WO2020009561A1 - Wound protection device - Google Patents

Abstract

The invention relates to a wound protection device for patients with difficult-to-heal chronic ulcers on lower limbs. The device is in the form of a circular or oval cover having on the top part a domed mesh with multiple holes to allow oxygen to penetrate. The bottom end of the device has an edge with a slight anatomical curve to allow it to sit better on the area of skin where the ulcer is located and to prevent the pressure from causing discomfort. The edge is fitted to a bottom securing element that keeps the device fixed, covering the lesions, supported by an elastic bandage.

2. The present invention relates to the medical field, specifically to the area where ulcers and chronic wounds of lower limbs are treated,

3. The history that is known in practice, currently, to treat chronic ulcers of the lower limbs, chronic infected wounds of difficult scarring or any other etiology, are treated with medications and with the traditional healing technique, based on washing of the diseased area with soap and water, local antiseptics and application of ointments or ointments, healing stimulants and the wound is covered with gauze and elastic bandage and its resolution is verified after several months and some take several years. fhttss: //medlineplus.aov/¾panish/encv/Datientinstructions/000744 htmt

There are also several specialized methods for the treatment of these injuries, among which we can mention:

It is an aerosol that contains small molecules of hemoglobin purified with oxygen since it is known, the main obstacle for a wound to heal is that the cells responsible for repair have little oxygen, the primary lesion prevents the supply of oxygen from within Like the outside, the reason is because the wounds are covered by a thin layer of fluid called exudate that prevents oxygen from spreading properly in the tissues and for that reason the wound cannot heal. There is a need for an external mechanism of action that provides sufficient oxygen to the bottom of the wound to heal properly in the shortest possible time.

Detailed description

4. The wound protection device referred to in the present invention (3) is a cover-shaped piece (1), of different dimensions (4-5 and 11) and circular or elliptical (4-5) , has, at its upper end, a vaulted mesh with multiple small holes so as to allow oxygen to enter the interior of the device {1), at the lower end and external face of the device, it has a flange (1), © I which serves to adjust the bra (2-3), which is responsible for fixing e! device to the place where the ulceration is supported by an elastic bandage (6-7), in this same lower end presents two modalities: The first is the fact of presenting a slight anatomical curvature at the edge of its base that serves to accommodate At the surface where the ulceration or wound is found (3), the other modality is based on the fact that any circumference of the lower end, on the surface of the device, the edge is rounded to attenuate the discomfort caused by the pressure of the device in the area of application, The device is placed covering the ulcerations or wounds instead of covered with gauze, so that the tissues responsible for the healing process have a good supply of oxygen and the formation of new tissue is done more quickly so that the healing time is shortened. In some areas of the legs, there is difficulty in supporting the device, these are the shin or anterior aspect of the leg or also in the ulcerations that are located in the internal or external margins of the leg, invading the shin, for these zones have been devised devices that fit through a curvature at one of the ends of the base of the device (10), or at the center of the base, with an angle that conforms to the shape of the shin (8- 9), Likewise, in cases where patients present ulcerations of larger dimensions on the lateral sides of the leg, a device was considered for these cases (11), and based on the same principles of healing through nourishing The tissues with oxygenation. The state of the art closest to the present invention is precisely the cure through the hyperbaric chamber, also known as hyperbaric oxygen therapy (OHB), referring to using oxygen as the principal! contributing element in the healing of ulcers, highlighting the benefits of the device with respect to the hyperbaric chamber;

 . Jan! inside the device there is continuous flow of oxygen at ambient pressure

 . The wounds, due to the fact that they are covered with the device instead of gauze, are exposed to the action of oxygen, this increases the formation of blood vessels and these at the same time increase the production of new tissue,

 . Healing times are reduced with the device, rather than with the hyperbaric chamber.

 . The risks are not run by prolonged exposure to oxygen at ambient pressure !, such as those that run with prolonged exposure in the hyperbaric chamber.

 . The laboratory studies that are required with the device are routine cough, at a lower cost than those required with the use of the hyperbaric chamber.

 . Device costs, healing and medical expenses are lower than with hyperbaric oxygen.

. Patients who use the protective device can perform their daily work and wander comfortably.

Therefore, it is intended to protect the invention, by means of the present patent application, since it is a device that oxygenates the wounds to accelerate the healing and protect them from environmental contamination or any other damage caused by goipe or rubbing the clothes to the granulation tissue, same that can affect e! Healing course.

 The parts and characteristic details of this device are clearly shown in the following description and accompanying drawings.

 To complement this description and in order to help a better understanding of the characteristics of! In the present invention, the accompanying description is attached as an integral part thereof, the corresponding drawings are illustrative and not limiting.
