[0040] In order to thoroughly understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other implementation methods.

[0041] In the prior art, a mechanical chest compression device is a rescue medical device used for cardiopulmonary resuscitation, and its working principle is to drive its pressing machine assembly to press the patient's chest through a power source. The pressing machine assembly includes an insulating pressing head 2 and a metal pressing rod 1. In order to facilitate disassembly and assembly, the pressing head 2 and the pressing rod 1 are usually fixed with metal screws. The screws pass through the pressing head 2 and fix the pressing head 2 to the pressing rod 1. The head of the screw is exposed to the end of the pressing head 2 and is in contact with the pressing rod 1. Under this structure, when static electricity is generated at the pressing head 2, the metal screws and the metal pressing rod 1 as conductors are easy to introduce static electricity into the device, which may damage the electronic components in the device in severe cases. In the prior art, although a silicone sleeve is set on the pressing head 2 to prevent static electricity from being introduced during use, the silicone sleeve may become loose during use, and there is a risk of failure.

[0042] This embodiment provides a pressing machine assembly, such as Figure 1As shown, it includes: a pressing rod 1, a pressing head 2 and an insulating member 3; one side of the insulating member 3 is fixed to the pressing rod 1, and the other side is fixed to the pressing head 2.

[0043] Among them, the pressing rod 1 is a rod used for applying force in the pressing machine assembly, and in order to ensure strength, it can usually be made of metal material. The pressing head 2 is a component of the pressing machine assembly used for contacting the human body, and generally can be made of insulating materials, such as plastic, ceramic, or other materials, such as metal materials. The insulating member 3 is a connecting member made of insulating material, and its material properties cause it to not conduct static electricity. The pressing machine assembly provided in the embodiment of the present application can prevent the external static electricity contacted by the pressing head 2 from being conducted along the metal pressing rod 1 by providing the insulating member 3, thereby preventing static electricity from being transmitted into the device and damaging electronic components.

[0044] In an optional embodiment, if Figure 2 , Figure 3 As shown, the insulating member 3 includes a main body 31, the first side of the main body 31 is connected to the pressing rod 1, and the second side is connected to the pressing head 2, and the second side is the opposite side of the first side; the main body 31 has a first connection hole 311 and a second connection hole 312, the first connection hole 311 is used for the first fastener to pass through to connect the pressing rod 1 and the insulating member 3; the second connection hole 312 is used for the second fastener to pass through to connect the pressing head 2 and the insulating member 3; the first fastener and the second fastener do not contact. In this embodiment, the fastener and the connection hole connection method can facilitate the direct and quick connection or disassembly of the pressing rod 1, the pressing head 2 and the insulating member 3. Since the fasteners generally use screws, bolts, rivets and other components, which are generally made of metal, the first fastener and the second fastener do not contact each other in this solution. The first fastener and the second fastener are isolated by the insulating material of the insulating member 3, which can avoid the contact between the first fastener and the second fastener to form a conductive path, and prevent the static electricity touched by the pressing head 2 from being transmitted to the inside of the device through the second fastener, the first fastener and the pressing rod 1 in sequence to damage the electronic components.

[0045] In an optional embodiment, if Figure 3 As shown, the first connection hole 311 and the second connection hole 312 are arranged in a staggered manner. In this embodiment, through the above arrangement, on the one hand, it is ensured that the first fastener in the first connection hole 311 and the second fastener in the second connection hole 312 do not contact each other, and it is also convenient to set a plurality of first connection holes 311 or second connection holes 312, so that the plurality of holes can be spaced a sufficient distance apart, thereby ensuring that the structure of the main body 31 has sufficient strength.

[0046] In an optional embodiment, if Figure 2 As shown, the insulating member 3 further includes an embedding groove 32, and the embedding groove 32 is located on the first side of the main body 31; Figure 4As shown, the pressing rod 1 includes a rod body 11 and a connecting block 12 located at the end of the rod body 11, and the connecting block 12 is embedded in the embedding groove 32; the connecting block 12 has a third connecting hole 121; the third connecting hole 121 is used to communicate with the first connecting hole 311. In this embodiment, through the structure of the connecting block 12 embedded in the embedding groove 32, the side of the connecting block 12 is limited by the inner wall of the embedding groove 32 to a certain extent, which can be beneficial to the stability of the connection between the pressing rod 1 and the insulating member 3, improve the verticality between the pressing rod 1 and the insulating member 3, and can more easily ensure that the third connecting hole 121 is aligned and connected with the first connecting hole 311 for the first fastener to pass through, thereby improving the convenience during assembly. Specifically, as Figure 2 As shown, the inner wall of the embedding groove 32 includes a bottom wall and a side wall perpendicular to the bottom wall, the end of the connecting block 12 is limited by the bottom wall of the embedding groove 32, and the side wall of the connecting block 12 is limited by the side wall of the embedding groove 32.

[0047] In an optional embodiment, if Figure 2 As shown, three embedding slots 32 may be provided, such as Figure 4 As shown, the corresponding rod body 11 of the pressing rod 1 can be three. The embedding groove 32 and the pressing rod 1 can be arranged around the center of the insulating member 3 to improve the uniformity of the support. In this embodiment, the shape of the rod body 11 is sheet-like, which can reduce the dead weight. It can be understood that in other embodiments, the number of the embedding grooves 32 and the rod body 11 is not limited to three, and can also be 4, 5 or more, or 2 or 1, as long as the support requirements can be met.

[0048] In an optional embodiment, if Figure 4 As shown, three rod bodies 11 enclose a cavity, and the cavity can accommodate transmission components, and there is a gap between each rod body 11 for the transmission components to pass through. In this embodiment, the rod body 11 adopts a three-piece design, which can make the pressing rod 1 lightweight, and leave space inside the pressing rod 1 for the transmission components to be installed, making full use of the space, and the three-piece design also uses the gaps between the rod bodies 11 for the transmission components to pass through, for example, transmission structures such as synchronous belts, chains, racks, rockers, etc. can pass through the gaps to connect with components outside the cavity.

[0049] In an optional embodiment, if Figure 4 As shown, at least part of the connection block 12 has two third connection holes 121. Figure 2As shown, in this embodiment, the insulating member 3 has a plurality of embedding grooves 32. In order to stagger the first connection holes 311 and the second connection holes 312, the positions of some first connection holes 311 in the embedding grooves 32 are biased to the left or right. In order to make the manufactured connection block 12 universal, two third connection holes 121 with different positions are directly opened on the connection block 12, so that the connection block 12 can select one of the third connection holes 121 to align with the first connection hole 311 on the insulating member 3 during assembly for connection. It is understandable that as long as space allows, the number of the third connection holes 121 opened on the connection block 12 can be more than two. It is understandable that in other embodiments, there can be only one third connection hole 121 opened on the connection block 12, as long as it corresponds to the position of the first connection hole 311 during design.

[0050] In an optional embodiment, if Figure 2 , Figure 3 As shown, the first side and the second side of the main body 31 are provided with a plurality of staggered hollow holes 313. In this embodiment, the insulating member 3 is manufactured by injection molding. The provision of the hollow holes 313 can reduce the material consumption during the manufacturing of the insulating member 3 on the one hand, and can make the thickness of each part of the insulating member 3 basically consistent on the other hand, thereby avoiding shrinkage and deformation of the insulating member 3 during molding. Specifically, as Figure 3 As shown, in this embodiment, the hollow holes 313 of the second side of the main body 31 are arranged at the center and the edge, as shown in FIG. Figure 2 As shown, the hollow holes 313 on the first side of the main body 31 are arranged between the center and the edge. This arrangement structure can stagger the hollow parts on both sides of the main body 31 to avoid insufficient strength at some positions of the main body 31.

[0051] In an optional embodiment, if Figure 3 , Figure 5 , Figure 6 As shown, the insulating member 3 further includes a convex portion 33 located on the second side of the main body 31; one side of the pressing head 2 has a concave portion 21, and the convex portion 33 is embedded in the concave portion 21. In this embodiment, the convex portion 33 is embedded in the concave portion 21, which is beneficial to the stability of the pressing head 2 after being connected to the insulating member 3, and improves the coaxiality of the connection between the pressing head 2 and the insulating member 3; on the other hand, it is convenient for the second connection hole 312 to be quickly aligned with the fourth connection hole 22, which is convenient for assembly. The fourth connection hole 22 is a through hole opened in the pressing head 2, which is used for the second fastener to pass through.

[0052] In an optional embodiment, if Figure 3As shown, the insulating member 3 further includes a flange 34, which is arranged around the edge of the second side of the main body 31. After the insulating member 3 is connected to the pressing head 2, the flange 34 protrudes toward one side of the pressing head 2, which can prevent external dust from entering between the insulating member 3 and the pressing head 2. A rubber sleeve can also be fixed between the insulating member 3 and the pressing head 2, and the flange 34 can be used to compress the rubber sleeve to further prevent dust from entering the interior.

[0053] In an optional embodiment, if Figure 3 As shown, the insulating member 3 further includes a nail head receiving groove 35, which is located at the second side edge of the main body 31, and is aligned with the first connecting hole 311. In this embodiment, the nail head receiving groove 35 is used to receive the nail head of the screw, and the nail head of the screw used to connect the first connecting hole 311 can be received in the nail head receiving groove 35 after passing through the first connecting hole 311, so that the nail head is not exposed.

[0054] In an optional embodiment, if Figure 3 As shown, one side of the nail head receiving groove 35 has an opening. The opening structure can facilitate the removal of the nail head in the nail head receiving groove 35 when the pressing head 2 is disassembled, thereby facilitating the disassembly operation.

[0055] This embodiment provides a method for assembling the above-mentioned pressing machine assembly, comprising the following steps:

[0056] First, the connecting block 12 at one end of the pressing rod 1 is embedded in the embedding groove 32 of the insulating member 3, and then a screw is passed through the first connecting hole 311, and then the screw is tightened in the third connecting hole 121 to complete the fixing of the pressing rod 1 and the insulating member 3; repeat the above steps until all the pressing rods 1 are fixed;

[0057] The convex portion 33 of the insulating member 3 is inserted into the concave portion 21 of the pressing head 2 , and then a screw is passed through the fourth connecting hole 22 , and then the screw is tightened in the second connecting hole 312 , thereby completing the fixing of the pressing head 2 and the insulating member 3 .

[0058] This embodiment also provides a chest compression device, including the above-mentioned compression machine assembly. Electronic components are arranged inside the device, and the insulating member 3 arranged in the compression machine assembly can prevent the external static electricity contacted by the compression head 2 from being transmitted along the metal compression rod 1, thereby preventing the static electricity from entering the device and damaging the electronic components.

[0059] It should be understood that the above embodiments are exemplary and are not intended to include all possible implementations included in the claims. Various modifications and changes may be made on the basis of the above embodiments without departing from the scope of the present disclosure.
