The shell 1 and the cover 12 are detachably connected, and the specific connection method can be a spiral buckle or a clamping buckle, and the column 2 is located at the center of the bottom of the inner wall of the shell 1 and can rotate axially, and the spring 3 is wound around the outer wall of the column 2, and one end is fixed to the column 2, and the other end is fixed to the inner wall of the shell 1, so that the column 2 can be reset by the action of the spring 3 after axial rotation, and the support rod 4 is slidably connected to the column 2, and the support rod 4 and the column 2 are simultaneously linked, that is, the rotation of the column 2 will drive the support rod 4 to rotate, and the support rod 4 can be set to a non-circular rod structure or an increased With the limit key added, the spring 5 gives the support rod 4 an upward force, so that the ratchet 8 is pressed against the cover body 12, that is, it is always meshed and connected with the pawl 9, and through the unidirectional drive of the ratchet 8 and the pawl 9, the winding disk can directly pull the two ends of the lead wire 11 when releasing the lead wire 11, and, when the winding disk is winding up the lead wire 11, the ratchet 8 and the pawl 9 can be separated, and it is realized by the spring 3. In this embodiment, the lead wire is a wiring harness on an electrocardiogram monitor, one end of which is a main line connector connected to the electrocardiogram monitor, and the other end is a plurality of branch line connectors connected to the electrode sheets on the patient.

Specifically, when in use, the cover 12 is first separated from the shell 1, and the midpoint of the lead wire 11 is fixed on the winding disk. At this time, the column 2 is rotated to make the lead wire 11 wind up on the winding disk. At this time, the spring 3 is in a contracted and force-storing state. When the joints on both sides are wound to fit the outer wall of the shell 1, the cover 12 is buckled into the top opening of the shell 1, and its support rod 4 is placed in the through hole 10. At this time, the pawl 9 and the ratchet 8 are in a meshing connection state. When the lead wire 11 needs to be extended, the joints on both sides can be pulled. Through the one-way driving function of the ratchet 8 and the pawl 9, the lead wire 11 can be extended by directly pulling the joints. The lead wire 11 can be extended and automatically locked and fixed during the extension process. When the lead wire 11 needs to be shortened, the support rod 4 can be pressed in the through hole 10 to overcome the elastic force of the spring 5 and slide in the direction of the column 2, so that the ratchet 8 is separated from the pawl 9. At this time, the column 2 exerts its limiting force, and with the release of the spring 3, the lead wire can be wound around the winding reel again, so that the lead wire can be adjusted to its usage length according to usage requirements, avoiding the excessively long part from being easily wound around the patient when used at the bedside, affecting the patient's comfort, and eliminating the occurrence of mopping on the floor, avoiding cross infection, having practicality, and being suitable for popularization and use.

As an optional embodiment, the winding reel includes a reel body 6 and a plurality of slots 7. The reel body 6 is disposed on the column 2. The plurality of slots 7 are processed on the edge of the reel body 6. The plurality of slots 7 are used to pass the lead wires 11 so that the lead wires 11 can be wound around the reel body 6 when the reel body 6 rotates.

Specifically, the lead wire 11 can be fixed by passing the lead wire 11 through two slots of the plurality of slots 7 in sequence.

As an optional embodiment, a clip 13 is provided on a side of the housing 1 facing away from the cover 12 .

Specifically, by providing the clamp 13, the device can be fixed on the patient, thereby avoiding the risk of the electrode being pulled off the patient due to excessive weight of the lead wire due to excessive body movement, thereby ensuring the stability of ECG monitoring.

As an optional implementation, the limiting direction of the ratchet 8 and the pawl 9 is the direction in which the lead wire 11 is wound around the take-up reel, and the releasing direction is the direction in which the lead wire 11 is separated from the take-up reel.

Specifically, by setting the ratchet 8 and the pawl 9, the lead wire 11 can be released by directly pulling and can be automatically locked, while when it is rolled up, it only needs to press the support rod 4.

As an optional implementation, the side of the support rod 4 placed in the inner cavity of the column 2 is a square rod-shaped structure, and the side placed in the through hole 10 is a round rod-shaped structure.

Specifically, the square rod-shaped structure enables the support rod 4 to rotate along with the pillar 2 , while the round rod-shaped structure prevents the support rod 4 from interfering with the through hole 10 during rotation.

By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

The working process and working principle of the utility model are as follows: when in use, the cover body 12 is first separated from the shell 1, and the midpoint of the lead wire 11 is fixed on the winding disk. At this time, the column 2 is rotated to make the lead wire 11 wind up on the winding disk. At this time, the spring 3 is in a contracted and force-storing state. When the joints on both sides are wound to fit the outer wall of the shell 1, the cover body 12 is buckled on the top opening of the shell 1, and its support rod 4 is placed in the through hole 10. At this time, the pawl 9 and the ratchet 8 are in a meshing connection state. When the lead wire 11 needs to be extended, the joints on both sides can be pulled. Through the one-way driving function of the ratchet 8 and the pawl 9, the joints can be directly pulled. The lead wire 11 is extended, and can be automatically locked and fixed during the extension process. When the lead wire 11 needs to be shortened, the support rod 4 in the through hole 10 can be pressed to overcome the elastic force of the spring 5 and slide in the direction of the column 2, so that the ratchet 8 and the pawl 9 are separated. At this time, the column 2 exerts its limiting force, and with the release of the spring 3, the lead wire can be wound around the winding reel again, so that the lead wire can be adjusted to its usage length according to usage requirements, avoiding the excessively long part from being easily wrapped around the patient when used at the bedside, affecting the patient's comfort, and eliminating the occurrence of mopping on the floor, avoiding cross infection, having practicality, and being suitable for popularization and use.
