Description

Intra-abdominal pressure measuring device through bladder Technical Field The utility model relates to the field of medical tools, in particular to a device for measuring intra-abdominal pressure through a bladder. Background The abdominal cavity is a closed cavity, any increase in organ volume beyond a certain limit can lead to intra-abdominal hypertension, and elevated intra-abdominal pressure can lead to inter-abdominal compartment syndrome, leading to dysfunction of various organs, so that monitoring intra-abdominal pressure has important clinical guidance significance for diagnosis. The bladder pressure measured by the bladder has good correlation with the intra-abdominal pressure, and has the advantages of simple technical operation, small trauma, strong repeatability and operability, accurate measurement result and the like, and is the main mode of intra-abdominal pressure measurement at present. The specific method for measuring intra-abdominal pressure through the urinary bladder comprises the steps of inserting a urinary catheter through the urinary bladder of a patient in a supine position under a sterile condition, connecting two connected tee joints at the outer end of the urinary catheter, respectively connecting a syringe, a physiological saline bag and a pressure measuring device through three joints of the two tee joints, which are not connected with the urinary catheter, hanging the physiological saline bag, sucking the physiological saline into the physiological saline bag from the syringe after the urinary bladder is emptied, then injecting the sterile physiological saline within 30ml into the urinary bladder, and measuring pressure readings of the pressure measuring device after muscle of the urinary bladder is relaxed. The pressure measuring device comprises a pressure sensor and a host computer for data processing and displaying, wherein the pressure sensor is connected with the three-way joint, the pressure sensor converts a pressure signal transmitted by physiological saline into an electric signal, and the host computer converts the electric signal into pressure data for displaying. The pressure measuring device can also be a self-made tool, a common medical hose and a ruler are combined, the ruler is vertically arranged, the zero position of the ruler is aligned with the intersection point of the iliac spine and the axillary midline of a patient, the medical hose is connected with the three-way joint and is arranged along the ruler, the liquid level height in the hose is read, the bladder pressure value can be obtained, and then the intra-abdominal pressure is obtained. Professional pressure measuring equipment is not available in some hospitals, and the purchase cost is high. The self-made tool is used, so that the self-made tool is arranged more complicated, for example, the ruler is vertically fixed, the hose is arranged and fixed along the ruler, and the perpendicularity of the ruler is not easy to guarantee.
