Description
Technical field
This utility model relates to transfusion device, a kind of pressurisable transfusion device.
Background technology
Disposable transfusion device be mainly used in venous transfusion through aseptic process, set up passage between vein and medicinal liquid
Common disposable medical treatment consumptive materials.Existing transfusion device is under atmospheric pressure effect, and infusion bottle inner liquid medicine is along transfusion pipe flow
Entering dropping funnel, when dropping funnel water column pressure is more than venous pressure, the liquid runs down flexible pipe in bottle flows into vein, i.e. medicinal liquid can only be at nature
Inject under pressure status in human body, it is impossible to realize pressurization fast injection, be not suitable for the venous transfusion that transfusion speed is required.
Utility model content
In order to solve the problem that prior art exists, the easy-operating pressurisable transfusion of one that this utility model provides
Device, by increasing injection pressure to improve transfusion speed.
To achieve these goals, this utility model be the technical scheme is that
A kind of pressurisable transfusion device, including transfusion body, the front end of described transfusion body is provided with injection needle, its tail end
Being provided with vein puncture head, described transfusion body is provided with dropping funnel and flow rate regulating valve, the tail end of described transfusion body be additionally provided with into
Trachea, one end of described air inlet pipe connects with transfusion body, and the other end is provided with and mates, with syringe nipple, the inlet suction port being connected,
It is provided with filter in described inlet suction port.
Preferably, described air inlet pipe is provided with valve switch.
Preferably, described inlet suction port is provided with block, and described block and inlet suction port are integral type attachment structure.
Preferably, described inlet suction port is female cone locked joints.
Preferably, the tail end of described air inlet pipe is provided with three way cock, and the main road two-port of described three way cock connects respectively
Vein puncture head and transfusion body, the bypass ports of described three way cock connects air inlet pipe.
Preferably, described dropping funnel is provided with liquid medicine injection loophole, and described liquid medicine injection loophole is provided with chock plug.
The beneficial effects of the utility model: by arranging air inlet pipe, at the air inlet of air inlet pipe at the tail end of transfusion body
It is provided with and mates, with syringe nipple, the inlet suction port being connected, when needing pressure-increasing injection, syringe is connected with inlet suction port, passes through
Syringe, to carrying out gas transmission supercharging in transfusion device, realizes the raising of injection speed by supercharging, and injector operations is convenient and swift, can
According to the needs of patient injection, coordinate flow rate regulating valve that injection speed is adjusted, practical reliable.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further.
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is the structural representation that in this utility model, gas transmission supercharging uses state.
Detailed description of the invention
Seeing Fig. 1, the pressurisable transfusion device of one of the present utility model, including transfusion body 1, the front end of transfusion body 1
Being provided with injection needle 6, the tail end of transfusion body 1 is provided with vein puncture head 2 and air inlet pipe 3, is provided with dropping funnel 4 on transfusion body 1
With flow rate regulating valve 5, one end of described air inlet pipe 3 connects with transfusion body 1, and the other end is provided with and mates with syringe 8 nipple even
The inlet suction port 31 connect, is provided with filter in inlet suction port 31, the structure of the not shown filter of accompanying drawing.This transfusion device is applicable to
Packed or bottled transfusion.
During normal infusion, the valve switch 33 in air inlet pipe 3 is normally opened, and air inlet pipe 3 is in natural inflow state, pressure of infusing
For natural atmosphere pressure.See Fig. 2, when needing pressure-increasing injection, syringe 8 is connected with inlet suction port 31, right by syringe 8
Carry out gas transmission supercharging in transfusion device, increase the pressure in infusion bottle 9 with this, it is achieved the raising of injection speed.After gas transmission completes
Close valve switch 33, thus be avoided that gas backflow.
In embodiment, inlet suction port 31 is female cone locked joints, is connected with the standard outer cone joint of syringe 8, when
When the nipple of syringe 8 inserts in inlet suction port 31, the female cone sidewall of inlet suction port 31 coordinates with nipple and reaches fastening effect.
Being provided with block 32 on inlet suction port 31, this block 32 is integral type attachment structure with inlet suction port 31, and block 32 is conducive to protecting
The clean hygiene of card inlet suction port 31, uses more convenient.
In embodiment, the tail end in air inlet pipe 3 is provided with three way cock 7, and the main road two-port of three way cock 7 connects defeated respectively
Liquid puncturing head 2 and transfusion body 1, the bypass ports of three way cock 7 connects air inlet pipe 3, and this spline structure is more firmly practical.
It addition, be provided with liquid medicine injection loophole on dropping funnel 4, this liquid medicine injection loophole is provided with chock plug.
The above, preferred embodiment the most of the present utility model, this utility model is not limited to above-mentioned enforcement
The structure of mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to guarantor of the present utility model
Protect scope.
