Technical Field

[0001] The utility model relates to the field of medical technology, in particular to a urinary catheter capable of measuring bladder pressure. Background Art

[0002] During the diagnosis and treatment of patients, it is often necessary to measure bladder pressure. The current measurement method is: the patient first empties urine through a catheter placed in the body, and the nurse injects liquid (normal saline) into the bladder through the catheter until the maximum value that the patient can bear stops injecting, and then controls the switch to make the normal saline reverse the manometer to measure the pressure. In this process, since the catheter is often placed in the body, the catheter, syringe and manometer are connected together as a pressure measuring device.
