A pull rope 25 is fixed to the top of the lifting block 24, and the top end of the pull rope 25 is fixedly wound around the outer wall of the rotating shaft 3. When the box cover 2 is opened, the rotating shaft 3 rotates, and the pull rope 25 is retracted, which can drive the lifting block 24 to rise.

[0053] When the multifunctional portable ventilator of this embodiment is needed, the box cover 2 is first opened, the box cover 2 drives the rotating shaft 3 to rotate, the rotating shaft 3 reels the pull rope 25 and drives the lifting block 24 to rise, the lifting block 24 drives the pin 22 to move upward through the lifting plate 21, the pin 22 slides in the track inclined groove 23 and drives the moving block 19 to move to the side close to the placement plate 8, the moving block 19 pushes the rack 18 to move inward, the meshing of the rack 18 and the gear 16 drives the rotating shaft 15 to rotate, the rotating shaft 15 drives the connecting rod 17 to rotate toward the middle, and can push the placement plate 8 to move out to the outside through the outlet 9, at this time, the spring 49 is in a stretched state. Then start the small air pump 27, the air inlet of the small air pump 27 is connected to the outside through the catheter, and the air outlet is connected to the airbag 10 through the catheter, the small air pump 27 injects gas into the airbag 10, the airbag 10 is expanded, and the expanded airbag 10 is moved to the back of the patient's neck, so that the lower jaw of the patient's head can be lifted, so that the patient's respiratory tract is unobstructed. Then, the breathing mask 7 is covered on the patient's mouth and nose, and the small ventilator 5 is started. The small ventilator 5 provides oxygen to the breathing mask 7 through the breathing tube 6 to provide the patient with the required oxygen.

[0054] Reference Figure 4 and Figure 8 The detection structure of the ventilator is specifically constructed as follows: On the inner wall of the box body 1 on the side away from the moving block 19, we fixedly installed a mounting plate 29, and this mounting plate 29 is designed to be above the airbag 10. At the top of the mounting plate 29, we connected a circular shaft 30 through a base rotation, and the circular shaft 30 can rotate smoothly. On the outer wall of the circular shaft 30, we fixedly sleeved two sleeves 31, and the two sleeves 31 are distributed along the length direction of the circular shaft 30. One end of each sleeve 31 forms a sliding connection with a connecting rod 32, so that when the sleeve 31 rotates on the circular shaft 30, the connecting rod 32 can move along a certain trajectory. The ends of the two connecting rods 32 away from the circular shaft 30 are fixedly connected to an arc plate 33.

[0055] Reference Figure 8 On the bottom inner wall of the curved plate 33, we fixedly embedded a temperature sensor 34, which can accurately measure the patient's body temperature. At the same time, on the inner walls of the curved plate 33 on both sides away from each other, we also fixedly embedded two electrode sheets 35, which can be used to detect the patient's heart rate.

[0056] In actual use, the adjusted arc plate 33 is put on the patient's head, the temperature sensor 34 touches the patient's forehead to measure the body temperature, and the two electrode sheets 35 touch the patient's two temples to detect the heart rate. These detection data will be processed by the internal circuit and processor, and finally displayed in real time on the display screen 4. At the same time, the display screen 4 will also display the situation of the small ventilator 5 providing oxygen to the patient.

[0057] Reference Figure 5 Next, we fixedly installed a small air pump 27 on the bottom inner wall of the box body 1, which can provide the required air for the airbag 10. The outlet end of the small air pump 27 is fixedly connected to an outlet pipe 28, one end of which is fixedly extended to the inside of the airbag 10, so as to inject air into the airbag 10 to make it inflated. In this way, when it is necessary to provide respiratory support for the patient, we only need to start the small air pump 27 to make the airbag 10 work.

[0058] Reference Figure 5 Finally, regarding the closed part of the outlet 9 of the ventilator, we set a groove 11 on the top of the placement plate 8, which is used to accommodate and fix some key components. On the bottom inner wall of the groove 11, we connected a fixed shaft 12 through the base rotation, and a baffle 13 is fixedly sleeved on the outer wall of the fixed shaft 12. This baffle 13 can be used to close the outlet 9 to prevent dust or other debris from entering the inside of the ventilator when not in use. In actual use, we can open or close the outlet 9 by rotating the baffle 13 to meet different usage requirements.

[0059] Reference Figure 2 , Figure 3 and Figure 8 A display screen 4 is fixedly embedded on the top inner wall of the box cover 2. The display screen 4 is electrically connected to the small ventilator 5, the small air pump 27, the temperature sensor 34 and the electrode sheet 35 through wires or wirelessly. When the small ventilator 5 is running, its working status, parameters and other information can be displayed in real time on the display screen 4 for the user to monitor. At the same time, the air supply status of the small air pump 27, the temperature data detected by the temperature sensor 34, and the bioelectric signals collected by the electrode sheet 35 can also be displayed on the display screen 4, so that the operating status of the entire ventilator is clear at a glance, which is convenient for accurate control and adjustment.

[0060] Reference Figure 1-Figure 4A handle 42 is designed to be rotatably connected on the side of the box body 1 away from the rotating shaft 3. The handle 42 can be easily rotated so that the entire box body 1 and the box cover 2 can be lifted when needed, making it easier to carry and move the ventilator. The design of the handle 42 fully considers ergonomics, making it comfortable to hold and not easy to slip.

[0061] To sum up, the multifunctional portable ventilator has the advantages of simple structure, diverse functions, and convenient operation. It is convenient for medical staff to carry and use it. At the same time, it can detect the patient's body temperature and heart rate during first aid, and can support the back of the patient's neck to keep the patient's airway unobstructed, thereby improving the first aid effect.

[0062] Small ventilator 5 is the same model as the ventilator in the utility model with announcement number CN221692416U.

[0063] Example 2: Reference Fig.10 and Fig.11 , based on the improvement of Example 1: a trapezoidal block 48 is fixedly installed on the inner wall of one side of the box cover 2. At the same time, a plurality of fixed columns 43 are fixed on the inner wall of the bottom of the box body 1, and a plurality of movable columns 44 are slidably connected. These fixed columns 43 and movable columns 44 are arranged alternately and are respectively located on both sides of the breathing tube 6. On the outer wall of each fixed column 43 and movable column 44, a rotating wheel 45 is rotatably sleeved, and these rotating wheels 45 can significantly reduce the friction force on the breathing tube 6 when it is moved or folded, and protect the breathing tube 6 from damage.

[0064] A connecting plate 46 is fixed to the tops of the plurality of movable columns 44, and a plurality of first tension springs 26 are fixed to one side of the connecting plate 46. One end of each of the first tension springs 26 is fixedly connected to an inner wall of one side of the box body 1, and their function is to enable the movable columns 44 and the connecting plate 46 to automatically return to their initial positions when no external force is applied.

[0065] A push plate 47 is fixed on the top of the connecting plate 46, and the push plate 47 cooperates with the trapezoidal block 48. When the box cover 2 closes the box body 1, the inclined surface of the trapezoidal block 48 pushes the push plate 47 and the connecting plate 46 to move inward. Since the connecting plate 46 is fixedly connected to the plurality of movable columns 44, the movable columns 44 will also move accordingly and be arranged in an interlaced manner with the fixed columns 43, so that the breathing tube 6 is automatically folded to complete the storage of the breathing tube 6.

[0066] On the contrary, when the box cover 2 is opened, the trapezoidal block 48 no longer applies pressure to the push plate 47. At this time, under the action of the first tension spring 26, the connecting plate 46 and the moving column 44 will return to the initial position, releasing the storage of the breathing tube 6, so that the breathing tube 6 can be freely unfolded, which is convenient for covering the patient's mouth and nose with the breathing mask 7 later. This design not only simplifies the storage and unfolding process of the breathing tube 6, but also improves the portability and practicality of the entire ventilator.

[0067] A method for using a multifunctional portable ventilator comprises the following steps:

[0068] S1. When in use, the box body 1 and the box cover 2 can be carried on the back through the two shoulder straps 37, and can be easily carried. In addition, by pulling the pin rod 39 upwards, the engagement with the pin groove 41 can be released to allow the sliding plate 38 to move on the box cover 2, and the tightness of the shoulder strap 37 when carrying the box body 1 and the box cover 2 can be controlled.
