An infusion pump for infusing a medical treatment fluid intravenously to a patient includes a collapsible treatment fluid bag juxtaposed with an inflatable drive fluid bladder confined between a pair of opposing containment members which cause the bladder to impinge against the bag as the bladder is inflated. A drive fluid pump controllably inflates the bladder, thereby displacing treatment fluid from the bag into an outlet tube affixed thereto which conveys the treatment fluid to the patient where it is received intravenously. The treatment fluid flow rate through the tube is controlled by increasing or decreasing the drive fluid pump output and consequently the pressure in the bladder in response to a pressure sensor in fluid communication with the bladder. Alternatively, the treatment fluid flow rate is adjusted by opening or closing the outlet tube by means of an occluder or restrictor positioned along the tube.

Infusion pump, treatment fluid bag therefor, and method for the use

An adjustable shoulder brace is provided for stabilizing and immobilizing the shoulder following an injury or surgical trauma to the soft tissue thereof. The shoulder brace is mountable on the arm and torso to isolate the shoulder and is fully adjustable across the abduction, flexion and rotation ranges of motion of the shoulder to enable fixation of the shoulder in virtually any rehabilitative position. The brace is made up of a series of rigid support members secured to the body of the patient, and a plurality of selectively rotatable and lockable joints adjustably interconnecting the support members. The combined effect of the joints simulates the entire range of motion of the shoulder.
