Gynecology administration device

Abstract

The invention discloses a gynecology administration device. The gynecology administration device comprises a drug pushing tube, an outer sleeve and a drug distributing tube, wherein the drug pushing tube is provided with a drug inlet and outlet hole in the front end face, and a first O-type ring is fixed to the outer side wall of the front end of the drug pushing tube; the outer sleeve is arranged outside the drug pushing tube in a sleeving mode, and a second O-type ring is fixed to the inner side of the front end of the outer sleeve; the drug distributing tube is arranged outside the drug pushing tube in a sleeving mode, the rear end of the drug distributing tube is connected with the outer sleeve in a sealed mode, administration holes are formed in the bottom and the side wall of the drug distributing tube, a communicating groove is formed in the inner tube wall of the drug distributing tube, and when the front end of the drug pushing tube abuts against a limiting protrusion, interlayer spaces before and after the first O-type ring are communicated. The administration device discharges a drug through the multiple holes, administrates the drug evenly, is large in acting surface, prevents the drug from accumulating locally, and ensures that the drug fast takes effect on the focus portion in time, and therefore the use efficiency and the treatment effect of the drug are improved; the drug distributing tube is disposable, so that the gynecology administration device is safe and sanitary, the drug pushing tube and the outer sleeve are convenient to clean and can be recycled, and therefore the cost of treating gynecological disease is reduced; excessive drug residue can be avoided, drug waste is reduced, and the gynecology administration device can be operated coherently, smoothly and easily.

Description

technical field [0001] The invention relates to a medical device, in particular to a gynecological drug delivery device. Background technique [0002] In gynecological clinics, vaginal medication is the most commonly used and effective means to treat vaginal inflammation. It uses a drug delivery device to directly send external drugs into the lesion to achieve the purpose of treatment. At present, drug delivery devices suitable for gynecological external medicines such as liquid medicines, gels, and ointments are generally composed of drug distribution tubes, pistons, and push rods. There are many deficiencies in clinical use of drug delivery devices with this structure, such as : It mostly discharges the drug through a liquid outlet hole at the front end. Although the drug can be delivered to the deep vagina, it is easy to accumulate locally, the drug distribution is uneven, and it cannot act on large-scale lesions quickly and effectively, thereby reducing the amount of dru...

AI Technical Summary

Problems solved by technology

But the deficiency that it exists is: firstly, when the piston advances in the drug storage barrel, the medicine can only be discharged from the administration hole positioned at the front side of the piston, thus causing more before administration and less after administration. Can not give full play to the deficiencies of the drug effect; secondly, because the drug needs to be stored in the drug storage tube in advance, and the side wall of the drug storage tube is evenly distributed with a plurality of administration holes, the liquid drug is easy to leak to the outside before the administration operation , causing drug waste

However, its disadvantages are that the drug distribution tube discharges the drug through the drug delivery hole through the air pressure provided by the tube body and the piston. First, because the drug distribution tube adopts a porous structure, it cannot ensure that the drug is evenly discharged from the drug delivery hole. It is difficult to achieve the expected purpose of uniform dosing; secondly, the air pressure provided by the piston and the tube body for the drug distribution tube is easy to leak out from some drug delivery holes in advance, resulting in the remaining medicine cannot be smoothly discharged from the drug distribution tube, eventually causing Part of the drug remains in the drug distribution tube and cannot be used, resulting in drug waste
