Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to an intelligent pupil measurement device. Background Technology

[0002] The core purpose of pupil examination is to assess the physiological structure and functional status of the eye by observing indicators such as pupil size, shape, light reflex, and accommodation function, and to assist in the diagnosis of eye diseases (such as glaucoma, optic nerve disease, iris injury, etc.). At the same time, it can indirectly reflect the health status of multiple organs in the body, such as the central nervous system and cardiovascular system. In clinical physical examination, ophthalmological diagnosis and treatment, craniocerebral injury assessment, anesthesia monitoring, and forensic identification, it provides important objective evidence for disease screening, condition assessment, and efficacy monitoring.

[0003] In the pupil detection process of clinical diagnosis and treatment, the detection principle of existing pupil measurement devices is mostly based on optical imaging or infrared sensing technology. The detection process requires that the device probe and the pupil being measured be directly opposite each other, and the pupil area must be completely exposed in the detection field of view.

[0004] In emergency trauma treatment and postoperative eye rehabilitation, some patients experience eyelid swelling. The swollen eyelid tissue can easily obstruct the pupil and restrict the degree of eyelid opening and closing. In this situation, existing devices cannot achieve precise alignment between the probe and the pupil. If the eyelid is pulled by external force to expose the pupil, it can easily cause secondary damage to the patient, resulting in low detection efficiency and insufficient accuracy of measurement data.

[0005] To address this issue, an intelligent pupil measurement device is proposed. Summary of the Invention

[0009] Preferably, the head fixing assembly includes a fixing ring fixedly connected to the lower end of the lifting plate. Threaded pins are threaded to both sides of the fixing ring. An arc-shaped clamping plate is rotatably connected to one end of each of the two threaded pins.

[0011] Preferably, the swelling reduction component includes a movable seat fixedly connected to the end of one of the horizontal plates. Two placement slots are formed on the front sidewall of the movable seat, and multiple miniature electric push rods are fixedly connected to the inner wall of each placement slot. The output ends of each miniature electric push rod are connected to a cooling plate, and a thin-film pressure sensor is connected to the sidewall of the cooling plate. A delivery pipe is inserted inside the cooling plate, and a common flexible hose connects adjacent delivery pipes. A delivery cavity is formed inside the movable seat, and a water tank is connected to the lower inner wall of the delivery cavity. Multiple small semiconductor refrigeration plates are inserted into the sidewall of the water tank. The cooling end of each small semiconductor refrigeration plate is located inside the water tank and in contact with the cooling water, while the heat-releasing end of the small semiconductor refrigeration plate extends out of the water tank. A small water pump is connected to the sidewall of the water tank, and the outlet of the small water pump is connected to one of the delivery pipes via a flexible hose. The uppermost delivery pipe is connected to a return water pipe via a flexible hose, and the lower end of the return water pipe is connected to the upper sidewall of the water tank.

[0012] Preferably, the irradiation assembly includes a guide rail fixedly connected to the end of another horizontal plate. Two movable blocks are slidably disposed on the surface of the guide rail. A connecting pin is connected to the front sidewall of each of the two movable blocks. A rubber cover is fixedly connected to the lower end of the connecting pin.

[0013] Preferably, the inner wall of the conveying cavity is connected to a fan located above a small semiconductor cooling plate, and the side wall of the conveying cavity is provided with multiple heat dissipation holes.

A horizontal moving cylinder is slidably sleeved outside each of the two horizontal pins. The sidewall of the opposite side of the two horizontal moving cylinders on the same side is fixedly connected with the same perforated plate. Multiple LED beads are distributed in a ring on the surface of the perforated plate.

[0015] Compared with existing technologies, the advantages of an intelligent pupil measurement device are: 1. By using a head fixation component and a swelling reduction component, before measuring the pupil of a patient with swollen eyelids, low-temperature stimulation causes the subcutaneous capillaries of the eyelids to constrict, reducing local blood flow and tissue fluid exudation. This quickly reduces the degree of eyelid swelling, increasing the pupil exposure range and reducing the difficulty of measurement operations caused by eyelid obstruction. At the same time, low temperature can inhibit the sensitivity of local nerve endings, relieving the swelling and discomfort caused by eyelid swelling, and preventing limb abnormalities due to pain during the subsequent eyelid opening operation for pupil measurement, thus improving the stability and data accuracy of the testing process. In addition, ice application can also reduce the inflammatory response of eyelid tissues to a certain extent, reducing the risk of skin and mucous membrane damage or secondary edema caused by external force when opening the eyelids.

[0016] 2. Using the irradiation components, for patients with swollen eyelids that have been reduced by ice packs, pupil size and light reflex can be observed by irradiating the eyelids. This eliminates the need to forcibly open the eyelids; the light penetrates the thinned, swollen eyelid tissue and acts directly on the pupil. This avoids secondary damage to the eyelids caused by external traction, alleviates patient discomfort during testing, and minimizes interference with the natural state of the pupil from eyelid opening and closing, ensuring the accuracy of baseline pupil size data. Simultaneously, the pupil's contraction and dilation changes can be observed in real time during irradiation, clearly capturing the sensitivity of the light reflex and providing stable and reliable objective evidence for clinical diagnosis.

[0017] 3. The head fixation component stabilizes the patient's head during pupil measurement, maintaining a stable head and eye posture. This prevents changes in the relative position of the measuring probe and pupil due to head movement or body position shift, ensuring that the measuring light or detection field of view remains aligned with the pupil area. This improves the accuracy and repeatability of measurements such as pupil size and light reflection. Furthermore, it reduces the risk of accidental probe contact with the eyelids due to patient head movement, minimizing eye discomfort and the risk of secondary injury, and ensuring a smooth and orderly testing procedure.

Two limiting holes matching the limiting pins 14 are provided on the sidewall of the fixing ring 121. A rotating ring 15 is rotatably connected to the outer wall of the fixing ring 121 via a resistance bearing. The outer wall of the rotating ring 15 is connected to the swelling reduction component 20 and the irradiation component 31 respectively via two positioning components 16.

One end of the two horizontal plates 19 extending out of the horizontal cylinder 18 is connected to the swelling reduction component 20 and the irradiation component 31, respectively. A support seat 6 is connected to the upper side wall of the base plate 1. A pad ring 7 located below the head fixation component 12 is fixedly connected to the upper side wall of the support seat 6. The swelling reduction component 20 and the irradiation component 31 are provided on the outside of the head fixation component 12.

[0022] The swelling reduction component 20 includes a movable base 201 fixedly connected to the end of one of the horizontal plates 19. Two placement slots 202 are formed on the front side wall of the movable base 201, and multiple miniature electric push rods 21 are fixedly connected to the inner wall of each placement slot 202. The output ends of each miniature electric push rod 21 are connected to a cooling plate 22, and a thin-film pressure sensor 42 is connected to the side wall of the cooling plate 22. A delivery pipe 23 is inserted inside the cooling plate 22, and a common flexible tube 24 connects adjacent delivery pipes 23. A delivery cavity 25 is formed inside the movable base 201, and a water tank 26 is connected to the lower inner wall of the delivery cavity 25. Multiple small semiconductor cooling plates 27 are inserted into the side wall of the water tank 26. The inner wall of the delivery chamber 25 is connected to a fan 35 located above the small semiconductor cooling plate 27. The side wall of the delivery chamber 25 is provided with multiple heat dissipation holes. The cooling end of the small semiconductor cooling plate 27 is located in the water tank 26 and is in contact with the cooling water. The heat dissipation end of the small semiconductor cooling plate 27 extends out of the water tank 26. The side wall of the water tank 26 is connected to a small water pump 28. The outlet end of the small water pump 28 is connected to one of the delivery pipes 23 through a hose 24. The uppermost delivery pipe 23 is connected to a return water pipe 29 through a hose 24.

The trigger switch 30 is electrically connected to the controller 3.

[0023] The irradiation assembly 31 includes a guide rail 311 fixedly connected to the end of another horizontal plate 19. Two moving blocks 312 are slidably disposed on the surface of the guide rail 311. Connecting pins 32 are connected to the front sidewalls of the two moving blocks 312. A rubber cover 33 is fixedly connected to the lower end of the connecting pin 32. An irradiation light source 34 is connected to the inner wall of the rubber cover 33.

[0024] Two guide pins 36 are symmetrically fixedly connected to the upper sidewall of the base plate 1. A movable cylinder 37 is slidably disposed outside each of the two guide pins 36. The movable cylinder 37 is fixed by positioning bolts and guide pins 36. Two horizontal pins 38 are fixedly connected to the sidewall of the opposite side of the two movable cylinders 37. A horizontal moving cylinder 39 is slidably sleeved outside each of the two horizontal pins 38. The same perforated plate 40 is fixedly connected to the sidewall of the opposite side of the two horizontal moving cylinders 39 on the same side. Multiple LED beads 41 are distributed in a ring on the surface of the perforated plate 40. When measuring the pupil of a normal patient, the movable cylinder 37 drives the perforated plate 40 to move upward to a suitable height, and the two perforated plates 40 are moved horizontally (in the initial state, the perforated plates 40 are located on both sides respectively) to align the perforated plate 40 with the patient's eye. Then, the LED beads 41 distributed in a ring on the surface of the perforated plate 40 are turned on, and the reaction of the patient's pupil to the light of the LED beads 41 is detected by the detection probe 4.

[0025] The operating principle of the present invention is explained as follows: Medical staff place the device in a suitable position, then guide the patient to sit in front of the base plate 1 and place their chin on the pad ring 7. Next, the medical staff rotates the rotating handle 9, which drives the threaded cylinder 82 to rotate. Through the threaded engagement, the threaded rod 10 moves. The threaded rod 10 drives the fixing ring 121 to move downward around the patient's head through the lifting plate 11. Then, the medical staff manually rotates the threaded pins 122 on both sides. Through the threaded engagement between the threaded pins 122 and the threaded holes on the surface of the fixing ring 121, the threaded pins 122 will drive the arc-shaped clamping plate 13 to move towards the direction of the patient's head. The patient's head is fixed by the two arc-shaped clamping plates 13. When a patient has difficulty opening their eyes due to eyelid swelling caused by trauma or other reasons, medical staff rotate the rotating ring 15 at a certain angle to position the swelling reduction component 20 in front of the patient's face. Then, the medical staff pulls the vertical pin 17 in front of the patient down to a suitable position and fixes it with positioning bolts to align the multiple cooling plates 22 on the surface of the moving seat 201 with the patient's eyelids. Next, the medical staff pulls the moving seat 201 closer to the patient's face. When the trigger switch 30 on the surface of the moving seat 201 contacts the patient's brow, the trigger switch 30 sends an electrical signal to the controller 3. After receiving the electrical signal, the controller 3 controls its own buzzer module to emit a prompt sound. After hearing the prompt sound, the medical staff can release the moving seat 201 and fix the horizontal plate 19 on the side with positioning bolts. Next, medical staff send an electrical signal to controller 3 via an external switch. Upon receiving the signal, controller 3 simultaneously controls multiple miniature electric actuators 21 in the two placement slots 202. These actuators move the cooling plate 22 and the thin-film pressure sensor 42 closer to the patient's swollen eyelid. When controller 3 detects that the cooling plate 22, along with the thin-film pressure sensor 42, is in contact with the patient's eyelid and maintaining a pressure of 0.2N, it stops the miniature electric actuators 21. This process, by having multiple miniature electric actuators 21 bring multiple cooling plates 22 and thin-film pressure sensors 42 into contact with the patient's swollen eyelid, ensures that the cooling plates 22 fully contact the swollen area. The eyelids are then fitted together, and the controller 3 controls the small semiconductor cooling plate 27 and the small water pump 28 to work. The small semiconductor cooling plate 27 cools the coolant inside the water tank 26, and the small water pump 28 delivers the cooled coolant through the hose 24 to multiple delivery pipes 23. The coolant will lower the temperature of the cooling plate 22, and the coolant that has absorbed heat will flow back to the water tank 26 through the return pipe 29. When the patient's eyelids have cooled down and the swelling has subsided for about 10 minutes, a certain degree of swelling reduction effect will be achieved. After the controller 3 detects that the pressure between the cooling plate 22 and the eyelid is less than 0.1N through the thin film pressure sensor 42, it will control its own buzzer module to emit a prompt sound. After hearing the prompt tone, medical staff can move the movable seat 201 away from the patient and rotate the rotating ring 15 to move the irradiation component 31 in front of the patient. Following the principle described above, the positioning component 16 is adjusted so that the two rubber covers 33 irradiate the patient's swollen eyelids (medical staff need to manually and gently lift the patient's eyelids to a certain extent and slightly squeeze them with the rubber covers 33 to keep the eyelids slightly open). Then, the medical staff controls the irradiation light source 34 inside the rubber cover 33 through the controller 3, so that the light beam emitted by the irradiation light source 34 passes through the eyelids and reaches the pupil. The size of the pupil and the light reaction are detected by the detection probe 4 on the surface of the detector 2 and automatically recorded.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
