Description
Technical field
A kind of automatic liquid-stopping transfusion apparatus is the utility model is related to, belongs to technical field of medical instruments.
Background technology
At present, the disposable transfusion device used on the market, all without the function of automatic liquid-stopping when transfusion terminates soon,
Terminate soon when ward or patient do not notice to infuse, in the case where not notifying nurse or doctor, worked as decoction
When not pulled up after all being dripped off by transfusion device and transfusion needle from patient body again, the situation of patient blood refluence can be caused
Occur, unnecessary injury is caused to patient.It is therefore desirable to a kind of disposable transfusion device with automatic liquid-stopping function ensures
Even if patient is when infusing completion because looking after inconsiderate the occurrence of will not also causing backflow of blood.
The content of the invention
The purpose of this utility model is：For above-mentioned the deficiencies in the prior art, there is provided one kind is simple in construction, need not see
Shield in real time monitoring infusion bottle in dose, infuse complete when pull up not in time transfusion needle will not also cause backflow of blood phenomenon send out
Raw automatic liquid-stopping transfusion apparatus.
The utility model is to realize above-mentioned purpose by following technical solution：
A kind of automatic liquid-stopping transfusion apparatus, it by bottle cork needle, woven hose, dropping funnel, flow regulator, liquid medicine filter and
Cylindrical taper joint is formed, it is characterised in that：One end of woven hose is socketed with bottle cork needle, and the other end connection of woven hose is connected to
Cylindrical taper joint, is provided with dropping funnel on the woven hose between bottle cork needle and cylindrical taper joint, dropping funnel and cylindrical taper joint it
Between be disposed with flow regulator and liquid medicine filter.
Described dropping funnel on dropping funnel by being covered, dropping funnel is trapped and formed with diaphragm, and dropping funnel sealing of trapping is socketed on dropping funnel in set,
The top that dropping funnel is trapped is provided with diaphragm, and dropping funnel is divided into two chambers up and down by the diaphragm, and upper chamber is dropping liquid chamber, cavity of resorption
Room is feed liquor chamber.
A circle annular ledge is provided with the outer surface that the dropping funnel is trapped.
Described diaphragm is made up of polyether sulfone materials.
B shapes projection is evenly equipped with the circumference of described bottle cork needle bottom.
The B shapes projection is made up of elastic rubber material, and raised at least 3.
Described flow regulator is made up of mounting seat and regulation roller, and mounting seat slip cap is on woven hose, installation
Regulation roller is provided with by bearing pin on seat, adjusting the provided circumferentially about of roller there are the gear teeth；Woven hose corresponding with flow regulator
On be provided with regulation tooth, regulation tooth is connected with gear teeth meshing.
The beneficial effect of the utility model compared with prior art is：
When in use, the B shapes projection set on its bottle cork needle can prevent transfusion device from existing to the automatic liquid-stopping transfusion apparatus
External force effect is lower to depart from infusion bottle, avoids generating a panic to patient and family members, its flow regulator is by the gear on regulation roller
Connection is engaged with the Saw blade set on woven hose, prevents from changing transfusion speed under the non-artificial state of flow regulator, makes patient
Feel at ease to infuse under the flow velocity set, it is not necessary to worry change in flow；During normal infusion, had in drip chamber room enough
More decoctions, and do not had the height of diaphragm, at the end of transfusion is fast, the highest liquid level of decoction is in dropper component in drip chamber room
Inside it is gradually reduced, because diaphragm uses sweat soldering to be fixed on the top that dropping funnel is trapped, its sealing property is excellent, and due to diaphragm
Pressure-resistant effect, prevent air enter feed liquor chamber, prevent decoction from continuing to flow downward, so as to realize automatic stopping infusion,
Solving patient can not notify nurse or doctor to pull out pin in time when nursing inconsiderate either other reasonses and causing transfusion to be completed
Head and cause patient blood flow back situation the problem of.

Embodiment
The automatic liquid-stopping transfusion apparatus is by bottle cork needle 1, woven hose 2, dropping funnel, 3 flow regulators 4, the and of liquid medicine filter 5
Cylindrical taper joint 6 is formed, and one end of woven hose 2 is socketed with bottle cork needle 1, and the other end connection of woven hose 2 is connected to outer cone
Joint 6, is provided with dropping funnel 3 on the woven hose 2 between bottle cork needle 1 and cylindrical taper joint 6, dropping funnel 3 and cylindrical taper joint 6 it
Between be disposed with flow regulator 4 and liquid medicine filter 5；Dropping funnel 3 by dropping funnel cover 8, dropping funnel trap 9 and diaphragm 10 form,
Dropping funnel 9 sealings of trapping are socketed on dropping funnel in set 8, dropping funnel trap 9 outer surface on be provided with a circle annular ledge 11, on dropping funnel
The lower surface of set 8 is located just in annular ledge 11, and annular ledge 11 forms a support force and with spacing to set 8 on dropping funnel
Effect, trap 8 top of dropping funnel are provided with diaphragm 10, and diaphragm 10 is made up of polyether sulfone materials, and diaphragm 10 divides dropping funnel 3 to be upper and lower
Two chambers, upper chamber are dropping liquid chamber, and lower chambers are feed liquor chamber, when the decoction in dropping funnel 3 did not had diaphragm 10, transfusion device
It can be normally carried out infusing, after decoction as little as diaphragm 10 times, because the diaphragm 10 of polyether sulfone material can prevent the stream of air
It is logical, cause the decoction of lower chambers can not flow, stop transfusion, the only liquid function at the end of realization transfusion is fast.
