Definitions
- the invention relates to a disposable that is suitable for application in a device for heating a physiological fluid, in particular blood, and is provided with a conduit for conducting fluid, which conduit comprises con- duit sections that are arranged next to each other and bends that connect the conduit sections.
- a device for heating a physiological fluid using such a disposable is described in applicants' earlier patent application NL-A-1015999, which is not pre-published.
- the conduit is accommodated in an element that can be exchanged after use as disposable.
- the conduit is further embodied such that at least one side is permeable to infrared radiation to facilitate heating by means of, for example, an infrared lamp or another source of infrared radiation.
- the disposable is characterized in that in at least one of the bends a first turbulence-inducing obstruction is placed, preferably a baffle having a height of at least approximately 20% of the height of the conduit at the position of that baffle.
- a baffle causes a turbulence in the fluid stream such as to prevent the occurrence of hot spots .
- the invention is certainly not limited to a baffle of this kind, rather it is aimed at such obstructions in general that are suitable for producing sufficient turbulence.
- baffles or baffles.
- An important advantage of the embodiment with baffles is, moreover, that the disposable can be manufactured simply and at limited costs by injection moulding.
- the first baffle (the first obstruction) is optimally effective if the same has a top edge which, viewed from the outer side of the at least one bend, slopes down- ward.
- the first baffle is placed in the at least one bend at an angle in relation to the local direction of flow.
- the effectiveness of the measures proposed in ac- cordance with the invention is further assisted by embodying the bends succeeding the conduit sections such that their width is substantially the same as their height, and by placing the first baffle in the at least one bend near the connection with the conduit portion preceding this bend and in its extended direction. More preferably said bends are embodied with a circular cross section. This sustains the turbulence in the bends as effectively as possible.
- the second baffle also has a top edge which, viewed from the outer side of the at least one bend, slopes downward, and is this second baffle also placed at an angle in the at least one bend. Viewed in the direction of flow of the bend, the second baffle is placed after the first baffle, in a manner so as to be positioned in the curve and exactly before the part of the bend that is succeeded in its extended di- rection by a further conduit section.
- the drawing shows in - Fig. 1 a schematic illustration of the administration of blood to a patient
- FIG. 1 a cross section of the disposable that can be applied in the heating device used in Fig. 1.
- Identical reference numbers in the figures indicate identical parts.
- a schematic illustration of blood or another physiological fluid being administered to a patient is shown.
- the fluid to be introduced into the body of a patient 1 is contained in a storage bag 2.
- a filter 3 from where it is conducted to a heating device 4 comprising a disposable 5 in which the actual heating of the fluid takes place be- fore it is administered to the patient 1.
- this disposable 5 comprises a conduit 6 arranged in a flat plane.
- the conduit comprises conduit sections 6.1-6.10 arranged next to each other and in counterflow, and bends 6.12, 6.23, 6.34, etc., connect- ing the various conduit sections.
- bend 6.12 comprises a first baffle 7 whose height, as Fig. 3 clearly shows, is approximately half that of the conduit's height at the position of the baffle 7.
- a height of at least ap- proximately 20% of the height of the conduit is also very effective.
- Fig. 2 further shows that the bend 6.12 comprises a second baffle 8. Viewed from the outside of the bend 6.12, both the first baffle 7 and the second baffle 8 preferably have top edges that slope downward. This is clearly shown in Fig. 3. Fig. 2 shows that the first baffle 7 and the second baffle 8 are placed at an angle in relation to the bulk of the local direction of flow in the bend 6.12.
- Fig. 3 in combination with Fig. 2 further shows clearly that the conduit sections 6.1 and 6.2 are wide and shallow, while the bend 6.12 is embodied with a width that is substantially the same as the height, with the first baffle 7 being placed in this bend 6.12 near its connection with the conduit portion 6.1 and in its extended direction immediately preceding the bend. It is further preferred for the bends to be embodied with a circular cross section. However, is it difficult to manufacture this; in contrast, the embodiment in which the width and height of the bends are the same is easy to manufacture, while the turbulence in the bends is sustained very well.
- the second baffle 8 which viewed in the direction of flow of the disposable 5 succeeds the first baffle 7, is placed in the curve of the bend 6.12, just before the portion that in its extended direction forms the succeeding conduit portion 6.2.
