Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical equipment, more specifically, the present application relates to a mobile emergency breathing equipment for critical patients. BACKGROUND

[0002] In medical rescue, for the treatment of critical patients, it is necessary to transport and treat the patients in time, therefore, it is necessary to use the emergency bed which can effectively transfer and temporarily rescue the patients, and other emergency equipment is equipped on the emergency bed as much as possible to ensure the safety of the patients.

[0003] Among them, since the emergency bed is not a disposable product, the emergency bed will face different patients, in order to avoid cross infection, it is necessary to lay a disposable bed sheet on the emergency bed when using, for large hospitals, the number of patients needing rescue is large, therefore, a certain number of emergency beds need to be equipped, and when needed, the idle emergency bed is selected for use, in the face of some emergency accidents, there will be relatively more critical patients, which will lead to the phenomenon of shortage of emergency beds, therefore, after the transfer of the previous patient, the emergency bed needs to be put into use again, due to the urgent time, in order to facilitate the rapid replacement of the bed sheet, many emergency beds are equipped with automatic bed sheet replacement and automatic reel system, the equipment is built-in with two reels, one is used for clean bed sheet which is not used, and the other is used for collecting used bed sheet, when the bed sheet needs to be replaced, the system only needs to control the collection reel to wind, so as to wind the used bed sheet and pull the new bed sheet to the examination bed, complete the laying, the whole process is fully automatic, without manual laying or removing the bed sheet, so as to greatly reduce the preparation time and reduce the risk of medical staff contacting contaminated materials.

[0004] However, due to the different actual conditions of critical patients, for example, some patients are injured, blood or body fluid flows out, some patients need to apply disinfectant to the injured part of the body during the transfer process, some patients do not have wounds on the surface of the body, but need to do some detection and apply corresponding coupling agent during the temporary treatment during the transfer process, therefore, some medical waste will be left on the bed sheet during actual use.

[0005] In the actual treatment process, some patients will have syncope, coma and other phenomena, but some critical patients, for example, the injured limbs and the patients with pain, but the patients are relatively conscious, due to unbearable pain, some patients cannot lie down quietly, will struggle relatively, and then cause the bed sheet to wrinkle or disorder, and even break, which cannot fully adhere to the surface of the emergency bed to be completely protected, and then cause some medical waste to flow to the surface of the emergency bed, and then cause pollution, which is not conducive to the reuse of the emergency bed. SUMMARY

[0006] The present invention provides a portable emergency respiratory device for critical care, which aims to solve the problem that some patients struggle, causing the bed sheet to wrinkle or become disheveled, or even tear in severe cases, making it impossible to fully fit the surface of the emergency bed for complete protection. As a result, some medical waste liquid can easily flow onto the surface of the emergency bed, causing pollution and making it difficult to put the emergency bed back into use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a mobile emergency respiratory device for critical care, comprising an emergency bed, a ventilator assembly on the emergency bed, a mattress assembly on the top of the emergency bed, a sheet on top of the mattress assembly, and an unwinding assembly and a rewinding assembly at both ends of the emergency bed, the unwinding assembly being used to install the sheet roll, and the rewinding assembly being used to rewind the sheet.

[0008] The top of the emergency bed is equipped with a blow-in and suction equalization hood, which is set along the length of the emergency bed and embedded in the mattress assembly. The top of the blow-in and suction equalization hood is provided with a long strip opening, and the bottom of the blow-in and suction equalization hood is fixedly installed with a blow-in and suction connecting pipe.

[0009] The emergency bed is equipped with an airflow control component, which includes an inhalation device and an exhalation device. The inhalation and exhalation connection tube is connected to the inhalation device and the exhalation device through a reversing control valve.

[0010] The mattress assembly has resistance-enhancing structures on both sides, with the top surface of the resistance-enhancing structures protruding from the top surface of the mattress assembly.

[0011] In a preferred embodiment, the air blowing and suction equalization hood is located in the middle of the mattress assembly. The air blowing and suction equalization hood is provided with a widening groove. When a negative pressure is formed in the air blowing and suction equalization hood, the bed sheet forms a concave state in the widening groove. Both sides of the top of the widening groove are provided with a soft padding structure.

[0012] In a preferred embodiment, movable side pads are provided on both sides of the mattress assembly, two sets of resistance-increasing structures are respectively provided on the movable side pads, an airbag structure is provided between the movable side pads and the emergency bed, an inflation / deflation connecting pipe is provided at the bottom of the airbag structure, and the airflow control assembly is provided with two sets of suction devices and inflation devices, and the inflation / deflation connecting pipe is connected to another set of suction devices and inflation devices through a reversing valve.

[0013] In a preferred embodiment, the movable side pad is fixedly connected to the emergency bed via a flexible substrate. The movable side pad is fixedly mounted on the flexible substrate. The side of the flexible substrate near the middle of the emergency bed is fixedly connected to the emergency bed. The airbag structure is disposed between the flexible substrate and the emergency bed. The drag-increasing structure is fixedly connected to the flexible substrate.

[0014] In a preferred embodiment, the drag-increasing structure is provided with a piston chamber, in which a piston block is slidably disposed. The top of the drag-increasing structure is provided with an opening corresponding to the piston block. The top of the piston block is provided with a soft barb structure, the length of which is less than the thickness of the bed sheet. The bottom cavity of the piston chamber is connected to the airbag structure through a pipe. A sealing structure is provided between the piston block and the piston chamber.

[0015] In a preferred embodiment, the bed sheet is provided with multiple sets of liquid permeable holes in the area corresponding to the air blowing and suction equalization hood, and the air blowing and suction equalization hood is also provided with a liquid permeable port. The emergency bed is also provided with a through groove structure at the position corresponding to the liquid permeable port, and a liquid collection box is detachably installed at the bottom of the emergency bed at the position corresponding to the liquid permeable port.

[0016] In a preferred embodiment, a pressure roller is rotatably arranged in the widening tank near the liquid inlet, and a roll of adhesive tape is rotatably arranged in the blowing and suction equalization hood. The pressure roller rolls in a rolling engagement with the bottom of the bed sheet, and the adhesive tape of the roll comes into contact with the bed sheet after passing around the pressure roller, with the adhesive surface of the tape in contact with the bed sheet.

[0017] In a preferred embodiment, sliding grooves are provided on both sides of the widening groove, and sliders are rotatably mounted on both ends of the pressing roller. The sliders are slidably mounted in the sliding grooves, and lifting elastic elements corresponding to the sliders are provided in the sliding grooves.

[0018] In a preferred embodiment, both the unwinding assembly and the winding assembly consist of rotating rollers. The rotating rollers of the unwinding assembly are rotatably mounted on the emergency bed, and the rotating rollers of the winding assembly are rotatably mounted on the emergency bed via a drive motor.

[0019] In a preferred embodiment, the emergency bed is provided with a bed frame assembly at the bottom, which consists of a movable base and a lifting adjustment mechanism. The movable base is provided with wheels, and the lifting adjustment mechanism is used to adjust the height of the mattress assembly. An airflow control assembly is installed on the movable base.

[0020] The beneficial effects of this invention are as follows: Before the patient examination, the invention creates negative pressure at the top opening of the air-purifying hood to create negative pressure adsorption on the sheet laid on top of the mattress assembly, thereby strengthening the adhesion of the sheet to the emergency bed. This reduces the probability of the sheet being pulled away, wrinkled, or torn when the patient lies on the emergency bed, ensuring that the sheet can fully cover the emergency bed. This also ensures that medical waste fluid will not enter the surface of the mattress assembly during actual use. After the patient examination, high pressure is created at the opening of the air-purifying hood to form an airflow between the sheet and the mattress assembly, creating an airflow barrier between the sheet and the mattress assembly. This reduces the contact air intensity between the sheet and the mattress assembly. When the roll-up assembly rolls up the sheet, it reduces frictional wear between the sheet and the mattress assembly. At the same time, it also enables quick sheet replacement, allowing the emergency bed to be put back into use in a timely manner and improving rescue efficiency. Attached Figure Description

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Refer to the instruction manual appendix Figures 1 to 9 A portable emergency respiratory device for critically ill patients includes an emergency bed 1, a bed frame assembly 11 at the bottom of the emergency bed 1, a ventilator assembly 13 on the emergency bed 1 for providing respiratory assistance to critically ill patients, a hanging rod assembly 14 on the emergency bed 1 for placing other medical devices or drugs, a mattress assembly 2 on the top of the emergency bed 1, a sheet 3 on top of the mattress assembly 2, and a roll-up assembly 31 and a roll-up assembly 32 at both ends of the emergency bed 1, respectively. The roll-up assembly 31 is used to install the roll of sheet 3, and the roll-up assembly 32 is used to roll up sheet 3. Thus, when it is necessary to change the sheet, the used sheet portion can be pulled away by simply rolling up sheet 32, and the new unused sheet portion can be pulled out and covered on top of sheet 3, forming an automatic sheet changing mechanism.

[0033] Furthermore, the top of the emergency bed 1 is provided with a blow-in and suction equalization hood 4, which is arranged along the length of the emergency bed 1. The blow-in and suction equalization hood 4 is embedded in the mattress assembly 2. The top of the blow-in and suction equalization hood 4 is provided with a long strip opening, and the bottom of the blow-in and suction equalization hood 4 is fixedly installed with a blow-in and suction connecting pipe 41, which extends downward through the emergency bed 1.

[0034] An airflow control assembly 12 is installed at the bottom of the emergency bed 1. The airflow control assembly 12 includes an inhalation device and an inhalation device (e.g., a suction pump and an inflation pump). The inhalation-blowing connection pipe 41 is connected to the inhalation device and the inhalation device through a reversing control valve (e.g., connected to the output ends of the suction pump and the inflation pump respectively through the reversing valve). The inhalation device is used to create a negative pressure at the top opening of the inhalation-blowing equalization hood 4 when the patient needs to lie down on the emergency bed 1, so as to create a negative pressure adsorption on the sheet 3 laid on top of the mattress assembly 2, thereby sucking away the air between the sheet 3 and the mattress assembly 2, thereby strengthening the adhesion of the sheet 3 to the emergency bed 1, so as to reduce the probability of the sheet 3 being pulled away or wrinkled or torn when the patient lies down on the emergency bed 1. This ensures that the sheet 3 fully covers the emergency bed 1, preventing medical waste from entering the surface of the mattress assembly 2 during actual use. The air blowing device is used to create high pressure at the opening of the air blowing and suction hood 4 after the patient gets out of bed, forming an airflow between the sheet 3 and the mattress assembly 2. This creates an airflow barrier between the sheet 3 and the mattress assembly 2, reducing the contact intensity between them. When the roll-up assembly 32 rolls up the sheet 3, it reduces frictional wear on the mattress assembly 2, extending the lifespan of the mattress assembly 2. It also allows for quick replacement of the sheet 3, enabling the emergency bed 1 to be used promptly and improving rescue efficiency.

[0035] It should be noted that in the above embodiments, the main body of the air blowing and suction equalization mask 4 corresponding to the patient's back can be set to be smaller to ensure that the patient's main body is still supported by the mattress assembly 2. In addition, in order to improve the patient's comfort when lying down, the air blowing and suction equalization mask 4 can be made of flexible material, such as rubber, and a structure such as a flexible sponge can also be set between the mattress assembly 2 and the emergency bed 1 to improve comfort.

[0036] Both sides of the mattress assembly 2 are provided with a resistance-enhancing structure 5. The top surface of the resistance-enhancing structure 5 protrudes from the top surface of the mattress assembly 2. The resistance-enhancing structure 5 is used to increase the contact friction with the sheet 3. For example, the resistance-enhancing structure 5 is made of rubber strips. In use, firstly, the resistance-enhancing structure 5 supports the edge of the sheet 3, so that a reserved space is formed between the sheet 3 and the mattress assembly 2 in advance. Then, when the air blowing and suction equalization cover 4 sucks air, it can form a negative pressure over the entire area of ​​the sheet 3, which improves the adsorption effect of the sheet 3. After adsorption, the contact pressure between the sheet 3 and the resistance-enhancing structure 5 also increases, which is also conducive to improving the fixing effect of the edge of the resistance-enhancing structure 5. When blowing air, since there is airflow to blow out from between the sheet 3 and the resistance-enhancing structure 5, the resistance of the resistance-enhancing structure 5 to the sheet 3 can be effectively reduced.

[0037] In the above embodiments, in some usage scenarios, there is a relatively large amount of medical waste liquid. This is not only inconvenient for treating excess medical waste liquid, but also prone to overflow, affecting the rolling and replacement of the sheet 3 and the reuse of the emergency bed 1. Therefore, this embodiment also provides the following technical solutions, specifically referring to the appendix to the instruction manual. Figures 4 to 6 The air blowing and suction equalization hood 4 is located in the middle of the mattress assembly 2. The air blowing and suction equalization hood 4 is provided with a widening groove 42. When a negative pressure is formed in the air blowing and suction equalization hood 4, the sheet 3 forms a concave state in the widening groove 42, which makes the medical waste liquid relatively concentrated and less likely to flow to the edge of the sheet 3, and also makes it easier to clean. Both sides of the top of the widening groove 42 are provided with soft padding structures (such as cloth pads or smooth rubber pads) to support and protect the sheet 3.

[0038] It should be noted that, to ensure comfort, the air-blow equalizing mask 4 can be widened and have an expansion groove 42 only at the position behind the patient's buttocks. The main part of the patient's back can remain unchanged. Based on this design, the air-blow equalizing mask 4 is mainly concentrated in the middle of the sheet 3. Although the sheet 3 will cover the top opening of the air-blow equalizing mask 4 when it forms negative pressure, the sheet 3 is mainly made of non-woven fabric, which has a certain degree of water resistance but also breathability. Therefore, continuous air intake is required in the air-blow equalizing mask 4 to maintain continuous negative pressure, which can also create a certain negative pressure in the area of ​​the sheet 3 outside the air-blow equalizing mask 4.

[0039] Refer to the instruction manual appendix Figure 4 and Figure 5The mattress assembly 2 has movable side pads 21 on both sides, and two sets of resistance-increasing structures 5 are respectively installed on the movable side pads 21. An airbag structure 6 is installed between the movable side pads 21 and the emergency bed 1. An inflation / deflation connecting pipe 61 is installed at the bottom of the airbag structure 6. The airflow control assembly 12 is equipped with two independently controlled inhalation and inflation devices, i.e., two sets of each device. The inhalation / deflation connecting pipe 41 connects to one set of inhalation and inflation devices, and the inflation / deflation connecting pipe 61 connects to the other set via a reversing valve. This allows for the inflation and deflation control of the airbag structure 6 using the inhalation and inflation devices. In use, before the patient lies down on the mattress assembly 2, the side facing away from the emergency bed 1 should be controlled first. The airbag structure 6 expands, causing the movable side pad 21 on that side to bulge upwards, which in turn causes the corresponding side of the sheet 3 to deform upwards as well. This increases the space between the sheet 3 and the mattress assembly 2 in the initial state, improves the uniformity of the suction of the sheet 3 when the air blowing and suction equalization hood 4 inhales, and thus improves the stability of the fit between the sheet 3 and the mattress assembly 2. When the patient lies down on the bed, another set of airbag structures 6 (i.e., the airbag structure 6 near the side of the bed) can be controlled to expand, causing the mattress assembly 2 to be raised on both sides, which restricts the patient and prevents the patient from rolling off the bed. It can also make the sheet 3 form a larger indentation, which improves the effect of excess medical waste fluid flowing and concentrating in the middle of the sheet 3, so that doctors can concentrate on treating excess medical waste fluid or other liquids.

[0040] Furthermore, the movable side pad 21 is fixedly connected to the emergency bed 1 via the flexible base plate 211. The movable side pad 21 is fixedly installed on the flexible base plate 211. The side of the flexible base plate 211 near the center of the emergency bed 1 is fixedly connected to the emergency bed 1. The airbag structure 6 is disposed between the flexible base plate 211 and the emergency bed 1. The flexible base plate 211 can be elastically bent. The drag-increasing structure 5 is fixedly connected to the flexible base plate 211 via a downwardly extending structure. Specifically, when the airbag structure 6 inflates, since the side of the movable side pad 21 near the center of the emergency bed 1 is relatively fixed to the emergency bed 1, the bulging state of the movable side pad 21 tends to flip upwards on the outside, so that the overall shape is smoother and more comfortable.

[0041] Based on the above embodiments, in order to improve the fixing effect of the edge of the sheet 3 when it is adsorbed, this embodiment also provides the following technical solution, for details please refer to the appendix of the instruction manual. Figure 7 The drag-increasing structure 5 is provided with a piston chamber 51, and a piston block 52 is slidably disposed in the piston chamber 51. The top of the drag-increasing structure 5 is provided with an opening corresponding to the piston block 52. The top of the piston block 52 is provided with a soft barb structure, such as a plastic needle structure. The length of the soft barb structure is less than the thickness of the sheet 3. The bottom cavity of the piston chamber 51 is connected to the airbag structure 6 through a pipe. A sealing structure is provided between the piston block 52 and the piston chamber 51.

[0042] Specifically, in actual use, while inflating the airbag structure 6 to control its expansion, the increased air pressure inside the airbag structure 6 causes the piston block 52 to move upwards. This causes the soft barbs at the top of the piston block 52 to contact the bed sheet 3 and embed themselves in the bed sheet 3, enhancing the fixation effect on the bed sheet 3. After use, when the airbag structure 6 is deflated, the piston block 52 falls and detaches from the bed sheet 3. Since the airbag structure 6 facing the patient inflates after the patient gets into bed, the patient should not move at this time. Therefore, the soft barbs at the top of the piston block 52 will not contact the patient. Before the patient gets out of bed, the airbag structure 6 deflates and contracts, causing the piston block 52 to move downwards, further preventing contact with the patient. Moreover, since the length of the soft barbs on the piston block 52 is less than the thickness of the bed sheet 3, they will not penetrate the bed sheet 3. Therefore, even if the patient accidentally touches this area, the soft barbs will not cause harm to the patient.

[0043] Furthermore, for some special patients, the examination time is longer and more medical waste fluid is used. Therefore, more medical waste fluid flows on the sheet 3. Although the above-mentioned arrangement can concentrate the medical waste fluid in the middle of the sheet 3, the cleaning effect of wiping the medical waste fluid alone is poor in actual cleaning. Therefore, this embodiment also provides the following technical solution, which can be found in the appendix of the instruction manual. Figures 8 to 9 The sheet 3 is provided with multiple sets of liquid permeable holes 33 in the area corresponding to the air blowing and suction hood 4. The liquid permeable holes 33 can adopt a microporous structure or a non-woven fabric structure without a membrane. That is, liquid can permeate downwards here. At the same time, even if the winding component 32 is breathable, it can still adsorb the sheet 3 under the strong operation of the suction device.

[0044] In addition, the blowing and suction equalization hood 4 is also equipped with a liquid inlet 421, which extends downwards. A channel structure is also provided on the emergency bed 1 at the position corresponding to the liquid inlet 421. Correspondingly, a collection box 7 is detachably installed at the bottom of the emergency bed 1 at the position corresponding to the liquid inlet 421. The liquid inlet 421 is mainly located in the area corresponding to the patient's waist and groin. The liquid inlet 421 can be set relatively large to accommodate patients of different body shapes, thus allowing the liquid inlet 421 to target the areas where medical waste liquid is mainly applied. In actual use, while excess medical waste liquid is concentrated in the middle of the sheet 3, under the negative pressure inside the blowing and suction equalization hood 4, the medical waste liquid and other liquids on the top of the sheet 3 are sucked downwards, so that the liquid flows through the liquid permeation hole 33 and through the liquid permeation port 421 into the collection box 7 for collection. When treatment is needed, only the collection box 7 needs to be removed for centralized treatment. The medical waste liquid and other liquids remaining on the surface of the sheet 3 are small in amount and can be directly rolled up without further treatment, thereby improving the treatment efficiency of medical waste liquid and other excess liquids.

[0045] Furthermore, since medical waste liquid sometimes contains coupling agents or bodily fluids, which have a certain viscosity, some residue will form at the bottom of the permeation hole 33 when the medical waste liquid flows downward through it. This residual medical waste liquid will inevitably come into contact with the end of the mattress assembly 2 or other structures used to guide the sheet 3 during the subsequent transport process, causing contamination. Therefore, this embodiment also provides the following technical solution, which is detailed in the appendix to the specification. Figure 9 A pressure roller 43 is rotatably installed in the widening groove 42 near the liquid inlet 421. A roll of adhesive tape 8 is rotatably installed in the air blowing and suction hood 4. Since the roll of adhesive tape 8 is relatively large, a corresponding installation structure can be set at the bottom of the emergency bed 1 to ensure that the outside of the roll of adhesive tape 8 is sealed to prevent air leakage and to ensure the sealing of the widening groove 42 in the adsorption state. The pressure roller 43 rolls in cooperation with the bottom of the sheet 3. After the tape of the roll of adhesive tape 8 passes through the pressure roller 43, it contacts the sheet 3, and the adhesive surface of the tape contacts the sheet 3. In actual use, as the winding assembly 32 winds up the sheet 3, the sheet 3 moves backward. At the same time, the tape will continuously stick to the bottom of the sheet 3, sealing the winding assembly 32 and performing hole repair work. This will cover the medical waste liquid remaining at the bottom of the liquid inlet 33 and ensure the cleanliness of the device.

[0046] Furthermore, both sides of the widened groove 42 are provided with sliding grooves, and both ends of the pressing roller 43 are rotatably mounted with sliders. The sliders are slidably mounted in the sliding grooves, and the sliding grooves are provided with corresponding lifting elastic elements 431, such as springs, for the sliders. The lifting elastic elements 431 are used to provide upward elastic force to the pressing roller 43, thereby forming a buffered contact between the sheet 3 and the pressing roller 43.

[0047] It should be noted that both the unwinding assembly 31 and the winding assembly 32 in this embodiment are composed of corresponding rotating rollers. The rotating roller of the unwinding assembly 31 is directly rotatably mounted on the emergency bed 1, while the rotating roller of the winding assembly 32 is rotatably mounted on the emergency bed 1 via a drive motor, thereby enabling the winding assembly 32 to have winding power. At the same time, each rotating roller is also provided with a detachable structure for the corresponding material roll to facilitate the replacement of the bed sheet 3 material roll. The above-mentioned solutions for the unwinding assembly 31 and the winding assembly 32 are common technologies in existing bed sheet replacement solutions, therefore, this embodiment will not elaborate further.

[0048] In addition, the bed frame assembly 11 consists of a movable base 111 and a lifting adjustment mechanism 112. The movable base 111 is equipped with wheels, and the lifting adjustment mechanism 112 is an automated height adjustment structure, such as a combination of hydraulic cylinder and connecting rod. The lifting adjustment mechanism 112 is used to adjust the height of the mattress assembly 2. The above solutions are also the corresponding solutions of multifunctional examination beds and hospital beds in the existing medical field. Therefore, this embodiment will not be explained in detail.

[0049] The mattress assembly 2 is also equipped with a headrest. In the headrest, or in other places in the mattress assembly 2, corresponding pressure sensors or other sensors are installed to sense whether the patient is lying flat on the bed. This allows the control system to control the corresponding functions, realize automated intelligent control and adjustment, and improve the practicality of the equipment.

[0050] In the above embodiment, the ventilator component 13 used in this embodiment is an intelligent ventilator. When necessary, it records the patient's respiratory parameters. In addition, the ventilator component 13 in this embodiment is only one of the rescue equipment equipped on the emergency bed 1. In actual design and use, other rescue and detection equipment, such as electrocardiogram equipment, can be added as needed. At the same time, a data acquisition and processing system can be added to the emergency bed 1. During the actual use of the emergency bed 1, various vital signs parameters of critically ill patients are collected, and the changes of various vital signs parameters during the rescue and transfer process are recorded. At the same time, a biological and medical health big data sharing platform is established. During the use of the emergency bed 1, the detection parameters are uploaded to the above platform to facilitate the rescue of similar critically ill patients and the improvement analysis of rescue plans, thereby optimizing rescue plans and corresponding rescue equipment.

[0051] In addition, for each hospital system, a corresponding information system and control platform can be established for all emergency beds 1. Each emergency bed 1 can be marked and tracked, and its usage information can be obtained in real time. At the same time, prompting devices (such as buzzers and indicator lights) can be set on each emergency bed 1. In actual use, the platform automatically analyzes the available emergency beds 1 and controls the corresponding emergency bed 1 to issue prompt information according to the usage needs, so as to facilitate the quick retrieval of the emergency bed 1.

[0052] Meanwhile, when emergency beds 1 are in short supply, the aforementioned information system and control platform can track the actual location and usage status of each emergency bed 1, and promptly identify emergency beds 1 that have been used up and put them back into use.

[0053] It should be noted that the biological and medical health big data sharing platform, information system and control platform mentioned above are all based on the emergency respiratory equipment provided by this invention. Each system and platform can be connected to existing platforms, or improved based on existing solutions of mature platforms, such as sharing platforms for various shared devices, etc. This embodiment will not be explained in detail.

[0054] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
