Embodiment Construction

[0014] according to figure 1 As shown, an external interface 1.1 is provided on one side of the tube body 1 of the tubular object, a conical tube head 1.3 is provided on the opposite side, and drug leakage holes 1.5 are distributed on the tube wall 1.2. There are pipe head oblique holes 1.6.

[0015] The distance a between the drug seepage holes is 5-10 mm, and the distance b is 2-6 mm.

[0016] The drug seepage hole can also be a mesh structure, and the mesh diameter is 0.5-1mm.

[0017] Tube walls are made of polyamide rubber.

[0018] The tube wall can also be made of chitin polysaccharide.

[0019] Features of the introduction tube of the present invention

[0020] 1. Drug leakage holes are distributed on the tube wall, which is conducive to the dispersion of the introduced drug in the gangrene tissue, and keeps the wound moist, which is conducive to tissue growth.

[0021] 2. The polyamine rubber tube and chitin tube used have good tolerance to the human body and do ...

Abstract

The present invention provides a duct for delivering medicine used to cure the diabetic gangrene part caused by diabetes. An external port is arranged on one end of a tubular duct body, and a tapered duct head is arranged on the opposite end; medicine-seeping pores are distributed on a duct wall; the duct head is provided with oblique duct head holes; the medicine-seeping pores are intervallically arranged or can be arranged into a netty structure; the duct wall is made of polyurethane rubber or made from chitin polysaccharide. Since the material of the duct of the present invention adopts polyurethane or chitin, a rejection reaction cannot occur when the duct is inserted into the tissues of the human body, and meanwhile, since the duct is soft, the duct can be conveniently extended into the tissues, which is favorable for the seepage and distribution of the medicine. The medicine-delivering effect is obvious, the curative effect is good, and the amputation rate and the death rate are reduced. The duct is suitably applied in the delivery of medicine for curing diabetic gangrene tissues.

Description

technical field [0001] The invention proposes a drug introduction tube for treating diabetic gangrene caused by diabetes. Background technique [0002] Before the present invention was proposed, the treatment of gangrene caused by diabetes was usually to cut off the gangrene tissue by operation, or perform amputation, which would cause disability to the diabetic, and even endanger life. [0003] The currently developed treatment method is to introduce the drug for treating diabetes into the gangrene tissue through the method of drug introduction, and through the action of the drug, it can achieve the therapeutic effects of promoting blood circulation, removing stasis, reducing inflammation and pain, and removing saprophysis. [0004] The existing drug introduction tube is usually replaced by the existing infusion tube, which has a lumen structure. The disadvantages are: hard quality, poor comfort; single-hole straight tube cavity, which is not conducive to the dispersion and...
