Description
Technical Field
[0001] This invention relates to the field of sampling device technology, specifically to a sampling device and method for medical testing. Background Technology
[0002] The sampling device is the core mechanical structure for achieving accurate sample collection, transportation, and preprocessing. Its stability directly determines the reliability of test results. The fully automated nucleic acid sampling machine, with its integrated mechanical transmission and adaptive sampling depth adjustment, can replace manual labor in the automated collection and dispensing of nucleic acid samples, greatly improving the efficiency and standardization of medical testing and reducing the risk of cross-infection.
[0003] Currently, existing fully automated nucleic acid sampling machines require the user to open their mouth while the machine inserts a swab into their mouth for sampling. Although the swabs are changed after each user, the user's breath remains on the electric gripper, posing a risk of cross-infection and safety hazards. Furthermore, while the machine is typically equipped with an emergency stop button to prevent malfunctions, these buttons require regular maintenance to avoid potential failures. Therefore, relying solely on the emergency stop button cannot guarantee the user's safety and also presents certain safety risks.
[0004] In light of the above issues, it becomes clear that existing medical testing sampling devices on the market cannot simultaneously avoid the problems mentioned above. Even if they can be solved, they require external tools, thus failing to achieve the desired results. Therefore, we propose a medical testing sampling device and method. Summary of the Invention

[0014] Preferably, a T-shaped groove is provided on one side of the sampling machine body, and a T-shaped slider is slidably connected inside the T-shaped groove. The upper surface of the T-shaped slider is fixedly connected to the bottom surface of the sliding plate.
[0015] A method for using a medical testing sampling device includes the following steps: S1: When the equipment needs to be used, the person to be tested should be positioned directly in front of the sampling machine body, with one hand placed above the sliding plate and the other hand placed on the left side of the sampling machine body. The sampling machine body will then move, driving the gripping structure to extend into the replacement frame and replacement rubber sleeve behind the rectangular frame. It's important to understand that there are two replacement frames and two replacement rubber sleeves inside the rectangular frame. The rear replacement rubber sleeve is in a free and unlocked state, while the front replacement frame is in a locked state. Therefore, the mechanical gripper will fit onto the rear replacement rubber sleeve. Then, when the mechanical gripper is in the clamping state, it can... The mechanical gripper deforms and clamps the replacement rubber sleeve, then withdraws directly from the rectangular frame and picks up a cotton swab from the rear swab compartment for oral sampling. The gripper then moves the sampled swab to a test tube inside the test tube rack. The swab tip is inserted into the test tube, and the swab is broken off at the test tube inlet to drop the swab into the tube, completing the sampling. The gripper then pushes the replacement frame and replacement rubber pad into place. Note that during this repositioning process, the gripper continuously applies force to the replacement frame and replacement rubber pad. The rubber pad continues to move downwards. Under the thrust, the bullseye bearing retracts into the rectangular frame due to the ramp at the edge of the rectangular hole, driving one toothed plate to move. The meshing function of the toothed plate with the first gear drives another toothed plate to move, thus pulling the other bullseye bearing out of the circular locking hole inside the front replacement frame. At this time, the front replacement frame moves upwards under the force of the first force spring until the mechanical gripper continues to push the rear replacement frame downwards until the circular locking hole is aligned with the rear bullseye bearing. At this point, the bullseye bearing resets under the action of the spring return shaft, locking the rear bullseye bearing into place. Inside the circular locking hole, the front replacement frame moves to a position symmetrical to the rectangular hole and the bullseye bearing under the action of the first force spring. Therefore, the front bullseye bearing cannot be locked into the circular locking hole to limit and fix the front replacement frame. Then, the mechanical gripper can clamp the front replacement frame for the next inspection. This ensures that the same replacement frame will not be inspected twice in a row. Afterward, the ultraviolet germicidal lamp will sterilize the replacement rubber sleeve and the replacement frame. It should be noted that the replacement rubber sleeve and the replacement frame are made of transparent material, which can be effectively sterilized by the ultraviolet germicidal lamp. S2: When it is necessary to check the sealing performance of the replacement rubber sleeve and observe whether it is damaged, the control logic only needs to be set in advance through the controller. When damage detection is required, the stepper motor will run every time the mechanical gripper checks and replaces the replacement rubber sleeve. The stepper motor can drive the long shaft and the rotating plate to rotate until the rotating plate rotates 90 degrees and covers the upper surface of the rectangular frame. The surface of the rotating plate is covered with a layer of rubber. Under the action of the rubber, the gas generated by the air pump during operation will not leak. Then the air pump will draw outside air into the air pump through the air extraction pipe and output it through the bidirectional output pipe. When inspecting one of the replacement rubber sleeves, it's important to understand that to test which side of the replacement rubber sleeve, the solenoid valve on the corresponding side must be opened while the other side is closed. The air pump should operate at a low gas flow rate. If the replacement rubber sleeve is undamaged, it should still be able to move the circular plate and trigger the button, even with a large accumulation of gas in the bidirectional air outlet and inside the sleeve. This indicates that the replacement rubber sleeve on that side is properly sealed. Conversely, if it is damaged, the mechanical grippers can be opened to remove the replacement rubber sleeve covering it, allowing you to pick up and use the spare rubber sleeve. S3: When the mechanical gripper malfunctions, the subject's hand is on the sliding plate. Under the influence of physiological reflex, the subject will quickly press the pressing shaft, and both hands will apply pushing force to the sliding plate and the sampler body. After the pressing shaft is pressed down, the groove on the surface of the pressing shaft will move to one side of the sensing block. Under the action of the third force spring, the sensing block can spring into the groove. At this time, the fixing shaft fixed at one end of the sensing block will disengage from the inside of the sampler body. Therefore, the sliding plate is not subject to any limit at this time. When the pressing shaft moves downward, it will trigger the emergency stop button, which will also control the mechanical gripper to stop. Even if the emergency stop button fails, the subject will still apply pushing force to the sliding plate under the influence of physiological reflex, thus pushing the mechanical gripper physically away from the subject's mouth, providing a double protection.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention, by setting up a disinfection unit, uses a replacement frame and a replacement rubber sleeve in the disinfection unit to protect the two clamps in the mechanical gripper. After each patient's oral cavity is sampled, the replacement frame and replacement rubber sleeve are replaced to avoid the problem of cross-infection.
[0017] 2. This invention incorporates a leak-proof unit, which can perform sealing tests on the replacement rubber sleeve and replacement frame. If a hole is found in the replacement rubber sleeve, a spare rubber sleeve and a spare replacement frame will be automatically replaced, thus preventing the mechanical gripper from continuously using a damaged replacement rubber sleeve, which could lead to pathogens adhering to the surface of the mechanical gripper.
[0018] 3. This invention provides effective protection for patients by setting up a dual protection mechanism, avoiding mechanical injury. By setting up a disinfection unit, a leak-proof unit, and a dual protection mechanism, it can effectively prevent patients from being harmed by cross-infection and mechanical failure.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1: Please refer to Figure 1 , Figure 2 and Figures 7-8 The present invention provides a technical solution: a sampling device for medical testing. The present invention makes corresponding improvements to the technical problems mentioned in the background art, including a sampling machine body 1, an anti-infection mechanism 2 provided inside the sampling machine body 1, and a double protection mechanism 3 provided inside the sampling machine body 1. The infection prevention mechanism 2 includes a disinfection unit 21, which is located inside the sampler body 1. The disinfection unit 21 can reduce the chance of cross-infection of pathogens. The infection prevention mechanism 2 also includes a leak prevention unit 22, which is located inside the sampler body 1. The leak prevention unit 22 can prevent the infection prevention mechanism 2 from constantly using a replacement sleeve with a broken or leaky hole. The dual protection mechanism 3 enables patients to actively avoid injury from a malfunctioning robotic arm.
[0023] As a further definition of the infection prevention mechanism 2 of the present invention, the disinfection unit 21 includes a rectangular frame 2101. The outer surface of the rectangular frame 2101 is fixedly connected to the inner wall of the sampler body 1. A spring return shaft 2104 is rotatably connected to the inner wall of the rectangular frame 2101. A first gear 2106 is fixedly connected to the outer surface of the spring return shaft 2104. Two toothed plates 2110 are slidably connected inside the rectangular frame 2101. A transmission shaft 2105 is fixedly connected to one side of each toothed plate 2110. A bullseye bearing 2116 is fixedly connected to one end of each transmission shaft 2105. Two replacement frames 2111 are provided inside the rectangular frame 2101. A replacement rubber sleeve 2107 is fixedly connected to the bottom surface of each replacement frame 2111. Two sets of first force springs 2114 are fixedly connected to the inner wall of the rectangular frame 2101. Each set of first force springs 2114 consists of three springs. Spring 2114 is in a compressed state, while another set of first force springs 2114 is in a normal state. Each set of first force springs 2114 has a push plate 2115 fixedly connected to its top. The upper surface of each push plate 2115 is in contact with the bottom surface of the replacement frame 2111. Each replacement frame 2111 has a circular locking hole 2117 and a rectangular hole 2118 on one side. One bullseye bearing 2116 and the drive shaft 2105 are located inside the rectangular hole 2118, and the other bullseye bearing 2116 and the drive shaft 2105 are located inside the circular locking hole 2117. By setting up a disinfection unit 21, the replacement frame 2111 and the replacement rubber sleeve 2107 in the disinfection unit 21 can protect the two clamps in the mechanical gripper 2103. After sampling a patient's oral cavity, the replacement frame 2111 and the replacement rubber sleeve 2107 are replaced to avoid cross-infection.
[0024] Please see Figure 7 The inner wall of the rectangular frame 2101 is rotatably connected to two turntables 2108. Each turntable 2108 has a second gear 2121 fixedly connected to one side. The two second gears 2121 are fixedly connected to an ultraviolet germicidal lamp 2109 on one side. By setting the ultraviolet germicidal lamp 2109, the replacement rubber sleeve 2107 can be sterilized.
[0025] Please see Figure 7 Two mounting blocks 2119 are fixedly connected to the inner bottom wall of the rectangular frame 2101. A drive motor 2122 is fixedly connected to the upper surface of each mounting block 2119. A third gear 2120 is fixedly connected to the output end of each drive motor 2122. The teeth of each third gear 2120 mesh with the teeth of the second gear 2121. By setting the drive motor 2122 and the third gear 2120, the drive motor 2122 can drive the third gear 2120 to rotate, providing power for its rotation.
[0026] Please see Figure 1 A test tube rack 2102 is fixedly connected to the upper surface of the sampler body 1. A mechanical gripper 2103 is provided above the sampler body 1. By providing the test tube rack 2102, the test tube rack 2102 can provide a storage position for the test tubes, while the mechanical gripper 2103 can hold the cotton swabs.
[0027] The specific implementation of this embodiment is as follows: When the device needs to be used, the person to be tested is positioned directly in front of the sampling machine body 1, with one hand placed above the sliding plate 301 and the other hand placed on the left side of the sampling machine body 1. Subsequently, the operation of the sampling machine body 1 will drive the clamping structure to extend into the replacement frame 2111 and replacement rubber sleeve 2107 behind the rectangular frame 2101. At this time, it should be understood that there are two replacement frames 2111 and two replacement rubber sleeves 2107 inside the rectangular frame 2101. The replacement rubber sleeve 2107 located at the rear is in a free and unlocked state, while the replacement frame 2111 located at the front is in a locked state. Therefore, the mechanical gripper 2103 will be placed on the replacement rubber sleeve 2107 located at the rear. Afterwards, when the mechanical gripper 2103 is in the clamping state, it can deform and clamp the replacement rubber sleeve 2107. Then, the mechanical gripper 2103 directly pulls out from inside the rectangular frame 2101 and grabs the cotton swab in the cotton swab compartment to take a sample from the patient's mouth. The mechanical gripper 2103 will move the sampled cotton swab to the test tube inside the test tube rack 2102, then insert the cotton swab head into the test tube, and break the cotton swab stick using the test tube inlet end to let the cotton swab part fall into the test tube, completing the sampling. Afterwards, the mechanical gripper 2103 will push the replacement frame 2111 and the replacement rubber sleeve 2107 back into place. Note that during the repositioning process, due to the mechanical gripper 2103's action on the replacement... As the frame 2111 and the replacement rubber pad are continuously pushed, they will continue to move downwards. Under the action of the pushing force, the bullseye bearing 2116 will retract into the interior of the rectangular frame 2101 under the action of the ramp at the edge of the rectangular hole 2118, and drive one toothed plate 2110 to move. The meshing function of the toothed plate 2110 and the first gear 2106 can drive the other toothed plate 2110 to move, thereby pulling the other bullseye bearing 2116 out of the circular locking hole 2117 inside the front replacement frame 2111. At this time, the front replacement frame 2111 will move upwards under the action of the elastic force of the first force spring 2114 until the mechanical gripper 2103 continues to push the rear replacement frame 2111 downwards to the circular locking hole. When hole 2117 is positioned opposite to the rear bullseye bearing 2116, the bullseye bearing 2116 will reset under the action of spring return shaft 2104, causing the rear bullseye bearing 2116 to engage with the rear circular locking hole 2117. Meanwhile, the front replacement frame 2111 will move to a position symmetrical to the rectangular hole 2118 and bullseye bearing 2116 under the action of the first force spring 2114. Therefore, the front bullseye bearing 2116 cannot engage with the circular locking hole 2117 to limit and fix the front replacement frame 2111. Then, the mechanical gripper 2103 can clamp the front replacement frame 2111 for the next inspection. This ensures that the same replacement frame 2111 will not be inspected twice consecutively.Subsequently, the ultraviolet germicidal lamp 2109 will sterilize the replacement rubber sleeve 2107 and the replacement frame 2111. It's important to understand that both the replacement rubber sleeve 2107 and the replacement frame 2111 are made of transparent material, allowing for effective sterilization by the ultraviolet germicidal lamp 2109.
[0028] Example 2: Please refer to Figure 1 , Figure 2 and Figures 4-6 The present invention provides a technical solution: a sampling device for medical testing, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.
[0029] As a further definition of the infection prevention mechanism 2 of the present invention, the leak prevention unit 22 includes a rotating plate 2201. An air pump 2206 is fixedly connected to one side of the rotating plate 2201. The output end of the air pump 2206 is fixedly connected to a suction pipe 2204. The output end of the air pump 2206 is fixedly connected to a bidirectional output pipe 2202. The outer surface of the bidirectional output pipe 2202 is fixedly connected to the inner wall of the rotating plate 2201. Two solenoid valves 2203 are fixedly connected to the outer surface of the bidirectional output pipe 2202. Two trigger buttons 2208 are fixedly connected to the inner wall of the bidirectional output pipe 2202. A circular plate 2207 is provided on one side of each trigger button 2208. The outer surface of each circular plate 2207 is slidably connected to... Inside the bidirectional output tube 2202, two spare frames 2113 are provided inside the rectangular frame 2101. The outer surface of each spare frame 2113 is in contact with the outer surface of the rectangular frame 2101. A spare rubber sleeve 2112 is fixedly connected to the bottom surface of each spare frame 2113. By setting a leak-proof unit 22, the leak-proof unit 22 can perform a seal test on the replacement rubber sleeve 2107 and the replacement frame 2111. If the replacement rubber sleeve 2107 has a hole, the spare rubber sleeve 2112 and the spare replacement frame 2111 will be automatically replaced. This avoids the mechanical gripper 2103 from using the damaged replacement rubber sleeve 2107 continuously, which could cause pathogens to adhere to the surface of the mechanical gripper 2103.
[0030] Please see Figure 6 A stepper motor 2210 is fixedly connected to the inner wall of the sampler body 1. A long shaft 2205 is fixedly connected to the output end of the stepper motor 2210. The outer surface of the long shaft 2205 is fixedly connected to the inner wall of the rotating plate 2201. Two fixed plates 2209 are fixedly connected to the upper surface of the rectangular frame 2101. The outer surface of the long shaft 2205 is rotatably connected to the inner wall of the two fixed plates 2209. By setting the stepper motor 2210, the operation of the stepper motor 2210 can drive the long shaft 2205 to rotate, providing power for the rotation of the rotating plate 2201.
[0031] The specific implementation of this embodiment is as follows: When it is necessary to check the sealing performance of the replacement rubber sleeve 2107 and observe whether it is damaged, it is only necessary to pre-set the control logic through the controller. When damage detection is required, each time the mechanical gripper 2103 checks and replaces the replacement rubber sleeve 2107, the stepper motor 2210 will run. The operation of the stepper motor 2210 can drive the long shaft 2205 and the rotating plate 2201 to rotate until the rotating plate 2201 rotates 90 degrees and covers the upper surface of the rectangular frame 2101. The surface of the rotating plate 2201 is covered with a layer of rubber. Under the action of the rubber, it can be ensured that the gas generated by the air pump 2206 will not leak when it is running. Then, the air pump 2206 will draw outside air into the air pump 2206 through the air extraction pipe 2204, and through... The bidirectional output pipe 2202 outputs to one of the replacement rubber sleeves 2107. It is important to understand that when testing a particular replacement rubber sleeve 2107, the corresponding solenoid valve 2203 needs to be opened while the other side is closed. The air pump 2206 generates a relatively low gas flow rate. If the replacement rubber sleeve 2107 is not damaged, it can still move the circular plate 2207 and touch the trigger button 2208, even with a large amount of gas accumulating inside the bidirectional air outlet pipe and the replacement rubber sleeve 2107. This indicates that the replacement rubber sleeve 2107 on this side is well sealed. Otherwise, it indicates damage. At this time, the mechanical gripper 2103 can be opened to throw off the replacement rubber sleeve 2107 covering its surface. Then, the spare rubber sleeve 2112 can be clamped and used.
[0032] Example 3: Please refer to Figure 1 and Figure 3 The present invention provides a technical solution: a sampling device for medical testing, and the present invention makes corresponding improvements to the technical problems mentioned in the background art.
[0033] As a further definition of the dual protection mechanism 3 of the present invention, the dual protection mechanism 3 includes a sliding plate 301, the bottom surface of a mechanical gripper 2103 is fixedly connected to the upper surface of the sliding plate 301, a second force spring 307 is fixedly connected to the inner bottom wall of the sliding plate 301, a pressing shaft 304 is fixedly connected to the top end of the second force spring 307, two grooves 302 are formed on the outer surface of the pressing shaft 304, an emergency stop button 306 is fixedly connected to the inner bottom wall of the sliding plate 301, the emergency stop button 306 is disposed in the inner cavity of the second force spring 307, and two circular rings 309 are fixedly connected to the inner wall of the sliding plate 301, with one side of each circular ring 309 fixedly connected to... There is a third force spring 310, and one end of each third force spring 310 is fixedly connected to a sensing block 311. One end of each sensing block 311 is fixedly connected to a fixed shaft 308. One end of each fixed shaft 308 passes through the sampler body 1 and extends into the interior of the sampler body 1. The outer surface of each sensing block 311 is in contact with the outer surface of the pressing shaft 304. By setting up a double protection mechanism 3, the patient can be effectively protected and mechanical injury can be avoided. By setting up a disinfection unit 21, a leak-proof unit 22 and a double protection mechanism 3, the problem of patients being injured due to cross-infection and mechanical failure can be effectively avoided.
[0034] Please see Figure 3 A T-shaped groove 305 is provided on one side of the sampler body 1. A T-shaped slider 303 is slidably connected inside the T-shaped groove 305. The upper surface of the T-shaped slider 303 is fixedly connected to the bottom surface of the sliding plate 301. By providing the T-shaped slider 303, the T-shaped slider 303 can slide inside the T-shaped groove 305, providing a limit for the sliding plate 301.
[0035] The specific implementation of this embodiment is as follows: When the mechanical gripper 2103 malfunctions, the subject's hand is on the sliding plate 301. Under the action of physiological reaction, the subject will quickly press the pressing shaft 304, and both hands will apply a pushing force to the sliding plate 301 and the sampling machine body 1. When the pressing shaft 304 is pressed down, the groove 302 on the surface of the pressing shaft 304 will move to one side of the sensing block 311. Under the action of the third force spring 310, the sensing block 311 can spring into the interior of the groove 302. At this time, the sensing block 311... The fixed shaft 308, which is fixed at one end, will detach from the inside of the sampler body 1. Therefore, the sliding plate 301 is not subject to any limit at this time. When the pressing shaft 304 moves downward, it will trigger the emergency stop button 306. The emergency stop button 306 will also control the mechanical gripper 2103 to stop. Even if the emergency stop button 306 is out of control, the tester will still apply a pushing force to the sliding plate 301 under the action of physiological reaction. Therefore, the mechanical gripper 2103 can be pushed physically away from the mouth of the tester, which plays a dual protection role.
[0036] A method for using a medical testing sampling device includes the following steps: S1: When the equipment needs to be used, the person to be tested is positioned directly in front of the sampling machine body 1, with one hand placed above the sliding plate 301 and the other hand placed on the left side of the sampling machine body 1. The sampling machine body 1 then operates, driving the clamping structure to extend into the replacement frame 2111 and replacement rubber sleeve 2107 behind the rectangular frame 2101. It should be understood that there are two replacement frames 2111 and two replacement rubber sleeves 2107 inside the rectangular frame 2101. The replacement rubber sleeve 2107 at the rear is in a free and unlocked state, while the replacement frame 2111 at the front is in a locked state. Therefore, the mechanical gripper 2103 will fit onto the replacement rubber sleeve 2107 at the rear. Subsequently, the mechanical gripper 2103 operates in a clamping state. When in this state, the mechanical gripper 2103 can deform and clamp the replacement rubber sleeve 2107. Then, the mechanical gripper 2103 directly withdraws from inside the rectangular frame 2101 and grabs a cotton swab from the rear cotton swab compartment for sampling the patient's oral cavity. The mechanical gripper 2103 then moves the sampled cotton swab to a test tube inside the test tube rack 2102. The cotton swab tip is then inserted into the test tube, and the swab stick is broken off using the test tube inlet to allow the swab portion to fall into the test tube, completing the sampling. Afterward, the mechanical gripper 2103 pushes the replacement frame 2111 and the replacement rubber sleeve 2107 back into place. Note that during the repositioning process, the mechanical gripper 2103 continuously applies a pushing force to the replacement frame 2111 and the replacement rubber sleeve. 1. The replacement rubber pad will continue to move downwards. Under the action of the thrust, the bullseye bearing 2116 will retract into the interior of the rectangular frame 2101 under the action of the ramp at the edge of the rectangular hole 2118, and drive one toothed plate 2110 to move. The meshing function of the toothed plate 2110 and the first gear 2106 can drive the other toothed plate 2110 to move, thereby pulling the other bullseye bearing 2116 out of the circular locking hole 2117 inside the front replacement frame 2111. At this time, the front replacement frame 2111 will move upwards under the action of the elastic force of the first force spring 2114 until the mechanical gripper 2103 continues to push the rear replacement frame 2111 downwards until the circular locking hole 2117 is in the position opposite to the rear bullseye bearing 2116. At this time, the bullseye bearing 2116... 6 will reset under the action of spring return shaft 2104, causing the rear bullseye bearing 2116 to engage with the rear circular locking hole 2117. Meanwhile, the front replacement frame 2111 will move to a position symmetrical to the rectangular hole 2118 and bullseye bearing 2116 under the action of the first force spring 2114. Therefore, the front bullseye bearing 2116 cannot engage with the circular locking hole 2117 to limit and fix the front replacement frame 2111. Then, the mechanical gripper 2103 can clamp the front replacement frame 2111 for the next inspection. This ensures that the same replacement frame 2111 will not be inspected twice consecutively. Finally, the ultraviolet germicidal lamp 2109 will sterilize the replacement rubber sleeve 2107 and the replacement frame 2111.It's important to understand that both the replacement rubber sleeve 2107 and the replacement frame 2111 are made of transparent material, allowing for effective sterilization by the ultraviolet germicidal lamp 2109. S2: When it is necessary to check the sealing performance of the replacement rubber sleeve 2107 and observe whether it is damaged, the control logic only needs to be set in advance through the controller. When damage detection is required, the stepper motor 2210 will run every time the mechanical gripper 2103 checks and replaces the replacement rubber sleeve 2107. The stepper motor 2210 can drive the long shaft 2205 and the rotating plate 2201 to rotate until the rotating plate 2201 rotates 90 degrees and covers the upper surface of the rectangular frame 2101. The surface of the rotating plate 2201 is covered with a layer of rubber. Under the action of the rubber, the gas generated by the air pump 2206 will not leak. Then the air pump 2206 will draw outside air into the air pump 2206 through the air extraction pipe 2204 and output air through the bidirectional output pipe. 2202 outputs to one of the replacement rubber sleeves 2107. At this point, it is important to understand that when testing a particular replacement rubber sleeve 2107, the solenoid valve 2203 on the corresponding side needs to be opened while the other side is closed. Also, the air pump 2206 generates a relatively low gas flow rate. If the replacement rubber sleeve 2107 is not damaged, it can still push the circular plate 2207 to move and touch the trigger button 2208, even with a large amount of gas accumulating inside the bidirectional air outlet pipe and the replacement rubber sleeve 2107. This indicates that the replacement rubber sleeve 2107 on this side is well sealed. Otherwise, it indicates damage. At this point, the mechanical gripper 2103 can be opened to throw off the replacement rubber sleeve 2107 covering its surface. Then, the spare rubber sleeve 2112 can be clamped and used. S3: When the mechanical gripper 2103 malfunctions, the subject's hand is on the sliding plate 301. Under physiological reflex, the subject will quickly press the pressing shaft 304, and both hands will apply a pushing force to the sliding plate 301 and the sampling machine body 1. After the pressing shaft 304 is pressed down, the groove 302 on the surface of the pressing shaft 304 will move to one side of the sensing block 311. Under the action of the third force spring 310, the sensing block 311 can spring into the interior of the groove 302. At this time, one end of the sensing block 311 is fixed. The fixed shaft 308 will detach from the inside of the sampler body 1. Therefore, the sliding plate 301 is not subject to any limit at this time. When the pressing shaft 304 moves downward, it will trigger the emergency stop button 306. The emergency stop button 306 will also control the mechanical gripper 2103 to stop. Even if the emergency stop button 306 is out of control, the tester will still apply a pushing force to the sliding plate 301 under the action of physiological reaction. Therefore, the mechanical gripper 2103 can be pushed physically away from the mouth of the tester, which plays a dual protection role.

10. A method of using a medical testing sampling device according to any one of claims 1-9, characterized in that: Specifically, the following steps are included: S1: When the equipment needs to be used, the person to be tested is located directly in front of the sampler body (1), with one hand placed above the sliding plate (301) and the other hand placed on the left side of the sampler body (1). Then, the sampler body (1) will run and drive the gripping structure to extend into the replacement frame (2111) and replacement rubber sleeve (2107) behind the rectangular frame (2101). At this time, it should be understood that there are two replacement frames (2111) and two replacement rubber sleeves (2107) inside the rectangular frame (2101). The replacement rubber sleeve (2107) located at the rear is in a free and unlocked state, while the replacement frame (2111) located at the front is in a locked state. Therefore, the mechanical gripper (2103) The swab will be placed on the replacement rubber sleeve (2107) located at the rear. Then, when the mechanical gripper (2103) is in the clamping state, it can deform the replacement rubber sleeve (2107) and clamp it. Then, the mechanical gripper (2103) is directly pulled out from the inside of the rectangular frame (2101) and grabs the cotton swab in the rear cotton swab chamber to perform sampling on the patient's oral cavity. The mechanical gripper (2103) will move the sampled cotton swab to the test tube inside the test tube rack (2102), and then insert the cotton swab head into the test tube. By using the test tube inlet end, the cotton swab stick can be broken off so that the cotton swab part falls into the test tube, completing the sampling work. Then, the mechanical gripper (2103) will push the replacement rubber sleeve (2107) to the rear. The frame (2111) and the replacement rubber sleeve (2107) are returned to their original positions. Note that during the return process, the mechanical gripper (2103) continuously applies a pushing force to the replacement frame (2111) and the replacement rubber pad, causing them to continuously move downwards. Under the action of this pushing force, the bullseye bearing (2116) retracts into the interior of the rectangular frame (2101) under the action of the ramp at the edge of the rectangular hole (2118), and drives one toothed plate (2110) to move. The meshing function of the toothed plate (2110) and the first gear (2106) can drive another toothed plate (2110) to move, thereby pushing the other bullseye bearing (2116) out of the circular locking hole inside the front replacement frame (2111). When the replacement frame (2117) is pulled out, the front replacement frame (2111) will move upward under the force of the first force spring (2114) until the mechanical gripper (2103) continues to push the rear replacement frame (2111) downward to the position where the circular locking hole (2117) is opposite to the rear bullseye bearing (2116). At this time, the bullseye bearing (2116) will be reset under the action of the spring return shaft (2104), so that the rear bullseye bearing (2116) is locked into the rear circular locking hole (2117). The front replacement frame (2111) will move to the position where the rectangular hole (2118) is symmetrical to the bullseye bearing (2116) under the action of the first force spring (2114). Therefore,The bullseye bearing (2116) at the front cannot engage with the circular locking hole (2117) to limit and fix the front replacement frame (2111). Then, the mechanical gripper (2103) can clamp the front replacement frame (2111) for the next inspection. This ensures that the same replacement frame (2111) will not be inspected twice consecutively. Subsequently, the ultraviolet germicidal lamp (2109) will sterilize the replacement rubber sleeve (2107) and the replacement frame (2111). It should be noted that both the replacement rubber sleeve (2107) and the replacement frame (2111) are made of transparent material, allowing for effective sterilization by the ultraviolet germicidal lamp (2109). S2: When it is necessary to check the sealing performance of the replacement rubber sleeve (2107) and observe whether it is damaged, it is only necessary to set the control logic in advance through the controller. When damage detection is required, the stepper motor (2210) will run after the mechanical gripper (2103) checks and replaces the replacement rubber sleeve (2107). The stepper motor (2210) can drive the long shaft (2205) and the rotating plate (2201) to rotate until the rotating plate (2201) rotates 90 degrees and covers the upper surface of the rectangular frame (2101). The surface of the rotating plate (2201) is covered with a layer of rubber. Under the action of the rubber, it can ensure that the gas generated by the air pump (2206) will not leak when it runs. Then the air pump (2206) will draw outside air into the air pump (2206) through the air extraction pipe (2204) and output bidirectionally. The tube (2202) outputs to one of the replacement rubber sleeves (2107). At this time, it is necessary to understand which side of the replacement rubber sleeve (2107) needs to be tested. The corresponding side's solenoid valve (2203) needs to be opened, while the other side is closed. The gas flow rate generated by the air pump (2206) is relatively small. If the replacement rubber sleeve (2107) is not damaged, it can still push the circular plate (2207) to move and touch the trigger button (2208) under the premise that the gas inside the bidirectional air outlet tube and the replacement rubber sleeve (2107) is large. This means that the replacement rubber sleeve (2107) on this side is well sealed. Otherwise, it means that it is damaged. At this time, the mechanical gripper (2103) can be opened and the replacement rubber sleeve (2107) covering its surface can be thrown off. Then the spare rubber sleeve (2112) can be clamped and used. S3: When the mechanical gripper (2103) malfunctions, the subject's hand is on the sliding plate (301). Under the action of physiological reaction, the subject will quickly press the pressing shaft (304), and both hands will apply a pushing force to the sliding plate (301) and the sampler body (1). When the pressing shaft (304) is pressed down, the groove (302) opened on the surface of the pressing shaft (304) will move to one side of the sensing block (311). Under the action of the third force spring (310), the sensing block (311) can spring into the inside of the groove (302). At this time, the sensing block (311) The fixed shaft (308) fixed at one end will detach from the inside of the sampler body (1). Therefore, the sliding plate (301) is not subject to any limit at this time. When the pressing shaft (304) moves downward, it will trigger the emergency stop button (306). The emergency stop button (306) will also control the mechanical gripper (2103) to stop. Even if the emergency stop button (306) is out of control, the tester will apply a pushing force to the sliding plate (301) under the action of physiological reaction. Therefore, the mechanical gripper (2103) can be pushed physically away from the mouth of the tester, playing a dual protection role.
