A patch diaphragm pacemaker

Abstract

The application discloses a patch diaphragm pacemaker and belongs to the technical field of medical devices. The patch diaphragm pacemaker comprises a main machine, electrode pads and an adapter block. The adapter block is provided with two large electrode sockets and two small electrode sockets. A large electrode lock plate is arranged on one side of the large electrode socket and is slidably connected with the adapter block through a middle sliding plate. A small electrode lock plate is arranged on one side of the small electrode socket and is slidably connected with the adapter block through a side sliding plate. An elastic assembly is hingedly connected between the middle sliding plate and the side sliding plate, and the direction of the elastic assembly is changed along with the relative sliding of the middle sliding plate and the side sliding plate. When the middle sliding plate and the side sliding plate are farthest away from each other, the elastic assembly is in a spring-open position. When the middle sliding plate and the side sliding plate are closest to each other, the elastic assembly is in a locking position. In an initial state, the elastic assembly is in the spring-open position, so that the electrode pad plug can be inserted into the socket. After being inserted, the elastic assembly is automatically turned to the locking position, so that a certain pressure is kept between the plug and the socket, and the stability of the electrode pad connection is improved.

[0009] An elastic component is hinged between the middle sliding plate and the side sliding plate;

[0010] When the distance between the middle slide plate and the side slide plate is the greatest, the elastic component is in the open position, and the elastic component pushes the middle slide plate and the side slide plate away from each other; when the distance between the middle slide plate and the side slide plate is the closest, the elastic component is in the locked position, and the elastic component pushes the middle slide plate and the side slide plate closer to each other.

[0011] Furthermore, the lower side of the adapter block is provided with a sliding groove for the middle sliding plate and the side sliding plate to slide, and a bottom plate covering the sliding groove is fixed to the lower side of the adapter block.

[0012] The adapter block extends from the front end of the middle slide plate and is fixed to the large electrode locking plate;

[0013] The rear end of the side slide plate extends through the adapter block and is fixed to the small electrode locking plate.

[0014] The adapter block has a side guide protrusion on each side of its rear end face, and a side guide groove is provided on the side guide protrusion. The side slide plate slides through the side guide groove.

[0015] The side of the side slide plate has a rear limiting platform to prevent the side slide plate from sliding out of the side guide groove;

[0016] The adapter block has a central guide protrusion at the middle of its front end face, and a central guide groove is provided on the central guide protrusion. The central sliding plate slides through the central guide groove.

[0017] The middle slide plate has a front limiting platform on its side to prevent it from sliding out of the middle guide groove.

[0018] The two large electrode sockets are located on both sides of the central guide protrusion, and the large electrode sockets do not extend beyond the front end of the central guide protrusion;

[0020] The elastic component includes elastic push rods disposed on both sides of the middle slide plate, one end of the elastic push rod being hinged to the side of the middle slide plate, and the other end of the elastic push rod being hinged to the corresponding side slide plate.

[0021] The elastic push rod is fixed with hinge pins at both ends, and the center of each end of the hinge pin has a protrusion.

[0022] The middle slide plate has a through hole, and a flared opening connected to the through hole is provided on the side of the middle slide plate; the hinge column is rotatably installed in the through hole, and the protrusions at both ends of the hinge column abut against the bottom surface of the slide groove and the inner surface of the base plate, respectively.

[0023] Two parallel elastic push rods are provided on each side of the middle slide plate, and the elastic push rods on both sides of the middle slide plate are symmetrical along the center line of the middle slide plate.

[0024] The adapter block contains a circuit board, and the large electrode socket and the small electrode socket are connected to the circuit board; a connector to the circuit board is installed on one side of the adapter block, and the connector is connected to the host via a cable.

[0028] An elastic sheet is fixed on the side of the clamping platform away from the adapter block; the elastic sheet is attached to the side of the square column, and the middle part of the elastic sheet has an arc-shaped part that mates with the arc-shaped groove.

[0029] The beneficial effects of this invention are as follows:

[0030] The diaphragm pacemaker connects to the electrode pads via the large and small electrode sockets on the adapter block, making the electrode pad connection more modular and easier to replace and maintain. The large and small electrode sockets are arranged in an alternating and parallel manner, and together with the middle and side guide protrusions on both sides and the large and small electrode locking plates, they form an enclosed structure to prevent the plug from being accidentally touched and loosened.

[0031] By creating sliding grooves, side guide grooves, and center guide grooves on the adapter block, and by setting a limiting platform and a base plate, the stable sliding of the large electrode locking plate and the small electrode locking plate is ensured. The elastic component is connected to the center slide plate and the side slide plate by a hinge, realizing automatic rotation and locking during the sliding process. In the initial state, the elastic component is in the spring-open position, which makes it easy to insert the electrode plug into the socket. After insertion, the elastic component automatically rotates to the locked position to maintain a certain pressure between the plug and the socket, thereby improving the stability of the electrode connection.

[0032] The clamping base securely holds the plug by cooperating with the clamping platform and the elastic plate; the plug of the electrode plate can be easily inserted by pushing the large electrode locking plate and the small electrode locking plate inward; when it is necessary to remove it, the plug can be unlocked and removed by pulling the locking plate outward, making the operation simple and quick.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Example 1:

[0053] Combination Figures 1 to 4 As shown, this invention provides a patch-type diaphragm pacemaker, mainly comprising a main unit 1, an adapter block 3, and electrode pads 2. A circuit board is fixed inside the adapter block 3. Two large electrode sockets 31 are fixed to the front end of the adapter block 3, and two small electrode sockets 32 are fixed to the rear end. Both the large and small electrode sockets 31 and 32 are electrically connected to the circuit board, and are arranged alternately and parallel to each other. The electrode pads 2 are connected to plugs 21 via cables, and the plugs 21 of the four electrode pads 2 are correspondingly inserted into the two large electrode sockets 31 and the two small electrode sockets 32. A connector 37, electrically connected to the circuit board, is also fixed on one side of the adapter block 3, and the connector 37 is connected to the main unit 1 via a cable.

[0054] Combination Figures 2 to 6 As shown, the large electrode locking plate 4 is arranged on one side of the large electrode socket 31. A middle sliding plate 41 perpendicular to the large electrode locking plate 4 is fixed in the middle of the large electrode locking plate 4. The middle sliding plate 41 is slidably inserted into the adapter block 3. A clamping seat 7 opposite to the large electrode socket 31 is fixed at each end of the large electrode locking plate 4. In use, the plugs 21 of the two large electrode plates 2 are snapped into the clamping seat 7.

[0055] The small electrode locking plate 5 is arranged on one side of the small electrode socket 32. A side slide plate 51 perpendicular to the small electrode locking plate 5 is fixed to each end of the small electrode locking plate 5. The side slide plates 51 are slidably inserted into the adapter block 3. Inside the adapter block 3, the two side slide plates 51 are arranged parallel to each other on both sides of the middle slide plate 41. Two clamping seats 7 opposite to the small electrode socket 32 ​​are fixed in the middle of the small electrode locking plate 5; in use, the plugs 21 of the two small electrode pieces 2 are snapped onto the clamping seats 7.

[0056] Inside the adapter block 3, an elastic component 6 is hinged between the middle sliding plate 41 and the side sliding plate 51. During the relative sliding process of the middle sliding plate 41 and the side sliding plate 51, the direction of the elastic component 6 changes accordingly, such that: when the middle sliding plate 41 and the side sliding plate 51 are at their farthest distance, the elastic component 6 is in the open position, and the elastic force of the elastic component 6 pushes the middle sliding plate 41 and the side sliding plate 51 away from each other; when the middle sliding plate 41 and the side sliding plate 51 are at their closest distance, the elastic component 6 is in the locked position, and the elastic force of the elastic component 6 pushes the middle sliding plate 41 and the side sliding plate 51 closer to each other.

[0057] Working principle: Combining Figure 6 and Figure 7 As shown, in the initial state, the elastic component 6 is in the spring-open position, and the large electrode locking plate 4 and the small electrode locking plate 5 are away from the adapter block 3. In use, the plugs 21 of the four electrode pieces 2 are snapped onto the corresponding clamping seats 7, with the ends of the plugs 21 facing or slightly entering the corresponding large electrode socket 31 and small electrode socket 32. At the same time, the large electrode locking plate 4 and the small electrode locking plate 5 are pressed inward, causing the plugs 21 to be inserted into the large electrode socket 31 and the small electrode socket 32. The elastic component 6 slowly rotates. After the plugs 21 are inserted into the large electrode socket 31 and the small electrode socket 32, the elastic component 6 is in the locked position. The elastic component 6 pushes the large electrode locking plate 4 and the small electrode locking plate 5 to move inward and hold, pressing the plugs 21 on both sides to ensure that the electrode pieces 2 are in a stable connection state.

[0058] Example 2:

[0059] Based on the above embodiment one, combined with Figures 2 to 7 As shown, in order to ensure the stable sliding of the large electrode locking plate 4 and the small electrode locking plate 5, a sliding groove 33 is provided on the lower side of the adapter block 3; a side guide protrusion 35 is provided on the left and right sides of the rear end face of the adapter block 3, and a side guide groove 351 connecting the sliding groove 33 and the rear end face of the side guide protrusion 35 is provided on the side guide protrusion 35; a middle guide protrusion 36 is provided at the middle position of the front end face of the adapter block 3, and a middle guide groove 361 connecting the sliding groove 33 and the front end face of the middle guide protrusion 36 is provided on the middle guide protrusion 36.

[0060] The middle sliding plate 41 slides through the middle guide groove 361, and the side sliding plate 51 slides through the side guide groove 351. To prevent the middle sliding plate 41 and the side sliding plate 51 from detaching from the adapter block 3, a rear limiting platform 511 is provided on the inner side of the side sliding plate 51 to prevent the side sliding plate 51 from sliding out of the side guide groove 351. A front limiting platform 411 is provided on both sides of the middle sliding plate 41 to prevent the middle sliding plate 41 from sliding out of the middle guide groove 361. A base plate 34 is fixed to the lower side of the adapter block 3 by bolts. The base plate 34 covers the sliding groove 33, the side guide groove 351 and the middle guide groove 361, and limits the middle sliding plate 41 and the side sliding plate 51.

[0061] Two large electrode sockets 31 are positioned on either side of the central guide protrusion 36. The large electrode sockets 31 do not extend beyond the front end of the central guide protrusion 36 and are protected between the central guide protrusion 36 and the large electrode locking plate 4 to prevent contact. Two small electrode sockets 32 are positioned between two side guide protrusions 35. The small electrode sockets 32 do not extend beyond the rear end of the side guide protrusions 35 and are protected between the side guide protrusions 35 and the small electrode locking plate 5 to prevent contact.

[0062] Combination Figures 6 to 9 As shown, the elastic component 6 includes four elastic push rods 61 arranged in pairs on both sides of the middle slide plate 41. The elastic push rods 61 on each side are parallel to each other, and the elastic push rods 61 on both sides are symmetrical along the center line of the middle slide plate 41.

[0063] The two ends of the elastic push rod 61 are hinged to the sides of the middle sliding plate 41 and the side sliding plate 51, respectively. Taking the hinge structure between the elastic push rod 61 and the middle sliding plate 41 as an example:

[0064] The elastic push rod 61 has hinge posts 611 fixed at both ends, and each end of the hinge post 611 has a protrusion 612 at its center. A sliding hole 413 is provided on the middle slide plate 41 near the side, and the sliding hole 413 penetrates the middle slide plate 41 in the thickness direction. A flared opening 412 is provided on the side of the middle slide plate 41, and the inner end of the flared opening 412 is connected to the sliding hole 413, so that the sliding hole 413 forms an open structure, but the circumference of the sliding hole 413 is kept to more than half. The hinge post 611 is rotatably installed in the sliding hole 413, and the protrusions 612 at both ends of the hinge post 611 abut against the bottom surface of the slide groove 33 and the inner surface of the base plate 34, respectively. The end of the elastic push rod 61 is located in the flared opening 412. When the hinge post 611 rotates in the sliding hole 413, the end of the elastic push rod 61 can swing in the flared opening 412 to ensure that the flared opening 412 rotates smoothly.

[0065] Working principle: Combining Figure 6 and Figure 7 As shown, when the elastic push rod 61 is in the open position, the end of the elastic push rod 61 connected to the side slide plate 51 is at the rear, and the elastic push rod 61 provides elastic force to push the middle slide plate 41 and the side slide plate 51 away from each other; when the middle slide plate 41 and the side slide plate 51 are pushed inward, the elastic push rod 61 slowly rotates until the end of the elastic push rod 61 connected to the side slide plate 51 is in front. At this time, the elastic push rod 61 is in the locked position, and the elastic push rod 61 provides elastic force to push the middle slide plate 41 and the side slide plate 51 to keep them close to each other, pressing the plug 21 on both sides and the large electrode socket 31 and the small electrode socket 32.

[0066] Example 3:

[0067] Based on the above embodiments one or two, combined with Figures 2 to 4 ,as well as Figure 10 As shown, the plug 21 has a square post 211 in the middle; there is a limiting step 212 on each side of the end of the square post 211, and an arc groove 213 is provided in the middle of both sides of the square post 211.

[0068] Taking a clamping seat 7 at the end of the large electrode locking plate 4 as an example: The clamping seat 7 includes a pair of clamping platforms 71 fixed on the large electrode locking plate 4. When the plug 21 is clamped onto the clamping seat 7, the clamping platform 71 fits perfectly against both sides of the square post 211. A positioning stop 711 is provided on one side of the clamping platform 71, and the positioning stop 711 cooperates with the limiting step 212. An elastic sheet 72 is fixed on the other side of the clamping platform 71. The elastic sheet 72 has an arc-shaped part 721 in the middle. The elastic sheet 72 fits against the side of the square post 211, and the arc-shaped part 721 is pressed into the arc-shaped groove 213.

[0069] Working principle: Combining Figure 2 , Figure 6 and Figure 10 As shown, after clamping the plug 21 into the clamping seat 7, by pushing the large electrode locking plate 4 and the small electrode locking plate 5 on both sides inward, the plug 21 can be inserted into the corresponding large electrode socket 31 and small electrode socket 32, and remain locked under the pushing force of the elastic component 6. When it is necessary to pull out the plug 21, the small electrode locking plate 5 can be pulled outward. After the small electrode locking plate 5 moves away from the adapter block 3, the elastic component 6 rotates, which can further push the large electrode locking plate 4 outward. At this time, the plug 21 of the four electrode pieces 2 can be pulled out.

[0070] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
