Abstract
The present invention discloses a medical multi-head injection device, comprising: a needle seat and a needle sleeve; the needle seat comprises a drug guide tube, a medicine distribution plate and a needle; the end face of the needle sleeve at the end where the needle extends out is a parallelogram; the parallelogram comprises two first parallel sides and two second parallel sides; a plurality of needles are suitable for being evenly distributed along the trajectory direction of the first parallel side and the second parallel side; the distance from the needle close to the first parallel side to the first parallel side along the trajectory direction of the second parallel side is equal to half of the distance between the two adjacent needles along the trajectory direction of the second parallel side; the distance from the needle close to the second parallel side to the second parallel side along the trajectory direction of the first parallel side is equal to half of the distance between the two adjacent needles along the trajectory direction of the first parallel side. The medical multi-head injection device of the present invention can inject multiple needles at the same time, thereby improving the injection effect.
