Blunt needle for subcutaneous injection

Abstract

The invention discloses a blunt needle for subcutaneous injection. The top end of the blunt needle for injection is a smooth curved surface body, the part under the smooth curved surface body is of apipe body structure, through holes with elliptical outer surfaces and circular inner surfaces are formed in the pipe wall of a pipe body, and the side view of each through hole is in a dome shape; theblunt needle is made of a semi-rigid material, and any part of the pipe body can be bent to 90 degrees; the pipe wall of the pipe body is provided with the 2-4 through holes with elliptical outer surfaces and circular inner surfaces, and the 2-4 through holes with elliptical outer surfaces and circular inner surfaces are near to the top end of the blunt needle; the semi-rigid material is Japanesesteel SUS304DE, and a tapered pipe for transitional connection is arranged at the other end of the pipe body. The blunt needle for injection has the characteristics that the structure is simple, theuse is convenient, the surgical effect good, solvents and medicament can be enabled to be slowly ejected from the holes instead of being spurred out all at once without pressing and hurting nerves andblood vessels, any burden is hardly brought to human bodies, and the injection can be carried out uniformly in a large area.

Description

technical field [0001] The invention relates to the technical field of medical and beauty appliances, in particular to a blunt needle for local anesthesia or fat dissolving, hyaluronic acid, PRP injection and other injections. Background technique [0002] In the prior art, the traditional injection needles used in beauty and body beauty clinics use muscle and subcutaneous puncture injections. Since the front end of the traditional injection needle is a tapered blade, and a drug injection hole is directly provided at the front end, the force is not accurate enough when puncture injection. , the transmission speed of injection pressure is too fast, and the drug is also released too fast during the pushing process, which often causes acupuncture to damage blood vessels and nerves, or the speed of drug transmission under injection pressure is too fast, causing instantaneous damage to the surgical site or surrounding tissues and blood vessels. and nerve damage, which makes some ...
