Description

Technical Field

[0001] The utility model relates to the technical field of isolation cabins, in particular to a negative pressure isolation cabin. Background Art

[0002] With the discovery of various infectious diseases, the world is paying more and more attention to the technology of preventing and controlling the spread of infectious diseases. At present, air medical transport only focuses on patients with non-infectious diseases, and there is a temporary lack of transport modes and related technical products for infectious diseases. At the same time, international air medical rescue also lacks professional isolation devices. Simple isolation devices cannot effectively block the risk of infection during transport in special environments such as aviation.

[0003] Although foreign research institutions have conducted extensive research on negative pressure isolation cabins that can effectively block the risk of infection during the transfer process, related products are still in the early stages of research and development. Utility Model Content

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the problem that the existing simple isolation device cannot effectively block the risk of infection during the transportation process, and proposes a new negative pressure isolation cabin.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] Specifically, the utility model provides a negative pressure isolation cabin, which is characterized in that the negative pressure isolation cabin includes:

[0007] A main body, the main body comprising a bottom plate and side walls extending upward from the bottom plate;

[0008] a transparent shield detachably attached to an upper edge of a side wall of the main body and configured to be sealingly engaged with the main body to form an isolation cabin for receiving a patient; and

[0009] A bidirectionally adjustable positive and negative pressure valve assembly comprises a first positive and negative pressure regulating device and a second positive and negative pressure regulating device. The first positive and negative pressure regulating device and the second positive and negative pressure regulating device are respectively and sealingly arranged on the side walls of the two ends of the main body along the longitudinal direction of the main body, so as to be connected with the isolation cabin fluid through corresponding through holes formed on the end side walls of the main body, so as to cooperatively regulate the flow direction of the air in the isolation cabin and filter the air passing through the isolation cabin.

In addition, when the extended pull rod is not needed, the pull rod can be retracted to the bottom of the negative pressure isolation cabin for hiding, thereby saving installation and placement space for the isolation cabin.

[0014] According to one embodiment of the utility model, the negative pressure isolation cabin also includes an electric three-stage adjustable bed for accommodating patients, and the electric three-stage adjustable bed can be detachably mounted on the surface of the bottom plate located in the inner cavity of the isolation cabin body.

[0015] The electric three-stage adjustable bed detachably mounted in the isolation cabin can adjust the position and posture of the patient placed on the electric three-stage adjustable bed, so that the patient can be comfortably transferred. Moreover, the electric three-stage adjustable bed can adjust the patient to a posture that is convenient for medical personnel to perform corresponding operations on the patient outside the isolation cabin, so that it is convenient for doctors to monitor, observe and check the patient's condition and take necessary operational measures.

[0016] According to one embodiment of the utility model, the electric three-stage adjustable bed includes three sections connected to each other, and the three sections are configured to be independently adjusted to change the relative position or orientation between each other. By independently adjusting each section, the operator can adjust the position and posture of the patient's body parts such as the knee angle and the backrest height outside the isolation cabin according to the needs or requirements of the patient.

[0017] According to one embodiment of the utility model, the negative pressure isolation cabin also includes a first operating button for adjusting the movement of the electric three-stage adjustable bed, and the first operating button is installed on the wall surface of the main body side wall outside the inner cavity of the isolation cabin body. The operator can appropriately adjust the lying posture of the patient in the isolation cabin body through the first operating button on the main body side wall, thereby facilitating subsequent operations.

[0018] According to one embodiment of the utility model, an operation port for allowing the operator to insert his hand into the isolation cabin is provided on the transparent shield. Through the operation port, the user can perform necessary operations in the isolation cabin without having to enter the isolation cabin, thereby effectively ensuring the safety of the operator.

[0019] According to one embodiment of the utility model, the negative pressure isolation cabin further comprises a cover for sealing the operation port, wherein the cover comprises an elastic protrusion protruding toward the operation port and configured to be closely matched with the operation port. When the operator does not need to perform necessary operations in the isolation cabin, the cover seals the operation port, which can effectively ensure the sealed isolation of the isolation cabin, and only allows the air in the isolation cabin to flow in and out in a set manner.

[0020] According to one embodiment of the utility model, the wall of the operation port is constructed as a sealed interlayer with a space for storing items. Through the interlayer on the wall of the operation port, the operator can place matching medical gloves, garbage bags, food delivery bags and other modular equipment in the interlayer for subsequent use when needed.

[0021] According to an embodiment of the utility model, there are multiple operation ports, and the multiple operation ports are distributed at multiple different positions on the transparent shield to ensure that all parts of the patient's body are contacted. Through the multiple operation ports of the transparent shield, it is ensured that the operator can contact all parts of the patient's body, so that the operator or medical staff can quickly deal with possible emergency situations of the patient.

[0022] According to one embodiment of the utility model, the first positive and negative pressure regulating device and the second positive and negative pressure regulating device respectively include a ventilation device connected to the fluid of the isolation cabin, a filtering device arranged on the outside of the ventilation device and connected to the fluid of the ventilation device, a shell with multiple ventilation holes, and a control module arranged on the shell for controlling the working mode of the ventilation device.

[0023] The ventilation device of the first positive and negative pressure regulating device and the second positive and negative pressure regulating device can adjust the direction of the air flowing into and out of the isolation cabin. The filtering device can filter the air flowing into and out of the isolation cabin to prevent viruses from entering the cabin or spreading to the outside air. The control module can autonomously and controllably adjust the air flowing into and out of the cabin and the direction of air flow, and control the distance between the air to be filtered and the filtering device, thereby ensuring the safety and cleanliness of the air flowing into and out of the isolation cabin.

[0024] According to an embodiment of the utility model, the first positive and negative pressure regulating device and the second positive and negative pressure regulating device further include a display panel arranged on the surface of the housing outside the inner cavity of the isolation cabin, and the display panel is electrically connected to the control module to display the working mode of the corresponding ventilation device. The positive pressure or negative pressure working state in the isolation cabin can be intuitively seen through the display panel, which is convenient for understanding the infection source that needs to be prevented and the condition of the patient.

[0025] According to one embodiment of the utility model, a control panel electrically connected to the control module is provided on the surface of the main body side wall outside the inner cavity of the isolation cabin, and the control panel is configured to send control instructions associated with the working mode to the control module according to user input.

[0026] According to an embodiment of the present invention, the control module is configured to control the working mode of the corresponding ventilation device to be a negative pressure mode or a positive pressure mode.

[0027] In the negative pressure mode, air flows from the outside of the negative pressure isolation cabin into the isolation cabin body after being filtered by the filter device of the first positive and negative pressure regulating device, and then flows out after being filtered by the second positive and negative pressure regulating device.

[0028] Among them, in the positive pressure mode, air flows into the isolation cabin body from the outside of the negative pressure isolation cabin after being filtered by the filter device of the second positive and negative pressure regulating device, and then flows out after being filtered by the first positive and negative pressure regulating device.

[0029] The working mode of the ventilation device is adjusted to generate a positive pressure in the isolation cabin relative to the environment. The air outside the isolation cabin will be sucked into the isolation cabin through the filter device at the patient's feet and the ventilation device, and then inhaled by the patient after a long distance from the feet to the patient's mouth. The air exhaled by the patient will then flow out of the filter device at the head through the exhaust function of the ventilation device at the top of the head. At this time, the air in the external environment can be fully filtered before being breathed in by the patient, thereby protecting vulnerable patients from environmental influences.

[0030] The working mode of the ventilation device is adjusted to make the isolation cabin produce negative pressure relative to the environment. The air outside the isolation cabin will be sucked into the isolation cabin through the filter device at the patient's head through the ventilation device, and then inhaled by the patient after passing through the ventilation device at the top of the head to the patient's mouth. The air exhaled by the patient will then pass through the longer distance from the patient's mouth to the feet, and then flow out from the filter device at the feet through the exhaust function of the ventilation device. In this way, it can ensure that the infectious gas generated by the patient's breathing is fully filtered and purified, thereby protecting the external environment from the influence of infectious patients.

[0031] On the basis of conforming to the common sense in the art, the above-mentioned preferred implementation modes can be arbitrarily combined to obtain the preferred implementation modes of the present utility model.

[0032] The positive and progressive effects of the above-mentioned embodiments of the utility model are:

[0033] 1. By providing an isolation cabin for accommodating patients and isolating them from the outside world, the subsequent transfer of patients can be ensured. Moreover, by adjusting the flow direction of the air in the isolation cabin and filtering the air flowing in and out of the isolation cabin, fresh air can be provided to the patients and the outside environment can be prevented from infecting the patients, or the air in the isolation cabin can be fully filtered when discharged to the outside, thereby avoiding infection to the outside world, providing protection for the safety of medical staff and personnel in the entire transfer process, and thus effectively ensuring the safe transfer of patients;

[0034] 2. By independently adjusting each section of the electric three-stage adjustable bed, the operator can adjust the patient's knee angle and backrest height, head height and tilt angle and other body parts' position, posture and orientation outside the isolation cabin according to needs or patient's requirements, so as to facilitate monitoring of the patient's physical condition in the isolation cabin.

[0035] 3. An operation port is provided on the transparent shield to allow the operator to insert his hand into the isolation cabin.

[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the implementation mode of the present application will be clearly and completely described below in conjunction with the accompanying drawings showing multiple embodiments according to the present application. It should be understood that all other embodiments obtained by ordinary technicians in this field without spending creative work based on the embodiments recorded in the present application will fall within the scope of protection of the present application.

[0046] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those generally understood by technicians in the technical field to which this application belongs; the terms "including" and the like in the specification and claims of this application and the above-mentioned description of the drawings are open-ended terms. Moreover, it should be noted that the orientation or positional relationship indicated by the terms "bottom", "upper", "lower", "inner", "outer" and "longitudinal direction" are based on the orientation or positional relationship shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, and cannot be understood as limiting the utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0047] like Figures 1 to 7 As shown, the utility model provides a negative pressure isolation cabin, which includes a main body 1, a transparent shield 2 and a two-way adjustable positive and negative pressure valve assembly 3. The main body 1 includes a bottom plate 11 and side walls 12 extending upward from the bottom plate 11. The transparent shield 2 can be detachably attached to the upper edge 13 of the side wall 12 of the main body 1 and is configured to be able to be sealed and engaged with the main body 1 to form an isolation cabin for receiving patients.

[0048] The bidirectionally adjustable positive and negative pressure valve assembly 3 comprises a first positive and negative pressure regulating device 31 and a second positive and negative pressure regulating device 32, wherein the first positive and negative pressure regulating device 31 and the second positive and negative pressure regulating device 32 are respectively and sealedly arranged on the side walls 12 at the two ends of the main body 1 along the longitudinal direction of the main body 1, and are connected to the isolation cabin fluid through corresponding through holes formed on the end side walls 12 of the main body 1, so as to cooperatively regulate the flow direction of the air in the isolation cabin and filter the air passing through the isolation cabin.

[0049] The negative pressure isolation cabin can provide an isolation cabin for accommodating patients through the sealed connection between the main body 1 and the transparent protective cover 2, and properly isolate the patients from the outside world, prevent the spread of various viruses carried by the patients and prevent various viral microorganisms outside the isolation cabin from entering the interior, so as to ensure the subsequent transfer of patients.

[0050] Moreover, the first positive and negative pressure regulating device 31 and the second positive and negative pressure regulating device 32 correspond to the positions of the patient's head and feet respectively, and can cooperate to adjust the flow direction of the air in the isolation cabin and filter the air flowing in and out of the isolation cabin accordingly, so as to provide fresh air for the patient and avoid the influence of the external environment on the patient and cause infection, or fully filter the air in the isolation cabin when discharging it to the external environment, thereby avoiding infection to the outside world, providing protection for the safety of medical staff and personnel in the entire transfer process, and thus effectively ensuring the safe transfer of patients.

[0051] like Figure 2 As shown, the main body 1 is in the shape of a boat as a whole, and the length of its bottom plate 12 is longer than the length of a person, and the width is also wider than the width of a person, so that it is convenient to place the patient on the bottom plate. The first positive and negative pressure regulating device 31 and the second positive and negative pressure regulating device 32 are respectively installed in a sealed manner on the side walls 13 at both ends of the main body 1, wherein the first positive and negative pressure regulating device 31 corresponds to the position of the patient's head in the isolation cabin, and the second positive and negative pressure regulating device 32 corresponds to the position of the patient's feet in the isolation cabin, so that the air entering the isolation cabin through the second negative pressure regulating device 32 is inhaled by the patient after passing a distance, or the air exhaled by the patient is discharged by the second positive and negative pressure regulating device 32 after passing a distance.

[0052] Alternatively, if Figure 4As shown, an equipment interface 8 is also provided below the first positive and negative pressure regulating device 31 , and various connecting pipes and wires of the medical equipment can be connected to the patient inside through a row of equipment interfaces 8 .

[0053] like Figures 3 to 7 As shown, an operation port 21 for allowing the operator to insert his hand into the isolation cabin is provided on the transparent shield 2. Through the operation port 21, the user can perform necessary operations in the isolation cabin without having to enter the isolation cabin, thereby effectively ensuring the safety of the operator.

[0054] The negative pressure isolation cabin also includes a cover 22 for sealing the operation port 21, wherein the cover 22 includes an elastic protrusion protruding toward the operation port 21 and configured to be tightly matched with the operation port 21. When the operator does not need to perform necessary operations in the isolation cabin, the cover 22 seals the operation port 21, which can effectively ensure the sealed isolation of the isolation cabin, thereby only allowing the air in the isolation cabin to flow in and out in a set manner.

[0055] Exemplarily, the operation port 21 is cylindrical and is firmly mounted on the transparent shield 2 by means of welding, gluing or other fastening means. The wall of the operation port 21 is formed as a sealed interlayer 24 with a space for storing items. Through the interlayer 24 on the wall of the operation port, the operator can embed modular equipment such as matching medical gloves, garbage bags, and food delivery bags into the interlayer 24 for subsequent use when needed.

[0056] The size of the elastic protrusion of the cover 22 is the same as the aperture size of the operation port 21, the diameter of one end of the cover 22 is larger than the diameter of the elastic protrusion, and a threaded groove is provided at the end, so that the operator can grasp the cover 22 through the threaded groove, thereby squeezing and screwing the elastic concave part into the operation port 21, thereby achieving the sealing of the operation port 21. It should be understood that when necessary, the cover 22 of the operation port 21 can also be removed by rotating, and the operator can use the operation port 21 to perform operations in the isolation cabin.

[0057] There are multiple operation ports 21, and the multiple operation ports 21 are sequentially distributed on multiple sides or multiple different positions of the transparent shield 2 to ensure that all parts of the patient's body are contacted. Exemplarily, the transparent shield 2 has 8 operation ports 21, and these 8 operation ports 21 are arranged on the circumference of the transparent shield 2 in combination with the operation habits of medical staff, so that the operator can contact all parts of the patient's body through these 8 operation ports 21, so that the operator or medical staff can quickly deal with possible emergency situations of the patient.

[0058] like Figures 2 to 4As shown, the main body 1 further includes an upper edge 13, and the transparent shield 2 further includes a lower edge 23, the upper edge 13 and the lower edge 23 overlap each other in shape, and the lower edge 23 can be buckled on the upper edge 13 of the main body 1, so that the transparent shield 2 can be sealed and joined to the main body 1 through the elastic buckle 5 to form an isolation cabin. Figure 1-7 As shown, a plurality of elastic buckles 5 are arranged around the main body 1 to ensure that the transparent shield 2 is sealed and tightly joined to the main body 1. It should be understood that when the elastic buckle 5 is removed from the negative pressure isolation cabin, the transparent shield 2 can be removed from the top of the main body 1.

[0059] When the main body 1 and the transparent protective cover 2 are sealed together to form an isolation cabin capable of accommodating patients, the internal isolation cabin is isolated from the external environment, and gas exchange between the interior of the isolation cabin and the external environment is performed only through the first positive and negative pressure regulating device 31 and the second positive and negative regulating device 32.

[0060] like Figures 1 to 7 As shown, the first positive and negative pressure regulating device 31 and the second positive and negative pressure regulating device 32 respectively include a ventilation device 33 connected to the fluid of the isolation cabin, a filtering device (not shown) arranged on the outside of the ventilation device 33 and connected to the fluid of the ventilation device 33, an outer shell 34 with a plurality of ventilation holes 35, and a control module (not shown) arranged on the outer shell 34 for controlling the working mode of the ventilation device 33.

[0061] Optionally, the first positive and negative pressure regulating device 31 and the second positive and negative pressure regulating device 32 further include a display panel (not shown) arranged on the surface of the housing 34 outside the isolation cabin, and the display panel is electrically connected to the control module to display the working mode of the corresponding ventilation device 33. The positive pressure or negative pressure working state in the isolation cabin can be intuitively seen through the display panel, which is convenient for understanding the infection source that needs to be prevented and the condition of the patient.

[0062] like Figure 1 and 6 As shown, the side wall 12 of the main body 1 is provided with a control panel 7 electrically connected to the control module on the surface outside the isolation cabin, and the control panel 7 is configured to send a control instruction associated with the working mode of the ventilation device 33 to the control module according to the user's input. The control module is configured to control the working mode of the corresponding ventilation device 33 to be a negative pressure mode or a positive pressure mode.

[0063] Among them, in the negative pressure mode, the ventilation device 33 of the first positive and negative pressure regulating device 31 is used as an exhaust device, and the ventilation device 33 of the second positive and negative pressure regulating device 32 is used as an exhaust device, and the isolation cabin is in a negative pressure state relative to the environment. At this time, the second air flows into the isolation cabin from the outside of the negative pressure isolation cabin after being filtered by the filter device of the first positive and negative pressure regulating device 31 and is inhaled by the patient. Subsequently, the air exhaled by the patient or the air in the isolation cabin will flow a distance to the patient's feet, and will be discharged after passing through the ventilation device 33 of the second positive and negative pressure regulating device 32 and being filtered by the corresponding filter device. At this time, the patient in the isolation cabin can be a patient infected with an infectious disease, and the second positive and negative pressure regulating device 32 can fully filter and purify the infectious gas generated by the patient through breathing, thereby protecting the external environment from the invasion of infectious patients.

[0064] Among them, in the positive pressure mode, the ventilation device 33 of the first positive and negative pressure regulating device 31 is used as an exhaust device, and the ventilation device 33 of the second positive and negative pressure regulating device 32 is used as an exhaust device, and the isolation cabin is in a positive pressure state relative to the environment. At this time, the second air enters the isolation cabin from the outside of the negative pressure isolation cabin through the filtering device of the second positive and negative pressure regulating device 32, and flows for a distance before reaching the patient's head position and being inhaled by the patient. Subsequently, the air exhaled by the patient or the air in the isolation cabin reaches the patient's head position, passes through the ventilation device 33 of the first positive and negative pressure regulating device 31 and is discharged after being filtered by the corresponding filtering device.

[0065] At this time, the patients in the isolation cabin can be general patients who are not infected with infectious diseases. The air enters the isolation cabin from the second positive and negative pressure isolation device at the foot position, and is breathed in by the patients only after the ambient air is fully filtered, which can protect vulnerable patients such as critically ill patients from environmental influences.

[0066] The ventilation device 33 of the first positive and negative pressure regulating device 31 and the second positive and negative pressure regulating device 32 can adjust the direction of the air flowing into and out of the isolation cabin. The filtering device can filter the air flowing into and out of the isolation cabin to prevent viruses from entering the cabin or spreading to the outside air. The control module can autonomously and controllably adjust the air flowing into and out of the cabin and the direction of air flow, and control the distance between the air to be filtered and the filtering device, thereby ensuring the safety and cleanliness of the air flowing into and out of the isolation cabin.

[0067] The working mode of the ventilation device 33 is adjusted so that the isolation cabin generates a positive pressure relative to the environment. The air outside the isolation cabin will be sucked into the isolation cabin through the filter device at the patient's feet through the ventilation device 33, and then inhaled by the patient after passing through the long distance from the feet to the patient's mouth. The air exhaled by the patient will then flow out of the filter device at the head through the exhaust function of the ventilation device 33 at the top of the head. At this time, the air in the external environment can be fully filtered before being breathed in by the patient, thereby protecting vulnerable patients from environmental influences.

[0068] The working mode of the ventilation device 33 is adjusted so that the isolation cabin generates a negative pressure relative to the environment. The air outside the isolation cabin will be sucked into the isolation cabin through the filter device at the patient's head through the ventilation device 33, and then inhaled by the patient after passing through the ventilation device 33 at the top of the head to the patient's mouth. The air exhaled by the patient or the air in the isolation cabin will then pass through the longer distance from the patient's mouth to the feet, and then flow out from the filter device at the feet through the exhaust function of the ventilation device 33. In this way, it can be ensured that the infectious gas generated by the patient's breathing is fully filtered and purified, so that the external environment can be protected from the influence of infectious patients.

[0069] Optionally, consider the patient's comfort and monitoring convenience, such as Figure 5 and 6 As shown, the negative pressure isolation cabin also includes an electric three-stage adjustable bed 6 for accommodating patients, and the electric three-stage adjustable bed 6 can be detachably mounted on the surface of the bottom plate 11 located in the isolation cabin. In addition, the electric three-stage adjustable bed 6 is connected to the bottom plate 12 of the main body 1 through a support rod so that it can move relatively. The technology for detachable installation, the aforementioned connection and movement is relatively mature, so it will not be repeated here.

[0070] like Figure 6 As shown, the electric three-section adjustable bed 6 includes three sections connected to each other, namely, a first section 61 for accommodating the patient's head, a second section 62 for accommodating the patient's chest and abdomen, and a third section 63 for accommodating the patient's legs. The three sections are configured to be independently adjustable to change the relative position or orientation between each other. By independently adjusting each section, the operator can adjust the patient's knee angle, backrest height, head height and tilt angle outside the isolation cabin according to demand or the patient's requirements, thereby changing the position, posture, etc. of the patient's body parts.

[0071] Optionally, the negative pressure isolation cabin further includes a first operating button 71 for adjusting the movement of the electric three-stage adjustable bed 6, and the first operating button 71 is integrated in the control panel 7. Optionally, the first operating button 71 can also be separately installed on the wall surface of the side wall 12 of the main body 1 outside the inner cavity of the isolation cabin. The operator can appropriately adjust the lying posture of the patient in the isolation cabin through the first operating button 71 on the side wall 12 of the main body 1, so as to facilitate subsequent operations.

[0072] The electric three-stage adjustable bed 6 detachably mounted in the isolation cabin can adjust the position and posture of the patient placed on the electric three-stage adjustable bed 6, so that the patient can be comfortably transferred. Moreover, the electric three-stage adjustable bed 6 can adjust the patient to a posture that is convenient for medical personnel to perform corresponding operations on the patient outside the isolation cabin, so that it is convenient for doctors to monitor, observe, and check the patient's condition and take necessary operational measures.

[0073] It should be understood that the electric three-stage adjustable bed 6 here can also be replaced with a stretcher dedicated to the negative pressure isolation cabin. The weight of the emergency stretcher dedicated to the negative pressure isolation cabin is not more than 8Kg, and the maximum load of the stretcher is 150Kg. At this time, the weight of the negative pressure isolation cabin is not more than 60Kg, and the maximum load is 150Kg (including equipment).

[0074] Alternatively, if Figure 1 and 7 As shown, the negative pressure isolation cabin also includes a moving device 4 for moving the negative pressure isolation cabin, the moving device 4 can be detachably arranged on the surface of the bottom plate 11 outside the inner cavity of the isolation cabin, and the moving device 4 includes a plurality of rollers 41, and the plurality of rollers 41 are configured to be able to rotate through rollers 42 under the drive of a motor or manually.

[0075] like Figure 7 As shown, the mobile device 4 also includes a retractable rod 42, which is mounted on the surface of the bottom plate outside the inner cavity of the isolation cabin, and a plurality of rollers 41 are evenly arranged on the lower surface of the retractable rod 42. The rollers 41 are connected to the retractable rod 42, so that the entire negative pressure isolation cabin can be slidably and electromagnetically fixed on the track.

[0076] The negative pressure isolation cabin can be extended and retracted as needed through the retractable rod 42 of the moving device 4, so that the operator can operate and move the negative pressure isolation cabin, and move the negative pressure isolation cabin to a high place such as a medical bed or an airplane through the extended retractable rod 42 as needed. In addition, when the extended retractable rod 42 is not needed, the retractable rod 42 can be retracted to the bottom of the negative pressure isolation cabin for hiding, thereby saving the installation and placement space of the negative pressure isolation cabin.
