Detailed Description

The utility model relates to a pipe fixing device, in particular to a fixing patch for a medical infusion pipe. A preferred embodiment of the present invention will now be described in detail with reference to the accompanying fig. 1-10. The following description is merely exemplary in nature and is not intended to limit the present disclosure or the application.

Fig. 1 to 4 show a first preferred embodiment of the present invention, in particular, fig. 1 shows a catheter fixing patch 1 according to a first preferred embodiment of the present invention; FIG. 2 shows a state change diagram of the catheter fixation patch 1 of FIG. 1; figure 3 shows a view of the catheter fixation patch 1 of figure 1 in use, including the catheter 2 to be fixed; fig. 4 shows another state of use of the catheter fixing patch 1 of fig. 1, including the catheter 2 to be fixed.

As shown in fig. 1, the catheter fixing patch 1 is generally square in shape, and generally includes a positioning body 12 and two wings 14, wherein the positioning body 12 includes a first region 121 in the middle and second regions 122 extending from the first region 121 to both sides in a first direction a, the two wings 14 are provided on both sides of the first region 121 in a direction perpendicular to the first direction a as shown in the drawing, specifically, the first region 121 and the two wings 14 are cut apart by a certain length — two first cut lines 140 as shown in fig. 1, so that the wings 14 extend from the second region 122 of the positioning body 12 and have free end portions 144 extending freely independently of the first region 121 of the positioning body 12, specifically, as shown in the drawing, the wings 14 and the first region 121 are separated from each other and offset from each other without overlapping each other; also, the second region 122 of the positioning body 12 further includes two overlapping regions 141, the two overlapping regions 141 are also provided on both side portions of the first region 121 in a direction perpendicular to the first direction a as shown in the drawing, each overlapping region 141 is provided opposite one wing portion 14, and a notch 123 is provided between the opposite overlapping region 141 and the wing portion 14, so that: in the extended condition of the positioning body 12 (the non-use condition shown in figure 1), the notch 123 spaces the overlapping area 141 from the wing 14.

Preferably, as shown in figure 1, the two wings 14 extend in opposite directions on both sides of the catheter securement patch 1, and correspondingly, the two overlap regions 141 form a diagonal arrangement in the catheter securement patch 1. It will be appreciated that the two wings and the two overlapping areas cooperating with the wings may also be provided at the same side (upper or lower) of the catheter securement patch, respectively, whereby the two wings may extend in the same direction on both sides of the catheter securement patch.

Preferably, the catheter fixing patch 1 is made entirely of medical tape by special cutting, and alternatively, the catheter fixing patch 1 may be made of any other material capable of being adhered, affixed, adsorbed and fixed to a predetermined position (for example, a body part of a patient, etc.) in a use environment.

Fig. 2 shows a state change diagram of the catheter fixing patch 1 in fig. 1, in which the catheter fixing patch 1 is not fixed to a catheter, but is in a state in which the catheter is to be fixed. As shown, the first region 121 of the positioning body 12 may be bent to form a channel for the conduit 2 to be fixed to pass through to fix (e.g. adhesively fix) the first region 121 to the conduit 2, the second region 122 of the positioning body 12 (including the overlap region 141) remains in a stretched state and may be adhered to a predetermined position in the use environment, and the notches 123 between the overlap region 141 and the wings 14 are made up by the bending of the first region 121 so that the wings 14 are close to the respective overlap regions 141, thereby enabling the wings 14 to be overlap-adhered to the respective overlap regions 141 — as shown in fig. 2, the overlap regions 141 may be completely covered by the free ends 144 of the wings 14. It will be appreciated that the wings 14 and their respective overlapping areas 141 may be of different sizes, depending on the application, so that in use the wings 14 may also cover only a portion of the overlapping area 141 adjacent to the wings 14, and not the outer portion of the overlapping area 141 remote from the wings 14.

Fig. 3 shows a view of the catheter fixing patch 1 of fig. 1 in use, including the catheter 2 to be fixed. In use, the conduit 2 is arranged along a direction of the positioning body 12 perpendicular to the first direction a, the first region 121 of the positioning body 12 is bent to be arranged around the conduit 2 from one side of the conduit 2 and adhesively secured to the conduit 2, the second region 122 of the positioning body 12 (including the overlap region 141) is adhered to a predetermined position in the environment of use, and at least a portion of the free end 144 of the wing 14 is capable of overlap-adhering to the respective overlap region 141 (in fig. 3, the overlap region 141 is covered by the wing 14 and is not visible) to be secured to said predetermined position. Preferably, the overlap area 141 and the wings 14 are dimensioned such that: in use, the free ends 144 of the wings 14 can be flush with the respective overlap regions 141 and the sides of the wings 14 are flush with the sides of the respective overlap regions 141, i.e. when the free ends 144 of the wings 14 are in overlapping engagement with the overlap regions 141, the outboard transverse edges and the outboard vertical edges of the free ends 144 of the wings 14 are substantially aligned with the outboard transverse edges and the outboard vertical edges, respectively, of the overlap regions 141.

Preferably, in the embodiment shown in the figures, for the sake of aesthetics and ease of separating the free ends 144 of the wings 14 from the overlapping areas 141 overlapped together, the corners of the free ends 144 of the wings 14 are configured as right angles and the four corners of the positioning body 12 (excluding the wings 14) are configured with rounded chamfers, so configured that: when the free end 144 of the wing 14 is brought into engagement with the overlap region 141, the right angle corner of the free end 144 of the wing 14 extends beyond the rounded corner of the overlap region 141, thereby further facilitating separation of the free end 144 and the overlap region 141 from one another when the free end 144 of the wing 14 is removed from the overlap region 141. It is to be noted here that this configuration is not in contradiction to the "flush" described above, which is intended to mean that the lateral transverse edge and the lateral vertical edge of the free end portion 144 of the wing 14 are generally aligned with the lateral transverse edge and the lateral vertical edge, respectively, of the overlap region 141, respectively, whereas the effect of the local rounding is negligible, and, alternatively, the four corners of the positioning body 12 (excluding the wings 14) may also be all right angles without rounded corners, it is thus possible to perfectly align the lateral transverse edge and the lateral vertical edge of the free end portion 144 of the wing 14 with the lateral transverse edge and the lateral vertical edge, respectively, of the overlap region 141, which can be chosen flexibly according to the actual application, for example, it is also possible to provide the free ends 144 of the wings 14 with rounded chamfers and to position the four corners of the body 12 (excluding the wings 14) at right angles.

By providing the wing part 14 with the above configuration, the catheter fixing patch 1 can restrain and position the catheter 2 from the circumferential direction of the catheter 2, thereby better preventing the catheter 2 from being loosened; and more preferably, by the design that the wing part 14 is fixed in the overlapping and bonding way with the overlapping area 141, the wing part 14 can further fix the second area 122 including the overlapping area 141, so as to prevent the second area 122 of the positioning body 12 from being released, thereby overcoming the defect that the common medical adhesive tape is easy to be released without repeatedly or multiply bonding the adhesive tape to prevent the release as in the prior art.

It can be seen that, compared with the conventional general medical adhesive tape, the catheter fixing patch 1 according to the present invention has an elaborate design configuration so as to more firmly fix the catheter without being easily released; compare with other pipe fixing paster among the prior art, according to the utility model discloses a pipe fixing paster 1 simple structure and it is very convenient to use, can conveniently fix the pipe of various types and size, has very high cost-effectiveness.

Furthermore, fig. 4 shows another state of use diagram of the catheter fixing patch 1 in fig. 1, including the catheter 2 to be fixed. In fig. 4, the wings 14 extend in a direction perpendicular to the conduit 2 (first direction a) and are lap-bonded to the respective lap areas 141, similar to that shown in fig. 3, except that the free ends 144 of both wings 14 do not both cover the two respective lap areas 141, but rather that a portion of the free end 144 of one of the wings 14 (the upper wing in the figure) covers the respective lap area 141 and a portion of the free end 144 of the other wing 14 (the lower wing in the figure) is covered by the lap area 141 (only one corner of the free end 144 of the lower wing 14 in the figure is visible). Obviously, this method of use can also serve to reinforce the fixation as described above. Furthermore, it will be appreciated that it is also possible, in use, for at least a portion of the free ends 144 of both wings 14 to be covered by both overlap areas 141. Alternatively, in the above embodiment, although only a portion of the free end 144 of the wing 14 overlaps the overlap region 141, in practical applications, the wing 14 may completely overlap the overlap region 141 — that is, the entire overlap region 141 of the wing 14 is covered or the entire overlap region 141 of the wing 14 is completely covered, which may be achieved by adjusting the size of the wing 14 and the overlap region 141.

Preferably, as shown in fig. 1 to 4, the two wings 14 of the catheter fixing patch 1 are disposed on both sides of the first region 121 in a direction perpendicular to the first direction a, and the two overlapping regions 141 are disposed on both sides of the first region 121 in a direction perpendicular to the first direction a and are disposed one-to-one opposite to the two wings 14; and more preferably, two wings 14 are provided on either side of the conduit 2 and two overlapping areas 141 are also provided on either side of the conduit 2, respectively, whereby the conduit 2 can be forced more evenly without being easily displaced, it being understood that alternatively, two wings 14 may be provided on the same side of the conduit 2 and two overlapping areas 141 may be provided on the same side of the conduit 2.

Also, as previously described, a length, such as the two first cut lines 140 shown in fig. 1, is cut between the first area 121 and the two wings 14, such that the wings 14 extend from the positioning body 12 and are free to extend independently of the first area 121 of the positioning body 12. It should be understood that for catheters of different shapes and thicknesses, the lengths of the two first cutting lines 140, i.e. the lengths of the cut between the first region 121 and the two wings 14, can be set as desired, so as to increase or decrease the area of the first region 121 that can be bent to wrap the catheter, and to keep the wings 14 free to stretch independently of the first region 121 of the positioning body 12; also, likewise, the notch 123 between the overlap region 141 and the wing 14 can be sized as desired, so as to adjust the area of the first region 121 and keep the overlap region 141 free to stretch independently of the first region 121; even more, the notch 123 may extend from the wing 14 all the way to the edge of the second region 122, so that there is no overlap region 141, and the wing 14 is directly adhesively secured to a predetermined location (e.g., a body part of a patient) in the environment of use, as in the second embodiment of the present invention described below.

Fig. 5 to 7 show a second preferred embodiment according to the present invention, wherein fig. 5 shows a catheter securement patch 1' according to the second preferred embodiment of the present invention; FIG. 6 shows a state change diagram of the catheter fixation patch 1' of FIG. 5; and figure 7 shows a view of the catheter fixing patch 1' of figure 5 in use, including the catheter 2 to be fixed.

The catheter fixing patch 1' of this embodiment has substantially the same structure as the catheter fixing patch 1 of the foregoing embodiment, and differs only in that: the catheter securement patch 1 'does not include the overlap region 141, i.e., as shown in fig. 5-7, the notch 123' extends from the wing 14 'all the way to the edge of the second region 122', and the wing 14 'is cut away from the first region 121' of the positioning body 12 'by the first cut line 140'. In use, a first region 121 ' of the positioning body 12 ' is bent to be arranged around the catheter 2 from a first side (front side) of the catheter 2 and adhesively secured to the catheter 2, a second region 122 ' (without a lap region) of the positioning body 12 ' is adhered to a predetermined location in the use environment, and the wing 14 ' can extend at the other side (back side) of the catheter 2 opposite to the first side and be secured directly to said predetermined location. By providing the wings 14 'with the above-described configuration, the catheter fixing patch 1' is also able to restrain and position the catheter 2 from two opposite sides of the catheter 2, so that the catheter 2 can be better prevented from coming loose.

Fig. 8 to 10 show a third preferred embodiment according to the present invention, wherein fig. 8 shows a catheter fixing patch 1 "according to the third preferred embodiment of the present invention; FIG. 9 shows a state change diagram of the catheter fixation patch 1 "of FIG. 8; and figure 10 shows a view of the catheter fixing patch 1 "in figure 8 in a state of use, including the catheter 2 to be fixed.

The catheter fixing patch 1 ″ of this embodiment has substantially the same structure as the catheter fixing patch 1 of the first embodiment, except that: the catheter securement patch 1 "does not include the notch 123, i.e., as shown in fig. 8-10, in the unused state of the catheter securement patch 1", the wings 14 "extend all the way to the opposing overlap areas 141", the wings 14 "and the overlap areas 141" are separated from each other by the second cut line 150 only but remain in abutment, and the wings 14 "are cut apart from the first area 121" of the positioning body 12 "by the first cut line 140". In use, a first region 121 "of positioning body 12" is bent to be arranged around conduit 2 from one side of conduit 2 and adhesively secured to conduit 2, a second region 122' (having an overlap region 141 ") of positioning body 12" is adhered to a predetermined location in the use environment, and wings 14 "can extend and overlap to respective overlap regions 141" on the other side of conduit 2 opposite to the first side. In this case, due to the long length of the wings 14 ", the wings 14" may be out of the overlapping area 141 "in use — for the sake of illustration, in this embodiment one of the two wings 14" overlaps under the corresponding overlapping area 141 ", but this does not affect the use, as long as the purpose of restraining and positioning the catheter 2 is achieved. In addition, the respective sizes of the overlap area 141 and the wing part 14 may be also appropriately adjusted according to the requirements.

In addition, it should be understood that although in the above embodiments, the first region 121 ', and the first region 121 ″ may be provided to be capable of being adhered, attached, and adsorptively fixed to the catheter 2, the first region 121, 121', 121 ″ may also be provided not to have any adhesion, attachment, adsorptivity or effect, but to be arranged around the catheter 2 only from one side of the catheter 2 to captively position the catheter 2. While such a configuration may not be optimal, in some cases (e.g., situations requiring frequent catheter replacement, etc.), such a configuration may facilitate catheter replacement and catheter securement patch reuse.

Various embodiments can be further devised by combining or modifying different embodiments and various technical features in different ways, all within the scope of the present invention.

The catheter securement patch according to the preferred embodiment of the present invention has been described above in connection with the specific embodiment. It will be understood that the above description is intended to be illustrative and not restrictive, and that various changes and modifications may be suggested to one skilled in the art in view of the above description without departing from the scope of the invention. Such variations and modifications are also intended to be included within the scope of the present invention.
