Description

Technical Field

[0001] This utility model relates to the field of mobile cabin technology, specifically to a modular medical rescue mobile cabin system. Background Technology

[0002] Currently, nuclear technology is widely used in nuclear industry, military, health, scientific research and other fields, and radioactive materials are normally kept in shielded and strictly managed environments. However, in the event of a nuclear accident or nuclear attack, radioactive materials will spread, leading to radioactive contamination of people and the environment, and causing radiation damage to a certain area of ​​the population.

[0003] In related technologies, decontamination cabins or tents are typically deployed on-site to conduct emergency decontamination of ordinary personnel before they are sent to medical institutions for further medical treatment. While this medical rescue method can prevent personnel from being continuously exposed to radiation, it lacks reasonable classification of personnel and is not conducive to targeted rescue. In addition, there is a lack of on-site decontamination and emergency treatment rescue platforms for severely injured or bedridden patients. Utility Model Content

[0004] In view of this, the present invention provides a modular medical rescue cabin system to solve the problem that existing medical rescue methods are not conducive to targeted rescue of personnel.

[0005] This utility model provides a modular medical rescue cabin system, including a decontamination cabin, a dose detection cabin, and an emergency cabin. The decontamination cabin includes a changing room for initial inspection, a decontamination room, a drying room, and a re-inspection room connected in sequence. The decontamination room is equipped with a first decontamination device. The dose detection cabin includes a detection room, which is equipped with internal and external irradiation dose detection devices. The emergency cabin includes an emergency room, which is equipped with a decontamination treatment bed and a second decontamination device.

[0006] Beneficial effects: The modular medical rescue cabin system consists of three cabins. Personnel contaminated with radioactivity are first categorized. Those with severe conditions who cannot decontaminate themselves are transported to the emergency cabin by medical personnel, where they undergo surface decontamination and first aid using a decontamination treatment bed and a second decontamination device. Others who can decontaminate themselves enter the decontamination cabin for surface decontamination using the first decontamination device, and then proceed to the dose detection cabin to assess their radiation dose, allowing for appropriate subsequent treatment based on the exposure level. By setting up three modular cabins with different functions, personnel can be rationally and specifically categorized and treated according to their radioactivity levels, facilitating targeted rescue efforts.

[0007] In one optional embodiment, the first decontamination device includes a full-body spray head and a local spray head, wherein the rated water pressure of the local spray head is lower than the rated water pressure of the full-body spray head.

[0008] Beneficial effects: Full-body shower heads are suitable for rinsing the entire body of a person, while local shower heads are suitable for rinsing local areas such as the mouth, eyes, and wounds that are difficult to be effectively covered by full-body showers. Setting up local shower heads helps to improve the disinfection effect of personnel. Local shower heads use a lower rated water pressure to avoid damaging sensitive areas such as the conjunctiva and mucous membranes of personnel.

[0009] In one alternative embodiment, the second decontamination device includes a decontamination tank, and the decontamination treatment bed includes a drain hole.

[0010] Beneficial effects: Individuals unable to disinfect themselves are placed on the disinfection treatment bed, and medical staff draw water from the disinfection pool to disinfect the person's body surface and wounds. Wastewater generated during disinfection can be drained away through the drain hole. Using a disinfection treatment bed with a drain hole makes it easier to perform disinfection operations for people with limited mobility.

[0011] In one alternative implementation, a connecting channel is also included, which sealably connects the outlet of the decontamination chamber and the inlet of the dosing detection chamber.

[0012] Beneficial effects: Personnel who have completed decontamination in the decontamination chamber can enter the dose detection chamber through the connecting passage for subsequent dose detection. The connecting passage can prevent external air containing radioactive substances from re-contaminating the personnel after decontamination.

[0013] In one optional embodiment, the decontamination chamber is equipped with a first fresh air device, and the dosage detection chamber is equipped with a second fresh air device. The first fresh air device is used to create a positive pressure environment in the decontamination chamber, and the second fresh air device is used to create a positive pressure environment in the dosage detection chamber.

[0014] Beneficial effects: The first fresh air unit supplies filtered clean fresh air to the decontamination chamber, and the second fresh air unit supplies filtered clean fresh air to the dosimetry chamber, thereby creating a positive pressure environment in the decontamination chamber and the dosimetry chamber, preventing external air containing radioactive substances from polluting the internal environment.

[0015] In one alternative embodiment, the first fresh air device includes a first fresh air fan for supplying fresh air to the re-inspection room. The decontamination chamber is also equipped with a first exhaust valve, which connects the initial inspection room and the external environment and can be opened in response to the pressure in the initial inspection room being greater than a first positive pressure.

[0016] Beneficial effects: Fresh air enters the decontamination chamber from the re-inspection room, passes through the drying room, decontamination room, and initial inspection room in sequence, and is finally discharged from the first exhaust valve in the changing room and initial inspection room. This creates an airflow in the decontamination chamber that is opposite to the movement route of personnel, preventing air containing radioactive materials from entering the drying room from the changing room and initial inspection room as personnel move, thus maintaining the cleanliness of the drying room and preventing personnel from being recontaminated after decontamination.

[0017] In one optional embodiment, the second fresh air device includes a second fresh air fan for supplying fresh air to the testing chamber. The dose detection cabin is also provided with a third exhaust valve, which connects the testing chamber to the external environment and can be opened in response to the pressure in the testing chamber being greater than a third positive pressure, wherein the third positive pressure is greater than the first positive pressure.

[0018] Beneficial effect: The third exhaust valve maintains the rated pressure of the dosage detection chamber at the third positive pressure. Since the third positive pressure is greater than the first positive pressure, when personnel enter the dosage detection chamber from the decontamination chamber, the gas flows from the detection chamber to the connecting channel along the pressure gradient, forming an airflow opposite to the personnel's movement route, thereby maintaining the cleanliness of the detection chamber.

[0019] In one optional embodiment, the emergency medical unit is equipped with a third fresh air system and a third exhaust air system, which are used to create a positive pressure environment within the emergency medical unit.

[0020] Beneficial effects: The third fresh air unit introduces filtered clean fresh air into the emergency medical cabin, thereby creating a positive pressure environment inside the cabin and preventing external air containing radioactive substances from polluting the internal environment. The third exhaust air unit efficiently exhausts the air from the emergency medical cabin, thus helping the air cleanliness inside the cabin to quickly reach the level required for surgery, facilitating rapid emergency medical treatment.

[0021] In one optional embodiment, the emergency medical unit is further provided with an air curtain device, which is used to generate an air curtain covering the entrance and exit of the emergency medical unit.

[0022] Beneficial effects: When personnel enter and exit, the air curtain formed by the air curtain device can prevent pollutants in the outside air from entering the emergency room, thereby reducing the pollutants brought into the emergency room by personnel, reducing the workload of the third fresh air unit, and helping the air cleanliness in the emergency room to reach the target level more quickly, so as to carry out the first aid of the injured as soon as possible.

[0023] In one alternative embodiment, the emergency medical unit further includes an air filter disposed within the emergency medical unit, the air filter being used to purify the air in the emergency medical unit. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. 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.

[0034] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a," "an," and "comprising" as used herein may also mean including the plural forms. The terms "comprising," "including," and "having" are inclusive and therefore indicate the presence of the stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0035] Although terms such as "first," "second," etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Furthermore, in the description of this application, unless otherwise expressly specified and limited, the terms "set up" and "connected" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a direct connection or an indirect connection via an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "end," "length," "inner," "outer," etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation, in addition to those depicted in the figure. For example, if the mechanism in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0037] In responding to a sudden nuclear accident, the relevant technology typically involves deploying a decontamination unit (VMU) on-site to perform emergency decontamination on personnel before transferring them to medical facilities for further treatment. However, the situation on-site is complex, and a single decontamination unit (VMU) cannot meet the rescue needs of different personnel. Furthermore, decontamination can only remove radioactive material from the surface of the personnel's bodies, but cannot assess their exposure or the level of radioactive material in their bodies, which is not conducive to providing targeted medical treatment afterward.

[0038] The following is combined with Figures 1 to 6 The following describes embodiments of the present invention.

[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5According to an embodiment of the present invention, a modular medical rescue cabin system is provided, including a decontamination cabin 1, a dose detection cabin 2, and an emergency cabin 3. The decontamination cabin 1 includes a changing room 101, a decontamination room 102, a skin drying room 103, and a re-examination room 104 connected in sequence. The decontamination room 102 is equipped with a first decontamination device. The dose detection cabin 2 includes a detection room 201, which is equipped with an internal and external irradiation dose detection device 203. The emergency cabin 3 includes an emergency room, which is equipped with a decontamination treatment bed 301 and a second decontamination device 303.

[0040] In response to a sudden nuclear accident, medical personnel categorize those contaminated with radioactive material at the scene. Those in serious condition who cannot decontaminate themselves (e.g., seriously injured individuals) are transported to the emergency shelter 3 and placed on decontamination beds 301. Medical personnel then use a second decontamination device 303 to perform surface decontamination and provide first aid. Other personnel capable of self-decontamination first enter the decontamination shelter 1. In the initial changing and inspection room 101, they remove clothing contaminated with radioactive material and conduct a preliminary visual inspection of their body. In the decontamination room 102, they decontaminate themselves using the first decontamination device. After drying in the drying room 103, they enter the re-examination room 104 to assess the effectiveness of the decontamination. If the decontamination is successful, the personnel enter the dose detection shelter 2, where the internal and external radiation dose detection devices 203 assess the radiation dose received, allowing for appropriate subsequent treatment. If the decontamination is unsuccessful, the personnel return to the decontamination room 102 for further decontamination.

[0041] By setting up three modular cabins with different functions, the decontamination cabin 1 and the dose detection cabin 2 serve personnel with independent decontamination capabilities who require subsequent classification and treatment, while the emergency cabin 3 serves personnel without independent decontamination capabilities who require on-site emergency treatment. This allows for reasonable and targeted classification and treatment of personnel based on their different levels of radioactive contamination, which is helpful for targeted rescue.

[0042] Optionally, to ensure one-way movement of personnel and prevent unqualified personnel from moving in the opposite direction, the initial inspection room 101 is also directly connected to the re-inspection room 104. In this way, personnel whose disinfection effect is not qualified in the re-inspection room 104 can directly enter the initial inspection room 101 and then go to the disinfection room 102 again according to the personnel's direction, thus ensuring the order of personnel movement.

[0043] Understandably, in order to provide different functions and meet the treatment needs of different types of people, the decontamination cabin 1, dosage detection cabin 2, and emergency cabin 3 are adaptively equipped with different facilities and equipment.

[0044] Optionally, refer to Figure 4In some embodiments, the first decontamination device includes a full-body shower head 1061 and a localized shower head 1062. The full-body shower head 1061 is suitable for rinsing the entire body of a person, while the localized shower head 1062 is suitable for rinsing localized areas such as the mouth, eyes, and wounds that are difficult to effectively cover with the full-body shower. The localized shower head 1062 helps improve the decontamination effect. Exemplarily, the full-body shower head 1061 can be a conventional shower head, while the localized shower head 1062 can be a relatively small nozzle.

[0045] Furthermore, in some embodiments, the rated water pressure of the local spray head 1062 is lower than the rated water pressure of the whole body spray head 1061. The use of a smaller rated water pressure in the local spray head 1062 helps to avoid damage to sensitive areas of the personnel, such as the conjunctiva and mucous membranes, during decontamination.

[0046] In some embodiments, the decontamination cabin 1 further includes a first waste cabinet 109, which is located inside the changing and initial inspection room 101. Clothing contaminated with radioactive materials removed by personnel can be stored uniformly in the first waste cabinet 109 for centralized collection and disposal.

[0047] Optionally, in some embodiments, the first waste cabinet 109 abuts against the wall of the decontamination chamber 1, and the wall is provided with a first retrieval door corresponding to the first waste cabinet 109. Staff can directly retrieve clothing from the first waste cabinet 109 through the first retrieval door from the outside without entering the decontamination chamber 1, thus improving the ease of use of the decontamination chamber 1.

[0048] In some embodiments, the re-examination chamber 104 includes a whole-body contamination detector that uses plastic scintillation detection technology to detect contaminants carried by personnel. The skin-drying chamber 103 is equipped with a dryer that provides hot air to remove liquid water from the skin, preventing the injured person from catching a cold, while also ensuring the normal operation of the whole-body contamination detector used for re-examination.

[0049] In addition, the decontamination cabin 1 also includes a first door 108, which is used to separate the various compartments of the decontamination cabin 1 (i.e., the changing room 101, the decontamination room 102, the drying room 103 and the re-inspection room 104) and the compartments from the external environment. The first door 108 is closed when no personnel pass through, so as to reduce the gas exchange between the compartments and the gas exchange between the compartments and the external environment.

[0050] Optionally, in some embodiments, in addition to internal and external irradiation dose detection, the dose detection cabin 2 can also be equipped with detection functions such as neutron dose detection and personal gamma dose detection. For example, personal gamma dose detection can be performed using a thermoluminescent dosimeter, by sending the thermoluminescent dosimeter worn by the person into the thermoluminescent dosimeter for personal gamma dose detection.

[0051] It is understandable that the internal and external radiation dose detection device 203 used in the dose detection cabin 2 can choose existing mature detection products and methods, such as using a whole-body counter or a local counter to measure the liveness of personnel, which will not be elaborated here.

[0052] In some embodiments, the testing room 201 is also equipped with a clean cabinet containing disposable full-body contamination protective suits. Personnel wear full-body contamination protective suits and protective masks to conduct radiation dose testing and exit the room after completing the testing.

[0053] In addition, the dose detection cabin 2 also includes a second door 205, which is used to separate the various compartments of the decontamination cabin 1 (e.g., the detection room 201) and the compartments from the external environment. The second door 205 is closed when no personnel pass through, so as to reduce gas exchange between the compartments and between the compartments and the external environment.

[0054] Optionally, refer to Figure 5 In some embodiments, the second decontamination device 303 includes a decontamination tank, and the decontamination treatment bed 301 includes a drain hole.

[0055] Personnel who are unable to disinfect themselves are placed on the disinfection treatment bed 301. Medical staff take water from the disinfection pool to disinfect the personnel's body surface and wounds. The wastewater generated during disinfection can be discharged through the drain hole. The use of the disinfection treatment bed 301 with a drain hole makes it easier to perform disinfection operations for personnel with limited mobility.

[0056] Furthermore, referring to Figure 6 The decontamination and treatment bed 301 may include a fastening structure for locking the stretcher 302 used to transport the injured. By providing the fastening structure, the stretcher 302 can be stably placed on the decontamination and treatment bed 301. Exemplarily, the fastening structure includes clamps located at the four corners of the decontamination and treatment bed 301, which are used to fasten with the handles of the stretcher 302, thereby achieving quick locking. In addition, the fastening structure may employ other fastening forms found in related technologies, which will not be elaborated upon here.

[0057] In some embodiments, the emergency medical shelter 3 also includes a second waste container 3071, which is located inside the emergency room. The second waste container 3071 collects waste generated during the emergency response for subsequent centralized processing.

[0058] Optionally, refer to Figure 5In some embodiments, the second waste cabinet 3071 abuts against the wall of the emergency shelter 3, with the side of the second waste cabinet 3071 open towards the wall. The wall is provided with a second retrieval door corresponding to the second waste cabinet 3071. Staff can directly retrieve clothing from the second waste cabinet 3071 through the second retrieval door from the outside without entering the emergency shelter 3, thus improving the ease of use of the emergency shelter 3.

[0059] In some embodiments, the emergency room is also equipped with an instrument table 3072 and an ultraviolet lamp for placing emergency-related medications (such as anti-radiation drugs and ovulation-inducing drugs), instruments, and for disinfecting the instruments and the environment. In some embodiments, the emergency room is also equipped with emergency equipment such as a portable emergency ventilator, a defibrillator monitor, an electric suction device, an oxygen cylinder 3073, an infusion hook, and an infusion pump.

[0060] In some embodiments, the emergency room is also equipped with a commode 3074 and a seat 3075. During breaks in surgery, medical staff can rest on the seat 3075 and use the commode 3074 to address urgent physiological needs, reducing the frequency of entry and exit from the emergency room and preventing the introduction of contaminants due to personnel entering and exiting. Optionally, the commode 3074 can be a portable commode 3074 that is not connected to the external environment, and excrement is collected in the commode 3074 for subsequent processing.

[0061] In addition, the emergency medical unit 3 also includes a third door 304, which is used to separate the various compartments of the emergency medical unit 3 (such as the emergency room) and the compartments from the external environment. The third door 304 is closed when no personnel pass through, so as to reduce the gas exchange between the compartments and between the compartments and the external environment.

[0062] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the modular medical rescue cabin system also includes a connecting channel 4, which seals the exit of the decontamination cabin 1 and the entrance of the dose detection cabin 2. Personnel who have completed decontamination in the decontamination cabin 1 enter the dose detection cabin 2 through the connecting channel 4 for subsequent dose detection. The connecting channel 4 prevents external air containing radioactive materials from re-contaminating the personnel after decontamination.

[0063] In some embodiments, the decontamination chamber 1 is equipped with a first fresh air device, and the dosage detection chamber 2 is equipped with a second fresh air device. The first fresh air device is used to create a positive pressure environment within the decontamination chamber 1, and the second fresh air device is used to create a positive pressure environment within the dosage detection chamber 2. The first fresh air device supplies filtered clean fresh air to the decontamination chamber 1, and the second fresh air device supplies filtered clean fresh air to the dosage detection chamber 2, thereby creating a positive pressure environment within both the decontamination chamber 1 and the dosage detection chamber 2, preventing external air containing radioactive materials from polluting the internal environment.

[0064] Furthermore, in some embodiments, the first fresh air device includes a first fresh air unit 1071, which is used to supply fresh air to the re-inspection room 104. The decontamination cabin 1 is also provided with a first exhaust valve 1072, which connects the changing room 101 and the external environment and can be opened in response to the pressure of the changing room 101 being greater than a first positive pressure.

[0065] On the one hand, compared to the uncontrolled leakage of fresh air from the gaps in the decontamination chamber 1, by setting the first exhaust valve 1072, the air is discharged at a fixed point after the pressure exceeds the first positive pressure, which can more reliably control the positive pressure level inside the decontamination chamber 1. On the other hand, fresh air enters the decontamination chamber 1 from the re-inspection room 104, passes through the dry room 103 and the decontamination room 102, and is finally discharged from the first exhaust valve 1072 of the changing room 101. This creates an airflow inside the decontamination chamber 1 that is opposite to the movement route of the personnel, preventing air containing radioactive materials from entering the dry room 103 from the changing room 101 as the personnel move, thereby maintaining the cleanliness of the dry room 103 and preventing the personnel from being recontaminated after decontamination.

[0066] In some embodiments, the second fresh air device includes a second fresh air fan 2041, which is used to supply fresh air to the detection chamber 201. The dose detection cabin 2 is also provided with a third exhaust valve 2042, which connects the detection chamber 201 and the external environment and can be opened in response to the pressure of the detection chamber 201 being greater than a third positive pressure, where the third positive pressure is greater than the first positive pressure.

[0067] The third exhaust valve 2042 maintains the rated pressure of the dose detection chamber 2 at the third positive pressure. Since the third positive pressure is greater than the first positive pressure, when personnel enter the dose detection chamber 2 from the decontamination chamber 1, the gas flows from the detection chamber 201 to the connecting channel 4 along the pressure gradient, forming an airflow opposite to the personnel's movement route, thereby maintaining the cleanliness of the detection chamber 201.

[0068] Using an independent second fresh air unit 2041 and a third exhaust valve 2042 to control the pressure in the testing chamber 201 separately can reduce the load on the first fresh air unit 1071 and ensure stable pressure control. In addition, after the test is completed, when personnel leave the dosing test chamber 2, unfiltered outside air may enter the testing chamber 201. By setting up a third exhaust valve 2042 that connects to the outside, the contamination in the testing chamber 201 can be prevented from spreading to the decontamination chamber 1.

[0069] It should be noted that, due to the long gas flow path, a single first exhaust valve 1072 cannot guarantee that the gas will not flow backward in the decontamination chamber 1. Therefore, in related technologies, exhaust valves are generally configured in each compartment, with different opening pressures set for each exhaust valve, and the opening degree of each exhaust valve is independently controlled to form a pressure gradient that decreases from large to small.

[0070] However, in scenarios such as maritime rescue, the ambient air pressure around the shelter fluctuates due to external wind disturbances. This causes changes in the air supply of the fresh air unit and the exhaust volume of the exhaust valve, which may still lead to external gas entering the cabin through the exhaust valve. In some cases, the pressure gradient may be disrupted, causing gas to flow backward between the cabins, resulting in contamination of the cabin.

[0071] Increasing the rated positive pressure of the chamber with the lowest pressure (which is also known as increasing the first positive pressure in this invention) and the rated pressure difference between adjacent chambers can improve the flow field's resistance to disturbances, but it will also raise the overall pressure level of the chambers, placing excessive demands on the air volume of the fresh air unit and increasing the cost of the container.

[0072] Therefore, in some embodiments, the decontamination chamber 1 is also equipped with a second exhaust valve 1073 and a first electric lock. The second exhaust valve 1073 is connected to the re-inspection chamber 104 and the dry skin chamber 103, and can be opened in response to the pressure of the re-inspection chamber 104 being greater than the second positive pressure. The second positive pressure is greater than the first positive pressure. The first door 108 between the decontamination chamber 102 and the changing room 101 and the first door 108 between the decontamination chamber 102 and the dry skin chamber 103 are equipped with first electric locks. When any one of the first electric locks is in the unlocked state, the other first electric locks are in the locked state.

[0073] On the one hand, the present invention utilizes the first electronic lock to make the decontamination chamber 102 act as a buffer, avoiding the direct connection between the changing room 101 and the drying room 103, and further ensuring the unidirectional flow of air between the changing room 101, the decontamination chamber 102 and the drying room 103, thus preventing other compartments outside the changing room 101 from being contaminated.

[0074] On the other hand, the buffering effect of the decontamination chamber 102 means that the exhaust module does not need to actively control the pressure of the decontamination chamber 102 and the drying chamber 103, reducing the number of pressure gradient stages, which helps to adopt a higher first positive pressure and pressure difference, and reduces the risk of external air pollution in the changing room 101.

[0075] Specifically, if the pressure of the initial inspection room 101, the decontamination room 102, the drying room 103, and the re-inspection room 104 is actively controlled by their respective exhaust valves to form a four-level pressure gradient, given the limited maximum pressure that the first fresh air unit 1071 can provide, this design may result in either an excessively low rated positive pressure in the initial inspection room 101, making it difficult to withstand sudden external high pressure, or an excessively small pressure difference between the chambers, which may lead to reverse flow when pressure fluctuates.

[0076] This invention utilizes a decontamination chamber 102 with a buffering function, which enables directional airflow in the four chambers to be guaranteed with only two pressure gradients. This helps to reduce the risk of external air pollution in the changing and initial inspection chamber 101 by using a higher first positive pressure and pressure difference.

[0077] Optionally, in some embodiments, the initial inspection room 101 and the re-inspection room 104 are directly connected, so that people who fail the inspection can return directly from the re-inspection room 104 to the initial inspection room 101, avoiding reverse flow of people.

[0078] Optionally, in some embodiments, multiple decontamination chambers 102 are arranged in parallel. In this case, each decontamination chamber 102 is for single-person use, reducing the interference of the interlocking of the first electronic lock on personnel entry and exit.

[0079] Optionally, in some embodiments, the first positive pressure can be set to not less than 200 Pa, and the pressure difference between the first positive pressure and the second positive pressure can be set to not less than 50 Pa. Using a pressure greater than 200 Pa can reduce the risk of gas entering the changing room 101 from the first exhaust valve 1072 under external wind interference, making the positive pressure airtight system of the medical rescue cabin more suitable for operation in extreme environments such as the sea surface; using a pressure difference greater than 50 Pa can reduce the risk of gas flowing backward between cabins when pressure fluctuates, ultimately making each cabin less susceptible to contamination.

[0080] Taking a first positive pressure of 200 Pa and a pressure difference of 50 Pa as an example, if the pressure gradient design method in the relevant technology is adopted, the pressure of the four chambers will be increased step by step, and the rated positive pressure of the re-inspection chamber 104 should be 350 Pa. However, in this utility model, the re-inspection chamber 104 only needs a positive pressure of 250 Pa, which effectively reduces the implementation cost.

[0081] Correspondingly, when a second exhaust valve 1073 is provided, the third positive pressure should be greater than the second positive pressure, and the pressure difference between the second positive pressure and the third positive pressure can also be set to not less than 50 Pa.

[0082] In some embodiments, the decontamination chamber 1 further includes a first buffer chamber 105, and the dosage detection chamber 2 further includes a second buffer chamber 202. The first buffer chamber 105 is connected to the changing and initial inspection room 101, and a first door 108 is provided between the first buffer chamber 105 and the external environment. Personnel first enter the first buffer chamber 105 from the outside, and then enter the changing and initial inspection room 101. The second buffer chamber 202 is connected to the detection room 201, and a second door 205 is provided between the second buffer chamber 202 and the external environment. Personnel first enter the second buffer chamber 202 from the detection room 201, and then leave the dosage detection chamber 2.

[0083] By setting up a first buffer chamber 105 and a second buffer chamber 202, it is helpful to reduce the amount of contaminants brought into the decontamination chamber 1 and the dosage detection chamber 2 when personnel enter and exit.

[0084] Optionally, in some embodiments, the decontamination chamber 1 further includes multiple second electrically controlled locks, and the dosage detection chamber 2 further includes multiple third electrically controlled locks. Specifically, the first door 108 between the first buffer chamber 105 and the external environment, and the first door 108 between the first buffer chamber 105 and the initial inspection changing room 101, are equipped with second electrically controlled locks. When any one of the second electrically controlled locks is unlocked, the others are locked. The second door 205 between the second buffer chamber 202 and the external environment, and the second door 205 between the second buffer chamber 202 and the detection room 201, are equipped with third electrically controlled locks. When any one of the third electrically controlled locks is unlocked, the others are locked. The use of second and third electrically controlled locks prevents the initial inspection changing room 101 and the detection room 201 from being directly connected to the external environment, thereby further reducing the amount of contaminants brought into the decontamination chamber 1 and the dosage detection chamber 2 by personnel entering and exiting.

[0085] Reference Figure 5 In some embodiments, the emergency medical shelter 3 is equipped with a third fresh air device and a third exhaust air device, which are used to create a positive pressure environment inside the emergency medical shelter 3.

[0086] The third fresh air unit supplies filtered clean fresh air into the emergency medical cabin 3, thereby creating a positive pressure environment inside the cabin and preventing external air containing radioactive substances from polluting the internal environment. The third exhaust air unit efficiently exhausts the air from the emergency medical cabin 3, which helps the air cleanliness inside the cabin 3 to quickly reach the level required for surgery, facilitating rapid emergency medical treatment.

[0087] Optionally, the third fresh air device includes a third fresh air unit 3051, and the third exhaust air device includes a fourth exhaust valve 3052.

[0088] When personnel enter or exit, a brief, localized pressure drop occurs at the entrance / exit, allowing unfiltered outside air to enter the emergency shelter 3 and contaminate the environment inside. Therefore, it is necessary to close the third door 304 and wait for the third fresh air unit to operate for a period of time to ensure that the air cleanliness inside the emergency shelter 3 reaches the target level before surgery can be performed, which is not conducive to the prompt implementation of emergency treatment for the injured.

[0089] Furthermore, in some field environments, due to strong external winds (such as in maritime emergency rescue scenarios), the ventilation efficiency of the third exhaust ventilation device decreases, and pressure loss at the inlet and outlet is more likely to occur, which further prolongs the time required for preoperative fresh air exchange.

[0090] In the decontamination cabin 1 and the dosage detection cabin 2, buffer rooms (such as the first buffer room 105 and the second buffer room 202) can be set up to prevent contaminants from entering the cabin. However, for the emergency cabin 3, the injured often need to be transported by medical staff using stretchers 302 and other tools. Setting up a buffer room requires too much space and will encroach on the space inside the emergency cabin 3, so it is not feasible.

[0091] In some embodiments, the emergency medical shelter 3 is further provided with an air curtain device 306, which is used to generate an air curtain covering the entrance and exit of the emergency medical shelter 3. When personnel enter or exit, the air curtain formed by the air curtain device 306 can prevent pollutants in the outside air from entering the emergency room, thereby reducing the pollutants brought into the emergency room by personnel, reducing the workload of the third fresh air unit, and helping the air cleanliness in the emergency room to reach the target level more quickly, so as to carry out the first aid of the injured as soon as possible.

[0092] In some embodiments, the emergency medical shelter 3 also includes an air filter 308, which is disposed inside the emergency medical shelter and is used to purify the air in the emergency medical shelter.

[0093] Air filter 308 forms an internal circulation loop in the emergency room, thus working with the third fresh air unit to purify the air in the emergency room. This helps the air cleanliness in the emergency room reach the target level more quickly, enabling emergency treatment of the injured to begin as soon as possible. Because air filter 308 is not connected to the external environment, it is not affected by the wind force in the environment, providing a stable air purification effect.

[0094] In some embodiments, the modular cabin (decontamination cabin, dosage detection cabin, emergency cabin) can adopt the structural form of a large panel cabin. In other words, the cabin body is constructed by welding together panels (top plate, bottom plate, front and rear end plates, left and right side plates, internal partitions) and a frame.

[0095] In some embodiments, the panel is a sandwiched insulation panel, specifically including inner and outer skins and an adhesive polyurethane foam board located between the skins, wherein a PVC insulation component is provided between the inner skin and the frame to reduce direct heat conduction between them.

[0096] The inner skin can be made of T1.0 stainless steel plate, the outer skin can be made of T2.0 aluminum plate, and the skeleton can be made of Q235B standard square tubing. The polyurethane foam is made by mixing isocyanate and polyether in a 1:1 ratio and then foaming it. It is formed into polyurethane foam boards of the required size using a high-pressure casting process.

[0097] The panels are connected by welding and corner bracing, meaning the overlaps between the panels are welded to ensure the strength of the cabin. Rigid corner bracing is then added externally to further strengthen the panels. The internal corner bracing uses rounded stainless steel angle steel profiles to ensure easy decontamination within the cabin.

[0098] Secondly, this utility model also provides a rescue method. The rescue method uses the modular medical rescue cabin system provided by this utility model, and the rescue method includes the following steps:

[0099] Triage personnel, classifying them into at least the severely injured, those in a supine position, and others.

[0100] Severely injured and bedridden patients were sent to Emergency Room 3 for decontamination and first aid treatment.

[0101] Other personnel entered the decontamination chamber 1 and the dosage detection chamber 2 in turn to perform decontamination of their bodies and dosage detection on their own.

[0102] Based on the results of the dosage tests, other individuals were categorized to facilitate the arrangement of subsequent medical treatment.

[0103] The rescue method uses the modular medical rescue cabin system provided by this utility model, and therefore has the beneficial effects brought by the modular medical rescue cabin system, which will not be elaborated here.

[0104] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
