Disposable float type automatic liquid stop duplex-discharge infusion apparatus

Abstract

The invention discloses a disposable float type automatic liquid stop duplex-discharge infusion apparatus. The disposable float type automatic liquid stop duplex-discharge infusion apparatus comprises a liquid inlet port, a dropper, a float valve, an infusion tube, a liquid medicine filter, a dripping speed regulator, a liquid outlet port, a closed air guide mechanism, a gallbladder-simulated bottle rinsing dripper and a direction change pump arranged on the infusion tube. The disposable float type automatic liquid stop duplex-discharge infusion apparatus has the advantages that firstly, automatic liquid stop can be realized, and troubles, waste and possible occupational infections caused by liquid supplement after an infusion needle is separated for liquid discharge and air discharge can be avoided; secondly, precious residual liquid in an infusion bottle and the infusion tube can be discharged downwards to be infused into a human body, so that waste is prevented while curative effects can be guaranteed; thirdly, bubbles generated in the infusion tube can be intercepted and collected to be discharged upwards to the float valve and a cavity of the dripper; fourthly, blood return, liquid passage blockage caused by blood coagulation and possible blood exposure accidents can be avoided; fifthly, drip infusion can be accelerated, and pumping the air in the infusion tube into the human body accidentally due to misoperation can be avoided. The disposable float type automatic liquid stop duplex-discharge infusion apparatus is a multifunctional infusion apparatus and is applicable to massive long-time drip infusion for clinical patients, especially critical patients, in the dead of winter.

Description

technical field [0001] The invention relates to a disposable automatic stop-flow liquid-residue-preventing infusion set for medical use, in particular to a disposable buoy-type automatic stop-liquid and double-row infusion set. Background technique [0002] On March 12, 2014, the State Intellectual Property Office announced a "disposable automatic stop-flow anti-liquid residue infusion set" (invention patent application number: 201310616062.0; issue number: 2014030600274840), which is a buoy-type automatic stop Anti-liquid residual infusion set. Its defect is: 1. referring to accompanying drawing 15,21,22 of specification sheet, owing to be provided with check valve 92 on the liquid inlet of the pressurized bag 35 of manual pressurized pump 93, in mid-winter season, when icy liquid enters after heating ward , the gas dissolved in the gap between water molecules expands when heated (especially the liquid in the infusion tube heats up faster than the liquid in the infusion bo...

Problems solved by technology

Its defect is: 1. referring to accompanying drawing 15,21,22 of specification sheet, owing to be provided with check valve 92 on the liquid inlet of the pressurized bag 35 of manual pressurized pump 93, in mid-winter season, when icy liquid enters after heating ward , the gas dissolved in the gap between water molecules expands when heated (especially the liquid in the infusion tube heats up faster than the liquid in the infusion bottle) and precipitates to form bubbles attached to the inner wall of the infusion tube (this application is referred to as "endogenous bubbles in the infusion tube" for short) ) is difficult to discharge upwards; when a critically ill patient receives a large amount of infusion, and the air bubbles in the infusion tube accumulate for a long time, the infusion needle must be separated for drainage, exhaust and refilling, which is not only troublesome, but also causes waste, Interface pollution and possible occupational infection, so it is not suitable for drip infusion of critically ill patients in the middle of winter; especially when the impact force of the pressurized rapid infusion increases, the air bubbles may enter the human body, and there is even a risk of excessive extrusion of the pressurized bag. The danger of accidentally pumping the gas in the infusion tube into the human body; in addition, it cannot intercept and collect the endogenous air bubbles from the infusion tube; ② if Figure 4 , 6 The manual booster pump shown not only cannot intercept and collect the endogenous air bubbles from the infusion tube, but also has to open and close its inlet and outlet ports alternately when pressurizing the infusion quickly and forcing in the residual liquid, and its operation is more troublesome; Since there is no check valve on the liquid outlet of the pressurized bag, especially patients in single wards who carry a drip infusion bottle in the bathroom slip or fall or faint (such as: hypoglycemia, orthostatic hypotension, cough, urination, pain, mental stimulation syncope) , haemorrhage, cerebral sudden onset, epilepsy, brain tumor, constipation-induced myocardial infarction, etc.) without timely detection and timely treatment often lead to blood exposure (refers to blood backflow into the infusion set, infusion bottle) accidents, or broken in the infusion bottle It will cause blood leakage, which is very dangerous!
