Abstract: A chair with a transom, a seat support, a back portion, and a combined rock and recline mechanism. The combined rock and recline mechanism has front and rear rocking arrangements configured to enable the seat support and back portion to together rock generally forward and rearward from a neutral position relative to the transom, and a recline arrangement that is configured such that the seat support is in a first at-rest position relative to the back portion when the back portion is in an upright position, and such that reclining the back portion rearwardly from the upright position toward a reclined position moves the seat support upward and rearward from the first at-rest position.

Abstract: A disposable tourniquet having a plastic strap and a windowed plastic pad defining a pair of liquid storage reservoirs mutually separated by a frangible wall. Bending of the pad breaks the frangible wall, comingling liquid solutions of water and hydrochloric acid and causing exothermic reaction heating on the order of 105-107 degrees F. When the pad is forcibly secured by the strap in contact with a patient's skin and with a portion of the patient's blood vessel lying within the window of the pad, then the skin is mechanically puffed up through the window and the blood vessel is mechanically stabilized. The blood vessel is simultaneously locally vasodilated. After venipuncture of the dilated vein through the window, the pad body is severable by a ripcord for quick removal from the venipuncture site.
