Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a femoral artery compression device with timed rebound. Background Art

[0002] DSA is short for Digital Subtraction Angiography, which is a technology used in the field of medical imaging. DSA technology uses X-rays and computer processing to produce high-contrast images of blood vessels, thereby helping doctors diagnose and treat various vascular diseases.

[0003] When performing DSA examination or interventional treatment, it is usually necessary to insert a catheter through the femoral artery. This process will leave a small puncture point on the femoral artery. When the examination or operation is over, if the catheter is removed without proper compression, it may cause bleeding at the puncture point. Since the femoral artery is a large blood vessel, the amount of bleeding may be large, and even life-threatening in severe cases. Therefore, the puncture point needs to be compressed after the operation. The existing treatment method is usually that medical staff directly apply pressure to the puncture point with their hands or use gauze pads and bandages, but it requires long-term manpower investment and it is difficult to ensure continuous and uniform pressure, which may cause discomfort to the patient.

[0030] The embodiment of the present application provides a timed-rebound femoral artery compression device, which is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0031] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0032] Example 1

[0033] See also Figure 1-8 In this embodiment, a timed-rebound femoral artery compression device is provided, which is characterized by comprising: a shell 1, a storage box 2 is provided inside the shell 1, a first airbag 202 is provided inside the storage box 2, a ring block 204 is connected to the bottom of the shell 1, and a second airbag 205 is provided inside the ring block 204; a fixing component arranged on the outside of the shell 1, used to fix the shell 1 on the patient, the fixing component includes: a first strap 8 and a second strap 9; and an adjusting component arranged inside the shell 1, used to adjust the pressure of the second airbag 205, the adjusting component includes: a threaded rod 102, a fixing block 3, a stepping motor 301, a rotating rod 302, a pressure plate 4 and a moving block 403.

[0034] By cooperating with the first airbag 202, the second airbag 205, the fixing component and the adjusting component, the shell 1 can be fixed to the patient, and a uniform pressure force can be applied to the femoral artery puncture point of the patient, thereby solving the problems of long time and uneven pressure required for manual compression. The first strap 8 and the second strap 9 are wrapped around the patient's waist and thighs to cover the patient's exposed lower body and protect the patient's privacy to the greatest extent. At the same time, during the compression process, the connection structure with the pressure plate 4 is switched so that the pressure plate 4 is moved up regularly during the compression process to reduce the pressure on the femoral artery and avoid tissue damage caused by long-term compression.

[0035] Example 2

[0036] On the basis of Example 1, the shell 1 is rotatably connected to a threaded rod 102, the top of the threaded rod 102 protrudes from the outer surface of the shell 1 and is connected to a knob 101, the threaded rod 102 is externally threadedly connected to a pressure plate 4, a stepper motor 301 is installed inside the shell 1, the top of the stepper motor 301 is driven and connected to a rotating rod 302, a moving groove 402 is opened inside the pressure plate 4, and the moving groove 402 is communicated with the adjusting hole 401, a moving block 403 is slidably connected inside the moving groove 402, both ends of the moving block 403 are connected to arc blocks 405, and the inner arc surface of the arc block 405 is provided with threads, and the two arc blocks 405 are respectively threadedly connected to the threaded rod 102 and the rotating rod 302; a lifting groove 201 is opened on one side of the storage box 2, the pressure plate 4 extends into the storage box 2 through the lifting groove 201, and a connecting pipe is provided between the first airbag 202 and the second airbag 205.

[0037] When compressing the patient's femoral artery, the shell 1 can be fixed on the patient and the second airbag 205 can cover the compression position. Then, the knob 101 is rotated to drive the threaded rod 102 to rotate. At this time, the threaded rod 102 is threadedly engaged with the arc block 405, so that the arc block 405 drives the pressure plate 4 to move under the action of the threaded engagement, and then the pressure plate 4 moves downward to squeeze the first airbag 202, so that the gas inside the first airbag 202 enters the second airbag 205 through the connecting tube 203, so that the second airbag 205 expands and compresses the femoral artery, and the amount of gas entering the second airbag 205 is adjusted by controlling the moving distance of the pressure plate 4, thereby changing the internal air pressure of the second airbag 205 to meet the actual needs of the patient's femoral artery compression.

[0038] Example 3

[0039] On the basis of Example 1 and Example 2, a sensing plate 103 is installed inside the shell 1, a plurality of infrared sensors are provided on one side of the sensing plate 103, a buzzer 104 is installed on the other side of the sensing plate 103, two adjustment holes 401 are provided on the pressure plate 4, and the threaded rod 102 and the rotating rod 302 pass through the adjustment holes 401, an extrusion groove 404 is provided on the moving block 403, an extrusion block 5 is passed through the extrusion groove 404, and a mounting block 6 is installed inside the moving groove 402.

[0040] During the downward movement of the pressure plate 4, the extrusion block 5 at the bottom of the pressure plate 4 contacts the fixed block 3, and as the pressure plate 4 moves downward, the extrusion block 5 is resisted by the fixed block 3 and moves upward relative to the moving block 403 until the top of the extrusion block 5 contacts the inner wall of the moving groove 402, so that the inclined surface on the extrusion block 5 contacts the extrusion groove 404, and drives the moving block 403 to move in the moving groove 402. At this time, the arc block 405 at one end of the moving block 403 is received in the moving groove 402 and separated from the threaded rod 102, releasing the control of the knob 101 and the threaded rod 102 on the pressure plate 4, and at the same time, the arc block 405 at the other end of the moving block 403 moves out of the moving groove 402 and engages with the rotating rod 302.

[0041] A control switch is provided on the top of the fixed block 3 for controlling the start of the stepper motor 301, and a matching microcontroller is provided on the stepper motor 301, which can be programmed to set the specific movement mode, speed and movement time of the stepper motor 301. After the built-in timing ends, the stepper motor 301 can be controlled to rotate the rotating rod 302 one circle to drive the pressure plate 4 to move up a certain distance;

[0042] The model of the stepper motor 301 is 28BYJ-48, and the model of the microcontroller is Arduino Uno R3. The stepper motor 301 and the microcontroller are mature conventional technologies in this technical field, and this solution does not make any improvements to the circuit or program of the stepper motor 301 and the microcontroller model. Therefore, the circuit and signal connection relationship between the stepper motor 301 and the microcontroller model will not be described in detail.

[0043] When the bottom of the squeezing block 5 contacts the fixed block 3, the squeezing block 5 can start the stepper motor 301 through the control switch on the top of the fixed block 3, so that the stepper motor 301 drives the rotating rod 302 to rotate, and the rotating rod 302 is threadedly engaged with the moving block 403 through the arc block 405, so that the rotating rod 302 drives the pressure plate 4 to move upward during the rotation, reducing the pressure of the pressure plate 4 on the first airbag 202. At this time, the internal space of the first airbag 202 and the second airbag 205 increases, and the air pressure decreases, thereby reducing the pressure of the second airbag 205 on the eastern meridian, avoiding tissue damage caused by long-term compression;

[0044] Then, during the upward movement of the pressure plate 4, the infrared sensor of the sensing plate 103 can sense the pressure plate 4 when the pressure plate 4 moves to the top, and start the buzzer 104 to emit a sound, reminding the medical staff that the compression time has arrived;

[0045] Then, when the pressure plate 4 moves downward, the rotating rod 302 and the corresponding adjustment hole 401 serve as a limiting structure for the pressure plate 4. Then, when the pressure plate 4 moves upward, the threaded rod 102 and the corresponding adjustment hole 401 serve as a limiting structure for the pressure plate 4 to prevent the pressure plate 4 from positional displacement during movement.

[0046] Among them, a card slot 502 is opened on one side of the top of the extrusion block 5, and limiting slots 501 are opened on both sides of the bottom of the extrusion block 5. A slot 406 is opened at the bottom of the pressure plate 4, and the bottom of the extrusion block 5 extends into the slot 406. A limiting block 407 matching the limiting slot 501 is connected to the inner wall of the slot 406. A fixing block 3 is installed inside the shell 1, and the fixed block 3 corresponds to the position of the extrusion block 5. An ejection slot 601 is opened on one side of the mounting block 6, and the ejection slot 601 corresponds to the position of the card slot 502. An ejection spring 602 is connected inside the ejection slot 601, and one end of the ejection spring 602 is connected to the inner wall of the ejection spring 602. An ejection block 603 is connected, and one end of the ejection block 603 extends into the card slot 502 and is provided with an inclined surface. A pressing groove 604 is opened on the top of the ejection block 603, and a pressing hole 605 is opened on the top of the pressure plate 4, and the pressing hole 605 is communicated with the ejection groove 601. A pressing rod 606 is connected to the inner wall of the top of the shell 1, and the pressing rod 606 corresponds to the position of the pressing hole 605. A reset groove 702 communicated with the moving groove 402 is opened inside the pressure plate 4, and a reset plate 7 is fixedly connected to one side of the moving block 403, and a reset spring 701 is connected between the reset plate 7 and the reset groove 702.

[0047] Then, when the extrusion block 5 moves upward relatively, the extrusion block 5 contacts the inclined surface of the ejection block 603, and squeezes the ejection block 603 into the ejection groove 601. After the top of the extrusion block 5 contacts the inner wall of the moving groove 402, the slot 502 on the extrusion block 5 corresponds to the position of the ejection block 603, so that the ejection block 603 pops out under the elastic force of the ejection spring 602, and the ejection block 603 is inserted into the slot 502, completing the clamping and fixing of the position of the extrusion block 5, avoiding the extrusion block 5 from becoming loose in the process of the pressure plate 4 moving upward, resulting in the position deviation of the moving block 403 and the arc block 405, affecting the movement of the pressure plate 4, and the setting of the limit block 407 and the limit slot 501 can limit the moving direction and distance of the extrusion block 5;

[0048] When the pressure plate 4 moves to the highest point, the pressing rod 606 is just inserted into the pressing groove 604, and the bottom end of the pressing rod 606 contacts the pressing groove 604 on the ejection block 603, and brings the ejection block 603 into the ejection groove 601, so that the ejection block 603 is separated from the card slot 502, and the restriction on the extrusion block 5 is released. When the moving block 403 moves toward the rotating rod 302, the moving block 403 drives the reset plate 7 to squeeze the reset spring 701, so that the reset spring 701 accumulates elastic force. After the restriction of the extrusion block 5 is released, the moving block 403 rebounds under the action of the elastic force of the reset spring 701, so that the moving block 403 and the extrusion block 5 are reset. At this time, the arc block 405 on the moving block 403 is threadedly engaged with the threaded rod 102 again, and the mode switching is completed.

[0049] Example 4

[0050] On the basis of Example 1, the shell 1 is connected to two opposite sides with first straps 8, and a first Velcro 801 is provided on the surface of the first straps 8. The other two opposite sides of the shell 1 are connected to second straps 9, and a second Velcro 901 is provided on the second straps 9. The width of the first strap 8 is greater than that of the second strap 9.

[0051] When fixing the shell 1, the adjacent first strap 8 and second strap 9 can be wrapped around the patient's waist, and fixed at the back of the patient's waist through the setting of the first Velcro 801 and the second Velcro 901, and then the other first strap 8 and second strap 9 can be wrapped around the patient's thigh, and fixed through the first Velcro 801 and the second Velcro 901. At this time, the shell 1 is positioned at the position where the femoral artery of the patient's thigh needs to be compressed.

[0052] Example 5

[0053] On the basis of Example 1, Example 2 and Example 3, further, an air inlet pipe 105 and an air deflation pipe 106 are connected to one side of the shell 1, and the air inlet pipe 105 and the air deflation pipe 106 are in communication with the first airbag 202. Before or during use, if it is found that the compression force of the shell 1 on the compression part is insufficient, the air inlet pipe 105 can be connected to an external air pump or airbag for manual inflation to increase the total amount of gas inside the first airbag 202 and the second airbag 205, thereby increasing the compression force generated by the second airbag 205. If it is found that the compression force is too large during the compression process, the deflation can be manually adjusted through the setting of the air deflation pipe 106 to avoid damage to the compression position due to excessive compression force.
