Description

A precise emergency rapid diversion device for arterial rupture Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a precise emergency arterial rupture rapid diversion device. Background Technology

[0002] Arteries originate from the heart, branching into arterioles and ultimately terminating in capillaries within tissues. Arteries have thick walls, numerous elastic fibers, and a circular cross-section, exhibiting a degree of contractility and elasticity. These characteristics allow arteries to pulsate noticeably in response to heart contractions and fluctuations in blood pressure. Common external injuries such as car accidents, falls, and impacts can damage the arterial walls, leading to arterial rupture. Furthermore, improper physical protection or overexertion during sports activities or travel can also cause arterial rupture. Arterial rupture is a serious medical emergency requiring rapid diagnosis and treatment.

[0003] After an artery ruptures, medical devices such as vascular sheaths are typically used to repair and reconstruct the blood vessel with the aid of angiography. However, in major disasters such as car accidents, a large number of seriously injured people often occur. The accident scene or nearby may lack sufficient medical equipment and resources to assist doctors in performing complex vascular reconstruction, and time is extremely limited. Traditional first aid measures, such as tourniquets to stop blood flow, while temporarily stopping the bleeding, can block blood supply to distal target organs, leading to serious complications, 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. Summary of the Invention

[0004] Therefore, it is necessary to provide a precise emergency arterial rupture rapid diversion device to address the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precise emergency arterial rupture rapid diversion device includes two puncture needles and a diversion assembly. One end of each puncture needle is connected to a pinching element, and the diversion assembly is disposed outside the puncture needle. A connecting component is disposed at the bottom of the diversion assembly, and a squeezing component is installed on one side of the connecting component. The diversion assembly includes an outer tube, one end of which is connected to a tapered tube, and the inside of the outer tube is connected to a tapered flexible tube and a tapered fixing element.

[0007] As some preferred embodiments of the present invention, one end of the tapered hose is provided with a tapered groove, and the tapered fixing member is embedded in the inside of the tapered groove.

[0008] As some preferred embodiments of the present invention, the conical hose has an internal ring connected to it, and the other side of the conical hose is connected to a liquid tube.

[0009] As some preferred embodiments of the present invention, the flow conversion assembly includes two corresponding outer tubes, one of which is connected to an external threaded ring at one end, and the other of which is connected to an internal threaded ring at the other end, wherein the external threaded ring and the internal threaded ring are threadedly connected.

[0010] As some preferred embodiments of the present invention, the connecting assembly includes a flexible air tube, both ends of which are connected to connecting rods. One end of one of the connecting rods is connected to a threaded rod, and the other end of the connecting rod has a threaded groove.

[0011] As some preferred embodiments of the present invention, the threaded rod is threadedly connected to the inner wall of the threaded groove, and a connecting rope is connected to the middle of the flexible air tube.

[0012] As some preferred embodiments of the present invention, the middle part of the flexible tube is connected to a Velcro female surface, the top of the Velcro female surface is provided with a Velcro male surface, and the Velcro male surface is sleeved on the middle part of the outer tube.

[0013] As some preferred embodiments of the present invention, the extrusion assembly includes an air inlet pipe, the top of which is connected to an air cylinder, the bottom of which is connected to the middle of the flexible air tube, and the air inlet pipe communicates with the interior of the flexible air tube.

[0014] As some preferred embodiments of the present invention, the top and bottom ends of the air cylinder are provided with through holes, and a one-way valve is connected inside the through holes.

[0015] As some preferred embodiments of the present invention, a fixing ring is connected inside the through hole at the top of the air cylinder, and a dustproof net is connected inside the fixing ring.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This invention provides a precise emergency arterial rupture rapid diversion device. An outer tube is guided into the artery via a puncture needle. Two corresponding outer tubes are connected to form a temporary rapid diversion device, providing time for subsequent rescue. A tapered tube is added to the end of the outer tube of the blood diversion device, making its tip 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, reducing damage. Furthermore, a one-way valve is added inside the outer tube to ensure that blood flows only in the predetermined direction, avoiding damage caused by backflow, reducing thrombus formation, minimizing unnecessary resistance and energy loss, improving the efficiency of blood diversion, and ensuring sufficient blood supply to the target tissue or organ.

[0018] 2. The present invention provides a precise emergency arterial rupture rapid diversion device. By setting a compression device to compress the ruptured blood vessel, the blood flow rate at that location can be reduced. 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 identification of the blood vessel is improved, making it 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 compression device can reduce the mobility of the blood vessel, making the insertion of the puncture needle more stable and reliable.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0028] Example 1

[0029] Please refer to Figures 1, 2, 3, 4, 5, and 6. A precise emergency arterial rupture rapid diversion device 100 includes two puncture needles 1. One end of each puncture needle 1 is connected to a pinch element 2. A diversion assembly 3 is disposed outside the puncture needles 1. The diversion assembly 3 includes an outer tube 31, one end of which is connected to a tapered tube 32. A tapered flexible tube 35 and a tapered fixing element 37 are connected inside the outer tube 31. One end of the tapered flexible tube 35 has a tapered groove 36 coaxial with the tapered flexible tube 35, and the tapered fixing element 37 is embedded inside the tapered groove 36. A circular ring 38 is connected inside the tapered flexible tube 35, and a fluid tube 39 is connected to the other side of the tapered flexible tube 35. The diversion assembly 3 includes two outer tubes 31, with tapered tubes 32 disposed at their respective far ends, and puncture needles 1 disposed at their respective far ends. The two adjacent ends of the two outer tubes 31 are detachably connected. One end of one outer tube 31 (opposite to the aforementioned "one end") is connected to an external threaded ring 33, and the other end of the other outer tube 31 (opposite to the aforementioned "one end") is connected to an internal threaded ring 34. The external threaded ring 33 and the internal threaded ring 34 are threadedly connected. By using the connecting assembly 4, pressure can be applied to both ends of the ruptured artery, causing the artery to swell, thereby assisting the doctor in quickly and accurately identifying the arterial puncture point. Subsequently, the puncture needle 1 is inserted into the patient's artery, and the outer tube 31 is simultaneously advanced into the artery. Due to the narrow end design of the tapered tube 32, it fits more tightly with the puncture needle 1, facilitating smooth entry into the artery. After the initial puncture is completed, the puncture needle 1 can be easily withdrawn from the artery by pinching the pinch element 2.

[0030] Next, two types of puncture needles 1 are inserted at both ends of the artery rupture site (as shown in Figure 1), ensuring that the external connectors of the two outer tubes 31 differ after entering the artery: one outer tube 31 is connected to an external threaded ring 33 at one end, while the other is connected to an internal threaded ring 34. During use, special care must be taken to place the outer tube 31 connected to the external threaded ring 33 upstream of the artery, while the outer tube 31 connected to the internal threaded ring 34 is placed downstream. This arrangement ensures that the tapered flexible tube 35 is connected to the inside of the outer tube 31 in the same direction.

[0031] Once the external threaded ring 33 and the internal threaded ring 34 are successfully connected, arterial blood will flow back into the artery through the tapered flexible tube 35 inside the outer tube 31, thus avoiding the rupture site. During the flow of blood through the tapered flexible tube 35, the tapered fixing member 37 (made of a relatively rigid material) connected within the tapered groove 36 ensures that blood can only flow from upstream to downstream, preventing backflow. Furthermore, a circular ring 38 is provided at the flow point inside the tapered flexible tube 35. When blood is transferred from one side of the tapered groove 36 to the other side of the normal cylindrical liquid tube 39, the flow is smooth; however, if backflow occurs, the liquid tube 39 will contract and deform, blocking the inside of the circular ring 38, effectively preventing backflow and reducing thrombus formation.

[0032] Finally, to ensure the rapid transfer device is installed securely, the Velcro side 46 and the Velcro side 45 of the outer tube 31 must be tightly glued together to prevent the transfer device from moving during use.

[0033] In some embodiments, a connecting component 4 is provided at the bottom of the diversion assembly 3. The connecting component 4 includes a flexible air tube 41, with connecting rods 42 connected to both ends of the flexible air tube 41. One end of one connecting rod 42 is connected to a threaded rod 43, and the other end of the connecting rod 42 has a threaded groove 44. The threaded rod 43 is inserted into the threaded groove 44 and threadedly connected to the inner wall of the threaded groove 44. A connecting rope 47 is connected to the middle of the flexible air tube 41. A hook and loop fastener face 45 is connected to the middle of the flexible air tube 41, and a hook and loop fastener face 46 is provided on the top of the hook and loop fastener face 45. The hook and loop fastener face 46 is fitted onto the middle of the outer tube 31. A compression assembly 5 is installed on one side of the connecting assembly 4. The compression assembly 5 includes an air inlet tube 51, with an air cylinder 52 connected to the top of the air inlet tube 51 and the bottom end of the air inlet tube 51 connected to the middle of the flexible air tube 41. The air inlet tube 51 and the flexible air tube 41 are internally connected. Both the top and bottom ends of the air cylinder 52 have through holes 53, and a one-way valve 56 is connected inside the through hole 53. A fixing ring 54 is connected inside the through hole 53 at the top, and a dustproof net 55 is connected inside the fixing ring 54. Before the puncture operation, the two flexible air tubes 41 need to be properly wrapped around both sides of the patient's arterial rupture point. By tightening the threaded rod 43 and the threaded groove 44 together, the flexible air tube 41 can be firmly fixed to one side of the arterial rupture point, and a slight compression is applied to this position to slow down the blood flow. It is worth noting that the soft trachea 41 is available in different sizes to meet the specific needs of different patients (for example, the diameter of the ring structure formed by soft trachea 41 of different lengths is different, which can adapt to the circumference of different bleeding locations). Therefore, when using it, the most appropriate size should be selected for wrapping and fixation according to the actual situation.

[0034] After the flexible tubing 41 is secured, inflation is performed. By pressing the air cylinder 52, the one-way valves 56 at both ends ensure that gas can only enter the inlet tube 51 through the dust filter 55 end, and then into the flexible tubing 41. The dust filter 55 plays a crucial role here, effectively filtering the gas entering the air cylinder 52 and preventing the one-way valves 56 from becoming blocked. As the flexible tubing 41 gradually inflates and swells, it applies greater pressure to both ends of the arterial rupture point, causing blood flow to almost stop and the artery to swell significantly. This change greatly facilitates precise puncture by the physician and accelerates the installation process of the bypass device.

[0035] After the shunt device was installed, we pulled the inlet tube 51 forcefully to easily remove it from one side of the flexible endotracheal tube 41. This step caused the gas inside the flexible endotracheal tube 41 to be released, thereby reducing the enormous pressure on both ends of the patient's arterial rupture point.

[0036] Nevertheless, the soft trachea 41 maintains a certain level of slight pressure to ensure that the arterial blood flow velocity is moderately reduced without compromising the patient's life, thereby alleviating the pressure on the bypass device. This design not only safeguards the patient's life but also buys valuable time for subsequent treatment.

[0037] The procedure for using the precise emergency arterial rupture rapid diversion device provided by this invention is as follows: Using the connecting component 4, pressure is applied to both ends of the patient's arterial rupture site to cause swelling of the artery, helping the doctor to quickly and accurately locate the arterial puncture point. The puncture needle 1 is then inserted into the patient's artery, while the outer tube 31 is pushed into the patient's artery. The narrow end of the tapered tube 32 has a smaller area, allowing for a tighter fit with the puncture needle 1 and easier entry into the artery. The puncture needle 1 is removed from the patient's artery by pinching the gripper 2. The two types of puncture needles 1 shown in Figure 1 are then inserted into both ends of the arterial rupture site. The two outer tubes 31 have different external connectors after entering the patient's artery. One outer tube 31 is connected to an external threaded ring 33 at one end, and the other outer tube 31 is connected to an internal threaded ring 34 at one end. During use, it is important to ensure that the outer tube 31 connected to the external threaded ring 33 is positioned upstream of the artery, and the outer tube 31 connected to the internal threaded ring 34 is positioned downstream. This ensures that the tapered flexible tube 35 connected inside the outer tube 31 faces the same direction. After connecting the external threaded ring 33 and the internal threaded ring 34, arterial blood returns to the artery through the tapered flexible tube 35 inside the outer tube 31, avoiding... At the rupture site, as blood flows through the conical hose 35, the conical fixing member 37 connected inside the conical groove 36 allows blood to flow from upstream to downstream, but not backwards. This is because the conical fixing member 37 is made of a relatively rigid material and cannot deform in the opposite direction. Simultaneously, a ring 38 is installed at the flow point inside the conical hose 35. When blood is transferred 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 blood flows backwards, the liquid tube 39 contracts and deforms, blocking the interior of the ring 38, thereby preventing blood backflow and reducing thrombus formation. Simultaneously, when the rapid flow device is installed... After installation, the Velcro side 46 of the outer tube 31 and the Velcro side 45 need to be glued and fixed to prevent the transfer device from moving. Before puncture, the two soft tubes 41 are wrapped around both sides of the patient's arterial rupture point, so that the threaded rod 43 and the threaded groove 44 are connected to each other, thereby fixing the soft tube 41 to one side of the arterial rupture point. Slightly squeeze both sides of the rupture point to slow down the blood flow. The soft tubes 41 have different sizes, and the appropriate size should be selected according to the needs. After the soft tube 41 is wrapped around one side of the patient's arterial rupture point, slight pressure is applied to the position. After the flexible tubing 41 is fixed in place, press the air cylinder 52. Both ends of the air cylinder 52 are connected to one-way valves 56, allowing gas to enter the interior of the air inlet tube 51 only through the dustproof net 55, and then into the interior of the flexible tubing 41, causing the flexible tubing 41 to inflate and swell. The dustproof net 55 can filter the gas entering the air cylinder 52, preventing the one-way valves 56 from becoming blocked. After the flexible tubing 41 is inflated and swelled, it exerts greater pressure on both ends of the artery rupture point, thereby almost stopping blood flow and causing the artery to swell, making it easier for doctors to perform precise punctures and quickly complete the installation of the bypass device.After the bypass device is installed, pull the inlet tube 51 forcefully to remove it from one side of the flexible tube 41, allowing the gas inside the flexible tube 41 to be released. This will stop the huge compression on both ends of the patient's arterial rupture point, but will still maintain a slight pressure. Without affecting the patient's life safety, this will slightly reduce the patient's arterial blood flow velocity, reduce the bypass pressure of the bypass device, and at the same time protect the patient's life, providing more time for subsequent treatment.
