Description

Technical Field

[0001] This invention belongs to the field of medical equipment technology, specifically a cardiopulmonary resuscitation device for emergency rescue. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) equipment is a commonly used medical device by medical personnel in the emergency treatment of comatose patients. Using CPR equipment can reduce the burden on medical staff, improve the success rate of cardiac resuscitation, reduce the margin of error for medical personnel, prevent excessive force leading to rib fractures, and prevent insufficient force from failing to deliver blood to the patient's body. However, existing CPR equipment requires adjustment of the chest compression block according to the patient's body size before actual use. This cumbersome adjustment process leads to a long preparation time, reducing the equipment's efficiency. Furthermore, since comatose patients lack spontaneous breathing awareness, even with CPR equipment, they can only exhale effectively, but the oxygen supply is insufficient, reducing the effectiveness of the rescue. Therefore, this paper proposes an emergency CPR device. Summary of the Invention

The top end of the mounting rod passes through the connecting cylinder and extends above the connecting cylinder, and is fixedly connected to a movable plate. A limit rod is fixedly connected to the top of the pressing controller. The top end of the limit rod passes through the movable plate and extends above the movable plate. The outer surface of the limit rod is movably sleeved with the inside of the movable plate.

[0007] Preferably, a fan is fixedly installed on the top of the press controller, an installation pipe is fixedly connected to the left side of the fan, and the other end of the installation pipe is fixedly connected to the top of the connecting cylinder.

[0008] Preferably, a corrugated hose is fixedly connected to the bottom of the connecting cylinder, and a face mask is fixedly connected to the other end of the corrugated hose. Connecting straps are fixedly connected to both the front and back sides of the face mask.

[0009] Preferably, a movable groove 1 is provided at the rear of the top of the pad, and a movable groove 2 is provided at the front of the top of the pad. Movable wheels 1 are movably installed on both sides inside the movable groove 1, and movable wheels 2 are movably installed at the bottom inside the movable groove 1.

[0010] Preferably, the other end of the connecting belt passes through the movable groove one and extends below the movable wheel two through the movable wheel one and the movable wheel two, and is fixedly connected to a fixing plate. The top of the fixing plate passes through the pad and extends above the pad and is fixedly connected to the bottom of the movable plate. The fixing plate is movably sleeved inside the movable groove two.

[0011] Preferably, the piston 2 has an air hole inside, a baffle is movably connected to the bottom of the piston 2, a movable rod is fixedly connected to the top of the baffle, the top of the movable rod passes through the piston 2 and extends to the top of the piston 2 and is fixedly connected to a connecting block, a spring is sleeved on the outer surface of the movable rod, a spring is provided on the top of the piston 2 and the connecting block is elastically supported by the spring.

[0012] Preferably, a connecting plate is fixedly installed inside the mask, a one-way valve one is fixedly installed inside the other end of the corrugated hose, an air outlet pipe is fixedly connected to the right side of the top of the mask, a one-way valve two is fixedly installed inside the air outlet pipe, a ventilation pipe is fixedly connected to the bottom of the connecting plate, a round pipe is fixedly connected to the right side of the top of the inner cavity of the mask, and the other end of the round pipe is fixedly connected to the top of the connecting plate.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This invention, by setting up a connecting rod, a connecting pipe, and a connecting tube, allows the oil pump to deliver oil from the lower part of the cylinder to the upper part of the cylinder through the connecting pipe, causing the piston to move downwards. The movement of the piston causes the connecting rod, the pressing controller, and the pressure block to move downwards. When the bottom of the pressure block contacts the patient's chest, it blocks the light source below the optical sensor. The optical sensor then controls the pressing controller to stop the oil pump, stopping the pressing controller's descent and simultaneously starting the fan. This operation significantly reduces the preparation time for medical personnel before using the cardiopulmonary resuscitation (CPR) device, while also improving the device's rescue efficiency.

[0015] 2. This invention, by setting up piston two, mounting rod and connecting belt, allows a large amount of air to be sent into the interior of the connecting cylinder through the installation pipe due to the operation of the fan, thereby pressurizing piston two and causing it to move downward. Due to the movement of piston two, the mounting rod can drive the movable plate and fixed plate to move downward along the outer surface of the limiting rod. Due to the movement of the fixed plate, the connecting belt can move downward through movable wheel one and movable wheel two, thereby contracting the connecting belt and tightening the mask on the patient's face. This allows the mask to be quickly and securely worn on the patient, saving medical staff the time of adjusting the size of the connecting belt.

[0016] 3. This invention, by setting up a corrugated hose, a ventilation tube, and air vents, allows the piston two to stop moving downwards when the mask is tightened on the patient's face. As the air pressure inside the connecting cylinder increases, air will squeeze the baffle downwards through the air vents. Due to the movement of the baffle, the baffle, the movable rod, and the connecting block can move downwards. At this time, the spring is compressed, and the air inside the connecting cylinder enters the corrugated hose through the air vents. When the one-way valve one is squeezed open, air can enter the ventilation tube and be delivered to the patient's lungs, thereby increasing the oxygen supply to the patient and ensuring sufficient oxygen supply when breathing stops. This also improves the rescue effect of the device. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 9As shown, this embodiment of the invention provides a cardiopulmonary resuscitation device for emergency rescue, including a pad 1, a support block 2 fixedly connected to the front of the pad 1, a hydraulic cylinder 3 fixedly installed inside the support block 2, a piston 4 movably sleeved inside the hydraulic cylinder 3, a connecting rod 5 fixedly connected to the top of the piston 4, the top end of the connecting rod 5 penetrating the support block 2 and extending above the support block 2 and fixedly connected to a pressing controller 6, the outer surface of the connecting rod 5 movably sleeved with the inside of the support block 2, an oil pump 7 fixedly installed on the left side inside the support block 2, a connecting pipe 9 fixedly connected to the right side of the oil pump 7, the other end of the connecting pipe 9 fixedly connected to the left side of the hydraulic cylinder 3, a connecting pipe 8 fixedly connected to the top of the oil pump 7, the other end of the connecting pipe 8 fixedly connected to the upper left side of the hydraulic cylinder 3, a fixing rod 10 movably installed at the rear of the bottom of the pressing controller 6, a pressure block 11 fixedly connected to the bottom end of the fixing rod 10, and an optical sensor 12 fixedly installed in the inner wall of the bottom of the pressure block 11.

[0029] During use, the operation of the oil pump 7 allows the oil from the bottom of the cylinder 3 to be fed into the upper part of the cylinder 3 via the connecting pipe 8 through the connecting pipe 9, which in turn drives the piston 4 to move downwards. The movement of the piston 4 drives the connecting rod 5, the pressing controller 6, and the pressing block 11 to move downwards. When the bottom of the pressing block 11 moves to contact the patient's chest, the light source below the optical sensor 12 is blocked, the oil pump 7 stops running, and the pressing controller 6 stops descending. This operation can greatly shorten the preparation time for medical staff before using the cardiopulmonary resuscitation equipment.

[0030] As the pressure controller 6 operates, it can drive the pressure block 11 and the optical sensor 12 to repeatedly press the patient's chest, thereby causing the patient's chest cavity to rise and fall and breathe, while also causing the patient's heart to rise and fall and pumping blood into the whole body.

[0031] like Figure 1 and Figure 3 As shown, in one embodiment, a connecting cylinder 13 is fixedly installed on the back of the press controller 6, a piston 14 is movably sleeved inside the connecting cylinder 13, a tension spring 15 is fixedly connected to the top of the piston 14, and the other end of the tension spring 15 is fixedly connected to the top of the inner cavity of the connecting cylinder 13.

[0032] The working principle and beneficial effects of the above technical solution are as follows: When the internal air pressure of the connecting cylinder 13 increases, the piston 14 will move downward and the tension spring 15 will be stretched. Due to the elastic recovery effect of the tension spring 15, the piston 14 can be subjected to an upward pulling force, so as to facilitate the subsequent reset effect of the piston 14.

[0033] like Figure 1 , Figure 3 and Figure 5As shown, in one embodiment, a mounting rod 18 is fixedly connected to the right side of the top of the piston 2 14. The top end of the mounting rod 18 passes through the connecting cylinder 13 and extends above the connecting cylinder 13 and is fixedly connected to the movable plate 20. A limit rod 19 is fixedly connected to the top of the pressing controller 6. The top end of the limit rod 19 passes through the movable plate 20 and extends above the movable plate 20. The outer surface of the limit rod 19 is movably sleeved with the inside of the movable plate 20.

[0034] The working principle and beneficial effects of the above technical solution are as follows: When the piston 14 moves downward, the mounting rod 18 can drive the movable plate 20 to move downward along the outer surface of the limiting rod 19, and at the same time, the limiting rod 19 can play a good limiting effect on the movable plate 20.

[0035] like Figure 3 As shown, in one embodiment, a fan 16 is fixedly installed on the top of the press controller 6, and an installation pipe 17 is fixedly connected to the left side of the fan 16. The other end of the installation pipe 17 is fixedly connected to the top of the connecting cylinder 13.

[0036] The working principle and beneficial effects of the above technical solution are as follows: A fan 16 is set up. Due to the operation of the fan 16, a large amount of air can be sent into the interior of the connecting cylinder 13 through the installation pipe 17, thereby pressurizing the piston 14, which can drive the piston 14 to move downward and provide good driving force to the piston 14.

[0037] like Figure 3 and Figure 5 As shown, in one embodiment, a corrugated hose 21 is fixedly connected to the bottom of the connecting tube 13, and a face mask 22 is fixedly connected to the other end of the corrugated hose 21. Connecting straps 24 are fixedly connected to both the front and rear sides of the face mask 22.

[0038] The working principle and beneficial effects of the above technical solution are as follows: a corrugated hose 21 and a mask 22 are set up. When the mask 22 is tightened on the patient's face, the air inside the connecting tube 13 can enter the inside of the mask 22 through the corrugated hose 21, and at the same time, it can be delivered into the patient's lungs through the mask 22, thereby increasing the oxygen supply in the patient's body.

[0039] like Figure 8 and Figure 9 As shown, in one embodiment, a movable groove 23 is provided at the rear of the top of the pad 1, and a movable groove 29 is provided at the front of the top of the pad 1. Movable wheels 25 are movably installed on both sides inside the movable groove 23, and movable wheels 26 are movably installed at the bottom inside the movable groove 23.

[0040] The working principle and beneficial effects of the above technical solution are as follows: by setting up movable wheel 1 25 and movable wheel 26, the movable wheel 1 25 and movable wheel 26 can have good mobility inside the movable groove 1 23 due to their design, thereby improving the mobility of the connecting belt 24 inside the movable groove 1 23.

[0041] like Figure 8 and Figure 9 As shown, in one embodiment, the other end of the connecting belt 24 passes through the movable groove 23 and extends through the movable wheel 25 and the movable wheel 26 to the bottom of the movable wheel 26 and is fixedly connected to a fixing plate 28. The top of the fixing plate 28 passes through the pad 1 and extends to the top of the pad 1 and is fixedly connected to the bottom of the movable plate 20. The fixing plate 28 is movably sleeved inside the movable groove 29.

[0042] The working principle and beneficial effects of the above technical solution are as follows: When the movable plate 20 moves downward, the movable plate 20 can drive the fixed plate 28 and the connecting belt 24 to move downward through the movable wheel 1 25 and the movable wheel 26, thereby shrinking the connecting belt 24 and tightening the mask 22 on the patient's face.

[0043] like Figure 3 and Figure 4 As shown, in one embodiment, the piston 2 14 has an air hole 30 inside, a baffle 31 is movably connected to the bottom of the piston 2 14, a movable rod 32 is fixedly connected to the top of the baffle 31, the top end of the movable rod 32 passes through the piston 2 14 and extends to the top of the piston 2 14 and is fixedly connected to a connecting block 33, a spring 34 is sleeved on the outer surface of the movable rod 32, the top of the piston 2 14 is provided with a spring 34 and the connecting block 33 is elastically supported by the spring 34.

[0044] The working principle and beneficial effects of the above technical solution are as follows: When the piston 14 stops moving, the air pressure inside the connecting cylinder 13 will squeeze the baffle 31 downward through the air hole 30. Due to the movement of the baffle 31, the baffle 31, the movable rod 32 and the connecting block 33 can move downward. At this time, the spring 34 is compressed, and the air inside the connecting cylinder 13 enters the interior of the corrugated hose 21 through the air hole 30.

[0045] like Figure 6 and Figure 7As shown, in one embodiment, a connecting plate 38 is fixedly installed inside the mask 22, a one-way valve 35 is fixedly installed inside the other end of the corrugated hose 21, an air outlet pipe 36 is fixedly connected to the right side of the top of the mask 22, a one-way valve 37 is fixedly installed inside the air outlet pipe 36, a ventilation pipe 27 is fixedly connected to the bottom of the connecting plate 38, and a round pipe 39 is fixedly connected to the right side of the top of the inner cavity of the mask 22, with the other end of the round pipe 39 fixedly connected to the top of the connecting plate 38.

[0046] The working principle and beneficial effects of the above technical solution are as follows: When the air tube 27 is set up, when the one-way valve 35 is squeezed open by the corrugated hose 21, air can enter the interior of the air tube 27 and be delivered to the patient's lungs to increase the oxygen supply in the patient's body. When the patient exhales carbon dioxide, a large amount of carbon dioxide can be exhaled into the interior of the round tube 39 through the air tube 27. Finally, the one-way valve 37 can be squeezed open and the carbon dioxide can be discharged to the outside through the exhaust tube 36.

[0047] Working principle and usage process:

[0048] In use, medical staff place the patient on top of pad 1, then place mask 22 on the patient's face, and insert ventilation tube 27 into the patient's mouth. Then, the oil pump 7 is activated, and oil from the lower part of cylinder 3 is pumped through connecting pipe 9 and connecting pipe 8 to the upper part of cylinder 3, causing piston 4 to move downwards. The movement of piston 4 causes connecting rod 5, press controller 6, and pressure block 11 to move downwards. When the bottom of pressure block 11 contacts the patient's chest, the light source below optical sensor 12 is blocked. Optical sensor 12 then controls press controller 6 to stop oil pump 7, stopping press controller 6 from descending and simultaneously activating fan 16. The operation of fan 16 sends a large amount of air into connecting cylinder 13 through mounting pipe 17, thus pressurizing piston 14 and causing it to move downwards. As piston 14 moves downward, the mounting rod 18 drives the movable plate 20 and the fixed plate 28 to move downward along the outer surface of the limiting rod 19. Due to the movement of the fixed plate 28, the connecting belt 24 moves downward through the movable wheel 25 and the movable wheel 26, thereby retracting the connecting belt 24 and tightening the mask 22 on the patient's face. At this time, piston 14 will be blocked from moving downward. As the air pressure inside the connecting cylinder 13 increases, air will squeeze the baffle 31 downward through the air hole 30. Due to the movement of the baffle 31, the baffle 31, the movable rod 32 and the connecting block 33 can move downward. At this time, the spring 34 is compressed, and the air inside the connecting cylinder 13 enters the corrugated hose 21 through the air hole 30. When the one-way valve 35 is squeezed open, air can enter the ventilation tube 27 and be delivered to the patient's lungs.

[0049] As the compression controller 6 operates, it can drive the compression block 11 and the optical sensor 12 to repeatedly compress the patient's chest, thereby causing the patient's chest cavity to rise and fall and breathe, while also causing the patient's heart to rise and fall and pumping blood throughout the body. When the chest cavity is compressed, the patient's lungs will exhale carbon dioxide. At this time, a large amount of carbon dioxide is exhaled into the round tube 39 through the ventilation tube 27. Finally, the one-way valve 37 can be squeezed open, and carbon dioxide is discharged to the outside through the exhaust tube 36. When the chest cavity is released, sufficient oxygen can be delivered into the patient's body through the ventilation tube 27.
