The invention relates to the technical field of medical equipment, and specifically discloses a single-use filtration-type injection needle. The injection needle comprises a sheath, a needle tube, a needle seat, and a liquid medicine filter, wherein the needle tube is installed on the needle seat, the sheath sleeves the outer circumference of the needle seat, the needle tube is located in the sheath, the needle seat is connected with the liquid medicine filter, the liquid medicine filter comprises a shell and a filtering membrane, and the filtering membrane is arranged in the shell. The beneficial effects are as follows: on the basis of an ordinary injection needle composed of the sheath, the needle tube and the needle seat, the liquid medicine filter with the filtering function is added at the lower end of the needle seat, so that an injected liquid medicine passes through the liquid medicine filter to remove invisible particles, and then enters the human body.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a disposable filtering injection needle. Background technique [0002] Disposable sterile injection needles have been widely used clinically. When conventional injection needles are used in conjunction with disposable sterile syringes, the liquid medicine in the syringe is directly injected into the human body through ordinary needles. The possibility of pumping the liquid medicine The puncture debris and invisible particles in the injection syringe may be injected into the human body, causing discomfort or infection to the patient. For this purpose, we propose single-use filtered injection needles. Contents of the invention [0003] The object of the present invention is to overcome the problems of the prior art, and provide a disposable filtering injection needle with filtering function. [0004] The technical scheme adopted by the present invention to achieve t...
