Description

Technical Field

[0001] This utility model relates to the field of drug crystallization equipment, and in particular to a mobile sample protection, isolation and transfer device. Background Technology

[0002] With the rapid development of the pharmaceutical and chemical industries, highly closed production models for highly active and highly allergenic samples have become crucial for ensuring the safety of operators and the environment. Although current closed production systems can handle such samples in semi-closed or completely isolated environments with strict physical isolation measures, the potential risks during sample transfer and storage have not been adequately addressed. On the one hand, the characteristics of highly active and highly allergenic samples expose them to higher risks during transfer and storage. Unlike ordinary samples, these samples can pose a serious threat to the health of operators upon accidental exposure and may also lead to contamination of the experimental environment. On the other hand, environmental factors such as light, temperature, and humidity can adversely affect samples during transfer and storage, leading to changes in their physicochemical properties, including solid-state form, chemical purity, impurity content, and other related properties. Therefore, the management of highly active / highly allergenic samples requires not only attention to the closed nature of the production process but also the development of corresponding preventative measures to address the various potential risks encountered during sample transfer and storage, ensuring operational safety and sample quality.

[0003] In the existing technology, the transfer of highly active and highly allergenic samples can be carried out by either manual transfer or automated transfer robots. However, automated transfer has high investment and maintenance costs and is subject to failure risks, while manual transfer mostly relies on simple closed transfer devices, which have high exposure risks and low efficiency.

[0004] Therefore, there is a need in the field for a mobile sample protection and isolation transfer device that is flexible, has excellent sealing properties, low exposure risk, can prevent internal samples from being affected by environmental factors, and has high transfer efficiency and safety.

[0023] The technical solution of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1

[0025] like Figure 1-2 As shown in the figure, this embodiment illustrates the overall structure of a mobile sample protection and isolation transfer device. The mobile sample protection and isolation transfer device includes a base 3, a main body 1, and an air inlet structure 8. The main body 1 is fixedly installed on the top of the base 3. The main body 1 is made of plastic with a thickness of 0.1-4 cm, which effectively reduces the risk of sample exposure. The main body 1 is semi-transparent brown in color, which can prevent the sample from being affected by factors such as light sources. The outer surface edge is designed with rounded corners, which can reduce accidental damage during personnel operation.

[0026] The main body 1 is provided with multiple limiting plates 7 and horizontal plates 4, and the interior of the main body 1 is divided into multiple accommodating cavities 5 by the limiting plates 7 and horizontal plates 4. The accommodating cavities 5 are used to place the sample to be transferred. The air inlet structure 8 is provided at the bottom rear side of the main body 1. A sealing door 2 is provided on one side of the main body 1. The sealing door 2 is used to completely seal the main body 1.

[0027] Combination Figure 1As can be seen, the limiting plates 7 are arranged horizontally and divide the interior of the main body 1 into multiple small chambers. The horizontal plates 4 are integrally welded to the limiting plates 7 and are arranged vertically between the limiting plates 7, dividing the small chambers and forming multiple receiving cavities 5. In specific implementations, 3-24 receiving cavities 5 can be set, with a cavity height of 1-10 cm, to increase the transfer throughput. A recessed part 6 is provided on the side of the horizontal plate 4 near the closed door 2, and the recessed part 6 is U-shaped.

[0028] A hinge 10 is fixedly installed on one side of the closed door 2, and the closed door 2 is rotatably mounted on one side of the main body 1 via the hinge 10. A handle 11 is fixedly installed on the outer side of the closed door 2. A half-width magnetic attraction device 12 is provided on the side of the closed door 2 that contacts the main body 1. The half-width magnetic attraction device 12 is used to secure the closed door 2 to one side of the main body 1. The half-width magnetic attraction device 12 includes two magnets fixed inside the closed door 2 and the main body 1 respectively. The two magnets attract each other, strengthening the tightness of the closed door 2 and preventing the sample protection isolation transfer device from being easily opened during use.

[0029] The air intake structure 8 includes multiple inert gas inlets, which can be sealed when not in use. Sample transfer in an inert gas environment can isolate moisture and oxygen, effectively preventing sample oxidation or hydrolysis and maintaining sample stability.

[0030] The main body 1 is equipped with multiple temperature and humidity meters 9. In specific implementations, these can be set to digital display temperature and humidity meters 9 to improve the intuitiveness of temperature and humidity readings and avoid the influence of environmental factors such as temperature and humidity on the samples.

[0031] The height of the main body 1 is 10-50 cm, the length of the main body 1 is 5-50 cm, and the width of the main body 1 is 5-50 cm. The appropriate size allows it to freely enter and exit the functional compartments of various types of semi-enclosed or fully enclosed isolators through the partition door.

[0032] Taking the transfer of an X-ray powder diffraction sample plate carrying a highly active / highly sensitizing drug sample as an example, the transfer process of the mobile sample protection and isolation transfer device shown in this embodiment is as follows:

[0033] The operator moves the mobile sample protection and isolation transfer device shown in this embodiment into the functional compartment of the semi-enclosed or fully enclosed isolator through the hatch. Then, the operator lifts the handle 11, opens the sealing door 2, and places the X-ray powder diffraction sample plates containing highly active / highly sensitizing drug samples into the corresponding number of accommodating cavities 5 in sequence, and places them on the horizontal plate 4. Then, the operator closes the sealing door 2, which is tightly sealed to the main body 1 by the half-width magnetic suction device 12, and is connected to the nitrogen filling device through the air intake structure 8. Then, the operator moves the mobile sample protection and isolation transfer device shown in this embodiment out of the functional compartment of the semi-enclosed or fully enclosed isolator through the hatch, completing the sample transfer.

[0034] In summary, the above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
