Description

Technical Field

[0001] This application relates to the field of emergency medical equipment technology, and in particular to a self-locking connection component and a cardiopulmonary resuscitation device. Background Technology

[0002] A cardiopulmonary resuscitation (CPR) machine (also known as a chest compression machine) is a medical device used for cardiopulmonary resuscitation, typically in emergency medical situations and rescue operations. A CPR machine allows for continuous, accurate, and stable chest compressions.

[0003] In related technologies, when using a cardiopulmonary resuscitation (CPR) machine to perform chest compressions on a patient, the operator wraps a bandage around the patient's back and connects the bandage buckles at both ends to the compression unit of the CPR machine via open hooks. The compression unit is then fixed to the patient's chest, enabling chest compressions to be performed.

[0004] However, since the bandage and the compression unit are separate structures, during the dynamic compression of the patient's chest cavity by the compression unit, the bandage buckle may fall off the open hook due to the vibration of the compression unit, causing the bandage to disconnect from the compression unit, affecting the continuity of compression and delaying the patient's rescue. Summary of the Invention

[0006] In a first aspect, embodiments of this application provide a self-locking connection component, including: Connect the hook; It can be used with the bandage shaft set in the connecting hook; The bandage shaft can be selectively placed in the connecting hook. When the bandage shaft is fitted into the connecting hook, the bandage shaft can only be dislodged from the connecting hook at a specific angle.

[0007] In one feasible implementation, a stepped platform is provided at each end of the bandage shaft; The opening of the connecting hook is larger than the maximum straight-line distance between the step platform and the side of the bandage shaft, and smaller than the diameter of the bandage shaft.

[0008] In one feasible implementation, two stepped platforms with opposite positions are respectively provided at both ends of the bandage shaft; The size of the opening of the connecting hook is greater than the straight-line distance between two opposing step platforms and less than the diameter of the bandage shaft.

[0009] In one feasible implementation, the self-locking connection component further includes a limiting component; The limiting component is disposed on the connecting hook, and the bandage shaft can enter the connecting hook through the limiting component; when the bandage shaft is located in the connecting hook, the limiting component can contact the step platform and restrict the free rotation of the bandage shaft.

[0010] In one feasible implementation, the limiting component is configured as a spring plunger.

[0011] In one possible implementation, the bandage shaft is provided with a limiting step, which is used to prevent the limiting shaft from sliding out axially from the connecting hook.

[0012] Secondly, embodiments of this application also provide a cardiopulmonary resuscitation device, comprising: The main unit used for chest compressions on patients; A bandage used to secure the compression device to the patient's chest cavity; Both ends of the bandage are connected to the pressing host via the self-locking connection assembly.

[0013] In one feasible implementation, the end of the bandage is fixedly connected to the bandage shaft, the connecting hook is fixedly mounted on the pressing host, and the bandage shaft selectively engages with the connecting hook.

[0014] In one feasible implementation, a stepped platform is provided at each end of the bandage shaft; The opening of the connecting hook is larger than the maximum straight-line distance between the step platform and the side of the bandage shaft, and smaller than the diameter of the bandage shaft.

[0015] In one feasible implementation, two stepped platforms with opposite positions are respectively provided at both ends of the bandage shaft; The size of the opening of the connecting hook is greater than the straight-line distance between two opposing step platforms and less than the diameter of the bandage shaft.

[0016] In a first aspect, embodiments of this application provide a self-locking connection assembly, including a connecting hook and a bandage shaft.

[0026] A cardiopulmonary resuscitation (CPR) machine is a medical device used for cardiopulmonary resuscitation, typically in emergency medical situations and rescue operations. A CPR machine allows for continuous, accurate, and stable chest compressions.

[0027] In related technologies, when using a cardiopulmonary resuscitation (CPR) machine to perform chest compressions on a patient, the operator wraps a bandage around the patient's back and connects the bandage buckles at both ends to the compression unit of the CPR machine via open hooks. The compression unit is then fixed to the patient's chest, enabling chest compressions to be performed.

[0028] However, since the bandage and the compression unit are separate structures, during the dynamic compression of the patient's chest cavity by the compression unit, the bandage buckle may fall off the open hook due to the vibration of the compression unit, causing the bandage to disconnect from the compression unit, affecting the continuity of compression and delaying the patient's rescue.

[0029] To address the aforementioned problems, this application provides a self-locking connection component and a cardiopulmonary resuscitation device. The solutions provided by this application will be described in detail below with reference to the accompanying drawings.

[0030] Figure 1 This is a schematic diagram of the overall structure of a self-locking connection component provided in an embodiment of this application.

[0031] like Figure 1 As shown, this application embodiment provides a self-locking connection assembly, including a connecting hook 110 and a bandage shaft 120. The connecting hook 110 can be mounted on a massage unit. The bandage shaft 120 is used to connect with a bandage and can be selectively engaged in the connecting hook 110. When the bandage shaft 120 is engaged in the connecting hook 110, the bandage shaft 120 can only disengage from the connecting hook 110 at a specific angle. When it is necessary to connect the bandage to the massage unit, by utilizing the characteristics that the bandage shaft 120 and the connecting hook 110 can quickly engage and connect, and that the bandage shaft 120 can only disengage from the connecting hook 110 at a specific angle, the bandage can be quickly connected to the massage unit using the bandage shaft 120 and the connecting hook 110, and is not easily loosened, thus solving the problems of complex operation and unstable connection of the bandage to the massage unit in the prior art.

[0032] like Figure 1 As shown, exemplarily, the self-locking connection assembly includes two connecting hooks 110 and a bandage shaft 120. The two connecting hooks 110 are spaced apart and fixedly mounted on the pressing main unit. The two ends of the bandage shaft 120 are respectively engaged and connected to the corresponding connecting hooks 110.

[0033] Figure 2 yes Figure 1 A schematic diagram of the structure of the connecting hook 110.

[0034] like Figure 2 As shown, the connecting hook 110 has a mating space 112, and an opening 111 is provided on the upper side of the mating space 112, through which the end of the bandage shaft 120 can enter the mating space 112.

[0035] In some examples, each end of the bandage shaft 120 has a stepped platform 121 parallel to its axis. The opening 111 of the connecting hook 110 is larger than the maximum straight-line distance between the stepped platform 121 and the side of the bandage shaft 120, but smaller than the diameter of the bandage shaft 120. Because the opening 111 of the connecting hook 110 is larger than the maximum straight-line distance between the stepped platform 121 and the side of the bandage shaft 120, the end of the bandage shaft 120 can move through the opening 111 of the connecting hook 110 into the mating space 112 of the bandage shaft 120. Furthermore, because the opening 111 of the connecting hook 110 is smaller than the diameter of the bandage shaft 120, after the end of the bandage shaft 120 enters the mating space 112, rotating the bandage shaft 120 to adjust the angle prevents the end of the bandage shaft 120 from moving out of the opening 111 of the connecting hook 110.

[0036] Figure 3 yes Figure 1 A schematic diagram of the structure of the bandage shaft 120. Figure 4 This is a schematic diagram of the first state during the connection process between the bandage shaft 120 and the connecting hook 110; Figure 5 This is a schematic diagram of the second state during the connection process between the bandage shaft 120 and the connecting hook 110; Figure 6 This is a schematic diagram of the third state of the connection process between the bandage shaft 120 and the connecting hook 110.

[0037] In other examples, such as Figure 3 As shown, two stepped platforms 121 are respectively provided at both ends of the bandage shaft 120, which are opposite to each other and parallel to the axis of the bandage shaft 120. The size of the opening 111 of the connecting hook 110 is larger than the straight-line distance between the two opposite stepped platforms 121, and smaller than the diameter of the bandage shaft 120, that is... Figure 4 In this case, 'a' is greater than 'b' and 'a' is less than 'c'. Similarly, since the size of the opening 111 of the connecting hook 110 is greater than the straight-line distance between the two opposing step platforms 121, the end of the bandage shaft 120 can enter the mating space 112 through the opening 111. Furthermore, because the size of the opening 111 of the connecting hook 110 is smaller than the diameter of the bandage shaft 120, when the bandage shaft 120 rotates a certain angle, the end of the bandage shaft 120 cannot be moved out of the opening 111 of the connecting hook 110 unless it rotates to the angle at which it enters the mating space 112.

[0038] Understandably, in emergency situations, the bandage shaft 120 can be adjusted to the correct angle (e.g., ...). Figure 5 (As shown) and quickly insert it into the mating space 112 from the opening 111, then rotate the bandage shaft 120 90 degrees (as shown). Figure 6As shown in the diagram, the bandage can be quickly connected to the main unit. In this state, due to size limitations, the bandage shaft 120 cannot exit the mating space 112 from the opening 111. To allow the bandage shaft 120 to exit the mating space 112 from the opening 111, the bandage shaft 120 must be rotated 90 degrees again before it can exit. However, the vibration of the main unit during operation can only bring a small amount of reciprocating displacement to the bandage shaft 120, which cannot accurately adjust the bandage shaft 120 to rotate 90 degrees, thus preventing the bandage shaft 120 from coming out of the connecting hook 110, ensuring the stability of the connection between the bandage and the main unit.

[0039] In some examples, the opening 111 of the connecting hook 110 faces vertically upwards. When the bandage is connected to the compression unit, the compression unit is pressed against the patient's chest by the elasticity of the bandage, and the bandage shaft 120 presses against the connecting hook 110. Due to the multiple constraints of the bandage elasticity, the weight of the bandage shaft 120, and the size of the end of the bandage shaft 120, the bandage shaft 120 will not disengage from the vertically upward opening 111 of the connecting hook 110.

[0040] In these examples, the opening 111 of the connecting hook 110 faces upward. When engaging the bandage shaft 120 with the connecting hook 110, first adjust the angle of the bandage shaft 120 so that the position of its smallest end dimension matches the opening 111, such as... Figure 4 As shown; then the stepped platform 121 of the bandage shaft 120 enters the mating space 112 through the opening 111, as... Figure 5 As shown; finally, rotate the bandage shaft 120 to change its angle so that it cannot move out of the opening 111, as shown. Figure 6 As shown.

[0041] Continue to refer to Figure 1 and Figure 2 As shown, in some other examples, the self-locking connection assembly also includes a limiting component 130, which is disposed at the opening 111 of the connecting hook 110, allowing the bandage shaft 120 to pass through the limiting component 130 into the connecting hook 110. When the bandage shaft 120 is in the connecting hook 110, the limiting component 130 can contact the step platform 121 and restrict the free rotation of the bandage shaft 120, thereby preventing the angle of the bandage shaft 120 from changing and ensuring that the bandage shaft 120 cannot be removed from the connecting hook 110. See details for further information. Figure 1 and Figure 6 As shown, when the bandage shaft 120 enters the mating space 112 and rotates, the limiting component 130 can block one side of the step platform 121, preventing the bandage shaft 120 from rotating further, thereby preventing the smaller end of its side from aligning with the opening 111 and preventing the bandage shaft 120 from moving out of the opening 111.

[0042] For example, the limiting component 130 may be an elastic limiting member or a spring plunger, which can prevent the bandage shaft 120 from entering the mating space 112 from the opening 111, and also prevent the bandage shaft 120 from rotating.

[0043] like Figure 4 and Figure 5 As shown, when the bandage shaft 120 enters through the opening 111, the bandage shaft 120 will press against the limiting component 130, causing it to retract. Figure 6 As shown, when the bandage shaft 120 enters the mating space 112 and the angle is adjusted, the end of the limiting component 130 protrudes again from the surface of the connecting hook 110 under the action of the elastic component and contacts the stepped platform 121 of the bandage shaft 120, thus restricting the rotation of the bandage shaft 120.

[0044] Continue to refer to Figure 1 As shown, in some examples, both ends of the bandage shaft 120 are provided with limiting steps 122. The limiting steps 122 can abut against the side of the connecting hook 110, thereby preventing the limiting shaft from sliding out of the connecting hook 110 axially and ensuring a stable connection between the bandage shaft 120 and the connecting hook 110.

[0045] Figure 7 This is a schematic diagram of the cardiopulmonary resuscitation device provided in one embodiment of this application.

[0046] like Figure 7 As shown, in a second aspect, this application also provides a cardiopulmonary resuscitation (CPR) device, including a compression unit 200, a bandage (not shown), and a self-locking connection assembly 100. The compression unit 200 is used to compress the patient's chest cavity, and the bandage is used to fix the compression unit 200 to the patient's chest cavity. Both ends of the bandage are connected to the compression unit 200 via the self-locking connection assembly 100. Specifically, the connecting hooks 110 of the self-locking connection assembly 100 are fixedly disposed on the compression unit 200, and both ends of the bandage are respectively connected to two bandage shafts 120, which are then fitted into the connecting hooks 110 on the corresponding sides.
