Description

Technical Field

[0001] This invention relates to the field of sample tube technology, and in particular to a nonlinear heating and cooling device for sample tubes and its usage method. Background Technology

[0002] The classification and storage of biological samples is a crucial part of life science research. They are indispensable tools for biologists, doctors, pharmacists, and researchers. Biological samples can include various cells, tissues, serum, enzymes, DNA, RNA, etc. These samples are essential materials for biological research and are widely used in basic scientific research, clinical medicine, life science industry, drug development, and other fields.

[0003] Traditional sample tube heating and cooling methods typically involve placing one or more sample tubes on a tray, then placing the entire tray into a programmable heating and cooling device. The device controls the heating and cooling of the sample tubes. Once the sample tubes reach the target temperature, the operator removes the tray from the heating and cooling device and places the sample tubes into long-term storage or testing instruments. However, this method suffers from several drawbacks: the sample tubes cannot be independently and rapidly cooled and heated uniformly when stored in the storage tank, nor can they be independently and rapidly heated and heated uniformly when removed from the storage tank. Furthermore, the temperature of the sample liquid inside and outside the sample tubes is inconsistent during the traditional heating and cooling process. Summary of the Invention

[0013] Secondly, some embodiments of the present invention provide a method of using the sample tube nonlinear heating and cooling device described in any of the embodiments of the first aspect, the method comprising the following steps: Step 1: The staff places the sample tubes that need to be heated or cooled into the test tube tray, and then starts the drive device to move the test tube tray under the cleaning component; Step 2: Start the drive motor, and use the clamping assembly to clamp the top of the sample tube and transport it upwards; Step 3: As the sample tubes are transported upwards, the sterilization components are activated to sterilize the surface of the sample tubes. Step 4: After passing through the disinfection area, the sample tube continues to move upward to the cleaning area, where the wiping component is used to wipe and clean the surface of the sample tube, removing dirt and disinfectant. Step 5: Move the sample tube to the inlet of the first transport tube, start the pneumatic device to transport the sample tube pneumatically, move it to the annular temperature control tube for heating and cooling treatment, and then transfer it to the storage tank for storage.

[0014] The above embodiments of the present invention have the following beneficial effects: This invention utilizes a heating and cooling assembly. A first dispensing device delivers the sample tube into a ring-shaped temperature control tube for heating and cooling. By controlling a first and a second airflow booster device deployed on the ring-shaped temperature control tube, airflow at a specific temperature and speed is blown out. The blown airflow keeps the sample tube at the center of the tube and rotates at a uniform speed along the tube's axis. At this time, the sample liquid is in a spiral rotation state. The heating and cooling of the sample tube is controlled by adjusting the airflow temperature. When the target temperature is reached, the sample tube is sent into a storage tank through a second diversion device. By setting up the heating and cooling assembly, the heating and cooling of the sample liquid inside and outside remains uniform. At the same time, a pneumatic conveying device can independently, quickly, and uniformly cool the sample tube when it is stored in the storage tank and independently, quickly, and uniformly heat it when it is taken out of the storage tank.

[0015] This invention utilizes a disinfection assembly. When the slider moves upward, it drives the second connecting column and rack upward. After rising a certain distance, the rack meshes with a gear on one side, causing the gear to rotate. This, in turn, drives the rotating shaft and turntable to rotate synchronously. At this time, the movable column begins to perform circular motion, causing the movable frame to perform reciprocating motion in the horizontal direction. This, in turn, causes the piston rod and piston to perform up-and-down pulling motion inside the piston cylinder. When the piston rod drives the piston to move towards the top of the piston cylinder, the piston cylinder is under negative pressure. Disinfectant water is drawn into the storage tank through the first infusion tube and then into the piston cylinder. When the piston rod drives the piston to move towards the bottom of the piston cylinder, the disinfectant water inside the piston cylinder is squeezed out through the second infusion tube and sprayed out from the nozzle to sterilize the outer wall of the sample tube, preventing external bacteria and viruses from entering the storage tank.

[0016] This invention, by setting up a wiping assembly, continuously moves the arc-shaped clamp upwards to the wiping area. The upward movement of the arc-shaped clamp causes the sponge wiping plate and the second telescopic rod to make circular motion on the fixed shaft through the rotating ring. Accompanied by the rotation of several sets of sponge wiping plates, the dirt and disinfectant on the surface of the sample tube that has moved upwards are wiped clean. This prevents disinfectant or other dirt from entering the annular temperature control tube for cooling treatment and forming ice that adheres to the surface of the sample tube.

[0023] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] A nonlinear heating and cooling device for sample tubes, such as Figures 1 to 9 As shown, the control box includes a main body 100. A pneumatic conveying assembly 160 is installed on one side of the top of the main body 100. A storage tank 130 is installed on one side of the control box 100 below the pneumatic conveying assembly 160. A storage channel 140 is provided inside the storage tank 130. An active chamber is provided on the front side of the control box 100. A movable tray is slidably connected inside the active chamber. A test tube tray 150 is placed on the upper surface of the movable tray. A cleaning assembly 200 is provided on the top of the test tube tray 150 above the active chamber. A heating and cooling assembly 300 is installed on the top of the control box 100 on one side of the pneumatic conveying assembly 160.

[0025] The heating and cooling assembly 300 includes an annular temperature control tube 360 ​​located above the control box body 100. The annular temperature control tube 360 ​​consists of several mutually isolated (isolated from temperature and light) transparent tubes connected end to end. The transparent tubes are connected to a first diversion device and a second diversion device, which are one-to-many. The output of sample tubes and the diversion of samples into the transparent tubes are controlled by pneumatic switches on the first and second diversion devices. Specifically, the first diversion device includes a first dispensing device 350 fixed to the transparent tube and several sets of first transfer tubes 340 fixedly connected to the first dispensing device 350. A first transfer plate 330 is installed at the other end of the first transfer tube 340. A first transport tube 310 is fixedly connected to the bottom of the first transfer plate 330. The first transport tube 310 passes through the top of the control box body 100 and extends to the top of the movable chamber. A pneumatic device 320 is installed on the outer side of the lower end of the first transport tube 310.

[0026] The second diversion device includes a second distribution device 3910 fixed to the transparent pipeline and several sets of second transfer pipes 3920 fixedly connected to the second distribution device 3910. A second transfer plate 3930 is installed at the other end of each second transfer pipe 3920. A second transport pipe 3940 is fixedly connected to the top of the second transfer plate 3930. Four sets of L-shaped fixing rods 3950 are fixedly installed on the top of the control box body 100 on the four sides of the annular temperature control pipe 360. An infrared camera 3960 is fixedly installed at one end of the top of each L-shaped fixing rod 3950. A support plate 3970 is fixedly installed on the outside of each L-shaped fixing rod 3950. The support plate 3970 is located at the bottom of the annular temperature control pipe 360. Two sets of first airflow boosting devices 370 are fixedly installed at the upper and lower ends of the front side of the annular temperature control pipe 360. Two sets of second airflow booster devices 380 are fixedly connected to the upper and lower ends of the annular temperature control tube 360. A pressure relief pipe 390 is fixedly installed on the outside of the annular temperature control tube 360. A pressure sensor is installed on the outer wall of the pressure relief pipe 390, and an electromagnetic pressure relief valve is installed inside the pressure relief pipe 390. A heat dissipation vent 110 is opened on the front side of the control box body 100, and a dustproof net is fixedly installed on the outside of the heat dissipation vent 110. A control panel 120 is installed on the front side of the control box body 100 above the heat dissipation vent 110. An outlet switch valve is installed at the connection between the first distribution device 350 and the annular temperature control tube 360, and an inlet switch valve is installed at the connection between the second distribution device 3910 and the annular temperature control tube 360. Electromagnetic control valves are installed at the connection between the first airflow booster device 370 and the second airflow booster device 380 and the annular temperature control tube 360.

[0027] The aforementioned first airflow booster device 370 and second airflow booster device 380 can blow out airflows of specific temperatures and speeds as needed. The first and second airflow booster devices are arranged in pairs and at an angle to the transparent pipeline. This angle ensures that the blown airflow can keep the sample tube on the central axis of the transparent pipeline and at the same time ensure that the sample tube can rotate along the axis. The first airflow booster device 370 and the second airflow booster device 380 are both connected to a low-temperature cold gas pipe with a temperature of -80~0℃, a normal-temperature gas pipe with a heating element, and a high-pressure gas pipe with a pressure of not less than 100Pa through independent electromagnetic control valves. The electromagnetic control valve is a two-stage valve. The first-stage valve is connected to the low-temperature cold gas pipe and the normal-temperature gas pipe. The temperature of the final output gas is achieved by controlling the opening and closing ratio of the two gas pipes. The second-stage valve is connected to the high-pressure gas pipe. The gas flow rate is controlled by the opening and closing frequency of the valve.

[0028] It should be noted that when it is necessary to raise the temperature in the annular temperature control tube 360, the input amount of room temperature gas in the aforementioned room temperature gas tube can be increased, thereby raising the overall temperature of the mixture of room temperature gas and low-temperature cold gas in the low-temperature cold gas tube. Those skilled in the art can adjust the gas temperature in the aforementioned room temperature gas tube according to the storage temperature of the sample tube, for example, by adding a heating element.

[0029] Infrared cameras 3960 are installed on both sides of the transparent tube. These infrared cameras 3960 are high-frame-rate cameras and infrared thermometers. The high-frame-rate cameras can detect the current movement speed and rotation speed of the sample tube within the tube. The detection method is as follows: 1. The sample tube has marking lines on its surface. When the sample tube passes through a high frame rate camera, the camera captures an image of the sample tube with the marking line information. By comparing the angle between the marking line and the edge of the transparent tube, the movement state of the sample tube in the transparent tube (parallel, warped, tilted, etc.) can be determined. 2. By comparing the changes of the marker line in adjacent frames, the real-time rotation speed of the sample tube can be calculated. 3. An infrared temperature measuring camera takes real-time pictures of the sample tube, and the temperature information of different areas of the sample tube can be obtained by calculating the images.

[0030] Please refer to this carefully. Figure 2 , Figure 5 , Figure 6 and Figure 7As shown, the cleaning component 200 includes a fixed box 210 fixedly installed at the bottom of the first transport pipe 310.

The moving block 229 is slidably connected to the outer wall of the sliding rod 2291.

[0031] When staff place the sample tubes requiring temperature adjustment into the test tube tray 150, they then activate the drive device to move the test tube tray 150 below the cleaning assembly 200, select the required sample tubes, and allow the sample tubes to enter the fixing box 210. The drive motor 221 is then activated to drive the two sets of threaded screws 222 to rotate, and the slider 223 connected to them begins to slide upward, causing the first telescopic rod 224 and the arc-shaped clamping plate 226 fixed thereto to move upward synchronously. According to the set moving block 229 and sliding rod 2291, the two sets of arc-shaped clamping plates 226 gradually move towards the middle during the upward process, clamping and fixing the top of the sample tube. Then, the sample tube moves vertically upward along the sliding rod 2291, moving it through the disinfection area and the wiping area until it is removed from the fixing box 210.

[0032] Please refer to this carefully.

A one-way valve is installed at one end of both the first infusion tube 2393 and the second infusion tube 2396.

[0033] When slider 223 moves upward, it drives the second connecting column 234 and rack 235 to move upward. After rising a certain distance, rack 235 meshes with gear 233 on one side, causing gear 233 to rotate, thereby driving rotating shaft 232 and turntable 236 to rotate synchronously. At this time, movable column 237 begins to make circular motion, thereby driving movable frame 238 to make horizontal reciprocating motion, thereby driving piston rod 239 and piston 2391 to make up-and-down pulling motion in piston cylinder 2392. When piston rod 239 drives piston 2391 to move to the top of piston cylinder 2392, piston cylinder 2392 is in a negative pressure state, and disinfectant is drawn into storage tank 2394 through first infusion tube 2393 and into piston cylinder 2392. When piston rod 239 drives piston 2391 to move to the bottom of piston cylinder 2392, the disinfectant in piston cylinder 2392 is squeezed through second infusion tube 2396 and sprayed out from nozzle 2397.

Four sets of second telescopic rods 245 distributed in a circle are fixedly installed on the outside of the rotating ring 244. A second spring 246 is provided in each set of second telescopic rods 245. A sponge wiping plate 247 is fixedly installed at the telescopic end of each set of second telescopic rods 245.

[0035] As the arc-shaped clamp 226 continues to move upward to the wiping area, the upward movement of the arc-shaped clamp 226 drives the sponge wiping plate 247 and the second telescopic rod 245 to make circular motion on the fixed shaft 243 through the rotating ring 244. Accompanied by the rotation of several sets of sponge wiping plates 247, the dirt and disinfectant on the surface of the sample tube that has moved upward are wiped clean, preventing disinfectant or other dirt from entering the annular temperature control tube 360 ​​for cooling treatment and forming ice that adheres to the surface of the sample tube.

[0036] In use, after being processed by the cleaning component 200, the sample tube is then fed into the annular temperature control tube 360 ​​for heating and cooling via the first diversion device. The first airflow booster 370 and the second airflow booster 380, deployed on the annular temperature control tube 360, blow airflow at a specific temperature and speed. This airflow keeps the sample tube centered within the annular temperature control tube 360, causing it to rotate uniformly along its axis (the sample liquid is in a spiral rotation state). The temperature of the sample tube is controlled by adjusting the airflow temperature. Once the target temperature is reached, the sample tube is fed into the storage tank 130 via the second diversion device. Any parts of this device not described herein are the same as or can be implemented using existing technology.

[0037] The present invention also discloses a method of using a sample tube nonlinear heating and cooling device applied to any of the above embodiments. Figure 10 The flowchart 1000 describes a method for using a nonlinear heating and cooling device for sample tubes according to the present invention, which includes the following steps: Step 1001: The staff places the sample tubes that need to be heated or cooled into the test tube tray, and then starts the drive device to move the test tube tray under the cleaning component; Step 1002: Start the drive motor, clamp the top of the sample tube with the clamping assembly and transport it upwards; Step 1003: As the sample tube is transported upwards, the sterilization component is activated to sterilize the surface of the sample tube. Step 1004: After passing through the disinfection area, the sample tube continues to move upward to the cleaning area, where it is wiped clean with the wiping component to remove dirt and disinfectant from the sample tube surface. Step 1005: The sample tube is moved to the inlet of the first transport tube, and the pneumatic device is activated to transport the sample tube pneumatically. It is then moved to the annular temperature control tube for heating and cooling treatment, and then transferred to the storage tank for storage.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
