Description
Technical field
This utility model relates to technical field of medical instrument, is more particularly a kind of electronic nerve detection hammer.
Background technology
Neurosurgeon is when checking to the nerve of patient, knee jerk is the inspection method of conventional a kind of nervous physiology reflection, mainly adopt this inspection utensil of percussion hammer clinically at present, by knocking patient's knee, realize the detection of knee jerk.But in whole testing process, doctor wants the time drawing knee jerk, also need in addition by the clocking capability of stopwatch, thus, medical personnel will change between different utensils, waste time and energy, add the trouble of operation, also reduce work efficiency; On the other hand, completing of timing course, what only rely on is naked eyes and the manual operation of doctor, unavoidably can be variant in precision, the accuracy of measurement result needs improved further.Therefore, how to be effectively combined with manual time-keeping by percussion hammer, and by automatically, the form of electronization completing timing statistics, is a department of neurology staff difficult problem urgently to be resolved hurrily.
Utility model content
The problem that this utility model mainly solves is to provide a kind of electronic nerve detection hammer, traditional percussion hammer and the manual time-keeping device of electronization are effectively combined in one, while medical personnel knock patient's knee, complete the timing course of knee jerk voluntarily, achieve the automatization that knee jerk checks, not only reduce the trouble of doctor's operation, improve work efficiency, also substantially increase the accuracy of detection architecture.
For solving the problem, this utility model adopts following technical scheme:
A kind of electronic nerve detection hammer, comprising: hammer body, the hammer handle be connected with described hammer body; Wherein, the inside, front end of described hammer body arranges pressure transducer, and described hammer handle front end arranges manual time-keeping parts and LCDs, and arrange with described hammer body homonymy and parallel contact arm in the middle part of described hammer handle, described hammer handle rear end arranges power supply unit; Described contact arm front end arranges spongy body, arranges pressure-sensitive switch in described spongy body; Described pressure transducer is connected by internal wiring with described manual time-keeping parts and LCDs respectively, and described pressure-sensitive switch is connected by internal wiring with described manual time-keeping parts; Described power supply unit is connected with described pressure transducer, manual time-keeping parts, LCDs and pressure-sensitive switch.
Preferably, described manual time-keeping parts and LCDs are positioned at top or the side of described hammer handle front end.
Preferably, described manual time-keeping parts are high accuracy timer second, and precision is more than 0.001 second.
Preferably, the length of described contact arm is less than hammer body length.
Preferably, described power supply unit is built-in rechargeable battery or external detachable battery.
Owing to adopting technique scheme, this utility model has following superiority:
1, this electronic nerve detection hammer structure is simple, easy and simple to handle;
2, traditional percussion hammer and the manual time-keeping device of electronization are effectively combined in one, decrease the trouble that medical personnel change between different utensil;
3, while medical personnel knock patient's knee, the timing course of knee jerk can be completed voluntarily, achieve the automatization that knee jerk checks, improve work efficiency;
4, LCDs can clear display patient's percussion power size of bearing and knee jerk time corresponding with it, and the data statistics process of electronization substantially increases the accuracy of detection architecture.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, content of the present utility model is described further:
Fig. 1 is structural representation of the present utility model.
Reference numeral: hammer body 1, hammer handle 2, pressure transducer 3, manual time-keeping parts 4, LCDs 5, contact arm 6, spongy body 7, pressure-sensitive switch 8, power supply unit 9.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain this utility model, protection domain of the present utility model can not be limited with this.
Structural representation of the present utility model is given in accompanying drawing 1, a kind of electronic nerve detection hammer, comprising: hammer body 1, hammer handle 2, pressure transducer 3, manual time-keeping parts 4, LCDs 5, contact arm 6, spongy body 7, pressure-sensitive switch 8, power supply unit 9.
Wherein, hammer body 1 is rubber hammer, increases the comfort level of knocking patient, avoids causing damage to the knee of patient.
It is inner that pressure transducer 3 is positioned at the front end that hammer body 1 contacts with patient's knee, can the percussion power that bears of instantaneous induction patient knee, and by internal wiring, pressure signal is passed to manual time-keeping parts 4 and LCDs 5 respectively.
Manual time-keeping parts 4 and LCDs 5 are positioned at the side of hammer handle 2 front end.Manual time-keeping parts 4 are high accuracy timer second, and precision is being 0.001 second, and it just starts clocking capability after receiving the pressure signal that pressure transducer 3 sends here at once; And when receiving the stop signal that pressure-sensitive switch 8 is sent here, just stop timing at once.
LCDs 5, except display timing second change procedure, also finally can demonstrate percussion power angle value and knee jerk time value that patient's knee bears.
Contact arm 6 is positioned in the middle part of hammer handle 2, and parallel with hammer body 1 homonymy, its length is less than hammer body 1 length.
Spongy body 7 is positioned at contact arm 6 front end, in order to cushion impact force when contacting with contact arm 6 when patient's shank raises up.
It is inner that pressure-sensitive switch 8 is positioned at spongy body 7, after it senses impact force, automatically can produce stop signal, and pass to manual time-keeping parts 4.
Power supply unit 9 is built-in rechargeable battery, for pressure transducer 3, manual time-keeping parts 4, LCDs 5 and each electronic unit of pressure-sensitive switch 8 provide power supply.Certainly, power supply unit 9 here also can adopt external detachable battery.
In the middle of concrete use, medical worker holds hammer handle 2 rear end, and the knee by hammer body 1 couple of patient beats; The pressure transducer 3 of inside, hammer body 1 front end induces the percussion power that patient's knee bears, and is converted into electric pressure signal, passes to manual time-keeping parts 4 and LCDs 5 respectively; Manual time-keeping parts 4 start timing second, and LCDs 5 demonstrates the percussion power angle value and timing second change procedure that patient's knee bears; Until the shank of patient raises up, touch the pressure-sensitive switch 8 of spongy body 7 inside, contact arm 6 front end; After pressure-sensitive switch 8 senses impact force, automatically can produce stop signal, and pass to manual time-keeping parts 4; After manual time-keeping parts 4 receive stop signal, just stop timing at once, and in LCDs 5, finally demonstrate the percussion power angle value that patient's knee bears and the knee jerk time value counted.This Tool integration tradition percussion hammer and manual time-keeping device are integrated, and effectively reduce the work trouble of medical worker, improve work efficiency, medical worker easily draws electronic testing result in the middle of LCDs 5, accurately and reliably.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, one of ordinary skill in the art will be recognized, use scheme of the present utility model can also realize many optional embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
