Description

Technical Field

[0001] This utility model belongs to the field of blood testing, specifically a separation device for blood protein testing. Background Technology

[0002] Blood protein testing is a commonly used diagnostic method in medicine. It is mainly used to detect the content and type of proteins in the blood, thereby helping doctors understand the patient's physical condition and diagnose related diseases. In blood protein testing, protein separation is a crucial step. Centrifuges can use the powerful centrifugal force generated by high-speed rotation to separate components of different densities in the blood under the action of centrifugal force, thereby achieving the purpose of separation.

[0003] When using a centrifuge to separate blood, the centrifuge tubes need to be placed in the centrifuge's placement slot. During high-speed rotation, because the centrifuge tubes are not equipped with a protective mechanism, they are prone to falling out of the placement slot. This can not only damage the centrifuge tubes and waste blood, but also affect the experimental process and reduce the safety of the experimental operation.

[0004] In summary, this invention provides a separation device for blood protein detection to solve the above-mentioned problems. Utility Model Content

[0022] Example 1

[0023] like Figure 1-4 As shown, this is the first embodiment of the present invention, which provides a separation device for blood protein detection, comprising:

[0024] The centrifugation unit 1 includes a centrifuge body 101, a placement rack 102 disposed on the top of the centrifuge body 101, a placement slot 103 opened on the top of the placement rack 102, and a support assembly 104 disposed between the centrifuge body 101 and the placement rack 102.

[0025] The protective unit 2 includes a support ring 201 detachably connected to the inner cavity of the placement groove 103, a rotating plate 202 movably connected to the inner cavity of the support ring 201 via a bearing, and a positioning component 203 disposed in the inner cavity of the rotating plate 202.

[0026] like Figure 1-4As shown, the centrifuge body 101, as the core part of the entire device, provides the power for high-speed rotation, causing blood samples to separate under the action of centrifugal force. The placement rack 102 is used to support the top components, and the placement slot 103 is used to place the support ring 201 and can also perform initial positioning. The support assembly 104 is used to support the placement rack 102 and can also adjust its height so that the device can be used for centrifuge tubes of different heights. The support ring 201 is detachably connected in the placement slot 103 to provide support for the rotating plate 202 and ensure that the rotating plate 202 can remain stable during rotation. The rotating plate 202 is movably connected to the support ring 201 through a bearing, so that the rotating plate 202 can rotate with the centrifuge tubes during centrifugation while maintaining its positional stability. The positioning assembly 203 can further improve the stability of the centrifuge tubes during centrifugation and prevent them from falling off.

[0027] Example 2

[0028] Reference Figure 2 and 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] In this embodiment, the support assembly 104 includes a hollow plate 1041 fixedly connected to both sides of the top of the centrifuge body 101, a support plate 1042 slidably connected to the inner cavity of the hollow plate 1041, the top of the support plate 1042 being fixedly connected to the bottom of the placement rack 102, and an electric push rod 1043 fixedly connected to the bottom of the inner cavity of the hollow plate 1041, the output end of the electric push rod 1043 being fixedly connected to the bottom of the support plate 1042.

[0030] The support assembly 104 also includes support blocks 1044 fixedly connected to both sides of the placement rack 102, and a limiting plate 1045 movably connected to the top of the support block 1044 via a movable pin. The limiting plate 1045 is movably connected to the top of the support ring 201.

[0031] like Figure 2 and 3 As shown, the hollow plate 1041 and the support plate 1042 are slidably connected, allowing the placement rack 102 to be adjusted in height as needed to accommodate centrifuge tubes of different sizes and centrifugation speed requirements. The electric push rod 1043 provides the ability to automatically adjust the height of the placement rack 102, improving the convenience and accuracy of operation. The support block 1044 and the limiting plate 1045 work together to further stabilize the placement rack 102, preventing it from shaking during centrifugation and ensuring the separation effect.

[0032] Example 3

[0033] Reference Figure 4This is the third embodiment of the present invention, which is based on the first two embodiments.

[0034] In this embodiment, the positioning component 203 includes a positioning sleeve 2031 fixedly connected to the inner cavity of the rotating plate 202, and there are four positioning sleeves 2031; a positioning block 2032 slidably connected to the inner cavity of the positioning sleeve 2031; and a stainless steel spring 2033 fixedly connected to the top of the positioning block 2032. The top of the stainless steel spring 2033 is fixedly connected to the inner wall of the positioning sleeve 2031.

[0035] The positioning component 203 also includes anti-detachment grooves 2034 formed on both sides of the inner cavity of the positioning sleeve 2031, and anti-detachment blocks 2035 fixedly connected to both sides of the positioning block 2032. One side of the anti-detachment block 2035 extends into the inner cavity of the anti-detachment groove 2034 and is slidably connected to its inner cavity.

[0036] like Figure 4 As shown, the positioning sleeve 2031 and the positioning block 2032 are slidably connected to achieve precise positioning and fixation of the centrifuge tube, preventing it from shifting or falling off during centrifugation. The stainless steel spring 2033 provides elastic support for the positioning block 2032, enabling it to automatically adapt to centrifuge tubes of different sizes and maintain a stable clamping force. The anti-detachment groove 2034 and the anti-detachment block 2035 work together to prevent the positioning block 2032 from falling off due to vibration or centrifugal force during centrifugation, ensuring stable clamping of the centrifuge tube.

[0037] In use, first place the centrifuge tubes containing blood on top of the centrifuge body 101. Move the support ring 201 so that the tops of the centrifuge tubes are inserted into the multiple positioning sleeves 2031. Then, activate the electric push rod 1043 via the external controller to adjust the height of the support plate 1042 until the placement rack 102 is at the same height as the centrifuge tubes. Next, press the support ring 201 to place it into the placement slot 103. Then, rotate the limiting plate 1045 to limit the support ring 201 and prevent it from being supported. Ring 201 detaches from the inside of the placement slot 103. At this time, the top of the centrifuge tube presses against the positioning block 2032 and moves it upward inside the positioning sleeve 2031. The stainless steel spring 2033 will deform due to the pressure, and the return force of the stainless steel spring 2033 can provide a return force for the positioning block 2032, so that it presses and positions the centrifuge tube. Then, the centrifuge body 101 is started through the external controller to centrifuge and separate the blood in the centrifuge tube. After the centrifugation operation is completed, the centrifuge tube can be removed by reversing the above operation.
