Abstract
Description
Technical Field
[0001] This application relates to the field of fixation technology, and more particularly to a blood sample tube fixation device with a sorting function. Background Technology
[0002] In medical testing, laboratory research, and clinical diagnosis, the collection, storage, and processing of blood samples are crucial. Blood tubes, as the primary containers for blood samples, typically need to be arranged, secured, and labeled in an orderly manner during experiments to ensure accurate and efficient sample management. Traditional blood tube holders are mostly simple support or tray structures with limited functionality, providing only basic placement and failing to meet the demands of modern laboratories for sample sorting, classification, and rapid access.
[0003] Currently, common blood sample tube holders on the market have the following technical problems: 1. Traditional holders usually use a fixed number of holes or slots. If the samples are not marked or numbered after the staff takes them, it is easy to cause the sample and sample information to be mismatched; 2. Traditional holders are generally placed flat. When the staff takes the blood sample tubes, their hands are likely to come into contact with the top of other sample tubes, which makes it easy for blood sample tubes to generate cross-infection risk. Utility Model Content
[0004] This utility model provides a blood sample tube holder with a sorting function. The blood sample tube holder is convenient for sampling and realizes sampling in sequence, which will not cause accidental sampling and realizes the accuracy of sampling work.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A blood sample tube holder with sorting function includes a base plate, a load-bearing plate, and an angle adjustment device;
[0007] The base plate and the load-bearing plate are rotatably connected; the angle adjustment device includes an upper top plate, a lower top plate and a screw, the upper top plate is fixed to the side end of the load-bearing plate, the lower top plate is fixed to the side end of the base plate, the lower top plate is provided with a threaded groove adapted for the screw to pass through, and the upper end of the screw contacts the upper top plate; the load-bearing plate is provided with an outer baffle and an inner baffle, and a channel adapted for the insertion of a blood sample tube is formed between the outer baffle and the inner baffle.
[0008] Preferably, the lower end of the screw is provided with a rotating handle.
[0009] Preferably, the upper end of the base plate is provided with a rotating block, and the load-bearing plate is provided with a rotating groove adapted to the insertion of the rotating block.
[0010] Preferably, the outer baffle has arc-shaped baffles at both ends.
[0011] Preferably, the angle adjustment device further includes a push tube assembly, which includes a push rod and a spring. Both the outer baffle and the inner baffle are provided with through slots that allow the push rod to pass through. The inner baffle is provided with a fixing plate. One end of the spring is fixed to the fixing plate, and the other end is fixed to the push rod.
[0012] Preferably, push blocks are provided at both ends of the push rod.
[0013] Preferably, the push rod is provided with a fixing block, and the end of the spring facing away from the fixing plate is fixed to the fixing block.
[0014] Compared with the prior art, the advantages or beneficial effects of the technical solution of this application include:
[0015] 1. By adjusting the angle of the sampling tube, the blood sample tube moves to the sampling port according to its own gravity, and only one blood sample tube is allowed to pass through at a time, which greatly ensures the accuracy of blood sample collection and testing, and avoids problems such as mistaking, missing or disordered order.
[0016] 2. Adjust the tilt angle of the support plate according to the different specifications of blood sample tubes so that the blood sample tubes of different specifications can slide down on their own, so as to meet the requirements of the test personnel to collect samples again.
[0017] 3. Using a single blood sample tube for each sample avoids contact between the technician's hands and the openings of other blood sample tubes, reducing the risk of cross-contamination and thus further improving the accuracy of blood sample testing. Attached Figure Description

[0022] The following detailed description of the embodiments of this application, in conjunction with the accompanying drawings, will provide a thorough understanding of how this application uses technical means to solve technical problems and achieve corresponding technical effects, enabling its implementation. The embodiments of this application and the various features within them can be combined with each other without conflict, and all resulting technical solutions are within the protection scope of this application.
[0023] It should be clearly stated that the embodiments described below are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0024] Example 1: This example provides a detailed explanation of the blood sample tube holder design:
[0025] A blood sample tube holder with sorting function includes a base plate 5, a load-bearing plate, and an angle adjustment device;
[0026] The base plate 5 and the load-bearing plate are rotatably connected. The angle adjustment device includes an upper top plate 8, a lower top plate 7, and a screw 9. The upper top plate 8 is fixed to the side end of the load-bearing plate, and the lower top plate 7 is fixed to the side end of the base plate 5. The lower top plate 7 has a threaded groove for the screw 9 to pass through, and the upper end of the screw 9 contacts the upper top plate 8. The load-bearing plate has an outer baffle 2 and an inner baffle 12, and a channel for inserting a blood sample tube 11 is formed between the outer baffle 2 and the inner baffle 12. The lower end of the screw 9 has a rotating handle 10. The upper end of the base plate 5 has a rotating block 1, and the load-bearing plate has a rotating groove for the rotating block 1 to be embedded in.
[0027] Among them, such as Figure 1 and Figure 2 As shown, the angle between the base plate 5 and the load-bearing plate is adjustable. Specifically, it can be adjusted according to the specifications of the blood sample tube, allowing the blood sample tube to slide down the channel on its own. The specific operation for adjusting the load-bearing plate is as follows:
[0028] Rotate the rotating handle 10 so that the screw 9 rotates in the threaded groove of the lower top plate 7, thereby slowly lifting the upper top plate 8 upward, allowing at least the blood sample tubes pre-arranged in the channel to slide down freely.
[0029] like Figure 2 As shown, the outer baffle 2 has arc-shaped baffles at both ends. Since the blood sample tube 11 is drawn upwards by the staff, the function of the arc-shaped baffles is to prevent the blood sample tube 11 from sliding out along the end of the channel.
[0030] like Figure 1As shown, the angle adjustment device also includes a push tube assembly, which includes a push rod 4 and a spring 16. Both the outer baffle 2 and the inner baffle 12 are provided with through slots 6 that are adapted to allow the push rod 4 to pass through. The inner baffle 12 is provided with a fixing plate. One end of the spring 16 is fixed to the fixing plate, and the other end is fixed to the push rod 4.
[0031] The purpose of the push tube assembly is to drive the blood sample tube at the top of the channel downward. It relies on the thrust of the spring 16 when it deforms to push the push rod 4 downward, thereby driving the blood sample tubes 11 arranged in the channel to move downward.
[0032] like Figure 2 As shown, push blocks 3 are provided at both ends of the push rod 4. The function of the push blocks 3 is to facilitate the application of force by the staff. If it is necessary to re-insert the blood sample tube, the push blocks 3 can be used to push the push rod 4 upward to the top until the blood sample tube 11 is inserted, then the staff can release the handle. At this time, the push rod 4 will contact the blood sample tube 11 and push it to the arc-shaped blocking part.
[0033] In this embodiment, the push rod 4 is provided with a fixing block 14, and the spring 16 is fixed to the fixing block 14 at the end facing away from the fixing plate.
[0034] Example 2: Batch blood sample testing in clinical laboratory
[0035] Scenario Description: In the laboratory of a large hospital, hundreds of blood sample tubes (such as those for biochemical and immunological tests) need to be processed daily. Traditional fixation racks require manual handling of each sample, which can easily lead to sample order disorder or missed detection due to operator fatigue.
[0036] Applications of this mounting bracket:
[0037] Sequential sliding sampling: Arrange blood sample tubes in the channel according to testing priority, and adjust the tilt angle of the support plate (e.g., 15°) so that the blood sample tubes automatically slide to the arc-shaped barrier due to gravity. The test personnel can only draw blood from the bottom blood sample tube at a time to avoid accidentally taking adjacent samples.
[0038] Preventing cross-contamination: The tilted design ensures that hands only touch the top of the target blood sample tube, avoiding contact with other tube openings and reducing the risk of cross-infection.
[0039] Quick reset: The push rod assembly automatically pushes down the remaining blood sample tube after sampling, eliminating the need for manual adjustment and improving batch testing efficiency.
[0040] Results: The detection error rate was reduced by 60%, and the processing time for a single batch of samples was shortened by 30%.
[0041] Example 3: Emergency Blood Sample Sorting in the Emergency Department
[0042] Scenario description: The emergency department needs to quickly process blood sample tubes of various sizes (such as 5ml coagulation tubes and 2ml blood routine tubes), and in emergency situations, it is easy to grab the wrong sample due to panic.
[0043] Applications of this mounting bracket:
[0044] Multi-size compatibility: The angle of the load-bearing plate can be adjusted by screw (e.g., 20° for 5ml tubes, 10° for 2ml tubes) to ensure that blood sample tubes of different sizes can slide down smoothly.
[0045] One-button reset: The push block design at the top of the push rod makes it easy for nurses to operate with one hand, and can quickly push the push rod up to free up space in the channel when refilling samples in an emergency.
[0046] Accidental contact protection: The arc-shaped barrier prevents the blood sample tube from accidentally slipping out during handling, ensuring safe transport.
[0047] Results: The accuracy of emergency sample sorting increased to 98%, and the emergency response time was shortened by 20%.
