Technical Field

[0001] This invention relates to the field of isolation operation device technology, and in particular to a combined isolation operation device. Background Technology

[0002] Isolation devices are used to protect the samples being processed, the personnel, and the external environment. Therefore, they must provide a stable and reliable controlled environment while preventing the leakage of toxic and hazardous substances within the isolation device. To provide a stable and reliable controlled environment, isolation devices typically require the installation of high-efficiency particulate air (HEPA) filters to supply clean air, and various sensors, such as temperature and humidity sensors, differential pressure sensors, and particle concentration sensors, to monitor the environment within the isolation device. However, there are numerous safety risks in preventing the leakage of toxic and hazardous substances from within the isolation device, such as the lack of automatic airtightness testing under positive and negative pressure conditions, the inability to automatically detect exhaust HEPA filters, and the inability to guarantee that the disinfection process is always under negative pressure. Furthermore, such equipment is usually customized according to the process flow, resulting in poor flexibility and adaptability. If the operation process changes significantly, it is difficult to carry out structural modifications to adapt to the new process requirements. Summary of the Invention

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] The purpose of this invention is to provide a modular isolation operation device to solve the problems existing in the prior art. It can be flexibly assembled according to the process flow, effectively improving adaptability.

[0016] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-10 As shown, the present invention provides a combined isolation operation device, which adopts a modular design and mainly consists of an operation chamber 1, a transfer chamber 25, a disinfection module, a ventilation and filtration system, an airtightness detection system, a microenvironment monitoring system, and an automatic control system. It can be flexibly combined according to the process flow. At the same time, a multi-functional transfer island 53 is provided to facilitate the addition of process pipelines or sensing devices, which effectively improves adaptability.

[0018] Both the operating chamber 1 and the transfer chamber 25 are placed on the bracket 35. The operating chamber 1 and the transfer chamber 25 are connected to the disinfection module through disinfection pipelines. A transfer door 46 is provided between the operating chamber 1 and the transfer chamber 25. A transparent operating panel is provided on the front of the operating chamber 1 and the transfer chamber 25. The operating panel is equipped with operating gloves. The operating panel is locked by an electromagnetic lock 36 and can be sealed with the operating chamber body. The operator operates the operating chamber 1 and the transfer chamber 25 through the glove hole 34. The operating panel serves as an operating window 33 for the operator to observe.

[0019] The operating compartment 1 and the transfer compartment 25 are each equipped with independent ventilation and filtration systems. Each ventilation and filtration system consists of a supply air filtration system and an exhaust air filtration system. The supply air filtration system comprises, in sequence, a shut-off valve, a blower, and a high-efficiency supply air filter. The exhaust air filtration system comprises a primary exhaust air filter housing 59, a secondary exhaust air filter housing, an exhaust high-efficiency filter 57, and a shut-off valve. The secondary exhaust air filter housing is separately connected to the main body of the combined isolation operating device. Since the operating compartment 1 and the transfer compartment 25 have the same structure, the description of the subordinate operating compartment 1 includes features common to both. The supply air filtration system is installed at the top of the operating compartment 1, supplying air vertically downwards into the compartment. Air within the operating compartment 1 is exhausted from the bottom rear side and then discharged through the exhaust air filtration system. A pipeline connects the supply air filtration system and the exhaust air filtration system, with a bypass shut-off valve in the middle of the pipeline. When the shut-off valves of the supply and exhaust air filtration systems are closed, and the bypass shut-off valve is open, the supply and exhaust air filtration systems are connected, allowing for recirculation ventilation.

[0020] Specifically, automatic shut-off valves 28, 29, 26, and 27 for air supply and exhaust are respectively installed at the top of the operating chamber 1 and the transfer chamber 25. A transfer chamber air supply fan 40 is installed at the bottom of the automatic shut-off valve 26, and the bottom of the air supply fan 40 is the upstream aerosol generation port 41 of the transfer chamber air supply HEPA filter. An upstream aerosol sampling pipe 42 is also installed at the transfer chamber air supply HEPA filter 56 in the transfer chamber 25. Similar to the air supply filtration system of the transfer chamber 25, an operating chamber air supply fan 47 is installed at the bottom of the automatic shut-off valve 28, and the bottom of the operating chamber air supply fan 47 is the upstream aerosol generation port 48 of the operating chamber air supply HEPA filter. An upstream aerosol sampling pipe 49 is also installed at the air supply HEPA filter in the operating chamber 1. On the back of the operating compartment 1 and the transfer compartment 25, corresponding to the blower and the high-efficiency filter, there are fan box airtight doors 37 and filter airtight doors 38.

[0021] Temperature and humidity sensors 11, wind speed sensors 44, and disinfectant concentration sensors 43 are installed inside the operating chamber 1 and the transfer chamber 25. Differential pressure sensors 10 and particle concentration sensors 4 are installed outside the chambers. An automatic control system is installed on one side of the operating chamber 1 and the transfer chamber 25 on the support 35. The automatic control system is used to connect and control the automatic shut-off valves, disinfection modules, ventilation and filtration systems, airtightness detection systems, and microenvironment monitoring systems in the operating chamber 1 and the transfer chamber 25. The control panel 30 displays the current working data of the isolation device. In addition, the automatic control system is also equipped with an emergency stop button 31 and a switch button 32.

[0022] like Figure 7As shown, particulate matter concentration detection: A particle concentration sensor 4 is installed outside the isolator. The particle concentration sensor 4 has multiple air paths. Air path one connects to automatic shut-off valve one 2 and the sampling port inside the chamber in sequence. Air path two connects to automatic shut-off valve two 3 and the aerosol sampling port downstream of the exhaust HEPA filter in sequence. Air path three connects to automatic shut-off valve three 5 and the self-cleaning filter in sequence. Chamber cleanliness detection: First, automatic shut-off valve three 5 opens, and automatic shut-off valves one 2 and two 3 close. The particle concentration sensor 4 begins sampling. At this time, under the action of the self-cleaning filter 6, the particle concentration sensor 4 performs self-cleaning. After self-cleaning, automatic shut-off valve three 5 closes, and automatic shut-off valve one 2 opens to start collecting air inside the chamber and measuring the cleanliness inside the chamber. After the measurement is completed, all automatic shut-off valves close. Exhaust HEPA filter testing: First, automatic shut-off valve 1 (2) opens, while automatic shut-off valves 2 (3) and 3 (5) close. Particle concentration sensor 4 begins sampling to measure the aerosol concentration inside the chamber. After the measurement, automatic shut-off valve 3 (5) opens, and automatic shut-off valves 1 (2) and 2 (3) close. Under the action of the self-cleaning filter 6, particle concentration sensor 4 performs self-cleaning. After self-cleaning, automatic shut-off valve 3 (5) closes, and automatic shut-off valve 2 (3) opens to start collecting air downstream of the exhaust HEPA filter and measuring the aerosol concentration downstream of the filter. After the measurement, all shut-off valves close.

[0023] like Figure 8 As shown, the main chamber and transfer chamber can automatically perform airtightness testing. The operating chamber and the airtight transfer chamber each have two compressed air inlets. Inlet one is connected sequentially to a high-efficiency filter 7, an automatic shut-off valve, and a compressed air pipeline. Inlet two is connected sequentially to a high-efficiency filter 7, an automatic shut-off valve, a vacuum generator 9, and a compressed air pipeline. This system can perform positive pressure and negative pressure airtightness testing. When the automatic shut-off valve of inlet one opens, external compressed air 8 begins to be injected into the operating chamber or airtight transfer chamber. With the other passages in the chamber completely sealed, positive pressure is formed inside the chamber. A differential pressure sensor 10 connected to the chamber monitors the pressure change inside the chamber. The control system can control the opening and closing of the automatic shut-off valve based on the feedback from the differential pressure sensor 10 to control the amount of compressed air injected and thus control the pressure inside the chamber. When performing negative pressure airtightness testing, the automatic shut-off valve of inlet two opens, and the vacuum generator 9 uses compressed air to generate negative pressure, creating negative pressure inside the chamber.

[0024] like Figure 9As shown, the equipment can generate its own disinfectant gas (vapor) to disinfect the main housing, transfer box, and their supply and exhaust HEPA filters. It is equipped with a disinfection module consisting of a disinfectant generator 12, a circulating fan 13, a heater 14, an electrically operated airtight valve, a residue remover 19, an injection pipeline, and a recovery pipeline. The disinfectant injection pipeline connects to the transfer chamber, the operating chamber, and the disinfection bypass 17 between their supply and exhaust HEPA filters. The disinfectant recovery pipeline connects to the transfer chamber and the operating chamber. Electrically operated airtight valves are installed between the disinfectant injection pipeline and the connected housing and disinfection bypass. The recovery pipeline is connected in parallel with the residue remover 19 and is also equipped with an electrically operated airtight valve, and is connected to the circulating fan 13. The circulating fan 13 is connected to the disinfectant generator 12, and the disinfectant generator 12 is connected to the disinfectant injection pipeline.

[0025] The disinfection system can disinfect the interior of the cabin independently, or simultaneously disinfect the cabin and the supply and exhaust HEPA filters. Since cabin interior disinfection is relatively frequent, while supply and exhaust HEPA filters are typically disinfected during terminal disinfection, the independent disinfection system design reduces the frequency of HEPA filter disinfection, effectively extending their service life.

[0026] Disinfection process: Taking the disinfection operation chamber as an example, close the airtight valve of the operation chamber's air supply and exhaust system, open the electric airtight valve 15 and the electric airtight valve 22, start the disinfectant generator 12 and the circulating fan 13, and after disinfection for a certain period of time, close the electric airtight valve 15 and the electric airtight valve 22, turn off the disinfectant generator 12, open the electric airtight valve 3 23 to carry out the residual disinfectant removal process, and when the disinfectant drops to the set concentration, close the electric airtight valve 3 23 and the circulating fan 13, open the airtight valve of the operation chamber's air supply and exhaust system to ventilate.

[0027] When it is necessary to disinfect the operating chamber and its supply and exhaust HEPA filters, close the airtight valves of the operating chamber's supply and exhaust air system, open the electric airtight valves 22 and 44, open the electric airtight valve on the disinfection bypass between the supply and exhaust HEPA filters, start the disinfectant generator 12 and the circulating fan 13, and after disinfection for a certain period of time, close the electric airtight valves 22 and 44, turn off the disinfectant generator 12, open the electric airtight valve 323 to carry out the residual disinfectant removal process, and when the disinfectant concentration drops to the set level, close the electric airtight valve 323 and the circulating fan 13, open the airtight valves of the operating chamber's supply and exhaust air system to ventilate.

[0028] like Figure 10As shown, the main chamber and transfer chamber can automatically depressurize: the automatic depressurization device is installed downstream of the exhaust high-efficiency filter, with a pipeline filter 21 and an automatic depressurization valve 20 installed in sequence. In disinfection mode, the airtight valves of the supply and exhaust systems of the transfer chamber and the operating chamber are closed, and the chamber is in a sealed state. Under normal circumstances, the temperature inside the chamber will rise, and the pressure inside the chamber will rise rapidly as disinfection gas (vapor) is continuously injected. To prevent toxic and harmful substances from leaking into the indoor environment due to positive pressure inside the cabin during disinfection, it is essential to ensure that the cabin is under negative pressure relative to the outside atmosphere throughout the entire disinfection process. Therefore, the automatic pressure relief valve 20 of the automatic pressure relief device is opened simultaneously with disinfection. Since the downstream of the automatic pressure relief valve 20 connects the pipeline between the first-stage and second-stage high-efficiency exhaust air filter, and the second-stage filter is connected to the building's exhaust system, the air passing through the pressure relief device needs to be filtered again by the second-stage filter before being discharged into the building's exhaust system. Furthermore, the exhaust system is always under negative pressure. Therefore, by utilizing the negative pressure suction of the building's exhaust system, rapid depressurization of the sealed cabin can be achieved, maintaining a constant negative pressure state and effectively ensuring operational safety.

[0029] In one embodiment, the operating cabin 1 is provided with a multi-functional transfer island 53: a multi-functional transfer island 53 is provided on one side of the operating cabin 1. The multi-functional transfer island 53 can be quickly and sealed to the operating cabin 1 by snap-fit. The multi-functional transfer island 53 can be equipped with sensors, gas pipelines and liquid pipelines, which can ensure that various accessories that need to be installed through the cabin can be added as needed without compromising the overall airtightness of the operating cabin.

[0030] In one embodiment, both the operating chamber 1 and the transfer chamber 25 are equipped with temperature and humidity sensors 11, differential pressure sensors 10, wind speed sensors 44, disinfectant concentration sensors 43, waterproof sockets, etc., which can monitor the temperature, relative humidity, relative pressure difference, and downward airflow speed in real time. The wind speed sensor 44 is installed on the downwind side of the high-efficiency air filter. At the same time, a camera is installed in the operating chamber 1 to record the operation in real time.

[0031] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.

Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope.
