Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly relates to an electrode device for diagnosing arrhythmia and a method for using the same. Background Art

[0002] Arrhythmia refers to the abnormality of the frequency or rhythm of cardiac beats caused by the origin or conduction disorder of cardiac activities. It is an important group of diseases in cardiovascular diseases. Conventional diagnosis can capture the immediate cardiac electrical activity, intuitively display the cardiac rhythm and electrical conduction, and for common arrhythmias such as premature beats, tachycardia, bradycardia, atrial fibrillation, etc., electrocardiogram can often provide clear diagnostic basis. Dynamic diagnosis can continuously record the electrocardiogram changes of patients for 24 hours or even longer, which is of great significance for capturing sporadic arrhythmias, evaluating the frequency, duration of arrhythmias and their relationship with patients' activities.

[0003] Existing dynamic diagnosis requires patients to wear electrode devices for a long time. Since it is not convenient to carry them out, patients need to lie flat in bed for a long time, which will limit the free activities of patients and make it inconvenient for patients to move normally during the diagnosis process. At the same time, when patients lie on their sides to rest for a long time, because the patient will compress the fixing belt of the electrode device when lying on the side. When the fixing belt is too loose, it is easy for the electrode part of the device to displace, which will also affect the diagnostic result and cause errors in the diagnostic result. When the fixing belt is too tight, it will cause great discomfort to the patient. Although there are currently devices for adjusting the tightness of the fixing belt on the market, the adjustment method is not very simple and requires manual assistance by nurses. Therefore, the present application provides an electrode device for diagnosing arrhythmia and a method for using the same to meet the needs. Summary of the Invention

[0010] Optionally, the restraint straps are respectively wound and connected to the output shafts on both sides of the bipolar motor. The bipolar motor is electrically connected to the control center. The bipolar motor is connected to one of the connecting heads on the connecting plate through a wire. The other connecting head on the connecting plate is connected to the control center through a wire.

[0011] Optionally, conductive plates are fixedly connected to both the upper and lower ends of the stopper.

An elastic spiral ring is arranged between the two stoppers.

[0012] Optionally, the trigger assembly includes a pressing plate. The pressing plate is slidably connected to a fixing plate. One side of the fixing plate is fixedly connected to a guiding plate. A trigger block is slidably connected in the guiding plate. One end of the trigger block is rotatably connected to a trigger part. The guiding plate is fixedly connected to one side of the installation box.

[0013] Optionally, a group of annularly arrayed sliding rods are fixedly connected to one side of the pressing plate.

[0015] The present application also provides a usage method of an electrode device for diagnosing arrhythmia, including the following steps:

[0016] S1. The patient wears the chest strap to the chest and makes the detection electrode closely adhere to the skin at the patient's heart. The heart rate of the patient can be detected through the detection electrode, and the detection result is displayed on the control center.

[0017] S2. When the patient lies flat, the chest strap is in a relaxed state.

[0018] S3. When the patient lies on the side or stands, the chest strap is in a tight state.

[0019] S4. When the patient stands and exercises and sweats at the chest, the patient can, by operating the control center, make the restraint strap relaxed and at the same time inflate the airbag body so that the chest strap can closely adhere to the patient's skin.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] In the above solution, by arranging the airbag assembly, when the patient sweats at the chest, the airbag body will bulge, which can not only increase the contact area with the patient's skin, increase the friction between the airbag body and the patient's skin, avoid the downward movement of the chest strap during exercise, but also avoid the restraint strap strangling the patient's chest and affecting the patient's breathing. When the protruding massage head presses on the patient's skin, local massage can also be performed on the patient to reduce the fatigue feeling of the patient during exercise.

[0022] By setting up the rewinding component, when the patient is in a lying position, the restraint belt will be in a relaxed state, allowing the chest belt to just contact the patient's skin, reducing the compression of the chest belt on the patient, enabling the patient to maintain a comfortable resting state. When the patient lies on their side, the stopper will slide in the arc-shaped groove and cause the corresponding bipolar motor to rotate, rewinding the restraint belt. When the restraint belt is tightened, it will gradually press on the patient. In this way, the patient will feel a certain degree of discomfort, thus reminding the patient to try to maintain a lying resting state.

[0023] By setting up the triggering component, as shown in the figures, when the patient needs to stand and exercise, the restraint belt can be automatically tightened when the patient sits up, allowing the chest belt to closely adhere to the patient's chest, preventing the chest belt from falling off, enabling the patient to also perform heart rate detection during exercise, avoiding the situation of arrhythmia during exercise. At the same time, when the patient is resting, the restraint belt can be automatically relaxed, reducing the sense of restraint when the patient is lying flat and enabling the patient to rest more comfortably. It realizes the heart rate detection of the patient whether the patient is resting or exercising, making the diagnosis result more accurate. Brief Description of the Drawings

[0045] As Figures 1 to 12As shown in the figure, an embodiment of the present invention provides an electrode device for diagnosing arrhythmia, including a chest strap 1. A control center 11 is provided on the surface of one side of the chest strap 1. A detection electrode 12 is provided inside the control center 11. During use, the detection electrode 12 is closely attached to the skin of the patient's heart. An installation box 13 is provided on the other side of the chest strap 1. An airbag assembly 2 is provided inside the chest strap 1. During use, the airbag assembly 2 is closely attached to the patient's skin and can massage the corresponding area. A pair of upper and lower restraint straps 3 are provided in the chest strap 1. One end of the restraint strap 3 is fixedly connected to the chest strap 1, and the other end of the restraint strap 3 is fixedly connected to a winding assembly 4. The winding assembly 4 is provided in the installation box 13. The winding assembly 4 is used to wind the restraint strap 3. A trigger assembly 5 is provided on one side of the winding assembly 4. The trigger assembly 5 is used to assist the winding assembly 4 in winding the restraint strap 3. When performing heart rate monitoring on a patient, first, the chest strap 1 needs to be worn on the patient's chest, and the detection electrode 12 should be located on the skin of the patient's heart. During the patient's rest or exercise, the change in the patient's heart rate will be displayed on the display screen of the control center 11. The staff can record the change in the patient's heart rate at any time by operating the control center 11. When the patient has arrhythmia, the control center 11 will issue a warning to alert the patient and the staff.

[0046] As an implementation method in this embodiment, as Figures 1 to 3 shown, the airbag assembly 2 includes an airbag body 21. One end of the airbag body 21 is connected to an air pump 22 through a trachea. An installation groove is provided inside the airbag body 21. A rubber film 23 is provided in the installation groove of the airbag body 21. The air pump 22 is electrically connected to the control center 11. A group of massage heads 231 arranged in a matrix are provided on the concave side of the rubber film 23. When the patient wears the chest strap 1 and exercises, when the patient sweats at the chest due to exercise, at this time, the patient can operate the control center 11 to make the air pump 22 fill the airbag body 21 with external air. While the airbag body 21 bulges, the bipolar motor 44 in the winding assembly 4 will rotate to release the restraint strap 3, making the restraint strap 3 gradually loose. During the process of the airbag body 21 bulging, the chest strap 1 always closely adheres to the patient's chest. At the same time, the rubber film 23 located on the airbag body 21 will be bulged by the air. At this time, the massage heads 231 inside the rubber film 23 will protrude and press on the patient's skin.

[0047] In this embodiment, as Figures 1 to 3As shown, when the patient sweats on the chest, the airbag body 21 bulges, which can not only increase the contact area with the patient's skin, increase the friction between the airbag body 21 and the patient's skin, avoid the downward movement of the chest strap 1 during exercise, but also prevent the restraint strap 3 from pressing on the patient's chest and affecting the patient's breathing. When the protruding massage head 231 presses on the patient's skin, it can also perform local massage on the patient to reduce the fatigue feeling during the patient's exercise.

[0048] As an implementation method in this embodiment, as Figures 4 to 9As shown, the winding assembly 4 includes a set of mounting plates 41 arranged vertically. A set of stoppers 42 are slidably connected between the two mounting plates 41. Connecting plates 43 are fixedly connected to both ends of the mounting plates 41. Biphasic motors 44 are arranged on both sides of the two connecting plates 43. Arc-shaped grooves 411 are formed in the mounting plates 41. A resistor plate 412 is fixedly connected to the bottom of the arc-shaped groove 411. An insulating plate 413 is arranged in the middle of the resistor plate 412 above. Two connection heads 431 are arranged vertically in the connecting plate 43. Both ends of the resistor plate 412 are respectively connected to the connection heads 431 on the two connecting plates 43 on both sides. Binding straps 3 are respectively wound around the output shafts on both sides of the biphasic motor 44. The biphasic motor 44 is electrically connected to the control center 11. The biphasic motor 44 is connected to one connection head 431 on the connecting plate 43 through a wire. The other connection head 431 on the connecting plate 43 is connected to the control center 11 through a wire. Conductive plates 423 are fixedly connected to both the upper and lower ends of the stopper 42. One side of the conductive plate 423 is connected to a conductive column 425 through a conductive spring 424. The conductive column 425 is slidably connected to the surface of the resistor plate 412. An elastic spiral ring is arranged between the two stoppers 42. When the patient wears the chest strap 1 and lies flat on the bed, the stopper 42 will move to the middle position of the arc-shaped groove 411 under the action of gravity. After the stopper 42 moves to the middle position of the arc-shaped groove 411, the conductive columns 425 above the two stoppers 42 are located at the insulating plate 413 of the upper resistor plate 412. At this time, the upper resistor plate 412 cannot be connected to the lower resistor plate 412. Therefore, the biphasic motor 44 is in a power-off state, and the binding strap 3 stops being wound by the biphasic motor 44. During the patient's breathing process, the binding strap 3 will gradually pull the biphasic motor 44 and gradually loosen, so that the chest strap 1 can just fit on the patient's skin. When the patient lies on the side, the two stoppers 42 will move to one end of the arc-shaped groove 411 under the influence of gravity. During this process, the conductive column 425 will leave the upper insulating plate 413 and move onto the resistor plate 412. At this time, the upper and lower two resistor plates 412 on the corresponding side are connected through the conductive column 425, the conductive spring 424, the conductive plate 423 and the stopper 42, so that the corresponding biphasic motor 44 rotates. When the biphasic motor 44 rotates, it will wind the binding strap 3. When the binding strap 3 is wound, it will tighten on the patient's skin, making the patient feel a tight feeling, so as to remind the patient to reduce the time of lying on the side. When the patient lies flat, the two stoppers 42 will slide to the middle position of the arc-shaped groove 411 again, making the biphasic motor 44 in a power-off state.

[0049] In this embodiment, as Figures 4 to 9As shown, when the patient is in a lying position, the restraint strap 3 will be in a relaxed state, allowing the chest strap 1 to just contact the patient's skin, reducing the pressure of the chest strap 1 on the patient and enabling the patient to maintain a comfortable resting state. When the patient lies on their side, the stopper 42 will slide in the arc-shaped groove 411 and cause the corresponding bipolar motor 44 to rotate, winding up the restraint strap 3. When the restraint strap 3 is wound up, it will gradually press on the patient. In this way, the patient will feel a certain degree of discomfort, thus reminding the patient to try to maintain a lying resting state.

[0050] As an implementation manner in this embodiment, as Figures 7 to 12As shown, the trigger assembly 5 includes a pressing plate 51 which is slidably connected to a fixing plate 52. One side of the fixing plate 52 is fixedly connected to a guiding plate 53. A trigger block 54 is slidably connected in the guiding plate 53. One end of the trigger block 54 is rotatably connected to a trigger part 55. The guiding plate 53 is fixedly connected to one side of the mounting box 13. One side of the pressing plate 51 is fixedly connected with a group of sliding rods 511 arranged in a circular array. The pressing plate 51 is slidably connected to the fixing plate 52 through the sliding rods 511. A first spring 512 is arranged on the sliding rods 511 between the pressing plate 51 and the fixing plate 52. One side of the pressing plate 51 is fixedly connected with a first toothed plate 513. The first toothed plate 513 is meshed and connected with an auxiliary gear 514. The other side of the auxiliary gear 514 is meshed and connected with a second toothed plate 541. The second toothed plate 541 is fixedly connected to the bottom of the trigger block 54. The auxiliary gear 514 is rotatably connected in the guiding plate 53. The trigger part 55 includes two trigger rods 551. The bottom of the trigger rod 551 is fixedly connected with a synchronous gear 552. The synchronous gears 552 at the bottoms of the two trigger rods 551 are meshed and connected. The synchronous gear 552 at the bottom of the trigger rod 551 is rotatably connected in the trigger block 54. An elastic cord 553 is arranged between the two trigger rods 551. One ends of the two trigger rods 551 are respectively located on one side of the two stoppers 42. A retaining groove 421 is formed on the side of the stopper 42 close to the trigger rod 551. When the patient wears the chest strap 1 and lies flat on the bed, the pressing plate 51 is pressed by the patient, so that the bottom of the trigger part 55 is located in the guiding plate 53. At this time, the trigger rod 551 is separated from the stopper 42. When the patient needs to stand up, the patient will first sit up. During the process of sitting up, the bottom of the pressing plate 51 loses pressure. At this time, the first spring 512 compressed between the pressing plate 51 and the fixing plate 52 will extend, causing the pressing plate 51 to move on the fixing plate 52. When the pressing plate 51 moves, the first toothed plate 513 will cause the auxiliary gear 514 to rotate. When the auxiliary gear 514 rotates, it will cause the second toothed plate 541 to move. When the second toothed plate 541 moves, it will push the trigger block 54 out of the guiding plate 53, so that the trigger rod 551 gradually approaches the stopper 42. When the top of the trigger rod 551 abuts against the retaining groove 421 of the stopper 42, the two trigger rods 551 will gradually open towards both ends under the action of the retaining groove 421 and push the two stoppers 42 to move towards both sides. When the pressing plate 51 stops moving, at this time, the conductive columns 425 of the two stoppers 42 are located on both sides of the upper resistance plate 412. At this time, the bipolar motors 44 at both ends of the resistance plate 412 are both powered on. The bipolar motors 44 on both sides wind up the restraint belt 3 at the same time, so that the chest strap 1 can be fixed on the patient's chest to prevent the patient from loosening and falling during the movement. When the patient lies flat, the patient will press the pressing plate 51 on the bed. At this time, the pressing plate 51 rotates the auxiliary gear 514 through the first toothed plate 513, so that the second toothed plate 541 rotates in the reverse direction, and the trigger block 54 will move into the guiding plate 53 under the action of the second toothed plate 541.The trigger rod 551 will separate from the stopper 42. During the separation process, the two trigger rods 551 will return to their original positions under the action of the elastic rope 553. At the same time, the two stoppers 42 will move to the middle position of the arc-shaped groove 411. When the patient lies on their side, the stopper 42 will first slide in the arc-shaped groove 411. When the trigger block 54 is pushed out by the second toothed plate 541, the trigger rod 551 cannot abut against the stopper 42. When the patient lies completely on their side, the conductive column 425 at the top of the stopper 42 has left the position of the insulating plate 413, enabling the bipolar motor 44 on one side to be powered on.,

[0051] In this embodiment, as Figures 7 to 12 shown, when the patient needs to stand and exercise, when the patient sits up, the restraint belt 3 can be automatically tightened, so that the chest belt 1 can closely adhere to the patient's chest, preventing the chest belt 1 from falling off, enabling the patient to also perform heart rate detection during exercise, avoiding the occurrence of arrhythmia during exercise. At the same time, when the patient is resting, the restraint belt 3 can be automatically relaxed, reducing the sense of restraint when the patient lies flat and resting, enabling the patient to rest more comfortably, realizing that the patient's heart rate can be detected whether the patient is resting or exercising, making the diagnosis result more accurate.

[0052] As Figures 1 to 12 shown, the embodiment of the present invention provides a method for using an electrode device for diagnosing arrhythmia, including the following steps:

[0053] S1. The patient wears the chest belt 1 at the chest and makes the detection electrode 12 closely adhere to the skin at the patient's heart. The heart rate of the patient can be detected through the detection electrode 12 and the detection result is displayed on the control center 11;

[0054] S2. When the patient lies flat, the chest belt 1 is in a relaxed state;

[0055] S3. When the patient lies on their side or stands, the chest belt is in a tight state;

[0056] S4. When the patient stands and exercises and sweats at the chest, the patient can operate the control center 11 to relax the restraint belt 3 and at the same time inflate the airbag body 21 so that the chest belt 1 can closely adhere to the patient's skin.

[0057] The working principle of the technical solution provided by the present invention is as follows: When monitoring the heart rate of a patient, first, the chest strap 1 needs to be worn on the patient's chest, and the detection electrode 12 should be located on the skin at the patient's heart. During the patient's rest or exercise, the change in the patient's heart rate will be displayed on the display screen of the control center 11. The staff can record the change in the patient's heart rate at any time by operating the control center 11. When the patient has arrhythmia, the control center 11 will issue a warning to alert the patient and the staff. When the patient wears the chest strap 1 and exercises, when the patient sweats on the chest due to exercise, at this time, the patient can operate the control center 11 to make the air pump 22 fill the airbag body 21 with external air. While the airbag body 21 bulges, the bipolar motor 44 in the winding assembly 4 will rotate to release the restraint strap 3, making the restraint strap 3 gradually loose. During the process of the airbag body 21 bulging, the chest strap 1 always closely adheres to the patient's chest. At the same time, the rubber membrane 23 on the airbag body 21 will be bulged by the air, and at this time, the massage head 231 inside the rubber membrane 23 will protrude and press on the patient's skin. When the patient sweats on the chest, the airbag body 21 will bulge, which can not only increase the contact area with the patient's skin, increase the friction between the airbag body 21 and the patient's skin, prevent the chest strap 1 from moving downward during exercise, but also avoid the restraint strap 3 strangling the patient's chest and affecting the patient's breathing. When the protruding massage head 231 presses on the patient's skin, it can also perform local massage on the patient to reduce the fatigue feeling during the patient's exercise. When the patient wears the chest strap 1 and lies flat on the bed, the block 42 will move to the middle position of the arc groove 411 under the action of gravity. After the block 42 moves to the middle position of the arc groove 411, the conductive columns 425 above the two blocks 42 are located at the insulating plate 413 of the upper resistance plate 412. At this time, the upper resistance plate 412 cannot be connected to the lower resistance plate 412, so the bipolar motor 44 is in a power-off state, and the restraint strap 3 stops being wound by the bipolar motor 44. The restraint strap 3 will gradually pull the bipolar motor 44 and gradually loosen during the patient's breathing process, so that the chest strap 1 can just adhere to the patient's skin. When the patient lies on the side of the bed, the two blocks 42 will move to one end of the arc groove 411 under the influence of gravity. During this process, the conductive column 425 will leave the upper insulating plate 413 and move onto the resistance plate 412. At this time, the upper and lower two resistance plates 412 on the corresponding side are connected through the conductive column 425, the conductive spring 424, the conductive plate 423 and the block 42, so that the corresponding bipolar motor 44 rotates. When the bipolar motor 44 rotates, it will wind the restraint strap 3. When the restraint strap 3 is wound, it will strangle the patient's skin, making the patient feel a tight feeling, thus reminding the patient to reduce the time of lying on the side. When the patient lies flat, the two blocks 42 will slide to the middle position of the arc groove 411 again, making the bipolar motor 44 in a power-off state. When the patient is in a lying flat state,The restraint strap 3 will be in a relaxed state, allowing the chest strap 1 to just contact the patient's skin, reducing the pressure of the chest strap 1 on the patient, enabling the patient to maintain a comfortable resting state. When the patient lies on their side, the stopper 42 will slide in the arc-shaped groove 411 and cause the corresponding bipolar motor 44 to rotate, winding up the restraint strap 3. When the restraint strap 3 is wound up, it will gradually press on the patient. In this way, the patient will feel a certain degree of discomfort, thus reminding the patient to try to maintain a flat resting state. When the patient wears the chest strap 1 and lies flat in bed, the pressing plate 51 is pressed by the patient, causing the bottom of the trigger part 55 to be located in the guide plate 53. At this time, the trigger rod 551 is separated from the stopper 42. When the patient needs to stand up, the patient will first sit up. During the process of sitting up, the bottom of the pressing plate 51 loses pressure. At this time, the first spring 512 compressed between the pressing plate 51 and the fixing plate 52 will extend, causing the pressing plate 51 to move on the fixing plate 52. When the pressing plate 51 moves, the first toothed plate 513 will cause the auxiliary gear 514 to rotate. When the auxiliary gear 514 rotates, it will cause the second toothed plate 541 to move. When the second toothed plate 541 moves, it will push the trigger block 54 out of the guide plate 53, thereby causing the trigger rod 551 to gradually approach the stopper 42. When the top of the trigger rod 551 abuts against the retaining groove 421 of the stopper 42, the two trigger rods 551 will gradually open towards both ends under the action of the retaining groove 421 and push the two stoppers 42 to move to both sides. When the pressing plate 51 stops moving, at this time, the conductive columns 425 of the two stoppers 42 are located on both sides of the upper resistance plate 412. At this time, the bipolar motors 44 at both ends of the resistance plate 412 are both energized, and the bipolar motors 44 on both sides wind up the restraint strap 3 at the same time, so that the chest strap 1 can be fixed on the patient's chest, preventing the chest strap 1 from loosening and falling during the patient's movement. When the patient lies flat, the patient will press the pressing plate 51 on the bed. At this time, the pressing plate 51 rotates the auxiliary gear 514 through the first toothed plate 513, thereby causing the second toothed plate 541 to rotate in the reverse direction. The trigger block 54 will move into the guide plate 53 under the action of the second toothed plate 541, and the trigger rod 551 will be separated from the stopper 42. During the separation process, the two trigger rods 551 will return to their original positions under the action of the elastic cord 553, and at the same time, the two stoppers 42 will move to the middle position of the arc-shaped groove 411. When the patient lies on their side, the stopper 42 will first slide in the arc-shaped groove 411. When the trigger block 54 is pushed out by the second toothed plate 541, the trigger rod 551 cannot abut against the stopper 42. When the patient lies completely on their side, the conductive column 425 at the top of the stopper 42 has left the position of the insulating plate 413, causing one side of the bipolar motor 44 to be energized. When the patient needs to stand up and exercise, when the patient sits up, the restraint strap 3 can be automatically tightened, so that the chest strap 1 can be closely attached to the patient's chest, preventing the chest strap 1 from falling, enabling the patient to also perform heart rate detection during exercise, and avoiding the occurrence of arrhythmia during exercise. At the same time,When the patient is resting, the automatic relaxation of the restraint belt 3 can be achieved, so as to reduce the sense of restraint when the patient is lying flat and resting, enabling the patient to rest more comfortably. The heart rate of the patient can be detected whether the patient is resting or exercising, making the diagnosis result more accurate.
