Duplex mixed syringe with double spray heads

Technical Field

The utility model relates to the technical field of medical equipment, more specifically relates to a duplex mixed syringe of dual spray head.

Background

Currently, as described in chinese patent CN208823454U, although two different injectors are used to deliver two different gelling components, the two gelling components share one nozzle, that is, the two gelling components are mixed in the nozzle and then ejected from the nozzle; therefore, once the sprayer is stopped when in use, the mixed liquid at the sprayer can react to form colloid, so that the sprayer is blocked and cannot be used continuously, and the sprayer must be stopped for replacement or cleaned for continuous use.

In order to solve the above problems, a conventional solution is to increase the gelling speed of the liquid medicine, so that the liquid medicine can be continuously used when the liquid mixed by the nozzle is not fully gelled. However, in order to meet the use requirements of biological glue products, the products are generally required to be quickly gelatinized after being mixed, the colloid is required to be gelatinized within about 10s, otherwise, the specified part cannot be accurately coated, and liquid which does not undergo gelatinization reaction flows away. The gelatinizing speed has the requirement of using the product, and the gelatinizing time cannot be excessively prolonged, so that a very obvious contradiction exists between the condition that the spray head is blocked after the gelatinizing components in the spray head are mixed and the product is rapidly gelatinized.
