Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a fixing device for an electrocardiogram lead wire. Background Art

[0002] In the current medical field, ECG acquisition is a common and critical diagnostic method, which is of great significance for the prevention and early detection of cardiovascular diseases. In the process of ECG acquisition, the use of lead wires is an indispensable link, which is responsible for connecting the ECG machine to various parts of the patient's body to collect the electrophysiological signals of the heart. However, the existing ECG lead wire fixing devices have many shortcomings in actual use and need to be improved. For example, ECG lead wires are usually long and soft, and are easy to entangle or knot with each other, which not only increases the difficulty of operation, but also prolongs the time of ECG acquisition. In addition, the entanglement of the lead wires may also cause interference in signal transmission, further affecting the quality of the ECG.

[0003] To solve the above problems, the patent with publication number CN213097933U proposes a lead wire fixing device for an electrocardiograph, comprising a fixing block, a slide groove is provided inside the fixing block, a slider is slidably connected inside the slide groove, one end of the slider is fixedly connected to a first baffle and a second baffle, the inner surfaces of the first baffle and the second baffle are fixedly connected to a telescopic rod, one end of the telescopic rod is fixedly connected to the surface of the fixing block; the utility model facilitates the separate insertion of the lead wires of the electrocardiograph by arranging a first fixing plate, a second fixing plate, a spring, a telescopic rod, a first baffle, a second baffle, a fixing block and a through hole, and at the same time, under the action of the spring and the telescopic rod, the through holes on the first fixing plate and the second fixing plate are moved to the left and right directions, thereby squeezing and fixing the lead wires, which not only avoids the mutual entanglement between the lead wires, but also improves the stability of the lead wires.

[0004] Although the above patent solves the problem of lead wires being entangled with each other, the fixing plate cooperates with the through-hole design to squeeze and fix the lead wires. If the spacing between adjacent lead wires is designed to be too large, this will make the fixing device longer and inconvenient to store. If the spacing is designed to be too small, it will be difficult to prevent the lead wires from being entangled. For this reason, the utility model provides a fixing device for electrocardiogram lead wires. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a fixing device for an electrocardiogram lead wire, which solves the problem that if the spacing between adjacent lead wires after fixing is designed to be too large, the fixing device will be too long and inconvenient to store; if the spacing is designed to be too small, it will be difficult to prevent the lead wires from being entangled.

[0006] To achieve the above purpose, the utility model is implemented by the following technical scheme: a fixing device for an electrocardiogram lead wire, comprising a frame, wherein a fixing mechanism is provided inside the frame, and the fixing mechanism comprises:

[0007] The wire clamping assembly is arranged inside the frame, and includes a fixed clamping block fixedly installed on the inner wall of the frame, and the inner wall of the frame is symmetrically and alternately installed with movable blocks, and the movable blocks include a lower clamping block and an upper clamping block slidably installed on the inner wall of the frame, and an inclined rod is fixed between the lower clamping block and the upper clamping block;

[0008] The elastic extrusion component is arranged on the inner wall of one side of the frame body and is used to perform a side extrusion effect on the clamping component;

[0009] The positioning component is arranged on the outer wall of one side of the frame body and is used for positioning the elastic extrusion component.

[0010] Preferably, the elastic extrusion assembly includes a sleeve fixedly connected to the inner wall of one side of the frame, a sliding column is slidably installed at one end of the sleeve, an extrusion plate is fixed at the end of the sliding column, a compression spring is sleeved on the outside of the sliding column, and one end of the compression spring is connected to the extrusion plate, and the other end is connected to the sleeve.

[0011] Preferably, the positioning assembly comprises a cross bar fixedly mounted on the extrusion plate, the end of the cross bar passes through the side wall of the frame and is connected to an I-shaped block, and a clamping rod is rotatably mounted on the I-shaped block.

[0012] Preferably, an opposing clamping seat is fixed on an outer wall of one side of the frame, and a clamping groove for the clamping rod to engage with is provided on the inner side of the opposing clamping seat.

[0013] Preferably, a first slider is fixed on the lower clamp block and the upper clamp block, a second slider is fixed on the upper and lower ends of the extrusion plate, and sliding grooves for directional sliding of the first slider and the second slider are provided on the upper and lower inner surfaces of the frame.

[0015] Beneficial Effects

[0016] The utility model provides a fixing device for electrocardiogram lead wires. Compared with the prior art, the utility model has the following beneficial effects:

[0017] (1) The fixing device for electrocardiogram lead wires passes the lead wires for electrocardiogram through the gaps between the fixing clamps and the adjacent movable blocks. Since the movable blocks are installed alternately and symmetrically, multiple groups of electrocardiogram lead wires are alternately staggered up and down, so that sufficient spacing can be left after the fixing is completed, effectively preventing the lead wires from being entangled with each other.

[0018] (2) The fixing device for the electrocardiogram lead wire pulls the clamping rod outward horizontally, and the cross bar drives the extrusion plate to be pulled outward horizontally, and the clamping rod is rotated to be clamped into the clamping groove on the opposite clamping seat. At this time, the compression spring is compressed and the clamping assembly is in a relaxed state. After the electrocardiogram lead wire is inserted, the clamping rod is rotated again to withdraw it from the clamping groove on the clamping seat. Under the reset action of the compression spring, the extrusion plate provides elastic pressure to the relaxed clamping assembly, so that the clamping assembly can fully clamp multiple sets of electrocardiogram lead wires.

[0027] The elastic extrusion component 22 is arranged on the inner wall of one side of the frame body 1 and is used to perform a side extrusion effect on the clamping component 21;

[0028] The positioning component 23 is disposed on an outer wall of one side of the frame body 1 and is used to position the elastic extrusion component 22 .

[0029] In this embodiment, the elastic extrusion assembly 22 includes a sleeve 221 fixedly connected to the inner wall of one side of the frame 1, a sliding column 222 is slidably installed at one end of the sleeve 221, an extrusion plate 224 is fixed at the end of the sliding column 222, a compression spring 223 is sleeved on the outside of the sliding column 222, and one end of the compression spring 223 is connected to the extrusion plate 224, and the other end is connected to the sleeve 221. Under the elastic extrusion action of the compression spring 223, the extrusion plate 224 provides elastic pressure to the relaxed wire clamping assembly 21, so that the wire clamping assembly 21 can fully clamp multiple sets of electrocardiogram lead wires.

[0030] In this embodiment, the positioning assembly 23 includes a cross bar 231 fixedly mounted on the extrusion plate 224, the end of the cross bar 231 passes through the side wall of the frame 1 and is connected to an I-shaped block 232, and a clamping rod 233 is rotatably mounted on the I-shaped block 232.

By pulling the clamping rod 233 horizontally outward, the extrusion plate 224 is pulled horizontally outward by the cross bar 231, and the clamping rod 233 is rotated and clamped into the clamping groove on the opposing clamping seat 234. At this time, the compression spring 223 is compressed, and the wire clamping assembly 21 is in a relaxed state.
