Description

Technical Field

[0001] The present invention relates to the technical field of temporary storage of medicines, and more specifically, to a low-temperature medicine storage device. Background Art

[0002] In several types of medical drugs such as topical drugs, capsules, and dry powder injections, if the temperature is too high during placement and storage, it will cause the oxidation and hydrolysis reactions of the drug components to accelerate, and will also cause the volatilization of components with low boiling points. In addition, some special dosage forms of drugs (such as suppositories) will change in dosage form under high temperature conditions. In these cases, the efficacy of the drugs is reduced, the drugs deteriorate, and may be accompanied by the production of toxic by-products. Therefore, special care should be taken when storing such drugs, and they must be strictly kept in a specific low-temperature environment to prevent the drugs from deteriorating.

[0003] Currently, low-temperature stored drugs need to undergo manual transportation, drug information verification, patient information verification and other steps after being taken out. These indispensable processes will cause a window period for drug storage, resulting in the drugs still being inevitably exposed to room temperature after being taken out. Especially in summer, the short storage window period will significantly increase the probability of drug deterioration. Even if complete deterioration does not occur, the efficacy of some drugs with high temperature sensitivity will be reduced, thereby affecting subsequent treatment effects. Therefore, it is necessary to provide a temporary storage device for low-temperature drugs to cope with the storage window period after they are taken out. Summary of the invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a low-temperature medicine storage device, which provides a protective film, a double-layer sandwich structure, a cavity protrusion and a concave groove, and utilizes the mutual cooperation of the several. The double-layer sandwich structure cooperates with the protective film to fully wrap the taken medicine tube for protection, thereby keeping its overall internal temperature warm and preventing it from directly contacting the outside air, thereby reducing its heat transfer efficiency and prolonging its low-temperature sustained-release time, thereby avoiding the adverse conditions such as the deterioration of the medicine and the reduction of the efficacy during the window period caused by the existing process, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: a low-temperature medicine storage device, comprising a protective film, a double-layer sandwich structure is arranged on the top of the protective film, the double-layer sandwich structure is divided into two parts, an inner track and an outer track, the lowest horizontal point of the inner track is lower than the lowest horizontal point of the outer track, a cavity protrusion is arranged on the bottom end of the protective film, the cavity protrusion is located at the center of the protective film, and a plurality of deformation notches are evenly opened at the oblique lower side of the outer side of the double-layer sandwich structure; A notch is gradually formed between the deformation notch and one side of the inner wall of the double-layer sandwich structure. The deformation notch gradually expands along a trajectory from the notch to the center, and gradually shrinks and closes along a trajectory from the center to the innermost side. A concave groove is integrally formed at the connection between the protective film and the cavity protrusion, and the concave direction of the concave groove points vertically to the central axis direction of the protective film. A bulge is integrally formed at the bottom end of the concave groove, and a rounded transition is formed between the concave groove and the bulge.

[0006] In a preferred embodiment, the protective film and the double-layer sandwich structure are made of EPDM rubber material.

[0007] In a preferred embodiment, the volume of the concave groove is smaller than the overall volume of the cavity protrusion, and the concave groove is entirely located inside the outer track of the protective film.

[0011] Technical effects and advantages of the present invention: The present invention provides a protective film, a double-layer sandwich structure, a cavity protrusion and a concave groove, and utilizes the mutual cooperation of the several parts. The double-layer sandwich structure cooperates with the protective film to fully wrap the taken out medicine tube, thereby keeping the overall internal temperature of the medicine warm and preventing it from directly contacting the outside air, thereby reducing its heat transfer efficiency and extending its low-temperature sustained-release time, thereby avoiding the adverse conditions such as medicine spoilage, decreased efficacy, etc. during the window period caused by the existing process. Moreover, when the three-dimensional deformable groove as a whole slides toward the inner side of the protective film with the double-layer sandwich structure, the deformable groove is compressed and gradually deformed, thereby utilizing the elastic force generated by the deformation to further cover the double-layer sandwich structure on the top of the medicine tube, thereby completing a more saturated covering protection for the entire medicine tube, and further improving the protection effect on the medicine.

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] As attached Figure 1 To Attachment Fig. 9A low-temperature medicine storage device shown in the figure comprises a protective film 1, a double-layer sandwich structure 2 is arranged on the top of the protective film 1, and the double-layer sandwich structure 2 is divided into two parts, an inner track and an outer track, the lowest horizontal point of the inner track is lower than the lowest horizontal point of the outer track, and a cavity protrusion 3 is arranged on the bottom of the protective film 1, and the cavity protrusion 3 is located at the center of the protective film 1, and a plurality of deformation notches 4 are evenly opened at the oblique lower side of the outer side of the double-layer sandwich structure 2. Through the above arrangement, the double-layer sandwich structure 2 can be used in conjunction with the protective film 1 to fully wrap the taken-out medicine tube for protection, thereby protecting the entire interior of the medicine tube. The temperature is kept warm to prevent it from directly contacting with the outside air, thereby reducing its heat transfer efficiency and prolonging its low-temperature sustained release time, thereby avoiding the adverse conditions such as the drug being spoiled and the drug efficacy being reduced during the window period caused by the existing process. At the same time, the lowest point of the inner track of the double-layer sandwich structure 2 is lower than the lowest point of the outer track, so that the inner track of the double-layer sandwich structure 2 can naturally slide downward along the drug tube as the drug tube moves downward, thereby conforming to the moving direction of the drug tube, and at the same time providing more length margin for the downward movement of the drug tube, further facilitating the fixing operation of the drug tube; A notch is gradually formed between the deformation groove 4 and one side of the inner wall of the double-layer sandwich structure 2. The deformation groove 4 gradually expands along a trajectory from the notch to the center, and gradually shrinks and closes along a trajectory from the center to the innermost side. A concave groove 5 is integrally formed at the connection between the protective film 1 and the cavity protrusion 3. The concave direction of the concave groove 5 points vertically to the central axis direction of the protective film 1. A protrusion 6 is integrally formed at the bottom end of the concave groove 5. There is a rounded transition between the concave groove 5 and the protrusion 6. Through the above arrangement, it can be ensured that when the deformation groove 4 as a whole slides toward the inner side of the protective film 1 as the double-layer sandwich structure 2, the deformation groove 4 is compressed and gradually deformed, thereby utilizing the reverse elastic force generated by its deformation to further cover the double-layer sandwich structure 2 above the drug tube, thereby completing a more saturated covering protection for it, further improving its protection effect, and the degree of adhesion between it and the drug tube.

[0016] The protective film 1 and the double-layer sandwich structure 2 are made of EPDM rubber material throughout. The protective film 1 is distributed in a V-shape from top to bottom as a whole. The outer surface of the protective film 1 is evenly provided with anti-slip granular patterns. The thickness of the protective film 1 and the double-layer sandwich structure 2 are equal. The inner wall of the protective film 1 is smooth. Through the above-mentioned arrangement, when the drug tube gradually slides into the interior of the protective film 1, the protective film 1 is distributed in a V-shaped trajectory, which can be well attached to the outer surface of the drug tube and use its own elastic force after expansion to keep in close contact with it, thereby further improving the firmness of the attachment between the two.

[0017] For details, please refer to the attached manual Figure 2 and attached Figure 8 The volume of the concave groove 5 is smaller than the overall volume of the cavity protrusion 3 , and the concave groove 5 is entirely located within the outer track of the protective film 1 .

[0018] The specific implementation method is as follows: by utilizing the above-mentioned arrangement, when the medicine tube moves downward and is fixed to the inner bottom end of the protective film 1, it can first contact the concave groove 5 above the cavity protrusion 3, thereby preventing it from moving further downward, prompting the operator that the medicine tube has been fixed in place, and providing a certain space for the cavity protrusion 3 below it to prevent it from being in too close contact with the bottom of the medicine tube, thereby facilitating the subsequent sliding of the medicine tube out of the protective film 1.

[0019] For details, please refer to the attached manual Figure 2 -Attached Figure 6 There is a gap between the outer side and the inner side of the double-layer sandwich structure 2, the top of the double-layer sandwich structure 2 forms a semicircular track, the outer track of the double-layer sandwich structure 2 is connected with the top surface of the protective film 1, and the inner track of the double-layer sandwich structure 2 is connected with the inner wall surface of the protective film 1.

[0020] The specific implementation method is as follows: through the above-mentioned arrangement, it is ensured that when the medicine tube slides into the interior of the protective film 1, it can contact the inner track of the double-layer sandwich structure 2 and drive it to slide downward. At this time, the inner and outer tracks of the double-layer sandwich structure 2 will gradually roll toward the inner side of the protective film 1 as the medicine tube goes deeper, thereby ensuring that the initial sliding friction between the double-layer sandwich structure 2 and the medicine tube is transformed into rolling friction, further improving the smoothness of the deep sliding of the medicine tube, thereby improving its flexibility of use.

[0021] Working principle of the present invention: Step 1: First, the operator assembles the device normally, performs aseptic disinfection, and then uses the device normally.

[0022] The second step: first, the operator takes out the medicine tube containing the medicine from the low-temperature environment of the storage room, and inserts it vertically from top to bottom into the interior of the protective film 1 in a vertical posture. During the gradual insertion process, it first contacts the inner track of the double-layer sandwich structure 2 and drives it to slide downward. At this time, the inner and outer tracks of the double-layer sandwich structure 2 will gradually roll toward the inner side of the protective film 1 as the medicine tube goes deeper, thereby ensuring that the initial sliding friction between the double-layer sandwich structure 2 and the medicine tube changes to rolling friction, further improving the smoothness of the deep sliding of the medicine tube. At the same time, during the sliding process, the protective film 1 is continuously stretched to both sides by the volume of the medicine tube. At the same time, the protective film 1 is in a V-shaped distribution shape, so that it can be well attached to the outer surface of the medicine tube, and use its own elastic force after expansion to closely contact with it, further improving the attachment firmness between the two. Finally, when the medicine tube moves downward and is fixed to the inner bottom end of the protective film 1, it can contact the concave groove 5 above the cavity protrusion 3. The tendency of the medicine tube to be pressed inward and deformed is prevented from further moving downward, so as to remind the operator that the medicine tube has been fixed in place, and provide a certain space for the cavity protrusion 3 below it to prevent it from being too closely in contact with the bottom of the medicine tube, so as to facilitate the subsequent sliding of the medicine tube out from the inside of the protective film 1. Subsequently, the operator can carry out a series of subsequent steps such as manual transportation, medicine information verification, and patient information verification. During the verification, the protective film 1 and the double-layer sandwich structure 2 are used to isolate and protect the medicine tube together, so as to avoid the protection window period caused by the existing process, which causes the medicine to spoil, deteriorate, and reduce the efficacy of the medicine. After all the subsequent steps are completed, the cavity protrusion 3 can be pinched and pushed downward, and the double-layer sandwich structure 2 can be gradually turned outward. At this time, the medicine tube can be smoothly slid, and then the medicine tube can be opened, and the medicine can be injected and taken immediately, ensuring the safety of the medicine throughout the process, and ensuring that the medicine is in a protected state isolated from the external environment from beginning to end. Finally, the device completes the insulation process during the window period after the medicine is taken out.

[0023] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.

[0024] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change; Secondly: In the drawings of the embodiments disclosed in the present invention, only the structures related to the embodiments disclosed in the present invention are involved, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present invention can be combined with each other; Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
