Description

Technical Field

[0001] This invention relates to the fields of medical devices and information technology, specifically to a wound treatment device and method incorporating magnetically simulated blood vessels. Background Technology

[0002] Cardiovascular interventional surgery, as a core minimally invasive technique for treating cardiovascular diseases such as coronary heart disease, arrhythmia, and vascular stenosis, has been widely used in clinical practice worldwide due to its advantages of minimal trauma, rapid recovery, and definite efficacy. Currently, the mainstream clinical methods for hemostasis and rehabilitation fall into two main categories: one is traditional manual pressure combined with elastic bandage application, requiring medical staff to apply continuous pressure for 15-20 minutes, followed by bandage fixation for 2-4 hours; the other uses mechanical pressure devices (such as inflatable tourniquets or plastic compressors) in conjunction with bandage fixation, achieving hemostasis through continuous mechanical pressure on the incision. While both methods can achieve basic hemostasis, they share common drawbacks that are difficult to overcome: Severe discomfort caused by blood circulation blockage: During the compression process, the pressure of the bandage or mechanical device must completely block arterial blood flow to prevent bleeding from the incision. This reduces the blood perfusion of the tissues at the end of the arm to almost zero, which may lead to complications such as hematoma and pseudoaneurysm in severe cases.

[0003] Risk of complications from prolonged compression: High pressure compression for 2-4 hours can easily lead to problems such as local skin damage, nerve entrapment, and venous thrombosis, which in turn bring additional pain and medical burden to patients.

[0004] The contradiction between hemostasis and blood perfusion is difficult to balance: existing technologies cannot find a balance between effective hemostasis and maintaining peripheral blood flow. If the pressure is insufficient, arterial bleeding cannot be stopped; if the pressure is sufficient, peripheral ischemia will inevitably occur. Although some mechanical compression devices are designed with the function of "intermittent negative pressure drainage", the risk of incision bleeding increases during the decompression process, and the operation is cumbersome, requiring medical staff to monitor the process throughout, which consumes a lot of medical resources.

[0005] Low wound healing efficiency and long recovery period: Traditional pressure only relies on the blood vessel wall's own coagulation function and natural tissue healing, lacking a plan to actively promote healing. Moreover, due to damage to the endothelial cells of the blood vessel wall at the incision site and poor local blood circulation, complete healing after surgery usually takes 7-10 days. During this period, patients need to avoid strenuous activity of the operated limb, which will affect their normal life and work.

[0006] In addition, with the aging of the population, the proportion of special groups such as elderly patients, diabetic patients, and anticoagulant drug users is increasing year by year. These patients have poor vascular elasticity, weak coagulation function, and insufficient tissue repair ability. The risk of complications from traditional pressure methods is higher, and the requirements for the precision and safety of wound hemostasis and rehabilitation are more stringent. Summary of the Invention

[0007] The purpose of this invention is to provide a wound treatment device and method equipped with magnetic simulated blood vessels, which solves the technical problems of obstructed blood flow, single force, low healing efficiency, and lack of personalized treatment in the rehabilitation of existing cardiovascular interventional surgical wounds. It achieves effective blood flow under wound pressure, promotes wound healing through the synergistic effect of magnetic and mechanical forces, and establishes a systematic pathological analysis and personalized treatment system.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A wound treatment device equipped with a magnetic simulated blood vessel includes a simulated blood vessel component and a pressing device. The simulated blood vessel component is used to create a second micro-perforated wound, which is an intervention channel of the simulated blood vessel component. Preferably, its diameter is 1 / 3 or less of the surgical wound. The simulated blood vessel assembly includes an inner simulated blood vessel, which has a hollow channel structure and is divided into a front end, a wound end, a rear end, a new wound end, and a handle end along the axial direction. The rear end has a blood inlet micropore on its wall, and the front end is configured as a needle tip outlet or a smooth round opening. The handle end is sealed with a membrane, an internal plug, or equipped with a medical positive pressure connector. The pressing device consists of a knob, a spring, a support plate, and a pressing surface, arranged from top to bottom. A magnetic material is placed below the pressing surface, and a curved groove is formed in the middle. The depth of the curved groove is adjustable according to the location and severity of the wound. The curved groove can be one, multiple, or a combination of different widths, and is used in conjunction with the internal simulated blood vessel for pressing and positioning.

[0009] Furthermore, the blood inlet micropores are a combination of circular and elongated structures, wherein the number of elongated blood inlet micropores is 6 to 18 and the number of circular micropores is 6 to 36. The diameter, number, and arrangement of the micropores can be adjusted according to the blood inlet volume requirements.

[0010] Optionally, the pressing device may also employ a grooved miniature vascular clamp, which includes a vascular clamp arm, a second spring, a central rotating shaft, and a vascular clamp holding end; wherein, all / or the rear half of the vascular clamp holding end is provided with a magnet / other alloy material, and the inner surfaces on both sides of the vascular clamp holding end are provided with a soft rubber layer, the surface of the soft rubber layer being a corrugated shallow groove, and the groove of the grooved miniature vascular clamp cooperates with the inner simulated blood vessel for clamping.

[0011] Furthermore, the pressing device also includes a bandage with at least two pressure-dispersing tubes. The pressure-dispersing tubes and the bandage are connected by a sliding rail structure, which allows them to slide freely and be naturally fixed. Their position can also be adjusted by an adhesive adhesive patch. The bandage is configured as a single bandage, a double bandage, or a double screw fixing mode, and the end is fixed with adhesive or Velcro. The left side of the support plate is the movable end of the bandage, and the right side is the fixed end of the bandage. However, the structure and appearance of the left and right ends are not limited, and the position of the movable end can be changed according to the left or right hand or the injury situation.

[0012] Furthermore, the outer wall of the inner simulated blood vessel is provided with magnetic material / magnetic coating / magnetic film, preferably with magnetic coating on the outer wall.

[0013] Furthermore, the magnetic thin film is made of one or more of the following: nano-scale thin film material, medical shape memory metal, soft medical material, magnetic material, general medical material, or alloy material. The thickness is 0.05-0.10 mm by default, and its thickness and length and width dimensions can be adjusted according to the size of the wound.

[0014] Furthermore, a pressing soft rubber layer is provided under the magnetic material.

[0015] Preferably, the internal simulated blood vessel is an irregular simulated blood vessel, and a curved irregular structure is provided between the needle tip, front end, blood inlet micropore and the new wound end of the internal simulated blood vessel, wherein the bending angle is adjusted according to the wound, and the default bending angle α is less than 90°.

[0016] Furthermore, the outer diameter of the simulated blood vessel is 0.3mm to 1.27mm, and its inner and outer diameters can be adjusted according to the wound opening, which meets medical standards.

[0017] Furthermore, the simulated blood vessel assembly also includes an external simulated blood vessel, which is a tubular structure consisting of a bidirectional needle and an intermediate infusion tubing; one or more internal and external simulated blood vessels can be provided according to the wound treatment needs.

[0018] Furthermore, the wound treatment device equipped with magnetic simulated blood vessels also includes a background intelligent analysis system, which includes a large language model analysis module and a pathological reverse analysis module. The large language model analysis module is used to establish cardiovascular disease-related big data, covering information on race, age, gender, occupation, blood lipids, blood pressure, and cardiovascular-related indicators. The pathological reverse analysis module is used to generate personalized treatment plans and a real-time tracking and early warning system based on the big data.

[0019] A wound treatment method using a wound treatment device equipped with a magnetic simulated blood vessel includes the following steps: S1. After the vascular interventional procedure is completed, apply pressure to the blood supply end of the blood vessel to stop bleeding and clean the surgical wound; S2. A second micro-hole wound is created by directly inserting the internal simulated blood vessel with a needle-tip-shaped outlet at a suitable blood vessel site at the rear end of the surgical wound. A closed sterile adhesive tape is then attached to the outer skin of the second micro-hole wound. S3. Insert the internal simulated blood vessel into the human blood vessel through the second micro-hole incision, so that the incision end of the internal simulated blood vessel is basically aligned with the surgical incision, and the position of the new incision end is adapted to the second micro-hole incision. S4. Place the pressing device on the surgical wound so that the curved groove of the pressing device fits and is positioned with the inner simulated blood vessel. At this time, the apex of the pressing curved surface, the surgical wound, and the wound end of the inner simulated blood vessel are basically aligned in the length direction. Adjust the pressure dispersion tube to the bone part or decompression part on the back of the wound, tighten the bandage and fix it. S5. Rotate the knob of the pressing device to push the pressing surface to apply a preset pressure to the surgical wound. The pressing device and the inner simulated blood vessel are magnetically attracted and cooperated. The external magnetic force causes the magnetic film on the outer wall of the inner simulated blood vessel to open. The magnetic film cooperates with the external magnetic force to press the blood vessel wound wall tightly against it. Then, release the hemostatic device at the blood supply end of the blood vessel to restore blood supply. S6. Blood enters the blood inlet micropore at the rear end of the simulated blood vessel through the human blood vessel inside the second micropore wound, flows out from the front end through the hollow channel at the wound end of the simulated blood vessel, and re-enters the human blood vessel. Continue to press and recover for 2 hours or more. S7. If the patient experiences discomfort due to insufficient blood supply; The pressure of the temporary rotary compression device is released. The compression device generates a magnetic attraction and lifting effect on the internal simulated blood vessels, causing the compressed human blood vessels to be released first to achieve a short-term blood supply. At the same time, the magnetic force attracts the magnetic material on the curved surface of the internal simulated blood vessels and the compression device. The magnetic attraction force appropriately presses the wound skin layer, thereby further protecting the function of the wound coagulation layer. After a few seconds of blood supply, the compression pressure is restored. Alternatively, increase the number of internal or external simulated blood vessels at the arteries / veins at the anterior and posterior ends of the wound; S8. After the surgical wound has healed and coagulated, release the pressing device and pull out the simulated blood vessel. Manually press the second micro-hole wound for several minutes, or until the bleeding stops.

[0020] Furthermore, in step S4, if the grooved miniature vascular clamp is used instead of the pressing device, the groove of the grooved miniature vascular clamp is matched with the inner simulated blood vessel to clamp the vascular wound. The clamping force is adjusted according to the wound condition so that the grooved miniature vascular clamp clamps part of the blood vessel, leaving a gap for natural blood flow, without the need for additional bandages and external pressure devices; or the blood vessel is completely clamped, and blood is supplied only through the inner simulated blood vessel.

[0021] The advantages of this invention compared to existing technologies are as follows: This invention simulates blood vessels to construct blood flow channels under pressure, and combines the synergistic effect of magnetic and mechanical forces to increase blood flow during the pressure phase to more than 20%-60%, creating a second micro-pore wound to reduce the difficulty of healing. At the same time, the back-end system realizes pathological analysis and personalized treatment plan push, which is suitable for cardiovascular interventional surgery and rehabilitation treatment of various vascular wounds. It has significant advantages of minimal trauma, fast recovery, less pain, and high safety. Attached Figure Description

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0026] Example 1 like Figure 1-6 As shown in Figures 8 and 9, this embodiment provides a wound treatment device with magnetic simulated blood vessels, including a simulated blood vessel component 1, a pressing device 2, and a background intelligent analysis system 3.

[0027] The simulated blood vessel component 1 includes an inner simulated blood vessel 11 and an outer simulated blood vessel 12. The simulated blood vessel component 1 is used to create a second micro-hole wound. The diameter of the second micro-hole wound is 1 / 3 of the surgical wound or the outer diameter of the inner simulated blood vessel, resulting in minimal trauma and easy healing.

[0028] The internal simulated blood vessel 11 has a hollow channel structure with an outer diameter of 0.8 mm. It is divided into a front end 111, a wound end 112, a rear end 113, a new wound end 114, and a handle end 115 along the axial direction. The front end 111 is designed as a needle tip outlet for easy insertion into the radial artery. The rear end 113 has blood inlet micropores 1131 on its wall. The blood inlet micropores 1131 have a combination of circular and elongated structures. There are 12 elongated blood inlet micropores 1131.1 and 20 circular micropores 1131.2. The pore diameter is adjusted to 0.1 mm according to the blood inlet volume requirements of adult patients. The handle end 115 is equipped with a medical positive pressure connector at its tail, which can be connected to an infusion device for delivering hemostatic drugs. The outer wall of the internal simulated blood vessel 11 has a magnetic coating. The magnetic coating is made of nanoscale magnetic material, which has good biocompatibility and can generate a stable magnetic attraction with the pressing device 2.

[0029] The external simulated blood vessel 12 is a tubular structure consisting of a bidirectional needle and an intermediate infusion tubing. One vessel is provided and used in conjunction with the internal simulated blood vessel 11 to assist in blood flow and drug delivery.

[0030] The pressing device 2 consists of a knob 21, a spring 22, a support plate 23, and a pressing curved surface 24, arranged from top to bottom. Below the pressing curved surface 24 is a magnetic material 241 (using medical-grade neodymium iron boron permanent magnets, providing gentle and stable magnetic force). Below the magnetic material 241 is a pressing soft rubber layer 243 (made of medical-grade silicone). A curved groove 242, 5mm deep, is located in the middle, which cooperates with the internal simulated blood vessel 11 for pressing and positioning. The pressing device 2 also includes a bandage 25, which is a double bandage with Velcro fastening at the ends. Two pressure-dispersing hoses 251 are installed on the bandage, and a sliding rail structure connects the pressure-dispersing hoses 251 to the bandage 25, allowing for free sliding and natural fixation. The left side of the support plate 23 is the movable end of the bandage, and the right side is the fixed end, facilitating adjustment of the bandage tightness.

[0031] The background intelligent analysis system 3 includes a large language model analysis module 31 and a pathological reverse analysis module 32. The large language model analysis module 31 establishes big data related to cardiovascular diseases, covering information on race, age, gender, occupation, blood lipids, blood pressure, and cardiovascular-related indicators. The pathological reverse analysis module 32 generates a personalized treatment plan based on the patient's specific data (such as age 55, male, hypertension, radial artery intervention surgery, and incision diameter of 3mm), determines the compression pressure to be 0.3MPa, and the continuous compression rehabilitation time to be 3 hours.

[0032] This embodiment also provides a wound treatment method using a wound treatment device equipped with a magnetic simulated blood vessel, comprising the following steps: S1. After the radial artery interventional procedure is completed, pressure hemostasis is applied to the blood supply end of the radial artery, and the surgical wound is cleaned with medical sterile gauze to ensure that the wound is clean and free of foreign objects.

[0033] S2. At the radial artery site 2cm behind the surgical wound 5, a second micro-hole wound (1mm in diameter) is created by directly inserting an internal simulated blood vessel 11 with a needle-tip exit at the front end 111. A closed sterile adhesive tape is then applied to the outer skin of the second micro-hole wound 4 to prevent infection.

[0034] S3. Insert the internal simulated blood vessel 11 into the human radial artery through the second micro-hole wound 4, so that the wound end 112 of the internal simulated blood vessel 11 is basically aligned with the surgical wound 5, and the new wound end 114 is adapted to the position of the second micro-hole wound 4, so as to ensure that the blood inlet micro-hole 1131 can effectively collect blood.

[0035] S4. Place the pressing device 2 on the surgical wound 5, so that the curved groove 242 of the pressing surface 24 fits and is positioned with the inner simulated blood vessel 11. At this time, the apex of the pressing surface 24, the surgical wound 5, and the wound end 112 of the inner simulated blood vessel 11 are aligned in the length direction. Adjust the pressure dispersion hose 251 to the radial part on the back of the wound, tighten the bandage 25 and fix it with Velcro, adjust the tightness of the bandage to ensure that the pressing device 2 is firmly fixed and the patient has no obvious discomfort.

[0036] S5. Rotate the knob 21 of the pressing device 2 to push the pressing surface 24 to apply a preset pressure of 0.3MPa to the surgical wound 5. The magnetic material 241 of the pressing device 2 and the magnetic coating 117 of the inner simulated blood vessel 11 will generate a magnetic attraction. The external magnetic force will cause the magnetic coating 117 on the outer wall of the inner simulated blood vessel 11 to move the inner wall of the blood vessel to adhere, pressing the blood vessel wound wall tightly to achieve hemostasis. Then release the hemostasis device at the radial artery supply end to restore blood supply.

[0037] S6. Blood enters the radial artery inside the second micro-perforation wound 4, enters the blood inlet micro-hole 1131 at the rear end 113 of the inner simulated blood vessel 11, flows through the hollow channel inside the wound end 112 of the inner simulated blood vessel 11, and then flows out from the front end 111, re-entering the human radial artery to form a complete blood flow circuit; continuous pressure is applied for rehabilitation for 3 hours, during which the patient's vital signs and wound condition are observed.

[0038] S7. If the patient experiences dizziness, numbness in the wrist, or other discomfort due to insufficient blood supply, temporarily loosen the knob 21 of the pressing device 2 to reduce the pressing pressure. The pressing device 2 will generate a magnetic attraction and lifting effect on the internal simulated blood vessel 11, causing the pressed radial artery to be released first to achieve a brief blood supply (lasting 5 seconds). At the same time, the magnetic force attracts the magnetic material 241 on the curved surface of the internal simulated blood vessel 11 and the pressing device 2. The magnetic attraction force will appropriately press the wound skin layer to protect the wound coagulation layer. After the blood supply is finished, tighten the knob 21 again to restore the pressing pressure to 0.3 MPa.

[0039] S8. After the surgical wound has healed (without bleeding or redness), untie the bandage 25 and the pressure device 2, gently pull out the internal simulated blood vessel 11, manually press the second micro-hole wound 4 for 5 minutes to ensure hemostasis, and then apply sterile adhesive tape to complete the treatment.

[0040] Example 2 like Figure 7-8 As shown, the difference between this embodiment and embodiment 1 is that: the pressing device 2 uses a grooved miniature vascular clamp 26 instead of a knob-type pressing structure, and does not include a bandage 25 and a pressure dispersion hose 251; the inner simulated blood vessel 11 is a non-circular simulated blood vessel, with a curved non-circular structure between the front end 111, the blood inlet micro-hole 116 and the new wound end 114, with a bending angle of 60° to fit the wound position on the inside of the wrist; the outer wall of the inner simulated blood vessel 11 is provided with a magnetic thin film (made of nano-scale thin film material and medical memory metal composite, with a thickness of 0.08mm); the diameter of the second micro-hole wound is 1 / 4 of the surgical wound.

[0041] The grooved miniature vascular clamp 26 includes a vascular clamp arm 261, a second spring 262, a central rotating shaft 263, and a vascular clamp holding end 264. A magnet is provided on the rear half of the vascular clamp holding end 264, and a soft rubber layer 265 is provided on the inner surfaces of both sides of the vascular clamp holding end 264. The surface of the soft rubber layer 265 is a shallow corrugated groove. The groove of the grooved miniature vascular clamp 26 cooperates with the inner simulated blood vessel 11 for clamping.

[0042] The difference between the wound treatment method in this embodiment and that in embodiment 1 is in step S4: the groove of the grooved miniature vascular clamp 26 is matched with the inner simulated blood vessel 11 to clamp the wound site of the blood vessel. The clamping force is adjusted according to the wound condition so that the grooved miniature vascular clamp 26 clamps part of the blood vessel, leaving a gap for natural blood flow, without the need for additional bandages and external pressure devices; in step S8, the grooved miniature vascular clamp 26 is directly released and the inner simulated blood vessel 11 is pulled out.

[0043] This embodiment is suitable for wounds such as those on the inside of the wrist that are difficult to fix with bandages, making the operation more convenient. At the same time, the irregular internal simulated blood vessels can better adapt to the direction of blood vessels, improving the blood flow effect and the accuracy of pressure positioning.

[0044] Furthermore, such as Figure 9As shown, during the insertion and compression phases of the internal simulated blood vessel 11, in order to prevent secondary trauma to the inner wall of the blood vessel caused by compression of the needle tip of the internal simulated blood vessel 11, the doctor can control the direction of the needle tip by adjusting the direction of the handle of the internal simulated blood vessel 11, so that the tip of the needle is pointing towards the source of the compression force. This can greatly prevent secondary trauma to the inner wall of the blood vessel caused by compression of the needle tip. At the same time, after adjusting the direction of the needle tip, the direction of the needle tip can be properly fixed by attaching a foam block 116 and external medical tape to the handle, so that the direction of the needle tip will not change due to the movement of the arm, and ultimately play a role in protecting the inner wall of the blood vessel.

[0045] The treatment sequence described in the above embodiments and claims can be adjusted according to the doctor's treatment habits or the needs of the injury, or some parts of the procedure can be added or removed depending on the injury.

[0046] The outer wall of the inner simulated blood vessel 11 is polished to make the surface smooth, and a nano-coating can also be applied to ensure smoothness; the magnetic material of the inner simulated blood vessel 11 can also be made directly from magnetic alloy materials.

[0047] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The magnetic attraction force appropriately presses the wound skin layer, thereby further protecting the function of the wound coagulation layer. After a few seconds of blood supply, the compression pressure is restored. Alternatively, increase the number of internal or external simulated blood vessels at the arteries / veins at the anterior and posterior ends of the wound; S8. After the surgical wound has healed and coagulated, release the pressing device and pull out the simulated blood vessel. Manually press the second micro-hole wound for several minutes, or until the bleeding stops.

10. The wound treatment method according to claim 9, which uses a wound treatment device with magnetic simulated blood vessels, is characterized in that... In step S4, if the grooved miniature vascular clamp is used instead of the pressing device, the groove of the grooved miniature vascular clamp is matched with the inner simulated blood vessel to clamp the wound site of the blood vessel. The clamping force is adjusted according to the wound condition so that the grooved miniature vascular clamp clamps part of the blood vessel, leaving a gap for natural blood flow, without the need for additional bandages and external pressure devices; or the blood vessel is completely clamped, and blood is supplied only through the inner simulated blood vessel.
