Abstract
The utility model relates to a retention guide pipe for dialysis, which belongs to medical equipment. The utility model has the technical scheme that a side hole steel needle core is outward sheathed with a guide pipe; the middle part of the guide pipe is provided with external threads; the periphery of the guide pipe is sheathed with a cavity wing of internal threads engaged with the external threads; the tail part of the guide pipe is an extension pipe on which a clip is arranged; the front part of the guide pipe is inserted into a blood vessel following the puncture of the side hole steel needle core during dialysis; after a steel needle is withdrawn, the front part of the guide pipe still remains in the blood vessel; the position where the front part of the guide pipe remains in the blood vessel is provided with a cross-section softness head, and accordingly, the guide pipe stretches in the blood vessel and does not damage intimae; the extension pipe can rotate, and accordingly, the guide pipe stretches to the optimum position in the blood vessel, and the blood flow and the damage that the negative pressure acts on the vessel wall are reduced; the guide pipe is made from poly carbamate material and has the advantages of torsion resistance, compression resistance, no deformation and high blood flow. The utility model solves the problem that an existing disposable steel needle for hemodialysis brings various diseases when patients who carry out chronic hemodialysis have repeated puncture and long time hemodialysis. In addition, the hemodialysis using the guide pipe is convenient. After the side hole steel needle core is withdrawn, the clip is lightly clamped and the tail end of the extension pipe is sheathed with a heparin cap to close the guide pipe. The hemodialysis can be carried out next time by loosening the clip and taking the heparin cap off.
Description
(1) technical field: this utility model relates to the conduit that hemodialysis is used, and belongs to medical apparatus and instruments.
(2) background technology:
The general patient who suffers from diseases such as uremia need carry out hemodialysis, promptly blood being extracted in the body gets back in the body behind circulating purification outside, at first need set up a blood vessel access, can vascular access guarantee that enough blood flows are the key factors of influence dialysis success or not.The existing puncture needle of setting up the vascular access employing is the disposable wearing pricker of steel, and produce following problem thus: 1. the invar pin is too hard, must extract out after dialysis finishes, and can not keep in the what blood vessel, so every dialysis once all need be punctured once.2. generally dialyse weekly 3 times, dialysed 4 hours at every turn, in reaching 4 hours dialysis times, patient easily punctures blood vessel if limb activity is arranged.3. puncture vessel radial artery, foot tremulous pulse and brachial artery to be obtaining enough blood flows, but vessel position is dark, and repeated localised puncture is difficult to successfully, easy concurrent hematoma, massive hemorrhage; And anthemorrhagic difficulty during massive hemorrhage.4. the sound that punctures internal fistula can be by performing the operation the distal limbs tremulous pulse and closing on vein and coincide subcutaneous, the postoperative vein is won expansion arteryization, can be after the maturation for puncture, but easy concurrent hand swelling, steal blood syndrome, aneurysm, thrombosis, hemorrhage, congestive heart failure, blood flow deficiency, influence patient's blood circulation.
(3) summary of the invention:
The dialysis inlying catheter that the utility model proposes solves the disposable draw point that above-mentioned existing hemodialysis is used exactly, the various diseases problem that the chronic hemodialysis patient is brought.
Its technical scheme is as follows:
The dialysis inlying catheter is characterized in that being provided with side opening draw point core 5 and is enclosed within the conduit of its outside that this conduit is divided into following three parts: the conduit front portion 1 in what conduit the place ahead, position; What conduit stage casing, position and outer surface are provided with externally threaded conduit middle part 2, be with the chamber wing 4 that contains the female thread that is meshed with external screw thread in its periphery, and externally threaded length are 1/4 of female thread; Catheter tail is equipped with clip 6 for prolonging pipe 3, prolonging on the pipe, and this place's tail end is suit calparine cap 7 when no side opening draw point core.
The soft head in above-mentioned conduit dress cross section, anterior 1 foremost.Above-mentioned conduit can adopt the polyurethane material.The above-mentioned chamber wing can adopt the transparent flexible material.Above-mentioned prolongation pipe can adopt the transparent flexible material.
This utility model beneficial effect:
When i. dialysing, conduit front portion 1 is extracted side opening draw point core 5 out after inserting in the blood vessel with 5 punctures of side opening draw point core then, clamps clip 6, puts calparine cap 7.When the needs dialysis purifies the blood, only need take off calparine cap, connecting outer circulation hemodialysis pipe can carry out.Dialysis this time finishes rear tube front portion 1 and can be retained in the human vas always, and dialysis later on need not prevent prolonged and repeated draw point puncture and insert the above-mentioned various diseases that the long-time dialysis of draw point brings to the patient, and make hemodialysis very convenient with each puncture.Ii. the chamber wing is fixed on the skin, because of being provided with female thread, external screw thread cooperation, when making dialysis, can prolonging by rotation and manage 3, and the conduit front portion is elongated or shortened in blood vessel, guarantees the optimum position, to reduce blood flow and negative pressure to vascular damaged.Iii. the conduit front portion is embedded in and locates in the blood vessel to establish transversal thin-skinned head, the conduit front portion is elongated or shortened in blood vessel do not damage inner membrance, and blood flow is the highest.Iv. conduit polyurethane material, anti-twist, anti-positive negative pressure, indeformable provides blood flow to reach 150～300ml.V. the chamber wing adopts the transparent flexible material, can conveniently see the length of the anterior intravasation of conduit.Vi. prolong pipe and adopt the transparent flexible material, can in the shortest time, observe blood back.
(4) description of drawings:
Fig. 1 this utility model front view
After Fig. 2 Fig. 1 extracts side opening draw point core out, the partial sectional view during closes ducts
(5) specific embodiment:
See Fig. 1, conduit polyurethane material.Anterior 1 front end of conduit is adorned transversal thin-skinned head, all puts in the what human vas.Conduit middle part 2 outer surfaces have external screw thread, and outer cover is equipped with the chamber wing 4 of the usefulness transparent flexible material of female thread, and internal and external screw thread is meshing with each other, and external thread length is 1/4 of a female thread.The prolongation pipe 3 of catheter tail for making of transparent flexible material material is equipped with clip 6 on it, prolonging pipe tail end outside has external screw thread, sees Fig. 2, and after side opening draw point core 5 was extracted out, this place loaded onto calparine cap 7, in order to closes ducts.
Using method and process:
1. with sheathed catheter at side opening draw point core 5 outer surfaces, conduit front portion 1 is inserted blood vessel in the lump with side opening draw point core 5 and is punctured.2. punctured and extracted side opening draw point core 5 out, conduit front portion 1 is retained in the blood vessel.3. clamp the clip 6 that prolongs on the pipe 3, put calparine cap 7.4. the chamber wing 4 is fixed on the skin.When 5. carrying out hemodialysis, take off calparine cap, put the hemodialysis pipeline, unclamp clip 6, blood enters the exterior line circularly purifying and promptly dialyses.6. rotatable prolongation pipe, the transversal thin-skinned head of conduit front portion 1 elongates or shortens in blood vessel, guarantees the optimum position, can reduce blood flow and negative pressure to vascular damaged.Injecting heparin liquid when 7. dialysis finishes clamps clip, is with calparine cap.8. the conduit front portion is retained in the blood vessel, and the time that is retained in the radial artery, brachial artery, dorsal artery of foot, great saphenous vein is long, does not need every thorn to puncture, and makes things convenient for hemodialysis.
