Technical Field

[0001] The invention relates to the technical field of sterilization specification plates, in particular to an automatic sampling sterilization specification plate. Background Art

[0002] Sterilization specification plates are one of the essential equipment in hospitals, laboratories and other medical institutions. They are mainly used for disinfection and sterilization to ensure the cleanliness and working environment of these places. Sterilization specification plates, also known as biological indicators, are a device used to verify sterilization operations. The principle is to place the sterilization specification plate containing the biological indicator in the sterilization container for sterilization operation, and to judge whether the sterilization operation is effective by observing whether the indicator is killed.

[0003] Common sterilized specification plates have specifications of 5cm*5cm. Before sampling, prepare the sterilized specification plate and the corresponding sampling liquid or culture medium. When sampling, hold the specification plate handle and place the specification plate at the place to be tested. Use a cotton swab soaked in the sampling liquid to smear the specification plate horizontally and vertically for 5 times, and then rotate the swab to complete the sampling. Then break off the head of the cotton swab and put it into the sampling liquid for inspection. At present, the existing sterilized specification plates have cumbersome sampling steps and high requirements for the standardization of the sampling process. On the one hand, it is labor-intensive for large-scale sampling, and on the other hand, it is easy to cause distortion of test results due to non-standard sampling process.

The axis of the plug-in ring is tilted, and when the cotton swab is inserted, its head also remains tilted. This installation method can make the cotton swab head contact the sampling position laterally during sampling, with a larger contact area, and it is also easier to make the cotton swab head rotate during sampling.

[0019] 3.

The sealing ring can ensure the sealing between the rotary self-resetting cover and the sampling liquid bottle. The double sealing ring structure has better sealing performance and can better protect the sampling liquid from contamination.

[0020] 4. In the present invention, the sealing cover and the access window are set to be transparent, so as to facilitate observation of the working status of the device and avoid sampling failure due to failure to be discovered in time during machine operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1 to 11 An automatic sampling and sterilization specification plate comprises a contact specification bottom plate 1, the contact specification bottom plate 1 is set as a frame-shaped structure and has a 5*5CM sampling port inside, a sealing cover 2 is arranged above the contact specification bottom plate 1, a micro three-axis moving mechanism 6 is installed in the sealing cover 2, a top box 5 is arranged above the sealing cover 2, a control chip and a battery are arranged in the top box 5, the control chip is used to control the automatic movement of the micro three-axis moving mechanism 6, and the battery is used to power the chip and the control chip; the micro three-axis moving mechanism 6 comprises an X-axis slide 7, and a slider of the X-axis slide 7 is fixed on the slider A Y-axis slide 8 is installed, and a Z-axis slide 9 is fixedly installed on the slider of the Y-axis slide 8; a cotton swab clamping mechanism 13 for clamping a cotton swab 11 is installed on the slider of the Z-axis slide 9, a handle 4 is provided on one side wall of the sealing cover 2, and an outwardly protruding access window 3 is provided on the other side wall of the sealing cover 2, and a window cover 20 is rotatably connected to the access window 3, and a plurality of sampling liquid bottles 21 are placed side by side in the access window 3, and a rotating self-resetting cover 30 is provided on the top of the sampling liquid bottle 21, and a push cover top plate 10 for pushing open the rotating self-resetting cover 30 is provided at the bottom of the Z-axis slide 9.

[0036] Working principle of this embodiment:

[0037] When the device is ready for operation in this embodiment, the user first places the contact specification base plate 1 containing the biological indicator in the area to be detected, and then starts the entire sampling process through the control chip. The control chip starts the micro three-axis moving mechanism 6, which is composed of an X-axis slide 7, a Y-axis slide 8, and a Z-axis slide 9, to ensure that the cotton swab clamping mechanism 13 can accurately move to the top of the 5*5CM sampling port inside the contact specification base plate 1. In order to ensure that the cotton swab is not contaminated, the cotton swab is unpacked and placed at the access window 3 when used, and is clamped by the cotton swab clamping mechanism 13. The cotton swab clamping mechanism 13 clamps the cotton swab 11 and moves it to the position of the sampling liquid bottle 21 through the coordinated action of the electric telescopic rod 17 and the rotating steering gear 18. The push cover top plate 10 at the bottom of the Z-axis slide 9 pushes open the rotary self-resetting cover 30, and the cotton swab 11 extends into the sampling liquid bottle 21 to dip the sampling liquid, and then the cotton swab 11 is pulled out. When the push cover top plate 10 moves away, the rotary self-resetting cover 30 automatically resets and keeps the seal again. The three-axis moving mechanism 6 uses the cotton swab soaked in the sampling liquid to smear the specification plate horizontally and vertically for 5 times each. After the sampling is completed, the cotton swab clamping mechanism 13 transfers the cotton swab to the top of the sampling liquid bottle 21 in the access window 3. At this time, the Z-axis slide 9 drives the cover pusher top plate 10 to descend, and opens the rotary self-resetting cover 30. The cotton swab clamping mechanism 13 translates the cotton swab 11 after the cotton swab 11 is inserted into the sampling liquid bottle 21. Since the rod of the sampling cotton swab 11 has a notch for easy breaking, the translation causes the head of the cotton swab 11 to break and release it into the sampling liquid bottle, completing the sample collection. After completing the sampling and collection, the micro three-axis moving mechanism 6 resets to the initial position, waiting for the next operation instruction or manually shutting down the device.

[0038] This embodiment simplifies the cumbersome steps of traditional manual sampling through automated control, reduces labor intensity, improves the standardization and consistency of sampling, and reduces the problem of distortion of test results caused by improper human operation; the sampling process is carried out in the sealed cover 2, which effectively prevents the influence of external pollution on the sample and ensures the accuracy of the sampling results; the design of the rotary self-resetting cover 30 makes the sample collection process more convenient and faster, and the sampling liquid bottle 21 can remain sealed to avoid exposure of the sampling liquid. Therefore, this embodiment provides a more efficient, accurate and safe solution for the disinfection and sterilization work of medical institutions and laboratories.

[0040] In this embodiment, the rod of the cotton swab 11 is plugged into the cotton swab rod socket 15 before sampling. When the head of the cotton swab contacts the sampling position and translates, the head of the cotton swab 11 rotates accordingly, thereby achieving a good sampling effect.

[0042] In this embodiment, the axis of the plug-in ring 16 is tilted, and when the cotton swab 11 is inserted, its head also remains tilted. This installation method can make the head of the cotton swab 11 contact the sampling position laterally during sampling, with a larger contact area, and it is also easier to rotate the cotton swab head during sampling.

A clamp 19 is fixedly connected to the rotating rod of the rotating servo 18, and the clamp 19 is used to clamp the rod of the cotton swab 11.

[0044] In this embodiment, the steering gear 18 is rotated to drive the clamping claw 19 to clamp the rod of the cotton swab 11, and the electric telescopic rod 17 drives the cotton swab 11 to rise and fall slightly, so as to achieve the connection and removal of the rod of the cotton swab 11 and the plug-in ring 16.

[0046] In this embodiment, the insertion hole 22 is plugged into the fixed insertion platform 23 to ensure the stability of the sampling liquid bottle 21.

[0049] Example 7: Please refer to Fig.11 , an automatic sampling sterilization specification plate, which is different from Example 1 in that a sealing ring 31 is provided on the lower surface of the rotating self-resetting cover 30.

[0050] The sealing ring 31 is configured as a double sealing ring structure with inner and outer concentricities.
