The injector also comprises a simulation probe. The direction of the one-way valve can be changed for use. The top of the external sleeve is provided with a gas hole, wherein the diameter of the gas hole is less than 0.1mm. The injector can effectively prevent the contact with a sensor or circuit in a model from causing the short-circuit potential safety hazard, and can simulate the clinic puncture training.
Description
Technical field
The invention relates to a kind of teaching syringe, particularly relate to one can select not by liquid from injection pin hole discharge, also can model fluid discharge teaching simulate injection device.
Background technology
In medical teaching process, student, when practising the operative skills such as puncture, injection, suction, first will judge darting station, the degree of depth, in order to avoid cause unnecessary damage to patient.The analogy model inside used in hands-on is often equipped with the power device such as sensor, circuit board of some, in addition current used material can not live through puncture repeatedly, otherwise will leak, if user does not note causing short circuit phenomenon, produce certain security hidden trouble.For this reason, model designer also multipair circuit, sensor carries out the adjustment of position, makes in a model away from the position of leakage.But the still unescapable needs had and liquid comes into contact.Be badly in need of a kind of analog simulation syringe that can be supporting with teaching mode, can the process of realistic simulation injecting fluid, again can not by liquid injection model; Meanwhile, just can play when really simulating if need to inject liquid, also can liquid is injected in model, also can ensure the medicinal operation sense of reality.
Summary of the invention
The invention provides a kind of teaching simulate injection device rational in infrastructure, can produce the sense of reality of medicinal, can avoid again easily causing the security hidden troubles such as short circuit when injecting fluid feeler or internal circuit, these deficiencies of effective solution.
The invention is achieved mainly through following technical proposals: teaching simulate injection device, is characterized in that: by outer sleeve, inner sleeve and dynamic be equipped with piston in inner sleeve, a retaining valve, a coupling cock device form;
A described coupling cock device comprises a sealing-plug, coupling cock main body, conduit, for UNICOM and the connection of closing UNICOM's outer sleeve and inner sleeve space, and in outer sleeve, inner sleeve, injects liquid by coupling cock main body;
Described teaching simulate injection device, can also comprise a simulation syringe needle;
Described retaining 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 retaining valve, if now retaining valve allows liquid to enter in inner sleeve by syringe needle, so can jam-pack sealing-plug close the connection of inner sleeve and outer sleeve, liquid is allowed directly to be entered in inner sleeve by the motion backward of piston, opening coupling cock device subsequently makes inner sleeve be connected with outer sleeve, when simulating puncture injection, liquid is because the effect of retaining valve and the open-minded of coupling cock device, piston promotes liquid and enters in outer sleeve chamber, and liquid can not be injected into model inside, avoid and to allow the risk of short circuit because liquid infiltrates, discharge if the now arrangement of retaining valve does not allow liquid to pass through simulation syringe needle, so open coupling cock device, liquid is injected from sealing consent, liquid is allowed to enter in outer sleeve chamber by conduit, after be stoppered sealing-plug, when simulate injection liquid, 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 in outer sleeve chamber by coupling cock device again, and liquid can not by simulation syringe needle injection model, avoids to allow the risk of short circuit because liquid infiltrates, if when model itself needs injecting fluid just can carry out all kinds of education activities, first outer sleeve chamber can be filled liquid, then by liquid suction inner sleeve, close coupling cock device, under the promotion of piston, liquid is from retaining valve and by simulation syringe needle injection model, also according to the first situation, first can enter in inner sleeve chamber by simulation syringe needle pumping liquid, then change the direction of retaining valve, then be injected in model by the retaining valve after changing direction.
The invention has the following advantages:
1. effectively can avoid contact model inner sensor or circuit and cause the potential safety hazard of short circuit;
2. can simulate the puncture skill training of medicinal.

Embodiment
The teaching of the invention simulate injection device as shown in drawings, forms 6 by outer sleeve 2, inner sleeve 3 and dynamic piston 1, retaining valve 4, the coupling cock device be equipped with in inner sleeve; Coupling cock device comprises a sealing-plug 9, coupling cock main body 10, conduit 11, for UNICOM and the connection of closing UNICOM's outer sleeve 2 and inner sleeve 3 space, and in outer sleeve 2, inner sleeve 3, injects liquid by coupling cock main body; There is a pore 12 on outer sleeve 2 top, and diameter is less than 0.1 millimeter; Can again containing a simulation syringe needle 5.
Simulation syringe needle 5 is connected on the conehead 13 of inner sleeve by retaining valve, if now retaining valve 4 allows liquid to enter in inner sleeve 3 by syringe needle, so can jam-pack sealing-plug 9 close the connection of inner sleeve 3 and outer sleeve 2, liquid is allowed directly to enter in inner sleeve 3 by the suction movement backward of piston 1, opening coupling cock device 6 subsequently makes inner sleeve 3 be connected with outer sleeve 2, when simulating puncture injection, liquid is because retaining valve 4 can only the effect of one-way flow and the open-minded of coupling cock device 6, piston 1 promotes liquid and enters in outer sleeve 2 chamber, and liquid can not be injected into model inside, avoid and to allow the risk of short circuit because liquid infiltrates, simulate the operating process that syringe uses simultaneously.
If now the arrangement direction of retaining 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, liquid is allowed to enter in outer sleeve 2 chamber by conduit 11, 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 in outer sleeve 2 chamber by coupling cock device 6 again, liquid can not by simulation syringe needle 5 injection model, avoid and to allow the risk of short circuit because liquid infiltrates.
If when model itself needs injecting fluid just can carry out all kinds of education activities, first outer sleeve 2 chamber can be filled liquid, then by liquid suction inner sleeve 3, close coupling cock device 6, under the promotion of piston 1, liquid is from retaining valve 4 and by simulation syringe needle 5 injection model; Also according to the first situation, first can enter in inner sleeve 3 chamber by simulation syringe needle 5 pumping liquid, then change the direction of retaining valve 4, then be injected in model by the retaining 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, can select not allow liquid flow in model from needle tubing, avoid some models not allow to inject the potential safety hazard of liquid; Also can realize liquid being injected into permission to inject in the model of liquid, realize the sensation of simulate injection, puncture; Also the operation of aspirating can be practised from model content liquid capsule.
