Mixing and dispensing apparatus and methods for use with, e.g., a multi-component reactive material process is disclosed. In one embodiment, the apparatus comprises a series of positive displacement pumps adapted for stacked or “piggy-back” mating to a common motive source. At least one of the pumps is supplied by a sealed and collapsible reservoir bag and flexible tubing, thereby allowing removal (and optionally disposal) of one or more complete material pathways within the system. Such a configuration allows for, inter alia, rapid colorant changing with minimal material waste, obviates the use of hazardous solvents, and increases process efficiency and worker productivity. This arrangement also obviates complex metering apparatus common to prior art systems, thereby allowing it to be as small and power/cost efficient as possible.

A hand-held rebreather/breathing apparatus for high altitude pre-acclimatization and training. Air exhaled by a user is directed to a reservoir bag for cooling and condensate collection. At inhalation negative pressure created a mixing chamber forces the air stored in the reservoir bag to pass via CO2 absorption chamber where it may be mixed with a fresh portion of the ambient air that influxes via orifice(s) communicating with this chamber. Baseline of the minimum oxygen concentration in inspired air can be pre-set by means of adjustment of the maximum volume of the reservoir bag and/or by means of altering of the number or diameter of one or a plurality of orifices for commination of the ambient air. Biofeedback may be provided by an oxygen monitor.

A pulmonarily sized bag formed of a non-latex material, including a bag body formed of panels of resin film material welded to one another along a weld line defining a seam of the bag body bounding an interior volume of the bag. The seam includes an interior seam portion in the interior volume, and an exterior seam portion at an exterior surface of the bag. One of the interior seam portion and exterior seam portion comprises free edges of the seam, and the other one of such seam portions is devoid of free edges. The bag is formable by various techniques, including radio frequency welding, impulse heating, solvent bonding, etc., and is usefully employed in a breathing circuit to obviate the necessity of using latex breathing bags.

An ink delivery system for an ink cartridge comprises an ink reservoir bag of flexible, plastic sheet material, an ink cartridge and flexible tubing connecting the bag and cartridge in flow communication with one another. The bag is constructed of two sheets of plastic material having peripheral edges bonded together to provide an ink chamber therebetween and has separate fill and exit ports opening into the chamber and respectively defined by a fill tube and an exit tube bonded to the bag between the peripheral edges thereof. The flexible tubing is connected to the exit port through a check valve interposed between the port and tubing, and a lure lock is interconnected with the fill tube to provide an injection sight for filling the bag. The bag is enclosed in a container having openings through which the fill and exit ports extend. An ell fitting provides connection for the tubing to the top wall of the cartridge and clamping and strain relief arrangements are provided for respectively opening and closing the tubing to the flow of ink therethrough and removing the strain from the tubing at the connection to the cartridge.

A respiratory face mask is provided suitably sized and configured to engage at least the nose portion and mouth portion of a patient's face. Gas from a gas supply and scavenging set normally used in dentistry is operatively coupled to the mask via a breathing circuit to supply fresh gas and evacuate exhaled waste gas. A gas flow compensator in the breathing circuit automatically prevents re-breathing of exhaled gas. Because the mask has a sealing cushion, contamination of the clinical room where the apparatus is being used also is avoided. In an alternatively preferred embodiment, the fresh gas supply tube and the exhalation limb of the breathing circuit are replaced by a single length of co-axial flexible tubing connected between the face mask and a branched coupling. The branched coupling, in turn, includes a first branch for connection to the fresh gas supply nozzle of the “dental” set-up and a second branch for connection to a flexible flow-through reservoir bag used to store waste or exhaled gas. A one-way valve is disposed between the second branch output nozzle and the input of the flexible bag. The output of the flexible flow-through bag is connected to the vacuum module of the “dental” set-up. The second branch of the coupling, the one-way valve, and the flexible flow-through reservoir bag define the exhalation limb of the breathing circuit.

A disposable catamenial device for the collection of menses discharge of the female human, including: a flexible resilient menstrual cup (MC), which includes: at least two resilient ribs extending inwardly from the inner surface of the MC base; an elastic rim frame connected to the top of the ribs; a reservoir bag connected to the rim in a sealed manner for collecting the menstrual fluid; and a withdrawal string connected to the cup bottom for enabling the extraction of said MC from the vagina. The MC has a drogue like structure comprising at least two flexible ribs having arcuate vertical struts (AVS) structure connected to a flat base. The ribs are connected to the elastic rim frame with at least two flexible arcuate horizontal struts (AHS).

The present invention relates to a gas reservoir bag (6), comprising a flexible bag (9) for separating two different gases with a connection. The gas reservoir bag further comprises an outer bag (8) for generating a pressure difference between the flexible bag (9) and the ambiance of the outer bag (8), wherein the outer bag (8) surrounds the flexible bag (9) except for the connection thereof. The invention moreover relates to a distributor housing for a respiratory mask having such a gas reservoir bag and to a respiratory mask having such a distributor housing. The invention finally relates to corresponding methods.

A bag rack and packing system for a plastic grocery bag having a pair of handles has a base to which is connected (1) a three-sided rack having a reservoir bag holder for plastic bags and two arms and (2) a three-sided support having two side supports and an intermediate back support, with each of the side supports having a forward upper tab close to the three-sided rack, an intermediate top and then a rearward edge. The three-sided rack and three-sided support have open faces that face each other so that the three-sided support temporarily creates a defined physical frame for a first plastic grocery bag when its handles are secured over the forward upper tabs of the two side supports. The forward upper tabs help separate an individual bag from a reservoir of bags and the individual bag may remain attached to, or be detached from, the reservoir of bags as it is being filled.

The mask has an edge on the face cup that provides a larger sealing area for the users face and provides a more comfortable fit than existing masks. The mask may be configured as a simple constant flow mask or it may include valves, allowing it to function as a phase dilution mask. The mask may be equipped with a rebreather bag and valves to function as a rebreather/phase dilution mask

The present invention provides for a closed circuit breathing unit comprising a reservoir bag, oxygen source, CO₂ scrubber, and actuation device. The oxygen source and an exit from the scrubber may be fluidly connected to the reservoir bag. The reservoir bag may be attached to a mouthpiece to provide inhalation air. Expired air may be exhaled through the mouthpiece and directed to an inlet for the scrubber. As a user breathes normally, expired air is scrubbed of excess CO₂, mixed with generated oxygen, and delivered to the user for inhalation within a closed circuit. Additionally, the oxygen source and the scrubber may be replaced and/or replenished without compromising or interrupting a breathing cycle.
