Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to a PBS cleaning device for intestinal samples. Background Technique

[0002] PBS refers to phosphate buffered saline. PBS is a buffer solution commonly used in biological and medical research, and its main components are phosphate ions and sodium chloride. In biological experiments, PBS is often used as an additive to cell culture media, a washing buffer, a diluent, etc. PBS can be used to wash cells and culture media to remove residual culture media and impurities, thus ensuring the accuracy and reliability of experiments.

[0003] In the experiment of intestinal tissue research, before culturing and researching intestinal tissues, it is necessary to use PBS to wash intestinal samples. The existing cleaning method is usually that the experimenter puts the intestinal sample into a beaker, adds PBS to it, and then gently shakes it until there is no foam. The cleaning step usually needs to be repeated many times to achieve a qualified cleaning effect. The experimenter holds the beaker containing PBS and the intestinal sample and shakes it for cleaning. Holding the beaker for a long time will inevitably cause fatigue, and multiple cleanings consume manpower.

[0004] Therefore, we need to design such a PBS cleaning device for intestinal samples. Content of the Utility Model

[0005] In order to overcome the disadvantage of the existing cleaning method consuming manpower, the technical problem is: to provide a PBS cleaning device for intestinal samples.

[0006] The technical solution is: a PBS cleaning device for intestinal samples, including an operation box, a first motor, an eccentric shaft, a connecting plate, a spring, a placement frame, a cleaning bucket, a protective door, a second handle and a controller. The first motor is fixedly connected to the top of the operation box. The output shaft of the first motor penetrates into the operation box. The eccentric shaft is fixedly connected to the output shaft of the first motor. The connecting plate is fixedly connected to the bottom of the eccentric shaft. A plurality of springs are fixedly connected to the top of the connecting plate. The top of the springs is fixedly connected to the inner top of the operation box. The placement frame is rotatably connected between the lower parts of the connecting plate. The cleaning bucket is placed in the placement frame. The protective door is rotatably connected to the front side of the operation box. The second handle is fixedly connected to the protective door. The controller is installed on the protective door. The first motor is electrically connected to the controller.

[0007] Furthermore, it further includes a second motor. The second motor is fixedly connected to the lower part of the connecting plate. The output shaft of the second motor passes through the connecting plate and is fixedly connected to the placement frame. The second motor is electrically connected to the controller.

[0008] Furthermore, it also includes a water sprayer, a plugging block, a water pipe, and a solenoid valve. The water sprayer is fixedly connected to the top of the operation box. An inlet is provided on the front side of the water sprayer. The plugging block is slidably connected at the inlet. The bottom of the water sprayer is connected and communicated with the water pipe. One end of the water pipe penetrates into the operation box, and the other end of the water pipe is located above the cleaning bucket. A solenoid valve is installed on the upper part of the water pipe, and the solenoid valve is electrically connected to the controller.

[0009] Furthermore, it also includes a partition board, a gauze, a collection box, and a first handle. The partition board is fixedly connected to the lower side inside the operation box. The gauze is placed on the partition board. The collection box is slidably connected to the lower side inside the operation box. The collection box is located directly below the partition board. The first handle is fixedly connected to the collection box.

[0010] Furthermore, it also includes an electric push rod and a limiting plate. The electric push rod is fixedly connected to the rear side of the operation box. A rectangular opening is left on the rear side of the operation box. The rectangular opening is located above the electric push rod. The telescopic rod of the electric push rod is fixedly connected to the limiting plate. The limiting plate slides at the rectangular opening. The top of the limiting plate abuts against the upper part of the connecting plate. The electric push rod is electrically connected to the controller.

[0011] Furthermore, the edge of the gauze is fixed by the frame.

[0012] The utility model has the following advantages: 1. By setting components such as the first motor, the eccentric shaft, and the connecting plate, the first motor drives the eccentric shaft to rotate. Through the working principle of the eccentric shaft, the connecting plate is driven to make a circular motion, imitating the action of an experimenter holding a beaker and shaking, automatically cleaning the intestinal tissue, and saving labor.

[0013] 2. By setting components such as the second motor, the placement frame, and the collection box, the second motor drives the placement frame to rotate and tilt, thereby realizing the automatic dumping of the cleaning bucket to pour out the intestinal tissue. The gauze separates the intestinal tissue from the waste liquid, eliminating the need for the experimenter to manually separate and filter, saving labor and time.

[0014] 3. By setting the water sprayer, the water pipe, and the solenoid valve, the controller automatically switches the solenoid valve, and the water sprayer fills the cleaning bucket with PBS, eliminating the need for the experimenter to manually add PBS multiple times. Other experimental steps can be carried out while cleaning, effectively improving the cleaning efficiency. Description of the Drawings

The top of the limit plate 17 abuts against the upper part of the connecting plate 4. The electric push rod 16 is electrically connected to the controller 20.

[0023] As Figures 1-3As shown in the figure, it further includes a water sprayer 9, a blocking block 901, a water pipe 10, and a solenoid valve 11. The left side of the top of the operation box 1 is connected to the water sprayer 9 by bolts. The front side of the upper part of the water sprayer 9 is provided with a water inlet, and the blocking block 901 is slidably connected at the water inlet. The left side of the bottom of the water sprayer 9 is connected and communicated with the water pipe 10. One end of the water pipe 10 penetrates into the operation box 1, and the other end of the water pipe 10 is located above the cleaning bucket 8. The solenoid valve 11 is installed on the upper part of the water pipe 10, and the solenoid valve 11 is electrically connected to the controller 20.

[0024] When the intestinal samples are collected and need to be cleaned, open the blocking block 901, fill the water sprayer 9 with PBS from the water inlet, and after completion, plug the blocking block 901 back into the water inlet. Hold the second handle 19 and open the protective door 18, put the intestinal samples into the cleaning bucket 8, hold the second handle 19 and close the protective door 18. Start the electric push rod 16 through the controller 20 to push the limiting plate 17 to move backward. The limiting plate 17 no longer abuts against the connecting plate 4. Open the solenoid valve 11 through the controller 20, and the water sprayer 9 sprays PBS into the cleaning bucket 8. Close the solenoid valve 11, start the first motor 2 through the controller 20. The output shaft of the first motor 2 drives the eccentric shaft 3 to rotate. The eccentric shaft 3 transmits the revolution to drive the connecting plate 4 to make a circular motion, imitating the action of shaking a beaker by hand. At this time, the spring 5 continuously deforms, and the PBS cleans the intestinal samples. After the cleaning is completed, close the first motor 2 through the controller 20, and start the electric push rod 16 again. The telescopic rod of the electric push rod 16 drives the limiting plate 17 to move forward and reset, so as to fix the connecting plate 4 and the spring 5 resets.

The collection box 14 is located directly below the partition 12. The middle position of the front side of the collection box 14 is welded with the first handle 15.

[0027] After completing a cleaning operation, the second motor 6 is started through the controller 20. The output shaft of the second motor 6 drives the placement frame 7 to rotate clockwise by a certain angle, thereby driving the cleaning bucket 8 to tilt and pour out the intestinal samples and waste liquid in the cleaning bucket 8. At this time, the intestinal samples and waste liquid fall on the gauze 13 and the partition 12. The second motor 6 is turned off, and the intestinal samples are isolated on the gauze 13. The waste liquid flows into the collection box 14 through the round holes of the partition 12, and the waste liquid falls along the inclined surface of the partition 12, accelerating the collection of the waste liquid flow. The second motor 6 is started again through the controller 20 to drive the placement frame 7 and the cleaning bucket 8 to reset. Hold the second handle 19 and open the protection door 18. Use tools such as tweezers or directly take out the gauze 13, and put the intestinal tissue back into the cleaning bucket 8 again. Close the protection door 18. Repeating the above operations can achieve multiple cleanings. Whether to replace the gauze 13 after using it one or two times can be determined according to the situation.
