Abstract
The utility model discloses a selective artery intervene retention and perfusion catheter, comprising a columnar injecting medicine joint 1 and a catheter, wherein, one end of the injecting medicine joint 1 is funnel-shaped injecting medicine end, and the other end is interface end and provided with a connecting pipe 2. A puncturing membrane 5 is arranged in the injecting medicine end. One end of the catheter 4 is connecting port, and the other end namely the tail end of the catheter is outward hemispherical protrusion and provided with a cut, forming a cut with a valve for preventing the back flow. The selective artery intervene retention and perfusion catheter provided by the utility model is simple structure, simple preparation process, and adopting profitably the columnar injecting medicine joint. The utility model can be implanted only needing a small cut, with the result that the operation is simple, and the injury is smaller.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates in particular to a kind of medical apparatus and instruments that utilizes conduit and medicine-injecting connector the patient to be carried out topical treatment.
Background technology
The interposing catheter that uses in medical procedure at present can be divided into two classes on structure, a class is to have anti-recirculation device, and another kind of is not have anti-recirculation device.And when the application of radiation interventional method is implanted, can only use the interposing catheter of not being with anti-recirculation device, but need carry out periodic flushing to interposing catheter, frozen plug conduit in case hemostasis liquid backflows with heparin-saline, in a single day stop up as conduit, just can only discard or change again and implant.For above-mentioned two class interposing catheters, owing to it is long-pending big to drug cassette body, when undergoing surgery implantation, operate too complexity, also big to patient's wound.
Summary of the invention
The purpose of this utility model provides a kind of selective arterial and gets involved the indwelling perfusion cannula.The method that it can be under the less situation of wound be got involved with radiation is implanted interposing catheter in patient's body and the blood reflux phenomenon can not taken place.
In order to achieve the above object, the technical scheme that this utility model adopted is: be provided with a cylindrical medicine-injecting connector and conduit; One end of medicine-injecting connector is funnel shaped medicine-injecting end, make puncture needle be easy to aim at the puncture film, the other end is interface end and has connection tube, also is provided with the puncture film in the inside of medicine-injecting end strengthening the sealing of medicine-injecting connector, and the number of plies of puncture film can be one deck, bilayer or three layers; One end of conduit is a connector, and is connected with connection tube on the medicine-injecting connector by connecting valve, and the other end of conduit is that catheter tip is hemispherical evagination, and an otch is arranged, and forms an anti-mouth that backflows that valve is arranged; The shape semicircular in shape otch of described otch.The superslide seal wire can carry out seal wire, conduit exchange by the valve orifice of conduit when the patient is radiated interventional procedure, conduit is introduced target vessel, withdraw from seal wire then, valve orifice recovers to close, and this moment is because catheter tip is the hemispherical evagination, valve can inwardly not opened, blood can not inflow pipe in, and when the pipe internal pressure greater than pipe outside the time, valve can outwards be opened, liquid can flow out from conduit and enter target vessel, thereby reaches anti-purpose of backflowing.Moreover because medicine-injecting connector adopts cylindrical form, only need little otch promptly implantable, can make simple to operately, wound is littler.
Selective arterial provided by the utility model gets involved that to keep somewhere perfusion cannula simple in structure, and processing technology is simple, has in adopting columniform medicine-injecting connector, only needs little otch promptly implantable, thereby makes simple to operately, and wound is littler.
Description of drawings
Fig. 1 is that this utility model embodiment selective arterial gets involved the cross-sectional view of keeping somewhere perfusion cannula.
Fig. 2 is that the catheter tip otch of this utility model embodiment selective arterial intervention indwelling perfusion cannula is the semi-circular cut-out sketch map.
The specific embodiment
In structure shown in Figure 1, be provided with a cylindrical medicine-injecting connector 1 and conduit 4; One end of medicine-injecting connector is funnel shaped medicine-injecting end, make puncture needle be easy to aim at puncture film 5, the other end is interface end and has connection tube 2, also is provided with puncture film 5 in the inside of medicine-injecting end strengthening the sealing of medicine-injecting connector, and the number of plies of puncture film can be one deck, bilayer or three layers; One end of conduit is a connector, and is connected with connection tube 2 on the medicine-injecting connector by connecting valve 3, and the other end of conduit 4 is that catheter tip is hemispherical evagination, and an otch is arranged, and forms an anti-mouth that backflows that valve is arranged; The shape semicircular in shape otch of described otch.The superslide seal wire can carry out seal wire, conduit exchange by the valve orifice of conduit when the patient is radiated interventional procedure, conduit is introduced target vessel, withdraw from seal wire then, valve orifice recovers to close, and this moment is because catheter tip is the hemispherical evagination, valve can inwardly not opened, blood can not inflow pipe in, and when the pipe internal pressure greater than pipe outside the time, valve can outwards be opened, liquid can flow out from conduit and enter target vessel, thereby reaches anti-purpose of backflowing.Moreover because medicine-injecting connector 1 adopts cylindrical form, only need little otch promptly implantable, can make simple to operately, wound is littler.
