Abstract

An intravesical pressure piezometric tube relates to the technical field of intra-abdominal pressure measurement and used for solving the problem that the conventional dual-cavity urinary catheter and piezometric tube are not matched in size and thus cannot be connected. The intravesical pressure piezometric tube comprises a head end, a tail end, a tube body and safe screw caps, wherein the tube body is a transparent hose with scales; each of the two ends of the tube body is provided with one cylindrical safe screw cap with an external thread; the head end and the tail end are respectively arranged on end surfaces of the safe screw caps; the head end is a barrel-shaped plastic part which is conoid as a whole, and comprises a guide part and a cylindrical mounting part; an external thread is arranged on the periphery of the mounting part; the tail end is a cylindrical plastic part; protective sleeves are respectively arranged on the peripheries of the front end and the tail end. The intravesical pressure piezometric tube is simple in structure and convenient to manufacture, can be connected with the dual-cavity urinary catheter conveniently and avoids unnecessary trauma to a patient caused by replacement of the urinary catheter during pressure measurement.

Description

technical field [0001] The invention relates to the technical field of measuring intra-abdominal pressure, in particular to a pressure-measuring tube for intra-vesical pressure. Background technique [0002] There are many critically ill patients admitted to the surgical ICU, many of whom have high intra-abdominal pressure, such as severe pancreatitis, multiple trauma, and abdominal tumors. Intra-abdominal pressure monitoring for such patients has become the consensus of all ICUs and has gradually developed. The monitoring of intravesical pressure through urinary catheter has been recognized as the gold standard for intra-abdominal pressure monitoring. [0003] However, there are some detailed problems in the actual operation of monitoring the intravesical pressure, because most of the indwelling urinary catheters in patients are double-lumen catheters, and the size of the opening of the double-lumen catheter does not match the size of the pressure measuring tube, resulting...
