The medical puncture simulation teaching device comprises a silicon rubber surface layer, a vertebra model, a rubber thin film, an induction coil X1 and an electronic simulation device, wherein the induction coil X1 is connected with the electronic simulation device. The medical puncture simulation teaching device has the advantages that an electronic indication mode is employed, liquid leakage is avoided, and the device is simple and can be used repeatedly.
Description
Technical field
The utility model relates to a kind of puncture analog equipment, relates in particular to a kind of medical science puncture simulation teching device, belongs to the medical educational field.
Background technology
Can puncture technique be a basic fundamental in clinical treatment and the rescue work, rapidly, accurately, once successfully accomplish the key that puncture is treatment patient disease, rescue patient life.Puncture technique is the scale that embodies the clinical nurse professional ability, and puncture technique is unskilled, and stress, anxious state of mind etc. in the operation cause often once success of puncture, influence treatment, nursing, even cause the dispute that some are unnecessary.And employed various puncturing patterns in the present stage colleges and universities real standard course cost an arm and a leg, and serviceable life is short, causes the chance of student's hands-on to significantly reduce, and have influenced the skill level that puncture technique is grasped.Whether existing puncture anthropomorphic dummy adopts the mode of liquid indication to remind the operator to puncture and puts in place.This class methods repeatability is relatively poor, and puncture back liquid storage part seepage occurs because of pin hole several times usually, and the frequent change liquid storage partly makes use cost increase, and is unfavorable for large-scale teaching practice.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of medical science puncture simulation teching device, adopts the electronics indication, the no liquid seepage; Device is simple, and reusable number of times is more.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of medical science puncture simulation teching device; Comprise the silicon rubber top layer; Vertebrae model, rubber film; Inductive coil X1 and electronic simulation, inductive coil X1 is connected with electronic simulation, and said electronic simulation comprises inductance L 1, inductance L 2, inductance L 3, operational amplifier U1, comparer U2, resistance R 1 and resistance R 2, capacitor C 1, a light emitting diode D1, an AC power P1, a direct supply P2; Inductive coil X1 and inductance L 1, inductance L 2, inductance L 3 constitute an electric bridge, and the tie point of inductive coil X1 and inductance L 2 meets AC power P1, the tie point ground connection of inductance L 1 and inductance L 3; The tie point of inductive coil X1 and inductance L 1 connects the backward end of operational amplifier U1; The tie point of inductance L 2 and inductance L 3 connects the forward end of operational amplifier U1, the forward end of the output termination comparer U2 of operational amplifier U1, and capacitor C 1 is output terminal and the ground of concatenation operation amplifier U1 respectively; After resistance R 1 is connected with resistance R 2; Resistance R 1 meets direct supply P2, resistance R 2 ground connection, and the tie point of resistance R 1 and R2 connects the backward end of comparer U2; The output terminal sending and receiving optical diode D1 of comparer U2 is anodal, the minus earth of light emitting diode D1.
Said inductive coil X1 is installed in the target area of puncture.
The beneficial effect of the utility model is: adopt the electronics indication, the no liquid seepage; Device is simple, and reusable number of times is more.
Description of drawings
Fig. 1 is the circuit diagram of the utility model;
Fig. 2 is the structural representation of the utility model;
Among the figure: 1, silicon rubber top layer, 2, the vertebrae model, 4, rubber film.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Like Fig. 1, shown in Figure 2; The utility model comprises silicon rubber top layer 1; Vertebrae model 2, rubber film 4; Inductive coil X1 and electronic simulation, inductive coil X1 is connected with electronic simulation, and said electronic simulation comprises inductance L 1, inductance L 2, inductance L 3, operational amplifier U1, comparer U2, resistance R 1 and resistance R 2, capacitor C 1, a light emitting diode D1, an AC power P1, a direct supply P2; Inductive coil X1 and inductance L 1, inductance L 2, inductance L 3 constitute an electric bridge, and the tie point of inductive coil X1 and inductance L 2 meets AC power P1, the tie point ground connection of inductance L 1 and inductance L 3; The tie point of inductive coil X1 and inductance L 1 connects the backward end of operational amplifier U1; The tie point of inductance L 2 and inductance L 3 connects the forward end of operational amplifier U1, the forward end of the output termination comparer U2 of operational amplifier U1, and capacitor C 1 is output terminal and the ground of concatenation operation amplifier U1 respectively; After resistance R 1 is connected with resistance R 2; Resistance R 1 meets direct supply P2, resistance R 2 ground connection, and the tie point of resistance R 1 and R2 connects the backward end of comparer U2; The output terminal sending and receiving optical diode D1 of comparer U2 is anodal, the minus earth of light emitting diode D1.Inductive coil X1 is installed in the target area of puncture.
When the utility model uses inductive coil is placed in the target area of puncture; When operator's puncture needle thrusts the target area, promptly syringe needle gets into inductive coil X1, causes that the reactance value of inductive coil X1 changes; Signal amplifies through operational amplifier U1; Make comparer U2 upset, light emitting diode D1 lights, and indication is punctured successfully.If puncture needle does not get into the target area, promptly syringe needle does not get into inductive coil X1, and the reactance value of inductive coil X1 does not change, and light emitting diode D1 does not work, and the indication puncture does not put in place.
