Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a manual cardiopulmonary resuscitation device. Background Art

[0002] Cardiopulmonary resuscitation, or CPR for short, is a life-saving technique for cardiac and respiratory arrest. It is designed to restore the patient's spontaneous breathing and circulation. It is a series of rescue measures that establish more effective ventilation and blood circulation through artificial chest compression, opening of airways, artificial respiration, and the use of auxiliary equipment and special techniques, so as to promptly reconstruct and promote the effective recovery of cardiac and respiratory functions for patients who have suffered respiratory and cardiac arrest due to various reasons such as trauma, disease, poisoning, accidental hypothermia, drowning or electric shock, and significantly improve the survival rate and long-term prognosis of patients with cardiac arrest.

[0003] For patients without pulse, chest compressions should be performed immediately. The rescuer is usually on the right side of the patient, with the base of the left palm placed on the lower middle section of the patient's sternum, and the right palm pressed on the back of the left hand and pressed down. Use the palm, shoulder, and elbow to press more than 100 times per minute, the compression depth should be 4-6cm, and each compression should make the chest rebound and recover.

[0004] During CPR, it is very important to open the airway, especially for patients with foreign bodies in the airway. Place your left hand on the patient's forehead, press back with your left hand, place your right hand fingers on the edge of the patient's jaw, lift the head up and forward, and let the patient look up. The rescuer should completely seal the outside of the patient's mouth with his lips and blow air into the patient's mouth at a uniform speed.

[0005] Artificial respiration should be done by covering the victim's lips completely with your mouth, pinching the victim's nose, and blowing air until the chest is lifted. The ratio of chest compression to artificial respiration is 30:2. Pauses in compression should be avoided as much as possible, and the status should be reassessed every 5 cycles.

[0006] In actual operation, no medical worker can continuously and effectively complete the rescue according to the above requirements, and it is often necessary for multiple people to perform chest compressions alternately, which easily leads to irregular compressions, insufficient compression depth and other non-standard operations. In addition, many patients often die suddenly at night, and the physical strength of the medical staff on duty is not enough to support the entire rescue process, which is bound to cause adverse consequences and greatly reduce the efficiency of rescue.

[0060] The working device 7 passes through the top plate 2 and is slidably connected to the top plate 2; the working device 7 is meshed with the transmission gear 63;

[0061] The respirator 8 comprises an air bag 81 , a connecting tube 82 and a mask 83 ; the air bag 81 is arranged at one end of the top plate 2 away from the bottom plate 1 ; one end of the connecting tube 82 is connected to the air bag 81 , and the other end is connected to the mask 83 .

[0062] Specifically, a fixing belt is provided on the mask 83. When in use, the mask 83 is wrapped around the patient's mouth, and the fixing belt is used to fix the mask 83 on the patient's face.

[0063] The two-stage lever-type labor-saving structure composed of the presser 5 and the transmission device 6 can greatly reduce the physical exertion of medical staff; when the medical staff drives the presser 5 downward, the working device 7 presses the patient's chest synchronously, which is convenient for the medical staff to use their own body weight to press and further save physical exertion.

[0064] In the process of driving the compressor 5, the adjustment component 64 drives the conversion component 65 to rotate; when the avoidance groove 653 is not aligned with the first transmission arm 61, the first transmission arm 61 is restricted by the conversion component 65 inside the second rotating arm, so that the second rotating arm moves with the compressor 5, driving the working part to press the patient's chest to achieve external chest compression; when the avoidance groove 653 is aligned with the first transmission arm 61, the first transmission arm 61 can be separated from the second transmission arm 62 through the avoidance groove 653, so that the first transmission arm 61 presses the airbag 81, and the gas inside the airbag 81 enters the patient's mouth through the connecting tube 82 and the mask 83, and finally enters the lungs through the patient's trachea, thereby achieving artificial respiration in the gaps between external chest compressions, avoiding pauses in compression, and enhancing the treatment effect.

[0065] Preferably, the pressing rod 51 is a rod-shaped structure bent in the direction of the base plate 1. The end of the pressing rod 51 away from the pressing bracket 33 is tilted in the direction away from the base plate 1, and a plurality of extension handles 511 are provided at the end of the pressing rod 51 away from the pressing bracket 33. The extension handles 511 are detachably connected to the pressing rod 51. Adjacent extension handles 511 are also detachably connected. By installing different numbers of extension handles 51 on the pressing rod 51, the total length of the pressing rod 51 and the extension handles 511 and the height of the last extension handle 51 can be adjusted to accommodate medical staff of different heights.

[0066] Specifically, the extension handle 511 is threadedly connected to the pressing rod 51. One end of the extension handle 51 is provided with a screw rod, and the other end is provided with a threaded hole adapted to the screw rod.

[0067] In some embodiments of the present application, Figure 1-10 As shown, a one-way valve is provided inside the connecting tube 82, and an air inlet valve is provided on the airbag 81. When the first transmission arm 61 presses the airbag 81, the gas inside the airbag 81 flows along the connecting tube 82 and passes through the one-way valve and finally enters the patient's lungs through the mask 83. The purpose of this design is:

[0068] During the resetting process of the airbag 81, the one-way valve prevents the patient's exhaled gas from flowing back into the airbag 81 through the connecting tube 82, resulting in a decrease in the amount of oxygen entering the patient's lungs next time, thereby ensuring the treatment effect.

[0069] Preferably, a regulating valve 84 is provided on the airbag 81. The regulating valve 84 is opened to release air when the internal pressure of the airbag 81 is too high, so as to control the internal pressure of the airbag 81 and prevent the excessive gas pressure entering the patient's lungs from injuring the patient.

[0070] In the specific example of this application, Figure 1-10 As shown, a transmission bracket is provided on one side of the top plate 2 away from the bottom edge; the second transmission arm 62 is rotatably connected to the transmission bracket.

[0071] A push plate is provided on the top of the airbag 81; the push plate reciprocates linearly along the transmission bracket seat to prevent the airbag 81 from deviating.

[0072] Preferably, a reset structure is provided inside the airbag 81 , and when the first transmission arm 61 no longer presses the push plate, the reset structure returns to its original shape and pushes the airbag 81 to expand, waiting for the next pressing of the airbag 81 .

[0073] Specifically, the reset structure is a linear compression spring.

[0074] like Figure 1-10 As shown, the conversion assembly 65 includes a fixed plate 651 and an adjustment plate 652; one end of the fixed plate 651 is fixedly connected to the second transmission arm 62, and the other end is rotatably connected to the adjustment plate 652; the avoidance groove 653 is provided on the adjustment plate 652. The adjustment assembly 64 drives the adjustment plate 652 to rotate; when the avoidance groove 653 is not aligned with the first transmission arm 61, the first transmission arm 61 keeps synchronous movement with the second rotating arm, driving the second rotating arm to drive the working part to press the patient's chest, thereby achieving chest compression.

[0075] When the avoidance groove 653 is aligned with the first transmission arm 61, the first transmission arm 61 can be separated from the second transmission arm 62 through the avoidance groove 653. At this time, the working device 7 is pressed against the patient's chest, so that the working device 7 remains motionless. The working device 7 is meshed with the transmission tooth 63, and the working device 7 does not move, which restricts the transmission tooth 63 and the second transmission arm 62 to remain motionless; at this time, the first transmission arm 61 can rotate and press the airbag 81 under the drive of the pressing device 5.

[0076] Ratchets are provided at the edge of the adjustment disk 652. Specifically, the number of ratchets is 32, and the area of ​​the avoidance groove 653 is 1 / 16 of the adjustment disk 652, so as to realize a cycle with a ratio of 30:2 between chest compression and artificial respiration.

[0077] In the specific example of the present application, the adjustment component 64 includes a toggle shell 641, a paddle 642, an elastic structure 643 and an adjustment arm 644; one side of the toggle shell 641 is fixedly connected to the adjustment arm 644, and the other side is rotatably connected to the paddle 642; the elastic structure 643 is arranged between the shell and the paddle 642.

[0078] One end of the adjustment arm 644 abuts against the presser 5, and the middle part is rotatably connected to the top plate 2; the paddle 642 can selectively toggle the conversion assembly 65 to rotate. When the pressing rod 51 is pushed downward, the movable bracket 52 drives the adjustment arm 644 to rotate, so that the paddle 642 contacts the ratchet and pushes the adjustment disk 652 to rotate 11.25°; when the pressing rod 51 is reversed, the adjustment arm 644 reverses with the pressing rod 51 under the influence of its own gravity, and the paddle 642 contacts the reverse side of the ratchet and is pressed into the shell by the ratchet. At this time, the paddle 642 will not drive the adjustment disk 652 to rotate.

[0079] Preferably, the elastic structure 643 is a spring.

[0080] Specifically, the elastic structure 643 is a torsion spring.

[0081] In some examples of the present application, the working device 7 includes a push rod 71, a pressing plate 72 and a rack 75; the pressing plate 72 is arranged at one end of the push rod 71; the rack 75 is arranged on the side wall of the push rod 71. The push rod 71 passes through the top plate 2 and is slidably connected to the top plate 2; the rack 75 is meshed with the transmission gear 63. When the pressing rod 51 is pressed, the movable bracket 52 drives the first transmission arm 61 and the second transmission arm 62 to rotate, and at this time the transmission gear 63 drives the rack 75 to move downward, and the pressing plate 72 presses the patient's chest.

[0082] Preferably, the working device 7 further comprises a sliding sleeve 73 ; the sliding sleeve 73 passes through the top plate 2 and is slidably connected to the top plate 2 ; the push rod 71 is detachably connected to the sliding sleeve 73 ; and the rack 75 is fixedly connected to the outer wall of the sliding sleeve 73 .

[0083] Furthermore, the push rod 71 is connected to the sliding sleeve 73 through a control assembly 74. The push rod 71 is provided with at least two limiting holes; the plurality of limiting holes are regularly arranged along the axis of the push rod 71. The sliding sleeve 73 is provided with a positioning hole; the control assembly 74 is detachably connected to the limiting hole, and the control assembly 74 is detachably connected to the positioning hole. By aligning different limiting holes with the positioning hole, the pressing depth of the pressing plate 72 can be adjusted to suit different patients.

[0084] Preferably, the control assembly 74 includes an expanded structure 741, a latch 742 and a rotating pin 743; the latch 742 is rotatably connected to the rotating pin 743, and the other end is fixedly connected to the expanded structure 741. When the latch 742 passes through the positioning hole, the rotating pin 743 naturally droops under the action of gravity.

[0085] The latch 742 is detachably connected to the limiting hole, and the latch 742 is detachably connected to the positioning hole. When in use, the latch 742 stays inside the limiting hole and the positioning hole, and the rotating pin 743 droops. The rotating pin 743 and the expanded structure 741 are respectively on both sides of the latch 742 to prevent the latch 742 from being offset.

[0086] like Figure 1-10 As shown, the presser 5 includes a press rod 51 and a movable bracket 52 ; the press rod 51 passes through the support assembly 3 and is fixedly connected to the movable bracket 52 ; the press rod 51 is rotatably connected to the support assembly 3 .

[0087] A limiting hole is provided inside the support assembly 3, and the pressing rod 51 passes through the supporting assembly 3 through the limiting hole. The limiting hole is used to limit the movement angle of the pressing rod 51 to prevent the pressing plate 72 from excessively pressing the patient's chest and preventing the patient's ribs from being damaged.

[0088] Preferably, the movable bracket 52 is hinged to the transmission device 6. Specifically, a rotating shaft is provided at one end of the first transmission arm 61 away from the second transmission arm 62, and a sliding groove is provided inside the movable bracket 52. The rotating shaft moves inside the sliding groove.

[0089] like Figure 1-10 As shown, the support assembly 3 includes a fixed support 31, a rotating bracket 32 ​​and a pressing bracket 33; one end of the rotating bracket 32 ​​is rotatably connected to the fixed support 31, and the other end is fixedly connected to the pressing bracket 33. One end of the fixed support 31 is fixedly connected to the bottom plate 1, and the other end is rotatably connected to the rotating bracket 32 ​​and the top plate 2 respectively.

[0090] Specifically, the limiting hole is provided on the rotating bracket 32 ​​.

[0091] Preferably, a sound generator 321 is provided inside the rotating bracket 32, and the sound generator 321 is located on the inner wall of the limiting hole away from the fixed support 31. When the sliding bracket 52 rises, it will hit the generator 321 and make a sound to remind the operator that an effective press has been completed.

[0092] In other embodiments of the present application, the sound generator 321 is hinged to the rotating bracket 32. When the sliding bracket 52 is raised, it will gradually move toward the sound generator 321 until it contacts the sound generator 321. When the sliding bracket 52 contacts the sound generator 321, it will drive the sound generator 321 to rotate upward. Then the sliding bracket 52 reverses, and the sound generator 321 will drop under the action of gravity and knock on the inner wall of the rotating bracket, making a sound to remind the operator.

[0093] During use, the top plate 2 is first rotated to expose the bottom plate 1, so as to facilitate the insertion of the bottom plate 1 under the patient; then the top plate 2 is reversed so that the top plate 2 overlaps with the bottom plate 1. At this time, the pressing plate 72 is aligned with the patient's chest, and the pressing part is driven to start the cardiopulmonary resuscitation operation.

[0094] Furthermore, the fixer also includes a limiting component 4; one end of the limiting component 4 is hinged to the top plate 2, and the other end is detachably connected to the bottom plate 1.

[0095] Specifically, a limiting platform 11 is provided on the bottom plate 1, and the limiting platform 11 protrudes above the bottom plate 1. A plug hole is provided inside the limiting platform 11. One end of the limiting component 4 away from the top plate 2 is inserted into the plug hole.

[0096] The function of the limit component 4 is:

[0097] 1. Prevent the top plate 2 from rotating around the fixed support 31 to ensure that the top plate 2 overlaps with the bottom plate 1;

[0098] 2. Prop up the top plate 2 to prevent it from collapsing during cardiopulmonary resuscitation, thereby affecting the treatment effect.

[0099] Specifically, the limiting assembly 4 includes a telescopic rod.
