Abstract:
A patient support apparatus including a first patient support configured to be rotated about a longitudinal axis. The first patient support illustratively includes an inflatable bladder. A backboard may be removably coupled to the patient support apparatus and is configured to facilitate transport of a patient to and from the patient support apparatus.
Abstract:
A resuscitation device for automatic compression of a victim's chest using a compression belt which exerts force evenly over the entire thoracic cavity. The belt is constricted and relaxed through a motorized spool assembly that repeatedly tightens the belt and relaxes the belt to provide repeated and rapid chest compression.
Abstract:
An applicator for applying an external counterpulsation to a body portion is provided. The applicator including: an outer shell for covering the body portion, the outer shell having a length in a longitudinal direction and a circumference in a circumferential direction; a balloon disposed in the outer shell, pressurization of which applies an external pressure to the body portion; and at least one anti-deformation member for reducing an amount of deformation of the outer shell caused by the pressurization of the balloon.
Abstract:
Therapeutic devices that provide support or pressure to tissue. Devices contain a material that is capable of being contracted from its relaxed state to an evacuated state. The material applies pressure to the tissue of a patient when the material is in its relaxed state. Reduction of pressure by application of a vacuum results in a contracted state of the device, so that the device can be applied or delivered to a patient. Release of vacuum results in a return to the relaxed state, thus providing a maximum desirable pressure to tissue and avoiding the possibility of over-pressure which can result in tissue damage or necrosis.
Abstract:
The present invention provides a method for applying external counterpulsation to a patient, including detecting a blood-flow impedance signal, self-adaptive filter processing the detected blood-flow impedance signal, and adjusting inflation of an inflatable member based on the self-adaptive filter processing in order to optimize counterpulsation timing. The present invention further includes an external counterpulsation apparatus providing a high-frequency current source applied to the patient to produce an electrocardiographic signal and a blood flow impedance signal, as well as an amplifier-filter circuit to operably condition the electrocardiographic signal and a heart impedance signal amplifier receiving the blood flow impedance signal. A computer processes the signals and controls a fluid distribution device to distribute compressed fluid to a plurality of inflatable members based on said processed signals.
Abstract:
A method for detecting leakage in a pressurised medical appliance prior to normal operation, the system including an air compressor and an inflatable bag or bladder coupled to the air compressor through the intermediary of a fill valve allowing air to pass to the bladder and a vent valve for venting the system, the fill valve and the vent valve being selectively operable during said normal operation to deliver cyclical pulses of air to inflate and deflate the bladder, the detection method comprising a) opening the fill valve to vent the system to atmospheric pressure, b) closing the vent valve, c) pressurising the system by means of the air compressor to a pre-determined threshold value, d) monitoring the pressure gradient or rise over a period of time to said threshold value and e) comparing the pressure gradient over said period of time or at intervals of time within said period of time with a pre-specified pressure gradient indicative of system integrity whereby to determine the presence or otherwise of air leakage in the system.
Abstract:
A vest for a human body has an air core coupled to a pulsator operable to subject the vest to air pressure pulses which applies and releases pressure to the human body. The vest has a cover having a pocket accommodating the air core. The pulsator has diaphragms connected to a d.c. electric motor with a rotary to reciprocating motion transmitting mechanism operable to generate air pressure pulses which are transmitted to the air core which applies repetitive pressure pulses to the human body.
Abstract:
The present invention provides a high efficiency external counterpulsation apparatus having accurate and reliable timing of inflation and deflation and reduced temperature of the pressurized gas, such that the gas flow temperature of the inflatable devices is near to room temperature, as well as faster and more responsive inflation/deflation equipment. The external counterpulsation apparatus includes a plurality of inflatable devices received about the lower extremities of the patient, a source of compressed fluid in communication with said plurality of inflatable devices, and a fluid distribution assembly interconnecting said source of compressed fluid and said inflatable devices. The fluid distribution assembly includes a selectively operable inflation/deflation valve interconnected between each of said inflatable devices and said source of compressed fluid. The fluid distribution assembly separately operates each inflation/deflation valve to sequentially inflate and deflate each inflatable devices.

Abstract:
An inflatable vest design for cardiopulmonary resuscitation (CPR) and for cardiac assist. The vest may include a belt that wraps around the chest of a patient, and a removable bladder that is placed against the chest and held in place by the belt. The inflatable bladder expands radially to first conform to a patient's chest, and to apply circumferential pressure to the thorax of the patient. By cyclically inflating the bladder, the vest can be used in CPR and cardiac assist treatments. In addition, alternative vest designs are disclosed showing removable bladders. These vest improvements lower the energy consumption and make smaller and portable cardiopulmonary resuscitation systems more practical.
