Collecting device for drainage liquid and seepage liquid

Abstract

The invention relates to a collecting device for drainage liquid and seepage liquid. The collecting device comprises a first collecting bag and a second collecting bag, wherein the first collecting bag has a fistulization bag structure; a guide pipe which is used for communicating the first collecting bag with the second collecting bag is connected between the first collecting bag and the second collecting bag; one-way conduction switches are respectively arranged on an upper end part of the guide pipe, the middle and lower end parts of an inlet part connected with the first collecting bag and an outlet part connected with the second collecting bag; a draining valve which is communicated with an inner chamber of the second collecting bag is arranged at the bottom of the second collecting bag; the first collecting bag, the second collecting bag and the guide pipe are integrated into a whole; the inlet of the first collecting bag is covered on a stoma of a patient, a drainage pipe is inserted into the inlet of the collecting bag, the seepage liquid between the stoma and the drainage pipe and the drainage liquid drained from the drainage pipe can be collected by the second collecting bag, and when the liquid collected in the second collecting bag is almost full, the draining valve thereon is opened, so that the collected liquid can be drained. The one-way conduction switches arranged in the collecting device can prevent the backflow phenomenon of the liquid in the second collecting bag or the guide pipe.

Description

technical field [0001] The invention relates to a postoperative drainage device, in particular to a drainage fluid and exudate collection device. Background technique [0002] For patients after thoracic and abdominal surgery, drainage tubes and drainage bags (or drainage balls) usually need to be indwelled. In order to deal with the exudate between the stoma and the drainage tube, there are two methods currently used. One is to pad gauze in the gap between the stoma and the drainage tube to absorb the exudate; The fistula bag covers the stoma, and then a collection bag is connected to the fistula bag cover through a section of catheter, and the collection bag collects exudate and drainage fluid discharged from the drainage tube. Among the above two methods, the shortcomings of the former are: the gauze needs to be replaced frequently, which increases the workload and cost of nursing; it is not conducive to observing the skin around the drainage tube; the soaking of the exu...

Problems solved by technology

Among the above two methods, the shortcomings of the former are: the gauze needs to be replaced frequently, which increases the workload and cost of nursing; it is not conducive to observing the skin around the drainage tube; the soaking of the exudate will irritate the skin around the drainage tube, which is easy to cause stoma infection

The shortcomings of the latter are: when the patient turns over or gets out of bed, the exudate in the collection bag or catheter is prone to reflux, causing retrograde infection; the collection bag needs to be replaced frequently. During the replacement of the collection bag, the collection bag and the catheter The operation of separating the connection is more troublesome
