[0022] S7: Use the inspection instrument pipette to take samples from the sampling tube and carry out subsequent testing. After the sampling is completed, push the cover plate down to reset it. The cover plate drives the tube cover to be re-covered on the sampling tube to prevent contamination.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The sample collection and inspection device and method for the laboratory of the present invention are provided with a cover-opening mechanism. When taking a sample from a sampling test tube for inspection, the cover-opening plate above the sample is pushed to flip upward around the pin axis, and the cover-opening plate drives the snap ring to flip upward. The clamping action of the clamp block and the snap ring is used to apply an upward pulling force to the tube cover of the sampling test tube. At this time, the sampling test tube is kept stationary with the box body due to the friction of the rubber ring, so that the cover-opening plate drives the sampling test tube to separate from the tube cover, thereby achieving the effect of quickly opening the tube cover of the auxiliary sampling test tube, reducing the trouble of the inspector frequently opening the tube cover for sampling.

[0025] 2. The sample collection and inspection device and method for the laboratory of the present invention, by setting an anti-slip mechanism, when the sampling test tube is placed in the box and prepared for inspection, the slide plate is inserted into the slide grooves on the left and right sides of the box, and the slide plate is pushed to slide down in the slide groove, and the clamping block is stuck in the clamping groove and slides until the top bending part of the limit plate just presses on the multiple cover plates, and then the slide plate is positioned by connecting the screw hole through the slide plate, and the multiple cover plates are positioned by using the limit plate, which can effectively prevent the tube cover of the sampling test tube from being accidentally opened due to collision during the inspection process, and cooperate with the rubber ring that clamps the sampling test tube and the clamping block that clamps the tube cover to ensure that the sampling test tube will not shake or fall off inside the box, thereby increasing the safety of the sampling test tube in inspection.

[0026] 3. The sample collection and inspection device and method for the laboratory of the present invention provide a heat preservation chamber. After the sampling test tube is inserted into the heat preservation chamber, warm water or ice water is added into the heat preservation chamber through the water inlet. The tube wall of the sampling test tube is directly immersed in the water, which provides an optimal storage environment for the sample and prevents the collected sample from being affected by the ambient temperature. At the same time, the temperature sensor detects the real-time temperature in the heat preservation chamber and transmits the temperature data to the microprocessor. The microprocessor transmits the data to the display screen for display, which is convenient for the user to observe the temperature change.

[0027] 4. The sample collection and inspection device and method for the laboratory of the present invention are provided with a start button and a timer. After the first collected sample tube is placed in the box, the start button is pressed to record the time when the sampling tube is first placed.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figures 1 to 6As shown, the sample collection and inspection device for the laboratory in this embodiment includes a box body 1, and a socket 2 is opened on the upper surface of the box body 1. The number of the sockets 2 is several, and multiple sampling test tubes 4 are placed. The sockets 2 on both sides of the fixing seat 6 are staggered front and back to facilitate the installation of the cover opening mechanism 7. The inner wall of the socket 2 is provided with a rubber ring 3, and the rubber ring 3 is fixed to the inner wall of the socket 2. After the sampling test tube 4 is inserted into the socket 2, the tube wall of the sampling test tube 4 squeezes the rubber ring 3 for compression and deformation, and the movement of the sampling test tube 4 is limited by the rebound force of the rubber ring 3. The rubber ring 3 is movably inserted with the sampling test tube 4. Tube 4, the sampling test tube 4 is plugged into the tube cover, and the sampling test tube 4 can be separated from the tube cover by pulling the tube cover upward. An insulation chamber 5 is provided inside the box 1 for heat preservation and storage of the sampling test tube 4. A fixing seat 6 is connected to the middle of the upper surface of the box 1. Both sides of the fixing seat 6 are provided with opening mechanisms 7 for assisting the rapid separation of the sampling test tube 4 from the tube cover. The number of opening mechanisms 7 corresponds to the number of the jacks 2. Both sides of the left and right walls of the box 1 are provided with slide grooves 8. The slide grooves 8 are provided with anti-slip mechanisms 9 for maintaining the stability of the sampling test tube 4 in the box 1;

[0039] The opening mechanism 7 comprises an opening cover plate 71, a pin shaft 72 is provided on one side of the opening cover plate 71 close to the fixing seat 6, a torsion spring 73 is sleeved on the outer side of the pin shaft 72, and the torsion spring 73 is in a normal stretched state when the opening cover plate 71 is in a horizontal state. When the user pushes the opening cover plate 71 to flip upward, the torsion spring 73 generates a torque force, which has the tendency to pull the opening cover plate 71 to rotate and reset. A through hole 74 is provided in the middle of the opening cover plate 71 for the sampling test tube 4 to pass through the opening cover plate 71 and insert into the box body 1. A snap ring 75 is connected to the bottom of the opening cover plate 71, and a slot 76 is provided on the opening cover plate 71 outside the through hole 74. The slot 76 is annular, and an insert ring 77 is provided inside the slot 76. A knob 78 is connected to the top of 77, and the knob 78 is used to facilitate manual rotation of the plug ring 77 so that the plug ring 77 can be rotated and raised in the slot 76. The outer wall of the plug ring 77 and the inner wall of the slot 76 are both provided with threads 79. A through slot 710 is provided between the slot 76 and the through hole 74. A clamping block 711 is provided inside the through slot 710. A rubber block 712 is connected to the side of the clamping block 711 away from the plug ring 77. The rubber block 712 is used to increase the friction between the clamping block 711 and the side wall of the tube cover so as to firmly clamp the tube cover. A fixing block 713 is vertically connected to the upper surface of the cover plate 71 above the pin shaft 72, and a protrusion 714 is connected to the front and rear side walls of the fixing block 713.

[0040] Specifically, the cover plate 71 is rotatably connected to the fixing seat 6 via the pin shaft 72, and the sampling test tube 4 passes through the through hole 74 and sequentially passes through the cover plate 71 and the clamping ring 75, and the clamping ring 75 is clamped at the bottom of the tube cover of the sampling test tube 4. The clamping ring 75 is annular, and the inner diameter of the bottom of the clamping ring 75 is larger than the outer diameter of the sampling test tube 4 and smaller than the outer diameter of the tube cover, so that the sampling test tube 4 passes through the through hole 74 and the tube cover is placed on the clamping ring 75. When the manual push rod cover plate 71 rotates upward around the pin shaft 72, the cover plate 71 The snap ring 75 is driven to flip upward, and the snap ring 75 applies an upward pulling force to the tube cover. At this time, the sampling test tube 4 is kept stationary with the box body 1 due to the friction force of the rubber ring 3, so that the cover opening plate 71 drives the sampling test tube 4 to separate from the tube cover. The rubber ring 3 is made of softer rubber to increase the friction between the sampling test tube 4 and the rubber ring 3, so that the static friction between the sampling test tube 4 and the rubber ring 3 is greater than the static friction between the sampling test tube 4 and the tube cover, ensuring that the sampling test tube 4 is separated from the tube cover smoothly.

[0041] Furthermore, the insert ring 77 is in the shape of a circular ring with a right-angled trapezoidal longitudinal section. The inner wall of the insert ring 77 is inclined. The insert ring 77 is wide at the top and narrow at the bottom. The insert ring 77 is connected to the thread 79 of the slot 76 via the thread 79. The inner wall of the insert ring 77 is in contact with the clamping block 711. The insert ring 77 is rotated by turning the knob 78, so that the insert ring 77 rotates and descends in the slot 76 via the thread 79, and the inner wall of the insert ring 77 descends, pushing multiple clamping blocks 711 to move in the through groove 710.

[0042] Furthermore, the slot 76 is connected to the through hole 74 via the through groove 710, and the clamping block 711 is slidably connected to the inner wall of the through groove 710. There are several clamping blocks 711, which are arranged equidistantly in the circumferential direction in the through groove 710. The clamping block 711 contacts the outer wall of the tube cover of the sampling test tube 4 via the rubber block 712. When the insert ring 77 descends in the slot 76 to push the clamping block 711 to move in the through groove 710, the clamping block 711 gradually extends into the through hole 74 and clamps the side wall of the tube cover of the sampling test tube 4 via the rubber block 712.

[0043] Furthermore, a groove 61 is provided on the upper surface of the fixing seat 6, and the inner walls on the front and rear sides of the groove 61 are connected to the limiting block 62. When the fixing block 713 rotates around the pin shaft 72, it is movably connected with the groove 61. The limiting block 62 is truncated cone-shaped, and the fixing block 713 is clamped with the limiting block 62 via the protrusion 714. When a sample is taken, the opening cover plate 71 above the sample is pushed to flip upward around the pin shaft 72. At the same time, the opening cover plate 71 drives the fixing block 713 to be inserted into the groove 61, and the fixing block 713 drives the protrusion 714 to squeeze the limiting block 62, so that the protrusion 714 moves from one side of the limiting block 62 to the other side. At this time, the limiting block 62 limits the protrusion 714 from resetting to fix the upward flipping position of the opening cover plate 71.

[0044] Furthermore, the anti-slip mechanism 9 includes a limit plate 91, and a slide plate 92 is connected to the bottom of the limit plate 91 near the front and rear edges. The front and rear side walls of the slide plate 92 are provided with a slot 93, and a screw 94 is provided through the middle of the slide plate 92. The limit plate 91 is integrally connected with the slide plate 92. The top of the limit plate 91 is bent at a right angle to form a rectangular plate with an L-shaped longitudinal section. The limit plate 91 and the slide plate 92 are both movably connected to the slide groove 8. By inserting the slide plate 92 into the slide grooves 8 on the left and right sides of the box body 1, the box body 1 can be pushed. The movable slide plate 92 slides down in the slide groove 8 until the top bend of the limit plate 91 just presses on the multiple cover plates 71, and the multiple cover plates 71 are positioned, which can effectively prevent the tube cover of the sampling test tube 4 from being accidentally opened due to collision during the inspection process. The limit plate 91, the slide plate 92 and the box body 1 are detachably installed, and are inserted into the slide groove 8 when sending for inspection. When storing the sampling test tube 4, the limit plate 91 and the slide plate 92 are removed and placed aside, and are fully inserted into the slide groove 8 when idle.

[0045] Furthermore, blocks 81 are connected to the inner walls on both the front and rear sides of the slide groove 8, and a screw hole 82 is opened on the box body 1 on one side of the slide groove 8. The block 81 is plugged into the movable groove of the card slot 93. The card block 81 and the card slot 93 are engaged to ensure that the slide plate 92 can be stably lifted and lowered in the slide groove 8 and will not fall off the slide groove 8. The screw 94 passes through the slide plate 92 and is connected to the thread 79 of the screw hole 82. The screw 94 is passed through the slide plate 92 and is connected to the screw hole 82 to position the slider.

[0046] Furthermore, a water inlet 10 is provided at the edge of the upper surface of the box body 1 near the rear side, and a water outlet 11 is provided on the rear side wall of the box body 1 for discharging water in the insulation chamber 5. The water inlet 10 and the water outlet 11 are both connected with a sealing cover 12 by threads 79. The water inlet 10 and the water outlet 11 are both connected to the insulation chamber 5. Warm water or ice water is stored inside the insulation chamber 5. Warm water or ice water is added to the insulation chamber 5 through the water inlet 10, and the wall of the sampling test tube 4 is directly immersed in water, which provides an optimal storage environment for the sample and prevents the collected sample from being affected by the ambient temperature.

[0047] Furthermore, a display screen 13 is installed on the front side wall of the box 1, and the temperature data of the water in the insulation chamber 5 and the timing time of the timer 18 are displayed on the display screen 13. A start button 14 is installed on the front side wall of the box 1 on one side of the display screen 13. A microprocessor 15 is installed inside the box 1 on the front side of the insulation chamber 5. The microprocessor 15 is electrically connected to the battery 16. The microprocessor 15 is electrically connected to the timer 18. After the first collected sample tube is placed in the box 1, the start button is pressed to record the time when the sampling tube 4 is first placed, so that medical staff can observe the storage time of the sampling tube 4 for timely inspection. A temperature sensor 17 is installed inside the insulation chamber 5. The temperature sensor 17 is electrically connected to the microprocessor through a circuit. The temperature sensor 17 detects the real-time temperature in the insulation chamber 5 and transmits the temperature data to the microprocessor 15. The microprocessor 15 transmits the data to the display screen 13 for display, so that the user can observe the temperature changes.
