Description

Technical Field

[0001] This utility model relates to the technical field of Helicobacter pylori sample storage, and in particular to a Helicobacter pylori sample storage device. Background Technology

[0002] Proper storage of Helicobacter pylori samples is crucial for ensuring the accuracy of subsequent testing and research. Short-term samples should be stored at 2–8°C. For long-term storage, if testing cannot be performed within 72 hours, samples should be frozen immediately upon receipt and stored at -20°C or lower. Samples should be transported in empty containers, and the containers should be kept airtight during storage to prevent contamination and moisture evaporation.

[0003] Among existing Helicobacter pylori sample storage devices, such as the adjustable bacterial sample storage device for laboratory use disclosed in utility model patent application number 202121209252.7, when the bacteria inside the dish are anaerobic, the sealing cap is first placed on the outside of the fixing tube, and then the sealing cap is tightened on the top of the dish to ensure the stability of the internal environment of the dish. It adopts the principle of a tinderbox to ensure that users can provide a good temperature environment for bacteria when electricity is inconvenient, thus facilitating users to collect and preserve samples in harsh environments.

[0004] However, before storing Helicobacter pylori samples, the bacterial suspension should be manually agitated with a pipette to mix it thoroughly. Do not use an electric shaker, as this may damage the bacterial structure. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a Helicobacter pylori sample storage device that, by setting up a pumping mechanism and a heat preservation mechanism, allows for gentle mixing of Helicobacter pylori samples during storage, preventing damage to the bacterial structure, and also allows for heat preservation to prevent the failure of active cooling due to special circumstances.

[0006] This utility model discloses a Helicobacter pylori sample storage device, which includes a liquid storage mechanism; it also includes a sealing mechanism, a pumping mechanism, a heat preservation mechanism, and a locking mechanism. The sealing mechanism is installed on the liquid storage mechanism, the pumping mechanism is installed inside the liquid storage mechanism, the heat preservation mechanism is installed outside the liquid storage mechanism, and the locking mechanism is installed on the liquid storage mechanism.

[0007] The liquid storage mechanism stores the liquid, the sealing mechanism seals it, the pumping mechanism mixes the samples, the insulation mechanism maintains the temperature, and the locking mechanism locks it in place. By injecting the sample into the liquid storage mechanism, sealing it with the sealing mechanism, mixing the sample by pressing the pumping mechanism, fixing the insulation mechanism to the outside of the liquid storage mechanism with the locking mechanism, and stabilizing the temperature of the liquid storage mechanism by cooling it with water inside, the Helicobacter pylori sample can be gently mixed during storage to prevent damage to the bacterial structure and can be kept warm to prevent failure to actively cool under special circumstances.

[0008] Preferably, the liquid storage mechanism includes a liquid storage tube and a diversion tube, the diversion tube being installed inside the liquid storage tube and having multiple sets of connecting holes; the liquid storage tube stores the sample, and the diversion tube allows the sample to circulate.

[0009] Preferably, the sealing mechanism includes a cap and a rubber gasket. The cap is threaded onto the liquid storage tube, and the rubber gasket is installed inside the cap. The cap and the liquid storage tube are threaded together so that the cap presses the rubber gasket tightly onto the liquid storage tube to seal it.

[0010] Preferably, the pumping mechanism includes an inner liner and a spring. The inner liner is slidably installed inside the liquid storage tube and is connected to the liquid storage tube via the spring. The sample is pumped by pressing the inner liner, and the inner liner is reset by the spring.

[0011] Preferably, the insulation mechanism includes an insulation chamber and a sealing rubber. The insulation chamber is fitted onto the outside of the liquid storage pipe, and the sealing rubber is installed inside the insulation chamber. The water in the insulation chamber is frozen to prevent drastic temperature changes in the liquid storage pipe in a short period of time, and the sealing rubber prevents structural cracking caused by the freezing expansion of the liquid.

[0012] Preferably, the locking mechanism includes a threaded cover and two sets of limiting rings. The threaded cover is installed on the insulation chamber by threads, and the two sets of limiting rings are installed on the liquid storage pipe. The insulation chamber is tightened and fixed by the threaded cover, and the limiting rings limit the position of the insulation chamber and the threaded cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by injecting the sample into the liquid storage mechanism, sealing the liquid storage mechanism with a sealing mechanism, mixing the sample by pressing the pump mechanism, fixing the heat preservation mechanism to the outside of the liquid storage mechanism with a locking mechanism, and stabilizing the temperature of the liquid storage mechanism by water cooling inside the heat preservation mechanism, the sample can be gently mixed during the storage of Helicobacter pylori samples to prevent damage to the bacterial structure, and heat preservation treatment can be performed to prevent the failure of active cooling due to special circumstances.

The sealing mechanism 2 is installed on the liquid storage mechanism 1, the pumping mechanism 3 is installed inside the liquid storage mechanism 1, the heat preservation mechanism 4 is installed outside the liquid storage mechanism 1, and the locking mechanism 5 is installed on the liquid storage mechanism 1.

[0023] The liquid storage mechanism 1 stores the liquid, the sealing mechanism 2 seals the liquid, the pumping mechanism 3 pumps the liquid to mix it, the heat preservation mechanism 4 keeps the liquid warm, and the locking mechanism 5 locks the liquid.

[0024] Liquid storage mechanism 1 includes a liquid storage tube 11 and a diversion tube 12. The diversion tube 12 is installed inside the liquid storage tube 11 and has multiple sets of connecting holes.

[0025] The sealing mechanism 2 includes a cap 21 and a rubber gasket 22. The cap 21 is threaded onto the liquid storage tube 11, and the rubber gasket 22 is installed inside the cap 21.

[0026] The pumping mechanism 3 includes an inner liner 31 and a spring 32. The inner liner 31 is slidably installed inside the liquid storage tube 11, and the inner liner 31 is connected to the liquid storage tube 11 through the spring 32.

[0029] The sample is stored through the storage tube 11 and circulated through the diversion tube 12.

The sample is pumped by pressing the inner liner 31, and the inner liner 31 is reset by the spring 32. The insulated chamber 41 is tightened and fixed by the threaded cap 51. The insulated chamber 41 and the threaded cap 51 are limited by the limiting ring 52. Water in the frozen insulated chamber 41 is used to keep the temperature inside the storage tube 11 from changing drastically in a short time. The sealing rubber 42 prevents the structure from cracking due to the expansion of the liquid during freezing. Thus, during the storage of Helicobacter pylori samples, the samples can be gently mixed to prevent damage to the bacterial structure, and the samples can be kept warm to prevent failure to actively cool due to special circumstances.

The sample is pumped by pressing the inner liner 31, and the inner liner 31 is reset by the spring 32. The insulated chamber 41 is tightened and fixed by the threaded cap 51. The insulated chamber 41 and the threaded cap 51 are limited by the limiting ring 52. The water in the insulated chamber 41 is frozen to prevent drastic temperature changes in the storage tube 11 in a short time. The sealing rubber 42 prevents the structure from cracking due to the expansion of the liquid during freezing.

[0031] The main function achieved by this utility model is: during the storage of Helicobacter pylori samples, by setting up a pumping mechanism and a heat preservation mechanism, the samples can be gently mixed during the storage process to prevent damage to the bacterial structure, and heat preservation treatment can be performed to prevent the failure to actively cool due to special circumstances.
