The invention relates to a hemostasis bag for the gynaecology and obstetrics. The hemostasis bag comprises a handle, an air inflation tube and an airbag, one end of the air inflation tube is connectedwith the handle, and one end of the air inflation tube is connected with an air inflation device; the other end of the air inflation tube is communicated with the airbag, a hemostasis bag body wrapsthe outer side of the airbag, and the airbag and the hemostasis bag body are arc; hemostasis medicine cotton wraps the outer side of the hemostasis bag body, and multiple medicine outlets are evenly formed in the hemostasis bag body. According to the hemostasis bag, the air bag is inflated through the air inflation device, the hemostasis bag body is expanded, even compression hemostasis can be conducted, hemostasis medicine liquid is injected to a medicine application tube through an injector and flows out from the medicine outlets of the hemostasis bag body, and hemostasis treatment is achieved; a pressure sensor between the airbag and the hemostasis bag body can detect the contact pressure between the hemostasis bag body and the vaginal wall and is used for controlling starting and closing of a micro electric air inflation pump, waste liquid can be discharged through a liquid discharge pipe, environment sanitation can be guaranteed, and the burden of medical personnel is reduced.

The invention discloses an airbag running weight device allowing end face assisted load adjustment. The airbag running weight device a rubber roller and tube shafts disposed at two ends of the rubber roller. The outer surface of the rubber roller is provided with cylindrical non-slip teeth; an airbag is disposed within the rubber roller; two end faces of the airbag are provided with bristles by embedding; the airbag is hermetically integrated to the tube shafts through two end plates on two sides; two ends of the tube shafts are connected with the end plates through bearings; a bearing block bore of each end plate and a bearing outside thereof are in clearance fit; when the airbag is expanded with compressed air, the tube shafts drive the bearings to move in the bearing blocks of the end plates, and the end plates and the rubber roller are fixed to form a roller assembly flexibly rotatable; one end of each tube shaft is provided with a nozzle communicated with the airbag. By make ingenious use of the pneumatic expansion of the airbag to adjust contact pressure of the bristles and the inner surfaces of the end plates, a running weight is adjusted; end face contact allows convenience for flexible adjustment of the load; the structure is simple and ingenious, the diversified weight running training needs are met, and the application prospect is promising.

)Disclosed is a method for treating the interiors of kegs (3), each of which is equipped with at least one keg fitting (2), using at least one treatment head (4, 4a) which has a mating- and contact pressure element (23) on a treatment head housing (5), for sealingly mating with the keg fitting (2) during the treatment. The keg (3) that is to be treated is pressed onto the housing, by a feed and mating stroke, with the keg fitting of said keg lying sealingly against the mating and contact pressure element (23), and then the keg fitting (2) is opened by a relative movement between said fitting (2) and a lifter (12) of the treatment head (4, 4a), thereby connecting at least one flow path (10, 21) formed in the treatment head (4, 4a) to the interior of the keg (3).
