Abstract

Abstract A semi-rigid tubular member for insertion into the uterine canal and preferably into the uterine cavity through which fluid may be injected, sealing structure communicating with the tubular member for sealing the external orifice of the cervical canal, and a syringe communicating with said tubular member for holding material to be injected. The device is particularly useful for effectively injecting a small volume of concentrated spermatozoa directly into the uterine cavity without irritation.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 170 words
A device for injecting material directly into the uterine cavity of the non-pregnant uterus which comprises: a semi-rigid tubular member for insertion into the uterine canal through which fluid may be injected; sealing means communicating with said tubular member for sealing the external orifice of the cervical canal including an enlarged base portion of said tubular member which sealingly fits into the external orifice and tightly seals said external orifice, said sealing means and tubular member permitting free circulation of said fluid in the uterine cavity and uterine canal; a syringe communicating with said tubular member for holding the fluid to be injected; a speculum for insertion into the vagina in cooperation with said syringe; and a resilient means engaged with said speculum for retaining said sealing means in sealing engagement with the external orifice of the cervical canal by urging said resilient means into sealing engagement with the external orifice of the cervical canal, wherein said device has a minimum amount of dead space less than about 0.1 cc.
Claim 2
Independent Claim 170 words
A device for injecting material directly into the uterine cavity of the non-pregnant uterus which comprises: a semi-rigid tubular member for insertion into the uterine canal through which fluid may be injected; sealing means communicating with said tubular member for sealing the external orifice of the cervical canal including an enlarged base portion of said tubular member which sealingly fits into the external orifice and tightly seals said external orifice, said sealing means and tubular member permitting free circulation of said fluid in the uterine cavity and uterine canal; a syringe communicating with said tubular member for holding the fluid to be injected; a speculum for insertion into the vagina in cooperation with said syringe; and a resilient means engaged with said speculum for retaining said sealing means in sealing engagement with the external orifice of the cervical canal by urging said resilient means into sealing engagement with the external orifice of the cervical canal, wherein said device has a minimum amount of dead space less than about 0.1 cc.
Claim 3
Dependent Claim 13 words
A device according to claim 1 wherein said resilient means is a spring.
Claim 4
Dependent Claim 30 words
A device according to claim 1 including a holder for holding said syringe, wherein said sealing means is supported by said holder and wherein said resilient means engages said holder.
Claim 5
Dependent Claim 48 words
A device according to claim 3 including a speculum for insertion into the vagina with the holder inserted into the speculum, wherein said resilient means is engaged between said holder and speculum and urges said sealing means into sealing engagement with the external orifice of the cervical canal.
Claim 6
Dependent Claim 16 words
A device according to claim 1 wherein said sealing means is integral with said tubular member.
Claim 7
Dependent Claim 25 words
A device according to claim 5 wherein said sealing means is adjacent said syringe to enable fluid to be injected directly into said tubular member.
Claim 8
Dependent Claim 41 words
A device according to claim 1 wherein said tubular member has a tapered, curved anterior end and an enlarged posterior end, with a central passageway having an inlet orifice at the posterior end and an exit orifice behind the anterior end.
Claim 9
Dependent Claim 17 words
A device according to claim 1 wherein said sealing means is fixedly secured to said tubular member.
Claim 10
Dependent Claim 26 words
A device according to claim 1 including means associated with said tubular member to permit circulation of said fluid between said uterine cavity and uterine canal.
Claim 11
Independent Claim 131 words
A device for injecting material directly into the uterine cavity of the non-pregnant uterus which comprises: a semi-rigid tubular member suitable for insertion into both the uterine canal and uterine cavity through which fluid may be injected including at least one longitudinal groove terminating before the end thereof to permit access from the uterine cavity to the uterine canal; sealing means communicating with said tubular member for sealing the external orifice of the cervical canal including an enlarged base portion of said tubular member which sealingly fits into the external orifice and tightly seals said external orifice, said sealing means and tubular member permitting free circulation of said fluid in the uterine cavity and uterine canal; and a syringe communicating with said tubular member for holding the fluid to be injected.
Claim 12
Independent Claim 131 words
A device for injecting material directly into the uterine cavity of the non-pregnant uterus which comprises: a semi-rigid tubular member suitable for insertion into both the uterine canal and uterine cavity through which fluid may be injected including at least one longitudinal groove terminating before the end thereof to permit access from the uterine cavity to the uterine canal; sealing means communicating with said tubular member for sealing the external orifice of the cervical canal including an enlarged base portion of said tubular member which sealingly fits into the external orifice and tightly seals said external orifice, said sealing means and tubular member permitting free circulation of said fluid in the uterine cavity and uterine canal; and a syringe communicating with said tubular member for holding the fluid to be injected.
