Abstract

The invention discloses a fixing device for a membrane type oxygenator. The fixing device comprises a shell, a snapping buckle member and a driving member, wherein the shell has a first accommodatingspace, a second accommodating space located above the first accommodating space and a gap, the snapping buckle member is arranged in the first accommodating space, one end of the snapping buckle member has a snap hook bulging from the gap, and the driving member is arranged in the second accommodating space and is connected with a guide groove of the snapping buckle member through a guide hole. The fixing device disclosed by the invention can be operated by a single hand, can be rapidly mounted on the membrane type oxygenator or demounted from the membrane type oxygenator and can be arranged at a joint of a blood reservoir and a connecting rack without hindering connection between draft tubes and the blood reservoir / oxygenator and reading of blood volume graduations of the blood reservoir.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a fixing device for a membrane oxygenator. Background technique [0002] Membrane oxygenator is a commonly used medical device in cardiac surgery. Membrane oxygenator is usually fixed near the hospital bed by means of an external bracket when in use. During use, it is necessary to judge the index by reading the scale on the transparent shell of the oxygenator. At the same time, more guide tubes are often inserted outside the oxygenator for liquid exchange. At present, most of the fixing brackets used to fix the membrane oxygenator are metal ring structures, and the membrane oxygenator is supported and fixed by placing the membrane oxygenator into the metal ring of the fixing bracket from the top. When the membrane oxygenator is sleeved from the top into the metal ring for support and fixation, since there are many guide tubes inserted outside the oxygenator, it is easy to cause...
