Disposable infusion set with drop stop device

Abstract

The invention discloses a disposable infusion device with a liquid-drop-stopping hollow device. The disposable infusion device comprises a dropper, a drip chamber and a liquid-stopping device. The liquid-drop-stopping hollow device comprises a tee-joint device connected with a lower drip chamber, wherein a press cover is arranged on the tee-joint device. The liquid-drop-stopping hollow device further comprises a balloon pressurizing device arranged nearby the drip chamber, wherein the balloon pressurizing device is compressed to enable liquid medicine in a catheter to impact the liquid-stopping device, and the liquid-stopping device is separated from the drop-stopping face of the lower drip chamber. The disposable infusion device utilizes the liquid-drop-stopping hollow device to perform automatic liquid stopping through a liquid-stopping film and then utilizes the balloon pressurizing device to enable the inside liquid medicine to move upward and impact the liquid-stopping device, and the liquid-stopping device floats under the buoyancy effect to achieve normal infusion. When the liquid medicine is left only in the catheter, the drip chamber is communicated with the outside atmosphere by opening the press cover, and the liquid medicine in the catheter and the lower drip chamber is led into a catheter. Medicine waste is reduced, and meanwhile environmental pollution is avoided. The medication dose for a sick body is ensured. The disposable infusion device is compact in structure and quick and convenient to use.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable infusion set with a device for stopping liquid drops and emptying. 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 canno...
