| titleOfInvention | A blood collection needle and blood collection tube whose flow is controlled by a switch structure |
| abstract | The invention belongs to the technical field of medical devices, in particular to a blood collection needle and a blood collection tube whose flow is controlled by a switch structure. At present, when nurses collect blood, they can only quickly judge whether the blood collection volume reaches the marking line on the blood collection tube through experience. Nursing staff need to quickly disconnect the blood collection tube from the blood collection needle. has changed. The invention is provided with a jacket outside the blood collection tube, including a cover cover and a body cover, which are further divided into two half jackets, a left jacket and a right jacket. The scale line on the jacket is axially symmetrical; the blood collection needle is provided with a switch structure. In the present invention, various forms of switch structures and control methods are arranged on the blood collection needle, so that the blood collection volume can be better controlled, and auxiliary devices and structures that are easier to operate, such as scale lines set on the jacket, can make the blood collection volume in the blood collection tube more efficient. Accurate to lay the foundation for more accurate blood analysis results later. |
