Rapid venipuncture device and using method thereof

Abstract

The invention relates to the technical field of venipuncture, in particular to a rapid venipuncture device and a using method thereof. The rapid venipuncture device comprises a guide line, an outer catheter and a needle cylinder, the needle cylinder comprises a hollow push handle and an empty cylinder, the push handle is slidably connected with the empty cylinder, and a puncture needle is connected to the end of the empty cylinder; an auxiliary bin is formed in the push handle, an anti-reverse valve I is arranged on an auxiliary plate, a rubber plug is fixedly connected to the inner end of the push handle, a blood storage bin is arranged in the empty cylinder, a plurality of channels are formed in the rubber plug, and the channels communicate with the auxiliary bin and the blood storage bin; and a skin expanding pipe is further arranged on the empty cylinder, the puncture needle is connected with the skin expanding pipe through an anti-reverse valve II, during use, the puncture needle is punctured into a blood vessel to enable blood to enter the blood storage cabin, a guide wire is manually made to penetrate through the push handle to enter the blood vessel through the needle head, the push handle is pushed to enable the skin expanding pipe to enter the skin, the guide wire is left, the whole device is drawn out, and then a reserved pipe is placed. According to the rapid venipuncture device, the time required for venipuncture can be shortened, the operation steps of workers are reduced, and the success rate of puncture is improved.

Description

technical field [0001] The invention relates to the technical field of venipuncture, in particular to a rapid venipuncture device and a use method thereof. Background technique [0002] Venipuncture is a technique commonly used clinically. Venipuncture is often used for blood sampling and infusion therapy. The commonly used arteriovenous trocar is mainly composed of a puncture needle and an outer catheter. In the target blood vessel, the guide wire is then inserted, then the puncture needle is withdrawn and the guide wire is retained, and then the skin is expanded to relieve the pain of the patient. Finally, the outer catheter is inserted along the guide wire, the guide wire is drawn out, and the catheter is retained; but this puncture The process is very complicated and requires high proficiency. Medical staff with less experience often fail to puncture successfully at one time, which increases the pain suffered by the patient and brings uneasiness and anxiety to both the m...
