Description

Technical Field

[0001] This invention belongs to the field of electrocardiogram (ECG) monitoring technology, and specifically relates to an ECG monitoring device based on wireless ECG signal transmission. Background Technology

[0002] Electrocardiogram (ECG) monitoring is a technology that uses electrodes and instruments to monitor a patient's cardiac electrical activity in real time. It is primarily used to detect abnormalities such as arrhythmias and myocardial ischemia, providing a basis for clinical diagnosis and treatment. Its core function is to continuously record ECG waveforms and provide timely warnings of abnormal signals through an alarm system.

[0003] Currently, Chinese patent publication number CN217310325U, published on August 30, 2022, discloses a mobile support for an electrocardiogram (ECG) monitor, including a mobile base, a column on the mobile base, a storage box on the column, and a support platform on the upper end of the column for placing the ECG monitor. The upper end of the storage box is provided with a frame cover, which is rectangular and fits with the upper end of the storage box. One end of the frame cover is hinged to the side wall of the storage box, and the other end has an opening groove for the lead wire to pass through. The opening groove is provided with elastic bands at both ends connected to the inner walls of the opening groove and used to press the lead wires tightly against the side of the storage box. Connection ports are provided on both sides of the side of the storage box, and locking shafts are provided in the connection ports. C-shaped elastic buckles are provided on the frame cover at the position corresponding to the locking shafts and used to lock onto the locking shafts.

[0004] Therefore, in the existing technology, one end of the lead wire is connected to the patient's body using electrode pads and the other end is plugged into the monitor, so as to realize the display of the electrocardiogram signal on the monitor screen; however, when the patient turns over or moves, the lead wire is easily pulled, which may eventually lead to unstable connection of the lead wire and is not conducive to stable acquisition of electrocardiogram signals. Summary of the Invention

[0005] The purpose of this invention is to provide an electrocardiogram (ECG) monitoring device based on wireless ECG signal transmission, which can realize the wireless transmission of ECG signals.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an electrocardiogram (ECG) monitoring device based on wireless ECG signal transmission, comprising a support, an ECG monitor located at the upper end of the support, multiple leads, a connector connected to the multiple leads, and a signal acquisition processor for receiving and acquiring ECG signals for the connector to be inserted into. The signal acquisition processor is further provided with a wireless signal transmission module for transmitting the acquired ECG signals, and the ECG monitor is further provided with a signal receiving module connected to the wireless signal transmission module via a wireless signal.

[0007] By adopting the above technical solution, when performing electrocardiogram (ECG) monitoring, the lead wires are connected to the human body using electrode pads. At the same time, the lead wires are connected to the signal acquisition processor using a connector. The signal acquisition processor can then be stored on the human body. Since the signal acquisition processor is wirelessly connected to the signal receiving module on the ECG monitor via a wireless signal transmission module, the acquired ECG signal can be wirelessly transmitted to the ECG monitor for display on the screen. Compared to the existing technology where the lead wires are directly wired to the ECG monitor, this method facilitates the patient's turning over and movement.

[0008] A further feature of the present invention is that it also includes a waist belt, the two ends of which are bonded together by Velcro fasteners and Velcro female fasteners, and a storage bag is provided on the side wall of the waist belt for storing excess lead wires and signal acquisition processors, and a sealing zipper is provided at the opening of the storage bag.

[0009] By adopting the above technical solution, the patient wears the waist belt through the Velcro tab and the Velcro mother tab. Then, the excess lead wires and signal acquisition processor can be put into the storage bag and the bag is sealed with a zipper. This facilitates the convenient and safe storage of the signal acquisition processor and excess lead wires on the human body.

[0010] A further feature of the present invention is that the bracket is provided with a storage basket for storing the signal acquisition processor in an idle state, and a column extending vertically upward is provided on the side of the storage basket. A hanging box is provided at the upper end of the column, and the hanging box has multiple hanging holes for inserting the ends of multiple lead wires.

[0011] By adopting the above technical solution, when the lead wires are being stored, the storage basket can be used to store the signal acquisition processor when it is not in use. The ends of multiple lead wires can be embedded in the multiple hanging holes on the hanging box. At this time, the lead wires can fall into the storage basket in an orderly manner along the hanging box under their own gravity, which is conducive to the neat storage of the lead wires.

[0012] A further feature of the present invention is that: a storage cylinder is provided on one side of the hanging box for storing multiple electrode plates stacked vertically, with its inner diameter matching the outer diameter of the electrode plates; a retrieval opening is provided on the lower side of the hanging box, which communicates with the storage cylinder and allows a single electrode plate to be removed; a cover plate is provided on the side of the hanging box for sealing the retrieval opening; and slide rails are provided on both sides of the side of the hanging box and on both sides of the cover plate.

[0013] By adopting the above technical solution, the storage tube inside the hanging box can store multiple electrode plates stacked vertically. When an electrode plate needs to be taken out, the cover plate can be slid upward to open the access port, and then the electrode plates can be taken out one by one through the access port.

[0014] A further feature of the present invention is that the buttons on the multiple electrode pads inside the storage tube face downwards, and the bottom of the hanging box has a fastening groove corresponding to the position of the storage tube for the head end of the lead wire to be inserted and fastened to the button on the electrode pad. A support plate is slidably connected inside the hanging box for inserting into the lower end of the storage tube and being embedded between two adjacent electrode pads located at the bottom of the storage tube. The support plate has a U-shaped opening groove corresponding to the position of the button on the electrode pad. The hanging box is provided with a linkage component for moving the support plate toward the lower end of the storage tube after the cover plate moves upwards.

[0015] By adopting the above technical solution, when it is necessary to remove the electrode pads, in order to reduce the contact between human hands and the electrode pads and thus reduce the possibility of contamination, the linkage component first moves the cover plate upward and drives the support plate to move towards the lower end of the storage tube, so that the support plate is embedded between two adjacent electrode pads at the bottom of the storage tube. At this time, the support plate can support the electrode pad at the bottom of the storage tube. Then, after the end of the connecting wire is embedded in the opening groove, it can be aligned with the button of the electrode pad and pressure is applied, so that the end of the connecting wire and the electrode pad complete the button fastening operation. Then, the connecting wire is moved, and the connecting wire can then drive the electrode pad to move out along the retrieval port, which makes it easier and more hygienic to remove the electrode pads.

[0016] A further feature of the present invention is as follows: a sliding sleeve is provided at one end of the support plate away from the storage tube; a guide shaft extending horizontally and through which the sliding sleeve passes is provided inside the hanging box; a return spring is sleeved on the guide shaft, one end of which is connected to the end of the guide shaft and the other end of which is connected to the sliding sleeve; a cover for multiple hanging holes to pass through is also provided on the outside of the hanging box; the linkage assembly includes a connecting shaft rotatably connected to the outer wall of the hanging box and passing through the cover; an elongated hole opened on the side wall of the hanging box corresponding to the position of the support plate; an extension shaft provided on the side of the support plate and passing through the elongated hole; a linkage arm provided on the upper side of the extension shaft; an inner swing arm with one end fixed to the connecting shaft and the other end for abutting against the linkage arm; an outer swing arm with one end fixed to the connecting shaft and located on the outside of the cover; a positioning plate provided on the outer wall of the cover and positioning the lower limit position of the outer swing arm; and a moving shaft with one end connected to the outer wall of the cover and the other end located on the upper side of the outer swing arm.

[0017] By adopting the above technical solution, when it is necessary to remove the electrode sheet, the outer swing arm is swung upward, which then drives the inner swing arm to push the linkage arm, so that the support plate passes into the lower end of the storage tube and is embedded between two adjacent electrode sheets located at the bottom of the storage tube. At the same time, the return spring is compressed, and then the electrode sheet at the retrieval port can be removed. After the electrode sheet is removed, the outer swing arm is released, and the return spring drives the support plate back to its original position under the action of elastic restoring force, so that the next electrode sheet can fall to the retrieval port position for easy retrieval next time.

[0018] A further feature of the present invention is that: a vacuum generator is provided inside the hanging box; an air passage is provided inside the support plate; a suction cup opening is provided on the lower surface of the support plate corresponding to the side position of the electrode sheet and used to attract the release film on the surface of the electrode sheet; an air pipe is provided between the vacuum generator and the support plate for connecting the air passage; a time-delay switch is provided on the outer wall of the cover for the outer swing arm to contact and electrically connected to the vacuum generator; a groove is provided on the side of the outer swing arm for the moving shaft to be embedded; a magnetic ring is provided in the groove for attracting the moving shaft; and a storage slot for storing the release film is provided on the lower side of the hanging box; when the outer swing arm leaves the time-delay switch and swings downward, the vacuum generator still generates an adsorption force on the release film under the delay effect until the support plate moves above the storage slot and the adsorption force is interrupted, and the release film falls into the storage slot.

[0019] By adopting the above technical solution, when the outer swing arm swings upward and the support plate is embedded between two adjacent electrode plates at the bottom of the storage tube, the outer swing arm abuts against the delay switch, the delay switch is triggered to start the vacuum generator, and then the vacuum generator can generate suction at the suction cup opening through the air pipe and air channel. The suction can cause the release film of the electrode plate to be adsorbed onto the support plate. When the electrode plate is pulled out of the access port, the release film on the surface of the electrode plate can be peeled off at the same time, so that the electrode plate can be directly applied to human skin.

[0020] When the electrode sheet is removed and the outer swing arm swings downward after leaving the delay switch, the reset spring first drives the support plate back to its original position under the action of elastic restoring force. The vacuum generator continues to generate an adsorption force on the release film under the delay action until the support plate moves above the storage groove and the adsorption force is interrupted, and the release film falls into the storage groove, thereby realizing the storage of the release film.

[0021] A further feature of the present invention is that when the support plate is inserted into the lower end of the storage tube and embedded between two adjacent electrode plates located at the bottom of the storage tube, the end of the support plate is attached to the inner wall of the dispensing port.

[0022] By adopting the above technical solution, when the support plate is inserted into the lower end of the storage tube and embedded between two adjacent electrode plates at the bottom of the storage tube, the end of the support plate is attached to the inner wall of the dispensing port. At this time, the inner wall of the dispensing port can support the support plate and prevent the support plate from being bent under pressure.

[0023] A further feature of the present invention is that a light box is provided inside the hanging box and located on the side wall of the storage tube, and ultraviolet lamps for irradiating the electrode plates and the ends of the lead wires with ultraviolet light are provided on both sides of the light box.

[0024] By adopting the above technical solution, the light box inside the hanging box is equipped with ultraviolet lamps on both sides. At this time, the ultraviolet lamps on both sides can sterilize and disinfect the electrode plates and the ends of the lead wires inserted into the hanging box, which facilitates the safe use of the electrode plates and the ends of the lead wires.

[0025] The beneficial effects of this invention are as follows: Firstly, when performing electrocardiogram (ECG) monitoring, the lead wire is connected to the human body using electrode pads, and simultaneously, the lead wire is connected to the signal acquisition processor using a connector. The signal acquisition processor can then be stored on the human body via a belt and a storage bag. Furthermore, since the signal acquisition processor is wirelessly connected to the signal receiving module on the ECG monitor via a wireless signal transmission module, the acquired ECG signal can be wirelessly transmitted to the ECG monitor for display on the screen. Compared to the prior art where the lead wire is directly wired to the ECG monitor, this invention facilitates the patient's turning over and movement.

[0026] When the lead wires are being stored, the storage basket can be used to store the signal acquisition processor when it is not in use. The ends of the multiple lead wires can be embedded in the multiple hanging holes on the hanging box for ultraviolet sterilization. At this time, the lead wires can fall into the storage basket in an orderly manner along the hanging box under their own gravity, which is conducive to the neat storage of the lead wires.

[0027] Meanwhile, the storage tube inside the hanging box allows multiple electrode pads to be stacked vertically for storage. When it is necessary to remove an electrode pad, in order to reduce the contact between the human hand and the electrode pad and thus reduce the possibility of contamination, the outer swing arm is first swung upward, which then drives the inner swing arm to push the linkage arm, so that the support plate passes into the lower end of the storage tube and is embedded between two adjacent electrode pads at the bottom of the storage tube. The end of the support plate is attached to the inner wall of the retrieval port, and the return spring is compressed. At this time, the support plate can support the electrode pad at the bottom of the storage tube. Then, the end of the lead wire is embedded in the opening slot and aligned with the button of the electrode pad. After applying pressure, the end of the lead wire and the electrode pad complete the button-locking operation. Then, the lead wire is moved, and the lead wire can then move the electrode pad out along the retrieval port. Finally, it is convenient and hygienic to remove the electrode pad.

[0028] When the outer swing arm swings upward and the support plate is embedded between two adjacent electrode plates at the bottom of the storage cylinder, the outer swing arm abuts against the delay switch, triggering the delay switch and activating the vacuum generator. The vacuum generator then generates suction at the suction cup opening through the air pipe and air passage. This suction causes the release film of the electrode plate to adhere to the support plate. When the electrode plate is pulled out of the access port, the release film on the surface of the electrode plate can be peeled off, making it convenient for the electrode plate to be directly applied to human skin. When the electrode plate is removed and the outer swing arm swings downward after leaving the delay switch, the return spring, under the action of elastic restoring force, first drives the support plate back to its original position. The vacuum generator continues to generate suction force on the release film under the delay action until the support plate moves above the storage slot, at which point the suction force is interrupted, and the release film falls into the storage slot, thus achieving the storage of the release film.

[0044] Reference Figure 3 , Figure 4 , Figure 5The bracket 1 is also bolted to a storage basket 12 for storing the signal acquisition processor 3 when idle. A vertically extending column 13 is bolted to the side of the storage basket 12, and a hanging box 5 is bolted to the upper end of the column 13. The hanging box 5 has multiple hanging holes 51 for inserting the ends of multiple lead wires 2. Simultaneously, a storage cylinder 52 is integrally formed on one side of the hanging box 5, allowing multiple electrode plates 10 to be stacked vertically and with its inner diameter matching the outer diameter of the electrode plates 10. The button 101 of the multiple electrode plates 10 inside the storage cylinder 52 faces downwards, leaving a gap between adjacent electrode plates 10. The lower side of the container has a retrieval port 53 that communicates with the inside of the storage cylinder 52 and allows for the removal of individual electrode pieces 10. This allows new electrode pieces to be stored from the top of the storage cylinder 52 and old electrode pieces to be retrieved from the bottom of the storage cylinder 52. The side of the hanging box 5 is provided with a cover plate 54 for sealing the retrieval port 53. Slide rails 55 are integrally provided on both sides of the side of the hanging box 5 and on both sides of the cover plate 54, allowing the cover plate 54 to slide up and down on the side of the hanging box 5. At the same time, a light box 59 is provided inside the hanging box 5 and on the side wall of the storage cylinder 52. Ultraviolet lamps 591 are installed on both sides of the light box 59 for irradiating the electrode pieces 10 and the ends of the connecting wires 2 with ultraviolet light.

[0045] Reference Figure 4 , Figure 5 , Figure 6 The bottom of the hanging box 5 is also provided with a fastening groove 56, which corresponds to the position of the storage tube 52 and allows the head end of the connecting wire 2 to be inserted and fastened with the button 101 of the electrode piece 10. A support plate 6 is slidably connected inside the hanging box 5. The support plate 6 can be inserted into the lower end of the storage tube 52 and embedded between two adjacent electrode pieces 10 located at the bottom of the storage tube 52. The end of the support plate 6 is arc-shaped, and a U-shaped opening groove 61 corresponding to the position of the button 101 of the electrode piece 10 is provided on the support plate 6. A sliding sleeve 62 is integrally provided at the end of the support plate 6 away from the storage tube 52. A guide shaft 57 extending horizontally and through which the sliding sleeve 62 passes is fixed inside the hanging box 5 by bolts. A return spring 571 is sleeved on the guide shaft 57, with one end connected to the end of the guide shaft 57 and the other end connected to the sliding sleeve 62.

[0046] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8The outer side of the hanging box 5 is also bolted with a cover 8, which has a space inside. Multiple hanging holes 51 pass through the cover 8. The hanging box 5 is also equipped with a linkage assembly 7 for moving the support plate 6 towards the lower end of the storage cylinder 52 after the cover plate 54 moves upward. This linkage assembly 7 includes a connecting shaft 71, an elongated hole 72, an extension shaft 73, a linkage arm 74, an inner swing arm 75, an outer swing arm 76, a positioning plate 77, and a moving shaft 78. The connecting shaft 71 is rotatably connected to the outer wall of the hanging box 5 via bearings and passes through the cover 8. The elongated hole 72 is formed on the side wall of the hanging box 5, corresponding to the position of the support plate 6. The extension shaft 73 is welded to the side of the support plate 6 and passes through the elongated hole 72. The linkage arm... 74 is integrally set on the upper side of the extension shaft 73. The inner swing arm 75 is fixed at one end to the connecting shaft 71 and the other end is used to abut against the linkage arm 74. The inner swing arm 75 is located inside the cover 8, while the outer swing arm 76 is fixed at one end to the connecting shaft 71 and located outside the cover 8. At the same time, the positioning plate 77 is fixed to the outer wall of the cover 8 and positions the lower limit position of the outer swing arm 76. The moving shaft 78 is connected at one end to the outer wall of the cover 54 and the other end is located above the outer swing arm 76. When the support plate 6 is inserted into the lower end of the storage tube 52 and embedded between two adjacent electrode plates 10 at the bottom of the storage tube 52, the end of the support plate 6 is attached to the inner wall of the access port 53 (see reference). Figure 5 ).

[0047] Reference Figure 5 , Figure 9 , Figure 10 The hanging box 5 also houses a vacuum generator 9, while the support plate 6 has an air passage 63. The lower surface of the support plate 6 has a suction cup opening 64 corresponding to the side of the electrode sheet 10, used to hold the release film 102 on the surface of the electrode sheet 10. An air pipe 91 is provided between the vacuum generator 9 and the support plate 6 for connecting to the air passage 63. Simultaneously, the outer wall of the cover 8 is equipped with a time-delay switch 81 for the outer swing arm 76 to contact and electrically connect to the vacuum generator 9. The time-delay switch 81 has a delayed shutdown function. The side of the swing arm 76 is provided with a groove 761 for the moving shaft 78 to be inserted. A magnetic ring 762 for attracting the moving shaft 78 is fixed in the groove 761. The lower side of the hanging box 5 is also integrally provided with a storage groove 58 for storing the release film 102. When the outer swing arm 76 leaves the delay switch 81 and swings downward, the vacuum generator 9 still generates an adsorption force on the release film 102 under the delay effect until the support plate 6 moves above the storage groove 58 and the adsorption force is interrupted, and the release film 102 falls into the storage groove 58.

[0048] Principle: First, when performing ECG monitoring, lead wire 2 is connected to the human body via electrode pads 10. At the same time, lead wire 2 is connected to signal acquisition processor 3 via connector 21. Signal acquisition processor 3 can be stored on the human body via belt 4 and storage bag 41. Since signal acquisition processor 3 is wirelessly connected to the signal receiving module on ECG monitor 11 via wireless signal transmission module, the acquired ECG signal can be wirelessly transmitted to ECG monitor 11 for screen display. Compared with the existing technology where lead wire 2 is directly wired to ECG monitor 11, this makes it easier for the patient to turn over and move.

[0049] When the lead wire 2 is being stored, the storage basket 12 can be used to store the signal acquisition processor 3 when it is not in use. The ends of the multiple lead wires 2 can be embedded in the multiple hanging holes 51 on the hanging box 5 for ultraviolet sterilization. At this time, the lead wires 2 can fall into the storage basket 12 in an orderly manner along the hanging box 5 under their own gravity, which is conducive to the neat storage of the lead wires 2.

[0050] Meanwhile, the storage tube 52 inside the hanging box 5 provides storage for multiple electrode plates 10 stacked vertically. When it is necessary to remove an electrode plate 10, in order to reduce contact between the human hand and the electrode plate 10 and thus reduce the possibility of contamination, the outer swing arm 76 is first swung upward. This causes the cover plate 54 to move upward via the moving shaft 78, thereby opening the access port 53. The moving shaft 78 is embedded in the groove 761 and attracted to the magnetic ring 762, thus positioning the upward swing position of the outer swing arm 76. At this time, the outer swing arm 76 can drive the inner swing arm 75 to push the linkage arm 74, so that the support plate 6 passes into the lower end of the storage tube 52 and is embedded in the storage tube. At the position between two adjacent electrode pieces 10 at the bottom of the storage cylinder 52, and with the end of the support plate 6 attached to the inner wall of the access port 53, the return spring 571 is compressed. At this time, the support plate 6 can support the electrode piece 10 at the bottom of the storage cylinder 52. Then, after the head end of the connecting wire 2 is embedded in the opening slot 61, it can be aligned with the button 101 of the electrode piece 10 and pressure is applied, so that the head end of the connecting wire 2 and the electrode piece 10 complete the button fastening operation. Then, the connecting wire 2 is moved, and the connecting wire 2 can drive the electrode piece 10 to move out along the access port 53. Finally, it is convenient and hygienic to remove the electrode piece 10.

[0051] When the outer swing arm 76 swings upward and the support plate 6 is embedded between two adjacent electrode pieces 10 at the bottom of the storage cylinder 52, the outer swing arm 76 abuts against the delay switch 81, triggering the delay switch 81 and activating the vacuum generator 9. Subsequently, the vacuum generator 9 generates suction at the suction cup opening 64 through the air pipe 91 and air passage 63. This suction causes the release film 102 of the electrode piece 10 to adhere to the support plate 6. When the electrode piece 10 is pulled out of the access port 53, the release film on the surface of the electrode piece 10 can be peeled off. The release film 102 allows the electrode pad 10 to be directly applied to human skin. When the electrode pad 10 is removed and the outer swing arm 76 is manually pressed down so that it swings downward after leaving the delay switch 81, the reset spring 571 first drives the support plate 6 back to its original position under the action of elastic restoring force. The vacuum generator 9 continues to generate an adsorption force on the release film 102 under the delay action until the support plate 6 moves above the storage groove 58 and the adsorption force is interrupted. The release film 102 falls into the storage groove 58, thereby realizing the storage of the release film 102.
