Description

Technical Field

[0001] This utility model belongs to the field of medical technology, specifically a blood collection tube fixing device. Background Technology

[0002] In the modern medical system, blood collection is a crucial link in disease diagnosis, health monitoring, and scientific research analysis. The standardization and stability of blood collection have a decisive impact on the accuracy of subsequent test results. As a basic piece of equipment to ensure the smooth progress of the blood collection process, the performance of blood collection tube fixation devices directly affects the safety and effectiveness of medical operations. However, the mainstream blood collection tube fixation devices currently on the market have revealed many problems that urgently need to be solved in practical applications.

[0003] Traditional desktop holders, such as multi-slot holders and rotating holders, while achieving some degree of orderly placement of blood collection tubes, offer less than ideal stability. Multi-slot holders typically employ simple slot designs, limiting only the horizontal displacement of the blood collection tubes but failing to effectively constrain their vertical movement. During blood collection, frequent handling by medical staff easily generates vibrations, causing the blood collection tubes to shake up and down within the slots. This not only increases the difficulty of blood collection but may also lead to blood sample stratification, hemolysis, and other phenomena, severely impacting the reliability of test data. While rotating holders facilitate quick selection of blood collection tubes, their rotating structure lacks a stable braking mechanism. During rotation, the blood collection tubes are prone to tilting, slipping, or even spilling due to centrifugal force, posing a risk of cross-contamination and endangering the safety of medical staff and the cleanliness of the laboratory environment.

[0004] Furthermore, in the clinical blood collection and sample transportation process, the existing fixation devices are unable to cope with the complex and ever-changing environmental challenges. Hospitals have a fast pace of daily work and high staff turnover, and blood collection areas are often crowded, making the fixation devices extremely susceptible to external impacts. During sample transportation, the bumps and vibrations generated by vehicle movement also affect the fixation effect of blood collection tubes. The existing fixation devices lack effective anti-tipping designs and cannot provide a stable preservation environment for blood samples, which greatly increases the probability of sample damage during transportation, thereby delaying diagnosis and affecting the patient's treatment process.

[0005] Therefore, a blood collection tube fixing device is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a blood collection tube fixing device. It uses a dual fixing structure of squeezing component and pressure fixing component to ensure the stability of the blood collection tube, and a counterweight component is provided to enhance the anti-tipping performance of the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a blood collection tube fixing device, comprising a base, a column fixedly connected to the center of the top of the base, a rotating plate rotatably connected to the column, a fixing ear plate fixedly fixed to the outer side of the rotating plate, a bottom groove seat provided on the fixing ear plate, two symmetrically arranged arc-shaped plates fixedly connected to the top of the bottom groove seat, a guide ring fixedly connected to the top of the arc-shaped plates, a squeezing component provided on one of the arc-shaped plates, a blood collection tube provided inside the guide ring, the bottom end of the blood collection tube being located on the bottom groove seat, a pressure fixing component provided on the rotating plate at a position corresponding to the blood collection tube, and a counterweight component installed on the base.

[0011] Preferably, the clamping assembly includes a stand that is fixedly connected to the rotating plate, a crossbar connected to the top of the stand via a pivot, the end of the crossbar pressing against the top of the blood collection tube, a first pivot installed in the middle of the crossbar, a spring telescopic rod connected to the first pivot, a second pivot connected to the end of the spring telescopic rod, and the second pivot positioned at a suitable location on the stand.

[0012] Preferably, the spring telescopic rod includes a hollow rod, a movable block is provided inside the hollow rod, a tension rod is fixedly connected to the movable block, a compression spring is sleeved on the tension rod inside the hollow rod, and the end of the tension rod away from the movable block passes through the hollow rod.

[0013] Preferably, the counterweight assembly includes a groove formed at the bottom of the base, a counterweight plate arranged vertically in the groove, a guide hole formed on the counterweight plate, a guide rod arranged in the guide hole, the top end of the guide rod being fixedly connected to the base, and a threaded positioning sleeve arranged below the lowest counterweight plate, the threaded positioning sleeve being threadedly connected to the guide rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up a squeezing component, the blood collection tube can be initially fixed during blood collection to prevent vertical displacement during the blood collection process. After blood collection, the pressure-fixing component is pressed against the top of the blood collection tube to further fix the blood collection tube and improve the stability of the blood collection tube on the device.

[0016] 2. By setting up a counterweight component, this utility model gives the device flexible stability adjustment capabilities.

A movable rod 84 is fixedly connected to the center of the movable plate 83. A squeezing plate 85 is fixedly connected to the end of the movable rod 84 near the arc-shaped plate 6 through the U-shaped frame 81. A through groove 86 is opened on the arc-shaped plate 6 at the position corresponding to the squeezing plate 85. A pulling block 87 is connected to the end of the movable plate 83 away from the arc-shaped plate 6 through the cylinder 82. A squeezing spring 88 is connected to the side of the movable plate 83 near the pulling block 87. The squeezing spring 88 is sleeved on the movable rod 84 inside the cylinder 82. During blood collection, the squeezing assembly 8 can initially fix the blood collection tube 9 to prevent vertical displacement during the blood collection process.

[0035] It is worth noting that the clamping assembly 10 includes a stand 101 that is fixedly connected to the rotating plate 3. The top of the stand 101 is connected to a crossbar 102 via a pivot. The end of the crossbar 102 presses against the top of the blood collection tube 9. A first pivot 103 is installed in the middle of the crossbar 102. The first pivot 103 is connected to a spring telescopic rod 104. The end of the spring telescopic rod 104 is connected to a second pivot 105. The second pivot 105 is located at a suitable position on the stand 101. After blood collection, the clamping assembly 10 presses against the top of the blood collection tube 9 to further fix the blood collection tube 9 and improve the stability of the blood collection tube 9 on the device.
