The endothelium is highly irritating, and long-term use can cause phlebitis or even venous thrombosis. Once these conditions occur, the patient will need to undergo repeated venipuncture during the treatment ( Ven〇_puncture) to establish the official route of intravenous injection to maintain the treatment, which not only makes the patient suffer from the pain of treatment, but also suffers from the treatment. Therefore, the implanted U-tube injection seat (P 〇rt A) plays a very important role in today's medicine. • The conventional implanted artificial ash tube (Port A catheter) is clinically used as a long-term placement of artificial win-tube access. Its material is composed of titanium metal and Shixia compound, which has high biocompatibility, so it can be completely implanted in the body and placed for a long time. The conventional implanted manual tube injection seat has a portal (Portal) and a catheter with a lock (Cathete. The entire system is completely implanted under the skin. The end of the catheter is placed in the right atrium, and the injection seat is usually placed. On the chest wall, there is a self-coupling diaphragm that can be used to puncture the skin with a special curved needle and to separate the M368453 membrane from the injection seat. Unlike the external catheter system, the implantable artificial blood vessel injection seat does not need daily The placement of conventional implantable artificial blood vessels is generally performed by subclavian vein, internal jugular vein, or cephalic vein. The general surgical procedure is performed by a surgeon. Performed in the operating room, before the local anesthesia is injected on the surface of the skin, the injection seat of about 1 硬币 coin size is placed under the skin on the chest, and the sputum catheter connected to the vascular injection seat is placed in the large blood vessels of the body. Inside, as a result, when the patient needs intravenous chemotherapy, there is no need to worry that there is no suitable blood vessel for injection, and the injected medicine is sent directly to the body. In the large blood vessels, the risk of hardening of the injected blood vessels and skin ulceration caused by the drug can be avoided. May 7th to 9th, however, the implantable artificial blood vessel injection seat (60) still used today is still Unexpected, in which the catheter (62) break is still a clinically common complication, and once these complications occur, the patient will be removed or adjusted again. This is not only an increase. The pain of the patient also compromises the continuity of the treatment. The implantable artificial blood vessel injection seat (6 〇) currently available on the market consists of three components, the injection port (6). 1), a catheter (6 2 ) and a cap (the cap) (61) form an injection chamber. In the composition, the catheter (62) is placed over the injection seat ( 6丄) The connection is made on the cassette where the connection cap is stuck at the connection, so the connection is the vulnerable part of the implantable artificial blood vessel injection seat (60), and the catheter is easy to appear here (6 M368453 2 ) Breaking. There is also a joint at the market. Molded implantable vascular injection seat. However, this implantable artificial blood vessel injection seat is only available for injection-injection top surface (6 1 2), and the injection hole is located directly above the injection seat (6 2 ). When entering, the metal wire (7 〇) must be turned 9 degrees to enter the catheter (6 2) 'caused to be difficult to implant (as shown in Figure 8), and the conventional metal wire (7) 0) It is necessary to align the opening of one end of the injection sheath and insert the action phase. When it is inconvenient, the conventional implantable artificial blood vessel injection seat (Θ 0 ) has a small diameter or a large blood vessel angle in the patient. In the case, there are many problems such as not easy to implant, and thus it can be seen that the current implantable artificial blood vessel injection seat (6 〇) still has many problems, and it is necessary to improve. [New content] The technical problem to be solved: The implantable artificial blood vessel injection seat used today is still not ideal. The catheter is still a clinically common complication. Once these complications occur, Have the patient receive the surgical seat removal again # or adjust. This not only increases the suffering of patients, but also makes the treatment continuity and discount. The implantable prosthetic injection site currently available on the market consists of three components, namely, the injection seat (p0rt), the catheter (catheter) and the cap. In the composition, the catheter is placed at the junction of the injection seat, and the connection cap is stuck on the connection of the connection, so the connection is a relatively fragile place of the implantable artificial blood vessel injection seat, and the catheter is easy to appear here. fracture. At present, only the implanted artificial blood vessel injection seat, which is integrally formed by the connection of the company, is produced on the market. However, this implantable injection seat has only one injection top surface for injection, and the injection hole is located directly above the injection seat. When implanted, the metal wire must be turned 9 degrees to enter the guide 5 M368453 The tube causes the implantation problem to be difficult. In addition, the conventional metal wire must be inserted into one end of the injection sheath, and the insertion action is rather inconvenient. Therefore, the implantable artificial blood vessel injection seat has a small diameter in the patient's blood vessel or When the blood vessel angle is large, there are various problems such as not easy to implant, and thus, there are still many problems in the current implantable artificial blood vessel injection seat. Solving the technical characteristics of the communication: providing an improved artificial blood vessel injection seat structure, comprising: an injection seat and a catheter. Wherein, the injection seat system comprises an injection chamber, an intensified "main shot top surface and a enhanced injection side; the material tube is connected to one side of the / main shot body, and the enhanced injection side is corresponding to the injection tube. On the other side of the seat body, the duct body is integrally formed with the injection seat body. Wherein, the artificial blood vessel injection seat structure further comprises a metal wire, and the metal wire is coated with a coating film. Wherein the metal wire further comprises a length, the length is about 5 〇 cm 八. The artificial tubular injection seat structure further comprises an injection sheath having a side opening for facilitating insertion of the metal wire into the injection sheath Inside. Wherein the metal wire has a curved end, and the curved end is slightly curved. The stomach-enhanced top surface and the reinforced injection side are integrally formed. In contrast to the efficacy of the prior art: -, ^ injection of the creation of the towel (four) in addition to the same - "intensified injection top surface, but also includes a reinforced injection side, the reinforced injection side (four) refers to the main perforation on the side of the injection seat, And the side of the reinforced injection is located on the side of the connecting catheter" η to effectively facilitate the path of the metal wire (Wire) into the catheter, and there is a solution to the use of implanted human vascular injection seat in the vessel diameter of the patient or M368453 blood camp It is not easy to implant and other problems when the angle is large. 1. The creation of the injection sheath has a side opening design, which can be easily inserted directly into the metal wire. It is not necessary to find an opening of the injection sheath as in the prior art, and it is also accurately aligned with one end opening. The metal wire can be placed into the injection sheath. Third, the creation of the catheter system and the injection seat body structure can effectively strengthen the structural strength of the artificial blood vessel injection seat, and effectively improve the problem that the connection between the conventional catheter sleeve and the injection seat is relatively weak. The techniques, means and functions of the present invention will be described in detail with reference to the preferred embodiments and the detailed description of the drawings, and it is believed that the above-mentioned objects, structures and features of the present invention can be obtained from an in-depth and specific understanding. .

Wherein, the artificial blood vessel injection seat structure further comprises a metal wire (3〇), and the metal wire (30) is coated with a coating film. The length of the metal wire (30) is about 5 cm. Wherein, the artificial blood vessel injection seat structure further comprises an injection sheath (4 〇), the sheath (40) has a side opening (4 1 ), thereby facilitating the metal wire M368453 (3 〇) to fit into the injection sheath ( 4 〇). Wherein, the metal wire (30) has a curved tip (3 1 ), and the curved tip (3 i ) is a micro-arm curved shape, which is more practical in use. The conventional metal wire J-shaped end U-tip) is so curved. Wherein, the reinforced injection top surface (12) and the reinforced injection side surface 3) are integrally formed. In addition, the method of using the improved artificial gold tube injection seat structure provided by the present invention is as follows: 1. This creation department uses the same cephalic vein as the implantation catheter (2 〇) like the conventional implanted artificial blood vessel. The first choice, if the blood vessels are very J, the Pect〇ral is major can be turned up to find the perforator vein. 2. Select the appropriate catheter (2〇) size and length according to the size of the vessel diameter. Vessel size: The treatment may include the following steps: After ligation of the distal end of the gold tube, the gold tube is cut; the catheter (20) is implanted' and the position of the catheter (2〇) is determined by a mobile calender; 0) Poor position or duct (2 〇) is not well placed; cl.

In summary, first of all, the injection seat in the present creation has a reinforced injection top surface as well as a reinforced injection side, and the reinforced injection side means that more injection holes are opened on the side of the injection body. 'And the side of the reinforced injection is located on the other side of the connecting catheter side, thereby effectively facilitating the path of the wire A catheter, effectively solving the small diameter of the patient's blood vessel or the angle of the tube. In the larger case, it is not a problem to implant people. Secondly, the creation of the injection sheath has a side-opening design, so that the metal wire can be directly placed on the wire, and it is not necessary to find the end opening of the injection, as well as accurately aiming at it. - The end is open to allow the metal wire to enter the injection. Furthermore, the design of the body through the material tube system and the injection seat body can effectively strengthen the structural strength of the human vascular injection seat, and the problem of improving the connection between the conventional catheter sheath and the injection seat is relatively fragile. . The preceding paragraphs are specific to the technical essays of the above-mentioned (4); however, those who are familiar with the technology can change and modify the creation without departing from the spirit of this creation.
