CS260195B1 - Protective sleeve for stump of amputated limb, made of one-piece knit - Google Patents

Abstract

A protective sleeve for an amputated limb stump with a narrower hose edge, which is formed in a solid grip in the form of a full row of loops. The expanded hose rows additionally contain one incorporated filler loop and one incorporated filler eyelet to fill the holes in the shaping traces at the edges of the expanded rows. The protective sleeve can be formed from at least two sets of threads, at least one of which contains hydrophobic threads and at least one hydrophilic threads.

Description

The invention relates to a protective sleeve for a stump of an amputated limb, which is made in the form of a hose, the diameter of which is determined by the shape of the stump, for example of the thigh, elbow or leg. The closed lower narrower edge of the knitted hose forms the bottom of the sleeve, while the open upper wider edge is adapted for easy insertion of the sleeve.

Commonly used sleeves are manufactured in the form of tubular shaped knitted cones with a closed narrow end on one side. Due to the special purpose of use, their utility values are subject to high demands, especially in terms of their shape, the material used, the appearance and the careful design.

The process for making known single-sleeve sleeves involves knitting a hose on a flat knitting machine, starting from the widest point of the hollow fabric at one end of the hose and continuing towards the narrowest point of the hollow fabric at the other end of the hose. The shaping of the hose between these end points is accomplished by sequentially transferring or hanging the stitches at both edges of the knitted width, depending on the desired final sleeve shape. The gradual narrowing of the hose is effected by moving one loop from the outer needle either to the adjacent needle, i.e. by transferring, or to a needle lying in the opposite needle bed, i.e. by hanging the stitches. In this way, it proceeds to the narrowest point of the hose, which ends with one loose loose line around and several other rows of yarns of different colors, thus completing the knitting process of one sleeve. This is followed by a ready-made finish which involves closing the knitted hose at its narrowest point by manually picking up and joining the place on the chaining machine to produce a double seam at this sleeve location, and placing the knitted fabric at its widest point, for example on an overlapping sewing machine. However, the described method of manufacturing the sleeves is laborious and demanding in terms of reliability. When picking up, double eyelets are formed which strengthen the sleeves in these places. This results in losses and production capacity of the knitting machine due to interruption of knitting or so-called empty passes of the machine slide.

In order to overcome these drawbacks, the construction and method of producing a shaped protective sleeve on a stump of an amputated limb in the form of a hose of gradually varying diameter is directed. Shape lines are formed at the edges of the hollow hoses where the lines extend. The essence of the invention is that the narrower edge of the hose is formed from a full row of fixed grip loops, while the wider edge is made by a ready-made treatment, for example by insertion into a hollow skirt. The extended rows of the one-piece knitted fabric are filled in the holes of the shaping tracks in the edges of the extended rows with an additional filling loop and an integrated loop, which fill the holes and uniformize the knitted fabric in the extended rows. In a preferred embodiment, the protective sleeve is knitted from at least two sets of threads, of which at least one set comprises hydrophilic threads and at least one hydrophobic thread. The surface of one side of the knitted fabric, for example its face side, may be formed from at least one set of hydrophilic threads or also hydrophobic threads or threads containing predominantly one of these materials.

The protective sleeves according to the invention are knitted on a double knitting machine in such a way that, after being caught on the needles of both machine beds, hollow one-row rows are knitted sequentially and sequentially to the catch, i.e. from the narrowest point of the hose at its lower edge its upper edge. This expansion is accomplished by the sequential addition of knitting needles on both sides with simultaneous entanglement of the loops and stitches on the outer needles of the opposite needle bed, which is enabled by controlling the knitting machine with a single choice of knitting needles. Upon reaching the widest point of the hose, it is closed by knitting several rows of knitting, preferably from a different colored yarn, whereupon the ends of the knitting on the left and right edges of the knitting needle are dropped and the remaining number of needles in the middle of the knitting is formed. The knitting cycle is preferably continuous, i.e. a further sleeve follows the evaporation line and the knitting continues again by catching.

The protective sleeve according to the invention exhibits higher qualitative and utility properties compared to known products. The knitting process is simplified with increased performance of the knitting machine. It is also essential to simplify the finishing process while reducing labor. The major difference in the manufacture of the sleeve compared to the known methods lies in particular in the fact that the opposite method is used, ie it starts at the narrower end of the sleeve and the hose expands and ends at the widest point during knitting. Shaping the hose is accomplished by expanding, i.e., simply adding knitting needles at the edges of the knitted width. Since in this case it is a special way of shaping a single-knitted tubular knitted fabric, with the requirement to fill the holes, which would be created simply by adding the needle, the possibility of entangling the loops first and in the next row stitches was added. In this type of article, the knitted fabric expands by only one needle in succession, with the tendency to extend and the shape of the sleeve depending on the use and size of the sleeve.

The outer distinguishing feature is the smooth, simple edge of the narrower end of the sleeve formed by the catch. Simply adding needles on a knitting machine is considerably easier and therefore more reliable than slacking or transferring stitches. The simplification of the knitting process is emphasized by being

260193 with the knitting of the following sleeve starting at a smaller width than the previous product is finished, the knitting time will be shortened while saving the textile material. There is also a simplification of the ready-made finishing of the sleeves, which in this case consists only in establishing the upper edge of the sleeve.

The principle of the invention and a more detailed explanation of its nature are apparent from the attached two drawings which show in FIG. 1 a view of an exemplary embodiment of a shaped protective sleeve with traces of shaping at both edges and FIG.

Giant. 1 shows the protective sleeve 1 after knitting is finished on the needles of a flat knitting machine (not shown), in the knitting phase of the following protective sleeve 1 ‘, shown in the upper part of FIG. 1. The smooth lower edge 2 of the protective sleeve 1 is formed by a catch in its narrowest position. The lower part of the protective sleeve 1 exhibits a steep course of the forming lines 4 in both edges of the extended rows 3. Towards the wider upper edge of the protective sleeve

Also, the number of expanded rows 3 and thus the shaping stop 4 is reduced proportionally. In the end portion 7, the width of the protective sleeve 1 has stabilized at its wider upper edge with the largest final diameter. The end portion 7 is followed by a braid 8 whose right edge 9 and left edge 10 coincide with the needles before knitting the evaporator row 11. Width of evaporation line

II corresponds to the width of the catch and thus the narrowest lower edge of the following protective sleeve Γ. The detail of the weave of the single knitted fabric is shown in Fig. 2, with the expanded line 3 for the purpose of illustrating the course of the weave with respect to the situation in both edges of the protective sleeve 1 turned. In the context of the present invention, the opening formed by the conventional method of expanding the knitted fabric is filled in the expanded row 3 successively with a filling loop 5 and a filling loop 6.
