To achieve these goals, this utility model be employed technical scheme comprise that：
A kind of multichannel adapter, including housing, described housing is provided with an out splice going splice and at least two input adapters,
Each input adapter and out splice going splice are interconnected and form multichannel inner chamber, are provided with thin film switch and for beating in described input adapter
Open the driving means of thin film switch.
Preferably, described driving means include valve rod and back-moving spring, and described valve rod is movably arranged on by back-moving spring
In the cavity of input adapter, the front end of described valve rod is provided with trigger head corresponding with input adapter port, the tail end of described valve rod
Extend to thin film switch.
Preferably, the tail end-side wall of described valve rod is provided with screw thread.
Preferably, described thin film switch includes two panels thin film corresponding with valve rod tail end, and described two panels thin film setting is left
Right symmetrical and bonded to each other.
Preferably, described input adapter and out splice going splice are equipped with block.
The beneficial effects of the utility model：Multichannel adapter of the present utility model passes through to arrange thin film in input adapter
Switch and the driving means for opening thin film switch, if desired for during transfusion, syringe are inserted input adapter, when syringe
When joint touches driving means, driving means triggering open thin film switch so that input adapter and out splice going splice turn on into
Row transfusion, without manual operation valve element, when not using, thin film switch is in closure state, the operation principle phase infused with gas transmission
With, wherein thin film switch have one-way conduction effect, it is to avoid transfusion or gas transmission occur adverse current, achievable multichannel infuse simultaneously or
Gas transmission, structure is practical reliable, and operation is easier convenient.
Brief description
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.
Fig. 1 is the perspective view of embodiment one in this utility model；
Fig. 2 is the cross-sectional view of embodiment one in this utility model；
Fig. 3 is the cross-sectional view of embodiment two in this utility model；
Fig. 4 is the cross-sectional view of embodiment three in this utility model.
Specific embodiment
A kind of multichannel adapter that this utility model provides, including housing 1, this housing 1 is provided with an out splice going splice 12
With at least two input adapters 11, each input adapter 11 and out splice going splice 12 are interconnected formation multichannel inner chamber, connect in input
It is provided with thin film switch 2 and the driving means 3 for opening thin film switch 2, out splice going splice 12 and input adapter 11 can in 11
The medical devices such as the conventional syringe of coupling, transfusion device, gas transmission joint, are capable of multi-channel synchronous transfusion or gas transmission.
Wherein, driving means 3 include valve rod 31 and back-moving spring 32, and valve rod 31 is movably arranged on defeated by back-moving spring 32
Enter in the cavity of joint 11, specifically, be provided with the draw-in groove for clamping back-moving spring 32 in cavity, back-moving spring 32 is enclosed within valve
On bar 31, the front end of valve rod 31 is provided with trigger head 311 corresponding with input adapter 11 port, and the tail end of valve rod 31 extends to thin film
Switch 2.For example, it is desired to during transfusion, syringe be inserted input adapter 11, when the joint of syringe touches trigger head 311,
Valve rod 31 advances into cavity, so that valve rod 31 tail end pushes thin film switch 2 open, realizes input adapter 11 and out splice going splice 12
Conducting, transfusion liquid is in out splice going splice 12 output the pure man body.When pulling out syringe, under the elastic force of back-moving spring 32 acts on
Valve rod 31 is reset to origin-location, and thin film switch 2 re-closes.
Above-mentioned thin film switch 2 includes two panels thin film corresponding with valve rod 31 tail end, and the setting of two panels thin film is symmetrical simultaneously
Bonded to each other, diaphragm seal height, it can be ensured that occurring fitting closely between two panels thin film during negative pressure, has one-way conduction and makees
With, it is to avoid the refluence of liquid.Further, the tail end-side wall of valve rod 31 is threaded 312, the setting of screw thread 312 is favourable
In preferably strutting two thin film, but it is not limited to using screw thread 312 structure it is also possible to phase is realized by the raised structure of setting
Same effect.
