Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary devices, and in particular relates to a measuring device for assisting in the volume management of heart failure patients. Background Technology

[0002] Heart failure patients require strict daily recording of fluid intake and output. Urine output and drainage volume are considered outputs, while fluid intake and intravenous fluids are considered inputs. The key to their treatment lies in volume management, quickly assessing the current balance. Currently, volume management primarily relies on paper records, which cannot display the cumulative net balance in real time, hindering timely adjustments to the treatment plan. Both healthcare professionals and patients struggle to quickly grasp the current balance, as the records lack intuitiveness. Traditional mechanical counters only support unidirectional accumulation and cannot simultaneously compare intake and output data. Existing electronic monitoring devices, such as smart urine analyzers, can record automatically, but they are expensive, complex to operate, and cannot cover diverse scenarios such as pleural effusion drainage and dietary intake. Summary of the Invention

[0003] The purpose of this invention is to provide a metering device that assists in volume management for patients with heart failure. It has a simple structure, low manufacturing cost, and can intuitively and in real time display the cumulative net balance, facilitating quick decision-making by medical staff.

[0004] The technical solution adopted in this utility model is: A measuring device for assisting volume management in patients with heart failure consists of three concentric discs, one of which is a fixed disc with a volume scale, and the other two are rotatable movable discs. Each movable disc is equipped with a pointer. The intake and output volumes are measured by the pointers and the volume scale. The difference in distance between the two pointers directly represents the net balance.

[0005] The volume scale ranges from 0 to 1600 ml, with a scale line every 10 ml and a number marked every 100 ml.

[0006] The pointers are designed to be different colors and / or different sizes.

[0007] The fixing plate is located on the outermost ring and is fixed to the base.

[0008] One of the active panels is an output panel, which measures the output quantity, and the other is an input panel, which measures the input quantity.

[0009] The infeed dial is in the middle circle, and the outfeed dial is in the inner circle.

[0010] The output dial is in the middle circle, and the input dial is in the inner circle.

[0011] The beneficial effects of this utility model are: This invention consists of only three concentric discs, has a simple structure, low manufacturing cost, and is suitable for primary healthcare settings. It can help heart failure patients manage volume, intuitively display real-time net balance, assist medical staff in making quick decisions, and reduce the risk of volume overload for heart failure patients. Attached Figure Description

[0012] In order to clearly illustrate the technical solutions in the embodiments of this utility model and enable those skilled in the art to better understand this utility model, the accompanying drawings used in the description of the embodiments are described below.

[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the structure of this utility model; In the diagram, 1 is the fixed plate, 2 is the input plate, 3 is the output plate, 4 is the balance indicator area, 5 is pointer A, and 6 is pointer B. Detailed Implementation

[0014] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0015] from Figure 1 As can be seen, this utility model is a measuring device for assisting in volume management of heart failure patients. It consists of three concentric discs. The outer ring is a fixed disc 1 with volume scale, fixed to the base. The volume scale range is 0-1600ml, with a scale line every 10ml and a number marked every 100ml. The middle ring is an inlet disc 2 with a pointer A on it. Pointer A can rotate with the outlet disc to accumulate the output volume. The inner ring is an outlet disc 3 with a pointer B on it. Pointer B can rotate with the inlet disc to accumulate the intake volume. Between pointers A and B is a balance indicator area 4. The difference in distance between pointers A and B directly represents the net balance volume. Net balance volume = intake volume - output volume. Figure 1 This is the initial state.

[0016] The usage status of this utility model is from Figure 2As can be seen, the output volume of this invention is measured by rotating the inner output dial clockwise. For example, after a patient urinates 800ml, the pointer B on the output dial is rotated clockwise by 800ml. The input volume is measured by rotating the middle input dial clockwise. For example, after a patient drinks 400ml of water, the pointer A on the input dial is rotated clockwise by 400ml. Observe the distance between the two pointers: at this time, pointer B is in front of pointer A, and the net balance is -400ml. In this invention, "before and after" is based on the clockwise direction. If the patient subsequently has any output or input volume, the output or input dial is rotated in the same way as described above, and the net balance is indicated in real time by the distance between the two pointers.

[0017] This invention can be used in conjunction with paper record sheets. By comparing and correcting the disc record with the paper record sheet daily, the accuracy of patient intake and output records can be ensured, assisting medical staff in making quick decisions.

[0018] The outer ring of this invention is made of ABS plastic, and the middle / inner ring is made of transparent acrylic. The production cost is relatively high, but the reusability is strong. Alternatively, the outer ring can be made of white cardboard, the middle ring of blue coated paper, and the inner ring of yellow coated paper. The yellow / blue colors can make it easy for red-green colorblind people to distinguish them. The production cost is low, but the reusability is poor.

[0019] The present invention can also interchange the infeed plate 2 and the outfeed plate 3, that is, the outfeed plate is in the middle circle and the infeed plate is in the inner circle.

[0020] The pointers in this invention are designed to be different colors and sizes: for example, the size difference between pointer A (white) and pointer B (black) can increase visual distinguishability.

[0021] The embodiments described herein are merely elaborations on the implementation methods and are not intended to limit the concept and scope of this utility model. Any modifications and improvements made by those skilled in the art to the technical solutions of this utility model without departing from its design concept should fall within the protection scope of this utility model.
