Embodiment Construction

[0044] ginseng Picture 1-1 As shown, the puncture structure 001 described in the present invention with the function of observing blood return for medical purposes is shown here.

[0045] For the existing puncture structure, it mainly includes: the steel needle 011 inside the puncture needle, the outer cannula 012 of the puncture needle, the blood return sac 013 of the outer cannula, the side wings of the outer cannula 014, the observation window 015 and the blood return sac interface 016.

[0046] Wherein, the inner piercing needle 011 of the puncture needle is a sharp thin-strip pipe structure in the front section, which is generally a thin steel pipe. It is the main functional structure when puncturing the body. Its thickness can be flexibly set according to actual needs.

[0047] The puncture needle overtube 012, which is usually set on the periphery of the steel needle 011 in the puncture needle, is generally made of a flexible medical material suitable for indwelling, ...

Abstract

The invention discloses a puncture structure assembly with a medical blood returning observation function, which belongs to the field of medical devices, and relates to a medical puncture structure assembly. In the invention, a pipeline on the puncture structure or a related pipeline which is connected with the puncture structure and can direct conduct the blood is provided with a pipeline blocking body with a current limiting structure, and the equivalent conduction aperture of blood conduction of the current limiting structure is smaller than that of adjacent front and back pipelines thereof. The invention provides a great range of blood returning observation time so as to ensure medical workers to have sufficient time for observing the blood stream condition in the whole process of puncture and intubation, thereby increasing the success rate of puncture and intubation.

Description

technical field [0001] The invention belongs to the field of medical equipment and relates to a medical puncture structural component. Background technique [0002] The puncture structure of arteries and veins is a commonly used device in the medical field. Among them, the indwelling needle structure is particularly commonly used. The commonly used indwelling needle has a blood-returning vent plug on its needle seat to block the blood flow. Due to the limitation of the length and aperture of the observation window at the front end of the exhaust plug, when the indwelling needle punctures into the blood vessel, the observation window is quickly filled with blood, and the blood flow cannot be observed any more. Therefore, in clinical operation, a product that can have sufficient time to continuously observe the blood flow situation dynamically during the whole process of indwelling needle puncture and catheterization is needed. After relevant patent search, there is no rele...
