First Claim
1. A modular system (10) including at least first (20) and second (30) units having respective housings, wherein the housing of said first unit (20) carries at least a first connection part (23 resp. 24) for mechanical and electrical connection with a second, complementary connection part (24 resp. 23) carried by the housing of said second unit (30), said first and second parts (23, 24) being arranged in the respective housings in a mutual facing relationship enabling connection of said two connection parts (23, 24) as said first (20) and second (30) units are arranged one against the other, wherein the system includes a plurality of said second units (3), at least one of said second units (30) of said plurality of said second units being, provided with both said first and said second connection parts (23,24) on opposite sides thereof, whereby said units of said plurality of said second units can be arranged in a stack and wherein:
- said first connection part (23) includes;
a first plug (33);
a rotary member (32) mounted in proximity of said first plug (3,3) and adapted for rotation from a first angular position towards a second angular position and further on towards a third angular position;
said rotary member (32) carrying a respective lock member (42) assuming respective first and second positions as said rotary member (32) reaches said second and third angular positions, respectively; and
said second connection part (24) includes;
a second lug (44) adapted for connection with said first plug (33) in said first connection part (23), anda protruding member (43) adapted to cooperate with said lock member (42) in said first connection part (23) whereby, as said first (20) and second (30) units are arranged one against the other with said rotary member (32), in said first connection part (23) in said second angular position, said protruding member (43) in said second connection part (24) engages said lock member (42) in said first connection part (23) and as said rotary member (32) in said first connection part (23) is moved to said third angular position, the respective lock member (43) reaches said respective second position thereby locking said protruding member (43) of said second connection part (24) to said first connection part (23).

Abstract
A modular system (10) is disclosed for use, e.g. in infusion systems. The system includes a base unit (20) and one or more modules (30). A mechanical/electrical connecting system (21 to 24) is disclosed enabling safe connection of the various units in the system while enabling easy disconnection of any of the modules (30). A signal processing arrangement is also disclosed enabling the number of modules (30) in the system to be sensed by the base unit (20).

1. A modular system (10) including at least first (20) and second (30) units having respective housings, wherein the housing of said first unit (20) carries at least a first connection part (23 resp. 24) for mechanical and electrical connection with a second, complementary connection part (24 resp. 23) carried by the housing of said second unit (30), said first and second parts (23, 24) being arranged in the respective housings in a mutual facing relationship enabling connection of said two connection parts (23, 24) as said first (20) and second (30) units are arranged one against the other, wherein the system includes a plurality of said second units (3), at least one of said second units (30) of said plurality of said second units being, provided with both said first and said second connection parts (23,24) on opposite sides thereof, whereby said units of said plurality of said second units can be arranged in a stack and wherein:
-
said first connection part (23) includes; a first plug (33); a rotary member (32) mounted in proximity of said first plug (3,3) and adapted for rotation from a first angular position towards a second angular position and further on towards a third angular position;
said rotary member (32) carrying a respective lock member (42) assuming respective first and second positions as said rotary member (32) reaches said second and third angular positions, respectively; andsaid second connection part (24) includes; a second lug (44) adapted for connection with said first plug (33) in said first connection part (23), and a protruding member (43) adapted to cooperate with said lock member (42) in said first connection part (23) whereby, as said first (20) and second (30) units are arranged one against the other with said rotary member (32), in said first connection part (23) in said second angular position, said protruding member (43) in said second connection part (24) engages said lock member (42) in said first connection part (23) and as said rotary member (32) in said first connection part (23) is moved to said third angular position, the respective lock member (43) reaches said respective second position thereby locking said protruding member (43) of said second connection part (24) to said first connection part (23). - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. A unit (20, 30) for use in a modular system, said unit having a respective housing, wherein said housing carries at least one of a first (23 resp. 24) and a second (24 resp. 23) connection part each for mechanical and electrical connection with a complementary connection part carried by the housing of at least one further unit in the system, said at least one of a first and a second connection parts (23, 24) being arranged in said housings in a facing relationship enabling connection with said complementary connection part (23, 24) as said unit and said further unit are arranged one against the other, wherein:
-
said first connection part (23) includes; a first plug (33); a rotary member (32) mounted in proximity of said first plug (33) and adapted for rotation from a first angular position towards a second angular position and further on towards a third angular position;
said rotary member (32) carrying a respective lock member (42) assuming respective first and second positions as said rotary member (32) reaches said second and third angular positions, respectively; andsaid second connection part (23) includes; a second plug (44) adapted for connection with said first plug (33) and a protruding member (43) adapted to cooperate with said lock member (42) in said first connection part (23) whereby, as said unit and said further unit are arranged one against the other with said rotary member (32) in said first connection part (23) in said second angular position, said protruding member (43) in said second connection part (24) engages said lock member (42) in said first connection part (23) and as said rotary member (32) in said first connection part (23) is moved to said third angular position, the respective lock member (43) reaches said respective second position thereby locking said protruding member (43) of said second connection part (24) to said first connection part (23). - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
