Description

Technical Field

[0001] This utility model relates to the field of instrument cleaning technology, and in particular to a device that simulates the cleaning effect of tubular instruments. Background Technology

[0002] Whether medical devices are properly cleaned directly affects the quality of subsequent disinfection and sterilization, making the monitoring of cleaning effectiveness during the cleaning process crucial. Using a cleaning effectiveness monitoring card in conjunction with a cleaning effectiveness simulation device provides a more intuitive way to monitor cleaning results, and the results are also easier to store. In recent years, the number of tubular medical devices handled by hospital sterilization supply rooms has been gradually increasing. However, most sterilization supply rooms still rely on visual inspection to monitor the cleaning effectiveness of tubular medical devices, a method that is highly subjective and unscientific. Therefore, many cleaning operators hope for a tubular cleaning effectiveness monitoring system that can replace traditional visual inspection methods for monitoring the cleaning effectiveness of tubular medical devices.

[0003] A device for simulating the cleaning effect of tubular medical devices, with publication number CN217222771U, includes an upper sleeve, a lower sleeve, and an installation tube. The upper and lower sleeves are movably connected. One end of the lower sleeve connected to the upper sleeve has a straight tube section, and the installation tube is detachably installed within the straight tube section. The inner wall of the installation tube has a recessed installation groove. By using movably connected upper and lower sleeves, and detachably fixing the installation tube within the lower sleeve, and fixing the test card through the installation groove in the installation tube, the simple and reasonable device structure allows cleaning fluid to be delivered to the test card installation tube through the sleeves during cleaning in a cleaning machine. After cleaning, the cleaning effect test card is removed for testing the cleaning quality, thus solving the problem of difficulty in monitoring the cleaning effect of tubular medical devices in existing technologies.

[0004] However, tubular instruments are divided into two types: those with two open ends and those with one blind end. Since the aforementioned patent has two open ends, when testing the cleaning effect of single-blind-end tubular instruments, additional means are required to perform a single-end sealing operation, which is cumbersome. In addition, the test card of the aforementioned patent is placed parallel to the water flow direction. Although when the water flows parallel to the surface of the test card, contaminants are more likely to be deposited, simulating the actual residual state and avoiding the water flow directly washing away the test substance, the impact effect of the water flow still needs to be evaluated when testing single-end blind tubes. The impact force of the water flow on the depth of the tube is tested to reflect the cleanliness of the end of the tube. The test card of the device cannot be adjusted in angle, resulting in poor flexibility of use. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device for simulating the cleaning effect of tubular instruments, simulating the internal cleaning environment of tubular instruments with open ends and single blind ends, with simple and quick switching operation and strong applicability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for simulating the cleaning effect of tubular instruments, comprising a simulated tube sleeve, a closed single-tube connector, and a through-tube connector. A test card mounting cavity is provided in one end of the simulated tube sleeve, and a test card fixing mechanism for fixing the test card is provided in the test card mounting cavity.

The connecting assembly is configured to enable the closed single-tube connector and the through-tube connector to respectively seal and connect to one end of the simulated tube sleeve.

[0007] Preferably, the connecting assembly includes a first connecting frame, a second connecting frame, and a third connecting frame, wherein the first connecting frame connects to the simulated tube sleeve, the second connecting frame connects to the closed single tube joint, and the third connecting frame connects to the through-pipe joint. The lower parts of the first connecting frame, the second connecting frame, and the third connecting frame are rotatably connected, and the simulated tube sleeve is slidably disposed on the first connecting frame.

[0008] Preferably, the connecting assembly includes a first connecting rib, a second connecting rib, and a third connecting rib.

One end of the first connecting rib, the second connecting rib, and the third connecting rib are fixedly connected, and the other end of the first connecting rib, the second connecting rib, and the third connecting rib are respectively connected to a simulated tube sleeve, a closed single-pipe joint, and a through-pipe joint.

[0009] Preferably, the through-pipe connector can be sealed to the end of the closed single-pipe connector away from the simulated pipe sleeve. The sealing connection can be a threaded connection or a snap-fit ​​connection.

[0010] Preferably, one end of the simulated tube sleeve is provided with an external thread, the closed single tube joint and the through-tube joint are provided with corresponding internal threads, and the end of the through-tube joint away from the simulated tube sleeve is provided with an external thread for connecting the closed single tube joint.

[0011] Preferably, the test card fixing mechanism includes a rotating sleeve and a test card mounting frame. Two rotating sleeves are fixedly spaced within the test card mounting cavity. The test card mounting frame is disposed between the two rotating sleeves. Grooves for mounting test cards are provided at both the front and rear ends of the test card mounting frame. Rotating shafts are fixedly connected to both the upper and lower ends of the test card mounting frame. The rotating shafts are rotatably connected to the rotating sleeves at their corresponding positions.

[0012] Preferably, each of the four corners of the groove is fixedly connected with a fixing screw, and one side of the test card mounting frame is provided with a mounting port that communicates with the groove.

[0013] Preferably, the lower end of the rotating shaft is provided with a threaded hole, and the rotating sleeve is provided with cross-shaped fixed holes corresponding to the threaded hole, and a fixing bolt is provided in the fixed hole to be threadedly connected to the threaded hole.

[0014] The test card mounting frame can be rotated and fixed with fixing bolts, allowing the test cards installed in the frame to be at different angles. This allows for adjustment of the water flow impact effect during the testing of single-end blind pipes, enabling the detection of the impact force of water flow on the depth of the pipe cavity to reflect the cleanliness of the cavity end, thus improving the flexibility of the device.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1.

[0027] 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.

[0028] Example 1 Please see Figure 1-3 This utility model provides a technical solution: a device for simulating the cleaning effect of tubular instruments, including a simulated tube sleeve 1, a closed single-tube connector 2, and a through-tube connector 3. A test card mounting cavity 5 is provided in one end of the simulated tube sleeve 1, and an external thread is provided on the outer periphery of the end of the test card mounting cavity 5. The closed single-tube connector 2 and the through-tube connector 3 are provided with corresponding internal threads at the external threads of the simulated tube sleeve 1. An external tube connector 4 is provided at the end of the simulated tube sleeve 1 away from the external thread and at the end of the through-tube connector 3 away from the internal thread. The external tube connector 4 is connected to the output water pipe of an external testing mechanism. By different combinations between the simulated tube sleeve 1 and the closed single-tube connector 2 and the through-tube connector 3, the internal cleaning environment of these two types of tubular instruments can be simulated. The switching operation is simple and quick, the device has strong applicability, and can simulate the internal cleaning environment of tubular instruments with two open ends and one blind end.

[0029] The end of the through-pipe connector 3 away from the simulated pipe sleeve 1 is provided with an external thread for connecting the closed single pipe connector 2, which can connect the simulated pipe sleeve 1, the through-pipe connector 3 and the closed single pipe connector 2 together in sequence, making it convenient to store.

[0030] The simulated tube sleeve 1, the sealed single-pipe connector 2, and the through-pipe connector 3 are all connected to a connecting assembly. The connecting assembly is configured to allow the sealed single-pipe connector 2 and the through-pipe connector 3 to seal one end of the simulated tube sleeve 1, respectively. The connecting assembly connects the simulated tube sleeve 1, the sealed single-pipe connector 2, and the through-pipe connector 3 together, ensuring that the sealed single-pipe connector 2 and the through-pipe connector 3 will not be lost and are easy to use.

[0031] Specifically, the connecting components in this embodiment include a first connecting rib 12, a second connecting rib 13, and a third connecting rib 14. All three connecting ribs are made of flexible rubber, preferably silicone. One end of each connecting rib is fixedly connected, and the other ends are respectively connected to the simulated tube sleeve 1, the closed single-pipe connector 2, and the through-pipe connector 3.

[0032] Rotating sleeves 8 are fixedly connected to the upper and lower sides of the test card mounting cavity 5, and a test card mounting frame 6 is set between the two rotating sleeves 8. The front and rear ends of the test card mounting frame 6 are provided with grooves for installing test cards. The upper and lower ends of the test card mounting frame 6 are fixedly connected to rotating shafts 7, and the rotating shafts 7 are rotatably connected to the rotating sleeves 8 at their corresponding positions. The test card mounting frame 6 is used to place the test card.

[0033] Each of the four corners of the groove is fixedly connected with a fixing screw 11. One side of the test card mounting frame 6 is provided with an installation port that connects to the groove. The test card is inserted into the groove of the test card mounting frame 6 through the installation port, and then the test card is positioned and installed by fixing screws 11.

[0034] The lower end of the rotating shaft 7 has a threaded hole, and the rotating sleeve 8 has a cross-shaped distribution of fixing holes 9 corresponding to the threaded hole. The fixing holes 9 are equipped with fixing bolts 10 that are threadedly connected to the threaded holes. By rotating the test card mounting frame 6 and fixing it with the fixing bolts 10, the test card installed in the test card mounting frame 6 can be at different angles. This allows for adjustment of the water flow impact effect in the detection of single-end blind pipes, realizing the function of detecting the impact force of water flow on the depth of the pipe cavity to reflect the cleanliness of the cavity end, and improving the flexibility of the device.

[0035] See Figure 4-6 When conducting simulation tests on different types of tubular instruments, the internal cleaning environment of these two types of tubular instruments can be simulated by simulating the different combinations between the sleeve 1 and the closed single tube connector 2 and the through tube connector 3.

[0036] Since the first connecting rib 12, the second connecting rib 13, and the third connecting rib 14 are all made of flexible rubber, the closed single-pipe joint 2 and the through-pipe joint 3 can be placed arbitrarily after disassembly, and can also be easily connected by threads. Figure 4 and Figure 5 The first connecting bar 12, the second connecting bar 13, and the third connecting bar 14 are not shown in the diagram.

[0037] When switching the angle of the test card in the mounting frame 6, unscrew the fixing bolt 10, rotate the rotating shaft 7 to make it rotate the mounting frame 6 by 90 degrees, and then screw the fixing bolt 10 into the threaded hole at the lower end of the rotating shaft from the fixing hole 9 on the other side to fix it, thus completing the switching and fixing of the mounting frame 6.

[0038] Example 2 See Figure 7 In this embodiment, the connecting components include a first connecting frame 15, a second connecting frame 16, and a third connecting frame 17. The first connecting frame 15 connects to the simulated tube sleeve 1, the second connecting frame 16 connects to the closed single tube connector 2, and the third connecting frame 17 connects to the through pipe connector 3. The lower parts of the first connecting frame 15, the second connecting frame 16, and the third connecting frame 17 are rotatably connected, and the simulated tube sleeve 1 is slidably set on the first connecting frame 15.

[0039] In this embodiment, the test card mounting cavity 5 has an external thread on its outer periphery. The closed single pipe connector 2 and the through pipe connector 3 have corresponding internal threads on the external threads of the simulated pipe sleeve 1. The end of the through pipe connector 3 away from the simulated pipe sleeve 1 has an external thread for connecting the closed single pipe connector 2. The simulated pipe sleeve 1, the closed single pipe connector 2, and the through pipe connector 3 can all rotate on the corresponding connecting frame.

[0040] See Figure 8 When it is necessary to connect the simulation sleeve 1 and the through pipe connector 3 for testing, remove the closed single pipe connector 2 from the through pipe connector 3, and then rotate the second connecting bracket 16 to move the closed single pipe connector 2 away from the through pipe connector 3.

[0041] See Figure 9 When it is necessary to connect the simulated tube sleeve 1 and the closed single tube connector 2, remove the closed single tube connector 2 from the through pipe connector 3, remove the through pipe connector 3 from the simulated tube sleeve 1, then rotate the third connecting bracket 17 to move the through pipe connector 3 away from the simulated tube sleeve 1, adjust the angle of the test card in the test card mounting frame 6, and finally slide the simulated tube sleeve 1 to connect the simulated tube sleeve 1 and the closed single tube connector 2 by thread.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
