Arteriopuncture auxiliary device with arm stabilizing function

Abstract

The invention relates to the technical field of arteriopuncture, in particular to an arteriopuncture auxiliary device with an arm stabilizing function, an adjusting and stabilizing mechanism and a puncture positioning mechanism are arranged on a base, the arm of a patient can be stably fixed through mutual cooperation of the base and the adjusting and stabilizing mechanism, and the fixing effect is good; moreover, adjustment can be carried out through the adjusting and stabilizing mechanism according to the specific arm condition of a patient, the adaptability is good, the arm stability during puncture is guaranteed, after the arm is stabilized, the puncture deviation during puncture can be avoided through the puncture positioning mechanism, and the puncture accuracy is improved. And medical staff can stably position the puncture needle through the puncture positioning mechanism and puncture the patient, so that the puncture stability is ensured.

Description

Technical field: [0001] The invention relates to the technical field of arterial puncture, in particular to an arterial puncture auxiliary device with a function of stabilizing an arm. Background technique: [0002] Arteries refer to blood vessels that transport blood from the heart to various parts of the body. When the patient is in severe shock and the condition does not improve after rapid intravenous blood transfusion, arterial puncture is required to increase coronary perfusion and increase effective blood volume, or Arterial puncture is required for special examination or treatment of patients, such as blood gas analysis, cardiac catheterization, and hemodialysis treatment. Radial artery puncture is a common medical technique. The location of the artery is usually deep, and Accompanied by pulsation, the blood vessel is easy to slide during puncture, and the puncture needle cannot easily penetrate the blood vessel. In clinical practice, in order to accurately puncture ...

AI Technical Summary

Problems solved by technology

[0003] At present, when performing arterial puncture, the patient's wrist should always be kept in a supine state, and the wrist should be bent at a certain angle so that the medical staff can better find the artery for puncture. The patient's arm often has to maintain this posture for a period of time. However, the arm cannot be stabilized during the puncture process. The patient's wrist often moves due to conditioned reflex, which changes the position of the artery, which may lead to puncture failure or affect the puncture effect. Moreover, medical staff perform manual puncture based on experience. When performing puncture, there may still be deviations during puncture. In order to keep the patient's arm in the required posture for a certain period of time, the existing fixation method generally uses a support pad under the arm and wrist and is tied with a bandage. Although the patient's arm and support pad have achieved a certain fixation effect, the fixation effect is poor, and the patient's arm cannot be stabilized well, and it cannot be adjusted according to the patient's specific arm condition during use. The compatibility is low, and at the same time, the stability of the arm after arterial puncture cannot be guaranteed, and its use has certain limitations; although some hospitals use a radial artery arm puncture support device, the traditional device has certain disadvantages, and it cannot be used according to the patient's needs. Adjust it according to the specific situation, the comfort is low, and there are certain defects in use, so it is necessary to develop an arterial puncture auxiliary device with the function of stabilizing the arm
