Description

Technical Field

[0001] This invention belongs to the field of compression hemostat technology, specifically relating to an electronic self-locking radial artery compression hemostat. Background Technology

[0002] Interventional procedures via the radial artery approach are challenging due to the large puncture diameter, the use of anticoagulants during the procedure, and the difficulty in achieving hemostasis at the puncture site. Incorrect pressure, inaccurate pressure placement, and excessive pressure duration can lead to complications. Existing compression hemostasis devices typically involve elastic bandage circumduction, requiring highly experienced operators. However, this method has several drawbacks: the elastic bandage generates tangential force, resulting in low pressure at the puncture site, leading to bleeding, prolonged hemostasis, and a higher risk of thrombosis; tightening the bandage provides greater pressure but can obstruct venous return, potentially causing aneurysms and thrombosis; the procedure is cumbersome, prone to cotton ball displacement causing oozing and hematoma; and patients find it inconvenient to loosen the bandage with one hand. Furthermore, the cumbersome procedures for hemostasis and decompression place a heavy workload on medical staff; and the inability to promptly observe local bleeding and skin conditions can lead to hemostasis failure. Summary of the Invention

[0003] The purpose of this invention is to provide an electronic self-locking radial artery compression hemostat to solve the technical problems in the prior art, such as inaccurate pressure on the bleeding point, poor control of compression force, and improper control of compression time, which can lead to complications and reduce the workload of medical staff.

Detailed Implementation

[0022] 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. The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. 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.

[0023] This invention provides, for example Figure 1-3 The electronic self-locking radial artery compression hemostat shown includes a main body 100, a wristband 200, a power mechanism 300, a pressure plate 400, a control panel 500, buttons 600, and a display 700.

[0024] The wristband 200 connects both ends of the main body 100 to form a shape that wraps around the arm and thus fixes the main body 100; the power mechanism 300 is installed inside the main body 100, and the power mechanism 300 includes a screw 304; the pressure plate 400 is connected to the end of the screw 304, and the pressure plate 400 is equipped with a ring sensor 402 and a pressure pad 401. The pressure plate 400 exerts pressure on the hemostatic site under the pressure force generated by the power mechanism 300.

[0025] The control board 500 is installed inside the main body 100. The control board 500 is connected to the power mechanism 300 and the ring sensor 402. It is used to collect the signal of the ring sensor 402 and control the movement of the power mechanism 300 to adjust the pressure of the pressure plate 400.

[0026] Specifically, such as Figure 4 , Figure 5 The power mechanism 300 consists of a motor 301, a turbine 302, a worm gear 303, and a screw 304. The motor 301 is equipped with a turbine 302, which meshes with the worm gear 303. The worm gear 303 is rotatably connected to the screw 304.

[0027] Furthermore, the rotation of the motor 301 causes the screw 304 to extend and retract, driving the pressure plate 400 to generate pressure or retraction force; the meshing connection between the worm gear 302 and the worm wheel 303 has a special mechanical structure that can self-lock, so that when the pressure plate 400 is subjected to a reverse force, it can maintain the pressure position and force without changing.

[0028] On the other hand, the power mechanism is a worm gear structure with a self-locking function. During the long period of compression hemostasis, the motor does not need to do any work, and the compression force can still be maintained firmly and persistently.

[0029] like Figure 6 A ring sensor 402 is installed on the pressure plate 400 to detect the patient's pulse tremor and bleeding during compression hemostasis.

[0030] The electronic self-locking radial artery compression hemostat used in this embodiment is as follows:

[0031] First, install the compression pad 401 onto the pressure plate 400, then wrap the wristband 200 around the patient's wrist, pass one end of the wristband 200 through the groove of the main body 100, and use Velcro to initially fix it; observe the position of the sheath corresponding to the puncture point, move the center of the pressure plate 400 to the puncture point, readjust the wristband 200, and fix the radial artery hemostat.

[0032] Specifically, the main body 100 has buttons 600, a display 700, a power mechanism 300 and a control board 500 installed inside the main body 100, and a screw 304 extending out of the main body 100 to provide pressure power. A pressure plate 400 is installed inside the main body 100 and the wristband 200, and a pressure pad 401 is installed on the pressure plate 400. The pressure pad 401 is made of soft and skin-friendly material, making the pressure position comfortable and replaceable.

[0033] Furthermore, buttons 600 and a display 700 are mounted on the top of the main body 100. The display 700 is connected to the control panel 500 to display the pressure and pressing time of the pressure plate 400. Buttons 600 are connected to the control panel 500 to adjust the pressure and pressing time of the power mechanism 300, and the adjustment is displayed on the display 700.

[0034] Specifically, a buzzer 501 is installed on the control board 500 to issue an alarm, and a charging interface 502 is installed on the control board 500 to charge the battery 800.

[0035] By pressing button 600, the electronic self-locking radial artery compression hemostat is activated, and the power mechanism 300 begins to move. The screw 304 drives the pressure plate 400 to compress towards the arm. When the pressure plate 400, carrying the ring sensor 402, approaches the patient's arm, the ring sensor 402 feeds back the patient's pulse thrill to the control board 500. If the ring sensor 402 does not receive the patient's pulse thrill, it sends a signal to the control board 500, controlling the power mechanism 300 to generate a retraction force, moving the pressure plate 400 away from the arm. Conversely, if the ring sensor 402 receives the patient's pulse thrill, it sends a signal to the control board 500, controlling the power mechanism 300 to generate compression force. Appropriate compression force will not obstruct venous return and will not cause aneurysms, thrombosis, or other complications. The compression force and duration can be automatically controlled, facilitating operation for medical workers, ensuring patient safety, and it is reusable.

[0036] Based on clinical usage data, the control panel 500 intelligently adjusts the pressure. As the pressure time increases, the control panel 500 controls the power mechanism 300 to gradually reduce the pressure on the hemostasis point in order to achieve better hemostasis and avoid the occurrence of complications.

[0037] Further optimization allows patients to observe the compression time and force on the display 700, and to set the compression time and force on the display 700 via the button 600.

[0038] When bleeding occurs in the patient's arm, the ring sensor 402 detects the blood flow and transmits the bleeding signal to the control board 500. The control board 500 then controls the buzzer 501 to sound an alarm, which helps the patient or medical staff to make a judgment and take action regarding the bleeding point, making compression hemostasis safer and more reliable. The control board can collect the signals from the sensor, make a judgment, control the buzzer to sound an alarm, and control the movement of the power mechanism to make the pressure plate generate pressure. The display can show the compression time and pressure. The buttons can activate the electronic self-locking radial artery compression hemostat and adjust the pressure.

[0039] Further optimization allows patients or medical staff to adjust the pressure level using button 600 to prevent bleeding.

[0040] In some other embodiments, the aforementioned buttons and displays can be replaced by LED displays with touch control panels. The LED display with touch control panels may include a panel bracket, a housing, a display screen body, a capacitive touch switch panel, and a glass cover with phosphor. The back of the housing is mounted on one end of the panel bracket, the display screen body and the capacitive touch switch panel are sequentially embedded in the front of the housing, and the glass cover with phosphor is fitted into the front of the housing. The panel bracket includes a substrate, hinge arms, and a patch. One end of the hinge arm is hinged to the substrate via a pin, and the other end is hinged to the patch via a pin. The hinge arms are located at the left and right ends of the substrate and have a hollow design. The capacitive touch switch panel consists of a main board and a keypad, and the main board supports a one-key keyboard. The touch keys on the keypad are surrounded by LED halos. Both the capacitive touch switch panel and the glass cover with phosphor are located at the lower front of the housing.

[0041] Among them, the glass cover 5 with fluorescent powder can serve as an indicator at night to avoid not being able to find the switch. Fluorescent powder, commonly known as luminous powder, is usually divided into two categories: photoluminescent powder with energy storage and luminous powder with radioactivity. Photoluminescent powder with energy storage stores light energy after being exposed to natural light, fluorescent light, ultraviolet light, etc., and slowly releases it in the form of fluorescence after the light exposure stops. Therefore, it can still be seen to glow at night or in the dark, and the duration can last for several hours to more than ten hours.

[0042] In other embodiments, the screw 304 and the pressure plate 400 are rotatably mounted via bearings, and a limiting assembly is provided between the pressure plate 400 and the main body 100. This limiting assembly consists of a limiting rod and a limiting hole. The limiting hole is formed on the main body 100, the upper end of the limiting rod is movably inserted into the limiting hole, and the lower end of the limiting rod is fixed to the top of the pressure plate 400. Through the cooperation of the limiting rod and the limiting hole, the angle of the pressure plate 400 can be limited, preventing it from rotating with the screw 304.

[0043] In some other embodiments, a motor controller is connected between the control board and the motor, and the control board controls the motor to rotate in both directions via the motor controller.

[0044] In other embodiments, the pressure plate 400 can be configured as a planar structure, an arc-shaped structure, or other structures. A suitable pressure plate can be replaced according to the actual needs of use. For example, an arc-shaped structure can be used for limbs, while a planar structure can be used for the torso.

[0045] In other embodiments, both the pressure plate and the main body have wire holes to prevent the connection cables between the sensor and the control board from being laid.

[0046] In some other embodiments, a rubber plug is installed in the charging port for dust and water protection.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
