Delivery Vacuum Extraction Cups

Medical Silicones Soft Vacuum Extraction Cups and Hand Pumps

Salient Features:

Medical Grade Silicone Rubber ensures absolute biocompatibility and high durability

Available in two sizes (50mm - Navy Blue & 60mm - Pink)

Smooth External surface with a small longitudinal ridge to observe any rotation

Inside the cup is lined with smooth projections, which enable the air between the cup and the child's head and ensure that the cup sucks fairmly on child's head

The soft suction cup deforms, thereby ensuring optimal adhesion and minimizing trauma to the fetal scalp

Innovative Design of Hand Operated Vacuum Pump:

The moden Custom-made medisil vacuum pump is very handy and easily carriable

The desired level of vacuum can be acheived quickly and the pressure is maintained

German make calibrated guage shows accurate pressure

Easy vacuum release system and free from the obsolete bottle techniques

Highly durable and maintenance free

Designed for absolute silent operation which provides no distraction to the patient

Sterlization:

Before use, the cup and the tubing should be washed seperately using soap and water, after washing, the cup and the tubing should be fitted together and sterlization by autoclaving method at 134 deg C for 3 minutes

Techniques for using silicon Cup:

Silicone cups are particularly useful when the exhausted mother has endured the tedium of a long labor, and requires assistance during the second state. When the fatal head is on the perineum, well flexed and occipito-interior, the silicone cup device may expedite delivery (Fig1) the device is unsuitable for medicavity deliverys and abnormal positions, particularly in the presence of caput and moulding.

For the Silicone cup delivery of a baby well below spines with its head flexed in the occipito-anterior position, lithotomy position is not mandatory, given that down-ward traction required for midcavity deliveries may not be needed. Delivery may be undertaken in the dorsal, left lateral or even squatting positions.

Application of Silicone Cup:

After the application of antiseptic obsterical cream, the cup is squeezed at its widest point to facilitate gentle introduction through the vulva. The cup must sit easily and comfortably between the fetal head and perineum, the moved to ensure its correct position over the posterior fontanelle with 30mm between the cup margin and the bregma. The index finger is passed around the rim to ensure no maternal tissue is pinched between the fetal scalp and the cup, and a vacuum of -20Kpa is induced. The cup tends to flatten against the fetal scalp. Position and application are rechecked. A full vacuum of -80Kpa is obtained, and traction commenced at the next uterine contraction (Fig2). Since a chignon does not form in soft cups, there is no 2minute waiting period mandatory as in metal cups.

Traction:

Traction in synchronous with uterine contractions, the right hand supplying firm, gentl tension, and the finger of the left hand on the scalp/rim margin to ensure the head itself descends, and not merely the scalp. Three gentle pulls should be sufficient to delivery most babies especially, if the cup is applied correctly and the traction is in the direction of maternal pelvic axis.

An audible hiss suggests traction is too severe and should be momentarily relaxed to prevent cup seperation. If this occurs the cup may be reapplied not more than twice, otherwise the procedure must be abandoned. Generally routine episiotomies are superfluous and only cut if obstetrically indicated, for example fetal distress. After delivery of the head, the cup is released and the rest of an infent delivered in normal way. Traction is not normally applied between contractions, but it may sometimes be helpful to hold the head in place between contraction so it does not move back up the birth canal.

Fetal: Fetal Distress in second State

Meternal: delay in second stage. Maternal conditins requiring a short second state

Pressure Recommended: -80KPA for 50mm cup and -60 to -80 KPA for 60mm cup
