Detailed implementation manners

[0018] The following further describes the present utility model in conjunction with embodiments.

[0019] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the concept of the present utility model belongs to the scope protected by the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a positive pressure ventilation device for treating hypoxic wounds, including a barrel body 1. The barrel body 1 enables the gas to have a storage point, facilitating the extraction of gas from it by an air outlet pipe 2 into a sheet-shaped airbag 3;

[0021] An air outlet pipe 2 is communicated in the barrel body 1. The other end of the air outlet pipe 2 is provided with a sheet-shaped airbag 3. The air outlet of the air outlet pipe 2 is located inside the sheet-shaped airbag 3. A plurality of exhaust holes 4 are opened at the bottom of the sheet-shaped airbag 3. The sheet-shaped airbag 3 can be attached to the skin of the patient's wound, so that a more intensive oxygen supply to the patient's wound can be realized by means of the plurality of exhaust holes 4;

[0022] A guiding mechanism 5 is arranged outside the air outlet pipe 2. The air outlet pipe 2 is communicated inside the guiding mechanism 5, so that when the guiding mechanism 5 operates, the gas in the barrel body 1 can be introduced into the sheet-shaped airbag 3 by means of the air outlet pipe 2;

[0023] An air inlet pipe 22 is fixedly connected to the outside of the barrel body 1. A valve 23 is arranged inside the air inlet pipe 22. The air inlet pipe 22 enables the outside air to flow into the barrel body 1, so that when the gas is stored in the barrel body 1, it is convenient for the air outlet pipe 2 to extract it therefrom;

[0024] A connecting seat 6 is fixedly connected to the outside of the barrel body 1. A connecting plate 7 is fixedly connected to the outside of the connecting seat 6. A through hole 19 is opened inside the connecting plate 7. A rack 15 is located inside the through hole 19. The through hole 19 enables the rack 15 to have a space for movement. Thus, when the rack 15 moves due to the rotation and engagement of a gear 14, it will not be blocked by the connecting plate 7 and cannot move normally;

[0025] A limiting hole 25 is opened inside the connecting plate 7. A limiting rod 24 is located inside the limiting hole 25. The limiting hole 25 enables the limiting rod 24 to have a limiting movement space. Thus, when a threaded sleeve 11 moves inside the limiting hole 25 by means of the limiting rod 24, it has good stability, preventing the threaded sleeve 11 from rotating relative to a threaded rod 10 at the same time;

[0026] One side of the connecting plate 7 is fixedly connected with a fixing plate 8. A bearing 9 is clamped in the connecting seat 6. A threaded rod 10 is rotatably connected in the bearing 9. A threaded sleeve 11 is externally threaded on the threaded rod 10. A limiting rod 24 is fixedly connected to the outside of the threaded sleeve 11. A connecting block 12 is fixedly connected to the outside of the threaded sleeve 11. One side of the connecting block 12 is fixedly connected with a telescopic baffle 13. When the threaded rod 10 rotates, the threaded sleeve 11 in threaded cooperation with it can drive the telescopic baffle 13 to move upward through the connecting block 12, so that when the telescopic baffle 13 moves upward to a suitable position, it can surround the barrel body 1. And when the telescopic baffle 13 surrounds the barrel body 1, the noise generated by the barrel body 1 can be effectively reduced;

[0027] A first opening 20 is formed in the telescopic baffle 13. The air inlet pipe 22 is located in the first opening 20. The first opening 20 enables the telescopic baffle 13 not to be blocked by the air inlet pipe 22 when moving upward, so as to ensure that the telescopic baffle 13 can move smoothly;

[0028] A second opening 21 is formed in the telescopic baffle 13. The air outlet pipe 2 is located in the second opening 21. The second opening 21 enables the telescopic baffle 13 not to be blocked by the air outlet pipe 2 when moving upward, so as to ensure that the telescopic baffle 13 can move smoothly;

[0029] The bottom of the telescopic baffle 13 is fixedly connected to the upper part of the connecting seat 6. The top end of the threaded rod 10 is fixedly connected with a gear 14. A rack 15 is externally meshed with the gear 14. A fixed block 16 is fixedly connected above the rack 15. A cover plate 17 is fixedly connected above the fixed block 16. When the threaded rod 10 drives the gear 14 to rotate synchronously, the rack 15 meshed with the gear 14 can drive the cover plate 17 to move to the right through the fixed block 16, so as to make the cover plate 17 cooperate with the movement of the telescopic baffle 13 to seal the barrel body 1, so as to achieve the purpose of reducing the noise of the barrel body 1 to a certain extent;

[0030] One side of the rack 15 is fixedly connected with a telescopic rod 18. The other end of the telescopic rod 18 is fixedly connected with one side of the fixing plate 8. The telescopic rod 18 enables the rack 15 to have a fixed point, and at the same time, the telescopic characteristic of the telescopic rod 18 enables the rack 15 to move smoothly when being meshed by the gear 14, so as to ensure the stability of the cover plate 17 during movement.

[0031] The working principle and usage process of the present utility model:

[0032] When the barrel body 1 generates noise due to the air guiding of the air outlet pipe 2, first rotate the threaded rod 10. When the threaded rod 10 rotates, the threaded sleeve 11 in threaded cooperation with the threaded rod 10 can drive the connecting block 12 to move upward, so that the connecting block 12 can drive the telescopic baffle 13 to move upward;

[0033] Meanwhile, the threaded rod 10 can drive the gear 14 to rotate synchronously, so that the rack 15 meshing with the gear 14 can drive the fixed block 16 to move to the right. Thus, when the fixed block 16 drives the cover plate 17 to move to the right to a certain position, the telescopic baffle cover 13 can synchronously rise below the cover plate 17 to achieve the purpose of surrounding and noise reduction for the barrel body 1.

[0034] At this time, the guiding mechanism 5 can be started, so that the guiding mechanism 5 can introduce the gas in the barrel body 1 into the sheet airbag 3 through the air outlet pipe 2, and then discharge it through a plurality of exhaust holes 4 to achieve the purpose of supplying oxygen to the wound surface of the patient.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
