Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an elastic shock-absorbing and interference-reducing waist belt for treadmill electrocardiogram lead wires. Background Technology

[0002] The treadmill exercise test is an important non-invasive clinical examination used to diagnose coronary heart disease, assess cardiovascular function, and evaluate exercise tolerance. It involves having patients perform graded exercises on a treadmill while simultaneously and continuously acquiring electrocardiogram (ECG) signals to observe changes in heart rate, ST segment, and other indicators. This provides objective evidence for the screening, diagnosis, and evaluation of treatment outcomes for cardiovascular diseases. This test must be performed while the patient is in a continuous exercise state, and it places strict requirements on the continuity, stability, and accuracy of ECG signal acquisition. Reliable fixation of the lead electrodes is a core condition for ensuring the successful conduct of the test and the accuracy and validity of the data.

[0003] Currently, the standard bandages used for fixing ECG leads in treadmill stress tests have significant technical shortcomings and fail to meet the examination requirements. Firstly, the fixation is not secure enough; the bandages lack elasticity and proper fit, making them prone to loosening and displacement during patient movement, leading to poor electrode contact and affecting signal acquisition. Secondly, adjustment is inconvenient; most are simple clips or adhesive structures, unable to quickly and accurately adjust tightness according to different body types, resulting in a poor user experience. Thirdly, anti-interference performance is poor; they lack anti-static and electromagnetic shielding designs, allowing static electricity generated by clothing friction during movement and environmental electromagnetic interference to directly affect ECG signals, causing baseline drift, increased noise, and reducing the reliability and diagnostic value of the test data.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1:

[0021] Please see Figures 1-8 The present invention provides an elastic shock-absorbing and interference-reducing waist belt for treadmill electrocardiogram lead wires, comprising: a composite waist belt body 1, which is made of high elastic nylon fabric as the main substrate, and is sequentially composited with a bamboo fiber skin-friendly layer 11, a copper fiber electromagnetic shielding layer 12 and a wear-resistant polyester fiber layer 13 from the inside to the outside. A continuous conductive fiber strip 14 is provided on the inner side of the bamboo fiber skin-friendly layer 11 along the length direction of the bottom edge. An antistatic agent is added to the bamboo fiber skin-friendly layer 11 and the wear-resistant polyester fiber layer 13. The lead fixing component 2 includes a rectangular sliding sleeve 21, a pin 22 is rotatably connected inside the rectangular sliding sleeve 21, a micro screw 23 is threaded to the bottom end of the pin 22, a toothed plate 24 is fixedly connected to the outer wall of the pin 22, and a lever 25 is fixedly connected to the top end of the pin 22. A slot 26 is fixedly connected to the back of the rectangular sliding sleeve 21, and a straight groove 27 is opened on the outer surface of the rectangular sliding sleeve 21. An elastic pressure plate 28 is integrally connected to the inner wall of the straight groove 27. The belt buckle 3 includes a rectangular sleeve 31, a rectangular through groove 32 through the top of the rectangular sleeve 31, two pressing blocks 33 slidably connected inside the rectangular through groove 32, a locking block 34 fixedly connected to the outer wall of the pressing block 33, and a receiving groove 35 inside the pressing block 33, in which a serpentine spring sheet 36 is placed. Slots 37 through the sides of the rectangular sleeve 31 are provided, and buckle plates 38 are slidably connected inside the slots 37. An assembly groove 39 is provided on the back of the rectangular sleeve 31. A groove 310 is provided on the outer surface of the buckle plate 38, and two sets of limiting grooves 311 are provided on the outer surface of the buckle plate 38.

[0022] Furthermore, the bamboo fiber skin-friendly layer 11 has a thickness of 0.2mm-0.4mm, the copper fiber electromagnetic shielding layer 12 has a thickness of 0.1mm-0.3mm, the wear-resistant polyester fiber layer 13 has a thickness of 0.3mm-0.5mm, and the bamboo fiber skin-friendly layer 11 has multiple micron-level air pores uniformly opened inside, which are arranged to run through the thickness direction and communicate with the outside air.

[0023] The thickness of the bamboo fiber skin-friendly layer 11 is set to 0.2mm-0.4mm, the thickness of the copper fiber electromagnetic shielding layer 12 is set to 0.1mm-0.3mm, and the thickness of the wear-resistant polyester fiber layer 13 is set to 0.3mm-0.5mm. This makes the composite waist belt body 1 lightweight, soft, and fits the human body, while ensuring a balance between skin-friendly, shielding, and wear-resistant properties. At the same time, micron-level breathable pores are evenly opened inside the bamboo fiber skin-friendly layer 11, which run through the thickness direction and are connected to the outside air. This can significantly improve the breathability and moisture-wicking capacity of the waist belt, avoid the problem of stuffiness and sweating when patients wear it for a long time, improve wearing comfort, and reduce poor electrode contact caused by sweat accumulation, thus ensuring stable ECG signal acquisition.

[0024] Furthermore, the bamboo fiber skin-friendly layer 11 is made of bamboo fiber and spandex blended and woven, and its inner surface is treated with brushing and softening. The wear-resistant polyester fiber layer 13 is made of high-strength low-elongation polyester fiber double warp and double weft weaving. The bamboo fiber skin-friendly layer 11, copper fiber electromagnetic shielding layer 12 and wear-resistant polyester fiber layer 13 are all connected with a high-elasticity nylon substrate through warp and weft.

[0025] The bamboo fiber skin-friendly layer 11 is made of bamboo fiber and spandex blend and woven together, with the inner surface treated with a brushed and softened finish. This enhances the skin-friendly feel and softness during wear, as well as improves fit and comfort. The wear-resistant polyester fiber layer 13 is made of high-strength, low-elongation polyester fiber double warp and double weft weave, which can significantly improve the structural strength, wear resistance, and dimensional stability of the composite waistband body 1, preventing deformation and damage caused by repeated stretching during exercise. At the same time, the bamboo fiber skin-friendly layer 11, the copper fiber electromagnetic shielding layer 12, and the wear-resistant polyester fiber layer 13 are all connected by a high-elasticity nylon substrate through warp and weft interweaving. This allows the three-layer structure to work together to have good elasticity and resilience, adapting to the patient's body deformation during exercise, maintaining a tight fit, preventing loosening and displacement due to vibration, and thus ensuring stable lead fixation and reliable ECG signal acquisition.

[0026] Furthermore, the copper fiber electromagnetic shielding layer 12 is made of copper fiber and polyester fiber interwoven to form a mesh shielding structure with a shielding effectiveness of not less than 30dB, which is used to block the influence of electromagnetic interference on electrocardiogram signals in the sports environment. The conductive fiber strip 14 is made of silver fiber conductive material and is continuously sewn into the bottom edge of the inner side of the bamboo fiber skin-friendly layer 11. The antistatic agent is a non-ionic permanent antistatic agent, and one end of the conductive fiber strip 14 can be extended to ground.

[0027] The copper fiber electromagnetic shielding layer 12 is made of copper fiber and polyester fiber interwoven to form a mesh shielding structure with a shielding efficiency of not less than 30dB. It can effectively block electromagnetic interference in the treadmill exercise test environment and avoid problems such as baseline drift and increased noise in the ECG signal. The conductive fiber strip 14 is made of silver fiber conductive material and is continuously sewn into the bottom edge of the inner side of the bamboo fiber skin-friendly layer 11. With the design of extendable grounding, it can quickly discharge static electricity. Combined with the non-ionic permanent antistatic agent added to the bamboo fiber skin-friendly layer 11 and the wear-resistant polyester fiber layer 13, it can suppress the static electricity generated by clothing friction from the source, doubly ensuring the purity and accuracy of ECG signal acquisition and improving the reliability of treadmill test results.

[0028] Furthermore, the rectangular sliding sleeve 21 is slidably sleeved on the outside of the composite waist belt body 1, the elastic pressure plate 28 abuts against the outer side of the toothed plate 24, and the toothed plate 24 is provided with multiple tooth grooves evenly arranged along the height direction on the side away from the pin shaft 22, and the multiple tooth grooves abut against the outer surface of the composite waist belt body 1.

[0029] Furthermore, the top of the rectangular sliding sleeve 21 is provided with a pin hole through which the pin shaft 22 passes and forms a rotational fit. The bottom end face of the pin shaft 22 is provided with a micro screw hole that matches the micro screw 23. The micro screw 23 is screwed into the micro screw hole from bottom to top and fixedly connected to the pin shaft 22 to prevent the pin shaft 22 from coming out of the pin hole axially.

[0030] By moving the lever 25 with a finger, the pin 22 can be rotated within the pin hole of the rectangular sliding sleeve 21, thereby driving the toothed plate 24 to deflect. This causes the toothed groove on the toothed plate 24 to disengage from the contact state with the surface of the composite waist belt body 1. At this time, the rectangular sliding sleeve 21 can slide freely along the composite waist belt body 1, realizing flexible adjustment of the position of the lead fixing component 2. After the adjustment is in place, the lever 25 is released, and the elastic pressure plate 28 will automatically rebound and push the toothed plate 24 back to reset, allowing the toothed groove of the toothed plate 24 to press against the surface of the composite waist belt body 1 again to complete the locking. Combined with the axial limiting and anti-dislodgement effect of the micro screw 23 on the pin 22, the lead fixing component 2 is ensured to be firmly and reliably positioned. Furthermore, several sets of lead fixing components 2 can be set, and their positions can be independently adjusted on the composite waist belt body 1 according to the ECG acquisition requirements to meet the deployment needs of different lead electrode pads.

[0031] Furthermore, a U-shaped wire hole is provided at the bottom of the slot 26 for threading the connecting cable of the lead electrode sheet; the internal cavity of the slot 26 is adapted to snap and fix the protruding snap of the lead electrode sheet; an anti-slip silicone sheet 29 is fixedly provided on the outer surface of the slot 26 for tightly fitting with the backing of the lead electrode sheet to improve the stability and anti-slip performance of the electrode sheet.

[0032] The lead electrode pads are secured by inserting the protruding snaps into the internal cavity of the slot 26. The connecting cables of the lead electrode pads pass smoothly through the U-shaped wire hole at the bottom of the slot 26, avoiding bending and pressure on the cables. At the same time, the anti-slip silicone sheet 29 on the outer surface of the slot 26 fits tightly against the backing of the lead electrode pads, increasing the contact friction and further improving the stability and anti-slip performance of the electrode pads. This ensures that the lead electrode pads will not loosen or fall off during exercise, guaranteeing continuous and stable acquisition of ECG signals.

[0033] Furthermore, a rectangular sleeve 31 and a buckle plate 38 are both fixedly connected to one side of a U-shaped waist belt connector. The U-shaped waist belt connectors are used to connect to both ends of the composite waist belt body 1. The top and bottom surfaces of the buckle plate 38 are rounded. The buckle plate 38 is provided with two sets of limiting grooves 311 at equal intervals along its length. The limiting grooves 311 are engaged with the locking block 34, and one side of the limiting groove 311 is connected to the groove 310.

[0034] Furthermore, the assembly groove 39 is used for assembling the pressing block 33 into the rectangular through groove 32. There are two pressing blocks 33, and the serpentine spring sheet 36 abuts between the receiving grooves 35 of the two pressing blocks 33.

[0035] Furthermore, the slot 37 is used for the buckle plate 38 to be slidably inserted and fitted. The top surface of the buckle plate 38 is uniformly provided with length scale lines along its length direction to visually display the adjustable length and tightness of the buckle plate 38.

[0036] By pressing the two pressing blocks 33, the two press against each other in the rectangular through groove 32 to squeeze the serpentine spring sheet 36, causing the locking block 34 to retract inward. Then, the buckle plate 38 is inserted into the rectangular sleeve 31 through the slot 37. The tightness is adjusted to a suitable degree by referring to the length scale line on the surface of the buckle plate 38. After releasing the pressing blocks 33, the serpentine spring sheet 36 rebounds and pushes the two pressing blocks 33 to reset. The locking block 34 is locked into the corresponding limiting groove 311 on the buckle plate 38. The rounded corner design of the buckle plate 38 allows it to be inserted and slid smoothly. The rectangular sleeve 31 and the buckle plate 38 are connected to the two ends of the composite waist belt body 1 through the U-shaped waist belt connecting seat, thereby realizing the quick connection, length adjustment and firm fixation of the composite waist belt body 1.

[0037] Example 2:

[0038] Please see Figure 9 The rectangular sleeve 31 of the belt buckle 3 of the present invention can also be directly connected to the straps on both sides of the guide dust collection box 4, which makes it easy for the composite belt body 1 to be directly connected to the traditional guide integration box 4.

[0039] In use, first press the two pressing blocks 33 of the belt buckle 3, causing them to press against each other within the rectangular through groove 32, squeezing the serpentine spring plate 36 and causing the locking block 34 to retract inward. Then, insert the buckle plate 38 into the rectangular sleeve 31 through the slot 37. Adjust the tightness to a suitable level by referring to the length scale lines on the surface of the buckle plate 38, and then release the pressing blocks 33. The serpentine spring plate 36 rebounds and pushes the pressing blocks 33 back to their original position, causing the locking block 34 to engage in the limiting groove 311 of the buckle plate 38, thus securing the composite belt body 1. Subsequently, move the lever 25 of the guide fixing component 2, causing the pin 22 to rotate and disengage the toothed plate 24 from the composite belt body 1, thus securing the rectangular sleeve 31. After the sliding sleeve 21 slides along the composite waist belt body 1 to the desired position, the lever 25 is released. The elastic pressure plate 28 pushes the toothed plate 24 to reset and presses the composite waist belt body 1 through the tooth groove to complete the positioning of the lead fixing component 2. Then, the protruding snap of the lead electrode is inserted into the internal cavity of the slot 26. Its connecting cable passes through the U-shaped wire hole at the bottom of the slot 26. The anti-slip silicone sheet 29 on the outer surface of the slot 26 is tightly attached to the electrode backing to achieve fixation. At the same time, the bamboo fiber skin-friendly layer 11 of the composite waist belt body 1 fits the human body, the copper fiber electromagnetic shielding layer 12 blocks electromagnetic interference, and the conductive fiber strip 14 and the antistatic agent work together to eliminate static electricity and ensure stable acquisition of electrocardiogram signals.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
