Description
Technical field
The invention belongs to medical instruments, can be widely applied to the infusion needs of medical department, make not influencing patient
With while effectively reduce medical staff labor intensity.
Background technology
At present the application range of medical procedure medium sized vein infusion it is wider, annual usage quantity is huge, frequency of use compared with
Height, this makes the labor intensity for being operated in status of medical staff high；Simultaneously as infusion apparatus used at present is using process
In easy to produce bubble and threaten patient vitals, therefore, in infusion process either medical staff or patient height essence
It is refreshing nervous, to exacerbate working strength.In general, the primary infusion quantity of most of out-patients is all at two bottles or more, it is big absolutely
The average daily amount of infusion of partial inpatient is more.
Double modeling needle automatic connection infusion apparatuses of the present invention can access the defeated of the first and second two bottles (bag) not no incompatibility simultaneously
Liquid drug pulls gating switch bar to ensure patient's first defeated first bottle (bag) liquid using the float of liquid buoyancy effect；When first bottle
After use, float pushes gating switch bar and second bottle (bag) liquid is defeated by patient automatically (bag) drug；Installation is designed in dropping funnel
Transparent liquid gas barrier film ensure that no bubble enters patient's body.The intervention of medical staff is not necessarily to during infusion, all processes are automatic
It completes, largely improves the efficiency of medical staff, eliminate misgivings and worry during patient fluid infusion.
Invention content
The object of the present invention is to provide a kind of double modeling needle automatic connection infusion apparatuses, improve the efficiency of infusion work, reduce doctor
The labor intensity of shield personnel and the mental burden for reducing patient, can effectively improve medical services efficiency.
Technical solution of the invention is as follows：
A kind of double modeling needle automatic connection infusion apparatuses, including connection infusion bottle (bag) with blow vent, connection infusion bottle
The second modeling needle with blow vent of (bag), upper coyote hole, mesothecium, lower coyote hole, float, gating switch bar, upper sealing ring, lower sealing
Circle, liquid level hook, adherent of anti-float, diplopore blow vent, dropping funnel gas barrier film；First modeling needle with blow vent is connected to upper coyote hole,
Second modeling needle with blow vent is connected to lower coyote hole.Upper coyote hole and lower coyote hole are isolated by mesothecium.Upper coyote hole and lower coyote hole are all set
Inclined-plane ease gas top structure is set, inclined-plane ease gas top structure can drive the gas in coyote hole and be excluded by diplopore blow vent；Drop
Bucket；Dropping funnel transparent liquid gas barrier film；Flow control valve and transfusion needle.Upper coyote hole and lower coyote hole are all communicated to diplopore blow vent, band ventilation
The first modeling needle of mouth, a blow vent one cavity of composition of upper coyote hole and diplopore blow vent, second modeling needle, lower coyote hole with blow vent
A cavity is constituted with another blow vent of diplopore blow vent.The gating switch coordinated by mesothecium between the two cavities
Bar is connected to.
Float lower end has liquid level hook, liquid level hook to pull gating switch bar；Gating switch bar is equipped with upper-lower seal circle, choosing
The liquid that the lower seal of logical switch lever lower end seals up lower coyote hole enters mesothecium, is placed in the upper close of gating switch bar upper end
Seal depressurization acts on, and the liquid of upper coyote hole enters mesothecium；
The upper sealing ring of gating switch bar upper end plays sealing function, and the remaining liquid for sealing up coyote hole enters Chinese medicine
Room, while the lower seal depressurization effect of gating switch bar lower end, the liquid of lower coyote hole enter mesothecium；
The liquid of mesothecium supplies patient by the dropping funnel transparent liquid gas barrier film that dropping funnel and dropping funnel export.Transparent liquid gas barrier film ensures
Supply the presence of bubble-free in the liquid of patient.
When the first and second two modeling needles are inserted into the first and second two bottles of (bag) drugs respectively, the liquid in two bottles (bag) is under gravity
Separately flow into it is respective up and down coyote hole, due at the top of coyote hole inclined-plane escape gas top structure, drive the gas in coyote hole pass through it is double
Hole blow vent excludes, it is ensured that the not presence of gas other than liquid in coyote hole；When the float with constant weight is in liquid
Float downward is acted on, after floating reach a certain height, the liquid level hook of float lower end pulls gating switch bar, is placed in gating and opens
The lower seal for closing bar lower end plays sealing function, and the liquid for sealing up lower coyote hole enters mesothecium, meanwhile, it is placed in gating and opens
The upper sealing ring depressurization effect of bar upper end is closed, the liquid of upper coyote hole enters mesothecium；The liquid of mesothecium by dropping funnel and
The transparent liquid gas barrier film of dropping funnel outlet supplies patient.Transparent liquid gas barrier film ensure supply patient liquid in bubble-free presence.
When the liquid of upper coyote hole is gradually finished, and the liquid level of remaining liquid is not enough to maintain the floating of float, float drives
After liquid level links up with downlink certain altitude, the float with constant weight, which is pressed on gating switch bar, forces gating switch bar to move down.
The upper sealing ring for being placed in gating switch bar upper end plays sealing function, and the remaining liquid for sealing up coyote hole enters mesothecium,
Meanwhile it being placed in the lower seal depressurization effect of gating switch bar lower end, the liquid of lower coyote hole enters mesothecium；Mesothecium
Liquid pass through dropping funnel and dropping funnel outlet transparent liquid gas barrier film supply patient.Transparent liquid gas barrier film ensure supply patient liquid in nothing
The presence of bubble.
It is additionally provided with adherent of anti-float on float, adherent phenomenon is caused when float being avoided to float up and down.
Dropping funnel interconnecting piece can also coordinate dropping funnel transparent liquid gas barrier film, flow control valve, adjusting control that can be more convenient
Infusion.
Structure of the invention design is simple and convenient to operate, use reliability is higher.
