Description

Medical adhesive applicator

Technical Field

The invention relates to a medical adhesive smearing device, in particular to a medical adhesive smearing device packaged by a glass ampoule tube.

Background

The medical adhesive is used as a new medical product for replacing postoperative suture needles, and provides a brand new method for postoperative tissue repair. The main component of the medical adhesive which is widely used at present is alpha-cyanoacrylate, which has the characteristics of quick curing time and high closing strength. Most of the packages of the medical adhesives used in the clinical operation are glass ampoule tubes for filling and sealing, so as to prolong the shelf life of the medical adhesive products to the maximum extent.

The glass ampoule tube is adopted to package the medical adhesive product to improve the product performance stability, and meanwhile, the glass ampoule tube also has some problems in the use process of clinical operation. For example, a medical adhesive product sold under the trade name "medical adhesive for white clouds" by Guangzhou medical adhesive Limited company breaks off an ampoule tube directly during use, and a disposable dropper is used for absorbing internal adhesive liquid to coat the internal adhesive liquid on the surface of a wound, so that the method has the advantages of long operation time, difficulty in controlling the adhesive liquid yield, difficulty in ensuring the coating uniformity of the adhesive liquid, poor sealing effect of the wound during operation, and certain potential safety hazard in use due to the fact that broken glass residues of the ampoule tube possibly fall into the adhesive liquid; the other medical adhesive product which is produced and sold by Qiangsheng corporation of America is named as 'Dermabond', so that the using steps of the product are simplified, the device only needs to squeeze the middle part of the applicator to crush the ampoule tube and then directly coat the wound in the using process, the operation method is convenient to use, but in the actual operation process, the ampoule tube is difficult to crush, and the requirement of higher operation manual is met for an operator. This creates uncertainty in the healing of the wound for the surgical patient.
