Description

Technical Field

[0001] This application relates to the field of pharmaceutical production, and in particular to a temperature and humidity control isolation device. Background Technology

[0002] A cleanroom is a well-sealed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as needed. Cleanrooms are classified into Class A, Class B, Class C, and Class D.

[0003] In the production of API (active pharmaceutical ingredient) raw materials, the material weighing and packaging processes often have high environmental requirements. Therefore, the production of API raw materials needs to be carried out in a Class D cleanroom.

[0004] However, for frequent operations, personnel spend a long time entering and exiting the clean area, and the changing process is cumbersome; there may even be cross-contamination issues during the process of personnel entering and exiting. Utility Model Content

[0005] In order to reduce the number of times personnel enter and exit the cleanroom, thereby improving efficiency and reducing cross-contamination, this application provides a temperature and humidity control isolation device.

[0006] This application provides a temperature and humidity controlled isolation device, which adopts the following technical solution:

[0007] A temperature and humidity controlled isolation device includes a weighing isolation device and a common regulating device. The weighing isolation device includes three chambers. The side walls of each chamber are equipped with gloves that can be inserted into the chamber. Each chamber has a quick-opening, sealed door for attaching gloves. The chambers are sequentially a transfer chamber, a buffer chamber, and an operating chamber. A self-cleaning fresh air system is installed inside each chamber. The common regulating device includes a pressure regulating component to ensure positive pressure in each of the transfer chamber, buffer chamber, and operating chamber.

[0008] By adopting the above technical solution, when staff need to weigh or package materials, they can place the materials inside the chamber and operate them directly while wearing gloves, reducing direct contact between staff and materials. The transfer chamber, buffer chamber, and operating chamber are in a slightly positive pressure state, which makes the internal air pressure higher than the external environment, effectively preventing external air from directly entering the chamber. Furthermore, the pressure in the transfer chamber, buffer chamber, and operating chamber increases progressively, ensuring the airflow direction within the three chambers and reducing the entry of contaminants from the transfer chamber into the buffer chamber and from the buffer chamber into the operating chamber. This eliminates the need for staff to frequently enter and exit the clean area, improving efficiency and reducing cross-contamination, thereby enhancing the cleanliness of the weighing isolation device.

[0009] Optionally, the pressure regulating assembly includes a blower, an inlet pipe, and an outlet pipe. One end of the inlet pipe is located at the outlet of the blower, and the other end of the inlet pipe is sealed. The inlet pipe has three branch inlet pipes, which are respectively connected to three compartments. One end of the outlet pipe is sealed, and the outlet pipe has three branch outlet pipes, which are respectively connected to three compartments. Both the inlet and outlet branch pipes are equipped with air valves to control the air volume.

[0010] By adopting the above technical solution, the pressure regulating component is used to regulate the pressure in the transfer chamber, buffer chamber and operating chamber, the blower is used to supply air to the transfer chamber, buffer chamber and operating chamber, the air inlet pipes send fresh air into the transfer chamber, buffer chamber and operating chamber respectively, the air in the transfer chamber, buffer chamber and operating chamber can enter the air outlet pipe from the air outlet pipe and be discharged to the outside, the air valve can control the air volume entering the chamber and the air volume exiting the chamber, thereby realizing the control of the air pressure in the chamber.

[0011] Optionally, the common regulating device includes a temperature regulating component, which includes a cooling and heating unit, a front cooling section, a rear heating section, and a connecting pipe. The front cooling section is used to introduce fresh air. The two ends of the connecting pipe are respectively connected to the front cooling section and the rear heating section. The rear heating section is connected to the air inlet of the blower. The cooling and heating unit is used to heat the cold water flowing out of the front cooling section and introduce it into the rear heating section, and to cool the hot water flowing out of the rear heating section and introduce it into the front cooling section.

[0012] By adopting the above technical solution, the temperature regulation component is used to regulate the temperature of the airflow entering the cabin. The integrated cooling and heating unit introduces cold water into the front cooling section, which lowers the temperature of the fresh air entering the front cooling section, causing the moisture in the fresh air to condense and achieve dehumidification. Then, the fresh air enters the rear heating section through the connecting pipe. The integrated cooling and heating unit then introduces hot water into the rear heating section, which reheats the fresh air and increases its temperature, thereby achieving temperature and humidity control and regulation within the cabin.

[0013] Optionally, the common regulating device further includes a primary and secondary filter and a high-efficiency filter. The primary and secondary filter is used to filter the fresh air introduced into the front cooling zone, and the high-efficiency filter is used to filter the fresh air discharged from the air outlet of the blower.

[0014] By adopting the above technical solution, the primary and secondary filters are used to perform initial filtration of the fresh air entering the front cooling section, reducing the entry of larger dust particles. After the fresh air is heated, it undergoes secondary filtration through the high-efficiency filter to filter out even finer particles or suspended matter, thereby ensuring the purity of the air entering the cabin.

[0015] Optionally, the common regulating device includes a dehumidifier, which is mounted on the connecting pipe.

[0016] By adopting the above technical solution, when there is a high requirement for humidity inside the cabin, a dehumidifier can be installed on the connecting pipe. The dehumidifier can further dehumidify the air in the surface cooling section to ensure that the humidity in the air meets the cabin requirements.

[0017] Optionally, the cabin is provided with a mounting component for installing gloves. The mounting component includes a mounting ring seat and a flexible O-ring. The mounting ring seat has two annular grooves. The wrist opening of the glove is fitted onto the mounting ring seat and secured into the annular grooves by the flexible O-ring.

[0018] By adopting the above technical solution, the gloves need to be replaced regularly. When the gloves need to be replaced, the gloves to be replaced are moved to the annular slot away from the side wall of the cabin through the opposite set of gloves. Then, the new gloves are sent into the cabin and the wrist and mouth sleeves of the new gloves are set into the annular slot near the side wall of the cabin. Then, they are snapped on by the elastic O-ring. Finally, the gloves to be replaced are removed.

[0019] Optionally, the cabin is provided with a control component for controlling the opening and closing of the sealed hatch. The control component includes a hinge and a hydraulic linkage. One end of the hinge is located on the cabin, and the other end of the hinge is located on the sealed hatch. One end of the hydraulic linkage is located on the cabin, and the other end of the hydraulic linkage is located on the sealed hatch. When the sealed hatch is in the open state, the hydraulic linkage is in a self-locking state.

[0020] By adopting the above technical solution, the hinge enables the rotation operation of the sealed compartment door. When the staff needs to open the sealed compartment door, they can simply rotate it, which is convenient and improves work efficiency. When the sealed compartment door is in the open state, the hydraulic linkage is in a self-locking state, thereby reducing the occurrence of the sealed compartment door rotating randomly during the operation of the staff and providing personal protection for the operator.

[0021] Optionally, the cabin is equipped with ultraviolet disinfection lamps.

[0022] By adopting the above technical solution, ultraviolet disinfection lamps are used to disinfect the cabin, eliminate harmful microorganisms in the environment, and reduce the occurrence of cross-contamination.

[0023] Optionally, the sidewall of the transfer chamber is provided with a continuous bag.

[0024] By adopting the above technical solutions, continuous bags can be used for the closed transfer of raw materials and hazardous gaseous substances, which can reduce the risk of aseptic control and reduce harm to personnel and pollution to the environment.

[0025] Optionally, the three compartments are interconnected, and isolation doors are provided between the compartments to isolate them from each other. The isolation doors are locked and sealed by sealing locks.

[0026] By adopting the above technical solution, the isolation doors achieve relative independence of each compartment, maintain a relatively clean space, and can also be opened by sealing locks to enable the smooth movement of materials within the compartments.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The weighing isolation device is divided into a transfer chamber, a buffer chamber, and an operating chamber. Each chamber is equipped with gloves that can be inserted into the chamber. A common regulating device is used to regulate the pressure, temperature, and humidity inside the chamber.
