Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a medical sampler convenient for storage. Background Art

[0002] At present, when detecting viruses, sampling and detection are generally carried out by means of throat swab sampling. The sampling cotton swab is inserted into the deep part of the oral cavity to dip the human secretion, and then detected through the reaction of the reagent solution. The existing sampler is a cotton swab and a reagent tube packaged in a packaging bag, and the two form a sampler.

[0003] For people who are inconvenient to go to the hospital, on-site sampling is generally carried out by staff, and then the samples are transported back to the laboratory for detection. However, the existing sampler does not have a refrigeration function and is not convenient for long-term storage. If the transportation time is too long, the samples will deteriorate, thus affecting the accuracy of the detection. Therefore, there are still drawbacks and deficiencies in the existing technology. Summary of the Utility Model

[0004] The utility model provides a medical sampler convenient for storage to solve the problems raised in the background art.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a medical sampler convenient for storage, including a reagent tube, a sealing cover and a cooling tube. An installation opening is provided at the top of the cooling tube. A clear water cavity and a reagent cavity are sequentially arranged in the cooling tube from top to bottom. Distilled water is placed in the clear water cavity, and air, ammonium nitrate and potassium nitrate are placed in the reagent cavity.

[0015] The following further describes the present utility model with reference to the drawings. The following description is based on the directions in the Figure 1 drawings.

[0016] As Figures 1-3 shown, the present utility model provides a medical sampler convenient for storage, including a reagent tube 1, a sealing cover 2, and a cooling tube 3. An installation port 4 is opened at the top of the cooling tube 3. A clear water chamber 5 and a medicament chamber 6 are sequentially arranged in the cooling tube 3 from top to bottom. Distilled water is placed in the clear water chamber 5, and air, ammonium nitrate, and potassium nitrate are placed in the medicament chamber 6. In this embodiment, air accounts for 20% of the volume of the medicament chamber 6, and the mass ratio of ammonium nitrate to potassium nitrate is 7:3. The clear water chamber 5 and the medicament chamber 6 are separated by a first film 7; the mouth of the reagent tube 1 is detachably connected to the sealing cover 2. A reagent liquid is placed in the reagent tube 1. The reagent tube 1 extends from the installation port 4 into the cooling tube 3, and the reagent tube 1 is threadedly connected to the cooling tube 3.

[0017] Specifically, during use, in the initial position, the bottom of the reagent tube 1 is located above the first thin film 7. The staff collects the sample with a cotton swab, puts the sample into the reagent tube 1, and then covers the opening of the reagent tube 1 with the sealing cap 2 to complete the sampling. When it is necessary to cool the sample, rotate the reagent tube 1. Since the reagent tube 1 and the cooling tube 3 are threadedly connected, the reagent tube 1 will move downward. The downward-moving reagent tube 1 can pierce the first thin film 7, so that the ammonium nitrate and potassium nitrate mixture dissolves in distilled water to lower the temperature, and then the sample can be cooled down.

[0018] The utility model makes the reagent tube 1 move downward by rotating the reagent tube 1. The downward-moving reagent tube 1 pierces the first thin film 7, so that the ammonium nitrate and potassium nitrate mixture dissolves in distilled water, thereby cooling the sample in the reagent tube 1, and then the storage time of the sample can be extended.

[0019] In some embodiments, a first limiting ring 8 and a first limiting plate 9 are fixedly connected to the outer side wall of the reagent tube 1 in sequence from top to bottom. A bent crease groove is recessed in the first limiting plate 9 near the root position, and the bottom of the first limiting plate 9 contacts the top of the cooling tube 3. Specifically, when it is necessary to cool the sample, after breaking the first limiting plate 9, the reagent tube 1 can be rotated until the top of the cooling tube 3 contacts the first limiting ring 8. By providing the first limiting plate 9, the reagent tube 1 can be blocked, so as to prevent the first thin film 7 from being damaged due to accidental rotation of the reagent tube 1, and further avoid waste of the sampler.

[0020] In some embodiments, an air cavity 10 and a reagent cavity 11 are arranged in the reagent tube 1 in sequence from top to bottom. The air cavity 10 and the reagent cavity 11 are separated by a second thin film 12, and the reagent liquid is located in the reagent cavity 11. Specifically, during use, the staff puts the cotton swab carrying the sample into the reagent tube 1 and pierces the second thin film 12 with the cotton swab, so that the sample is immersed in the reagent liquid, which is convenient for the staff to operate on site.

[0021] In some embodiments, it further includes a sampling rod 13. One end of the sampling rod 13 penetrates through the sealing cover 2 and extends into the reagent tube 1. The sampling rod 13 is threadedly connected to the sealing cover 2, and a sampling cotton head 14 is provided at the bottom of the sampling rod 13. Specifically, during use, in the initial position, the sampling cotton head 14 is located above the second film 12. Open the sealing cover 2, perform sampling through the sampling cotton head 14. After sampling is completed, cover the sealing cover 2, and then rotate the sampling rod 13. Since the sampling rod 13 and the sealing cover 2 are threadedly connected, the sampling rod 13 will move downward. The downward-moving sampling rod 13 can pierce the second film 12, enabling the sample to be immersed in the reagent liquid. The utility model combines the reagent tube 1, the sampling rod 13, the sampling cotton head 14, and the reagent liquid together, thus facilitating transportation and storage. The sampling cotton head 14 and the reagent liquid are separated by the second film 12. During use, rotating the sampling rod 13 can pierce the second film 12, enabling the sample to be immersed in the reagent liquid, thereby facilitating on-site operation by the staff.

[0022] In some embodiments, a second limiting ring 15 and a second limiting plate 16 are fixedly connected to the outer side wall of the sampling rod 13 in sequence from top to bottom. The second limiting plate 16 is recessed with a bending crease groove near the root position, and the bottom of the second limiting plate 16 contacts the top of the sealing cover 2. Specifically, when the sampling rod 13 needs to move downward, after breaking the second limiting plate 16, the sampling rod 13 can be rotated until the bottom of the second limiting ring 15 contacts the sealing cover 2. By providing the second limiting plate 16, the sampling rod 13 can be blocked, thereby preventing the sampling rod 13 from being accidentally rotated to damage the second film 12, and further avoiding waste of the sampler.

[0023] The above embodiments can be combined with each other.

[0024] The above embodiments do not impose any formal restrictions on the shape, material, structure, etc. of the present utility model. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model all fall within the protection scope of the technical solution of the present utility model.
