Abstract: An appliance is provided for negative-pressure therapy of wounds on the human or animal body in which, on the one hand, a substance is delivered to a wound bed (W) and, on the other hand, fluids, in particular an exudate and the delivered substance, are aspirated from the wound bed by negative pressure. The appliance has a suction pump housing, with a suction pump arranged therein for aspirating the fluids from the wound bed (W), and a fluid collection container for collecting the aspirated fluids. Moreover, the appliance has a first measuring device and a second measuring device. The first measuring device serves to determine the quantity of the aspirated fluids, and the second measuring device serves to determine the quantity of the substance delivered to the body.

Abstract: A device for aspirating and transferring blood during a surgical operation has a first chamber and a second chamber for collecting and transferring the aspirated blood, and an electronically controlled valve unit for connecting the chambers to a vacuum source. The valve unit establishes this connection alternately between the first chamber and the vacuum source and the second chamber and the vacuum source, such that the first or second chamber connected to the vacuum source can be filled with aspirated blood, and the other, second or first chamber can be emptied at the same time. The valve unit is connected to the first and second chamber and permits a pressure increase in the first or second chamber to be emptied. This device allows blood to be efficiently collected and transferred during operations in a way that is gentle on the blood.

Abstract: Devices and to methods for thoracic drainage for a patient having an air fistula. A vacuum is produced in the pleural cavity of the patient by means of a suction device. In order to adjust the vacuum on the basis of objective criteria, a suitable size measure for the air fistula is determined and the vacuum produced by the suction device is controlled according to said size measure. An adaptive algorithm includes: (a) determining a first value of a size measure for the air fistula; (b) changing the vacuum by a first difference value; (c) determining a second value of the size measure after a first waiting period; (d) changing the vacuum by a second difference value having the opposite sign if the second measure is greater than the first measure; (e) repeating steps (a) to (d) after a second waiting period.

Abstract: A medical suction pump for aspiration of bodily fluid has a suction pump housing, a fluid collection container held releasably on the housing, and at least one filling level sensor. The fluid collection container has a first side wall and at least one further side wall which together delimit at least one interior space for receiving the aspirated fluid. The at least one filling level sensor extends at least approximately parallel to the first side wall over at least a partial area of the fillable height of the interior space. The first side wall is place at least in part, and the cross section of the at least one interior space tapers vertically from the top downwards, at least over a partial area of the fillable height.

Abstract: A thorax drainage device for aspirating fluids from a pleural cavity of a patient using underpressure has a fluid collection container for collecting the aspirated fluids and a drainage tube for connecting the fluid collection container to the pleural cavity of the patient. The fluid collection container is connectable to a vacuum source, in order to generate an underpressure in the fluid collection container. The thorax drainage device has an adjustable mechanism for attenuating pressure differences during the respiration of the patient, this mechanism being adjustable independently of a suction capacity of the vacuum source. This device permits a gradual expansion of the lung without risk of injury and thus prepares the lung for the completion of the drainage.

Abstract: A suction apparatus for aspirating a fluid from a human or animal body by negative pressure comprises a drainage connection for a drainage line in order to remove the fluid from the body. A vacuum source generates a negative pressure at the drainage connection. A fluid connection container collects the sucked-up fluid. The drainage line can be flushed with air by an auxiliary connection and an auxiliary line connected to the latter. In order to reduce the entraining of pathogens, a sterilizing cell is provided. The supplied air is treated in the latter in such a manner that pathogens contained in the air are modified and thereby rendered harmless.

Abstract: A coupling part of a drainage tube unit for aspirating body fluids by a suction pump includes a patient-side drainage attachment, a pump-side drainage orifice for connection to a drainage tube, and a drainage channel connecting the drainage attachment and the drainage orifice to each other. The coupling part also includes a pump-side first service orifice for connection to a service tube, a second service orifice ending in the interior of the coupling part, a service channel connecting these first and second service orifices, and a device which separates the service channel from the drainage channel. The device permits delivery of fluid from the service channel into the drainage channel and prevents delivery of particles and liquid from the drainage channel into the service channel. The device is arranged in the coupling part at a location that allows a flow through the drainage channel from the drainage attachment to the drainage orifice without passage through the device.

Abstract: A swirl pressure nozzle with a nozzle body is proposed, in which an inner area is provided, which has a tapered section with a largest diameter and a smallest diameter. The nozzle has an inlet which leads into the section in an essentially tangential manner, which has a diameter, such that a fluid medium can be guided under pressure through this inlet in an essentially tangential manner into the tapered section of the inner area. The section has an axial length and at its end with the smallest diameter leads into an outlet of the nozzle, which has the same diameter as well as a length. The different parameters are in a ratio to each other, that lies in the following ranges: Dp/Do in the range from 0.42 to 1.56; Ds/Do in the range from 3 to 8; the angle of opening (alpha) of the tapered section greater than 60°; Lo/Do in the range from 0.2 to 1.5.
