Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a test tube holder for testing cards related to blood transfusion. Background Technology

[0002] Commercially available test strips (microcolumn gel method) are now widely used for transfusion-related tests (such as blood typing and antiglobulin testing). Small and medium-sized medical institutions' laboratories or transfusion departments can choose manual methods for testing when the sample volume is small. Proper placement of test tubes and commercially available test strips during the testing process is crucial for optimizing complex testing procedures and preventing errors.

[0003] Chinese patent CN202222785580.2 discloses a blood collection rack, including a base plate, a fixed plate, and a lifting plate. Baffles are installed at both ends of the base plate, and fixed plates are symmetrically installed between the two baffles. Several positioning holes are evenly distributed inside the fixed plates. A fixed block is installed on the left end of the left baffle, a lifting groove is formed on the right end of the fixed block, and a sliding groove is formed on the left end of the fixed block, connecting to the lifting groove. A fixed rod is installed inside the lifting groove, and a lifting block is fitted onto the outer surface of the fixed rod. A bolt is rotatably connected to the left end of the lifting block, passing through the sliding groove. A clamping plate is fitted onto the outer surface of the bolt, and the clamping plate and bolt are threadedly connected. This invention allows the lifting plate to rise above the blood collection tube, and by pulling the baffle to the right and placing it at the center of the through hole, the lifting plate can be lowered so that the baffle is positioned above the blood collection tube. This prevents the blood collection tube from shaking during transport. Simultaneously, when the blood collection rack falls, the baffle and base plate protect the blood collection tube, preventing it from detaching and breaking.

[0004] Regarding the aforementioned technologies, the positioning holes on the blood collection rack are not suitable for test tubes of different sizes, and when medical staff use test cards to test specimens on the test tube rack, the test cards cannot be placed in accordance with the specimens, which can easily lead to confusion; moreover, when the temperature is too low in winter, the condensation phenomenon of the specimens on the blood collection rack can lead to incorrect test results. Utility Model Content

[0005] The purpose of this invention is to provide a test tube holder for transfusion-related test cards, aiming to solve the problems of traditional test tube holders having poor applicability, easily confusing test results, and causing condensation of specimens in low winter temperatures, which can lead to incorrect test results.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A test tube holder for transfusion-related test cards includes a mounting frame and an upper fixing plate and a lower fixing plate horizontally disposed within the mounting frame. Each of the upper and lower fixing plates has a plurality of test tube holes evenly distributed on one side. The other side of the upper fixing plate has a plurality of test card slots. The lower end face of the lower fixing plate is fixedly connected to an L-shaped bracket for supporting the bottom of the test tubes, corresponding to each test tube hole. A fixing component for fixing test tubes of different sizes is disposed between two adjacent test tube holes on the upper end face of the lower fixing plate. An incubation temperature control device is disposed below the mounting frame.

[0008] In one alternative: the fixing assembly includes a column disposed on the lower fixing plate, and the column is provided with a snap ring for fixing two adjacent test tubes in the test tube holes.

[0009] In one alternative: the column has a square cross-section, the column is fitted with a mounting sleeve, and the retaining spring is fixed to the mounting sleeve.

[0010] In one alternative: a wedge is fixed to the upper end face of the snap ring, and a rubber layer is provided on the outer surface of the snap ring.

[0011] In one alternative: the upper fixing plate has letters or numbers marking the test tube holes and the test card slots.

[0012] In one alternative: the incubation temperature control device is a water bath, the water bath is equipped with a temperature control switch, the water bath has a support platform, and the mounting frame is inserted into the water bath and abuts against the support platform.

[0013] In one alternative: a partition is provided between the test tube hole and the test card slot, the partition extending from the lower fixed plate to the upper fixed plate.

[0014] In one alternative embodiment, both the upper fixing plate and the lower fixing plate are transparent.

[0015] The advantages of this utility model compared to the prior art are:

[0016] This invention utilizes a fixing component to maintain a stable state between the specimen and the test tube rack, preventing accidents during transport and allowing the rack to accommodate test tubes of different sizes. Simultaneously, test cards are placed in their corresponding slots, facilitating access for medical personnel and reducing the likelihood of mixed test results.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0023] Example 1:

[0024] like Figures 1-4As shown, this utility model provides a test tube rack for blood transfusion-related test cards. It includes a mounting frame 1 and an upper fixing plate 2 and a lower fixing plate 3 horizontally arranged within the mounting frame 1. A plurality of test tube holes 21 are evenly opened on one side of the upper fixing plate 2 and the lower fixing plate 3. A plurality of test card slots 22 are opened on the other side of the upper fixing plate 2. An L-shaped bracket 31 for supporting the bottom of the test tube is fixedly connected to the lower end face of the lower fixing plate 3 corresponding to the test tube holes 21. A fixing component for fixing test tubes of different sizes is provided between two adjacent test tube holes 21 on the upper end face of the lower fixing plate 3. An incubation temperature control device is provided below the mounting frame 1.

[0025] After medical staff use the test card to test the specimen, they place the specimen in the test tube well 21. The fixing component keeps the specimen and test tube rack stable, preventing accidents during transport and allowing the rack to accommodate test tubes of different sizes. Simultaneously, the test card is placed in the corresponding test card slot 22, facilitating medical staff and reducing the likelihood of confused test results. Furthermore, the incubation temperature control device below the mounting frame 1 keeps the specimen warm in low temperatures, preventing condensation and thus avoiding incorrect test results. This effectively solves the problems of traditional test tube racks' limited applicability, easy result confusion, and condensation leading to incorrect results in low winter temperatures.

[0026] Specifically, the fixing assembly includes a column 32 mounted on the lower fixing plate 3. The column 32 is equipped with locking spring clips 34 for securing test tubes in adjacent test tube holes 21. The locking spring clips 34 are designed with a certain degree of elasticity to accommodate test tubes of different diameters, and securely fix the test tubes in the test tube holes 21 through a locking action, thereby ensuring the accuracy and safety of the test. Furthermore, the compact design of the column 32 and locking spring clips 34 allows the test tube rack to make full use of space, enabling multiple test tubes to be arranged closely and orderly, making the testing process neater and more organized.

[0027] Furthermore, the column 32 has a square cross-section, and an mounting sleeve 33 is provided around the column 32, on which the retaining spring 34 is fixedly connected. The design of the mounting sleeve 33 makes it easier to fix the retaining spring 34 to the mounting sleeve 33, without having to fix it directly to the column 32, thus simplifying the installation process; at the same time, it makes it easier to disassemble, replace and clean the retaining spring 34, improving the versatility and practicality of the test tube rack.

[0028] Furthermore, a wedge (not shown in the figure) is fixed to the upper end face of the retaining spring 34, allowing the test tube to slide more easily over the retaining spring 34 when inserted into the test tube hole 21, reducing resistance during insertion. Simultaneously, the guiding effect of the wedge allows the test tube to gradually adapt to the pressure of the retaining spring 34 during insertion, preventing damage to the test tube due to sudden force. In addition, a rubber layer 341 is provided on the outer surface of the retaining spring 34. The rubber layer 341 has a high coefficient of friction, increasing the friction between the retaining spring 34 and the side wall of the test tube, thereby improving the stability and reliability of the fixation. At the same time, the rubber layer 341 acts as a buffer layer, reducing direct friction and wear between the retaining spring 34 and the test tube surface, thus extending the service life of the test tube.

[0029] Meanwhile, the upper fixing plate 2 has letter or number markings in front of the empty spaces of the test tube hole 21 and the test card slot 22, which enables medical staff to quickly and accurately identify and locate the specific test tube hole 21 or test card slot 22 without spending extra time searching one by one; it also reduces problems such as confusion or misplacement of test tubes or test cards due to human negligence, and improves the accuracy and reliability of the experiment.

[0030] Example 2:

[0031] like Figures 1-4 As shown, the difference between this embodiment and Embodiment 1 is that:

[0032] The incubation temperature control device is a water bath 4, which is equipped with a temperature control switch. A support 41 is installed inside the water bath 4, and the mounting frame 1 is inserted into the water bath 4 and abuts against the support 41. This allows medical personnel to adjust the temperature control switch to set the desired water bath temperature when it is too low, ensuring that the water bath 4 remains stable after reaching the set temperature. This prevents condensation of specimens on the test tube rack, which could lead to incorrect test results.

[0033] Furthermore, a partition 5 is provided between the test tube hole 21 and the test card slot 22. The partition 5 extends from the lower fixed plate 3 to the upper fixed plate 2. The design of the partition 5 prevents water vapor in the water bath 4 from flowing into the test card placement area when the weather is cold, thus affecting the test results. At the same time, it also prevents direct contact between the test tube and the test card, reducing the risk of cross-contamination, thereby improving the accuracy and reliability of the experiment.

[0034] Furthermore, both the upper fixing plate 2 and the lower fixing plate 3 are transparent, specifically made of transparent plastic sheets, acrylic sheets, etc. This allows medical staff to directly observe the testing status within the test tube well 21 and the test card slot 22, facilitating real-time monitoring of the testing process and timely detection and handling of any potential abnormalities or errors.

[0035] The specific working effects of this utility model are as follows:

[0036] When using the device, medical staff test the specimen using the test card and then place the specimen in the test tube well 21. The fixing components stabilize the specimen and the test tube rack, preventing accidents during transport and allowing the rack to accommodate test tubes of different sizes. Simultaneously, the test card is placed in the corresponding test card slot 22, facilitating medical staff and reducing the likelihood of mixed test results. Furthermore, the incubation temperature control device below the mounting frame 1 keeps the specimen warm in low temperatures, preventing condensation and thus avoiding incorrect test results. This effectively solves the problems of traditional test tube racks' limited applicability, easy result confusion, and condensation leading to incorrect results in low winter temperatures.
