Description

Technical Field

[0001] This application relates to the field of sterilization testing technology, and more specifically, to a sterilization effectiveness testing device. Background Technology

[0002] Wastewater generated by biosafety laboratories contains highly active pathogenic microorganisms (such as viruses, bacterial spores, drug-resistant bacteria, etc.) and must be sterilized before it can be discharged.

[0003] A search revealed that Chinese patent CN213865447U discloses a high-efficiency sterilization tank for biosafety laboratory wastewater. When the device heats the wastewater to be sterilized in the inner tank, on the one hand, a portion of the steam enters the jacket from the first steam inlet pipe to heat the inner tank, thereby achieving the purpose of indirect heating of the sterilized wastewater; on the other hand, the steam also enters the inner tank through the second steam inlet pipe and the dispersing and stirring device to directly heat the sterilized wastewater, achieving the purpose of rapid and efficient sterilization.

[0004] During the sterilization process using sterilization tanks, it is necessary to periodically test the sterilization effect of the sterilization tanks. This requires the use of testing tools to place containers containing bacteria into the sterilization tanks. However, the gap between the top of the sterilization tanks placed indoors and the ceiling is small, making it difficult for the testing tools to place the containers containing bacteria into the deeper parts of the sterilization tanks. In view of this, we propose a sterilization effect testing device. Utility Model Content

[0005] 1. Technical problems to be solved The purpose of this application is to provide a sterilization effect testing device to solve the problems mentioned in the background art.

[0006] 2. Technical Solution This application is achieved through the following technical solution: A sterilization effect testing device includes a mounting plate with multiple testing rods arranged vertically below it. The mounting plate is fixedly mounted on the uppermost testing rod. Adjacent testing rods are rotatably connected by hinges, which are located on opposite sides of the testing rods. Each testing rod has a placement groove, which is located on a different side of the testing rod, along with the hinge. A baffle is mounted on the outside of the placement groove.

[0007] As an optional solution to the technical solution of this application, the hinge includes a rotating sleeve and a rotating shaft. The rotating sleeve and the rotating shaft are respectively connected and fixed to two adjacent detection rods. The rotating shaft is inserted into the rotating sleeve and rotatably connected to the rotating sleeve. A nut is threadedly connected to the end of the rotating shaft.

[0008] As an optional solution to the technical solution of this application, the baffle is rotatably connected to the detection rod, and the connection point between the baffle and the detection rod is located above the placement groove. Except for the uppermost detection rod, the upper part of all the detection rods is fixed with a first limiting post. The lower part of the baffle is provided with a slot. In two adjacent detection rods, the slot of the baffle on the upper detection rod engages with the first limiting post on the lower detection rod.

[0009] As an optional solution to the technical solution of this application, a second limiting post is fixedly connected to the detection rod located at the bottom, and the slot of the baffle on the detection rod located at the bottom engages with the second limiting post.

[0010] As an optional solution to the technical solution of this application, the detection rod includes a telescopic sleeve, a telescopic rod and an adjusting screw. The telescopic rod is slidably inserted into the telescopic sleeve, and the adjusting screw is threadedly connected to the telescopic sleeve.

[0017] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0018] Please see Figure 1 and Figure 2 This application provides a sterilization effect testing device, including a mounting plate 1. A plurality of testing rods 2 are provided below the mounting plate 1. The plurality of testing rods 2 are arranged in sequence in the vertical direction. The mounting plate 1 is fixedly installed on the uppermost testing rod 2. Adjacent testing rods 2 are rotatably connected by hinges 3. The two adjacent hinges 3 are respectively located on opposite sides of the testing rod 2. A placement groove 201 is provided on the testing rod 2. The placement groove 201 and the hinges 3 are respectively located on different sides of the testing rod 2. A baffle 4 is provided on the outside of the placement groove 201. The baffle 4 is installed on the testing rod 2.

[0019] In this technical solution, the user can fold two adjacent detection rods 2 using the hinge 3. Since the two adjacent hinges 3 are located on opposite sides of the detection rods 2, multiple detection rods 2 can be folded in an S-shape. When space is limited, the detection rods 2 can be rotated sequentially from the bottom to a vertical position. When testing the sterilization effect of the sterilization tank, a container containing bacteria is placed in the placement slot 201, and the placement slot 201 is blocked by the baffle 4 to prevent the container containing bacteria from falling out of the placement slot 201. By sequentially unfolding the detection rods 2, the container containing bacteria can be placed at different depths inside the sterilization tank even in space-constrained conditions. After the sterilization tank has undergone normal sterilization, the detection rods 2 are removed, and the container containing bacteria is taken off. By testing the survival of bacteria in the container, the sterilization effect of the sterilization tank can be tested.

[0020] like Figure 2As shown, the hinge 3 includes a rotating sleeve 301 and a rotating shaft 302. The rotating sleeve 301 and the rotating shaft 302 are respectively connected and fixed to two adjacent detection rods 2. The rotating shaft 302 is inserted into the rotating sleeve 301 and rotatably connected to the rotating sleeve 301. A nut 303 is threadedly connected to the end of the rotating shaft 302. In this solution, the user can connect any number of detection rods 2 to adapt to the testing of sterilization effect in sterilization tanks of different heights.

[0021] In a preferred embodiment of this application, the baffle 4 is rotatably connected to the detection rod 2. The connection point between the baffle 4 and the detection rod 2 is located above the placement slot 201. Except for the uppermost detection rod 2, all of its upper parts are fixed with a first limiting post 202. The lower part of the baffle 4 is provided with a slot 401. In two adjacent detection rods 2, the slot 401 of the baffle 4 on the upper detection rod 2 engages with the first limiting post 202 on the lower detection rod 2. When two adjacent detection rods 2 are rotated to a vertically aligned state via the hinge 3, the baffle 4 on the upper detection rod 2 can be rotated so that the slot 401 on the baffle 4 can engage with the first limiting post 202 on the lower detection rod 2. This not only blocks the placement slot 201 but also fixes the two adjacent detection rods 2, increasing the compactness of the device structure.

[0022] like Figure 3 As shown, a second limiting post 203 is fixedly connected to the bottommost detection rod 2, and the slot 401 of the baffle 4 on the bottommost detection rod 2 engages with the second limiting post 203. In this design, the baffle 4 on the bottommost detection rod 2 can engage with the second limiting post 203 through the slot 401, thereby sealing the placement slot 201.

[0023] like Figure 4 As shown, the detection rod 2 includes a telescopic sleeve 204, a telescopic rod 205, and an adjusting screw 206. The telescopic rod 205 is slidably inserted into the telescopic sleeve 204, and the adjusting screw 206 is threadedly connected to the telescopic sleeve 204. The placement groove 201 and the baffle 4 are both provided on the telescopic rod 205. On two adjacent detection rods 2, the telescopic rod 205 in the upper detection rod 2 is connected to the telescopic sleeve 204 in the lower detection rod 2 via a hinge 3. In this design, the user can adjust the relative position of the telescopic sleeve 204 and the telescopic rod 205 by adjusting the adjusting screw 206, thereby changing the length of the detection rod 2 and adjusting the spacing of the slots 401 to increase or decrease the detection density.

[0024] As a preferred embodiment of this application, at least one detection rod 2 is provided with not less than one temperature probe 5, and a display screen 6 is fixedly installed on the mounting plate 1. The display screen 6 can display the detection temperature of the temperature probe 5 and time information, so as to facilitate the user to monitor the temperature inside the sterilization tank and monitor the residence time of the container containing bacteria in the placement tank 201 inside the sterilization tank.
