Drug administration device capable of carrying out accurate quantification for urology department

Abstract

The invention discloses a drug administration device capable of carrying out accurate quantification for the urology department, and relates to the field of drug administration devices. The drug administration device comprises a bottom plate, wherein the top side of the bottom plate is provided with an I-shaped groove; a sliding plate is in sliding installation in the I-shaped groove; one side of the sliding plate is fixedly provided with a rack; the top side of the bottom plate is fixedly provided with a round shaft; the round shaft is in movable sleeving with a toothed disc; and the toothed disc and the rack are meshed. In the drug administration device disclosed by the invention, an injection handle is rotated to drive the toothed disc to rotate, the toothed disc rotates to drive the rack to move, the rack moves to drive the sliding plate to slide along the I-shaped groove, the sliding plate moves, through a preset driving mechanism, a piston horizontally moves, drug liquid is sucked into an injection barrel from a drug storage bottle so as to preliminarily preset a drug administration amount, the drug administration amount can be preset before injection, and therefore, the situation that injection is carried out directly by referring to a drug administration scale to cause that the drug administration amount and a standard drug amount have a deviation so as to be likely to cause that drug administration amount is deficient or exceeds the standard, and therefore a drug treatment effect is not ideal can be avoided.

Description

technical field [0001] The invention relates to the field of drug delivery devices, in particular to a drug delivery device capable of precise dosing for urology. Background technique [0002] Urology is a medical science that specializes in the study of male and female urinary tracts and male reproductive systems. It is mainly subdivided from surgery. Male urinary and reproductive systems are inseparable, while female urinary tracts open at the vulva. Regardless of gender, The urinary tract is closely related to the reproductive tract, and the diseases of the two often affect each other. Urology can be further subdivided into various subspecialties such as urological oncology, urinary tract stones, voiding disorders, pediatric urology, sexual dysfunction, and male infertility. Urology needs to use the drug delivery device for drug treatment during the treatment process.

Problems solved by technology

[0003] When the existing urology drug delivery device is used for drug delivery, the medical personnel usually directly perform manual drug delivery by referring to the drug delivery scale instead of presetting the amount to be administered and then injecting it. It is difficult to accurately control the dosage of the drug, and it is easy to cause deviations between the dosage and the standard dosage, which may lead to insufficient or excessive dosage and unsatisfactory drug treatment effects.
