Technical field
This utility model relates to a kind of medicine applying device for rectum, belongs to medical instruments field.
Background technology
In order to solve the problem that it is difficult that child and especial patient are taken medicine, have an injection, infused, in recent years, the Therapeutic Method of rectally obtains energetically popularization at basic medical unit, and is subjected to the welcome and the approval of numerous children and family numbers of patients deeply.
In general, rectally mainly contains three approach, and the one, enter liver by superior rectal vein through portal vein and carry out being recycled to whole body after the metabolism; The 2nd, walk around liver by hemorrhoidal veins,middle and inferior rectal veins and anal canal vein and directly enter the blood systemic circulation; The 3rd, after the absorption of rectum lymphsystem, by newborn pond, thoracic duct enters blood circulation.Rectally can prevent or reduce toxicity and the side effect of medicine to liver.Studies show that: rectally and intravenously administrable produce effects speed no significant difference, but the bioavailability of rectally doubles than oral administration.In addition, rectally has been avoided the feared state of mind of children's to having an injection, taking medicine, and having alleviated medicine stimulates gastrointestinal, helps bringing into play therapeutical effect, especially be applicable to old people, child, severe crisis and long-term bed person, depleted patient and be difficult to medication person, household remedy is also very convenient.
In the existing medical skill, also there is not special unified medicine applying device for rectum.Clinically, often need to adopt the medication of medicine being sent into rectum by anus.Generally be that the sealing part of containing the bottleneck front end of medicine is cut off, elongated bottleneck inserts anus and extrudes medicinal liquid as the pipeline of drug delivery.Because the bottleneck clip is comparatively sharp, during insertion, can damage mucous membrane of rectum, the little air that bottleneck has also can at first be squeezed into rectum, and side effect is bigger, and does not indicate scale on this bottleneck, can not control timely dosage at any time, and this kind administering mode is easy to the hands of making dirty.Thereby, still can't extensive use in actual medication process.
The utility model content
Technical problem to be solved in the utility model provides a kind of medicine applying device for rectum, and is simple in structure, easy to use, and health, practicality can extensively be promoted the use of.
In order to achieve the above object, this utility model is realized by the following technical solutions:
A kind of medicine applying device for rectum, comprise a cartridge syringe and the hygienic protection cover that is enclosed within on the described cartridge syringe in order to storage of pharmaceutical and double as injection, described cartridge syringe comprises one in order to the injection tube of storage of pharmaceutical and the injection ram in the described injection tube of insertion; End face center at the dispensing end of described injection tube offers a medicine injection port; the cover closedtop of described hygienic protection cover closes and is provided with a drug blockage plug that inserts in the described medicine injection port at envelope top inner face; it is characterized in that; the oral area that imports end at the injection ram of described injection tube be provided with outward extending just with two fingerhold promoting the folder wing of injection ram motion, become 90-150 ° of angle between the barrel of the described folder wing and injection tube.
This utility model can carry out following improvement:
The injection tube of described cartridge syringe is an overall structure, and this injection tube profile is a cone structure, and inside is straight barrel structure, so that the pushing of injection ram; Described injection tube changes software strategy into software-hardware strategy from small end to big extreme direction hardness.
Perhaps, described cartridge syringe is for dividing body structure, comprise syringe and a drug storage pipe of a routine, described medicine-storing tube profile is a cone structure, and there is medicine inside, head center at described drug storage pipe offers the medicine injection port, afterbody is provided with seal cover, during use, seal cover is removed, then the drug storage pipe is inserted on the syringe needle of syringe, the pushing syringe piston can be injected away the medicine in the drug storage pipe.
Described drug storage pipe changes software strategy into software-hardware strategy from small end to big extreme direction hardness.
In order to show the injection amount, be shown with scale mark at described injection tube or drug storage pipe subscript.
Medicine applying device for rectum of the present utility model, simple in structure, easy to use, health, practicality; Be applicable to old people, child, severe crisis and long-term bed person and depleted patient and be difficult to medication person, household remedy is also very convenient.
