Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a compression nursing auxiliary device for catheter intervention. Background Art

[0002] After the catheter intervention in the internal medicine department of the existing technology center is completed, medical staff usually press on the sutured wound of the cardiology patient to stop bleeding until the wound stops bleeding. Since the medical staff consumes a lot of physical strength during the operation, the long-term pressing force is insufficient, which affects the compression effect of the wound.

[0003] To this end, the Chinese patent with publication number "CN114403972A" announced "A Compression Nursing Assistance Device for Catheter Intervention", whose main structure includes a bracket, and the right wall at the lower end of the bracket is symmetrically structured with two positioning blocks fixedly provided. The middle part of the positioning block at the lower end is threadedly connected to a fastening wheel through a threaded hole, and the top surface of the fastening wheel is fixed with an anti-slip pad. The compression nursing auxiliary device for catheter intervention installs the bracket on the edge of a hospital bed or an operating table through the positioning block. The screw drives the trapezoidal block to slide along the trapezoidal groove. The slider is engaged with the arc-shaped teeth to complete the fixation. The rotating crank drives the worm to engage and transmit to the worm wheel to rotate, so that the rope moves and the movable block slides along the cross bar, so that the round block presses on the patient's postoperative sutured wound, which makes it convenient to press and stop bleeding on the sutured wound of cardiology patients. The pressing force and tilt angle are flexible and convenient to adjust, and it is not easy to slip or shake. The pressing stability is high, which facilitates the compression of postoperative wounds.

[0004] However, when the above-mentioned catheter intervention compression care auxiliary device is actually used, since the components are rigidly connected, it does not have any buffering function, which will cause the pressure block to contact the patient's wound in a hard contact manner, and it is very likely to cause secondary damage due to the hard contact.

The bottom fixed base plate 1 is fixedly installed in the working area and used in conjunction with a hydraulic device, and the liquid circuit of the hydraulic device and the liquid circuit channel 45 are connected through a pipeline.

[0024] To adjust the position of the pressure block 515, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4, it is necessary to set up a hydraulic telescopic height adjustment mechanism 4, which is provided with a No. 1 vertical hollow column 41 fixedly mounted on the upper surface of the bottom fixed base plate 1 and hollow inside, a piston body 47 placed inside the No. 1 vertical hollow column 41 and producing an upward movement effect under the pressure of the liquid, and a No. 1 telescopic rod 48 that moves with the piston body 47 and can drive the top connecting base plate 2 to move. Start the hydraulic equipment, and the liquid enters the liquid reserved chamber 44 along the liquid circuit channel 45, and produces an upward force on the piston body 47. When the force is greater than the elastic pressure of the No. 1 coil spring 49, the piston body 47 will drive the top connecting base plate 2 to move upward, thereby driving the pressure block 515 to move upward, and the elastic strength of the No. 1 coil spring 49 will simultaneously form resistance to the liquid pressure. With the cooperation of this resistance, when the liquid amount remains stable, the pressure block 515 can be kept stable, thereby realizing the adjustment of the position of the pressure block 515. By using this principle, the pressure block 515 is made to contact the patient's wound.

At this time, the rotating cap 512 is manually rotated to drive the external threaded rod 516 to rotate. Due to the connection relationship of the threaded structure, the upper movable plate 511 will move longitudinally, thereby changing the distance between the lower movable plate 510 and the upper movable plate 511, controlling the elastic strength of the No. 2 coil spring 513, and thus controlling the pressing force of the pressing block 515 on the wound.

[0027] For the specific structure of the force-adjustable pressing mechanism 5, please refer to Figure 5 and Figure 6, including an annular mounting shell 51 and a No. 2 vertical hollow column 56, the middle part of the outer circumference of the annular mounting shell 51 is provided with an annular fixing groove 52 fixedly mounted in the component fixing port 3, the center of the annular mounting shell 51 is provided with a hemispherical cavity 53 with both the top and bottom ends being open, the middle area of the No. 2 vertical hollow column 56 is provided with a spherical body structure 54 which is an integral structure with it and mounted inside the hemispherical cavity 53, the spherical body structure 54 is embedded with an annular brake drum 55 on the periphery of the middle area of the hemispherical cavity 53, the interior of the No. 2 vertical hollow column 56 is provided with a No. 2 component movable cavity 57, the bottom and top ends of the No. 2 component movable cavity 57 are respectively provided with a No. 2 rod body through-hole 58 and an internal threaded hole 59, the interior of the No. 2 component movable cavity 57 is provided with a lower movable plate 510 located below and an upper movable plate 511 located above, the lower movable plate 510 and the upper movable plate A No. 2 coil spring 513 in a compressed state is placed between the plates 511, and a No. 2 telescopic rod 514 is fixedly installed at the bottom end of the lower movable plate 510, which passes through the No. 2 rod body through-hole 58 and has a pressure block 515 fixedly installed at the bottom end. The upper end face of the upper movable plate 511 is fixedly installed with an externally threaded rod 516 which passes through the internal threaded hole 59 and has a rotating cap 512 installed on the top. The externally threaded rod 516 is connected to the rod body located inside the internal threaded hole 59 through a threaded structure, and the annular brake drum 55 generates friction resistance to the angular rotation of the spherical structure 54, and the friction resistance is sufficient to make the No. 2 vertical hollow column 56 in a stationary state during operation. The structural shape of the cross section of the No. 2 rod body through-hole 58 is consistent with the structural shape of the cross section of the No. 2 telescopic rod 514, both of which are polygonal structures, and the structural dimensions of the cross section of the No. 2 rod body through-hole 58 match the structural dimensions of the cross section of the No. 2 telescopic rod 514.

[0028] When in use, the bottom fixed base plate 1 is fixedly installed in the working area and used in conjunction with a hydraulic device. The liquid circuit of the hydraulic device and the liquid circuit channel 45 are connected through a pipeline, and the hydraulic device is started. The liquid enters the liquid reserved chamber 44 along the liquid circuit channel 45 and generates an upward force on the piston body 47. When the force is greater than the elastic pressure of the No. 1 coil spring 49, the piston body 47 will drive the top connecting base plate 2 to move upward, thereby driving the pressure block 515 to move upward. The elastic strength of the No. 1 coil spring 49 will simultaneously form resistance to the liquid pressure. With the cooperation of this resistance, when the amount of liquid remains stable, the pressure block 515 can be kept stable, thereby realizing the adjustment of the position of the pressure block 515. By using this principle, the pressure block 515 is made to contact the patient's wound.

[0029] Manually rotate the rotating cap 512 to drive the external threaded rod 516 to rotate. Due to the connection relationship of the threaded structure, the upper movable plate 511 will move longitudinally, thereby changing the distance between the lower movable plate 510 and the upper movable plate 511, controlling the elastic strength of the No. 2 coil spring 513, and thus controlling the pressing force of the pressure block 515 on the wound.
