Background

Invasive arterial pressure monitoring is a method of directly measuring the pressure in the lumen of an artery by placing a catheter into the artery. In clinical medicine, arterial blood pressure is monitored invasively, and is commonly used for monitoring blood pressure changes of patients with surgical anesthesia and intensive care in real time, so that vital sign conditions of the patients are known in real time through the changes of the arterial blood pressure, and the vital sign conditions are processed in time.

The existing invasive arterial pressure measuring method adopted in hospitals is that after percutaneous arterial puncture is placed in a tube, pressure is transmitted to a pressure monitoring sensor device through a connecting pipeline, the sensor device is matched with a monitor for application, and a blood pressure value is displayed through the monitor.

The existing arterial pressure measurement mode is as follows: as shown in figure 14 of the specification, the outer sleeve of the puncture needle is placed in a blood vessel through the skin, the three-way knob valve is screwed to the BD direction to enable blood to enter the pressure sensor through the outer sleeve of the puncture needle through the outer connecting pipe, and pressure is transmittedThe sensor performs measurement, and the pressure sensor measurement data is transmitted to the monitor through the cable to display the pressure value. The arterial catheter is kept in the arterial vessel of puncture position to external sensor device connecting line, to the patient who needs to carry out long-time real-time monitoring, long-time intravascular catheter is detained, and clinical common problem has:

causing vascular catheter-related infections (local or systemic) and hematogenous infections; />

Although the anticoagulation medicine is used for flushing the pipeline (intermittent or continuous) in clinic conventionally, the pressure measuring pipeline is blocked due to the coagulation block for a plurality of reasons, and the displayed value cannot be measured normally.

Disclosure of Invention

the utility model provides a novel arterial pressure monitoring device, includes guide needle, bush core, sheath pipe, tee bend knob valve, pressure sensor and monitor, but bush core and sheath pipe draw-out insert in the guide needle, and the sheath pipe is flexible, and inflation sacculus is connected to flexible sheath pipe one end, and tee bend knob valve and pressure sensor are linked together in proper order to other one end, and pressure sensor links to each other with the monitor.

The sheath tube is communicated with the three-way knob valve through the luer connector and the connecting tube.

The guide needle is provided with a plurality of circles of grooves.

The leading needle tip is bent upward.

The sheath tube and the sensing saccule are made of PVC, silica gel or TPU.

The beneficial effects of the utility model are as follows: the guide needle, the pressure measuring sheath tube and the sensing saccule do not enter the blood vessel of the patient, so that the trauma to the patient is smaller, and the risk of blood path infection is avoided; the sensing saccule and the outer pipeline are filled with liquid, which can be physiological saline or other liquid harmless to subcutaneous tissue, so that the condition that the pressure measuring pipeline is blocked due to coagulation in the traditional scheme can not occur.
