Description

BIRTHING DEVICE FOR ASSISTING CHILDBIRTH
The present invention relates to a birthing device for assisting childbirth. More particularly, the present invention relates to a birthing device for preventing obstructed labour during childbirth.
Every year, approximately 28 million women (20% of all women who give birth) experience obstructed labour during childbirth. Obstructed labour occurs when despite strong uterine contractions, the presenting part of the foetus cannot progress through the birth canal. The most frequent cause of obstructed labour is cephalo-pelvic disproportion (a mismatch between the foetal head and the mother’s pelvic brim). Other causes of obstructed labour include malpresentation or malposition of the foetus.
Once obstructed labour has occurred, it can only be alleviated by means of an operative delivery, either by a caesarean section or by other instrumental delivery (forceps, vacuum extraction or symphysiotomy). Maternal complications of obstructed labour include intrauterine infections following prolonged rupture of membranes, trauma to the bladder and/or rectum due to pressure from the foetal head or damage during delivery, and a ruptured uterus with consequent haemorrhage, shock or even death. In the infant, neglected obstructed labour may result in asphyxia leading to stillbirth, brain damage or neonatal death.
Accordingly, it is an object of the present invention to provide a birthing device for preventing obstructed labour during childbirth in order to circumvent the above-mentioned maternal and infant complications commonly associated with obstructed labour.
According to a first aspect of the invention, there is provided a birthing device for preventing obstructed labour during childbirth comprising: - a sleeve having a first opening at one end, and a second opening at the other end; - the first opening having a diameter smaller than a baby’s head; - the second opening having a diameter larger than a baby’s head; - a first loop member attached to the sleeve proximate to the first opening, or preferably attached to the end of the first opening; and optionally - a second loop member attached to the sleeve between the first loop member and the second opening.
The first opening may have a diameter of less than 12 cm, or less than 11 cm, or less than 10 cm, or less than 9 cm, or less than 8 cm.
The second opening may have a diameter of more than 7 cm, or more than 8 cm, or more than 9 cm.
