Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a disposable nasal endoscope sleeve with a light source. Background Technology

[0002] Traditional nasal endoscopes are typically reusable and have the following drawbacks: First, infection risk: incomplete disinfection of the endoscope can easily lead to cross-infection between patients, especially for immunocompromised patients; Second, reliance on external light source: a cold light source host needs to be connected via fiber optic cable, which is cumbersome and restricts mobility; Third, high cost: the maintenance and disinfection costs of reusable endoscopes are high, making them difficult to popularize in primary healthcare institutions.

[0003] While disposable endoscopes (such as bronchoscopes) exist in the existing technology, they are complex in structure and too expensive. Furthermore, nasal endoscopes require smaller size and specific illumination angles, making them difficult to directly adapt.

[0004] To address these issues, we provide a low-cost, integrated, independent light source, disposable nasal endoscope sleeve to solve the problems mentioned in the background art, such as incomplete disinfection of the endoscope leading to cross-infection among patients, especially for immunocompromised patients; the need for the nasal endoscope to be connected to the cold light source host via optical fiber, resulting in cumbersome operating cables and restrictions on mobility; and the high maintenance and disinfection costs of reusable endoscopes.

Figures 1-4 The disposable nasal endoscope sleeve with light source in this embodiment has a main body including a sleeve body 100, a central cylinder 200 and an LED array 300.

[0032] The cannula 100 is assembled with the central cylinder 200 through a hollow channel. The cannula 100 itself is soft and does not easily irritate the nasal cavity. A hollow channel is provided in the middle of the cannula. In this embodiment, the front end of the cannula 100 is transparent and has a round head.

[0033] The central cylinder 200 can keep the cannula 100 upright, making it easy to insert into the nasal cavity. It is sealed by the sealing ring 210 to prevent body fluid from flowing back and contaminating the nasal endoscope. Specifically, the central cylinder 200 is set inside the hollow channel. In this embodiment, the central cylinder 200 is provided with a sealing ring 210 on its outer periphery. The sealing ring 210 is press-fitted with the inner wall of the hollow channel.

[0034] The LED array 300 is powered by a micro battery power supply 340. The LED array 300 is ring-shaped, freeing the operator from dependence on an external cold light source. It eliminates the need for cumbersome cables and optimizes the mobility limitations of the cold light source host. Through a brightness control module, the brightness of the LED array 300 can be adjusted according to different needs, thereby helping personnel to better perform nasal endoscopy examinations. Specifically, the LED array 300 is disposed inside the front end interlayer of the cannula body 100. In this embodiment, a brightness adjustment module 310 is disposed inside the interlayer of the cannula body 100. The degree adjustment module 310 includes an RC delay module and a flexible circuit board. The side wall of the sleeve body 100 is provided with a sensing area 330. A magnetic reed switch 320 is provided inside the sensing area 330. The magnetic reed switch 320 is electrically connected to the RC delay module.

[0035] The opening retainer 400 keeps the transparent cover stable by pressing the extension sleeve 411. The extension sleeve can extend the protection and prevent the cannula body 100 from being contaminated. After examining a patient, the opening retainer 400 can be opened and the transparent cover 410 can be discarded for one-time disposal. Specifically, the opening retainer 400 presses the transparent cover 410 that is fitted on the front end of the cannula body 100. The front end of the cannula body 100 is transparent. The rear end of the transparent cover 410 is provided with the extension sleeve 411. The opening retainer 400 presses the extension sleeve 411 on the outer periphery of the cannula body 100. The two ends of the opening retainer 400 are respectively provided with clamps 401.

[0036] Combination Figures 1-4 The disposable nasal endoscope sleeve with light source in this embodiment is used as follows: First, tear open the sterile packaging and insert the nasal endoscope into the sleeve body 100 until it is fully inserted. The person presses the sensing area 330, the magnetic reed switch 320 closes, and the LED light array lights up. The person can control the brightness of the LED light array by changing the pressing time using the brightness adjustment module 310. After the nasal endoscopy is completed, the person presses the sensing area 330 again to turn off the LED light array, pulls out the nasal endoscope, and the opening retainer 400 keeps the transparent cover stable by pressing the extension sleeve 411. The extension sleeve can extend the protection and prevent the sleeve body 100 from being contaminated. After examining a patient, the opening retainer 400 can be opened and the transparent cover 410 can be discarded for single disposal.
