Subclavian venipuncture locator

Abstract

Disclosed is a subclavian venipuncture locator. The subclavian venipuncture locator is characterized in that a dangerous-zone indication portion is arranged at the position of the inner end of a base plate, the dangerous-zone indication portion is of a right triangle with the edge a-b perpendicular to the edge b-c, the edge a-b is located at the upper edge, the point a is located at the position of the inner end, the distance between the point b and the point a is 5cm, the length of the edge b-c is 3cm, a positioning piece is slidably connected to the lower edge of the base plate through a slide rail, an injection orifice is arranged in the positioning piece, a first injection point, a second injection point and a third injection point are respectively marked on the slide rail, the distance between the first injection point to the inner end is 5cm, the distance between the second injection point and the inner end is 8cm, the distance between the third injection point and the inner end is 11cm, a first guiding line, a second guiding line and a third guiding line are drawn on the base plate, wherein the first guiding line is the connection line between the first injection point and the point a, the second guiding line is the connection line between the second injection point and the point a, and the third guiding line is the connection line between the third injection point and the point b.

Description

technical field [0001] The invention relates to a medical auxiliary tool, in particular to a subclavian vein puncture positioner. Background technique [0002] Subclavian vein puncture is a very important operation technique when rescuing patients. It can significantly improve the success rate of rescue and is very important for saving patients' lives and gaining time for rescue. However, subclavian vein puncture is still a kind of Blind detection operation needs to rely on the doctor’s experience and feeling. It is possible that the subclavian vein cannot be found correctly after repeated punctures. If the puncture depth is not well grasped, the needle tip used for puncture may even pierce the patient’s lung apex. , very dangerous. For this reason, some hospitals even use B-ultrasound as a guide to carry out puncture operations, which not only increases the cost, but more importantly, prolongs the rescue time. [0003] However, there is not much individual difference in t...
