Description

Support fixing sleeve

Technical Field

The invention relates to the technical field of puncture equipment, in particular to a support fixing sleeve.

Background

At present, most medical personnel adopt a blind puncture method when blood vessel puncture is carried out, the blind puncture has high requirements on the experience of the medical personnel, the puncture failure probability is high, if the puncture fails, other blood vessels can be damaged, and the pain of patients is aggravated. Some hospitals begin to use ultrasound for guided puncture, and three common methods are mainly used for the ultrasound guided puncture: (1) blind puncture under ultrasonic guidance; (2) guiding puncture by using a metal puncture frame; (3) plastic puncture stents were used to guide the puncture. Wherein, the blind wearing under the ultrasonic guidance has the following several shortcomings: (1) medical care personnel are required to have certain puncture experience, and new medical care personnel need to learn and adapt for a long time; (2) the direction guiding device is not arranged during puncture, the puncture depth is not well controlled, if the puncture angle is not right, the puncture needle needs to be retracted to find the angle for needle insertion again, and the pain of a patient is deepened. The metal puncture frame is used for guiding puncture and has the following defects: (1) most of the metal puncture frames are not disposable, and if the sterilization link is in trouble, more harm can be brought to patients; (2) if the metal puncture frame contacts with a patient, the cold feeling of the metal can make the patient feel nervous and uncomfortable, and the puncture difficulty of medical staff is increased. The plastic puncture bracket is a better method for guiding puncture at present, but if the plastic puncture bracket is used for guiding puncture, a probe of the ultrasonic equipment is required to be provided with a buckle matched with the plastic bracket, few manufacturers have the probe at present, the probe with the buckle is generally only provided with one buckle in the long edge direction of the probe, and only in-plane method puncture can be carried out when the plastic puncture bracket is used.
