Embodiment Construction

[0039] The present invention will be further described with reference to the accompanying drawings.

[0040] This embodiment discloses an indwelling needle with the functions of blocking blood and preventing acupuncture, such as Figure 1~5 As shown, it includes a catheter adapter 1 and a steel needle adapter 2 connected to the catheter adapter 1. The front end of the catheter adapter 1 is fixed with an outer needle tube 3, and the catheter adapter 1 is also sleeved with a sheath 4. The steel needle adapter 2 is fixed There is a steel needle 5; the catheter seat 1 is provided with a valve core tube 6 and a plastic valve plate 7, and the lumen of the valve core tube 6 communicates with the liquid inlet channel in the catheter seat 1 to form a liquid channel; the valve core tube 6 One end of the valve core is closed by the plastic valve plate 7, and then closes the liquid channel; there is at least one of the valve core tube 6 and the plastic valve plate 7 that is slidingly arra...

Abstract

The invention discloses an indwelling needle with blood blocking and needling preventing functions. The indwelling needle comprises a catheter seat and a steel needle seat connected to the catheter seat, wherein a steel needle is fixed onto the steel needle seat; a valve core pipe and a plastic valve plate are arranged in the catheter seat, a pipe cavity of the valve core pipe communicates with a liquid inlet flow channel in the catheter seat to form a liquid channel; one end of the valve core pipe is sealed by the plastic valve plate, so that the liquid channel is sealed; at least one of the valve core pipe and the plastic valve plate is arranged in the catheter seat in a sliding manner; when the valve core pipe and the plastic valve plate move relatively, the valve core pipe punctures the plastic valve plate and enables the liquid channel to be in conduction; and a cavity is formed between the catheter seat and the steel needle seat, a sliding lock is arranged in the cavity and arranged on the steel needle in a sliding mode, and an elastic piece is further arranged in the sliding lock. The indwelling needle is simple in structure and convenient and practical in clinical operation and has the functions of blocking blood and preventing needling, and accidental puncture of a needle point is avoided while blood-derived pollution is avoided.

Description

technical field [0001] The invention relates to the field of medical devices, more specifically, it relates to an indwelling needle with the functions of blocking blood and preventing acupuncture. Background technique [0002] Intravenous infusion is the most common medical treatment method, and its basic principle is to inject liquid into the veins of the human body through infusion lines and hollow needles. To start the infusion, a hollow needle needs to be inserted into the vein. Due to the need to repeat the infusion many times, the puncture process needs to be repeated each time. [0003] In order to protect blood vessels, reduce blood vessel damage and mental pain caused by repeated punctures; facilitate patient activities and handling, reduce infusion leakage; keep venous access unobstructed at any time, which is convenient for timely drug delivery and emergency rescue; reduce the workload of nurses ,Improve work efficiency. Therefore, indwelling needles have been ...
