[0039] The drive assembly 40 is used to control the rotation of the rotating cylinder 30.

[0040] The sampling mechanism 50 is provided in a plurality of numbers, and the plurality of sampling mechanisms 50 are arranged one-to-one corresponding to the plurality of guide grooves 741. The sampling mechanism 50 includes a guide rod 51, a sliding block 52, a spring 53, a lifting block 54, a sampling cylinder 55, a piston 56, a piston rod 57 and a pull plate 58. The guide rod 51 is arranged on the outside of the rotating cylinder 30 in the longitudinal direction and is fixedly connected at both ends with the rotating cylinder 30. The sliding block 52 is arranged on the guide rod 51 and is slidably connected with the guide rod 51. The spring 53 causes the sliding block 52 to have a tendency to move upward. The lifting block 54 is fixedly installed on the sliding block 52, and the top of the lifting block 54 is formed with a first horizontal surface 541 extending horizontally and a first inclined surface 542 inclined downward. The sampling cylinder 55 is arranged on the side of the lifting block 54 in the longitudinal direction and is inserted with the lifting block 54, specifically, the outer peripheral surface of the sampling cylinder 55 is fixedly installed with an insertion block 551, and the lifting block 54 is provided with an insertion groove 543 adapted to the insertion block 551, and the sampling cylinder 55 and the lifting block 54 are inserted through the cooperation of the insertion block 551 and the insertion groove 543. The bottom of the sampling cylinder 55 is fixedly installed with a liquid inlet pipe 552, and the liquid inlet pipe 552 communicates with the inside of the sampling cylinder 55. The piston 56 is arranged in the sampling cylinder 55, and the piston 56 is in sliding contact with the inner wall of the sampling cylinder 55 and is kept sealed. The pull plate 58 is fixedly installed on the top of the piston rod 57 in the transverse direction.

[0041] The guide plate 60 is arranged on the outside of the rotating cylinder 30 and is fixedly connected with the top plate 20 through a connecting plate 63. The bottom of the guide plate 60 is formed with a second horizontal surface 61 extending horizontally and a second inclined surface 62 inclined upward, and the second inclined surface 62 is adapted to the first inclined surface 542.

[0042] When the first horizontal surface 541 is in contact with the second horizontal surface 61, the lifting assembly 70 is used to control the upward movement of the pull plate 58.

[0043] In the initial state, the spring 53 is in the elongated state, the slider 52 and the lifting block 54 are located at the top of the guide rod 51, and the piston 56 is located at the bottom of the inner wall of the sampling cylinder 55.

[0044] The specific sampling operation steps of the device are as follows:

[0045] Firstly, the medical staff places the device on the ground near the vomit.

[0046] Then, the driving assembly 40 works, the driving assembly 40 controls the rotation of the rotating cylinder 30, and the adjacent sampling mechanism 50 on the rotating cylinder 30 will first interact with the guide plate 60. The specific interaction process is that the first inclined surface 542 on the lifting block 54 will first contact the second inclined surface 62 on the guide plate 60. With the continuous rotation of the rotating cylinder 30, under the guidance of the second inclined surface 62, the slider 52 and the lifting block 54 will drive the sampling cylinder 55 to move downward until the liquid inlet pipe 552 extends into the vomit. At this time, the first inclined surface 542 is out of contact with the second inclined surface 62, the first horizontal surface 541 is in contact with the second horizontal surface 61, the driving assembly 40 controls the rotating cylinder 30 to stop rotating, and the spring 53 is in the compressed state.

[0047] Next, the lifting assembly 70 works, the lifting assembly 70 drives the pull plate 58, the piston rod 57 and the piston 56 to move upward, at this time the negative pressure formed in the sampling cylinder 55 will suck the vomit into the sampling cylinder 55, thereby automatically completing the sampling of the vomit.

[0048] Finally, the driving assembly 40 controls the rotating cylinder 30 to continue rotating until the first horizontal surface 541 is out of contact with the second horizontal surface 61. At this time, under the action of the spring 53, the slider 52 and the lifting block 54 will return to the top of the guide rod 51. The medical staff can paste a label on the sampling cylinder 55 to record the time information and identity information of the sampled vomit. The medical staff can take away the sampling cylinder 55 in time, or can take away the sampling cylinders 55 after sampling respectively.

[0049] As can be seen from the above steps, the sampling process of the device is automatically completed, and the medical staff only needs to place the device on the ground near the vomit, without the need for excessive human intervention, thereby reducing the risk of infection. In the device, the sampling cylinder 55 is located outside the device and is inserted through the cooperation of the plug 551 and the slot 543, so it is very easy to replace the sampling cylinder 55.

[0050] It is worth mentioning that the device has a plurality of sampling mechanisms 50, when one sampling cylinder 55 completes sampling, the driving assembly 40 can control the rotating cylinder 30 to continue rotating, so that the next sampling cylinder 55 can continue sampling, thereby realizing continuous sampling. The staff can judge whether the sampling cylinder 55 has completed the sampling operation by observing whether the piston rod 57 is pulled up.

[0051] In one embodiment, the lifting assembly 70 comprises a movable rod 71, a limiting block 72, a guide shaft 73, a guide piece 74 and a first motor 75.

[0052] The movable rod 71 passes through the connecting plate 63 in the longitudinal direction and is in sliding connection with the connecting plate 63. The limiting block 72 is fixedly installed at the bottom of the movable rod 71, and a T-shaped slot 721 is formed in the limiting block 72 and communicates with the bottom of the limiting block 72 in the transverse direction. The T-shaped slot 721 is adapted to the pull plate 58 and the piston rod 57. The guide shaft 73 is arranged above the connecting plate 63 in the transverse direction and is connected with the movable rod 71. The first end of the guide piece 74 is in rotational connection with the top plate 20, and the second end of the guide piece 74 is provided with a guide slot 741 which passes through in the transverse direction. The inner wall of the guide slot 741 is in contact with the guide shaft 73. The first motor 75 is fixedly installed on the top plate 20 and is electrically connected with the controller. The first motor 75 is used to control the rotation of the first end of the guide piece 74.

[0053] When the first horizontal surface 541 is in contact with the second horizontal surface 61, the pull plate 58 and the piston rod 57 are just located in the T-shaped slot 721, and at this time, the lifting assembly 70 works.

[0054] When the lifting assembly 70 works, the controller controls the first motor 75 to start, and the first motor 75 drives the first end of the guide piece 74 to rotate, and the second end of the guide piece 74 swings upward, and the guide shaft 73 moves in the guide slot 741 and drives the movable rod 71 to move upward, and the limiting block 72 drives the pull plate 58, the piston rod 57 and the piston 56 to move upward, thereby realizing sampling operation.

[0055] After the sampling operation is completed, the driving assembly 40 controls the rotating cylinder 30 to continue rotating, and the pull plate 58 and the piston rod 57 are automatically separated from the T-shaped slot 721.

[0056] The structure of the lifting assembly 70 is simple and ingenious, which is convenient for production and manufacturing, and does not hinder and affect the rotation of the rotating cylinder 30.

[0057] In one embodiment, the guide shaft 73 is in rotational connection with the movable rod 71, and the guide shaft 73 is in rolling contact with the inner wall of the guide slot 741.

[0058] When the lifting assembly 70 starts, the second end of the guide piece 74 swings upward, and the guide shaft 73 rolls in the guide slot 741 in a natural manner and drives the movable rod 71 to move upward.

[0059] This design can reduce the friction between the guide shaft 73 and the inner wall of the guide groove 741, so that the operation of the device is more smooth.

[0060] In one embodiment, the guide shaft 73 is fixedly installed with a baffle 76, which is used to prevent the guide shaft 73 from being detached from the guide groove 741, so as to improve the stability of the device.

[0061] In one embodiment, the driving assembly 40 includes a gear ring 41, a second motor 42 and a gear 43. The gear ring 41 is fixedly installed on the inner wall of the rotating cylinder 30. The second motor 42 is fixedly installed on the base 10 and electrically connected with the controller. The gear 43 is fixedly installed on the second motor 42 and engaged with the gear ring 41.

[0062] When the driving assembly 40 works, the controller controls the second motor 42 to start, which drives the gear 43 to rotate. Under the engagement of the gear 43 and the gear ring 41, the gear ring 41 drives the rotating cylinder 30 to rotate.

[0063] In one embodiment, the outer circumferential surface of the rotating cylinder 30 is provided with a plurality of longitudinal sliding grooves 32, and the guide rod 51 and the sliding block 52 are located in the sliding grooves 32.

[0064] This hidden design can further reduce the size of the device, so as to be more convenient to carry and use.

[0065] In one embodiment, the spring 53 is sleeved on the guide rod 51, the first end of the spring 53 is fixedly connected with the inner wall of the sliding groove 32, and the second end of the spring 53 is fixedly connected with the sliding block 52.

[0066] In this way, the stability of the spring 53 can be improved, and the bending of the spring 53 when compressed can be avoided, further improving the stability of the device.

[0067] In one embodiment, the inlet pipe 552 is provided with a sheath 553, and the sheath 553 is threadedly connected with the inlet pipe 552. Before the sampling operation is performed, the medical staff can remove the sheath 553, and after the sampling is completed, the sheath 553 can be installed.

[0068] In one embodiment, the top plate 20 is fixedly installed with a handle 21, so as to facilitate carrying the device.
