Abstract: A milk suction device consisting of a funnel and a piston pump connected thereto which can be operated easily as a hand-operated pump or as a motor driven pump. A hollow piston rod is constructed as an outwardly guided aeration duct and has a return valve as its opening located in the suction space of a cylinder of the pump, which return valve is closed during the suction stroke of the piston pump and is constructed as an aeration valve. A ventilation valve is arranged in a front face of the pump cylinder opposite the piston rod and in order to connect a motor driven pump, it is only necessary to slide its tube onto the free end of the piston rod.

Abstract: A device for applying tension around an object such as a person's arm and leg comprises a tensioning member which has a first end portion which is connected to a rear end of a hollow basic member housing and includes a portion adapted to form an object encircling loop for engagement, for example around a person's arm and has a second opposite free end portion. The hollow basic member has a rear end wall with an entrance opening and a front end wall with an exit opening to facilitate passage of the free end portion of the tensioning member into the entrance opening through the hollow member and out the exit opening. The interior of the basic member includes a backup portion which has a backup surface over which the free end portion of the tensioning member is passed.
