Description

Technical Field

[0001] The present invention relates to the field of medical technology, in particular to a special electrocardiogram treatment vehicle with a wire arranging device. Background Art

[0002] Electrocardiographs (ECGs) require multiple lead wires for clinical diagnosis. These devices are usually placed on ordinary treatment carts for transportation and use. However, ordinary treatment carts lack a structural design specifically for managing and organizing lead wires, which makes it very easy for lead wires to become entangled and knotted during storage and movement.

[0003] When medical staff perform electrocardiograms, they must spend a lot of time untangling and knotting lead wires one by one and accurately placing them at the corresponding positions on the patient's body. This process is cumbersome and time-consuming, significantly reducing work efficiency and may delay diagnosis, especially in emergency situations.

[0004] In addition, during the storage and sorting process after each use, in order to prevent the lead wires from becoming tangled, medical staff have to use repeated winding and knotting to fix them. This non-standardized sorting method is extremely inconvenient to operate, and the repeated winding and knotting will exert continuous twisting and pulling forces on the lead wires. Long-term accumulation can easily cause damage to the internal core of the lead wire, damage to the insulation layer, or external deformation, leading to poor contact. Summary of the Invention

[0005] In view of the above problems or problems existing in the prior art, the inventors have proposed the present invention.

[0006] Therefore, the purpose of the present invention is to provide a special electrocardiogram treatment vehicle with a wire management device, which solves the problem that the lead wires of existing electrocardiographs are tangled and knotted during use, affecting the use of medical staff.

[0010] The slip ring and the fixed sleeve are linked together by the guide rod and the waist hole. When the fixed sleeve makes a linear motion in the vertical direction, the guide rod is driven to slide in the waist hole, thereby forcing the slip ring to rotate around its own axis.

[0011] As a preferred embodiment of the electrocardiogram treatment vehicle with a cable management device of the present invention, the tapered groove is located at the center of the fixed sleeve, and the number of the first chute is multiple, and the multiple groups of the first chute are distributed in a circular array along the axis of the fixed sleeve;

[0016] The slip ring includes a roller arranged on its inner wall, and the roller is adapted to the guide rail;

[0017] The protrusion is fixedly connected to the inner wall of the slip ring;

[0018] The guide rod passes through the fixing sleeve and extends to the outside of the fixing sleeve.

[0019] As a preferred solution of the electrocardiogram treatment vehicle with a wire management device of the present invention, wherein: the inner wall of the extrusion block is an inclined arc surface;

[0020] The extrusion block rotates synchronously with the slip ring, and the rotation of the extrusion block pushes the push rod to move toward the direction close to the tapered groove.

[0021] As a preferred solution of the electrocardiogram treatment vehicle with a cable management device of the present invention, wherein: the number of the balls is adapted to the first chute;

[0022] The pressing plate moves along its axis toward the first sliding groove, and the guide rod moves synchronously with the pressing plate, thereby driving the extrusion block to rotate with the slip ring to squeeze the push rod;

[0023] The push rod pushes the ball to move to the inner wall of the tapered groove, and at this time the outer wall of the ball is in close contact with the outer wall of the lead wire.

[0024] As a preferred solution of the electrocardiogram treatment vehicle with a wire management device of the present invention, the ball contacts the outer wall of the lead wire, and the ball moves in the same direction as the lead wire through friction.

[0027] A reset member is provided between the fixing sleeve and the pressing plate, and the reset member releases elastic potential energy, thereby causing the end of the screw cap to come into contact with the end surface of the fixing sleeve.

[0028] As a preferred solution of the electrocardiogram treatment vehicle with a cable management device of the present invention, the mobile unit is used to carry the electrocardiograph, and the winding unit is installed at the edge of the mobile unit;

[0029] There are multiple groups of winding units, and the multiple groups of winding units correspond to multiple groups of lead wires respectively.

[0030] The beneficial effects of the present invention are as follows: the present invention is configured to move the pressure plate toward the bottom surface of the positioning sleeve, thereby driving the push rod to squeeze the balls, so that the outer walls of multiple groups of balls are tightly against the outer walls of the lead wires to clamp and fix the lead wires. When the balls are tightly against the outer walls of the lead wires, the outer walls of the balls contact the inner walls of the tapered grooves. At this time, the staff can pull the lead wire outward to make the balls located at a position with a larger diameter of the tapered groove, and pulling the lead wire to move is more labor-saving. When the lead wire is stopped being pulled, the winding spring inside the winding unit drives the lead wire to contract, causing the balls to move to a position with a smaller diameter of the inner wall of the tapered groove, so that the balls contact the outer wall of the lead wire to fix the position of the lead wire.

DETAILED DESCRIPTION

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0043] Example 1

[0044] Reference Figures 1 to 3, which is the first embodiment of the present invention, provides an electrocardiogram treatment vehicle with a wire management device, which includes a winding unit 1, which is used to wind the lead wire; the winding unit 1 is composed of a shell, a winding roller arranged inside the shell, and a coil spring linked to the winding roller; the lead wire of the electrocardiograph is wound around the outside of the winding roller, and the coil spring releases elastic potential energy to wind the lead wire inside the shell.

[0045] The clamping unit 2 is provided at the open end of the winding unit 1 , and the lead wire can be fixed at a position outside the shell of the winding unit 1 through the clamping unit 2 , thereby ensuring the extended length of the lead wire.

[0046] The clamping unit 2 includes a fixing sleeve 21, which is a cylindrical structure, and the fixing sleeve 21 is centered to ensure that the lead wire can pass through the clamping unit 2; a pressure plate 22 is provided on the inner wall of the fixing sleeve 21, and a limit block is provided on the inner wall of the fixing sleeve 21. The limit block and the fixing sleeve 21 are connected by bolts. The limit block can effectively limit the movement trajectory of the pressure plate 22 to prevent the pressure plate 22 from detaching from the inner side of the fixing sleeve 21.

[0047] A first slide groove 211 and a tapered groove 212 are provided inside the fixed sleeve 21, and the first slide groove 211 and the tapered groove 212 are connected; a ball 23 is provided inside the first slide groove 211, and the ball 23 moves along the internal track of the first slide groove 211; a push rod 24 is provided inside the first slide groove 211, one end of the push rod 24 passes through the first slide groove 211 and extends to the outer wall of the fixed sleeve 21, and the other end contacts the ball 23, and the push rod 24 moves along the inner wall of the first slide groove 211 to push the ball 23 to move.

[0048] The outer wall of the fixed sleeve 21 is provided with a slip ring 25, which is coaxial with the fixed sleeve 21. The outer wall of the fixed sleeve 21 is provided with a guide rail, and the slip ring 25 rotates along the guide rail; the slip ring 25 is provided with an extrusion block 26 near the inner wall of the fixed sleeve 21. The extrusion block 26 and the slip ring 25 are connected and fixed by bolts, thereby ensuring that the extrusion block 26 can move synchronously with the slip ring 25, and the inner wall of the extrusion block 26 conflicts with the end of the push rod 24.

[0049] A protrusion 27 is provided inside the slip ring 25, and the protrusion 27 and the slip ring 25 are connected and fixed by bolts. A waist hole 271 is provided on the inner wall of the protrusion 27; a guide rod 28 is provided on the outer wall of the pressure plate 22; the slip ring 25 and the fixed sleeve 21 are linked to each other through the guide rod 28 and the waist hole 271. When the fixed sleeve 21 makes a linear motion in the vertical direction, the guide rod 28 is driven to slide in the waist hole 271, thereby forcing the slip ring 25 to rotate around its own axis.

[0050] During use, when the staff needs to control the length of the lead wire extended, they push the pressing plate 22 to move in the direction close to the fixing sleeve 21. During the movement of the pressing plate 22 along the axial direction of the fixing sleeve 21, the pressing plate 22 will approach the fixing sleeve 21 and hit the outer wall of the ball 23, pressing the ball 23 tightly into the inside of the first sliding groove 211; while the pressing plate 22 moves, it drives the guide rod 28 to squeeze the inner wall of the waist hole 271, so that the guide rod 28 slides along the inside of the waist hole 271, and while the guide rod 28 moves in the vertical direction, it drives the slip ring 25 to rotate, and the rotation of the slip ring 25 drives the extrusion block 26 to squeeze the push rod 24 to move, and the push rod 24 moves its end to push the ball 23 to move in the direction close to the tapered groove 212, thereby making the outer wall of the ball 23 hit the outer wall of the lead wire, thereby clamping and fixing the position of the lead wire.

[0051] Example 2

[0052] Reference Figures 1 to 7 , which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes a tapered groove 212 located at the center of the fixed sleeve 21, and the number of the first sliding grooves 211 is multiple, and the multiple groups of first sliding grooves 211 are distributed in a circular array along the axis direction of the fixed sleeve 21; the first sliding grooves 211 pass through the side wall of the fixed sleeve 21, and the push rod 24 is adapted to the first sliding grooves 211. The push rod 24 passes through the first sliding grooves 211 and extends to the outside thereof; the push rod 24 contacts the ball 23 at the end near the tapered groove 212.

[0053] In this embodiment, the opening diameter of the conical groove 212 gradually decreases along the direction from the pressure plate 22 to the fixed sleeve 21. The number of the first sliding grooves 211 is at least three groups, and the three groups of first sliding grooves 211 are all connected to the conical groove 212. The three groups of first sliding grooves 211 are distributed in a circular array along the axis of the conical groove 212.

[0054] The first slide groove 211 passes through the side wall of the fixed sleeve 21, thereby ensuring that the end of the push rod 24 can pass through the first slide groove 211 and extend to the outside of the fixed sleeve 21; one end of the push rod 24 passes through the outside of the fixed sleeve 21, and the other end contacts the ball 23, so that the staff can drive the push rod 24 to push the ball 23 toward the outer wall of the lead wire.

[0055] Furthermore, the pressure plate 22 is provided with a second slide groove 221 near the end surface of the first slide groove 211 . The pressure plate 22 is in contact with the end surface of the fixing sleeve 21 . The second slide groove 221 and the first slide groove 211 form a moving channel for the ball 23 .

[0056] In this embodiment, a second slide groove 221 is opened on the end surface of the pressure plate 22 corresponding to the fixed sleeve 21, and the position of the second slide groove 221 corresponds to the first slide groove 211. The inner wall of the second slide groove 221 contacts the outer wall of the ball 23, so that the outer wall of the ball 23 is tightly attached to the inner wall of the first slide groove 211.

[0057] Furthermore, the fixing sleeve 21 includes a guide rail 213 arranged on its outer wall, and the slip ring 25 includes a roller 251 arranged on its inner wall, and the roller 251 is adapted to the guide rail 213; the protrusion 27 is fixedly connected to the inner wall of the slip ring 25; the guide rod 28 passes through the fixing sleeve 21 and extends to its outside.

[0058] In this embodiment, a guide rail 213 is provided on the outer wall of the fixed sleeve 21, and the guide rail 213 and the fixed sleeve 21 are connected and fixed by bolts; a roller 251 adapted to the guide rail 213 is provided on the inner wall of the slip ring 25. When the slip ring 25 slides, the roller 251 moves along the track of the guide rail 213, thereby ensuring the sliding fit between the slip ring 25 and the guide rail 213.

[0059] It should be noted that a notch is provided in the fixing sleeve 21 at the position where the guide rod 28 moves vertically, and the guide rod 28 passes through the notch and extends to the outside of the fixing sleeve 21, and the end of the guide rod 28 extends to the inside of the waist hole 271; through the cooperation between the guide rod 28 and the waist hole 271, the pressure plate 22 can drive the guide rod 28 to move in the vertical direction, and the pressure plate 22 moves in the vertical direction and drives the slip ring 25 to rotate along its own axis.

[0060] Furthermore, the inner wall of the extrusion block 26 is an inclined arc surface; the extrusion block 26 rotates synchronously with the slip ring 25, and the extrusion block 26 rotates and then pushes the push rod 24 to move toward the direction close to the tapered groove 212.

[0061] In this embodiment, the inner wall where the extrusion block 26 contacts the push rod 24 is arc-shaped. As the slip ring 25 rotates, the inner wall of the extrusion block 26 continuously squeezes the end of the push rod 24, so that the push rod 24 can move different distances along the first slide groove 211; the movement of the push rod 24 can push the ball 23 to contact the outer wall of the lead wire.

[0062] Furthermore, the number of balls 23 is adapted to the first slide groove 211; the pressure plate 22 moves along its axis toward the first slide groove 211, and the guide rod 28 moves synchronously with the pressure plate 22, thereby driving the extrusion block 26 to rotate with the slip ring 25 to extrude the push rod 24; the push rod 24 pushes the balls 23 to move to the inner wall of the tapered groove 212, at which time the outer wall of the balls 23 is close to the outer wall of the lead wire.

[0063] It should be noted that the number of balls 23 is adapted to the first slide groove 211. When the pressure plate 22 moves along the axial direction of the fixed sleeve 21, the pressure plate 22 approaches the fixed sleeve 21 and drives the guide rod 28 to move. The guide rod 28 squeezes the inner wall of the waist hole 271 and then drives the slip ring 25 to rotate circumferentially around the axis of the fixed sleeve 21. While the slip ring 25 rotates, it drives the extrusion block 26 to squeeze the push rod 24, so that the push rod 24 pushes the ball 23 to move toward the outer wall of the lead wire.

[0064] Furthermore, the ball 23 contacts the outer wall of the lead wire, and the ball 23 moves in the same direction as the lead wire due to friction.

[0065] It should be noted that when the ball 23 contacts the lead wire, the corresponding position of the ball 23 is on the inner wall of the tapered groove 212; the ball 23 contacts the lead wire and, under the influence of friction, the ball 23 moves in the same direction as the lead wire.

[0066] Furthermore, a cover plate 31 is provided at the end of the fixing sleeve 21, and a screw cap 32 is provided inside the cover plate 31 to cooperate with its thread; a reset member 33 is provided between the fixing sleeve 21 and the pressure plate 22, and the reset member 33 releases elastic potential energy, thereby causing the end of the screw cap 32 to conflict with the end face of the fixing sleeve 21.

[0067] In this embodiment, in order to better control the distance between the pressure plate 22 and the fixing sleeve 21, the end of the fixing sleeve 21 is connected to the cover plate 31 by bolts, and the cover plate 31 is provided with an internal thread structure in the center position; the cover plate 31 and the screw cap 32 are threadedly matched, and by rotating the screw cap 32, the end of the screw cap can be made to contact the pressure plate 22 and push the pressure plate 22 to move toward the fixing sleeve 21.

[0068] When the end of the screw cap 32 is away from the end of the pressure plate 22, the reset member 33 releases elastic potential energy to push the pressure plate 22 toward the end of the screw cap 32, thereby moving the pressure plate 22 away from the ball 23.

[0069] When in use, when the staff needs to reel in the lead wire, they rotate the screw cap 32 so that the end of the screw cap 32 is away from the pressure plate 22. At this time, the reset member 33 releases the elastic potential energy to push the pressure plate 22 away from the fixing sleeve 21. The pressure plate 22 is away from the fixing sleeve 21 so that the inner wall of the second slide groove 221 no longer conflicts with the ball 23; the ball 23 has a large free movement space between the fixing sleeve 21 and the pressure plate 22, and the coil spring arranged inside the reeling unit 1 releases the elastic potential energy to drive the lead wire to be reeled in. During the reeling process, the ball 23 cannot limit the lead wire, and the lead wire is quickly reeled into the reeling unit 1.

[0070] When the lead wire needs to be stretched to a certain length, the screw cap 32 is rotated in the opposite direction to move the end of the screw cap 32 in the direction close to the pressure plate 22, and push the pressure plate 22 to contact the fixing sleeve 21 so that the inner wall of the second slide groove 221 conflicts with the outer wall of the ball 23; the pressure plate 22 and the fixing sleeve 21 cooperate to limit the vertical movement of the ball 23; during the downward movement of the pressure plate 22, the guide rod 28 is driven to move, and the guide rod 28 and the waist hole 271 cooperate to drive the slip ring 25 to rotate along the axis of the fixing sleeve 21, so that the slip ring 25 drives the extrusion block 26 to rotate, and the extrusion block 26 rotates its end to squeeze the push rod 24, so that the push rod 24 pushes the ball 23 to move along the inner wall of the first slide groove 211; as the pressure plate 22 conflicts with the end face of the fixing sleeve 21, the outer wall of the ball 23 conflicts with the outer wall of the lead wire, and the ball 23 is located inside the tapered groove 212; at this time, the staff can pull The movable lead wire extends outward, and at this time the ball 23 contacts the outer wall of the lead wire and does not form too much resistance. Only a certain force needs to be applied to pull the lead wire out; and when the staff pulls the lead wire to an appropriate length, the external force pulling the lead wire outward is released; at this time, the coil spring inside the winding unit 1 releases the elastic potential energy and has a force on the lead wire to contract, so that the lead wire has a tendency to be wound into the winding unit 1. When the lead wire contracts into the winding unit 1, it will drive the ball 23 to move synchronously with it, so that the ball 23 moves from the position with a larger opening diameter of the tapered groove 212 to the position with a smaller opening diameter. When the ball 23 moves in the direction of the smaller opening diameter of the tapered groove 212, it is squeezed by the inner wall of the tapered groove 212 and moves toward the direction close to the lead wire, further clamping the lead wire to the inner side of the ball 23, thereby fixing the position of the lead wire.

[0071] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
