Abstract
The utility model provides a drug carrier which solves a technical problem that a drug cannot be accurately positioned as the drug carrier for positioning a digestive tract inner wall does not exist in the prior art. The drug carrier comprises a body with a channel inside, wherein the two ends of the body are equipped with openings communicated with the inner channel; the body is made of a magnetic material; and the body is tubular. The drug carrier disclosed by the utility model has effect of being capable of accurately positioning the drug on each position of the digestive tract inner wall, so that drug properties of the drug are brought into play quicker, and therefore, treatment effect is improved.
Description
Technical field
This utility model relates to a kind of pharmaceutical carrier, particularly a kind of ganoid O type pharmaceutical carrier.
Background technology
Pharmaceutical carrier refers to that can change medicine enters the mode of human body and distribution in vivo, controls the rate of release of medicine and conduct drugs to the system of target organs.The material that existing pharmaceutical carrier adopts generally has meeting to the side effect of human body output, or brings damage to human body.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of pharmaceutical carrier, and this pharmaceutical carrier has the advantages that to have no side effect.
The purpose of this utility model can realize by following technical proposal: a kind of pharmaceutical carrier, comprise that inside has the body of passage, described body two ends all have the opening being connected with inner passage, it is characterized in that, described body adopts ferriferrous oxide material to make, and described body in a tubular form, the cross section of described body is circular, the two ends of described body all have rounding, and the external diameter of described body is 0.2mm-0.5mm, and the length of described body is 0.1mm-0.3mm.
The external diameter of described body is 0.3mm, and the length of described body is 0.2mm.
Ferroso-ferric oxide is high-purity harmless material, can not have side effects to human body, and in addition, external diameter and the length of body are all less, easy to use taking; In a tubular form, the cross section of body is circular to body, and the two ends of body all have rounding, so also can reduce the damage that user causes intestinal after taking.
Compared with prior art, this pharmaceutical carrier has the following advantages:
1, body adopts ferriferrous oxide material to make, and high-purity harmless material improves safety.
2, medicine is installed in body, body is under existing externally-applied magnetic field effect or under the effect of additional magnetic guiding system, and body and medicine enter can be accurately positioned in after human body needs treatment position in human body.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, body; 11, passage; 12, opening; 13, rounding.
Detailed description of the invention
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but this utility model be not limited to these embodiment.
As shown in Figure 1, a kind of pharmaceutical carrier, comprises that inside has the body 1 of passage 11, and described body 1 two ends all have the opening 12 being connected with inner passage 11, and described body 1 adopts magnetic material to make, and described body 1 in a tubular form.
Described body 1 adopts ferriferrous oxide material to make, and the magnetic characteristic of material is adjusted to better level, initial permeability > 50; The corrosion of saturation magnetization Bs > 100Guss and ability low concentration strong acid.Body 1 also needs polishing processing, makes body 1 smooth surface, is difficult for causing the scratch of digestive tract wall.
The cross section of described body 1 is circular.
The two ends of described body 1 all have rounding 13.
The external diameter of described body 1 is 0.2mm-0.5mm, and the length of described body 1 is 0.1mm-0.3mm; In the present embodiment, the external diameter of body 1 is 0.3mm, and the length of described body 1 is 0.2mm.
The manufacture process of this pharmaceutical carrier: 1, batching; 2, use the molding of ultra-fine bar magnet former; 3, sintering; 4, be cut into thin tube-like; 5 polishings.Can reach above-mentioned requirements.When use, can use easily vacuum to fill with liquid, vacuum drying, makes medicine be filled to body 1 inside.Under existing externally-applied magnetic field effect or additional magnetic guiding system, pack the suitable gravitation of body 1 of medicine into, make it rest on treatment desired location.
Body 1 adopts ferriferrous oxide material to make, therefore be that tool is magnetic, in the present embodiment, externally-applied magnetic field is prior art, such as the guiding magnetic field adopting in " Acta Physica Sinica " 2006 08 interim disclosed " theory analysis of guiding magnetic field magnetic drug targeting treatment "; Additional magnetic guiding system is also prior art, and such as the magnetic guiding system that Olympus Medical Systems Corp. applies for and authorizes, the patent No. of this patent is: 201110206403.8.
Specific embodiment described herein is only to the explanation for example of this utility model spirit.This utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used 1 herein, body; 11, passage; 12, opening; 13, the term such as rounding, but do not get rid of the probability that uses other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with this utility model spirit.
Claims (2)
1. a pharmaceutical carrier, comprise that inside has the body of passage, described body two ends all have the opening being connected with inner passage, it is characterized in that, described body adopts ferriferrous oxide material to make, and described body in a tubular form, the cross section of described body is circular, the two ends of described body all have rounding, and the external diameter of described body is 0.2mm-0.5mm, and the length of described body is 0.1mm-0.3mm.
2. pharmaceutical carrier according to claim 1, is characterized in that, the external diameter of described body is 0.3mm, and the length of described body is 0.2mm.
