Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an endoscope cleaning brush. Background Technology
[0002] As endoscopes are reusable medical devices requiring sterilization, the pre-sterilization cleaning process is crucial, with the cleaning brush playing a vital role. The endoscope's forceps channel must be cleaned using the cleaning brush. A well-designed endoscope cleaning brush can effectively improve the quality of endoscope cleaning, enhance sterilization, and effectively prevent endoscope-related infection problems.
[0003] Traditional cleaning brushes are typically made by twisting two strands of metal wire into a braid, with the bristles embedded in the metal brush handle. For example, Chinese utility model patent CN221284923U discloses a brush head and brush assembly for cleaning flexible endoscopes. The brush head includes a handle and a brush body connected to the handle. The brush body includes a brush handle and bristles disposed on the brush handle. The handle has a deformable elastic portion that adapts to the shape of the flexible tube when inserted into it, allowing it to pass freely through the tube. This invention enables the brush head to pass quickly and smoothly through the flexible tube, avoiding clogging or obstruction during use. It has the advantages of simple structure and ease of operation.
[0004] In the above solutions, firstly, the cost of using metal materials for the brush head is relatively high; secondly, the bristles are relatively thin and long, making them prone to breakage and shedding, causing secondary pollution; and thirdly, the bristles are prone to scratching the clamp channel when brushing back and forth inside the clamp channel. Summary of the Invention
[0005] To address the aforementioned problems, the purpose of this invention is to provide an endoscope cleaning brush that is inexpensive, easy to manufacture, and safe and efficient to use.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An endoscope cleaning brush includes an outer tube and a core rod, characterized in that: at least one sponge is sleeved on the core rod, the core rod is inserted through and fixed on at least one side of the outer tube, and the surface of the sponge extends beyond the outer wall of the outer tube; the outer tube is divided into at least two clamping tubes, and a sponge is clamped between two adjacent clamping tubes.
[0008] Preferably, the outer tube is provided with the core rod on both sides, and multiple sponge bodies are regularly sleeved on the core rod. The outer tube is configured as multiple clamping tubes, with two adjacent clamping tubes clamped on both sides of a sponge body.
[0009] Preferably, the sponge is elliptical or spherical.
[0010] Preferably, the end of the clamping tube is formed with a pressure ring that acts on the side wall of the sponge, or a pressure ring is clamped between the clamping tube and the sponge; the end face of the pressure ring facing the sponge is constructed as an arc surface adapted to the side wall of the sponge.
[0011] Preferably, the outer tube is a flexible tube.
[0012] Preferably, the core rod is a flexible plastic rod.
[0013] Preferably, the core rod is fixedly connected to the outer tube by extrusion or heat shrinking.
[0014] Preferably, the outer end of the core rod is provided with a stop block, and the inner end face of the stop block abuts against the adjacent clamping tube.
[0015] Preferably, the circumferential sidewall of the stop is set as an arc surface.
[0016] The present invention adopts the above technical solution and has the following beneficial effects:
[0017] ① The brush head is made of sponge, which has a more stable structure and is not easy to fall off. The material is soft and will not damage the endoscope canal. The sponge is easy to compress and deform after absorbing water or cleaning agent, so it can fit into the endoscope canal wall and clean the entire canal at once. The cleaning effect is good. If you want to achieve a better cleaning effect, you can install more sponges.
[0018] ② The outer tube is a flexible tube, and the core rod is a plastic part with a certain degree of elasticity. The cleaning brush can effectively clean the forceps channel even when the endoscope is bent.
[0019] ③ The corpus spongiosum is round or elliptical, which makes it easy to enter the endoscope channel and fits better against the endoscope channel wall after entering the endoscope channel.
[0020] ④ The endoscope cleaning brush is made entirely of non-metallic parts, which is easy to process, low in cost, and has a good cleaning effect.
[0021] The cleaning brush in this solution is used as follows:
[0022] Soak a sponge in water or detergent, hold the outer tube, and insert the sponge into the endoscope's forceps channel to squeeze out any dirt or debris, thus cleaning the channel. The first sponge will remove the dirt; multiple sponges can be used for repeated cleaning. The cleaning brush can be removed from the other end of the endoscope's forceps channel to prevent dirt from re-entering. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, unless otherwise specified, "plurality" means two or more, unless expressly limited otherwise.
[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0032] like Figures 1 to 4 An endoscope cleaning brush is shown, comprising an outer tube 1 and a core rod 2. At least one sponge 3 is sleeved on the core rod 2. The core rod 2 is inserted through and fixed on at least one side of the outer tube 1. The surface of the sponge 3 extends beyond the outer wall of the outer tube 1. The outer tube 1 is divided into at least two clamping tubes 4, and a sponge 3 is clamped between two adjacent clamping tubes 4.
[0033] In the above technical solution, the brush head is made of sponge, which is sleeved and positioned on the core rod. The core rod passes through and fixes at least one side of the outer tube. The outer tube is configured into multiple clamping tubes, so that the sponge can be better clamped and fixed from both sides. The surface of the sponge extends beyond the outer wall of the outer tube to ensure that the sponge can act on the inner wall of the endoscope forceps channel.
[0034] The structure of the sponge is relatively more stable and less likely to fall off. Its soft material will not damage the endoscope canal. The sponge can easily compress and deform after absorbing water or cleaning agent, so it can fit into the endoscope canal wall and clean the entire canal in one go, resulting in a good cleaning effect.
[0035] Furthermore, the core rods 2 are inserted through both sides of the outer tube 1, and multiple sponge bodies 3 are regularly sleeved on the core rods 2. The outer tube 1 is configured as multiple clamping tubes 4, with two adjacent clamping tubes 4 clamping each other on both sides of a sponge body 3. In this technical solution, core rods are set on both sides of the outer tube, and multiple sponge bodies are set on the core rods. After the cleaning brush enters the clamping channel from one side, each sponge body will clean the clamping channel once. The multiple sponge bodies on both sides can achieve better cleaning effect and improve cleaning efficiency.
[0036] Furthermore, the sponge 3 is elliptical or spherical. In this technical solution, the sponge is elliptical or spherical, which makes it easier to enter the endoscope channel and allows it to fit more closely to the endoscope channel wall after entering the endoscope channel.
[0037] Furthermore, the end of the clamping tube 4 is formed with a pressure ring 5 that acts on the side wall of the sponge body 3, or a pressure ring 5 is clamped between the clamping tube 4 and the sponge body 3; the end face of the pressure ring 5 facing the sponge body 3 is constructed as an arc surface adapted to the side wall of the sponge body 3. In this technical solution, the pressure ring at the contact end between the clamping tube and the sponge body can increase the contact area with the sponge body and better fix the sponge body.
[0038] Furthermore, the outer tube 1 is a flexible tube, and the core rod 2 is a flexible plastic rod. In this technical solution, the outer tube is a flexible tube, and the core rod is a flexible plastic component, allowing the cleaning brush to effectively clean the endoscope channel even when the endoscope is bent.
[0039] Furthermore, the core rod 2 is fixedly connected to the outer tube 1 by extrusion or heat shrinking. In this technical solution, the inner end of the core rod 2 is fixedly connected to the outer tube 1 by extrusion or heat shrinking, which makes the connection between the core rod and the outer tube more stable.
[0040] Furthermore, a stop 6 is provided at the outer end of the core rod 2, and the inner end face of the stop 6 abuts against the adjacent clamping tube 4. In this technical solution, the stop is provided at the outer end of the core rod. The stop is formed by hot-melt extrusion or pressed onto the outer end of the core rod, which can effectively prevent the outer tube from detaching and improve structural stability.
[0041] Furthermore, the circumferential sidewall of the stop block 6 is configured as an arc surface. In this technical solution, configuring the circumferential sidewall of the stop block 6 as an arc surface can reduce friction and prevent scratching of the inner wall of the clamp channel when the stop block enters the clamp channel and touches its inner wall.
[0042] In addition, the endoscope cleaning brush is made entirely of non-metallic parts, which makes it easy to process, low in cost, and provides good cleaning results.
[0043] In this specific embodiment, the existing endoscope cleaning brush uses a structure in which bristles are embedded in a metal brush rod. This structure has problems such as relatively high cost of metal materials, relatively thin and long bristles that are easy to break and fall off, causing secondary pollution, and the bristles easily scratching the clamp channel when brushing back and forth in the clamp channel. The above solution uses a sponge as the brush head, and the sponge is sleeved and positioned on the core rod. The core rod passes through and fixes at least one side of the outer tube. The outer tube is configured into a multi-segment clamp tube, which can better clamp and fix the sponge from both sides. Furthermore, the surface of the sponge extends beyond the outer wall of the outer tube to ensure that the sponge can act on the inner wall of the endoscope clamp channel.
[0044] The structure of the sponge is relatively more stable and less likely to fall off. Its soft material will not damage the endoscope canal. The sponge can easily compress and deform after absorbing water or cleaning agent, so it can fit into the endoscope canal wall and clean the entire canal in one go, resulting in a good cleaning effect.
[0045] The cleaning brush in this solution is used as follows:
[0046] Soak a sponge in water or detergent, hold the outer tube, and insert the sponge into the endoscope's forceps channel to squeeze out any dirt or debris, thus cleaning the channel. The first sponge will remove the dirt; multiple sponges can be used for repeated cleaning. The cleaning brush can be removed from the other end of the endoscope's forceps channel to prevent dirt from re-entering.
[0047] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
