[0040] See also Figures 1 to 4 The present application provides a pressing gasket 100 , which is applied to a pressing structure 10 . Figure 1 This is a three-dimensional diagram of the pressing structure 10 of the present application viewed from one angle. Figure 2 for Figure 1 The pressing structure 10 is shown in a three-dimensional view from another angle. Figure 3 for Figure 1 The pressing structure 10 is shown in a three-dimensional view from another angle. Figure 4 for Figure 1 The exploded schematic diagram of the pressing structure 10 is shown. The pressing structure 10 is applied to a cardiopulmonary resuscitation machine, and the pressing structure 10 is installed in the instrument host of the cardiopulmonary resuscitation machine, and the instrument host can control the movement of the pressing structure 10 so that the pressing structure 10 performs a pressing operation to achieve the purpose of cardiopulmonary resuscitation.

[0041] It is understandable that silicone gaskets are usually pressed as consumables and used one-to-one with patients to avoid cross infection and facilitate replacement. At present, the pressing head gasket is arranged at one end of the pressing head. The pressing gasket is easy to fall off from the pressing head after being subjected to force and vibration for a long time, which will affect the pressing effect of the pressing head and thus affect the performance of the cardiopulmonary resuscitation machine. To this end, the present application provides a new type of pressing gasket 100, which can avoid falling off due to vibration, ensure reliable fixation to the pressing head 200, avoid secondary damage to the patient, so as to ensure the pressing effect and the performance of the cardiopulmonary resuscitation machine. The specific structure of the pressing structure 10 is first introduced below, and then the specific structure of the pressing gasket 100 is introduced.

[0042] See also Figures 1 to 4 The present application provides a pressing structure 10, which includes a pressing push rod 300, a pressing head 200 and a flexible pressing pad 100. The pressing head 200 is detachably arranged at the end of the pressing push rod 300 and can move with the pressing push rod 300. The pressing push rod 300 is the main part of the pressing structure 10, and the pressing push rod 300 is arranged along the height direction (up and down direction), such as Figure 1 As shown, the height direction is also the pressing direction of the push rod 300.

[0043] The bottom of the pressing push rod 300 can be detachably mounted with the pressing head 200, which is the main component for achieving pressing. The top of the pressing push rod 300 can be detachably mounted to the instrument host, and the instrument host can control the pressing push rod 300 to move up and down. When the pressing push rod 300 moves up and down, it can drive the pressing head 200 to move up and down synchronously, thereby performing the pressing operation and achieving the purpose of cardiopulmonary resuscitation. It is worth noting that the instrument host controlling the lifting and lowering movement of the pressing push rod 300 is a prior art and will not be repeated here.

[0044] In order to ensure the pressing effect and avoid cross infection, the pressing structure 10 of the present application further includes a pressing pad 100, which is detachably arranged at one end of the pressing head 200 away from the pressing push rod 300. When the pressing structure 10 is used for cardiopulmonary resuscitation, the pressing push rod 300 drives the pressing head 200 to directly contact the patient's chest cavity through the pressing pad 100 to perform the pressing operation.

[0045] After the pressing structure 10 completes the cardiopulmonary resuscitation, the pressing pad 100 is removed from the pressing head 200 and replaced with a new pressing pad 100 for the next use. In this way, the pressing pad 100 can be used as a consumable material with the patient one-to-one, avoiding cross infection, and is easy to replace, avoiding frequent cleaning when rescuing many patients, thereby improving the use efficiency.

[0046] The pressing pad 100 is made of a flexible material, which can prevent the pressing pad 100 from scratching the patient's chest, and can ensure the comfort during pressing to avoid causing harm to the patient. The pressing pad 100 has surfaces that are separated from each other, one surface of the pressing pad 100 is connected to the pressing head 200, and the other surface of the pressing pad 100 is in contact with the patient's chest. Optionally, the pressing pad 100 is made of a silicone material. Of course, in other embodiments of the present application, the pressing pad 100 can also be made of rubber, nylon or other flexible materials.

[0047] After the pressing structure 10 of the present application adopts the pressing gasket 100 of the present application, it can ensure that the pressing gasket 100 is reliably fixed to the pressing head 200. When the pressing push rod 300 drives the pressing head 200 and the pressing gasket 100 to perform a pressing operation, it can prevent the pressing gasket 100 from falling off the pressing head 200 due to vibration, thereby avoiding secondary injury to the patient, thereby ensuring the pressing effect of the pressing head 200 and ensuring the performance of the cardiopulmonary resuscitation machine.

[0048] See also Figures 1 to 7 In one embodiment, the pressing gasket 100 includes a gasket body 110 and a connector 120 . The connector 120 is disposed on one side of the gasket body 110 and is used to accommodate the pressing head 200 . The connector 120 is covered on the outer side of the pressing head 200 . Figure 5 for Figure 1 The schematic diagram of the pressing pad 100 in the pressing structure 10 shown is viewed from an angle. Figure 6 for Figure 5 The front view of the pressing pad 100 is shown, Figure 7 for Figure 1 A cross-sectional view of the pressing structure 10 is shown.

[0049] The connector 120 is protrudingly disposed on a surface of the gasket body 110. The gasket body 110 is the main structure of the pressing gasket 100. The gasket body 110 has opposite surfaces. The front of the gasket body 110 is the surface away from the pressing head 200, and the back of the gasket body 110 is the surface facing the pressing head 200. The front of the gasket body 110 is the front (the other surface) of the pressing gasket 100, and the front of the gasket body 110 directly fits against the patient's chest.

[0050] A connector 120 is provided on the back of the gasket body 110, and the connector 120 is hollow. When the pressing gasket 100 is connected to the pressing head 200, the pressing head 200 is located in the connector 120, and the connector 120 can at least partially cover the outside of the pressing head 200. In this way, the connector 120 can be fixed to the pressing head 200 by the covering setting, so that the pressing gasket 100 is fixed to the pressing head 200. When the pressing push rod 300 drives the pressing head 200 to press, the pressing head 200 can perform a pressing operation through the pressing gasket 100, and due to the covering fixing method adopted between the pressing gasket 100 and the pressing head 200, the pressing gasket 100 can be reliably fixed to the pressing head 200, and will not be separated from the pressing head 200 due to the vibration force, thereby ensuring the pressing effect.

[0051] The pressing pad 100 of the above embodiment is provided with a connector 120 on one side of the pad body 110 of the pressing pad 100. The connector 120 can at least partially cover the pressing head 200. The covering force of the connector 120 realizes the connection between the connector 120 and the pressing head 200, thereby fixing the pressing pad 100 to the pressing head 200. When the pressing push rod 300 drives the pressing head 200 and the pressing pad 100 to perform the pressing operation, the connector 120 can reliably fix the pressing pad 100 to the pressing head 200, preventing the pressing pad 100 from falling off the pressing head 200 due to vibration, etc., thereby avoiding secondary damage to the patient, thereby ensuring the pressing effect of the pressing head 200 and ensuring the performance of the cardiopulmonary resuscitation machine.

[0052] Optionally, the connector 120 and the gasket body 110 are an integral structure. That is, the connector 120 and the gasket body 110 are integrally formed to ensure the structural strength of the pressing gasket 100, thereby ensuring the performance of the pressing gasket 100, and at the same time, simplifying the production process and improving production efficiency.

[0053] Optionally, the shape of the connector 120 is adapted to the shape of the pressing head 200. In other words, the shape of the connector 120 is substantially the same as the shape of the pressing head 200. In this way, the connector 120 can be tightly wrapped around the outside of the pressing head 200 to ensure the matching effect between the connector 120 and the pressing head 200, so that the connector 120 reliably covers the pressing head 200, thereby making the pressing gasket 100 reliably fixed to the pressing head 200. Exemplarily, the connector 120 is arranged in a hollow cylindrical shape, and the entire pressing head 200 is also arranged in a cylindrical shape.

[0054] See also Figures 4 to 7 In one embodiment, the inner diameter of the connector 120 is smaller than the diameter of the pressing head 200. In other words, the connector 120 and the pressing head 200 are in an interference fit relationship. After the pressing head 200 is installed on the connector 120, the pressing head 200 can tension the connector 120, so that the connector 120 is reliably fixed to the outside of the pressing head 200 and will not slip off from the outside of the pressing head 200.

[0055] See also Figure 1 , Figures 4 to 7 In one embodiment, the height dimension of the connection head 120 is greater than or equal to the height dimension of the pressing head 200. In other words, the connection head 120 is completely covered on the outside of the pressing head 200, so that the reliability of the connection between the connection head 120 and the pressing head 200 can be ensured, so that the pressing gasket 100 is reliably fixed to the pressing head 200, and the pressing head 200 is prevented from falling off from the pressing head 200 under the action of vibration force.

[0056] Of course, in other embodiments of the present application, the height dimension of the connector 120 covering the pressing head 200 is greater than or equal to half the height of the pressing head 200. In other words, the connector 120 covers at least half of the pressing head 200, so that the connector 120 can be fixed to the outside of the pressing head 200.

[0057] See also Figure 1 , Figures 4 to 9 In one embodiment, the end of the connector 120 away from the pressing gasket 100 has a fixed edge 121, which extends toward the inner side of the connector 120 and protrudes from the inner wall of the connector 120. The fixed edge 121 can fix and limit the pressing head 200 located in the connector 120. Figure 8 for Figure 6 The cross-sectional view of the pressing pad 100 at AA is shown, Fig. 9 for Figure 6 The cross-sectional view of the pressing pad 100 is shown at BB.

[0058] The fixed edge 121 is located at the upper edge of the connector 120, that is, the flange, clamping edge, etc. of the connector 120. The fixed edge 121 extends toward the inner side of the connector 120 in the radial direction and is protruded from the inner wall of the connector 120. When the pressing head 200 is installed on the connector 120, the fixed edge 121 is located at one end of the pressing head 200. The fixed edge 121 can block the pressing head 200 to axially limit the pressing head 200, prevent the pressing head 200 from being separated from the connector 120, and thus prevent the pressing gasket 100 from falling off the pressing head 200.

[0059] Optionally, the fixed edge 121 and the connector 120 are an integral structure. In other words, the fixed edge 121 and the connector 120 are formed by an integral molding method to ensure the structural strength of the pressing gasket 100 and simplify the production process.

[0060] See also Figure 1 , Figures 4 to 9 In one embodiment, the end surface of the fixed edge 121 away from the pressing gasket 100 is a guide surface 122, and the guide surface 122 is used to guide the pressing head 200 to be installed in the connector 120. That is to say, the guide surface 122 is located on the upper surface of the fixed edge 121, and the guide surface 122 is inclined toward the inner side of the connector 120 along the radial direction. The guide surface 122 can play a guiding role to guide the installation of the pressing head 200. When the pressing head 200 is installed, the end surface of the pressing head 200 can move along the guide surface 122 and squeeze the fixed edge 121 to be installed in the connector 120. The guide surface 122 can facilitate the installation of the pressing head 200 in the connector 120.

[0061] In one embodiment, the inner wall of the connector 120 has a first matching portion, the outer peripheral surface of the pressing head 200 has a second matching portion, and the first matching portion and the second matching portion are matched and connected. In other words, corresponding matching structures are provided on the inner wall of the connector 120 and the outer peripheral surface of the pressing head 200. After the pressing head 200 is installed on the connector 120, the connector 120 can be further connected through the corresponding matching structure to ensure that the pressing gasket 100 is reliably fixed to the pressing head 200.

[0062] Specifically, the inner wall of the connector 120 is provided with a first matching portion, and the outer peripheral surface of the pressing head 200 has a second matching portion, and the positions of the first matching portion and the second matching portion correspond to each other. When the pressing head 200 is installed in the connector 120, the first matching portion can match with the second matching portion to achieve further fixation between the connector 120 and the pressing head 200.

[0063] Optionally, the first matching portion and the second matching portion are a protrusion and a groove. Optionally, the first matching portion is a protrusion, the second matching portion is a groove, and the first matching portion can be installed in the second matching portion. Optionally, the first matching portion is a circular protrusion, and the shape of the second matching portion is adapted to the first matching portion. Of course, the first matching portion can also be a convex ridge, and the second matching portion is correspondingly a strip-shaped groove to adapt to the convex ridge. Of course, in other embodiments of the present application, the first matching portion can also be a groove, and the second matching portion can be a protrusion.

[0064] Optionally, the first matching portion and the second matching portion are a matching structure of protrusions. Optionally, the first matching portion and the second matching portion are multiple protrusions arranged in an array, and the protrusions increase the friction between the connector 120 and the pressing head 200 to prevent the pressing gasket 100 from falling off the pressing head 200. Optionally, the first matching portion and the second matching portion can also be multiple annular ridges, and the pressing gasket 100 is limited by the clamping between the annular ridges.

[0065] Of course, in other embodiments of the present application, other structural forms, such as damping, may also be provided between the connecting head 120 and the pressing head 200 to increase the friction between the connecting head 120 and the pressing head 200, so as to ensure that the connecting head 120 is reliably fixed to the pressing head 200 and prevent the pressing gasket 100 from falling off the pressing head 200.

[0066] See also Figures 4 to 10 In one embodiment, the pressing gasket 100 also includes a plurality of fixing protrusions 130, which are arranged on a surface of the pressing gasket 100 and located on the inner side of the connecting head 120. The pressing head 200 has a plurality of matching grooves 210 corresponding to the fixing protrusions 130, and the fixing protrusions 130 can be plugged and installed in the corresponding matching grooves 210. Fig.10 for Figure 4A cross-sectional view of the pressing structure 10 is shown.

[0067] A plurality of fixing protrusions 130 are protrudingly arranged on the back side of the gasket body 110 and are located on the inner side of the connector 120, that is, the connector 120 is arranged around the plurality of fixing protrusions 130. The bottom of the pressing head 200 has a plurality of matching grooves 210, and the plurality of matching grooves 210 are distributed corresponding to the plurality of fixing protrusions 130, and each fixing protrusion 130 can be plugged and installed into the corresponding matching groove 210. In this way, the pressing gasket 100 can be installed on the pressing head 200 through the plug-in connection between the plurality of fixing protrusions 130 and the plurality of matching grooves 210. At the same time, the fixing method of the matching connector 120 covering the pressing head 200 can make the pressing gasket 100 and the pressing head 200 reliably connected in a double fixing manner, so as to avoid the pressing gasket 100 from falling off due to the vibration force during the pressing first aid process and causing secondary damage to the patient, thereby ensuring the pressing effect.

[0068] Optionally, the plurality of fixing protrusions 130 are evenly distributed along the circumference of the connector 120. In this way, the plurality of fixing protrusions 130 can be evenly connected to the pressing head 200, ensuring that the force between the pressing pad 100 and the pressing head 200 is evenly distributed, avoiding the situation where the pressing pad 100 falls off due to uneven force caused by uneven distribution, and ensuring that the pressing pad 100 is controllably fixed. Exemplarily, the number of the fixing protrusions 130 is three, and the three fixing protrusions 130 are evenly distributed, and accordingly, the number of the matching grooves 210 is also three.

[0069] See also Figures 4 to 10 In one embodiment, the fixing protrusion 130 includes a first fixing column 131 and a second fixing column 132. The first fixing column 131 is disposed on a surface of the pressing gasket 100, and the second fixing column 132 is disposed on the first fixing column 131. The diameter of the second fixing column 132 is greater than the diameter of the first fixing column 131.

[0070] That is, the fixing protrusion 130 is divided into two parts, namely, a first fixing column 131 and a second fixing column 132. The first fixing column 131 is arranged on the back of the pressing pad 100, and the second fixing column 132 is arranged on the first fixing column 131. Moreover, the diameter of the second fixing column 132 is larger than the diameter of the first fixing column 131, so as to form a fixing protrusion 130 with a thick top and a thin bottom. When the fixing protrusion 130 is installed in the matching groove 210, the second fixing column 132 can be clamped into the matching groove 210, so that the pressing pad 100 is fixed to the pressing head 200.

[0071] See also Figures 4 to 10In one embodiment, the mating groove 210 includes a first mating hole and a second mating hole, the first mating hole and the second mating hole are arranged on the pressing head 200 and are connected, the diameter of the second mating hole is larger than the diameter of the first mating hole, the second fixing column 132 can be plugged in and installed in the second mating hole, and the first fixing column 131 can be plugged in and installed in the first mating hole.

[0072] In one embodiment of the present application, the shape of the mating groove 210 is consistent with the shape of the fixing protrusion 130, that is, the mating groove 210 is distributed into parts, distributed as a first mating hole and a second mating hole, the second mating hole is arranged above the first mating hole, and the diameter of the second mating hole is larger than the diameter of the first mating hole to form a mating groove 210 that is thick at the top and thin at the bottom.

[0073] When the fixing protrusion 130 is installed in the matching groove 210, the second fixing column 132 first moves into the first matching hole, and continues to apply force to the pressing head 200 and the pressing pad 100, so that the second fixing column 132 gradually moves into the second matching hole. When the second fixing column 132 is installed in place in the second matching hole, the second fixing column 132 is located in the second matching hole, and the first fixing column 131 is located in the first matching hole.

[0074] Moreover, since the diameter of the second matching hole is larger than that of the first matching hole, a limiting step can be formed at the connection between the second matching holes. After the second fixing column 132 is installed in the second matching hole, the bottom surface of the second fixing column 132 can be clamped on the limiting step to limit the fixing protrusion 130 and prevent the fixing protrusion 130 from falling out of the first matching hole.

[0075] Exemplarily, the first fixing column 131 is provided in a columnar shape, and the second fixing column 132 is provided in an inverted cone shape. That is, the inverted cone-shaped second fixing column 132 is provided on the first fixing column 131 to form the fixing protrusion 130. The diameter of the inverted cone-shaped second fixing column 132 gradually increases from top to bottom to play a role in guiding the installation. When the fixing protrusion 130 is installed in the matching groove 210, the inverted cone-shaped second fixing column 132 can be gradually installed in the first matching hole, and gradually move along the first matching hole to be inserted into the second matching hole.

[0076] In other embodiments of the present application, the first fixing column 131 and the second fixing column 132 may both be columnar, or the first fixing column 131 and the second fixing column 132 may both be inverted cones. Of course, in other embodiments of the present application, the outer periphery of the fixing protrusion 130 may also be directly provided with a limiting protrusion, etc., to limit the matching groove 210. Optionally, the first fixing column 131 and the second fixing column 132 are an integral structure.

[0077] See also Figure 2 , Figure 6 and Fig.11 In one embodiment, the pressing gasket 100 further has a protrusion 140 , and the protrusion 140 is protrudingly disposed on a surface of the pressing gasket 100 facing away from the connector 120 . Fig.11 for Figure 5 The pressing pad 100 is shown as a schematic diagram viewed from another angle.

[0078] The protrusion 140 is arranged on the front side of the pressing pad 100. When the pressing push rod 300 drives the pressing head 200 and the pressing pad 100 to contact the patient, the pressing pad 100 can contact the chest cavity of the patient through the protrusion 140, and the protrusion 140 can increase the contact friction between the pressing pad 100 and the patient, and improve the anti-slip ability between the pressing pad 100 and the patient, thereby preventing the pressing pad 100 from slipping and deviating, so as to ensure the pressing effect of the pressing pad 100.

[0079] See also Figure 2 and Fig.11 In one embodiment, the number of the protrusions 140 is multiple, and the multiple protrusions 140 are arranged in rows and columns on the surface of the pressing pad 100. The multiple protrusions 140 can increase the friction between the pressing pad 100 and the patient's skin, avoid slipping and displacement, and ensure the pressing effect. Optionally, the multiple protrusions 140 cover the front of the pressing pad 100. In this way, the contact area between the pressing pad 100 and the patient can be ensured. Optionally, the multiple protrusions 140 are evenly or unevenly distributed.

[0080] See also Figure 2 and Fig.11 In one embodiment, the edge of the protrusion 140 is rounded. In other words, the protrusion 140 has no edge design. When the silicone gasket contacts the patient, the protrusion 140 can directly fit the patient's chest without scratching the patient's skin, thereby avoiding secondary damage to the patient. Optionally, the protrusion 140 is spherical. Of course, in other embodiments of the present application, the protrusion 140 may also be cylindrical with edges or other structures that can avoid slipping.

[0081] The pressing pad 100 of the present application is provided with a connector 120 on the back of the pad body, and the connector 120 can cover and clamp the pressing head 200. At the same time, a plurality of fixing protrusions 130 are also provided on the back of the pad body. The plurality of fixing protrusions 130 are located on the inner side of the connector 120 and are clamped and matched with the matching groove 210 of the pressing head 200, so as to realize the double fixation of the pressing pad 100 and the pressing head 200, so as to ensure that the pressing pad 100 is reliably fixed to the pressing head 200, and to prevent the pressing pad 100 from falling off from the pressing head 200 and causing secondary damage to the patient. At the same time, a plurality of protrusions 140 are provided on the front of the pressing single piece, and the plurality of protrusions 140 can ensure that the friction with the patient can be increased, and slippage and displacement can be avoided, so as to ensure the pressing effect.
