A ventilator system has at least one ventilator unit and a number of docking stations is described. Each docking station is adapted to receive the ventilator unit and comprises a communication interface adapted to be connected to a matching interface on the ventilator unit when the ventilator unit is docked in the docking station. The docking stations are arranged at different treatment sites, and the ventilator unit can be moved between different docking stations when necessary without interrupting the treatment of a patient connected to the ventilator unit. The same ventilator unit can be used throughout a complete treatment of a patient without any need of disconnecting the patient during transports, etc.

Ventilator system for one or more treatment patients

In respiratory care with liquids, the patient is connected to a liquid apparatus and a ventilator for supplying and removing a treatment liquid and a breathing gas respectively to/from the patient. The exchange of gases between the breathing gas and the treatment liquid is improved with a device which causes the breathing gas and/or the liquid to oscillate. The device may be a breathing gas generator which generates different frequencies to cause the breathing gas and treatment liquid to oscillate at appropriate frequencies. The device may be a vibrator unit which is applied to the chest to cause the treatment liquid to oscillate. The device may be a magnetic field generator for generating a magnetic field across the lungs and setting electrically conductive components in the treatment liquid in motion.

A portable respiration apparatus is dimensioned to convey a flow of gas, with an upper limit on pressure, from an inlet to an outlet connected to a patient. The inlet of the portable respiration apparatus can be connected to a stationary gas unit when a higher pressure is desired. The stationary gas unit can generate a gas pressure that is applied to the inlet of the portable respiration apparatus, so that a higher gas pressure can be generated and delivered to the patient. Alternatively, the stationary gas unit can be dimensioned so that it is itself capable of generating the desired gas pressure to be supplied to the patient, so there is no additional increase in gas pressure in the portable respiration apparatus.

Portable respiration apparatus, and system employing same

A heart stimulator, with verification of capture in the atrium of a heart, contains an atrial pulse generator which, via an atrial electrode, emits stimulation pulses in the atrium and a ventricular detector which senses depolarization signals in the ventricle via a ventricular electrode. The time which elapses between two consecutive stimulation pulses emitted in the atrium can be varied, and variation in ventricular events associated with the stimulation pulses is studied. If the ventricular events vary in time in the same way stimulation pulses emitted in the atrium vary, AV conduction is functional, and capture is present in the atrium.

Cardiac stimulator with atrial capture verification

A ventilator system and a tracheal tube, inserted into a patient's trachea to carry gas to and from the lungs, permit a gas mixture containing endogenous NO, which is present in the upper respiratory tract, to be supplied to the lungs. The tracheal tube has a input port which forms a connection between the interior of the tracheal tube and the upper respiratory tract. The input port draws or forces an amount of the gas containing endogenous NO into the tracheal tube and this gas accompanies the respiratory gas into the lungs during inspiration.

Tracheal tube and ventilator system permitting endogenously-produced NO

A device for indicating that an electrode cable is correctly connected to a medical implant for emitting electrical pulses, the implant being equipped with a connection part for the electrode cable's proximal end, has a contact for making electrical connection with the proximal end of the electrode cable and an indicator, the contact electrically causing the indicator to emit at least one indication signal which is perceptible outside of the implant when the electrode cable is correctly attached to the implant.

Connection indicator for medical device

An implantable heart defibrillator contains a pulse generator controlled by a control unit for emitting a number of heart stimulation pulses at a rate of several Hertz or more. The control unit causes the pulse generator to emit heart stimulation pulses with an energy content of the same, or somewhat greater, magnitude than conventional pacemaker pulses for a period of time long enough for the entire heart to become refractory.

Heart defibrillator and defibrillation method wherein defibrillation is

An electrode apparatus, such as an intravascular or intracardiac pacemaker or defibrillation electrode with an electrode cable has a jacket of insulation enclosing a first elongated, flexible conductor, connected to a first electrode arranged on the electrode cable, and also enclosing at least a second conductor, connected to a conductive surface forming a second electrode arranged on the electrode cable at a distance from the first electrode. In order to achieve an electrode apparatus with which the distance between the electrode on the electrode cable cart be changed in a very simple manner and in which the surface area exposed to tissue of at least one electrode can be enlarged, reduced and even rotated around the electrode cable in certain instances, the electrode apparatus is equipped with at least one sleeve-like body, insulated against the surroundings and slidable on the electrode cable, which at least partially covers the conductive surface and with which the second electrode can be formed whose position in relation to the first electrode and/or whose size can be varied.

Medical electrode system having a sleeve body and control element

An electrode device, for intracardiac stimulation and/or defibrillation of heart tissue and/or sensing heart signals in a patient, has a soft, flexible electrode cable with an outer coating of insulation containing at least one elongate conductor connected to an electrode arranged on the electrode cable. In order to attain an electrode device of this kind which is structurally very simple and in which all the electrodes on the electrode cable can be applied to the heart wall in a very simple manner so the entire electrode surface faces the wall and firmly presses against it, the electrode cable is at least partially ribbon-shaped.
