Description

Technical Field

[0001] The present invention belongs to the technical field of blood sample testing equipment, and more specifically, relates to a blood sample testing oscillating device. Background Art

[0002] The purpose of blood sample oscillation is mainly related to ensuring sample homogeneity, avoiding component separation or precipitation, and ensuring accurate test results. The specific functions are as follows:

[0003] Prevent stratification of blood components; promote full mixing of anticoagulants and blood; avoid hemolysis or precipitation affecting detection; ensure sample representativeness, etc.

[0004] Preventing blood stratification: Blood is composed of plasma (the liquid component) and blood cells (red blood cells, white blood cells, platelets, etc.). When left alone, blood cells gradually sink due to their greater specific gravity, causing the upper layer of plasma to separate from the lower layer of blood cells. Oscillation thoroughly mixes the blood to avoid stratification that could lead to an abnormal plasma-to-blood cell ratio, affecting the accuracy of subsequent tests (such as blood routine tests and biochemical indicators).

[0005] Promotes thorough mixing of anticoagulants and blood: In clinical testing, blood samples often require the addition of anticoagulants (such as EDTA, sodium citrate, and heparin) to prevent coagulation. Oscillation accelerates the contact between the anticoagulant and blood, ensuring even distribution of the anticoagulant and preventing localized blood coagulation that could affect test results or clog testing instruments (such as hematology analyzers).

[0006] Avoid hemolysis or precipitation that could affect testing: Vigorous shaking may cause red blood cell rupture (hemolysis), but moderate shaking can prevent red blood cell accumulation and rupture caused by prolonged standing. Certain blood components (such as lipids and proteins) may precipitate when left standing. Shaking keeps them suspended, preventing precipitation from interfering with testing (such as lipid and liver function tests).

[0007] Ensure sample representativeness: Blood tests typically analyze overall components (e.g., glucose, electrolytes). If the sample is not uniform, local test values ​​may deviate from the true level. Sampling after shaking ensures that each subsample has consistent composition and avoids biased results due to differences in sampling location (e.g., sampling the upper plasma layer or the lower blood cell layer).

[0008] For example, application number CN202210278150.3 discloses a platelet constant temperature oscillating chamber for hematology, comprising a chamber body, a temperature controller disposed at the bottom of the chamber body, and a vibration mechanism. The oscillating mechanism is disposed within the chamber body and comprises a partition fixedly connected to the chamber body, a first rotating shaft rotatably connected to the outer side of the partition body, a rotating disk disposed at the end of the first rotating shaft, a sliding sleeve disposed on the outer side of the rotating disk, the sliding sleeve slidably connected to a sliding rod, the end of the sliding rod rotatably connected to a lifting plate, a first support plate disposed in the middle of the partition body, an end of the first support plate away from the partition body rotatably connected to a third rotating shaft, an end of the third rotating shaft near the center of the device fixedly connected to one end of the rotating plate, and a first guide rod disposed at the other end of the rotating plate. The present invention is applicable to a platelet constant temperature oscillating chamber for hematology, wherein the test tubes within the chamber move in a coupled rotational and vertical motion, thereby preventing platelet deposition caused by movement in a fixed direction.

[0009] Based on the search of the above patents and in combination with the devices in the prior art, it is found that the blood sample oscillating device in the prior art is not convenient for clamping test tubes of different diameters.

[0010] Therefore, in view of this, the existing structure and defects are studied and improved, and a blood sample testing oscillation device is provided to achieve the purpose of having greater practical value. Summary of the Invention

[0042] Example 1:

[0043] As attached Figure 1 To the attached Figure 8 As shown:

[0044] The present invention provides a blood sample testing oscillating device, comprising:

[0045] A base 11 and a carrier 12 disposed on the base 11 , wherein a reciprocating drive mechanism 14 is disposed between the base 11 and the carrier 12 , and the reciprocating drive mechanism 14 is mounted on the base 11 and can drive the carrier 12 to vibrate reciprocally;

[0046] The carrier 12 is provided with a plurality of placement slots 120 , each of which has a cylinder 121 disposed therein. The cylinder 121 is provided with a buffer slot 1210 , and the buffer slot 1210 is used to place the test tube 16 ;

[0047] The pneumatic clamping mechanism 13 is provided with an air bag ring 131 . The air bag ring 131 is provided above the cylinder 121 . The air bag ring 131 can clamp the test tube 16 .

[0048] In this embodiment, an air bag ring 131 is provided, and the different inflation states of the air bag ring 131 are used to clamp test tubes 16 of different diameters. When a test tube 16 with a smaller diameter needs to be clamped, the air bag ring 131 is inflated with more gas to make it more expanded; when a test tube 16 with a larger diameter needs to be clamped, the air bag ring 131 is inflated with less gas to make it less expanded, so as to ensure that test tubes 16 within a certain diameter range can be stably placed on the carrier 12 during oscillation.

[0049] The pneumatic clamping mechanism 13 also includes a plurality of clips 132 arranged in the airbag ring 131, an air guide pipe 133 connected to the airbag ring 131, an air inlet pipe 134 connected to the air guide pipe 133 at one end, a one-way valve 135 connected to the air inlet pipe 134 at the other end, an air inlet connector 136 connected to the air inlet end of the one-way valve 135, a pressure relief valve 137 connected to the side of the air inlet pipe 134, an air outlet connector 139 connected to the air inlet connector 136, and an air pump 138 connected to the air outlet connector 139.

[0050] A plurality of clips 132 are arranged in a circular array in the airbag ring 131. When the airbag ring 131 is expanded, the clips 132 clamp the test tube 16. Since a plurality of clips 132 are arranged vertically, the test tube 16 can be stably clamped in the circumferential direction.

[0051] It should be noted that the air guide pipe 133 is used to evenly disperse the gas in each air bag ring 131. When inflating, each air bag ring 131 can be inflated synchronously. Compared with the traditional clamping mechanism, which requires clamping and fixing the test tubes one by one, it has better clamping efficiency and only requires one inflation to complete the clamping and fixation of multiple test tubes 16.

[0052] The air guide pipe 133 includes an inner ring pipe 1331 and an outer ring pipe 1332 disposed outside the inner ring pipe 1331 . Both the inner ring pipe 1331 and the outer ring pipe 1332 are connected to the air intake pipe 134 .

[0053] An outer snap ring 122 and an inner snap ring 123 are provided on the carrier 12 . The inner ring tube 1331 is clamped in the inner snap ring 123 , and the outer ring tube 1332 is clamped in the outer snap ring 122 .

[0054] A C-shaped buckle 125 is fixedly connected to the side of the carrier 12, and the air inlet connector 136 can be snapped onto the C-shaped buckle 125. The C-shaped buckle 125 is provided to fix the air inlet connector 136. After the airbag ring 131 of the pneumatic clamping mechanism 13 is fully inflated, the air inlet connector 136 and the air outlet connector 139 are disconnected and snapped onto the C-shaped buckle 125. This ensures that the reciprocating vibration of the carrier 12 does not generate any pulling force on the connection between the air inlet connector 136 and the air outlet connector 139.

[0055] The reciprocating drive mechanism 14 includes a motor 141 fixedly connected to the base 11, an eccentric wheel 142 fixedly connected to the power output shaft of the motor 141, a connecting seat 143 fixedly connected to the carrier 12, a slide rail 144 fixedly connected to the base 11, and a slider 145 slidably connected to the slide rail 144. The slider 145 is fixedly connected to the carrier 12.

[0056] An eccentric rod 1421 is fixedly connected to the outer periphery of one end surface of the eccentric wheel 142 . An oblong groove 1431 is vertically provided on the connecting seat 143 , and the eccentric rod 1421 is slidably provided in the oblong groove 1431 .

[0057] The motor 141 drives the eccentric wheel 142 to rotate, and the eccentric rod 1421 on the eccentric wheel 142 rotates and slides in the long circular groove 1431, thereby driving the connecting seat 143 to reciprocate, and the carrier 12 thereof follows the reciprocating motion.

[0058] Example 2:

[0059] The remaining features are the same as those of the first embodiment, except that the sealing member 15 is further included. The sealing member 15 includes a top plate 151, a rubber sheet 152 provided at the lower portion of the top plate 151, a guide sleeve 153 passing through and fixedly connected to the top plate 151, a screw locking member 154 fixedly connected to the carrier 12, and a nut member 155 fixedly connected to the upper portion of the carrier 12. The nut member 155 is threadedly connected to the screw locking member 154. The top plate 151 and the rubber sheet 152 are provided with a top hole 1510 for the screw locking member 154 to pass through.

[0060] The guide shaft 124 is vertically fixedly connected to the carrier 12 . The guide shaft 124 and the guide sleeve 153 are correspondingly arranged. The guide shaft 124 and the guide sleeve 153 are slidably connected.

[0061] The sealing member 15 is used to seal the upper end of the test tube 16. During use, the top plate 151 and the rubber sheet 152 are placed over the upper end of the test tube 16, with the rubber sheet 152 resting against the upper edge of the test tube 16. The guide shaft 124 is inserted into the guide sleeve 153, and the screw locking member 154 is threadedly connected to the nut 155 through the top hole 1510 provided therein, thereby locking and securing the top plate 151 and the rubber sheet 152 of the sealing member 15.

[0062] The barrel 121 is made of rubber. By providing soft rubber, a buffering effect is achieved to prevent the test tube 16 from directly colliding with the placement groove 120 and causing damage to the test tube 16.

[0063] Example 3:

[0064] The remaining features are the same as those of Example 1, with the difference being that the barrel 121 in this embodiment is made of sponge. Sponge inherently has a large number of interconnected or closed pores, resulting in a soft, elastic, and comfortable touch. Compared to rubber, it achieves a superior cushioning effect without requiring a more complex structure. Furthermore, sponge offers enhanced sound insulation.

Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described in order to better illustrate the principles of the invention and its practical application and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as suited for specific applications.
