Medicine proportioning injector for pharmacy department

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to medicine ratio syringe for pharmacy department.

Background

Various studies have indicated that the accuracy of dose delivery is affected by several factors, including: the manner of injection, the inability of the healthcare practitioner to accurately interpret and control the movement of the plunger, and the associated depletion of medication during the initial steps of purging air from the syringe prior to the dispensing step, have indicated that the total amount of medication delivered may vary significantly as the healthcare practitioner chooses to depress the plunger from 10 ml to 5 ml or from 5 ml to 0 ml during the treatment to deliver a 5 ml dose. In addition, because the plunger movement limit is not fixed, some practitioners may deliver an excess dose to the patient because of the mechanical compliance between the stopper and the syringe barrel, depressing the syringe through the natural movement limit. For example, with a particular syringe barrel diameter, a practitioner may erroneously deliver up to 20% of the excess dose by depressing the plunger through a natural 0 ml stop, an error that may be magnified by the small dose volume requirements of a particular treatment. Because the total amount of medicament and the associated plunger travel distance are small, it is difficult for a practitioner to estimate the total amount of medication chamber filling and control the total amount of therapeutic injections administered to a patient. Such imprecise dosing may lead to substantial safety risks including side effects therein, increased stress in the target area, and altering (decreasing) the effectiveness of the drug.

Therefore, a drug proportioning syringe for pharmacy is needed, and a drug proportioning syringe for pharmacy is proposed to solve the above problems.
