Abstract
A connecting piece for a tubing including a first unit and a second unit is provided. The first unit includes a first connecting element for a tubing element and a second connecting part for the second unit. The second connecting element includes a tubular female part for engagement with the second unit and first sealing elements, and the second unit includes a tubular male part with a collar and second sealing elements for cooperating with the first sealing elements. The first and second units further include separator elements. The first sealing elements and the second sealing elements are configured for mutual locking engagement by moving a male part and a female part axially towards each other.
Claims21
A connecting piece for a medical tubing, said connecting piece comprising a first unit and a second unit,
- said first unit comprising a first connecting element for a tubing element and a second connecting element for the second unit, said second connecting element comprising a tubular female part for engagement with the second unit and first sealing elements,
- said second unit comprising a tubular male part having a tubular portion fitting inside and surrounded by a portion of said tubular female part, and having a collar including a continuously extending delimiting edge defining a face on said male part, a connecting line between any two points along said delimiting edge in a peripheral direction of the male part being less than 90° in relation to an axial extension of said male part and said female part, said tubular portion of said male part having second sealing elements for cooperating with the first sealing elements,
- said first unit and second unit comprising respective separator elements, the first sealing elements and the second sealing elements configured for being mutually lockingly engageable by moving the male part and the female part axially towards each other, said mutual locking engagement establishing a lock, by which the first unit and the second unit are kept together with said tubular portion of said male part extending inside said female part;
- the separator elements comprising a face arranged on the female part and a face arranged on the male part, said faces being in abutment against each other when the first unit and the second unit are kept together by said lock, said faces being such that by a turning of the first unit in relation to the second unit an axially extending positive force component is provided for by said face on said male part riding on said face on said female part, said positive force component forcing the first and second units to disengage and to leave their mutual engagement by axial displacement;
- and
- the separator elements being arranged in relation to said sealing elements such that said separator elements are at an axial distance from said lock when the first unit and the second unit are kept together by said lock.

A device for leak-proof connection of medical tubing, said device comprising a first unit and a second unit;
- said first unit comprising:
- a connecting portion that is connectable to a first medical tube,
- a tubular female portion defining an axial direction of said device and having a through-going passage, said tubular female portion comprising first sealing elements arranged within said through-going passage, and
- at least one first face disposed along a periphery of said first unit, said second unit comprising:
- a connecting portion that is connectable to a second medical tube,
- a tubular male portion comprising second sealing elements, said tubular male portion being receivable inside said through-going passage of said tubular female portion, and
- at least one second face disposed along a periphery of said second unit,
- said first and second sealing elements are lockable together to form a leak-proof engagement when said tubular male portion is received inside said through-going passage of said tubular female portion, said first and second sealing element engagement locking said tubular male portion against withdrawal from said tubular female portion,
- said at least one first face is movable along said at least one second face from said engagement and said tubular male portion being twistable relative to said tubular female portion to provide a force in said axial direction for driving said first unit away from said second unit to disengage said first unit from said second unit,
- said at least one first face is axially spaced apart from said first sealing elements and said at least one second face is axially spaced apart from said second sealing elements.

A device for leak-proof connection of medical tubing, said device comprising a first unit releasably connected to a second unit;
- said first unit comprising:
- a connecting portion that is connectable to a first medical tube,
- a tubular female portion defining an axial direction of said device and having a through-going passage, and
- at least one first face disposed along a periphery of said first unit, said second unit comprising:
- a connecting portion that is connectable to a second medical tube,
- a tubular male portion, and
- at least one second face disposed along a periphery of said second unit,
- said tubular male portion being received inside said through-going passage of said tubular female portion,
- said tubular female portion comprising first sealing elements arranged within said through-going passage, and
- said tubular male portion comprising second sealing elements,
- said first and second sealing elements being in leak-proof engagement with each other and releasably locking said tubular male portion against withdrawal from said tubular female portion,
- said at least one first face is movable along said at least one second face when said tubular female portion is twisted relative to said tubular male portion, to provide a force in said axial direction for driving said second unit away from said first unit to disengage said second unit from said first unit,
- said at least one first face is axially spaced apart from said first sealing elements and said at least one second face is axially spaced apart from said second sealing elements.
