Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a precise emergency arterial rupture rapid flow diversion device. Background Art

[0002] Arteries start from the heart, branch out to form arterioles, and finally terminate in capillaries in the tissues. The arterial wall is thicker, contains more elastic fibers, and has a round cross-section, which has certain contractility and elasticity. These characteristics enable the artery to produce a noticeable pulsation with the contraction of the heart and the level of blood pressure. Common external injuries such as car accidents, falls, and collisions may cause damage to the arterial wall, leading to arterial rupture. In addition, if you do not pay attention to protecting your body or over-exercise during sports, travel and other activities, your artery may also rupture. Arterial rupture is a serious medical emergency that requires prompt diagnosis and treatment.

[0003] After an artery ruptures, it is usually necessary to use a medical device such as a vascular sheath to perform vascular grafting with the assistance of angiography. However, when a major car accident occurs and there are many patients in the emergency department, there may not be enough medical equipment to assist doctors in examinations, and time is very tight. Traditional first aid measures, such as tourniquets to block blood flow, can temporarily stop bleeding, but will block blood supply to distal target organs, leading to serious complications and even amputation or death. Therefore, there is an urgent need for a device that can quickly stop bleeding while ensuring blood supply to distal target organs. The present invention provides a precise emergency arterial rupture rapid diversion device, which aims to solve this problem. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a precise emergency arterial rupture rapid diversion device, which guides an outer tube into the artery through a puncture needle, connects two corresponding outer tubes to form a temporary rapid diversion device, and provides time for subsequent rescue. At the same time, a tapered tube is added to the end of the outer tube of the blood diversion device to make its front end sharper and easier to penetrate the blood vessel wall, thereby improving the success rate of puncture. When the tapered tube is inserted into the blood vessel, its gradually expanding shape can gradually disperse the pressure on the blood vessel wall and reduce damage to the blood vessel wall. A one-way valve is added to the inside of the outer tube to ensure that blood can only flow in a predetermined direction, avoid damage caused by backflow, reduce the formation of thrombus, reduce unnecessary resistance and energy loss, improve the efficiency of blood diversion, and ensure sufficient blood supply to the target tissue or organ.

[0020] 2. The present invention provides a precise emergency arterial rupture rapid diversion device, which can reduce the blood flow rate in the area by arranging a squeezing device to compress the ruptured blood vessel. After the blood vessel is compressed, blood accumulates and swells, making the target blood vessel more prominent relative to the surrounding tissue. While reducing blood loss, the recognition of the blood vessel is improved, and it is easier for doctors to identify and locate the target blood vessel during surgery, thereby improving the accuracy of the diversion device insertion. At the same time, the stable compression force provided by the squeezing device can reduce the mobility of the blood vessel, making the insertion of the puncture needle more stable and reliable.

[0030] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] Example 1

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6, a precise emergency arterial rupture rapid diversion device, comprising two puncture needles 1, one end of the puncture needle 1 is connected to a pinching piece 2, the outside of the puncture needle 1 is provided with a diversion assembly 3, the diversion assembly 3 comprises an outer tube 31, one end of the outer tube 31 is connected to a conical tube 32, the inner part of the outer tube 31 is connected to a conical hose 35 and a conical fixing piece 37. A conical groove 36 is provided at one end of the conical hose 35, and the conical fixing piece 37 is embedded in the conical groove 36. A circular ring 38 is connected to the inner part of the conical hose 35, and a liquid pipe 39 is connected to the other side of the conical hose 35. The other end of one of the outer tubes 31 is connected to an external threaded ring 33, and the other end of the other outer tube 31 is connected to an internal threaded ring 34, and the external threaded ring 33 is threadedly connected to the internal threaded ring 34. By using the connecting assembly 4, we can apply pressure on both ends of the patient's arterial rupture position to cause the artery to swell, thereby assisting doctors to quickly and accurately identify the arterial puncture point. Then, the puncture needle 1 is inserted into the patient's artery, and the outer tube 31 is simultaneously pushed into the artery. Due to the narrow end design of the tapered tube 32, it fits more closely with the puncture needle 1, making it easier to enter the artery. After the initial puncture is completed, the puncture needle 1 can be easily withdrawn from the artery by pinching the pinching piece 2.

[0033] Next, two types of puncture needles 1 (such as Figure 1 As shown in the figure, the two outer tubes 31 have different external connectors after entering the artery: one end of one outer tube 31 is connected to the external threaded ring 33, while the other end is connected to the internal threaded ring 34. When in use, special attention should be paid to placing the outer tube 31 connected to the external threaded ring 33 on the upstream side of the artery, while the outer tube 31 connected to the internal threaded ring 34 is placed on the downstream side. Such a layout ensures that the conical hose 35 is connected to the inside of the outer tube 31 in the same direction.

[0034] When the outer threaded ring 33 is successfully connected to the inner threaded ring 34, the arterial blood will flow back to the artery through the conical hose 35 inside the outer tube 31, thereby avoiding the ruptured position. In the process of blood flowing through the conical hose 35, the conical fixing member 37 (made of a relatively hard material) connected in the conical groove 36 ensures that the blood can only flow from upstream to downstream to prevent backflow. In addition, a ring 38 is set at the circulation point inside the conical hose 35. When the blood is transferred from one side of the conical groove 36 to the side of the normal cylindrical liquid tube 39, the blood flows smoothly; but if blood backflow occurs, the liquid tube 39 will contract and deform, blocking the inside of the ring 38, effectively preventing blood backflow and reducing the formation of thrombus.

[0035] Finally, to ensure that the fast circulation device is installed firmly, the Velcro sub-surface 46 connected to the surface of the outer tube 31 needs to be tightly adhered to the Velcro main surface 45 to prevent the circulation device from moving during use.

[0036] Preferably, a connecting assembly 4 is provided at the bottom of the flow transfer assembly 3, and the connecting assembly 4 includes a soft air tube 41, and both ends of the soft air tube 41 are connected to connecting rods 42, one end of one of the connecting rods 42 is connected to a threaded rod 43, and one end of the other connecting rod 42 is provided with a threaded groove 44. The threaded rod 43 is threadedly connected to the inner wall of the threaded groove 44, and a connecting rope 47 is connected to the middle of the soft air tube 41. The middle of the soft air tube 41 is connected with a Velcro mother surface 45, and the top of the Velcro mother surface 45 is provided with a Velcro sub-surface 46, and the Velcro sub-surface 46 is sleeved on the middle of the outer tube 31. An extrusion component 5 is installed on one side of the connection component 4; the extrusion component 5 includes an air inlet pipe 51, the top of the air inlet pipe 51 is connected with an air cylinder 52, the bottom end of the air inlet pipe 51 is connected to the middle of the soft air tube 41, the air inlet pipe 51 is connected to the inside of the soft air tube 41, and the top and bottom ends of the air cylinder 52 are both provided with through holes 53, and the inside of the through hole 53 is connected with a one-way valve 56. The inside of the through hole 53 located at the top is connected with a fixing ring 54, and the inside of the fixing ring 54 is connected with a dustproof net 55. Before the puncture operation, the two soft air tubes 41 need to be properly surrounded on both sides of the patient's arterial rupture point. By tightening the threaded rod 43 and the threaded groove 44, we can firmly fix the soft air tube 41 on one side of the arterial rupture point and slightly squeeze the position to slow down the blood flow. It is worth noting that the soft air tube 41 is available in different sizes to meet the specific needs of different patients, so when using it, the most suitable size should be selected according to the actual situation for wrapping and fixing.

[0037] After the soft air tube 41 is fixed, the inflation operation is performed next. By pressing the air cylinder 52, the one-way valves 56 at both ends ensure that the gas can only enter the air inlet pipe 51 from one end of the dustproof net 55, and then enter the inside of the soft air tube 41. The dustproof net 55 plays a key role here. It can effectively filter the gas entering the air cylinder 52 and prevent the one-way valve 56 from being blocked. As the soft air tube 41 gradually inflates and swells, they exert greater squeeze on both ends of the arterial rupture point, causing blood flow to almost stagnate and causing the artery to swell significantly. This change greatly facilitates doctors to perform precise punctures and speeds up the installation process of the diversion device.

[0038] After the bypass device is installed, we pull the air inlet pipe 51 hard and easily remove it from one side of the soft air tube 41. This step causes the gas inside the soft air tube 41 to be released, thereby reducing the huge squeeze on both ends of the patient's arterial rupture point. Despite this, the soft air tube 41 still maintains a certain slight pressure, ensuring that the arterial blood flow rate is moderately reduced without affecting the patient's life safety, reducing the bypass pressure of the bypass device. This design not only ensures the patient's life safety, but also wins valuable time for subsequent treatment.

[0039] The use process of the precise emergency arterial rupture rapid diversion device provided by the present invention is as follows: use the connecting component 4 to compress the two ends of the patient's arterial rupture position to cause the patient's artery to swell, helping the doctor to quickly and accurately locate the arterial puncture point, puncture the puncture needle 1 into the patient's artery, and at the same time push the outer tube 31 into the patient's artery. The narrow end of the tapered tube 32 has a smaller area, fits more closely with the puncture needle 1, and is easier to enter the artery. Pinch the pinching piece 2 to remove the puncture needle 1 from the patient's artery position, and insert the two puncture needles shown in Figure 1 into the two ends of the arterial rupture position. Needle 1, after the two outer tubes 31 enter the patient's artery, the connectors remaining outside are different, that is, one end of one outer tube 31 is connected to the external threaded ring 33, and one end of the other outer tube 31 is connected to the internal threaded ring 34. When using, please note that the outer tube 31 connected to the external threaded ring 33 is located upstream of the artery, and the position connected to the internal threaded ring 34 is located downstream of the artery, so that the conical hose 35 connected to the inside of the outer tube 31 can be guaranteed to be in the same direction. After the external threaded ring 33 is connected to the internal threaded ring 34, the arterial blood returns to the artery through the conical hose 35 inside the outer tube 31. Avoid the rupture position. When the blood passes through the conical hose 35, the conical fixing piece 37 connected inside the conical groove 36 allows the blood to flow from upstream to downstream, but it cannot flow back because the conical fixing piece 37 is supported by a relatively hard material and cannot be deformed in the reverse direction. At the same time, a ring 38 is provided at the flow point inside the conical hose 35. When the blood is transmitted from one side of the conical groove 36 to the other side of the liquid tube 39, the liquid tube 39 is a normal cylindrical shape. However, when the blood flows back, the liquid tube 39 contracts and deforms, blocking the inside of the ring 38, thereby avoiding blood backflow and reducing the formation of thrombus. At the same time, when the rapid flow device After installation, it is also necessary to stick and fix the Velcro sub-surface 46 and the Velcro main surface 45 connected on the surface of the outer tube 31 to prevent the flow device from moving; before puncture, the two soft air tubes 41 are respectively wrapped around the two sides of the patient's arterial rupture point, so that the threaded rod 43 and the threaded groove 44 are interconnected, so as to fix the soft air tube 41 on one side of the arterial rupture point, and slightly squeeze the two sides of the rupture position to slow down the blood flow rate. The soft air tube 41 has different sizes, and the appropriate size should be selected according to needs. After the soft air tube 41 is wrapped around one side of the patient's arterial rupture point, the position is slightly squeezed. After the soft air tube 41 is fixed, press the air cylinder 52. Both ends of the air cylinder 52 are connected to a one-way valve 56, so that the gas can only enter the interior of the air inlet pipe 51 through one end of the dustproof net 55, and then enter the interior of the soft air tube 41, so that the soft air tube 41 is inflated and swollen. The dustproof net 55 can filter the gas entering the air cylinder 52 to avoid blockage of the one-way valve 56. After the soft air tube 41 is inflated and swollen, a greater squeeze is exerted on both ends of the arterial rupture point, thereby almost stopping the blood flow and causing the artery to swell, making it easier for the doctor to perform accurate puncture and quickly complete the installation of the diversion device.After the shunt device is installed, pull the air inlet pipe 51 hard to remove it from one side of the soft air tube 41, so that the gas inside the soft air tube 41 can be released. It no longer exerts huge squeezing on both ends of the patient's arterial rupture point, but still has a slight pressure. Without affecting the patient's life safety, the patient's arterial blood flow rate is slightly reduced, the shunt pressure of the shunt device is reduced, and at the same time the patient's life is protected, providing more time for subsequent treatment.
