The push type vaginal drug administration device is easy to control in pushing and is convenient to use. After the drug and a cotton swab are fed into the body, the cotton swab expands to form a closed environment so as to completely release the drug.
Description
Technical field
This utility model belongs to medical instruments field, is specially a kind of medium that pushes and enters the doser in body.
Background technology
In gynecopathy therapeutic process, vagina administration is Therapeutic Method the most effectively, for example, in prior art, have by interior ejector sleeve and shift the tampon with medicine in outer tube onto vagina depths to reach the object (patent 99241139 " Deop medicinal vaginal pessary ") for the treatment of disease.Patent CN201591909 also discloses a kind of Deop medicinal vaginal pessary, and it comprises trocar sheath and inner sleeve, and when inner sleeve advances in trocar sheath completely, stype and swab stick just can slip into appropriate location.
In prior art, because internal and external casing is smooth surface, therefore there is the caducous defect of appearance.Some medicaments are liquid, and when placement, medicament liquid contacts together and puts into swab stick, but medicinal swab stick is met expansion of liquids, and the bad assurance of dynamics that inner sleeve pushes, is difficult to promote medicament and swab stick is advanced, and brings difficulty to administration.
Summary of the invention
For the deficiencies in the prior art part, the purpose of this utility model is to propose a kind of drive-in vaginal administration device.
For realizing this utility model object technical scheme be:
A kind of drive-in vaginal administration device, is made up of pipe cap, trocar sheath, propulsion tube;
Described trocar sheath is the hollow circular tube of upper and lower opening; Outer sleeve inner wall is provided with the inside annular projection of a circle;
Described propulsion tube is cylindrical shape, and the diameter at propulsion tube top is less than propulsion tube caliber, and described propulsion tube top is evenly arranged with 3-6 sheet blade around, and the root of described blade is connected with described propulsion tube, and described blade surrounds annulus; There is outside projection the end of blade, and the external diameter of described projection is greater than the internal diameter of described trocar sheath.Because inner sleeve is provided with blade, this blade outwardly convex, make blade projection diameter be greater than inner sleeve internal diameter, make to produce and rub between blade and outer sleeve inner wall, can prevent that propulsion tube from coming off, in addition, blade projection convexes to form hook with inner tubal wall one circle described in power 2, also plays and slows down the effect coming off.
Described pipe cap is the dome pipe of top closure, and described pipe cap and trocar sheath closely cooperate.
Preferably, the bottom expansion of described propulsion tube, the part of expansion has wire casing.In swab stick is placed on trocar sheath, the stay cord that swab stick connects is drawn from the line hole of propulsion tube, is entangled in wire casing, connects because of carelessness stay cord and together push in body while avoiding user to push, when taking out swab stick, just bothers very much.
Preferably, described propulsion tube top is evenly arranged with 4 blades around.
Preferably, inner sleeve top is provided with the groove that holds medicine (as capsule)
Propulsion tube top can be sealed completely, also can have at propulsion tube top the line hole by stay cord.
When this utility model administrator uses, remove pipe cap, medicament and swab stick are placed in trocar sheath, the stay cord that swab stick connects can be drawn from the line hole of propulsion tube, be placed in propulsion tube wire casing, trocar sheath, to firmly needing the position of administration, is advanced to propulsion tube, medicament and swab stick are entered in body, then abandon trocar sheath and propulsion tube.
Drive-in administrator of the present utility model can adopt polymers manufacturing, also can adopt the composite manufacture of Organic substance or inorganic matter combination, for example, a kind of or its complex in polyethylene, polrvinyl chloride, polystyrene, politef, silica gel.
The beneficial effects of the utility model are:
The drive-in vaginal administration device the utility model proposes, is easy to when propelling movement control, easy to use.After medicament and swab stick are sent in body, swab stick expands, and forms the environment of sealing, and medicament is fully discharged.Administration time completes, and holds stay cord, pull-out swab stick.
Brief description of the drawings
Fig. 1 is the drive-in vaginal administration device the utility model proposes, and is placed with the structure chart of medicament, swab stick, pipe cap.
Fig. 2 is propulsion tube structure chart.
Fig. 3 is propulsion tube top view.
Fig. 4 is propulsion tube upward view.
Fig. 5 is outer sleeve structure figure.
In figure, 1 is pipe cap, and 2 is propulsion tube, and 3 is trocar sheath, 301 internal projection that are trocar sheath, and 4 is stay cord, and 5 is blade, and 501 is blade projection, and 6 is propulsion tube top, and 7 is the expansion of propulsion tube bottom, and 8 is wire casing, and 9 is medicament, 10 is swab stick.
Detailed description of the invention
Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
Embodiment 1:
Drive-in vaginal administration device, is made up of pipe cap 1, trocar sheath 3, propulsion tube 2; The hollow circular tube that trocar sheath 3 is upper and lower opening.
Referring to Fig. 2,3,4, propulsion tube 2 is cylindrical shape, propulsion tube top 6 has the line hole by stay cord, the diameter at propulsion tube top 6 is less than propulsion tube caliber, propulsion tube top 6 is evenly arranged with four blades 5 around, and its root and propulsion tube 2 link together, and blade 5 surrounds annulus, there is blade projection 501 end, and the external diameter of naturalness lower blade projection 501 is greater than the internal diameter of described trocar sheath; 7 expansions of propulsion tube bottom, the part of expansion has wire casing 8.
The dome pipe that pipe cap 1 is top closure.
The inwall of trocar sheath 3 is provided with internal projection 301(Fig. 5 of an inside circle trocar sheath), when drug packaging, pipe cap 1 closely cooperates with trocar sheath 3, and medicament 9 and swab stick 10 are placed in trocar sheath, and propulsion tube is inserted in trocar sheath (as Fig. 1).Stay cord is drawn from propulsion tube bottom 7, is placed on 8 li of wire casings.When administration, take off pipe cap, medicament and swab stick are placed in trocar sheath, swab stick connect stay cord draw from the line hole of propulsion tube, be placed in propulsion tube wire casing, by trocar sheath to firmly needing the position of administration, advance propulsion tube, medicament and swab stick are entered in body, then abandon trocar sheath and propulsion tube.Because inner sleeve is provided with blade, this blade is outwardly-bent, make blade projection 501 external diameters be greater than inner sleeve internal diameter, between blade and outer sleeve inner wall, produce friction, can prevent that propulsion tube from coming off, in addition, carefully see, the outside of blade also has some projections or as figure " hook ", blade projection 501 forms " hook " with the internal projection 301 of trocar sheath, also plays and slows down the effect coming off.
Above embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of this utility model design spirit; various modification and improvement that the common engineers and technicians in this area make technical scheme of the present invention, all should fall in the definite protection domain of claims of the present utility model.
