Technical Field
The present invention relates to an assembly comprising a suction device which can be placed over a wound and/or incision and a method of installing the same on a patient in need of wound hemostasis and healing.
The present invention relates to the technical field of medical accessories, aimed at disinfecting and/or stopping bleeding of incisions and/or wounds in surgical and/or emergency operations, and more particularly to the technical field of surgical fields.
Background
The surgical procedure can be performed using a number of existing surgical fields. For example, during a surgical procedure, a surgical field equipped with an incision viewing window through which a surgical procedure can be performed is often used. These surgical fields are placed on the patient's skin in order to isolate and protect the incision tract from contamination. They form an effective barrier between the body of the patient and the operating room environment.
These surgical fields are not completely effective in disinfecting and/or stopping bleeding of the surgical site. In fact, once the skin is incised, incision secretions (haemorrhages and/or body secretions) occur, which may damage the incision edges and cause infections of the walls and/or the surgical site, in particular nosocomial infections. Severe blood loss may occur and anemia may result from the blood loss. In addition, these secretions cover certain portions of the surgical site, thereby preventing the surgical procedure from being performed successfully. It is therefore necessary to empty the incision secretions, usually using absorbent pads which, after being completely saturated, need to be replaced regularly. Absorption of exudate by the absorbent pad requires additional manipulation around the surgical site, which may hinder the surgeon performing the surgical procedure. These absorbent pads are then discarded and the blood contained therein cannot be recovered.
The sterile absorbent pad attached to the end of the surgical sheet described in patent document US 4.089.331(KENDALL & CO) does not allow for efficient absorption of the incision secretions. In fact, when the absorbent pad is completely saturated, it is no longer possible to absorb the secretions, so that it is necessary to continue to use other absorbent pads, again requiring additional operations around the operative site.
For wounds, WO 2003/018098(KCI LICENSING INC) discloses a system for accelerating the healing of difficult-to-heal tissue. The system includes a porous tampon introduced into the wound, and an airtight dressing secured to the tampon to effect an airtight closure of the wound. The proximal end of the tubing is connected to the dressing and the distal end of the tubing may be connected to a source of negative pressure, such as an electrically powered pump. The retriever, which is mounted on the pipe, can store the exudate sucked from the wound during the application of negative pressure. The system, while effective, is complex, neither protects the wound from possible nosocomial infections, nor is it prophylactic.
The patent document WO 2009/080922(TOUATI) proposes to overcome some of the above-mentioned disadvantages. It describes a suction device which can be placed at an incision and/or wound of a patient and used for disinfecting a surgical site. The device comprises an operation field, and is composed of an outer layer and an inner layer, wherein the outer layer comprises an upper surface and a lower surface, and the inner layer also comprises an upper surface and a lower surface. The inner lower surface is adapted to contact the wound and/or incision. Despite the improvements made to the prior art, the suction performed by such devices is extremely limited and in any case does not allow autotransfusion of the patient during the operation.
The patent document US2005/0028828(HEATON) discloses a suction device that can be placed on a wound and/or incision of a patient. The device comprises a sterile surgical field consisting of an outer layer provided with a suction head and an inner layer intended to come into contact with the wound and/or incision. The inner and outer layers are two separate pieces. The physician first places the inner layer over the wound and/or incision and then covers the inner layer with the attached outer layer. Therefore, a plurality of steps are required to install the suction device, which is not only cumbersome but also time consuming, and thus is not well suited for first aid in practice.
The present invention aims to improve this situation. In particular, the object of the invention is to propose a device which is able to disinfect wounds and/or incision edges more effectively than the prior art.
Another object of the invention is to propose a device that can be used in emergency situations and that allows the reuse of blood lost by the patient in the presence of traumatic wounds.
It is a further object of the invention to provide a device that is easy to use and does not interfere with the physician.
Disclosure of Invention
The solution proposed by the invention consists in an assembly comprising:
-a suction device that can be placed at an incision and/or wound of a patient for disinfecting and/or stopping bleeding of the incision and/or wound, said device comprising a surgical field consisting of:
an outer layer comprising an upper surface and a lower surface,
an inner layer comprising an upper surface and a lower surface, the lower surface for contacting a wound and/or incision.
-a suction member.
The assembly is characterized in that:
the upper surface of the outer layer of the surgical field is impermeable,
the surgical field may wrap around a patient's limb or torso,
-the outer and inner layers of the surgical field are made as one-piece parts, such that the outer and inner layers are wrapped simultaneously when the surgical field is wrapped around a limb or torso of a patient,
a suction zone with a cavity is arranged between the lower surface of the outer layer and the upper surface of the inner layer, the periphery of the suction zone is closed,
-a drainage tube is connected to the suction zone, said drainage tube ending in a connection for connection of a suction member for creating a suction underpressure in the suction zone,
the suction member is a portable or mobile autologous blood recovery system.
By utilizing the device, the operation field can wrap the limbs or the trunk of the patient rapidly under the condition of heavy bleeding. By this design, the suction area and its lumen allow rapid recovery of large volumes of blood which are to be recovered for reuse, particularly in the case of autotransfusion. In addition, the wound and/or incision remains relatively clean and/or dry, thereby stabilizing the overall condition of the patient or injured person.
Other advantageous features of the invention are listed below. Each of these features can be utilized alone or in combination with the other significant features described above, and in cases where necessary, as one or more divisional patent applications:
the inner layer may be formed of a neutral gauze, thereby minimizing interaction with red blood cells,
the suction zone may be constituted by a mesh of perforated ducts,
the suction zone may be constituted by a porous foam,
the suction zone may be constituted by a grid of ducts,
the surgical field may be constituted by separable male and female parts,
the whole or part of the incision viewing window can be moved into the surgical field in order to access the wound and/or the incision.
The invention also relates to a method for mounting an assembly according to the invention, comprising the following steps:
-securing the suction protection device by:
placing the lower surface of the inner layer of the surgical field opposite the incision and/or facing the wound,
wrapping the surgical field around the patient's limb or trunk with the incision and/or wound,
-connecting the suction member to the drainage tube.
