Description

Technical Field

[0001] The invention belongs to the technical field of medical puncture assistance, and in particular is a cardiovascular puncture assistance functional device. Background Art

[0002] Cardiovascular puncture technology is an important diagnostic and treatment method widely used in the field of cardiovascular medicine. Puncture surgery is a diagnostic and treatment technique in which a puncture needle is inserted into the body cavity to extract secretions for testing, inject gas or contrast agent into the body cavity for angiography, or inject drugs into the body cavity. The purpose of this operation can be diagnostic or therapeutic. There are many types of puncture surgery depending on the puncture site and purpose. In cardiovascular medicine, puncture surgery is mainly used to diagnose and treat diseases related to the heart and vascular system.

[0003] Angiography is usually required for the diagnosis of some cardiovascular diseases. Angiography is an examination method that injects contrast agents into blood vessels and uses imaging techniques such as X-rays to display the internal structure and pathological conditions of blood vessels. Puncture is a crucial step in this process because it allows doctors to insert a special puncture needle or catheter directly into the target blood vessel. In this way, the contrast agent can be accurately injected into the blood vessel through the puncture needle or catheter, thereby achieving direct observation of the internal conditions of the blood vessel.

[0004] Although some existing cardiovascular puncture auxiliary function devices can play an important role in improving puncture accuracy, stability and patient comfort, it will be difficult to produce ideal results for some patients with unclear blood vessels. Therefore, it is necessary to propose a cardiovascular puncture auxiliary function device, which can improve puncture accuracy, stability and patient comfort while facilitating doctors to clearly observe the patient's blood vessel position, so as to improve puncture efficiency. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a cardiovascular puncture auxiliary function device. The present invention is simple and easy to operate. Through the coordinated work between the controller, binding component, guide component and moving component, it improves the puncture accuracy, stability and patient comfort while facilitating the doctor to clearly observe the patient's blood vessel position, thereby improving the puncture efficiency.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a cardiovascular puncture auxiliary function device, comprising a controller, a binding component, a guide component and a moving component, the binding component is mounted on the guide component, the moving component is slidably connected to the guide component, the moving component is fixedly connected to the driving component, the driving component is hinged to the puncture component, and the controller is electrically connected to the driving component;

[0007] The driving assembly includes a first support block fixedly connected to one side of the guide assembly, a second support block is symmetrically arranged at the bottom of the support block, a servo motor is fixedly connected inside the second support block, the output shaft of the servo motor is coaxially fixedly connected to a roller, and the output shaft of the servo motor is rotatably connected to the second support block at one end away from the servo motor, a moving groove is arranged at the bottom of the second support block, the roller is located in the moving groove, the moving groove is connected to a spray chamber and the bottom wall of the spray chamber is higher than the top wall of the moving groove, a drug injection port connected to the spray chamber is opened on the surface of the second support block, a spray pump is fixedly connected at the connection between the moving groove and the spray chamber, a one-way valve is fixedly connected at the connection between the drug injection port and the spray chamber, and the spray pump and the servo motor are electrically connected to the controller.

[0008] The principle of the basic solution is: the device is fixed to the patient's arm through the strap assembly, and then the servo motor is controlled by the controller to drive the roller to rotate, and at the same time the roller is in contact with the patient's skin, so that the friction between the roller and the patient's skin is used to push the moving assembly to slide along the guide assembly, thereby adjusting the position of the puncture assembly to be close to the area where puncture is required, so that subsequent doctors can perform puncture operations quickly and efficiently; at the same time, the disinfectant in the spray chamber is sprayed on the roller surface through the spray pump, so that it is evenly applied to the area where the patient needs puncture when the roller moves.

[0009] The beneficial effects of the basic solution are: 1. The controller precisely controls the movement of the servo motor to drive the roller to contact and slide with the patient's skin. This mechanism can automatically adjust the position of the puncture component to the optimal puncture point. This not only reduces the manual operation burden of medical staff, but also significantly improves the accuracy and efficiency of the puncture operation, reduces the error and time caused by manual position adjustment, and at the same time, after the puncture point is selected, the two rollers will move in the opposite direction at the same frequency to tighten the skin around the puncture point, so that the blood vessels are relatively fixed and their sliding properties are reduced, so that the puncture needle can enter the blood vessels more easily and accurately. At the same time, it can also make the blood vessels under the skin more prominent, so that the operator can clearly see the position and direction of the blood vessels, so as to select the best puncture point; and properly tightening the skin can reduce the damage of the needle to the surrounding tissues during the puncture process, because after the skin is tightened, the tissue layer that the needle needs to pass through becomes thinner, reducing the pain caused by friction and squeezing. The design of the spray pump can automatically spray disinfectant on the surface of the roller when the roller moves in the same direction, and evenly apply it to the puncture area during the rolling process of the roller, ensuring sufficient disinfection of the puncture site, effectively reducing the risk of infection during the operation, and ensuring the safety of the patient.

[0010] 2. The design of the binding component can secure the device to the patient's arm, thereby reducing the possibility that the present invention will fall off or loosen from the patient's arm when the patient's arm moves to a certain extent, causing the puncture component to move away from the area requiring puncture, or the puncture component to injure the patient, thereby improving the safety of blood vessel puncture.

[0011] 3. The design of the guide component and the moving component can move accordingly according to the movement state of the roller. When the roller moves in the same direction, the moving component slides in the corresponding direction along the guide component. When the roller stops moving or moves in the opposite direction at the same frequency, the position of the moving component is fixed, thereby facilitating the completion of subsequent vascular puncture surgery.

[0012] Furthermore, the binding assembly includes two support rods symmetrically arranged on the guide assembly, the bottom of the support rods are fixedly connected with a fixing plate, the two fixing plates are symmetrically arranged, and the bottom of the fixing plates are fixedly connected with a binding strap.

[0013] The beneficial effect of the basic solution is that the device can be fixed at the position where the patient needs to undergo vascular puncture through the fixing plate and the strap, ensuring that the device will not loosen or fall off during subsequent punctures, thereby improving safety.

[0014] Furthermore, the guide assembly includes a concave guide block fixedly connected to the top of the support rod, and a guide groove that slidably cooperates with the moving assembly is opened on one side of the groove of the concave guide block.

[0015] The beneficial effect of the basic scheme is: through the guide groove on the concave guide block that slides with the moving component, the moving component can slide along the guide groove under the push of the driving component, thereby adjusting the position of the puncture component to ensure that the doctor can perform the puncture operation quickly.

[0016] Furthermore, the movable component includes a clamping ring for fixing the ultrasonic probe, a first locking bolt for adjusting the locking degree of the clamping ring is threadedly connected to the clamping ring, a plurality of sliders slidingly matched with the guide groove are fixedly connected to the side of the clamping ring close to the guide groove, and the side of the clamping ring away from the guide groove is fixedly connected to the first support block.

[0017] The beneficial effect of the basic scheme is: through the sliding cooperation between the slider and the guide groove, when the two rollers move according to a preset rule, the slider slides accordingly along the guide groove, and then the clamping ring moves accordingly with the movement of the slider, thereby driving the movement of the puncture assembly to achieve horizontal movement of the puncture assembly; at the same time, by rotating the first locking bolt, the clamping degree of the clamping ring on the ultrasonic probe is adjusted to ensure the stability of the ultrasonic probe during the operation.

[0018] Furthermore, the puncture assembly includes a puncture needle and an angle plate hinged to the side of the first support block away from the clamping ring. The side of the angle plate away from the first support block is fixedly connected to a guide tube for guiding the puncture needle, and the surface of the guide tube is threadedly connected to a second locking bolt for fixing the puncture needle.

[0019] The beneficial effect of the basic scheme is: by rotating the angle plate along the hinge and moving the clamping ring, the angle and position of the puncture needle can be adjusted, thereby better performing blood vessel puncture, improving puncture efficiency and reducing the operating burden on doctors.

[0020] Furthermore, the middle part of the fixing plate is arc-shaped, and a number of air holes are opened on the arc-shaped surface of the fixing plate; the puncture needle is guided by the guide tube to perform puncture along the adjusted position and angle, thereby simplifying the puncture process and reducing the doctor's operating burden; at the same time, the puncture needle is fixed in the guide tube by the second locking bolt, thereby reducing the possibility of the puncture needle falling off before puncture and accidentally injuring the patient, thereby improving safety.

[0021] The beneficial effects of the basic scheme are: the middle part of the fixing plate is designed to be arc-shaped, which can make the fixing plate fit the patient's limbs more closely, thereby playing a better fixing role and reducing the possibility of loosening or falling off of the invention during puncture, thereby improving safety; at the same time, the design of the air vent can improve the ventilation efficiency of the contact surface between the patient and the fixing plate, thereby reducing the degree of sweating in the corresponding parts, improving the patient's comfort while further improving safety.

[0022] Furthermore, a boosting block is fixedly connected to the top of the puncture needle.

[0023] The beneficial effect of the basic solution is that the design of the booster block can increase the effective force points on the puncture needle, thereby making it easier for doctors to push the puncture needle to puncture the patient's blood vessels and improve puncture efficiency.

[0024] Furthermore, a plurality of rubber bumps are fixedly connected to the surface of the roller.

[0025] The beneficial effect of the basic solution is: through the design of the rubber bulge, the area where the patient needs to be punctured is massaged to promote blood flow, and at the same time it is beneficial to the bulge of the blood vessels in the area where the patient needs to be punctured, so as to facilitate subsequent doctor observation and puncture operations.

[0026] Furthermore, the drug injection port is arranged tilted, and one end of the drug injection port close to the surface of the second support block is higher than the other end of the drug injection port.

[0027] The beneficial effect of the basic scheme is that when the disinfectant is injected into the spray chamber, the injection port is tilted so that one end of the injection port is close to the surface of the second support block and is located above the other end, so that the disinfectant can flow quickly and completely into the spray chamber, thereby reducing the possibility of the disinfectant spilling during subsequent operations after the disinfectant is injected into the spray chamber.

[0028] Furthermore, the fixing plate and the concave guide block are both made of carbon fiber material.

[0029] The beneficial effects of the basic solution are: the fixing plate and the concave guide block are both designed with carbon fiber materials, and the characteristics of carbon fiber materials such as lightweight, high strength, and wear resistance are utilized to make the device have a certain elasticity and can be better stabilized on the surface of the patient's limbs. At the same time, it can also reduce the squeezing of the patient's limbs by the weight of the device itself after the patient wears the device as much as possible, thereby reducing the possibility of patient injury due to excessive squeezing.

DETAILED DESCRIPTION

[0034] The following is further described in detail through specific implementation methods:

[0035] Embodiment 1:

[0036] Basically as attached Figure 1 , Figure 2 and Figure 3 As shown: a cardiovascular puncture auxiliary function device, including a controller, a binding component, a guide component and a moving component, the binding component is installed on the guide component, the moving component is slidably connected to the guide component, the moving component is fixedly connected to the driving component, the driving component is hinged to the puncture component, and the controller is electrically connected to the driving component;

[0037] The driving assembly includes a first support block 10 fixedly connected to one side of the guide assembly by screws, a second support block 8 is symmetrically integrally formed at the bottom of the support block, a servo motor 20 is fixedly connected to the inside of the second support block 8 by screws, the output shaft of the servo motor 20 is coaxially keyed with a roller 19, and the output shaft of the servo motor 20 is rotatably connected to the second support block 8 at one end away from the servo motor 20, a moving groove is opened at the bottom of the second support block 8, the roller 19 is located in the moving groove, the moving groove is connected to a spray chamber 17, and the bottom wall of the spray chamber 17 is higher than the top wall of the moving groove, a drug injection port 15 connected to the spray chamber 17 is opened on the surface of the second support block 8, a spray pump 18 is fixedly connected to the connection point between the moving groove and the spray chamber 17 by screws, a one-way valve 16 is fixedly connected to the connection point between the drug injection port 15 and the spray chamber 17 by screws, and the spray pump 18 and the servo motor 20 are electrically connected to the controller.

[0038] The binding assembly includes two support rods 9 symmetrically fixedly connected to the guide assembly by screws, and the bottom of each support rod 9 is integrally formed with a fixing plate 1; the two fixing plates 1 are symmetrically arranged, and the bottom of each fixing plate 1 is bonded with a binding band 2. The guide assembly includes a concave guide block 4 fixedly connected to the top of the support rod 9 by screws, and one side of the groove of the concave guide block 4 is provided with a guide groove 5 for slidingly cooperating with the moving assembly.

[0039] The moving assembly includes a clamping ring 7 for fixing the ultrasonic probe, a first locking bolt 6 for adjusting the locking degree of the clamping ring 7 is threadedly connected to the clamping ring 7, a plurality of sliders for slidingly cooperating with the guide groove 5 are integrally formed on the side of the clamping ring 7 close to the guide groove 5, and the side of the clamping ring 7 away from the guide groove 5 is screw-fixedly connected to the first support block 10. The puncture assembly includes a puncture needle and an angle plate 12 hinged to the side of the first support block 10 away from the clamping ring 7, a guide tube 13 for guiding the puncture needle is integrally formed on the side of the angle plate 12 away from the first support block 10, and a second locking bolt 14 for fixing the puncture needle is threadedly connected to the surface of the guide tube 13.

[0040] The specific implementation process is as follows: first, the disinfectant is injected into the injection port 15, and then the disinfectant flows to the one-way valve 16, and then flows into the spray chamber 17 after passing through the one-way valve 16; after the injection of the disinfectant is completed, the one-way valve 16 will limit the disinfectant in the spray chamber 17 from flowing out of the spray chamber 17 through the injection port 15, thereby reducing the possibility of waste of the disinfectant in the spray chamber 17, and at the same time, the one-way valve 16 will also block the long-term direct contact between the disinfectant in the spray chamber 17 and the external air, thereby reducing the volatilization speed of the disinfectant, so as to further reduce the waste of the disinfectant.

[0041] Then, the clamping ring 7 is put on the ultrasonic probe, and then the locking bolt is turned to shrink the clamping ring 7 to clamp the ultrasonic probe, ensuring that the ultrasonic probe will not loosen or fall off when it moves with the clamping ring 7, thereby ensuring the stability of the ultrasonic feedback image, and making it easier for the doctor to clearly observe the specific situation on the patient's arm, so as to improve the puncture efficiency and safety.

[0042] Then, the two fixing plates 1 are placed on the patient's arm, and it is ensured that the concave guide block 4 is located directly above the puncture point to ensure the smooth progress of the subsequent puncture process. The device is fixed on the patient's arm through the strap 2 on the fixing plate 1; then the controller controls the two servo motors 20 to move in the same state, so that the output shaft of the servo motor 20 drives the roller 19 coaxially connected thereto to rotate in the same direction. Since the roller 19 is in contact with the patient's skin, the roller 19 will slide relative to the patient's skin when it rotates, thereby generating sliding friction. The upper slider is slidably matched with the guide groove 5, and the clamping ring 7 is fixedly connected to the first support block 10, and the first support block 10 is fixedly connected to the second support block 8, so the above-mentioned sliding friction force will cause the slider to slide along the guide groove 5, thereby driving the clamping ring 7 to slide relatively; at the same time, the angle plate 12 is hinged on the first support block 10, and the guide tube 13 is also fixed on the angle plate 12, so the guide tube 13 is indirectly controlled by the controller to align with the puncture point, which makes it convenient for subsequent doctors to quickly and efficiently perform puncture from the puncture point, so as to improve the puncture efficiency and safety.

[0043] At the same time, when the roller 19 rotates in the same direction, the controller will start the spray pump 18 to spray the disinfectant in the spray chamber 17 on the surface of the roller 19. Since the roller 19 is in contact with the patient's skin, as the roller 19 rotates and slides, the disinfectant on the surface of the roller 19 will be evenly applied to the area where puncture is required, so as to achieve the purpose of disinfection and sterilization, reduce the risk of infection, and improve the safety of puncture. After the puncture needle is inserted into the patient's blood vessel, the position of the puncture needle is fixed by rotating the second locking bolt 14, thereby reducing the burden on the doctor and facilitating his subsequent operations, and also reducing the possibility of puncture failure caused by misoperation.

[0044] And when the doctor needs to perform puncture, the two rollers 19 will rotate in opposite directions. Due to the friction between the rollers 19 and the patient's skin, the skin at the location where puncture is required is tightened, so that the blood vessels are relatively fixed to reduce their sliding properties, thereby making it easier and more accurate for the puncture needle to enter the blood vessels; at the same time, the blood vessels under the skin can be made more prominent, making it easier for the doctor to clearly see the location and direction of the blood vessels and thus select the best puncture point; and properly tightening the skin can make the tissue layer that the needle needs to pass through thinner to reduce the discomfort caused by friction and squeezing, and at the same time reduce the damage to the surrounding tissues by the needle during puncture.

[0045] Embodiment 2:

[0046] The difference from the above embodiment is that, as shown in the attached Figure 1 As shown: the middle part of the fixing plate 1 is arc-shaped, and a plurality of air holes 3 are opened on the arc-shaped surface of the fixing plate 1.

[0047] The specific implementation process is as follows: Since the shape of a human arm is usually similar to that of a cylinder, the middle part of the fixing plate 1 is set to an arc shape to conform to ergonomics, so that when the fixing plate 1 and the strap 2 are fixed together, the fixing plate 1 can fit the surface of the patient's arm more closely, thereby further improving stability; while increasing the fitting surface between the fixing plate 1 and the patient's arm, the air flow speed on the fitting surface on the patient's arm will also be reduced, thereby affecting the heat dissipation of the fitting surface, so a number of air holes 3 are opened on the arc surface of the fixing plate 1 to ensure that the air flows on the contact surface between the fixing plate 1 and the arm after the device is stabilized, so as to ensure its heat dissipation, thereby reducing the patient's discomfort.

[0048] Embodiment 3:

[0049] The difference from the above embodiment is that, as shown in the attached Figure 1 As shown: a boosting block 11 is clamped on the top of the puncture needle.

[0050] The specific implementation process is as follows: when the doctor pushes the puncture needle to puncture the patient's arm, the puncture needle is generally of slender specifications, which is not convenient for the doctor to hold and operate, increasing the difficulty of puncture. Therefore, the booster block 11 on the top of the puncture needle increases the effective pushing force point on the puncture needle, so that the doctor can more easily push the puncture needle to puncture the patient's arm, thereby improving the puncture efficiency and safety.

[0051] Embodiment 4:

[0052] The difference from the above embodiment is that, as shown in the attached Figure 3 As shown: a plurality of rubber bumps 21 are bonded to the surface of the roller 19 .

[0053] The specific implementation process is as follows: during the rotation of the roller 19, the rubber protrusion 21 on the surface of the roller 19 can increase the friction between the roller 19 and the skin of the patient's arm, preventing the roller 19 from slipping on the patient's skin, thereby improving the accuracy of the movement of the second support block 8, and then improving the position accuracy of the puncture needle, so that the doctor can perform blood vessel puncture quickly and efficiently later.

[0054] Embodiment 5:

[0055] The difference from the above embodiment is that, as shown in the attached Figure 2 As shown: the injection port 15 is tilted, and one end of the injection port 15 close to the surface of the second support block 8 is higher than the other end of the injection port 15.

[0056] The specific implementation process is as follows: when the disinfectant is injected into the spray chamber 17 through the injection port 15, since the injection port 15 is inclined and one end of the injection port 15 close to the surface of the second support block 8 is higher than the other end of the injection port 15, the disinfectant will all flow into the spray chamber 17 under the influence of its own gravity, thereby reducing the possibility of overflow of the disinfectant during injection and saving resources; at the same time, it can further prevent the disinfectant in the spray chamber 17 from shaking and flowing out from the injection port 15 when the second support block 8 moves subsequently.

[0057] Embodiment 6:

[0058] The difference from the above embodiment is that, as shown in the attached Figure 1 As shown: the fixing plate 1 and the concave guide block 4 are both made of carbon fiber material.

[0059] The specific implementation process is as follows: when the device is fixed on the patient's arm, the arm sizes of different patients are different to a certain extent, so the fixing plate 1 is made of carbon fiber material, not only to enable the fixing plate 1 to undergo corresponding deformation according to the size of the patient's arm when being stabilized, so as to better fit the patient's arm and reduce the possibility of the device falling off and loosening, but also to ensure the strength of the device while reducing the weight of the device as much as possible to reduce the burden on the patient's arm.

[0060] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
