Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
241 words
A coupling device for use with blood sampling apparatus comprising a needle carrier portion, a junction portion, and means for fitting said portions to one another into an operative unit, said needle carrier portion comprising: a. valve means having an axial duct and a vent hole, b. a resilient valve sleeve surrounding said valve means, and including means for sealing said vent hole, said junction portion having an axial bore open at the lower end thereof, and comprising: 1. a junction sleeve disposed in said bore, means for turning the junction sleeve in the bore of the junction portion to a first position, said junction sleeve having an axial duct and a lateral hole, 2. means associated with the needle carrier portion and the junction sleeve for fitting one to another, said last means enabling the turning of the needle carrier portion and the junction sleeve as one unit relative to the junction portion for closing said lateral hole, 3. said junction sleeve having an orifice portion at the upper end of said axial duct, 4. said orifice portion being slightly wider than said valve means, and 5. said junction sleeve being removably coupled to said valve means, whereby in connecting the two portions of the device no air is forced into the first portion by reason of the junction sleeve lifting part of the resilient valve sleeve thereby opening the vent hole to enable escape of air to the atmosphere.
Claim 2
Dependent Claim
241 words
A coupling device for use with blood sampling apparatus comprising a needle carrier portion, a junction portion, and means for fitting said portions to one another into an operative unit, said needle carrier portion comprising: a. valve means having an axial duct and a vent hole, b. a resilient valve sleeve surrounding said valve means, and including means for sealing said vent hole, said junction portion having an axial bore open at the lower end thereof, and comprising: 1. a junction sleeve disposed in said bore, means for turning the junction sleeve in the bore of the junction portion to a first position, said junction sleeve having an axial duct and a lateral hole, 2. means associated with the needle carrier portion and the junction sleeve for fitting one to another, said last means enabling the turning of the needle carrier portion and the junction sleeve as one unit relative to the junction portion for closing said lateral hole, 3. said junction sleeve having an orifice portion at the upper end of said axial duct, 4. said orifice portion being slightly wider than said valve means, and 5. said junction sleeve being removably coupled to said valve means, whereby in connecting the two portions of the device no air is forced into the first portion by reason of the junction sleeve lifting part of the resilient valve sleeve thereby opening the vent hole to enable escape of air to the atmosphere.
Claim 3
Dependent Claim
54 words
The device as set forth in claim 1 in which the junction sleeve comprises a plurality of stops, and the junction portion comprises a plurality of grooves, said stops and grooves constructed to engage one another such as to allow the turning Of the junction sleeve in the junction portion by a predetermined degree.
Claim 4
Dependent Claim
44 words
means associated with the needle carrier portion and the junction sleeve for fitting one to another, said last means enabling the turning of the needle carrier portion and the junction sleeve as one unit relative to the junction portion for closing said lateral hole,
Claim 5
Dependent Claim
44 words
means associated with the needle carrier portion and the junction sleeve for fitting one to another, said last means enabling the turning of the needle carrier portion and the junction sleeve as one unit relative to the junction portion for closing said lateral hole,
Claim 6
Dependent Claim
15 words
said junction sleeve having an orifice portion at the upper end of said axial duct,
Claim 7
Dependent Claim
15 words
said junction sleeve having an orifice portion at the upper end of said axial duct,
Claim 8
Dependent Claim
45 words
The device as set forth in claim 1 in which the means for turning the needle carrier portion and the junction sleeve as one unit includes a plurality of teeth at the needle carrier portion and a plurality of matching teeth at the junction sleeve.
Claim 9
Dependent Claim
54 words
The device as set forth in claim 1 in which the junction portion comprises a second duct open to the open lower end of said bore, and the means for turning the junction sleeve in the bore of the junction portion includes a second position for opening said lateral hole to said second duct.
Claim 10
Dependent Claim
11 words
said orifice portion being slightly wider than said valve means, and
Claim 11
Dependent Claim
11 words
said orifice portion being slightly wider than said valve means, and
Claim 12
Dependent Claim
53 words
said junction sleeve being removably coupled to said valve means, whereby in connecting the two portions of the device no air is forced into the first portion by reason of the junction sleeve lifting part of the resilient valve sleeve thereby opening the vent hole to enable escape of air to the atmosphere.
Claim 13
Dependent Claim
53 words
said junction sleeve being removably coupled to said valve means, whereby in connecting the two portions of the device no air is forced into the first portion by reason of the junction sleeve lifting part of the resilient valve sleeve thereby opening the vent hole to enable escape of air to the atmosphere.
Claim 14
Dependent Claim
46 words
The device as set forth in claim 4 in which the junction portion comprises a third duct and the means for turning the junction sleeve in the bore of the junction portion includes a third position for connecting said lateral hole to the said third duct.
Claim 15
Dependent Claim
44 words
The device as set forth in claim 1 in which the valve means comprises a tapered part at the lower end thereof, and the junction sleeve comprises a tapered part at the upper end thereof, said tapered parts constructed to matingly engage one another.
Claim 16
Dependent Claim
48 words
The device as set forth in claim 6 in which the valve means comprises a fourth duct, said last duct extending in longitudinal direction and structured such as to place the ducts in the valve means in and out of communication with the ducts in the junction sleeve.
