in order to make medical personnel judge whether the injection exercise is successful or not, two conducting rings 9 are arranged on the injection needle 8, specifically, the needle point and the middle part of the injection needle 8 are fixedly connected with the conducting rings 9, the injection and the puncture are finished only after the two conducting rings 9 on the injection needle 8 completely enter the through hole 6, the needle body of the injection needle 8 in the form is made of an insulating material, only the conducting rings 9 are conductors, the two conducting rings 9 are respectively and electrically connected with corresponding indicating lamps 10 through cables, the two indicating lamps 10 are respectively and electrically connected with a battery 11, the conducting material inside the through hole 6 is also electrically connected with the battery 11 (the inner side wall of the mounting frame 5 is fixedly connected with a conducting rod matched with the through hole 6, one end of the conducting rod can be inserted into the through hole 6, the other end of the conducting rod is electrically connected with the battery 11 through a spring cable 29 fixedly connected to the mounting rod 12, and the arrangement of the spring cable 29 can not influence the movement of the mounting frame 5 in the base frame 2);
when the injection and puncture work is carried out, the two indicator lights 10 are turned on when the two conducting rings 9 on the injection needle 8 completely enter the through hole 6, which represents that the injection and puncture work is successful;
when the injection puncture is carried out, the indicator light 10 electrically connected with the conducting ring 9 at the needle point position is turned off after being turned on, and the indicator light 10 electrically connected with the conducting ring 9 at the middle part of the injection needle 8 is turned on, so that the injection puncture angle is overlarge (namely, the included angle between the angle of the injection needle 8 and the silica gel pad is overlarge (the space of the through hole 6 cannot directly accommodate the injection needle 8), or the injection position is deviated, so that the central area of the through hole 6 is not punctured;
when the injection puncture is carried out, the indicator light 10 electrically connected with the conducting ring 9 at the needle point position is always on, and the indicator light 10 electrically connected with the conducting ring 9 at the middle part of the injection needle 8 is not always on, which means that the injection puncture angle is too small (namely, the included angle between the angle of the injection needle 8 and the silica gel pad is too small, so that the depth is not enough, and the conducting ring 9 at the middle part does not enter the through hole 6);
when the injection puncture work is carried out, the two indicator lights 10 are not lighted at all, namely, the puncture positions are completely deviated.
Example two:
in order to facilitate the medical staff to judge the deviation when the injection and puncture work fails, an arc groove 7 is provided, specifically, an arc groove 7 with an upward opening is provided on the silica gel block 4 at the periphery of the through hole 6, a deformable conductive material is filled in the groove 7, the conductive materials in the through hole 6 and the groove 7 are respectively electrically connected with a corresponding indicator light 10, a conductive rod matched with the through hole 6 and the groove 7 is fixedly connected on the inner side wall of the mounting frame 5, one end of the conductive rod can be inserted into the through hole 6 and the groove 7, the other end is electrically connected with the indicator light 10 through a spring cable 29 fixedly connected on the mounting rod 12, the arrangement of the spring cable 29 can not affect the movement of the mounting frame 5 in the base frame 2, the two indicator lights 10 are respectively electrically connected with the battery 11, the injection needle 8 is also electrically connected with the battery 11, when the injection needle 8 is inserted into the through hole 6, the indicator light 10 electrically connected with the conductive material inside the through hole 6 is turned on, when the injection needle 8 is inserted into the empty slot 7, the indicator light 10 electrically connected with the conductive material inside the empty slot 7 is turned on, and the material of the needle body of the injection needle 8 is a conductor (which is simpler than the first one);
after the needle insertion is completed during the injection and puncture work, the indicator light 10 electrically connected with the conductive material in the through hole 6 still keeps on, and the indicator light 10 electrically connected with the conductive material in the empty groove 7 does not light, which means that the puncture work is successful (the medical staff judges whether the needle insertion has enough length by observing the length of the needle body of the injection needle 8 positioned outside the silica gel pad);
when the injection and puncture work is carried out, the indicator light 10 electrically connected with the conductive material in the through hole 6 is firstly lightened, and then the indicator light 10 electrically connected with the conductive material in the empty groove 7 is lightened, namely, the injection and puncture work failure of the injection needle 8 penetrating through the through hole 6 is represented, the needle inserting angle is deviated (or the included angle between the angle of the injection needle 8 and the silica gel pad is too large), and the adjustment can be carried out when the next exercise is carried out;
when the injection puncture work is carried out, the indicator light 10 electrically connected with the conductive material in the empty slot 7 is firstly lightened, and the indicator light 10 electrically connected with the conductive material in the through hole 6 is then lightened, so that the needle inserting position and angle are not standard, the angle of the needle firstly entering the side and then entering the through hole 6 is inclined, and the needle inserting position and the angle can be slightly adjusted in the next exercise;
when the injection puncture work is carried out, the indicator light 10 electrically connected with the conductive material in the empty groove 7 is always on, and the indicator light 10 electrically connected with the conductive material in the through hole 6 is not on, namely, the injection puncture work fails, and the needle inserting position slightly deviates, but the deviation position is not large, so that the corresponding adjustment can be carried out when the next exercise is carried out;
when the injection and puncture work is carried out, the two indicating lamps 10 are not all lightened, the fact that the injection needle 8 is completely pricked and deflected is represented, the injection and puncture work fails, the puncture position has large deflection, and the position can be searched again for practice in the next practice.
The medical staff can operate the control module 43 to control the start and stop of the sliding motor 15 and the push-pull electromagnet 42 by the keys arranged on the base 1.
The push-pull electromagnet 42 and the control module 43 both have publicly used technical solutions, and the structure and principle thereof are not the technical features of the present invention, and therefore are not described in detail, for example: the push-pull electromagnet 42 may be of the type U0530S-24A28 and the control module may be of the type WG 236.
For the above embodiments, the inner ends of the spring cables 29 can be led in from the side of the mounting frame 5 without the turning plate 30 and then electrically connected with the conductive rods, thereby realizing circuit connection.
The working principle is as follows: medical personnel handheld syringe needle 8 when using, make syringe needle 8 alignment through-hole 6 according to the judgement of oneself, later can inject the exercise, when the action of injecting the puncture goes on, the condition of lighting (quantity, sequence) through pilot lamp 10, judge whether the injection exercise is successful, later can control module 43 promptly and make sliding motor 15 start, adjust the position of silica gel piece 4 in 2 insides of basic frame, thereby can carry out the exercise next time, continuous repetition above-mentioned step can be continuous practise.
