Specific embodiment

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.

As shown in Figure 1, the utility model provides a kind of medical pupil measuring device, including penholder 100.The penholder 100 End be equipped with headlamp 200, the tail portion of the penholder 100 be equipped with push switch 300 control the headlamp 200 opening or Person closes, and battery is equipped in the penholder 100 as the headlamp 200 power supply.The side wall of the penholder 100 offers sliding slot 110, the sliding slot 110 is distributed adjacent to the headlamp 200.Being equipped in the sliding slot 110 can move back and forth along the sliding slot 110 Dynamic connecting shaft 400, axis connection has movable first support arm 500 and second support arm 600, and activity in the connecting shaft 400 First support arm 500 and second support arm 600 upper end surface in same plane.The first support arm 500 and the second support arm 600 inner sidewall offers multiple pupils for extending transversely through first support arm 500 or second support arm 600 than device to hole 700, is located at Pupil in the first support arm 500 and second support arm 600 is equally intervally arranged than device to hole 700, and each pupil The aperture of boring ratio device to hole 700 is different, and each pupil is equipped with aperture mark 710 than the lower section of device to hole 700.

Using the above structure, push switch 300 is pressed, headlamp 200 lights, and can irradiate eye in eyeball upper vertical Ball.The first support arm 500 of axis connection and second support arm 600 are opened, first support arm 500 and second support arm 600 is kept to form one Straight line is located at the rear of headlamp 200, and the end face that penholder 100 does not set sliding slot 110 is held in front, irradiates eyeball at this time, the One support arm 500 and second support arm 600 can be located at below eyelid, extend transversely through the pupil ratio of first support arm 500 and second support arm 600 Device to hole 700 is carried out using the pupil of different pore size in first support arm 500 and second support arm 600 than device to hole 700 towards medical staff It compares, then obtains pupil size.When not needing to carry out pupil comparison, first support arm 500 and the closure of second support arm 600 are received It receives.The position of adjustable connecting shaft 400 when eyeball is irradiated in the movable movement in sliding slot 110 of connecting shaft 400, drives first Support arm 500 and second support arm 600 are fixed close to the either separate headlamp 200 of headlamp 200 with finger.This pupillometry Device can reduce comparison time, can be judged in time, keep to compare repeatedly under the premise of irradiation posture is constant, improve and survey The accuracy of amount.Even if there is critical patient, do not need other people and assist, eyelid is moved in one handspring of medical staff, a hand into Row irradiation compares, and also can be carried out pupillometry and obtains numerical value.

As one of optional embodiment, cylindrical fixed column 800 is fixedly provided in the sliding slot 110, and be distributed In in this end sliding slot 110 of the neighbouring push switch 300.It is embedded with magnet annulus 810 on the side wall of the fixed column 800, The inner sidewall of the first support arm 500 and the second support arm 600 respectively offers an arc-shaped bayonet 510 and the fixed column 800 clampings.The bayonet 510 extends vertically through the first support arm 500 or second support arm 600, and embedding in this 510 inner wall of bayonet It is adsorbed equipped with magnet block 511 and 810 phase of magnet annulus in the fixed column 800.First support arm 500 and second are not being used It when arm 600, avoids connecting shaft 400 mobile to drive first support arm 500 and 600 activity of second support arm to make troubles, utilizes the Bayonet 510 on one support arm 500 and second support arm 600 is respectively engaged with the left and right sides of fixed column 800, passes through magnetic after clamping The absorption of iron annulus 810 and magnet block 511 is fixedly secured first support arm 500 and second support arm 600.To use first support arm 500 When with second support arm 600, first support arm 500 and second support arm 600 are removed from fixed column 800, is adjusted using connecting shaft 400 Measurement can be compared in position.

The top surface of the connecting shaft 400 and the top surface of the fixed column 800 are connected with the upright bar 900 of vertical distribution, Telescopic rod 910 is equipped between two upright bars 900.Telescopic rod 910 is adjusted, connecting shaft 400 can be driven mobile, so as to adjust simultaneously The position of fixed connection shaft 400, it is no longer necessary to which manual fixed connection shaft 400 is more convenient to use.And work as 500 He of first support arm Second support arm 600 in opened condition when, finger can be inserted in the gap between telescopic rod 910 and penholder 100, can work It is middle to improve the stability for holding penholder 100.

First support arm 500 and the second support arm 600 are all made of transparent plastic material and are made, and the first support arm 500 and the second support arm 600 at least four pupils are respectively distributed with than device to hole 700, the adjacent pupil of every two than device to hole 700 it Between spacing be 1mm, be convenient for matching measurement.

100 top of penholder is also equipped with lanyard 120, can hang this pupil measuring device, or hang over key chain On carry.

The above is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all benefits The equivalent structure made by the utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks Domain, similarly within the scope of patent protection of the utility model.
