Abstract

The invention discloses an arteriovenous indwelling needle sealing plug comprising a sealing plug body and a cuboidal groove which is arranged inside the sealing plug body; the sealing plug body is a cylinder; the cylinder comprises two opposite circular end surfaces, i.e. a first end surface and a second end surface; the cuboidal groove comprises two opposite side surfaces, i.e. a first side surface and a second side surface; the circle center of the first end surface of the cylinder is arranged on the first side surface of the cuboidal groove; a linear hole slot is also formed between the second end surface and the second side surface; the direction of the opening of the hole slot is along the axial direction of the cylinder, and is communicated with the second end surface and the second side surface; the diameter of the hole slot is 0.1mm to 4mm. Due to the method, the invention provides the arteriovenous indwelling needle sealing plug, so that a catheter seat can be automatically sealed immediately after a needle is pulled out from an indwelling catheter, the problem of blood outflow is solved, not only can the pain of a patient who receives infusion be reduced, but also the phenomena of blood contamination and the like can be prevented, and benefit is brought to the mankind.

Description

technical field [0001] The invention relates to a tool for medical clinical use, in particular to a sealing plug for arteriovenous indwelling needles for medical clinical use. Background technique [0002] Arteriovenous indwelling needle is a medical device used for arteriovenous indwelling infusion. The arteriovenous indwelling catheter is composed of a steel needle made of stainless steel, a soft catheter and a catheter holder. A healthcare provider uses an indwelling vein to puncture a patient's arteriovenous vessels. After puncture, the steel needle needs to be pulled out from the catheter of the indwelling needle, and the softer catheter part is left in the patient's blood vessel for infusion. [0003] In order to prevent the blood from flowing out of the blood vessel after the steel needle is pulled out, pollute the puncture site, and even infect the medical staff, a sealing member is required to seal the catheter when the needle is pulled out to prevent blood from f...
