Description

Technical Field

[0001] This invention relates to the field of neonatal warming and weighing technology, specifically a portable warming and weighing scale system for newborns. Background Technology

[0002] Newborns, especially premature and critically ill newborns, require continuous and accurate weight monitoring during hospitalization. Weight changes are important indicators for assessing their fluid balance, nutritional intake, and growth and development, and are also an important basis for clinicians to adjust treatment plans and medication dosages. In the neonatal intensive care unit, weight measurement is a high-frequency and necessary daily operation.

[0003] In current technology, newborn weight is usually measured using a stand-alone infant scale. In practice, caregivers need to remove the newborn from the incubator or radiant warmer and transfer them to the scale for measurement. However, since ordinary scales are usually at room temperature and the body needs to be exposed for a short time during the weighing process, newborns are prone to a drop in body temperature, especially for low-weight infants or those with weak thermoregulation, which poses a significant clinical risk. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a portable, insulated weight scale system for newborns, which has the advantages of enabling safe, convenient, and accurate weight measurement while ensuring the newborn's body temperature remains stable.

[0005] (II) Technical Solution To achieve the aforementioned goal of safe, convenient, and accurate weight measurement while ensuring stable newborn body temperature, this invention provides the following technical solution: a portable insulated weight scale system for newborns, comprising: Mobile base; A support column is vertically mounted on the movable base; A weighing assembly is disposed at the upper end of the support column. The weighing assembly includes a mounting base and a weighing sensor fixedly disposed on the mounting base. A detachable grooved weighing pad is disposed above the weighing sensor. An insulation cover is installed on the outside of the weighing pad, and the insulation cover and the weighing pad together form an insulated weighing chamber; The heating system operates inside the insulated weighing chamber; A temperature sensor is installed inside the insulated weighing chamber; The control unit is electrically connected to the weighing sensor, heating system, and temperature sensor.

[0006] Furthermore, in this invention, the bottom of the movable base is equipped with casters.

[0007] Furthermore, in this invention, the supporting column is a height-adjustable structure.

[0008] In this invention, the heating system is further described as a far-infrared heater or a warm air circulation heating component.

[0009] In this invention, the control unit is further configured to control the heating system to operate based on the temperature signal collected by the temperature sensor, so as to maintain the temperature inside the insulated weighing chamber within a preset range.

[0010] Furthermore, in this invention, the control unit includes a wireless communication module for uploading measurement data to the hospital's electronic information system.

[0011] Furthermore, in this invention, the control unit includes an identity recognition interface for recognizing newborn identity information and binding it to measurement data.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides a portable insulated weighing scale system for newborns, which has the following beneficial effects: 1. This portable incubator and weighing scale system for newborns, by setting up a movable base and supporting columns, allows the weighing components to be moved as a whole to the incubator or bedside for operation, reducing the transfer distance of newborns, lowering the risk of catheter dislodgement or falling during transportation, and improving the safety of nursing care.

[0013] 2. This portable insulated weighing scale system for newborns, by setting an insulated cover on the outside of the weighing pad and enclosing it with the weighing pad to form an insulated weighing chamber, keeps the newborn in a relatively closed and insulated environment during the weighing process, effectively reducing body heat loss.

[0014] 3. This portable insulated weighing scale system for newborns, by installing a heating system and temperature sensor in the insulated weighing chamber and electrically connecting them to the control unit, can realize real-time monitoring and adjustment of the temperature inside the chamber, so as to maintain the insulated environment within a preset range and ensure the temperature of the newborn during weighing.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example: Please see Figure 1 This invention proposes a portable, insulated weight scale system for newborns, which is suitable for scenarios such as neonatal wards and NICUs that require high-frequency weight monitoring and have high requirements for heat preservation. The system integrates mobility, heat preservation, weighing and data management into one, and can complete weight collection without exposing newborns to room temperature for a long time, and automatically archive the data to the hospital's information system.

[0019] like Figure 1 As shown, the weighing scale system includes a movable base 1, a support column 3, a weighing component, an insulation cover 5, a heating system 7, a temperature sensor 8, and a control unit.

[0020] The mobile base 1 serves as the load-bearing structure of the entire machine, supporting the upper support column 3 and the weighing components, and providing a basis for the movement and alignment of the equipment. The bottom of the mobile base 1 is evenly equipped with casters 2, which are preferably silent medical casters to reduce noise interference when pushing the equipment in the ward environment. Furthermore, the casters 2 have a braking structure. After the nurse pushes the equipment to the incubator or radiant table, the casters 2 can be locked by foot pedal or manual lever to prevent the equipment from shifting during the weighing process, which could lead to safety risks or weighing errors. The mobile base 1 can be made of metal frame or high-strength engineering plastic. Its upper surface can be provided with a connecting seat for fixing the support column 3. The connecting seat can be fixed by bolt connection, snap connection or welding, etc., so as to ensure the vertical stability of the support column 3.

[0021] The support column 3 is vertically mounted on the movable base 1 to raise the weighing component to a suitable height for docking with incubators, radiant beds, or nursing tables of different heights. Preferably, the support column 3 is a height-adjustable structure, specifically a telescopic column structure, such as an outer column and an inner column sleeved together to form a telescopic mechanism, and a knob locking mechanism to achieve height positioning, allowing nursing staff to quickly adjust the height and reliably fix it. The outer wall of the support column 3 can also be provided with scale markings to indicate the height adjustment range and improve usage efficiency.

[0022] The weighing component is set at the upper end of the support column 3. The weighing component specifically includes a mounting base and a weighing sensor 9 fixedly mounted on the mounting base. The mounting base is a load-bearing platform used to securely install the weighing sensor 9 and connect it to the support column 3. The mounting base can be made of metal plate or reinforcing rib structure to improve rigidity and reduce deformation caused by external force disturbance. The load cell 9 can be a strain gauge load cell 9, a single-point load cell 9, or a multi-point load cell 9, or a combination thereof.

[0023] In this embodiment, a detachable grooved weighing pad 6 is provided above the weighing sensor 9. The weighing pad 6 is used to directly support the newborn. The groove is preferably a "bird's nest" shaped arc-shaped depression, which puts the newborn in a relatively stable and more enveloping posture, reduces the risk of rolling displacement, and improves comfort. The weighing pad 6 can be made of medical-grade silicone.

[0024] In this embodiment, the weighing pad 6 is detachably connected to the weighing component. Specifically, it can be connected by a snap-on, plug-in, or magnetic method. This allows the weighing pad 6 to be disassembled for cleaning, disinfection, or replacement between different children, thereby reducing the risk of cross-infection.

[0025] like Figure 1 As shown, the heat insulation cover 5 is placed on the outside of the weighing pad 6, and the heat insulation cover 5 and the weighing pad 6 together form a heat insulation weighing chamber. The heat insulation cover 5 can be a semi-enclosed structure or a fully enclosed structure. The semi-enclosed structure can reserve an opening for nursing operations while ensuring heat preservation, while the fully enclosed structure can form a more stable thermal environment (with a movable openable mask as a matching accessory). The heat insulation cover 5 is preferably made of transparent or semi-transparent materials (such as medical transparent PC, PMMA, etc.) so that caregivers can observe the newborn's condition at any time. In order to reduce heat leakage, the contact point between the heat insulation cover 5 and the weighing pad 6 is preferably equipped with a flexible sealing ring to make the heat insulation weighing chamber relatively sealed, thereby improving heating efficiency and reducing temperature fluctuations.

[0026] In this embodiment, the heating system 7 operates inside the insulated weighing chamber to maintain a stable temperature inside the chamber during the weighing process; specifically, the heating system 7 can be a far-infrared heater or a warm air circulation heating component. When a far-infrared heater is used, the heating system 7 is preferably installed on the top or inside the side wall of the heat preservation cover 5 to heat the inside of the heat preservation weighing chamber by radiation, so as to avoid direct hot air blowing and causing discomfort to the newborn. When a warm air circulation heating component is used, the heating system 7 may include a miniature heater and a blower. The hot air is gently circulated within the chamber through the air guide structure, thereby obtaining a more uniform temperature field distribution.

[0027] Temperature sensor 8 is installed inside the insulated weighing chamber to collect the real-time temperature inside the chamber. The temperature sensor 8 is preferably placed close to the height area where the newborn is located to avoid being too close to the heating source, which would cause the reading to be too high. The temperature sensor 8 can be in the form of a thermistor, a digital temperature probe, etc., and is connected to the control unit through wires.

[0028] The control unit is electrically connected to the weighing sensor 9, the heating system 7 and the temperature sensor 8. The control unit can be integrated in the upper middle part of the support column 3 or the side of the mounting base so that nursing staff can operate and read information. The control unit includes a main control circuit board, a touch control screen 4, a power supply module and necessary interface circuits. The control unit is used to control the operation of the heating system 7 based on the temperature signal collected by the temperature sensor 8, so as to maintain the temperature in the insulated weighing chamber within a preset range. Specifically, the nursing staff can set the target temperature range on the touch control screen 4, such as setting the upper limit temperature and the lower limit temperature. The control unit reads the feedback from the temperature sensor 8 in real time. When the temperature is lower than the lower limit, it drives the heating system 7 to start heating. When the temperature reaches the target range or approaches the upper limit, it reduces the heating power or stops heating, thereby forming a closed-loop temperature control. To enhance safety, the control unit can also be set with an over-temperature protection threshold. When the temperature abnormally exceeds the safety threshold, the heating system 7 will be immediately shut off and an alarm will be triggered.

[0029] In terms of weighing, the control unit receives the weight signal output by the weighing sensor 9 and can perform calibration, tare, and stable display processing. To address weight fluctuations caused by the newborn's slight movements, the control unit can filter the weight signal and output a stable weight value after meeting the stability criteria, reducing the workload of repeated readings for caregivers.

[0030] The control unit includes a wireless communication module for uploading measurement data to the hospital's electronic information system. The wireless communication module can be a Wi-Fi or Bluetooth module. The control unit sends weight data, measurement time, and other information to the nursing workstation, mobile nursing terminal, or hospital HIS / EMR system according to a preset protocol, enabling automatic data recording. In this embodiment, the control unit includes an identification interface for identifying the newborn's identity information and binding it to the measurement data. The identification interface can be a QR code scanning interface or an RFID reading interface. Before weighing, caregivers can scan the newborn's wristband QR code or read the RFID tag. The control unit obtains the child's unique identification based on this, associates the weighing data with this identification, and then uploads it to the hospital's electronic information system, thereby improving data traceability and reducing the risk of confusion.

[0031] During use, nursing staff push the equipment to the incubator or radiant warmer, position and lock it using the casters 2; then adjust the height of the support column 3 so that the weighing pad 6 is at a convenient height for placing the newborn; next, open the opening structure of the heat insulation cover 5 and place the newborn in the recessed weighing pad 6; then close the heat insulation cover 5 to form a heat-insulated weighing chamber, and the control unit controls the heating system 7 to maintain the temperature inside the chamber based on the signal from the temperature sensor 8; at the same time, the control unit collects data from the weighing sensor 9 and outputs the weight result; if necessary, identity verification and binding are performed first, and then the weight data is uploaded to the hospital's electronic information system by the wireless communication module to complete the recording and archiving; after use, the weighing pad 6 can be removed for cleaning and disinfection to meet the infection control requirements of the ward.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
