MEDICAL DEVICE FOR POSTOPERATIVE COMPRESSION FOLLOWING BREAST RECONSTRUCTION SURGERY

Abstract

A device for postoperative compression of breast skin following breast reconstruction surgery includes a female garment that supports the breast, and wherein each cup of the garment contains inflatable modules with defined pressure gradients that generate different compressive orthogonal vectors on the four quadrants of the breast, leaving the areola-nipple complex free. The inflatable tubular modules have a shape resembling a truncated cone with variable thickness that is minimum in the area closest to the areola-nipple complex, and maximum in the area furthest away from the areola-nipple complex. The inflatable modules can be inflated separately. The device is made up of non-elastic tissue preventing the cups from moving away from breast skin when air chambers are inflated, and includes two non-elastic tissue straps that cross on the spine and close on the front. In the two sub-axillary areas, a Velcro clasp allows operation even when postoperative drainage is in place.

Claims

1. A medical device for the postoperative compression of the skin after breast reconstruction, comprising a female breast support garment, wherein each cup of the garment comprises inflatable modules that, according to defined, pressurized gradients, achieve orthogonal, compressive and different vectors on the four quadrants of the breast, leaving empty the areolar nipple complex.

2. The medical device as in claim 1, whose inflatable tubular modules have, together, a defined shape similar to a trunked cone with variable thickness.

3. The medical device as claimed in claim 1, whose inflatable tubular modules have a minimum thickness (equal to zero) at the nearest part of the areolar nipple complex and maximum at the far end of the areolar nipple complex.

4. The medical device as claimed in claim 1, wherein the inflatable modules are 2 or multiple of 2 and are inflatable separately through the valves.

5. The medical device as claimed in claim 1, wherein it is constituted by inelastic material which has antagonistic function from the removal from the skin of the cups, exerted by inflating the air chambers.

6. The medical device as claimed in claim 1, comprising two inelastic straps that intersect on the back and then close like a waistband in the front.

7. The medical device as claimed in claim 1, wherein there is a closure with velcro in the two sub underarm parts so as to allow insertion of the invention even after operative drainage.

Description

SCOPE

[0020] The main purpose of this invention is, therefore, to solve the technical issues underscored by eliminating the inconveniences of currently available medical devices.

[0021] In fact, the purpose of this invention is to provide compressive and variable orthogonal vectors along the four quadrants of the breast, leaving the central area that corresponds to the areola-nipple complex free. This bra has minimally projecting cups, which internally contain, in the area that interfaces with the skin of the operated breast, several air chambers designed to be inflated with precise mmHg values in order to exert adjustable orthogonal compression on breast skin.

[0022] This device ensures obliteration of dead spaces inside the breast chamber between the various implanted materials and vital tissues.

[0023] Obliteration of dead spaces diminishes the risk of serum build-up, favouring excellent postoperative recovery.

[0024] The invention presents as a bra with two non-preformed cups that are totally closed for 360° without a cleavage between the breasts, and which contain modules that can be inflated according to defined pressure gradients. It is made of non-elastic tissue particularly in the anterior area under the breast groove, and in the subaxillary and posterior area. It also includes two straps that cross at the back and close like a belt on the front.

[0025] The different pressure gradients are created by introducing various quantities of air, and also by the shape of the inflatable modules. A sagittal section (FIG. 9-10-11) reveals that they are tapered near the areola-nipple complex and are broader towards the chest. Hence lesser pressure can be exerted on the area adjacent to the areola-nipple complex, with enhanced pressure on peripheral breast skin.

[0026] The non-elastic tissue prevents the cups from moving away from breast skin when the air chambers are inflated. Hence it ensures that the cups adhere to the breast, allowing air chamber expansion to perform the established axial compression on the breast skin with which it interfaces.

[0027] The above straps are made of non-elastic tissue (FIG. 1-2-3-4-5-6-7-8). A Velcro clasp in the subaxillary area allows the bra to be used even with drainage tubes (FIG. 3). The overall item is a band that allows thoracic expansion for breathing but which, at the same time, maintains compression on breast quadrants.

[0028] The hollow part of every cup that is in contact with the skin has air chambers in a number ranging from one to a multiple of one, placed in a configuration to spare the areola-nipple complex from pressure, and to involve it when clinically required (e.g., mastopexy or quadrantectomy) (FIG. 1-2).

[0029] Air chamber pressure values are defined by the surgeon, depending on the need for compression, and are applied on the various quadrants of the breast, depending on clinical needs, by means of air injected through a manual pump that, along with the pressure gauge, is fitted, from time to time, to the various non-allergic plastic valves in the various quadrants of the breast (FIG. 1-2-3).

[0030] As with breast skin, when operated to remove lymph nodes, the armpit too could need compression designed to obliterate empty spaces by means of bringing internal tissues together. The invention, second element of the system, is shaped according to the complex anatomy of shoulder and armpit.

[0031] It is made up of an element, a broad and fitting shoulder strap (FIG. 4-5-6), that is connected through an extension of non-elastic tissue towards the armpit, to the underarm that internally contains, in contact with the skin, an inflatable air chamber that exerts an orthogonal pressure gradient on the axillary cavity. This element can be connected to the compressive bra by means of LYCRA Fabric® or VELCRO® to prevent it from slipping laterally.
