Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a labor-saving auxiliary device for cardiopulmonary resuscitation. Background Art

[0002] Cardiopulmonary resuscitation is a commonly used first-aid measure at present, and is widely applied both in daily life and clinically. Cardiopulmonary resuscitation is to establish a temporary artificial circulation through methods such as cardiac compression and artificial respiration, ensure the blood supply of important organs in the body, and at the same time restore spontaneous heartbeat and respiration, so as to save the life of the patient.

[0003] When a patient suddenly faints, drowns or has a cardiac arrest, cardiac compression should be immediately performed so that the patient can quickly establish an effective artificial circulation and respiration and restore the blood supply to the whole body. When performing emergency cardiopulmonary resuscitation on a patient, attention should be paid to the compression site, compression frequency and compression depth, etc., to avoid incorrect compression methods causing sternal fractures or failing to achieve the compression effect.

[0004] At present, the operation of manual external chest compression consumes a huge amount of physical strength and requires several people to perform external chest compression alternately. The compression will stop during the alternation process, resulting in a decrease in the rescue success rate. Summary of the Invention

[0005] The purpose of the present invention is to provide a labor-saving auxiliary device for cardiopulmonary resuscitation, which is used to solve the problems in the prior art that the operation of manual external chest compression consumes a huge amount of physical strength, requires several people to perform external chest compression alternately, and the compression will stop during the alternation process, resulting in a decrease in the rescue success rate.

[0006] To achieve the above technical purpose, the technical solution adopted by the present invention is as follows: A labor-saving auxiliary device for cardiopulmonary resuscitation, comprising: A bracket spanning above the patient's chest; A boosting mechanism and a controller, the controller is signal-connected to the boosting mechanism for controlling the action of the boosting mechanism. The boosting mechanism is installed on the bracket, and a moving block is installed at the movable end of the boosting mechanism. The boosting mechanism is used to drive the moving block to move up and down; A pressing mechanism installed on the moving block, and a detection mechanism for detecting the up-and-down movement trend of the pressing mechanism is installed on the pressing mechanism. The detection mechanism is signal-connected to the controller; A pressing head, the pressing head is installed on the moving block and is located below the moving block for pressing the patient's chest; When the detection mechanism detects that the pressing mechanism has a downward movement trend, a first signal is sent to the controller, and the controller controls the boosting mechanism to drive the moving block to move downward, and presses the patient's chest through the pressing head; When the detection mechanism detects that the pressing mechanism has an upward movement tendency, it sends a second signal to the controller, and the controller controls the boosting mechanism to drive the moving block upward, thereby driving the pressing head away from the patient's chest.

[0007] Further defined, the pressing mechanism is vertically slidably mounted on the moving block, the detection mechanism is a pressure sensor, and the pressure sensor is located between the pressing mechanism and the slider; An elastic mechanism is provided between the pressing mechanism and the moving block.

[0008] With such a structural design, by vertically slidably mounting the pressing mechanism on the moving block, using the pressure sensor to detect the movement tendency exerted by the rescuer on the pressing mechanism, and cooperating with the elastic mechanism to support the pressing mechanism, the detection of the movement tendency of the pressing mechanism is realized; Specifically, when the rescuer pushes the pressing mechanism downward, it squeezes the pressure sensor, and the controller determines that the pressing mechanism has a downward movement tendency. Then, the controller controls the boosting mechanism to drive the pressing head downward to press the patient's chest; After one pressing is completed, when the rescuer's palm is lifted upward, under the action of the elastic mechanism, the pressing mechanism disengages from pressing the pressure sensor, and the controller determines that the pressing mechanism has an upward movement tendency. Then, the controller controls the boosting mechanism to drive the pressing head upward, thereby driving the pressing head away from the patient's chest to complete the reset.

[0009] Further defined, the pressing mechanism includes a connecting rod, and a supporting plate is installed at the top end of the connecting rod; The supporting plate is located above the boosting mechanism.

[0010] With such a structural design, through the arrangement of the connecting rod and the supporting plate, the distance between the user's palm and the boosting mechanism in the vertical direction is increased. On the basis of ensuring that the force application direction of the user's palm coincides with the movement direction of the pressing head, it avoids the boosting mechanism from obstructing the up and down movement of the rescuer's palm, and has strong practicability.

[0011] Further defined, an elastic band is installed at the upper end of the supporting plate.

[0012] With such a structural design, through the arrangement of the elastic band, the palm of the rescuer is restricted. It can not only reduce the risk of the rescuer's palm slipping, but also directly drive the supporting plate upward by the rescuer's palm through the elastic band, thereby accelerating the driving of the pressing mechanism to disengage from pressing the pressure sensor and improving the reaction speed of the device, and has strong practicability.

[0013] Further defined, the pressing mechanism includes an upper baffle, and the upper baffle is located above the moving block and is fixedly connected to the connecting rod; The pressure sensor is installed on the upper baffle and is located between the upper baffle and the slider.

[0014] With such a structural design, through the setting of the upper baffle, the pressure sensor is installed between the upper baffle and the slider, with a simple structure, convenient installation, and strong practicability.

[0015] Further defined, the pressing mechanism further includes a lower baffle; The lower baffle is located below the moving block; The connecting rod is vertically penetrated through the moving block and is fixedly connected to the lower baffle.

[0016] With such a structural design, through the penetration of the connecting rod through the moving block, the vertical sliding connection between the pressing mechanism and the moving block is completed, with a simple structure, convenient installation, and relatively strong practicability; Furthermore, the maximum upward movement position of the pressing mechanism relative to the moving block is defined by the lower baffle, making it more convenient to use.

[0017] Further defined, a push rod is installed on the moving block, and the lower end of the push rod passes through the pressing mechanism and is connected to the pressing head; The push rod includes a threaded rod and a threaded cylinder; The threaded rod and the threaded cylinder are screwed together; The threaded rod is fixedly connected to the moving block; The threaded cylinder is fixedly connected to the pressing head.

[0018] With such a structural design, through the push rod composed of the threaded rod and the threaded cylinder, the distance dimension between the moving block and the pressing head in the vertical direction is set to be adjustable, so as to be applicable to different patients, with relatively strong practicability.

[0019] Further defined, the assisting mechanism is a vertically arranged linear motor, and the linear motor includes a mover, and the mover is fixedly connected to the moving block.

[0020] With such a structural design, by using the vertically arranged linear motor as the assisting mechanism, the moving block is driven by the mover to move up and down to realize the pressing on the patient's chest, with a simple structure and relatively strong practicability.

[0021] Further defined, the stroke length of the mover is 5 cm - 6 cm.

[0022] With such a structural design, by limiting the stroke length of the mover to 5 cm - 6 cm, the pressing depth of the pressing head is 5 cm - 6 cm, which is matched with the pressing depth on the patient's chest during cardiopulmonary resuscitation, with a simple structure and relatively strong practicability.

[0023] Further defined, the bracket is in an X shape; The assisting mechanism is installed in the middle of the bracket; Each of the four free ends of the bracket is provided with a support leg, and a support pad is fixedly arranged at the outer end of the support leg.

[0024] With such a structural design, by setting the bracket in an X shape and fixedly arranging the support pad at the outer end of the support leg, the support pad can be used to support the knees of the rescuers, avoiding the problem of damage caused by the rescuers' knees directly touching the ground, and it has strong practicability.

[0025] The invention adopting the above technical solution has the following advantages: 1. By detecting the pressing action of the rescuer through the detection mechanism, the assisting mechanism is controlled to press the patient's chest through the pressing head, achieving the purpose of reducing the physical consumption of the rescuer and avoiding affecting the best rescue time for the emergency patient; 2. By vertically sliding and installing the pressing mechanism on the moving block, using the pressure sensor to detect the movement tendency exerted by the rescuer on the pressing mechanism, and cooperating with the elastic mechanism to support the pressing mechanism, the detection of the movement trend of the pressing mechanism is realized; 3. By the push rod composed of the threaded rod and the threaded barrel, the distance dimension between the moving block and the pressing head in the vertical direction is set to be adjustable, so as to be applicable to different patients, and it has strong practicability.

[0028] As Figures 1 to 8 shown, a labor-saving auxiliary device for cardiopulmonary resuscitation according to the present invention includes: A bracket 1 spanning above the patient's chest; An assisting mechanism 10 and a controller, the controller being in signal connection with the assisting mechanism 10 for controlling the action of the assisting mechanism 10. The assisting mechanism 10 is mounted on the bracket 1, and a moving block 2 is mounted at the movable end of the assisting mechanism 10. The assisting mechanism 10 is used to drive the moving block 2 to move up and down; A pressing mechanism 3 mounted on the moving block 2, and a detecting mechanism for detecting the up-and-down movement trend of the pressing mechanism 3 is mounted on the pressing mechanism 3. The detecting mechanism is in signal connection with the controller; A pressing head 34, the pressing head 34 being mounted on the moving block 2 and located below the moving block 2 for pressing on the patient's chest; When the detecting mechanism detects that the pressing mechanism 3 has a downward movement trend, a first signal is sent to the controller, and the controller controls the assisting mechanism 10 to drive the moving block 2 to move downward, and presses on the patient's chest through the pressing head 34; When the detecting mechanism detects that the pressing mechanism 3 has an upward movement trend, a second signal is sent to the controller, and the controller controls the assisting mechanism 10 to drive the moving block 2 to move upward, thereby driving the pressing head 34 to disengage from the patient's chest.

[0029] The pressing mechanism 3 is vertically slidably mounted on the moving block 2, and the detecting mechanism is a pressure sensor, and the pressure sensor is located between the pressing mechanism 3 and the slider 2; An elastic mechanism is provided between the pressing mechanism 3 and the moving block 2.

[0030] In fact, according to the actual situation, the pressing mechanism 3 can also be fixedly installed on the moving block 2, and then the acceleration sensor is used as the detection mechanism to detect the up-and-down movement trend of the pressing mechanism 3. In this embodiment, the pressing mechanism 3 is vertically slidably installed on the moving block 2, and the pressure sensor is used to detect the movement tendency applied by the rescuer to the pressing mechanism 3, and cooperate with the elastic mechanism to support the pressing mechanism 3 to realize the detection of the movement trend of the pressing mechanism 3; Specifically, when the rescuer pushes the pressing mechanism 3 downward, it squeezes the pressure sensor, and the controller determines that the pressing mechanism 3 has a downward movement trend. Then, the controller controls the assisting mechanism 10 to drive the pressing head 34 downward to press the patient's chest; After one pressing is completed, when the rescuer's palm is lifted upward, the pressing mechanism 3 disengages from pressing the pressure sensor under the action of the elastic mechanism. The controller determines that the pressing mechanism 3 has an upward movement trend, and then the controller controls the assisting mechanism to drive the pressing head 34 upward, thereby driving the pressing head 34 away from the patient's chest to complete the reset.

[0031] The elastic mechanism can be a compression spring or a rubber pad.

[0032] The pressing mechanism 3 includes a connecting rod 33, and a supporting plate 35 is installed at the top of the connecting rod 33; The supporting plate 35 is located above the assisting mechanism 10.

[0033] In fact, according to the actual situation, the pressing mechanism 3 can also be directly installed on the side of the moving block 2 to avoid the obstruction of the assisting mechanism 10 to the rescuer's palm. In this embodiment, through the arrangement of the connecting rod 33 and the supporting plate 35, the distance between the user's palm and the assisting mechanism 10 in the vertical direction is increased. On the basis of ensuring that the force application direction of the user's palm coincides with the movement direction of the pressing head 34, the assisting mechanism 10 is prevented from obstructing the up-and-down movement of the rescuer's palm, and the practicability is strong.

[0034] An elastic band 350 is installed at the upper end of the supporting plate 35.

[0035] Through the arrangement of the elastic band 350, the rescuer's palm is restricted, which can not only reduce the risk of the rescuer's palm slipping, but also directly drive the supporting plate 35 to move upward by the rescuer's palm through the elastic band 350, thereby accelerating the driving of the pressing mechanism 3 to disengage from the extrusion of the pressure sensor, improving the reaction speed of the device, and having strong practicability.

[0036] The pressing mechanism 3 includes an upper baffle 31, and the upper baffle 31 is located above the moving block 2 and is fixedly connected to the connecting rod 33; The pressure sensor is installed on the upper baffle 31 and is located between the upper baffle 31 and the slider 2.

[0037] Actually, according to the actual situation, a support rod can also be fixedly arranged on the slider 2, and the pressure sensor can be installed on the lower end surface of the supporting plate 35. In this embodiment, through the setting of the upper baffle 31, the pressure sensor is installed between the upper baffle 31 and the slider 2, with a simple structure, convenient installation, and strong practicability.

[0038] The pressing mechanism 3 further includes a lower baffle 32; The lower baffle 32 is located below the moving block 2; The connecting rod 33 is vertically arranged through the moving block 2 and is fixedly connected to the lower baffle 32.

[0039] Actually, according to the actual situation, a slide rail with a limiting mechanism can also be installed between the pressing mechanism 3 and the moving block 2 to achieve sliding connection and limiting with the slide rail with a limiting mechanism. In this embodiment, through the arrangement of the connecting rod 33 passing through the moving block 2, the vertical sliding connection between the pressing mechanism 3 and the moving block 2 is completed, with a simple structure, convenient installation, and relatively strong practicability; Furthermore, the lower baffle 33 completes the limitation of the maximum upward movement position of the pressing mechanism 3 relative to the moving block 2, making it more convenient to use.

[0040] A push rod is installed on the moving block 2, and the lower end of the push rod passes through the pressing mechanism 3 and is connected to the pressing head 34; The push rod includes a threaded rod 341 and a threaded cylinder 342; The threaded rod 341 and the threaded cylinder 342 are screwed together; The threaded rod 341 is fixedly connected to the moving block 2; The threaded cylinder 342 is fixedly connected to the pressing head 34.

[0041] Actually, according to the actual situation, the height dimension of the sliding block 2 in the vertical direction can also be lengthened, and the pressing head 34 can be directly installed on the sliding block 2. In this embodiment, through the push rod composed of the threaded rod 341 and the threaded cylinder 342, the distance dimension between the moving block 2 and the pressing head 34 in the vertical direction is set to be adjustable to suit different patients, with relatively strong practicability.

[0042] The boosting mechanism 10 is a vertically arranged linear motor, and the linear motor includes a mover 20, and the mover 20 is fixedly connected to the moving block 2.

[0043] Actually, according to the actual situation, a rotary motor can also be selected to drive a lead screw to rotate laterally, and then the moving block 2 sliding vertically is screwed on the lead screw as the boosting mechanism 10 to drive the moving block 2 to move up and down. In this embodiment, by using the vertically arranged linear motor as the boosting mechanism 10, the mover 20 drives the moving block 2 to move up and down to achieve the pressing on the patient's chest, with a simple structure and relatively strong practicability.

[0044] The stroke length of the mover 20 is 5 cm - 6 cm.

[0045] In fact, according to the actual situation, the stroke length of the mover 20 can also be set to other values, and a limit mechanism can be additionally provided. In this embodiment, by limiting the stroke length of the mover 20 to 5 cm - 6 cm, the pressing depth of the pressing head 34 is 5 cm - 6 cm, which matches the pressing depth of the patient's chest during cardiopulmonary resuscitation. The structure is simple and the practicability is strong.

[0046] The bracket 1 is in an X shape; The boosting mechanism 10 is installed in the middle of the bracket 1; Support legs 11 are provided at the four free ends of the bracket 1, and support pads 12 are fixedly provided at the outer ends of the support legs 11.

[0047] In fact, according to the actual situation, the bracket 1 can also be set to an H shape. In this embodiment, by setting the bracket 1 to an X shape and fixedly providing the support pads 12 at the outer ends of the support legs 11, the support pads 12 can be used to support the knees of the rescuer, avoiding the problem of damage caused by the direct placement of the rescuer's knees on the ground, and the practicability is strong.

[0048] In this embodiment, the bracket 1 is spanned above the patient's chest, so that the pressing head 34 is located directly above the patient's chest. The rescuer then kneels on one side of the patient and places the knees on the support pads 12; Then rotate the pressing head 34 to drive the threaded cylinder 342 to rotate relative to the threaded rod 341 until the pressing head 34 abuts against the patient's chest; The palm of the rescuer passes through the elastic band 350 and is placed on the supporting plate 35, and then the supporting plate 35 is pressed downward, so that the upper baffle 31 overcomes the prestress of the elastic mechanism, forming an extrusion on the pressure sensor. The pressure sensor sends a first signal to the controller, and then the controller determines that the pressing mechanism 3 has a downward movement trend. Furthermore, the controller controls the boosting mechanism 10 to drive the pressing head 34 to move downward to press the patient's chest; After one pressing is completed, when the palm of the rescuer is lifted upward, the pressing mechanism 3 is separated from the pressing of the pressure sensor under the action of the elastic band 350 and the elastic mechanism. The pressure sensor sends a second signal to the controller, and then the controller determines that the pressing mechanism 3 has an upward movement trend. Furthermore, the controller controls the boosting mechanism to drive the pressing head 34 to move upward, thereby driving the pressing head 34 to separate from the patient's chest and completing the reset; Repeat the above actions to complete the cardiopulmonary resuscitation of the patient.
