Minitype negative pressure suction pumpTechnical field
The application relates to medical instruments field, especially relates to a kind of Minitype negative pressure suction pump for negative pressure drainage treatment.
Background technology
Facility is attracted mainly to comprise bedside central negative pressure source, vacuum suction equipment, negative pressure drainage vessel and Minitype negative pressure suction pump for negative pressure drainage treatment at present.
Head of a bed central negative pressure source negative regulation, but patient can only be confined on bed, cannot leave sick bed treatment, negative pressure treatment demand when can not meet patient activity.And vacuum suction equipment is larger and heavy, during treatment, noise is large affects patient's rest, simultaneously the same with head of a bed central negative pressure source, also can only meet and treat at the head of a bed.Although use when negative pressure drainage vessel is convenient to treat out of doors, need through conventional hands extruding, effort is inconvenient, and negative pressure is unstable, and in use procedure, negative pressure is more and more lower, and also easily leak air phenomenon.
Relative to other three kinds of vacuum suction facilities, Minitype negative pressure suction pump is convenient for carrying, and use, and it extrudes with hands without the need to patient when can meet patient activity, uses more convenient.But current Minitype negative pressure suction pump function is relatively simple, negative pressure test can only negative pressure in test bottle, cannot carry out Real-Time Monitoring, cause treatment accurate not to wound negative pressure.
