Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a urinary catheter with the function of monitoring intra-abdominal pressure. Background Art

[0002] Abdominal pressure is the abbreviation of abdominal pressure. Abdominal pressure can be generated by muscle contraction, mainly by the contraction of the abdominal wall muscles and diaphragm to increase the intra-abdominal pressure. Straining, coughing, etc. will increase abdominal pressure. Generally, when abdominal pressure increases, people will feel abdominal distension. The main influencing factors are the heart, qi and blood, etc. Therefore, abdominal pressure can effectively reflect the patient's physical condition. However, in the existing technology, most urinary catheters do not have instruments that can directly monitor intra-abdominal pressure, which is not convenient for real-time monitoring of patients. When monitoring patients through indirect monitoring methods, the operation is more troublesome, time-consuming and labor-intensive, which increases the chance of abdominal infection and brings pain to patients. In addition, the material of the urinary catheter is relatively special, and it is difficult to replace it back and forth. The application number is "CN202320954906 .1" is a urinary catheter with the function of monitoring intra-abdominal pressure. In this utility model, when it is necessary to monitor intra-abdominal pressure, after emptying the bladder, the end of the outlet tube is clamped, and urine or saline flows into the outlet tube through a flexible tube. Then, through the monitoring tube, the urine or saline transmits the intra-abdominal pressure to the pressure measuring plate, which moves on the outer surface of the sliding rod, so that the intra-abdominal pressure can be obtained through the pressure sensor. However, this urinary catheter needs to be manually operated to perform a single intra-abdominal pressure monitoring when it is necessary to monitor the intra-abdominal pressure, and it is impossible to achieve real-time monitoring and accurately know the changes in the patient's abdominal cavity pressure.
