Description
Technical field
The present invention relates to technical field of medical instruments, be specifically related to a kind of medicament feeder for cervix uteri part.
Background technology
Cervicitis, vaginitis, ulcer of cervix are woman uterus position commonly encountered diseases, and its sickness rate is higher.Patient's pruritus of morbidity unbearably, leucorrhoea grow in quantity, flavor be smelly, and easy infection, easily recurrence, easily rotten to the corn hemorrhage bring bigger misery to patient, particularly with high-risk HPV persistent viral infection cervical lesions patient, if treatment does not in time easily cause cervical cancer etc.Conventional treatments at the uterus neck pathological changes commonly used at present has two kinds, a kind of is to use the liquid medicine lavation, another kind is that tablet medicine, suppository medicine, capsule, pastille antibacterial film etc. are filled in the vagina diseased region, when it is filled in, general nothing is suitable for can mate apparatus, push with finger mostly, its shortcoming is:
1. because disease sites at the cervix uteri place, must pass through vagina when medicine is sent into, and the length of general vagina is at 7～12 centimetres, words with finger are difficult to medicine is delivered to diseased region exactly, medicine can not effectively guarantee with contacting of diseased region, deviates from easily, affects the treatment.
2. as not using disposable sterilized apparatus, bring into vagina such as antibacterial, mycete easily, intravaginal pathogenic bacteria also can be taken out of thereupon, causes cross infection easily.
3. because factors such as finger skin is rough, fingernail is sharp-pointed, vagina drying can cause pain in various degree when medicine is filled in.
In recent years, along with going deep into of macromolecular material research, groups of people begin to attempt with the moulding pastille film of fitting with the cervix uteri physiological structure of making of macromolecular material, expection pastille film can fit tightly with uterus neck, and keep the long period, substantially do not influence work and life during applying ointment or plaster, medicine is sustainable release also, is expected to obtain better therapeutic effect.But, how to make the pastille film by vaginal dilator, through per vaginam arriving uterus neck accurately, and in this process, do not damage the mucosa of vagina inboard, also there is more difficulty.
Existing uterus neck administration device only can single conveying liquid medicine or solid preparation, all can not be used for the administration of medicine film cervix uteri.
Summary of the invention
The objective of the invention is: a kind of medicament feeder for cervix uteri part is provided, be disposable medical apparatus and instruments, not only flexible, safe and sanitary, no pain, and avoided cross infection, substantially do not block sight line during use, can accurately the pastille film be put into the cervical lesions position.
The present invention adopts following technical scheme to realize goal of the invention: a kind of medicament feeder for cervix uteri part is provided, and it comprises sleeve, interior push jack and push rod, and described push rod one end places in the sleeve, and is connected with interior push jack one end; Described sleeve front portion is that the rubber-like of softness is uncovered, and described uncovered front end is connected with the described interior push jack other end.
In one embodiment, the thin curved face type of uncovered preferred circle of described barrel forward end is uncovered.
In certain embodiments, material with certain elasticity and flexibility such as the uncovered employing silica gel of described barrel forward end, rubber is made.Part and push rod and the interior push jack of sleeve except front end is uncovered is made of plastics.
When push jack was downward in the push rod pulling, interior push jack drove the anterior soft uncovered edge of sleeve pipe and bends inwardly and downwardly, and makes the sleeve pipe front portion constitute matrix together with interior push jack, the gel of medicine film, medicine or suppository etc. is placed in one can run off at this moment.Because sending into the device top is rendered as circular arc, also can not cause damage when sending into uterus neck.Enter the medicine-feeding part rear push-rod and promote interior push jack upwards, medicine can be released and stay medicine-feeding part.
To be interior push jack closely link to each other preferred 5 with the uncovered front end of sleeve by two or more hard sheets in the further improvement of technical solution of the present invention; The connecting portion of described hard sheet and interior push jack can fold.The size of push jack in can obviously reducing like this, when push jack was downward in the push rod pulling, the connecting portion of hard sheet and interior push jack can fold, and made the sleeve pipe front portion constitute darker matrix together with interior push jack, can hold more medicine.In addition, because interior push jack size reduces, can make medicine send into device and be contracted to more minor diameter, whole circular arc Du Genggao is difficult for blocking sight line when sending into uterus neck, be convenient to medicine is accurately delivered to the affected part.Described hard sheet can be made of plastics.
It is that inner push-rod is provided with more than one positioner that technical solution of the present invention is further improved, and when push rod pulls down to certain position, positioner just in time is limited to the opening part of sleeve bottom, and fixedly push rod makes it upwards not slide.When according to certain distance positioner being set at push rod, push rod rests on diverse location, and then the sleeve pipe front end is different with the volume of the matrix container of interior push jack formation, can satisfy the administration needs of various dose.Described positioner can be banking stop, spacing hoodle or spacing button, and described spacing button can be circle, triangle, square etc.
Medicament feeder for cervix uteri part of the present invention is simple in structure, easy to use, can be used for the uterus neck administration of medicine film and solid pharmaceutical preparation, can accurately medicine film or solid pharmaceutical preparation be put into the cervical lesions position, and can fit tightly with cervix uteri, improved the absorption of medicine.
