  • Patent number: 5727559
    Abstract: The vascular resistance to blood flow through the hand is increased in an essentially uniform manner by the application of pressure to the hand. The pressure is applied by means of an inflatable bladder mounted on an arm board or within a non-expandable sleeve, mitten or glove, which bladder covers at least the palm of the hand. Controlled inflation of the bladder conveys pressure to the hand tissue to a degree necessary to compress vascular structures and obstruct or restrict blood flow. By occluding blood flow through the hand, more accurate invasive blood pressure readings can be taken in clinical situations where decreased hand vascular resistance occurs.

  • Patent number: 5588956
    Abstract: The invention is directed toward providing a method and a brace for supporting a knee joint to permit movement of the joint in first selected directions and to restrain movement in second selected directions. The brace comprises a flexible sheet and at least two enclosed inflatable chambers contained in the flexible sheet. The chamber is formed of a material which is light and flexible when uninflated but is relatively rigid when inflated. Each inflated chamber follows a path corresponding to that of one of the cruciate ligaments and together they support the joint and prevent unwanted movement of the portion to be restrained from movement. However, the material has sufficient flexibility and when coupled with the flexible sheet serves to prevent abrasion of the sensitive areas of the joint being confined. The flexible sheet, while very flexible, also protects against the transmission of shock to the joint.

  • Patent number: 5514079
    Abstract: The present invention provides a method and apparatus for improving the circulation of blood through a patient's heart and extremity. The method comprises applying external positive regional pressure on an extremity synchronously with the patient's heartbeat. An adjustable timing cycle is initiated at the QRS complex of the arterial pulse cycle. The timing cycle is based on an average time period between QRS complexes, which is calculated from a measurement of several successive QRS complexes in the patient's heart rate. Pressure pulses are applied in the end-diastolic portion of the arterial pulse cycle to reinforce the pulse that forces blood into the extremity. The pressure is then relieved prior to the next projected QRS complex to enable the next pulse to enter the extremity without undue obstruction, thereby promoting circulation of blood through the extremity. To promote circulation of blood through the heart, compression of the extremity is released shortly before the next projected QRS complex.

  • Patent number: 5378224
    Abstract: The invention is directed toward providing a method and a brace for supporting a joint of the body to permit movement of the joint in a first selected direction and to restrain movement in a second selected direction. The brace comprises a flexible sheet and an enclosed inflatable chamber contained in the flexible sheet. The chamber is formed of a material which is light and flexible when uninflated but is relatively rigid when inflated. The inflated chamber supports the joint and prevents unwanted movement of the portion to be restrained from movement. However, the material has sufficient flexibility and when coupled with the flexible sheet serves to prevent abrasion of the sensitive areas of the joint being confined. The flexible sheet, while very flexible, also protects the transmission of shock to the joint.

  • Patent number: 5311882
    Abstract: A head restraint for immobilizing a patient during tomographic examination. A two part cover, each part enclosing a pneumatic, inflatable member, is adjustably assembled so as to locate each inflatable member on opposite sides of the patient's head. A strap encircles the forehead, maintaining the restraint on the patient. A hand held squeeze bulb simultaneously and equally pressurizes both inflatable members so as to occupy all space between the patient's head and a U-shaped head holder typically provided with tomography X-ray machines. The inflatable members establish a comfortably fitting, flexible, large patch of contact with the patient's head and with the head holder. These characteristics immobilize a patient's head sufficiently to enable clear images to be developed. The inflated members are depressurized by a manual valve, and the restraint is readily removed from the patient.

  • Patent number: 5289828
    Abstract: An abduction pillow used to immobilize a patient's legs after hip surgery has a wedge-shaped body constructed of a resilient deformable material which positions the legs in a forgiving, fixed divergent position. The body is wedge-shaped and preferably air filled, and has a pair of opposing sides which taper outwardly in a divergent manner from a narrow anterior end adapted to be located adjacent the groin area of a patient, toward a wider distal end. The body has an upper surface which inclines downwardly from the distal end toward the anterior end. A longitudinal arcuate recess is formed in the upper inclined surface and has a depth sufficient to support one of the patient's legs. The vertical distance between a plane in which the other of the patient's legs lies and the bottom of the longitudinal arcuate recess, is equal to the width of the wedge-shaped body at any transverse plane taken through the pillow.

  • Patent number: 5279283
    Abstract: The present invention provides a method and apparatus for improving the circulation of blood through a patient's heart and extremity. The method comprises applying external positive regional pressure on an extremity synchronously with the patient's heartbeat. An adjustable timing cycle is initiated at the QRS complex of the arterial pulse cycle. The timing cycle is based on an average time period between QRS complexes, which is calculated from a measurement of several successive QRS complexes in the patient's heart rate. Pressure pulses are applied in the end-diastolic portion of the arterial pulse cycle to reinforce the pulse that forces blood into the extremity. The pressure is then relieved prior to the next projected QRS complex to enable the next pulse to enter the extremity without undue obstruction, thereby promoting circulation of blood through the extremity.
