Disposable single hand insertion tube type vein detaining needle

Abstract

The invention relates to a disposable single hand insertion tube type vein detaining needle (shown as in the abstract drawing) which can simplify the operation process of a nursing technique, improve the venipuncture success rate, relive patients' pain and save medial treatment materials. On the basis of the original vein detaining needle, the handle of the detaining needle is transformed into an anastomosis handle, the anastomosis handle extends forwards about 2 mm, two longitudinal semicircular bulges are designed on the upper surface of the anastomosis handle, a miniature baffle plate is additionally arranged on the rear edge of the lower surface of the anastomosis handle, four protuberances are designed on the lower surface of the anastomosis handle, an anastomosis side wing is additionally arranged on a trocar bed of the indwelling needle, two semicircular grooves are designed in the lower surface of the anastomosis side wing to be matched with the longitudinal semicircular bulges on the upper surface of the handle, a miniature baffle plate is additionally arranged on the front edge of the anastomosis side wing, and four protuberances are designed on the lower surface of the anastomosis side wing. During venipuncture, after blood returning, a cannula is pushed into a vessel by the thumb of a right hand without the need of exchanging hands, so that the delivering of a detaining needle cannula by a single hand can be achieved, the operation process is simplified, the vessel is not liable to puncture, the success rate is improved, and the patients' pain is relieved.

Description

technical field

[0001] The invention is a medical material that can simplify the operation process of nursing technology, improve the success rate of venipuncture and relieve pain of patients. Background technique:

[0002] The needle of the disposable venous indwelling needle (as attached to the instruction manual) used by medical and health units at present figure 1 , attached figure 2 ), currently clinically, there are two procedures for blood vessel puncture using this venous indwelling needle:

[0003] 1. The commonly used puncture procedure. When puncturing, the right hand is responsible for puncturing, and the left hand is responsible for straightening the skin and blood vessels at the puncture site. When blood returns, the right hand holds the indwelling needle forward about 2 mm, and at this time holds the indwelling needle in the right hand to fix it. Do not move, because the current clinically used venous indwelling needles do not have a one-handed tube deliver...
