[0001] The utility model relates to the technical field of medical devices, and more specifically, to an endoscope brush. Background Art

[0002] In the medical field, endoscopes are an important diagnostic and treatment tool, widely used for the inspection and treatment of endoscopic lumens, such as the digestive tract and respiratory tract. However, over long-term use, various dirt, blood residues, and microorganisms easily accumulate inside the endoscope tubes. This not only affects the image quality of the endoscope but can also become a potential source of nosocomial infection.

[0003] Traditional endoscope cleaning methods often rely on manual operation, including using a brush to manually apply detergent into the endoscope channel for cleaning. This method has many shortcomings: First, the detergent must be prepared on-site, a tedious process that is prone to errors; second, manual application makes it difficult to ensure uniform coverage of the detergent on the inner wall of the endoscope channel, affecting cleaning effectiveness; third, the detergent's residence time and intensity in the channel are difficult to control, resulting in low cleaning efficiency.

[0004] Since an endoscope brush needs to be brushed back and forth at high frequency during use, an endoscope brush is provided which can automatically deliver enzyme liquid and firmly fix the enzyme liquid bullet, thereby improving the cleaning efficiency and safety of the endoscope.

[0009] As an improvement to the endoscope brush, the fixed tube is provided with a limiting strip, the end of the accommodating groove is provided with an opening, the limiting strip at least partially protrudes from the end surface of the fixed tube and can be inserted into the opening for cooperation.

[0010] As an improvement of the endoscope brush, the inner side of the limiting strip has a first flexible layer, which is used to contact and cooperate with the enzyme liquid bullet and to limit and fix it by filling the gap between the enzyme liquid bullet and the fixed tube.

[0011] As an improvement to the endoscope brush, a second flexible layer is provided at the bottom of the fixed cylinder, and after the upper cover is connected to the handle, the second flexible layer is squeezed and deformed.

[0012] As an improvement of the endoscope brush, at least a portion of the handle is transparent to form an observation portion, and the observation portion corresponds to the position of the receiving slot and is arranged along the length direction of the receiving slot.

[0013] As an improvement of the endoscope brush, the end of the handle has an external threaded portion, the upper cover has a connecting portion, and the inner side of the connecting portion is provided with an internal thread that matches the external threaded portion.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] An endoscope brush comprises: a handle 1 having a cavity 11; a brush rod 3 arranged at one end of the handle 1; and an infusion assembly arranged in the cavity 11; a recessed side of the handle 1 forms a receiving groove 12 for placing an enzyme liquid cartridge; the infusion assembly can be connected to the enzyme liquid cartridge in the receiving groove 12 to transport the enzyme liquid in the enzyme liquid cartridge to the brush rod 3 for outflow; the handle 1 is provided with a fixing assembly 4, which can be connected to the handle 1 to close the receiving groove 12 and limit the enzyme liquid cartridge in the receiving groove 12.

[0025] Specifically, a brush rod 3 is located on the handle 1 at the end opposite the fixing assembly 4 and is used for cleaning confined spaces such as endoscope tubes. The fixing assembly 4 is used to seal the receiving groove 12 and secure the enzyme cartridge, ensuring that the cartridge does not move or fall out during use. The infusion assembly uses a pump to extract the enzyme liquid from the cartridge and transfer it to the brush rod 3 for outflow.

[0026] When in use, the enzyme cartridge is first placed into the receiving groove 12. The retaining assembly 4 is connected to the handle 1 to seal the receiving groove 12 and secure the enzyme cartridge in place. The infusion assembly is connected to the enzyme cartridge, extracting the enzyme liquid from the cartridge. The enzyme liquid is then transported to the brush rod 3 via the infusion assembly and flows out from the brush rod 3 to clean the interior of the endoscope tube. The enzyme liquid flows through the infusion assembly to the brush rod 3, directly acting on the surface to be cleaned, quickly breaking down dirt and residue, and improving cleaning efficiency. This eliminates the need for manual on-site preparation of the enzyme liquid and manual application of the enzyme liquid to the endoscope tube or brush rod 3, further improving cleaning efficiency. The provision of the retaining assembly 4, while connected to the handle 1, seals the receiving groove 12 and secures the enzyme cartridge in place within the groove 12, ensuring that the enzyme cartridge does not fall off or move during use, thus preventing potential damage to the endoscope or the human body. This makes it easier to install and secure the enzyme cartridge, simplifying the operating process.

[0027] In some embodiments of the present application, the fixing assembly 4 includes an upper cover 41 having a groove 42 and a fixed cylinder 45 rotatably arranged in the groove 42. After the upper cover 41 is connected to the handle 1, the enzyme liquid bullet is inserted into the fixed cylinder 45, and the fixed cylinder 45 cooperates with the receiving groove 12 to completely cover the enzyme liquid bullet, thereby limiting and fixing the enzyme liquid bullet. Specifically, the groove 42 of the upper cover 41 is used to accommodate and install the fixed cylinder 45. When the upper cover 41 is connected to the handle 1, the enzyme liquid bullet is inserted into the fixed cylinder 45, and then the fixed cylinder 45 closely cooperates with the receiving groove 12 to completely cover the enzyme liquid bullet; this limits the movement of the enzyme liquid bullet and prevents the enzyme liquid bullet from falling off during operation.

[0028] In some embodiments of the present application, the end of the handle 1 has an external threaded portion 2, and the upper cover 41 has a connecting portion 43, and the inner side of the connecting portion 43 is provided with an internal thread that cooperates with the external threaded portion 2. Specifically, the external threaded portion 2 of the handle 1 and the internal thread of the connecting portion 43 of the upper cover 41 are screwed together, and by rotating the upper cover 41, a tight connection between the upper cover 41 and the handle 1 can be achieved. The threaded connection method enhances the overall structural stability of the endoscope brush and improves the service life of the product. Through tight threaded fit, the leakage of the enzyme liquid during the transportation process is effectively prevented, ensuring the cleaning effect and safety of the endoscope brush. When it is necessary to replace the enzyme liquid bullet or perform cleaning and maintenance, the handle 1 can be easily opened by rotating the upper cover 41, which is simple and quick to operate.

[0029] Since the fixed cylinder 45 and the upper cover 41 are rotatably connected, when the upper cover 41 is rotated to be threadedly connected to the handle 1, the fixed cylinder 45 will not rotate after the enzyme liquid cartridge is inserted into and contacts the fixed cylinder 45, thereby reducing the friction generated between the upper cover 41 and the enzyme liquid cartridge when being screwed, avoiding wear on the enzyme liquid cartridge.

[0030] In some embodiments of the present application, the fixed cylinder 45 is provided with a limiting strip 46, and an opening is provided at the end of the receiving groove 12. The limiting strip 46 partially protrudes from the end face of the fixed cylinder 45 and can be inserted into the opening to match. Specifically, since the limiting strip 46 partially protrudes from the lower end face of the fixed cylinder 45; before the upper cover 41 is connected to the handle 1, the limiting strip 46 of the fixed cylinder 45 must be aligned with the opening at the end of the receiving groove 12, and then the limiting strip 46 is inserted into the opening, and then the upper cover 41 is rotated to match the handle 1 thread. In this way, the fixed cylinder 45 is limited, and the fixed cylinder 45 is further prevented from rotating during the rotation connection of the upper cover 41, ensuring that the enzyme liquid bullet can be fixed without causing wear on the surface of the enzyme liquid bullet. The matching design of the limiting strip 46 and the opening significantly enhances the connection stability between the fixed cylinder 45 and the receiving groove 12, and reduces the risk of loosening due to vibration or impact factors.

[0031] In some embodiments of the present application, the inner side of the limiting strip 46 has a first flexible layer 47, which is used to contact and cooperate with the enzyme liquid bullet and is fixed by filling the gap between the enzyme liquid bullet and the fixed cylinder 45. Specifically, after the enzyme liquid bullet is inserted into the fixed cylinder 45, the first flexible layer 47 directly contacts the surface of the enzyme liquid bullet. Since the material of the first flexible layer 47 has certain elasticity and compressibility, it can closely fit the surface shape of the enzyme liquid bullet. The first flexible layer 47 fills the small gap between the enzyme liquid bullet and the inner wall of the fixed cylinder 45, thereby forming a close contact interface. As the fixed cylinder 45 and the accommodating groove 12 are closely matched, the first flexible layer 47 is squeezed, generating a certain rebound force, which is evenly distributed on the surface of the enzyme liquid bullet, further limiting the enzyme liquid bullet to prevent it from shaking during use, thereby enhancing the stability of the enzyme liquid bullet in the fixed cylinder 45. At the same time, the presence of the flexible layer can also alleviate the impact force generated by vibration or impact, further protecting the enzyme liquid bullet from damage.

[0032] The material of the first flexible layer 47 can be selected from (including but not limited to) silicone, rubber, foam plastic or sponge.

[0033] In other embodiments, multiple limiting bars 46 are provided, each of which is arranged in a circumferential and evenly spaced manner around the fixed barrel 45. Specifically, there are four limiting bars 46, one on each side of the fixed barrel 45. The four limiting bars 46, through the first flexible layer 47 of the four limiting bars 46, contact the enzyme cartridge, thereby providing a certain positioning and centering function, preventing the enzyme cartridge from being tilted and ensuring a good connection between the enzyme cartridge and the infusion assembly. The number of limiting bars 46 can be set as needed, including but not limited to 2, 3, 5, 6, 7, or 8.

[0034] In some embodiments of the present application, a second flexible layer is provided at the bottom of the fixing tube 45 , and after the upper cover 41 is connected to the handle 1 , the second flexible layer is squeezed and deformed.

[0035] Specifically, when the upper cover 41 is tightly connected to the handle 1, the second flexible layer in the fixed tube 45 contacts the enzyme liquid bullet and is subjected to pressure from the upper cover 41. Because the second flexible layer has a certain elasticity and plasticity, it deforms when squeezed, filling the space between the bottom of the fixed tube 45 and the enzyme liquid bullet, so that the enzyme liquid bullet fits tightly with the bottom of the receiving groove 12, improving the connection stability of the enzyme liquid bullet and the infusion assembly. The squeezing deformation of the second flexible layer also increases the stability of the enzyme liquid bullet in the fixed tube 45, reduces the shaking of the enzyme liquid bullet due to vibration or improper operation, and prevents the enzyme liquid bullet from falling off or shifting.

[0036] Since the second flexible layer has a certain degree of compressibility, it can adapt to enzyme liquid bullets of different heights. This allows the endoscope brush to adapt to enzyme liquid bullets of different heights, thereby improving the versatility and flexibility of the product.

[0037] The material of the second flexible layer can be selected from (including but not limited to) foam plastic, sponge, silicone or rubber.

[0038] In some embodiments of the present application, the handle 1 is partially transparent to form an observation portion, which corresponds to the position of the receiving tank 12 and is arranged along the length direction of the receiving tank 12. Specifically, the observation portion is arranged at a place corresponding to the position of the receiving tank 12 and extends along the length direction of the receiving tank 12. This ensures that the user can intuitively observe the usage status of the enzyme liquid bullet in the receiving tank 12. So that the user can replace the enzyme liquid bullet in time. Through the observation portion, the user can monitor the situation of the enzyme liquid bullet in the receiving tank 12 in real time, including whether the enzyme liquid bullet is in place, whether it is complete, whether there is leakage, etc.

[0039] In some embodiments of the present application, at least a portion of the top of the upper cover 41 protrudes to form a knob 44 to assist in rotating the upper cover 41. Specifically, the knob 44 protruding from the top of the upper cover 41 provides a clear operating area for the user to grasp and rotate. The provision of the knob 44 makes rotating the upper cover 41 more intuitive and easier to operate. The user only needs to grasp the knob 44 to easily rotate the upper cover 41.

[0040] In some embodiments of the present application, the bottom of the holding tank 12 has an interface 13 that is communicated with the enzyme liquid bullet, and the infusion component is connected to the interface 13, and the edge of the interface 13 is provided with a sealing rubber ring. The interface 13 at the bottom of the holding tank 12 is connected to the inside of the enzyme liquid bullet, forming a channel for liquid circulation. When the enzyme liquid bullet is placed in the holding tank 12 and fixed, the enzyme liquid can flow out through this interface 13. One end of the infusion component is tightly connected to the interface 13, ensuring that the path of the enzyme liquid flow is unobstructed. The sealing rubber ring provided at the edge of the interface 13 is tightly fitted at the connection between the infusion component and the interface 13, preventing the leakage of the enzyme liquid during transmission.
