DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with specific drawings.

[0021] See also Figure 1 The utility model provides a throat swab stripping device, which is used to strip a throat swab packaged in a packaging bag out of the bag. It includes: a base 100, a clamping assembly 200 arranged on the base 100 and capable of clamping the packaging bag, and a throat swab stripping piece 300, wherein the throat swab stripping piece 300 can move toward the packaging bag to push the throat swab in the packaging bag out of the packaging bag. With the help of tools, the throat swab packaged in the packaging bag can be stripped out of the bag. When stripping the throat swab, it is no longer manually operated by the staff, which reduces the risk of cross infection. Moreover, the stripping is completed with the help of tools, which can reduce the workload of the staff and thus reduce the labor intensity.

[0022] The side wall of the base 100 is provided with a plurality of first weight-reducing holes 120 , and the top surface of the base 100 is provided with a plurality of second weight-reducing holes 130 . The design of the weight-reducing holes helps to reduce the weight of the stripping device itself.

[0023] The clamping assembly 200 includes a first clamping mechanism 210, the first clamping mechanism 210 includes a clamping jaw 230 that can be clamped or opened, and the clamping jaw 230 has a first activity space for the pharyngeal swab to move through after being clamped. The clamping assembly 200 also includes a second clamping mechanism 220 arranged between the first clamping mechanism 210 and the driving mechanism 320, the second clamping mechanism 220 includes a clamping jaw 230 that can be clamped or opened, and the clamping jaw 230 of the second clamping mechanism 220 has a second activity space for the pharyngeal swab to move through after being clamped. Alternatively, the clamping assembly 200 includes a first clamping mechanism 210 and a second clamping mechanism 220 arranged between the first clamping mechanism 210 and the driving mechanism 320, the first clamping mechanism 210 and the second clamping mechanism 220 both include a clamping jaw 230 that can be clamped or opened, and the clamping surface of the clamping jaw 230 is covered with an anti-slip layer, and the anti-slip layer is preferably made of rubber or silicone. The clamping jaws 230 of the first clamping mechanism 210 and the clamping jaws 230 of the second clamping mechanism 220, when closed, both have a third activity space for the pharyngeal swab to move through. The first activity space, the second activity space, and the third activity space enable the first clamping mechanism 210 and the second clamping mechanism 220 to not tightly fix the pharyngeal swab after clamping the packaging bag and the pharyngeal swab, but to leave enough activity space for the pharyngeal swab to move, so that the pharyngeal swab can be smoothly pushed out of the packaging bag.

[0024] The pharyngeal swab stripping member 300 includes a stripping push block 310 and a driving mechanism 320 for driving the stripping push block 310 to reciprocate in a direction close to or away from the clamping assembly 200. After the clamping assembly 200 clamps the packaging bag and the pharyngeal swab, the driving mechanism 320 drives the stripping push block 310 to move in the direction of the second clamping mechanism 220 to push the pharyngeal swab out of the packaging bag. The first clamping mechanism 210 and the second clamping mechanism 220 preferably use electric clamps, and the first clamping mechanism 210 and the second clamping mechanism 220 can extend the clamping path, so that the softer pharyngeal swab can always keep moving straight without bending even if it is pushed by the stripping push block 310 to avoid affecting the stripping process.

[0025] See also Figure 2The bottom of the stripping push block 310 is connected to a slide groove 110 arranged on the base 100, and the slide groove 110 is arranged along the moving path of the stripping push block 310, and the bottom end of the stripping push block 310 is slidably arranged in the slide groove 110. The stripping push block 310 driven by the driving mechanism 320 reciprocates along the slide groove 110, and the slide groove 110 can guide the stripping push block 310. When the stripping push block 310 is moved to the second clamping mechanism 220, the clamping claw 230 of the second clamping mechanism 220 opens to allow the stripping push block 310 to continue to pass, so that the stripping push block 310 continues to push the pharyngeal swab in the direction of the first clamping mechanism 210. In this way, even if a softer pharyngeal swab is pushed, the pharyngeal swab can be smoothly ejected from the packaging bag in a straight manner. After the pharyngeal swab is ejected from the bag, the packaging bag is piled up at the position of the first clamping mechanism 210, so that the packaging bag is away from the sampling end of the pharyngeal swab to avoid interference with the sampling.

[0026] The driving mechanism 320 includes a cylinder, a hydraulic cylinder or an electric push rod disposed on the base 100, the output shaft of the cylinder, the hydraulic cylinder or the hydraulic cylinder faces the clamping assembly 200, and the stripping push block 310 is disposed on the output shaft of the cylinder or the hydraulic cylinder. The stripping push block 310 can be automatically moved by driving components such as the cylinder or the hydraulic cylinder, so that in the process of ejecting the throat swab for stripping, the degree of automation is high, reducing the workload of the staff.

[0027] In one embodiment, the driving mechanism 320 includes a motor provided on the base 100, a screw 321 provided on the base 100 and capable of rotating around its own axis, and a connecting sleeve 322 screwed to the screw 321. The motor is assembled in the connecting disk 400, and the connecting disk 400 can be screwed to the mechanical arm of the sampling robot, and automatically cooperates to perform sampling after stripping the throat swab, and the shell automatically completes the sampling, saving manpower. One end of the screw 321 is connected to the output shaft of the motor, and the other end can be rotatably mounted on the base 100 after passing through the clamping assembly 200. The base 100 has two bearing mounting parts 332 adjacent to the edge of the base 100, each of which is connected to a bearing 330 through the mounting member 331, and the mounting member 331 is screwed to the bearing mounting part 332, and the two ends of the screw 321 are respectively connected to the inner rings of the two bearings 330. The friction loss is reduced by the bearing 330, so that the motor can run smoothly and stably. In order to allow the screw rod 321 to pass smoothly, each clamping jaw 230 is provided with an escape space 231 that is recessed toward the inside of the clamping jaw 230. The escape space 231 can be connected to the third activity space as a whole. The escape space 231 allows the arrangement of the screw rod 321 to not affect the normal operation of the clamping jaw 230. The connecting sleeve 322 is provided with a first connecting hole 311 that passes through the connecting sleeve 322. The screw rod 321 is assembled in the first connecting hole 311, and then the stripping push block 310 is screwed to the connecting sleeve 322 by bolts. If the stripping push block 310 is worn, it is convenient to disassemble and replace it.

[0028] The throat swab stripping device further includes a controller, and the clamping assembly 200 is electrically connected to the controller or the clamping assembly 200 and the throat swab stripping piece 300 are both electrically connected to the controller. The opening and closing of the clamping assembly 200 and the throat swab stripping piece 300 are automatically controlled by the controller, which is convenient to use and reduces the workload of the staff.

[0029] The throat swab stripping device also includes a push block sensor disposed at the second clamping mechanism 220, and the push block sensor, the second clamping mechanism 220, and the first clamping mechanism 210 are all electrically connected to the controller. The push block sensor is used to sense the distance between the stripping push block 310 and the second clamping mechanism 220, so that the controller can conveniently control the second clamping mechanism 220 to automatically open the clamping claw 230 in the second clamping mechanism 220 after the stripping push block 310 approaches, so that the stripping push block 310 continues to move.

[0030] The working principle of the throat swab stripping device is as follows: the packaging bag with the throat swab encapsulated inside is placed between the opened jaws 230 of the first clamping mechanism 210 and the second clamping mechanism 220, and the controller controls the jaws 230 to clamp the packaging bag and the throat swab, but there is a movable space between the jaws 230 for the throat swab to move. After starting the driving mechanism 320, the stripping push block 310 moves along the slide groove 110 toward the second clamping mechanism 220 until it is close to the second clamping mechanism 220. The two jaws 230 of the second clamping mechanism 220 open, allowing the stripping push block 310 to continue to push the throat swab toward the first clamping mechanism 210. The packaging bag is piled up at the position of the first clamping mechanism 210, and the throat swab is successfully pushed out of the packaging bag to complete the stripping work.

[0031] The throat swab stripping device: 1. With the help of mechanical tools, that is, the clamping assembly 200 and the throat swab stripping piece 300 cooperate with each other to complete the stripping of the throat swab. During the stripping process, manual operation of the staff is not required, which reduces the risk of cross infection, reduces the workload of the staff, and can achieve the effect of reducing labor intensity. 2. The first clamping mechanism 210 and the second clamping mechanism 220 are arranged at intervals along the arrangement direction of the slide 110, which can extend the clamping path, so that even if the stripping push block 310 pushes a softer throat swab, the throat swab can be pushed out of the packaging bag in a straight manner to prevent the throat swab from bending in the packaging bag and not being stripped out of the bag smoothly. 3. The driving mechanism 320 can be a cylinder, a hydraulic cylinder or an electric push rod, or it can be realized by a motor connected to a screw 321, which is more convenient and quick to drive the stripping push block 310. Moreover, after the controller is connected to the clamping assembly 200 and the throat swab stripping piece 300, the stripping is automatically controlled, and the work intensity is lower.
