Designed by said structure, in this utility model, slide assemblies can relative to device case translation, and by the measurement of angular transducer to the anglec of rotation of the driving rotating disk in driven unit, the change of slide assemblies translational speed can be detected, then real-time intraocular pressure is calculated by the analyzing and processing of processor, this utility model calculates intraocular pressure value by electronic surveying, electronics, and its data measured are reliable, simple and easy to use.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of hand-held resilience tonometer in a kind of embodiment of this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Please refer to Fig. 1, Fig. 1 is the structural representation of hand-held resilience tonometer in a kind of embodiment of this utility model.
This utility model provides a kind of hand-held resilience tonometer, comprising: device case 1, and the front end of device case 1 has been mounted slidably slide assemblies 2, slide assemblies 2 is provided with eye socket bracing frame 3 and the probe 4 for contacting with cornea; Driven unit, driven unit includes screw rod 5, the driving rotating disk 6 be threaded with screw rod 5 and the driver part for rotating drive rotating disk 6, screw rod 5 is fixed with device case 1, and drive rotating disk 6 to be arranged on slide assemblies 2 rotationally, driver part is arranged on slide assemblies 2; Detection system, detection system includes the processor 7 with logical analysis function and is connected with processor 7 signal for detecting the angular transducer 8 driving rotating disk 6 anglec of rotation, and angular transducer 8 is connected with driving rotating disk 6.
In said structure design, slide assemblies 2 can relative to device case 1 translation, the movement of slide assemblies 2 is realized by driven unit, this utility model additionally provides detection system, by the measurement of the anglec of rotation of the driving rotating disk 6 in angular transducer 8 pairs of driven units, the change of slide assemblies 2 translational speed can be detected, then calculate real-time intraocular pressure by the analyzing and processing of processor 7.This utility model calculates intraocular pressure value by electronic surveying, electronics, and its data measured are reliable, simple and easy to use.
It should be noted that: when screw rod 5 is fixedly installed on device case 1, with device case 1 for reference, during rotary actuation rotating disk 6, drive rotating disk 6 can move on screw rod 5, because on screw rod 5, pitch is identical, then drive the rotary speed of rotating disk 6, angle and the translational speed of driving rotating disk 6 on screw rod 5, displacement direct proportionality, therefore, this utility model have employed angular transducer 8 and measures driving the anglec of rotation of rotating disk 6, then combine and rotate the time used, the angular velocity of rotation and displacement that drive rotating disk 6 can be accurately measured, thus calculate translational speed and the displacement of probe 4, analysis through processor 7 draws real-time intraocular pressure.
In a specific embodiment of the present utility model, probe is fixed on slide assemblies 2, and it is parallel with the angular transducer 8 on processor 7, governor motion i.e. driven unit, mainly regulated the length of slide assemblies 2 by adjusting nut, make the probe 4 that slide assemblies 2 is arranged reach required separation distance with cornea, and ensure that probe 4 is vertical with anterior corneal surface, and then can precise information be obtained, add the reliability and accuracy that collect data.
In order to improve the comfortableness that this utility model uses, probe 4 is cylindrical structural, and one end of probe 4 is connected with slide assemblies 2, and the other end of probe 4 is the contact head of smooth arc shape.
