PRESSURE REDUCER FOR SUPPLYING DRUGS TO A PATIENT AND CORRESPONDING PRODUCTION METHOD

摘要

The present invention relates to a pressure reducer for delivering drugs to a patient and the corresponding method of manufacture, said pressure reducer for delivering drugs to a patient comprising: a duct (9) with an inlet (11) and an outlet (13), a first body (1) with a first surface (5), and a second body (3) with a second surface (6) directly contacting the first body (1). One of the surfaces (5, 6) has a recess (7) such that a duct (9) is defined between both surfaces. Both bodies are attached to one another by means of a continuous attachment line running on both sides of the duct (9). The method of manufacture comprises a laser welding step in which the first body (1) is welded to the second body (3) by means of a welding seam extending along both sides of the duct.

主权项

1. A pressure reducer for delivering drugs to a patient, suitable for allowing the delivery of a certain fixed nominal flow rate of a drug, the pressure reducer comprising:
a duct with an inlet and an outlet, said duct being suitable for being traversed by said drug; a first body with a first surface; and a second body with a second surface, wherein said first body and said second body define an assembled position in which said first surface is substantially facing said second surface, at least one of said first surface and said second surface having at least one recess such that said duct is formed in said assembled position, said second body directly contacting said first body, such that said duct is defined between said second surface and said first surface, said first body and said second body being attached to one another by means of at least one continuous attachment line extending on both sides of said duct from said inlet to said outlet.
