[0004] When using a ventilator, due to different usage scenarios, in certain scenarios with too many impurities, there will be a large amount of impurities in the gas drawn by the ventilator. The presence of impurities will reduce the effect of the ventilator. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a miniature emergency ventilator to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a miniature emergency ventilator, comprising a placement chamber, the bottom of the placement chamber is fixedly connected to a base, the top of the placement chamber is rotatably connected to a top cover, the outer wall of the placement chamber is fixedly connected to a connecting pipe, the end of the connecting pipe is fixedly connected to a breathing mask, the inner wall of the top cover is fixedly connected to a breathing mechanism, the top cover is relatively miniature as a whole, the placement chamber can be directly held and moved around, the top cover is opened when it is needed, and then the breathing mask is put on the face of the person to be rescued, and the breathing mask is connected to the compressed air bag through the connecting pipe;

[0007] The breathing mechanism comprises:

[0008] A compressed air bag, wherein the compressed air bag is fixedly connected to the inner bottom of the storage bin;

[0009] The top plate is fixedly connected to the top of the compressed airbag. The descent of the top plate will squeeze the gas in the compressed airbag, and the gas will be blown out from the breathing mask through the connecting pipe. Then, when the first telescopic machine drives the top plate to rise, the external gas will enter the compressed airbag through the air inlet. When the compressed airbag is compressed and expanded, it will simulate the breathing of the human body, thereby resuscitating the normal breathing of the human body, providing mechanical ventilation support for patients with dyspnea or respiratory arrest, and effectively maintaining the oxygen supply of the patient, preventing serious consequences caused by respiratory failure, and buying precious time for subsequent medical treatment;

[0010] The first telescopic machine is fixedly connected to the inner wall of the storage bin. When the first telescopic machine is powered on and started, it drives the top plate to descend. The descent of the top plate will squeeze the gas in the compressed airbag, and the gas will be blown out from the breathing mask through the connecting pipe. Then, when the first telescopic machine drives the top plate to rise, the external gas will enter the compressed airbag through the air inlet. The top of the first telescopic machine is movably connected to the outer wall of the top plate.

[0011] Preferably, an air inlet is provided at the bottom of the storage bin, and a filter block is fixedly connected to the inner wall of the air inlet.

[0012] Preferably, a groove is provided on the outer wall of the air inlet, and a spring is fixedly connected in the groove of the air inlet.

[0013] Preferably, an impact block is fixedly connected to the outer wall of the spring, and a shifting rod is fixedly connected to the outer wall of the impact block.

[0014] Preferably, an auxiliary mechanism is fixedly connected to the bottom of the placement bin, and the auxiliary mechanism includes a first bearing, which is fixedly connected to the bottom of the placement bin. The second telescopic machine is powered on to drive the movable rod to move, and a cleaning brush is provided on the movable rod. When the second telescopic machine pulls the movable rod, it will pull the rotating disk, and the rotating disk will be driven to rotate during the pulling process. The rotation of the rotating disk will change the rotation angle of the movable rod. When the movable rod changes its angle, it passes through the outer wall of the air inlet, thereby scraping off impurities adhered to the filter block, and the cleaning brush will also clean the impurities on the outer wall of the filter block following the movement of the movable rod.

[0015] Preferably, the outer wall of the first bearing is rotatably connected to a second telescopic machine, and the second telescopic machine will pull the rotating disk when pulling the movable rod, and the rotating disk will be driven to rotate during the pulling process. Because the movable rod is arranged on the rotating disk away from the center of the circle through the second bearing, the rotating disk will be driven to rotate during the process of the second telescopic machine pulling and pushing the movable rod. The rotation angle of the movable rod will be changed in combination with the rotation of the rotating disk. When the angle is changed, the movable rod passes through the outer wall of the air inlet, and thus can scrape off impurities adhered to the filter block. The setting of the outer wall of the movable rod can effectively scrape off impurities adhered to the filter block, avoiding the adhesion of impurities and clogging the filter block. In addition, the cleaning brush will also clean the impurities on the outer wall of the filter block following the movement of the movable rod. The removal of impurities ensures that the outside gas can normally enter the compressed air bag, thereby ensuring the normal supply of gas. The outer wall of the second telescopic machine is movably connected to the movable rod.

[0016] Preferably, a cleaning brush is fixedly connected to the outer wall of the movable rod, and the second telescopic machine is connected to the bottom of the storage bin through a first bearing, so when the movable rod changes its angle, the second telescopic machine is tilted following the change in angle, and the outer wall of the movable rod is fixedly connected to the second bearing.

[0017] Preferably, the outer wall of the second bearing is rotatably connected to a rotating disk, and the rotating disk will touch the activated rod during rotation, thereby driving the impact block to move. After the rotating disk passes the impact block, the elasticity of the spring will drive the impact block to reset, and the impact block will hit the filter block when resetting, thereby squeezing the filter block. For impurities stuck in the filter block, the impact block squeezes the impurities on the filter block to make the impurities fall, and the impact block squeezes the filter block so that some of the stuck impurities are squeezed out, and the subsequent rotation of the movable rod is used to clean the stuck impurities, thereby ensuring normal gas supply, providing mechanical ventilation support for patients with dyspnea or respiratory arrest, and effectively maintaining the patient's oxygen supply to prevent serious consequences caused by respiratory failure. The outer wall of the rotating disk is rotatably connected to a third bearing, and the third bearing is fixedly connected to the outer wall of the base.

[0018] The present invention provides a miniature emergency ventilator. It has the following beneficial effects:

[0019] 1. The miniature emergency ventilator will squeeze the gas in the compressed airbag when the top plate descends, and the gas will be blown out from the breathing mask through the connecting pipe. Then, when the first telescopic machine drives the top plate to rise, the external gas will enter the compressed airbag through the air inlet. When the compressed airbag is compressed and expanded, it will simulate the human body's breathing, thereby enabling emergency human body's normal breathing, providing mechanical ventilation support for patients with dyspnea or respiratory arrest, effectively maintaining the patient's oxygen supply, preventing serious consequences caused by respiratory failure, and buying precious time for subsequent medical treatment.

[0020] 2. The mini emergency ventilator will pull the rotating disk when the movable rod is pulled by the second telescopic machine, and the rotating disk will be driven to rotate during the pulling process. Because the movable rod is arranged at a position away from the center of the circle on the rotating disk through the second bearing, the rotating disk will be driven to rotate during the pulling and pushing of the movable rod by the second telescopic machine. The rotation angle of the movable rod will be changed when the movable rod changes its angle. The movable rod passes through the outer wall of the air inlet and can scrape off impurities adhered to the filter block. The setting of the outer wall of the movable rod can effectively scrape off impurities adhered to the filter block, avoiding the adhesion of impurities and clogging the filter block. In addition, the cleaning brush will also clean the impurities on the outer wall of the filter block as it moves with the movable rod. The removal of impurities ensures that external gas can normally enter the compressed air bag, thereby ensuring the normal supply of gas.

[0021] 3. The mini emergency ventilator utilizes the fact that the rotating disk will touch the lever during rotation, thereby driving the impact block to move. After the rotating disk passes the impact block, the elasticity of the spring will drive the impact block to reset. When resetting, the impact block hits the filter block, thereby squeezing the filter block. For impurities stuck in the filter block, the impact block squeezes the impurities on the filter block to make the impurities fall off. The impact block squeezes the filter block so that some of the stuck impurities are squeezed out, and the subsequent rotation of the movable rod cleans the stuck impurities, ensuring normal gas supply, providing mechanical ventilation support for patients with dyspnea or respiratory arrest, and can effectively maintain the patient's oxygen supply to prevent serious consequences caused by respiratory failure.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] For example, see Figure 1-6 The present invention provides a technical solution: a miniature emergency ventilator, comprising a placement chamber 2, a base 3 is fixedly connected to the bottom of the placement chamber 2, a top cover 1 is rotatably connected to the top of the placement chamber 2, a connecting pipe 4 is fixedly connected to the outer wall of the placement chamber 2, a breathing mask 5 is fixedly connected to the end of the connecting pipe 4, and a breathing mechanism 6 is fixedly connected to the inner wall of the top cover 1;

[0034] The breathing mechanism 6 comprises:

[0035] A compressed air bag 62, which is fixedly connected to the inner bottom of the storage bin 2;

[0036] The top plate 63 is fixedly connected to the top of the compressed air bag 62. The descent of the top plate 63 will squeeze the gas in the compressed air bag 62, and the gas will be blown out from the breathing mask 5 through the connecting pipe 4. Then, when the first telescopic machine 61 drives the top plate 63 to rise, the external gas will enter the compressed air bag 62 through the air inlet 64. When the compressed air bag 62 is compressed and expanded, it will simulate the breathing of the human body, thereby resuscitating the normal breathing of the human body, providing mechanical ventilation support for patients with dyspnea or respiratory arrest, and effectively maintaining the oxygen supply of the patient, preventing serious consequences caused by respiratory failure, and buying precious time for subsequent medical treatment;

[0037] The first telescopic machine 61 is fixedly connected to the inner wall of the storage bin 2 , and the top of the first telescopic machine 61 is movably connected to the outer wall of the top plate 63 .

[0038] An air inlet 64 is provided at the bottom of the storage bin 2 , and a filter block 65 is fixedly connected to the inner wall of the air inlet 64 .

[0039] A groove is formed on the outer wall of the air inlet 64 , and a spring 66 is fixedly connected in the groove of the air inlet 64 .

[0040] The outer wall of the spring 66 is fixedly connected with a striking block 67 , and the outer wall of the striking block 67 is fixedly connected with a receiving rod 68 .

[0041] When in use, the top cover 1 is relatively small, and the storage compartment 2 can be directly held for walking. When it is needed, the top cover 1 is opened, and then the breathing mask 5 is put on the face of the person to be rescued, and the breathing mask 5 is connected to the compressed air bag 62 through the connecting tube 4;

[0042] Combined with Figure 5 As shown, when the first telescopic machine 61 is powered on and started, it drives the top plate 63 to descend. The descent of the top plate 63 will squeeze the gas in the compressed air bag 62, and the gas will be blown out from the breathing mask 5 through the connecting pipe 4. Then, when the first telescopic machine 61 drives the top plate 63 to rise, the external gas will enter the compressed air bag 62 through the air inlet 64.

[0043] For example 2, please refer to Figure 1-8 Based on the first embodiment, the present invention provides a technical solution:

[0044] The bottom of the storage bin 2 is fixedly connected with an auxiliary mechanism 7 , and the auxiliary mechanism 7 includes a first bearing 72 , and the first bearing 72 is fixedly connected to the bottom of the storage bin 2 .

[0045] The outer wall of the first bearing 72 is rotatably connected to the second telescopic machine 71. When the second telescopic machine 71 pulls the movable rod 73, it will pull the rotating disk 76, and the rotating disk 76 will be driven to rotate during the pulling process. Because the movable rod 73 is arranged on the rotating disk 76 away from the center of the circle through the second bearing 75, the rotating disk 76 will be driven to rotate during the pulling and pushing process of the movable rod 73 by the second telescopic machine 71. Combined with the rotation of the rotating disk 76, the rotation angle of the movable rod 73 will be changed. When the angle is changed, the movable rod 73 passes through the outer wall of the air inlet 64, and then the impurities adhered to the filter block 65 can be scraped off. The setting of the outer wall of the movable rod 73 can effectively scrape off the impurities adhered to the filter block 65, avoiding the adhesion of impurities and clogging the filter block 65. In addition, the cleaning brush 74 will also clean the impurities on the outer wall of the filter block 65 following the movement of the movable rod 73. The removal of impurities ensures that the external gas can normally enter the compressed air bag 62, ensuring the normal supply of gas. The outer wall of the second telescopic machine 71 is movably connected to the movable rod 73.

[0046] The outer wall of the movable rod 73 is fixedly connected with a cleaning brush 74, which utilizes the fact that the rotating disk 76 will touch the receiving rod 68 during rotation, thereby driving the impact block 67 to move. After the rotating disk 76 passes the impact block 67, the elasticity of the spring 66 will drive the impact block 67 to reset. When resetting, the impact block 67 hits the filter block 65, thereby squeezing the filter block 65. For impurities stuck in the filter block 65, the impact block 67 squeezes the filter block 65 to make the impurities fall. The impact block 67 squeezes the filter block 65 to squeeze some of the stuck impurities out, and cooperates with the subsequent rotation of the movable rod 73 to clean the stuck impurities, ensuring normal gas supply, providing mechanical ventilation support for patients with dyspnea or respiratory arrest, and effectively maintaining the patient's oxygen supply to prevent serious consequences caused by respiratory failure. The outer wall of the movable rod 73 is fixedly connected with a second bearing 75.

[0047] The outer wall of the second bearing 75 is rotatably connected to a rotating disk 76 , the outer wall of the rotating disk 76 is rotatably connected to a third bearing 77 , and the third bearing 77 is fixedly connected to the outer wall of the base 3 .

[0048] When in use, the second telescopic machine 71 is powered on and started to drive the movable rod 73 to move. A cleaning brush 74 is provided on the movable rod 73. When the second telescopic machine 71 pulls the movable rod 73, it will pull the rotating disk 76. During the pulling process, the rotating disk 76 will be driven to rotate. The rotation of the rotating disk 76 will change the rotation angle of the movable rod 73. When the movable rod 73 changes its angle, it passes through the outer wall of the air inlet 64, thereby scraping off impurities adhered to the filter block 65. In addition, the cleaning brush 74 follows the movement of the movable rod 73 to clean the impurities on the outer wall of the filter block 65.

[0049] Combined with Figure 7 As shown, the second telescopic machine 71 is connected to the bottom of the storage bin 2 through the first bearing 72, so when the movable rod 73 changes its angle, the second telescopic machine 71 is tilted along with the change in angle;

[0050] Combined with Figure 3 and attached Figure 2 As shown, the rotating disk 76 will touch the receiving rod 68 during the rotation process, thereby driving the impact block 67 to move. Then, after the rotating disk 76 passes the impact block 67, the elasticity of the spring 66 will drive the impact block 67 to reset. When resetting, the impact block 67 hits the filter block 65, thereby squeezing the filter block 65. For impurities stuck in the filter block 65, the impact block 67 squeezes the filter block 65 to make the impurities fall.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
