Description

Technical Field

[0001] The present invention relates to the technical field of medical facilities, and in particular to an automatic disinfection type nucleic acid sampling cabin. Background Art

[0002] With the increasing transmissibility of the novel coronavirus, large-scale screening for the novel coronavirus is currently characterized by large-scale, large-scale testing, localized locations, outdoor testing, and significant climatic influences. Existing COVID-19 sampling methods utilize pharyngeal or nasal swabs. During this process, the subject is susceptible to retching or sneezing due to the foreign body sensation of the swab, producing droplets or aerosols containing large amounts of the virus. These droplets or aerosols can remain suspended in the air or adhere to nearby surfaces, where the virus can survive for a long time. Subsequent healthy subjects can inhale airborne viral droplets or aerosols by removing protective gear such as masks, or by touching objects with their hands, potentially spreading the novel coronavirus. During large-scale screening, time constraints and the airborne nature of the novel coronavirus can make it difficult to find suitable temporary sampling sites in shops or buildings. Therefore, outdoor sampling is often performed in open areas. In these environments, natural weather conditions such as heat, heavy rain, and snow can complicate sampling. The extreme conditions and demanding workload can also put strain on the health of healthcare workers wearing protective gear. At the same time, due to protection requirements, medical workers need to manually spray disinfectant on their hands and desktop environment after completing sampling for each person. The repetitive work increases their fatigue and even leads to occupational diseases.

[0003] Existing nucleic acid sampling cabins usually include a main cabin and a sub-cabin. Both the main cabin and the sub-cabin are closed cabins with a purification air conditioning system for delivering purified air into the cabin and disinfection equipment for disinfecting the cabin environment during rest time. The disadvantages are: (1) Manual opening and closing of the door makes it easy for virus-carrying droplets or aerosols to adhere to the door handle, and the healthy people waiting to be tested behind are infected through contact; (2) The ozone-ultraviolet disinfection device requires a long disinfection time each time, and one medical staff member in the cabin needs to perform disinfection operations in three sub-cabins, which greatly increases the workload of the medical staff, and does not consider reducing unnecessary operations for the medical staff and alleviating their labor and workload; (3) Entering and exiting through the same door increases the probability that droplets or aerosols carried by clothing after sampling are transmitted to the healthy people waiting in line behind. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic disinfection type nucleic acid sampling cabin to solve the problems existing in the above-mentioned prior art and reduce the probability of viral infection during the nucleic acid sampling process.

[0005] To achieve the above-mentioned object, the present invention provides the following solution: The present invention provides an automatic disinfection nucleic acid sampling cabin, comprising:

[0006] A medical cabin, serving as a cabin for accommodating medical workers, wherein an air supply blower, a HEPA filter, and an air inlet at the top of the medical cabin are sequentially connected, and the air supply blower and the HEPA filter are respectively arranged above the medical cabin;

[0007] The sampling cabin is used to accommodate personnel to be sampled and is connected to the medical cabin through a sampling port; an exhaust port is provided on the top of the sampling cabin, and the exhaust port is connected to the air inlet of the exhaust fan; a sampling door is provided on the sampling port, and an entrance door and an exit door are provided on the sampling cabin, and the sampling door, the entrance door and the exit door are all electric doors, and infrared people flow sensors are provided at the entrance door and the exit door; a spray device is also provided on the top of the sampling cabin, and the spray device is connected to the disinfectant storage tank;

[0008] A control unit is used to receive the human flow signals from all the infrared human flow sensors and control the opening and closing of the air supply fan, the exhaust fan, the sampling door, the entrance door, the exit door and the spray device according to the human flow signals.

[0009] Preferably, a seat and a workbench are provided in the medical cabin, and a nucleic acid sampling tool is provided on the workbench; the nucleic acid sampling tool includes an infrared induction disinfectant sprayer.

[0010] Preferably, the medical cabin and the sampling cabin are both provided with disinfection equipment, and the disinfection equipment adopts an ozone disinfector or an ultraviolet disinfector.

[0017] Compared with the prior art, the present invention has achieved the following technical effects:

[0018] The automatic disinfection nucleic acid sampling cabin of the present invention can provide a clean environment for medical workers taking samples and the subjects being tested, reducing the risk of infection for both parties. Especially in the face of large-scale centralized sampling, it can reduce the repetitive work of medical workers and provide a comfortable and safe environment for medical workers and subjects.

[0019] The automatic disinfection nucleic acid sampling cabin of the present invention can form a flow process in which clean air enters from the top of the medical cabin → medical cabin → sampling port → cabin to be sampled → flows out from the top of the cabin to be sampled. Since the medical cabin maintains positive pressure, droplets or aerosols released by the sampled person cannot enter the medical cabin and pollute the cabin environment.

[0020] The spray device in the sampling cabin can be automatically operated during operation to maximize the safety of healthy people to be tested and avoid cross infection. It can also be controlled by medical staff with one button.

[0021] The infrared disinfectant sprayer in the medical cabin facilitates hand disinfection for medical workers, eliminating the repetitive task of manually pressing an alcohol spray bottle after each sample collection, reducing their workload and preventing occupational injuries. Furthermore, because it is an infrared sensing device, there is no risk of contact with contaminated items.

[0022] Infrared crowd flow sensors detect and automatically count the number of people, which can be used as a reference for sample verification, reducing the workload of staff. The flow of people being tested is one-way, preventing droplets or aerosols from re-entering the waiting crowd. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0030] The purpose of the present invention is to provide an automatic disinfection type nucleic acid sampling cabin to solve the problems existing in the above-mentioned prior art and reduce the probability of viral infection during the nucleic acid sampling process.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 4 As shown, this embodiment provides an automatic disinfection nucleic acid sampling cabin 100, including a medical cabin 6, a sampling cabin 1 and a control unit.

[0033] The medical cabin 6 is a cabin for accommodating medical workers. It is equipped with a door 2 for medical workers to enter and exit. The air blower 3, HEPA filter, and air inlet at the top of the medical cabin 6 are connected in sequence. The air blower 3 and HEPA filter are respectively arranged above the medical cabin 6. The medical cabin 6 is equipped with a seat and a workbench, on which nucleic acid sampling equipment is provided. The nucleic acid sampling equipment includes an infrared-sensing disinfectant sprayer 10. When the medical worker extends his hand to the spray port of the infrared-sensing disinfectant sprayer 10, the infrared-sensing disinfectant sprayer 10 can automatically spray disinfectant, facilitating the disinfection of the medical worker's hands and avoiding the repetitive labor of manually pressing the alcohol spray bottle after each sampling, thereby reducing their workload and preventing occupational injuries. Furthermore, because it is an infrared sensing device, the entire process is contactless, avoiding the risk of contamination of items due to contact.

[0034] The sampling cabin 1 is used to accommodate the person to be sampled; it is connected to the medical cabin 6 through the sampling port 8; an exhaust port is provided on the top of the sampling cabin 1, and the exhaust port is connected to the air inlet of the exhaust fan 4; during normal nucleic acid sampling, the air supply fan 3 and the exhaust fan 4 are both turned on, forming a flow process in which clean air enters from the top of the medical cabin 6 → medical cabin 6 → sampling port 8 → sampling cabin 1 → flows out from the top of the sampling cabin 1. Since positive pressure is maintained in the medical cabin 6, droplets or aerosols released by the sampled person cannot enter the medical cabin 6 and pollute the cabin environment.

[0035] A sampling door 9 is provided on the sampling port 8, and an entrance door 5 and an exit door 7 are provided on the sampling cabin 1. The sampling door 9, the entrance door 5 and the exit door 7 are all electric doors, and infrared flow sensors are provided at the entrance door 5 and the exit door 7; the infrared flow sensor at the entrance door 5 is used to detect the number of people entering the sampling cabin 1, and the infrared flow sensor at the exit door 7 is used to detect the number of people leaving the sampling cabin 1. The actual number of people in the sampling cabin 1 can be obtained by calculating the two parameters. A spray device is also provided on the top of the sampling cabin 1, and the spray device is connected to the disinfectant storage tank.

[0036] A display screen for displaying reminder information is provided on the outer wall of the sampling chamber 1 , and the display screen is connected to the control unit signal.

[0037] The control unit receives traffic flow signals from all infrared traffic flow sensors and, based on these signals, controls the air supply fan 3, exhaust fan 4, sampling door 9, entrance door 5, exit door 7, and the opening and closing of the sprinkler system. A control button for manually activating the sprinkler system is located within the medical cabin 6. An operating instrument is also provided within the medical cabin 6, allowing parameters to be set for the control program of the control unit.

[0038] In this embodiment, the control unit is a computer or a PLC programmable controller.

[0039] The working process of the automatic disinfection nucleic acid sampling cabin 100 of this embodiment is as follows:

[0040] Medical workers in the medical cabin 6 operate the instrument to set the sampling of n people and then automatically spray disinfection;

[0041] The person to be sampled enters the sampling cabin 1, and the air supply fan 3 and the exhaust fan 4 are both turned on, forming a flow process of clean air entering from the top of the medical cabin 6 → medical cabin 6 → sampling port 8 → sampling cabin 1 → out of the top of the sampling cabin 1. Since the medical cabin 6 maintains a positive pressure, the droplets or aerosols released by the person to be sampled cannot enter the medical cabin 6 and pollute the cabin environment;

[0042] The control unit receives the flow signals of the infrared flow sensor at the entrance door 5 and the infrared flow sensor at the exit door 7 in real time, and calculates the actual number of people in the sampling cabin 1 based on the two flow signals. When the actual number of people in the sampling cabin 1 reaches n, the control unit closes the entrance door 5 and displays "Cabin disinfection is about to be carried out, please wait" on the display screen; then, the medical workers take nucleic acid samples from the people in the sampling cabin 1 in turn through the sampling port 8, and the people who have completed the nucleic acid sampling leave the sampling cabin 1 through the exit door 7; when the infrared flow sensor at the exit door 7 detects that all n people in the sampling cabin 1 have left the sampling cabin 1, the control unit closes the exit door 7, the sampling door 9, the air supply fan 3 and the exhaust fan 4, and turns on the spray device in the sampling cabin 1 to spray atomized disinfectant to disinfect the clean environment and items for 30 seconds; then the exhaust fan 4 is started to draw the disinfectant droplets out of the room to restore the environment in the sampling cabin 1, and then the entrance door 5, the exit door 7, and the sampling door 9 are opened, and subsequent people to be tested enter to continue testing.

[0043] It should be noted that the entrance door 5 and the exit door 7 in the sampling cabin 1 are arranged opposite to each other, so that the person to be sampled moves in one direction, which can avoid the spread of droplets or aerosols due to droplets or aerosols sticking to their own clothes and then going back to the queueing crowd.

[0044] Both the medical cabin 6 and the sampling cabin 1 are provided with disinfection equipment, which adopts an ozone disinfector or an ultraviolet disinfector. The disinfection equipment is used to disinfect the medical cabin 6 and the sampling cabin 1 when no sampling work is being performed.

[0045] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
