Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a sample constant temperature heater for detecting hydatid DNA in dog feces. Background Art

[0002] Constant temperature heaters, also known as constant temperature metal baths, dry thermostats, and dry incubators, are widely used for sample storage and reactions, DNA amplification, pre-denaturation for electrophoresis, and serum coagulation. Microcomputer-controlled, they electrically heat a high-purity aluminum standard module. To use, place the centrifuge tubes in the module, cover it with an insulating cover, and set the temperature and other parameters. The constant temperature heater then begins operation. Once the operation is complete, remove the centrifuge tubes from the machine one by one.

[0003] When testing dog feces for echinococcosis DNA, a 0.1 gram fecal sample is added to 300-500 μl of lysis buffer, which is then placed in a 95°C constant-temperature heater for 5 minutes to lyse the sample. This sample is then used as a DNA template. Existing constant-temperature heaters are unable to remove all samples from the device at once. Furthermore, with large numbers of dog fecal samples, often as many as 200 or more, each sample needs to be removed from the constant-temperature heater one by one after lysis is complete, which is time-consuming and inefficient, reducing the efficiency of the device.

[0004] Therefore, it is necessary to provide a sample constant temperature heater for detecting echinococcosis DNA in dog feces to solve the above technical problems. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0025] Example 1:

[0026] like Figure 1-3 As shown, the sample constant temperature heater for detecting echinococcosis DNA in dog feces provided by the present invention includes: a heater body 1. In this embodiment, the heater body 1 adopts a constant temperature heater structure design with model HtPot70, and a detachable and replaceable standard module 2 is installed on the heater body 1. The standard module 2 can also adopt a constant temperature heater structure design with model HtPot70. The standard module 2 is made of aluminum material. The heater body 1 can heat the standard module 2 at a constant temperature. A quick-release plate 3 is installed on the top of the standard module 2. It is worth noting that one heater body 1 is used with several standard modules 2 of different calibers and quick-release plates 3 compatible with the standard module 2, and one standard module 2 is used with at least two quick-release plates 3. During use, the centrifuge tube containing the dog feces sample (0.1g) and the lysate (300ul-500ul) is passed through the quick-release plate 3 and inserted into the standard module 2. The other centrifuge tubes are operated according to the same standard, and the tube caps of the centrifuge tubes are blocked by the quick-release plate 3, so that the tube caps 3 cannot pass through the quick-release plate 3. Then the heater body 1 heats the standard module 2 to 95°C at a constant temperature for 5 minutes. After the heating is completed, the equipment stops, and the two sides of the quick-release plate 3 are held and pulled upward to make the quick-release plate 3 detach from the top of the standard module 2. Since the tube caps of the centrifuge tubes are stuck on the top of the quick-release plate 3, the quick-release plate 3 rises and drives all the centrifuge tubes to detach from the standard module 2 at the same time, so that all the samples can be removed at the same time, saving a lot of time. Then another quick-release plate 3 of the same standard is plugged into the top of the standard module 2, and the equipment can start working again, thereby greatly improving the efficiency of the equipment.

[0027] By setting up the heater body 1 and the standard module 2, and plugging and installing the quick-release plate 3 on the standard module 2, all samples inserted on the standard module 2 can be removed at the same time by pulling the quick-release plate 3 upward, saving the time required to remove the samples, improving work efficiency, and at the same time improving the use efficiency of the equipment.

[0028] Example 2:

[0029] like Figure 2-3As shown, a plurality of standard slots 4 are evenly arranged on the standard module 2, and a plurality of standard jacks 5 are evenly arranged on the quick-release plate 3. The aperture of the standard jack 5 is slightly larger than the aperture of the standard slot 4. When in use, the quick-release plate 3 is plugged into the top of the standard module 2, the standard jacks 5 are aligned one by one with the standard slots 4, the bottom of the centrifuge tube passes through the standard jack 5 and is inserted into the standard slot 2, and the tube cap is blocked by the top of the standard jack 5.

[0030] By providing the standard slot 4 and the standard jack 5 , the centrifuge tube can be conveniently inserted and installed for use.

[0031] Example 3:

[0032] like Figure 2-3 As shown, both sides of the standard module 2 are symmetrically provided with plug-in slots 6, and correspondingly, four plug-in rods 7 are installed at the bottom of the quick-release plate 3, and the plug-in rods 7 are plugged into the plug-in slots 6 one by one. When in use, the plug-in rods 7 at the bottom of the quick-release plate 3 are inserted into the plug-in slots 6 to plug the quick-release plate 3 into the standard module 2. After heating is completed, the quick-release plate 3 is removed together with the centrifuge tube, and the quick-release plate 3 is placed on the desktop. The plug-in rods 7 support the quick-release plate 3 so that there is a certain distance between the bottom of the centrifuge tube and the desktop, thereby keeping all centrifuge tubes vertical to prevent them from tipping over.

[0033] By providing the plug-in slot 6 and the plug-in rod 7, the standard module 2 can be easily plugged into the quick-release plate 3, and the quick-release plate 3 can be easily supported so that it maintains a certain distance from the desktop and can be stably placed on the desktop for use.

[0034] Example 4:

[0035] like Figure 3 As shown, a rubber sleeve 8 is installed at the bottom of the plug-in rod 7. When in use, when the rubber sleeve 8 contacts the desktop, it plays an anti-slip role, making the quick-release plate 3 more stable when placed on the desktop. When the plug-in rod 7 is inserted into the plug-in slot 6, the rubber sleeve 8 contacts the inner wall of the plug-in slot 6. When the device activates the centrifugal program, the damping effect of the rubber sleeve 8 makes it difficult for the plug-in rod 7 to fall out of the plug-in slot 6, making the state of the quick-release plate 3 more stable.

[0036] By installing the rubber sleeve 8 at the bottom of the plug-in rod 7 , the stability of the quick-release plate 3 can be improved.

[0037] Example 5:

[0038] like Figure 3 As shown, integrally formed handles 9 are provided on both sides of the quick release plate 3 . When in use, the handles 9 can be grasped to facilitate moving the quick release plate 3 .

[0039] By providing handles 9 on both sides of the quick release plate 3 , the quick release plate 3 can be conveniently lifted and moved.

[0040] Example 6:

[0041] like Figure 2 As shown, a connecting ear 10 is installed on the standard module 2. When in use, a screw is passed through the connecting ear 10 to connect and fix the standard module 2 to the heater body 1.

[0042] By installing the connecting ears 10 on the standard module 2 , the installation and removal of the standard module 2 can be facilitated.

[0043] Working principle: When in use, the centrifuge tube containing the dog feces sample (0.1g) and the lysate (300ul-500ul) is passed through the quick-release plate 3 and inserted into the standard module 2. The other centrifuge tubes are operated according to the same standard, and the tube caps of the centrifuge tubes are blocked by the quick-release plate 3, so that the tube caps 3 cannot pass through the quick-release plate 3. Then the heater body 1 heats the standard module 2 to 95°C at a constant temperature for 5 minutes. After heating is completed, the equipment stops, hold both sides of the quick-release plate 3, and pull it upward to make the quick-release plate 3 detach from the top of the standard module 2. Since the tube caps of the centrifuge tubes are stuck on the top of the quick-release plate 3, the quick-release plate 3 rises and drives all the centrifuge tubes to detach from the standard module 2 at the same time, so that all samples can be removed at the same time, saving a lot of time. Then another quick-release plate 3 of the same standard is plugged into the top of the standard module 2, and the equipment can start working again, thereby greatly improving the efficiency of the equipment.
