Abstract
The utility model relates to a cavitary drug feeder, which belongs to the field of the medical instruments and can reduce the unpleasant effect to the patient. The drug feeder comprises: a spherical crown shaped tube at one end of a drug outlet and a cap which covers the outside of the drug outlet. The drug outlet of the drug feeder is in the shape of spherical crown, which highly coincides with the cavitary physiological structure and cannot cause the discomfort of the patient. The spherical crown shaped structure can prevent the liquid medicine flowing back. The spherical crown shaped drug outlet is covered with the cap, thus the drug outlet is free from the pollution of the harmful bacteria and the dust in the air. The cap cover is well closed to ensure the liquid medicine which cannot flow out when the drug feeder bears some pressures.
Description
Technical field
The present invention relates to the medical apparatus field, particularly relate to a kind of administrator.
Background technology
In clinical treatment, tract local patholoic change or discomfort in most cases do not need through oral drug therapy, but adopt topical to get final product.Tract is not a body surface, must be that administrator can be sent to agents area with medicine by utensil, the physiological structure of tract determined administrator must possess health, smooth in appearance, with characteristics such as tract goodness of fit height.
In the prior art, common administrator has three kinds.
A kind of is injector, adopts the principle of injecting of syringe.Injector generally is made of front end cap, powder charge cylinder, piston and push rod, back plug four parts, and it is cylindric that integral body is, the external diameter basically identical, front end is opened aperture, the cover piston rear end in, administrator stretched into tract after, by push rod promotion piston, medicine is extruded.The injector wall is harder, and the cylindric body front end of external diameter unanimity is opened aperture, and this kind is provided with and easily causes patient's discomfort, and might cause that medicinal liquid flows backwards during administration.
A kind of is that irrigator is made up of syringe pipe and compressible container, by being threaded.General in addition equipped drug package.During use, pour medicine into compressible container, repress is gone into agents area.Flushing part paracone hind wing, identical bad with the human physiological structure, easily cause discomfort, the syringe pipe that touches mucosa in the tract is vulnerable to airborne pathogenic bacteria and contamination by dust, and the administration process is also more loaded down with trivial details.
A kind of is squeezer, adopts soft tubular structure, and two ends are flat, and are front fine and rear thick, middle reducing.Front end is the spherical crown shape, links to each other with front end flat position.Because flexible pipe has thixotropy, push the rear end gently with finger, medicine can be extruded.Squeezer is made as one-shot forming, is a complete integral body, and two ends all seal, and during medication, front end spherical crown shape partly must be fractureed, and exposes aperture, medicine can be extruded.Owing to need before the administration to fracture with the spherical crown binding site front end is flat, can not guarantee that the place of fractureing is very smooth, the issuable burr of fracture place can cause discomfort to agents area.
Summary of the invention
In view of this, the invention provides a kind of cavity/canal drug administration device, reduce the sense of discomfort that the patient is caused.
For solving the foregoing invention purpose, this utility model provides a kind of cavity/canal drug administration device, comprising:
One end of medicine outlet is the coronal body of ball;
Cover the cap of described medicine outlet outside.
Preferably have, in the said apparatus, described cap inside is provided with the little plug corresponding with medicine outlet.
Preferably have, in the said apparatus, described cap is for sealing film.
Preferably have, in the said apparatus, described cap is the coronal end of ball with described administrator and adopts cassette to be connected.
Preferably have, in the said apparatus, described cap is the coronal end employing of ball with described administrator and is threaded.
Preferably have, in the said apparatus, described body is a hose body.
Preferably have, in the said apparatus, described administrator is the coronal end of ball and is connected to an end that is cryptomere by the body transition, and administrator cryptomere position is flat.
Preferably have, in the said apparatus, the volume of the cryptomere of described administrator part equates with the volume of remainder.
Preferably have, in the said apparatus, described administrator is a plastic.
Preferably have, in the said apparatus, described administrator is the plastic-aluminum goods.
Compared with prior art, the present invention has the following advantages: the medicine outlet of administrator is the spherical crown shape, and spherical crown shape structure and tract physiological structure goodness of fit height can not cause patient's discomfort, and spherical crown shape structure can prevent that medicinal liquid from flowing backwards.The coronal medicine outlet of ball is coated with cap outward, can make medicine outlet not be subjected to the pollution of airborne pathogenic bacteria and dust, and cap is built the back guarantees that medicinal liquid can not flow out at administrator after bearing certain pressure.
Description of drawings
Fig. 1 is this utility model embodiment one structural representation;
Fig. 2 is this utility model embodiment two structural representations;
Fig. 3 is this utility model embodiment seven structural representations.
The specific embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Embodiment one, referring to Fig. 1.
This utility model provides a kind of cavity/canal drug administration device, comprising: an end of medicine outlet 2 is the coronal body 1 of ball; Cover the cap 3 of described medicine outlet 2 outsides.
The medicine outlet 2 of administrator is the spherical crown shape, and spherical crown shape structure and tract physiological structure goodness of fit height can not cause patient's discomfort when stretching into medicine outlet 2 ends in the tract, and spherical crown shape structure can prevent that medicinal liquid from flowing backwards.
The coronal medicine outlet of ball 2 is outer to be coated with cap 3, can make medicine outlet 2 not be subjected to the pollution of airborne pathogenic bacteria and dust, and cap 3 is built the back guarantees that medicinal liquid can not flow out at administrator after bearing certain pressure.Adopt cap 3 to cover medicine outlet 2 outsides, can not occur staying burr when squeezer fractures front end and spherical crown portion coupling part and cause the situation appearance of patient's discomfort.Can not cause the administrator distortion after the use, administrator can repeatedly use, and effectively saves cost.
Embodiment two, referring to Fig. 2.
Similar with said apparatus, difference is with it, and cap 3 inside are provided with the little plug 4 corresponding with medicine outlet.
At the cap 3 inner settings little plug 4 corresponding with medicine outlet, when covering cap 3 outside the medicine outlet, little plug 4 coincide with medicine outlet, guarantees the sealing of administrator.Better guarantee that medicine outlet is not subjected to the pollution of airborne pathogenic bacteria and dust, and cap 3 is built the back guarantee that medicinal liquid can not flow out at administrator after bearing certain pressure.
