Description

Radial artery puncture catheter fixing device

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to radial artery puncture puts a tub fixing device.

Background

Invasive arterial blood pressure monitoring is a method for directly measuring arterial blood pressure by puncturing an artery, placing an arterial catheter into the artery of a patient, and connecting a pressure sensor and a monitor. Invasive arterial blood pressure monitoring mostly needs to convert pressure conducted by liquid into an electric signal by means of an invasive arterial pressure sensor, and finally, the electric signal is displayed on a display in a waveform mode, and data of systolic pressure, diastolic pressure and average arterial pressure are directly displayed. The continuous monitoring characteristic is suitable for various critical patients, and is widely applied to operating rooms, cardiac surgery and intensive care units to guide the formulation of treatment schemes and evaluate treatment in time. Invasive arterial blood pressure monitoring is generally performed by selecting a relatively large artery, such as a radial artery, a femoral artery, a brachial artery, an axillary artery and the like, wherein the radial artery is preferred, and the femoral artery is preferred. The radial artery of the wrist is in the longitudinal sulcus between the radial flexor carpus tendon and the lower end of the radius, the radial artery pulse can be touched on the upper and lower parts of the radial styloid process, and the position of the artery is superficial and relatively fixed, so that the puncture tube placement is easier, and the left radial artery is usually selected. However, since the position of the radial artery pressure measurement tube is at the movable position of the wrist joint, the fixation of the pressure measurement tube is easily affected after the limb of the patient is moved, which causes the occurrence of fluid seepage, blood seepage, needle slip, and the like, and directly affects the monitoring data of arterial pressure and the patient tube removal.
