Description

Botulinum toxin injection pen

Technical Field

The utility model belongs to the technical field of medical instrument, concretely relates to botulinum toxin injection pen.

Background

Botulinum toxin, also known as botulinum toxin or botulinum toxin, is a neurotoxin protein produced by Clostridium botulinum during reproduction. The toxin is divided into 7 serotypes A to G according to different antigenicity. Currently, botulinum toxin type a for injection is widely used clinically in various fields such as neurology, plastic surgery, dermatology, rehabilitation, urology, ophthalmology, and digestive department.

The pathogenesis of blepharospasm and facial spasm is not clear up to now. In recent years, it is considered that the blood vessel compresses the facial nerve. Clinically, the characteristic manifestations are strange, such as involuntary squeezing and closing eyes and facial muscle twitching. The attack is irregular, and the intermittent time is indefinite. It appears in early stage when the patient is active and emotional agitation, disappears in sleep, and becomes stable in late stage, and the disease course progresses progressively.

Acupuncture, physical therapy and spasmolytic medicines such as carbamazepine and phenytoin are applied for many years, the curative effect is not ideal, and the side effects of the medicines also cause that the treatment is difficult to last, the risk of the operative therapy is high, the technical requirement is high, and the medicines are often difficult to accept by patients due to craniotomy. The A type botulinum toxin is well accepted by patients who need to be treated by A type botulinum toxin injection for blepharospasm, facial spasm and the like due to the small side effect, quick response and lasting curative effect. However, the injection dose is too small to achieve the therapeutic effect, and the injection dose is too large to cause the over-treatment caused by muscle paralysis, so the strict control is required in the drug injection. However, no device for botulinum toxin injection exists in the prior art with precise control of dosage.
