Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to a manual cardiopulmonary resuscitation device. Background Technology

[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 to 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, which significantly improves 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 allow the chest to 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] When performing artificial respiration, you should cover the victim's lips completely with your mouth, pinch the victim's nose, and blow air until the chest is lifted. The ratio of chest compression to artificial respiration is 30:2. Try to avoid pausing in compression and reassess the status every 5 cycles.

[0006] In actual operation, no medical worker can continuously and effectively complete the rescue according to the above requirements. 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.

[0007] Aiming at the above problems, the present invention provides a manual cardiopulmonary resuscitation device. SUMMARY OF THE INVENTION

[0056] If Figure 1-10 A manual cardiopulmonary resuscitation device as shown, comprising:​

[0057] The fixer comprises a bottom plate 1 and a top plate 2 arranged in parallel; a support assembly 3 is arranged on the bottom plate 1; an end of the support assembly 3 away from the bottom plate 1 passes through the top plate 2;

[0058] The presser 5 is rotatably connected to the end of the support assembly 3 away from the bottom plate 1;

[0059] The transmission device 6 comprises a first transmission arm 61, a second transmission arm 62, a transmission tooth 63, an adjustment component 64 and a conversion component 65; the middle part of the second transmission arm 62 is rotatably connected to the top plate 2; the middle part of the first transmission arm 61 is hinged to the second transmission arm 62; one end of the second transmission arm 62 away from the first transmission arm 61 is fixedly connected to the transmission tooth 63; one end of the first transmission arm 61 is plugged into the second transmission arm 62, and the other end is hinged to the presser 5; the conversion component 65 is rotatably connected to the second transmission arm 62; the middle part of the adjustment component 64 is rotatably connected to the top plate 2; one end of the adjustment component 64 abuts against the presser 5, and the other end can selectively toggle the conversion component 65 to rotate; an avoidance groove 653 is provided inside the conversion component 65, and the first transmission arm 61 is separated from the second rotating arm through the avoidance groove 653;

[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 includes 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, the mask 83 is provided with a fixing belt. 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 greatly reduces 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 makes it easier for the medical staff to press with their own weight, further saving 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 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, so as to achieve artificial respiration in the gap of chest compression, avoid the pause of compression, and enhance the treatment effect.

[0065] Preferably, the pressing rod 51 is a rod-shaped structure bent toward the bottom plate 1. The end of the pressing rod 51 away from the pressing bracket 33 is tilted toward the direction away from the bottom 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. A screw is provided at one end of the extension handle 51, and a threaded hole adapted to the screw is provided at the other end.

[0067] In some embodiments of the present application, such as Figure 1-10 As shown in FIG. 1 , 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 process of resetting 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 used to open and 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 pressure of the gas entering the patient's lungs from injuring the patient.

[0070] In the specific example of this application, such as Figure 1-10 As shown in , 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 along the transmission bracket seat to prevent the airbag 81 from deviating.

[0072] Preferably, a reset structure is provided inside the airbag 81. 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] If 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 set 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 engaged 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 presser 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 housing 641, a paddle 642, an elastic structure 643 and an adjustment arm 644; one side of the toggle housing 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 disposed between the housing 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. Push the pressing rod 51 downward, and 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 reverses, 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 disc 72 and a rack 75; the pressing disc 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 meshes 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. At this time, the transmission gear 63 drives the rack 75 to move downward, and the pressing disc 72 presses the patient's chest.

[0082] Preferably, the working device 7 further includes 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; the rack 75 is fixedly connected to the outer side wall of the sliding sleeve 73.

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

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

[0085] The plug pin 742 is detachably connected to the limit hole and the plug pin 742 is detachably connected to the positioning hole. During use, the plug pin 742 stays inside the limit hole and the positioning hole, and the rotating pin 743 hangs down. The rotating pin 743 and the enlarged structure 741 are on both sides of the plug pin 742 respectively to prevent the plug pin 742 from being displaced.

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

[0087] A limit hole is provided inside the support assembly 3, and the pressing rod 51 passes through the support assembly 3 through the limit hole. The function of the limit hole is to limit the movement angle of the pressing rod 51 to prevent the pressing disc 72 from pressing the patient's chest too deeply and preventing damage to the patient's ribs.

[0088] Preferably, the movable support 52 is hinged to the actuator 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 support 52. The rotating shaft moves inside the sliding groove.

[0089] As Figure 1-10 As shown, the support assembly 3 includes a fixed support column 31, a rotating bracket 32 and a pressing bracket 33; one end of the rotating bracket 32 is rotatably connected to the fixed support column 31, and the other end is fixedly connected to the pressing bracket 33.

[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 on the side away from the fixed support column 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 some other embodiments of the present application, the sound generator 321 is hinged to the rotating bracket 32. When the sliding bracket 52 rises, it will gradually move towards 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 upwards. 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, first drive the top plate 2 to rotate to expose the bottom plate 1, so as to facilitate inserting the bottom plate 1 under the patient; then reverse the top plate 2 so that the top plate 2 coincides with the bottom plate 1. At this time, the pressing disc 72 is aligned with the patient's chest, and the pressing part can be driven to start cardiopulmonary resuscitation operations.

[0094] Furthermore, the fixator further 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. An insertion 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 insertion hole.
