Because the force in this case is opposite, the extrusion will not succeed. This kind of urine bag is generally recommended to be replaced within one week at most.
The catheter bag is connected to the catheter, which can discharge urine in time and become a container for temporary storage of urine. Catheter bags are generally disposable consumables and need to be replaced in time.
Urine collection bag is a sterile plastic bag specially made for patients with urinary incontinence. The urine collection bag is mainly used to collect and store urine for patients with urinary incontinence, coma, paralysis, concussion, stroke and after operation. It can also be used for elderly patients with urinary incontinence. When in use, urine is discharged into the urine collection bag through the drainage catheter. When the urine collection bag is full, urine can be discharged from the liquid outlet valve at the bottom of the urine collection bag. For example, the China utility model patent with the patent number of CN20 15209 13362 "Drainage bag liquid outlet cross valve". X, filed on 20 15 165438, discloses a drainage bag liquid outlet cross valve, which comprises a valve body and a valve core, and is characterized in that the upper end of a vertical pipe is provided with a liquid inlet, and the lower end of the vertical pipe is provided with a liquid outlet; The inner cavity of the horizontal tube is respectively communicated with the liquid inlet and the liquid outlet of the vertical tube; A valve core matched with the inner cavity of the horizontal pipe is inserted in the horizontal pipe; An annular groove is arranged on the middle front side wall of the valve core; An annular sealing ring integrated with the valve core is arranged on the side wall of the valve core near the valve stem near the annular groove. The valve core can be pushed back and forth in the inner cavity of the horizontal pipe. During operation, the index finger and middle finger of one hand are clamped on the upper and lower sides of the joint between the vertical pipe and the horizontal pipe of the valve body, and the thumb pushes the valve core to realize the opening and closing of the cross valve. The disadvantage of this cross valve is that it can't accurately control the pull-out position when the valve core moves backwards for 6 times, and it may pull out the whole valve core too hard, causing liquid leakage and polluting the ward environment.
