Urine measuring vessel and hose connection
A hose connection for an arrangement for collection of liquid from a patient is disclosed which connection comprises a first tubular member ( 1 ) to be in fluid connection with the patient and having one or more protrusions ( 3 ) arranged on an outer surface, and an outlet ( 2 ), and further comprises a collection bag ( 24 ) having an inlet to be connected to the outlet for collection of liquid coming through the first tubular member. The inlet comprises a second tubular member ( 5 ) being connected to the bag and adapted to receive and surround at least a part of said first tubular member. The second tubular member has one or more receiving means ( 6, 11 ) being engageable with the protrusions for providing a locked, but separable connection between the first and second tubular member.
1. An apparatus for measuring body liquids comprising;
a measuring vessel with a liquid inlet at a top end of the measuring vessel and a liquid outlet at a lower end of the measuring vessel, the measuring vessel comprising a curved inside bottom surface at the lower end provided at each side of a central column,
a measuring scale for reading a volume of urine inside the measuring vessel,
filling elements disposed inside the measuring vessel and above the curved inside bottom surface of the measuring vessel and taking up a predefined volume of the measuring vessel to compensate for the curved bottom surface of the measuring vessel in order to allow for use of a linear measuring scale,
a valve provided with the liquid outlet and a liquid collection bag connected to the liquid outlet and suspended from the measuring vessel, and
a hollow valve body placed in and vertically displaceable with the measuring vessel, the liquid outlet having a shape of a valve seat for the hollow valve body, an interior of the valve body being divided into a reception chamber and an overflow chamber, said reception chamber being connected to the liquid inlet and having at a lower end of the valve body at least one outlet opening which in a closed position of the valve body is closed by the valve seat and which at an upper part of the valve body is connected to the measuring vessel through at least one hole in a chamber wall, the overflow chamber having at a lower end of the overflow chamber a duct which is directly connected to the measuring vessel via a hole in the chamber wall, the holes connecting the reception chamber to the measuring vessel and the measuring vessel to the overflow chamber being placed on a same side of the hollow valve body.
2. An apparatus according to claim 1 , wherein the filling elements comprise projections or recesses provided in and/or on a wall part inside of the measuring vessel.
3. An apparatus according to claim 1 , wherein the filling elements comprise independent fixed or movable elements arranged inside the measuring vessel after manufacture of the measuring vessel.
4. An apparatus according to claim 1 , wherein the inside bottom surface is formed as a circular arc.
5. An apparatus according to claim 1 , wherein the valve body has at an upper end of the valve body a protrusion extending radially from an outside of the valve body which protrusion is placed in a helical groove on an inside of a surrounding part of the measuring vessel so as to cause a vertical displacement of the valve body by rotation of the valve body.
6. An apparatus according to claim 5 , wherein the valve body is provided with a radially extending wing at the upper end of the valve body.
7. An apparatus according to claim 1 , wherein an inside of the measuring vessel comprises one or more protrusions which are in contact with an outside of the valve body and serve as a guide for same.
8. An apparatus according to claim 1 , wherein two annular grooves for O-rings are provided in that zone of the valve body which is in contact with the valve seat when the valve seat is in a closed position.
9. An apparatus according to claim 1 , wherein the valve body is closed at a top by a cover.
10. An apparatus according to claim 9 , wherein the cover comprises a liquid inlet in a form of a tubular member having an inclined end surface covered by a valve flap.
11. An apparatus according to claim 10 , wherein the cover comprises an opening which is covered by an air permeable and liquid tight filter.
12. An apparatus according to claim 1 for measuring and collecting urine.
