Abstract:
The apparatus is arranged to supply a flow of substantially pure oxygen to a person, and comprises a source of substantially pure oxygen gas, means for release of the substantially pure oxygen gas from the source into an ambient atmosphere; and means for cooling the substantially pure oxygen gas released from the source to a temperature below that of the ambient atmosphere. The substantially pure oxygen gas when cooled by the cooling means can be allowed to sink under ambient pressure by convection into a zone including the ambient atmosphere, the zone being beneath, and in convective communication with, the cooled substantially pure oxygen gas, whereby the cooled and sunken substantially pure oxygen gas can come into contact with the skin of a person in that zone. At least one parameter (such as temperature, oxygen concentration, sound or vibration) is monitored in the zone and operation of the release means is only permitted when the parameter is in a predetermined range.
Abstract:
A pneumatic device for cardiopulmonary resuscitation assist includes a back plate and a compressing member. The back plate has two securing members mounted respectively on two sides of the back plate. The compressing member includes a mounting plate and a bladder. The mounting plate is detachably connected to the back plate and has an upper surface, a lower surface, a gas passage and two securing straps. The gas passage is formed on the upper surface of the mounting plate. The securing straps are respectively mounted on two sides of the mounting plate and respectively connected selectively to the securing members. The bladder is mounted on the lower surface of the mounting plate and communicates with the gas passage. The bladder can compress a patient's chest continuously and stably when repeatedly inflating the bladder, and this provides a good cardiac massage and prevents hurting the patient's ribs.
Abstract:
Apparatus for automatic delivery of chest compressions and ventilation to a patient, the apparatus including: a chest compressing device configured to deliver compression phases during which pressure is applied to compress the chest and decompression phases during which approximately zero pressure is applied to the chest a ventilator configured to deliver positive, negative, or approximately zero pressure to the airway; control circuitry and processor, wherein the circuitry and processor are configured to cause the chest compressing device to repeatedly deliver a set containing a plurality of systolic flow cycles, each systolic flow cycle comprising a systolic decompression phase and a systolic compression phase, and at least one diastolic flow cycle interspersed between sets of systolic flow cycles, each diastolic flow cycle comprising a diastolic decompression phase and a diastolic compression phase, wherein the diastolic decompression phase is substantially longer than the systolic decompression phase.
Abstract:
Improved procedures for cardiopulmonary resuscitation of a victim of cardiac arrest are provided. In the resuscitation the victim chest is mechanical compressed and decompressed to stimulate the heart. The victim is induced to inspire and expire against insufflating breathing gas during the chest compression/decompressions. The breathing gases are adduced under pressure to promote the development of a positive coronary perfusion pressure. Electro-stimulation of the heart can be carried after positive coronary perfusion pressures have been achieved. The electro-stimulation can be defibrillation or heart pacing or both. The chest compression/decompression cycles and the electro-stimulation measures are synchronized to promote sufficiently body circulation of oxygenated blood in a subject suffering from cardiac arrest. Medical equipment systems are provided for implementing the CPR procedures.
Abstract:
A walker for providing a patient having a breathing disorder the ability to carry an oxygen bottle safely upon the walker. The walker has a pair of side frames having front vertical bars that are connected by a pair of cross members. Wheels are attached to the front bars of the frame for propelling the walker. An open top canvas bag containing the oxygen bottle is suspended from the top cross member so that the center of gravity of the bottle lies in a common vertical plane with the wheel axis and is centered between the frames. Stabilizers are provided to prevent the bottle from moving side to side or out of the frame.
Abstract:
A rotary apparatus gives a patient a rotational motion at a discretionary controlled speed suitable to medical treatment and at the same time can continuously supply the patient in rotation with oxygen for inhalation by means of oxygen supply equipment. The apparatus is characterized in that a chair 1 on which a patient is sitting is driven, via a rotary shaft 6, by a driving system 3 installed in a control base 2 to rotate, and oxygen for inhalation to be supplied to the patient in rotation is guided to pass through the interior of the rotary shaft 6 and supplied by a mouthpiece 23 provided at the top end of an oxygen supply tube 21 to a position suitable for the patient to breathe.
Abstract:
A cardiopulmonary resuscitation, CPR, device (100, 200, 400) for delivering intrathoracic pressure pulses to a subject (290), the device comprising an air pressure generator (110, 310, 410) for delivering air to the airways of the subject (290), wherein the air pressure generator (110, 310, 410) is configured to: operate a first mode, wherein in the first mode the air pressure generator (110, 310, 410) generates a first output (412, 770a, 770b) comprising a first plurality of positive pressure pulses (771) for temporally increasing the subject's intrathoracic pressure to induce compressions of the heart of the subject (290) by increasing the volume of the subject's lungs; operate a second mode, wherein in the second mode the air pressure generator (110, 310, 410) generates a second output (414, 880) comprising a second plurality of positive pressure pulses for providing an assured airflow to the lungs of the subject (290); and deliver a resulting output (425, 986, 1086) to the airways of the subject (290), the resulting output being the superposition of the first output (412, 770a, 770b) and of the second output (414, 880); wherein said first plurality of positive pressure pulses (771) have an amplitude greater than 30 mbar and a frequency in a range of 40-240 beats per minute; and wherein said second plurality of positive pressure pulses have an amplitude smaller than 30 mbar and a frequency in a range of 3 to 20 cycles per minute.
