Abstract
A device for the controlled supply of a liquid within a medical flow line, includes a retaining body rotatable on an intermediate tubular connector arranged between a tubular inlet connector and a tubular outlet connector of a primary liquid and within which a bottle pierceable and containing a secondary liquid can be fitted. The retaining body includes a hollow piercing spike, rotation blocking means of the retaining body disengageable following insertion of the bottle, axial stop means of the inserted bottle, and progressive opening means of a flow passage from the hollow spike to a flow line of the primary liquid during the rotation of the retaining body with the bottle inserted therein from a first angular position of complete closure to a second angular position of complete opening.

Device for the controlled supply of a medical liquid, including a tubular inlet connector and a tubular outlet connector defining a flow line of a primary fluid and an intermediate tubular transverse connector arranged therebetween for introducing into said flow line a secondary liquid contained within a bottle having a pierceable cap wherein said intermediate connector comprises an annular stationary base on which a hollow retaining body, into which said bottle is to be fitted, is rotatably arranged coaxially with said intermediate connector, said retaining body including:
- a hollow axial spike designed to pierce said pierceable cap when said bottle is fitted into said retaining body, said hollow spike having at least one inner flow passage, rotation blocking means of the retaining body relative to said base in a first angular position, said blocking means being disengageable by said bottle as a result of insertion thereof into said retaining body, stop means for axially retaining said bottle relative to said retaining body, said stop means activated following rotation of said retaining body starting from said first angular position, and progressive opening means of said flow passage of said hollow piercing spike towards said intermediate connector during the rotation of said retaining body from said first angular position, in which communication between said flow passage and said intermediate connector is completely closed, towards a second angular position in which such communication is completely open.
System for the controlled supply of a medical liquid, comprising a bottle containing said liquid and having a pierceable cap, and a device having an inlet and an outlet defining a flow line of a primary fluid for introducing said liquid into said flow line, wherein said device comprises an annular stationary base on which a hollow retaining body, into which said bottle is to be fitted, is rotatably arranged coaxially with said base, said retaining body including:
- a hollow axial spike designed to pierce said pierceable cap when said bottle is fitted into said retaining body, said hollow spike having at least one inner flow passage,
- rotation blocking means of the retaining body relative to said base in a first angular position, said blocking means being disengageabie by said bottle as a result of insertion thereof into said retaining body,
- stop means for axially retaining said bottle relative to said retaining body, said stop means activated following rotation of said retaining body starting from said first angular position, and
- progressive opening means of said flow passage of said hollow piercing spike towards said flow line during the rotation of said retaining body from said first angular position, in which communication between said flow passage and said flow line is completely closed, towards a second angular position in which such communication is completely open.
