Problems solved by technology

[0002] Cardiovascular interventional therapy is a new technology for diagnosing and treating cardiovascular diseases. Under the guidance of imaging methods, through puncture of blood vessels on the surface of the body, with the help of guide wires and other instruments, the catheter is sent to the diseased part of the cardiovascular system. It is a diagnosis and treatment method for the diagnosis and treatment of cardiovascular disease. When ordinary cardiovascular interventional therapy devices inject drugs into the diseased cardiovascular site, due to the blood circulation inside the cardiovascular system, the

Example Embodiment

[0030] In the first embodiment, the present invention provides an interventional therapy device for cardiovascular disease, comprising an inner tube 1, a through hole 6 and a threading hole 26 are opened inside the inner tube 1, and the side wall of the through hole 6 is The position between the two sealing rings 4 is provided with a through-liquid hole 601 communicating with the outside, so as to facilitate the injection of medicines. The threading hole 26 is provided with a guide wire 27 inside, and the through hole 6 is a cavity for medicine injection and blood drawing. , The end of the through hole 6, that is, the position of the through hole 601 is between the two tapered sleeves 3. When using this device, the guide wire 27 is pre-placed inside the human blood vessel to reach the cardiovascular part where the disease needs to be treated. Let the device follow the guide wire 27 gradually to reach the designated position. Two tapered sleeves 3 are sleeved on the outer side wa...

Example Embodiment

[0031] In the second embodiment, in order to make the sealing ring 4 better seal a certain section of the blood vessel and reduce the influence of blood flow on the diffusion of the drug, on the basis of the first embodiment, a rotating block 10 and other components are added, and the sealing ring 4 is close to the conical sleeve A plurality of rotating blocks 10 are provided at one end of 3, and the rotating blocks 10 are rotatably connected to the inside of the rotating groove 9 through a rotating shaft. The rotating groove 9 is opened on the side wall of the tapered sleeve 3. When the inner tube 1 is pulled, the inner tube When the tube 1 slides inside the outer tube 2, the sealing ring 4 slides on the tapered sleeve 3, and at the same time the rotating block 10 will rotate inside the corresponding rotating groove 9. After a certain angle, the sealing ring 4 is connected to the end of the rotating block 10 The part stops sliding on the tapered sleeve 3, and the sealing ring 4...

Example Embodiment

[0033] The third embodiment, because the device will form a relatively closed channel when in use, if the drug is injected directly and quickly, it may cause pressure damage to the blood vessel wall. Therefore, it is best to draw the blood in the closed channel first, and then Injecting drugs, but replacing the syringe after extraction for injection is cumbersome and increases the risk of contamination due to increased steps. Therefore, in the technology of Embodiment 1 or Embodiment 2, the syringe can be used to include the first needle tube 17 And the second needle tube 20, the first needle tube 17 is movably sleeved with the inner tube 1, the material of the first needle tube 17 is a transparent material, the first needle tube 17 has a cavity 18 inside, and the hollow The inner side wall of the cavity 18 is provided with two annular grooves 19, and the inside of the two annular grooves 19 are slidably connected with an annular block 21. The annular block 21 is provided on the...

Abstract

The invention discloses an interventional therapy apparatus used for cardiovascular diseases. The interventional therapy apparatus comprises an inner tube. The interior of the inner tube is equipped with a through hole and a wire penetrating hole. A guide wire is arranged in the interior of the wire penetrating hole. Tapered sleeves are connected through connection columns. The interiors of the connection columns are all equipped with drainage chambers. One end of the inner tube is movably connected with a first needle tube. A cavity is arranged in the interior of the first needle tube. An annular groove is arranged in the cavity. By the pulling the inner pipe, two sealing rings are supported by extrusion. Therefore, heart and blood vessels at the connection columns are separated from those at other parts. At this time, blood at a cardiovascular diseased position remains stationary. Then, medicine is injected to blood at cardiovascular diseased position through the through hole. The medicine stays at the cardiovascular diseased position, thereby effectively reducing the medicine applying amount. The risk due to excessively great amount of medicine application is minimized. Additionally, in the manner of dual injection cavities, pressure build-up caused by medicine injection is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an interventional treatment device for cardiovascular. Background technique [0002] Cardiovascular interventional therapy is a new technology for diagnosing and treating cardiovascular diseases. Under the guidance of imaging methods, through puncture of blood vessels on the surface of the body, with the help of guide wires and other instruments, the catheter is sent to the diseased part of the cardiovascular system. It is a diagnosis and treatment method for the diagnosis and treatment of cardiovascular disease. When ordinary cardiovascular interventional therapy devices inject drugs into the diseased cardiovascular site, due to the blood circulation inside the cardiovascular system, the injected drugs will flow with the blood and will not be in the area of ​​cardiovascular disease. Therefore, the effect of the drug will be reduced and the recovery of the patient will be...
