Definitions

  • the present disclosure relates generally to biological and/or synthetic fluid applicators and, more particularly, to dispenser manifolds and related applicators for mixing and dispensing components of biologically compatible tissue adhesives, synthetic sealants and/or hemostats.
  • Biologically derived as well as synthetic sealants, hemostats and/or adhesives are used to treat wounds in instances where external dressings or sutures are not totally effective.
  • a common treatment takes advantage of the rapid reaction which occurs when a solution of clotting factors, such as fibrinogen, comes into contact with a solution of a catalyst, such as thrombin, to form a complex which acts as a tissue adhesive.
  • This rapid reaction typically commences within 2 seconds after the solutions initially contact one another, and it typically attains a soft set within 10 seconds of contact.
  • a common name for such a complex is fibrin glue.
  • Prior fibrin glue delivery systems may generally be categorized as utilizing either turbulence within a solution or overlapping contact of airborne sprays to obtain mixing.
  • the apparatus utilized by either of these systems typically includes confining a fibrinogen solution separately from a thrombin solution, then permitting these two solutions to mix either immediately prior to or upon application on a wound. Typically, these solutions are confined within separate syringes prior to mixing.
  • the present disclosure provides a manifold assembly including a disposable integral mixing and dispensing chamber, disposed in direct contact with the component reservoirs as a replaceable element.
  • the disposable mixing and dispensing chamber are disposed within a cavity of the manifold in fluid communication with the two component reservoirs.
  • an atomizer structure is alternatively provided for converting the mixed adhesive into a spray.
  • the mixing and dispensing chamber can be made in a variety of configurations and lengths to facilitate remote application of mixed adhesive such as, e.g. in endoscopic or laparoscopic procedures.
  • a self contained magazine of integral mixing and dispensing chamber may be provided in a configuration wherein a series of new integral mixing and dispensing chamber is sequentially advanced into alignment with the flow path as directed by the user.
  • FIG. 1 is a side view in cross section illustrating an elongated manifold in accordance with one embodiment of the present disclosure
  • FIG. la is a side view in partial cross section of an integral mixing and dispensing chamber to fit within and for using with the manifold of FIG. 1;

  • FIG. 7 is a side view of a magazine loaded with multiple integral mixing and dispensing chamber; and FIG. 8 is a side of the dispenser of FIG. 6 with the magazine of FIG. 7 connected thereon.
  • the manifold assembly 50 includes a manifold 10 and a disposable mixing and dispensing chamber 20.
  • Manifold 10 includes a manifold base 52 and a guide 54 detachably connected thereon. At a proximal end of the manifold
  • two conduits 56, 58 separately convey the adhesive components from their respective reservoirs (not shown) to a cavity 66 formed in the manifold 10.
  • the proximal end of the manifold 10 may further include connections 60, 62 in fluid communication with the respective conduits 56, 58 for facilitate connection to the reservoirs.

  • the two separate components are fed into the mixing chamber portion 70 of the mixing and dispensing chamber 20 where they are mixed thoroughly.
  • a baffle structure 72 of known type may be placed within the mixing chamber portion 70 to facilitate the mixing.
  • the mixed adhesive is conveyed down the dispensing conduit portion 74 under pressure and is expelled out the distal end of the manifold 50.
  • the distal end of the manifold may be equipped with an outlet port or orifice 76 for affecting the dispensing of the adhesive.
  • the distal end may incorporate a spray head or a drip type structure.
  • FIG. 3 illustrates another embodiment of the present invention, which is similar in structure except the distal portions of the manifold 10 and the mixing and dispensing chamber 20 of FIGS. 1-2.
  • Manifold guide 78 is configured in a shorter length than the manifold guide 54 described herein above.
  • a distal portion of the mixing and dispensing chamber 80 protrudes out from the distal end of the guide 78.
  • An outlet port or spray nozzle 82 is disposed at the distal end of the mixing and dispensing chamber 80.
  • FIG. 4 illustrates a dispenser 100 including a component supply system of known type and incorporating a shorter manifold 84 configured and dimensioned to receive an integral mixing and dispensing chamber 88. This embodiment is substantially similar to the manifold assembly 50 of FIGS.
  • FIG. 7 illustrates a magazine 110 configured and dimensioned to sequentially hold a plurality of mixing and dispensing chambers 88. In a preferred embodiment, as depicted in FIG.
  • manifold 94 is configured to receive magazine 110 in a manner wherein the user can apply pressure to pusher 116 to advance a new mixing and dispensing chamber 88 into fluid communication with the component conduits while simultaneously ejecting the old mixing and dispensing chamber.
  • the magazine 110 includes a container 112 for receiving the plurality of mixing and dispensing chambers 88 therein and defines an opening 114 for taking the plurality of the mixing and dispensing chambers and advancing a new mixing and dispensing chamber into an opening 96 of the manifold 94.
  • manifold assembly including the mixing and dispensing chamber as described in various embodiments herein above. It is also envisioned that at least some portion of the manifold and/or mixing and dispensing chamber may be formed from transparent material to monitor clogging therein.

Abstract

L'invention concerne un ensemble collecteur (10) permettant de faciliter le mélange et la distribution d'un adhésif biologique multicomposant, qui comprend un collecteur (52) doté d'une pluralité de conduits d'entrée (56, 58) séparés, et définit une cavité (66) s'étendant de manière distale en communication fluidique avec ladite pluralité de conduits d'entrée (56, 58). L'ensemble collecteur (10) comprend également une chambre de mélange (54) jetable possédant au moins une partie (64) configurée et dimensionnée de façon à s'ajuster de manière amovible dans la cavité (66) du collecteur, et à être en communication fluidique avec la pluralité de conduits d'entrée (56, 58). Cet ensemble (10) peut comprendre une tête de pulvérisation ou un port de sortie (76, 82) disposé à l'extrémité distale dudit ensemble en communication fluidique avec la chambre de mélange (54), de façon à appliquer des adhésifs biologiques mélangés.
