Intra-abdominal pressure measuring device

Abstract

The invention discloses an intra-abdominal pressure measuring device, relates to a medical device and solves the technical problems that an operation process of a conventional urinary bladder pressure measuring method is complicated and the measurement result is not accurate. The intra-abdominal pressure measuring device comprises a double-cavity catheter, a pressure measuring hose, an injector and a right-angle base, wherein the inner side of the right-angle base is a round notch, the pressure measuring hose is detachably arranged in the round notch of the right-angle base, scales are formed in the pressure measuring hose from bottom to top in the vertical direction, and the bent position of the side wall of the pressure measuring hose is the scale zero; a switch type tee is arranged at the upper part of the pressure measuring hose, and a speed adjusting valve is arranged below the switch type tee; a lower interface is formed in a lower port of the pressure measuring hose, the pressure measuring hose is connected with the double-cavity catheter through the lower interface, an upper interface is formed in the upper port of the pressure measuring hose, and the pressure measuring hose is connected with the injector through the upper interface. The intra-abdominal pressure measuring device is used for measuring the inner pressure in an abdominal cavity and has the advantages of being high in measuring accuracy and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to an intra-abdominal pressure measuring device. Background technique [0002] The intra-abdominal pressure is mainly generated by the contraction of the abdominal wall muscle and the diaphragm. Various diseases such as chronic peritonitis, intestinal obstruction, massive ascites, pancreatitis, intestinal edema after resuscitation, and certain abdominal operations can lead to increased intra-abdominal pressure. High pressure will produce a series of pathophysiological changes. [0003] At present, the monitoring methods of intra-abdominal pressure include direct manometry and indirect manometry. Clinically, intra-abdominal pressure is monitored indirectly by measuring bladder pressure. Cystometry is a simple and effective method to indirectly measure intra-abdominal pressure by indwelling a urinary catheter. During the measurement process of the traditional...
