Description

A tear film detection kit for keratitis Technical Field

[0001] This invention belongs to the field of medical device technology, specifically referring to a tear film detection kit for keratitis. Background Technology

[0002] Fungal keratitis is an infectious corneal disease caused by pathogenic fungi with a very high rate of blindness. It has a slow onset and a long course, lasting 2 to 3 months, often presenting with corneal ulcers within days of onset. To date, more than 70 species of fungi have been identified as causing corneal infections. Based on their different pathogenic roles in ocular infections, fungi are divided into two main categories: filamentous fungi and yeasts. For targeted treatment of keratitis, tear sampling and testing of keratitis patients are necessary.

[0003] Patent CN221485445U discloses a tear test strip and test kit for the diagnosis of fungal keratitis. The test strip includes a carrier film with a test line and a control line. An antibody pad is adhered to the top of the carrier film near the test line, and a sample pad is adhered to the top side of the antibody pad. The free end of the sample pad contacts the eye. Due to fungal infection or other reasons, patients' eyes are often habitually closed, making it difficult for the free end of the sample pad to contact the patient's eye. Therefore, it is difficult for the tear sample to penetrate the sample pad. Furthermore, the curved shape of the eye makes it difficult to conform to the patient's eye shape, resulting in significant sampling challenges.

[0004] Therefore, a tear film detection kit for keratitis is proposed to solve the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a keratitis tear test kit. By pressing down on the head, the patient's upper and lower eyelids can be kept open, and the test strip can be adapted to the shape of the patient's eyeball, so as to better complete the tear collection and testing.

[0006] The technical solution adopted by this invention is as follows: This invention proposes a tear film detection box for keratitis, including a shell, the shell being a cylindrical structure with an open lower end, the outer wall of the shell being symmetrically provided with through grooves, a central shaft being slidably provided through the upper center of the shell, a pressing and pushing component being provided between the central shaft and the lower wall of the shell, a pressing component being provided between the upper end of the central shaft and the upper wall of the shell, an eyelid opening component being provided at the through groove of the shell, and an eye anastomosis mechanism being provided between the lower end of the central shaft and the lower part of the inner wall of the shell, the eye anastomosis mechanism including an anastomosis linkage component, an eye anastomosis head and a test strip, the eye anastomosis head being located at the lower end of the central shaft, the anastomosis linkage component being located between the eye anastomosis head and the inner wall of the shell, and the test strip being installed on the eye anastomosis head.

[0007] Furthermore, the downward pushing assembly includes a mounting frame, a transmission rack, a transmission gear, a rotating frame, a rotating shaft, and a push plate. The mounting frame is symmetrically arranged on the inner upper wall of the housing. The rotating shaft is rotatably located at the lower end of the mounting frame. The transmission gear is located on the rotating shaft. The rotating frame is located on the rotating shaft and is situated on both sides of the transmission gear. The push plate is located on the rotating frame.

[0008] Furthermore, the eyelid opening assembly includes a fixed frame, a guide rod, a spring baffle, a spring, a movable groove, a connecting column, and a friction foot. The fixed frame spans across both sides of the through groove, the guide rod slides through the fixed frame, the spring baffle is located at the outer end of the guide rod, the movable groove is located at the inner end of the guide rod, the movable groove is a U-shaped groove, the connecting column is located on the lower end face of the movable groove, and the friction foot is located at the lower end of the connecting column.

[0009] Furthermore, the ocular anastomosis head includes a fixed plate, a movable plate, a connecting plate, a torsion spring, and a connecting shaft. The fixed plate is located at the lower end of the central shaft, the connecting plates are symmetrically located at the ends of the fixed plate, the connecting shaft is located between the connecting plates, the movable plate is located on the connecting shaft, the torsion spring is sleeved on the connecting shaft, and the two ends of the torsion spring are respectively located on the movable plate and the connecting plate.

[0010] Furthermore, the matching linkage assembly includes a horizontal plate, a wedge plate, and a linkage plate. The two ends of the horizontal plate are located on the inner sidewall of the housing, and a linkage groove is provided in the middle of the horizontal plate. The wedge plate is symmetrically arranged on the inner sidewall of the linkage groove and located on both sides of the central axis. One end of the linkage plate is fixedly mounted on the movable plate, and the other end of the linkage plate slides along the wedge plate.

[0011] Furthermore, the outer end of the push plate is slidably disposed within the movable groove.

[0012] Furthermore, the pressing assembly includes a pressing head and a second spring. The pressing head is located at the upper end of the central shaft, and the second spring is sleeved on the central shaft. The two ends of the second spring are respectively located on the upper wall of the pressing head and the housing.

[0013] Furthermore, the fixed plate and the movable plate are symmetrically provided with slots at their edges, the slots being L-shaped, and the edge of the test paper is placed inside the slot.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows:

[0015] 1. Press down the pressure head, which presses down the central shaft and transmission rack, thereby driving the rotating shaft and rotating frame to rotate. The rotating frame drives the push plate to swing upward, and the push plate pushes the moving trough outward. The moving trough pushes the guide rod outward. At the same time, the moving trough drives the connecting column and friction feet to move outward. The two friction feet open the patient's eyelids outward, so that the patient's eyeballs are exposed, avoiding the patient's habitual closing of the eyes, which would affect the collection and testing of tear fluid.

[0016] 2. When the central axis is pressed down, the central axis simultaneously drives the fixed plate, the movable plate, and the linkage plate to move downward. The linkage plate moves along the wedge plate, and the wedge plate pushes the linkage plate outward. The linkage plate drives the outer end of the movable plate to rotate downward, so that the fixed plate and the movable plate form a concave shape. The concave shape fits the patient's eye. At the same time, the movable plate and the fixed plate drive the test strip to stick to the eyeball, and the patient's tears are absorbed by the test strip. Attached Figure Description
