Description

A kind of administrator

Technical field

This utility model relates to a kind of administrator, particularly relates to a kind of administrator that is applicable to gynecological's cervix uteri and vaginal treatment, belongs to gynecological's administration device.

Background technology

At present, the medicine great majority for the treatment gynaecopathia are ointment formula dosage form or suppository clinically, generally use smearing method; Its ointment formula agent is used very inconvenient, and suppository need be put on disposable finger cot stype is sent in patient's body when administration, because the suppository time is deposited hardening easily after a period of time, makes medicine can't stripping discharge and influence therapeutic effect.Also can bring discomfort simultaneously to the patient.Recently the time clinically for the treatment gynaecopathia, also there is the tubular type of employing administrator to treat, this kind administration device exists the relatively poor easy-to-leak liquid of sealing between pushing ram and the pencil, and pushing ram is pushed into the pencil top and also has gap (pushing away not in place), and squeeze the medicine in the pipe only and cause waste, there is air the pencil the inside, during the fill medicine, the inside air can not arranged, and causes the medicine the inside bubble to be arranged and influence therapeutic effect.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned defective, and a kind of no leakage is provided |, safe in utilization, can insert vagina and directly push medicine to lesions position, operate quite easyly, avoided the administrator of cross infection.

Technical solutions of the utility model: a kind of administrator, comprise pencil, pushing ram and piston, piston bush is on the piston union joint of pushing ram, the pencil head has a dosing holes, it is characterized in that described this administrator is provided with the pencil helmet, this pencil helmet inner chamber head center be provided with the pencil head on dosing holes match seal plunger, it seals plunger and the pencil helmet is an overall structure, the pencil helmet is sleeved on the pencil head, its dosing holes with seal that the closely knit plug of plunger is stifled to be cooperated, promptly seal in the plunger insertion dosing holes.The pencil rear end has pushing ram to insert mouth, and the cross section of pushing ram is a cross; Pushing ram inserts in the pencil.

Described pushing ram front end is the piston union joint, and the rear end is push pedal, and the piston union joint is the bulb shape.Described piston center is useful on the blind hole that connects the piston union joint, and promptly piston bush is on the piston union joint of pushing ram.Seal that the closely knit plug of plunger is stifled to be cooperated in piston and pencil, pencil and the pencil helmet.Make it can leakage, avoid cross infection.Pencil length 80 ~ 150mm, the cross section of pushing ram are cross; Piston can be pushed into the position of close medicine, the gas of leaving a blank in having reduced is avoided air pollution, and simultaneously, the pencil internal pressure can not raise, in order to avoid front end when opening, overflows medicine.This administrator is a kind of administrator that is used for the treatment of cervix uteri and vagina that the structural principle according to syringe designs.Simultaneously, this administrator also can be used for rectally.

This utility model is simple in structure, and is easy to manufacture, safe in utilization, convenient, no leakage, and it can make medicine patient's internal lesions place that go directly, directly to its use medicine, operates quite easyly, has avoided cross infection.

The specific embodiment

Referring to above-mentioned accompanying drawing, a kind of administrator, comprise pencil 1, pushing ram 2 and piston 3, piston 3 is enclosed within on the piston union joint 21 of pushing ram, pencil 1 head has a dosing holes 11, it is characterized in that described this administrator is provided with pencil helmet 4, these pencil helmet 4 inner chamber head center be provided with pencil 1 head on dosing holes 11 match seal plunger 41, it seals plunger 41 and is overall structure with pencil helmet 4, pencil helmet 4 is sleeved on pencil 1 head, seal that plunger 41 closely knit plugs are stifled to be cooperated in its dosing holes 11 and the pencil helmet 4, pencil 1 rear end has pushing ram to insert mouthful, in the pushing ram 2 insertion pencils 1.

Described pushing ram 2 front ends are piston union joint 21, and the rear end is push pedal, and piston union joint 21 is the bulb shape.Described piston 3 centers are useful on the blind hole that connects piston union joint 21, and promptly piston 3 is enclosed within on the piston union joint 21 of pushing ram.Piston 3 and pencil 1, dosing holes 11 on the pencil 1 and 4 interior the sealing 41 closely knit cooperations of plunger of pencil helmet.Pencil 1 length 130mm.

During the needs of patients treatment, as long as in its pencil behind the fill medicine, pushing ram inserted in the pencil get final product, during use, pull up pencil helmet 4, seal and stop up 41 and be pulled out (seal stop up 41 be one with pencil helmet 4) from dosing holes 11 simultaneously, pencil is inserted vagina, use pushing ram 2 that medicine is released from dosing holes 11 then and get final product.
