Description

Technical Field

[0001] This utility model relates to the field of slit lamp technology, specifically to a slit lamp bracket designed to prevent cross-infection. Background Technology

[0002] As a key piece of equipment in ophthalmology, the slit lamp is widely used in the diagnosis and treatment of eye diseases. Through its high-intensity focused beam and microscope system, it can clearly observe the structures of the eye, helping doctors to accurately diagnose lesions in the cornea, lens, retina, and other parts of the eye.

[0003] Currently, slit lamp holder designs include a chin rest and a forehead support, components that come into direct contact with the patient's skin during use. Because each patient's skin condition and hygiene habits differ, pathogens such as bacteria, viruses, or fungi may remain after contact with the skin. Failure to thoroughly disinfect the holder after each patient's use could lead to the spread of pathogens, increasing the risk of cross-infection. To mitigate this risk, healthcare facilities typically clean the holder with alcohol or other disinfectants after each use. However, this disinfection method can easily leave disinfectant residues, which some patients may be sensitive to, potentially causing skin irritation, redness, or allergic reactions upon contact. Furthermore, frequent use of disinfectants can corrode or damage the holder's materials, shortening the device's lifespan. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cross-infection-proof slit lamp bracket, which solves the problems mentioned in the background art.

The outer side wall of the top of the outer support 3 is fixed with a forehead pad 31. The end of the paper separator roll 81 extends to the forehead pad 31. The inner side wall of the outer support 3 is rotatably connected with a constraint assembly 7, which is used to flip and position the tissue box assembly 6.

[0028] 1. By using disposable isolation paper at the contact point between the patient's chin and the curved support plate, each examiner only needs to tear off one piece of isolation paper after completing the examination. The operation is simple, and stacking and reserving multiple isolation paper pieces can maximize the needs of the examination on the same day.

[0029] 2. The isolation paper roll can extend outward to the front of the forehead pad to form a protective structure and avoid cross-infection. After the examination, tear off the extended isolation paper and continue to pull it outward for a certain length to cover the forehead pad.

[0030] In this embodiment, the interior of the isolation paper sheet 9 is provided with perforations 91, and the surface of the arc-shaped support plate 4 is symmetrically provided with positioning holes 42. The positioning screw 5 passes through each perforation 91 and positioning hole 42 from top to bottom, and a locking nut 51 is screwed onto the bottom of the positioning screw 5.

[0031] In the above scheme, the operator pre-drills holes, then passes the positioning screw through multiple isolation paper pieces in sequence, places the isolation paper pieces on the arc-shaped support plate, extends the positioning screw out of the positioning hole, and finally screws on the locking nut.

[0032] In this embodiment, the paper dispenser assembly 6 includes a first cylindrical cover 61 and a second cylindrical cover 62. Both the first cylindrical cover 61 and the second cylindrical cover 62 are semi-cylindrical structures. The first cylindrical cover 61 and the second cylindrical cover 62 are joined together to form a cylindrical structure. A paper tube 8 is rotatably placed inside the cylindrical structure.

A fixing column 72 is connected between the side walls of the two flipping frames 73. A pressure roller 75 is sleeved on the outer wall of the fixing column 72. One side of the pressure roller 75 is attached to the outer wall of the first cylindrical cover 61.

[0036] In the above scheme: the guide plate can guide the end of the isolation paper roll to the forehead pad;

[0037] The coupling shaft and the support plate are connected by a damped rotation. The pressure roller is attached to the first cylinder cover, which can help press down the first cylinder cover and ensure its stability. When it is necessary to remove the first cylinder cover to replace the isolation paper roll, the guide plate is lifted and flipped to make the pressure roller disengage from the first cylinder cover, and then the first cylinder cover can be pulled out inward.
