Description

A simple pressure measuring tube

technical field

The utility model relates to the field of medical equipment, in particular to a simple pressure measuring tube.

Background technique

Measuring the intra-abdominal or venous pressure of the human body is an indispensable operation in the treatment of diseases. For example, it is necessary to monitor the central venous pressure for some seriously ill or major surgery patients. Stressful situations adjust the treatment plan to facilitate better treatment of the disease.

The methods used for pressure measurement in the prior art include: using a special pressure measurement device, or using an extension tube to monitor the pressure, both of which have disadvantages: the use of a dedicated pressure measurement device is expensive and increases the burden on patients. , and it needs to be installed before pressure measurement, which is inconvenient to use; although it is simple and convenient to use the extension pipe to monitor, the extension pipe is only a temporarily used pipe, generally there is no scale size, and a ruler needs to be used to measure the extension pipe. It is prone to the problem of cross infection of patients caused by lax disinfection of the ruler. In addition, the monitoring of intra-abdominal pressure mostly uses bladder pressure monitoring to indirectly measure intra-abdominal pressure. Since there is no suitable pressure measuring tube, the urine bag is often used to cut off the bag body, and the remaining part of the urine bag is used for pressure measurement, which is easy to contaminate the pipeline. The manometry process also increases the workload of nurses.
