Description
Technical field
This utility model relates to a kind of medical devices, particularly a kind of puncture outfit for bottle stopper of infusion apparatus.
Background technology
Transfusion device is the widely used medical devices for patient fluid infusion in medical treatment, health industry.Existing transfusion device, when for patient fluid infusion, must have entourage's moment to observe the liquid level of infusion bottle inner liquid medicine, and changes infusion bottle opportunity in the best replacing.If particularly medicinal liquid is colourless transparent liquid, need entourage to observe for a long time, cause certain trouble to entourage.Sometimes because of the fatigue or busy of entourage, and miss the opportunity changing infusion bottle, cause air to enter in tube for transfusion, cause situations such as " blood backs " to occur.
In order to solve the problem, patent No. ZL 201320594862.2 discloses a kind of transfusion device, arranges elasticity ball float in the inner infusion channel of transfusion device perforator, reaches automatic liquid-stopping object by ball float by medicinal liquid buoyancy blocking infusion channel.But the method affects comparatively large by medicine liquid ingredient and degree of purity, slightly impurity, granule, ball float just cannot be identical with tube for transfusion, and infusion bottle also cannot detent plug infusion channel stressed to rock under state, cannot realize automatic liquid-stopping, there is potential safety hazard.This not only adds nursing staff's extra work amount, and cause unnecessary trouble to patient.
Summary of the invention
For the deficiency that prior art exists, this utility model provides a kind of puncture outfit for bottle stopper of infusion apparatus, by the improvement to its structure, realizes the function of automatic liquid-stopping, to stop potential safety hazard, is convenient to nursing staff and changes infusion bottle in the best opportunity.
This utility model solves the technical scheme that its technical problem adopts:
A kind of puncture outfit for bottle stopper of infusion apparatus, comprise puncture tube, puncture tube upper end is provided with needle point, and in the middle part of puncture tube, lateral body is provided with air inlet, is provided with inlet channel and infusion channel in puncture tube, and inlet channel connects air inlet pipe through air inlet and is connected with air filter; Needle point direction is from the close-by examples to those far off provided with successively and is positioned at the first shim below air inlet, the second shim and for conducting or the barrier sheet of closing infusion channel relatively in puncture tube, first shim and the second shim outer ledge are fixedly connected with along the inner surface of puncture tube sidewall with it respectively, also be provided with the spring running through the second shim in puncture tube, both ends of the spring portion is fixedly connected with barrier sheet with the first shim respectively; Described first shim, the second shim offer respectively the first through hole, the second through hole.
Concrete, described barrier sheet offers third through-hole, and after spring contraction, the second through hole is positioned at the contact surface of barrier sheet and the second shim, and the second through hole and third through-hole zero lap.
Concrete, described barrier sheet does not offer through hole, and after spring contraction, the second through hole is positioned at the contact surface of barrier sheet and the second shim.
When there being medicinal liquid dirty in infusion bottle, medicinal liquid flows through the first shim and the second shim, due to the first shim and the second shim offering through hole respectively, medicinal liquid flows through flow velocity herein and becomes large, thus impacts barrier sheet, spring is stretched, barrier sheet moves down, and infusion channel is in conducting state; When infusion bottle herb liquid flows to end, spring shrinks automatically, and infusion channel is in closed condition, stops air to enter in tube for transfusion.
Compared with prior art, the beneficial effect produced is puncture outfit for bottle stopper of infusion apparatus of the present utility model:
1, this utility model structure is simple, by spring elongation or contraction, drives barrier sheet motion, reach the method for conducting or occluding infusion passage, realize automatic liquid-stopping function, be convenient to nursing staff and change transfusion device in the best opportunity, the situations such as " blood backs " that effectively prevent occurs.
2, this utility model is by the impact of medicinal liquid degree of purity, even if infusion bottle also can detent plug infusion channel stressed to rock under state, realizes automatic liquid-stopping, has effectively stopped potential safety hazard.
