Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to a multifunctional portable ventilator and a method for using the same. Background Art

[0002] In modern clinical medicine, as an effective means to artificially replace the function of autonomous ventilation, ventilators have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgeries, respiratory support treatment, and first aid resuscitation, and occupy a very important position in the field of modern medicine. A ventilator is a crucial medical device that can prevent and treat respiratory failure, reduce complications, and save and extend the lives of patients.

[0003] The following drawbacks still exist in the use of ventilators in the prior art:

[0004] 1. Existing ventilators are generally not convenient to carry and can only be placed in hospitals. When a patient needs first aid outside the hospital, it is very difficult to carry the ventilator to the patient's side in time, thus affecting the best rescue time.

[0005] 2. When the ventilator provides first aid to a patient outside the hospital, in order to ensure that the patient can fully absorb oxygen, medical staff need to hold up and fix the patient's head to ensure the patency of the respiratory tract, which increases the operation burden of medical staff and may affect the treatment efficiency.

[0052] Refer to Figures 4 - 7, the auxiliary structure includes a cushion block 14 fixed to the inner wall of the bottom of the box body 1. Rotating shafts 15 are rotatably connected to both sides of the top of the cushion block 14. Connecting rods 17 are fixedly sleeved on the outer walls of the two rotating shafts 15. Connecting seats are rotatably connected to the ends of the two connecting rods 17 away from the cushion block 14, and both connecting seats are slidably connected to one side of the placing plate 8. The rotation of the connecting rod 17 can drive the placing plate 8 to move. Gear 16 is fixedly sleeved on the outer walls of the two rotating shafts 15 and is located below the connecting rod 17. Two racks 18 are slidably connected to the inner wall of the bottom of the box body 1, and the racks 18 are meshed with the gear 16. When the rack 18 moves, it can drive the gear 16 to rotate. A same moving block 19 is fixed to the ends of the two racks 18 away from the placing plate 8. The movement of the moving block 19 can drive the two racks 18 to move simultaneously, and one end of the moving block 19 slidably penetrates through one side inner wall of the box body 1 and extends to one side of the box body 1. A spring 49 is fixed to the side of the moving block 19 close to the rack 18. The side of the spring 49 close to the placing plate 8 is fixedly connected to the inner wall of the bottom of the box body 1 through a fixing seat. The elastic force of the spring 49 can push the moving block 19 to move away from the placing plate 8. A rectangular groove 20 is provided on the side of the moving block 19 away from the rack 18. Trajectory inclined grooves 23 are provided on the inner walls of the two sides of the rectangular groove 20 away from each other. The trajectory inclined grooves 23 are inclined. A pin 22 is slidably engaged between the two trajectory inclined grooves 23. The pin 22 can slide in the trajectory inclined groove 23, and the pin 22 and the trajectory inclined groove 23 cooperate to drive the moving block 19 to move. A lifting plate 21 is rotatably sleeved on the outer wall of the pin 22. A lifting block 24 is slidably connected to one side of the box body 1. The lifting block 24 is fixedly connected to one end of the lifting plate 21. The movement of the lifting block 24 can drive the lifting plate 21 to lift and lower. The lifting and lowering of the lifting plate 21 can drive the pin 22 to lift and lower. A pull rope 25 is fixed to the top of the lifting block 24. 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 wound up, which can drive the lifting block 24 to rise.

[0053] When the multifunctional portable ventilator of this embodiment needs to be used, first open the box cover 2. The box cover 2 drives the rotating shaft 3 to rotate. The rotating shaft 3 winds up the pulling 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 toward 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 outwards 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 communicated with the outside through a conduit, and the air outlet is communicated with the airbag 10 through a conduit. The small air pump 27 injects gas into the airbag 10, and the airbag 10 expands. Move the expanded airbag 10 to the back of the patient's neck, which can then lift the lower jaw part of the patient's head and keep the patient's respiratory tract unobstructed. After that, cover the breathing mask 7 on the patient's mouth and nose, and start the small ventilator 5. The small ventilator 5 provides oxygen into the breathing mask 7 through the breathing tube 6 to provide the required oxygen for the patient.

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

[0055] Referring to Figure 8 , on the inner wall of the bottom of the arc-shaped 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 two sides of the arc-shaped plate 33 away from each other, we also fixedly embedded two electrode plates 35, and these two electrode plates 35 can be used to detect the patient's heart rate.

[0056] In actual use, the adjusted arc-shaped plate 33 is put on the patient's head, so that the temperature sensor 34 touches the patient's forehead to measure the body temperature, and at the same time, the two electrode pads 35 respectively touch the two temples of the patient to detect the heart rate. These detected 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 for the patient.

[0057] Refer to Figure 5 , next, we fixedly installed a small air pump 27 on the inner wall of the bottom of the box body 1. This air pump can provide the required air for the airbag 10. The air outlet end of the small air pump 27 is fixedly connected to an air outlet pipe 28. One end of this air outlet pipe 28 is fixedly extended into the airbag 10 to inject air into the airbag 10 to make it expand. 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] Refer to 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. This groove 11 is used to accommodate and fix some key components. On the inner wall of the bottom of the groove 11, we rotatably connected a fixed shaft 12 through a base. A baffle 13 is fixedly sleeved on the outer wall of this fixed shaft 12. This baffle 13 can be used to close the outlet 9 to prevent dust or other sundries 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] Refer to Figure 2 、 Figure 3 and Figure 8 , a display screen 4 is fixedly embedded on the inner wall of the top of the box cover 2. This display screen 4 is electrically connected to the small ventilator 5, the small air pump 27, the temperature sensor 34 and the electrode pads 35 by wire or wirelessly. When the small ventilator 5 is running, its working status, parameters and other information can be displayed in real time through 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 pads 35 can also be displayed on the display screen 4, making the operation status of the entire ventilator clear at a glance and facilitating precise control and adjustment.

[0060] Refer to Figures 1 - 4, on the side of the box body 1 away from the rotating shaft 3, a handle 42 is designed to be rotatably connected. This handle 42 can be conveniently rotated to lift the entire box body 1 and the lid 2 when needed, making the carrying and moving of the ventilator more convenient. The design of the handle 42 fully considers ergonomics, making the hand feeling comfortable during lifting and not easy to slip.

[0061] In summary, 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. At the same time, it can detect the body temperature and heart rate of patients during the first aid process, and can support the back neck of patients to keep the respiratory tract unobstructed, improving the first aid effect.

[0062] The ventilator in the utility model with the publication number of CN221692416U of the small ventilator 5 is of the same model.

[0063] Embodiment 2: Refer to Figure 10 and Figure 11 , on the basis of Embodiment 1, an improvement is made: on the inner wall of one side of the lid 2, a trapezoidal block 48 is fixedly installed. At the same time, on the inner wall of the bottom of the box body 1, a plurality of fixed columns 43 are fixed and a plurality of moving columns 44 are slidably connected. These fixed columns 43 and moving columns 44 are arranged alternately and are respectively located on both sides of the breathing tube 6. On the outer walls of each fixed column 43 and moving column 44, a rotating wheel 45 is rotatably sleeved. These rotating wheels 45 can significantly reduce the friction force suffered by the breathing tube 6 during movement or folding, protecting the breathing tube 6 from damage.

[0064] The tops of the plurality of moving columns 44 are commonly fixed with a connecting plate 46, and on one side of the connecting plate 46, a plurality of first tension springs 26 are fixed. One ends of these first tension springs 26 are fixedly connected to the inner wall of one side of the box body 1, and their function is to enable the moving columns 44 and the connecting plate 46 to automatically return to the initial position when there is no external force.

[0065] On the top of the connecting plate 46, a pushing plate 47 is fixed, and this pushing plate 47 cooperates with the trapezoidal block 48. When the lid 2 closes the box body 1, the inclined surface of the trapezoidal block 48 will push the pushing plate 47 and the connecting plate 46 to move inward. Since the connecting plate 46 is fixedly connected to the plurality of moving columns 44, the moving columns 44 will also move accordingly, arranging alternately with the fixed columns 43, thereby automatically folding the breathing tube 6 and completing the storage work of the breathing tube 6.

[0066] Conversely, when the lid 2 is opened, the trapezoidal block 48 no longer exerts pressure on 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 reset to their initial positions, releasing the storage of the breathing tube 6, so that the breathing tube 6 can be freely unfolded, facilitating the later covering of the breathing mask 7 over the patient's mouth and nose. This design not only simplifies the process of storing and unfolding the breathing tube 6, but also improves the portability and practicality of the entire ventilator.

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

[0068] S1. When in use, the box body 1 and the lid 2 can be carried on the back through the two straps 37, which is easy to carry. In addition, by pulling the pin rod 39 upward to release the engagement with the pin slot 41, the sliding plate 38 can move on the lid 2, and the tightness of the strap 37 when carrying the box body 1 and the lid 2 can be controlled. Moreover, by means of the handle 42, the box body 1 and the lid 2 can be lifted, and the small ventilator 5 can be quickly moved to a designated position for first aid to the patient.

[0069] S2. When treating the patient, open the lid 2. The lid 2 drives the rotating shaft 3 to rotate. The rotating shaft 3 winds up the pulling rope 25 and drives the lifting plate 21 and the pin 22 to move upward. The cooperation between the pin 22 and the track inclined groove 23 drives the moving block 19 to push the rack 18 to move inward. The engagement between 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 inward, which can push the placement plate 8 to move outwards through the outlet 9 to the outside. Then, the small air pump 27 injects gas into the airbag 10, and the airbag 10 expands. The expanded airbag 10 can be moved to the back of the patient's neck, which can lift the lower jaw part of the patient's head, making the patient's respiratory tract unobstructed. Then, the breathing mask 7 is covered over the patient's mouth and nose, and the small ventilator 5 provides the required oxygen for the patient.

[0070] S3. When the airbag 10 is pulled out to support the patient's head, the baffle 13 is rotated into the groove 11 to avoid the baffle 13 causing harm to the patient. When performing first aid on the patient, rotate the sleeve 31, and put the arc plate 33 on the patient's head. The cooperation between the connecting rod 32 and the sleeve 31 can control the distance of the arc plate 33. The temperature sensor 34 touches the patient's forehead to measure the patient's body temperature, and the two electrode plates 35 respectively touch the two temples of the patient to detect the patient's heart rate. And the display screen 4 can real-time display the patient's body temperature, heart rate, and the situation of the small ventilator 5 providing oxygen for the patient.

[0071] S4. After use, place the breathing mask 7 in the box body 1, flip the box cover 2 to close the box body 1. The elastic force of the spring 49 drives the moving block 19 and the placement plate 8 to reset. In addition, 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. The multiple moving columns 44 and the multiple fixed columns 43 are staggered, which can automatically fold the breathing tube 6 to complete the storage of the breathing tube 6. On the contrary, when the box cover 2 is opened, the storage of the breathing tube 6 can be released, which is convenient for later covering the breathing mask 7 on the patient's mouth and nose.

[0072] However, as is well known to those skilled in the art, the working principles and wiring methods of the small ventilator 5, the temperature sensor 34, the electrode patch 35, the small air pump 27 and the display screen 4 are common knowledge. They all belong to conventional means or well-known common sense, so they will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0073] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
