopping membrane; when working, the liquid-stopping membrane is attached to the inner wall of the bottom of the dripping funnel, and the inner wall of the bottom of the dripping funnel is provided with at least one groove; the groove comprises an upper port and a lower port; when the liquid-stopping membrane is attached to the inner wall of the bottom of the dripping funnel, liquid medicine in the dripping funnel sequentially flows through the upper port and the lower port and then enters an infusion catheter; the bottom of the dripping funnel and a liquid-stopping filter are mutually communicated through the infusion catheter. The disposable liquid-stopping and flow-slowing infusion apparatus has the dual functions of preventing blood from flowing back and stopping liquid automatically.

Description

technical field [0001] The invention relates to a medical device, in particular to a one-time-use liquid-stopping slow-flow infusion set. Background technique [0002] At present, clinically, in the drip transfusion process for medical treatment of patients, drip infusion sets with flow controllers and liquid stop control devices are widely used. [0003] The invention with the application number of 201010573350.9 discloses a liquid stop control device for an infusion set. It at least includes a liquid-stopping part that can float in the dropping funnel; an anti-blocking structure is set between the liquid-stopping part and the liquid inlet part. The present invention adopts the above-mentioned structure, and by setting an anti-clogging structure between the liquid-stopping part and the liquid-inlet part, it effectively avoids the situation that the liquid-stopping part blocks the liquid-inlet part, resulting in the situation that the infusion cannot go down, and reduces th...
