The medical apparatus is hand-held and enables operation of an initial-medical function or initial-state function. The medical apparatus is capable of accepting and operationally integrating into the medical apparatus the contents of an adaptor kit to enable a new medical function. Each adaptor kit includes at least one adaptor-kit cartridge and at least one accessory. Added steps include: using the medical apparatus to perform the initial-medical function or initial-state function; providing a first, a second, and a third adaptor kit to enable the medical apparatus to function as: a wearable automated external defibrillator (AED) with disposable electrode pads; as a wAED with disposable electrode pads; and as a means for taking an electrocardiogram (ECG). ## Claims ### Claim 1 A method of using a medical apparatus, the method comprising the step of: providing the medical apparatus configured: to be hand-held by a person; to enable use of an initial-medical function for the medical apparatus; and to accept and operationally integrate into the medical apparatus any contents in at least one adaptor kit, wherein the contents of each adaptor kit comprises at least one adaptor-kit cartridge configured to be attached to the medical apparatus, each adaptor-kit cartridge further configured to operationally integrate with the medical apparatus either alone or with another adaptor-kit cartridge; and each adaptor kit further comprises at least one accessory, wherein the adaptor-kit cartridge and the at least one accessory are configured to enable a new medical function for the medical apparatus. ### Claim 2 (depends on 1) The method of claim 1, further comprising the step of using the medical apparatus to perform at least one initial-medical function. ### Claim 3 (depends on 1) The method of claim 1, further comprising the steps of: choosing the initial-medical function from one or more in the group consisting of: taking an electrocardiogram (ECG) of the person; measuring blood pressure within the person; measuring blood composition within the person; measuring body temperature of the person; measuring a heart rate of the person; measuring acceleration of a chest of the person undergoing cardiopulmonary resuscitation (CPR); coaching in delivery of a medical function; and performing automated external defibrillation of the person. ### Claim 4 (depends on 1) The method of claim 1, further comprising the steps of: updating medical device firmware or software; performing at least one pre-programmed self-test of the medical apparatus; and providing status information about the medical apparatus. ### Claim 5 (depends on 1) The method of claim 1, further comprising the steps of: selecting the initial-medical function as taking an electrocardiogram (ECG) of the person, identifying a need for an electrocardiogram from the person, the person having bare skin accessible to at least two separated sensors, the at least two separated sensors operationally connected to the medical apparatus; and touching the bare skin to the at least two separated sensors. ### Claim 6 (depends on 5) The method of claim 5, further comprising the step of configuring the at least two separated sensors to be functional when the person places a finger on each of the at least two separated sensors. ### Claim 7 (depends on 5) The method of claim 5, further comprising the step of providing the medical apparatus with multiple leads for use in taking the ECG. ### Claim 8 (depends on 1) The method of claim 1, further comprising the step of: providing an AED adaptor kit, the AED adaptor kit configured to enable the medical apparatus to perform a new medical function of a reusable non-wearable automated external defibrillator (AED), the AED adaptor kit comprises: an AED cartridge; and disposable electrode pads. ### Claim 9 (depends on 8) The method of claim 8, further comprising the steps of: connecting the AED cartridge to the medical apparatus to enable its operation; and placing on the person two of the disposable electrode pads. ### Claim 10 (depends on 8) The method of claim 8, further comprising the step of configuring the AED cartridge to store each of the disposable electrode pads while each such disposable electrode pad is electrically connected to the AED cartridge. ### Claim 11 (depends on 1) The method of claim 1, further comprising the step of: providing a wAED adaptor kit, the wAED adaptor kit configured to enable the medical apparatus to perform a first new medical function of a wearable automated external defibrillator (wAED), the wAED adaptor kit comprises a wAED cartridge configured to attach to, and operationally integrate with, the medical apparatus; and a harness; and further comprises the step of securing the harness on the person. ### Claim 12 (depends on 11) The method of claim 11, wherein the wAED adaptor kit further comprises disposable electrode pads. ### Claim 13 (depends on 12) The method of claim 12, further comprising the steps of: connecting the wAED cartridge to the medical apparatus; and attaching the disposable electrode pads to the person. ### Claim 14 (depends on 8) The method of claim 8, further comprising the steps of: connecting the wAED cartridge to the medical apparatus to enable its operation; and placing on the person two of the disposable electrode pads. ### Claim 15 (depends on 1) The method of claim 1, further comprising the steps of: providing an ECG adaptor kit, the ECG adaptor kit configured to enable the medical apparatus to perform a third new medical function of taking an electrocardiogram (ECG), the ECG adaptor kit comprising: an ECG cartridge; and a plurality of sensors configured to measure a magnitude and direction of electrical currents in a heart during each heartbeat. ### Claim 16 A method of using a medical apparatus, the method comprising the steps of: providing the medical apparatus configured to perform an initial-state function; the medical apparatus further configured to be modified by the addition of contents of one or more adaptor kits to perform a new medical function; the medical apparatus further configured to be hand-held by a person; and to accept and operationally integrate into the medical apparatus, the contents in a wearable automated external defibrillator adaptor kit (a wAED adaptor kit); the contents of the wAED adaptor kit comprising a wAED cartridge and at least one accessory; providing a harness and disposable electrode pads, wherein the harness is configured: to be secured on the person and attached to the medical apparatus; and providing the wAED adaptor kit, wherein the wAED cartridge and the harness are configured to be accepted and to be operationally integrated into the medical apparatus and further configured to enable the medical apparatus to perform a new medical function of a wearable automated external defibrillator (wAED). ### Claim 17 (depends on 16) The method of claim 16, further comprising the steps of: attaching the wAED cartridge to the medical apparatus; adhering two disposable electrode pads to the person; and electrically connecting the disposable electrode pads to the medical apparatus.
