technical field

The utility model relates to a medical nursing appliance, in particular to a non-contact volume measuring body fluid drainage bag.

Background technique

Patients with thoracoabdominal drainage or indwelling catheters often need to use drainage bags. In clinical care of patients, it is necessary to strictly and accurately record the patient's fluid discharge, and judge the patient's wound recovery based on the patient's body fluid discharge.

The disposable drainage bag used in the medical work at present is only simply used to draw out postoperative peritoneal fluid, dirty fluid, blood and some other watery objects. Because most of the body fluids are viscous, on the one hand, the solution sticks to the drainage bag, causing the drainage bag to appear darker in the middle and lighter at the edge, and because most of the drainage bags are soft, the distribution of body fluids is difficult for clinical diagnosis. The volume cannot reflect the true situation of the body fluid, which brings inconvenience to clinical diagnosis. In addition, it is also possible to measure the volume in other measuring containers after the body fluid is discharged. However, due to the viscosity of the body fluid, the body fluid adhering to the drainage bag cannot be discharged, causing errors in the measurement, and if further testing is required, the discharged body fluid is easily affected by the outside world. Environmental pollution makes the test results inaccurate.
