Description

Technical Field

[0001] This utility model relates to the field of blood collection rack technology, and in particular to a PRP mobile blood collection rack. Background Technology

[0002] In clinical blood collection, especially during platelet-rich plasma (PRP) collection, accurate weighing of the collected blood samples is crucial. Current procedures often involve temporarily placing the electronic scale and blood bag on a blood collection stool for weighing and blood transfer. However, this method has significant drawbacks: the blood collection stool lacks a fixed structure, making it prone to displacement when nurses place or retrieve the scale and blood bag, leading to fluctuations in weighing data, blood bag slippage, and even sample contamination risks. The current common solution is to have another nurse hold and stabilize the blood collection stool throughout the process. This approach not only requires additional manpower and reduces blood collection efficiency but also, in emergency situations or when multiple patients are collecting blood simultaneously, can lead to insufficient manpower and compromised operational standardization. Therefore, this invention proposes a mobile PRP blood collection stand. Utility Model Content

[0003] The purpose of this invention is to address the problems in the existing clinical PRP collection process, where electronic scales and blood bags are placed on blood collection stools without a fixed structure, which can easily lead to displacement, inaccurate weighing, and sample contamination. Furthermore, the process requires a dedicated person to fix the scales, which consumes manpower and affects efficiency and standardization. Therefore, this invention proposes a mobile PRP blood collection rack.

[0004] The technical solution of this utility model is as follows: A PRP mobile blood collection rack includes a placement platform for placing an electronic scale; a vertical pole disposed on one side of the placement platform; a locking component located on the outside of the vertical pole, the locking component being used to adjust the position of the vertical pole; and a clamping mechanism installed on the vertical pole, the clamping mechanism being used to clamp and fix the blood collection tube.

[0007] Optionally, the outer ring of the limiting rod is fitted with two sets of first springs, and the two sets of first springs are respectively located on the opposite side of the two sets of moving blocks.

[0008] Optionally, two sets of limiting blocks are provided on opposite sides of the two sets of moving blocks, and the limiting blocks are fixedly connected to the inside of the fixed frame.

[0009] Optionally, a positioning component for adjusting the friction force when the rotating block rotates is also included.

[0010] Optionally, the positioning component includes a compression sleeve slidably connected to the outer ring of the upright, a rubber ring installed on the side of the compression sleeve near the rotating block, the rubber ring contacting the rotating block, and multiple sets of sliding rods installed on the side of the compression sleeve away from the rotating block. Each set of sliding rods has a fixing plate slidably connected to its outer ring, and each set of fixing plates is fixedly connected to the outside of the upright.

[0011] Optionally, a second spring is fitted around the outer ring of the slide rod, the second spring being located between the compression sleeve and the fixing plate, and a limit plate is installed at the end of the slide rod away from the compression sleeve.

[0033] Example

[0034] like Figure 1 As shown, the present invention proposes a mobile PRP blood collection rack, including a platform 1 for placing an electronic scale. Support legs 11 are fixedly connected to the bottom of the platform 1 for supporting it. A railing 12 is installed on the top of the platform 1 to prevent the electronic scale and blood bags placed on it from falling.

[0035] Furthermore, the aforementioned blood collection frame includes a vertical pole 2 installed on one side of the placement platform 1.

[0036] For further details, please refer to Figure 3 The blood collection frame also includes a locking assembly 3 located outside the upright 2. The locking assembly 3 is used to adjust the position of the upright 2. The locking assembly 3 includes a fixing sleeve 31 fixedly connected to the side of the placement platform 1, and the position of the fixing sleeve 31 is fixed. The upright 2 is slidably connected to the fixing sleeve 31. A threaded rod 32 is threadedly connected to one side of the fixing sleeve 31. After rotation, the threaded rod 32 moves along its own length direction, so that one end of the threaded rod 32 presses against the upright 2, thereby fixing the position of the upright 2. A knob 33 is fixedly connected to the end of the threaded rod 32 away from the upright 2. The knob 33 is designed to facilitate the rotation of the threaded rod 32.

[0037] Specifically, such as Figure 2 and Figure 4As shown, the blood collection frame includes a clamping mechanism 4 mounted on the upright 2, which is used to clamp and fix the blood collection tubes. The clamping mechanism 4 includes a fixing block 41 fixedly connected to the outer ring of the upright 2. A rotating block 42 is rotatably connected to the outer ring of the fixing block 41, so that the rotating block 42 is rotatably connected to the outer ring of the upright 2 through the fixing block 41. A fixing frame 43 is fixedly connected to one side of the rotating block 42. The fixing frame 43 is U-shaped. Two sets of limiting rods 44 are fixedly connected in the fixing frame 43. Two sets of moving blocks 45 are slidably connected to the two sets of limiting rods 44. The two sets of moving blocks 45 move smoothly under the limiting action of the limiting rods 44. A mounting plate 46 is fixedly connected to the side of the moving block 45 away from the rotating block 42. When the mounting plate 46 moves, it drives the moving block 45 to move synchronously. Arc-shaped plates 47 are installed on opposite sides of the two sets of mounting plates 46. The two sets of arc-shaped plates 47 are symmetrically arranged and are used to clamp the blood collection tubes. Two sets of first springs 48 are sleeved on the outer ring of the limiting rod 44. The two sets of first springs 48 are located on opposite sides of the two sets of moving blocks 45. The elastic force of the first springs 48 drives the two sets of moving blocks 45 to move closer to each other, thereby bringing the two sets of mounting plates 46 closer together to ensure clamping stability. Two sets of limiting blocks 49 are provided on opposite sides of the two sets of moving blocks 45. The limiting blocks 49 are fixedly connected to the inner side of the fixed frame 43, and limit the minimum distance between the two sets of moving blocks 45.

[0038] Furthermore, the aforementioned blood collection frame also includes a positioning component 5 for adjusting the friction force when the rotating block 42 rotates. The positioning component 5 includes a compression sleeve 51 slidably connected to the outer ring of the upright 2. A rubber ring 52 is installed on the side of the compression sleeve 51 near the rotating block 42, and the rubber ring 52 contacts the rotating block 42. The compression sleeve 51 drives the rubber ring 52 to compress the rotating block 42, increasing the friction force when the rotating block 42 rotates. Multiple sets of sliding rods 53 are installed on the side of the compression sleeve 51 away from the rotating block 42, and the sliding rods 53 move synchronously with the compression sleeve 51. A fixing plate 54 is slidably connected to the outer ring of each set of sliding rods 53. The fixing plates 54 are fixedly connected to the outside of the upright 2, and their positions are fixed. They work in conjunction with the sliding rods 53 to limit the movement of the compression sleeve 51, ensuring smooth movement of the compression sleeve 51. A second spring 55 is fitted around the outer ring of the slide rod 53. The second spring 55 is located between the compression sleeve 51 and the fixed plate 54. The elastic force of the second spring 55 causes the compression sleeve 51 to approach and compress the rotating block 42. A limit plate 56 is installed at the end of the slide rod 53 away from the compression sleeve 51. Multiple sets of connecting rods 57 are fixedly connected to the end of the compression sleeve 51 away from the rotating block 42. A movable ring 58 is fixedly connected to one end of the multiple sets of connecting rods 57. The movable ring 58 is fitted around the outer ring of the upright rod 2. Multiple protrusions are provided on the outer ring of the movable ring 58. The movable ring 58 drives the compression sleeve 51 to move through the connecting rods 57, so that the compression sleeve 51 moves away from the rotating block 42, facilitating the rotation of the rotating block 42.

[0039] In this embodiment, the electronic scale is first placed on the placement platform 1, and the railing 12 is used to prevent it from slipping. The threaded rod 32 is rotated by the knob 33 to adjust the height of the upright 2 in the fixing sleeve 31 to a suitable position, and the threaded rod 32 is tightened to compress and fix the upright 2. The blood bag is then gently placed on the placement platform 1 for later use, without the need for additional personnel to secure it.

[0040] During blood collection, medical staff hold the protruding structure of the movable ring 58, overcoming the elastic force of the second spring 55 to pull and compress the sleeve 51. The rubber ring 52 disengages from the rotating block 42, allowing the fixed frame 43 to be rotated flexibly to adjust the angle of the clamping mechanism 4. One set of mounting plates 46 is pushed by hand, causing one set of arc-shaped plates 47 to move away from the other set of arc-shaped plates 47. Simultaneously, the mounting plate 46 causes the movable block 45 to compress the first spring 48. The blood collection tube is then placed between the two sets of arc-shaped plates 47. Releasing the hand releases the elastic force of the first spring 48, causing one set of arc-shaped plates 47 to move closer to the other set of arc-shaped plates 47 to clamp the blood collection tube. The limiting block 49 restricts the minimum distance between the arc-shaped plates 47 to prevent excessive compression and damage to the blood collection tube.

[0041] During the blood collection process, the clamping angle can be adjusted by pulling the moving ring 58 again as needed. After blood collection is completed, the blood collection tube can be removed by sliding the moving mounting plate 46 along the limiting rod 44 and releasing the arc plate 47. If it is necessary to move the position, loosen the threaded rod 32 to lower the upright rod 2 for easy transport and placement on the platform 1.

[0042] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
