Exhaust.
Please refer to Fig. 1 and Fig. 2, the working principle of the disposable nutrient input liquid device of the utility model embodiment are as follows:
When infusion starts, medical fluid is flowed into dropping funnel 3, is diverted in dropping funnel 3 by the infusion pipe portion 301 in dropping funnel 3 and fair current accumulates on drop
It struggles against 3 bottoms, this branching process greatly reduces the generation of air bubble, when medical fluid is accumulate in dropping funnel 3 close in infusion pipe portion 301
When end, medical fluid pressure itself makes it through gap air discharge duct 3011 and flows into infusion pipe portion 301, when the medical fluid is rigid by conduit 1
When into filter 4, start to be vented again by two exhaust passages 405 on filter 4, when medical fluid is accumulate to full of first
When chamber 403, due to hydraulic effect, it is vented automatically again by the exhaust passage 405 on filter 4, is truly realized medicine
Without " air bubble " in liquid, and be vented thoroughly, it is clean, will not when starting infusion or change bottle be infused again when due to generate " air
The problem of bubble ", keeps patient very safe in integrally infusion.Medical fluid stops liquid film piece 6 by filtering and filters and in second chamber
Inflow catheter 1 and transfusion needle 5 after being accumulated in 404, so that it may be infused to patient, after infusion, remaining medical fluid is filtered
Only the tension force effect of liquid film piece 6, which is shut off, realizes automatic liquid-stopping, avoids human vas blood back and " thrombus " occurs, be conducive to medical care
The clinical position of personnel alleviates the working strength and pressure of medical staff, reduces the medical treatment therefore caused between shield trouble and entangles
Confusingly, and nursing Risk is reduced, improves nursing quality.If being infused again, plugging another bottle of liquid medicine can continue to be infused, and own
Automatic exhaust, the process for filtering, stopping liquid are as when first bottle of infusion, and therefore, which has accomplished intelligence in infusion completely
Energyization exhaust, automatic liquid-stopping and safety filtering.It is protected from light if necessary, can add in the material and be protected from light agent.
The above content is the further description for combining specific embodiment to do the utility model, and it cannot be said that
The specific implementation of the utility model is only limited to these instructions.For the ordinary skill people of technical field belonging to the utility model
For member, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, all should be considered as
Belong to the protection scope of the utility model.
