Description

Medicine feeder for vagina

Technical Field

The invention relates to the field of medical machinery, in particular to a vaginal medicine feeder.

Background

When aiming at female endophytic system diseases, oral administration is only a means with low efficiency and high toxicity, and because of the characteristics of multiple and easy repetition of gynecological diseases, the medicine is delivered into the vagina to directly act on the focus part, so that the medicine has better curative effect. The existing gynecological disease medicines, whether powder capsules, liquid capsules or tablets, are inconvenient to operate when the medicines are completely delivered into focus parts, although various lotions and suppositories for treating gynecological vaginal and cervical diseases exist clinically, the lotions can only act on body surfaces and vaginal orifices, the suppositories have the defects of self administration, insufficient depth of medicine delivered by hands, foreign body sensation, easy falling, unsatisfactory medicine disintegration and absorption and the like, and other bacterial pollution is easily caused to influence the treatment effect. The treatment effect is not ideal due to the limitation of the administration mode. The therapeutic means with ideal effect mainly acts the therapeutic medicine on the focus part directly, absorbs the therapeutic medicine into blood directly from mucosa and repairs the pathological wound surface, such as treating cervical erosion, cervical cancer and the like. Meanwhile, due to the physiological characteristics of women, except for the factors of menstruation, fertility and the like, the urethra is short and straight, the pudendum is warm and moist, and the women are very easy to be infected by various pathogenic bacteria. 7-10 cm from the vulva to the cervical orifice and 10-13 cm from the vulva to the fornix vaginalis, and the disease part is hidden deeply, so that the direct administration is inconvenient.

At present, the vaginal drug delivery is developed from the original traditional vaginal drug delivery method to the present, and a mode of pushing by fingers can be avoided, so that the subjective psychological conflict caused by the drug delivery mode of the drug delivery mode is avoided, and the problem that the drug cannot be accurately delivered to a treatment position due to factors such as the length of the fingers and the like is effectively prevented, so that the treatment effect is influenced is solved. In addition, although the disposable finger stall can be used in the finger medicine delivery mode, the medicine pollution is easily caused by slight attention, and the vaginal infection is indirectly caused.

Chinese patent (publication No. CN201008700) discloses a disposable vaginal medicine feeder, which comprises a medicine feeding cylinder and a push rod reciprocating in the medicine feeding cylinder, and is characterized in that: the end part of the push rod is provided with an ejector rod, and the end of the cylinder cap of the medicine feeding cylinder is provided with a cavity which is matched with the ejector rod and is used for placing medicines. The device overcomes the problem that the vagina medicine feeder can not push solid medicines, provides a disposable vagina medicine feeder, avoids the defect of feeding medicines by hands, and has accurate medicine feeding position, cleanness and sanitation.

However, the device still cannot solve the problem of liquid delivery, and the liquid delivery has good effect on treating cervical related gynecological diseases.

Patent No. CN209173200U provides a medicine feeder for vagina, and the device includes a pipe fitting the left end cooperation of pipe fitting has first spherical head and second spherical head, first spherical head and second spherical head all have a cock portion, the cock portion insert in the pipe fitting to form sealedly after laminating between with the pipe fitting inner wall, be provided with a plurality of extrusion holes on the spherical face of first spherical head, the cock portion position department of second spherical head is provided with a fluting, be provided with the first fluting that should the fluting in the outer wall department of pipe fitting, the slotted inboard spot welding is fixed with an elastic slice, the slice is arc, be provided with a movable stopper in the inside of pipe fitting, the movable stopper insert to in the cock portion after moving to the left side, the movable stopper acts on the slice, and will the slice is ejecting to this slotted outside, the movable plug is connected with an action rod, and the right end of the action rod extends to the outside of the pipe fitting. The device is in practical application, can be ejecting with the medicine of putting in the fluting through the thin slice, ejecting back medicine bonds in vaginal inner wall department, then pull out the pipe fitting can, it is comparatively convenient to operate, avoid the condition of sending medicine many times repeatedly, the device can also carry liquid medicine simultaneously, only need with first spherical head insert can, accomodate liquid medicine through the pipe fitting, liquid medicine is extruded to rethread piston, the structure of device is comparatively simple, it is comparatively convenient to operate, and is suitable for being generalized to use.

The delivery of liquid and solid medicines through the medicine delivery device avoids the psychological discomfort of patients and greatly relieves the physiological discomfort of the vaginas of the patients, but the symptoms appearing in the treatment process can be treated by combining a plurality of medicines, the above patents can only carry out single medicine delivery, and the repeated pushing of the medicines at the same time increases the discomfort of the patients and the possibility of vaginal injury.
