Abstract
Description
Technical Field
[0001] This utility model relates to the field of drainage bags, specifically a drainage bag that can monitor flow rate. Background Technology
[0002] A drainage bag is a medical device used after surgery to drain blood, fluid, or other fluid from inside the body or deep within a surgical site. The end of the drainage tube is connected to a disposable transparent bag specifically for holding the drainage fluid. The bag is made of medical-grade polymer material and is packaged in a low-pressure PE bag.
[0003] Currently, existing technology has the following shortcomings: the main unit consists of only one tube, with one end connected to the patient and the other to a bag, making it impossible to directly observe whether the drainage fluid is flowing smoothly or at what rate. For example, if a patient needs drainage of ascites, and the doctor's order requires clamping the drainage tube when the drainage volume reaches 500ml, but there is currently a lack of relevant monitoring and an early warning system to remind the nurse that the drainage volume has reached the required level, the consequence is that the drainage tube is not clamped in time, causing adverse effects on the patient.
[0004] Therefore, a flow monitoring bag is proposed to address the above problems. Utility Model Content

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0023] Please see Figures 1-5 As shown, a flow monitoring bag includes a main body 1. A monitoring installation device 2 is provided on the top side of the main body 1. The monitoring installation device 2 includes a flow monitoring component 3 and an installation and disassembly component 4. The flow monitoring component 3 includes a Mofe's dropper 24 provided on the top side of the main body 1. A slot 25 is provided on one side of the Mofe's dropper 24, and a locking block 26 is movably installed through the slot 25. A flow monitoring sensor 27 is fixedly installed on the other side of the locking block 26. An alarm 28 is electrically connected to one side of the flow monitoring sensor 27. A display panel 29 is fixedly installed on the outer surface of the alarm 28. A fixing ring 31 is fixedly installed on one side of the flow monitoring sensor 27.
[0024] During operation, the slot 25 is opened on one side of the Mofly dropper 24, so that the locking block 26 and the slot 25 of the Mofly dropper 24 are in transitional engagement. This connects the flow monitoring sensor 27 installed on one side of the locking block 26 to the Mofly dropper 24. The flow monitoring sensor 27 continuously monitors the flow inside the Mofly dropper 24 and feeds the monitored flow back to the display panel 29 for display. Personnel can set a threshold for the flow. When the flow reaches the preset threshold, the alarm 28 will sound an alarm.
[0025] Furthermore, the flow monitoring device 3 also includes a drainage tube 21, one end of which is fixedly installed with a puncture device 23, and the main body 1 can be installed and removed on one side of the puncture device 23. A water stop regulator 22 is fixedly installed on one side of the drainage tube 21, and a Mofe's drip tube 24 is fixedly installed on one side of the drainage tube 21.
[0026] During operation, drainage tube 21 is used for drainage. With the installation of water stop regulator 22, it is easy to control the flow rate inside drainage tube 21, so that the liquid is collected in the inner cavity of the main body 1 through puncture device 23.
[0027] Furthermore, the installation and disassembly component 4 includes a fixing ring 31, two first fixing arms 32 are fixedly installed on one side of the fixing ring 31, and a first movable arm 33 is movably installed on one side of each of the two first fixing arms 32. The outer surfaces of the first fixing arms 32 and the first movable arms 33 are threaded, and a first threaded sleeve 35 is threadedly connected to them through the threaded wires.
[0028] During operation, the first fixed arm 32 and the first movable arm 33 are connected to each other. When the operator rotates the first threaded sleeve 35 clockwise, the first threaded sleeve 35 moves to one side. The threads on the first fixed arm 32 and the first movable arm 33 are used to adjust the gap between the first fixed arm 32 and the first movable arm 33 during the movement of the first threaded sleeve 35.
[0029] Furthermore, the installation and disassembly component 4 also includes a first ball head 36, which is movably installed between the first fixed arm 32 and the first movable arm 33, and a second fixed arm 34 is fixedly installed on one side of the first ball head 36.
[0030] During operation, when the operator rotates the first threaded sleeve 35 counterclockwise, the gap between the first fixed arm 32 and the first movable arm 33 widens. At this time, the operator can adjust the angle of the second fixed arm 34. During the adjustment process, the first ball head 36 rotates within the gap between the first fixed arm 32 and the first movable arm 33. When the adjustment is completed, the operator rotates the first threaded sleeve 35 clockwise to reduce the gap between the first fixed arm 32 and the first movable arm 33, thereby locking and limiting the first ball head 36 so that it cannot rotate.
[0031] Furthermore, a second movable arm 37 is movably installed on one side of the second fixed arm 34. The outer surfaces of the second fixed arm 34 and the second movable arm 37 are provided with threads, and a second threaded sleeve 38 is threadedly connected through the threads. A second ball head 39 is movably installed between the second fixed arm 34 and the second movable arm 37.
[0032] When the angle adjustment of the second fixed arm 34 is still limited during operation, the second threaded sleeve 38 is rotated counterclockwise to widen the gap between the second movable arm 37 and the second fixed arm 34, so that the second ball head 39 can move freely and thus make corresponding adjustments.
[0033] Furthermore, a first clamping plate 41 is fixedly installed on one side of the second ball head 39, and a second clamping plate 42 is hinged to the other side of the first clamping plate 41. A spring is provided between the first clamping plate 41 and the second clamping plate 42, and a clearance fit is formed between the first clamping plate 41 and the second clamping plate 42 for the drainage tube 21.
[0034] During operation, personnel place the drainage tube 21 between the first clamp 41 and the second clamp 42, and the unique elasticity of the spring causes the first clamp 41 and the second clamp 42 to contract, thereby limiting and fixing the drainage tube 21.
[0035] Working principle: In embodiment one, a slot 25 is provided on one side of the Mofee dropper 24, through which a block 26 is movably installed. A flow monitoring sensor 27 is fixed on the other side of the block 26, which connects the flow monitoring sensor 27 to the Mofee dropper 24. The flow monitoring sensor 27 continuously monitors the flow inside the Mofee dropper 24 and feeds back the monitored flow data to the display panel 29 for display. At the same time, a threshold can be set for the flow. When the flow reaches the preset threshold, the alarm 28 will sound an alarm.
[0036] In the second embodiment, the drainage tube 21 is placed between the first clamping plate 41 and the second clamping plate 42. The elasticity of the spring is used to cause the first clamping plate 41 and the second clamping plate 42 to contract, thereby limiting and fixing the drainage tube 21.
[0037] First-stage adjustment: Two first fixed arms 32 are installed on one side of the fixed ring 31. Each first fixed arm 32 is movably connected to a first movable arm 33. Their outer surfaces are provided with threads, and they are connected by threads through a first threaded sleeve 35. When the first threaded sleeve 35 is rotated clockwise, it will move to one side, using the threads to reduce the gap between the first fixed arm 32 and the first movable arm 33; when rotated counterclockwise, the gap will widen.
[0038] Angle adjustment: The first ball head 36 is movably installed between the first fixed arm 32 and the first movable arm 33, and the second fixed arm 34 is fixed on one side. When the gap between the first fixed arm 32 and the first movable arm 33 widens, the angle of the second fixed arm 34 can be adjusted. At this time, the first ball head 36 will rotate in the gap. After the adjustment is completed, the first threaded sleeve 35 is rotated clockwise to reduce the gap and lock the first ball head 36 in the limit position so that it cannot rotate.
[0039] Second-stage adjustment: The second fixed arm 34 is movably connected to the second movable arm 37 on one side. Their outer surfaces are also threaded and are connected by a second threaded sleeve 38. A second ball head 39 is movably installed between them. When the second threaded sleeve 38 is rotated counterclockwise, the gap between the second movable arm 37 and the second fixed arm 34 will widen, and the second ball head 39 can move freely, thereby allowing for further adjustment.
[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
