Abstract
Abstract A valve arrangement for a medical-surgical conduit means including first and second valve members, one of which has a female valve sleeve with ports therein and the other of which has a matingly received male valve sleeve with ports therein. Each of the valve members has mutually opposing faces with mutually engageable locking means on the faces for preventing relative rotation of the members and axial dislodgement thereof. The ports of the male member are arranged so that when the members are locked in and assembled condition the ports are either in communication or out of communication with the female ports depending upon the mode of intended use of the valve arrangement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
244 words
A valve arrangement for use with medical-surgical irrigation apparatus comprising: a first valve member having a body, including a forward wall and a female valve passage opening through the forward wall, said female valve passage having means therein and defining fluid ports; a male valve member having a body including a wall and a male valve element extending from said wall and being of a size and shape to be movably received in said female valve passage, means in said male valve element defining fluid ports therein for alternately establishing communication with said female valve member, said male and female valve members being relatively movable between an open position wherein the female valve port means and the male valve port means are in communication; and a closed position wherein said port means are out of communication with each other; said male and female vaLve members being relatively separable in one of said open and closed positions; and locking means for securing the male and female members together in the other of said open and closed positions against movement from said position and against separation from each other, including recesses in one of the walls of one of the members and projections on the other of the walls of the other of the members, said recesses and projections being oriented relative to said male and female port means to lock the members together when the members are in one of the open and closed positions.
Claim 2
Dependent Claim
244 words
A valve arrangement for use with medical-surgical irrigation apparatus comprising: a first valve member having a body, including a forward wall and a female valve passage opening through the forward wall, said female valve passage having means therein and defining fluid ports; a male valve member having a body including a wall and a male valve element extending from said wall and being of a size and shape to be movably received in said female valve passage, means in said male valve element defining fluid ports therein for alternately establishing communication with said female valve member, said male and female valve members being relatively movable between an open position wherein the female valve port means and the male valve port means are in communication; and a closed position wherein said port means are out of communication with each other; said male and female vaLve members being relatively separable in one of said open and closed positions; and locking means for securing the male and female members together in the other of said open and closed positions against movement from said position and against separation from each other, including recesses in one of the walls of one of the members and projections on the other of the walls of the other of the members, said recesses and projections being oriented relative to said male and female port means to lock the members together when the members are in one of the open and closed positions.
Claim 3
Dependent Claim
96 words
The valve arrangement of claim 1 wherein the female valve passage includes a stop means positioned relative to the forward wall of the valve member for limiting the insertion of the male valve member therein with the male valve member port means being located relative to the male forward wall to be in alignment with said female valve port means when the male and female valve members are assembled together with the male valve member abutting the female valve member stop means and the forward walls of said members are in a face to face abutment.
Claim 4
Dependent Claim
18 words
The valve arrangement of claim 2 wherein the male and female valve members are generally mating hollow sleeves.

Dependent Claim
64 words
The valve arrangement of claim 4 wherein the locking means includes radially outwardly extending ribs on the sleeve of the male valve member spaced forwardly of the forward face thereof and mutually inwardly facing hooklike finger means projecting forwardly from the face of the female valve member being of a size and shape to generally nestably receive the ribs of the male valve member.
Claim 8
Dependent Claim
22 words
The valve arrangement of claim 6 wherein the male valve member sleeve includes a rearward extension for connection to a conduit line.
