Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a retractable and retractable electrocardiograph lead cable. Background Technology

[0002] Chinese patent document CN216004817U discloses an automatic retractable and retractable electrocardiograph lead wire storage device, including a main unit connector, a junction box, a main wire, and branch wires. The main unit connector is fixedly connected to the main wire, and the branch wires are connected to the main wire through the junction box. Each branch wire has an electrode plate at its end, and each branch wire has a storage part in the middle. The lead wire can be stored in the storage part in the middle of the branch wire. When in use, the lead wire is pulled out to the required length and then locked by a limiting rotation device. After use, the rotating rod is moved in the groove, the ratchet disengages from the ratchet wheel, and the lead wire is automatically retracted into the device.

[0003] However, the aforementioned devices have independently configured wiring, which can easily cross and tangle during use, making it difficult to manage. To address this, we propose a retractable and foldable electrocardiograph lead cable. Utility Model Content

[0004] The purpose of this invention is to provide a retractable and retractable electrocardiograph lead wire that can solve the problem of easy cross-entanglement of the wires in some existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a retractable and retractable electrocardiograph lead cable, comprising:

[0006] The junction box has at least two sets of guide wires fixedly connected to its front side. A take-up roller is provided on the front side of the junction box. The take-up roller is movably sleeved on each guide wire. A set of limit plates is fixedly installed at both ends of the take-up roller. A set of slots is opened on each of the two sets of limit plates.

[0007] The fixing mechanism is installed on the junction box and is used to fix the winding roller after winding.

[0008] The positioning mechanism is set on the take-up roller and the limiting plate. The positioning mechanism includes a threaded rod and a stop block. A threaded rod is threadedly installed on one side of the outer surface of a set of limiting plates. One end of the threaded rod extends into the take-up roller and is rotatably installed with the stop block.

[0009] Preferably, the positioning mechanism further includes a knob. The other end of the threaded rod is fixedly installed on the outside of the limiting plate. With the cooperation of the take-up roller and the positioning mechanism, when the various lead wires are tangled and messy during use, the positioning mechanism is unlocked and the take-up roller is slid to quickly sort out the various lead wires. This solves the problem that the lead wires in some existing devices are set up independently and are easy to cross and entangle with each other during use, which makes sorting difficult and improves the practicality of the lead wires.

[0010] Preferably, the fixing mechanism includes binding strips, hook and loop fasteners, and hook and loop fasteners. Two sets of binding strips are fixedly connected to the top of the junction box, and both sets of binding strips can be wound around corresponding slots. One end of each set of binding strips is fixedly installed with a set of hook and loop fasteners. Two sets of hook and loop fasteners are fixedly installed at the bottom of the junction box, and the two sets of hook and loop fasteners are pasted onto the corresponding hook and loop fasteners. With the cooperation of the limiting plate and the fixing mechanism, after the lead wires are untangled, each lead wire can be wound up onto the take-up roller and fixed, achieving quick storage, reducing space occupation, ensuring the effectiveness of the lead wires, and facilitating the promotion and use of lead wires.

[0011] Preferably, a handle is fixedly installed on one outer surface of each of the two sets of limiting discs.

[0012] Preferably, one end of each set of lead wires is fixedly equipped with a set of electrode plates.

[0013] Preferably, a main lead wire is fixedly connected to the rear outer surface of the junction box, and a connector is fixedly connected to one end of the main lead wire.

[0014] Preferably, an anti-slip pad is fixedly installed on one outer surface of the abutment block, and the abutment block abuts against the corresponding lead wire through the anti-slip pad, which can further improve the relative fixation between the abutment block and the lead wire.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The retractable electrocardiograph lead cable, through the cooperation of the winding roller and the positioning mechanism, can quickly sort out the lead cables when the various lead cables are messy due to crossover during use by unlocking the positioning mechanism and sliding the winding roller. This solves the problem that the lead cables of some existing devices are set up independently and are easy to cross and entangle during use, which makes sorting difficult and improves the practicality of the lead cable.

[0017] (2) The retractable electrocardiograph lead wire, through the cooperation of the limiting plate and the fixing mechanism, can roll up each lead wire onto the winding roller and fix it after the lead wire is unpacked, so as to achieve quick storage, reduce space occupation, ensure the use effect of the lead wire, and facilitate the promotion and use of the lead wire.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a retractable and retractable electrocardiograph lead wire, including a wire distribution box 1, a fixing mechanism 7 and a positioning mechanism 6. At least two sets of lead wires 2 are fixedly connected to the front side of the wire distribution box 1. A winding roller 3 is provided on the front side of the wire distribution box 1. The winding roller 3 is movably sleeved on each lead wire 2. A set of limiting discs 4 are fixedly installed at both ends of the winding roller 3. A set of slots 5 are opened on both sets of limiting discs 4. The fixing mechanism 7 is provided on the wire distribution box 1. The fixing mechanism 7 is used to fix the winding roller 3 after winding. A set of handles 8 are fixedly installed on one side of the outer surface of each set of limiting discs 4. A set of electrode plates 9 are fixedly installed at one end of each set of lead wires 2. A lead main wire 10 is fixedly connected to the rear outer surface of the wire distribution box 1. A connector 11 is fixedly connected to one end of the lead main wire 10.

[0026] The positioning mechanism 6 is set on the take-up roller 3 and the limiting plate 4. The positioning mechanism 6 includes a threaded rod 61 and a stop block 62. The threaded rod 61 is threaded on one side of the outer surface of a set of limiting plates 4. One end of the threaded rod 61 extends into the take-up roller 3 and is rotatably mounted with the stop block 62.

[0027] The positioning mechanism 6 also includes a knob 63. The other end of the threaded rod 61 is fixedly installed with a knob 63 on the outside of the limiting plate 4. An anti-slip pad 12 is fixedly installed on one side of the outer surface of the abutment block 62. The abutment block 62 abuts against the corresponding guide branch line 2 through the anti-slip pad 12. With the cooperation of the winding roller 3 and the positioning mechanism 6, when the various guide branch lines 2 are crossed and messy during use, the positioning mechanism 6 is unlocked and the winding roller 3 slides to quickly sort out the various guide branch lines 2. This solves the problem that the branch lines of some existing devices are set independently and are easy to cross and entangle with each other during use, which makes sorting difficult and improves the practicality of the guide lines.

[0028] The fixing mechanism 7 includes binding strips 71, hook and loop fasteners 72, and hook and loop fasteners 73. Two sets of binding strips 71 are fixedly connected to the top of the junction box 1. Both sets of binding strips 71 can be wound around the corresponding slots 5. A set of hook and loop fasteners 72 is fixedly installed at one end of each set of binding strips 71. Two sets of hook and loop fasteners 73 are fixedly installed at the bottom of the junction box 1. The two sets of hook and loop fasteners 72 are pasted onto the corresponding hook and loop fasteners 73. Through the cooperation of the limiting plate 4 and the fixing mechanism 7, after the lead wires are combed out, each lead wire 2 can be wound up onto the take-up roller 3 and fixed, realizing quick storage, reducing space occupation, ensuring the use effect of the lead wires, and facilitating the promotion and use of lead wires.

[0029] Working principle: During normal use, the threaded rod 61 will be tightened, causing the stop block 62 to abut against the corresponding guide branch line 2 to prevent the take-up roller 3 from sliding. When the guide branch lines 2 become tangled after use, turn the knob 63 to drive the threaded rod 61 out, causing the stop block 62 to no longer abut against the corresponding guide branch line 2, and then disengage the two sets of limiting discs 4 from the binding strips 71. The take-up roller 3 can then slide to comb out the guide branch lines 2. When the take-up roller 3 reaches the end of each guide branch line 2, turn the take-up roller 3 again to wind up each guide branch line 2 until it is finished. Then, wrap the two sets of binding strips 71 around the two sets of limiting discs 4, and stick the two sets of hook and loop fasteners 72 onto the hook and loop fasteners 73 for fixation.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
