Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a radial artery compression device with multi-point pressing. Background Art

[0002] The radial artery is one of the terminal branches of the brachial artery and is slightly smaller than the ulnar artery. It originates from the brachial artery, runs outward and downward, first passes between the brachioradialis and pronator teres, then lies between the radial flexor carpi and the brachioradialis, passes obliquely through the deep surface of the tendons of the abductor pollicis longus and extensor pollicis brevis to the back of the hand, enters the anatomical nasopharyngeal fossa, passes through the first metacarpal space into the deep part of the palm, and after the main thumb artery is separated, it anastomoses with the deep palmar branch of the ulnar artery to form the deep palmar arch. The radial artery is an important blood vessel in the human body, which participates in the blood circulation of the human body and ensures the normal operation of blood, especially maintaining the blood supply and operation of the upper limbs.

[0003] When a blood sample is collected from the radial artery for blood gas analysis or other related tests, a radial artery compression device is required to compress the blood collection point after blood collection to promote hemostasis and prevent hematoma formation. After cardiac intervention via the radial artery, a radial artery compression device is required to compress the puncture site to ensure hemostasis and reduce complications.

[0004] The existing multi-point compression radial artery compression devices are mostly used to compress the patient's puncture point through a fixed-size compression block when in use. However, because the arm thickness of different people is different, for children, the diameter of the child's arm may be smaller than the diameter of the compression block. In this case, if the compression block is used to press the child's arm, it will be difficult for the compression block to press the puncture point. Therefore, it is necessary to propose a multi-point compression radial artery compression device that can select different compression columns according to different people. Summary of the invention

[0005] To solve the above problems, the present invention provides a multi-point compression radial artery compression device, which drives the adjustment plate to move horizontally through a rolling cylinder and a moving column, so that different pressing blocks can be selected to press the patient's arm to stop bleeding according to the thickness of the patient's arm.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: a multi-point compression radial artery compression device, comprising a box body, a controller fixedly connected to one side of the box body, a restraint tube for placing the patient's arm fixedly connected to the top of the box body, an opening is opened on the top of the restraint tube, an adjustment plate is slidably matched with the top of the restraint tube, both sides of the adjustment plate are provided with limit components for limiting the sliding position of the adjustment plate, and the top of the adjustment plate is provided with an extrusion component for compressing the radial artery.

[0007] The adjusting plate is provided with a plurality of circular holes of different diameters, all of which are located on the same straight line and above the openings, and each circular hole is vertically slidably fitted with a pressing block, and each circular hole bottom is fixedly connected with an elastic layer.

[0008] A rolling cylinder is rotatably connected in the box body, an arc groove is opened on the surface of the rolling cylinder, a moving column is fixedly connected to the bottom of the adjustment plate, and one end of the moving column away from the adjustment plate penetrates the box body and slides in the arc groove.

[0009] A driving assembly for driving the rolling drum to rotate is arranged on the surface of the box body.

[0010] An inflatable assembly for further fixing the patient's arm is provided in the restraint tube.

[0011] The technical principles of the above scheme are as follows:

[0012] The driving assembly drives the rolling cylinder to rotate, and the arc groove on the surface of the rolling cylinder slides with the moving column at the bottom of the adjustment plate, thereby driving the adjustment plate to move horizontally on the top of the restraint cylinder. In this way, different pressing blocks can be adjusted to compress the patient's arm according to the thickness of the patient's arm. When it is necessary to compress the puncture point on the patient's arm, the circular hole and the pressing block on the adjustment plate are used for precise positioning, and then the squeezing assembly is used to apply appropriate pressure to the patient's arm through the pressing block. This pressure can block the blood flow in the area, thereby achieving the purpose of hemostasis. The restraint cylinder is designed to wrap the patient's arm in it, and the patient's arm is inflated and fixed through the inflation assembly. This can reduce the movement or shaking of the arm during the compression process, ensuring the stability and safety of the compression.

[0013] When the pressing block stops being used, the elastic cloth will bounce the pressing block back into the round hole, completing the resetting process.

[0014] The above scheme has the following beneficial effects:

[0015] 1. The present invention can make precise adjustments according to the specific thickness of the patient's arm by adjusting the circular holes of different diameters on the plate and the slidingly matched pressing blocks, thereby ensuring the accuracy and effectiveness of pressing with different pressing blocks.

[0016] 2. The present invention fixes the restraint tube to the top of the box body, and when the patient puts his arm into the restraint tube, it may provide support force for the patient's arm, thereby improving the stability of the patient when pressing the radial artery.

[0017] Furthermore, the extrusion assembly includes a U-shaped plate, both ends of which are fixedly connected to the side walls of the box body, a threaded groove is opened on the top of the U-shaped plate, the threaded groove is located above the circular hole, the thread in the threaded groove is matched with a knob, and a pressing column is fixedly connected to the bottom of the knob.

[0018] Beneficial effects: The thread groove and the thread of the knob ensure the stable movement of the pressing column in the vertical direction, avoiding deviation or shaking during the pressure application process. At the same time, the design of the U-shaped plate ensures that the pressing column is always located above the round hole, ensuring the accuracy of the compression position. By rotating the knob, the height of the pressing column can be accurately adjusted to achieve precise compression of the patient's arm. This fine-tuning function ensures the accuracy and stability of the pressure and reduces the adverse consequences caused by excessive or insufficient pressure.

[0019] Furthermore, the diameter of the pressing column is smaller than the diameter of the circular hole.

[0020] Beneficial effect: When the diameter of the pressing column is smaller than the diameter of the circular hole, the pressing column can easily pass through the circular hole with the smallest diameter to press the pressing block in the circular hole. Both adults and children can choose the appropriate pressing block for pressing according to the thickness of their arms, thereby improving the applicability and practicality of the compression device.

[0021] Furthermore, the limiting assembly includes a plurality of limiting plates, each of which is slidably matched with a side of an adjacent adjustment plate, and one end of the limiting plate away from the adjustment plate is fixedly connected to the U-shaped plate.

[0022] Beneficial effect: A stable supporting structure is formed by the sliding cooperation between the limit plate and the adjustment plate, and the fixed connection between the limit plate and the U-shaped plate. The adjustment plate can only slide in one direction inside the limit plate, which is beneficial to the accuracy of the movement of the adjustment plate.

[0023] Furthermore, the inflation assembly includes a plurality of air bags, and the air bags are all fixedly connected to the inner wall of the restraint tube.

[0024] Beneficial effects: After the airbag is inflated, it can fit tightly around the patient's arm to form a stable fixation effect. This fixation method can not only effectively prevent the arm from moving or shaking during the operation, but also ensure the accuracy and stability of the compression. And due to the softness and plasticity of the airbag, the airbag can adapt to arms of different sizes and shapes.

[0025] Furthermore, the driving assembly includes a double-headed motor, and the controller is used to control the start and stop of the double-headed motor. When the position of the adjustment plate is adjusted, the double-headed motor is started by the controller.

[0026] The double-headed motor is fixedly connected to the side wall of the box body, the output shaft of the double-headed motor close to one end of the box body passes through the box body and is coaxially fixedly connected to the rolling cylinder, and a blowing component is arranged on the side of the double-headed motor away from the box body.

[0027] Beneficial Effects: The dual-head motor has a strong driving force and torque, which can ensure the stable and efficient rotation of the roller. This efficient drive not only improves the operating efficiency of the roller, but also enables the adjustment plate to move more smoothly, thereby achieving precise compression of the patient's arm.

[0028] Furthermore, the blowing assembly includes a fan, the output shaft of the double-headed motor at one end away from the box is coaxially fixedly connected to the fan, the fan is connected to an air duct, and the end of the air duct away from the fan is connected to the airbag.

[0029] Beneficial effects: The output shaft of the double-headed motor at one end away from the housing is coaxially fixedly connected to the fan, ensuring direct transmission of driving force and reducing energy loss. This connection method allows the fan to rotate stably and efficiently as the motor rotates, thereby generating a stable airflow. Due to the coaxial connection between the motor and the fan, and the smooth design of the air duct, the airflow can be efficiently transmitted from the fan to the airbag. This efficient transmission helps to improve the working efficiency of the entire blowing assembly, allowing the airbag to expand quickly and fully.

[0030] Furthermore, a solenoid valve is fixedly connected to the connection point between the airbag and the air guide tube, and a controller is used to control the opening and closing of the solenoid valve. When the airbag is inflated, the solenoid valve is controlled to open by the controller.

[0031] Beneficial effect: The inflation and deflation process of the airbag can be precisely controlled by the solenoid valve. When the airbag needs to be inflated, the solenoid valve opens to allow gas to flow into the airbag; when the airbag needs to be deflated, the solenoid valve opens to guide the gas to flow out, achieving rapid response and accurate adjustment of the airbag.

[0032] Furthermore, a disinfection lamp for disinfecting the restraining tube is fixedly connected to one side of the adjustment plate, and the controller is used to control the start and shut down of the disinfection lamp. When the restraining tube is disinfected, the disinfection lamp is started by the controller to disinfect the restraining tube.

[0033] Beneficial effects: The disinfection lamp can immediately disinfect the restraint tube, effectively kill bacteria, viruses and other microorganisms, and reduce the risk of cross infection. When the restraint tube needs to be reused, it can ensure the hygiene and safety of the restraint tube before each use.

[0034] Furthermore, transparent observation windows are provided on the surfaces of the U-shaped plate and the adjustment plate.

[0035] Beneficial effects: The transparent observation window allows medical staff to directly observe the inside of the restraint tube and the compressed radial artery area, thereby monitoring the patient's condition in real time. This real-time nature helps medical staff to promptly identify problems and make corresponding adjustments to ensure the safety and effectiveness of the treatment process. Through the observation window, medical staff can more accurately determine the position of the compression column, which is conducive to improving the accuracy of compression.

[0036] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is further described in detail through specific implementation methods:

[0042] Embodiment 1:

[0043] As attached Figure 1-Figure 3 As shown: a multi-point pressing radial artery compression device, including a box body 1, one side of the box body 1 is fixedly connected to a controller by screws, the top of the box body 1 is fixedly connected to a restraining tube 2 for placing a patient's arm by bolts, the top of the restraining tube 2 is opened with an opening, the top of the restraining tube 2 is slidably matched with an adjustment plate 3, both sides of the adjustment plate 3 are provided with limit components for limiting the sliding position of the adjustment plate 3, and the top of the adjustment plate 3 is provided with an extrusion component for compressing the radial artery.

[0044] like Figure 2 As shown, the adjustment plate 3 is provided with a plurality of circular holes 11 of different diameters, the circular holes 11 are all located on the same straight line and are all located above the openings, a pressing block 14 is vertically slidably fitted in the circular holes 11, and an elastic layer is fixedly connected to the bottom of the circular holes 11 by screws, and in this embodiment, a spandex layer is preferably used as the elastic layer.

[0045] A rolling cylinder 12 is rotatably connected inside the box body 1, and an arc groove 13 is opened on the surface of the rolling cylinder 12. A moving column 8 is fixedly connected to the bottom of the adjustment plate 3 by bolts. The end of the moving column 8 away from the adjustment plate 3 passes through the box body 1 and slides in the arc groove 13.

[0046] A driving assembly for driving the rolling drum 12 to rotate is disposed on the surface of the box body 1 .

[0047] An inflatable assembly for further fixing the patient's arm is arranged inside the restraint tube 2.

[0048] like Figure 1 and Figure 3 As shown, the extrusion assembly includes a U-shaped plate 4, both ends of which are fixedly connected to the side wall of the box body 1 by bolts, a thread groove is opened on the top of the U-shaped plate 4, the thread groove is located above the circular hole 11, a knob 5 is matched with the thread in the thread groove, and a pressing column 6 is fixedly connected to the bottom of the knob 5 by bolts. The diameter of the pressing column 6 is smaller than the diameter of the circular hole 11.

[0049] like Figure 1 and Figure 3 As shown, the limiting assembly includes a plurality of limiting plates 7, each of which is slidably matched with a side of the adjacent adjustment plate 3, and the top of each limiting plate 7 is fixedly connected to the U-shaped plate 4 by bolts.

[0050] The inflation assembly includes a plurality of air bags 18, and the air bags 18 are fixedly connected to the inner wall of the restraint tube 2 by screws.

[0051] like Figure 2 As shown, the driving assembly includes a double-headed motor 9, and the controller is used to control the start and stop of the double-headed motor 9. When the position of the adjustment plate 3 is adjusted, the double-headed motor 9 is started by the controller.

[0052] The double-headed motor 9 is fixedly connected to the side wall of the box body 1 by bolts. The output shaft of the double-headed motor 9 at one end close to the box body 1 passes through the box body 1 and is coaxially fixedly connected to the rolling cylinder 12 by bolts. A blowing component is provided on the side of the double-headed motor 9 away from the box body 1.

[0053] like Figure 3 As shown, the blowing assembly includes a fan 10, the output shaft at the left end of the double-headed motor 9 is coaxially connected to the fan 10 by bolts, the fan 10 is connected to an air duct 15, and the top of the air duct 15 is connected to the air bag 18. The connection between the air bag 18 and the air duct 15 is connected to a solenoid valve 16 by screws, and the controller is used to control the opening and closing of the solenoid valve 16. When the air bag 18 is inflated, the solenoid valve 16 is controlled by the controller to open.

[0054] The specific implementation process is as follows: First, the medical staff needs to put the patient's arm into the restraint barrel, and select a pressing block 14 suitable for the thickness of the patient's arm according to the thickness of the patient's arm. In this embodiment, the patient's arm is thinner as an example. Figure 2 As shown, it is necessary to select the circular hole 11 with the smallest diameter to align with the patient's arm.

[0055] by Figure 2For example, after the patient's arm is placed in the restraint cylinder 2, the medical staff can start the double-headed motor 9 through the controller, and the rotation of the double-headed motor 9 drives the rolling cylinder 12 to rotate. At this time, the rolling cylinder 12 needs to rotate clockwise. When the rolling cylinder 12 rotates clockwise, the moving column 8 will slide in the arc groove 13 along the direction of the arc groove 13. When the moving column 8 slides, the moving column 8 will drive the adjustment plate 3 to slide. As the adjustment plate 3 slides, the circular hole 11 with the smallest diameter will be aligned with the opening at the top of the restraint cylinder 2.

[0056] As the double-headed motor 9 rotates, the fan 10 is driven to rotate. Figure 3 For example, when the fan 10 rotates, the fan 10 will blow the generated wind into the air duct 15. At this time, the controller can control the solenoid valve 16 to open, and the wind generated by the fan 10 can enter the airbag 18 through the solenoid valve 16 to inflate the airbag 18.

[0057] As the airbag 18 is inflated, the airbag 18 will gradually fit the patient's arm and restrain the patient's arm.

[0058] When the airbag 18 is inflated and the position of the plate 3 to be adjusted is adjusted, the staff can control the double-headed motor 9 to stop rotating through the controller, and then the controller controls the solenoid valve 16 to close, thereby reducing the occurrence of air leakage of the airbag 18.

[0059] by Figure 1 and Figure 3 For example, at this time, the medical staff can rotate the knob 5, and the knob 5 will continue to move downward through the threaded groove. The downward movement of the knob 5 will drive the pressing column 6 to move downward. When the pressing column 6 and the pressing block 14 are against each other, the pressing column 6 will push the pressing block 14 to move downward together. At this time, the pressing block 14 will press the puncture point of the patient's arm, thereby achieving the effect of compression and hemostasis.

[0060] By selecting circular holes 11 of different diameters to align with the patient's arm, the applicability and comfort of the patient during radial artery compression can be improved. When the patient's arm is too thin, if an overly large pressing block 14 is used to press the patient's arm, the compression and hemostasis effect of the patient will be affected.

[0061] When the patient has finished pressing to stop bleeding, the medical staff can reversely rotate the knob 5 to move the pressing column 6 upward. When the pressing column 6 moves upward, the pressing block 14 will be reset to the circular hole 11 under the elastic force of the elastic layer, and the solenoid valve 16 will be opened through the controller to allow the gas in the airbag 18 to be discharged smoothly. Finally, the patient can take out his arm, and the process of compressing the radial artery to stop bleeding is completed.

[0062] Embodiment 2:

[0063] like Figure 1 As shown, the difference from the above embodiment is that a disinfection lamp 17 for disinfecting the restraining tube 2 is fixedly connected to one side of the adjustment plate 3 by bolts, and the controller is used to control the start and stop of the disinfection lamp 17. When the restraining tube 2 is disinfected, the disinfection lamp 17 is started by the controller to disinfect the restraining tube 2.

[0064] The specific implementation process is as follows: when the patient needs to receive radial artery compression treatment and the hygiene and safety of the restraint tube 2 need to be ensured during the treatment, a disinfection operation can be performed.

[0065] When the restraint tube 2 needs to be disinfected, the medical staff first ensures that no patient is using the restraint tube 2. Then, the controller starts the disinfection lamp 17. The disinfection lamp 17 starts to emit light, thereby generating ultraviolet rays to disinfect the inside of the restraint tube 2.

[0066] The restraint tube 2 can be regularly disinfected by the disinfection lamp 17 to effectively kill bacteria, viruses and other microorganisms, thereby reducing the risk of cross infection. Regular disinfection of the restraint tube 2 can also reduce the erosion of bacteria, viruses and other microorganisms, thereby extending the service life of the restraint tube 2 and the entire radial artery compression device.

[0067] Embodiment 3:

[0068] The difference from the above embodiment is that transparent observation windows are provided on the surfaces of the U-shaped plate 4 and the adjustment plate 3 .

[0069] The specific implementation process is as follows: When the patient is undergoing radial artery compression treatment, the transparent observation window is designed to help medical staff monitor the patient's condition in real time and ensure the safety and effectiveness of the treatment process.

[0070] The transparent observation window allows medical staff to directly observe the situation inside the restraint tube 2, including the patient's arm status, the position and compression force of the pressing column 6, etc. This helps medical staff to monitor the patient's status in real time and ensure the safety and effectiveness of the treatment process.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
