Specific embodiments

[0018] 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.

[0019] Embodiment 1: As shown in Figures 1-6 and Figures 7-8 , in order to solve the problem that the existing display screen 6 is easily accidentally collided, the process of protecting the display screen 6 of the ventilator is disclosed, and the effect that the ventilator can protect the display screen 6 is achieved. The specific content is as follows: The body 1 and the handle 2 fixedly installed at the upper end of the body 1; a controller 3 and a control knob 7 are fixedly installed at the front end of the body 1, and a protective cover 5 is rotatably installed at the front end of the body 1. The controller 3 is located above the control knob 7. A display screen 6 is arranged inside the body 1, and a docking pipe 4 is fixedly installed on the outside of the body 1; the limiting structure includes a positioning rod 18 and a traction rope 19. The positioning rod 18 is fixedly installed at the upper end of the output end of the telescopic rod 8, and the traction rope 19 is fixedly installed on the outer side of the upper end of the positioning rod 18. One end of the traction rope 19 away from the positioning rod 18 is fixedly connected to the lower end of the protective cover 5, and the traction rope 19 penetrates through the upper end of the body 1; the limiting structure further includes a rotating shaft 20, and the rotating shaft 20 is rotatably installed inside the body 1. A torsion spring 22 is sleeved on the outer side of the rotating shaft 20. A clamping member 21 is fixedly installed on one side of the rotating shaft 20 close to the middle position of the body 1, and the clamping member 21 is clamped and connected to the lower end of the protective cover 5.

[0020] When using this portable ventilator for the emergency department, it is necessary to open the protective cover 5 and move the display screen 6 out of the inside of the body 1 to facilitate medical staff to observe the data displayed on the display screen 6. During the process of opening the protective cover 5, it is necessary to first push the clamping member 21 to rotate. The rotation of the clamping member 21 will cause the rotating shaft 20 to rotate, and the rotation of the rotating shaft 20 will cause the torsion spring 22 to contract. At this time, the clamping member 21 will be separated from the lower end of the protective cover 5. Then, the protective cover 5 can be pushed to rotate and the protective cover 5 can be in an open state. At the same time, the protective cover 5 is made of transparent material, and the situation inside the body 1 can be directly observed; During the process of opening the protective cover 5, the protective cover 5 will pull the traction rope 19 to move. The movement of the traction rope 19 will pull the connecting rod 10 to move, and the movement of the connecting rod 10 will pull the telescopic rod 8 to move and cause the telescopic rod 8 to expand, so that the display screen 6 is moved out of the inside of the body 1 for easy observation and use of the display screen 6. By covering the display screen 6 with the protective cover 5, the display screen 6 can be prevented from being directly damaged by collision; After the ventilator is used, repeating the above operations in reverse can reset the protective cover 5, and at the same time, the clamping member 21 can be clamped with the protective cover 5 to limit the protective cover 5 to ensure the stability of the use of the protective cover 5.

[0021] Embodiment 2: As shown in this embodiment Figures 1-6 In order to solve the problem that the display screen 6 of the existing ventilator is difficult to adjust the angle, the process of adjusting the angle of the display screen 6 of this ventilator is disclosed, and the effect of adjusting the display screen 6 of this ventilator at any angle is achieved. The specific content is as follows: An adjustment structure for controlling the angle of the display screen 6 is provided inside the body 1; the adjustment structure includes a telescopic rod 8, and the telescopic rod 8 is fixedly installed inside the body 1. One end of the telescopic rod 8 close to the protective cover 5 is fixedly installed with a rotating member 9, and one end of the rotating member 9 away from the telescopic rod 8 is rotatably installed with a connecting rod 10, and the connecting rod 10 is located inside the body 1; the end of the connecting rod 10 away from the telescopic rod 8 is rotatably installed with another set of rotating members 9, and the other set of rotating members 9 is fixedly connected to the display screen 6, and the rotating directions of the two sets of rotating members 9 and the connecting rod 10 are opposite; two sets of limit members 15 are slidably installed inside the connecting rod 10, and one ends of the two sets of limit members 15 close to the middle position of the connecting rod 10 are respectively fixedly installed with a fixed cylinder 11 and an installation cylinder 12, and the fixed cylinder 11 is slidably connected to the installation cylinder 12. At the same time, the installation cylinder 12 is located outside the fixed cylinder 11. A support spring 13 is arranged inside the fixed cylinder 11 and the installation cylinder 12, and both ends of the support spring 13 are in close contact with the inside of the fixed cylinder 11 and the installation cylinder 12; a lifting rod 14 is slidably installed at the upper end of the connecting rod 10, and a weight 17 is fixedly installed at the upper end of the lifting rod 14. A sealing member 16 is fixedly installed at the lower end of the lifting rod 14, and the sealing member 16 is hermetically connected to the upper end of the installation cylinder 12, and the sealing member 16 has an inverted frustum-shaped structure.

[0022] When using this portable ventilator for the emergency department, first place the ventilator at the position where it needs to work, and then the ventilator can be turned on to work. During this process, the protective cover 5 needs to be opened and rotated to the upper end of the body 1. After that, the display screen 6 will be pulled out under the action of the traction rope 19. At this time, medical staff can adjust the angle of the display screen 6. During this process, it is necessary to pull the weight 17 upward. The upward movement of the weight 17 will cause the lifting rod 14 and the seal 16 to move upward synchronously. At this time, the seal 16 will be separated from the mounting cylinder 12, and the angle of the display screen 6 can be rotated. During the vertical rotation of the display screen 6, the rotating member 9 fixedly installed on its outer side will be driven to rotate. The rotation of the rotating member 9 will cause the limiting member 15 engaged with it to move inside the connecting rod 10. And during the horizontal rotation of the display screen 6, the rotating member 9 on the outer side of the telescopic rod 8 will be separated from the limiting member 15, and the limiting member 15 will also move inside the connecting rod 10. Then, the fixed cylinder 11 and the mounting cylinder 12 can be brought closer to each other, and the support spring 13 will contract. At the same time, the air between the fixed cylinder 11 and the mounting cylinder 12 will be discharged through the air holes on the outer side of the mounting cylinder 12 (the air holes are sealed with the seal 16). After the display screen 6 completes the angle adjustment, the contracted support spring 13 will expand and push the two limiting members 15 to engage with the two rotating members 9 again, so as to limit the display screen 6. Then, the weight 17 is released, and the weight 17 will return to its original position and cause the seal 16 to seal the air hole at the upper end of the mounting cylinder 12 through the lifting rod 14, thus completing the limitation of the angle of the display screen 6; And the angle adjustment of the display screen 6 is completed by sealing the air pressure between the fixed cylinder 11 and the mounting cylinder 12. When the display screen 6 is accidentally squeezed by excessive gravity, the fixed cylinder 11 and the mounting cylinder 12 will move closer again and squeeze the gas inside them. At this time, the gas inside the mounting cylinder 12 will be discharged and the mounting cylinder 12 will be separated from the seal 16, so that the display screen 6 can rotate under the action of excessive gravity, avoiding damage caused by the angle locking of the display screen 6 and further protecting the display screen 6.

[0023] Embodiment 3: As in this embodiment Figures 1-3 and Figures 9-10 shown, in order to solve the problem that the existing docking tube 4 is easily contaminated, the process of protecting the docking tube 4 of this ventilator is disclosed, achieving the effect of protecting and disinfecting the docking tube 4 of this ventilator. The specific content is as follows: A disinfection structure for the docking tube 4 is provided on the outer side of the body 1; the disinfection structure includes a rotating member 23, and the rotating member 23 is rotatably installed on the outer side of the body 1, and a rotating plate 24 is rotatably installed on the outer side of the rotating member 23, and a protective cover 25 is fixedly installed at one end of the rotating plate 24 away from the rotating member 23; the protective cover 25 is located on the outer side of the docking tube 4, and an annular sterilization lamp 26 and a cylindrical sterilization lamp 27 are fixedly installed inside the protective cover 25, and the cylindrical sterilization lamp 27 is located inside the docking tube 4, and at the same time the annular sterilization lamp 26 is located on the outer side of the docking tube 4; the disinfection structure further includes a sliding member 28 and a positioning member 29, and the sliding member 28 is slidably installed on the outer side of the body 1, and the sliding member 28 is engaged with the rotating plate 24, and the positioning member 29 is fixedly installed on the outer side of the body 1, and the positioning member 29 is engaged with the protective cover 25.

[0024] During the use of this ventilator, it is necessary to dock the docking tube 4 with the breathing mask used by the patient. During this process, it is necessary to move the sliding member 28 upward and separate it from the rotating plate 24, and then the rotating plate 24 can be rotated to drive the protective cover 25 to move, so that the docking tube 4 is exposed. After that, it is necessary to rotate the rotating member 23 so that the protective cover 25 is engaged with the positioning member 29 and the protective cover 25 is attached to the outer side of the body 1 to prevent contamination inside the protective cover 25. After the use of this ventilator is completed, it is necessary to reinstall the protective cover 25 on the outer side of the docking tube 4. After the protective cover 25 is installed on the outer side of the docking tube 4, the annular sterilization lamp 26 and the cylindrical sterilization lamp 27 can be used to perform light sterilization treatment on the inside of the docking tube 4, so as to ensure the cleanliness inside and outside the docking tube 4, facilitate ensuring the cleanliness inside and outside this ventilator, and prevent the ventilator from being contaminated and causing infection, thereby increasing the overall practicality.

[0025] The content not described in detail in this specification belongs to the prior art well known to those skilled in the art.
