Abstract
The utility model relates to a medicine percutaneous control release device that controls the percutaneous plaster dosage which overcomes the disadvantages of the prior art of unstable percutaneous medicine consistency, incapability of maintaining a long time, etc. The device consists of a percutaneous plaster and a control release device, wherein the control release device comprises a fixed box, a flexible anther sac and a control switch, the percutaneous plaster is formed by a percutaneous adhesive plaster and a medicine release bag, the flexible anther sac is positioned inside the fixed box, the medicine added port passes through the fixed and enters the inside of the flexible anther sac; the medicine percutaneous control release device further comprises a connecting tube, one end of the connecting tube is communicated with the flexible anther sac and the other end of the connecting tube is communicated with the medicine release bag of the percutaneous plaster. The utility model enables the disease portion to obtain long term effective therapy and greatly improves therapeutic effect; the medicine can be increased or replaced without frequent replacement of the plaster, and relative stable and lasting medicine consistency can be kept in the percutaneous plaster, thus guaranteeing the reliable therapeutic effect, increasing the utilization rate of the original auxiliary materials, saving the original auxiliary materials and reducing environment pollution.
Description
(1) technical field:
This utility model relates to a kind of drug transdermal controlled-release device that transdermal pastes dose of controlling.
(2) background technology:
Medicine absorbs this method of treatment disease through skin, just brings into use in Ancient Times in China, as " black plaster " that it has often been said, but application in the past only is the simple use that is limited to empirical formula.Modern medicine proves, the skin of human body is the natural cover for defense that the people is isolated from the outside, because the special permeability of skin, determined many materials to be absorbed by the body by skin, under the injury-free situation of skin, have only the permeability that changes skin by chemical factors, could change the quantity of the penetrating skin of medicine.In recent years, the medical scientific research worker absorbs successive dynasties medical science experience and utilizes the modern pharmaceutical technology, develops modernly through skin drug-delivery preparation " preparation capable of permeating skin ", has been used as a modern pharmaceutical technology and has applied.
What preparation capable of permeating skin was commonly used mainly is that transdermal pastes, it is that medicine is placed the release bag, be fixed on the skin, under the effect of transdermal enhancer, strengthen skin and subcutaneous tissue absorbtivity to medicine, to reach a kind of preparation of effective Drug therapy concentration, " strange positive scorching pain is pasted " that produce in this class preparation such as Gansu etc.The making and use method of this class preparation is: pack into medicine in the release bag that fabric does and be fixed on the ventilative adhesive plaster, transdermal enhancer is adorned in addition with hermetic containers such as plastic bags, during use, transdermal agent in the plastic bag is poured in the release bag, and the adhesive plaster that will have a release bag is attached on the skin and treats.
But these transdermals paste and have two deficiencies: the one, and medicine must disposablely be packed in the release bag, and blended rubber cloth fixedly behind the release bag, is attached on the skin, if want to strengthen therapeutic effect, necessary replacing plaster; The 2nd, because transdermal agent is disposable adding, it is big just to have added fashionable amount, promotes transdermal drug level height, after a period of time, transdermal agent is because of multiple former thereby loss, and the minimizing of transdermal agent, must cause the drug transdermal amount to descend, treatment concentration can't be kept for a long time.
(3) summary of the invention:
Deficiencies such as the purpose of this utility model is to overcome transdermal drug concentration instability in the prior art, can not keep for a long time provide a kind of and can in use change or increase and decrease the controlled release device that transdermal pastes medication amount.
Drug transdermal controlled-release device of the present utility model, be made up of transdermal subsides and controlled release device, the controlled release device comprises fixed bin, elasticity medicine bag, gauge tap, and transdermal pastes to be made up of ventilative adhesive plaster and release bag, the elasticity medicine bag is positioned at fixed bin, and dosing mouth passes fixed bin and feeds in the elasticity medicine bag; Described drug transdermal controlled-release device also comprises connection tube, and the one end communicates with the elasticity medicine bag, and the other end communicates with the release bag that transdermal pastes.
This utility model is owing in the controlled release device that medicine is packed into, automatically and in artificial at regular time and quantity the release bag that drug releases such as transdermal enhancer are pasted to transdermal, make skin stable and see through a certain amount of medicine for a long time, transdermal enhancer and drug level do not successively decrease, the dose that controlled release sufferer place sees through, keep transdermal drug concentration and action time, thereby patient part is obtained the effective treatment for a long time, improved therapeutic effect greatly; Need not change plaster often, just can increase or change medicine, make in the transdermal subsides and remain relatively stable and persistent drug level, thereby guaranteed reliable therapeutic effect, increase the utilization rate of former auxiliary material, saved former auxiliary material, reduced environmental pollution.Stable and the release at regular time and quantity of medicine.
(4) description of drawings:
Fig. 1 is the structural representation of this utility model drug transdermal controlled-release device.
(5) specific embodiment:
Below in conjunction with accompanying drawing this utility model is described in further detail.
As shown in the figure, this utility model drug transdermal controlled-release device, form by transdermal subsides and controlled release device, the controlled release device comprises fixed bin 7, elasticity medicine bag 6, gauge tap 8, transdermal pastes to be made up of ventilative adhesive plaster 1 and release bag 2, elasticity medicine bag 6 is positioned at fixed bin 7, and dosing mouth 5 passes fixed bin 7 and feeds in the elasticity medicine bag 6; The drug transdermal controlled-release device also comprises connection tube 4, and the one end communicates with elasticity medicine bag 6, and the other end communicates with the release bag 2 that transdermal pastes.Be provided with release 3 in the release bag 2 that transdermal pastes.Connection tube 4 is provided with gauge tap 8.
During use, medicine is packed in the controlled release device, because the elastic force effect of elasticity medicine bag 6 and the effect of gauge tap 8, medicine can automatically or be pressed the artificial flow velocity of setting, medicine such as liquid transdermal agent inflow transdermal is at regular time and quantity pasted in the release bag 2, mix with fixed drug wherein, make skin stable and see through a certain amount of medicine for a long time.Transdermal pastes can split with the controlled release device, when needing to increase medicine, with connection tube transdermal is pasted and to be communicated with the controlled release device.
