Disposable valve unit for regulating a flow of urine
View Patent ↗A valve unit for regulating a flow and a disposable urine bag are provided. The valve unit includes an inlet portion and an outlet portion separated from each other by a slide valve. The slide valve includes a female part in direct communication with the inlet portion and the outlet portion and a male part axially displaceable in liquid-proof contact with the female part. The male part includes a closing position wherein a portion of the male part is outside the female part and an open position wherein the male part allows liquid passage between the inlet portion and the outlet portion by means of a communication part. The female part includes a tubular member open at both ends and having a tubular wall extending along the entire length of the male part in the open position for deterring displacement of the male part to the closed position.
1. A valve unit for regulating a flow of urine, said valve unit comprising an inlet portion and an outlet portion separated from each other by a slide valve, said slide valve comprising a valve housing formed as a female part in direct communication with the inlet portion and the outlet portion, and a valve body formed as a male part being axially displaceable in parallel and in liquid-proof contact with the female part, said male part being configured for assuming two positions, a closing position and an open position, in which closing position a portion of the male part is outside the female part; that, in the closing position and in the area where the inlet portion and the outlet portion connect to the female part, outer faces of the male part provide a liquid-proof blocking between the inlet portion and the outlet portion; that, in the open position, the male part allows liquid passage between said inlet portion and said outlet portion by means of a communication part; wherein said female part comprises a tubular member open at both ends and having a tubular wall extending along the entire length of said male part in said open position to completely enclose said valve body in said open position with no portion of said valve body projecting from said valve housing, for deterring displacement of said valve body to said closed position.
2. A valve unit according to claim 1 , said closing position and open position being two extreme positions of said male part.
3. A valve unit according to claim 1 , wherein the communication part is provided by an opening transversally through the male part and perpendicular to its longitudinal axis.
4. A valve unit according to claim 1 , wherein the communication part comprises at least one rib that connects a first part and a second part of the male part.
5. A valve unit according to claim 1 , wherein both the inlet portion and the outlet portion comprise a tubular member.
6. A disposable urine bag for collecting urine, said bag comprising an upper delimiting edge, a lower delimiting edge, and side-delimiting edges, said edges defining a cavity in the bag, said upper delimiting area situated at the upper delimiting edge being in communication with means outside the bag, and said lower delimiting edge comprising a valve unit comprising an inlet portion and an outlet portion separated from each other by a slide valve, said slide valve comprising a valve housing formed as a female part in direct communication with the inlet portion and the outlet portion, and a valve body formed as a male part being axially displaceable in parallel and in liquid-proof contact with the female part, said male part configurable into a closing position wherein a portion of the male part is outside the female part; so that outer faces of the male part provide a liquid-proof blocking between the inlet portion and the outlet portion; and an open position, wherein the male part allows liquid passage between inlet portion and outlet portion by means of a communication part; that the inlet portion communicates with the cavity of the bag; and the outlet portion is situated outside the delimiting edges of the bag, wherein said female part comprises a tubular member open at both ends and having a tubular wall extending along the entire length of said male part in said open position to completely enclose said valve body in said open position with no portion of said valve body projecting from said valve housing, for deterring displacement of said valve body to said closed position.
7. The disposable urine bag of claim 6 , wherein the closing position and the open position comprise two extreme positions of the male part.
8. A valve unit for regulating a flow of urine, said valve unit comprising:
an inlet portion and an outlet portion separated from each other by a slide valve, said slide valve comprising:
a valve housing formed as a female part in direct communication with the inlet portion and the outlet portion, and
a valve body formed as a male part being axially displaceable in parallel and in liquid-proof contact with the female part, said male part configurable into a closing position wherein a portion of the male part is outside the female part at a first end of said female part so that outer faces of the male part provide a liquid-proof blocking between the inlet portion and the outlet portion; and an open position wherein the male part allows liquid passage between the inlet portion and the outlet portion by means of a communication part;
wherein said female part comprises a tubular member closed by a rigid closure plate at a second end opposite said first end and having a tubular wall extending along the entire length of said male part in said open position to completely enclose said valve body in said open position with no portion of said valve body projecting from said valve housing, for deterring displacement of said valve body to said closed position.
