The utility of pulse volume measurement is expanded to detection of many conditions which have previously not been detected or have been detected using more complicated techniques. Such conditions include blood loss, septic shock, cardiogenic shock, neonatal sepsis, patent ductus arteriosus, limb ischemia, intra-aortic balloon pump performance, peripheral vascular disease, congestive heart failure, the effectiveness of vasoactive medications, syncope, dehydration, pre-eclampsia, deep vein thrombosis, thermal injuries, vascular instability due to renal dialysis, compromising of circulation to the hand caused by radial artery harvesting, changes in cardiac output, and hypertension. According to the present invention, such diagnoses can be performed by taking one measurement, by taking measurements over time to detect a change or by taking measurements before and after application of a treatment or stimulus.

A safety hypodermic needle and a method of using the same are disclosed. The safety needle comprises a hypodermic needle and a protective sheath molded of a flexible polymeric material. The protective sheath comprises a needle sleeve with an open central passage which houses the sharp needle point. The needle sleeve is supported on a plurality of inwardly bowed ribs in an unflexed “at rest” condition in which the needle point is retained inside the needle sleeve to prevent inadvertent needle sticks. Levers attached to the ribs are used to move the ribs from their inwardly bowed unflexed “at rest” condition to an outwardly bowed flexed condition to permit the needle to pass through the open central passage of the needle sleeve and into a patient's body. After the needle is removed from the patient's body, the ribs automatically return to the unflexed “at rest” condition without the assistance of any additional biasing or restoring means.

Improvements in a safety hypodermic needle and a method of making the same are disclosed. The improvements relate to a commercial embodiment of a patented safety needle and comprise a tubular member extruded from a flexible elastomeric or rubber-like polymeric material. The tubular member is extruded with two ribs extending from the outer wall of the tubular member and spaced apart 90° circumferentially. The wall of the tubular member is provided with through cuts to form a cutout on one wall portion and an elongated lever on the opposite wall portion in the 90° space between the ribs. The cuts separate the wall of the tubular member into two outwardly flexible arms, each having a single rib thereon adjacent an edge of the arm. One end of the tubular member is stretched over the needle hub of a hypodermic needle and the other end is stretched over a needle cup which houses the sharp needle point. The needle cup is provided with a needle opening through which the needle extends during use.

A patient's peripheral pulse volume and blood pressure are measured. The quantities are used to obtain a quantitative measure of peripheral vascular function. The quantitative measure can be one or more of pulsatile limb blood flow, total limb blood flow, limb vascular compliance and limb vascular resistance.

This device uses electrical impedance and signal processing to measure the small change in volume (“Pulse Volume”) of a limb-segment that occurs with each heartbeat. “Pulsatile Flow” is defined as the pulse volume multiplied by the heart rate and is an index of tissue perfusion. This information can be combined with measured blood oxygen saturation to determine how much oxygen is reaching the tissues. The combination of knowing oxygen saturation and tissue perfusion is far more useful than knowing just one or the other of these parameters.

A multiple blood pressure cuff system comprises a plurality of inflatable cuffs of a range of widths and lengths which collectively share a common pressure source and a common pressure measuring device. A manifold pneumatically connects each cuff to the common pressure source and pressure measuring device and stopcock valves allow airflow to be directed to only the particular cuff in use. A mounting board is provided for affixing the system to a wall or cabinet and for conveniently supporting and displaying the cuffs that are not in use.

A plethysmographic or other signal is autocorrelated to give a first-pass determination of the distances among individual waveforms. A waveform is isolated, tested to determine whether its amplitude remains in suitable bounds for signal averaging, and convolved with the signal to match it with the other waveforms for averaging. Thus, a separate gating signal is not needed for signal averaging.

A footwear fastening system and a method of converting lace fastened footwear to hook-and-loop fastened footwear comprising hook-and-loop fastener strips which are secured to the footwear by means of a lace which passes through adjacent eyelets along each upper side of the footwear. The fastener strips are anchored to one upper side with the lace and are passed beneath the lace on the other upper side and tensioned to draw the upper sides together into a snug fit. Tubular posts may be disposed between the eyelets and laced to the upper sides by the lace.
