Abstract:
A fluid dispersion and delivery assembly (49) includes first and second syringes (28, 50) containing a hemostatic solution (38) and a flowable gel material (58), fluidly coupled together by a fluid transfer assembly (2). The fluid transfer assembly includes a double Luer fitting (4) and a hollow tube (6), having openings (24, 22) at its ends (16, 18), reciprocally mounted within the fitting. This permits the hemostatic solution in the first syringe to be evenly dispersed into the flowable gel material within the second syringe by simply pressing the plunger (46) of the first syringe. After dispersion, the fluid transfer assembly is dismounted from the second syringe to permit combined material (62) within the second syringe to be dispensed.

Abstract:
An agitator (1) is for a liquid analysis system (3, 50). It has a chamber (5) for reception of a sample liquid. A passageway (6) from the bottom of the chamber (5) ends in an agitator chamber (7). A side wall of the agitator chamber (7) is formed by a diaphragm (8). The diaphragm (8) is connected to an electric motor (9) with an eccentric drive for reciprocating movement of the diaphragm (8). A gas inlet (10) in the opposite side of the body (2) is connected by a passageway (11) to the agitator chamber (7). The agitation chamber has a domed internal face opposed to the diaphragm, by which about 10% of the agitation chamber (7) volume is displaced by the inward movement of the diaphragm (8). Also, advantageously, there is a uniform application of displacement force within the agitation chamber (7) by virtue of the domed internal surface.
Abstract:
A syringe-to-syringe mixing apparatus comprises first and second syringes adapted to be coupled at their respective outlets to fluidly connect the syringes. The first syringe includes a plunger having a hollow plunger barrel and a distal end defining a lumen therethrough. The lumen is initially closed by a septum, which in one embodiment is an elastomeric stopper mounted over the end of the plunger. The mixing apparatus further includes a third syringe slidably disposed within the plunger barrel. The third syringe includes a hollow needle adapted to pierce the septum to allow fluid from the third syringe to be injected into fluid within the coupled first and second syringes.
Abstract:
A fibrin wound dressing is made by mixing quantities of fibrinogen solution and thrombin solution with air. The resulting foam is very light weight, and with the proper attention to the amount of thrombin, will rest on a vertical surface without dripping. The wound dressing may also be formulated for its ability to continue migration of healing substances, such as PDGF, from the dressing to the wound site. Thrombin substitutes, such as other clotting proteins, may be used instead of thrombin. The resulting foam may also be lyophilized or ground and lyophilized for later reconstitution. A therapeutic drug or other additive may also be added to the wound dressing. A fibrin foam may be made by injecting fibrinogen foam into a clotting protein, such as thrombin.

Abstract:
Mélangeur modulable (1) composé d'un module d'alimentation (2) permettant l'introduction des matières à mélanger dans le dispositif et d'un ou plusieurs modules de mélange (3) réalisant une homogénéisation des matières en les forçant d'un compartiment (11, 12) d'une chambre de mélange (26) à un autre à travers une grille de mélange (10) au moyen de deux pistons colinéaires (7) coulissants dans cette chambre. Les différents modules, composés d'éléments similaires, sont reliés selon les besoins de l'utilisateur par des unités de jonction (4) permettant le transfert de matière d'un module à un autre, l'introduction de matière, une sortie de matière ou un prélèvement en ligne au cours d'un transfert de matière entre deux modules. Ces unités de jonction sont instrumentées afin d'effectuer diverses mesures de contrôle et de caractérisation du mélange. Cette invention intéresse les laboratoires, les centres de recherche et les petites unités pour la production de produits qui résultent d'un ou de plusieurs mélanges de produits visqueux.
Abstract:
Embodiments disclosed herein provide a pump or a multiple-pump system that can mix chemicals without dilution tanks and can dispense the mixture of chemicals in a precise and highly controllable manner, particularly useful in semiconductor manufacturing processes. In some embodiments, one or more piston pumps of similar displacement are used to mix and dispense the chemical directly. A first valve is opened to a first chemical source. A piston is moved in a first direction to a selected position in a chamber to draw the first chemical into the chamber. The first valve is closed and a second valve is opened to a second chemical source. The piston is moved in the first direction to a second position in the chamber to draw in the second chemical and mix the chemicals. The second valve is closed and the piston is moved to dispense the fluids through a dispense port.
