Description
Technical Field
The utility model belongs to the technical field of medical device, concretely relates to artery pjncture needle propelling movement subassembly and artery pjncture needle external member that realize one-hand artery pipe propelling movement when the operation of artery puncture.
Background
In an intensive care unit, for critically ill patients with hemodynamics instability, a conventional noninvasive arterial blood pressure (NIBP) monitoring mode has certain limitation, cannot dynamically and accurately reflect the actual blood pressure level of the patients, and must carry out invasive arterial blood pressure (IBP) monitoring. Invasive arterial pressure monitoring refers to a method of directly measuring the blood pressure in an artery by placing an arterial catheter into the artery.
In clinic, the radial artery or dorsum pedis artery puncture method is mostly adopted for arterial catheter implantation. Taking radial artery as an example, the patient is in a flat lying position before the catheterization, the forearm is straightened, the palm is upward, and the back of the hand is bent by 60 degrees; during puncture, the radial artery pulsation is found, local anesthesia is infiltrated nearby the radial artery pulsation, the left hand touches the radial artery pulsation, the right hand punctures the artery, after blood return is observed through the blood return window, the left hand leaves the artery, the arterial catheter on the puncture needle is pushed into the artery to the required depth, then the needle core is pulled out, and the catheter is connected with a blood pressure monitoring device.
However, the wall thickness of the artery tube is easy to slide relative to the vein, and the puncture of the artery needle is difficult to put into the tube, especially for patients with shock, critical patients, severe peripheral vasoconstriction, high circulatory dysfunction and the like. Meanwhile, the artery is easy to slide, and once the left hand leaves the artery to operate the catheter, the puncture needle head is very easy to be influenced by the artery pulsation or slide due to unstable action of an operator, so that the puncture position has to be selected again to influence the puncture success rate.
In order to improve the success rate of puncture, the prior art also has a product of adding a guide steel wire into an arterial puncture needle, after puncture, the guide steel wire firstly enters an arterial blood vessel along the puncture needle, and then the arterial catheter is guided to be pushed into the artery to the required depth, but on one hand, the guide steel wire is easy to penetrate the blood vessel to influence the catheterization, and on the other hand, the price of the guide steel wire is dozens of times of that of a common puncture needle, and the use cost is high.
If in the process of puncturing, the left hand can touch the artery pulsation all the time, the slight fixation of the artery position is kept, the puncturing operation is carried out only by the right hand, the artery is fixed to a certain extent, meanwhile, the influence factors such as unstable action of an operator are eliminated, and the success rate of putting the tube is greatly improved. However, the prior art has focused on the improvement of the arterial puncture needle itself to improve the success rate of the insertion (e.g., CN201020683464.4), reduce the pressure on the skin (CN208785464U), and reduce the blood ejection during the tube insertion process (CN203693707U), but the tube insertion process still uses the prior two-hand cooperation tube insertion method, and no one has considered from the perspective of one-hand tube insertion.
