[0002] When doctors diagnose patients' illnesses, they sometimes need to draw blood for testing. During the blood collection process, the blood collection nurse needs to scan the QR code on the patient's wristband to verify the blood collection information. After verification, the nurse needs to operate the computer and label printer to print labels, take out vacuum blood collection tubes of corresponding colors, classify the vacuum blood collection tubes according to the blood collection guide, and affix labels to the vacuum blood collection tubes of corresponding colors. After the blood collection is completed, the blood collection tubes need to be transferred to the laboratory department.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

An exhaust component 500 is provided in the negative pressure chamber, and the exhaust component 500 is used to transport the air inside the negative pressure chamber to the positive pressure chamber; thereby allowing the air inside the negative pressure chamber to enter the positive pressure chamber, reducing the air pressure in the negative pressure chamber and increasing the air pressure in the positive pressure chamber. A partition plate 400 is fixed in an array on the top of the support plate 300, and a receiving groove is formed between two adjacent partition plates 400, and a blood collection tube holder 600 is plugged into each receiving groove, and blood collection tubes are stored in the blood collection tube holder 600. Each partition plate 400 is provided with side clamps 700 on both sides, and the side clamps 700 clamp the side of the blood collection tube. Pulling components 800 are provided on the left and right inner walls of the storage box 100, and a top extrusion component 900 is provided between the tops of the two pulling components 800, and the top extrusion component 900 is attached to the top of the blood collection tube.

[0020] See also Figure 5The blood collection tube support 600 includes an upper U-shaped rod 601, a middle U-shaped rod 602 and a lower U-shaped rod 603, all of which are U-shaped, and a front connecting rod 604 is fixedly installed between the front ends of the upper U-shaped rod 601, the middle U-shaped rod 602 and the lower U-shaped rod 603, and a rear connecting rod 605 is fixedly installed between the rear ends of the upper U-shaped rod 601, the middle U-shaped rod 602 and the lower U-shaped rod 603, and a base 606 is fixedly arranged at the bottom of the lower U-shaped rod 603, and a tilting rod 607 is integrally formed at the front end of the upper U-shaped rod 601. The blood collection tube is inserted and accommodated in the upper U-shaped rod 601 and the middle U-shaped rod 602, and the tube cap of the blood collection tube is attached to the top of the upper U-shaped rod 601. By setting the inclined rod 607, when the tube cap of the blood collection tube is attached to the top of the inclined rod 607, the blood collection tube has a tendency to move upward inside the U-shaped rod 601. Blood collection tubes of the same color can be stored in the same blood collection tube holder 600, so that blood collection tubes of different colors can be stored by classification.

[0021] See also Figure 2-Figure 4 and Figure 7 , the top of the support plate 300 is flush with the bottom wall of the access port, so that when the blood collection tube holder 600 is inserted into the receiving slot, it can smoothly transition from the access port to the support plate 300. A rear baffle 301 is fixedly installed on the top of the rear end of the support plate 300, and an arc groove 302 is arranged in an array on the front side of the rear baffle 301. The rear end of the blood collection tube holder 600 fits on the arc groove 302, that is, the rear ends of the upper U-shaped rod 601, the middle U-shaped rod 602 and the lower U-shaped rod 603 are adapted to the arc groove 302. When the blood collection tube holder 600 is inserted into the receiving slot, when the blood collection tube holder 600 fits on the arc groove 302, it reminds the blood collection nurse that the blood collection tube holder 600 has been inserted to the deepest point.

[0022] A row of adsorption holes 303 is provided in the middle of the top of the support plate 300. When the blood collection tube holder 600 is inserted into the receiving groove, one of the bases 606 seals the adsorption hole 303. After the air inside the negative pressure chamber is sucked, the base 606 is adsorbed on the adsorption hole 303 by the negative pressure of the negative pressure chamber, and the blood collection tube holder 600 is limited. The top array of the support plate 300 is provided with a connecting hole 1 304, and the connecting holes 1 304 are distributed in a matrix. A piston chamber 401 is provided inside each partition plate 400, and a row of connecting holes 2 402 is provided at the bottom of the piston chamber 401. The piston chamber 401 is connected to the negative pressure chamber through the connecting hole 2 402 and the connecting hole 1 304, so that after the air inside the negative pressure chamber is sucked, the inside of the piston chamber 401 is also in a negative pressure state through the connecting effect of the connecting hole 2 402 and the connecting hole 1 304. Slots 403 are provided on both the left and right sides of the bottom of the partition plate 400, and the bottom of the blood collection tube holder 600 is inserted into the slots 403. Therefore, when the blood collection tube holder 600 is inserted into the receiving groove, the base 606 is inserted into the slot 403, and the base 606 is limited, thereby preventing the blood collection tube holder 600 from moving left and right and up and down.

[0023] See also Figure 2 The air extraction component 500 includes an air pump 501 disposed in the negative pressure chamber, the output end of the air pump 501 is connected to an air guide tube 502, the other end of the air guide tube 502 is connected to the bottom of the rear end of the support plate 300, and an air guide hole 503 is provided through the top of the rear baffle 301, the air guide hole 503 penetrates the support plate 300 and is connected to the air guide tube 502. Thus, the air inside the negative pressure chamber is sucked by the air pump 501, and then the air is transported to the positive pressure chamber through the air guide tube 502 and the air guide hole 503. The air pressure inside the positive pressure chamber is increased, and under the action of the air pressure, the blood inside the blood collection tube is prevented from leaking from the gap between the blood collection tube and the tube cap.

[0024] See also Figure 6-Figure 9 The side clamping member 700 includes two sets of clamping frames rotatably connected to the left and right sides of the partition plate 400. Each clamping frame includes two rotating arms 701 hinged to the side of the partition plate 400, a rotating shaft 702 is fixedly installed between the bottom ends of the two rotating arms 701, a reinforcing rod 703 is fixedly installed between the middle parts of the two rotating arms 701, and a clamping rod 704 is fixedly installed between the top ends of the two rotating arms 701. Each reinforcing rod 703 is rotatably connected to a row of sliding plates 705, the number of sliding plates 705 is three, and the sliding plates 705 penetrate and slide on the partition plate 400 and extend into the piston cavity 401.

[0025] The side clamping member 700 further includes a sliding piston 706 slidably connected to the piston chamber 401. An elastic support member 707 is provided between the bottom of the sliding piston 706 and the inner wall of the piston chamber 401. The sliding piston 706 has a tendency to move upward due to the elasticity of the elastic support member 707. When the air inside the negative pressure chamber is sucked into the positive pressure chamber, the air pressure inside the piston chamber 401 decreases, causing the sliding piston 706 to move downward inside the piston chamber 401.

[0026] A sliding column 7051 is fixedly mounted on one end of the sliding plate 705 located inside the piston chamber 401. Six inclined grooves 7064 are provided on the surface of the sliding piston 706. Every two inclined grooves 7064 form a group and are in an inverted "eight" shape. The sliding column 7051 is slidably connected in the inclined groove 7064. Therefore, when the sliding piston 706 moves downward, the sliding piston 706 is located at the inner wall of the inclined groove 7064 to squeeze the sliding column 7051, pushing the sliding plate 705 to move in the horizontal direction, and pushing the clamping frame to deflect through the sliding plate 705, so that the clamping frame fits on the blood collection tube to fix the blood collection tube.

[0027] See also Figure 8-Figure 9 The sliding piston 706 includes an upper piston plate 7061, three vertical plates 7062 are fixedly installed at the bottom of the upper piston plate 7061, and a lower piston plate 7063 is fixedly installed at the bottom of the three vertical plates 7062. The inclined groove 7064 is opened through the lower piston plate 7063. Therefore, when the air pressure inside the piston chamber 401 decreases, the upper piston plate 7061, the vertical plates 7062 and the lower piston plate 7063 slide downward inside the piston chamber 401.

[0028] The elastic support member 707 includes a mounting seat 7071 fixedly mounted on the inner wall of the piston chamber 401. The length of the mounting seat 7071 is less than the length of the piston chamber 401. Two guide rods 1 7072 are fixedly mounted on the top of the mounting seat 7071. The guide rods 1 7072 penetrate the lower piston plate 7063. The lower piston plate 7063 is slidably connected to the guide rods 1 7072, and the lower piston plate 7063 is guided by the guide rods 1 7072. A spring 1 7073 is sleeved on the outer side of the guide rod 1 7072. The two ends of the spring 1 7073 are respectively fixedly mounted on the top of the mounting seat 7071 and the bottom of the lower piston plate 7063. The elasticity of the spring 1 7073 makes the lower piston plate 7063 have a tendency to move upward. When the upper piston plate 7061, the vertical plate 7062 and the lower piston plate 7063 move downward, the spring 1 7073 is squeezed and contracted.

[0029] See also Figure 6-Figure 8, the surface of the clamping rod 704 is fixed with an array of rubber rings 708, which separate the blood collection tubes and inhibit the blood collection tubes from moving in the front-back direction. A corrugated rubber tube 709 is sleeved on the outside of each sliding plate 705, one end of the corrugated rubber tube 709 is fixedly mounted on the surface of the sliding plate 705, and the other end of the corrugated rubber tube 709 is fixedly mounted on the side of the partition plate 400. When the sliding plate 705 moves horizontally relative to the partition plate 400, the corrugated rubber tube 709 contracts or stretches. And by setting the corrugated rubber tube 709, it is prevented that the gap at the connection between the partition plate 400 and the sliding plate 705 is connected to the positive pressure chamber.

[0030] See also Figure 10-12 Each pulling assembly 800 includes a slide 801, and two linear grooves 802 are formed on the surface of the slide 801. Two fixed columns 803 are fixedly installed on the left inner wall and the right inner wall of the storage box 100. The slide 801 is slidably connected to the fixed columns 803 through the linear grooves 802. A second spring 805 is fixedly installed at the bottom of the slide 801, and the bottom end of the second spring 805 is fixedly installed on the inner wall of the storage box 100. Two transverse frames 804 are fixedly installed at the bottom end of the slide 801, and the clamping rod 704 passes through the transverse frame 804. Therefore, when the rotating arm 701 deflects downward, the clamping rod 704 presses the transverse frame 804 downward, drives the slide 801 to slide downward relative to the fixed column 803, and presses the second spring 805.

[0031] The front and rear sides of the bottom of the slide 801 are fixedly mounted with an extension arm 806, and the other end of the extension arm 806 is fixedly mounted with a rack 807, and the rack 807 is meshed with a gear 808, and the gear 808 is rotatably connected to the storage box 100, so that when the slide 801 moves downward, the gear 808 is driven to rotate. The gear 808 is coaxially fixed with a gear 809, and the opposite sides of the two gears 809 are meshed with a rack 810, and the top of the rack 810 is fixedly mounted on the top extrusion member 900. The gear 808 and the gear 809 rotate synchronously, and because the diameter of the gear 809 is larger than the diameter of the gear 808, the rack 810 moves downward, and the moving distance of the rack 810 is greater than the moving distance of the rack 807. Therefore, the top extrusion member 900 moves downward with the slide 801, and the moving distance of the top extrusion member 900 is greater than the moving distance of the slide 801.

[0032] See also Fig.10The top extrusion piece 900 includes four guide rods 2 901. Two guide rods 2 901 are fixedly installed on the top of the leftmost partition plate 400 and the top of the rightmost partition plate 400. The four guide rods 2 901 are slidably connected with a cover plate 902. The rack 2 810 is fixedly installed on the cover plate 902. A square rubber tube 903 is fixed in an array at the bottom of the cover plate 902. The square rubber tube 903 corresponds to the blood collection tube support 600 one by one. The inner wall of the square rubber tube 903 is fixed with a rubber strip 904 in an array along the vertical direction. The cross section of the rubber strip 904 is V-shaped. At the beginning, under the elastic action of the spring 2 805, the slide seat 801 is at a higher position, so that the square rubber tube 903 is located above the blood collection tube support 600 through the connection action of the rack 2 810. When the slide 801 moves downward, the cover plate 902 is pulled downward by the rack 2 810, so that the square rubber tube 903 is squeezed on the top of the blood collection tube, and under the squeezing effect, the square rubber tube 903 and the rubber strip 904 are deformed, so that the square rubber tube 903 elastically abuts on the top of the blood collection tube, inhibiting the blood collection tube from moving in the vertical direction.

[0033] When in use, blood collection tubes of the same color are placed inside each blood collection tube holder 600, and then the blood collection tube holder 600 is inserted into the receiving slot through the access opening of the storage box 100, and then the sealing door 200 is slid downward to seal the access opening of the storage box 100; The air in the negative pressure chamber is sucked by the air pump 501, and the air is transported to the positive pressure chamber through the air guide tube 502 and the air guide hole 503; so that the negative pressure chamber and the piston chamber 401 are in a negative pressure state, and the positive pressure chamber is in a positive pressure state; and the base 606 is adsorbed on the adsorption hole 303 by the negative pressure; As the air pressure inside the piston chamber 401 gradually decreases, the sliding piston 706 moves downward, the spring 1 7073 is squeezed and contracted, the vertical plate 7062 is located at the inner wall of the inclined groove 7064 to squeeze the sliding column 7051, and push the sliding plate 705 to move horizontally relative to the partition plate 400, and the sliding plate 705 pushes the rotating arm 701, the rotating shaft 702, the reinforcing rod 703 and the clamping rod 704 to deflect, so that the clamping rod 704 fits the side of the blood collection tube, thereby clamping and fixing the blood collection tube; During the deflection of the rotating arm 701, the rotating shaft 702, the reinforcing rod 703 and the clamping rod 704, the leftmost and rightmost clamping rods 704 push the horizontal frame 804 downward, driving the slide 801 to move downward, thereby causing the extension arm 806 and the rack 1 807 to move downward, and the rack 1 807 drives the gear 1 808 and the gear 2 809 to rotate at the same angular velocity, and drives the rack 2 810 to move downward through the meshing action of the gear 2 809 and the rack 2 810; the rack 2 810 then pulls the cover plate 902 downward, so that the square rubber tube 903 is squeezed on the top of the blood collection tube, and the square rubber tube 903 and the rubber strip 904 are squeezed and deformed, thereby limiting the blood collection tube in the vertical direction.
