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 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 slower. In some cases, the dosage of the drug will be increased to ensure the effect of the drug application, but some drugs have special properties. If they are not well grasped, they may cause adverse reactions, especially In the direct administration of drugs in blood vessels, the increase of the amount of drugs sometimes increases the risk of adverse reactions, so we propose an interventional therapy device for cardiovascular

Embodiment 1

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

Embodiment 2

[0031] In the second embodiment, in order to make the sealing ring 4 seal a certain section of blood vessels better and reduce the influence of blood flow on the diffusion of drugs, on the basis of the first embodiment, components such as the rotating block 10 are added, and the sealing ring 4 is close to the tapered sleeve. One end of 3 is provided with a plurality of turning blocks 10, and the turning blocks 10 are connected to the inside of the turning groove 9 through rotating shafts, and the turning groove 9 is opened on the side wall of the tapered sleeve 3, when the inner tube 1 is pulled to make the inner 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 rotary block 10 will rotate inside the corresponding rotary groove 9, and the sealing ring 4 is connected to the end of the rotary block 10 after turning a certain angle. The end stops sliding on the tapered sleeve 3, and the sealing ring 4 is cur...

Embodiment 3

[0033] Embodiment 3, since the device will form a relatively closed channel when in use, if the drug is injected directly and quickly, it may cause pressure and damage to the blood vessel wall, so it is best to extract the blood in the closed channel first, and then Injecting medicine, but the operation of replacing the syringe after extraction is cumbersome, and the risk of contamination is increased due to the increase of steps. Therefore, the syringe can be used to contain the first needle tube 17 based on the technology of embodiment 1 or embodiment 2. and the second needle tube 20, the syringe scheme in which the first needle tube 17 and the inner tube 1 are movably socketed, the material of the first needle tube 17 is a transparent material, and a cavity 18 is opened inside the first needle tube 17, and the cavity Two annular grooves 19 are formed on the inner side wall of the cavity 18, and an annular block 21 is slidably connected to the inside of the two annular groove...

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.
