Description

Technical Field

[0001] A retractable tubular cleaning and testing device belongs to the field of medical device cleaning technology. Background Technology

[0002] With the development of medical technology, complex and precise medical devices and tubular medical devices (such as endoscopic instruments, various catheters, surgical suction heads, puncture needle lumens, etc.) are increasingly widely used in clinical practice. The internal structure of these devices is complex, long and narrow, and difficult to observe directly, which makes them difficult and risky to clean. Residual blood, tissue, microorganisms or chemicals may cause infection. Therefore, ensuring thorough cleaning is a key link in medical safety.

[0003] Existing lumen cleaning testing devices typically employ fixed-length rigid (e.g., glass, plastic) or soft (e.g., silicone) lumen structures. These devices suffer from significant problems and limitations in use, such as: fixed length leading to poor adaptability; fixed-length testing devices cannot effectively simulate and verify the actual cleaning capabilities of cleaning machines for instruments of different lengths; and insufficient representativeness of monitoring results. Due to the inability to flexibly match the actual length of the instrument under test, monitoring results obtained using a single fixed-length device may not comprehensively and accurately reflect the actual cleaning capabilities of the cleaning machine for various sizes of lumen instruments, posing a risk of monitoring blind spots or unrepresentative data, and failing to meet diverse verification needs. Utility Model Content

[0020] Figures 1-3 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-3 The present invention will be further described below.

[0021] Reference Figures 1-3 The retractable tubular cleaning and testing device includes a first connecting pipe 1, a second connecting pipe 2, a fixed testing box 3, a sliding testing box 4, and a testing plate 5. The fixed testing box 3 and the sliding testing box 4 are connected by a sliding device. The first connecting pipe 1 is disposed inside the sliding testing box 4, and the second connecting pipe 2 is disposed inside the fixed testing box 3. The first connecting pipe 1 and the second connecting pipe 2 are slidably connected. One end of the second connecting pipe 2 communicates with the testing cavity 301, and the other end can be connected to the cleaning equipment or placed directly in the cleaning machine. The testing cavity 301 is disposed inside the fixed testing box 3, and the testing plate 5 is disposed inside the testing cavity 301. In other embodiments, the end of the first connecting pipe 1 may be connected to both the testing cavity 301 and the cleaning equipment.

[0022] Specifically, the fixed detection box 3 and the sliding detection box 4 are frame-type open boxes, with three sides forming a frame that opens on one side. The open ends of the fixed detection box 3 and the sliding detection box 4 are arranged opposite each other and connected by a sliding device. The sliding device of this utility model includes a slider 7 and a slide rail 8. The slider 7 is provided on the inner walls of both sides of the open end of the fixed detection box 3, and the slide rail 8 is provided at the same position on the outer walls of both sides of the open end of the sliding detection box 4. The slider 7 slides on the slide rail 8. The sliding device of this utility model has three sets arranged in the vertical direction, which drive the sliding detection box 4 to slide relative to the fixed detection box 3.

[0023] The fixed detection box 3 has a solid interior on the side away from the opening. The interior of this solid is hollow, forming a detection cavity 301. The detection cavity 301 is rectangular, and a rectangular detection piece 5 is placed inside it. The detection piece 5 has brightly colored simulated contaminants. A threaded opening is located on one side wall of the detection cavity 301. The diameter of the opening is larger than the width of the detection piece 5, allowing the detection piece 5 to be placed inside the detection cavity 301. A plug 10 is located at the opening and is threadedly connected to it.

[0024] The first connecting pipe 1 of this utility model is a rigid pipe made of plastic or the like, and the second connecting pipe 2 is a flexible pipe made of rubber or the like. The outer diameter of the first connecting pipe 1 is equal to the inner diameter of the second connecting pipe 2. The shape of the second connecting pipe 2 includes straight, U-shaped, and L-shaped. The first connecting pipe 1 is U-shaped. The second connecting pipe 2 connected to the detection cavity 301 is straight, and the second connecting pipe 2 connected to the cleaning device is L-shaped. The straight and L-shaped pipes are alternately connected by two U-shaped second connecting pipes 2 and three U-shaped first connecting pipes 1 to form a simulated detection cavity that is curved. The two U-shaped second connecting pipes 2 are connected to the fixed detection box 3 through fixed handrail rings 302, and the three U-shaped first connecting pipes 1 are connected to the handrail 9 through three handrail rings 901.

[0025] The simulated cavity of this utility model has two layers, upper and lower. The detection cavity 301 has two connecting ports. The second connecting pipe 2 of the upper layer is connected to the first connecting port 11, and the second connecting port 12 of the lower layer is connected to the first connecting port 11. The first connecting port 11 and the second connecting port 12 are respectively located on the same side of the detection cavity 301 at the upper and lower positions. The end of the L-shaped second connecting pipe 2 of the upper layer is the third connecting port 13, which passes through the front of the fixed detection box 3 and is connected to the cleaning device. The fourth connecting port 14 of the lower layer is arranged opposite to that of the upper layer.

[0026] A support plate 6 is provided between the two side walls of the sliding detection box 4 to support the second connecting pipe 2. The support plate 6 has through holes, the diameter of which is less than or equal to the outer diameter of the second connecting pipe 2, thus providing support for the second connecting pipe 2. In other embodiments, the second connecting pipe 2 can also be made of rigid plastic pipe, in which case a sealing ring is installed at the connection end with the first connecting pipe 1.

[0027] The outer wall of the first connecting pipe 1 is provided with protrusions 101 spaced apart, and the inner wall of the second connecting pipe 2 is provided with grooves 201 spaced apart. The second connecting pipe 2 is sleeved on the first connecting pipe 1, and the protrusions 101 of the overlapping part are engaged in the grooves 201, thus locking the first connecting pipe 1 and the second connecting pipe 2 together. Pulling the first connecting pipe 1 causes it to slide inside the second connecting pipe 2 until the next protrusion 101 engages with the groove 201, thereby changing the length of the overlapping part between the first connecting pipe 1 and the second connecting pipe 2.

[0028] It also includes a handrail 9, which is installed inside the sliding detection box 4 and located on the side away from the opening. The two side walls of the sliding detection box 4 have through holes for the two ends of the handrail 9 to pass through. The handrail 9 has three handrail rings 901, and three U-shaped first connecting pipes 1 pass through the handrail rings 901 respectively. Pulling the handrail 9 will simultaneously cause the sliding detection box 4 and the first connecting pipes 1 to slide together. The fixed detection box 3 and the outer side walls of the sliding detection box 4 have bolt holes. After the sliding detection box 4 and the first connecting pipes 1 are adjusted in length by sliding, they are fixedly connected to the fixed detection box 3 by fixing bolts in the bolt holes.

[0029] Work process: According to the required test tube length, pull the handle 9, which simultaneously causes the sliding test box 4 and the first connecting pipe 1 to slide, changing the length of the overlapping part of the sliding test box 4 and the fixed test box 3, and the length of the overlapping part of the first connecting pipe 1 and the second connecting pipe 2. Place the test piece 5 into the test cavity 301, plug the plug 10, turn on the cleaning device, and the cleaning fluid enters through one end of the second connecting pipe 2, and then enters the test cavity 301 through the second connecting pipe 2 and the first connecting pipe 1 in sequence, and then exits through the outlet. After cleaning, open the plug 10, take out the test piece 5, and observe the simulated object on the test piece 5. If it is clean, it is qualified; otherwise, it is unqualified.
