(15) By further inventive principles of the present invention, FIG. 4 illustrates a docking of portable patient monitor 40 to defibrillator 30 via therapy docking station 60.

(16) Specifically, defibrillator 30 incorporates: (1) a display 31 for textually and/or graphically showing alarm and/or therapy delivery status, (2) an user interface 32 for selectively controlling an execution and/or the display of the electrical therapy(ies), (3) a therapy controller 33 for automatically and/or user control execution of (a) the electrical therapy(ies) (e.g., a defibrillation shock, a synchronized cardioversion and a transcutaneous pacing, (b) patient parameter measurement(s) (e.g., ECG, SpO2, NIBP, EtCO2, temperature and/or IBP), (c) data management (e.g., event recordings and transmissions), and (d) wired/wireless data communication with portable patient monitor 40, patient data repository 80 and/or a monitoring center 81; and (4) rechargeable battery(ies) 34 rechargeable by power source 70.

(17) Defibrillator 30 and monitor 40 further incorporate docking interfaces 35 and 45, and therapy docking station 60 establishes a connection 61 between docking interfaces 35 and 45 to facilitate: (1) a secure coupling of defibrillator 30 and monitor 40 via a mechanical coupler (not shown) (e.g., a quick-connect/release latch); (2) a data transfer between defibrillator 30 and monitor 40 (e.g., a network, serial and/or parallel galvanic connection) (Alternatively, wireless communications such as Wi-Fi or Bluetooth may be utilized); and (3) an electrical powering of monitor 40 as needed (e.g., a galvanic connection or inductive coupling).

(18) In practice, (1) the patient parameter measurements by defibrillator 30 may be inclusive or exclusive of some or all of the patient parameter measurements by portable patient monitor 40; (2) portable patient monitor 40 again may be capable of being docked with other medical device modules via docking station 60 (e.g., imaging devices, diagnostic ECG devices, fetal monitors, etc.); (3) display 41 of portable patient monitor 40 may be hidden when docked with defibrillator 30 whereby all of patient parameter measurement(s) by portable patient monitor 40 is displayed on defibrillator 30; (4) display 41 of portable patient monitor 40 may be visible when docked with defibrillator 30 whereby portable patient monitor 40 displays the patient parameter measurement(s) by portable patient monitor 40; (5) display 41 of portable patient monitor 40 may be visible when docked with defibrillator 30 whereby defibrillator 30 and portable patient monitor 40 collectively or divisibly displays the patient parameter measurement(s) by portable patient monitor 40; (6) user interface 42 of portable patient monitor 40 may be hidden when docked with defibrillator 30 whereby user interface 32 of defibrillator 30 controls patient parameter measurements by portable patient monitor 40; (7) user interface 42 of portable patient monitor 40 may be visible when docked with defibrillator 30 whereby user interface 42 of portable patient monitor controls patient parameter measurements by portable patient monitor 40; (8) user interface 42 of portable patient monitor 40 may be visible when docked with bedside patient monitor 20 whereby user interface 42 of portable patient monitor controls part or all of the patient parameter measurements by defibrillator 30; and (9) therapy docking station 60 may be a stand-alone docking station, incorporated within defibrillator 30 or portable patient monitor 40, or integrated with monitor docking station 50 (FIG. 3).

(19) Referring to FIG. 2, in a standard operation, bedside patient monitor 20 is capable of patient parameter measurements without or without connectivity to portable patient monitor 40, and defibrillator 30 likewise is capable of delivering basic electrical therapy(ies) with or without connectivity with portable patient monitor 40.

(20) When portable patient monitor 40 is docked with bedside patient monitor 20, monitors 20 and 40 operate as a single monitor with consistent appearance and behaviors for user interface display and controls. When the portable patient monitor 40 is undocked from bedside patient monitor 20, portable patient monitor 40 continues to operate under battery power with full patient monitoring capabilities including, but not limited to, display, user controls and data management.

(21) Defibrillator 30 requires leads ECG monitoring to deliver a shock for synchronized cardioversion or delivery of a pace pulse due to absence of an intrinsic heartbeat (i.e. demand pacing or synchronized pacing). When portable patient monitor 40 is docked with defibrillator 30, portable patient monitor 40 includes measurement of the patient's leads ECG via 3, 4, 5, or more electrodes 13c attached to patient 11 whereby the data connection with the defibrillator 30 provides low latency to ensure appropriate timing of a synchronized shock or synchronized pacing.

(22) Concurrently or alternatively, defibrillator 30 may include measurement of the patient's leads ECG via 3, 4, 5, or more electrodes attached to the patient 11 in an embodiment when the leads ECG are acquired by portable patient monitor 40.

(23) Docking stations 50 and 60 provide quick attach and quick release capability, and secure attachment for robust power and data communication connections. In one embodiment, the power and data communications use a galvanic connection where the electrical energy flows via electrically conductive paths through wires and connectors (not shown). In another embodiment, the power and data communications may use wireless techniques (e.g., Wi-Fi or Bluetooth) for data communication and inductive coupling for power.

(24) Portable patient monitor 40 manages patient data as it operates both when docked or undocked. In one embodiment, the patient data of portable patient monitor 40 may be transmitted to bedside patient monitor 20 or defibrillator 30, or directly to a patient data repository 80 (FIGS. 3 and 4) (e.g. an electronic Patient Care Reporting (ePCR) system such as Zoll RescueNet) or directly to central patient monitoring station 81 (FIGS. 3 and 4) (e.g. the Philips Intellivue Information Center). When the portable patient monitor 40 is docked, the patient data may be transferred to bedside patient monitor 20 or defibrillator 30 via the wired or wireless data communication mechanism. When portable patient monitor 40 is not docked, the patient data of portable patient monitor 40 may be transferred wirelessly to bedside patient monitor 20 or defibrillator 30. In another embodiment, the portable patient monitor 40 may temporarily store its patient data for transfer to beside patient monitor 20 or defibrillator 30 the next time it is docked.

(25) Referring to FIGS. 3 and 4, wired communication between the modules may involve a direct electrical connection facilitated by a docking station. In practice, communication via direct electrical connection generally works well with low power, low energy modules that have inherently high signal to noise ratios, such as, for example, patient monitors 20 and 40 when docked. However, defibrillator 30 provides electrical thearpy(ies) that may generate significant noise that disturbs the direct electrical connection between defibrillator 30 and monitor 40 when docked. Furthermore, a direct electrical connection experiences wear and tear faster than other forms of communication that do not require a mechanical interface.

(26) Alternatives to a direct electrical connection are a wireless data link and an optical data link, particularly for defibrillator 30 and monitor 40. Generally, the wireless data links use circuitry that drive antennas to transmit and receive RF energy via one or more standard protocols, and the optical data links use light sources for sensing transmitted light.

(27) Specifically, referring to FIGS. 5 and 6, monitor 40 is shown equipped with an antenna 46 and defibrillator 30 is shown equipped with an antenna 36. In practice, controllers 33 and 43 implement one of a wide variety of wireless communication modalities and standards that allow electrically isolated communication through free space via RF energy including, but not limited to, WiFi, WiMax, Bluetooth, 3G, NFC, Zigbee, GSM and Wireless USB/Ultraband. This wireless data link is most appropriate when monitor 40 and defibrillator 30 are undocked.

(28) Referring to FIG. 5, monitor 40 is shown equipped with a light emitting diode (“LED”) 47 and defibrillator 30 is shown equipped with a photo-sensor 37. In operation, transceiver windows 48 and 38 are aligned whereby LED 47 and photo-sensor 37 are aligned whereby controller 43 energizes LED 47 to emit photons to excite photo-sensor 37 which is detected by controller 33. This optical data link is most appropriate when monitor 40 and defibrillator 30 are close, docked or undocked.

(29) Alternatively for docking purposes, referring to FIG. 6, therapy docking station 60 may be equipped with a LED 62 and a photo-sensor 63 to establish the optical data link between monitor 40 and defibrillator 30. As with the embodiment of FIG. 5, using light to transmit data across the physical interface between monitor 40 and defibrillator 30 eliminates the need for wires, cables and connectors that may be subject to the wear and tear of micro-vibration.

(30) In practice, the optical data links will typically be bi-directional (e.g., defibrillator 30 being equipped with a LED and monitor 40 being equipped with a photo-sensor). Furthermore, the wireless data link and optical data links illustrated in FIGS. 5 and 6 are applicable to any modular embodiment of the present invention.

(31) Alternatively, transformers may be utilized for close data links.

(32) Referring to FIGS. 2-6, those having ordinary skill in the art will further appreciate numerous benefits of the present invention including, but not limited to, an elimination of a need to detach and reattach patient leads and avoidance of a discontinuity in monitoring the patient when there are no leads attached.
