Abstract

Flow regulator for the infusion of medicaments, comprising, in succession, a substrate (1), a channel (5), a spacer (3) and a membrane (4), the latter having at least one hole (6) communicating with the channel (5), characterized in that the regulator is produced from at least two separate elements (1-4), the first element comprising the membrane (4) and the second element comprising the spacer (3).

Claims

1. A flow regulator for the infusion of medicaments, comprising in succession a substrate (1), a channel (5), a spacer (3) and a membrane (4), the latter having at least one hole (6) communicating with the channel (5), characterized in that the regulator is produced from at least two separate elements (1-4), the first element comprising the membrane (4) and the second element comprising the spacer (3).

2. The flow regulator as claimed in claim 1, wherein the first element is a sheet.

3. The flow regulator as claimed in claim 1, wherein the second element also comprises the channel (5).

4. The flow regulator as claimed in claim 3, wherein the second element also comprises the substrate (1).

5. The flow regulator as claimed in claim 1, comprising a third element which comprises the substrate (1) and the channel (5).

6. The flow regulator as claimed in claim 1, comprising four elements (1-4), the first (4) comprising the membrane, the second (3) comprising the spacer, the third (2) comprising the channel and the fourth (1) comprising the substrate.

7. The flow regulator as claimed in claim 6, wherein the four elements (1-4) are sheets.

8. The flow regulator as claimed in claim 7, wherein at least one of the sheets (1-4) is obtained by rolling.

9. The flow regulator as claimed in claim 7, wherein at least one of the sheets (1-4) is made of polished silicon.

10. The flow regulator as claimed in claim 9, comprising means for measuring the deflection of the membrane (4).

11. The flow regulator as claimed claim 10, consisting of at least one sheet whose contour is circular.

12. The flow regulator as claimed in claim 11, in which the internal contour of the spacer (3) is circular.

13. The flow regulator as claimed in claim 12, dimensioned so that the fluidic path is obstructed when a threshold pressure of the fluid inside the regulator is reached.

14. A method for manufacturing a flow regulator as claimed in claim 1, comprising the stacking of four sheets (1-4), the first being intended to form the substrate (1), the second a channel (5), the third a spacer (3) and the fourth a membrane (4).

15. The method as claimed in claim 14 comprising a step of aligning the sheets (1-4).

16. The manufacturing method as claimed in claim 1, characterized in that the spacer (3) and/or the channel (5) are created by electroplating or any other deposition method.
