Technical Field
[0001] This utility model relates to the field of medical equipment manufacturing technology, and in particular to a double-drawer type cold chain vaccine dispensing device. Background Technology
[0002] With the increasing public awareness of disease prevention, vaccination plays an increasingly important role in the disease control system. To ensure the effectiveness and safety of vaccines, cold chain management throughout the entire process from production and transportation to storage has become a crucial link. Furthermore, at the final stage of vaccination—at medical institutions or vaccination sites—vaccines must also be stored in a specified low-temperature environment (e.g., conventional vaccines need to be kept at 2–8°C) until they are removed just before vaccination.
[0003] Currently, most vaccination institutions still use the traditional manual operation mode for vaccine retrieval. Before vaccination, medical staff need to frequently enter the cold storage to manually retrieve the vaccine. However, this has many drawbacks, specifically: 1) Frequent opening and closing of the cold storage door can cause temperature fluctuations inside the storage, creating temperature breaks and disrupting the stable low-temperature environment for vaccine storage, thus affecting vaccine quality; 2) The manual retrieval process lacks effective information management methods, making it difficult to accurately record and monitor vaccine entry and exit information in real time, increasing the difficulty of vaccine traceability and inventory management; 3) The cold storage is in a low-temperature environment for a long time, and frequent entry and exit by medical staff can easily cause harm to their health.
[0004] While some existing technologies aim to optimize vaccine dispensing processes, such as highly automated vaccine storage devices, have emerged, their structural designs do not adequately consider the needs of temporary vaccine storage and cannot guarantee a strict cold chain environment during dispensing, posing a risk of vaccine exposure to unsuitable temperatures. Therefore, it is urgent for technical personnel to address these issues. Utility Model Content
[0005] This utility model discloses a double-drawer-type cold chain vaccine dispensing device that can realize the entire cold chain, automatic vaccine dispensing, and has a temporary vaccine storage function, in order to solve the problems existing in the prior art and thus improve the safety, standardization and efficiency of vaccination.
[0006] To address the aforementioned technical problems, this utility model relates to a double-drawer-type cold chain vaccine dispensing device, which is integrated into a vaccine cold storage unit and serves as a transit point for cold chain vaccines between vaccine shelves and medical personnel administering vaccines. The double-drawer-type cold chain vaccine dispensing device includes a support frame, a vaccine dispensing drawer, and a vaccine temporary storage drawer. Both the vaccine dispensing and temporary storage drawers are assembled based on the support frame and are arranged in an upper and lower layered manner. In the non-operating state, both the vaccine dispensing and temporary storage drawers remain closed, allowing ready-to-use vaccines and surplus deferred-use vaccines to be stored in an independent low-temperature environment. In the operating state, ready-to-use vaccines are supplied to medical personnel via the vaccine dispensing drawer, while surplus deferred-use vaccines are temporarily stored via the vaccine temporary storage drawer.
[0007] As a further improvement to the technical solution disclosed in this utility model, the Miao storage drawer and the Miao temporary storage drawer have the same design structure. The Miao storage drawer includes a drawer body and a guide assembly. The guide assembly is composed of a guide rail and a guide slider. The guide rail uses the drawer body as its mounting base. The guide slider uses a support frame as its mounting base. Furthermore, during the process of the drawer body being pulled, a sliding friction mechanical relationship is formed between the guide rail and the guide slider.
[0008] As a further improvement to the technical solution disclosed in this utility model, the bottom wall and side wall of the drawer body are provided with multiple heat dissipation and ventilation holes.
[0009] As a further improvement to the technical solution disclosed in this utility model, the double-drawer type cold chain vaccine dispensing device also includes a fluid drive device. The fluid drive device uses a support frame as its mounting base and is located below the vaccine storage drawer.
[0010] As a further improvement to the technical solution disclosed in this utility model, the Miao cashier drawer also includes an electromagnetic lock. The electromagnetic lock uses a support frame as its mounting base. After the drawer body is pushed into place, it is locked in position due to the locking force from the electromagnetic lock.
[0011] As a further improvement to the technical solution disclosed in this utility model, the Miao cashier drawer also includes a spring-assisted device. During the process of the drawer body being pushed in, the spring-assisted device simultaneously stores elastic potential energy. When the electromagnetic lock is unlocked, the spring-assisted device releases the elastic potential energy, and the drawer body springs open automatically due to the elastic restoring force.
[0012] As a further improvement to the technical solution disclosed in this utility model, the Miao storage drawer also includes an insulation board. The insulation board is attached to and fixed to the front side wall of the drawer body.
[0013] In practical applications, the double-drawer type cold chain vaccine dispensing device disclosed in this utility model can achieve at least the following beneficial technical effects, specifically:
[0014] 1) The double-layer drawer-type cold chain vaccine dispensing device is integrated into the vaccine cold storage. Both the dispensing and temporary storage drawers are tightly closed when not in use, creating a completely sealed, low-temperature space within the storage chamber. This prevents the intrusion of large amounts of external heat and avoids temperature fluctuations caused by frequent opening of the cold storage door, effectively eliminating temperature breaks and ensuring that the vaccine remains within the prescribed cold chain environment throughout the entire process of storage, retrieval, and temporary storage.
[0015] 2) The vaccine dispensing drawer and the vaccine temporary storage drawer are arranged in a two-tiered layout, enabling precise classification and management of vaccines. The dispensing drawer is specifically used to store vaccines awaiting administration. When in operation, it can quickly respond to vaccination needs and efficiently deliver vaccines to vaccination medical staff. The vaccine temporary storage drawer is used to temporarily store multiple doses of vaccines or surplus vaccines that have not been used after being retrieved. This not only makes vaccine management more organized but also significantly improves the efficiency of vaccine retrieval and temporary storage during the vaccination process.
[0016] 3) Throughout the vaccination process, the vaccine can be retrieved and temporarily stored by simply opening and closing the drawer, and the vaccination medical staff do not need to enter the cold storage, which helps to ensure the health of the vaccination medical staff.

Detailed Implementation
[0027] In the description of this utility model, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] It is known that the vaccine cold chain supply system is mainly used to ensure that vaccines are kept in a specified low-temperature environment throughout the entire process from storage to administration, thereby ensuring the effectiveness and safety of vaccines.
[0029] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , Figure 2 The diagrams show two different perspectives of the vaccine cold chain supply system disclosed in this utility model. It can be seen that it mainly consists of several parts, including a cold storage room 1, vaccine shelves 2, and a double-drawer-type cold chain vaccine dispensing device 3. The cold storage room 1 serves as the core space for vaccine storage, providing a stable low-temperature environment for the vaccines. The vaccine shelves 2 are located inside the cold storage room 1 and are used to store large quantities of vaccines in a categorized manner. The double-drawer-type cold chain vaccine dispensing device 3 is entirely integrated into the cold storage room 1, serving as a crucial intermediate link between the vaccine shelves 2 and the medical personnel administering the vaccines.
[0030] like Figure 3 , Figure 4As shown, the double-drawer type cold chain vaccine dispensing device 3 is assembled based on the vaccine shelf 2 and is adjacent to the cold storage panel of the cold storage 1.
[0031] Figure 5 , Figure 6 The diagrams show two different perspectives of the double-layer drawer-type cold chain vaccine dispensing device disclosed in this utility model. It can be seen that it mainly consists of a support frame 31, a vaccine dispensing drawer 32, and a vaccine temporary storage drawer 33. Both the vaccine dispensing drawer 32 and the vaccine temporary storage drawer 33 are assembled based on the support frame 31 and are arranged in an upper and lower layered manner. In the non-operating state, both the vaccine dispensing drawer 32 and the vaccine temporary storage drawer 33 remain closed, allowing ready-to-use vaccines and excess vaccines to be stored in an independent low-temperature environment. In the operating state, ready-to-use vaccines are supplied to vaccination medical personnel via the vaccine dispensing drawer 32, while excess vaccines are temporarily stored via the vaccine temporary storage drawer 33.
[0032] When vaccines are needed, a robotic arm inside the cold storage transfers the vaccines from the shelf to the vaccine dispensing drawer 32. Medical personnel can then directly retrieve the vaccines from drawer 32 to administer the vaccination. If there are multiple doses of vaccines or surplus vaccines that have not been used after being removed, medical personnel can place them in the temporary storage drawer 33. Once closed, the temporary storage drawer 33 automatically maintains a low-temperature storage environment to ensure vaccine quality.
[0033] By adopting the above technical solution, on the one hand, the double-layer drawer-type cold chain vaccine dispensing device 3 is entirely built into the cold storage 1, and the vaccine dispensing drawer 32 and the vaccine temporary storage drawer 33 are tightly closed when not in operation, which helps to form a completely sealed low-temperature space in its storage cavity. In this way, the occurrence of large-scale intrusion of external heat is prevented, and temperature fluctuations caused by frequent opening of the cold storage door are avoided, effectively eliminating temperature breakpoints, so that the vaccine is always within the prescribed cold chain environment throughout the entire process of storage, retrieval, and temporary storage. On the other hand, throughout the entire vaccination process, the vaccine retrieval and temporary storage operations can be completed by opening and closing the vaccine dispensing drawer 32 and the vaccine temporary storage drawer 33, and the medical staff administering the vaccine do not need to enter the cold storage, which helps to ensure their health.
[0034] It should also be noted that the layered arrangement of the vaccine dispensing drawer 32 and the vaccine temporary storage drawer 33 enables precise classification and management of vaccines. The dispensing drawer 32 is specifically designed to store vaccines awaiting administration, allowing for rapid response to vaccination needs and efficient delivery of vaccines to healthcare workers during operation. The temporary storage drawer 33, on the other hand, is used to temporarily store multiple doses of vaccines or surplus vaccines that have not been used after being retrieved. This not only makes vaccine management more organized but also significantly improves the efficiency of vaccine retrieval and temporary storage during the vaccination process.
[0035] Furthermore, by Figure 5 , Figure 6 As can also be clearly seen in the diagram, the seedling cashier drawer 32 and the seedling temporary storage drawer 32 have the same design structure and are assembled with the support frame 31 in the same way.
[0036] To save space, this explanation will only use Miao's cashier drawer 32 as an example. Figure 7 , 8 As shown, the drawer 32 mainly consists of a drawer body 321, a guide assembly 322, and an electromagnetic lock 323. The guide assembly 322 is composed of a guide rail 3221 and a guide slider 3222. The guide rail 3221 uses the drawer body 321 as its mounting base, while the guide slider 3222 uses a support frame 31 as its mounting base. During the process of pulling the drawer body 321, a low-resistance sliding friction mechanical relationship is formed between the guide rail 3221 and the guide slider 3222. The electromagnetic lock 323 uses the support frame 31 as its mounting base. After the drawer body 321 is pushed into place, it is locked in position by the locking force from the electromagnetic lock 323. By adopting the above technical solution, the guide assembly 322 provides precise guidance for the drawer body 321, ensuring its stability and orientation during the pulling process.
[0037] More importantly, once the drawer body 321 is pushed into place, the electromagnetic lock 323 can quickly apply a locking force to lock it, ensuring that it remains stable and does not move when not in use, which can effectively prevent the accidental exposure of vaccines to non-cold chain environments.
[0038] Furthermore, similarly Figure 7 , Figure 8 As shown, multiple ventilation holes are evenly distributed on the bottom and side walls of the drawer body 321. A fan 34 is also installed below the vaccine storage drawer 22. The fan 34 is also fixed to the support frame 31. Thus, the even distribution of ventilation holes effectively promotes air circulation within the drawer body 321 during vaccine storage. The fan 34 further accelerates the circulation of cold air within the drawer body 321, preventing uneven temperature distribution caused by poor air circulation and ensuring that the temperature in all areas of the drawer body 321 remains within the 2-8°C cold chain range required for vaccine storage.
[0039] To further improve the insulation performance of the seedling storage drawer 32, such as Figure 7 , Figure 8 As shown, the Miao storage drawer 32 is also equipped with an insulation board 324. The insulation board 324 is attached to and fixed to the front side wall of the drawer body 321. Figure 1 , Figure 2As shown, the insulation board 324 faces the external environment directly and is a key component for heat exchange. The insulation board 324 is preferably made of a material with extremely low thermal conductivity, such as polyurethane foam or vacuum insulation board. This effectively blocks external heat from entering the drawer body 321, effectively reducing the impact of ambient temperature fluctuations on vaccine storage temperature.
[0040] Finally, it should be noted that traditional drawer opening requires entirely manual pulling, which is quite strenuous, especially when frequently retrieving vaccines, inevitably increasing the workload of vaccination staff. Therefore, as a further optimization of the above technical solution, the vaccine dispenser drawer 32 is also equipped with a spring-assisted device (not shown in the figure). During the process of pushing the drawer body 321 in, the spring-assisted device simultaneously stores elastic potential energy. When the electromagnetic lock 323 unlocks, the spring-assisted device releases the elastic potential energy, and the drawer body 321 springs open automatically due to the elastic restoring force.
[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
