Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
214 words
An anesthetic supply system, safety valve coupler for selectively connecting a conventional anesthetic hose fitting to anesthetic gas delivery means adapted to be connected to a breathing passage of a patient, said valve coupler comprising: anesthetic gas delivery means adapted to be connected to a breathing passage of a patient and having a gas inlet port, an adapter member having a first end including means connected to said gas inlet port of said delivery means and a second end and a fluid passage between said first and second ends; a valve member having a first end with connector means for connecting said valve member to a conventional hose fitting of an anesthetic supply system and a second end with connector means for connecting said valve member to the second end of said adapter member, said valve member including an internal valve means with an acutuator member contacting the second end of said adapter member for opening said valve means on connection of said valve member to the adapter member, and closing said valve means on disconnection of said valve member from the adapter member, said adapter member being proximally located with respect to said delivery means when connected for minimizing gas contamination of the environment when said adapter member and delivery, means are separated.
Claim 2
Dependent Claim
214 words
An anesthetic supply system, safety valve coupler for selectively connecting a conventional anesthetic hose fitting to anesthetic gas delivery means adapted to be connected to a breathing passage of a patient, said valve coupler comprising: anesthetic gas delivery means adapted to be connected to a breathing passage of a patient and having a gas inlet port, an adapter member having a first end including means connected to said gas inlet port of said delivery means and a second end and a fluid passage between said first and second ends; a valve member having a first end with connector means for connecting said valve member to a conventional hose fitting of an anesthetic supply system and a second end with connector means for connecting said valve member to the second end of said adapter member, said valve member including an internal valve means with an acutuator member contacting the second end of said adapter member for opening said valve means on connection of said valve member to the adapter member, and closing said valve means on disconnection of said valve member from the adapter member, said adapter member being proximally located with respect to said delivery means when connected for minimizing gas contamination of the environment when said adapter member and delivery, means are separated.
Claim 3
Dependent Claim
30 words
The valve coupler of claim 1 wherein said valve member and said adapter member are supplied as a replacement kit to substitute for conventional fittings in an anesthetic supply system.
Claim 4
Dependent Claim
33 words
The valve coupler of claim 1 wherein said second end of said adapter member comprises a tapered male connector and said second end of said valve member comprises a complimentary tapered female connector.
Claim 5
Dependent Claim
41 words
The valve coupler of claim 1 wherein said valve means comprises a valve seating structure within said valve member, a poppet constructed to seat on said valve seating structure, and spring means for biasing said poppet against said valve seating structure.
Claim 6
Dependent Claim
50 words
The valve coupler of claim 4 wherein said actuator member comprises a plunger structure connected to said poppet, said plunger structure contacting the second end of said adapter member and displacing said plunger structure and connected poppet on connecting the valve member to the second end of said adapter member.
Claim 7
Dependent Claim
28 words
The valve coupler of claim 5 wherein a tapered connection is utilized for connecting said valve member to the adapter member whereby quick connection and disconnection is provided.
Claim 8
Dependent Claim

The valve coupler of claim 6 wherein said plunger structure comprises a dowel connected to said poppet and a perforated disk connected to said dowel, the second end of said adapter member contacting said disk.
Claim 9
Dependent Claim
192 words
An anesthetic supply system valve coupler for selectively connecting a conventional anesthetic hose fitting to anesthetic gas delivery means adapted to be connected to a breathing passage of a patient, said valve coupler comprising: an anesthetic gas delivery means adapted to be connected to a breathing passage of a patient and having a gas inlet port with connection means having an actuator connector end, a valve member having a first end with connector means for connecting said valve member to a conventional hose fitting of an anesthetic supply system and a second end with connector means connecting said valve member in a sealed connection to said connector means of said delivery means; wherein said valve member includes an internal valve means with an actuator member constructed and positioned to contact the actuating connector end of the delivery means and initiate actuation of the valve means on initial connection of said valve member to the delivery means, prior to a sealed connection being effected, wherein said delivery means has an adequate passage, alternately to atmosphere or to an anesthetic supply in all phases of interconnection of said valve member and the delivery means.
Claim 10
Dependent Claim
192 words
An anesthetic supply system valve coupler for selectively connecting a conventional anesthetic hose fitting to anesthetic gas delivery means adapted to be connected to a breathing passage of a patient, said valve coupler comprising: an anesthetic gas delivery means adapted to be connected to a breathing passage of a patient and having a gas inlet port with connection means having an actuator connector end, a valve member having a first end with connector means for connecting said valve member to a conventional hose fitting of an anesthetic supply system and a second end with connector means connecting said valve member in a sealed connection to said connector means of said delivery means; wherein said valve member includes an internal valve means with an actuator member constructed and positioned to contact the actuating connector end of the delivery means and initiate actuation of the valve means on initial connection of said valve member to the delivery means, prior to a sealed connection being effected, wherein said delivery means has an adequate passage, alternately to atmosphere or to an anesthetic supply in all phases of interconnection of said valve member and the delivery means.
Claim 11
Dependent Claim
101 words
The valve coupler of claim 8 wherein said internal valve means includes a tapered female connection sleeve with an opening, said actuator member being positioned at said opening wherein the actuating connector end of the delivery means is tapered and constructed to insert into said connection sleeve, the connector end contacting and actuating said actuator member on initial insertion into said sleeve and prior to coupled engagement of said connection sleeve and actuating connector end, said actuator member being biased to eject said actuating connector end of said delivery means on inadequate coupling of said valve member and said delivery means.
Claim 12
Dependent Claim
69 words
The valve coupler of claim 9 wherein said valve means includes a displaceable poppet, a poppet seat and a spring biasing said poppet against said poppet seat, wherein said poppet has a stem and a plunger, said plunger being disposed at said opening of said connection sleeve for contact with the tapered connector end of the delivery means an initiating connection of said valve coupler and the delivery means.
