Body for attaching wires to a bundle

The invention relates to a member for bundling separate wires, which consists of 5 body parts with one or more grooves, in which groove one or more wires can be placed.

Usually, the wires used in connection with different monitors run separately along the floors, causing 10 inconvenience to people walking in their midst. In addition, such an environment gives an uncomfortable and poor overall impression. An attempt has been made to solve this problem simply by tying the wires together at certain intervals, for example with a strap or string. However, this work is 15 time consuming and cumbersome. In particular, the problems of such a solution arise when one wire has to be removed from several other wires. Then all the fasteners must be removed and later again cumbersome joining.

20 In the bundling of electric wires, a solution has also been applied in which a plurality of bundled wires are placed in a plastic tube, the side of which can be opened along its entire length by tearing the flange running along the side · ;;; 2 5 open. The other edge of the plastic tube thus extends over the other edge, whereby the opening on the side is covered. These edges are still fastened to each other in one way or another, e.g. with glue. The problem with this type of solution is its impracticality, because first the side of the plastic hose has to be opened and only then can some cable be removed or taken inside the pipe. The edges of the side are then fastened together. It has not been possible to remove or insert any electrical cord from the plastic tube other than at the ends of the plastic tube.

In some cases, even obtaining a separate plastic hose inside which the existing wires are placed, or the means necessary to connect the various wires at the very moment when they are needed, 5 can be difficult, requiring time and effort.

In connection with patient monitoring monitors, hoses are needed connecting the breathing tube leading to the patient and the actual analyzer 10, where the material used depends on the intended use. If the hoses use the same base material, their inner surface must be coated with a special material. The tube carrying the samples from the breathing tube must not absorb the anesthetic gases used to anesthetize 15 patients, as the gas absorbed into the tube causes errors in measuring their concentrations in the measuring chamber included in the analyzer. Usually the PVC hose is coated with Teflon to withstand anesthetic gases. In the same context, when measuring anesthetic gas concentrations, it is often also desired to study other things, such as gas flows. This, in turn, requires two tubing, which is often routed from the same location from the patient's breathing tube as to the analysis equipment of the patient's breath sample. These pressure hoses are not required to have the same characteristics as gas sample hoses. For this reason, one double hose and a separate sample hose are often used today. However, in the operating room, each extra hose has 30 procedures working there complicating the procedures. Replacing a double hose and a single sample hose with a triple hose in which all three hoses are cast together would be an unsatisfactory solution, as coating one or more hoses in a triple hose is difficult 35 and expensive.

It is an object of the present invention to obviate the above problems. The aim is to provide a means for attaching the wires 5 to the bundle as simple as possible for the user. It is a further object of the invention to provide such a member for bundling wires, from which any of the bundled wires can be inserted and removed from connection to the member at any stage other than at the ends of the member without special machining operations. It is also an object of the invention to provide a means for bundling lines leading to a patient monitoring monitor for anesthesia, such as a gas sample line and a double line for flow measurement.

The characteristic features of the device according to the invention are set out in the claims.

The invention is based on the fact that the separate wires are stapled in a bundle by fastening them to a special body part having one or more grooves for fastening. A wire is placed in the groove from its open side, the distance between the edges of which is less than the cross-sectional diameter of the wire to be inserted from this side. Thus, either the edge of the open side of the groove or the wire to be placed in the groove must be flexible. The wire is obtained in the groove by first placing the wire on the open side of the groove and pressing the wire against this side 30, whereby the more flexible party, i.e. either the edge or the wire, gives in enough for the wire to press into the groove. Since the distance between the edges of the open side of the groove is smaller than the cross-sectional diameter of the wire inside, the wire also remains in the groove without other 35 separate measures. Removing the cable from the groove «87395 is done simply by pulling the cable away from the body part, whereby again the edge of the open side of the groove or the cable is flexible, i.e. gives up.

5 One wire can be placed in the groove most preferably, but several are also possible. If several wires are intended to be placed in one groove at the same time or one wire is intended to be placed in the groove at a time, but the size of the wire can vary from large to small, there could preferably be some very flexible material inside the groove which would be relatively easily compressed. This would have the advantage that the wires remain substantially immobile even if the cross-sectional area of the groove is larger than the corresponding area occupied by the existing wire or wires.

For one reason or another, it is not always possible to build a solution at the manufacturing stage where all the wires are fixed in one and the same body part. Sometimes it may be advantageous to manufacture a body part which already contains a few wires integral with the body part and in which the body part also has a groove in which a separate hose, for example made of a different material, can be placed.

Such a solution is particularly advantageous when several wires have to be stapled together and when a chemical compound has to be transported along at least one wire, as a result of which the material of one wire must be different from other separate wires.

The invention will now be described in more detail with reference to the accompanying patent drawings, in which Fig. 1 schematically shows a member 35 according to the invention in an operating environment, Fig. 2 shows a perspective view of a member a cross-section of an alternative member according to the invention, Figure 5 shows a cross-section of an alternative member according to the invention.

In Figures 1, the patient is connected to the ventilator 2 via a breathing tube 1. A connector 3 is connected to this breathing tube for taking gas samples and detecting the flow in the tube. The connector 3 communicates with the analyzer 4 via a member 5 according to the invention. In this case of the figure, one line 6 is preferably required for sampling and lines 7 and 8 for performing the flow measurement. Line 6 requires different characteristics than lines 7 and 8.

Figures 2 and 3 show in more detail the structure of the member 5 according to the invention. The member 5 consists of a body part 9 with a groove 10. On the side of the groove there is an opening 11 from which a separate wire 6 is pressed into the groove. The distance between the edges 12 and 13 on the opposite sides 25 of the opening is smaller at a narrower point than the cross-sectional diameter of the wire 6. When the wire 6 is pressed into the groove 10, the edges 12 and 13 surrounding the opening 10 preferably give way, later trying to return to their original state after the wire has left the opening 30. Another advantage of such a solution is that the cable 6 can be inserted into and out of the groove not only from the ends of the body but also from any point of the body through the opening 11.

The body part 9 has fixed wires 7 and 8 on both sides of the groove 10. In this case of Figure 1, the body portion is preferably a polymer-based material such as polyvinyl chloride, which is useful in performing flow measurements. Instead, the line 6 carrying breath samples may also be made of a PVC-based material, but the inner surface of the line that comes into contact with the anesthetic gases should then be coated with a material such as Teflon, which does not absorb these gases.

Figure 4 is a cross-sectional view of an alternative structure to Figure 3. In this case, the body part has a plurality of grooves 10 for fixing a plurality of spaced-apart wires 15 to the same bundle.

When placing different wires with different cross-sectional diameters or shapes in the same groove at different times, or several wires simultaneously in the same groove, it is advantageous if the wire is tightly in the groove so that it cannot slide inside the groove in the longitudinal direction of the body. In the solution shown in Fig. 5, a filling 14, which is a flexible material such as cellular plastic, is placed in the groove 10. This padding allows, if necessary, 25 to give way, allowing wires larger than the free space inside the groove to be placed in the groove. Thus, wires smaller in cross-sectional area over the entire groove, which includes the infill and other free space in the groove, also remain immobile in the groove.
