Applicator for applying a biocompatible adhesive
First Claim
1. An applicator useful for applying a biocompatible adhesive containing human or animal protein to a surgical site of a living body, comprisinga spray head,a pair of syringes each including a barrel and a nozzle at one end of the barrel, the syringes adapted to feed a protein solution and a coagulation solution, wherein the nozzles are fitted into the spray head, wherein the spray head is adapted to spray the protein and coagulation solutions fed from the syringes by ejection of a sterile gas, wherein the spray head comprisesa housing including a pair of adapters for receiving the nozzles of the syringes,a pair of adjacent sterile-gas ejecting nozzles in the housing, each having a longitudinal axes, wherein the longitudinal axis thereof are arranged for guiding and ejecting the sterile gas, anda pair of solution tubes, one arranged and associated within each sterile-gas ejecting nozzle, each having a longitudinal axes parallel to the longitudinal axes of the gas ejecting nozzles, wherein one end of each of the solution tubes is connected to one of the adapters, and the other end of each solution tube protrudes from the end of the associated sterile-gas ejecting nozzle, wherein the solution tubes are arranged such that when the solutions are fed from the syringes, they are conveyed through the solution tubes and ejected therefrom, anda sterile-gas supply tube connected to the interior of the housing adapted to supply the sterile gas.

Abstract
An applicator for applying a biocompatible adhesive containing human or aal protein as a principal ingredient to a surgical site of living body includes a housing to which a sterile gas is supplied, a sterile-gas supply tube connected to the housing, two adjacent sterile-gas ejecting nozzles for ejecting the sterile gas in the same direction, two adapters to which respective nozzles of syringe barrels are connected, and a pair of solution tubes, each having one end connected to the adapter and the other end protruded outwardly from the sterile gas ejection nozzle through an interior of the housing. Respective solutions supplied from the syringes via the pair of barrel adapters are ejected from the outlets of the solution tubes. The sterile gas is ejected from two sterile-gas ejection nozzles in the same direction. Consequently, the solutions are sprayed and mixed by the sterile gas, and then applied to the surgical site.
