Description

The utility model relates to the field of medicine, more specifically to devices designed to hold bandages on the foot stump after metatarsal amputation.

Bandage, cotton-gauze aseptic dressings are known, which are used in surgery for dressing wounds after metatarsal amputation (General surgery: textbook / G.P. Rychagov, P.V. Garelik and others; edited by G.P. Rychagov, P. V. Garelika - Minsk: Interpressservice, Book House, 2002 - pp. 199-200).

Disadvantages of these dressings: the duration of application and change of dressings, insufficient fixation, frequent slipping, inconvenience to use.

Known bandage on the stump of the foot, made of dressing components, sewn in the form of a bag for quick dressing (AC No. 1739994 A61F 13/00, 15.06.92).

The disadvantages of this bandage are: poor fixation, lack of variability in size, the impossibility of debridement of the wound without removing the bandage.

Known fixing bandage, consisting of a plastic tape with threaded elements for better fixation of the bandage (patent RU No. 2054917, A61F 13/00, 27.02.1996).

The disadvantages of this dressing: the complexity of the design, the impossibility of repeated use, the deterioration of blood supply.

A device for fixing medical dressings is known, which is a flexible elastic tape with spikes on its side edges (patent RU No. 2125862, A61F 13/00, 10.02.1999).

The disadvantages of this device include: the duration and inconvenience of changing the bandage, the need to use bandages, the inability to sanitize the wound.

Closest to the claimed technical solution is a fixation bandage on the stump of the foot, containing permanent and replaceable parts made of hypoallergenic woven material; while the permanent part consists of two woven tapes attached to each other with Velcro, one of which circularly encircles the stump of the foot in the tarsal area, the replaceable part is made using rubber threads and goes around the Achilles tendon and has an extension in this area; and the replaceable part - directly closes the active bandage on the stump of the foot, is a fabric circle with through semicircular perforated holes and petals with Velcro fasteners, with which it is attached to the permanent part (patent RU No. 190714 A61F 15/00, 09.07.2019).

The disadvantage of this fixing bandage is the possibility of slipping; loose fixation of the permanent part on the foot.

The technical result obtained from the use of the claimed utility model is the reduction of time and labor costs for dressings, tight fixation of the bandage on the stump of the foot, and a reduction in the amount of dressing material used.

The specified technical result is achieved by the fact that the fixator of the bandage on the stump of the foot contains a permanent and replaceable part and is made of hypoallergenic woven material, which are attached to each other. The permanent part has a heel and sole made of dense fabric, as well as a rectangular Velcro tab located on the sole, while straps with plastic fasteners are fixed on the sides of the heel. The replaceable part is a fabric circle made of hypoallergenic material with numerous through perforated holes through which antiseptic solution is dripped. On the sides of the fabric circle of the interchangeable part, there are two straps with holes and a Velcro tab located at the bottom of the fabric circle. The replacement part is attached to the permanent part with two straps, while the plastic fasteners on the straps of the permanent part are threaded through the holes on the straps of the replacement part, and the rectangular Velcro tab on the replacement part is attached to the Velcro tab on the permanent part. Through perforations located on the fabric circle of the replaceable part have a teardrop shape.

Comparison of the proposed device with others known in the field of medicine showed its compliance with the criteria of the utility model.

The utility model is illustrated by graphic material, where in Fig. 1 shows a general view of the bandage retainer in its original position; in FIG. 2 shows the permanent part of the bandage retainer; in FIG. 3 shows the replacement part of the bandage retainer.

The fixator of the bandage on the stump of the foot consists of a permanent 1 and a replaceable 7 parts. The permanent part 1 is made of dense fabric and consists of a heel 2, a sole 4, a rectangular Velcro petal 6 located on the sole 4, two straps 3 with plastic fasteners 5. The replaceable part 7 is made of hypoallergenic woven material, directly closes the active bandage on foot stump and is a fabric circle with numerous through perforated teardrop-shaped holes 11, equipped with two straps 8 and a rectangular Velcro petal 9.

In practice, the fixator of the bandage on the stump of the foot works as follows. First, the permanent part 1 is put on the stump of the foot, for this the heel of the foot is placed in the area of the heel 2; straps 3 are stretched along the sides of the foot of the stump. A fabric circle with numerous through perforated teardrop-shaped holes of the replaceable part 7 is put on the stump of the foot and attached to the permanent part 1 using two straps 8. Plastic fasteners 5 of the permanent part 1 are threaded through the holes 10 of the straps 8 of the replaceable parts 7 and are fixed, and the Velcro petal 9 of the replaceable part 7 is attached to the Velcro petal 6 located on the sole 4 of the permanent part 1. Irrigation of the wound with an antiseptic solution is carried out through numerous through perforations 11 having a teardrop shape.

The fixator of the bandage on the stump of the foot will find wide application in the surgical departments of medical institutions.

Clinical example.

Patient A., 62 years old, was treated in the surgical department of the Ulyanovsk Regional Clinical Hospital on a vascular bed from 01/20/21 to 02/12/21. The patient was admitted in a planned manner.
