Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the pupil pen includes a pen holder 1 and an illuminating lamp 2, wherein the illuminating lamp 2 is disposed at one end of the pen holder 1. When the pupil diameter is measured by the pupil pen, the light of the illuminating lamp 2 is emitted to the pupil of a patient, and the pupil diameter is obtained by the doctor through subjective judgment.

Therefore, in order to improve the accuracy of the obtained pupil diameter, the transparent film 4 is arranged on the outer side of the lampshade of the illuminating lamp 2, and the transparent film 4 is marked with scales, so that when the illuminating lamp 2 is turned on, the light of the illuminating lamp 2 irradiates the transparent film 4 of the lampshade, the scales of the transparent film 4 are projected to the pupil of the patient, the scales are displayed at the pupil of the patient, and at the moment, a doctor can directly read the scales corresponding to the pupil diameter of the patient, so that the error of the pupil diameter obtained by artificial judgment is reduced.

Illustratively, referring to fig. 2, the scale of the transparent film 4 may be as shown in fig. 2, since the size of the pupil diameter of a person is in the range of 2.5mm-5mm, the total number of the scales of the transparent film 4 is 4 circles, and the diameters of the circles from small to large are 2mm, 3mm, 4mm and 5mm, respectively, and the doctor only needs to determine the number of circles when reading the scale, for example: assuming that the circle of minimum diameter is the first circle, the doctor reads the scale as the first circle, and the size of the pupil diameter of the patient is 2 mm.

As the distance between the pupil pen and the patient's pupil changes, there will also be a change in the scale displayed at the patient's pupil, for example: assuming that the diameter of the pupil of the patient is 3mm, when the distance between the pupil pen and the pupil of the patient is 10cm, the scale displayed at the pupil of the patient is 3mm, and when the distance between the pupil pen and the pupil of the patient is 20cm, the scale displayed at the pupil of the patient is 2 mm.

Therefore, in order to avoid the above situation, the distance between the pupil pen and the pupil of the patient needs to be fixed, therefore, the first rotating rod 3 is provided in the invention, the first rotating rod 3 is rotatably connected to the outer wall of the pen holder 1, and the length of the first rotating rod 3 is set to have a corresponding relation with the scale of the transparent film 4.

There are two states of the first turning lever 3, with continued reference to fig. 1, the first turning lever 3 is in a stowed state, with reference to fig. 3, the first turning lever 3 is in an extended state.

When the pupil diameter of a patient needs to be measured, the first rotating rod 3 is in an extending state, so that the distance between the pupil of the patient and the pupil pen is fixed, and the measuring accuracy is ensured.

With continued reference to fig. 1, the illuminating lamp can further comprise a first rotating shaft 5, one end of the first rotating shaft 5 is fixedly connected to the outer wall of the penholder 1 close to the illuminating lamp 2, and the other end of the first rotating shaft 5 is rotatably connected with the first rotating rod 3. Through designing first pivot 5, realized that first rotation pole 3 rotates to be connected in the outer wall of pen-holder 1.

For example, the first rotating shaft 5 may be fixedly connected to the outer wall of the barrel 1 by being integrally formed with the barrel 1, or by being welded to the outer wall of the barrel 1, which is not limited in this disclosure.

With continued reference to fig. 1, a first protection pad 6 may be further included, and the first protection pad 6 is disposed at an end of the first rotating rod 3 away from the first rotating shaft 5. The design of this first protection pad 6 makes the eye that contacts the patient softer, avoids stabbing the patient.

Referring to fig. 4, a second rotating rod 7 may be further included, the second rotating rod 7 is rotatably connected to the outer wall of the barrel 1, and the length of the second rotating rod 7 is the same as that of the first rotating rod 3. This design of second dwang 7 can realize guaranteeing jointly through first dwang 3 and second dwang 7 that the distance between patient's pupil and the pupil pen is fixed, when first dwang 3 breaks down, only can still guarantee through second dwang 7 that the distance between patient's pupil and the pupil pen is fixed simultaneously, guarantees the normal use of pupil pen.

Continuing to refer to fig. 4, a second rotating shaft 8 may be further included, one end of the second rotating shaft 8 is fixedly connected to the outer wall of the penholder 1 close to the illuminating lamp 2, and the other end is rotatably connected to the second rotating rod 7. Through designing second pivot 8, realized that second dwang 7 rotates to be connected in the outer wall of pen-holder 1.

For example, the second rotating shaft 8 may be fixedly connected to the outer wall of the barrel 1 by being integrally formed with the barrel 1, or by being welded to the outer wall of the barrel 1, which is not limited in this disclosure.

With continued reference to fig. 4, a second protection pad 9 may be further included, and a second protection pad 9 is disposed at an end of the second rotating rod 7 away from the second rotating shaft 8. The design of this second protection pad 9 makes the eyes that contact the patient softer, avoids stabbing the patient.

Continuing to refer to fig. 1, the pen may further include a lamp switch 10 and a battery, the lamp switch 10 is disposed at the other end of the pen holder 1, the battery is disposed in the pen holder 1, the lamp switch 10 is electrically connected to the battery, and the battery is electrically connected to the lamp 2. The lamp switch 10 is designed to effectively control the lamp 2 to be turned on and off, and the battery is designed to effectively supply power to the lamp 2.

With continued reference to fig. 1, the outer wall of the pen holder 1 is transversely and integrally formed with a pen clip. The design can more effectively help a doctor to store and hold the pupil pen.

Illustratively, the barrel 1 may be made of stainless steel.

The working principle is as follows: when a doctor uses the pupil pen to measure the pupil diameter, the doctor firstly presses the lighting lamp switch 10, so that the light of the lighting lamp 2 irradiates on the transparent film 4 of the lampshade, and the scales of the transparent film 4 are projected to the pupil of the patient, at the moment, the doctor can directly read out the scales corresponding to the pupil diameter of the patient, and therefore, the error of manually judging the obtained pupil diameter is reduced.

To sum up, this pupil pen through the design of pen-holder, light, first rotation pole and transparent film, has effectually realized that this pupil pen can help the doctor to carry out the effect of accurate measurement pupil diameter, has effectively solved the lower problem of the pupil diameter's that original doctor obtained through subjective judgement accuracy. This pupil pen, through the design of first protection pad 6, can be so that pupil pen contact patient's eye is softer, avoids stabbing the patient. Through the design of second dwang 7, can realize guaranteeing jointly through first dwang 3 and second dwang 7 that the distance between patient's pupil and the pupil pen is fixed, when first dwang 3 breaks down, only can still guarantee through second dwang 7 that the distance between patient's pupil and the pupil pen is fixed simultaneously, guarantees the normal use of pupil pen. Through the design of the pen clip, when the pupil pen is not used by a doctor, the whole pupil pen can be effectively hung in the pocket, and the pupil pen is convenient for the doctor to take and use.
