Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an anti-winding wire harness. Background Art

[0002] Electrocardiographs are often used to detect the physiological functions of the human heart. Electrodes are placed on different parts of the human body and connected to the positive and negative poles of the electrocardiograph's ammeter through lead wires. The electrocardiogram waveform is detected to reflect the condition of the human heart. This circuit connection method for recording electrocardiograms is called an electrocardiogram lead. Since there are many lead wires connected to the electrocardiograph, they are prone to knotting and entanglement, which causes medical staff to spend a lot of time to organize them, making them inconvenient to use. Related technologies usually set protective covers or wire clamps on the lead wires to analyze and organize multiple strands of lead wires. However, whether it is a protective cover or a wire clamp, it can only act on one point on the lead wire, and the rest of the lead wire is soft. The lead wires will still be intertwined and entangled with each other, and the anti-entanglement effect is not obvious. Utility Model Content

[0003] The technical purpose of the utility model is to provide an anti-entanglement wire harness, aiming to solve the problem that lead wires are prone to entanglement in the related technology.

[0004] To solve the above technical problems, the utility model is implemented as follows: an anti-tangle harness, comprising: an injection-molded anti-tangle piece, a junction box and at least two cables; at least two cables respectively pass through the junction box and are fixedly connected to the junction box, each cable is respectively divided into a first end and a second end by the junction box, the outer sides of at least the two first ends are surrounded by the anti-tangle piece and combined with the anti-tangle piece as a whole, and the second ends are separated from each other.

[0005] Furthermore, the first ends integrated with the same anti-entanglement element are arranged side by side.

[0006] Furthermore, the cables are divided into chest lead wires and limb lead wires, the number of chest lead wires is six, and the number of limb lead wires is four; the chest lead wires and the limb lead wires are respectively surrounded and fixed by different anti-entanglement parts, and the chest lead wires and the limb lead wires are respectively connected to different junction boxes.

[0007] Furthermore, the anti-entanglement piece is a three-cavity anti-entanglement piece, which divides the chest lead wire into two first wire bundles of three wires, and one first wire bundle is connected to a junction box.

[0008] Furthermore, the anti-entanglement piece is a two-cavity anti-entanglement piece, which divides the limb lead wire into two second wire bundles, and one second wire bundle is connected to a junction box.

[0009] Furthermore, the material of the anti-entanglement piece is rubber.

[0010] Furthermore, the anti-tangle harness also includes a main cable and an adapter; one end of the adapter is connected to the main cable, and the other end is connected to the anti-tangle piece.

[0011] Furthermore, a plug is provided at one end of the main cable away from the adapter.

[0012] Furthermore, the junction box has a shape of a polygon, a circle, or an ellipse.

[0013] Compared with the prior art, the anti-entanglement harness in the utility model has the following beneficial effects: the one end of each cable is combined into one by injection molding, and then a junction box is used at the other end of the cable to separate each cable into a single wire, so that each cable can collect physiological signals from different parts of the human body. Such a setting can effectively avoid the situation where many long cables are entangled with each other. In addition, the use of a junction box can further reduce the probability of cable entanglement, and can also reduce the risk of damage to the anti-entanglement device or cable when the staff pulls the cable improperly.

[0019] Example:

[0020] like Figure 1 As shown, in this embodiment, the anti-tangle harness includes: an injection-molded anti-tangle piece 1, a junction box 2 and at least two cables 3; at least two cables 3 pass through the junction box 2 and are fixedly connected to the junction box 2, each cable 3 is divided into a first end (not shown in the figure) and a second end by the junction box 2, at least the outer sides of the two first ends are surrounded by the anti-tangle piece 1 and combined with the anti-tangle piece 1 as a whole, and the second ends are separated from each other.

[0021] Specifically, the first end of the cable 3 is fixed by the anti-entanglement piece, and the second end is not fixed by the anti-entanglement piece. The length of the first end can be longer than the second end, and the ratio of the length of the first end to the length of the second end can be 3:1 or 4:1, 5:1, etc., which is not limited here. The anti-entanglement piece 1 in this embodiment can be an injection-molded plastic part, which can be obtained by pre-embedded cable 3 in a preset mold and then injection-molded and encapsulated, and the fixing effect between the plastic part and the cable 3 is good. The injection molding processing method is used to combine one end of each cable 3 into one, and then the junction box 2 is used at the other end of the cable 3 to divide each cable 3 into a single wire, so that each cable 3 can collect physiological signals from different parts of the human body respectively. Such a setting can effectively avoid the situation where the cables 3 are entangled with each other due to multiple and long cables 3. The use of the junction box 2 can further reduce the probability of cable 3 being entangled, and can also reduce the risk of damage to the anti-entanglement piece 1 or cable 3 when the staff operates improperly (when pulling the cable 3 in different directions).

[0022] In this embodiment, the first ends integrated with the same anti-entanglement piece 1 are arranged side by side. That is, multiple cables 3 are injection molded into an integrated parallel line, which solves the entanglement problem while ensuring the integrity and aesthetics of the lead wire harness. It is understandable that in some other embodiments, the cables 3 fixed by the same anti-entanglement piece 1 can also be arranged in other ways. For example, when there are three, four or more cables 3, the cables 3 can be arranged in three dimensions, that is, the projection points of the cables in the radial direction can be connected to form a triangle, quadrilateral, pentagon, etc., which is not limited here.

[0023] In the present embodiment, the shape of the junction box 2 is one of a polygon, a circle, and an ellipse. It is understandable that the shape of the junction box 2 may refer to the projection shape of the junction box 2. The shape of the junction box 2 may also be a rounded quadrilateral or even an irregular shape, etc., which is not limited here. It should be noted that the junction box 2 in the present embodiment may be a detachable junction box, or a junction box integrally formed with the anti-entanglement member 1. The junction box 2 may also be a movable junction box, that is, one end of the junction box 2 is set to be open or an inlet is provided for the cable 3 to pass through, and then a plurality of spaced lead-out holes are provided on the remaining part or all of the sides of the junction box 2 for each cable 3 to pass through separately, so that the junction box 2 can be moved to the ideal position in the second end as needed. Of course, in some embodiments, an elastic adjustment component may also be provided on the movable junction box 2 so that the junction box 2 is firmly connected to the cable 3 when it does not need to be moved, and the moving operation is smoother when moving.

[0024] In this embodiment, the cable 3 is divided into chest lead wires 31 and limb lead wires 32, the number of chest lead wires 31 is six, and the number of limb lead wires 32 is four; the chest lead wires 31 and the limb lead wires 32 are respectively surrounded and fixed by different anti-entanglement parts 1, and the chest lead wires 31 and the limb lead wires 32 are respectively connected to different junction boxes 2.

[0025] Specifically, the configured electrocardiograph may be an electrocardiograph having two rows of 15-pin connectors at one end and 10 lead wires at the other end. The 10 lead wires include 6 chest lead wires 31 and 4 limb lead wires 32, which are used to collect electrocardiograph signals at different positions of the human body and transmit them to the electrocardiograph body through the connector, thereby measuring the 12-lead electrocardiograph waveform of the human body. In this embodiment, according to the different types of lead wires, the anti-entanglement piece 1 and the junction box 2 are used to respectively set the multiple cables 3 into branching bundles with different functions, which can not only achieve a good anti-entanglement effect, but also help to improve the work efficiency of the staff.

[0026] Further, in the present embodiment, the anti-entanglement member 1 may be a three-chamber anti-entanglement member, which divides the chest lead wire 31 into two first wire bundles of three wires, and one first wire bundle is connected to a junction box 2. That is, the anti-entanglement member 1 and the junction box 2 are used to fix every three chest lead wires 31 into a bundle, which can not only achieve a good anti-entanglement effect, but also help improve the work efficiency of the staff. It can be understood that in some other embodiments, the first ends of the six chest lead wires 31 can also be fixed as a whole with the same anti-entanglement member 1, which is not limited here. The anti-entanglement member 1 may be a two-chamber anti-entanglement member, which divides the limb lead wire 32 into two second wire bundles of two wires, and one second wire bundle is connected to a junction box 2. That is, the anti-entanglement member 1 and the junction box 2 are used to fix the limb lead wires 32 into a bundle in pairs, so as to facilitate the connection of each limb lead wire 32 to the corresponding position of the human body. In this embodiment, the first end of each cable 3 is organized into four wire harnesses by the anti-entanglement piece 1 according to the type of the cable 3, and then the cable 3 in the wire harness is divided into single wires by the junction box 2 at the end of the wire harness close to the human body, thereby reducing the number of wire harnesses and effectively solving the problem of easy entanglement between lead wires. The material of the anti-entanglement piece 1 can be rubber, specifically TPU, PCV, etc., with low raw material cost and processing cost, and the connection between the injection-molded anti-entanglement piece 1 and the cable 3 is stable.

[0027] In this embodiment, the anti-entanglement harness also includes a main cable 4 and an adapter 5, one end of the adapter 5 is connected to the main cable 4, and the other end is connected to the anti-entanglement part 3. That is, the adapter 5 electrically connects each chest lead wire 31, each limb lead wire 32, and the main cable 4 into one. The adapter 5 can realize signal shunting, thereby ensuring smooth signal transmission between the main cable 4 and each chest lead wire 31, and between the main cable 4 and each limb lead wire 32. A plug 6 is also provided at one end of the main cable 4 away from the adapter 5. The plug 6 can be connected to the corresponding connector of the electrocardiograph, so that the electrocardiograph signals collected by each cable 3 can be transmitted back to the electrocardiograph.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
