Artery puncture needle

Abstract

The invention discloses an artery puncture needle. The artery puncture needle comprises a needle handle, a needle tube and a plugger. The upper end of the needle handle is provided with a storage buffer tube connected with a through hole and further provided with a side hole including a first side hole body and a second side hole body. The plugger comprises a sliding shaft, wherein the sliding shaft penetrates through the first side hole body, one end of the sliding shaft is provided with a button, the other end of the sliding shaft is connected with a check block which is located in the second side hole body, the width of the check block is larger than that of the first side hole body, a spring is arranged on the portion, between the button and the outer side of the needle handle, of the sliding shaft, and the sliding shaft is also provided with a connecting hole; under the action of external force, the button is compressed or loosened to drive the sliding shaft to block or allow connection between the needle tube and the through hole. According to the artery puncture needle, the needle handle of the artery puncture needle is provided with the side hole, and the plugger with the spring is arranged, so that the phenomenon of a short gush of blood in the pulse puncture process in the prior art is effectively overcome to ensure smooth implantation of a catheter or a guide wire in the follow-up process; moreover, the artery puncture needle is easy to operate, low in cost and easy to realize, and has popularization and application value clinically.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an arterial puncture needle. Background technique [0002] Arterial puncture is a commonly used treatment method in clinical practice. The arterial puncture needle used clinically, especially the arterial puncture needle in the aortic balloon counterpulsation pump set has no control button. After successful arterial puncture, it cannot effectively block the Arterial blood flow spurts out, causing bed sheet contamination, blood loss in patients, causing panic in patients and their families, increasing the risk of puncture, and may even aggravate the patient's condition due to blood loss. After insertion, before the guide wire is placed, arterial blood is often spurted out due to high arterial pressure, which may contaminate the bed unit, or cause blood loss and aggravate the patient's condition.
