Description

Изобретение относитс  к медицине, а именно к средствам индивидуальной защиты.This invention relates to medicine, in particular to personal protective equipment.

Известна хирургическа  лицева  маска, содержаща  элемент из фильтрующего материала , имеющий верхнюю и нижнюю части, средства креплени  маски вокруг рта и носа хирурга 1.A surgical face mask is known, comprising an element of filter material having upper and lower parts, means for fastening the mask around the mouth and the nose of the surgeon 1.

Однако при пользовании этой маской происходит запотевание очков хирурга.However, when using this mask, the surgeon's glasses fog up.

Цель изобретени  - предотвращение запотевани  очков хирурга.The purpose of the invention is to prevent the surgeon's glasses from fogging.

Поставленна  цель достигаетс  тем, что маска снабжена полосой из воздухопроницаемого материала, расположенной вдоль одной из поперечных сторон указанного элемента, причем на полосе выполнены щели, образующие клапаны. При этом щели могут и.меть дугообразную или V-образную формы, и образовывать треугльники, вершины которых направлены к противополжной поперечной стороне .The goal is achieved by the fact that the mask is provided with a strip of air-permeable material located along one of the transverse sides of the specified element, with slits forming valves on the strip. In this case, the slits can also be arcuate or V-shaped, and form triangles, the vertices of which are directed to the opposite transverse side.

Кроме того, щели могут образовывать пр моугольные клапаны или клапаны, имеющие три стороны, причем одна из них расположена параллельно поперечной стороне маски, а две другие стороны образуют с указанной стороной углы 90-135°.In addition, the slits can form rectangular valves or valves that have three sides, one of which is parallel to the transverse side of the mask, and the other two sides form angles of 90-135 ° with the specified side.

На фиг. 1 изображена хирургичес ка  лицева  маска на лице хирурга, общий вид; на фиг 2 -то же, в развернутом виде, вид снаружи- на фиг. 3 -то же, внутренн   сторона, на фиг 4 -разрез А -А фиг. 2; на фиг. 5 - маска на лице хирурга, продольный разрез; на фиг. 6 - полоса из воздухонепроцинаемого материала с V-образными клапанами; на фиг. 7 - то же, с пр моугольными клапанами; на фиг. 8-го же, с трапециевидными клапанами.FIG. 1 shows a surgical face mask on the surgeon's face, general view; FIG. 2 is the same, in expanded form, as shown in FIG. 3 is the same, the inner side, in FIG. 4, a section A-A of FIG. 2; in fig. 5 - mask on the face of the surgeon, a longitudinal section; in fig. 6 - strip of air-proof material with V-shaped valves; in fig. 7 - the same, with rectangular valves; in fig. 8th, with trapezoid valves.

Хирургическа  лицева  маска содержит элемент 1 из фильтрующего материала, полосу 2 из воздухонепроницаемого материала, средства креплени  маски вокруг рта и носа в виде лент 3, и носовой зажим 4. Полоса 2 из воздухонепроницаемого материала расположена вдоль одной из поперечных сторон элемента 1 и на ней выполнены щели 5, образующие клапаны. Щели могут иметь дугообразную (фиг. 2) или V-образную формы (фиг. 6). В этом случае щели образуют трегуольники, верщины к оторых направлены к нротивополжной нижней поперечной стороне маски. Кроме того, .щели могут образовывать нр моугольные клапань (фиг. 7) или клапаны, имеющие три стороны, причем одна из них расположена параллельно поперечной стороне маски, а две другие стороны образуют с указанной стороной углы 90- 135°.The surgical face mask comprises a filtering element 1, a strip 2 of an airtight material, means for fastening the mask around the mouth and nose in the form of tapes 3, and a nose clip 4. The strip 2 of an airtight material is located along one of the transverse sides of the element 1 and is made on it slit 5 forming valves. The slits can be arcuate (Fig. 2) or V-shaped (Fig. 6). In this case, the slots form tregolniki, the vertices towards which are directed to the opposite lower transverse side of the mask. In addition, the slits can form either a nodal valve (Fig. 7) or valves having three sides, one of which is parallel to the transverse side of the mask, and the other two sides form angles of 90-135 with the specified side.

При пользовании маской основной объем выдыхаемого теплого воздуха проходит через элемент 1, причем полоса 2 преп тствует .поступлению выдыхаемого воздуха к глазам хирурга, пропуска  его только через щели 5, образующие клапаны и направл ющие потоки воздуха в противоположную от глаз сторону. Тем самым предотвращаетс  запотевание очков .When using a mask, the main volume of exhaled warm air passes through element 1, and strip 2 prevents breath from reaching the surgeon’s eyes, passing it only through slots 5 forming valves and directing air flow to the opposite side. This prevents the glasses from misting up.
