Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent ENBD nursing quality sensitive indicator early warning system and an implementation method thereof. Background Art

[0002] ENBD, or endoscopic nasobiliary drainage, is suitable for acute suppurative obstructive cholangitis, bile duct obstruction caused by primary or secondary tumors, bile duct obstruction caused by hepatobiliary stones, and is also used to prevent common bile duct stone incarceration, biliary pancreatitis, benign bile duct stenosis, traumatic or iatrogenic bile fistula, sclerosing cholangitis, etc.

[0003] In the postoperative care of endoscopic nasobiliary drainage, it is necessary to prevent the indwelling catheter from falling off to ensure that the bile can flow out smoothly. The conventional way to fix the catheter is to stick the catheter to the patient's face with tape. However, during the patient's daily activities (such as turning over, etc.), the catheter is easily pulled and causes the catheter to fall off. In the prior art, there is no device to warn whether the catheter has fallen off. When the patient's family, caregivers, and medical staff are monitoring, it is difficult to observe whether the catheter has fallen off at all times, which is quite energy-consuming, so further improvements can be made.

[0017] S1. The liquid level inside the drainage bag is monitored by a liquid level sensor. When the liquid level inside the drainage bag reaches a preset level, the liquid level sensor transmits a signal to the controller and sounds an alarm through a buzzer to remind medical staff to replace the drainage bag.

[0018] S2. The distance sensor is used to monitor whether the rotating ring is rotating.

After the fixed bar and the slider are staggered, under the elastic action of the second spring, the slider is inserted between the two trapezoidal plates. As the trapezoidal plate continues to move upward, the slider blocks the rotating wheel, causing the rotating wheel to move downward relative to the trapezoidal plate, thereby causing the sliding column to slide along the inclined groove, so that the two rotating wheels approach each other and squeeze the drainage tube, thereby sealing the opening at the tail end of the drainage tube.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1-Figure 10, an intelligent ENBD nursing quality sensitive indicator early warning system, including a drainage tube 100 and a head-mounted assembly 300, the tail end of the drainage tube 100 is connected to a drainage bag 200, and the drainage tube 100 is connected to the drainage bag 200 by plugging and unplugging. A clamping assembly 400 is fixedly installed on the right side of the head-mounted assembly 300, and the clamping assembly 400 is clamped on the surface of the drainage tube 100 to fix the drainage tube 100 to prevent the drainage tube 100 from falling off. A distance sensor 500 is arranged inside the clamping assembly 400, and the distance sensor 500 is used to monitor the movement of the drainage tube 100 relative to the clamping assembly 400. The distance sensor 500 is connected to a data line 501, and the other end of the data line 501 is connected to a controller 600. When the drainage tube 100 moves relative to the clamping assembly 400, the distance sensor 500 transmits a signal to the controller 600 through the data line 501, and then sends an early warning signal through the controller 600. It also includes a storage box 700, which is hung on the bed, and the controller 600 is fixedly installed on the side of the storage box 700. A winding assembly 800 is arranged inside the storage box 700, and the data cable 501 is wound on the surface of the winding assembly 800. A tail end stopper 900 is arranged inside the storage box 700, and the tail end stopper 900 is used to limit the tail end of the drainage tube 100. A plurality of arc buckles 502 are fixedly installed on the surface of the data cable 501, and the drainage tube 100 is clamped in the arc buckle 502. The drainage tube 100 and the data cable 501 are fitted together to prevent the two from being entangled.

[0049] See also Figure 1-Figure 10 The controller 600 is provided with a display screen 601 and a buzzer 602. The controller 600 is electrically connected to a liquid level sensor 603. The liquid level sensor 603 is fixedly mounted on the inner wall of the storage box 700, and the liquid level sensor 603 faces the surface of the drainage bag 200. The drainage bag 200 is fixed inside the storage box 700, and the liquid level inside the drainage bag 200 is monitored by the liquid level sensor 603. When the liquid level inside the drainage bag 200 is high, the liquid level sensor 603 transmits a signal to the controller 600, and the buzzer 602 sends a warning signal to remind medical staff to replace the drainage bag 200.

[0050] See also Figure 3 The head-mounted assembly 300 includes a mesh 301 that fits on the patient's head. A connecting belt 1 302 is sewn on the left bottom of the mesh 301. A metal ring 303 is fixed at the bottom of the connecting belt 1 302. A connecting belt 2 304 is sewn on the right bottom of the mesh 301. Positioning holes 305 are arranged in an array along the length direction of the connecting belt 2 304. A positioning column 306 is fixedly installed on the surface of the connecting belt 2 304. The connecting belt 2 304 passes through the metal ring 303, and the positioning column 306 is inserted into the positioning hole 305. Thus, the clamping assembly 400 is stably mounted on the side of the patient's head through the mesh 301, the connecting belt 1 302 and the connecting belt 2 304.

[0051] See also Figure 4-Figure 6 The clamping assembly 400 includes a fixed clamping plate 401 fixedly mounted on the right side of the connecting belt 2 304, a movable clamping plate 402 is hinged at the bottom of the fixed clamping plate 401, and a connecting buckle 403 is arranged on the top of the fixed clamping plate 401 and the movable clamping plate 402. The fixed clamping plate 401 and the movable clamping plate 402 are both provided with an L-shaped groove 404 on the opposite side, and the cross section of the L-shaped groove 404 is semicircular, and the drainage tube 100 passes through the L-shaped groove 404. Thus, the drainage tube 100 is placed in the L-shaped groove 404 on the surface of the fixed clamping plate 401, and then the movable clamping plate 402 is deflected to make the movable clamping plate 402 fit on the surface of the fixed clamping plate 401, and the fixed clamping plate 401 and the movable clamping plate 402 are limited by the connecting buckle 403. The fixed clamping plate 401 and the movable clamping plate 402 stably clamp and fix the drainage tube 100. Furthermore, the L-shaped groove 404 is designed in an L-shape, so that the drainage tube 100 is arranged in a bent shape between the fixed clamping plate 401 and the movable clamping plate 402, thereby preventing the drainage tube 100 from being pulled.

[0052] See also Figure 4-Figure 6 The surface of the fixed clamp 401 is provided with a circular groove 405, which is connected to the inner side of the turning of the L-shaped groove 404. A fixed shaft 406 is fixedly installed at the center of the circular groove 405. A swivel 407 is rotatably connected to the outer side of the fixed shaft 406. The diameter of the circular groove 405 is larger than the inner diameter of the turning of the L-shaped groove 404, so that the swivel 407 can be moved along to the inside of the L-shaped groove 404. The circumferential surface of the swivel 407 fits the inner side of the corner of the drainage tube 100. The circumferential surface of the swivel 407 is provided with an embedded groove 408, so that the swivel 407 is pressed on the surface of the drainage tube 100, further inhibiting the drainage tube 100 from being pulled. The fixed clamp 401 is provided with an installation groove at the top wall of the circular groove 405, and an embedded block 409 is slidably connected in the installation groove. A spring 410 is fixedly installed between the top of the embedded block 409 and the top wall of the installation groove, and the embedded block 409 abuts in the embedded groove 408. Through the elasticity of the spring 1 410, the free end of the insert 409 is inserted into the insert groove 408, which inhibits the rotation of the rotating ring 407 and further inhibits the drainage tube 100 from being pulled. The distance sensor 500 is embedded in the fixed clamping plate 401 and faces the circumferential surface of the rotating ring 407. The data line 501 passes through the bottom of the fixed clamping plate 401. When the rotating ring 407 rotates, the insert groove 408 rotates to face the distance sensor 500, so that the distance sensor 500 transmits a signal to the controller 600.

[0053] See also Fig. 9Two sets of U-shaped plates 701 are fixedly installed on the bottom wall of the storage box 700. The U-shaped plates 701 are U-shaped when viewed from above. The edges of the drainage bag 200 are inserted into the U-shaped plates 701. The surface of the U-shaped plates 701 is provided with threaded holes. The U-shaped plates 701 are connected with bolts 702 through the threaded holes. The bolts 702 abut against the drainage bag 200, thereby stably fixing the drainage bag 200 inside the storage box 700. A hook 703 is fixedly installed on the left side of the storage box 700, and the storage box 700 is hung on the bed through the hook 703.

[0054] See also Figure 7-Figure 8 The winding assembly 800 includes a hollow drum 801, and a connecting tube 802 is fixedly installed at both ends of the hollow drum 801. The outer wall of the connecting tube 802 is sleeved with a support seat 803, and the support seat 803 is fixedly installed on the inner wall of the storage box 700, and the connecting tube 802 and the hollow drum 801 are supported by the support seat 803. A turntable 804 is fixedly installed at the end of the right connecting tube 802, and a motor 805 is fixedly installed at the center of the turntable 804. The motor 805 is electrically connected to the controller 600. The motor 805 is controlled to start and stop by the controller 600. After the motor 805 is started, the hollow drum 801 is driven to rotate. The data line 501 is wound on the surface of the hollow drum 801, and the data line 501 passes through the outer wall of the connecting tube 802 on the right to the inside, and passes through the inside of the hollow drum 801. Therefore, after the hollow drum 801 rotates, the data cable 501 can be released, and the end of the data cable 501 close to the controller 600 can be prevented from being rolled up on the hollow drum 801 when the hollow drum 801 rotates.

[0055] See also Figure 9-10 The tail end stopper 900 includes two sets of horizontal plates 901 fixedly installed inside the storage box 700, two square tubes 902 are fixedly installed between the two sets of horizontal plates 901, the openings of the two square tubes 902 are opposite, a slider 903 is slidably connected inside the square tube 902, a second spring 904 is fixedly installed between the slider 903 and the inner wall of the square tube 902, and the free end of the slider 903 is V-shaped. Due to the elasticity of the second spring 904, the two sliders 903 have a tendency to approach each other. Two sets of trapezoidal plates 905 are sandwiched between the two sets of horizontal plates 901, and the tops of the two sets of trapezoidal plates 905 are fixedly connected by two fixing strips 906, and the bottom of the free end of the slider 903 is attached to the fixing strip 906. Two inclined grooves 907 are provided on the trapezoidal plate 905, and the spacing between the two inclined grooves 907 gradually decreases from top to bottom. Two groups of rotating wheels 908 are clamped between the two groups of trapezoidal plates 905. Sliding columns 909 are fixedly installed at the centers of both sides of the rotating wheels 908. The sliding columns 909 are slidably connected in the inclined grooves 907. The two groups of rotating wheels 908 are clamped on both sides of the drainage tube 100. An annular flange is provided on the tail end of the drainage tube 100, and the annular flange abuts against the bottom of the trapezoidal plate 905.

[0056] The rotating wheel 908 is clamped on both sides of the tail end of the drainage tube 100, and the annular flange of the tail end of the drainage tube 100 abuts against the bottom of the trapezoidal plate 905, so that when the slider 903 limits the fixing bar 906, the drainage tube 100 is inhibited from moving upward, so that the tail end of the drainage tube 100 remains inserted in the drainage bag 200. When the drainage tube 100 is pulled, the annular flange of the drainage tube 100 pushes the trapezoidal plate 905 upward, and the fixing bar 906 squeezes the slider 903. When the fixing bar 906 and the slider 903 are offset, the slider 903 rebounds under the elastic action of the spring 2 904, and fits on the top of the rotating wheel 908 to limit the rotating wheel 908. As the drainage tube 100 and the trapezoidal plate 905 move upward, the rotating wheel 908 moves downward relative to the trapezoidal plate 905, and the sliding column 909 slides along the inclined groove 907, so that the two sets of rotating wheels 908 are clamped on the surface of the drainage tube 100 to seal the bottom end of the drainage tube 100. After the drainage tube 100 is separated from the drainage bag 200, the bottom end of the drainage tube 100 remains sealed to prevent the bile in the drainage tube 100 from overflowing. As the trapezoidal plate 905 continues to move upward, the rotating wheel 908 squeezes the slider 903, and the slider 903 retracts into the square tube 902, so that the slider 903 and the rotating wheel 908 are staggered.

[0057] The specific steps of the implementation method of this system are as follows:

[0058] S1. The liquid level inside the drainage bag 200 is monitored by the liquid level sensor 603. When the liquid level inside the drainage bag 200 reaches a preset liquid level, the liquid level sensor 603 transmits a signal to the controller 600 and sounds an alarm through the buzzer 602 to remind the medical staff to replace the drainage bag 200.

[0059] S2. The distance sensor 500 is used to monitor whether the rotating ring 407 rotates. When the drainage tube 100 is pulled, the rotating ring 407 rotates under the action of friction, and cooperates with the embedded grooves 408 arranged in an array on the surface of the rotating ring 407. When the embedded grooves 408 on the surface of the rotating ring 407 rotate to face the distance sensor 500, the distance between the end of the distance sensor 500 and the circumferential surface of the rotating ring 407 changes, and the distance sensor 500 transmits a signal to the controller 600, and the buzzer 602 sounds an alarm to remind the patient;

[0060] S3, when the rotating ring 407 rotates relative to the fixed shaft 406, the embedded block 409 is squeezed by the side wall of the embedded groove 408, and the embedded block 409 retracts into the installation groove. Then, under the elastic action of the spring 1 410, it abuts against the embedded groove 408 again. When the rotating ring 407 rotates at a large angle, the embedded block 409 collides with the inner wall of the embedded groove 408, and emits a continuous sound to remind the patient;

[0061] S4. At the same time, the controller 600 controls the motor 805 to start, driving the hollow drum 801 to rotate, and releasing the data cable 501 wound on the hollow drum 801 to prevent the data cable 501 from being stretched and damaged during the process of pulling the drainage tube 100;

[0062] S5.
