Description
The technical field is as follows:
the utility model relates to a drug delivery tube, in particular to an intestinal drug delivery tube.
Background art:
the intestinal administration is one of drug therapies of administration through intestinal mucosa, and the drug is injected into local intestinal tract through an intestinal administration tube and absorbed through mucosa, thereby achieving the local and systemic curative effects. The intestinal administration has the advantages of no wound, complete and rapid drug absorption, direct action on the local part of pathological changes, remarkable curative effect compared with the systemic administration, less toxic and side effects, no pain to patients and the like, and is particularly suitable for clinical treatment. However, at present, the intestinal administration is only limited to the rectal administration by using a rectal administration tube in clinic, and for the pathological changes at the deeper part of the intestinal tract, the drug is administered by the rectal administration tube, the drug can hardly reach the pathological change part, the curative effect is slight even if a small amount of drug reaches, and the drug can not be intensively acted on the pathological change part.
The utility model content is as follows:
in order to overcome the technical problems that the currently used intestinal administration tube cannot reach the deep part of the intestinal tract and the local medicine dosage of pathological changes is insufficient, the utility model provides the intestinal administration tube which has the advantages of simple structure, reasonable design, obvious administration effect and attractive appearance, and can reach the deep part of the intestinal tract.
In order to achieve the technical purpose, the utility model adopts the technical scheme that: an intestinal administration tube, which consists of an administration tube (1) and an administration hole (2), and is characterized in that the front part of the administration tube (1) is provided with a small section of administration tube insertion section (3), the administration tube insertion section (3) is fixedly connected with a front end air bag (4), the front end air bag inflation tube (5) is positioned on the inner wall of the administration tube (1), the front end air bag (4) is fixedly connected with a front end air bag check valve (6) through the tail end of the front end air bag inflation tube (5), the tail end of the administration tube (1) is fixedly connected with a positive pressure infusion joint (7), the exterior of the administration tube (1) is provided with a sleeve (8), the front end of the sleeve (8) is fixedly connected with a rear end air bag (9), the rear end air bag inflation tube (10) is positioned on the inner wall of the sleeve (8), the rear end air bag (9) is fixedly connected with a rear end air bag check valve (11) through the tail end of the rear end air bag inflation tube (10), the administration tube (1) can be inserted into the sleeve (8), the outer diameter of the administration tube insertion section (3) is smaller than the outer diameter of the administration tube (1), the outer diameter of the administration tube (1) is equivalent to the inner diameter of the sleeve (8), the administration tube (1) and the sleeve (8) are both long enough, and the length of the administration tube (1) is larger than that of the sleeve (8).
After the intestinal administration tube adopts the structure, the administration tube is inserted into the sleeve, the administration tube is inserted into a pathological change part of the intestinal tract under the assistance of an endoscope, the position of the front end air bag is adjusted to be positioned at the far side of the pathological change part, the front end air bag is inflated, the sleeve is pulled backwards, the position of the rear end air bag is adjusted to be positioned at the near side of the pathological change part, then the rear end air bag is inflated, and then the medicine is injected through the positive pressure infusion joint. Enough length like this can guarantee it and reach colon depths with the sleeve pipe, it can guarantee under the empty deficiency state of front end gasbag to reduce with the pipe inserted section external diameter, it can pass through the sleeve pipe smoothly to give the pipe inserted section, it is equivalent with the sleeve pipe internal diameter to give the pipe external diameter, can prevent that the liquid medicine from leading to the fact the medicine extravagant and polluting external environment through the clearance backward flow between pipe and the sleeve pipe of dosing, front end gasbag and rear end gasbag block up the intestinal cavity, can prevent that the liquid medicine from flowing around, make the medicine fully remain in pathological change part, guarantee medicine dose and effect of dosing, it can be according to the length of pathological change and the distance between two gasbags of needs treatment range adjustment to be equipped with the sleeve pipe, accomplish and dose in the fixed range. This intestinal administration tube simple structure, reasonable in design can reach the intestinal depths, can administer in the fixed range, and the effect of dosing is showing, but the wide application is in the intestinal operation of dosing.
Description of the drawings:
FIG. 1 is a schematic view of the specific structure of the administration tube of the present invention:
fig. 2 is a specific structural schematic diagram of the bushing of the present invention:
1. administration tube 2, administration hole 3, administration tube insertion section 4, front end air bag 5, front end air bag inflation tube 6, front end air bag check valve 7, positive pressure infusion joint 8, sleeve 9, rear end air bag 10, rear end air bag inflation tube 11, rear end air bag check valve
The specific implementation mode is as follows:
the intestinal administration tube and the sleeve are both made of polyurethane materials. The front part of the administration tube 1 is provided with a small section of administration tube insertion section 3, the administration tube insertion section 3 is of a solid structure, the end is smooth, a front end air bag 4 is wrapped on the administration tube insertion section 3, a plurality of administration holes 2 are arranged on the side wall of the small section of administration tube 1 behind the front end air bag 4, the front end air bag inflation tube 5 is positioned on the inner wall of the administration tube 1, the front end air bag 4 is fixedly connected with a front end air bag check valve 6 through the tail end of the front end air bag inflation tube 5, the tail end of the administration tube 1 is fixedly connected with a positive pressure infusion joint 7, the exterior of the administration tube 1 is provided with a sleeve 8, a rear end air bag 9 is wrapped on a small section of the front end of the sleeve 8, the rear end air bag inflation tube 10 is positioned on the inner wall of the sleeve 7, the rear end air bag 9 is fixedly connected with a rear end air bag check valve 11 through the tail end of the rear end air bag inflation tube 10, the administration tube 1 can be inserted into the sleeve 8, the outer diameter of the administration tube insertion section 3 is smaller than the outer diameter of the administration tube 1, the outer diameter of the administration tube 1 is equal to the inner diameter of the sleeve 8, the administration tube 1 and the sleeve 8 have enough length, and the length of the administration tube 1 is larger than that of the sleeve 8.
