Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic scale technology, and in particular to a medical measuring electronic scale. Background Technology
[0002] For critically ill patients, close monitoring of their fluid and solid intake and output over 24 hours is clinically necessary. In a healthy individual, daily intake and output maintain a dynamic balance. Insufficient intake or excessive water loss due to illness can lead to dehydration, while excessive intake or reduced output can cause edema. Therefore, accurately recording a patient's intake and output is crucial for monitoring changes in their condition and developing appropriate treatment plans.
[0003] Intake and output include solid and liquid intake and output. Output includes urine output, stool volume, drainage volume, and wound exudate. In clinical practice, liquid intake and output can be measured using standard measuring cups. However, for solid intake and output, due to various subjective and objective factors, the recording often contains errors. For example, subjective factors include nurses estimating the water content of solid foods like steamed buns and rice. However, the estimated data varies depending on the nurse's experience, leading to inaccurate recording. Furthermore, nearly 50% of nurses record weight when recording formed stools and non-liquid foods, but use liquid units in the 24-hour intake and output record. Objective factors include inaccurate measuring containers, such as inaccurate patient-purchased measuring containers; and inaccurate graduations on disposable hospital-provided containers, such as disposable closed chest drainage bottles, disposable urinals, disposable gastrointestinal decompression devices, disposable urine bags, and drainage bags, which have graduations that deviate from standard measurements and cannot be used as tools for measuring intake and output. For solid intake and output, such as food moisture content comparison lists and fecal moisture content conversion, the usage rate is low, the work is cumbersome, and the recording cannot be accurate, so the measurement tools still cannot meet the clinical needs.
[0004] A medical measuring device with patent number CN212779444U is a scale specifically designed to measure input and output volumes. However, it can only weigh objects with recorded data, making it a single-function device that cannot meet other daily weighing needs.
[0005] Therefore, it is necessary to propose a medical electronic scale that can meet both the weighing needs for inflows and outflows and the daily weighing needs, serving two purposes in one device. Utility Model Content
[0006] To address the aforementioned issues, this invention proposes a medical electronic scale that can meet both inbound and outbound weighing needs, as well as daily weighing requirements, thus serving a dual purpose.

[0013] Furthermore, the side wall of the insertion slot is provided with a first magnet, and one side of the second scale body is provided with a second magnet. The first magnet and the second magnet are aligned and magnetically attracted to each other.
[0014] Furthermore, the insertion slot is inclined.
[0015] Furthermore, multiple function buttons are provided on one side of the first scale body.
[0016] Furthermore, the first scale body is provided with a first data processing module, a first weighing module, and a first storage module, and the second scale body is provided with a second data processing module, a second weighing module, a display module, and a second storage module. The first data processing module is electrically connected to the first weighing module, the first storage module, and the second data processing module, respectively, and the second data processing module is electrically connected to the second weighing module, the display module, and the second storage module, respectively. The first data processing module is used to receive the data weighed by the first weighing module and send the data weighed by the first weighing module to the second data processing module.

The second data processing module is used to receive data sent from the first data processing module and data weighed by the second weighing module. When the first scale body and the second scale body are electrically connected, the second data processing module sends the data weighed by the first weighing module to the display module for display.

When the second scale body 2 is electrically connected to the first scale body 1, the other end of the second scale body 2 serves as the display screen 24 of the first scale body 1.
[0022] In this embodiment, a combination of a first weighing body 1 and a second weighing body 2 is used. The first weighing body 1 is used for weighing the input and output quantities. The second weighing body 2 can be stored in the storage part 11 of the first weighing body 1. When placed, the second weighing body 2 and the first weighing body 1 are electrically connected. When the second weighing body 2 and the first weighing body 1 are electrically connected, the first weighing body 1 weighs the input and output quantities. The other end of the second weighing body 2 acts as the display screen 24 of the first weighing body 1 to display the input and output quantity data weighed by the first weighing body 1. When the second weighing body 2 is removed so that the second weighing body 2 is disconnected from the first weighing body 1, the second weighing body 2 can be used as an electronic hook scale alone to weigh other objects, which is convenient for daily weighing. After the second weighing body 2 is removed, the data weighed by the object placed on the first weighing body 1 cannot be displayed. The display screen 24 will only display the data weighed by the first weighing body 1 after the second weighing body 2 is put back into the storage part 11 and electrically connected to the first weighing body 1. In summary, this medical weighing scale can meet both the weighing needs for incoming and outgoing quantities and daily weighing needs, serving a dual purpose.
[0023] In this embodiment, the storage part 11 includes an insertion slot 111, and one end of the second scale body 2 is housed in the insertion slot 111. When storing the second scale body 2, the second scale body 2 is directly inserted into the insertion slot 111. When the second scale body 2 is inserted to the bottom of the insertion slot 111, the second scale body 2 and the first scale body 1 will form an electrical connection.
[0024] In this embodiment, the storage unit 11 includes a first connection port 112, which is located on the bottom wall of the insertion slot 111. One end of the second scale body 2 is provided with a second connection port 21. The first connection port 112 and the second connection port 21 are aligned and form a contact electrical connection. When the second scale body 2 is inserted into the bottom of the insertion slot 111, the first connection port 112 and the second connection port 21 are connected, so that the first connection port 112 and the second connection port 21 form a contact electrical connection. At this time, the weighing function of the second scale body 2 itself is suspended, and the display screen 24 will display the data of the first scale body 1.
[0025] In this embodiment, the first connection port 112 is provided with a plurality of conductive pins 1121 arranged in sequence, and the second connection port 21 is provided with a plurality of conductive contacts 211 arranged in sequence.

[0027] In this embodiment, a first magnet 1112 is provided on the side wall of the insertion slot 111, and a second magnet 23 is provided on one side of the second scale body 2. The first magnet 1112 and the second magnet 23 are aligned and magnetically attracted to each other. When the second scale body 2 is inserted into the end of the insertion slot 111, the first magnet 1112 and the second magnet 23 will magnetically attract to each other to secure the second scale body 2 in the insertion slot 111, and at the same time facilitate the removal of the second scale body 2.
[0028] In this embodiment, the insertion slot 111 is inclined, so that the second scale body 2 is tilted when placed in the insertion slot 111, which makes it easier for the user to view the display screen 24.
[0029] In this embodiment, a plurality of function buttons 12 are provided on one side of the first weighing body 1. The function buttons 12 have corresponding food text and labels. When the first weighing body 1 weighs food, the function buttons 12 are used to input the corresponding food label. After weighing, the weight and total water content will be displayed on the display screen 24. For example, if the food text and label on the first function button 12 are "meat" and "1", when weighing meat, the first function button 12 needs to be pressed, and then the function button 12 labeled "OK" is pressed. At this time, the first weighing body 1 will weigh the food and display the weight and total water content of the food on the display screen 24.
[0030] In this embodiment, the first weighing body 1 is provided with a first data processing module 101, a first weighing module 102, a first storage module 103, a broadcasting module 104, and a first power module 105. The second weighing body 2 is provided with a second data processing module 201, a second weighing module 202, a display module 203, a second storage module 204, a second power module 205, and a charging module 206.

The second data processing module 201 is electrically connected to the second weighing module 202, the display module 203, the second storage module 204, the second power module 205, and the charging module 206. The first data processing module 101 is used to receive the data weighed by the first weighing module 102 and send the data weighed by the first weighing module 102 to the second data processing module 201. It can also call the data in the first storage module 103. The first weighing module 102 is used to weigh the food. The first storage module 103 is used to store the water content data of each 100g of the pre-recorded food type, and also to store the food weight data weighed by the first weighing module 102 for a preset time. The broadcast module 104 is a speaker used to broadcast the weighed food data. When the user presses the corresponding broadcast function button 12, the broadcast module 104 starts to broadcast. The first power module 105 is used to convert mains power into DC power and supply it to the first data processing module 101. The first data processing module 101 then supplies the power to the first weighing module 102, the first storage module 103, the broadcasting module 104, the display module 203, the second storage module 204, and the charging module 206 for use. The second data processing module 201 is used to receive data sent from the first data processing module 101 and data weighed by the second weighing module 202. When the first weighing body 1 and the second weighing body 2 are electrically connected, the second data processing module 201 sends the data weighed by the first weighing module 102 to the display module 203 for display. When the first weighing body 1 and the second weighing body 2 are electrically disconnected, the second data processing module 201 sends the data weighed by the second weighing module 202 to the display module 203 for display. The second weighing module 202 is used to weigh the food; The display module 203 is electrically connected to the display screen 24 and is used to send corresponding display commands to the display screen 24. The second storage module 204 is used to store the food weight data weighed by the second weighing module 202 for a preset time. The second power module 205 is a lithium battery, used to supply power to the second weighing module 202, the display module 203, and the second storage module 204; The charging module 206 is used to charge the second power module 205 using the power from the first power module 105. In this embodiment, the first weighing body 1 is provided with a weighing platform 13, which is electrically connected to the first weighing module 102. When food is placed on the weighing platform 13 for weighing, the first weighing module 102 obtains the weighing data of the weighing platform 13 and then sends it back to the first data processing module 101. The first data processing module 101 then retrieves the corresponding water content per 100g of food from the first storage module 103 according to the pressed function button 12, and then calculates the total water content of the weighed food based on the weighed weight. The total water content and weight are then sent to the second data processing module 201. The second data processing module 201 then directly sends the total water content and weight to the display module 203. The display module 203 then sends the corresponding value display command to the display screen 24. The display screen 24 displays the total water content and weight. For example, if the function button 12 is pressed for rice, the display screen 24 will display the value of "weight 200g, water content 140g". When the second weighing body 2 is removed from the first weighing body 1, the second weighing body 2 can use the hook 22 to weigh external objects. At this time, the second weighing body 2 is an electronic hook scale. When weighing, the object can be hung on the hook 22 for weighing, and the display screen 24 displays the weighing value.
[0031] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
