Description

The invention relates to medicine, namely to plastic surgery, and can be used in the manufacture of compression masks applied to patients in the postoperative period.

A compression cooling face mask is known, made in the form of a wearable device made of elastic material by a person, including a phototherapeutic unit, a docking station and an adjustable length fastening element made of elastic material for fastening to the surface of a person's face. The fastening element is made in the form of a face mask having an outer and inner layer, the inner layer of the mask adjacent to the surface of a person's face is made of a light- and heat-conducting moisture-absorbing mesh elastic material. Between the inner and outer layers of the mask in the projection of the facial part of the skull there are pockets with a slit in the outer layer. The inner wall of the pocket is represented by the inner layer of the mask, and the outer wall is corrugated from a reflective material and connects the inner and outer layers of the mask (according to patent RU 2682473, A61F 7/00, A61H 39/06, published on 19.03.2019).

The disadvantage of the known mask is its limited scope of application, namely after dental surgeries. The use of this mask after plastic surgery on the face is ineffective, since the mask cannot fit tightly to the patient's skin and repeat the contours of each patient's face.

The closest technical solution is a compression mask for postoperative cooling of the soft tissues of the patient's face, characterized by the fact that the mask body with slits for the eyes, mouth and nose of the patient is made 0.5-2.0 mm thick from a biologically compatible and non-toxic polymer material. In this case, the configuration of the mask body is modeled based on the results of a previously performed computer tomography, a 3D photographic image of the soft tissues of the patient's face, as well as on the basis of a model created and manufactured using 3D printing with the boundaries of the postoperative area of the soft tissues of the patient's face. Moreover, it is equipped with means for fastening and fixing it on the head of the operated patient in the form of an elastic fastening strap adjustable in terms of the degree of compression pressure on the surface of the soft tissues of the patient's face, the inner surface of the compression mask body is equipped with a cooling system for the surface of the operated soft tissues of the patient's face, made in the form of vertically arranged serpentine branches of a continuous curved cooling tube with rounded transitions placed and fixed on the inner surface of the compression mask body with no intersection of the serpentine branches and an inlet for feeding and an outlet for a cooling liquid or gaseous component made of a biocompatible and non-toxic polymer tubular material with an outer diameter of 2-3 mm with distances between two adjacent branches of the cooling tube from 5 to 8 mm (according to patent RU 2645646, A61F 7/00, A61H 39/06, published on 26.02.2018).

The disadvantage of the known mask is the complexity and labor intensity of its manufacture. Preliminary modeling of the mask body configuration is required based on the results of a previously performed computer tomography and/or 3D photographic image of the soft tissues of the patient's face. Also, during scanning and manufacture, inaccuracies in the shape of the mask may appear. The mask will not accurately repeat the contour of the patient's face, which means that the pressure from the mask will be distributed unevenly, which will lead to ischemia and the appearance of edema and hematomas.

The technical result of the proposed invention consists in ensuring a tight fit of the mask and its uniform pressure on the entire surface of the lower third of the patient's face and neck.

The specified technical result is achieved by the fact that the postoperative compression mask consists of an inner layer and an outer layer and is distinguished by the fact that the inner layer is made of polymorphus, which in a heated plastic state is applied to the lower third of the patient's face and neck, and the outer layer is a bandage that tightens and fixes the inner layer.

The invention is illustrated by drawings, which depict:

Fig. 1 - application of the inner layer of the mask to the patient's face;

Fig. 2 - application of the outer layer of the mask to the patient's face.

The postoperative compression mask consists of an inner layer 1 and an outer layer 2. The inner layer 1 is a layer of polymorphus - a thermoplastic plastic that initially consists of solid granules that melt at a temperature of about 65°C. The outer layer 2 is a self-fixing bandage.

After the plastic surgery, a compression mask should be applied to the patient's face to reduce swelling and prevent early postoperative complications. The face is first covered with hydrogel or gauze bandages, which reduce pressure and create a moist environment, and are also used to apply medications that enhance healing. Then the polymorphus granules are heated in hot water to form a plastic mass, from which the inner layer of the mask is formed in the shape of the lower third of the patient's face and neck. The inner layer fits tightly to the skin of the face, repeating its contours. Then a bandage is gently fixed over the inner layer, forming the outer layer of the mask. The mask is removed the next day after the surgery during the dressing. The mask can be reused, since postoperative swelling can increase over three days, and then begins to subside. Accordingly, the mask is modeled and restrains swelling according to the individual volume. This is possible due to the fact that the polymorphus material can be heated repeatedly, and it takes the desired shape.

The use of the described mask, due to uniform pressure on the surface of the face, promotes regeneration, accelerates healing and prevents the formation of hematomas, and also removes the ischemia factor in the areas of natural facial curves.

In addition, one of the advantages of the described mask is the ability to make holes in it for drainage.

Thus, the proposed technical solution ensures a tight fit of the mask and its uniform pressure on the surface of the patient's face and thus allows achieving the stated technical result.
