Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of automatic liquid-stopping transfusion apparatus.
Background technique
At present in medical industry, when having an intravenous drip to patient's infusion, usually there are two types of methods: first is that making dropper in lower liquid out
Mouth excludes air in dropping funnel above, reapposes after being filled with dropping funnel half in dropping funnel and vertically bubble is avoided to generate；It is another
Method is to close flow regulator, pinches after pressing dropping funnel that it is made to suck medical fluid to about 1/2 to 2/3 place of dropping funnel, slowly opens flow
Adjuster also can avoid bubble and generate.But both methods relatively complicated complexity in operation, it is slightly improper such as to operate,
Cause bubble to enter perfusion tube then and additionally to release a certain amount of medical fluid to go to exclude bubble, both be caused not to medical staff in this way
Just, the waste of medical fluid is also resulted in, while at the end of infusion such as patient has found not in time, will lead to perfusion tube blood back, making disease
People generates panic.
Chinese patent CN201320129476.6 discloses a kind of automatic liquid-stopping transfusion apparatus, including successively penetrating through inserting for connection
Bottle needle, dropping funnel, hose, liquid medicine filter and intravenous infusion needle, the dropping funnel, which is equipped with, hinders hose as the medical fluid page declines
The blocking device of plug；Utility model has the advantages that after infusion can automatic liquid-stopping, effectively delay blood back, mitigate
The nursery work intensity of medical worker and the lines of strain and fear mood of patient.
Chinese patent CN201210036854.6 discloses a kind of disposable from limiting from liquid infusion apparatus, including bottle is stopped
Fill in puncture outfit protective case, bottle plug puncture unit, air-filtering membrane, air lock, top hose, dropping funnel lid, latex cap, from limiting device,
From only liquid device, upper dropping funnel, lower dropping funnel, pressurize bead, bottom hose, flow regulator, liquid medicine filter and intravenous infusion needle,
It is characterized in that: being made of from limiting device the exhaust passage that air lock, air-filtering membrane and dropping funnel cover, include from only liquid device
Limit shaft sleeve and only liquid valve, only liquid valve is made of floating head, floating axle and soft sucker, is placed in dropping funnel from only liquid device, limit shaft
Set is embedded in lower dropping funnel inner cavity upper end oral area, and floating axle is fitted close by limit shaft sleeve center and floating head inner sleeve, in soft sucker top
It embedded in floating axle bottom recessed portion, and is limited by limit shaft sleeve, floating head is connected with soft sucker by floating axle, in upper dropping funnel and lower dropping funnel
Inner cavity moves up and down, and bottle plug puncture unit can be inserted into fast automatic lower liquid after large transfusion bottle plug, control liquid level height in dropping funnel by it
Air in degree, automatic exclusion dropping funnel；When very few without medical fluid in medical fluid, dropping funnel in medicine bottle in infusion process, only liquid valve energy automatic sealing package
Stopped pipe road causes blood back after preventing air from entering in bottom hose, had not only reduced the waste of medical fluid in this way, but also reduce medical staff
Workload, and be avoided that malpractice occur caused by medical tangle.
Although above-mentioned two patent can avoid the generation of blood return phenomenon at the end of infusion while eliminating bubble, tying
It is complex on structure, while blood back can only be slowed down, the generation of blood return phenomenon cannot be but prevented completely.
Therefore be badly in need of it is a kind of can effectively avoid bubble from entering perfusion tube, while can effectively prevent blood back at the end of infusion
Automatic liquid-stopping transfusion apparatus.
