Definitions
- the invention relates to a pressure reducer for the supply of medicaments to a patient, capable of allowing the delivery of a certain fixed nominal flow of medication, comprising: [a] a conduit with an inlet and an outlet, where the conduit it is apt to be traversed by the medicament, [b] a first body with a first surface, and [c] a second body with a second surface, where the first body and the second body define a mounted position in which the first surface it is substantially facing the second surface, and where at least one of the surfaces has at least one recess in such a way that, in the assembled position, the conduit is formed.
- the invention also relates to a process for manufacturing a pressure reducer of the type indicated.
- Pressure reducers of the type indicated above are known.
- devices that provide a supply for a period of time more or less long, such as the "drop-deplete" by gravity, the elastomeric pumps, mechanical pumps, etc.
- These devices usually create an overpressure in the medicine at the entrance of the blood vessel, for example by the elastic force of the elastomeric pump balloon, by the mechanical force of the mechanical pump, by the difference in heights between the bag containing the medicine. and the point of entry into the blood vessel, etc.
- these devices usually include a pressure reducer, positioned at any intermediate point between the pressure generating device and the entry into the blood vessel. In general, these devices should provide medication flows as uniform as possible, and as close as possible to a certain nominal value.
- the basic function of the pressure reducer is precisely to reduce the pressure. They usually comprise a conduit that, when traversed by the medicine, experiences a loss of pressure, said pressure loss being basically a function of two parameters: the length and the cross section of the conduit.
- Pressure reducers are designed specifically for each type of specific application, that is, they are designed taking into account what type of device they will be connected to, and what flow rate you want to deliver to the patient. Thus, for example, if it is desired to design a pressure reducer that, connected to an elastomeric pump, allows the delivery of a given flow of medication, the pressure supplied by the elastomeric pump balloon and the losses of pressure must be taken into account.
- Various types of pressure reducers are known, such as those formed by a glass tube with a very small internal diameter, those with a long length capillary tube, etc.
- WO 02/41938 which describes pressure reducers of the type indicated at the beginning.
- a gasket of elastomeric material is inserted between the first body and the second body. This seal is the one that makes the seal and, in part, deforms by partially entering the conduit, as described in the aforementioned document WO 02/41938 (for example on page 3 line 27 to page 6 line 2 , page 7 line 26 to 34, page 1 1 line 26 to page 13 line 8, Figs. 1 to 7).
- the object of the invention is to overcome these drawbacks.
- This purpose is achieved by means of a pressure reducer of the type indicated at the beginning characterized in that the second body is directly in contact with the first body, such that between the second surface and the first surface the duct is defined and because the first body and the second body are united each other by at least one continuous connecting line that runs both sides of the conduit from the entrance to the exit. Indeed, in this way it is achieved that the second body, which is a rigid piece, closes the duct in a tightly sealed way directly.
- this continuous joining line is a weld that, advantageously, is made by laser.
- the laser makes it easy to make weld seams of great length and complex geometries, which allows to make the required continuous bonding line.
- Pressure reducers of the type indicated at the beginning may have various shapes, although preferably they are substantially flattened.
- the duct is usually a race arranged on the first surface of the first body (although it can also be partially complemented by a race arranged on the second surface of the second body).
- the pressure reducer according to the invention has two continuous connecting lines, one on each side of the duct and extending from the inlet to the outlet.
- the second body is made of a transparent material at a preset wavelength, and advantageously the first body is absorbent of this preset wavelength.
- the first body is absorbent of this preset wavelength.
- any laser having the appropriate power and precision can be used, but it is particularly advantageous to use a laser with ytterbium crystal (Yb).
- the preset wavelength is preferably 1070 nm (nanometers) or 1064 nm.
- the second body is made of polymethylmethacrylate (PMMA). This material is transparent to the preferred wavelengths indicated above.
- the first body is methyl methacrylate acrylonitrile butadiene styrene (MABS).
- MABS methyl methacrylate acrylonitrile butadiene styrene
- the first body is absorbed of a predetermined wavelength, in order to be able to do the laser welding.
- the first body can be made from a material that is absorbent of said wavelength or can be of any other material (transparent to said wavelength) and include an additive that is absorbent of wavelength in question.
- the second body is a sheet with a second smooth surface, and advantageously has a thickness between 20 microns and 500 microns. It is particularly advantageous to have a thickness between 40 microns and 200 microns. Indeed, the second body can thus be obtained by punching a prefabricated sheet, which facilitates and makes it cheaper to obtain. With these thicknesses the second body is already rigid enough to fulfill its function and allows an adequate laser welding. In the case that the second body is a sheet as indicated, it is advantageous to subsequently mount, on the already welded sheet, a cover whose function is to protect the sheet. Another alternative could be to directly mount a second body that has a high thickness, preferably between 0.5 mm and 2 mm, in which case the addition of a cover is no longer recommended.
- a subject of the invention is also a method of manufacturing a pressure reducer according to the invention, characterized in that it comprises a laser welding stage in which the first body is welded to the second body by at least one welding bead that is extends along both sides of the duct from the entrance to the exit.
- the welding stage is made with an iterbium laser, preferably a continuous wave fiber laser.
- the laser can be for example the fiber laser model IPG YLM-20-SC®, continuous wave and 20 W of power maximum, with a TWIST® head developed by ILT Fraunhofer.
- This laser has a focal length of 100 mm to 254 mm and a focus diameter of between 40 microns and 75 microns.
- the method comprises a stage in which a cover is fixed that covers, at least partially, the second body. Alternatively, as already mentioned above, a second body of a greater thickness can be used so that the addition of a lid is no longer advisable.
- FIGs. 1 to 3 plan views, partially sectioned elevation and perspective of a first body of a pressure reducer according to the state of the art.
- FIGs. 4 and 5 elevational and plan views of a second body with a gasket of a pressure reducer according to the state of the art.
- Fig. 6 a partially sectioned elevation view of the first body of Figure 1 and the second body of Figure 4 mounted.
- Fig. 7 a view of a detail of a recess of the first body with the gasket partially inserted.
- Fig. 8 a plan view of another first body according to the state of the art.

- Fig. 10 a cross-sectional view of the pressure reducer of Fig. 9 with cover.
- Fig. 1 a cross-sectional view of another pressure reducer according to the invention.
- Figures 1 to 5 show a first body 1 and a second body 3 of a pressure reducer according to the state of the art, specifically as described in WO 02/41938, on p. 1 1 line 26 to p. 13 line 8, Figs. 1 to 7.
- the first body 1 has a first surface 5 in which there is a recess or recess 7 that will form the conduit 9 that extends from an inlet 1 1 to an outlet 13.
- the second body 3 has a gasket 15 superinjected on a second surface 6.
- Figure 6 shows the assembly of the first body 1 and the second body 3 mounted, with the gasket 15 forming the seal.
- the gasket 15 is partially inserted into the groove or recess 7, as shown in Figure 7.
- Figure 8 another first body 1 of a pressure reducer is shown. according to the state of the art with a different geometric arrangement of the conduit 9.
- FIG. 9 A cross-sectional view of a pressure reducer according to the invention is shown in Figure 9.
- the pressure reducer comprises a first body 1 which, in general is substantially equal, to the first body of the pressure reducers according to the state of the art. The difference lies in the second body 3, which is directly attached to the first body 1 without any additional element between them.
- the second body 3 is attached to the first body 1 by means of a weld bead 17 that runs both sides of the conduit 9 from inlet 1 1 to outlet 13.
- FIG. 10 A cross-sectional view of another pressure reducer according to the invention is shown in Figure 10.
- This pressure reducer is, in principle, the same as the pressure reducer of Figure 9, but includes a cover 19 covering the second body 3.
- This cover 19 does not collaborate in the definition of the conduit 9 or in the tight seal of the It is a protection of the second body 3.
- FIG. 1 Another pressure reducer according to the invention is shown in Figure 1 1.
- the second body 3 is of high thickness which makes it more rigid and robust, so it is no longer advisable to include a protective cap.
