Abstract
The utility model belongs to medical education field, more particularly to a kind of new Medical teaching simulated injection device and simulation system, wherein Medical teaching simulated injection device includes empty cylinder, piston, piston shaft, the piston handle being inserted in empty cylinder, it is sealed at the sky cylinder nipple, the piston is the hollow pipeline for filling liquid, and the front center of the hollow pipeline is equipped with opening.The piston of the utility model is the hollow pipeline for filling liquid, and when twitching piston, by negative pressure, liquid is gradually sucked in empty cylinder in hollow pipeline；Upon injection, by pressure, again into hollow pipeline, the liquid in empty cylinder gradually decreases liquid；Both simulated injection has been achieved the purpose that, liquid has also been avoided to be discharged in manikin, model is caused to damage, liquid is also greatly saved and operator takes out the time of liquid.
Description
Technical field
The utility model belongs to medical education field, and in particular to a kind of new Medical teaching simulated injection device and injection
Simulation system.
Background technology
Medical college student is when injecting practice, the operation practice typically on the human simulation model of filling sponge,
In injection, liquid can be injected into the sponge inside model, and after long term injections, manikin easily rots and breakage, together
When syringe in liquid medicine injected after also need to aspirate again, waste liquid and the time of operator.
The content of the invention
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of simple in structure, easy to use
Medical teaching simulated injection device.
A kind of Medical teaching simulated injection device, including empty cylinder, piston, piston shaft, the piston handle being inserted in empty cylinder are described
It is sealed at empty cylinder nipple, the piston is the hollow pipeline for filling liquid, and the front center of the hollow pipeline is equipped with opening.
Preferably, the empty cylinder nipple end is sealed by sealing element.
Preferably, the syringe needle on empty cylinder is further included.
It is furthermore preferred that the sealing element material is PE or PP.
Preferably, the front center opening of the hollow pipeline is the circular hole of diameter 1mm.
It is furthermore preferred that the piston is made of opaque material.
In addition, the utility model additionally provides a kind of simulation system.
A kind of simulation system including Medical teaching simulated injection device, is further included for injecting the manikin of practice,
Medical teaching simulated injection device, including empty cylinder, piston, piston shaft and the piston handle being inserted in empty cylinder, at the sky cylinder nipple
Sealing, the piston are the hollow pipelines for filling liquid, and the front center of the hollow pipeline is equipped with opening.
Preferably, the empty cylinder nipple end is sealed by sealing element.
Preferably, the syringe needle on empty cylinder is further included.
It is furthermore preferred that the sealing element material is PE or PP.
Preferably, the front center opening of the hollow pipeline is the circular hole of diameter 1mm.
It is furthermore preferred that the piston is made of opaque material.
Preferably, the manikin is equipped with phosphor region in injection site.
The piston of the utility model is the hollow pipeline for filling liquid, when twitching piston, by negative pressure, and liquid in hollow pipeline
Body is gradually sucked in empty cylinder；When injecting (promotion piston), by pressure, liquid is again into hollow pipeline, the liquid in empty cylinder
It gradually decreases；Both simulated injection has been achieved the purpose that, liquid has also been avoided to be discharged in manikin, model is caused to damage, also saved significantly
It has saved liquid and operator takes out the time of liquid.
Description of the drawings
Fig. 1 is the sectional view of the utility model embodiment 1.
Fig. 2 is the manikin structure diagram of the utility model embodiment 2.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1, a kind of Medical teaching simulated injection device, including empty cylinder 1, is arranged on empty 1 inner carrier 2 of cylinder, piston shaft
3 and piston handle 3-1, empty cylinder 1 are equipped with liquid outlet 1-1, and liquid outlet 1-1 is equipped with sealing element 1-2, and (the sealing element 1-2 materials are
PE or PP), the piston 2 is the hollow pipeline 2-2 for holding liquid, and the front center of hollow pipeline 2-2 is equipped with opening 2-1,
Liquid can flow into empty cylinder 1 from hollow pipeline 2-2.
In practice, the liquid of hollow pipeline 2-2 is drawn onto in empty cylinder 1 user by pumpback piston handle 3-1 by negative pressure,
Then syringe needle is mounted on empty cylinder 1.
During simulated injection, syringe needle is penetrated into human injection's model, promotes piston handle 3-1, by pressure by liquid squeeze to
In the hollow pipeline 2-2 of piston 2, the process of analog drug water injection to human body.
When reusing, piston handle 3-1 is twitched, makes to generate negative pressure in empty cylinder 1, with twitch piston 2, hollow pipeline 2-2
Interior liquid is entered by the opening 2-1 on piston face in empty cylinder 1, and simulated injection device takes out the process of liquid.
Embodiment 2
Such as Fig. 2, the simulation system of Medical teaching simulated injection device and manikin composition described in embodiment 1,
For acupoint injection therapy model 100, (injection model may also be only human upper limb or lower limb model or other notes to middle manikin
Penetrate site model), the model is to be equipped with the injection zone 101 of fluorescence mark at the acupuncture point of human body.It is irradiated by torch, detection note
Position is penetrated whether in phosphor region 101, to judge whether injection position is correct.
