Drainage bag

Abstract

The invention discloses a drainage bag comprising a drainage pipe, a drainage bag body, an exhausting pipe, a sewage discharging pipe and a rotary switch. The drainage pipe and the exhausting pipe are arranged on the upper surface of the cylindrical drainage bag body; the sewage discharging pipe is arranged on the lower surface of the drainage bag body; the rotary switch is connected to the drainage pipe; a Murphy's dropper is connected to the drainage pipe; the exhausting pipe is filled with absorbing substance; and a waterproof ventilating film is respectively arranged on the upper surface and the lower surface of the exhausting pipe. Smooth drainage can be achieved and inverted flow can be avoided; the drainage bag can precisely record data and can be conveniently used; and hands of nursing people cannot be contaminated.

Description

technical field [0001] The invention relates to a medical nursing appliance, in particular to a drainage bag. Background technique [0002] Patients with thoracoabdominal drainage or indwelling catheters often need to use drainage bags. At present, the shape of drainage bags used in hospitals is irregular ellipse or rectangle. In clinical care of patients, it is necessary to strictly and accurately record the patient's fluid discharge. After excluding the possible error caused by the specific gravity of urine (1.010~1.025) being greater than that of water (1.010), it was found that the scale of the drainage bag was (70±3) ml different from the scale of the actual urine volume. The greater the deviation, and the soft drainage bag cannot expand when there is not enough liquid to fill it, but it is in a collapsed state, resulting in a serious shortage of capacity. With the continuous increase of the amount of liquid, the drainage bag is filled and expanded, and the actual capac...

[0002] Patients with thoracoabdominal drainage or indwelling catheters often need to use drainage bags. At present, the shape of drainage bags used in hospitals is irregular ellipse or rectangle. In clinical care of patients, it is necessary to strictly and accurately record the patient's fluid discharge. After excluding the possible error caused by the specific gravity of urine (1.010~1.025) being greater than that of water (1.010), it was found that the scale of the drainage bag was (70±3) ml different from the scale of the actual urine volume. The greater the deviation, and the soft drainage bag cannot expand when there is not enough liquid to fill it, but it is in a collapsed state, resulting in a serious shortage of capacity. With the continuous increase of the amount of liquid, the drainage bag is filled and expanded, and the actual capacity exceeds The number shown on the scale prevents the nursing staff from accurately recording the data; due to the evacuation design of the drainage bag, the drainage in a dry state will make the drainage fluid not smooth, which may cause backflow and other phenomena
