The suction bottle (1) for wound drainage has as a pressure indicator a transparent cylinder (6), which is provided with a scale (9) and with a piston (10). The one cylinder space is connected to the inside of the suction bottle (1). The other cylinder space is sealed by means of a cover (8) and is provided with a gauged gas volume. The piston consists of a rigid core (11) with a jacket (12) of silicone rubber. The inner wall of the cylinder is silicone-treated. A pressure indicator of this type is leakproof and accurate and, moreover, inexpensive. <IMAGE> |
