Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a cardiopulmonary resuscitation pressing device for emergency critically ill patients. Background Art

[0002] Cardiopulmonary resuscitation is an emergency measure for sudden cardiac and respiratory arrest. It can restore the patient's spontaneous breathing and circulation. If cardiac arrest cannot be effectively rescued and resuscitated within 4 to 6 minutes, it will cause irreversible damage to the patient's brain and other important organs and tissues. Therefore, cardiopulmonary resuscitation after cardiac arrest must be performed immediately on the spot.

[0003] Different treatment methods are used for cardiac arrest caused by different reasons. If the patient's cardiac arrest is caused by malignant arrhythmias such as pulseless ventricular tachycardia or ventricular fibrillation, AED defibrillation is required first to terminate the occurrence of malignant arrhythmias, thereby helping the patient to restore normal heartbeat. Then chest compressions should be performed continuously to increase the patient's chance of resuscitation. If the patient's cardiac arrest is caused by drowning, suffocation, etc., chest compressions should be performed directly. AEDs are ineffective for respiratory and cardiac arrest caused by such reasons. It can be seen that chest compressions are an indispensable means of cardiopulmonary resuscitation. Chest compressions require continuous reciprocating squeezing force on the patient's chest cavity. This process consumes a lot of the operator's physical strength. With the help of a cardiopulmonary resuscitation compression device, the operator's physical strength can be greatly saved. However, this type of CPR compression device needs to adjust the compression position before performing chest compression on the patient. When non-medical personnel use the above device to perform chest compression on the patient, it is difficult to ensure the accuracy of the compression position, resulting in limited cardiopulmonary resuscitation effect on the patient. Inaccurate compression position may even cause rib injuries to the patient.

[0004] For example, Chinese invention patent CN113768775B specifically discloses a cardiopulmonary resuscitation pressing device, wherein the driving wheel drives the belt to rotate, the belt drives the driven wheel to rotate, the screw rotates with the driven wheel, the screw rotates and moves downward along the support rod, the screw drives the housing to move downward, the vertical rod moves downward with the housing, and the pressing block at the lower end of the vertical rod moves toward the child patient with the vertical rod to perform chest compression on the child patient. Before use, the curved surface of the housing needs to be manually adjusted so that the adjusted curved surface of the housing is buckled on the child patient who needs cardiopulmonary resuscitation compression, so that the pressing block in the housing is placed directly above the pressing position. Due to the different body shapes of different children, the pressing position on the child's body is different relative to the initial position of the shell. Therefore, the adjustment distance of the shell is different. By manually adjusting the position of the shell, it is difficult to ensure the accuracy of the final pressing position of the pressing block when performing cardiopulmonary resuscitation on different children. Another example is China's invention patent CN110393663B, which specifically discloses a cardiopulmonary resuscitation chest compression device, which drives the vertical rod to move downward by rotating the cam, and the vertical rod moves downward to compress the first wedge block downward. The first wedge block causes the pressing block to press the human body downward through the pressure rod to perform chest compression on the patient. It can be seen from the method of use disclosed in its specification that when using it, the patient must first be placed flat on the ground, and then the device is placed above the patient, and the pressing block is placed in a suitable position on the patient's body. The pressing block is driven by the first wedge block to press the patient's chest. When using it, the pressing position of the pressing block must be manually adjusted first, and the above-mentioned problem of difficulty in ensuring the accuracy of the pressing position of the pressing block also exists.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-Figure 6 , the specific implementation of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 6As shown, the cardiopulmonary resuscitation pressing device for emergency critically ill patients provided by the present invention includes a bottom plate 103, a pressing mechanism 102, a left push plate 104 and a right push plate 105, the left push plate 104 and the right push plate 105 are respectively arranged on the left and right sides of the bottom plate 103, and also includes: a detection unit and a driving mechanism 106, the detection unit is arranged on the left push plate 104 and the right push plate 105, the detection unit is used to detect the real-time pressure exerted on the left push plate 104 or the right push plate 105 when the left push plate 104 or the right push plate 105 contacts the patient's body; the driving mechanism 106 is connected to the left push plate 104, the right push plate 105 and the detection unit, and the driving mechanism 106 The left push plate 104 is synchronously driven to move rightward and the right push plate 105 is driven to move leftward. When the real-time pressures on the left push plate 104 and the right push plate 105 are not zero, the driving mechanism 106 stops driving. The left push plate 104 and the right push plate 105 are symmetrically arranged relative to the pressing mechanism 102. Both the left push plate 104 and the right push plate 105 are provided with through holes 5. After the patient's left arm passes through the through hole 5 on the left push plate 104, the through hole 5 on the left push plate 104 positions the patient's left shoulder. After the patient's right arm passes through the through hole 5 on the right push plate 105, the through hole 5 on the right push plate 105 positions the patient's right shoulder.

[0031] The working principle of the above embodiment is briefly described:

[0032] When the device is in use, the patient is placed between the left push plate 104 and the right push plate 105 on the base plate 103, and the patient's body width is kept in the same direction as the width direction of the base plate 103. The patient's left arm passes through the through hole 5 on the left push plate 104, and the edge of the through hole 5 abuts against the patient's left shoulder. The patient's left shoulder is positioned using the through hole 5 on the left push plate 104. The patient's right arm passes through the through hole 5 on the right push plate 105, and the edge of the through hole 5 abuts against the patient's right shoulder. The patient's right shoulder is positioned using the through hole 5 on the push plate on the right push plate 105. Under the positioning action of the through holes 5 on the left push plate 104 and the through holes 5 on the right push plate 105, the position of the pressing mechanism 102 relative to the length direction of the patient's body can be positioned to ensure the accuracy of the pressing position of the pressing mechanism 102. Then, the driving mechanism 106 is controlled to move, and the driving mechanism 106 drives the left push plate 104 and the right push plate 105 to move synchronously toward each other along the width direction of the bottom plate 103. When the patient's chest cavity deviates to the left side of the pressing mechanism 102, the left push plate 104 is driven by the driving mechanism 106 to first contact the left side of the patient's body, and the left push plate 104 applies a thrust toward the right side of the patient's body to the patient's body to push the patient's body to move to the right side, thereby adjusting the patient's body position until the patient's body contacts the right push plate 105. At this time, the patient's body is restricted to the left push plate 104. 04 and the right push plate 105. Since the left push plate 104 and the right push plate 105 are symmetrical with respect to the pressing mechanism 102, when the patient's body is confined between the left push plate 104 and the right push plate 105, the pressing mechanism 102 located between the left push plate 104 and the right push plate 105 is located directly above the patient's chest. When the patient's chest is deviated to the left side of the pressing mechanism 102, the right push plate 105 is first abutted against the right side of the patient's body under the drive of the driving mechanism 106. Similarly, the patient's body can still be confined between the left push plate 104 and the right push plate 105. Then, the pressing mechanism 102 is controlled to move, and the pressing mechanism 102 is used to reciprocately press the patient's chest, thereby performing cardiopulmonary resuscitation on the patient.

[0033] The cardiopulmonary resuscitation pressing device for emergency critically ill patients of the present invention can adjust the patient's body position before performing cardiopulmonary resuscitation pressing on patients of different body sizes to ensure accurate pressing of the patient's chest cavity, and when pressing the patient's chest cavity, it limits the patient's body shaking to prevent the patient's body from shifting, ensuring that only the patient's chest cavity is pressed during the entire cardiopulmonary resuscitation process, thereby ensuring the effect of the patient's cardiopulmonary resuscitation and preventing the patient's ribs from being injured.

[0034] On the basis of the above embodiments, in order to ensure that the chest area of ​​the patient's body is always directly below the pressing mechanism 102, the accuracy of the pressing position of the pressing mechanism 102 is ensured.

[0035] like Figure 1-Figure 4As shown, the driving mechanism 106 includes a slide groove 201 and a screw 202, a bracket 101 is provided on the base plate 103, the slide groove 201 is provided at the top of the bracket 101, the length direction of the slide groove 201 is in the same direction as the width direction of the base plate 103, the screw 202 is rotatably connected to the bracket 101, the screw 202 is arranged parallel to the slide groove 201, the screw 202 is connected to the power device 203, and both ends of the screw 202 are provided with external threads of opposite rotation directions. The left end of the screw 202 is threadedly connected to the left slider 204, and the left slider 204 is connected to the left push plate 104. The right end of the screw 202 is threadedly connected to the right slider 205, and the right slider 205 is connected to the right push plate 105.

[0036] When the driving mechanism 106 drives the left push plate 104 and the right push plate 105 to move, the power device 203 is controlled to move, and the power device 203 drives the lead screw 202 to rotate forward, and the left slider 204 and the right slider 205 rotate relative to the lead screw 202 under the restriction of the slide groove 201. Since the external threads at both ends of the lead screw 202 rotate in opposite directions, under the drive of the lead screw 202, the left slider 204 and the right slider 205 can always move synchronously toward each other, thereby ensuring that the left push plate 104 and the right push plate 105 can always move synchronously toward each other, so that when the left slider 204 and the right slider 205 move toward each other, the pressing mechanism 102 can always be located in the middle part of the left push plate 104 and the right push plate 105, thereby ensuring that the chest area of ​​the patient's body is always directly below the pressing mechanism 102, thereby ensuring the accuracy of the pressing position of the pressing mechanism 102.

[0037] As a preferred solution, Figure 3As shown, the left push plate 104 is provided with a left pressure sensor 301, and the left pressure sensor 301 is used to detect the real-time pressure value of the left push plate 104. The right push plate 105 is provided with a right pressure sensor 302, and the right pressure sensor 302 is used to detect the real-time pressure value of the right push plate 105. The power device 203 is electrically connected to a controller, and the controller is electrically connected to the left pressure sensor 301 and the right pressure sensor 302. When the real-time pressure value of the left push plate 104 is equal to the real-time pressure value of the right push plate 105, the controller controls the power device 203 to stop moving. By setting the left pressure sensor 301 and the right pressure sensor 302, when the driving mechanism 106 drives the left push plate 104 and the right push plate 105 to move toward each other, when the left push plate 104 or the right push plate 105 contacts the patient's body, the left push plate 104 or the right push plate 105 applies a thrust to the patient's body, and the patient's body applies a reverse pressure to the left push plate 104 or the right push plate 105. The left pressure sensor 301 is used to detect the real-time pressure value of the left push plate 104, and the right pressure sensor 302 is used to detect the real-time pressure value of the left push plate 104. 02 Detect the real-time pressure value of the right push plate 105. When the real-time pressure value of the left push plate 104 is equal to the real-time pressure value of the right push plate 105, it indicates that the left push plate 104 is in contact with the left side of the patient's body, and the right push plate 105 is in contact with the right side of the patient's body. The patient's body is restricted between the left push plate 104 and the right push plate 105. At this time, the controller controls the power device 203 to stop moving, thereby preventing the left push plate 104 and the right push plate 105 from pinching the patient and ensuring the safety of the device.

[0038] As a preferred solution, Figure 1As shown, a conveying mechanism 4 is provided on the base plate 103, and the patient's body is pressed on the conveying mechanism 4. The conveying mechanism 4 is used to drive the patient's body to move along the width direction of the base plate 103. The conveying mechanism 4 is electrically connected to the controller. When the real-time pressure value of the left push plate 104 is less than the real-time pressure value of the right push plate 105, the controller controls the conveying mechanism 4 to drive the patient's body to move to the left side of the base plate 103. When the real-time pressure value of the left push plate 104 is greater than the real-time pressure value of the right push plate 105, the controller controls the conveying mechanism 4 to drive the patient's body to move to the right side of the base plate 103. When the driving mechanism 106 drives the left push plate 104 and the right push plate 105 to move, and the left push plate 104 or the right push plate 105 pushes the patient's body to move, the left pressure sensor 301 detects the real-time pressure value of the left push plate 104, and the right pressure sensor 302 detects the real-time pressure value of the right push plate 105. When the real-time pressure value of the left push plate 104 is less than the real-time pressure value of the right push plate 105, it indicates that the patient's body is biased to the left, and the controller controls the transmission mechanism 4 to drive the patient's body to move to the right side of the bottom plate 103, thereby driving the patient's body to move to the right. When the real-time pressure value of the left push plate 104 is less than the real-time pressure value of the right push plate 105, it indicates that the patient's body is biased to the left. When the force value is greater than the real-time pressure value of the right push plate 105, it indicates that the patient's body is biased to the right. The controller controls the transmission mechanism 4 to drive the patient's body to move to the left side of the bottom plate 103. With the auxiliary drive of the transmission mechanism 4, it can prevent the patient's body from being twisted due to uneven force on both sides of the patient's body when the patient's body is pushed solely by the left push plate 104 or the right push plate 105. This prevents the patient's chest from being directly under the pressing mechanism 102 even when the left push plate 104 and the right push plate 105 are in contact with the patient's body, thereby ensuring the accuracy of the pressing position of the pressing mechanism 102.

[0039] As a preferred solution, Figure 1-Figure 4As shown, the pressing mechanism 102 includes a first cylinder body 601, a first piston 602 and a pressing block 603. The first cylinder body 601 is vertically arranged at the middle position of the left push plate 104 and the right push plate 105 on the bracket 101. The first piston 602 is slidably connected to the inner cavity of the first cylinder body 601. The pressing block 603 is connected to the bottom end of the first piston 602. The pressing block 603 is used to press the chest cavity of the patient's body. The inner cavity of the first cylinder body 601 is connected to a hydraulic control circuit, and the hydraulic control circuit is used to drive the first piston 602 to reciprocate in the vertical direction. The patient's position is adjusted by controlling the movement of the left push plate 104 and the right push plate 105. After the chest cavity of the patient's body is aligned with the bottom of the pressing block 603 of the pressing mechanism 102, the hydraulic control circuit is controlled to operate. The hydraulic control circuit drives the first piston 602 to reciprocate in the vertical direction. Since the first cylinder body 601 is vertically arranged in the middle position of the left push plate 104 and the right push plate 105 on the bracket 101, the first piston 602 reciprocates and drives the pressing block 603 to press up and down in the middle position of the left push plate 104 and the right push plate 105, thereby ensuring that the pressing block 603 can accurately press the patient's chest cavity.

[0040] As a preferred solution, Figure 1-Figure 4 As shown, the hydraulic control circuit includes a second cylinder body 901, a liquid supply device, a second piston 903 and a reciprocating motion mechanism 902, the inner cavity of the second cylinder body 901 is connected to the inner cavity of the first cylinder body 601 and the liquid supply device, the second piston 903 is slidably connected to the inner cavity of the second cylinder body 901, and the reciprocating motion mechanism 902 is connected to the second piston 903, and the reciprocating motion mechanism 902 is used to drive the second piston 903 to reciprocate axially along the second cylinder body 901. When driving the first piston 602 to reciprocate in the vertical direction, the reciprocating mechanism 902 is controlled to move, and the reciprocating mechanism 902 drives the second piston 903 to reciprocate in the second cylinder 901, thereby driving the amount of hydraulic oil in the inner cavity of the second cylinder 901 to change back and forth. Since the inner cavity of the second cylinder 901 is connected to the inner cavity of the first cylinder 601, the amount of hydraulic oil in the inner cavity of the first cylinder 601 will change back and forth, thereby driving the first piston 602 to reciprocate in the vertical direction, thereby driving the pressing block 603 to reciprocate in the vertical direction to perform reciprocating compression on the patient's chest cavity. During this process, the movement amplitude of the reciprocating mechanism 902 is constant, which can ensure that the amplitude of the reciprocating compression of the pressing block 603 in the vertical direction is constant, thereby ensuring the effect of cardiopulmonary resuscitation.

[0041] As a preferred solution, Figure 1-Figure 4As shown, the reciprocating movement amplitude of the second piston 903 driven by the reciprocating mechanism 902 in the vertical direction is adjustable. By adjusting the reciprocating movement amplitude of the second piston 903 driven by the reciprocating mechanism 902 in the vertical direction, the reciprocating movement amplitude of the pressing block 603 driven by the reciprocating mechanism 902 can be adjusted, so that the device can be used by patients with different body shapes.

[0042] As a preferred solution, Figure 3-Figure 6 As shown, the conveyor belt 7 of the conveyor mechanism 4 is a synchronous belt. Setting the conveyor belt 7 of the conveyor mechanism 4 as a synchronous belt can prevent the conveyor mechanism 4 from slipping when driving the patient's body to move, ensure the accuracy of the patient's body position, and further ensure the accuracy of the pressing position of the pressing block 603.

[0043] As a preferred solution, Figure 1 , Figure 3 and Figure 4 As shown, a rubber pad 8 is provided at the bottom of the pressing block 603. By arranging the rubber pad 8 at the bottom of the pressing block 603, it is possible to prevent the pressing block 603 from crushing the patient.

[0044] As a preferred solution, Figure 1 , Figure 3 and Figure 4 As shown, the left push plate 104 and the right push plate 105 have the same structure. The left push plate 104 and the right push plate 105 are arranged to have the same structure, which can ensure that the left push plate 104 or the right push plate 105 applies the same pressure to the patient's body when pushing the patient's body.

[0045] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
