Device special for drainage

Abstract

The invention discloses a device special for drainage. The device comprises a drainage pipe, an annular gasbag and a blocking head which is in sliding fit with the inner side wall of the drainage pipe; the upper end of the drainage pipe serves as a liquid inlet end, and the lower end of the drainage pipe serves as a liquid outlet end and is detachably connected with a drainage bag through a connecting joint; the gasbag fixedly sleeves the outer side of the drainage pipe and is arranged close to the liquid inlet end; an inflation pipeline communicated with an inner cavity of the gasbag is connected to the gasbag; an air inflation nozzle is connected to the inflation pipeline at the air inlet end, and a pressure adjusting valve is further connected to the portion, close to the air inlet end,of the air inflation pipeline; multiple drainage holes are formed in the section, between the air inlet end and the gasbag, of the drainage pipe in the length direction of the drainage pipe; the blocking head is in a shape of a bullet, and is arranged at the inner side of the liquid inlet end of the drainage pipe and connected with a silica gel strip, and the free end of the silica gel strip penetrates through the drainage pipe and penetrates out of the liquid outlet end. The device has a good fixing effect in the body of a patient, and does not easily fall off; meanwhile, the drainage smoothness of the device is good, and the drainage effect is ideal.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a special device for drainage.
