The rotating disk 30 can be driven to rotate by starting the second motor 37. The rotating disk 30 can adjust the positions of multiple collection cups 8 during the rotation process so that they can be received in sequence.

[0042] The outer wall of the extension tube 26 is fixedly sleeved with a top cover 27, and a rectangular hole is opened on the top of the top cover 27, which is used to make way for the outer collection cup 8 and seal the top of the remaining collection cups 8. Two sets of fixed blocks 32 are fixedly provided on the top of the top cover 27, and a guide rod 34 is fixedly provided between the two corresponding fixed blocks 32. The outer wall sliding sleeve of the guide rod 34 is provided with a second sliding block 33, and a movable cover 28 is fixedly provided between the two second sliding blocks 33, which is used to seal the top of the outer collection cup 8. The outer wall of the guide rod 34 is sleeved with a first spring 35, and the two ends of the first spring 35 are respectively fixedly connected to the side close to each other of one of the fixed blocks 32 and the second sliding block 33, which is used to drive the movable cover 28 to reset. The top of the collection cup 8 is fixedly sleeved with an arc plate 36, and multiple arc plates 36 form a complete circle, which is used to seal the bottom end of the extension tube 26 during the adjustment process.

[0043] The control component specifically includes a first conductive block 46 fixedly arranged on the top of the base 7, a sliding column 48 is slidably provided on the top of the first conductive block 46, a second conductive block 47 is fixedly arranged on the top of the sliding column 48, and the second conductive block 47 is used in conjunction with the inner cylinder 41. A third spring 49 is arranged in the base 7, and the two ends of the third spring 49 are respectively fixedly connected to the mutually adjacent sides of the sliding column 48 and the base 7. A second spring 42 is sleeved on the outer wall of the inner cylinder 41, and the two ends of the second spring 42 are respectively fixedly connected to the mutually adjacent sides of the inner cylinder 41 and the collection cup 8. When there is a lot of vomit in the inner cylinder 41, the process of downward movement under the action of gravity can drive the second conductive block 47 to contact the first conductive block 46 and turn on the power of the second motor 37.

[0044] The outer wall of the inner cylinder 41 is fixed with a positioning column 38, the guide ring 29 is provided with an annular groove 43, the inner wall of one side of the guide ring 29 is provided with a vertical groove 44 connected with the annular groove 43, and the outer wall of the rotating disk 30 is provided with a plurality of rectangular openings corresponding to the vertical grooves 44 for taking out and replacing the collecting cup 8. The outer wall of the guide ring 29 is provided with a vertical hook groove 45 connected with the annular groove 43, which is used to drive the inner cylinder 41 to reset upward after descending, so that it drives the second conductive block 47 away from the first conductive block 46, and disconnects the power supply of the second motor 37.

[0045] A positioning ring 31 is fixedly provided on the outer wall of the collecting cup 8, and at least one positioning pin 39 is fixedly provided on the bottom of the positioning ring 31. A positioning hole 40 corresponding to the positioning pin 39 is opened on the top of the rotating disk 30 for positioning the collecting cup 8, so that the collecting cup 8 will not rotate during the adjustment process, thereby preventing the sliding column 48 from disengaging from the annular groove 43.

[0046] A battery 9 is also provided in the cart 1, and the battery 9 is connected to the controller 6, the lifting mechanism, the adjustment component and the sampling mechanism through a wire for powering them. The controller 6 is arranged on one side of the cart 1, so that the operator can control it conveniently.

[0047] When the vomit collection device for oncology nursing is used, the device is pushed to the patient. When the patient wants to vomit, he or she directly vomits into the receiving tube 2, and then is guided by the hose 21 and the first connecting tube 4 to flow into the collection box 5 for collection. At the same time, part of the vomit will enter the collection cup 8 and the inner tube 41 through the extension tube 26. At the same time, the weight of the vomit can drive the inner tube 41 to move downward, compress the second spring 42, and drive the positioning column 38 to move downward in the vertical hook groove 45. The downward movement of the inner tube 41 can drive the second conductive block 47 to move downward. When the second conductive block 47 contacts the first conductive block 46, the second motor 37 can be started by the controller 6. The second motor 37 can drive the rotating disk 30 to rotate. The rotation of the rotating disk 30 can adjust the plurality of collection cups 8. The collecting cup 8 can drive the inner cylinder 41 to move during the movement. During the movement of the inner cylinder 41, the inner cylinder 41 can move upward under the action of the positioning column 38 and the vertical hook groove 45, and can drive the positioning column 38 to move into the annular groove 43. At this time, the inner cylinder 41 is away from the second conductive block 47, and the second conductive block 47 can be reset upward under the action of the third spring 49 and away from the first conductive block 46. When the first conductive block 46 is powered off, the second motor 37 can be started by the delay switch until the subsequent collecting cup 8 moves to the bottom of the extension tube 26 to continue to receive the sample. During the movement of the collecting cup 8, the arc plate 36 can be used to seal the bottom end of the extension tube 26 to prevent vomitus from being discharged from the extension tube 26. At the same time, the top of the collecting cup 8 can be sealed by the top cover 27.

[0048] When the collection cup 8 containing vomitus moves to the outside, the movable cover 28 is pushed inward to expose the corresponding arc plate 36. At this time, the positioning column 38 corresponds to the vertical groove 44, and then the collection cup 8 is pulled upward to drive the collection cup 8 to separate from the rotating disk 30, and a new collection cup 8 is replaced to receive the vomitus in turn.

[0049] When the height of the receiving tube 2 needs to be adjusted, the first motor 22 is started by the controller 6, and the first motor 22 can drive the corresponding second gear 23 to rotate, and the rotation of the second gear 23 can drive the gear plate 20 to rotate, and the rotation of the gear plate 20 can drive the other two second gears 23 to rotate, so that the second screw 24 and the third screw 25 can be driven to move upward at the same time, and the second screw 24 and the third screw 25 can drive the connecting block 12 and the mounting plate 16 to move upward during the upward movement, so that they can drive the receiving tube 2 to move upward;

[0050] When it is necessary to adjust the receiving tube 2 to tilt toward the patient, start the motor 19, the motor 19 can drive the first screw 17 to rotate, the rotation of the first screw 17 can drive the first sliding block 18 to move, and the first sliding block 18 can drive the receiving tube 2 to tilt through the connecting rod 15 during the movement, and the first rotating seat 11 can be driven to rotate on the connecting block 12 during the tilting of the receiving tube 2. At the same time, the guide plate 3 can be driven to rotate through the two meshing first gears 13 during the rotation until the guide plate 3 is perpendicular to the receiving tube 2. At this time, the guide plate 3 extends to the patient's chin, and the vomitus of the patient can flow downward under the guidance of the guide plate 3 and the receiving tube 2 during vomiting.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
