The specific meanings of the above terms in the present invention can be understood in a specific case to those of ordinary skill in the art.

The invention discloses a coiling device of a lead wire for electrocardiograph monitoring, which aims to solve the problem that the coiling device needs frequent manual locking in the prior art, and the following embodiment of the invention is specifically explained.

As shown in fig. 1 to 9, the coiling device of the lead wire for electrocardiographic monitoring of the present embodiment includes a housing 1; the housing 1 is provided with a plurality of (4 in this embodiment), one housing 1 corresponds to one branch line 262 (the main line 261 of the lead line 26 in this embodiment is short and does not need to be accommodated, therefore, in this embodiment, the main line 261 is not accommodated), and the housings (referred to as 4 housings) can be assembled and disassembled, which is set because the fixing problem of the housing 1 is considered: generally, fixing the case 1 at a certain position can prevent the case 1 from falling off and being involved in the parting line and the human body joint, and the case 1 can be directly assembled by a common fixing method such as a double-sided tape and a suction cup (the fixing device is not shown).

Each of the housings 1 of the present embodiment is provided with a disc 2 and a coil spring 3 (as shown in fig. 4, the bottom of the disc 2 of the present embodiment is rotatably disposed on the housing 1, the coil spring 3 is sleeved on the bottom of the disc 2, and the inner end (i.e., end e in fig. 4) of the coil spring 3 is fixed to the bottom of the disc 2, the outer end (i.e., end f in fig. 4) of the coil spring 3 is fixed to the housing 1), the middle of the disc 2 is sleeved with a coil structure 4, the coil structure 4 of the present embodiment is divided into two parallel grooves (specifically, an upper groove is disposed between A1 and A3 in fig. 2, and a lower groove is disposed between A2 and A4), the two grooves are connected to each other by a spiral groove, the middle of the branching line 262 is clamped in the middle, and then the two ends are spirally wound in the upper groove and the lower groove respectively (the winding principle is similar to the arrangement of a flexible data line in the prior art), and thus, the two sides can both can be pulled, and further prevent the housing 1 of the coil apparatus from being pulled and separated from the original fixed position.

When the wire coiled by the wheel disc 2 is driven to stretch by external force, the wheel disc 2 is forced to rotate in the shell 1 and tighten the coil spring 3, so that when the coiled wire is unfolded outwards under the action of human, the coil spring 3 is tightened, and once the human action is lost, the coil spring 3 automatically withdraws the uncoiled wire so as to avoid manual coiling.

The wheel disc 2 in the implementation is provided with the ratchet wheel 5, the shell 1 is movably provided with the pawl 6 used for being matched with the ratchet wheel 5, and the ratchet wheel mechanism formed by the ratchet wheel mechanism and the ratchet wheel can lock the opposite direction of rotation of the wheel disc 2 during coiling, so that when the wheel disc 2 rotates, the ratchet wheel 5 can also rotate synchronously, and the characteristic of the ratchet wheel mechanism is that an object connected with the ratchet wheel 5 can only rotate in a single direction.

Therefore, when the wheel disc 2 rotates towards the line-spreading direction, the ratchet wheel 5 allows the rotation direction, and when the wheel disc 2 rotates towards the line-winding direction, the ratchet wheel 5 does not allow the rotation direction; it can be seen that the user can pull out the branch line 262 by hand freely, and once the hand is stopped, the ratchet mechanism is self-locked, the wheel disc 2 is locked, and the length of the branch line 262 is fixed.

Moreover, the introduction of a ratchet mechanism has another advantage: after the lead wire 26 is connected to the human body, the branch wire 262 is generally locked by the lead wire storage device in the prior art after the branch wire is pulled out, and once medical staff or patients or other staff (such as family members of the patients) pull the lead wire 26 accidentally, discomfort of the human body can be caused or the lead wire storage device in the prior art is driven by the lead wire 26 to be separated from the human body; however, the coiling device of the present invention still allows the branch wire 262 to be pulled out after the lead wire 26 is connected to the human body, thereby solving the problem at the root.

Then, two ends of the branching line 262 (in fig. 2, C1 and C2 are respectively marked on the two ends of the branching line 262 to distinguish the left end and the right end), the end C1 passes through the lower groove and then just enters the end A4, and the end C2 passes through the lower groove and then just enters the end A1.

In order to further improve the function of preventing the wire separating 262 from pulling the housing 1 of the coiling device of the present invention, preferably, at least two wire placing cavities 7 (four wire placing cavities 7 in this embodiment, which are distributed symmetrically left and right, specifically, A1, A2, A3, and A4 in fig. 2) are formed in the housing 1 of this embodiment, so as to respectively nest two ends of the wire coiled by the wheel disc 2; the two sides of the inner wall of the wire placing cavity 7 are alternately and movably provided with a guide piece so as to form a snake-shaped channel 10 for the wire coiled by the wheel disc 2 to pass through.

Along the axis direction of putting line cavity 7, the guide distributes in the both sides of axis, and the guide can carry out the swing of certain degree, and general amplitude of oscillation is 60 degrees.

As shown in fig. 8, when the angle formed by the guiding element and the central axis is the largest, the length of the serpentine channel 10 is the longest, and when the branch line 262 enters the serpentine channel 10, the length of the branch line 262 that can be temporarily stored is the longest.

As shown in fig. 9, the serpentine channel 10 has the shortest length when the guide forms the smallest angle with the central axis, and the branch 262 only needs a shorter length to pass through the serpentine channel 10.

According to the working principle of the guide piece, a large included angle is formed between the guide piece and the central axis and is a normal state, so that the long wire distributing part 262 can be stored in the wire arranging cavity 7, when the wire distributing part 262 is pulled suddenly by external force, the guide piece is controlled to be switched to a state of forming a small included angle with the central axis, the long wire distributing part 262 stored in the wire arranging cavity 7 can slide out to buffer, and the human body discomfort is prevented from being caused or the coiling device is prevented from being pulled to be separated from the human body.

In order to realize the automatic control of the guiding element, preferably, the guiding element of the present embodiment is configured as a rod-shaped structure 8, the rod-shaped structure 8 is provided with a pulley 9 in rotation with the one end that the separated time 262 contacts, the other end of the rod-shaped structure 8 and the inner wall of the wire placing cavity 7 are provided with an inclined plane 11 that fits each other, the inclined plane 11 is in a direction towards the wheel disc 2, one end of the inclined plane 11 that is close to the inner wall of the wire placing cavity 7 is provided with a rotating structure 12 to connect the rod-shaped structure 8 and the inner wall of the wire placing cavity 7, and one side of the rod-shaped structure 8 that is close to the rotating structure 12 is connected with the inner wall of the wire placing cavity 7 through an elastic structure 13.

By the action of the inclined plane 11, the rod-shaped structure 8 cannot rotate towards the center of the device, and the elastic coefficient of the elastic structure 13 is smaller than that of the elastic system of the coil spring 3, taking fig. 8 as an example, when the branch line 262 (actually, the branch line of the lead line 26) in the left-side drawing diagram, the branch line 262 forms an inclined but approximately leftward force on the rod-shaped structure 8 to drive the rod-shaped structure 8 to rotate leftward, and the elastic structure 13 is compressed, so that part of the branch line 262 can be rapidly extended, and when the external force disappears, the rod-shaped structure 8 is reset under the action of the elastic structure 13.

However, when the coil spring 3 winds the branch wire 262, the position of the rod-shaped structure 8 is not affected by the presence of the inclined surface 11.

The inner wall of the shell 1 protrudes inwards to form a mounting part 14, the other end of the wheel disc 2 is rotatably arranged on the mounting part 14, a mounting plane 15 is formed on the outer side, close to the mounting part 14, of the wire coiling structure 4, the ratchet wheel 5 is fixed on the mounting plane 15, and the center of the ratchet wheel 5 is located on a rotating shaft of the wheel disc 2.
