Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-fog components, and more specifically, to an anti-fog protective cover. Background Technology
[0002] A digestive endoscope is a long, flexible tubular instrument with a camera and light source at the front end. It is inserted into the human body through the mouth or anus to perform medical examinations. The front end of digestive endoscopes on the market is generally transparent or covered with a transparent cover to provide waterproof protection and allow normal light transmission.
[0003] However, commercially available digestive endoscopes lack anti-fogging protection at their tips. Since the temperature of the endoscope is lower than body temperature during initial use, and the body contains fluids, this temperature difference can cause fogging at the tip. Fogging at the tip affects the camera's ability to capture images, impacting diagnostic results and causing inconvenience for medical staff. Therefore, we propose an anti-fogging protective cover. Utility Model Content
[0004] The purpose of this invention is to provide an anti-fog protective cover to address the deficiencies mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An anti-fog protective sleeve includes a digestive endoscope tube body. A fixed end is fixedly installed at the end of the digestive endoscope tube body. A protective sleeve is fixedly installed at the center of the top surface of the fixed end. A camera is fixedly installed at the center of the top of the protective sleeve. An electric heating ring is fixedly installed on the fixed end and is sleeved on the outside of the protective sleeve. A transparent protective tube is fixedly installed on the top surface of the fixed end and is sleeved on the outside of the protective sleeve and the electric heating ring. A transparent hemispherical cover is fixedly installed at the top of the transparent protective tube, and an outer transparent anti-fog layer is provided on the outer surface of the transparent hemispherical cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This utility model protects the camera internally by using a transparent protective cylinder and a transparent hemispherical cover. An electric heating ring is installed inside the transparent protective cylinder, which can heat the transparent protective cylinder and the transparent hemispherical cover, preventing fogging caused by a large temperature difference between the surface temperature of the transparent protective cylinder and the transparent hemispherical cover and the human body temperature.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figures 1-4 This utility model provides a technical solution: an anti-fog protective sleeve, including a digestive endoscope tube body 1, a fixed end 10 fixedly installed at the end of the digestive endoscope tube body 1, a protective sleeve 11 fixedly installed at the center of the top surface of the fixed end 10, a camera 12 fixedly installed at the center of the top of the protective sleeve 11, an electric heating ring 15 fixedly installed on the fixed end 10, the electric heating ring 15 is sleeved on the outside of the protective sleeve 11, the electric heating ring 15 is a constant temperature heating type electric heater, which can maintain constant temperature heating and avoid the heating temperature being too high or too low, affecting the use effect. Moreover, the constant temperature type electric heating ring 15 is a conventional technology, which will not be described in detail here.
[0026] Specifically, a transparent protective tube 16 is fixedly installed on the top surface of the fixed end 10. The transparent protective tube 16 is fitted over the outside of the protective sleeve 11 and the electric heating ring 15 for waterproof protection during operation. A transparent hemispherical cover 2 is fixedly installed on the top of the transparent protective tube 16. Both the transparent hemispherical cover 2 and the transparent protective tube 16 are made of transparent material and are used for normal image capture by the camera 12.
[0027] In this embodiment, an outer transparent anti-fog layer 20 is provided on the outer surface of the transparent hemispherical cover 2. The outer transparent anti-fog layer 20 can be made of nano-level hydrophilic material. The outer transparent anti-fog layer 20 contains hydrophilic active factors. These factors can change the tension of water droplets on the lens surface, so that the water droplets form a water film instead of small water droplets, thereby eliminating fog. The hydrophilicity allows water vapor to spread quickly on the surface, avoiding the formation of fog that obstructs vision, and achieving the effect of anti-fog protection.
[0028] In this embodiment, the camera 12 extends into the transparent hemispherical cover 2, which is a hollow hemispherical shape, so that the camera 12 can normally perform image capture operations at the part of the transparent hemispherical cover 2.
[0029] Specifically, an annular groove 13 is provided at the circumferential edge of the top surface of the fixed end 10, and a plug-in ring 161 is fixedly installed on the bottom surface of the transparent protective cylinder 16. The plug-in ring 161 is located in the annular groove 13 and is plugged into the annular groove 13. The size of the plug-in ring 161 is adapted to the size of the annular groove 13. The plug-in ring 161 is glued and fixed to the groove wall of the annular groove 13 with waterproof adhesive that is resistant to 60° to 80°, thus achieving the bonding and fixing operation. Moreover, the electric heating ring 15 can be disassembled and inspected after the waterproof adhesive is melted.
[0030] Furthermore, the outer diameter of the transparent protective tube 16 is equal to the outer diameter of the digestive endoscope tube body 1, making the outer surface smoother and preventing protrusions. An inner fitting ring 17 is fixedly installed on the inner wall of the transparent protective tube 16, which can fit and contact the top surface of the fixed end 10 to achieve positioning and assembly operations.
[0031] In addition, a support frame 151 is fixedly installed on one side of the bottom of the electric heating ring 15. The bottom of the support frame 151 is fixedly installed on the top surface of the fixed end 10 by fastening screws, which facilitates the fixed installation operation.
[0032] It is worth noting that the fixed end 10 is provided with a wire hole 14, which is connected to the interior of the digestive endoscope tube body 1 for normal wiring operations.
[0033] It is worth noting that the transparent protective cylinder 16 has multiple heat-conducting wires 18 arranged in a ring at equal intervals inside the cylinder. The heat-conducting wires 18 are arranged vertically, which makes it easier for heat to be transferred to the transparent protective cylinder 16.
[0034] When the anti-fog protective cover of this utility model is in use, after the electric heating ring 15 is connected to the external power supply and starts working, the electric heating ring 15 can perform constant temperature heating. After the heat is transferred to the transparent protective cylinder 16 and the transparent hemispherical cover 2, the transparent protective cylinder 16 and the transparent hemispherical cover 2 can also have a corresponding temperature, reducing the temperature difference between them and the human body, and further reducing the occurrence of fogging. In addition, the outer transparent anti-fog layer 20 can further eliminate fog and avoid obstructing vision.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
