Description

Technical Field

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

[0002] Arteries originate from the heart, continuously branch to form arterioles, and finally terminate at the capillaries in tissues. The arterial wall is relatively thick, with more elastic fibers, and the cross-section of the lumen is circular, having a certain contractility and elasticity. These characteristics enable the arteries to produce obvious pulsations along with the contraction of the heart and the level of blood pressure. Common external injuries such as car accidents, falls, and impacts may cause damage to the arterial wall, leading to arterial rupture. In addition, when engaging in activities such as sports and tourism, if one does not pay attention to protecting the body or exercises excessively, arterial rupture may also occur. Arterial rupture is a serious medical emergency that requires prompt diagnosis and treatment.

[0003] After arterial rupture, medical devices such as vascular sheaths are usually required 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 devices to assist doctors in examinations, and the time is extremely urgent. Traditional first-aid measures, such as using a tourniquet to block blood flow, although can stop bleeding temporarily, will block the blood supply to the distal target organs, leading to serious complications, or even amputation or death. Therefore, there is an urgent need for a device that can ensure the blood supply to the distal target organs while quickly stopping bleeding. The present invention provides a precise emergency arterial rupture rapid bypass device to address this problem. Summary of the Invention

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

[0019] 1.

[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 solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6, A precise emergency arterial rupture rapid bypass device, including two puncture needles 1. One end of the puncture needle 1 is connected with a pinch piece 2. An external bypass component 3 is arranged outside the puncture needle 1. The bypass component 3 includes an outer tube 31. One end of the outer tube 31 is connected with a conical tube 32. Inside the outer tube 31, a conical flexible tube 35 and a conical fixing piece 37 are connected. One end of the conical flexible tube 35 is provided with a conical groove 36. The conical fixing piece 37 is embedded inside the conical groove 36. Inside the conical flexible tube 35, a circular ring 38 is connected. The other side of the conical flexible tube 35 is connected with a liquid tube 39. One end of the other outer tube 31 is connected with an external thread ring 33, and one end of the other outer tube 31 is connected with an internal thread ring 34. The external thread ring 33 is in threaded connection with the internal thread ring 34. By using the connection component 4, we can apply pressure at both ends of the arterial rupture position of the patient, prompting the artery to swell, so as to assist the doctor to quickly and accurately identify the arterial puncture point. Subsequently, insert the puncture needle 1 into the patient's artery, and simultaneously push the outer tube 31 into the artery. Due to the narrow end design of the conical tube 32, it fits more closely with the puncture needle 1, facilitating the smooth entry into the artery. After the initial puncture, by pinching the pinch piece 2, the puncture needle 1 can be easily withdrawn from the artery.

[0033] Next, insert two types of puncture needles 1 (as Figure 1 shown) at both ends of the arterial rupture position respectively, ensuring that after the two outer tubes 31 enter the artery, their external connectors are different: one end of one outer tube 31 is connected with an external thread ring 33, while the other is connected with an internal thread ring 34. During use, special attention should be paid to placing the outer tube 31 connected with the external thread ring 33 on the upstream side of the artery, and the outer tube 31 connected with the internal thread ring 34 on the downstream side. Such a layout ensures that the conical flexible tube 35 is connected inside the outer tube 31 in the same direction.

[0034] When the external thread ring 33 is successfully connected with the internal thread ring 34, the arterial blood will flow back into the artery through the conical flexible tube 35 inside the outer tube 31, thus avoiding the rupture position. During the process of blood flowing through the conical flexible tube 35, the conical fixing piece 37 (made of a relatively hard material) connected in the conical groove 36 ensures that the blood can only flow from the upstream to the downstream, preventing backflow. In addition, a circular ring 38 is arranged at the circulation part inside the conical flexible tube 35. When the blood is transmitted from one side of the conical groove 36 to the normal cylindrical liquid tube 39 side, the flow is smooth; but if blood backflows, the liquid tube 39 will contract and deform, blocking the inside of the circular ring 38, effectively preventing blood backflow and reducing the formation of blood clots.

[0035] Finally, to ensure the stable installation of the rapid bypass device, it is also necessary to closely paste the hook surface 46 connected to the surface of the outer tube 31 with the loop surface 45 to prevent the bypass device from moving during use.

[0036] Preferably, a connection component 4 is provided at the bottom of the bypass component 3. The connection component 4 includes a soft air tube 41. Both ends of the soft air tube 41 are connected with a connecting rod 42. One end of one of the connecting rods 42 is connected with a threaded rod 43, and a threaded groove 44 is provided at one end of the other connecting rod 42. The threaded rod 43 is in threaded connection with the inner wall of the threaded groove 44. A connecting rope 47 is connected to the middle of the soft air tube 41. A magic tape female surface 45 is connected to the middle of the soft air tube 41. A magic tape male surface 46 is provided on the top of the magic tape female surface 45. The magic tape male 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 with the middle of the soft air tube 41. The air inlet pipe 51 is internally communicated with the soft air tube 41. Through holes 53 are provided at the top end and the bottom end of the air cylinder 52. One-way valves 56 are connected inside the through holes 53. A fixing ring 54 is connected inside the through hole 53 at the top. A dust-proof net 55 is connected inside the fixing ring 54. Before the puncture operation, first, the two soft air tubes 41 need to be properly wound around both sides of the arterial rupture point of the patient. By screwing the threaded rod 43 and the threaded groove 44 tightly with each other, we can firmly fix the soft air tube 41 on one side of the arterial rupture point and apply a slight extrusion to this position to slow down the blood flow rate. It should be noted that the soft air tubes 41 are available in different sizes to meet the specific needs of different patients. Therefore, the most suitable size should be selected for winding and fixing according to the actual situation during use.

[0037] After the soft air tube 41 is fixed, the inflation operation is carried out next. By pressing the air cylinder 52, the one-way valves 56 equipped at both ends ensure that the gas can only enter the air inlet pipe 51 from the end of the dust-proof net 55 and then enter the inside of the soft air tube 41. The dust-proof 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 a greater extrusion on both ends of the arterial rupture point, resulting in the blood flow being almost stagnant and the artery swelling significantly. This change greatly facilitates the doctor to perform accurate puncture and accelerates the installation process of the bypass device.

[0038] After the bypass device is installed, we pull the air inlet pipe 51 forcefully 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 extrusion on both ends of the arterial rupture point of the patient. Nevertheless, the soft air tube 41 still maintains a certain slight pressure, ensuring that without affecting the patient's life safety, the arterial blood flow rate is moderately reduced and the bypass pressure of the bypass device is alleviated. This design not only guarantees the patient's life safety but also wins precious time for subsequent treatment.

[0039] The usage process of a precise emergency arterial rupture rapid bypass device provided by the present invention is as follows: Using the connection component 4, compress both ends of the arterial rupture position of the patient to cause swelling of the patient's artery, which helps the doctor quickly and precisely locate the arterial puncture point. Puncture the puncture needle 1 into the patient's artery. At the same time, push the outer tube 31 into the patient's artery. The narrow end of the conical tube 32 has a smaller area and fits more closely with the puncture needle 1, making it easier to enter the artery. Pinch the pinch piece 2 to remove the puncture needle 1 from the patient's artery position. Insert the two puncture needles 1 shown in the puncture needle 1 into both ends of the arterial rupture position respectively. 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 thread ring 33, and one end of the other outer tube 31 is connected to the internal thread ring 34. When using, it should be noted that the outer tube 31 connected to the external thread ring 33 is located upstream of the artery, and the position connected to the internal thread ring 34 is located downstream of the artery. In this way, it can be ensured that the conical flexible tube 35 connected inside the outer tube 31 is in the same orientation. After connecting the external thread ring 33 and the internal thread ring 34, the arterial blood re-enters the artery through the conical flexible tube 35 inside the outer tube 31, avoiding the rupture position. When the blood passes through the conical flexible tube 35, the conical fixing piece 37 connected inside the conical groove 36 enables the blood to flow from upstream to downstream, but cannot flow backward because the conical fixing piece 37 is supported by a relatively hard material and cannot undergo reverse deformation. At the same time, a circular ring 38 is provided at the flow-through part inside the conical flexible tube 35. When the blood is transmitted from one side of the conical groove 36 to the liquid tube 39 side, the liquid tube 39 is a normal cylindrical shape, but when the blood flows backward, the liquid tube 39 undergoes constriction deformation and blocks the inside of the circular ring 38, thereby preventing blood from flowing backward and reducing the formation of blood clots. At the same time, after the rapid bypass device is installed, it is also necessary to paste and fix the hook surface 46 connected to the surface of the outer tube 31 with the loop surface 45 to prevent the bypass device from moving; before puncture, respectively surround the two soft air tubes 41 around both sides of the arterial rupture point of the patient, and connect the threaded rod 43 with the thread groove 44 to fix the soft air tube 41 on one side of the arterial rupture point, and slightly squeeze both sides of the rupture position to slow down the blood flow rate. The soft air tubes 41 have different sizes, and appropriate sizes should be selected according to needs. After the soft air tube 41 surrounds one side of the arterial rupture point of the patient, it produces a slight squeeze on this position. After the soft air tube 41 is fixed, press the air cylinder 52. Both ends of the air cylinder 52 are connected with one-way valves 56, so that the gas can only enter the inside of the air inlet pipe 51 through the end with the dust-proof net 55, and then enter the inside of the soft air tube 41, making the soft air tube 41 inflate and swell. The dust-proof net 55 can filter the gas entering the air cylinder 52 to avoid blocking the one-way valve 56. After the soft air tube 41 inflates and swells, it produces a greater squeeze on both ends of the arterial rupture point, thereby making the blood almost stop flowing and the artery swell, facilitating the doctor to precisely perform puncture and quickly complete the installation of the bypass device.After the bypass device is installed, pull the intake pipe 51 forcefully to remove the intake pipe 51 from one side of the flexible pipe 41, so that the gas inside the flexible pipe 41 is released, and no longer exerts a huge extrusion on both ends of the patient's arterial rupture point, but still has a slight pressure. Without affecting the patient's life safety, the arterial blood flow rate of the patient is slightly reduced, the bypass pressure of the bypass device is slowed down, and at the same time, the patient's life is ensured, providing more time for subsequent treatment.
