Abstract
The utility model discloses an automatic drainage device for generating negative pressure by using gravity. The automatic drainage device comprises a bottle body, wherein the bottle body is made of a hard material and is provided with a suspending device, the upper end of the bottle body is provided with an inlet, the bottle body is communicated with a drainage pipe, the lower end of the bottle body is provided with a piston, and the piston is connected with a negative pressure weight. The automatic drainage device has the advantages that the drainage device generates constant negative pressure by using the gravity without consuming any energy sources, the bottle body is made of the hard material so as to be difficult in deforming, and a scale is marked on the bottle body, so that drained liquid is measured accurately; the inlet is of a valve design, thus the drained liquid can be prevented from reversely draining; and the drainage device has a simple structure, is convenient and saves energy.
Description
Technical field
This utility model relates to a kind of drain, and specifically a kind of automatic jet device that utilizes gravity to produce negative pressure belongs to field of medical.
Background technology
After surgical operation is accomplished, needing to place drain, often is to connect negative pressure drainage vessel or drainage bag through drainage tube, with the tissue blood in drainage district etc.Common clinically drainage system is to utilize spring or electric power to produce the drainage device of negative pressure, and material is soft design, spring and flexible wall incarceration often occur, loses drainage.And the drain metering is inaccurate, and the adverse current phenomenon takes place simultaneously easily, has influenced the effect of drain.
