An intraocular tonometry device to prevent cross-infection of the eyes

Abstract

This invention provides an intraocular pressure testing device to prevent cross-infection of the eyes. The device includes a base, a control lever, a display screen, an eye support mechanism, a testing instrument, and a placement frame. The testing instrument and the control lever are mounted on the base, and the display screen is located on the back of the testing instrument. This device utilizes the coordinated arrangement of the base, control lever, display screen, eye support mechanism, testing instrument, and placement frame. Compared to existing technologies that rely on opening the eyelid, this invention allows for changing the contact angle of the casing, enabling either the front or back of the casing to contact the patient's eyelid. When testing the other eye, the casing is flipped over, allowing the front side that has already contacted the patient's skin to turn outwards, while the back side, which has not yet contacted the skin, comes into contact with the patient. This significantly reduces the risk of cross-infection.

Description

Technical Field

[0001] This invention relates to the field of intraocular pressure testing equipment, specifically an intraocular pressure testing instrument to prevent cross-infection of the eyes. Background Technology

[0002] The non-contact tonometer used in this device blows compressed air onto the cornea of ​​the eye being tested, while simultaneously projecting measurement light onto the cornea from a light source. The device uses a photosensitive element to receive the reflected light from the cornea and detects the peak value of the output signal from the photosensitive element, thereby detecting a predetermined deformation of the cornea and thus determining the intraocular pressure value.

[0003] For example, a Chinese patent discloses an "intraocular tonometer" (patent number: CN201710663110.X), which includes a main unit and a detection unit. The main unit is the host part of the intraocular tonometer. The detection unit is movably mounted on the main unit. An auxiliary detection unit is set on the side of the detection unit facing the patient. The detection unit has an examination window. The auxiliary detection unit has an examination hole coaxial with the examination window. The auxiliary detection unit can rotate relative to the examination window. The auxiliary detection unit includes an auxiliary unit housing, an auxiliary opening module, and a rotation module. The auxiliary unit housing is connected to the auxiliary opening module. The auxiliary opening module rotates relative to the detection unit through the rotation module. The beneficial effects of this invention are that it can control the size of the patient's eyelid opening, prevent the patient from blinking, and improve the accuracy and efficiency of the intraocular pressure test. The rotation module ensures that the support part acts correctly on the bones around the eye socket, without being affected by the nasal bone. It can also automatically sense the applied pressure and perform sterilization.

[0004] However, when patients undergo intraocular pressure testing, some patients already have certain adverse symptoms or lesions in their eyes, which is why they come to the hospital for diagnosis. Although the aforementioned patent has the function of automatically opening the eyelids, the sheath that it contacts the patient's eyelids is not disposable. The sheath needs to contact both of the patient's eyes, which poses a risk of cross-infection. Summary of the Invention

[0032] This invention provides an intraocular pressure testing device to prevent cross-infection of the eyes, such as... Figure 1-8 As shown, the device includes a base 1, a joystick 2, a display screen 3, an eye support mechanism 6, a detector 4, and a mounting rack 5. The detector 4 and joystick 2 are mounted on the base 1, and the display screen 3 is located on the back of the detector 4. The mounting rack 5 and the eye support mechanism 6 are both located on the front of the detector 4. The device also includes a detection mechanism 10 and a main slide rail 9, which is horizontally positioned on the front of the detector 4. The detection mechanism 10 slides along the main slide rail 9, and the eye support mechanism 6 corresponds to the detection mechanism 10. The eye support mechanism 6, detection mechanism 10, joystick 2, and display screen 3 are all electrically connected to the detector 4.

[0033] It also includes a bottom pad 8 and a top pad 7, with the top pad 7 positioned at the top of the placement rack 5. The bottom pad 8 is positioned at the bottom of the placement rack 5. The top pad 7 and the bottom pad 8 correspond to the forehead and chin of the person, respectively.

[0034] The eye support mechanism 6 includes a movable contact component 27, a mounting component 25, a support 12, and a drive shaft 13. The support 12 is located on the front of the detector 4, and the drive shaft 13 is mounted on the support 12. The mounting component 25 is located on the movable end of the drive shaft 13, and the movable contact component 27 is pivotally connected within the mounting component 25.

[0035] Mounting assembly 25 includes a fixed frame 14, a telescopic frame 11, and two auxiliary rotating seats 28. The telescopic frame 11 is mounted on the movable end of the drive shaft 13, and the fixed frame 14 is mounted on the movable inner wall of the side of the telescopic frame 11. The two auxiliary rotating seats 28 are mounted on the bottom ends of the fixed frame 14. The movable contact assembly 27 is mounted on the output end of the auxiliary rotating seats 28.

[0036] The active contact assembly 27 includes two drive frame mechanisms 24 and a rotating block 22. The drive frame mechanisms 24 are located at the output end of the auxiliary rotating seat 28. The rotating block 22 is located at the output end of the drive frame mechanisms 24.

[0037] The movable contact assembly 27 also includes two electrically operated telescopic rods 15, two drive hinge seats 16, and an electrically operated telescopic rod 19. The electrically operated telescopic rods 15 are located inside the rotating block 22, and the drive hinge seats 16 are located on the movable ends of the electrically operated telescopic rods 15. The electrically operated telescopic rod 19 is located on the output ends of the drive hinge seats 16. 。

[0038] The active contact assembly 27 also includes two arc-shaped sensors 18, two snap-fit ​​seats 17, and a drive clamp 21. The arc-shaped sensors 18 are mounted on the movable end of the electric telescopic rod 19, and the snap-fit ​​seats 17 are fitted onto the fixed end surface of the electric telescopic rod 19. A V-shaped silicone pad 20 is fitted onto the arc-shaped sensors 18, with one end of the V-shaped silicone pad 20 detachably snapped into the snap-fit ​​seat 17. The two V-shaped silicone pads 20 correspond to the upper and lower eyelids of the human eye, respectively.

[0039] The V-shaped silicone pad 20 is tilted, and a slot is formed on the top of the V-shaped silicone pad 20. The arc-shaped sensor 18 is inserted into the V-shaped silicone pad 20 through the slot, and the snap-fit ​​seat 17 is detachably snapped into the slotted side of the V-shaped silicone pad 20. The front of the V-shaped silicone pad 20 contacts the eyelid of the person, while the back does not contact the eyelid of the person.

[0040] It also includes a rotating base 23 and a mounting plate 26. The rotating base 23 is located on the front of the detector 4. The mounting plate 26 is located on the output end of the rotating base 23.

[0041] The active contact component 27 also includes four snap-fit ​​blocks 29, which are symmetrically arranged in pairs on both sides of the V-shaped silicone pad 20.

[0042] It also includes two drive clamps 21, which are mounted on the mounting plate 26. The two drive clamps 21 correspond to two V-shaped silicone pads 20 respectively, and the two drive clamps 21 are detachably snapped into the snap-fit ​​blocks 29 on both sides of the V-shaped silicone pads 20 respectively.

[0043] Working principle: In use, the patient first places their chin on the bottom pad 8 and their forehead on the top pad 7. Then, the operator controls the lever 2 to align the detection mechanism 10 with the patient's left eye. Next, the operator controls the telescopic frame 11 to extend or retract, aligning the movable contact component 27 with the patient's eye. Then, the operator controls the drive hinge seat 16 to rotate the electric telescopic rod 19, bringing the front of the V-shaped silicone pad 20 into contact with the patient's upper and lower eyelids. Finally, the operator controls the electric telescopic rod 15 to retract, completing the opening of the patient's upper and lower eyelids for easier detection.

[0044] After the patient's left eye is examined, the patient is separated from the base pad 8. Then, the operator controls the drive shaft 13 to flip the movable contact component 27 to the other side. Simultaneously, the front of the V-shaped silicone pad 20, which was previously in contact with the patient's eyelid, is flipped to the back. This process is repeated for the right eye. This allows both sides of the V-shaped silicone pad 20 to be used simultaneously, greatly increasing the usable surface area and efficiency, while also effectively preventing cross-infection between the two eyes when using the same V-shaped silicone pad 20.

[0045] After the patient's examination is completed, the V-shaped silicone pad 20 is moved to the same side as the mounting plate 26. Then, the auxiliary rotating seat 28 is controlled to rotate the drive frame mechanism 24, positioning it laterally. Next, the rotating block 22 is controlled so that the locking seat 17 is positioned below the drive frame mechanism 24. Then, the rotating seat 23 flips the mounting plate 26, aligning the drive clamp 21 with the V-shaped silicone pad 20. The drive clamp 21 then picks up the locking block 29 on the V-shaped silicone pad 20, while the electric telescopic rod 19 extends, pushing the arc-shaped sensor 18 out of the locking seat 17. This completes the removal of the used V-shaped silicone pad 20 by the drive clamp 21. The entire process is performed without human intervention, effectively preventing hand contamination from contact with the V-shaped silicone pad 20.

[0046] In summary, this intraocular pressure testing device for preventing cross-infection of the eyes utilizes a base 1, a control lever 2, a display screen 3, an eye support mechanism 6, a testing instrument 4, and a placement frame 5 working together. Compared to the existing technology's eyelid-opening function, this invention can change the contact angle of the casing, allowing either the front or back of the casing to contact the patient's eyelid. Thus, when testing the other eye, the casing is flipped over, so that the front side that has already contacted the patient's skin is turned outwards, while the back side that has not contacted the skin comes into contact with the patient. This significantly reduces the risk of cross-infection.
