Abstract:
A device, system, and method for isolating a ventilator from one or more patients in which the delivery conditions of gas delivered to an isolation device from a ventilator may drive the delivery of breathing-gas delivered to one or more patients, the breathing-gas having the same or different delivery conditions. In one embodiment, an isolation device may have a housing and a movable partition. The movable partition may be joined to the housing, The movable partition may have a patient side on a first side of the partition and an actuating side on a second side of the partition. The isolation device may include an inlet pressure regulator on the actuating side and/or an exhaust pressure regulator on the patient side. These regulators may alter the delivery conditions (including, but not limited to, pressure and volume) of breathing-gas delivered to a patient.
Abstract:
A therapy system adapted to treat a patient's ventilatory instability using a ventilatory therapy, a gas modulation therapy, or both. The algorithm implemented by the therapy system monitors the ventilatory instability, such as Cheyne Stokes Respiration (CSR), mixed apneas, CPAP emergent apneas, and complex sleep disordered breathing (CSDB) and treats the ventilatory instability. The algorithm also determine a reference point with respect to the ventilatory instability. The therapy delivery system initiate the treatment based on the reference point.
Abstract:
The present invention pertains to a device and a process for determining the hygienic state of an accessory (1) for a medical basic device (3), in which temperature events of the accessory (1) corresponding to the exceeding of a preset temperature are stored with the corresponding times, the stored temperature events with the corresponding times are compared with comparison values for temperature and time, so that a display, output and/or alarm is brought about at the medical basic device (3) in case the temperature exceeds the comparison value for a preset total time or for a preset number of temperature events.
Abstract:
Isolation devices and methods of controlling a partition are disclosed. Devices according to the invention have a housing disposed about a movable partition. The housing has respirator and patient sides on respective first and second sides of the partition. The housing also has: (a) a respirator orifice on the respirator side, adaptable to be in pneumatic communication with a respirator; (b) a patient inspiration orifice on the patient side, adaptable to be in pneumatic communication with a patient; (c) a bias inflow orifice on the patient side, adaptable to be in pneumatic communication with a source of inspiratory gas; and, (d) an expiration return orifice on the patient side. The devices may further include a partition position sensor, a CO2 scrubber, and a controller operable to regulate gas flow to the bias inflow orifice based on partition position.
Abstract:
A manual inexsufflator including a standard mechanical ventilator, a medical suction unit, and a piston-like sliding valve mechanism which connects a patient ventilation interface with either the ventilator or the suction unit. By sliding the valve mechanism in and out the user selectively connects the patient to either the ventilator, for purposes of insufflation, or the suction unit, for purposes of exsufflation. The ventilator may generate expiratory positive airway pressure between inexsufflation cycles.
Abstract:
A gas-powered resuscitator is operable either in a manual mode or an automatic mode. The resuscitator includes an oscillatory timing valve (14) having an outlet (23) connected to a bi-stable valve (25), the operation of which is piloted by a manual valve (16). The outlet (26) of the bi-stable valve (25) connects to the outlet (2) of the resuscitator via a rotatable control (32) and a patient valve (41). The outlet (26) of the bi-stable valve (25) also connects to the control inlet (34) of the timing valve (14). The manual valve (16) has a button (62) that can be pushed down manually in the manual mode or can be held down in the automatic mode by rotating a locking ring (262). The maximum duration of cycles is limited by operation of the timing valve (14), whether the resuscitator is operated manually or automatically.
Abstract:
Described is a system and method which includes the following steps. A plurality of interventional agents are administered to a patient until the patient attains a predetermined plane of anesthesia. Brain waves of the patient are amplified and digitized before and after the administering step to generate a first set of digital data. The brain waves of the patient are amplified and digitized during a medical procedure to generate a second set of digital data. Separate trajectories for at least two different indices of an anesthetic state of the patient are computed during the medical procedure as a function of a comparison of the first and second sets of digital data. The indices include a Depth Index (DI), a Memory Index (MI) and a Pain Index (PI). The DI corresponds to a depth of anesthesia of the patient, the PI corresponds to a sensitivity of the patient to pain and the MI corresponds to an ability of the patient to form and store memories.
Abstract:
The ventilation interface for sleep apnea therapy interfaces a ventilation device to the patient's airways. The ventilation interface includes a pair of nasal inserts made from flexible, resilient silicone which are oval shaped in cross-section and slightly tapered from a base proximal the ventilation supply to the distal tip end. A bead flange is disposed about the exterior of each insert at the distal end of the insert. A bleed port for release of exhaled air is defined through a conical vent projecting normally to the path of the incoming air flow, and continues through a nipple extending to the exterior of the air conduit. In one embodiment, a pair of nasal inserts are integral with a nasal cannula body, with bleed ports axially aligned with each insert. In another embodiment, each insert is independently connected to a separate, thin-walled, flexible supply line.
Abstract:
Interface apparatus for use by a patient having a patient airway and for use with a mechanical ventilator having inspiratory and expiratory tubing. An intrapulmonary percussive ventilator having an output and an injection device coupled to the output of the intrapulmonary percussive ventilator and having an output. The interface apparatus comprises a mixing device having a mixing chamber therein and having an outlet adapted to be connected to the patient airway. The body has fittings in communication with the mixing chamber adapted to be connected to the inspiratory tubing and to the expiratory tubing of the mechanical ventilator. The body also has an injection port in communication with the mixing chamber adapted to be connected to the output of the injection device.
Abstract:
The invention relates to a device for washing the nasal cavities with a nebulized treatment liquid. It comprises a base body, a atomizer chamber containing a washing liquid, means for nebulizing the liquid in said chamber and dispensing the atomized liquid to the nasal cavities for washing and a chamber for collecting the return liquid and catarrhal matter from the nasal cavities. The atomizer chamber (12) and collection chamber (13) are positioned side by side above the base body, and the collection chamber communicates with a dispensing exit of the atomized liquid to the nasal cavities. The two chambers may be defined each by a respective element or by a single piece.
