  • Publication number: 20230321433
    Abstract: A patient monitoring system within an Electroconvulsive Therapy (ECT) device includes a patient monitoring channel including a first electrode and a second electrode, with each electrode coupled to a respective lead. The monitoring system also includes an Alternating Current source structured to inject a test current to the first electrode lead or the second electrode lead and a differential amplifier structured to measure differences between signals received from the first electrode lead and the second electrode lead. Related methods include evaluating a quality of an electrode contact with a skin surface by injecting a lead of the electrode and one input of a differential amplifier with a known electrical current, comparing a difference between an electrical signal received from the lead of the injected electrode as well as from a lead of a passive signal electrode, and evaluating the compared difference.

  • Patent number: 6014587
    Abstract: An electro-convulsive therapy (ECT) system includes both hardware and software safety detectors and monitors generator that generates a pulse train of a plurality of pulses with parameters specified by the user. The safety monitors monitor these user-specified parameters as well as other important pulse parameters both during treatment of a patient and prior to treatment in order to ensure that the system is operating according to specification and, therefore, will not injure the patient. The pulse generator is responsive to the safety monitors in that if any of the safety detectors detect a parameter that is out of tolerance, the safety monitor disables the pulse generator so that no further pulses are delivered to the patient. The safety detectors detect the plurality of pulse characteristics including pulse width, frequency, voltage, current, treatment duration, as well as energy.

  • Patent number: 5950627
    Abstract: A spine board having internal stiffening elements mechanically connected to an outer shell via a number of speed pins. A quantity of urethane foam fills the spaces between the stiffening elements and the shell. The speed pins permit the rotational molding of the shell about a pair of graphite reinforcing tubes, which better distributes the loads to be born among the outer shell, urethane filler, and stiffening elements, thereby increasing the life span of the board.

  • Patent number: 5545174
    Abstract: A lancet type device having a movable and retractable lancet tip is disclosed. The lancet tip extends beyond the end of a lancet body. The device includes an actuating mechanism that moves and retracts the sharp distal lancet tip linearly into and out of contact with a patient's skin. The actuating mechanism includes an arm with a substantially "V" shaped groove. In one embodiment, the arm extends away from and pivots around the proximal end of the device. In another embodiment, the arm moves transversely across the device. A cylindrical cam follower protrudes from the lancet body. Contact between the groove and the cam follower moves the cam follower, and consequently the lancet body, in a linear direction along the axis of the lancet body.
