Puncture needle positioning device for B-type ultrasonic examination

Abstract

The invention provides a puncture needle positioning device for B-type ultrasonic examination. The puncture needle positioning device for B-type ultrasonic examination comprises an adhesion tape, a stable table board and a positioning hole, wherein the stable table board is positioned on the top of the adhesion tape and is fixedly connected with the adhesion tape; the positioning hole is positioned in the middle of the inside of the stable table board, and is inlaid in the stable table board; adhesion layers are uniformly arranged on the bottom surface of the adhesion tape; limiting slots areformed in four corners of the top of the stable table board in an inlaid manner; a fixing column is inlaid in each limiting slot; the lower portion of the inside of each fixing column is fixedly connected with a damping spring; and the tops of the fixing columns are fixedly connected with a fixing table board. The puncture needle positioning device for B-type ultrasonic examination is provided with a sleeve, a channel for facilitating guiding can be provided for a puncture needle through the sleeve, the puncture needle can be rapidly inserted in a lump of a patient along with a puncture pointto aspirate liquid, meanwhile, after first-time liquid aspiration is finished, the puncture needle can be fixed in the body of the patient without manual assistance, the work efficiency is improved, and the puncture needle positioning device for B-type ultrasonic examination is suitable for production and use, and has good development prospect.

Description

Technical field [0001] The invention relates to the technical field of medical appliances, in particular to a puncture needle positioning device. Background technique [0002] The scope of B-mode ultrasound examination is very wide, and the preparation before examination is also different for different examination sites. [0003] Puncture is a medical surgical term. It is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for laboratory tests, gas or contrast agents are injected into the body cavity for contrast examination, or drugs are injected into the body cavity. The purpose of puncture is to draw blood for testing, blood transfusion, fluid infusion and catheter placement for angiography. [0004] The existing puncture needle positioning device cannot quickly locate the patient's puncture site, which wastes a certain amount of working time, and the positioning device does not have a component that can fix the punc...

AI Technical Summary

Problems solved by technology

[0004] The existing puncture needle positioning device cannot quickly locate the puncture site of the patient, which wastes a certain amount of working time, and the positioning device does not have a component that can fix the puncture needle, so that the doctor cannot stabilize the patient at the same time after the first pumping. The position of the puncture needle is a waste of manpower. Therefore, it is necessary to upgrade and transform on the basis of the existing technology to provide a puncture needle positioning device for B-ultrasound examination.
