Description

Technical Field

[0001] The present invention relates to the technical field of specimen storage boxes, and specifically to a storage device for transferring blood collection tubes. Background Art

[0002] When doctors diagnose patients' diseases, sometimes blood collection is required for examination. During the blood collection process, the blood collection nurse needs to scan the patient's wristband to verify the blood collection information. After verification, operate the computer and label printer to print labels, take out the corresponding color vacuum blood collection tubes, classify the vacuum blood collection tubes according to the blood collection guidelines, and paste labels on the corresponding color vacuum blood collection tubes. After blood collection, it is necessary to uniformly transfer the blood collection tubes to the laboratory department.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a storage device for transferring blood collection tubes, which has the following beneficial effects:

[0018] 1. The storage device for transferring blood collection tubes sucks the air inside the negative pressure chamber through an air pump, and conveys the air to the positive pressure chamber through a conduit and air vents; thereby making the inside of the negative pressure chamber and the piston chamber in a negative pressure state, and the inside of the positive pressure chamber in a positive pressure state; and through the negative pressure effect, the base is adsorbed at the adsorption holes; as the air pressure inside the piston chamber gradually decreases, the sliding piston moves downward, the first spring is squeezed and contracted, the vertical plate squeezes the sliding column at the inner wall of the inclined groove, and pushes the sliding plate to move horizontally relative to the spacer plate. The sliding plate pushes the rotating arm, the rotating shaft, the reinforcing rod and the clamping rod to deflect, so that the clamping rod fits on the side of the blood collection tube, thereby achieving the purpose of clamping and fixing the blood collection tube, avoiding the blood collection tube from shaking and colliding during transportation, and suppressing the blood inside the blood collection tube from leaking from the gap between the blood collection tube and the tube cap through the air pressure inside the positive pressure chamber;

[0019] 2. When the rotating arm, the rotating shaft, the reinforcing rod and the clamping rod of the storage device for transferring blood collection tubes deflect, the leftmost and rightmost clamping rods push the transverse frame downward, driving the sliding seat to move downward, so that the extension arm and the first rack move downward. The first rack drives the first gear and the second gear to rotate at the same angular velocity, and through the meshing action of the second gear and the second rack, drives the second rack to move downward; the second rack then pulls the cover plate downward, so that the square rubber tube is squeezed on the top of the blood collection tube, and the square rubber tube and the rubber strip are squeezed and deformed, thereby limiting the blood collection tube in the vertical direction. Thus, the purpose of further fixing the blood collection tube is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Please refer to Figures 1 - 4 , a storage device for transferring blood collection tubes, including a storage box 100. A pick-up and placement opening is provided on the front side of the storage box 100. A sealing door 200 for sealing the pick-up and placement opening is inserted on the front side of the storage box 100. A support plate 300 is fixedly installed on the inner wall of the storage box 100. The support plate 300 divides the storage box 100 into upper and lower parts. The upper part is a positive pressure chamber, and the lower part is a negative pressure chamber. An air extraction assembly 500 is arranged in the negative pressure chamber. The air extraction assembly 500 is used to convey the air inside the negative pressure chamber into the positive pressure chamber; thereby enabling 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. Spacing plates 400 are fixedly arranged in an array on the top of the support plate 300. A receiving groove is formed between two adjacent spacing plates 400. A blood collection tube bracket 600 is inserted into each receiving groove, and blood collection tubes are stored in the blood collection tube bracket 600. Side clamping members 700 are arranged on both sides of each spacing plate 400, and the side clamping members 700 clamp the sides of the blood collection tubes. Pulling assemblies 800 are arranged on the left and right inner walls of the storage box 100. A top pressing member 900 is arranged between the tops of the two pulling assemblies 800, and the top pressing member 900 is attached to the tops of the blood collection tubes.

[0036] Please refer to Figure 5, the blood collection tube holder 600 includes an upper U-shaped rod 601, a middle U-shaped rod 602 and a lower U-shaped rod 603. The upper U-shaped rod 601, the middle U-shaped rod 602 and the lower U-shaped rod 603 are all U-shaped. 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. 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. A base 606 is fixedly arranged in an array at the bottom of the lower U-shaped rod 603. An inclined rod 607 is integrally formed at the front end of the upper U-shaped rod 601. The blood collection tube is inserted and accommodated inside the upper U-shaped rod 601 and the middle U-shaped rod 602, and the tube cap of the blood collection tube fits on the top of the upper U-shaped rod 601. And through the arrangement of the inclined rod 607, when the tube cap of the blood collection tube fits on the top of the inclined rod 607, the blood collection tube has a tendency to move into the upper U-shaped rod 601. Blood collection tubes of the same color can be stored in the same blood collection tube holder 600, so as to store different colors of blood collection tubes separately.

[0037] Please refer to Figures 2 - 4 and Figure 7 , the top of the tray 300 is flush with the bottom wall of the access opening, which is convenient for the blood collection tube holder 600 to be inserted into the receiving groove and smoothly transition from the access opening to the tray 300. A rear baffle 301 is fixedly installed at the top of the rear end of the tray 300. Arc-shaped grooves 302 are 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-shaped grooves 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-shaped grooves 302. When the blood collection tube holder 600 is inserted into the inside of the receiving groove, when the blood collection tube holder 600 fits at the arc-shaped grooves 302, it reminds the blood collection nurse that the blood collection tube holder 600 has been inserted to the deepest position.

[0038] A row of adsorption holes 303 are penetrated and opened in the middle of the top of the pallet 300. When the blood collection tube holder 600 is inserted into the accommodation groove, one of the bases 606 seals the adsorption hole 303. After the air inside the suction negative pressure chamber is pumped out, the base 606 is adsorbed at the adsorption hole 303 through the negative pressure action of the negative pressure chamber, and the blood collection tube holder 600 is limited. A row of first communication holes 304 are penetrated and arrayed on the top of the pallet 300, and the first communication holes 304 are distributed in a matrix. A piston chamber 401 is arranged inside each partition plate 400, and a column of second communication holes 402 are penetrated and opened at the bottom of the piston chamber 401. The piston chamber 401 is communicated with the negative pressure chamber through the second communication holes 402 and the first communication holes 304. Therefore, after the air inside the suction negative pressure chamber is pumped out, the inside of the piston chamber 401 is also in a negative pressure state through the communication action of the second communication holes 402 and the first communication holes 304. Slots 403 are opened on the left and right sides at 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 accommodation groove, the base 606 is inserted into the slots 403 to limit the base 606, thereby restraining the left and right movement and up and down movement of the blood collection tube holder 600.

[0039] Please refer to Figure 2 , the air extraction assembly 500 includes an air pump 501 arranged in the negative pressure chamber. The output end of the air pump 501 is connected with an air duct 502, and the other end of the air duct 502 is connected to the bottom of the rear end of the pallet 300. An air guide hole 503 is penetrated and opened at the top of the rear baffle 301. The air guide hole 503 penetrates the pallet 300 and is communicated with the air duct 502. Therefore, the air inside the suction negative pressure chamber is pumped out by the air pump 501, and then the air is conveyed into the positive pressure chamber through the air duct 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.

[0040] Please refer to Figures 6 - 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. A clamping rod 704 is fixedly installed between the top ends of the two rotating arms 701. A row of sliding plates 705 are rotatably connected to each reinforcing rod 703. The number of the sliding plates 705 is three. The sliding plates 705 are slidably connected through the partition plate 400 and extend into the piston chamber 401.

[0041] The side clamp 700 further includes a sliding piston 706 slidably connected inside 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. Due to the elasticity of the elastic support member 707, the sliding piston 706 has a tendency to move upward. 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.

[0042] A sliding column 7051 is fixedly installed at one end of the sliding plate 705 located inside the piston chamber 401. Six inclined grooves 7064 are formed 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 inside the inclined grooves 7064. Thus, when the sliding piston 706 moves downward, the sliding piston 706 presses against the sliding column 7051 at the inner wall of the inclined grooves 7064, pushing the sliding plate 705 to move horizontally, and deflecting the clamping frame through the sliding plate 705 so that the clamping frame fits on the blood collection tube to fix the blood collection tube.

[0043] Please refer to Figures 8 - 9 As shown, 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. A lower piston plate 7063 is fixedly installed at the bottom of the three vertical plates 7062. The inclined grooves 7064 are formed through the lower piston plate 7063. Thus, 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.

[0044] The elastic support member 707 includes a mounting seat 7071 fixedly installed 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 first guide rods 7072 are fixedly installed at the top of the mounting seat 7071. The first guide rods 7072 penetrate through the lower piston plate 7063, and the lower piston plate 7063 is slidably connected to the first guide rods 7072 to guide the lower piston plate 7063 through the first guide rods 7072. A first spring 7073 is sleeved outside the first guide rods 7072. Two ends of the first spring 7073 are respectively fixedly installed at the top of the mounting seat 7071 and the bottom of the lower piston plate 7063. Due to the elasticity of the first spring 7073, the lower piston plate 7063 has a tendency to move upward. When the upper piston plate 7061, the vertical plates 7062, and the lower piston plate 7063 move downward, the first spring 7073 is compressed and contracted.

[0045] Please refer to Figures 6 - 8, rubber rings 708 are fixedly arranged in an array on the surface of the clamping rod 704, and blood collection tubes are separated by the rubber rings 708 to inhibit the movement of the blood collection tubes in the front-back direction. A corrugated rubber tube 709 is sleeved outside each sliding plate 705. One end of the corrugated rubber tube 709 is fixedly installed on the surface of the sliding plate 705, and the other end of the corrugated rubber tube 709 is fixedly installed on the side surface of the spacer plate 400. When the sliding plate 705 moves relative to the spacer plate 400 in the horizontal direction, the corrugated rubber tube 709 contracts or extends. And through the arrangement of the corrugated rubber tube 709, it is avoided that the gap at the connection between the spacer plate 400 and the sliding plate 705 communicates with the positive pressure chamber.

[0046] Please refer to Figures 10 - 12 , each pulling assembly 800 includes a sliding seat 801. Two linear grooves 802 are formed through the surface of the sliding seat 801. Two fixed columns 803 are fixedly installed on the left inner wall and the right inner wall of the storage box 100. The sliding seat 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 sliding seat 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 sliding seat 801, and the clamping rod 704 passes through the transverse frames 804. Thus, when the rotating arm 701 deflects downward, the clamping rod 704 squeezes the transverse frames 804 downward, driving the sliding seat 801 to slide downward relative to the fixed columns 803 and squeezing the second spring 805.

[0047] An extension arm 806 is fixedly installed on the front side and the rear side of the bottom end of the sliding seat 801. A first rack 807 is fixedly installed at the other end of the extension arm 806. The first rack 807 meshes with a first gear 808, and the first gear 808 is rotatably connected to the storage box 100. Thus, when the sliding seat 801 moves downward, the first gear 808 is driven to rotate. The first gear 808 is coaxially fixed with a second gear 809. A second rack 810 is meshed with one side of each of the two second gears 809. The top end of the second rack 810 is fixedly installed on the top pressing member 900. The first gear 808 and the second gear 809 rotate synchronously. Since the diameter of the second gear 809 is larger than the diameter of the first gear 808, the second rack 810 moves downward, and the moving distance of the second rack 810 is greater than the moving distance of the first rack 807. Thus, the top pressing member 900 moves downward following the sliding seat 801, and the moving distance of the top pressing member 900 is greater than the moving distance of the sliding seat 801.

[0048] Please refer to Figure 10, the top squeezer 900 includes four second guide rods 901. Two second guide rods 901 are fixedly installed at the top of the leftmost spacer 400 and the top of the rightmost spacer 400 respectively. A cover plate 902 is slidably connected to the four second guide rods 901. A second rack 810 is fixedly installed on the cover plate 902. Square rubber tubes 903 are fixedly arranged in an array at the bottom of the cover plate 902. The square rubber tubes 903 correspond to the blood collection tube holders 600 one by one. Rubber strips 904 are fixedly arranged in an array along the vertical direction on the inner wall of the square rubber tube 903. The cross-section of the rubber strip 904 is V-shaped. Initially, under the elastic action of the second spring 805, the slide block 801 is in a higher position. Thus, through the connection of the second rack 810, the square rubber tube 903 is located above the blood collection tube holder 600. When the slide block 801 moves downward, the cover plate 902 is pulled downward through the second rack 810. Thus, the square rubber tube 903 squeezes on the top of the blood collection tube. Under the squeezing action, the square rubber tube 903 and the rubber strip 904 are deformed. The square rubber tube 903 elastically abuts against the top of the blood collection tube, inhibiting the blood collection tube from moving in the vertical direction.

[0049] During use, the same color of blood collection tubes are placed inside each blood collection tube holder 600. Then, the blood collection tube holder 600 is inserted into the accommodation groove through the access opening of the storage box 100. Then, the sealing door 200 is slid downward to seal the access opening of the storage box 100;

[0050] The air pump 501 sucks the air inside the negative pressure chamber and conveys the air to the positive pressure chamber through the air guide pipe 502 and the air guide holes 503; thus, 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 through the negative pressure action, the base 606 is adsorbed at the adsorption holes 303;

[0051] As the air pressure inside the piston chamber 401 gradually decreases, the sliding piston 706 moves downward, the first spring 7073 is squeezed and contracted. The vertical plate 7062 squeezes the sliding column 7051 at the inner wall of the inclined groove 7064 and pushes the sliding plate 705 to move horizontally relative to the spacer 400. 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 on the side of the blood collection tube, thereby clamping and fixing the blood collection tube;

[0052] During the deflection of the swing arm 701, the rotating shaft 702, the reinforcing rod 703 and the clamping rod 704, the leftmost and rightmost clamping rods 704 push the transverse frame 804 downward, driving the sliding seat 801 to move downward, so that the extension arm 806 and the first rack 807 move downward. The first rack 807 drives the first gear 808 and the second gear 809 to rotate at the same angular velocity, and through the meshing action of the second gear 809 and the second rack 810, drives the second rack 810 to move downward; the second rack 810 then pulls the cover plate 902 downward, pressing the square rubber tube 903 against the top of the blood collection tube. The square rubber tube 903 and the rubber strip 904 are deformed by extrusion, so as to limit the blood collection tube in the vertical direction.

[0053] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
