The invention discloses a needle head hidden type syringe with an adjustable injection depth. The needle head hidden type syringe comprises an injection pipe and a hidden needle head, wherein a pressure pipe is arranged in the injection pipe; a rubber extrusion head is fixed on the inner end face of the pressure pipe; a fixing table and a fixing casing are fixed at two ends of the injection pipe; the fixing casing is fixed at one side of the fixing table; an adjustable outer cover is connected to the top end of the fixing casing; the adjustable outer cover is fixed with the fixing casing by a positioning part; a hidden inner cover is fixed at the other end of the adjustable outer cover; the hidden inner cover is connected with the adjustable outer cover by a spring; a pressure head is arranged inside the adjustable outer cover; the hidden needle head is connected to the other end of the pressure head; a through hole for the hidden needle head to be stretched out and drawn back is reserved in a central position of the top surface of the hidden inner cover. According to the needle head hidden syringe with the adjustable injection depth, the depth of the needle head injected into skin is precisely controlled by adjusting the end face of the adjustable outer cover after assembly is ended. The safety of a product in a use process is greatly improved.
Description
technical field [0001] The invention relates to a syringe, in particular to a needle concealed syringe with adjustable injection depth, which belongs to the technical field of medical instruments. Background technique [0002] Most of the existing injection needles are directly inserted into the needle, and the needle is exposed outside, which is easy to cause fear and psychological pressure when the patient uses it; at the same time, it is difficult to accurately control the injection depth because the medical staff cannot control it properly; thus it may lead to inaccurate injection . Simultaneously because the needle is outside, without any protective device, when the patient uses it, it is easy to cause other unnecessary injuries. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects that the needle is exposed outside, easily causing fear, and it is difficult to accurately control the injection depth,...
