<p>The filter for use in medicine and in a laboratory, especially for blood analysis and the like, has a plastics housing with a lower section (4) and a cover (6). The exchangeable filter membrane (12) is clamped between the cover and the lower section. The free lower ends (18) of the levers have hook-shaped projections (20) which give a positive fit locking action with the lower section when pressure is applied to the cover. The filter for use in medicine and in a laboratory, especially for blood analysis and the like, has a plastics housing with a lower section (4) and a cover (6). The inflow (8) is at the cover and the outflow (10) is at the lower section. The exchangeable filter membrane (12) is clamped between the cover and the lower section. A lock (14) holds the cover at the lower section in a fluid-tight seal, with spring levers (16) at intervals around the cover circumference, as plastics levers in one piece with the cover. The free lower ends (18) of the levers have hook-shaped projections (20) which give a positive fit locking action with the lower section when pressure is applied to the cover.</p> |
