Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, specifically a postoperative magnetic field monitoring device for an armband-type cardiac pacemaker. Background Technology

[0002] The background for post-pacemaker surgery magnetic field monitoring stems primarily from the potential interaction between the pacemaker and external magnetic fields, which carries the risk of interfering with the pacemaker's normal function. After pacemaker implantation, hospitals typically advise patients to stay away from high-voltage magnetic field areas, such as radar stations and substations, and to remain indoors during thunderstorms to prevent adverse effects on pacemaker function.

[0003] Furthermore, in daily life, the magnetic field fluctuations or weak magnetic field environments generated by everyday electrical appliances such as televisions, induction cookers, and radios can also interfere with the multi-metal components inside the pacemaker, thus affecting its normal operation. This interference may lead to serious consequences such as pacemaker displacement, abnormal heating, functional failure, or arrhythmia, threatening the patient's life. Therefore, patients should pay close attention to both strong and weak magnetic field environments.

[0004] Patients with implanted electronic devices such as pacemakers should avoid environments with magnetic field strength exceeding 5 gauss. However, because patients often lack professional medical knowledge and self-protection awareness, and may lack effective temporary handling capabilities in emergency situations, they can easily and unintentionally cause adverse effects on their pacemakers.

[0005] Based on this, a postoperative magnetic field monitoring device for armband-type cardiac pacemakers is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a postoperative magnetic field monitoring device for an armband-type cardiac pacemaker, in order to address the issue that patients often lack professional medical knowledge and self-protection awareness, and may lack effective temporary handling capabilities in emergency situations, thus they can easily cause adverse effects on the cardiac pacemaker unintentionally.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A postoperative magnetic field monitoring device for an arm-cuffed cardiac pacemaker includes a device housing with a detachable cover. Two mounting shafts are symmetrically mounted on both sides of the housing, each connected to one end of an elastic arm cuff. An opening is provided on one side of the housing, and an inner tongue is fixed to one end of the elastic arm cuff near the opening. A drive structure for tightening and loosening the arm cuff is located inside the housing. The inner tongue passes through the opening and connects to the drive structure inside the housing. A monitoring structure for controlling the drive structure is also located inside the housing. A battery is installed inside the housing to provide power to the drive and monitoring structures.

[0009] Preferably, the drive structure includes a motor installed inside the equipment housing, a shaft fixed to the output end of the motor, the shaft being connected to the inner tongue of the arm belt, the end of the inner tongue of the arm belt away from the shaft being connected to one end of the elastic arm belt, and the motor being connected to the monitoring structure.

[0010] Preferably, the outer wall of the shaft is provided with several burrs.

[0011] Preferably, the monitoring structure includes a processing chip, a triaxial magnetic sensor, and a MOSFET installed inside the equipment housing. The processing chip is electrically connected to the triaxial magnetic sensor, and the triaxial magnetic sensor is electrically connected to the MOSFET. The MOSFET is equipped with electronic switches one, two, three, and four. These electronic switches are divided into two groups, A and B. Group A consists of electronic switches one and four, and group B consists of electronic switches two and three. Group A is used to control the motor to drive the shaft to rotate forward, thereby tightening the elastic armband through the inner tongue of the armband. Group B is used to control the motor to drive the shaft to rotate in reverse, thereby loosening the elastic armband through the inner tongue of the armband.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a triaxial magnetic sensor to monitor changes in the magnetic field value near the patient in real time, and converts the magnetic field value into an electrical signal and transmits it to the processing chip. The processing chip determines the forward and reverse rotation of the motor through the mapping relationship between the magnetic field value and the electrical signal, thereby controlling the tightening or loosening of the elastic armband, thus reminding the patient to stay away from magnetic fields higher than 5 Gauss, which helps to enhance the patient's self-protection awareness and avoid the magnetic field from affecting the normal operation of the heart pacemaker.

[0014] 2. This utility model uses an elastic armband that tightens and loosens to provide reminders, avoiding the negative impact of traditional beeping sounds on patients' emotions and reducing the potential interference of emotional fluctuations on the operation of the pacemaker. When the magnetic field exceeds the limit, the armband automatically tightens to provide a reminder; after leaving the danger zone, the armband loosens to restore normal function. This reminder method is not only effective but also improves the patient's experience and comfort, which is beneficial for patients' emotional management after cardiac surgery.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In one embodiment, such as Figures 1-4 As shown, a postoperative magnetic field monitoring device for an arm-cuffed cardiac pacemaker includes a device housing 4, on which a device cover 3 is detachably installed. Two hanging shafts 1 are symmetrically installed on both sides of the device housing 4, and each hanging shaft 1 is connected to one end of an elastic arm cuff 6. A device opening 9 is provided on one side of the device housing 4. An inner tongue 8 of the arm cuff 6 is fixed to one end of the elastic arm cuff 6 near the device opening 9. A drive structure for tightening and loosening the arm cuff is provided inside the device housing 4. The inner tongue 8 passes through the device opening 9 and enters the interior of the device housing 4 to connect with the drive structure. A monitoring structure for controlling the drive structure is also provided inside the device housing 4. A battery 2 is installed inside the device housing 4 to provide power to the drive structure and the monitoring structure.

[0022] In this embodiment, the magnetic field value around the patient is first monitored in real time by a monitoring structure, and the magnetic field value is converted into an electrical signal. If the monitored magnetic field value is greater than 5 Gauss, the drive structure controlled by the monitoring structure starts to operate, and the drive structure drives the inner tongue 8 of the armband to tighten, thereby tightening the elastic armband 6 to inform the patient to move away from the area; if the patient moves away from the area with a magnetic field value higher than 5 Gauss, the magnetic field value decreases accordingly, and the drive structure controlled by the monitoring structure starts to operate, and the drive structure drives the inner tongue 8 of the armband to relax, thereby slowly relaxing the elastic armband 6 until the elastic armband 6 returns to its normal elastic state.

[0023] In an optional embodiment, the drive structure includes a motor 5 installed inside the device housing 4, with a shaft 7 fixed to the output end of the motor 5. The shaft 7 is connected to an inner tongue 8 of the arm belt, and the end of the inner tongue 8 away from the shaft 7 is connected to one end of the elastic arm belt 6. The motor 5 is connected to a monitoring structure.

[0024] It should be noted that when the monitoring structure detects a magnetic field greater than 5 Gauss, the motor 5 starts to drive the shaft 7 to rotate forward, thereby tightening the inner tongue 8, which in turn tightens the elastic armband 6 to inform the patient to move away from the area; when the patient moves away, the magnetic field value returns to the normal value, the motor 5 drives the shaft 7 to rotate in reverse, the inner tongue 8 relaxes, and the elastic armband 6 returns to its initial state.

[0025] In an optional embodiment, the outer wall of the shaft 7 is provided with a plurality of burrs.

[0026] It should be noted that the burrs can increase the friction at the connection between the shaft 7 and the inner tongue 8 of the arm belt, thereby tightening and loosening the elastic arm belt 6 when the motor 5 drives the shaft 7 to rotate forward and reverse.

[0027] In an optional embodiment, the monitoring structure includes a processing chip 10, a triaxial magnetic sensor 11, and a MOSFET 12 installed inside the device housing 4. The processing chip 10 is electrically connected to the triaxial magnetic sensor 11, and the triaxial magnetic sensor 11 is electrically connected to the MOSFET 12. The MOSFET 12 is equipped with electronic switches 121, 122, 123, and 124. The electronic switches 121, 122, 123, and 124 are divided into two groups, A and B. Group A consists of electronic switches 121 and 124, and group B consists of electronic switches 122 and 123. Group A is used to control the motor 5 to drive the shaft 7 to rotate forward, thereby tightening the elastic armband 6 through the inner tongue 8 of the armband. Group B is used to control the motor 5 to drive the shaft 7 to rotate in reverse, thereby loosening the elastic armband 6 through the inner tongue 8 of the armband.

[0028] It should be noted that, firstly, the changes in the magnetic field value near the patient are monitored in real time by the triaxial magnetic sensor 11, and the magnetic field value is converted into an electrical signal and transmitted to the processing chip 10. The processing chip 10 determines the forward and reverse rotation of the motor 5 through the mapping relationship between the magnetic field value and the electrical signal.

[0029] Specifically, if the magnetic field is greater than 5 Gauss, electronic switches 121 and 124 of MOSFET 12 connect, driving shaft 7 to rotate clockwise, tightening the inner tongue 8, and constricting the elastic armband 6 to alert the patient. After the patient moves away from the weak magnetic field or when the magnetic field fluctuates, electronic switches 122 and 123 of MOSFET 12 connect, driving shaft 7 to rotate counter-clockwise, relaxing the inner tongue 8, and restoring the elastic armband 6.

[0030] The above embodiment discloses a postoperative magnetic field monitoring device for an armband-type cardiac pacemaker. The patient wears the device on his upper arm, and the triaxial magnetic sensor 11 monitors the changes in the magnetic field value near the patient in real time and converts the magnetic field value into an electrical signal, which is then transmitted to the processing chip 10. The processing chip 10 determines the forward and reverse rotation of the motor 5 based on the mapping relationship between the magnetic field value and the electrical signal.

[0031] When the patient feels the elastic armband 6 tightening slowly, it is a reminder that there is a weak magnetic field or magnetic field fluctuation greater than 5 Gauss around the patient, and the patient should leave as soon as possible. When the patient leaves the environment with a weak magnetic field or magnetic field fluctuation, the elastic armband 6 can be loosened slowly as the magnetic field value around the patient decreases.

[0032] Specifically, if the magnetic field value is greater than 5 Gauss, the electronic switches 121 and 124 in MOSFET 12 are connected, and the motor 5 starts to drive the shaft 7 to rotate forward, thereby tightening the inner tongue 8, and thus tightening the elastic armband 6 to inform the patient to move away from the area; if the patient gradually moves away from the weak magnetic field or magnetic field fluctuation environment due to the reminder of the armband tightening, the electronic switches 122 and 123 in MOSFET 12 are connected, and the motor 5 drives the shaft 7 to rotate in reverse, the inner tongue 8 relaxes, until the elastic armband 6 returns to its normal elastic state.

[0033] It should be noted that the battery 2 of this utility model is a PATL371229 battery, the motor 5 is an OT-FA(K)-130(S) micro motor, the processing chip 10 is a low-power processing chip GD32F103C8T6, and the triaxial magnetic sensor 11 is a triaxial magnetic sensor QMC5883L.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
