Description

  The present invention relates to a cannula holder, and more particularly, to a cannula holder having an improved tensile strength of a band for fixing a cannula to a neck.

  The cannula is a tracheostomy tube and a cannula holder is used to secure the cannula to the neck. The principal part of the conventional cannula holder is shown in FIG. As shown in FIG. 4, the tip of the cannula holder is composed of a clip band 11 and a holder main body portion 12, the clip band 11 is a male member of a hook-and-loop fastener, and the holder main body portion 12 is a female member having a hook-and-loop fastener surface. is there. The sticking band 11 is inserted into the through hole 3 of the cannula 1, folded back and joined to the surface of the holder main body 12. (See Patent Document 1)

  As shown in the dotted circle in FIG. 4, the fastening band 11 and the holder main body 12 are joined by sewing. According to Patent Document 1, for example, the holder main body portion 12 is formed of a two-layer product having a female member having a hook-and-loop fastener on the outside and a sponge sheet on the inside, and both are thin and soft materials. On the other hand, the sticking band 11 is a male member of a hook-and-loop fastener, and is a resin material that can be bent, but is a slightly hard material. Therefore, when the cannula holder is wound around the neck, it is not tightened with such a large force. However, if the cannula holder is used many times, the holder main body 12 is broken as shown in FIG. Sometimes peeled off.

U.S. Pat. No. 4,331,144

  The objective of this invention is providing the cannula holder which can improve the tensile strength of a holder main-body part.

  A cannula holder according to the present invention comprises a male member of a hook-and-loop fastener, one end of which is inserted into a through-hole of the cannula and folded back, and a female member of a hook-and-loop fastener is formed on the outside and is surface-joined with the sticking band. It consists of a layer containing an outer cloth, a sponge sheet inside, and a cotton cloth inside, and both ends in the width direction are stitched together with cotton cloth tape, and the width is gradually reduced toward both ends in the length direction, And a holder main body portion to which the other end of the clip band is sewn at both ends having the same width as the width of the clip band.

  The cotton cloth tape is sewn on the outer surface of the holder main body portion when overlocked.

  According to the cannula holder of the present invention, since both ends of the holder body in the width direction are stitched together with a cotton cloth tape, and the tie band is sewn here, it can withstand a tensile load of about 90 N. It is possible to prevent breakage easily. Overlock stitching has a rounded edge that softens the skin, prevents fraying from the edge and peeling of the layer structure, and also hides the internal sandwich structure from the outside, and has the effect of giving a sense of quality. Cotton cloth tapes that are sewn together by over stitching can prevent the holder body from easily extending. In addition, the width of the holder main body is gradually reduced toward both ends in the length direction, and the width of both ends is made the same as the width of the clasp band, so that the tensile load of the clasp band is applied to both sides of the holder main body in the width direction. Can be dispersed on two cotton cloth tapes.

  Since the cotton cloth tape is sewed on the outer surface of the holder main body (here, overlock sewing), it is possible to avoid a decrease in the texture due to the protruding edge as compared with the case of sewing on the inner surface of the holder main body.

1 is a perspective view of a cannula holder according to the present invention. It is a perspective view of the 1st band shown in FIG. It is AA sectional drawing of FIG. It is a perspective view of the conventional cannula holder.

  Hereinafter, a cannula holder according to the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a cannula holder 100 according to the present invention. In FIG. 1, the cannula 1 is a tracheal tube provided with through holes 3 on both sides. It is the cannula holder 100 that is inserted into the patient's trachea and secured to the patient's neck. The cannula holder 100 includes a single band and a double band. In this embodiment, the description will be made with two bands. As shown in FIG. 1, there are two bands, a first band 10 and a second band 20, which are detachably connected.

  The first band 10 includes a sticking band 11, a holder main body part 12, a rubber band 13, and a connecting part 14. One end of the sticking band 11 is inserted into one through hole 3 of the cannula 1 and folded, and the other end is sewn to the holder main body 12. Therefore, it can be bent to the extent that it is folded back, and is made of a resin that is thin and hard enough to allow the through hole 3 to pass through. The sticking band 11 is a male member of a hook-and-loop fastener in which a number of hook-like hooks are provided on one surface. The holder main body portion 12 is made of a soft material, and the outer side is made of a female member of a hook-and-loop fastener provided with a number of loop-shaped fibers entangled with the hook. The wrapping band 11 folded back here is surface joined to the holder body 12. The holder main body 12 is overlocked (indicated by reference numeral 2) at both ends in the width direction. One end of the rubber band 13 is attached to the holder body 12. Thereby, when the cannula holder 100 is attached to the patient's neck, it can be held in an appropriate degree of tightening. A connecting portion 14 made of a male member of a hook-and-loop fastener is attached to the other end of the rubber band 13. The connecting portion 14 is surface bonded to the outside of the holder main body portion 22 of the second band 20.

  The second band 20 includes a clip band 21 and a holder main body 22. One end of the sticking band 21 is inserted into the other through-hole 3 of the cannula 1 and folded, and the other end is sewn to the holder body 22. The sticking band 21 is a male member of a hook-and-loop fastener in which a number of hook-like hooks are provided on one surface. The holder main body portion 22 is made of a soft material, and the outer side is made of a female member of a hook-and-loop fastener provided with a number of loop-like fibers entangled with the hook. The glued band 21 folded back here is surface joined to the holder body 22. The holder main body 22 is stitched at both ends in the width direction. The 1st band 10 and the 2nd band 20 are connected by the connection part 14 so that attachment or detachment is possible.

  FIG. 2 is a perspective view of the first band 10 shown in FIG. The holder main body 12 has a width that is gradually reduced in the length direction, and the width of one end is the same as the width of the clip band 11. Similarly, although not shown, the width of the holder main body portion 22 is gradually reduced in the length direction, and the width of one end is made equal to the width of the clip band 21.

  FIG. 3 is a cross-sectional view taken along the line AA of FIG. The holder body 12 is composed of three layers of an outer cloth 5, a sponge sheet 6, and a cotton cloth 7 made of a female member of a hook-and-loop fastener from the outside to the inside. The number of layers may be further increased without being limited to three layers. The cotton cloth 7 was rough and breathable and had good skin feel. At both ends in the width direction, over stitching 2 is performed together with the cotton cloth tape 4. This cotton cloth tape 4 used had a fine eye and strength and did not stretch. As shown in FIG. 2, when the tie band 11 is sewn to the holder main body 12, the tie band 11 is combined with two cotton cloth tapes 4. That is, even if the sticking band 11 is pulled, the force can be distributed to the two cotton cloth tapes 4. The holder body 22 is the same as the holder body 12. The overlock stitch 2 may be performed on portions other than the both ends in the width direction of the holder main body portions 12 and 22 (for example, the end of the sewn portion of the rubber band 13). Further, a thermocompression bonding tape may be used instead of the cotton cloth tape.

  The present invention is suitable as a cannula holder having a tensile strength.
