Adjusting and fixing support for deep vein puncture needle for anesthesia

Abstract

The invention relates to the technical field of puncture needle supports, in particular to an adjusting and fixing support for for a deep vein puncture needle for anesthesia. The adjusting and fixing support comprises a rectangular frame, two U-shaped frames are symmetrically fixed to the two sides of the rectangular frame, binding belts are bound and fixed to the interiors of the two U-shaped frames, and transverse tensioning mechanisms used for tensioning the skin are arranged on the two sides of the rectangular frame. Two supporting rods are symmetrically and rotationally connected to the top face of the rectangular frame, guide rail holes are formed in the supporting rods, semicircular guide rail rings are inserted into the guide rail holes, the two ends of each guide rail ring are fixed to the top face of the rectangular frame, and elastic positioning mechanisms used for temporarily fixing the supporting rods to the guide rail rings are arranged in the supporting rods. According to the scheme, the skin at the puncture position is tensioned through the transverse tensioning mechanism, so that the loose skin is tightened, a doctor can see the meridians at the puncture position clearly, puncture is facilitated, the needle tube is clamped and fixed stably, the needle tube does not need to be held manually, and puncture operation is facilitated.

Description

technical field [0001] The invention relates to the field of puncture needle brackets, in particular to an adjustable and fixed bracket for deep vein puncture needles for anesthesia. Background technique [0002] Puncture, a term commonly used in medical surgery, is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, injecting gas or contrast agent into the body cavity for contrast examination, or injecting drugs into the body cavity. [0003] Some invention patents related to puncture needle brackets have been disclosed in the prior art. The Chinese patent with application number 202022025163.9 discloses a fixing device for puncture in anesthesiology department, including a bracket on which two first fixing shells and Two second fixed shells, and the two first fixed shells and the second fixed shells are symmetrically installed on the upper surface of the bracket respectively, a first moving rod is...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, when performing puncture, the puncture is mostly performed manually. The doctor manually operates for a long time, and the arm is prone to shaking, resulting in inaccurate puncture positions. There are also puncture needle supports in the prior art, but the existing supports It is bulky, fixed on the patient's body, and difficult to adjust during puncture. In view of this, we propose an adjustable fixed bracket for deep vein puncture needles for anesthesia
