During use, because bar in switch is combined on liquid stopping clamp seat releasedly to lock the position of liquid stopping clamp switch on liquid stopping clamp seat, therefore can singlehanded input pipe be put in opening exactly, and then bar and liquid stopping clamp seat in switch are threaded off, thus liquid stopping clamp switch closes described opening, therefore simple to operate.
In a preferred embodiment of the invention, make after in switch, bar and liquid stopping clamp seat are threaded off, to make to make liquid stopping clamp switch closed described opening automatically, to make operation more simple by extension spring.
In a preferred embodiment of the invention, be by bar in rotating switch, bar and liquid stopping clamp seat in switch are threaded off, in switch, bar has the outer end of exposed parts, the outer end of bar in hand switch, just can bar in rotating switch, therefore easy to operate.
Accompanying drawing explanation
Fig. 1 is the main pseudosection of infusion pump liquid stopping clamp.
Detailed description of the invention
As shown in Figure 1, the liquid stopping clamp of (medical) infusion pump comprises liquid stopping clamp seat 1, bar 4 in liquid stopping clamp switch 2 and switch.Liquid stopping clamp seat 1 has groove 9, and groove 9 runs through the both sides of liquid stopping clamp seat 1, and groove 9 provides the opening just passed from this groove 9 for tube for transfusion.Liquid stopping clamp switch 2 inserts groove 9, is exposed in liquid stopping clamp seat 1 outside its head 91, the position that its head 91 is stirred for hands, and liquid stopping clamp switch 2 is fixed on liquid stopping clamp seat 1 by the switch shaft 8 being arranged in groove 9, and liquid stopping clamp switch 2 can rotate around switch shaft 8.The afterbody 92 of liquid stopping clamp switch 8 and head 91 are positioned at the two opposite sides of switch shaft 8, afterbody 92 is connected by the outer lug 5 (being such as screw) in extension spring 6 and liquid stopping clamp seat 1, extension spring 6 applies pulling force on afterbody 92, to produce moment on liquid stopping clamp switch 2, liquid stopping clamp switch 2 is kept to turn to the position closing described opening.
In the position shown in the figure 1, the opening passed for tube for transfusion is opened, if liquid stopping clamp switch 2 turns left, will close opening, to clamp tube for transfusion.
Continue with reference to Fig. 1, liquid stopping clamp switch 2 has inner chamber 21, has bar 4 in switch in inner chamber 21, and in switch, bar 4 is fixed on only on liquid switch 2 by being arranged in inner chamber 21 bar axle 3, and can rotate around interior bar axle 3.In switch bar 4 head 41 outside be exposed at outside liquid stopping clamp switch 2, can stir for hands.In switch, the afterbody 42 of bar 4 contacts with the stage clip 7 of liquid stopping clamp switch 2 inner chamber, the power that stage clip 7 acts on the afterbody 42 of bar 4 in switch forces bar 4 in switch to rotate (or having this trend) clockwise, leans against on the inwall of inner chamber 21 to make bar 4 in switch.In switch, the afterbody 42 of bar 4 has buckle portion 420, corresponding buckle portion 420, has buckle portion 90 in the groove 9 of liquid stopping clamp seat 1, and buckle portion 420 and buckle portion 90 fasten releasedly.Stage clip 7 can keep buckle portion 420 and buckle portion 90 to be interlocked.
During use, in state as shown in Figure 1, because liquid stopping clamp switch 2 is connected by interior bar axle 8 with liquid stopping clamp seat 1, and bar 4 and liquid stopping clamp seat 1 fasten inside the Pass card, even if so achieve a pulling force of extension spring 6 applying, this pulling force is owing to offsetting the resistance of liquid stopping clamp switch 2 at fastening place, and liquid stopping clamp switch 2 keeps open state with liquid stopping clamp seat 1 all the time.Thus tube for transfusion can be put into easily a rational position.Now press the head 41 of the interior bar 4 that liquid stopping clamp switch 2 upper end is exposed again, then compression press spring 7, make interior bar 4 afterbody leave button bit in liquid stopping clamp seat 1.Now, liquid stopping clamp switch 2 just by the pulling force that the extension spring 6 be connected with screw 5 produces, gets back to initial position, and the opening formed with liquid stopping clamp seat 1 is closed, thus clamping tube for transfusion.
To release tube for transfusion, then stir liquid stopping clamp switch 2 downwards, drive bar 4 in switch to move downward together.When liquid stopping clamp switch 2 move to buckle portion 90 phase in the groove 9 of liquid stopping clamp seat 1 by time, interior bar 4 is because the elastic force of stage clip 7, closed position is slipped into along liquid stopping clamp seat 1 inwall, because fasten, even if so achieve a pulling force of extension spring 6 applying, liquid stopping clamp switch 2 keeps open state with liquid stopping clamp seat 1 all the time.
In sum, namely achieve the former operation needing both hands to complete of infusion pump liquid stopping clamp mechanism, being reduced to one hand can implement.Greatly reduce tube for transfusion and settle required time.
