Description

Needle head injector

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a syringe needle syringe.

Background

Scars are a collective term for the morphological and histopathological changes in the appearance of normal skin tissue caused by various skin injuries. Is a necessary product in the process of repairing human body wounds. Scars can be classified into hypertrophic scars, keloids, atrophic scars and keloid carcinoma according to anatomical morphology. Keloid scars are a special category of pathological scar tissue that overgrows, can follow skin trauma or spontaneously develop, and are characterized by lesions that extend beyond the original skin lesion, grow persistently, appear to be raised above the skin surface, are hard in texture, engorge nodular, stringy or flaky lump-like tissue, can be accompanied by itching or pain, and are characterized by resistance to treatment and a high rate of recurrence after treatment. Therefore, keloid is one of the diseases which are difficult to be clinically treated in the fields of surgery and dermatology.

The existing treatment modes of keloid comprise: the method comprises the following steps of operation treatment, radiation treatment, drug treatment (local injection: glucocorticoid hormone, antineoplastic drugs such as 5-fluorouracil, bleomycin and mitomycin, type A botulinum toxin, verapamil, oral administration; external drug; glucocorticoid dissolving microneedle technology), laser treatment and laser auxiliary drug delivery technology, pressure treatment, silica gel preparation, photodynamic therapy, epidermal transplantation, fat transplantation, stem cell transplantation, tissue engineering skin and the like. Among them, injection of scar internal medicine is one of the main treatment methods of keloid.

The method for injecting the medicament in the scar comprises the following steps: the injection method is carried out by a free-hand injector, a low-pressure injector without a needle head and an injector with a booster. At present, the clinical conventional syringes which are used more adopt a multipoint local injection mode, and the manual injection is harder and difficult due to harder scars, so that the needle head and the needle tube are separated easily due to the manual injection and the application of the booster, and the liquid medicine is lost and splashed. The low-pressure injector without the needle head has the disadvantages of high price, easy blister, difficult fixation when injecting scar at a special part and more medicine infiltration.

SUMMERY OF THE UTILITY MODEL
