[0015] A use method of the sample collection and delivery device for a clinical laboratory, comprising the following steps:

[0016] S1: the sampling test tube with the sample is inserted into the insertion hole through the through hole, the opening plate and the snap ring, the sampling test tube is compressed and deformed by pressing the rubber ring, and the bottom of the sampling test tube is inserted into the heat preservation cavity;

[0017] S2: Insert the insert ring into the slot and rotate the insert ring by turning the knob, so that the insert ring rotates and descends in the slot through the thread. The descending of the insert ring pushes multiple clamping blocks to move in the through groove until the multiple clamping blocks clamp the side wall of the tube cap of the sampling tube through the rubber block.

[0018] S3: Press the start button to record the time when the sampling tube is first placed in the sample tube. The start button inputs a command to the microprocessor, and the microprocessor controls the timer to start timing.

[0019] S4: Based on the preservation characteristics of the sample, add warm water or ice water into the insulation chamber through the water inlet to provide the optimal preservation environment for the sample.

[0022] S7: Use a pipette to take a sample from the sampling tube for subsequent testing. After sampling, push the cap plate downwards to reset it. The cap plate will then re-cover the sampling tube to prevent contamination.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The laboratory sample collection and delivery device and method of the present invention, by setting up a cap opening mechanism, when taking a sample from a sampling tube for testing, pushes the cap opening plate above the sample to rotate upward around the pin axis. The cap opening plate drives the retaining ring to rotate upward, and the clamping block and retaining ring engage to apply an upward pulling force to the cap of the sampling tube. At this time, the sampling tube remains stationary with respect to the box body due to the friction of the rubber ring, so that the cap opening plate drives the sampling tube to separate from the cap, achieving the effect of quickly opening the cap of the auxiliary sampling tube and reducing the trouble of frequent opening of the cap for sampling by laboratory personnel.

[0025] 2. The laboratory sample collection and delivery device and method of the present invention, by setting an anti-detachment mechanism, when the sampling tube is placed in the box for delivery, inserts the sliding plate into the sliding grooves on the left and right sides of the box, pushes the sliding plate down in the sliding groove, and the locking block slides in the locking groove until the top bend of the limiting plate just presses on multiple opening plates. Then, the sliding plate is positioned by connecting the sliding plate with the screw hole through the screw. The positioning plate is used to position multiple opening plates, which can effectively prevent the tube cap of the sampling tube from being accidentally opened by collision during delivery. With the rubber ring holding the sampling tube and the clamping block holding the tube cap, it can be ensured that the sampling tube will not shake or fall off inside the box, increasing the safety of the sampling tube delivery.

[0026] 3. The laboratory sample collection and delivery device and method of the present invention, by setting up an insulated cavity, after the sampling tube is inserted into the insulated cavity, warm water or ice water is added into the insulated cavity through the water inlet, and the tube wall of the sampling tube is directly immersed in the water, providing an optimal preservation environment for the sample, so that the collected sample is not affected by the ambient temperature. At the same time, the temperature sensor detects the real-time temperature in the insulated cavity and transmits the temperature data to the microprocessor. The microprocessor transmits the data to the display screen for display, so that the user can easily observe the temperature changes.

[0027] 4. The laboratory sample collection and delivery device and method of the present invention, by setting a start button and a timer, after the first collected sample tube is placed into the box, the start button is pressed to record the time when the sample tube is first placed in. The start button inputs an instruction to the microprocessor, and the microprocessor controls the timer to start timing, so that medical staff can observe the storage time of the sample tube for timely delivery.

For example, "connection" 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 an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] like Figures 1 to 6As shown, the sample collection and delivery device for the laboratory in this embodiment includes a housing 1. The upper surface of the housing 1 has several insertion holes 2 for holding multiple sampling tubes 4. The insertion holes 2 on both sides of the fixing base 6 are staggered to facilitate the installation of the opening mechanism 7. A rubber ring 3 is provided on the inner wall of the insertion hole 2 and is fixed to the inner wall of the insertion hole 2. After the sampling tube 4 is inserted into the insertion hole 2, the tube wall of the sampling tube 4 compresses and deforms the rubber ring 3, using the elastic force of the rubber ring 3 to restrict the movement of the sampling tube 4. A sampling tube is movably inserted into the rubber ring 3. The sampling tube 4 is inserted into the tube cap. The sampling tube 4 can be separated from the tube cap by pulling the tube cap upward. The box body 1 has an insulation cavity 5 for storing the sampling tube 4 in an insulated manner. A fixed seat 6 is connected to the middle of the upper surface of the box body 1. The left and right sides of the fixed seat 6 are equipped with a cap opening mechanism 7 to assist the sampling tube 4 in quickly separating from the tube cap. The number of cap opening mechanisms 7 corresponds one-to-one with the insertion hole 2. The left and right side walls of the box body 1 are provided with sliding grooves 8. The sliding grooves 8 are equipped with anti-detachment mechanisms 9 to maintain the stability of the sampling tube 4 in the box body 1.

[0039] The opening mechanism 7 includes an opening plate 71. A pin 72 is inserted through the opening plate 71 near the fixed base 6. A torsion spring 73 is sleeved on the outside of the pin 72. When the opening plate 71 is in a horizontal state, the torsion spring 73 is in a normally stretched state. When the user pushes the opening plate 71 to flip it upward, the torsion spring 73 generates a torque force, which tends to pull the opening plate 71 to rotate and reset. A through hole 74 is opened through the middle of the opening plate 71 for the sampling tube 4 to pass through the opening plate 71 and be inserted into the box 1. A retaining ring 75 is connected to the bottom of the opening plate 71. A slot 76 is opened on the opening plate 71 outside the through hole 74. The slot 76 is annular and a retaining ring 77 is provided inside the slot 76. A knob 78 is connected to the top of the ring 77. The knob 78 is used to facilitate manual rotation of the ring 77, so that the ring 77 can rotate and rise within the slot 76. The outer wall of the ring 77 and the inner wall of the slot 76 are both provided with threads 79. A through groove 710 is provided between the slot 76 and the through hole 74. A clamping block 711 is provided inside the through groove 710. A rubber block 712 is connected to the side of the clamping block 711 away from the ring 77. The rubber block 712 is used to increase the friction between the clamping block 711 and the side wall of the tube cap, so as to securely clamp the tube cap. A fixing block 713 is vertically connected to the upper surface of the cover plate 71 above the pin 72. Both the front and rear side walls of the fixing block 713 are connected with protrusions 714.

[0040] Specifically, the cover plate 71 is rotatably connected to the fixed base 6 via the pin shaft 72. The sampling tube 4 passes through the through hole 74 and sequentially through the cover plate 71 and the retaining ring 75. The retaining ring 75 is secured to the bottom of the tube cap of the sampling tube 4. The retaining ring 75 is annular, and the inner diameter of the bottom of the retaining ring 75 is larger than the outer diameter of the sampling tube 4 but smaller than the outer diameter of the tube cap. This allows the inner tube cap of the sampling tube 4 to rest on the retaining ring 75 as it passes through the through hole 74. When the manual push rod rotates the cover plate 71 upward around the pin shaft 72, the cover plate 71... The retaining ring 75 is rotated upwards, which applies an upward pulling force to the tube cap. At this time, the sampling tube 4 remains stationary with respect to the box body 1 due to the friction of the rubber ring 3, causing the opening plate 71 to separate the sampling tube 4 from the tube cap. The rubber ring 3 is made of soft rubber to increase the friction between it and the sampling tube 4, making the static friction between the sampling tube 4 and the rubber ring 3 greater than the static friction between the sampling tube 4 and the tube cap, thus ensuring that the sampling tube 4 separates smoothly from the tube cap.

[0041] Furthermore, the insertion ring 77 is a ring with a right-angled trapezoidal longitudinal section. The inner wall of the insertion ring 77 is inclined. The insertion ring 77 is wider at the top and narrower at the bottom. The insertion ring 77 is connected to the slot 76 via a thread 79. The inner wall of the insertion ring 77 is in contact with the clamping block 711. By turning the insertion ring 77 with the knob 78, the insertion ring 77 rotates and descends in the slot 76 via the thread 79. The descent of the inner wall of the insertion ring 77 pushes 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 circumferentially at equal intervals in the through groove 710. The clamping block 711 contacts the outer wall of the tube cap of the sampling tube 4 via the rubber block 712. As the insertion ring 77 descends in the slot 76 and pushes 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 cap of the sampling tube 4 via the rubber block 712.

[0043] Furthermore, a groove 61 is provided on the upper surface of the fixing base 6. Limiting blocks 62 are connected to the inner walls of the front and rear sides of the groove 61. When the fixing block 713 rotates around the pin 72, it is movably inserted into the groove 61. The limiting block 62 is frustoconical. The fixing block 713 is engaged with the limiting block 62 via the protrusion 714. When a sample is taken, the opening plate 71 above the sample is pushed to rotate upward around the pin 72. At the same time, the opening plate 71 drives the fixing block 713 to insert into the groove 61. The fixing block 713 drives the protrusion 714 to press 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 restricts the protrusion 714 to reset, thereby fixing the upward rotation position of the opening plate 71.

[0044] Furthermore, the anti-detachment mechanism 9 includes a limiting plate 91. Slide plates 92 are connected to the bottom of the limiting plate 91 near its front and rear edges. Slots 93 are provided on both the front and rear side walls of the slide plates 92. A screw 94 passes through the center of the slide plates 92. The limiting plate 91 and the slide plates 92 are integrally connected. The top of the limiting plate 91 is bent at a right angle to form a rectangular plate with an L-shaped longitudinal section. Both the limiting plate 91 and the slide plates 92 are movably inserted into the sliding grooves 8. By inserting the slide plates 92 into the sliding grooves 8 on the left and right sides of the housing 1, the mechanism can be pushed... The sliding plate 92 slides down in the slide groove 8 until the top bend of the limiting plate 91 presses against the multiple opening plates 71, positioning the multiple opening plates 71. This effectively prevents the caps of the sampling tubes 4 from being accidentally opened due to collisions during the inspection process. The limiting plate 91, the sliding plate 92, and the box body 1 are detachably installed. When the tubes are being inspected, they are inserted into the slide groove 8. When the sampling tubes 4 are being stored, the limiting plate 91 and the sliding plate 92 are removed and placed aside. When not in use, they are fully inserted into the slide groove 8.

[0045] Furthermore, the inner walls of both the front and rear sides of the slide 8 are connected with locking blocks 81. A screw hole 82 is provided on the box 1 on one side of the slide 8. The locking block 81 is inserted into the movable slot of the locking groove 93. The locking block 81 and the locking groove 93 are used to make the slide plate 92 move up and down stably in the slide 8 and not fall out of the slide 8. The screw 94 passes through the slide plate 92 and is connected to the screw hole 82 by thread 79. The screw 94 passes through the slide plate 92 and is connected to the screw hole 82 to position the slider.

[0046] Furthermore, an inlet 10 is provided on the upper surface of the box 1 near the rear edge, and an outlet 11 is provided on the rear side wall of the box 1 for water to flow out of the insulation cavity 5. Both the inlet 10 and the outlet 11 are threaded with sealing caps 12. Both the inlet 10 and the outlet 11 are connected to the insulation cavity 5. The insulation cavity 5 contains warm water or ice water. Warm water or ice water is added into the insulation cavity 5 through the inlet 10. The wall of the sampling tube 4 is directly immersed in the water, providing the optimal preservation environment for the sample and ensuring that the collected sample is not affected by the ambient temperature.

[0047] Furthermore, a display screen 13 is installed on the front wall of the housing 1. The display screen 13 shows the temperature data of the water in the insulation chamber 5 and the timing of the timer 18. A start button 14 is installed on the front wall of the housing 1 on one side of the display screen 13. A microprocessor 15 is installed inside the housing 1 on the front side of the insulation chamber 5. The microprocessor 15 is electrically connected to the battery 16 and the timer 18. After the first sample tube is placed into the housing 1, the start button is pressed to record the time when the sample tube 4 is first placed in, so that medical staff can observe the storage time of the sample tube 4 for timely testing. 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 users can observe the temperature changes.

[0048] A method for using a sample collection and delivery device for a laboratory includes the following steps:

[0049] S1: The sampling tube 4 with the sample is passed through the through hole 74, through the cover plate 71 and the retaining ring 75, and inserted into the insertion hole 2. The sampling tube 4 is compressed and deformed by squeezing the rubber ring 3, and the bottom of the sampling tube 4 is inserted into the heat preservation cavity 5.

[0050] S2: Insert the insertion ring 77 into the slot 76 and rotate the insertion ring 77 by turning the knob 78, so that the insertion ring 77 rotates and descends in the slot 76 through the thread 79. The descending of the inner wall of the insertion ring 77 pushes multiple clamping blocks 711 to move in the through groove 710 until the multiple clamping blocks 711 clamp the side wall of the tube cap of the sampling tube 4 through the rubber block 712.

[0051] S3: Press the start button to record the time when the sampling tube 4 is first placed in the sample tube. The start button inputs a command to the microprocessor 15, and the microprocessor 15 controls the timer 18 to start timing.

[0052] S4: According to the preservation characteristics of the sample, warm water or ice water is added into the insulation chamber 5 from the water inlet 10 to provide the optimal preservation environment for the sample. 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.

[0053] S5: Before the timer 18 ends, insert the slide plate 92 into the slide groove 8. The slide plate 92 slides down in the slide groove 8 until the top bend of the limit plate 91 just presses on the multiple opening plates 71. Then, use the screw 94 to connect the slide plate 92 and the screw hole 82 to position the slider and transfer the box 1 to the detection point.

[0054] S6: Loosen screw 94 to remove limit plate 91. When taking a sample, push the opening plate 71 above the sample to flip upward around pin 72. Opening plate 71 drives the retaining ring 75 to flip upward. With the action of clamping block 711 and retaining ring 75, pull the sampling tube 4 to separate from the tube cover. At the same time, opening plate 71 drives fixing block 713 to insert into groove 61. Fixing block 713 is engaged with limit block 62 through protrusion 714 to fix the position of opening plate 71 flipping upward.

[0055] S7: Use a pipette to take a sample from the sampling tube 4 for subsequent testing. After sampling, push the cap plate 71 downwards to reset it. The cap plate 71 will then put the tube cap back on the sampling tube 4 to prevent contamination.

[0056] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
