Abstract

The invention relates to a precision subcutaneous injection auxiliary device, and belongs to the technical field of medical apparatuses and instruments. The precision subcutaneous injection auxiliary device is composed of a cylinder, an exhaust device, an injection window and a closed sticker. The bottom of the cylinder is open, the top of the cylinder is connected with the exhaust device, the injection window is arranged on the cylinder wall of the cylinder, and the injection window is covered with the closed sticker. The precision subcutaneous injection auxiliary device has the advantages that subcutaneous tissue and muscular layers can be greatly separated through vacuum aspiration, and precision subcutaneous injection can be achieved on the portions such as the back. Negative pressure can be generated conveniently, the skin can be lifted conveniently and rapidly, and the auxiliary device and the skin can be rapidly separated by conveniently and rapidly eliminating negative pressure; by arranging the injection window, the injection window is provided with the replaceable closed sticker, the closed sticker can close the injection window, and the post-injection hemostasis function is achieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary device for precise subcutaneous injection. Background technique [0002] Subcutaneous injection is the injection of a liquid medicine into the subcutaneous tissue. Commonly used injection sites are the upper arm and lateral thigh. With the introduction of new technologies and the emergence of new needs in clinical practice, the use of subcutaneous injection of ultrasound contrast agent for sentinel lymph node examination is conducive to the assessment of malignant tumor staging, to guide the degree of local lymph node dissection, and to improve the quality of patients after surgery. quality of life. The primary condition for contrast-enhanced ultrasonography of sentinel lymph nodes is to accurately inject the contrast agent into the local subcutaneous tissue, so that the contrast agent can accurately flow back to the lymph nodes through the lymphatic vessel...
