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, and bile duct obstruction caused by hepatolithiasis. It is also used to prevent common bile duct stone impaction, 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 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 caused to fall off. In the prior art, there is no device to detect whether the catheter has fallen off and to provide an early warning. 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, and further improvements can be made.

[0050] Please refer to Figure 3 Head assembly 300 includes the gauze net 301 of adhering in the patient's head, and the left side bottom of gauze net 301 is sewn with connecting band one 302, and the bottom of connecting band one 302 is fixed with metal ring 303, and the right side bottom of gauze net 301 is sewn with connecting band two 304, and a plurality of positioning holes 305 are formed on the surface of connecting band two 304 along the length direction of connecting band two 304, and a positioning column 306 is fixedly installed on the surface of connecting band two 304, and connecting band two 304 passes through metal ring 303, and positioning column 306 is inserted into positioning hole 305. So, through the cooperation of gauze net 301, connecting band one 302 and connecting band two 304, clamping assembly 400 is stably installed on the side of the patient's head.

[0051] Please refer to Figures 4-6 The clamping assembly 400 comprises a fixed clamping plate 401 fixedly installed on the right side of the connecting belt 304, and the bottom of the fixed clamping plate 401 is hingedly connected with a movable clamping plate 402. The top of the fixed clamping plate 401 and the movable clamping plate 402 is provided with a connecting buckle 403, and the opposite side of the fixed clamping plate 401 and the movable clamping plate 402 is provided with an L-shaped groove 404. The L-shaped groove 404 is in a semicircular cross-section, 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 be attached to 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. 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, and the drainage tube 100 is inhibited from being pulled.

[0052] Please refer to Figures 4-6 The surface of the fixed clamping plate 401 is provided with a circular groove 405, and the circular groove 405 is connected to the inner side of the bend of the L-shaped groove 404. The center of the circular groove 405 is fixedly installed with a fixed shaft 406, and the outer side of the fixed shaft 406 is rotatably connected with a rotating ring 407. The diameter of the circular groove 405 is larger than the diameter of the inner side of the bend of the L-shaped groove 404, so that the rotating ring 407 is located inside the L-shaped groove 404. The circumferential surface of the rotating ring 407 is attached to the inner side of the corner of the drainage tube 100, and the circumferential surface of the rotating ring 407 is arrayed with a plurality of embedding grooves 408. Thus, the rotating ring 407 is pressed on the surface of the drainage tube 100, further inhibiting the drainage tube 100 from being pulled. The fixed clamping plate 401 is provided with a mounting groove at the top wall of the circular groove 405, and the mounting groove is slidably connected with an embedding block 409. The top end of the embedding block 409 and the top wall of the mounting groove are fixedly installed with a spring 410, and the embedding block 409 abuts against the embedding groove 408. The free end of the embedding block 409 is inserted into the embedding groove 408 by the elasticity of the spring 410, so as to inhibit the rotating ring 407 from rotating, further inhibiting 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, and the data line 501 passes out from the bottom of the fixed clamping plate 401. When the rotating ring 407 rotates, the embedding groove 408 rotates to face the distance sensor 500, so that the distance sensor 500 transmits a signal to the controller 600.

[0053] Please refer to Figure 9The bottom wall of the storage box 700 is fixedly provided with two groups of U-shaped plates 701. The U-shaped plates 701 are in a U-shaped view. The edges of the two sides of the drainage bag 200 are inserted into the U-shaped plates 701. Threaded holes are formed in the surfaces of the U-shaped plates 701. The U-shaped plates 701 are connected with bolts 702 through the threaded holes. The bolts 702 abut against the drainage bag 200, so that the drainage bag 200 is stably fixed in the inside of the storage box 700. The left side of the storage box 700 is fixedly provided with a hook 703. The storage box 700 is hung on the hospital bed through the hook 703.

[0054] Please refer to Figures 7-8 The winding assembly 800 comprises a hollow rotating drum 801. The two ends of the hollow rotating drum 801 are fixedly provided with connecting pipes 802. The outer walls of the connecting pipes 802 are sleeved with support seats 803. The support seats 803 are fixedly installed on the inner walls of the storage box 700 and support the connecting pipes 802 and the hollow rotating drum 801 through the support seats 803. The end of the right connecting pipe 802 is fixedly provided with a rotating disc 804. The rotating disc 804 is fixedly installed at the center of the hollow rotating drum 801. An electric machine 805 is fixedly installed at the center of the rotating disc 804 and is electrically connected with the controller 600. The electric machine 805 is started and stopped through the controller 600. After the electric machine 805 is started, the hollow rotating drum 801 is driven to rotate. The data line 501 is wound on the surface of the hollow rotating drum 801. The data line 501 penetrates through the outer wall of the right connecting pipe 802 to the inside and passes through the inside of the hollow rotating drum 801. Thus, after the hollow rotating drum 801 rotates, the data line 501 can be released. When the hollow rotating drum 801 rotates, the end of the data line 501 close to the controller 600 is prevented from being wound on the hollow rotating drum 801.

[0055] Please refer to Figures 9-10 The tail end limiting piece 900 comprises two groups of horizontal plates 901 fixedly installed in the inside of the storage box 700. Two square cylinders 902 are fixedly installed between the two groups of horizontal plates 901. The openings of the two square cylinders 902 are opposite. Sliding blocks 903 are slidingly connected in the square cylinders 902. Spring two 904 is fixedly installed between the sliding blocks 903 and the inner walls of the square cylinders 902. The free ends of the sliding blocks 903 are in a V-shaped view. The elasticity of the spring two 904 enables the two sliding blocks 903 to have a mutual approaching trend. Two groups of trapezoidal plates 905 are clamped between the two groups of horizontal plates 901. The two groups of trapezoidal plates 905 are fixedly connected through two fixed bars 906 at the top ends. The free end bottoms of the sliding blocks 903 are attached to the fixed bars 906. Two inclined grooves 907 are formed in the trapezoidal plates 905. The intervals of the two inclined grooves 907 gradually decrease from top to bottom. Two groups of rotating wheels 908 are clamped between the two groups of trapezoidal plates 905. The two groups of rotating wheels 908 are fixedly installed with sliding columns 909 at the centers of the two sides. The sliding columns 909 are slidingly connected in the inclined grooves 907. The two groups of rotating wheels 908 are clamped on the two sides of the drainage tube 100. An annular flange is arranged on the tail end of the drainage tube 100. The annular flange abuts against the bottom of the trapezoidal plate 905.

[0056] The rotating wheel 908 clamps onto 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 the bottom of the trapezoidal plate 905. This prevents the drainage tube 100 from moving upward when the slider 903 limits the fixed bar 906, thereby keeping the tail end of the drainage tube 100 inserted into 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 fixed bar 906 presses the slider 903. When the fixed bar 906 and the slider 903 are offset, the slider 903 rebounds under the elastic action of the second spring 904 and abuts against the top of the rotating wheel 908, limiting the rotating wheel 908. As the drainage tube 100 and trapezoidal plate 905 move upward, the runners 908 move downward relative to the trapezoidal plate 905. The slide post 909 slides along the inclined groove 907, clamping the two sets of runners 908 against the surface of the drainage tube 100 and sealing 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, preventing bile from overflowing. As the trapezoidal plate 905 continues to move upward, the runners 908 squeeze the slider 903, causing it to retract into the square tube 902, causing the slider 903 to be offset from the runners 908.

[0057] The specific steps for implementing the 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 level, the liquid level sensor 603 transmits a signal to the controller 600 and sounds an alarm through the buzzer 602 to remind medical staff to replace the drainage bag 200.

[0059] S2. The distance sensor 500 monitors whether the rotating ring 407 is rotating. When the drainage tube 100 is pulled, the rotating ring 407 rotates due to friction, cooperating 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. The distance sensor 500 transmits a signal to the controller 600, and the buzzer 602 sounds an alarm to alert the patient.

[0060] S3. When the rotating ring 407 rotates relative to the fixed shaft 406, the insert 409 is squeezed by the side wall of the embedding groove 408, and the insert 409 retracts into the installation groove. Then, under the elastic action of the spring 1 410, it abuts against the embedding groove 408 again.

8. The intelligent ENBD nursing quality sensitive indicator early warning system according to claim 7 is characterized in that: The specific steps for implementing the system are as follows: 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), reminding medical staff to replace the drainage bag (200); 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 toward the distance sensor (500), the distance between the end of the distance sensor (500) and the circumferential surface of the rotating ring (407) changes. The distance sensor (500) transmits a signal to the controller (600), and the buzzer (602) sounds an alarm to remind the patient; 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) is retracted into the installation groove. Thereafter, 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), emitting a continuous sound to remind the patient; 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), so as to prevent the data cable (501) from being stretched and damaged during the process of pulling the drainage tube (100); S5. When the drainage tube (100) is pulled, the narrow annular flange at the tail end of the drainage tube (100) lifts the trapezoidal plate (905) upward, the trapezoidal plate (905) moves upward, and the fixed bar (906) squeezes the slider (903), so that the slider (903) retracts into the inside of the square tube (902). After the fixed bar (906) and the slider (903) are staggered, under the elastic action of the second spring (904), the slider (903) is inserted between the two trapezoidal plates (905). As the trapezoidal plate (905) continues to move upward, the slider (903) blocks the rotating wheel (908), so that the rotating wheel (908) moves downward relative to the trapezoidal plate (905), thereby causing the sliding column (909) to slide along the inclined groove (907), so that the two rotating wheels (908) approach each other, squeezing the drainage tube (100), thereby sealing the tail end opening of the drainage tube (100).
