Description

Technical Field

[0001] This application relates to the field of emergency medical equipment testing equipment technology, and in particular to a cardiopulmonary resuscitation machine performance testing device. Background Technology

[0002] A cardiopulmonary resuscitation (CPR) machine is an automated medical device that can replace or assist rescuers in performing standard CPR procedures when a patient experiences cardiac arrest.

[0003] In related technologies, cardiopulmonary resuscitation (CPR) machines have hooks on both sides for connecting straps. After the CPR machine is manufactured, its compression performance needs to be tested to ensure it meets standard requirements. During the compression performance test, limit blocks on both sides of the CPR machine testing device press against the hooks on both sides of the CPR machine, thus pressing the CPR machine against the testing device for performance testing.

[0004] However, the two limiting blocks of this type of cardiopulmonary resuscitation machine testing device are in fixed positions, which can only be used for cardiopulmonary resuscitation machines of one size and cannot be used to test cardiopulmonary resuscitation machines of other sizes. Utility Model Content

[0005] This application provides a cardiopulmonary resuscitation (CPR) machine performance verification device for verifying the performance of a CPR machine.

[0006] This application provides a cardiopulmonary resuscitation machine performance verification device, including:

[0007] Frame;

[0008] Guide components are installed within the frame;

[0009] An abutment assembly that mates with the guide member;

[0010] An elastic element is disposed within the frame, and the elastic element abuts against the abutting assembly;

[0011] Detection sensors are respectively connected to the frame and the abutment assembly;

[0012] A limiting and fixing assembly is hinged to the frame, which can fix cardiopulmonary resuscitation machines of different sizes to the frame;

[0013] The movable part of the cardiopulmonary resuscitation machine abuts against the abutting assembly. The abutting assembly reciprocates along the guide under the action of the cardiopulmonary resuscitation machine and the elastic member. The detection sensor monitors the motion state of the abutting assembly to reflect the performance of the cardiopulmonary resuscitation machine.

[0014] In one feasible implementation, the guide is configured as a guide rod vertically disposed within the frame, and at least two guide rods are provided;

[0015] At least two of the guide rods are spaced apart, and the abutment assembly slides with all of the guide rods.

[0016] In one feasible implementation, the abutting component includes a first abutting portion and a second abutting portion, the first abutting portion being selectively fixed to the second abutting portion, and the elastic member being able to penetrate the second abutting portion and its end abutting against the first abutting portion.

[0017] In one feasible implementation, two limiting and fixing components are provided, each hinged to the frame, and both can swing selectively to jointly limit and fix the cardiopulmonary resuscitation machine to the frame.

[0018] In one feasible implementation, the limiting and fixing assembly includes a vertical bar and a horizontal bar, with the two ends of the horizontal bar connected to the two vertical bars respectively, and the two vertical bars respectively hinged to the frame.

[0019] In one feasible implementation, the limiting and fixing assembly further includes a knob fixing member, with the two ends of the horizontal bar respectively sleeved on the corresponding vertical bar, and the horizontal bar being fixedly connected to the vertical bar through the knob fixing member.

[0020] In one feasible implementation, the cardiopulmonary resuscitation machine performance verification device further includes:

[0021] The elastic member is coupled with the lifting platform mounted on the guide member, with one end abutting against the lifting platform and the other end abutting against the abutting component;

[0022] The lifting seat is installed inside the frame, and one end of the guide rod is connected to the frame and the other end is connected to the lifting seat;

[0023] The lifting drive assembly, which is mounted on the lifting seat, is connected to the lifting platform. The lifting drive assembly is used to drive the lifting platform to move along the guide member, thereby changing the distance between the lifting platform and the abutment assembly.

[0024] In one feasible implementation, the detection sensor is configured as a pull-wire sensor, with one end connected to the lifting platform and the other end connected to the abutment assembly.

[0025] In one feasible implementation, the frame is configured as a box, the top of which has a through hole for the moving part of the cardiopulmonary resuscitation machine to pass through.

[0026] In one feasible implementation, the side of the housing is provided with a handle.

[0027] This application provides a cardiopulmonary resuscitation (CPR) machine performance calibration device, including a frame, a guide member, an abutment component, an elastic member, a limiting and fixing component, and a detection sensor. The guide member is disposed within the frame, and the abutment component is connected to and cooperates with the guide member. The elastic member is also disposed within the frame and abuts against the abutment component, providing continuous elastic force to the abutment component. The detection sensor is connected to the frame and the abutment component respectively to detect changes in the distance between the abutment component and the frame. The limiting and fixing component is hinged to the frame, enabling CPR machines of different sizes to be fixed to the frame, thereby allowing the CPR machine performance calibration device to perform performance calibration on CPR machines of various sizes and specifications.

[0028] During the performance calibration of a cardiopulmonary resuscitation (CPR) machine, a limiting and fixing component secures the CPR machine to the frame. The moving part of the CPR machine abuts against the abutment component. During the reciprocating motion of the moving part, the abutment component simultaneously reciprocates under the action of its moving end and the elastic element. Because the distance between the abutment component and the frame changes during this reciprocating motion, a detection sensor monitors this change in distance. This change in distance between the abutment component and the frame reflects the performance of the CPR machine, thus enabling the calibration of its performance. Attached Figure Description

[0044] Cardiopulmonary resuscitation (CPR) machines are automated medical devices that can replace or assist rescuers in performing standard cardiopulmonary resuscitation procedures when a patient experiences cardiac arrest.

[0045] In related technologies, cardiopulmonary resuscitation (CPR) machines have hooks on both sides for connecting straps. After the CPR machine is manufactured, its compression performance needs to be tested to ensure it meets standard requirements. During the compression performance test, limit blocks on both sides of the CPR machine testing device press against the hooks on both sides of the CPR machine, thus pressing the CPR machine against the testing device for performance testing.

[0046] However, the two limiting blocks of this type of cardiopulmonary resuscitation machine testing device are in fixed positions, which can only be used for cardiopulmonary resuscitation machines of one size and cannot be used to test cardiopulmonary resuscitation machines of other sizes.

[0047] Therefore, this application provides a cardiopulmonary resuscitation machine performance verification device. The solution provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0048] Figure 1 This is a schematic diagram of the overall structure of a cardiopulmonary resuscitation machine performance verification device provided in one embodiment of this application; Figure 2 yes Figure 1 A first internal schematic diagram of the cardiopulmonary resuscitation machine performance verification device. Figure 3 yes Figure 1 A second internal schematic diagram of the cardiopulmonary resuscitation machine performance verification device. Figure 4 yes Figure 1 A schematic diagram of the cardiopulmonary resuscitation machine performance verification device after removing the frame 100.

[0049] Reference Figures 1 to 4As shown, this application embodiment provides a cardiopulmonary resuscitation machine performance verification device, including a frame 100, a guide 200, an abutment component 300, an elastic element 400, a limiting and fixing component 600, and a detection sensor 500. Exemplarily, the frame 100 can be a cuboid frame structure or a box structure. The guide 200 is disposed within the frame 100, and the abutment component 300 is connected to the guide 200. The elastic element 400 is also disposed within the frame 100, with one end abutting against the surface of the abutment component 300 and the other end connected to the frame 100. For example, the guide 200 can be horizontally or vertically disposed within the frame. Exemplarily, the guide 200 is vertically disposed on the lower inner surface of the frame 100, and one end of the elastic element 400 abuts against the inner surface of the frame 100, while the other end abuts against the surface of the abutment component 300. The elastic element 400 provides continuous elastic force to the abutment component 300. The detection sensor 500 is connected to the frame 100 and the abutment component 300 respectively, and is used to detect changes in the distance between the abutment component 300 and the frame 100. The limiting and fixing component 600 is hinged to the frame 100. This limiting and fixing component 600 can fix cardiopulmonary resuscitation (CPR) machines of different sizes onto the frame 100, thereby enabling the CPR machine performance calibration device to perform performance calibration on CPR machines of various specifications and sizes. Specifically, different sizes of CPR machines refer to CPR machines of different specifications, with different spacing between the two hooks on both sides of different specifications. The limiting and fixing component 600 can adapt to the different hook spacing positions, thereby fixing CPR machines of different specifications onto the frame 100.

[0050] During the performance verification of the cardiopulmonary resuscitation (CPR) machine, the limiting and fixing component 600 limits and fixes the CPR machine to the frame 100. The movable part of the CPR machine abuts against the abutment component 300. During the reciprocating motion of the movable part, the abutment component 300 reciprocates simultaneously under the action of the movable end and the elastic element 400. Because the distance between the abutment component 300 and the frame 100 changes during the reciprocating motion, the detection sensor 500 monitors the change in distance between the abutment component 300 and the frame 100. The change in distance between the abutment component 300 and the frame 100 can be used to reflect the performance of the CPR machine, thus achieving the verification of the CPR machine's performance. It should be noted that the movable part of the CPR machine refers to the compression head of the CPR machine, used to perform chest compressions on the human body.

[0051] For example, the elastic element 400 can be a compression spring. The guide element 200 can be configured as a guide rod, and at least two guide rods are provided, all of which are vertically arranged within the frame 100 and spaced apart. The abutment component 300 is provided with a through hole that mates with the guide rod, and the abutment component 300 is connected to all the guide rods through the through hole. The abutment component 300 can move up and down under the guidance and limiting action of the guide rods. The abutment component 300 can be an abutment plate, the lower surface of which abuts against the upper end of the elastic element 400.

[0052] Figure 5 yes Figure 1 A first schematic diagram of some components of the cardiopulmonary resuscitation machine performance verification device after assembly; Figure 6 yes Figure 1 The second schematic diagram shows the assembled components of the cardiopulmonary resuscitation machine performance verification device.

[0053] Reference Figure 5 and Figure 6 As shown, in some examples, the abutment component 300 includes a first abutment portion 310 and a second abutment portion 320. The top surface of the second abutment portion 320 is provided with a circular through hole. The first abutment portion 310 is configured as a cylinder, and the diameter of its horizontal cross-section is greater than or equal to the size of the circular through hole. The first abutment portion 310 is connected to the second abutment portion 320 by bolts. The first abutment portion 310 and the second abutment portion 320 enclose a placement space for the elastic member 400. The size of the elastic member 400 is smaller than the diameter of the circular through hole, and one end of it is located in the placement space and abuts against the first abutment portion 310, that is, the elastic member 400 can pass through the second abutment portion 320 and its end abuts against the first abutment portion 310. The detection sensor 500 is connected to the second abutment portion 320 and the frame 100 respectively.

[0054] Because different specifications of CPR machines have different performance characteristics, such as varying compression force and compression speed, it is necessary to select a corresponding elastic element 400 for performance testing. When replacing the elastic element 400, the first abutment 310 is removed from the second abutment 320, and then the original elastic element 400 is removed from the circular through-hole of the second elastic element 400, facilitating the replacement with a corresponding elastic element 400. Furthermore, when replacing the spring, there is no need to adjust the position of the second abutment 320, thus maintaining the distance between the second abutment 320 and the frame 100, and therefore not affecting the operation of the detection sensor 500. Therefore, there is no need to calibrate the detection sensor 500 after replacing the elastic element 400, improving the efficiency of CPR machine performance verification while reducing verification errors and increasing verification accuracy.

[0055] Continue to refer to Figures 1 to 4As shown, in some examples, two limiting and fixing components 600 are provided. Each of the two limiting and fixing components 600 is hinged to the top of the frame 100, and they are arranged opposite each other, allowing for selective swinging. When the cardiopulmonary resuscitation (CPR) machine is fixed to the frame 100, the two limiting and fixing components 600 swing upwards from the sides, pressing against the sides of the CPR machine, thereby jointly limiting and fixing the CPR machine to the frame 100. At this time, the movable part of the CPR machine passes through the upper part of the frame 100 and abuts against the abutment component 300 inside it. Exemplarily, the limiting and fixing component 600 includes a vertical rod 620 and a horizontal rod 610. The two ends of the horizontal rod 610 are connected to the two vertical rods 620, and the two vertical rods 620 are hinged to the frame 100.

[0056] like Figure 4 As shown, the limiting and fixing assembly 600 also includes a knob fixing member 630. The two ends of the horizontal bar 610 are respectively sleeved on the corresponding vertical bars 620, and the horizontal bar 610 is fixedly connected to the vertical bars 620 via the knob fixing member 630. By adjusting the position of the knob fixing member 630, the fixed connection position between the vertical bars 620 and the horizontal bar 610 can be adjusted, i.e., the distance between the horizontal bar 610 and the surface of the frame 100 can be adjusted, thereby accommodating the thickness of the side walls of different specifications of CPR machines and ensuring that CPR machines of various specifications can be securely fixed on the frame 100. For example, the vertical bar 620 can be configured as a screw, and the knob fixing member 630 can be a nut. The horizontal bar 610 and the vertical bar 620 are fixedly connected by setting a knob fixing member 630 at the top and bottom of the horizontal bar 610, respectively. When it is necessary to adjust the connection position between the horizontal bar 610 and the vertical bar 620, the positions of the two knob fixing members 630 at the top and bottom of the horizontal bar 610 can be adjusted respectively.

[0057] like Figures 3 to 6 As shown, in some examples, the cardiopulmonary resuscitation machine performance verification device further includes a lifting platform 700, a lifting seat 800, and a lifting drive assembly 900. The lifting seat 800 is fixedly mounted on the bottom surface inside the frame 100. One end of the guide member 200 is fixedly mounted on the lifting seat 800, and the other end is fixedly connected to the upper end of the frame 100. The lifting platform 700 has a through hole that mates with the guide member 200, and is positioned below the abutment assembly 300. One end of the elastic member 400 abuts against the lifting platform 700, and the other end abuts against the abutment assembly 300.

[0058] A lifting drive assembly 900 is mounted on the lifting base 800 and connected to the lifting platform 700. The lifting drive assembly 900 drives the lifting platform 700 to move along the guide member 200, thereby changing the distance between the lifting platform 700 and the abutment component 300. This ensures that the upper surface of the abutment component 300 at the upper end of the elastic member 400 can abut against the moving part of the cardiopulmonary resuscitation machine. For example, the lifting drive assembly 900 can be a screw-nut drive assembly, with the drive nut mounted on the lifting base 800 and the drive screw connected to it. One end of the drive screw has a drive handle, and the other end abuts against the lower surface of the lifting platform 700. When the drive handle is rotated, the drive screw rises and falls under the action of the drive nut, thereby driving the lifting platform 700 to rise and fall.

[0059] For example, the detection sensor 500 can be configured as a pull-wire sensor, with one end of the pull-wire sensor connected to the lifting platform 700 and the other end connected to the abutment component 300.

[0060] Reference Figures 1 to 3 As shown, in some examples, the frame 100 is configured as a box with a through-hole at the top for the movable part of the cardiopulmonary resuscitation (CPR) machine to pass through. A limiting and fixing assembly 600 is hinged to the top of the box. The limiting and fixing assembly 600 secures the CPR machine to the top of the box, and the movable part of the CPR machine, passing through the through-hole at the top of the box, abuts against an abutment assembly 300. For ease of movement, in some examples, a handle is provided on the side of the box.

[0061] It is readily understood that, based on the several embodiments provided in this application, those skilled in the art can combine, split, or reorganize the embodiments of this application to obtain other embodiments, none of which exceed the protection scope of this application.

It should be understood that the above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application.
