Description

Medicine applying device for rectum

Affiliated technical field the present invention relates to a kind of medicine applying device for rectum, can be widely used in the medical device industry.

In the existing technology of background technology, there is not special medicine applying device for rectum, clinically, often need to adopt the medication of medicine being sent into rectum by anus, usually after the sealing part that will contain the bottleneck front end of medicine is cut off, elongated bottleneck is as the pipeline of drug delivery, insert anus and extrude medicinal liquid, because the bottleneck clip is comparatively sharp, during insertion, can damage rectal mucosa, the little air that bottleneck has also can at first be squeezed into rectum, side effect is bigger, and does not indicate scale on it, can not control instant dosage at any time.

Summary of the invention the object of the present invention is to provide a kind of simple in structure, easy to use, can not damage rectal mucosa, be convenient to observe at any time the medicine applying device for rectum of inner dose.

In order to achieve the above object, medicine applying device for rectum of the present invention comprises insertion tube, and drug pushing device is installed in the flexible catheter between insertion tube and the drug pushing device; Said insertion tube, front end are slick hemispherical, and the rear end is an oval baffle plate, and the size of rear end inner chamber should match with the flexible catheter front; Said drug pushing device, by have scale and link to each other with flexible catheter push away pencil, insert the stype that pushes away that has rubber seal that pushes away in the pencil and constitute; Insertion tube, drug pushing device and flexible catheter are made by transparent plastic material.

That medicine applying device for rectum of the present invention, plastic material should have is nontoxic, not flexible, toughness, non-broken up characteristics preferably, has preferably transparency can observe content.Flexible catheter one end tube wall thickening forms joint and engages in order to the jack with the insertion tube rear end, and other end diameter overstriking tube wall thickening formation jack engages in order to the plug with the drug pushing device front end, and no-float can not leakage; Push away stype and place to push away and also should cooperate in the pencil closely, do not leak medicinal liquid.Oneself touch when one of effect of flexible catheter is patient's self-administration less than the medicine that pushes away of drug pushing device and fasten, can't exert oneself, the adjunction flexible catheter can solve it; Two of effect is that insertion tube can be adjusted angle according to the rectum traveling automatically at anal, avoids the gravity of firmly artificial or drug pushing device to stick up the straightening intestinal mucosa.

Medicine applying device for rectum of the present invention, parts are few, and are simple in structure, easy to use, easy to implement.

Medicine applying device for rectum of the present invention is compared with existing administrator, and the insertion tube front end is slick hemispherical, and pipeline is smooth, so that insert anal, can not damage patient's rectal mucosa; The insertion tube rear end is an oval baffle plate, slips into anal fully to prevent insertion tube.

Medicine applying device for rectum of the present invention, insertion tube and drug pushing device are transparent, and pushing away pencil has the scale dosage to indicate, so that observe inner dose at any time, can not bring air into rectum.

In sum, medicine applying device for rectum of the present invention, simple in structure, easy to use, can not damage rectal mucosa, be convenient to observe at any time inner dose.

Description of drawings is done further explanation below in conjunction with accompanying drawing and embodiment to the present invention.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the insertion tube sketch map among Fig. 1;

Fig. 3 pushes away the pencil sketch map among Fig. 1;

Fig. 4 pushes away the stype sketch map among Fig. 1.

The specific embodiment is in Fig. 1～Fig. 4, and medicine applying device for rectum of the present invention comprises insertion tube 1, and drug pushing device 2 is installed in the flexible catheter 3 between insertion tube and the drug pushing device; Said insertion tube 1, front end is slick hemispherical a, and the rear end is an oval baffle plate b, and the size of rear end inner chamber should match with the flexible catheter front; Said drug pushing device 2, by have scale and link to each other with flexible catheter push away pencil 2-1, insert the stype 2-3 that pushes away that has rubber seal 2-2 that pushes away in the pencil and constitute; Insertion tube, drug pushing device and flexible catheter are made by transparent plastic material.

Medicine applying device for rectum of the present invention, can not only be used for constipation patient, also can be used for being reluctant the pediatric patient of oral drugs, if certain medicine can absorb by the per rectum mucosa well, then can be with the liquid dosage form of this kind medicine, send into rectum by medicine applying device for rectum, finish the administration process, avoided because of children's refuse oral drugs by force perfusion choke into the danger of trachea.

Medicine applying device for rectum of the present invention, some medicine can cause gastrointestinal reaction owing to oral administration, or owing to the effect of gastric acid lessens the curative effect, if this medicine can stably absorb by per rectum mucosa, then this kind medicine can be made liquid dosage form and finish the administration process by medicine applying device for rectum, very convenient.The appearance of medicine applying device for rectum will become a kind of route of administration commonly used to the rectally approach that is of little use, and solve the administration inconvenience that multiple factor causes in the clinical position.

Claims

1. a medicine applying device for rectum is characterized in that, comprises insertion tube, and drug pushing device is installed in the flexible catheter between insertion tube and the drug pushing device; Said insertion tube, front end are slick hemispherical, and the rear end is an oval baffle plate, and the size of rear end inner chamber should match with the flexible catheter front; Said drug pushing device, by have scale and link to each other with flexible catheter push away pencil, insert the stype that pushes away that has rubber seal that pushes away in the pencil and constitute; Insertion tube, drug pushing device and flexible catheter are made by transparent plastic material.
