Aspirator bottle for use in the draining of wounds

摘要

The aspirator bottle (1) has an aspirator vessel (11) with a vacuum display arrangement (15). In a transparent attachment (11a) provided with a scale and moulded onto the lid of the aspirator vessel (11), a spring (25) is inserted whose end facing towards the inside of the aspirator vessel bears on a support surface (11b). A measurement and display member (27) has a bellows (27a) which is arranged in the attachment (11a) and comprises folds, the inside of the bellows at the end facing towards the inside of the aspirator vessel being closed off in a leakproof manner by a display part (27b), which is acted upon by a pressure force from the spring (25). At the other end, the bellows (27a) is connected to a collar (27c) which is clamped securely to a clamping sleeve (29) on the attachment (11a), the inside of the bellows (27a) at this end being connected in fluid terms to the environment. When the partial vacuum prevailing in the inside of the aspirator vessel (11) decreases during use of the aspirator bottle (1), the spring (25) pushes the display part (27b) away from the inside of the aspirator vessel, thus affording a relatively accurate and easily readable display of the partial vacuum.
