This embodiment provides a drug delivery tube, as shown in fig. 1-7, comprising:
a drug delivery hose 100;
the guide wire 200 is used for extending into the administration tube 100, assisting in positioning the specific position of the administration tube 100 and judging the smoothness of the administration tube 100; the guide wire 200 comprises a metal rope 210 and a friction hose 220, wherein the friction hose 220 is sleeved at one end of the metal rope 210 extending into the administration hose 100;
the administration head 300 is provided to be mounted at one end of the administration tube 100 to transfer the medicine into the administration tube 100.
When the administration tube in this application is used, at first insert the seal wire 200 front end into the administration hose 100, connect fixedly, stretch into the appointed position with the administration hose 100 through the enteroscope, then separate seal wire 200 and the administration hose 100 and extract, install the head 300 of dosing in the end of the administration hose 100, shift appointed liquid medicine into the administration hose 100 through the head 300 of dosing to with the liquid medicine from the other end of the administration hose 100 to the intestinal tract wait to dose the position, convenient operation. In order to facilitate multiple administration, the administration head may be fixed by using a medical adhesive tape or the like after the administration is completed, for example, the administration head may be fixed on the waist of a patient, thereby minimizing the influence on the movement of the patient.
When the enteroscope probe is taken out after the enteroscope is completed, the guide wire 200 can be pushed, so that the friction force between the guide wire 200 and the administration hose 100 overcomes the friction force between the enteroscope probe and the administration hose 100, and the administration hose 100 can be kept at a specified position and is not carried out by the enteroscope.
In this embodiment, the guide wire 200 may be used to assist the administration tube 100, so that the administration tube 100 may be conveniently extended to a designated position, and the operation difficulty is reduced and the operation efficiency is improved.
In this embodiment, when the length of the administration tube 100 is long enough, the guide wire 200 may not be inserted into the administration tube, and the administration tube 100 is extended to a designated position by the enteroscope, but in this case, when the enteroscope probe needs to be taken out, the administration tube 100 needs to be manually pushed to overcome the friction between the enteroscope probe and the administration tube 100, which is inconvenient in operation, and at this time, the guide wire 200 may assist in positioning the position and smoothness of the administration tube 100 during the retention of the administration tube 100 in the body.
In this embodiment, after the administration tube 100 is left in the body, the guide wire 200 may be inserted into the administration tube 100 to test the patency, and the position and shape of the administration tube 100 may be determined by using the metal property by using x-rays.
The metal cord 210 in this embodiment is a metal soft cord, where the soft finger can deform under external force, for example, can adapt to the direction of the intestinal tract in the intestinal tract, and cannot break, and a material meeting medical standards, for example, medical stainless steel, needs to be selected.
The end of the metal rope 210 in this embodiment is sleeved with a friction hose 220, the inner diameter of the friction hose 220 is matched with the outer diameter of the metal rope 210, and the outer diameter of the friction hose 220 is matched with the inner diameter of the administration hose 100 or has a slight gap, so that friction forces exist between the friction hose 220 and the metal rope 210 and between the friction hose 220 and the administration hose 100, so that the force acting on the metal rope 210 by an operator can be conducted to the administration hose 100, and the administration hose 100 and the metal rope 210 are not easy to separate.
The friction hose can be a PVC hose or a silica gel hose, and the metal rope 210 directly penetrates into the administration hose 100, so that the end of the metal rope 210 can damage the administration hose 100, and the friction hose 220 can relieve or even avoid damage to the surface of the administration hose.
In some embodiments of the present application, a stop 230 is provided at an end of the guide wire 200 that does not extend into the administration tube 100.
The limiting part 230 prevents the guide wire 200 from completely entering the administration tube 100 and being unable to be taken out, and is convenient for the operator to hold.
In some embodiments of the present application, a drug outlet hole 110 is provided on a side wall of the drug delivery hose 100, and the drug outlet hole 110 is disposed near a drug outlet end of the drug delivery hose 100.
The treatment site is generally located on the intestinal wall, and in order to make the treatment site fully contact with the liquid medicine and improve the absorption effect of the liquid medicine, the medicine outlet hole 110 may be disposed on the side wall of the medicine delivery hose 100, and in general, the medicine outlet hole 110 is located on the side wall of the medicine outlet end portion.
Specifically, the drug outlet end of the drug delivery hose 100 is generally an opening, and when the drug outlet hole 110 is formed in the sidewall of the drug outlet end, the drug outlet end of the drug delivery hose 100 can be closed, so that as much drug liquid as possible can be flushed to the position to be treated, and more drug liquid passes through the position to be treated, thereby improving the treatment effect.
