Description

Technical Field

[0001] This utility model relates to the field of cell detection auxiliary equipment technology, specifically a blood sample pretreatment device for cell detection. Background Technology

[0002] When using protein chip technology to test blood samples, the blood samples need to be fully pre-treated to ensure that the proteins in the blood are thoroughly mixed. This ensures that the proteins in the blood sample are fully mixed and remain stable during protein chip detection, thereby improving the accuracy and reliability of the experiment.

[0003] In existing technologies, blood samples are pretreated by rotating and shaking them using a motor-driven transmission mechanism. However, using an electric mechanism to shake the blood samples is costly and not economically viable. Furthermore, the motor and transmission components are prone to failure, which can affect the progress of the experiment. In addition, regular inspections and maintenance are required afterward, increasing the laboratory's operating costs.

[0004] Therefore, those skilled in the art have provided a blood sample pretreatment device for cell detection to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a blood sample pretreatment device for cell detection to solve the problems mentioned in the background art.

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

[0007] A blood sample pretreatment device for cell detection includes a fixed base, a limiting rod, a rocking base, and a transmission mechanism. The limiting rod is fixedly connected to the inner wall of one side of the fixed base, and the transmission mechanism is fixedly connected to the other side wall of the fixed base. The rocking base is fixedly connected to one side of the transmission mechanism, and the limiting rod is slidably connected to the other side of the rocking base. When the transmission mechanism rotates, it drives the rocking base to rotate and reciprocate laterally.

[0008] As a further embodiment of this utility model: the transmission mechanism includes a fixed connecting rod, a driven gear, a partial gear, a torsion spring, a reciprocating threaded screw, a limiting convex ring, and a manual wheel. The reciprocating threaded screw passes through one side of the threaded connection to the fixed base. Two sets of fixed connecting rods are fixedly connected to one side of the rocking base near the reciprocating threaded screw. One set of fixed connecting rods is fixedly connected to a driven gear on one side, and the other set of fixed connecting rods is rotatably connected to a partial gear on one side. The other side of the partial gear is fixedly connected to one side of the reciprocating threaded screw. A manual wheel is fixedly connected to the other side of the reciprocating threaded screw. A limiting convex ring is fixedly connected to the outer side of the reciprocating threaded screw.

[0009] As a further embodiment of this utility model: a limiting plate is fixedly connected between the inner sidewalls of the rocking base, and a limiting cover plate is rotatably connected to one side of the upper end of the rocking base.

[0010] As a further improvement of this utility model: the rocking base and the limiting cover are fixedly connected to the two ends on one side, and a threaded rod is threadedly connected between the two sets of limiting blocks that are close to each other.

[0011] As a further improvement of this utility model, multiple sets of limiting rubber blocks are fixedly connected to the lower side of the limiting cover plate.

[0012] As a further improvement of this utility model, multiple sets of test tube slots are provided on the inner side of the rocking base and the limiting plate.

[0013] As a further improvement of this utility model, the partial gear and the driven gear are meshed with each other.

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

[0015] 1. Compared with the prior art that uses an electric mechanism to shake blood samples, the device of this utility model adopts a manual drive method, which significantly reduces costs. It does not have a complex electric system, thus reducing the risk of failure of motor and transmission components and avoiding maintenance costs.

[0016] 2. This utility model uses a manual wheel-driven reciprocating screw for shaking and lateral movement, which is relatively simple and does not require power support. This makes it convenient for laboratory personnel to operate in environments without power. The shaking base can not only rotate, but also move the blood sample tube laterally during the reciprocating sliding process. This combined movement method can ensure that the blood sample is fully mixed, improve the uniformity of blood sample pretreatment, and thus improve the accuracy of subsequent protein chip detection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Reference Figure 1 , 2 4. This embodiment provides a blood sample pretreatment device for cell detection, including a fixed base 1, a limiting rod 2, a shaking base 3, and a transmission mechanism 4. The limiting rod 2 is fixedly connected to the inner wall of one side of the fixed base 1, and the transmission mechanism 4 is fixedly connected to the other side wall of the fixed base 1. The shaking base 3 is fixedly connected to one side of the transmission mechanism 4. The limiting rod 2 is slidably connected to the other side of the shaking base 3. When the transmission mechanism 4 rotates, it is used to drive the shaking base 3 to rotate and reciprocate laterally. The inner walls of the shaking base 3 are fixedly connected to a limiting plate 5. The upper end of the shaking base 3 is rotatably connected to a limiting cover plate 6. The shaking base 3 and the limiting cover plate 6 are fixedly connected to both ends of one side near the two ends. The two sets of limiting blocks 8 that are close to each other are threadedly connected to a threaded rod 9. The lower side of the limiting cover plate 6 is fixedly connected to multiple sets of limiting rubber blocks 7. Multiple sets of test tube slots 10 are opened on the inner side of the shaking base 3 and the limiting plate 5.

[0025] When using this utility model, the staff first needs to put the blood sample into the test tube, then rotate the threaded rod 9 between the shaking base 3 and the limiting block 8 on one side of the limiting cover plate 6, rotate and remove the threaded rod 9, loosen the shaking base 3 and the limiting cover plate 6, insert the test tube containing the blood sample into the test tube slot 10 opened in the limiting plate 5 and the shaking base 3, and then cover the limiting cover plate 6, so that the limiting rubber block 7 at the lower end of the limiting cover plate 6 is stuck at the mouth of the blood sample test tube for limiting. Rotate the threaded rod 9 through the limiting blocks 8 on both sides of the shaking base 3 and the limiting cover plate 6 that are close to each other, so that the threaded rod 9 limits and fixes the shaking base 3 and the limiting cover plate 6, so that the blood sample test tube is limited and fixed in the shaking base 3.

[0026] It should be noted that both the shaker base 3 and the inner side of the limiting plate 5 have sponge pads in the test tube slots 10 to protect the blood sample tubes and prevent them from breaking.

[0027] Example 2

[0028] Reference Figure 1 , 2 3. This embodiment is based on the previous embodiment, but differs in that the transmission mechanism 4 includes a fixed connecting rod 41, a driven gear 42, a partial gear 43, a torsion spring 44, a reciprocating threaded screw 45, a limiting convex ring 46, and a manual wheel 47. The reciprocating threaded screw 45 passes through one side of the threaded fixed base 1. Two sets of fixed connecting rods 41 are fixedly connected to one side of the rocking base 3 near the reciprocating threaded screw 45. One set of fixed connecting rods 41 is fixedly connected to the driven gear 42 on one side, and the other set of fixed connecting rods 41 is rotatably connected to the partial gear 43 on one side. The other side of the partial gear 43 is fixedly connected to one side of the reciprocating threaded screw 45. The other side of the reciprocating threaded screw 45 is fixedly connected to the manual wheel 47. The outer side of the reciprocating threaded screw 45 is fixedly connected to the limiting convex ring 46. The partial gear 43 and the driven gear 42 are meshed with each other.

[0029] After the blood sample tube is fixed in place within the shaking base 3 and the limiting cover 6, when it is necessary to shake the blood sample in the blood sample tube evenly, the operator rotates the manual wheel 47. The manual wheel 47 drives the reciprocating threaded screw 45 to rotate, which in turn drives a portion of the gear 43 to rotate. The portion of the gear 43 drives the driven gear 42 to rotate, and the driven gear 42 drives the shaking base 3 to rotate to the preset angle. When the portion of the gear 43 and the driven gear 42 are no longer engaged, the shaking base 3 will rotate back to its original position under the action of gravity. After the shaking base 3 has rotated back to its original position, the portion of the gear 43 and the driven gear 42 will re-engage, and the portion of the gear 43 will drive the driven gear 42 to rotate again. The driven gear 42 will then drive the shaking base 3 to rotate. At the same time, the reciprocating threaded screw 45 drives the shaking base 3 to slide back and forth on the limiting rod 2, so that the shaking base 3 moves laterally while shaking, ensuring that the blood sample in the shaking base 3 is thoroughly mixed.
