A medical suction pump has a pump housing, a pump assembly arranged in the pump housing and serving to generate an underpressure, and a device for sound damping. The device for sound damping has at least two elastic bearings for elastically supporting the pump assembly relative to the pump housing, wherein the bearings are arranged spaced apart from each other. By virtue of the flexible support, the suction pump permits optimal sound damping.

An intrapleural pressure regulating device that regulates the pressure in the intrapleural cavity and an operating method therefor are provided. The intrapleural pressure regulating device provides for removal of the foreign substances in the alveolar system and for supporting or replacing the functions of lungs and heart. With the intrapleural pressure regulating device, developed are a device regulating the pressure in the intrapleural cavity by pumping a fluid into the intrapleural cavity and withdrawing it from the intrapleural cavity, and an operating method for variable regulation of the pressure in the intrapleural cavity with said device.

A needle assembly includes an outer cannula having a distal end portion, the distal end portion comprising a sharp bevel facilitating insertion of the needle assembly into a subject. The needle assembly further includes an inner cannula slidably disposed coaxially in the lumen of the outer cannula and movable between an extended position and a retracted position, the inner cannula having a blunt distal end portion extending beyond the sharp bevel of the outer cannula whenever the inner cannula is in the extended position. The needle assembly further includes a bias coupled to the inner cannula in a manner favoring automatic positioning of the inner cannula at the extended position. The needle assembly includes a valve located in fluid communication with the lumen of the inner cannula to allow fluid to exit the subject through the inner cannula, and to prevent ingress of fluid into the subject.
