Background technique:

In clinical practice, it is often necessary to monitor the central venous pressure or intra-abdominal pressure for some patients to monitor the patient's physical status at any time. The central venous pressure is the pressure at the point where the superior and inferior vena cava enters the right atrium. The measurement unit of the right atrium intubation tube is generally centimeters of water (cmH2O), and the abdominal pressure is the pressure generated by the hydrostatic water of the abdominal organs, and the unit of measurement is generally millimeters of mercury (mmHg). At present, the commonly used method for measuring the pressure in the body cavity is: connect the infusion set to the physiological saline bottle and close the infusion set after exhausting the gas in the infusion tube, then connect the infusion tube to the catheter inserted into the patient's body, and clip the infusion tube into the body of the patient. In the groove of the pressure measuring scale, ensure that the zero-point scale line of the pressure measuring scale is at the same level as the pressure measuring standard point in the patient's body. Separate the infusion set from the physiological saline bottle so that the infusion tube is connected to the atmosphere. Turn on the flow regulator on the infusion tube. At this time, the liquid in the infusion tube flows into the patient's body. When the water column liquid level in the infusion tube drops to a stable level, the scale value of the pressure measuring scale corresponding to the water column liquid level is the pressure value. The patent No. ZL201820175463.5 fixes the ruler body on the infusion stand through the fixed wings on the transparent outer caliper, and sets the inner ruler with scale lines in the channel of the transparent outer caliper so as to facilitate the height Adjustment; this structure also requires medical staff to visually determine the height of the patient's chest pressure measurement standard point to adjust the height of the ruler, there is a certain error, and it is necessary to first fix the outer ruler on the infusion stand through the fixed wing, and then slide it up and down to adjust The height of the inner ruler is complicated in structure and cumbersome to use.
