Abstract
The utility model discloses a holding power measurement device which is used for measuring the holding power and is especially applied to an upper limb rehabilitation robot in medical rehabilitation. The device comprises four parts including a holding contact surface, a bracket, a knob and a sensor. According to the device, a holding power measurement function can be achieved, the measurement sensitivity and precision are improved, the error cannot be increased after the device is used for a long time, and the reliability is high.
Description
Technical field
this utility model relates to a kind of device that is applied in the measurement grip in medical apparatus and instruments, relates in particular to a kind of device of Measurement accuracy grip.
Background technology
the instrument of the current measurement grip of using in industry at present, mainly applies resistance strain gage sensor, and wherein resistance strain gage is main ingredient.Resistance strain gage application is maximum is two kinds of metal resistance strain gauge and semiconductor gauges, bonding closely by special bonding agent, producing on mechanics strain matrix, when the stressed generation STRESS VARIATION of matrix, resistance strain gage also produces deformation together, and the resistance of foil gauge is changed, thereby make to be added in ohmically voltage, changes, to obtain measuring-signal, finally reach the object of measuring grip size.But resistance strain gage life-time service or overexertion use can cause deformation excessively to cause being reduced into original state, thereby cause the instrumental sensitivity of measuring grip to reduce, measure grip numerical value inaccurate, long-time use error is larger.
Summary of the invention
for above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide one to put forward high measurement sensitivity and precision, and use error can not increase for a long time, the device of the measurement grip that reliability is high.
for achieving the above object, this utility model adopts following technical scheme:
measure a device for grip, comprise and hold contact surface, support, knob, four parts of sensor, support is connected with knob, is provided with sensor in support, and described sensor is gas sensor, preferably semiconductor gas sensor
the wherein said contact surface material therefor of holding is a kind of elastically-deformable material, is subject to External Force Acting and relative position between each point is changed, and after external force is cancelled, solid restores to the original state again, is preferably silica gel.Holding contact surface can be irregular formation, is preferably cylinder.Support is passive, bears larger power, also has positioning action, and making to keep correct position, support between part is ordinary stent, can belong to any material, and support is simultaneously according to and then corresponding variation of variation of holding contact surface.
wherein said sensor is a kind of detecting instrument, can experience measured information, and the information that detection can be experienced, be for conversion into according to certain rules the information output of the signal of telecommunication or other desired forms, described sensor is gas sensor, preferably semiconductor transducer.
wherein said knob Main Function is to be connected with support holding contact surface, and the medical apparatus and instruments that the other end is also analyzed with upper limb robot or other data that can collect detection is simultaneously connected.
hold and tightly hold contact surface, make to hold contact surface and produce deformation, hold contact surface inner volume and change, gas is from internal stent flow direction sensor, sensor is produced to pressure, and sensor carries out data acquisition and output, finally changes into the signal of telecommunication and carries out data analysis and output to terminal.
as mentioned above, this utility model can be realized the function of measuring grip, and then puies forward high measurement sensitivity and precision, and long-time use error can not increase, the device of the measurement grip that reliability is high.
Accompanying drawing explanation
fig. 1 is the axonometric chart of a kind of a kind of embodiment of device that measures grip of this utility model
fig. 2 is Fig. 1 profile
wherein: 1, silica gel sheath; 2, knob; 3, support; 4, gas sensor; 5, conduit; 6, aperture.
The specific embodiment
below in conjunction with accompanying drawing and the specific embodiment, this utility model is described further:
refer to Fig. 1 to Fig. 2, this utility model provides a kind of device of measuring grip, be used for putting forward high measurement sensitivity and precision, long-time use error can not increase, the device of the measurement grip that reliability is high, the support 3 of the device of this measurement grip is enclosed in silica gel sheath 1 completely and joins with knob 2, and has gas sensor 4 in support 3.Holding silica gel sheath 1 and exerting all one's strength, make silica gel sheath 1 produce deformation, silica gel sheath 1 inner volume changes, gas flows to gas sensor 4 from aperture 6 through conduit 5, gas sensor 4 is produced to pressure, gas sensor 4 carries out data acquisition and output, finally changes into the signal of telecommunication and carries out data analysis and output to terminal.
as mentioned above, this utility model is measured the function of grip by realizing, and then puies forward high measurement sensitivity and precision, and long-time use error can not increase, the device of the measurement grip that reliability is high.
to one skilled in the art, can be according to technical scheme described above and design, make other various corresponding changes and deformation, and within these all changes and deformation all should belong to the protection domain of this utility model claim.
