Description

Technical Field

[0001] The present invention belongs to the technical field of respiratory therapy equipment, and specifically relates to an ambulance-mounted portable heated and humidified respiratory therapy equipment. Background Art

[0002] In the time-critical medical scenario of pre-hospital emergency and transportation, patients often experience dry airways and viscous secretions due to critical conditions and disrupted body functions. The dry airways reduce the motility of mucosal cilia, and the viscous secretions are difficult to be normally discharged, gradually accumulating in the airways and forming airway obstructions. Such obstructions seriously affect the patient's respiratory function, causing dyspnea, hypoxia, and even endangering life. However, traditional respiratory support devices are inadequate in this situation. They are bulky, difficult to install in the narrow space of an ambulance, occupy a large amount of precious space, and affect the placement of other emergency equipment. Moreover, they are complex to operate, and it is difficult for medical staff to quickly and accurately complete the equipment debugging and use in emergency situations. At the same time, the bumpy environment of the ambulance easily causes traditional equipment to malfunction and affects its stability. Therefore, portable heated and humidified respiratory therapy equipment has emerged. It adopts an integrated design, perfectly integrating the functions of gas heating and humidification with the respiratory support module, which can not only effectively improve the problem of insufficient airway humidification, but also provide stable respiratory support, reducing the risk of airway complications and safeguarding the patient's life and health.

[0003] There is currently disclosed a heated and humidified respiratory therapy equipment with the publication number of CN210433824U, which includes a main body of the respiratory therapy equipment. The main body is provided with a gas source device for providing air flow and a humidifying tank for humidifying the air flow; the air outlet of the gas source device is communicated with the humidifying tank so that the air flow passes through the humidifying tank. The humidifying tank is provided with an air flow outlet, and the air flow outlet is communicated with a respiratory tube so that the humidified air flow is provided to the user through the respiratory tube; the respiratory tube is provided with a heating device capable of heating the air flow in the respiratory tube. This respiratory therapy equipment integrates heating and humidification, can humidify and heat the air flow, making the temperature and humidity of the oxygen inhaled by the patient or user appropriate, without causing damage or discomfort to the body, and the settings of each component are ingenious and convenient to use.

[0004] In the special usage environment of an ambulance, to ensure the stability and safety of the ambulance-mounted portable heated and humidified respiratory therapy equipment during driving on complex road conditions, it is usually necessary to place it in a specially designed protective box for storage. When the ambulance is on a mission, the driving road conditions are complex and changeable, often facing situations such as bumps, sudden brakes, and sharp turns. The protective box can effectively reduce the impact of external forces on the equipment through its strong outer shell and internal buffer structure, preventing the internal parts of the equipment from loosening and being damaged due to violent vibrations, and ensuring the basic safety of the equipment in the non-use state.

[0005] However, this protective storage method exposes many problems in first aid scenarios, seriously affecting the first aid efficiency. When the device needs to be used in an emergency, medical staff are often in a highly tense and busy state. At this time, they need to quickly take out the device from the protection box and carry out a series of preparatory work, such as connecting the power supply, debugging parameters, installing accessories, etc. However, due to the usually relatively closed design of the protection box, the placement position of the device in the box may not be intuitive enough, and medical staff need to spend extra time and energy to find and take out the device. Moreover, after taking out the device, a complex assembly and debugging process is required, which undoubtedly increases the preparation time for first aid. Therefore, it needs to be improved and optimized. Summary of the Invention

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 11 shown, the present invention provides an ambulance-mounted portable warming and humidifying respiratory treatment device, including:

[0038] A protection box 1, which is rectangular in design and is provided with shock-absorbing materials on the inner wall. The shock-absorbing materials are made of polyurethane foam;

[0039] A treatment device 6, which is placed inside the protection box 1;

[0040] An installation box 2, which is fixedly installed on the front of the protection box 1, is in a C-shaped design and the opening is fixedly connected to the outer wall of the protection box 1. Control buttons are provided on the front of the installation box 2;

[0041] Inside the installation box 2, a jacking mechanism is provided. The jacking mechanism includes a driving component and a transmission component. The transmission component includes four first limiting slide bars 11 fixedly installed on the inner wall of the bottom of the protection box 1. The four first limiting slide bars 11 are designed to be rectangularly distributed, and a bearing platform 4 is slidably installed on the outer walls of the four first limiting slide bars 11. The bearing platform 4 is rectangular, and racks 41 are fixedly installed at the tops of the four corners respectively. The treatment device 6 is located on the top of the bearing platform 4. Two clamping components are arranged on the outer wall of the jacking mechanism for fixing the treatment device 6. Two second rotating rods 3 are rotatably installed on the inner wall of the protection box 1, and one end of each of the two second rotating rods 3 extends into the installation box 2. Two second gears 31 are fixedly sleeved on the outer walls of the two second rotating rods 3 respectively. The four second gears 31 are respectively engaged with the corresponding racks 41. Circular grooves 42 are respectively formed at the tops of the four racks 41. The four circular grooves 42 respectively penetrate through the corresponding racks 41 and are respectively slidably connected with the corresponding first limiting slide bars 11. Two protective covers 5 are fixedly sleeved on the outer walls of the two second rotating rods 3 respectively. The two protective covers 5 are respectively located in the middle of the corresponding two second gears 31.

[0042] Adopting the above solution: By setting the jacking mechanism, when the treatment device 6 needs to be used, by pressing the control button on the front of the installation box 2, the two protective covers 5 are driven to open, and the bearing platform 4 drives the treatment device 6 to move upward, realizing the automatic taking out and storage of the treatment device 6, greatly improving the work efficiency of medical staff. Especially in emergency situations, it can be quickly put into use; the shock-absorbing material polyurethane foam on the inner wall of the protection box 1 and the setting of the protective cover 5 effectively prevent the treatment device 6 from being collided and damaged during transportation and use, and extend the service life of the device. This design makes full use of the space inside the protection box 1. Through the jacking mechanism, the vertical lifting of the treatment device 6 is realized without occupying additional space, making the inside of the ambulance cleaner and more orderly; the protective cover 5 can completely cover the top of the protection box 1 in the closed state, preventing external factors such as dust and moisture from entering the inside of the protection box 1, ensuring the cleanliness and dryness of the treatment device 6, and improving the safety and reliability of the device. The protection box 1, as the carrier of the whole device, the shock-absorbing material on its inner wall and the top opening design covered by the protective cover 5 provide a good protection and storage environment for the treatment device 6.

[0043] Such as Figures 1 to 8As shown, the driving assembly includes a power group and a driving group. The power group includes hydraulic cylinders 21 fixedly installed on the inner walls of both sides of the installation box 2. Gear blocks 22 are fixedly installed on the output shafts of the two hydraulic cylinders 21. The two gear blocks 22 are respectively located above and below the gear 2 31. The teeth of the two gear blocks 22 are opened in opposite directions. Slide rails 25 are fixedly installed on the top and bottom inner walls of the installation box 2. The two slide rails 25 are respectively meshed with the corresponding gear blocks 22. The cross-sections of the two slide rails 25 are convex. The block 22 is provided with a matching groove on one side in contact with the corresponding slide rail 25. The driving group includes two rotating rods 23 rotatably installed inside the installation box 2. Chains 24 are fixedly sleeved on the outer walls of the two rotating rods 23. Both chains 24 are engaged with the tooth block 22. The two rotating rods 23 are connected to the adjacent rotating rods 23 through the chains 24. Limiting discs are fixedly sleeved on the outer walls of the two rotating rods 23 and the rotating rod 23. Several limiting discs are located on both sides of the corresponding chains 24.

[0044] The above scheme is adopted: when the hydraulic cylinder 21 of the power group is started, its output shaft is extended and retracted to drive the tooth block 22 to slide along the slide rail 25, and the tooth block 22 is engaged with the chain 24, thereby driving the chain 24 to move. The chain 24 drives the rotating rod 1 23 and the rotating rod 2 3 to rotate through the transmission connection. In this process, since the rotating rod 1 23 and the rotating rod 2 3 are fixedly sleeved with a limiting disc, and the limiting disc is located on both sides of the chain 24, the limiting disc will block and guide the chain 24, preventing the chain 24 from deflecting, falling off, etc. during the movement.

[0045] like Figures 9 to 11 As shown, the two groups of clamping components are designed to be symmetrically distributed, including a round rod 7 fixedly installed on the side where the corresponding two racks 41 are close to each other, two moving blocks 71 are slidably installed on the outer wall of the round rod 7, and connecting rods 72 are respectively hingedly installed on the outer wall of the two moving blocks 71 on the side close to the treatment device 6, and the other ends of the two connecting rods 72 are hingedly installed with fixed plates 73, and the two moving blocks 71 are elastically connected to the corresponding racks 41 through springs 74, and the top of the spring 74 is designed in an outward eight shape.

[0046] The above solution is adopted: the two groups of clamping components are symmetrically distributed, and the cooperation between the round rod 7 and the rack 41 makes the clamping force evenly distributed, effectively reducing the risk of deviation caused by uneven force on the equipment.

[0047] The working principle and use process of the present invention:

[0048] The medical staff presses the control button on the outer wall of the installation box 2, and the button activates the two hydraulic cylinders 21;

[0049] By the telescopic movement of the output shaft of the hydraulic cylinder 21, two tooth blocks 22 are respectively driven to slide along the outer wall of the slide rail 25; the tooth blocks 22 are meshed with the corresponding first gears 231, so that the two first gears 231 respectively drive the corresponding first rotating rods 23 to rotate; the two first rotating rods 23 are connected by the transmission of two chains 24 to respectively drive the corresponding second rotating rods 3 to rotate; the rotation of the two second rotating rods 3 drives the second gears 31 and the protective covers 5 to rotate together; the four second gears 31 are meshed with the corresponding racks 41, so that the four racks 41 drive the bearing platform 4 to move vertically along the axis of the limit slide rod 11; the rotation of the second rotating rod 3 causes the two protective covers 5 to open outwards, and the bearing platform 4 moves upwards, driving the treatment device 6 to move out of the protection box 1 together. When the treatment device 6 needs to be repaired or normally inspected, the medical staff can directly pull out the treatment device 6 upwards, so that the spring 74 rebounds, driving the two moving blocks 71 on the outer wall of the round rod 7 to approach each other. The two moving blocks 71 jointly push the fixing plate 73 to move towards the middle through the connecting rod 72. When it needs to be put back, the treatment device 6 is aligned with the middle of the two fixing plates 73 and pressed downwards, so that the tops of the two fixing plates 73 first contact the treatment device 6. Due to the extrusion of the treatment device 6, the fixing plate 73 causes the two moving blocks 71 to move horizontally away from each other along the axis of the round rod 7 through the connecting rod 72. The two moving blocks 71 extrude the corresponding springs 74. After the treatment device 6 is placed in contact with the inner wall of the bottom of the bearing platform 4, due to the rebound of the spring 74, the two fixing plates 73 fix the treatment device 6 in the bearing platform 4.

[0050] After stopping use: Reverse drive the two hydraulic cylinders 21; the bearing platform 4 drives the treatment device 6 back into the protection box 1; the two protective covers 5 are reset to close the top of the protection box 1 to protect the treatment device 6.
