Urinary drainage devices

Claim 2

A collection bag means for urine, comprising a bag means defined by four side means, inlet tube means and outlet tube means, said outlet tube means having a wide bore, said inlet tube means and said outlet tube means being connected with two opposite side means of said four side means defining said bag means, and tap means comprising a main hollow tube inserted in said outlet tube means and forming a bore at least as wide as the bore of said outlet tube means, and two coaxial hollow members extending transversely from opposite sides of said main hollow tube to avoid constriction of the bore of said main hollow tube, one of said members having greater length than the other of said members, and valve member means, said valve member means having a close sliding fit in said two hollow members, wherein said valve member means has two portions of unequal length but of the same diameter and a connector portion, said connector portion connecting said two portions of unequal length whereby a space is defined between said two portions, said longer of said two portions being mounted in said shorter of said two coaxial hollow members of said tap means whereby said tap means can be actuated single-handedly between open and closed positions by an operator.

Claim 3

A collection bag means as defined in claim 1, wherein said inlet tube means has at an end remote from said bag means connector cap means, there being intermediate said bag means and said connector cap means a length of said outlet tube means comprised of a material which is self-sealing once it has been punctured by a sharp instrument and said sharp instrument has been withdrawn.

Claim 4

A collection bag means for urine, comprising a bag means defined by four side means, inlet tube means and outlet tube means, said outlet tube means having a wide bore, said inlet tube means and said outlet tube means being connected with two opposite side means of said four side means defining said bag means, and tap means comprising a main hollow tube inserted in said outlet tube means and forming a bore at least as wide as the bore of said outlet tube means, and two coaxial hollow members extending transversely from opposite sides of said main hollow tube to avoid constriction of the bore of said main hollow tube, and sliding valve member means mounted in said transverse hollow members with a close sliding fit, said sliding valve member means having first portion means and second portion means being spaced apart and coaxial, and a connector piece means of less cross-sectional area than said first and second portion means being connected by said connector piece means, said first and second portion means being of unequal length, whereby when said tap means is open, said connector piece means extends across said major axis of said main hollow tube and said first portion means of said valve member means extends beyond a lateral extremity of the shorter one of said transverse hollow members.

Claim 5

A collection bag means for urine, comprising a bag means defined by four side means, inlet tube means and outlet tube means, said outlet tube means having a wide bore, said inlet tube means and said outlet tube means being connected with two opposite side means of said four side means defining said bag means, and tap means comprising a main hollow tube inserted in said outlet tube means and forming a bore at least as wide as the bore of said outlet tube means, and two coaxial hollow members extending transversely from opposite sides of said main hollow tube to avoid constriction of the bore of said main hollow tube, and sliding valve member means mounted in said transverse hollow members with a close sliding fit, said sliding valve member means having first portion means and second portion means being spaced apart and coaxial, and a connector piece means of less cross-sectional area than said first and second portion means being connected by said connector piece means, said first and second portion means being of unequal length, whereby when said tap means is open, said connector piece means extends across said major axis of said main hollow tube and said first portion means of said valve member means extends beyond a lateral extremity of the shorter one of said transverse hollow members.

Claim 6

A collection bag means as defined in claim 3, wherein said inlet tube means has at an end remote from said bag means connector cap means, there being intermediate said bag means and said connector cap means a length of said outlet tube means comprised of a material which is self-sealing once it has been punctured by a sharp instrument and said sharp instrument has been withdrawn.

Claim 7

A collection bag as defined in claim 3, wherein, outlet tube means terminates in an outlet downstream of said tap means which is short relative to the length of said tube means upstream of said tap means, said outlet terminating obliquely at a cut-away portion at an acute angle relative to the said major axis of said outlet tube means.

Claim 8

A collection bag means for urine, comprising a bag means defined by four side means, inlet tube means and outlet tube means, said outlet tube means having a wide bore, said inlet tube means and said outlet tube means being connected with two opposite side means of said four side means defining said bag means, and tap means comprising a main hollow tube inserted in said outlet tube means and forming a bore at least as wide as the bore of said outlet tube means, and two coaxial hollow members extending transversely from opposite sides of said main hollow tube to avoid constriction of the bore of said main hollow tube, one of said members having a greater length than the other of said members, and valve member means, said valve member means having a close sliding fit in said two hollow members, wherein said valve member means has two portions of unequal length but of the same diameter and a connector portion, said connector portion connecting said two portions of unequal length whereby a space is defined between said two portions, said longer of said two portions being mounted in said shorter of said two coaxial hollow members of said tap means, wherein said inlet tube means has at an end remote from said bag means connector cap means, there being intermediate said bag means and said connector cap means a length of said outlet tube means comprised of a material which is self-sealing once it has been punctured by a sharp instrument and said sharp instrument has been withdrawn.

Claim 9

A collection bag means for urine, comprising a bag means defined by four side means, inlet tube means and outlet tube means, said outlet tube means having a wide bore, said inlet tube means and said outlet tube means being connected with two opposite side means of said four side means defining said bag means, and tap means comprising a main hollow tube inserted in said outlet tube means and forming a bore at least as wide as the bore of said outlet tube means, and two coaxial hollow members extending transversely from opposite sides of said main hollow tube to avoid constriction of the bore of said main hollow tube, one of said members having a greater length than the other of said members, and valve member means, said valve member means having a close sliding fit in said two hollow members, wherein said valve member means has two portions of unequal length but of the same diameter and a connector portion, said connector portion connecting said two portions of unequal length whereby a space is defined between said two portions, said longer of said two portions being mounted in said shorter of said two coaxial hollow members of said tap means, wherein said inlet tube means has at an end remote from said bag means connector cap means, there being intermediate said bag means and said connector cap means a length of said outlet tube means comprised of a material which is self-sealing once it has been punctured by a sharp instrument and said sharp instrument has been withdrawn.
