Problems solved by technology

[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.

Example Embodiment

[0017] In the following, we illustrate the present invention in detail through specific implementation cases:

[0018] Such as figure 1 The drainage bag shown includes a cylindrical drainage bag body 2, and a drainage tube 1 and a sewage pipe 4 are fixed and sealed on the central axis of the upper surface and the lower surface of the drainage bag body 2, respectively; the drainage bag body 2 It is made of soft plastic, and the edges of the upper and lower surfaces are each provided with an elastic support 21. The elastic support 21 effectively supports the drainage bag into a cylindrical shape, which can be folded and twisted at will and has a certain degree of pressure resistance. A longitudinal scale 22 is designed on the outer surface of the drainage bag body, the maximum value of the scale is 900ml, and the maximum capacity of the drainage bag is 1000ml. The drainage tube 1 is successively installed with a Murphy's dropper 12, a rotary switch 5 and a pipe connector 11 from bo...

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...
