Description
Technical field
The invention relates to a kind of teaching syringe, particularly relates to one and can select not discharged from injection pin hole by liquid, it is also possible to the teaching that simulation liquid is discharged simulation syringe.
Background technology
In medical teaching process, student, when practising the operant skills such as puncture, injection, suction, first has to judge darting station, the degree of depth, in order to avoid patient causes unnecessary damage.The power devices such as a number of sensor, circuit board often it are equipped with inside the analogue model used in hands-on, in addition current used material can not live through puncture repeatedly, otherwise will leak, if user does not note will result in short circuit phenomenon, produce certain security hidden trouble.For this, model designer's also multipair circuit, sensor carry out the adjustment of position so that in a model away from the position of leakage.But the still unescapable needs having contact with liquid.It is badly in need of a kind of analog simulation syringe that can be supporting with teaching mode, it is possible to the process of realistic simulation injecting fluid, can not inject liquid into again in model；Meanwhile, if needing to inject liquid and just can playing when really simulating, it is also possible to inject liquid in model, also can guarantee that medicinal operation sense of reality.
Summary of the invention
The invention provides a kind of teaching simulation syringe rational in infrastructure, can produce the sense of reality of medicinal, easily cause the security hidden troubles such as short circuit when being avoided that again injecting fluid touch sensor or internal circuit, effectively solve these not enough.
The invention is achieved mainly through following technical proposals: teaching simulation syringe, it is characterised in that: it is made up of outer sleeve, inner sleeve and the dynamic piston that is equipped with in inner sleeve, a check valve, a coupling cock device；
A described coupling cock device includes a sealing-plug, coupling cock main body, conduit, for UNICOM and the connection closing UNICOM's outer sleeve and inner sleeve space, and can inject liquid in outer sleeve, inner sleeve by coupling cock main body；
Described teaching simulation syringe, it is also possible to comprise a simulation syringe needle；
Described check valve can be changed direction and use；
There is a pore on described outer sleeve top, and diameter is less than 0.1 millimeter；
Simulation syringe needle is connected on the conehead of inner sleeve by check valve, if now check valve allows liquid to enter in inner sleeve by syringe needle, so can fill in tight blocking and close the connection of inner sleeve and outer sleeve, liquid is allowed to be directly entered in inner sleeve by the rearward movement of piston, then turning on coupling cock device makes inner sleeve and outer sleeve be attached, when simulating puncture injection, liquid is because the effect of check valve and coupling cock device open-minded, piston promotes liquid to enter in overcoat barrel chamber, without injecting liquid into inside model, avoid and allow the risk of short circuit because liquid penetrates into；Discharge if the now arrangement of check valve does not allow liquid to pass through simulation syringe needle, so open coupling cock device, liquid is injected from sealing consent, allow liquid pass through conduit and enter in overcoat barrel chamber, after be stoppered sealing-plug, when simulating injecting fluid, under the suction movement of piston, liquid in outer sleeve enters in inner sleeve by coupling cock device, when piston promotes the liquid of inner sleeve, liquid just enters outer sleeve intracavity further through coupling cock device, liquid will not pass through to simulate in syringe needle injection model, it is to avoid allow the risk of short circuit because liquid penetrates into；If model itself needs injecting fluid just can carry out all kinds of education activities, first overcoat barrel chamber can being filled liquid, then draw fluid in inner sleeve, close coupling cock device, under the promotion of piston, liquid is from check valve and by simulating in syringe needle injection model；According to the first situation, simulation syringe needle pumping liquid can also be first passed through and enters inner sleeve intracavity, then change the direction of check valve, be injected in model again through the check valve after changing direction.
The invention has the following advantages:
1. can be effectively prevented from contact model inner sensor or circuit and cause short-circuit potential safety hazard；
2. can simulate the puncture skill training of medicinal.

Detailed description of the invention
The teaching of the invention simulation syringe as shown in drawings, is formed 6 by outer sleeve 2, inner sleeve 3 and dynamic piston 1, check valve 4, the coupling cock device being equipped with in inner sleeve；Coupling cock device includes a sealing-plug 9, coupling cock main body 10, conduit 11, for UNICOM and the connection closing UNICOM's outer sleeve 2 and inner sleeve 3 space, and can inject liquid in outer sleeve 2, inner sleeve 3 by coupling cock main body；There is a pore 12 on outer sleeve 2 top, and diameter is less than 0.1 millimeter；A simulation syringe needle 5 can be contained again.
Simulation syringe needle 5 is connected on the conehead 13 of inner sleeve by check valve, if now check valve 4 allows liquid to pass through in syringe needle entrance inner sleeve 3, so can fill in tight blocking 9 and close inner sleeve 3 and the connection of outer sleeve 2, liquid is allowed to be directly entered in inner sleeve 3 by the suction movement backward of piston 1, then turning on coupling cock device 6 makes inner sleeve 3 and outer sleeve 2 be attached, when simulating puncture injection, liquid is because check valve 4 can only the effect of one-way flow and coupling cock device 6 open-minded, piston 1 promotes liquid to enter in outer sleeve 2 chamber, without injecting liquid into inside model, avoid and allow the risk of short circuit because liquid penetrates into, simulate the operating process that syringe uses simultaneously.
If now the arrangement direction of check valve 4 do not allow liquid pass through simulation syringe needle 5 discharge, so open coupling cock device 6, liquid is injected from sealing-plug 9 hole, allow liquid pass through conduit 11 and enter in outer sleeve 2 chamber, after be stoppered sealing-plug 9, when simulation suction, during injecting fluid, under the suction movement of piston 1, liquid in outer sleeve enters in inner sleeve 3 by coupling cock device 6, when piston 1 promotes the liquid of inner sleeve 3, liquid just enters outer sleeve 2 intracavity further through coupling cock device 6, liquid will not pass through to simulate in syringe needle 5 injection model, avoid and allow the risk of short circuit because liquid penetrates into.
If model itself needs injecting fluid just can carry out all kinds of education activities, first outer sleeve 2 chamber can be filled liquid, then draw fluid in inner sleeve 3, close coupling cock device 6, under the promotion of piston 1, liquid is from check valve 4 and by simulating in syringe needle 5 injection model；According to the first situation, simulation syringe needle 5 pumping liquid can also be first passed through and enters inner sleeve 3 intracavity, then change the direction of check valve 4, be injected in model again through the check valve 4 after changing direction.
These are all to reach for the purpose of simulation practical operation injection, to improve the effect of the sensations such as true operation injection, puncture, suction, it is possible in selection does not allow liquid from needle tubing stream to model, it is to avoid some models do not allow to inject the potential safety hazard of liquid；Also can realize injecting liquid in the model allowing to inject liquid, it is achieved simulation injection, the sensation punctured；The operation of suction can also be practised from model content liquid capsule.
