Description

The inventive glove relates to personal protective equipment of medical personnel and is intended to protect the hands of a surgeon during surgery, for example during lung surgery with a surgical tool.

Known protective glove containing an outer shell and protective elements embedded in the outer shell (Patent RU 2425611, 06/11/2010 [1]). The analogue [1] is designed to protect hands from cuts and punctures in an industrial environment.

The closest analogue to the claimed object is a medical glove containing a shell of elastic material with an inlet and five protrusions of a tubular shape with blind rounded ends for nesting fingers: large, index, middle, ring and little fingers (Medical gloves. / Gms.su [2 ]). The analogue [2] was chosen by us as a prototype.

Reliable mechanical contact is not always ensured between the surface of the glove [2] and a surgical instrument, such as a scalpel handle, for example, with a wet surface of the scalpel handle, which can lead to slipping of the glove and the surgeon's hand relative to the instrument and unnecessary injury to the patient.

The aim of this work is to increase the reliability of mechanical contact between the surface of the medical glove and the instrument through the use of an electrostatic magnet.

The technical result of the utility model is expressed in expanding the arsenal of personal protective equipment for medical personnel. It is achieved by the fact that in a medical glove containing a sheath of elastic material with an inlet and five protrusions of a tubular shape with blind rounded ends for nesting fingers: thumb, index, middle, ring and little fingers, on the outer surface of the tubular protrusions of the thumb and forefinger, beneath their cushion, an electret with an electric potential of 15-20 kV, made of an elastic material in the form of an ellipse with a thickness of 1.0-2.0 mm, is fixed, and the plane of polarization of electric charges against the opposite sign (-), (+) in the electret pass parallel to its plane.

Further description is accompanied by drawings and explanations to them. In FIG. 1 shows a general view of a medical glove (top view), FIG. 2 is a section AA of FIG. 1, and in FIG. 3 - the principle of operation of the proposed medical gloves.

The proposed medical glove 1 has a sheath made of an elastic material, for example, latex, with an inlet 2 for introducing a doctor’s hand and five protrusions 3 _a , 3 _b , 3 _s , 3 _d , 3 _{e of a} tubular shape with blind rounded ends for fingers: large , index, middle, nameless and little finger. On the outer surface of the tubular protrusions 3 _a , 3 _{b of the} thumb and forefinger, under their cushion, an electret is fixed, respectively 4 _a and 4 _b with an electric potential of 15-20 kV, made of an elastic material, such as Teflon, in the form of an ellipse with a thickness of 1, 0-2.0 mm, and the plane of polarization of electric charges of the opposite sign (-), (+) in the electret pass parallel to its plane (Fig. 2).

Electrets are electrical analogues of magnets. They create a constant electric field in the surrounding space and have a long-lasting effect (up to many years) (Physical Encyclopedic Dictionary. - M.: Sov. Encyclopedia, 1983. - P. 862).

When gripping and holding a tool, for example, a scalpel handle 5, with the hand of a surgeon wearing a glove 1, the main work is performed by the big G and index L fingers located in the tubular protrusions 3 _a and 3 _b , on which electrets are attached, respectively 4 _a and 4 _b (Fig. 3).

Under the influence of the electric field of the electret 15-20 kV in the material of the handle 5 of the tool adjacent to the electret, an electric charge of the opposite sign is induced. So, if the charge of the electret has a potential of +15 kV, a charge of -15 kV is induced in the material of the handle 5. As a result of this, under the influence of electrostatic force, the electret mounted on the tubular protrusion of the glove “sticks” to the handle 5 of the tool, which completely eliminates the slipping of the glove relative to the tool.

Claims (1)

Medical glove, containing a sheath of elastic material with an inlet and five protrusions of a tubular shape with blind rounded ends for nesting fingers: thumb, forefinger, middle, ring and little fingers, characterized in that on the outer surface of the tubular protrusions of the thumb and forefinger, under them cushion, fixed electret with an electric potential of 15-20 kV, made of an elastic material in the form of an ellipse with a thickness of 1.0-2.0 mm, and the plane of polarization of electric charges is opposite the false sign (-), (+) in the electret pass parallel to its plane.
