Description

Artery puncture needle convenient to operate

Technical Field

The utility model discloses a belong to medical apparatus technical field, specifically be an artery pjncture needle convenient to operation.

Background

The artery puncture needle is used for puncturing and collecting arterial blood samples and carrying out dynamic blood gas/electrolyte and arterial blood pressure monitoring on critically ill patients, so that the samples can be obtained in time, the time is saved for rescue, complications caused by local injury due to repeated puncture can be avoided, the pain of the patients is reduced, and the dynamic observation of rescue, treatment and illness states is facilitated.

The arterial puncture needle generally comprises a indwelling tube and a puncture needle, wherein the indwelling tube is sleeved at the front end of the puncture needle. When the artery puncture is carried out, the puncture needle carries the indwelling tube to puncture the artery together, and then the puncture needle is pulled out, so that the front end of the indwelling tube is kept in the arterial blood vessel, and the subsequent operations such as invasive blood pressure monitoring or blood gas analysis are facilitated. Particularly, for invasive blood pressure monitoring, the conventional arterial puncture needle has a head of an indwelling catheter core which is generally aligned with the blood flow direction, and the definition of blood pressure is that the blood acts on the lateral pressure of a unit area of a blood vessel wall when flowing in the blood vessel, so that the accuracy of blood pressure monitoring by the conventional indwelling catheter is poor. In addition, the trailing end of the catheter is typically secured to the skin surface with tape after insertion into the artery to prevent dislodgement by patient movement or catheter pulling. When the existing puncture needle is connected with a sensor device, an artery needs to be pressed by one person, an assistant connects with the sensor, the operation is improper, the artery puncture needle can be folded in the blood vessel when being pressed, the separation can be caused sometimes, the assistant needs to be carried out by one person, the clinical workload is increased, and a lot of inconvenience is brought to medical staff.
