Description
Technical Field
The present invention relates to an external cardioversion defibrillation combination device, and more particularly, to a wearable cardioversion defibrillation combination device for monitoring and treating malignant arrhythmia events.
Background
When a person suffers from some type of arrhythmia, the result may be a reduction in blood flow to various parts of the body. Some patients may even experience cardiac arrest (SCA) due to arrhythmia. SCA can quickly lead to death, for example within 10 minutes, unless temporary treatment is performed.
Some people have an increased risk of SCA, and people at higher risk of SCA include patients with heart attacks or with previous SCA attacks. These people are often recommended to receive an Implantable Cardioverter Defibrillator (ICD). ICDs are surgically implanted in the chest cavity and continuously monitor the patient for cardiac parameter information, such as electrocardiogram signals (ECG). If certain types of arrhythmias are detected, the ICD delivers a shock through the heart.
These people are sometimes provided with an external cardioversion defibrillation device (wearable cardioversion defibrillation device) before being determined to have an increased risk of SCA and before accepting implantation of an ICD. Extracorporeal cardioversion defibrillation devices typically include a harness, vest, or other garment to be worn by the patient. The external cardioversion-defibrillation combination also includes electronic components, such as external electrodes and a controller, connected to a harness, vest, or other garment. When the patient wears the external cardioversion defibrillation combo device, the external electrodes can make good electrical contact with the patient's skin, thus helping to detect the patient's electrocardiogram. If a shockable arrhythmia is detected, the defibrillator will shock the patient's body appropriately so that the shock vector passes through the heart.
There are some patients in the clinic who are at risk of sudden cardiac death but who have short-term indications for implantable cardioverter defibrillators, or who have indications but short-term failure to newly install or replace an ICD. As a further precaution, people who have been determined to have an increased risk of SCA are sometimes given an external cardioversion defibrillation device to wear until their ICD is implanted. When the patient wears the external cardioversion defibrillation combo device, the electrodes may make good electrical contact with the patient's skin, and thus may help sense the patient's electrocardiogram signal (ECG). If a shockable arrhythmia is detected from an electrocardiogram signal (ECG) and, therefore, an appropriate shock is delivered through the heart. This can restart the patient's heart, saving their lives.
Because the external cardioversion and defibrillation combined equipment does not necessarily completely match the body shape of a patient and the equipment shell is hard, more interference factors exist in the process of sensing electrocardiogram signals (ECG), and accurate sensing and analysis of heart parameter data such as the electrocardiogram signals (ECG) become difficult. The existing Wearable Cardioverter Defibrillator (WCD) has more interference factors in the process of autonomously finishing electrocardiogram signal (ECG) sensing, analysis and defibrillation treatment.

The priority of the event is divided into a first priority, a second priority, a third priority, a fourth priority and the like, and the actual classification level of the priority can be adjusted and set according to specific actual conditions.

Because the external cardioversion and defibrillation combined equipment does not necessarily completely match the body shape of a patient and the equipment shell is hard, more interference factors exist in the process of sensing electrocardiogram signals (ECG), and the sensing of heart parameter data such as the electrocardiogram signals (ECG) becomes more critical. In the combined external cardioversion and defibrillation apparatus, since sensing of a cardiac parameter such as an Electrocardiogram (ECG) signal is performed outside the body through the skin, body tissues and bones, and monitoring of a specific cardiac parameter is affected by noise, temperature, obesity, and the state of contact between an electrode and the skin of a patient, the measured cardiac parameter has a certain error from actual data. To reduce such errors, the electrodes should be as close to the patient's skin as possible; meanwhile, a plurality of pairs of sensing electrodes can be arranged in the medical equipment 500 worn by the patient, so that the sensing accuracy is enhanced, and the sensing error is reduced. The set of electrodes is placed on a medical device 500, is capable of electrically engaging the patient's skin when worn by the patient, and is capable of sensing cardiac parameter information from the patient.

Fig. 6 is a flow chart of a working method of the external cardioversion-defibrillation combination device. The medical device 500 is configured to sense a cardiac parameter of a patient, such as an electrocardiogram signal (ECG), via a sensing module of the medical device 500, see step 602. The communication module of the medical device 500 then transmits the cardiac parameter, e.g., an electrocardiogram signal (ECG), to the remote analysis device 408, see step 610. Before the medical device 500 transmits data to the remote analysis device 408 or before the remote analysis device 408 receives the received data, the medical device 500 and the remote analysis device 408 issue commands to respectively detect whether the communication connection between the two devices is good, step 604, and step 610 is only entered if the two devices detect good contact or at least one of the two devices detects good contact. In the event that the medical device 500 and the remote analysis device 408 detect a poor communication connection, an alarm 606 is issued, and then the processor of the medical device 500 or the remote analysis device 408 performs a retest and reconnect 608, and if the alarm has not been touched, a human check may be performed on the operating status, etc. of the medical device 500 and the remote analysis device 408 and the spatial distance between the two. The alarms are respectively set according to the priority of the event, so that the priority conditions of the event can be distinguished according to the alarms with different degrees. The priority of the event is divided into a first priority, a second priority, a third priority, a fourth priority and the like, and the actual classification level of the priority can be adjusted and set according to specific actual conditions. For example, an alarm for a priority event is set to sound 5 consecutive times, and the occurrence of the whistling sound repeats 3 times, each time with 3 seconds intervals; setting the alarms with the second priority level to continuously sound 4 times; alarms of equal priority are set to whistle 3 times in succession, and so on. Alarms of different priorities may also be set to different colored light flashes or a combination of light flashes and alarm sounds. After the remote analysis device 408 receives the cardiac parameter information from the medical device 500, the processor analyzes and processes the sensed cardiac parameter 612, identifies whether a malignant arrhythmia event occurs or whether a malignant arrhythmia early warning state is entered and returns an analysis and identification result, the remote analysis device 408 judges whether defibrillation treatment is performed according to the analysis and identification result 614, and if a ventricular fibrillation event is not detected, the remote analysis device continues to sense the cardiac parameter (electrocardiogram (ECG) and the like); if a ventricular fibrillation event is detected, the remote analysis device 408 sends a defibrillation command to the medical device 500, step 616, and the medical device 500 receives the therapy command and then shock defibrillation therapy 618.

Taking the example that the patient 100 wears the medical device 500, a method for the patient to wear the medical device 500 and a construction principle of the medical device 500 are specifically explained. Some embodiments of an extracorporeal cardioversion defibrillation device may initiate defibrillation (or delay defibrillation) based on a variety of inputs, of which Electrocardiogram Signals (ECGs) are only one.

The analysis of cardiac parameter signals by the present invention is less disturbed by factors than in a WCD, reducing analysis errors. The medical device 500 worn by the patient only senses the cardiac parameter signals and does not need to analyze and process the data like a WCD, which also reduces the workload of the medical device 500 attached to the patient and increases the sensing accuracy. By providing multiple pairs of sensing electrodes within the medical device 500 worn by the patient, sensing accuracy is enhanced and redundancy of sensing and therapeutic signals is reduced.
