The specific use process
When the anti-reflux drainage device is used, the whole drainage bag 1 is in a vertical state, and under partial conditions, the drainage bag 1 can be obliquely placed or transversely placed, for example, when a cavity of the head of a patient is drained, the drainage bag 1 can be obliquely placed or transversely placed on a pillow on one side of the head of the patient. When the drainage bag 1 conducts drainage, body fluid sequentially flows through the upper drainage tube 3, the drainage bag 2, the soft plastic tube 201, the drainage bag 1 and the lower drainage tube. Because the water conservancy diversion mouth 202 sets up in the lower part of water conservancy diversion bag 2, and the diameter of water conservancy diversion mouth 202 and the pipe diameter of soft plastic tubing 201 are all greater than the internal pipe diameter of last drainage tube 3, when the body fluid is discharged from the patient through last drainage tube, water conservancy diversion bag 2 and soft plastic tubing 201, the liquid level of body fluid in the water conservancy diversion bag 2 can be avoided to above-mentioned structure is higher than the height of water conservancy diversion mouth 202 for the liquid level of body fluid in the water conservancy diversion bag 2 is less than the height of pipeline opening 303, thereby effectively prevents the body fluid in the water conservancy diversion bag 2 from flowing backward, simultaneously, and above-mentioned structure makes the body fluid volume that remains in the water conservancy diversion bag 2 be less than the volume of water conservancy diversion bag 2 greatly, can also play the effect of preventing flowing backward when water conservancy diversion bag 1 is placed obliquely, is put transversely and is put upside down.
When the drainage bag is obliquely placed or horizontally placed, the front surface of the drainage bag is kept upwards, so that the backflow of body fluid from the pipeline opening 303 caused by the downward direction of the pipeline opening 303 is avoided, the front surface of the drainage bag 1 is provided with a scale area 101, the effect of guiding a user to keep the front surface of the drainage bag 1 upwards is achieved, at the moment, body fluid in a patient is still discharged into the drainage bag 2 from the pipeline opening 303, the bulge 204 is attached to the inner wall of the drainage bag 1, and a space through which the body fluid can pass is formed between the drainage port 202 and the inner wall of the drainage bag 1 and between the soft plastic pipe 201 and the body fluid in the drainage bag 2 is conveniently discharged from the drainage port 202 and the soft plastic pipe 201; meanwhile, the accommodating cavity 304 plays a role in reducing the liquid level of the body fluid in the guide bag 2, the body fluid in the guide bag 2 is less in retention, and the pipeline opening 303 is positioned on the front surface of the upper drainage tube 3, so that the pipeline opening 303 is easily kept at a position above the liquid level of the body fluid, and the body fluid is prevented from flowing back from the pipeline opening 303.
When the drainage bag 1 is inverted, the valve 203 and the soft plastic tube 201 can be folded and closed under the extrusion action of the body fluid in the drainage bag 1, so that the body fluid in the drainage bag 1 is effectively prevented from flowing back into the drainage bag 2 through the soft plastic tube 201 and the valve 203; at this time, since the body fluid amount in the fluid guiding bag 2 is small and the pipe opening 303 is provided in the middle portion of the fluid guiding bag 2, the pipe opening 303 is easily maintained in a state higher than the body fluid level in this state, thereby preventing the body fluid from flowing back from the pipe opening 303.
The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
