This application claims the benefit under 35 U.S.C. §119(e) of U.S. Non-Provisional application Ser. No. 12/258,076 filed on Oct. 24, 2008, and Provisional Application No. 61/887,359 filed on Oct. 5, 2013 the complete disclosure of which is incorporated herein by reference in its entirety.
The present invention relates to a Halo Tip Spray Head Atomizer Delivery Manifold Device.
Conventional atomizers work by delivering a fine spray. Specialized devices are used for dispensing a plurality of different, i.e., separate, fluid medications or agents as an admixed product. For example, specialized spray heads are used for delivering two biochemically reactive fluids, such as fibrinogen and thrombin to form fibrin in an admixed state, to a biological surface. The biochemically reactive fluids may be delivered topically, in open-type surgeries such as laparotomic procedures, and in minimally invasive surgeries such as laparoscopic procedures.
There exist many techniques for the application of fibrin glues or sealants. In one method, the fibrin sealant components are drawn into a syringe and ejected via an appropriate sized needle. In another method, a double barrel syringe is used. Other conventional techniques include a microdrop delivery system, and a spray application via a multi-channel catheter, which is fixed, to a pressurized air/gas source. These conventional atomizers work by delivering the fibrin glue in a fixed non-adjustable spray pattern.
The Halo Tip Spray Head Atomizer Delivery Manifold Device in accordance with the present invention is especially useful with applications relating to the delivery of such admixtures as fibrin glues. It enables admixtures to be applied statically or through atomization to the specific site in a spray with use of the halo spray tip element or as a static delivery through its dual solution channels and deflectors.
The present invention relates to a halo spray tip atomizer delivery manifold; collectively comprised of a halo spray tip, solution channel insert, and delivery manifold. There exist many techniques for the application of fibrin glues. Application of the fibrin glue can be accomplished in a number of ways. Since fibrin glues exhibit a short set time (time it takes the admixture to harden) once the two biochemically reactive fluid solutions are combine it tends to have the issue of clogging the application device and clogging is always a concern and can be experienced in many of the current application methods. In one method, with admixture with a longer set time and not as prone to clogging the admixture is drawn into a single syringe and ejected via an appropriate sized needle. In another method a double barrel syringe is used and the two solutions are combined in some type of mixing chamber. Other conventional techniques employ a microdrop delivery system, a spray application via a multi-channel catheter which is fixed to a pressurized gas source. Additionally, a number of special applicators are commercially available. Although the example of the use of this invention focuses on fibrin glues it should not be construed as limited to only such application.
In one embodiment, the invention utilizes a halo spray tip atomizer delivery manifold which is connected to an air/gas source through the air channel of the manifold, thus utilizing the atomizer element of the invention. Additionally the air/gas exhaust apertures on the tip and apertures in the solution channel insert may also be varied in size and configuration to affect the particulate size being atomized.
In another embodiment, the invention utilizes a halo spray tip atomizer delivery manifold which is not connected to an air/gas source and not to the air channel of the manifold, thus utilizing only the solution channel insert apertures and solution deflectors on the tip to dispense and combine the two biochemically reactive fluid solutions to create an admixture.
In both afore mentioned, embodiments the fact that the two biochemically reactive fluid solutions are not combined until they are dispensed through the two solution channels and directed by the deflectors to converge into a single stream and finally combined. Depending on the admixture set time the device clogging issue is greatly reduced if not eliminated completely.
The invention may be better understood and appreciated by reference to the detailed description of specific embodiments presented herein in conjunction with the accompanying drawings of which:
A fibrin glue delivery halo tip spray head atomizer delivery manifold device embodying the principles of the invention is provided. The device includes a manifold, a solution channel insert, and a specialized halo spray tip with a radial aperture exhaust configuration, solution stream deflectors, and capable of delivery of an admixture comprised of two biochemically reactive fluid solutions either statically or atomized.

As used in this specification and the appended claims, the term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise.
Unless otherwise noted, technical terms are used according to conventional usage. However, as used herein, the following definitions may be useful in aiding the skilled practitioner in understanding the invention. Such definitions shall be applied, unless a different definition is given in the claims or elsewhere in this specification.
In view of the foregoing disadvantages inherent in conventional fibrin glue application systems, the invention provides a novel system and method for application of fibrin glues. The invention provides a dual function device for use as a non-air/gas assist static delivery device for the dispensing of fibrin glue without atomization as well as the air/gas assist halo spray tip element capable of dispensing the fibrin glue in the form of atomization onto a biological surface.
The full advantage of the combination of the static and halo tip atomization dispensing capabilities in accordance with the invention is realized when optimal spray area and particulate size are achieved through atomization, and additionally when atomization is not require then the static dispensing is utilized. Thus these two capabilities allows for the fibrin glue solution to be applied as effectively as possible while minimizing the device clogging issue communally associated with the application of fibrin glue.
Reference is now made to
The manifold 20 includes a configuration
As shown in
As shown in
In a static method application the two biochemically reactive fluid solutions are introduced into the manifold 20 solution channels 21b.1 and 21c.1 via commonly actuable reservoirs then out though the corresponding solution channels 41a.1, 41a, and 41b.1, 41b in the solution channel insert 40 then through the exhaust aperture 31 in the halo spray tip 30 as individual fluid streams where they come in fluid contact with the concave surfaces of the solution deflectors 31a and 31b of the exhaust aperture 31 in the halo spray tip 30. The solution deflectors 31a and 31b facilitate the joining/directing resulting in convergence of the two solution fluid streams as they exit the exhaust aperture 31 which results in the creation of the admixture.
In a atomization method application as in the use of pressured air/gas the introduction of the two biochemically reactive fluid solutions are as afore described wherein the two solution streams exiting through the exhaust aperture 31 are joined/directed by the deflectors 31a and 31b to converge and create the admixture which is then picked up by the air/gas exhaust which has entered through the isolated unvalved air channel 21a.2 and then through 21a.1 of the manifold 20 the air/gas is then diverter by the air/gas diverter 46 of the solution channel insert 40 and exhausted over surfaces 43a and 43b lastly through the apertures 32a, 32b, 32c, and 32d and in direct contact with the concave inner surfaces 3.2a.1, 32b.1, 32c.1, and 32d.1 of the halo spray tip 30 which results in an atomization of the admixture in a halo effect. The pressure equalizing plenum chambers 50a and 50b created when the solution channel insert 40 and manifold 20 are joined acts to equalize and distribute the air/gas equally through the exhaust apertures 32a, 32b, 32c, and 32d of halo spray tip 30.
