Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and in particular relates to a blood separation device for blood testing. Background Art

[0002] Blood testing is a key means of assessing health status and diagnosing diseases. It provides important information about individual physiological status, disease risk and treatment by analyzing blood components. In this process, blood separation devices play a key role, which can effectively separate blood for further analysis and testing.

[0003] After searching, it was found that, for example, the Chinese patent No. CN220048537U is a separation device for blood test analysis, which can clamp test tubes of different sizes by using a micro electric push rod and a clamping plate, so that the test tubes of too small size will not fly out of the placement slot during rotation, and through the use of a fixing rod and a fixing slot, the matching clamping plate can be replaced according to the clamping needs, thereby improving the clamping effect;

[0004] However, the above device has certain limitations when performing blood separation in multiple test tubes. Usually, it is necessary to place a test tube first and wait for it to be clamped and fixed before the next test tube can be placed. This process of placing one test tube at a time is cumbersome and time-consuming, especially when processing multiple test tubes in batches. If a method of placing multiple test tubes at one time and then clamping them is adopted, although the operation speed can be increased, it may cause the previous test tube to tilt or fall off when the next test tube is placed if it is not fixed, which increases the inconvenience and potential risks of operation.

[0022] The above-mentioned separation device body, mounting slot, motor, turntable, heat dissipation hole and placement seat 1 are all existing mature technologies and are disclosed in the announcement number CN220048537U, a separation device for blood detection and analysis in China.

The rotating placement seat 1 will drive the test tube to rotate at a high speed, thereby completing the separation of blood. It will not be described in detail in this embodiment. The core solution of this technical solution lies in the specific structure of the placement mechanism;

[0023] The placement seat 1 is provided with a working slot and a plurality of placement slots, the working slot is located in the middle of the placement seat 1, and the plurality of placement slots are arranged in a circular array on the outside of the working slot;

[0027] A second arc-shaped clamping plate 11 is fixed to one end of the rectangular rod 6 away from the guide rod 10, and multiple second arc-shaped clamping plates 11 are respectively located on the inner sides of multiple placement grooves on the placement seat 1, an elastic plate 12 is fixed to one end of the second arc-shaped clamping plate 11, and a first arc-shaped clamping plate 2 is also fixed to the inner side of the placement groove on the placement seat 1.

[0028] See attached Figure 1 -Attached Figure 3 The placement mechanism also includes a pre-clamping assembly having the same number as the second arc-shaped clamping plate 11, each pre-clamping assembly includes two rectangular square bars 13, and two limiting grooves adapted to the rectangular square bars 13 are arranged inside the placement seat 1 and between each placement groove and the working groove. The two rectangular square bars 13 are respectively located on the inner sides of the two limiting grooves, one end of the rectangular square bar 13 is located in the placement groove, the other end of the rectangular square bar 13 is located in the working groove, and one of the rectangular square bars 13 is located above the top of the second arc-shaped clamping plate 11, and the other rectangular square bar 13 is located below the bottom of the second arc-shaped clamping plate 11, one end of the rectangular square bar 13 is located in the placement groove and a third arc-shaped clamping plate 16 is fixed, the other end of the rectangular square bar 13 is located in the working groove and a rectangular plate 14 is fixed, and the height of the rectangular plate 14 is slightly higher than the height of the rectangular square bar 13;

[0029] See attached Figure 2 and attached Figure 3A spring 15 is provided on the outside of the rectangular strip 13 and located on the outside of the third arc-shaped clamping plate 16 away from the first arc-shaped clamping plate 2 and on the inside of the placement groove on the placement seat 1. One end of the spring 15 abuts against or is fixed to the third arc-shaped clamping plate 16, and the other end of the spring 15 abuts against or is fixed to the inner wall of the placement groove on the placement seat 1.

[0030] See attached Figure 3 and attached Figure 4 , the side of the third arc-shaped clamping plate 16, the second arc-shaped clamping plate 11 and the elastic plate 12 bent inwardly faces the first arc-shaped clamping plate 2, and the side of the first arc-shaped clamping plate 2 bent inwardly faces the third arc-shaped clamping plate 16, the second arc-shaped clamping plate 11 and the elastic plate 12, and the height of the second arc-shaped clamping plate 11 is set to be slightly lower than the distance between the two third arc-shaped clamping plates 16, and the heights of the two third arc-shaped clamping plates 16 correspond to the top and bottom of the first arc-shaped clamping plate 2 respectively;

[0031] In addition, the first arc-shaped clamping plate 2 and the third arc-shaped clamping plate 16 are both made of elastic materials such as silicone and latex. Thus, the first arc-shaped clamping plate 2 and the third arc-shaped clamping plate 16 can adapt to test tubes of different shapes and sizes. Not only does it increase the friction between the test tube and the clamping plate, but more importantly, it improves the clamping effect and ensures that the test tube is firmly fixed.

[0032] According to the above structure, when blood is separated, one or more test tubes are respectively inserted between the first arc-shaped clamping plate 2 and the third arc-shaped clamping plate 16 in the plurality of placement grooves. During the process, the bottom of the test tube is in contact with the third arc-shaped clamping plate 16 in advance, and the third arc-shaped clamping plate 16 and the rectangular square bar 13 are forced to move toward the side away from the first arc-shaped clamping plate 2. At this time, the spring 15 is forced to contract. When the test tube is inserted, the elastic characteristics of the spring 15 can make the third arc-shaped clamping plate 16 close to the outside of the test tube, so that the test tube can be pre-clamped between the first arc-shaped clamping plate 2 and the third arc-shaped clamping plate 16.

[0033] Then, the electric push rod 3 is started to operate, and the operation of the electric push rod 3 enables the mounting seat 4 to move upward. At this time, the rectangular rod 6 can be moved toward the test tube and the first arc-shaped clamping plate 2 through the restriction of the connecting rod 5 and the guide rod 10, so that the second arc-shaped clamping plate 11 and the elastic plate 12 can move toward the test tube and the first arc-shaped clamping plate 2, and the elastic plate 12 can be against the test tube and deformed to wrap around the outside of the test tube, so that the test tube can be stably clamped between the first arc-shaped clamping plate 2 and the third arc-shaped clamping plate 16, and through the elastic characteristics of the elastic plate 12, not only can test tubes of different diameters be clamped and fixed, but also test tubes of various shapes and curvatures can be flexibly adapted, thereby improving the adaptability of the device.

[0034] After the blood separation is completed, the electric push rod 3 is started to reset the second arc-shaped clamping plate 11 and the elastic plate 12. At this time, the test tube can be easily removed. The elastic characteristics of the spring 15 and the limiting effect of the rectangular plate 14 can reset the third arc-shaped clamping plate 16.

[0035] In summary, when fixing the test tube, the utility model can perform pre-clamping and secondary clamping on the test tube;

[0036] In the scenario of multi-tube blood separation, pre-clamping ensures that each test tube is fixed and supported in time when placed. It avoids the tilting and falling of the previous test tube when the next test tube is placed, giving the operator greater operational freedom and concentration. More importantly, it eliminates the need for the operator to provide additional manual support or find external tools to temporarily fix the last placed test tube, improving the safety, fluency and efficiency of the operation, making the entire process more convenient and reliable.

[0037] Secondly, through the secondary clamping fixation, this device further improves the clamping effect, effectively reduces the movement of the test tube during the blood separation process, and ensures the stability of the test tube position. This double clamping design effectively prevents accidental displacement or shaking of the test tube.

[0038] In addition, the utility model only needs one electric push rod 3 to clamp and fix multiple test tubes. This design has obvious advantages in energy consumption and cost control. Compared with most existing devices that generally need to use multiple components similar to the electric push rod 3 to fix multiple test tubes, the utility model reduces the energy required for multiple push rods to operate simultaneously, thereby reducing energy waste. At the same time, only one electric push rod 3 is needed to simplify the composition and operation of the device, making it easier to maintain and manage.

[0039] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
