Abstract

The invention relates to the technical field of medical beauty operation equipment, and discloses a disposable injection device with a depth adjustable function for medical beauty surgery. The disposable injection device comprises a needle tube and a needle head arranged at the top of the needle tube, an adjusting mechanism for adjusting the pricking depth of the needle head is arranged outside the needle tube, the adjusting mechanism comprises a sleeve, and a threaded rod is arranged on the inner side surface of the sleeve. The threaded rod rotates to drive a threaded block to move, the threaded block moves to drive the needle tube to move, and the needle tube moves to drive the needle head to move, so that the extension length of the needle head can be adjusted, and a nurse can conveniently control the pricking depth when pricking the needle; and meanwhile, an elastic bag is compressed to eject gas to drive an impeller to rotate, therefore, power can be provided for rotation of the threaded rod, and the threaded rod can be driven to rotate slowly, so that the extension length value of the needle head is more accurate, and the situation that the nurse cannot control the pricking depth accurately due to lack of practice to bring strong discomfort to a patient is avoided.

Description

technical field [0001] The invention relates to the technical field of medical aesthetic surgery equipment, in particular to a disposable injection device for medical aesthetic surgery with a depth-adjustable function. Background technique [0002] In recent years, with the continuous advancement of the construction process of my country's medical device industry, various products have emerged in an endless stream, but the technological improvement reflected in the syringe industry has almost stagnated. For more than ten years, the syringe has basically followed the past style, resulting in the current hospital and There are many inconveniences in the use of beauty institutions. [0003] During the use of existing syringes, the penetration depth of the needle tube cannot be adjusted according to actual needs, which has caused some unskilled or insufficiently skilled nurses to have needles that are too deep or too shallow when performing needle injections. In addition, for so...
