Description

Technical Field

[0001] The invention relates to the technical field of distal blood flow monitoring, in particular to a distal blood flow monitoring device for radial artery compression hemostasis. Background Art

[0002] The radial artery is one of the important arteries in the upper limbs of the human body. It is mainly responsible for the blood supply to the radial side of the forearm and hand. The radial artery branches off from the brachial artery and runs down along the radial side of the forearm. Its pulsation can be easily felt on the radial side of the wrist. Due to its relatively superficial location, the radial artery plays an important role in clinical pulse palpation, pulse measurement, and puncture for arterial blood gas analysis.

[0003] However, since the radial artery is an arterial blood vessel, the blood flowing in it will produce a certain pressure and pulsation. When the needle is inserted into the radial artery, this pulsation and pressure may cause a certain impact and shaking on the needle, and then cause the infusion tube softly connected to the needle to shake due to the shaking of the needle, affecting the accuracy of blood flow monitoring. For this reason, we proposed a radial artery compression hemostasis distal blood flow monitoring device. Summary of the invention

[0004] The purpose of the present invention is to provide a radial artery compression hemostasis distal blood flow monitoring device to solve the problems raised in the above background technology.

An internal thread is provided at the center of the fixed plate 1, and the special-shaped fixed plate 1 is threadedly connected to the outer surface of the bidirectional threaded rod through the internal thread at the center. A blood flow sensor is fixedly connected to the bottom of the two special-shaped fixed plates 1, and the two blood flow sensors are mirror-imaged with the limiting protrusion as the center. By arranging the bidirectional threaded rod, the bidirectional threaded rod can drive the two special-shaped fixed plates 1 to move toward each other when rotating counterclockwise, and drive the two blood flow sensors at the bottom to move toward the side close to each other, so as to fix the infusion tube at the center and monitor the inside of the infusion tube while fixing it.

[0007] Furthermore, an auxiliary component is arranged at the center of the outer surface of the front side of the clamping component, and the auxiliary component includes an auxiliary component housing, a motor is fixedly connected to the bottom of the outer surface of the front side of the auxiliary component housing, the rear side of the auxiliary component housing is fixedly connected to the front side of the clamping component housing, the front side of the bidirectional threaded rod extends through the interior of the auxiliary component housing, and pulleys are arranged on the top and bottom of the auxiliary component housing, and the two pulleys are mirror-imaged with the auxiliary component housing as the center, and belts are sleeved on the outer surfaces of the two pulleys, and the two pulleys are connected to each other through belt transmission, the rear side of the pulley located above is fixedly connected to the front side of the bidirectional threaded rod, and the pulley located below is fixedly connected to the front side of the bidirectional threaded rod.

[0008] Furthermore, a pressing assembly is provided on both sides of the clamping assembly, and a strapping assembly is provided below the two pressing assemblies. The two strapping assemblies are mirror-imaged with the clamping assembly shell as the center. The two strapping assemblies include a rectangular fixing block. A square hole groove is opened at the center of the two rectangular fixing blocks. Strapping straps are fixedly connected in the square hole grooves of the two rectangular fixing blocks. The two strapping straps are mirror-imaged with the auxiliary assembly shell as the center. By setting up two strapping straps, medical staff can tie the monitoring equipment to the forearm of the monitored person, thereby improving the comfort of the monitored person during wearing and facilitating medical staff to monitor the monitored person for a long time.

[0009] Furthermore, the two pressing components are mirror-imaged with the clamping component shell as the center, and the two pressing components each include a pressing component shell, and pressing plates are arranged on the top and bottom of the inner surface of the pressing component shell. The two pressing plates are mirror-imaged with the pressing component shell as the center, and a semicircular curved surface is arranged on the sides of the two pressing component shells close to each other, and a plurality of pressing springs are fixedly connected to the sides of the two pressing plates away from each other. The plurality of pressing springs are arranged in a horizontal array with the pressing component shell as the center, and the sides of the plurality of pressing springs away from the pressing plates are fixedly connected to the inner surface of the pressing component shell. By setting up two pressing plates, the two pressing plates can clamp the infusion tube from the top and bottom of the infusion tube through the arc surface, and by setting up a plurality of pressing springs, the pressing component can absorb the shaking of the infusion tube to ensure that the infusion tube is always in the center of the device.

[0010] Furthermore, an arc surface is provided on one side of the two blood flow sensors close to each other, and a plurality of square and circular protrusions are fixedly connected to the arc surfaces of the two blood flow sensors. By providing a plurality of square and circular protrusions on the arc surfaces of the blood flow sensors, the friction between the arc surfaces of the two blood flow sensors and the outer surface of the infusion tube can be increased, thereby preventing the infusion tube from falling off the equipment.

[0011] Furthermore, the clamping assembly includes two sliding rods, and the two sliding rods are arranged at the bottom of the bidirectional threaded rod. The front and rear sides of the two sliding rods are fixedly connected to the inner surface of the clamping assembly shell.

Two circular holes are provided at the center of the bottoms of the two special-shaped fixing plates 2. The inner surfaces of the circular holes of the special-shaped fixing plates 2 are slidably connected to the outer surface of the sliding rod. By providing the special-shaped fixing plate 2, the two blood flow sensors can move along the outer surface of the sliding rod through the inner surface of the special-shaped fixing plate 2 when moving, thereby preventing the two blood flow sensors from deflecting during the movement and ensuring the stability of the equipment operation.

[0012] Furthermore, the clamping assembly includes four sliders, which are respectively arranged at the top of two special-shaped fixing plates one and the bottom of two special-shaped fixing plates two, the bottom of the slider located at the top is fixedly connected to the top of the special-shaped fixing plate one, and the top of the slider located at the bottom is fixedly connected to the bottom of the special-shaped fixing plate two, and the top and bottom of the inner surface of the outer shell of the clamping assembly are provided with slide rails, and the two slide rails are mirror-imaged with the blood flow sensor as the center, and the inner surface of the slide rails is slidably connected to the outer surfaces of the four sliders. By setting the sliders, the two blood flow sensors can slide along the slide rails opened at the top and bottom of the outer shell of the clamping assembly through the sliders fixedly connected at the top and bottom when moving, thereby further preventing the two blood flow sensors from deviating when sliding, thereby ensuring the stability of the equipment operation.

[0013] Furthermore, the bottom of the inner surface of the strapping strap located on the rear side is fixedly connected with Velcro 1, and the bottom of the outer surface of the strapping strap located on the front side is fixedly connected with Velcro 2. The top of Velcro 1 and the bottom of Velcro 2 cooperate with each other. By arranging Velcro 1 and Velcro 2, the front and rear sides of the strapping strap can be quickly connected together, and they can be separated by pulling Velcro 1 and Velcro 2 again, so that medical staff can more conveniently fix the equipment to the forearm of the monitored person.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention provides a clamping assembly, specifically, by rotating a bidirectional threaded rod, so that the outer surface of the bidirectional threaded rod drives two special-shaped fixing plates to move through a threaded connection. When the bidirectional threaded rod rotates counterclockwise, the two blood flow sensors are driven to move toward each other through the special-shaped fixing plate. In this way, the movement of the two blood flow sensors can be controlled by rotating the bidirectional threaded rod. When the two blood flow sensors are close to each other, the infusion tube at the center is fixed to prevent the infusion tube from shaking due to the pulse of the radial artery, thereby ensuring the accuracy of blood flow monitoring.

[0016] (2) The present invention sets an auxiliary component. Specifically, when the motor is started, the motor drives the pulley at the bottom to rotate through the coupling. When the bottom pulley rotates, the top pulley is driven to rotate through the belt, so that the two pulleys can rotate synchronously. When the top pulley rotates, it drives the fixedly connected bidirectional threaded rod to rotate together. In this way, the rotation of the two pulleys can be controlled by the auxiliary component housing, and then the rotation of the bidirectional threaded rod can be controlled, so that medical staff can accurately control the movement of the blood flow sensor, prevent the equipment from damaging the infusion tube, and ensure the subsequent blood monitoring.

[0017] (3) The present invention provides a strapping assembly, specifically, the device is placed near the radial side or thumb side of the forearm of the monitored person to be monitored, so that the bottoms of the two rectangular fixing blocks fit against the patient's forearm, and then the strapping belts on both sides of the rectangular fixing blocks are pulled to tie the strapping belts on the forearm of the monitored person. Since the forearm is an easily accessible and relatively flat part, the device can be conveniently worn on the monitored person, and can also improve the comfort of the monitored person during the wearing process, making it convenient for medical staff and the monitored person to perform continuous monitoring.
