In some embodiments of the present application, the hanging handle 2 comprises two L-shaped handle rods, the vertical ends of the handle rods are movably connected to the middle of the top of the hanger body 1, and the horizontal ends of the two handle rods can be snapped together.

[0029] A hook 7 is movably connected to the middle of the bottom of the hanger body 1. A weighing alarm structure is provided in the inner cavity of the hanger body 1. The weighing alarm structure includes a fixed block 19 fixedly connected to the inner cavity of the hanger body 1 and a driven block 23 movably connected to the hanger body 1.

[0030] The top of the driven block 23 is fixedly connected with a slider 24, and the top of the inner cavity of the hanger body 1 is fixed with a slide groove adapted by the slider 24. Under the action of external force, the driven block 23 can move along the direction of the slide groove. The middle part of the top of the slider 24 is fixedly connected with an electromagnet 2 31. When the electromagnet 2 31 is in a powered state, the electromagnet 2 31 and the slide groove are in a state of magnetic attraction. In some embodiments of the present application, an iron sheet is fixed on the top of the inner cavity of the slide groove. Through the setting of the electromagnet 2 31, when the electromagnet 2 31 is in a powered state, the position of the driven block 23 can be fixed.

[0031] The end of the driven block 23 close to the fixed block 19 is fixedly connected with a variable resistor 28, the other end of the driven block 23 is movably connected with a ball screw 29, the outer ring of the ball screw 29 is threadedly connected with a ball nut 27, and the end of the driven block 23 away from the fixed block 19 is fixedly connected with a rotating motor 25, and the end of the output shaft of the rotating motor 25 is fixedly connected to the end of the ball screw 29 through a reducer. Through the setting of the rotating motor, the rotation of the rotating motor 25 can drive the ball screw 29 fixedly connected thereto to rotate, and when the ball screw 29 rotates, the ball nut 27 threadedly connected to the ball screw 29 can move in the direction where the ball screw 29 is located.

[0032] A positioning block 30 is movably connected to the top of the ball nut 27, and a rotating motor 26 is fixed to the top of the ball nut 27. The end of the output shaft of the rotating motor 26 is fixedly connected to the positioning block 30 via a reducer. Through the setting of the rotating motor 26, the rotation of the rotating motor 26 can drive the positioning block 30 fixedly connected thereto to rotate. The positioning block 30 is made of insulating material, and the material of the positioning block 30 can be ceramic. When the positioning block 30 is in a vertical state, the positioning block 30 is located above the ball nut 27.

[0033] The above-mentioned rotating motor 25 and rotary motor 26 are both self-locking motors. In some embodiments of the present application, the structure of the rotating motor 25 is the same as the structure of the self-locking motor disclosed in the authorized patent with application number CN202122932329.X. The model of the rotary motor 26 can be BLDC4260+GA.

[0034] The top of the fixed block 19 is fixedly connected to the positioning rod 14, and the outer ring of the positioning rod 14 is movably connected to the driven rod 20. The end of the driven rod 20 close to the fixed block 19 is fixedly connected to the slider of the variable resistor 28 through the pushing block 21. Under the action of external force, when the driven rod 20 moves along the direction of the positioning rod 14, the driven rod 20 can drive the slider of the variable resistor 28 to move through the pushing block 21, and the resistance value of the variable resistor 28 can change. The present application changes the resistance value of the variable resistor 28 to change the excitation voltage on the circuit where the variable resistor is located, and outputs a changing analog signal; the signal is amplified by the amplification circuit and output to the analog-to-digital converter, thereby converted into a digital signal that is easy to process and output to the controller, thereby realizing weighing.

[0035] The other end of the pushing block is fixedly connected to a pressure sensor 22, and the other end of the pushing block is located between the ball screw 29 and the variable resistor 28. When the positioning block 30 is in a vertical state, the other end of the pushing block does not contact the positioning block 30. When the positioning block 30 rotates 90 degrees, the positioning block 30 can intercept the pushing block, which is convenient for the preset weighing weight of the hanger, and according to the value detected by the pressure sensor 22, it can be determined whether the pushing block 21 is in contact with the positioning block 30, and then it can be determined whether the weight of the item hung on the hook 7 is the same as the preset weight.

[0038] From the above description, it can be known that when a heavy object is hung on the hook 7, the hook 7 can drive the movable plate 18 to move through the pull rope 15, and the movable plate 18 can drive the slider of the variable resistor 28 to move through the driven rod 20 to change the resistance value of the variable resistor 28, and can drive the positioning block 30 to move through the ball screw 29, so that the positioning block 30 can be moved to the preset resistance value position of the variable resistor 28. When the pushing block contacts the positioning block 30, the weight of the object hung on the hook 7 is the same as the preset weight of the object, and when the positioning block 30 is located above the ball screw 29, the positioning block 30 will not restrict the hook 7, that is, the hanger can be used as an electronic scale to weigh objects.

[0039] A display screen 3 and a keypad 4 are provided on the front of the hanger body 1 , and the display screen 3 displays the real-time weight and preset weight of the object hung on the hook 7 .

[0040] A drainage tube clamping structure is provided on both sides of the bottom end of the hanger body 1, and the drainage tube clamping structure includes a support seat 5 fixedly connected to the hanger body 1, a vertical groove adapted to the drainage tube is provided in the middle of the support seat 5, a translation groove is provided in the middle of the vertical groove, a clamping block 8 is connected to the inner cavity of the translation groove through a spring 12, an iron rod 11 is fixedly connected to the clamping block 8 on the side close to the hanger body 1, an electromagnet 13 is fixedly connected to the side of the vertical groove close to the hanger body 1, a positioning tube 10 is fixedly connected to the end of the clamping block 8 close to the hanger body 1, the positioning tube 10 is movably connected to the inner cavity of the translation groove, the spring 12 and the iron rod 11 are both located in the inner cavity of the positioning tube 10, and the positioning tube 10 contacts the inner wall of the translation groove. By setting the drainage tube clamping structure, when the electromagnet 13 is in the energized state, the electromagnet 13 and the iron rod 11 are in a state of magnetic attraction. Under the action of the suction force, the clamping block 8 can approach the electromagnet 13. During the movement, the clamping block 8 can squeeze the drainage tube located in the vertical groove to achieve the closure of the drainage tube.

[0041] An elastic pad 9 is fixedly connected to the inner cavity of the vertical groove. The material of the elastic pad 9 can be rubber. Through the provision of the elastic pad 9, the drainage tube clamping structure can adapt to drainage tubes of various sizes, thereby improving the adaptability of the application.

[0042] From the above description, it can be seen that the drainage bag hanger with visual alarm function can be used as a hook to hang on the side of the bed to hang the drainage bag; it can be used as an electronic scale to weigh the weight of items; the weighing weight can be preset to achieve the purpose of real-time weighing of ascites during ascites drainage.

[0043] In some embodiments of the present application, the models of both electromagnet 13 and electromagnet 2 may be LS-P20 / 23S.

[0044] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods.

The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0045] In summary: when the drainage bag hanger with a visual alarm function is used, the staff hangs the hanger at a suitable position, hangs the drainage bag on the hook 7, and clamps the drainage tube in the inner cavity of the vertical groove. After the drainage bag is hung, the hook 7 moves downward under the influence of the gravity of the drainage bag, and the hook 7 drives the movable plate 18 to move through the pull rope 15. The movable plate 18 drives the positioning block 30 to move through the pushing block connected to the driven rod 20, and the positioning block 30 drives the driven block 23 to move to complete the peeling operation. The electromagnet 23 is in an energized state to fix the position of the driven block 23; the staff sets the amount of ascites to be drained according to the temporary doctor's order and displays it on the display screen 3, and the rotating motor 26 drives the ball screw 29 to rotate. The rotation of the ball screw 29 causes the ball nut 27 to move, and the ball nut 27 drives the positioning block 30 to move until the positioning block 30 moves to the variable resistor. 28 is at the preset resistance value; during the process of draining ascites, the hook 7 drives the movable plate 18 to move, and the movable plate 18 pushes the slider of the variable resistor 28 to move through the pushing block 21 until the variable pushing block 21 contacts the positioning block 30. At this time, the amount of ascites in the drainage bag is the preset amount of draining ascites, and when the pushing block 21 contacts the positioning block 30, the alarm 6 sounds an alarm, the electromagnet 13 is in a powered state, and the clamping block 8 is used to clamp the drainage tube to avoid excessive drainage of ascites; during the movement of the slider of the variable resistor 28, the resistance of the variable resistor changes, the excitation voltage on the circuit where the variable resistor is located changes, and a changing analog signal is output; the signal is amplified by the amplifying circuit and output to the analog-to-digital converter, thereby converting it into a digital signal that is easy to process and output to the controller; the controller outputs this result to the display, and the display screen 3 can display the weight of the ascites.
