Abstract

The embodiments of the present invention relate to a venous puncture device. The device comprises a bracket, a carrying structure, an infrared module and a puncture module; the carrying structure isarranged on the bracket and used for carrying a puncture needle; the infrared module is arranged on the bracket and used for measuring a distance from a puncture needle tip to a venous blood vessel and an orientation of the venous blood vessel relative to the puncture needle by an infrared technology; and the puncture module is arranged on the bracket and used for moving the puncture needle intothe corresponding venous blood vessel according to the measured distance and orientation. The venous puncture device uses the infrared technology for positioning, doe not require manual blind punctureand can improve a puncture success rate compared with a body surface puncture technology.

Description

technical field [0001] The invention relates to the technical field of puncture, in particular to a venous puncture device. Background technique [0002] Venous vessels such as femoral vein, internal jugular vein, and subclavian vein are located under the skin and are sometimes not easy to find. In order to improve the success rate of venipuncture and reduce the pain of patients, the technology currently used is body surface marker puncture technology, which uses body surface markers as markers to manually perform venipuncture. It is a blind puncture, and the success rate of puncture is not high. Contents of the invention [0003] Based on this, it is necessary to provide a venipuncture device. [0004] A venipuncture device proposed in an embodiment of the present invention includes: [0005] bracket; [0006] The carrying structure is arranged on the support and is used to carry the puncture needle; [0007] The infrared module is used to measure the distance from th...
