4. the testing and measuring technology when using is comparatively complicated.
Do not see yet in the market, overcome the applanation tonometer of above defective.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, provide never see on a kind of market can overcome these defectives, practical, the well behaved slit lamp microscopic system of function.
Following technical proposals is adopted in this practicality:
System forms and comprises gage outfit 1, measurement connecting rod 2, fork 3, swinging axle 4, the gimbal lever 5, swing arm 6, spring 7, tooth bar 8, gear 16, gear shaft 9, knob 10, housing supports device 17 compositions; It is characterized in that; Also be provided with elastic part 11, foil gauge 12 and foil gauge and measure display device 13; Said elastic part 11 two ends are fixedly connected between said measurement connecting rod 2 and the swinging axle 4; Said foil gauge 12 is fixedly connected on the said elastic part 11, and said foil gauge 12 can also be done with said foil gauge measurement display device 13 and be electrically connected, to show the measurement result of said foil gauge 12.
Said foil gauge is measured display device 13 and can be arranged on the said housing supports device 17.
Can also be provided with potentiometer 14, potentiometer measurement display device 15; The rotation position of said potentiometer 14 is fixedly connected on the said gear shaft 9; Said potentiometer 14 can also be done with said potentiometer measurement display device 15 and be electrically connected, to show the measurement result of said potentiometer 14.
Said potentiometer is measured display device 15 and can be arranged on the said housing supports device 17.
The advantage of this utility model is:
1. will adopt pick off to carry out data acquisition, the circuit in said foil gauge is measured display device or said potentiometer measurement display device carries out analog digital conversion, amplification, computing, at last measured value is clearly illustrated out.
2. as long as through changing the sensitivity that different ground sensor element just can improve measurement like a cork.
3. an elastic part directly is connected with the measurement connecting rod, and foil gauge is affixed on the elastic part, has reduced the measurement transmission link, can farthest reduce measurement error.
4. adopt the sensor acquisition measurement data, so less demanding to the internal balance of system.
5. the assembly technology difficulty will reduce greatly, enhances productivity, and reduces the production cost.

Fig. 2 is the sketch map of swing transmission mechanism, among Fig. 2: fork 3, swinging axle 4, the gimbal lever 5, swing arm 6, spring 7, tooth bar 8, gear 16, gear shaft 9.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done further detailed description:
System forms and comprises gage outfit 1, measurement connecting rod 2, fork 3, swinging axle 4, the gimbal lever 5, swing arm 6, spring 7, tooth bar 8, gear 16, gear shaft 9, knob 10, housing supports device 17 compositions; It is characterized in that; Also be provided with elastic part 11, foil gauge 12 and foil gauge and measure display device 13; Said elastic part 11 two ends are fixedly connected on to be measured between connecting rod 2 and the swinging axle 3; Said foil gauge 12 is fixedly connected on the said elastic part 11, and said foil gauge 12 can also be done with said foil gauge measurement display device 13 and be electrically connected, to show the measurement result of said foil gauge 12.
Said foil gauge is measured display device 13 and can be arranged on the said housing supports device 17.
Can also be provided with potentiometer 14, potentiometer measurement display device 15; The rotation position of said potentiometer 14 is fixedly connected on the said gear shaft 9; Said potentiometer 14 can also be done with said potentiometer measurement display device 15 and be electrically connected, to show the measurement result of said potentiometer 14.
Said potentiometer is measured display device 15 and can be arranged on the said housing supports device 17.
Among Fig. 1,2, make said measurement connecting rod 2 stand on vertical position with said gage outfit 1 through regulating naturally of the said gimbal lever 5.When measuring, earlier through the said knob 10 of rotation, said gage outfit 1 is tilted towards the measured direction, impact to guarantee that said gage outfit 1 can not produce the cornea of the measured when measuring.Rotate said knob 10 said gear shaft 9 is rotated, the said gear 16 on the said gear shaft 9 drives said tooth bar 8 and moves, and said tooth bar 8 is pushing away said swing arm 6 again and moving, thereby drives said fork 3, and said fork 3 is rotated around said swinging axle 4.Said elastic part 11, measure connecting rod 2, gage outfit 1, thereby make said gage outfit 1 flatten cornea together along with said swinging axle 4 rotates.Through the outside slit lamp microscope observation of tonometer, can judge that cornea just in time is driven plain.This moment, said foil gauge 12 extracted the deflection of said elastic part 11, measured amplification, analog digital conversion, the calculating of display device 13 again through said foil gauge, drew measurement result then, and showed.As long as it has been exactly the actual intraocular pressure value that records that the doctor reads the measurement result of said foil gauge measurement display device 13.
If what adopt is said potentiometer 14; As long as measure angle or change in resistance amount that said knob 10 turns over so; And measure amplification, analog digital conversion, the calculating of display device 15 through said potentiometer, draw measurement result then, and directly show the actual intraocular pressure value that records.
