Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a vascular compression device for post-operative femoral artery puncture intervention. Background Art

[0002] In the medical field, transfemoral artery puncture intervention is a widely used minimally invasive surgical method, often used in the diagnosis and treatment of various diseases such as cardiovascular disease, cerebrovascular disease, and peripheral vascular disease. This type of surgery involves puncturing the femoral artery and inserting catheters, guidewires and other instruments into the blood vessels to directly reach the site of the lesion for operation. After the operation, hemostasis and compression at the puncture point are key links in nursing, which are directly related to the patient's recovery effect and the incidence of postoperative complications.

[0003] However, traditional postoperative compression hemostasis methods for transfemoral artery puncture have many shortcomings. Traditional compression devices often lack precise compression force measurement and control functions, which can easily lead to insufficient compression force, ineffective hemostasis, or excessive compression force, causing tissue damage. Inaccurate compression force control not only increases the risk of postoperative bleeding, but may also lead to complications such as local tissue necrosis and hematoma formation. When adjusting the compression position and compression force, traditional devices usually require manual operation. Medical staff must rely on experience and repeated adjustments to achieve the appropriate compression effect. This not only increases the complexity of the operation, but also prolongs the surgical preparation time and postoperative care time, reducing work efficiency. In addition, the fixing structure of traditional compression devices is usually relatively fixed, making it difficult to quickly adapt to the needs of different patients. When facing different body shapes, different puncture positions, and different surgical scenarios, traditional devices often require additional auxiliary tools or complex adjustment processes to barely meet the usage requirements. Moreover, the fixing structure of traditional compression devices may not be strong enough and is easily displaced or loosened during use, affecting the compression effect. This not only reduces the reliability of compression, but also may require medical staff to frequently adjust the device, increasing the difficulty of care. To this end, a postoperative vascular compression device for transfemoral artery puncture intervention is proposed. Summary of the Invention

[0030] Some technical problems, main solutions, minor technical problems and solutions

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, an embodiment of the present invention provides a vascular compression device after femoral artery puncture intervention, comprising a fixing assembly 4 and a telescopic assembly 3 mounted on the fixing assembly 4, and further comprising:

[0033] The control display part 12 is mounted on the telescopic component 3;

[0034] The pressure head 6 is mounted on the telescopic assembly 3;

[0035] in:

[0036] The fixing assembly 4 includes a clamping disc 404, a fixing frame 401, a tightening handle 403 and an adjusting bolt 402, wherein the adjusting bolt 402 is moved by rotating the tightening handle 403, thereby pushing the clamping disc 404 and the clamped object toward the fixing frame 401, thereby firmly fixing the clamped object.

[0037] Specifically, the telescopic assembly 3 includes a first telescopic rod 301 , a second telescopic rod 302 and a third telescopic rod 303 . The third telescopic rod 303 is used to adjust the height of the device in the vertical direction.

[0038] Specifically, the second telescopic rod 302 is used to achieve horizontal length adjustment, the first telescopic rod 301 is used to achieve precise vertical movement of the pressure head 6, a first mounting bracket 10 is provided between the first telescopic rod 301 and the second telescopic rod 302, a fastening bolt 9 is provided between the second telescopic rod 302 and the third telescopic rod 303, a drive seat 1 is provided on one side of the first telescopic rod 301, and a stepper motor 2 is provided on the side of the drive seat 1 away from the first telescopic rod 301.

[0039] Specifically, a force sensor 7 is installed inside the pressure head 6 to measure the pressing force. The control display part 12 is used to collect the signal of the force sensor 7 and control the stepper motor 2 to apply pressure to the object being measured, thereby realizing closed-loop control and real-time parameter display and setting.

[0040] Specifically, the clamping plate 404 is fixedly connected to the adjusting bolt 402 , and driven by the adjusting bolt 402 , the clamping plate 404 moves in a direction perpendicular to the vertical side of the fixing frame 401 .

[0041] Specifically, an adjustment hand wheel 5 is provided on the outer side of the third telescopic rod 303 , and the positioning and movement of the inner telescopic rod can be achieved by adjusting the adjustment hand wheel 5 to loosen and lock it.

[0042] Specifically, the second telescopic rod 302 adopts a telescopic sleeve structure, and horizontal length adjustment is achieved through telescopic adjustment.

[0043] Specifically, a transmission mechanism is connected between the stepper motor 2 and the first telescopic rod 301. The stepper motor 2 drives the first telescopic rod 301 to move through the transmission mechanism, and then drives the pressure head 6 to move. A second mounting bracket 11 is arranged between the telescopic assembly 3 and the control display part 12. A rubber protective cover 8 is provided on the surface of the pressure head 6. The rubber protective cover 8 is used to contact the skin to improve comfort during the compression process.

[0044] Specifically, the control and display part 12 includes a signal acquisition module, a control module and a display module. The signal acquisition module is used to collect the signal of the force sensor 7. The control module controls the operation of the stepper motor 2 according to the signal collected by the signal acquisition module. The display module is used to display the pressure parameters and related setting parameters in real time.

[0045] In this embodiment, when the specific present invention is working: first, the device needs to be firmly installed in a suitable position, and the initial length of the telescopic rod needs to be finely adjusted to ensure that the pressure head 6 can accurately fit the compressed part. When the pressure head 6 contacts the compressed part, the force sensor 6 immediately senses the magnitude of the compression force and converts it into an electrical signal and transmits it to the control circuit. After receiving the electrical signal from the force sensor 6, the control circuit will quickly compare and analyze it with the preset compression force target value. If the actual compression force is detected to be lower than the preset standard, the control circuit will determine that the compression force is insufficient, and then generate a drive instruction to command the stepper motor 2 to rotate in the direction of increasing the compression force. On the contrary, if the actual compression force is higher than the preset value, the control circuit will determine that the compression force is too strong, and generate a drive instruction in the opposite direction, prompting the stepper motor 2 to rotate in the direction of reducing the compression force. If the actual compression force is just within the preset range, the control circuit will determine that the compression force is appropriate, maintain the current state of the stepper motor 2, and no adjustment will be made.

[0046] The driving instructions generated by the control circuit are accurately transmitted to the stepper motor 2, and the stepper motor 2 performs accurate rotation operations according to the direction and strength of the instructions. Specifically, the stepper motor 2 adjusts the pressure by driving the extension and contraction of the telescopic rod. When the stepper motor 2 rotates forward, the telescopic rod contracts and the pressure increases accordingly. When the stepper motor 2 rotates reversely, the telescopic rod extends and the pressure decreases accordingly. The stepper motor 2 has high-precision control capabilities and can achieve extremely fine angular rotation, thereby driving the telescopic rod to perform fine extension and contraction movements, thereby achieving precise control of the pressure. During the entire operation process, the force sensor 6 continuously monitors the changes in the pressure and feeds back real-time data to the control circuit. Based on these real-time feedback signals, the rotation direction and speed of the stepper motor 2 are dynamically adjusted to ensure that the compression force is always in real-time dynamic adjustment, which can ensure that the compression force is always maintained within the preset safety threshold. Even if the patient's position changes or encounters external interference, the compression force can be automatically and quickly adjusted to ensure the continuous stability and high reliability of the compression effect. Once the compression force exceeds the preset safety range (whether too high or too low), the control circuit will immediately trigger the alarm device and send out a striking sound and light alarm signal to promptly remind medical staff to intervene. In an emergency, medical staff can also manually operate the emergency stop button to instantly terminate the operation of the stepper motor 2, effectively avoiding unnecessary harm to the patient.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications and substitutions within the technical scope disclosed in the present invention, and such modifications and substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
