Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device cleaning equipment technology, specifically a brush device for cleaning tubular instruments. Background Technology
[0002] Lumen instruments, as a special type of instrument with a slender, hollow internal structure, are widely used in medical, industrial, and other fields. Cleaning them is a crucial pretreatment step to ensure the effectiveness of subsequent disinfection and sterilization, prevent cross-contamination, and maintain instrument performance. However, the complex internal structure of some instruments, often with steps, joints, and other geometric shapes formed by changes in inner diameter, presents a significant challenge to thorough cleaning.
[0003] Currently, cleaning the interior of pipe cavities often employs through-type long-handled brushes. While these brushes can enter the pipe cavity, their bristle diameter is typically fixed, and the brush head shape is not adjustable. When the brush head passes through joints with different inner diameters, it is difficult to fully conform to the inner wall of the diameter-changing area, especially in the grooves and shoulder angles formed by the connection between larger and smaller inner diameter pipe sections, thus creating cleaning "blind spots." Therefore, this invention proposes a pipe cavity instrument cleaning brush device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a cleaning brush device for tubular instruments to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning brush device for tubular instruments, comprising a handheld part and an operating part. An arc-shaped elastic sheet is connected to the handheld part and is connected to the operating part. A fixed tube is fixed to the operating part, and a scale plate is provided on the fixed tube. A fixed column is connected to the fixed tube, and a telescopic three-dimensional mechanism is provided on the fixed column. Multiple brushes are provided on the telescopic three-dimensional mechanism. The operating part can move relative to the handheld part and compress the arc-shaped elastic sheet, thereby driving the telescopic three-dimensional mechanism to move through the fixed tube, so that the multiple brushes switch between a retracted state and an extended state.
[0006] Preferably, the telescopic three-dimensional mechanism includes a plurality of second connecting rods hinged to a fixed column, with a mounting plate hinged to the end of the plurality of second connecting rods away from the fixed column, a first connecting rod hinged to the mounting plate, and a top fixing plate hinged to the end of the first connecting rod away from the mounting plate.
[0007] Preferably, a middle long rod is fixedly connected to the lower end of the top fixing plate, and the middle long rod slides through the fixing column, the fixing tube and the operating part and is fixedly connected to the hand-held part.
[0008] Preferably, the brush is mounted on the mounting plate and moves together or apart as the mounting plate moves.
[0009] Preferably, there are multiple first connecting rods and multiple second connecting rods. The multiple first connecting rods are arranged in a circular array with the axis of the middle long rod as the center, and the multiple second connecting rods are simultaneously arranged in a circular array with the axis of the middle long rod as the center.
[0010] Preferably, the number of mounting plates is consistent with the number of second connecting rods and they are arranged in a circular array synchronously.
[0011] Preferably, the scale plate is arranged along the axial direction of the fixed tube and fixed to the outer wall surface of the fixed tube.
[0012] Compared with the prior art, the beneficial effects of this utility model are: By incorporating a handheld part, an operating part, and a telescopic three-dimensional mechanism, and utilizing the elastic deformation of an arc-shaped elastic sheet, the operator can easily control the retraction and expansion of the brush head by pressing and releasing the operating part. The axial movement of the fixed column can be converted into the radial convergence and dispersion movement of multiple mounting plates and their brushes, thereby allowing the brush head to compactly enter the tube cavity and expand at the connection points that need cleaning, so that the brushes can fully conform to the tube walls of different inner diameters and effectively clean the blind spots in grooves and connections.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between 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.
[0022] Please see Figures 1 to 6 This utility model provides a technical solution: a cleaning brush device for tubular instruments, including a handheld part 1 and an operating part 2, which are elastically connected by an arc-shaped elastic sheet 3. The arc-shaped elastic sheet 3 is a conventional arc-shaped elastic connector, and its two ends are respectively fixed to the upper end of the handheld part 1 and the lower end of the operating part 2 by bolts. The connection nodes fit tightly and firmly, and can stably withstand the elastic deformation during pressing and the restoring force during reset. The end of the operating part 2 away from the handheld part 1 is fixedly connected to a fixed tube 4. The fixed tube 4 is a hollow structure, and its axis is coincident with the central axis of the operating part 2. The outer wall of the fixed tube 4 is fixed with a scale plate 5 along the axial direction. The scale markings on the scale plate 5 increase along the direction of insertion into the tubular cavity, which can intuitively reflect the depth of the device into the tubular cavity and provide support for accurate positioning of the cleaning position.
[0023] like Figure 2 and Figure 3 As shown, the end of the fixed tube 4 away from the operating part 2 is fixedly connected to the fixed column 6. The fixed column 6 is also a hollow structure. In the telescopic three-dimensional mechanism 7, the lower end of the top fixed plate 72 is fixedly connected to the middle long rod 71. The middle long rod 71 slides through the hollow channel of the fixed column 6, the hollow channel of the fixed tube 4 and the reserved through hole of the operating part 2 in sequence, and is finally welded and fixed to the handheld part 1 to ensure that the top fixed plate 72 remains relatively stable during the operation of the device.
[0024] like Figure 4 , Figure 5 as well as Figure 6As shown, one end of each of the multiple first connecting rods 73 is hinged to the lower surface of the top fixing plate 72, and the multiple first connecting rods 73 are evenly distributed in a circular array with the axis of the middle long rod 71 as the center to ensure balanced force. Each first connecting rod 73 is hinged to a mounting plate 74 at the end away from the top fixing plate 72. The brush 8 is fixed to the side of the mounting plate 74 away from the first connecting rod 73 by bolts or adhesive to ensure the connection is firm during the brushing process.
[0025] Meanwhile, a second connecting rod 75 is also hinged to each mounting plate 74. The end of the second connecting rod 75 away from the mounting plate 74 is hinged to the upper end face of the fixed column 6. The multiple second connecting rods 75 are also arranged in a ring array with the axis of the middle long rod 71 as the center. Their number is consistent with the number of the first connecting rod 73 and the mounting plate 74, forming a symmetrical linkage transmission structure.
[0026] In practical applications, this device can be adapted to the cleaning needs of instruments with different inner diameters and variable diameter structures. When the brush head needs to be inserted into the lumen, the operator holds the handle 1 and presses the operating part 2 towards the handle 1. At this time, the arc-shaped elastic sheet 3 is squeezed and elastically contracts. The operating part 2 drives the fixed tube 4 and the fixed column 6 to move towards the handle 1 along the axis of the middle rod 71.
[0027] During the movement of the fixed column 6, a pulling force is applied to the mounting plate 74 through the second connecting rod 75. Since one end of the first connecting rod 73 is hinged to the fixed top mounting plate 72, under the combined action of the limiting force of the first connecting rod 73 and the pulling force of the second connecting rod 75, multiple mounting plates 74 converge towards the axis of the middle long rod 71, thereby causing the brush 8 to shrink into a compact shape and smoothly pass through the narrow inlet and slender pipe section of the cavity.
[0028] When the brush head reaches the critical cleaning areas such as the reducing joint, groove, or shoulder angle inside the tube, the operating part 2 is released, and the compressed arc-shaped elastic sheet 3 releases its elastic restoring force, pushing the operating part 2 to reset away from the handheld part 1. The fixed tube 4 and the fixed post 6 reset synchronously with the operating part 2.
[0029] When the fixed column 6 is reset, the second connecting rod 75 applies a pushing force to the mounting plate 74. With the support of the first connecting rod 73, multiple mounting plates 74 simultaneously spread out in a direction away from the middle long rod 71, so that the brush 8 can be fully unfolded and closely fit the inner walls of the pipes and grooves of different inner diameters.
[0030] At this time, the operator can rotate or reciprocate by holding the handle 1 and the operating part 2, and the brush 8 can thoroughly clean the "blind spots".
[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
