Patent
Lohmann and Rauscher GmbH | Date: 2015-04-10

Postpartum uterine atony, with life-threatening bleeding, and infections of the endometrium following abortion or birth, can be treated using vacuum therapy. There are no existing drainage systems or vacuum pumps that are suitable for intrauterine therapy. As yet, no intrauterine treatment applications of vacuum therapy have been described. The invention relates to a drainage system and electronic vacuum pump which can be used for intrauterine therapy. An open-pored fluid collection body (1) with a tube-shaped fluid communication element (2) is connected fluid-conductively to an electric vacuum pump (4) via a secretion collection tank (3). For transvaginal placement, the fluid collection body (1) is equipped with a cylindrical cavity (1a) in which a guide rod (5) is inserted, on which guide rod a pusher sleeve (6) can be pushed forward. After placement in the uterus, a vacuum is applied to the drainage system with a contraction pattern similar to labour contractions or postpartum contractions. In the case of a postpartum atony of the uterus, the invention should bring the uterus to contract using the intrauterine vacuum, by imitating and initiating a contraction on the part of the uterus, and thus induce the necessary haemostasis. In the case of infection of the endometrium, the therapy serves for wound healing.

A wound care device having a covering device fixable to the skin surrounding a wound and used for producing a closed wound space containing the wound. At least sections of the covering device are water vapor-permeable. The covering device preferably comprises a tubular film and a suction port across which a negative pressure can be generated in the wound space. The tubular film preferably has an opening with an opening length of at least 80 cm and more preferably of at least 130 cm.

The invention relates to a vacuum sponge unit (2) for use in human or animal bodies, comprising a fluid collecting member (10), in particular a sponge unit, and a fluid communication member (20), in particular a drainage tube, which is disposed at least partially in the fluid collecting member (10) and is connected in fluidic communication to the fluid collecting member (10). In order to improve known devises, the inventions proposed developing the vacuum sponge unit (2) such that the fluid collecting member (10) has a channel (11) for guiding a guide member (3), in particular a guide wire, and/or a delivery member (4), in particular a probe unit and/or an endoscope, through the fluid collecting member (10).

The invention relates to a catheter, in particular a balloon catheter, having a fluid-carrying element, such as a drainage tube, with an inner lumen for carrying away body fluid, and having an expansion element, such as a balloon of variable cross section, for fixing the catheter in a body cavity. The fluid-carrying element has a wall portion of an open-pore material, which is in fluidic communication with the inner lumen and through which the body fluid can be aspirated into the inner lumen by applying a negative pressure to a proximal end of the fluid-carrying element. The invention furthermore relates to a catheter system having a catheter of the invention and to a vacuum-generating system connected to the catheter.
