Description

Medical applicator

Technical Field

The invention relates to the field of medical instruments, in particular to a medical applicator.

Background

According to statistics, about 4300 ten thousand of surgical operations in 2017 in China still increase by about 8% every year through trend analysis in recent years. In surgical operation, suturing and pricking are two most basic operations. However, this method is not only tedious, laborious and time-consuming, but also easily causes new injuries and bleeding, which causes more pain to the patient. Doctors also feel stranded for large-area oozing blood where bleeding points cannot be found, and the advent of medical adhesives having rapid hemostatic, occlusive, and adhesive effects provides a solution to the above problems.

The prior clinical medical adhesive package mostly adopts a glass ampoule bottle for filling and sealing to improve the performance stability of the product so as to furthest prolong the shelf life of the medical adhesive product. At present, the glass ampoule bottle is combined with a Pasteur straw for use in a clinical traditional mode, the ampoule bottle is directly broken off in the using process, the Pasteur straw is used for sucking the adhesive and coating the adhesive on a wound, the method is inconvenient to operate, long in using time and difficult to control the coating uniformity, and meanwhile, the broken glass ampoule bottle can fall into the adhesive and has certain potential safety hazard. With the development of science and technology, the glass tube is placed in a silica gel or soft plastic smearing bottle in a newly emerging package in the market at present, the smearing bottle is pinched by hands during use, namely after the glass tube is pinched, the medical adhesive flows into the smearing bottle and flows out from a port of the smearing bottle to be smeared at the position of a skin wound. This method has a high demand on the operator's technique, and the glass tube needs to be continuously squeezed by hand, and the glass tube may puncture the application bottle, and there is a risk that the broken glass bottle punctures fingers.
