Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration tools, and particularly relates to a drug refrigerated storage device. Background Art

[0002] The storage of refrigerated drugs is an important category in drug storage classification. Certain heat-labile biological agents, active agents, and protease drugs need to be continuously maintained in an environment of 2-8°C throughout the entire process from production to use to ensure the quality of the drugs and the safety of patients when using drugs. The chemical reaction of drugs accelerates with the increase of temperature. When the temperature rises by 10°C, the chemical reaction rate can increase by 2-4 times. Therefore, too high a drug storage temperature will accelerate protein denaturation, the drug degradation reaction will speed up, the biological activity will decrease or be lost, thus affecting the efficacy of the drug. In severe cases, the drug dosage form may be damaged, which may have unpredictable effects on patients, and even the probability of low-probability toxic and side effects cannot be excluded, increasing the probability of clinical adverse events of drugs. Taking growth factors as an example, this type of drug belongs to protein drugs and requires storage in the dark at 2-8°C, and should be avoided being placed in high-temperature or frozen environments.

The bottom fixed disk 4 is arranged at the bottom of the inner cylinder 1 for drug storage for supporting, fixing and stabilizing the inner cylinder 1 for drug storage. The inner cylinder 1 for drug storage can be placed in a thermos cup with a suitable size, the bottom fixed disk 4 is in contact with the inner bottom of the thermos cup, and the middle support ring 3 is in contact with the inner side wall of the thermos cup to limit the inner cylinder 1 for drug storage, and the cold source medium is filled inside the thermos cup to achieve the effect of refrigerating the drug.

[0026] Through the above solution, the present utility model uses an ordinary heat-insulated cup with good heat-insulating performance as a drug refrigeration carrier, designs an inner frame structure with a device for fixing the drug to be refrigerated and a function of filling a cold source medium therein, and relies on the cold source medium to maintain the temperature under the condition of good sealing of the heat-insulated cup, so as to achieve the purpose of short-term refrigerated transportation of drugs.

[0027] In a preferred embodiment, a first soft spring 8 is arranged inside the drug storage inner cylinder 1. The first end of the first soft spring 8 is connected to the inner bottom of the drug storage inner cylinder 1, and the second end of the first soft spring 8 is connected with a first circular gasket 6. When the drug is placed in the drug storage inner cylinder 1, a flexible extrusion force can be given to the drug to better protect the drug.

[0028] As an example, the first circular gasket 6 can be a rubber disc.

[0029] As a further example, the length of the first soft spring 8 can be set to 1 - 3 cm, and the thickness of the first circular gasket can be set to 0.5 - 1 cm.

[0030] In a preferred embodiment, a flexible block 7 is further arranged on the first circular gasket 6 for further protecting the drug.

[0031] As an example, the flexible block 7 can be a sponge block, a soft silicone block, etc.

[0032] Specifically, in this solution, the drug storage inner cylinder 1 and the inner cylinder cover 2 are in threaded connection, and a second soft spring 5 is arranged on the inner bottom surface of the inner cylinder cover 2; the first end of the second soft spring 5 is connected to the inner cylinder cover 2, and the second end is connected with a second circular gasket 9 for giving a flexible extrusion force to the drug from above to further protect the drug.

[0033] As an example, the drug storage inner cylinder 1 can be made of food-grade 304 or 316 stainless steel. The selection criteria for the commercially available heat-insulated cup used can be: the inner diameter is between 6.0 - 6.5 cm, the inner height is 16 - 21 cm, and the inner diameters at the bottom and the opening are basically the same, and the heat-insulating effect is good. The height of the drug storage inner cylinder 1 is 15 - 20 cm, the diameter is 2.5 - 3 cm, and the sealing is good to prevent moisture from seeping in.

[0034] Specifically, the middle support ring 3 can be connected to the drug storage inner cylinder 1 through two or more connecting pieces 10. The connecting pieces 10 can be rigid straight rods, and the rigid straight rods can be connected to the drug storage inner cylinder 1 and the middle support ring 3 at both ends by welding, gluing, etc. The space between the drug storage inner cylinder 1 and the middle support ring 3 can be used to fill the refrigeration medium.

[0035] Preferably, the surface of the middle support ring 3 is sprayed with wear-resistant rubber to prevent hard contact with the heat-insulated cup wall.

[0036] Specifically, the bottom fixed disc 4 is a solid flat disc, which plays the role of supporting, fixing and stabilizing the medicine storage inner cylinder 1. The surface is sprayed with wear-resistant rubber material to prevent friction with the inner liner of the thermos cup and cause damage.

[0037] As an example, the diameters of the middle support ring 3 and the bottom fixed disc 4 can be between 5.5 and 6.0 cm.

[0038] The above dimensions are only examples given in this solution. According to actual requirements, they can be defined as other appropriate dimensions.

[0039] When in use, first place the medicine to be stored refrigerated in the medicine storage inner cylinder 1. For medicines with smaller specifications, flexible blocks 7 can be appropriately filled to stabilize and fix the medicines. Then tighten the inner cylinder cover 2 to ensure the sealing of the medicine storage inner cylinder 1. Then vertically insert the medicine storage inner cylinder 1 into a commercially available thermos cup of appropriate size. When inserting, it should be in the way that the bottom fixed disc 4 is downward. Then add a cold source medium into the thermos cup.

[0040] The type of the cold source medium depends on the actual refrigeration requirements, and ice cubes, ice-water mixture, etc. can be used. The added amount can fill the thermos cup as much as possible. Finally, tighten the thermos cup cover. If stored for a long time, the cold source medium can be replaced at intervals according to the actual heat preservation effect of the thermos cup.

[0041] Before use, to ensure the safety of the stored medicine, the sealing test of the medicine storage inner cylinder can be carried out first. The operation method is as follows: empty the medicine storage inner cylinder 1, tighten the inner cylinder cover 2, then vertically insert the medicine storage inner cylinder 1 into a commercially available thermos cup of appropriate size. When inserting, it should be in the way that the inner cylinder cover 2 is upward and the disc base is downward. Then fill the thermos cup with water, tighten the thermos cup, and invert the thermos cup. Observe for 30 minutes or longer. Take out the medicine storage inner cylinder 1, dry all the water remaining on the surface, and unscrew the inner cylinder cover 2. As long as no water enters the medicine storage inner cylinder 1, it can be used safely.
