[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The mobile critical care unit medical vehicle of the present invention integrates a medical cabin, a preparation room and a negotiation room, and has functions such as surgical rescue, business negotiation, and rescue preparation.

[0022] At the same time, the present invention is provided with a lift at the corresponding position of the medical cabin, which can adapt to a variety of boarding modes, has good flexibility and strong adaptability. For example, when it is necessary to push a stretcher or wheelchair directly onto the lifting platform from the ground, the lifting platform can be driven to extend from the mobile critical care unit medical vehicle by the telescopic driving mechanism, and then the lifting platform is driven to descend to the ground by the lifting driving mechanism, so that the stretcher or wheelchair can be directly pushed onto the lifting platform, and then the lifting platform is driven to the corresponding height of the medical cabin platform under the drive of the lifting driving mechanism and the telescopic driving mechanism, and then the stretcher or wheelchair and the patient can be directly pushed into the vehicle. When a foldable stretcher is used to transport a patient, the telescopic driving mechanism drives the lifting platform to extend out of the mobile critical care unit medical vehicle. Since the initial state of the lifting platform is already at a certain height corresponding to the height of the foldable stretcher, the foldable stretcher can be directly pushed onto the lifting platform. During the pushing process, the supporting legs of the foldable stretcher are folded at the same time, so that the stretcher and the patient can be pushed onto the lifting platform conveniently and quickly. When the lifting platform rises to a height corresponding to the height inside the vehicle, the supporting legs of the foldable stretcher can be unfolded again and pushed into the vehicle. The advantage of this is that when the lifting platform rises, the height of the foldable stretcher is lowered by folding the supporting legs, which is conducive to improving stability and safety.

[0023] In addition, the bed in the medical cabin can adjust the position of the bed frame and the bed surface through the adjustment mechanism, which is highly flexible and can be adjusted according to the use environment in the vehicle. Secondly, because the profile of the bed frame in the lateral direction is a trapezoid that is wide at the top and narrow at the bottom, while maintaining a sufficient usable area of ​​the bed surface, sufficient space is freed up below the bed surface, especially to avoid the legs of medical staff, so as to reduce obstacles to medical staff in the limited space in the vehicle, which is conducive to allowing medical staff to move more freely when close to the bed. In addition, the mobile medical bed of the present invention also provides convenient conditions for the conversion of stretchers and beds in the vehicle, which is convenient for medical staff to transfer patients between stretchers and beds in the vehicle.

[0076] Furthermore, the bed frame 1b includes a base frame 101b and two support frames; the two support frames are respectively arranged at the two longitudinal ends of the base frame 101b; the transverse profile of the base frame 101b is a trapezoidal shape that is wide at the top and narrow at the bottom; one end of the two support frames is connected to the base frame 101b, and the other end extends upward. By setting up such a bed frame 1b structure, the structure is greatly simplified while the support frames at both ends are used to ensure the support force on the bed surface; at the same time, see Figure 14-16 Such a structure can leave a certain space between the base frame 101b and the bed surface, so that the space below the bed surface is more sufficient, further reducing the impact on the movement and operation of medical staff.

[0077] Furthermore, each of the support frames includes two support rods 102b, which are respectively arranged at the corners of the base frame 101b, and the support rods 102b extend outward and upward obliquely. Such a support frame can be conveniently connected to the bed surface to ensure the stability of the bed surface, and can also be combined with the base frame 101b.

[0078] Furthermore, the longitudinal drive mechanism 2b extends in the longitudinal direction of the bed frame 1b and the bed surface (i.e., the length direction of the bed frame 1b and the bed surface in this embodiment); and the width of the longitudinal drive mechanism 2b is narrower than the bed surface. Furthermore, in this embodiment, the width of the longitudinal drive mechanism 2b is close to that of the base frame 101b, so as to avoid the longitudinal drive mechanism 2b being too wide and occupying too much space.

[0079] Furthermore, since the medical cabin is a long and narrow space, preferably, the adjustment mechanism as a whole is also a structure that is larger at the top and smaller at the bottom. The wider transverse drive mechanism 3b is arranged above the longitudinal drive mechanism 2b, and the bottom of the narrower longitudinal drive mechanism 2b is fixed to the floor of the carriage, ensuring that the floor space on both sides of the bed is maximized to further reduce the movement obstacles of medical staff. The bed frame 1b is arranged on the transverse drive mechanism 3b. The transverse drive mechanism 3b is connected to the power output member of the longitudinal drive mechanism 2 through the longitudinal moving frame 4b; the bed frame 1b is connected to the power output member of the transverse drive mechanism 3b through the transverse moving frame 5b.

[0080] Furthermore, the longitudinal drive mechanism 2b includes a base 202b and a longitudinal electric cylinder 4b disposed on the base 202b; the telescopic rod of the longitudinal electric cylinder 4b is connected to the longitudinal movable frame 4b; the longitudinal movable frame 4b is disposed on the base 202b and can be longitudinally moved. A connecting block 205b is provided on the telescopic rod in this embodiment, and the connecting block 205b is connected to the bottom surface of the longitudinal movable frame 4b.

[0081] Furthermore, a longitudinal guide assembly is provided between the longitudinal movable frame 4b and the base 202b; the longitudinal guide assembly includes a longitudinal guide rail 203b and a longitudinal slider 204b, the longitudinal guide rail 203b is fixedly arranged on the base 202b, the longitudinal slider 204b is fixedly arranged on the bottom surface of the longitudinal movable frame 4b, and the longitudinal slider 204b and the longitudinal guide rail 203b are slidably matched with each other.

[0082] Furthermore, two longitudinal guide assemblies are provided in this embodiment, which is conducive to improving the moving stability of the longitudinal moving frame 4b. At the same time, the longitudinal electric cylinder 4b is arranged between the two longitudinal guide assemblies, making the entire structure more compact and reducing space. In addition, the longitudinal electric cylinder 4b in this embodiment can also adopt other driving methods in the prior art, which is conducive to motor and screw transmission, cylinder, motor and belt transmission, etc.

[0083] Furthermore, an installation space is provided between the base frame 101b and the transverse movable frame 5b, and the transverse driving mechanism 3b is located in the installation space; the transverse movable frame 5b can be laterally movably arranged on the longitudinal movable frame 4b. The transverse driving mechanism 3b includes a transverse motor 301b, a transmission assembly and a screw assembly; the transverse motor 301b is fixedly connected to the bottom surface of the base frame 101b, the transmission assembly includes a synchronous belt 308b, a driving wheel 307b and a driven wheel 303b, and the screw assembly includes a screw rod 306b and a nut block 305b; the nut block 305b is fixedly connected to the longitudinal moving frame 4b, the screw rod 306b cooperates with the nut block 305b, the driven wheel 303b is connected to the screw rod 306b, and the end of the screw rod 306b is rotatably connected to the transverse moving frame 5b, the driving wheel 307b is connected to the main shaft of the transverse motor 301b, and the synchronous belt 308b is wrapped around the driving wheel 307b and the driven wheel 303b. When the bed is adjusted transversely, the transverse motor 301b is started, and the transmission assembly drives the screw rod 306b to rotate, so that the screw rod 306b and the nut block 305b are laterally displaced, thereby driving the transverse moving frame 5b to move synchronously through the screw rod 306b to achieve transverse position adjustment. In addition, the transmission assembly of this embodiment can also adopt the gear chain mode, and the specific implementation method can refer to the prior art.

[0084] Furthermore, a transverse guide assembly is provided between the transverse moving frame 5b and the longitudinal moving frame 4b; the transverse guide assembly includes a transverse guide rail 304b and a transverse slider 302b, the transverse guide rail 304b is fixedly connected to the bottom surface of the transverse moving frame 5b, the transverse slider 302b is fixedly connected to the top surface of the longitudinal moving frame 4b, and the transverse guide rail 304b and the transverse slider 302b are slidably matched with each other. In this embodiment, two transverse guide assemblies are provided, which are respectively located on both sides of the transverse moving frame 5b, so as to form an installation space in the middle of the transverse moving frame 5b.

[0085] Furthermore, the transverse moving frame 5b of this embodiment is roughly in the shape of a rectangular frame, with a hollow middle portion. A profile 501b is provided at a position corresponding to the transverse guide assembly, a square steel 502b is provided on the profile 501b, and the bottom frame 101b is connected to the square steel 502b. With such a transverse moving frame 5b, the structure is simple and reliable, and it is easy to assemble.

[0086] Furthermore, the driving distance of the longitudinal driving mechanism 2b is longer than the driving distance of the transverse driving mechanism 3b. Figure 13-Figure 16 As shown, the driving distance of the longitudinal drive mechanism 2b of this embodiment is long, so that the hospital bed can have sufficient adjustment space in the longitudinal direction, and the driving distance of the transverse drive mechanism 3b is short, as a small adjustment of a short distance. For example, after such a design, the hospital bed of this embodiment can be set near one of the side walls of the medical cabin in the vehicle. When surgery is not required or only for patients to rest, the bed frame 1b can be adjusted to the side wall of the medical cabin in the vehicle through the transverse drive mechanism 3b, so that the bed is placed close to the vehicle body, thereby saving space in the vehicle; and at this time, the longitudinal position can be flexibly adjusted according to the situation, and the adjustment distance of the longitudinal position is long, with a large adjustment space. When surgery or other medical operations are required, the transverse drive mechanism 3b adjusts the bed frame 1b so that the bed frame 1b leaves the inner wall of the vehicle body and reserves a certain distance. The distance should be mainly for medical staff to pass through, so that medical staff can move around the bed at will, which is particularly convenient for surgical operations.

[0087] See also Figure 18-Figure 19, the mobile critical care unit medical vehicle of this embodiment is also provided with a positive and negative pressure regulating system. The positive and negative pressure regulating system includes a fresh air system 4c, an air supply component, an exhaust component, a pressure measuring component for detecting the pressure inside the vehicle, and a first control module 5c. Among them, the fresh air system 4c referred to in this embodiment is a device with a ventilation function, such as an air conditioning unit, a fresh air unit, etc. in the prior art; and, in order to improve the air supply quality and exhaust air harmlessly, the fresh air system 4c should include a filter module, and the filter module at least includes air pre-filtration, primary filtration, deep filtration, sterilization, dehumidification, humidification and other functions. The first control module 5c of this embodiment can be a processor, a chip, or other components with data processing and control functions, and specific details can be referred to the prior art.

[0088] The air supply assembly includes a plurality of air supply ports 7c for supplying air to the vehicle, the plurality of air supply ports 7c are connected to the air supply end of the fresh air system 4c through a pipe, and the plurality of air supply ports 7c are provided with air supply regulating valves 9c for regulating the air output; the exhaust assembly includes a plurality of exhaust ports 8c for exhausting air from the vehicle, the plurality of exhaust ports 8c are connected to the air exhaust end of the fresh air system 4c through a pipe, and the plurality of exhaust ports 8c are provided with exhaust regulating valves 10c for regulating the air intake. The specific implementation structures of the air supply ports 7c and the exhaust ports 8c of this embodiment can refer to the prior art, for example, a grid structure, a U-shaped structure, etc. can be adopted.

[0089] The first control module 5c receives the pressure data of the pressure measuring component, and regulates the air supply regulating valve 9c and the air exhaust regulating valve 10c according to the pressure data, so as to control the air volume supplied into the vehicle and the air volume discharged outside the vehicle.

[0090] According to the actual rescue needs in the vehicle, this embodiment can use the air supply regulating valve 9c and the exhaust regulating valve 10c to adjust the air volume of the air supply port 7c and the exhaust port 8c, so as to achieve flexible adjustment of the air pressure in the vehicle, and form a pressure difference isolation effect of unidirectional airflow, effectively protect the safety of the vehicle environment and avoid the overflow of pathogens. Specifically, when a positive pressure environment is required in the vehicle, the pressure sensor 6c detects the pressure in the vehicle and feeds back the pressure data to the first control module 5c. The first control module 5c increases the air volume of the air supply port 7c and reduces the air intake of the exhaust port 8c according to the pressure data, so that the vehicle environment gradually reaches the preset pressure value and maintains balance; in this environment, a safe and reliable environment can be formed in the vehicle to prevent the air outside the vehicle from entering the vehicle through the structural gap, which is conducive to improving medical work with high environmental requirements such as rescue or surgery. When a negative pressure environment is required inside the vehicle, the air supply regulating valve 9c and the exhaust regulating valve 10c are controlled to reduce the air volume at the air supply port 7c and increase the air intake at the exhaust port 8c, so that the environment inside the vehicle gradually reaches the preset pressure value and maintains a balance. In this environment, it is helpful to prevent the air inside the vehicle from naturally overflowing outside the vehicle through structural gaps, which is particularly suitable for isolation use and can reduce the risk of germ spillover and the impact on the surrounding environment.

[0091] See also Fig.18 Further, in this embodiment, the consultation room 1, the medical cabin 2 and the preparation room 3 are all provided with air supply components and exhaust components; the pressure measuring component includes a plurality of pressure sensors 6c, and the consultation room 1, the medical cabin 2 and the preparation room 3 are all provided with pressure sensors 6c. Preferably, the medical cabin 2 is larger than the consultation room 1 and the preparation room 2; in the medical cabin 2, there are a plurality of air supply ports 7c and exhaust ports 8c.

[0092] In this embodiment, the medical cabin 2 has a large space. In order to create a more comfortable environment, multiple air supply ports 7c and multiple air exhaust ports 8c are arranged along the length of the vehicle body to make the gas flow more uniform. In addition, the multiple air supply ports 7c and multiple air exhaust ports 8c are staggered to avoid the situation where the gas flows directly in and out in a relative state, so that the new air can be more fully mixed with the original air after entering the medical cabin 2c.

[0093] In order to facilitate the assembly and maintenance of the fresh air system 4c, the present embodiment sets the fresh air system 4c at the rear of the mobile critical care unit medical vehicle. Moreover, the fresh air system 4c will inevitably generate certain noise and vibration during operation, so setting it at the rear of the vehicle can reduce its impact on the medical cabin 2 and the negotiation room 1. When replacing a certain component, such as a filter module, the operation is more convenient.

[0094] The pipes connecting the multiple air supply ports 7c and the multiple air exhaust ports 8c in the medical cabin 2 to the fresh air system 4c include a main pipe 11c and a branch pipe 12c; the main pipe 11c extends along the length of the vehicle body, and a plurality of branch pipes 12c are provided, one end of each branch pipe 12c is connected to the main pipe 11c, and the other end of each branch pipe 12c is connected to the air supply port 7c or the air exhaust port 8c. The air supply regulating valve 9c and the exhaust regulating valve 10c are both arranged in the branch pipe 12c.

[0095] See also Fig.19 , further, each air supply port 7c and each air outlet 8c is provided with a filter 13c. Specifically, the specific implementation of the filter 13c can refer to the prior art, or adopt the filtering structure in the prior art, so that it can be more compatible with the air supply port 7c and the air outlet 8c. The filter 13c can filter the air, including but not limited to particles, bacteria, water vapor, etc. in the air, in order to ensure that clean and sterile fresh air enters the car, ensure a good air environment in the car, and at the same time make the air discharged outside the car sterile to avoid the spread of germs.

[0096] Generally speaking, the pressure environment inside a mobile critical care unit medical vehicle includes a positive pressure environment and a negative pressure environment. In a positive pressure environment, the air supply of the air supply component is greater than the exhaust air volume of the exhaust component, and the pressure inside the vehicle is greater than the pressure outside the vehicle; in a negative pressure environment, the air supply of the air supply component is less than the exhaust air volume of the exhaust component, and the pressure inside the vehicle is less than the pressure outside the vehicle.

[0097] In a positive pressure environment, the pressure of the medical cabin 2 is greater than that of the preparation room 3, and the pressure of the preparation room 3 is greater than that of the negotiation room 1. Specifically, the pressure value of the medical cabin 2 in a positive pressure environment can be adjusted to +10Pa, the pressure value of the negotiation room 1 can be adjusted to +5Pa, and the pressure value of the preparation room 3 can be adjusted to +8Pa; under such pressure values, the pressure of the medical cabin 2 as a medical cabin is ensured to be greater than the pressure of other cabins in the vehicle and the atmospheric pressure outside the vehicle, which can prevent air that has not been filtered and sterilized from entering the medical cabin 2.

[0098] In a negative pressure environment, the pressure in the medical cabin 2 is lower than that in the preparation room 3, and the pressure in the preparation room 3 is lower than that in the negotiation room 1. Specifically, the pressure value of the medical cabin 2 in a negative pressure environment can be adjusted to -15Pa, the pressure value of the negotiation room 1 can be adjusted to -5Pa, and the pressure value of the preparation room 3 can be adjusted to -10Pa. In addition, when an isolated environment with a pressure gradient needs to be formed in the vehicle, the negative pressure values ​​between the negotiation room 1, the medical cabin 2 and the preparation room 3 can be increased in sequence in one direction to form an in-vehicle environment with a reasonable pressure gradient and allowing gas to flow in one direction, for example, the negotiation room 1 is -5Pa, the medical cabin 2 is -10Pa, and the preparation room 3 is -15Pa.

[0099] The mobile critical care unit medical vehicle of this embodiment can adjust the air volume of the air supply port 7c and the exhaust port 8c by using the air supply regulating valve 9c and the exhaust regulating valve 10c according to the actual rescue needs in the vehicle through the setting of the positive and negative pressure regulating system, thereby realizing the flexible adjustment of the air pressure in the vehicle and forming a pressure difference isolation effect of unidirectional air flow, effectively protecting the safety of the vehicle environment and avoiding the overflow of pathogens. Specifically, when a positive pressure environment is required to be formed in the vehicle, the pressure sensor detects the pressure in the vehicle and feeds back the pressure data to the first control module 5c. The first control module 5c increases the air volume of the air supply port 7c and reduces the air intake of the exhaust port 8c according to the pressure data, so that the vehicle environment gradually reaches the preset pressure value and maintains balance; under this environment, a safe and reliable environment can be formed in the vehicle to prevent the air outside the vehicle from entering the vehicle through the structural gap, which is conducive to improving medical work with high environmental requirements such as rescue or surgery. When a negative pressure environment is required in the vehicle, the air supply regulating valve 9c and the exhaust regulating valve 10c are controlled to reduce the air volume of the air supply port 7c and increase the air intake of the exhaust port 8c, so that the vehicle environment gradually reaches the preset pressure value and maintains balance; in this environment, it is helpful to prevent the air in the vehicle from naturally overflowing outside the vehicle through the structural gaps, which is especially suitable for isolation use, and can reduce the risk of germs overflowing and the impact on the surrounding environment. In addition, a reasonable pressure gradient can be formed according to the specific conditions of the cabin in the vehicle, which can effectively prevent cross-infection between different cabins in the vehicle. For example, according to the use of each negotiation room 1, medical cabin 2 and preparation room 3, it can be adjusted to a positive pressure environment or a negative pressure environment with a gradient.

[0103] The oxygen concentrator 1d of this embodiment adopts a dual air intake mode to improve the oxygen production effect and quality, especially by arranging pipes in the vehicle, extending the first air intake 19d to the top of the mobile critical care unit medical vehicle, which provides convenience for the oxygen concentrator 1d to absorb high-quality oxygen, and the dual air intake mode is also conducive to increasing the air intake volume of the oxygen concentrator 1d, providing basic guarantee for oxygen production. Of course, the oxygen concentrator 1d of this embodiment can also adopt a single air intake mode, only using the second air intake 20d in the luggage compartment 18d or the first air intake 19d on the top of the mobile critical care unit medical vehicle to achieve air intake, which can be flexibly set according to actual conditions.

[0104] The electric control operation terminal includes a touch display 9d, which is arranged inside the mobile critical care unit medical vehicle; the touch display 9d can display various parameters of the intelligent oxygen supply system and contains various control buttons, and medical staff can operate the control buttons to switch the oxygen supply mode. The touch display 9d can more intuitively and clearly display various parameters of the intelligent oxygen supply system, such as the opening and closing status of the first solenoid valve 10d and the second solenoid valve 11d, the data of the first pressure sensor 3d, the second pressure sensor 7d and the third pressure sensor 17d, and various data and states intelligently fed back by the second control module. Further, the second control module can display various reminder functions on the touch display 9d according to the pressure data of each pressure sensor and the use of the negative pressure oxygen terminal assembly, and can also monitor the intelligent oxygen supply system of the present invention according to the above data, reminding medical staff whether the intelligent oxygen supply system is operating normally, etc.; an air monitoring device can also be arranged inside the mobile critical care unit medical vehicle to transmit information such as the air quality status and the oxygen content of the air inside the mobile critical care unit medical vehicle to the touch display 9d.

[0105] In addition to the display function, the touch display 9d may also include a voice function, which can remind medical staff of the remaining amount of the oxygen cylinder 5d, the oxygen supply demand, etc. through voice broadcast, thereby providing more intelligent oxygen supply, oxygen management and oxygen monitoring for medical staff in the vehicle.

[0106] In addition, in addition to the touch-screen display 9d, the electric control operation terminal of this embodiment can also adopt a mechanical button terminal, which can also realize the switching of the oxygen supply mode.

[0107] The negative pressure oxygen supply component includes a plurality of oxygen supply branches, and the plurality of oxygen supply branches are all connected to the first pipeline 2d and the second pipeline 6d; and the plurality of oxygen supply branches are all connected to the third pressure sensor 17d.

[0108] The plurality of oxygen branches include a first oxygen branch 12d and a second oxygen branch 13d; the first oxygen branch 12d is connected to a plurality of ventilator connection sockets 16d; the second oxygen branch 13d is provided with a plurality of oxygen inhalation connection sockets 16d, and the second oxygen branch 13d is provided with a third pressure reducing valve 14d. The first oxygen branch 12d and the second oxygen branch 13d of this embodiment are used for connecting the ventilator and oxygen inhalation. For details, multiple quick-plug connection sockets can be set in the prior art to facilitate oxygen inhalation for patients.

[0109] Furthermore, in the present embodiment, multiple oxygen cylinders 5d can be provided, and multiple oxygen cylinders 5d can be connected in parallel, and finally unified and connected to the second pipeline 6d. A third solenoid valve, a second pressure sensor 7d and a second pressure reducing valve 8d can be provided on the parallel connection pipelines of multiple oxygen cylinders 5d; each third solenoid valve and each second pressure sensor 7d are electrically connected to the second control module.

The oxygen supply mode with the oxygen generator 1d as the main and the oxygen cylinder 5d as the auxiliary is beneficial to achieving cost savings while ensuring the oxygen supply, eliminating the need to install an oxygen cylinder in the vehicle, and saving space.

When the door 3e of the mobile critical care unit medical vehicle is closed, the door 3e covers the back of the outer box body 101e. The outer box body 101e is hollowed out and closed; an opening is provided on the top of the outer box body 101e, and a cover 1011e that can be opened and closed is provided at the opening; a connecting rod mechanism is provided between the inner box body 102e and the outer box body 101e, one end of the connecting rod mechanism is rotatably connected to the outer wall of the inner box body 102e, and the other end of the connecting rod mechanism is rotatably connected to the inner wall of the outer box body 101e; under the action of external force, the inner box body 102e can be swung out of the vehicle or retracted into the outer box body 101e through the hollow back side of the outer box body.

[0114] See also Figure 26-Figure 27 The negative pressure treatment mechanism 2e of this embodiment includes a shell 201e and a fan 202e arranged in the shell 201e, the air intake of the fan 202e is connected to the inner cavity of the outer box body 101e, and the air outlet of the fan 202e is connected to the outside of the vehicle.

Due to the negative pressure formed in the outer box 101e, the germs bred by the dirt in the inner box 102e cannot spread outward (i.e., inside the vehicle) at will, effectively blocking the path for the dirt and germs to spread inside the vehicle, ensuring a healthy environment inside the vehicle.

[0117] In addition, the air inlet of the fan 202e in this embodiment is not directly connected to the inner cavity of the outer box 101e, but is connected to the outer box 101e through the air guide plate 2011e and the ventilation plate by utilizing the air suction effect of the fan 202e, so that the airflow during the negative pressure treatment process is more balanced and moderate, avoiding excessive impact on the storage box 1e and the dirt therein or generating large noise.
