Claims (20)

1. 1. A connecting system including:
2. an interface comprising a housing and a sensor located in the housing, wherein the sensor is configured to be displaceable between a first position, a second position and a third position;
3. a reusable fitting comprising at least one interaction surface and a slot-like space, wherein the reusable fitting is configured to be at least partially fixed in the housing so that said at least one interaction surface is configured to shift the sensor between a first position and a second position;
4. a disposable fitting comprising a radial projection, wherein the disposable fitting is configured to be at least partially fixed in a reusable fitting with the radial projection positioned in the slotted space and passing through it, shifting the sensor between a second position and a third position,
5. wherein the sensor is configured to detect a displacement between the first position and the second position, thereby detecting partial engagement between the reusable fitting and the interface, and
6. wherein the sensor is configured to detect a displacement between the second position and the third position, thereby detecting partial contact between the disposable fitting and the reusable fitting.
7. 2. The connecting system according to claim 1, in which the sensor, when shifted to the second position, detects complete engagement between the reusable fitting and the interface, and when shifted to the third position, detects complete engagement between the disposable fitting and the reusable fitting.
8. 3. The connecting system according to claim 2, in which the sensor, displaced into the gap between the first position and the second position, detects partial contact between the reusable fitting and the interface, and displaced into the gap between the second position and the third position, detects partial contact between the disposable fitting and the reusable fitting.
9. 4. The connecting system according to paragraphs 1-3, in which the sensor comprises a lever, a leg and a spring passing around the leg, in which the lever is configured to rotate around the leg as a result of coming into contact with at least one interaction surface and a protrusion, and in which the spring is configured to bias the lever in the direction of the first position.
10. 5. The connecting system of claim 4, wherein the sensor further comprises a magnet located inside the leg and a printed circuit board located at a distance from the magnet, wherein the printed circuit board is configured to detect rotation of the magnet when the lever rotates around the leg.
11. 6. The connecting system according to paragraphs 1-5, in which the reusable fitting comprises a body that forms a channel and at least a first part of a slotted space, wherein the channel at least partially forms a first fluid-conducting path, and wherein at least one interaction surface protrudes from the body.
12. 7. The connecting system according to claim 6, wherein at least one interaction surface comprises a flat part protruding from the body and a curved part protruding from the flat part.
13. 8. The connecting system according to claim 7, wherein at least one interaction surface comprises a first interaction surface and a second interaction surface, wherein the first and second interaction surfaces form between themselves at least a second part of a slot space.
14. 9. The connecting system of paragraphs 6-8, in which the reusable fitting further comprises at least one wing protruding from the body, and in which said at least one wing is configured to engage with the body to secure the reusable fitting at the interface.
15. 10. The connecting system of claim 9, wherein at least one wing comprises a wedge-shaped leading edge and a retaining rib, wherein the wedge-shaped leading edge is configured to deform upon connection and disconnection from the body, and wherein a thrust projection is formed in the body, wherein the thrust projection is configured to engage with the retaining rib and thereby secure the reusable fitting in the body.
16. 11. The connecting system of paragraphs. 6-10, in which the disposable fitting comprises a body and a connector protruding from the body, wherein the connector is configured to mate with the channel, and wherein the body of the disposable fitting and the connector at least partially form a second fluid path configured to be brought into alignment with the first fluid path when the connector is mated with the channel, and wherein the radial projection extends from the connector.
17. 12. The connecting system of claim 11, wherein the disposable fitting comprises a locking lever extending from the body of the disposable fitting, and a socket is formed in the body of the reusable fitting, and wherein the locking lever is configured to engage with the socket, thereby at least partially locking the disposable fitting within the reusable fitting.
18. 13. The connecting system according to paragraphs 1-12, in which the disposable fitting is fixed inside the reusable fitting, and the reusable fitting is fixed inside the housing, and the disposable fitting and the reusable fitting are designed with the possibility of maintaining the fixation of the disposable fitting inside the reusable fitting when the reusable fitting is removed from the housing.
19. 14. A connecting system comprising:
20. interface including:
