Abstract

The utility model relates to an electronic teaching aid which has a pregnant woman half-body model. Magnetic conductive blocks are respectively buried at the auscultation position of the abdominal fetal heart, the right front point of a pillow, the right front point of a sacrum, the transverse point, the left front point of the pillow and the left front point of the sacrum; an electric electromagnetic induction probe is arranged in the utility model, and a recording and playing device enlarges a fetal heart sound tape or stops playing the tape with a probe control relay; the electronic demonstration teaching instrument is applied, and students achieve the purposes of correctly hearing fetal heart sound and correctly judging the fetal position through the visual teaching of sound, model and position.

Description

The electronics fetal heart sound position of foetus is shown teaching appliance

The utility model relates to teaching aid, is a kind of electronic instruction instrument of listening to the fetal heart sound position of foetus.

The fetal heart sound auscultation is that clinical ob-gyn, women and children assistant doctor, midwife are used for understanding fetus in the situation of in utero surviving, and an indispensable inspection technical ability, be the basic training that to grasp, the different clinically position of foetus have its different auscultation position, just before giving birth back fetal rhythm rate also changes to some extent along with the variation of uterine contraction.In present teaching, also there is not this teaching appliance, the teacher can only carry out oral description to fetal heart sound on the classroom, often be difficult for making the student that very dark understanding is arranged, so teaching efficiency is poor.

The purpose of this utility model is the electronic instruction instrument that a kind of electronics fetal heart sound position of foetus will be provided, in obstetrics' teaching, make students' any time in the classroom to solve, and do not have all can listen under patient's the environment feature of the position of foetus-fetal rhythm rate of required grasp, improve auscultation and the distinguishing ability of student fetal rhythm.

Concrete scheme of the present utility model is: get one of pregnant woman's bust form, and one of videocorder, and be ready to the tape that a box is recorded fetal heart sound; Then at the belly intermittent auscultation position of pregnant woman's bust form: place, right occipitoanterior (ROA), the right front place of sacrum, transverse presentation place, left occipitoanterior (LOA) place, the left front place of sacrum are embedded with magnetic inductive block respectively; And having an energising electromagnetic inductive probe, this probe pilot relay is controlled the videocorder playback again or is parked.

Its principle of work is summarized as follows:

The probe of this Teaching instrument can arbitrarily move freely by abdomen outside pregnant woman's bust form, and the mode of its checked operation is almost sought the process striking resemblances that the real human body fetal heart sound is determined the position of foetus with Doppler's fetal rhythm Ultrasound Instrument of clinical use, is really true to life.When alignment probe was simulated the magnetic inductive block of fetal rhythm position, the action of probe inductive switch made the videocorder playback by relay; When probe leaves the magnetic inductive block of fetal rhythm position, videocorder will be parked.

This teaching appliance can be listened the fetal rhythm rate that is taken at the different position of foetus, the platform dish vascular murmur when placental abnormality is adhered to.Use this electronics Teaching instrument teaching, the student reaches and correctly listens to fetal heart sound by the object teaching of sound (sound), type (model), position (position), correctly judges the purpose of the position of foetus.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a general structure synoptic diagram of the present utility model;

Fig. 2 is a model vertical view of the present utility model.

Embodiment: referring to Fig. 1, Fig. 2 makes 1 one of pregnant woman's bust forms, at five intermittent auscultation positions of belly of model: 6 places, right occipitoanterior (ROA), right front 7 places of sacrum, transverse presentation 8 places, left occipitoanterior (LOA) 9 places, left front 10 places of sacrum are embedded with magnetic inductive block 2 respectively; Purchase an electromagnetic inductive probe 3 (model is LJM30A-15J/K), a relay 4 (model is LFY3), a videocorder 5, and record a dish fetal heart sound tape and put into videocorder, then electromagnetic inductive probe 3 energized are connected in series relay 4 simultaneously, 4 control videocorders 5 of relay.

Claims

1. a kind of electronics fetal heart sound position of foetus that is used to impart knowledge to students is shown teaching appliance, the fetal heart sound tape that has pregnant woman's bust form, videocorder and record, it is characterized in that: at the belly intermittent auscultation position of pregnant woman's bust form, the place, right occipitoanterior (ROA), the right front place of sacrum, the transverse presentation place, the left occipitoanterior (LOA) place, the left front place of sacrum is embedded with magnetic inductive block respectively; And having an energising electromagnetic inductive probe, this probe pilot relay is controlled videocorder again.
