Description
Technical field
The invention belongs to single use medical instruments field, particularly relate to a kind of transfusion device aerofluxus in delivery device
Device.
Background technology
The transfusion device of Clinical practice is typically main by bottle plug puncture unit, dropping funnel, flexible pipe, flow regulator, joint group now
Become, when carrying out pharmaceutical liquid perfusion, need to be inverted dropping funnel, and extrude dropping funnel, make liquid rise from bottom to top, arrive certain high
When spending, by dropping funnel along putting, the air in dropping funnel could be discharged.Misoperation, in dropping funnel, liquid and gas are mixed into flexible pipe,
Can form bubble, cause potential safety hazard, as improper in controlled, in causing dropping funnel, liquid level is too high or too low, and dropping funnel liquid level is too high not
Being beneficial to the observation of number of infusion drops, dropping funnel liquid level is too low, is likely to result in liquid, gas mixture, enters flexible pipe, causes potential safety hazard.

Molecular material manufactures, and transfusion device automatic exhaust steam valve base is provided with aerofluxus, catheter, and described aerofluxus, catheter are distributed on transfusion
On the base of device automatic exhaust steam valve, aerofluxus, catheter and dropping funnel upper end liquid outlet the most on the same axis, the automatic aerofluxus of transfusion device
Valve is arranged in dropping funnel, and automatic exhaust steam valve is very close to each other with dropping funnel contact surface.Transfusion device automatic exhaust steam valve base is provided with fixing
Aerofluxus, catheter, every aerofluxus, catheter are provided with the intake chute of 1 or 2 or 3 aerofluxus.Due in base in this patent
The space of portion's part exists big, easily forms bubble in chassis interior part for the first time and have the hidden danger of entrance human body during aerofluxus.
Principle is that the liquid inlet from infusion unit titrimeter top goes out liquid, flows through automatic exhaust steam valve, by the row on aerofluxus, catheter
Gas, intake chute enter chassis interior part, and the liquid outlet eventually flowing to dropping funnel lower end enters human body, due to chassis interior part
Space is bigger, and liquid is when dirty, and the liquid flowed out from aerofluxus, intake chute all has a flowing to each method, but due to
The liquid outlet of distance infusion unit titrimeter is closer, and then first flows to liquid outlet, chassis interior part cavity underfill, thus causes
Bubble deposits.
