Automatic liquid-stopping and transfusion system

Abstract

The invention provides an automatic liquid-stopping and transfusion system. The automatic liquid-stopping and transfusion system comprises a transfusion container and a transfusion device. Transfusion flexible pipes are connected to the upper portion and the lower portion of a dripping hopper of the transfusion device respectively, the transfusion container comprises a bottle opening and a bottle plug, a guiding pipe is arranged in the transfusion container, a longitudinal opened groove is formed in the guiding pipe, the upper end of the guiding pipe is closed, the lower end of the guiding pipe is connected with the bottle opening of the transfusion container, a floating ball is arranged in an inner cavity in the guiding pipe, a valve base is arranged on the bottle opening of the transfusion container, and the floating ball is matched with a valve opening of the valve base; a floating ball valve is arranged in the dripping hopper of the transfusion device, and after transfusion medicine liquid in the dripping hopper is completely delivered, the floating ball valve can enter inlets in the transfusion flexible pipes below the dripping hopper. According to the automatic liquid-stopping and transfusion system, two liquid-stopping valves are arranged up and down, the dual liquid-stopping effects are achieved, residual liquid of transfusion is automatically retained, the transfusion device still can retain part of liquid under the condition that artificial interference does not exist accordingly, it is stopped that air enters the human body after liquid is delivered, work of nurses is greatly reduced, and patient-hospital disputes are reduced.

Description

technical field [0001] The invention belongs to the technical field of lighting, and relates to an LED wick lamp, in particular to an LED spiral wick and an LED spiral wick lamp. Background technique [0002] The infusion system includes a liquid infusion set and an infusion bottle. The liquid infusion set is a common medical consumable. After aseptic treatment, a channel between the vein and the liquid medicine is established for intravenous infusion. Generally, it is composed of eight parts such as intravenous needle or injection needle, needle cap, infusion hose, liquid medicine filter, flow rate regulator, dropping funnel, bottle stopper piercer, and air filter. [0003] During the infusion process, it is very important for the safety of the infusion to eliminate the gas in the liquid medicine and prevent the phenomenon of blood return. If it is not handled properly, in case air enters the catheter at the lower part of the dropping funnel, unexpected blood return will o...

Problems solved by technology

The above-mentioned patents generally have the following deficiencies in practical applications: First, the seal between the floating body and the liquid outlet at the bottom of the dropping funnel or the liquid outlet at the bottom of the housing is sealed by contacting the sealing diaphragm on the plane, and the sealing film When there is a certain space inside the tablet and the floating body, air bubbles are likely to be generated when the infusion alternates; secondly, when the liquid is stopped by the plugging method, the accuracy of the seal between the floating body and the liquid outlet at the bottom of the dropping funnel is high, and the existing production The process is difficult to meet the requirements of complete sealing, resulting in low sealing reliability and low safety; third, when the liquid is stopped by the membrane sealing method, the sealing diaphragm must be designed to be thinner in order to effectively wrap the sealing outlet, making the practical Because the protruding end of the outlet part of the liquid medicine is easy to pierce the film, resulting in failure to seal
