DE2826074A1 - Mattress for pregnant women - has countersunk air chamber shaped by inflation to fit against stomach when lying face downwards - Google Patents

Abstract

The mattress is particularly for expectant mothers, and has a counter-sunk air chamber in the portion against which the stomach bears when lying face downwards. By filling or emptying this chamber (2), it can be shaped to accommodate the stomach, or fully inflated to make the surface of the mattress (1) flat and thus allowing lying on ths side. The design avoids many effects which can harm the mother or the foetus such as restriction of blood and oxygen supplies etc.

11 Lounger cushions for pregnant women "The invention relates to a lounger with a special device for pregnant women. Lounger cushions that take into account the special physiological conditions during pregnancy are not known A disadvantage is that when you lie on your back, and to a lesser extent when you lie on your side, the weight of the fetus, uterine, placenta and amniotic fluid stresses internal organs and vessels of the pregnant woman. Ureters and kidneys affected. This can trigger a number of pathogenetic factors, especially if it persists for a long time: 1.) Load and narrowing of the lumen of the aorta abdominalis 9Q98EJJ / 0278 with simultaneous venous congestion due to vena cava compression impair the blood and oxygen supply to the uterus, placenta and fetus. Lack of oxygen leads to the fetus depending on. Degree and duration to acidosis, edema, hemorrhage, deficiency or Developmental defects, cerebral damage, cell necrosis and increased erythropoiesis. 2,) By, the increased erythropoiesis results from the B4- ^S sirubin increase in the blood of the newborns ρ ine heavy liver load. The "icterus neonatorum" therefore occurs in most newborns. 3,) Oxygen deficiency and increase in CO ^ in the blood can occur after. Maturation of the respiratory center respiratory movements of the Trigger the fetus, which will aspirate the amniotic fluid. Water in bronchial and lung tissues, acidosis, edematous swelling and inadequate materno-fetal supply of surface-active substances, which are a cause the lung tissue to unfold without sticking Can the dyspnea syndrome of the newborn trigger, 4,) When the pregnant woman is supine during the late The kidneys and their vascular system become pregnant (Also. Lymph vessels mechanically affected. On the other hand, they are extremely sensitive and it occurs Bradykinin and histamine release, changes in prostaglandin metabolism, activation of the Eenin-Angiotensin-Mechan'ismus, Increase in blood pressure and protein excretion. 5,) When the adrenal glands react, adrenaline and adrenal cortex hormones are released, thus to further increase in blood pressure and increased blood sugar level, -2- 909851/0278 • t · _ O - · · · iii ■ · m £ * ^ i · κ B ■ · sa ti 3098_§_1 / 0278 6.) When ureter congestion is often increased blood pressure and, | Excretion of protein in the urine observed. / l 7.) Ureter congestion can cause kidney pelvic inflammation can be triggered. yy 8.)

Intrauterine \) Fruit death, maternal and newborn mortality % are high here. Il 1o.) In the presence of a rhesus or other blood intolerance can be a utero-placental infarction.

Through. vena cava compression is provided by the venous Back pressure in the legs causing varices ^,! Edema and deep vein thrombosis promoted. A pulmonary embolism can be a serious complication follow. 13.) The right heart pumps itself with vena cava compression quickly empty and the oxygen content of the maternal and child blood drops. 14.) In addition to the uterus, kidneys and legs, other organs and tissues are affected by the insufficient blood flow. at Organs of the digestive tract can cause mechanical stress and impaired function to irritate the heart through the gastro-axial reflex. 15.) Another cardiac load results from the increased Blood pressure. ' 16.) Heart failure due to high pressure, lack of oxygen and gastrocardiac reflex as well as the reduction of the colloid-osmotic pressure in the blood due to protein loss promote the development of edema. 17.) Elevated blood pressure, protein excretion in the urine and edema are the main symptoms of late gestosis means a serious risk to mother and fetus and often forces premature termination of pregnancy. Frequent supine position of the pregnant woman must be the main factor in causing this disease be seen. The invention is based on the object of creating a cushion for pregnant women that enables them to sleep and rest physiologically. This object is achieved according to the invention in that in 90985 ⁴ i70278 the area of the lying cushion on which the pregnant woman lies with the bulging abdomen in the prone position comes, an air chamber sunk into the lying surface is attached, which can be precisely adjusted by filling or emptying the shape of the belly of the pregnant woman can be adapted and this can be adapted to the prone position as well as if the filling is full the air chamber, which makes the lying surface flat, allows you to lie on your side. In such a prone position, the fetus is neither burdened nor burdened by the weight of the pregnant woman this, as in the supine position of the pregnant woman, together with the uterus, amniotic fluid and placenta inner. Organs and vessels. The pregnant woman can determine the degree of air chamber filling Determine yourself, most expediently by means of an electric air pump, the switch on a cable within easy reach is ready. As a result, the following advantages can be obtained. 1.) Prevented or mitigated-i can be a) in the fetus: development of deficiency, icterus after birth, erythroblasts tose, spasticity and others Diseases caused by the high bilirubin content of the blood, respiratory distress syndrome. b) in pregnant women: late gestosis, placenta infarction, premature placenta dissolution, antibody formation against Phesus - various erythrocytes, that could harm the next child, pelvic inflammation, Leg edema, varices, deep leg vein thrombosis, pulmonary embolism, oxygen deficiency, Heart failure, 2.) The improvement in uterine blood flow leaves one 9 0 9 ^ .5 1/0278 lilt expect faster and easier childbirth. 3.) Many pregnant women find it very comfortable, even during late pregnancy in the prone position to be able to rest or sleep. 4.) A load on the spine in the prone position due to the weight of the fetus, uterus, placenta and amniotic fluid the pregnant woman can avoid by the degree of the air chamber filling. 5.) Due to the adaptability of the air chamber to the shape of the abdomen of the pregnant woman, the cushion of from the point in time at which the pregnant woman's body begins to bulge until shortly before the birth will. 909851/0278 In the following the invention is based on an exemplary embodiment Illustrative drawing explained in more detail. Show it: Fig. I - a perspective view of a mattress support pad for pregnant women Fig. Ii - the object of Fig. I with one of the shape of the air chamber I] Fig. III - the cushion in the plan An air chamber (2) is sunk in the plane of the cushion (1). Will the pregnant woman up lying on the side, it fills the air chamber (2) with air, making the lying surface flat; for the prone position, it can adjust the air chamber (2) by deflating the abdominal bulge, which means neither it affects the fetus, nor does the fetus burden it. 909851/0278
