Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and specifically relates to a centrifuge tube rack for blood samples. Background Technique

[0002] When using glass tubes, the centrifugal force should not be too large, and a rubber pad needs to be placed to prevent the tubes from breaking. Generally, glass tubes are not selected for high-speed centrifuges. If the lid of the centrifuge tube has poor sealing, the liquid cannot be filled to the brim (for high-speed centrifuges using angle rotors) to prevent overflow and loss of balance. The consequence of overflow is to contaminate the rotor and the centrifuge chamber, affecting the normal operation of the sensor. When performing ultra-high-speed centrifugation, the liquid must fill the centrifuge tube completely because ultra-high-speed centrifugation requires a high vacuum, and only by filling it completely can the deformation of the centrifuge tube be avoided. In the field of biological science, especially in biochemistry and molecular biology research, it has been widely used, and every biochemistry and molecular biology laboratory needs to prepare various types of centrifuges. Centrifugation technology is mainly used for the separation and preparation of various biological samples. The biological sample suspension is placed in a centrifuge tube and under high-speed rotation, due to the huge centrifugal force, the suspended tiny particles (such as organelles, precipitates of biological macromolecules, etc.) settle at a certain speed, thus being separated from the solution.

[0003] The application number is CN201920267700.5, which discloses a centrifuge tube rack. The centrifuge tube rack includes a base, a top of the rack and a connecting part. The top of the rack is disposed opposite to the base. The top of the rack includes a rack body and positioning ropes. The rack body is a hollow structure. Both ends of the positioning ropes are detachably connected to the rack body. The number of positioning ropes is multiple, and the multiple positioning ropes are horizontally and vertically interwoven to form holes for the centrifuge tubes to pass through. One end of the connecting part is connected to the base, and the other end is connected to the rack body. By setting the positioning ropes, the multiple positioning ropes are horizontally and vertically interwoven to form holes for the centrifuge tubes to pass through, so that the centrifuge tubes can be kept upright. Moreover, since the positioning ropes are detachably connected to the rack body, by changing the connection position of the positioning ropes to the rack body, the size of the holes formed by the positioning ropes can be changed, so that the centrifuge tube rack can be applicable to centrifuge tubes of various specifications.

[0004] Although the above-mentioned utility model forms holes for the centrifuge tubes to pass through by horizontally and vertically interweaving multiple positioning ropes so that the centrifuge tubes can be kept upright. Moreover, since the positioning ropes are detachably connected to the rack body, by changing the connection position of the positioning ropes to the rack body, the size of the holes formed by the positioning ropes can be changed, so that the centrifuge tube rack can be applicable to centrifuge tubes of various specifications, the drawback is that when in use, the lid part is not fixed, so there may be a risk of tilting during subsequent collisions.

[0005] Therefore, it is necessary to install an adjustable cover plate assembly on the device, which can fix the centrifugal tube after it is placed when using the device, avoid the shaking of the internal centrifugal tube caused by collision, and has a good protective effect.

[0028] The device box body assembly 1 includes a carrier 101. Installation chutes 102 are opened on both sides inside the carrier 101, and a moisture absorption pad 103 is installed at the bottom thereof. A limit seat 104 is installed on the top of the moisture absorption pad 103, and the carrier 101 is supported and fixed through the limit seat 104 at the bottom.

[0029] The limit plate assembly 2 includes a mounting plate 201. Slide edges 202 are installed on both sides of the mounting plate 201, and a number of limit silicone notch openings 203 are opened in the middle thereof. The slide edges 202 are installed inside the installation chutes 102. A glass tube 204 is installed in the middle of the limit silicone notch openings 203, and a bottle stopper 205 is installed on the top of the glass tube 204. The mounting plate 201 can be slidably installed inside the installation chutes 102 on the inner side of the carrier 101 through the slide edges 202 on both sides to complete the assembly work.

[0030] The adjusting cover plate assembly 3 includes a rotating shaft 301. An interlocking rotating rod 302 is installed inside the rotating shaft 301, and an interlocking plate 303 is installed outside it. They are simultaneously installed on the top of both sides of the carrier 101. A connecting rod 304 is installed at the end of the interlocking plate 303. A cover body 305 is installed inside the connecting rod 304. A positioning sponge top 306 is installed inside the cover body 305. A bottle stopper 205 is correspondingly installed at the bottom of the positioning sponge top 306. Rotate the rotating shaft 301, and then the interlocking rotating rod 302 installed inside will drive the rotating shaft 301 on the other side to operate. At the same time, the interlocking plate 303 outside it drives the connecting rod 304 at the end to move. Then, the cover body 305 installed on the connecting rod 304 can perform the working effect of pressing and sealing along its movement track.

When a column is filled, limit it by adjusting the pressing ring assembly 4. When performing the limiting work, the pressing ring 403 limited on the storage hook 401 moves forward, and presses on the bottle stopper 205 through the pressing notch 4031 therein to form a fixed pressing effect. Fix the limit every time a column is completed until the entire carrier 101 is loaded. Then, cover the device box body assembly 1 by adjusting the cover plate assembly 3. When covering, first rotate the rotating shaft 301, and then the linkage rotating rod 302 installed inside will drive the rotating shaft 301 on the other side to operate. At the same time, the linkage plate 303 on the outside drives the connecting rod 304 at the end to move. Then, the cover body 305 installed on the connecting rod 304 can perform the pressing and covering work effect along its movement track. Then, perform the transportation work. When picking up the glass tube 204 inside later, only need to drive the cover body 305 to flip upward through the rotating shafts 301 on both sides, lift the pressing ring 403 from the bottle stopper 205, and then slide backward. Under the action of the limit ball 402, the pressing ring 403 can be prevented from falling off, and it is hooked on the storage hook 401. Then, the glass tube 204 can be picked out.
