Tube wall on be evenly distributed with dosing holes, the outer surface of delivery tube is set with gum cover, and the length of the gum cover is less than delivery tube, gives
The rear end of pencil is fixedly installed with plug；Around multiple flexible fins are distributed on the drug delivery axis, the rear end of drug delivery axis is fixed to pacify
Equipped with handle；.
The flexible fins are rectangular sheet structures, and the width of flexible fins is greater than the outer wall and administration inside pipe wall of drug delivery axis
The distance between, flexible fins are longitudinally connected on the outer wall of drug delivery axis in the inner side edge of length direction, the outside of flexible fins
While being resisted against on the inner wall of delivery tube.
The fin is spirally distributed on drug delivery axis.
Washer of the rear end of the drug delivery axis with diameter not less than the outer diameter of delivery tube.
The vaginal administration device is compact-sized, easy to use due to the above structure, and application portion can be accurately positioned
Position, is administered uniform no pain, is particularly suitable for conveying on sticky ointment and is coated in affected part.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the structural schematic diagram that fin is spirally distributed on drug delivery axis.
Specific embodiment
As shown in Figure 1, a kind of vaginal administration device described in the utility model includes the delivery tube 1 of circular tube shaped and is mounted on administration
Drug delivery axis 2 in 1 inner cavity of pipe, the diameter of drug delivery axis 2 are slightly less than the internal diameter of delivery tube 1, have certain gap between the two.It gives
The front end of pencil 1 is hemispheric closed end 11, in order to can smoothly be inserted into vagina when medication；It opens the rear end of delivery tube 1
Mouth is made for inserting drug delivery axis 2, the delivery tube 1 of materials such as stainless steel or plastics, on the tube wall of delivery tube 1 uniformly
Be distributed with multiple dosing holes 3, dosing holes 3 run through the tube wall of delivery tube 1, for by the drug in 1 inner cavity of delivery tube dredge to
On the outer wall of pencil 1, furthermore it is also possible to front end dosing holes 31 be arranged on the tube wall of the closed end 11 of 1 front end of delivery tube, before this
Dosing holes 31 are held to run through the tube wall of closed end 11, for the drug in 1 inner cavity of delivery tube to be dredged to the front end of delivery tube 1.
The outer surface of delivery tube 1 is set with gum cover 7, and the gum cover 7 is using materials systems such as the biggish silica gel of elasticity, rubber
At the length of gum cover 7 is less than delivery tube 1, and gum cover 7 can be administered with enclosure portion dosing holes 3 for targetedly open portion
Hole 3, positioning application position.The rear end of delivery tube 1 is fixedly installed with plug 5, and the plug 5 is made of rubber or silica gel material
Cone, plug 5 is blocked in the outside of vagina after delivery tube 1 is inserted into vagina when use, can prevent 1 outer wall of delivery tube
On drug skid off vagina；Around being distributed multiple flexible fins 4 on the drug delivery axis 2, the quantity of flexible fins 4 can be 3,
It four or 5, is uniformly distributed around drug delivery axis 2；The rear end of drug delivery axis 2 is fixedly installed with handle 6, and handle 6, which uses, facilitates hand
The shape held can drive drug delivery axis 2 to rotate with hand rotational handle 6.
The flexible fins 4 are rectangular sheet structures, are made of silica gel or softer plastics, the width of flexible fins 4
Degree is greater than the distance between outer wall and 1 inner wall of delivery tube of drug delivery axis 2, and flexible fins 4 longitudinally connect in the inner side edge of length direction
It connects on the outer wall of drug delivery axis 2, the outer side edges of flexible fins 4 are resisted against on the inner wall of delivery tube 1.As shown in Fig. 2, due to flexibility
The width of fin 4 is greater than the gap between 1 inner wall of drug delivery axis 2 and delivery tube, and soft flexible fins 4 are convexly curved, when sending
When medicine axis 2 is rotated along the arc-shaped bend direction of flexible fins 4, the inswept administration at a slant of the outer ledge of flexible fins 4
The inner wall of pipe 1, so that it may the ointment being adhered on 1 inner wall of delivery tube be got into dosing holes 3, and ointment is gradually passed through into dosing holes
3 are expressed on the outer wall of delivery tube 1.
In use, first according to the position of the position for the illness observed in advance adjustment gum cover 7, if disease sites are deeper,
Gum cover 7 is adjusted backward then, the dosing holes 3 of rear end are closed, keeps the dosing holes 3 of front end for smearing ointment to deeper portion
Position；If disease sites are wide, when needing large area to smear, gum cover 7 can also be removed, open whole dosing holes 3；
If disease sites are shallower, gum cover 7 can be adjusted forward, ointment is made to be applied to shallower position；Adjust gum cover 7 with
Afterwards, it extracts drug delivery axis 2 out, the biggish ointment of viscosity is put into delivery tube 1, then drug delivery axis 2 is injected into delivery tube 1, the quantity of ointment
Drug delivery axis 2 of being subject to does not overflow after injecting delivery tube 1；After drug delivery axis 2 can also be extracted out, drug delivery axis 2 is directly inserted into ointment
In bottle, makes to be stained in flexible fins 4 and inject delivery tube 1 again after ointment.Finally delivery tube 1 is inserted into together with drug delivery axis 2
In vagina, one is held by that plug 5 is another to be held by handle 6, and handle 6 is rotated along the direction of flexible fins 4, while lightly left
Dynamic plug 5 of turning right is that delivery tube 1 carrys out back rotation, and with the rotation of drug delivery axis 2 and flexible fins 4, ointment is squeezed out across dosing holes 3
Onto the outer wall of delivery tube 1, and as gently swinging for delivery tube 1 is applied on the inner wall of vagina.
In addition, as a further improvement of the utility model, as shown in figure 3, the flexible fins 4 are on drug delivery axis 2
Spiral distribution.The flexible fins 4 of spiral distribution while ointment is got into dosing holes 3 can also by extra ointment by
Gradually to being pushed forward, the front end that the front end dosing holes 31 on closed end 11 are expressed into delivery tube 1 is eventually passed through.Certainly, if you do not need to
Front end administration, the direction of flexible fins 4 can also be parallel with the axis of drug delivery axis 2, when flexible fins 4 squeeze ointment at this time
It can be only expressed in dosing holes 3, without pushing forward.
As another improvement of the utility model, the rear end of the drug delivery axis 2 is outer not less than delivery tube 1 with diameter
The washer 21 of diameter, washer 21 are sleeved on drug delivery axis 2, positioned at the front of handle 6.Washer 21, which uses, certain thickness rubber material
Material is made, and drug delivery axis 2 injects after delivery tube 1, and washer 21 is got lodged on the rear port of delivery tube 1, and playing prevents ointment from rear end
The effect of mouth outflow.
