Abstract
An external chest compression depth detection structure mainly consists of a press rod, a conductive plastic potentiometer, a gear and a rack, wherein the gear is connected with the press rod, the gear is fixed on a bearing of the conductive plastic potentiometer, and the gear and the rack are buckled through teeth. The gear can be driven to slide on the rack through pushing the press rod, at the same time, the bearing of the conductive plastic potentiometer rotates to generate mechanical displacement, the conductive plastic potentiometer converts the mechanical displacement into electric signals, and the displacement generated by the press rod can be reflected through the change of the electric signals, i.e. the compression depth change can be reflected. Thereby, the compression depth can be recorded. When the method is used for detecting the compression depth, the measurement precision is high, the response speed is high, the repetitiveness is good, and the reliability is high.
Description
Technical field
The utility model relates to a kind of medical teaching utensil, relates in particular to the external chest compression training of cardio-pulmonary resuscitation training model.
Background technology
The cardio-pulmonary resuscitation training model is quite commonly used in present medical teaching, and it helps to train people to grasp correct first aid technical ability.Rescuer one palm root is close to the chest compression position when carrying out external chest compression, and another palm is placed on this back of the hand, and the parallel overlapping and finger of two hands intersects to hold slightly mutually and lifts, and makes the dislocation of finger joint from the wall of the chest.The rescuer both arms should be exceptionally straight, and the both shoulders middle point vertical utilizes upper part of the body body weight and shoulder, arm muscles strength to push vertically downward in pushing the position.Pushing should be steadily, carry out regularly, can not be interrupted, and presses down with upwards the time of loosening equates; Be pressed into the minimum point place, Ying Youyi significantly pauses, and violent pressure or great-jump-forward that can not impact type be pushed; The palm root of location does not leave chest by two pieces of jade put together position when loosening, but should loosen as far as possible, makes breastbone not be subjected to any pressure.Compression frequency is 80～100 times/minute, children's 90～100 times/minute, and pushing with loosening time scale served as appropriate with 0.6: 0.4.With the ratio of breathing with above-mentioned.According to pressing depth the adult is 4～5cm, 5～13 years old person 3cm, baby, child 2cm.Pushed deeply or shallow excessively, all do not reach expected effect.
Cardiopulmonary resuscitation model is in the past according to pressing depth using grating sensor in the detection, and its shortcoming is that resolution is low, and transmission speed is slow, and easily forms accumulated error.
Summary of the invention
In order to address the above problem, make medicos can grasp masterful technique, should be applicable to teaching, be applicable to examination again, the degree of depth that has adopted a kind of conductive plastic potentiometer measurement to push here.
Technical solution adopted in the utility model is: it mainly is made up of depression bar, conductive plastic potentiometer, gear, tooth bar.Gear links to each other with depression bar, and gear is fixed on the bearing of conductive plastic potentiometer, and wheel and rack tooth tooth interlocks.Promote depression bar, but driven gear slides the bearing of conductive plastic potentiometer rotation simultaneously, generation mechanical shift on tooth bar.Conductive plastic potentiometer converts a mechanical shift to electric signal, and this signal can be directly proportional with mechanical motion.Reflect the displacement that depression bar takes place, the change in depth of promptly pushing by change in electric.
The beneficial effects of the utility model are, the precision height of measurement, and response speed is fast, good reproducibility, reliability height.
Description of drawings
Accompanying drawing is the synoptic diagram of this structure.1 depression bar among the figure, 2 conductive plastic potentiometers, 3 gears, 4 tooth bars.
Embodiment
Be described further below in conjunction with accompanying drawing.
As shown in drawings, when carrying out the external chest compression operation, push the chest skin on the first aid human model, press depression bar.Driven gear moves on tooth bar, and the bearing on the potentiometer also rotates thereupon, produces mechanical shift.Conductive plastic potentiometer converts a mechanical shift to electric signal, and this signal can be directly proportional with mechanical motion.Can note the degree of depth of pushing like this.The brush assembling is connected to mechanical actuator, makes plastics resistance rail produce a voltage divider then.Potentiometric resistance rail two ends are connected to galvanic current and press.When at brush with revise when measuring between the resistance rail, signal voltage is the major part of voltage divider, and is directly proportional with brush position on the resistance rail.Conductive plastic potentiometer can focus on the accuracy of the all-in resistance on the resistance rail as a voltage divider, because temperature fluctuation can not have influence on measurement result only to resistance generation effect.
The above, only being the utility model preferred embodiment, is not that the utility model is done any pro forma restriction, and all foundations technical spirit of the present utility model is to any simple modification that above embodiment did, equivalent variations and modification still belong in the scope of technical solutions of the utility model.
