The term “foam material” is not intended to mean the original material forming the foam, but rather is intended to mean the solid foam product itself, in other words the synthetically produced material of cellular structure. Among other things, rubber, a rubber-plastic mixture and particularly a synthetic resin or plastic can be considered as the raw material to make the foam material. Some synthetic foam materials, which can be used, are cited in Neumuller, Otto-Albrecht: Rompp Chemie-Lexikon, Stuttgart, Francksche Verlagsanstalt [;Publisher];, 8th Edition, page 3703, under the key word “Schaumkunststoffe” [;“Synthetic foam”];. Because of the low density of the foam material, both the device for the fixing and also the medical-technical measuring device are of low mass. The longitudinal opening can be a blind hole or a through-passage opening and can be arranged in the center or eccentrically in relation to the longitudinal axis of the carrier means. Preferably, in any case, the axis of the longitudinal opening extends parallel to the axis of the carrier means. The diameter of the longitudinal opening is preferably somewhat smaller than the diameter of the smallest body part to which the measuring device is to be affixed.

<FGREF>FIG. 1</FGREF> shows a perspective view of a foam material part 1 of a carrier or carrier means of a device according to the present invention for fixing of medical-technical measuring device, particularly a pulsoximeter sensor, to a body part of a patient. The foam material part 1 has a longitudinal opening 3 extending in a longitudinal direction 2 to receive the body part. Furthermore, foam material part 1 has a transverse opening 4 extending in a straight line and essentially at a right angle to longitudinal direction 2, into which the measuring means 5 and 6 is inserted.
In the embodiment shown in <FGREF>FIG. 1</FGREF>, foam part 1, longitudinal opening 3 and transverse opening 4 are of circular cylindrical configurations. Longitudinal opening 3 extends from a frontal end of foam part 1 as far as the opposite, reverse end. Transverse opening 4 extends from a point on the covering surface near the border of foam part 1 to the diametrically opposite point on the cover surface, and thus, intersects longitudinal opening 3. The diameter of longitudinal opening 3 is somewhat smaller than the smallest body part to be received therein. The diameter of transverse opening 4 is adapted to the measuring means 5 and 6 to be inserted therein.
Foam material part 1 has four incisions or slits 7, 8, 9 and 10 originating from longitudinal opening 3 and extending at least for some distance in longitudinal direction 2, forming four segments 12, 13, 14 and 15 around the periphery 11. Incisions 7, 8, 9 and 10 extend in radial direction through at least half the thickness of foam part 1, preferably as far as a few millimeters below or within the exterior surface. The four segments are connected with one another around their exterior by a layer 16 formed of one integral piece with segments 12, 13, 14 and 15 and passing all the way around the foam material part. In the embodiment of <FGREF>FIG. 1</FGREF>, incisions 7, 8, 9 and 10 extend along the entire axial length of foam material part 1, are radially aligned in a straight line and form four identical segments 12, 13, 14, 15 with regard to their dimensions and particularly their angle extensions. In this embodiment longitudinal opening 3 is arranged in the center of cylindrical foam material part 1.
<FGREF>FIG. 2</FGREF> shows the optical electronic measuring means or sensor 5 and 6 of a medical-technical measuring device of the present invention, particularly a pulsoximeter sensor. The device includes at least one optical transmitter element 6 and at least one optical receiver element 5, which can be inserted into the ends of transverse opening 4 of foam part 1, which ends are opposite one another. For this purpose, transmitter element 6 and receiver element 5 have plug segments 17 and 18, respectively. The plug segments are cylindrical in this embodiment, but if necessary can be conical in shape, and guarantee proper guiding during insertion into foam part 1. Thus, the plug segments guarantee the desired alignment of transmitter and receiver elements 6 and 5. On each plug segment 17 or 18, a flange segment 19 and/or 20 is mounted, preferably of one integral piece therewith. Each flange segment forms a stop during the plugging in or insertion to prevent the plug segments from sinking all the way into the foam material part. The flange shape can be adapted to the exterior contour of foam part 1, in other words it can be curved. Transmitter element 6 is connected with receiver element 5 through a connecting line 21. Connection 22 connects receiver element 5 and/or transmitter element 6 with a reading and/or analysis device.
<FGREF>FIG. 3</FGREF> shows a sheathing 23 of either plastic or metal, forming a rigid casing around the carrier means and around foam material part 1. Sheathing 23 includes two half-shells 24, 25 each of which is essentially semi-cylindrical in cross section. The half-shells are connected with one another by articulation on their edges facing one another by a hinge 26 and have a hook- or catch-like closing 27 along the respective facing side edges. Half-shells 24, 25 are preferably formed of a rigid, thin plastic or metal and are elastically deformable, particularly in radial direction, for the closing or opening. Alternatively or supplemental thereto, other closing mechanisms, for example catch closings, adhering closings or adhesive closings can be inserted into hook- or catch-like closing 27. In the example shown, the complete carrier or carrier means is formed by the combination of foam material part 1 with the sheathing 23.
<FGREF>FIG. 4</FGREF> shows a similar two-part sheathing 123 conically tapering in longitudinal direction 2. This sheathing tapers in the direction toward the axial end hinge 126 allowing for folding back of one part for the insertion of a foam material part. The foam material can optionally also be conical. Hinge 126 is formed by axle journals 128 configured of one piece with the first half-shell 124. The axle journals engage in corresponding openings 129 of the second half-shell 125. First half-shell 124 is essentially semi-circular in cross section. Second half-shell 125 in cross section forms a circle segment of more than 180 degrees. Upon folding together, the first half-shell 124 connects by snapping into second half-shell 125. The cohesion in the snapped-together state is adjustable by the design of half-shells 124, 125, particularly by relative spreading of first half-shell 124 and/or by crimping of second half-shell 125.
<FGREF>FIG. 5</FGREF> shows an alternative embodiment of foam material part 101, in which longitudinal opening 103 extends eccentrically relative to the middle axis of foam material part 101. Incisions 107, 108, 109, 110 are not uniformly distributed around the opening periphery, but rather form one segment 113 much closer to the side of longitudinal opening 103 associated with the receiver element 6. Segment 113 extends, for example, over approximately a breadth of 180 degrees and has only a short radial extension. By the eccentric arrangement of longitudinal opening 103, it is guaranteed that one of the measuring means, particularly receiver element 5, engages directly on the body part or in any case is arranged to be directly thereon.
<FGREF>FIG. 6</FGREF> shows an exemplary embodiment of the carrier or carrier means, in which foam material part 201 is made up of one integral piece with casing or sheathing 223, for example, with use of integral or structural foam parts having a solid skin and a cellular core. Clamping means in the form of slotted tubes 230 and 231 are preferably formed of one integral piece with sheathing 223 on the exterior. A first slotted tube 230 receives connecting line 21 between transmitter element 6 and receiver element 5, and extends essentially around half of the peripheral surface. A second, particularly a straight slotted tube 231 extends along the exterior of sheathing 223 and receives the connection 22. Slotted tubes 230 and 231 are elastic so that they can be spread open. Allowing the connecting line 21 and connection 22 to be simply and detachably mounted on foam material part 201.
