Abstract: A small manually operable pump which may be of the squeeze-bulb type, arranged to reduce fluid pressure and receive a fluid at a first end and to discharge a flow from an opposite end, and provided with a connector at each end so that it can be connected to various articles of emergency medical equipment to provide increased pressure or suction as required. A collection bag is arranged to use both the suction and the pressurized flow of the pump to suck materials from a wound or a patient's airway into the collection bag.

Abstract: A medical device including a portion similar to a Veress needle, useful for relief of tension pneumothorax. The device includes a hollow tubular stylet disposed movably within a hollow needle or cutting cannula, and an optionally releasable locking mechanism for keeping the stylet in place protruding distally beyond the sharpened distal end of the cutting cannula to prevent puncture of internal organs after the chest wall has been intentionally punctured. The stylet can also be moved outward from within the cannula to push a plug of tissue from the bore of the cannula. A valve or a connector for a tube may be provided at a proximal end of the stylet.

Abstract: A method and apparatus for assembling a spool valve into a valve bore of a body by providing compressed gas to the valve bore at a pressure below the pressure of compressed gas supplied to a passage within a carrier body containing a spool valve substantially concentrically aligned with the valve bore to advance the spool valve from the passage into the valve bore. The compressed gas in the passage provides a force acting generally uniformly on the spool valve substantially concentrically aligning the spool valve within the passage. The compressed gas supplied to the valve bore also acts substantially uniformly on the spool valve tending to substantially concentrically align the spool valve within the valve bore when the spool valve is advanced therein. While the gas in the passage and the valve bore align the spool valve, the higher pressure of the gas in the passage advances the spool valve into the valve bore.
