Description

Technical Field

[0001] The invention relates to the technical field of stretcher scales, in particular to a portable flexible stretcher scale. Background Art

[0002] In the field of medical emergency, accurate information on patient weight is crucial for rational medication and precise treatment. However, there are many problems in the current actual situation.

[0003] At present, the determination of patient weight at the emergency scene mainly relies on the medical staff's rough estimation. This method is limited by the medical staff's experience, the tense atmosphere at the scene, and the patient's physical condition (such as clothing, possible body position restrictions, etc.), resulting in large errors in weight estimation. For example, in an emergency, medical staff may only judge the patient's weight by sight and simple touch, which may be significantly different from the actual weight.

[0004] Inaccurate weight estimation directly affects the accuracy of medication. The calculation of drug dosage is often based on the patient's weight. If the weight data is wrong, it may result in insufficient medication and failure to achieve the therapeutic effect, or excessive medication causing adverse reactions, and even endangering the patient's life in severe cases. For example, the dosage range of some emergency drugs is narrow, and deviations in weight estimation may cause the dosage to deviate from the safe and effective range.

[0005] Existing weighing products have very low applicability in outdoor first aid scenarios. On the one hand, most of the common weighing equipment on the market are bulky and fixed in structure, making them difficult to use with stretchers. Stretchers need to be moved frequently during first aid transportation, and existing weighing products cannot be easily integrated into this process. On the other hand, these products do not fully consider the special needs of first aid scenarios, such as portability and rapid deployment. In emergency rescue, time is life, and weighing equipment that is inconvenient to carry will increase the burden on first aid personnel and delay treatment. For example, traditional large electronic scales cannot be quickly installed and used in complex first aid environments such as the wild and confined spaces, and cannot meet the requirements of first aid work for efficiency and flexibility.

[0006] In summary, the existing weight measurement methods and weighing products have obvious shortcomings in emergency rescue scenarios. The development of a portable flexible stretcher scale specifically for outpatient emergency rescue, perfectly adapted to the stretcher and capable of quickly and accurately measuring the patient's weight has great practical significance and urgent market demand. Summary of the invention

[0007] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a portable flexible stretcher scale, which solves the problems raised in the above background technology.

[0008] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions: A portable flexible stretcher scale, comprising a structural body, wherein the structural body comprises a main body weighing module and a display module; The weighing module is composed of rivets, a cover plate, an upper cover, a sensor, a foot cover, a main control module and a lower cover; The sensor and the foot cover are respectively installed between the upper cover and the lower cover; The main control module is fixed to the upper cover, and the upper cover, sensor, foot cover, main control module and lower cover are assembled into a whole, then assembled into the inside of the flexible connecting cloth and fixed with rivets and cover plates; Connect the above assembled main weighing module and display module with cables to transmit measurement data.

[0009] Furthermore, the sensor is a high-precision weighing sensor, whose model is FS018 weighing sensor. The sensor can accurately sense the weight change of the object on the stretcher and transmit the analog signal to the main control module. Under the 200kg range, the accuracy is ±100g.

[0010] Furthermore, the main control module is equipped with a high-performance microprocessor, which is a 32-bit microprocessor with a Cortex-M4 core. It has powerful data processing capabilities, can quickly calculate and convert data collected by the sensor, ensure the accuracy and timeliness of the data, and stably transmit the processed data to the display module.

[0011] Furthermore, the display module is a liquid crystal display screen with a screen size of 1.5 inches and a resolution of 320×240, which can clearly and intuitively display the measured weight data and related information, such as unit and measurement time.

[0012] Furthermore, the flexible connecting cloth is made of high-strength nylon canvas which is high-strength, wear-resistant and has a certain flexibility, and its thickness is 2.5mm. This material has the characteristics of waterproof, moisture-proof and corrosion-resistant, ensuring the stability and portability of the stretcher scale when used in various harsh environments, and can effectively compensate for weighing errors during use.

[0013] Furthermore, the upper cover and the lower cover are made of lightweight aluminum alloy, which not only ensures that the structural strength is sufficient to bear the weight of the stretcher and the patient, but also reduces the overall weight, making it convenient to carry and operate.

[0014] Furthermore, the main weighing module is also provided with a carrying handle for medical staff to grasp, and the carrying handle is connected to the main weighing module by bonding, which ensures a firm and reliable connection and facilitates carrying and transporting of the stretcher scale.

[0015] A method for using a portable flexible stretcher scale comprises the following steps: S1: Preparation: Check whether all parts of the portable flexible stretcher scale are intact, including the main weighing module, display module, cable and flexible connecting cloth; S2: Unfold and connect: Unfold the stretcher scale steadily to both sides, just like unfolding a carpet, until the stretcher scale is fully unfolded and laid flat on the ground. During the unfolding process, the movement should be gentle to avoid tearing the connecting cloth or damaging the internal components due to excessive force; Connect the main weighing module and the display module through a cable, and ensure that the connecting plug is tightly inserted into the corresponding interface without looseness. When connecting, pay attention to the correct matching of the direction of the plug and the interface to avoid damage to the interface caused by forced insertion. After the connection is completed, you can gently pull the cable to check whether the connection is firm. If the connection is found to be loose, reconnect it to ensure the stability of data transmission; S3: Weighing operation: The medical staff will steadily lift the stretcher with the patient onto the unfolded stretcher scale, ensuring that the four supporting points of the stretcher are evenly placed on the sensor positions corresponding to the main weighing module, and avoid the stretcher from tilting or partially hanging in the air, otherwise it may cause inaccurate measurement data. When placing the stretcher, try to keep the movement steady and slow to prevent damage to the sensor or affect the measurement accuracy due to excessive impact force; Wait for a few seconds to allow the sensor to fully sense the weight of the stretcher and the patient, and the main control module to complete data calculation and conversion. At this time, the display module will instantly display the measured patient weight data and related information; S4: Storage and Storing: After weighing, carefully lift the stretcher off the stretcher scale and put it back in place. Then, disconnect the cable connection between the main weighing module and the display module, and tidy up the cables to avoid entanglement or knots. Starting from one end of the stretcher scale, roll up the stretcher scale slowly and evenly along the length direction of the flexible connecting cloth. Try to keep it tight and neat during the rolling process to reduce the space occupied. At the end of the roll, use the quick storage hook and loop to fix the rolled stretcher scale to prevent it from spreading; Place the stored stretcher scale in a dry, ventilated place, avoid direct sunlight, high temperature, humidity or corrosive gas environment to prevent aging, damage or rust of parts, and extend the service life of the stretcher scale. At the same time, ensure that the storage location is safe to avoid being squeezed or collided with other objects.

[0016] Compared with the prior art, the present invention provides a portable flexible stretcher scale, which has the following beneficial effects: The present invention adopts a high-precision weighing sensor and a high-performance microprocessor to ensure high measurement accuracy and timely and accurate data processing, provide reliable weight data for medical staff, and ensure the accuracy of medication. The flexible connection cloth and reasonable design enable the stretcher scale to be quickly flattened and stored, and can be used in any direction, and can compensate for weighing errors and adapt to a variety of environments. The upper cover and lower cover made of lightweight aluminum alloy ensure strength while reducing weight, and the handle is convenient for carrying. The overall structural design greatly improves the practicability, maneuverability and portability of the equipment in emergency scenarios, which helps medical staff to efficiently carry out emergency work and improve the efficiency and quality of treatment.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] like Figure 1-3 As shown, a portable flexible stretcher scale proposed in one embodiment of the present invention includes a structural body, wherein the structural body includes a main body weighing module 1-1 and a display module 1-2; Overall structure The portable flexible stretcher scale is mainly composed of a structural body, which includes a main weighing module 1-1 and a display module 1-2. The main weighing module 1-1 is responsible for sensing and processing weight information, and the display module 1-2 is used to intuitively present the measurement results. The two work together to achieve accurate measurement and display of the weight of the patient on the stretcher.

[0021] Main weighing module 1-1 internal structure Rivet 1 and cover plate 2: Rivet 1 is used to fix cover plate 2 in a specific position, playing the role of connection and fastening. Cover plate 2 covers the assembled parts to protect the internal structure, preventing dust, debris, etc. from entering the interior to affect the normal operation of sensor 4 and other parts, and also enhancing the stability of the overall structure to a certain extent.

[0022] Upper cover 3 and lower cover 7: The upper cover 3 and lower cover 7 are made of lightweight aluminum alloy. Their shape design is compatible with the internal components, providing installation space and structural support for the sensor 4, foot cover 5 and main control module 6.

[0023] Function: The lightweight aluminum alloy material not only ensures sufficient structural strength to bear the weight of the stretcher and the patient, ensuring that it will not be deformed or damaged due to force during the weighing process, but also reduces the overall weight, making it easier for medical staff to carry and operate. At the emergency scene, the lighter weight helps improve the mobility of the equipment, allowing medical staff to deploy and use the stretcher scale more quickly.

[0024] Sensor 4: Sensor 4 uses a high-precision weighing sensor, model FS018 weighing sensor, which is installed between the upper cover 3 and the lower cover 7, and closely cooperates with the upper cover 3 and the lower cover 7 to accurately sense the weight change of the object on the stretcher. Its internal structure includes key components such as strain gauges, which generate analog signal output through the deformation caused by the weight of the object.

[0025] Function: Under the range of 200kg, the accuracy can reach ±100g, which can accurately measure the weight of the stretcher and the patient, convert the weight information into analog signals and transmit it to the main control module 6. In the emergency scenario, quickly and accurately obtaining the patient's weight is crucial for rational medication and precise treatment. The high precision of the sensor 4 ensures the reliability of the measurement data and provides an accurate basis for the decision-making of medical staff.

[0026] Foot cover 5: Foot cover 5 is installed at the bottom of lower cover 7. Its shape and size match those of lower cover 7, and anti-slip texture is provided on the bottom.

[0027] Function: The anti-skid pattern increases the friction with the ground, preventing the stretcher scale from sliding due to uneven force or smooth ground during weighing, thus ensuring the accuracy and stability of measurement. In different ground environments (such as smooth ground in hospitals, uneven ground outdoors, etc.), the foot cover 5 can keep the stretcher scale stable, avoiding measurement errors or accidents caused by sliding.

[0028] Main control module 6: Main control module 6 is fixed inside the upper cover 3, and has a built-in high-performance microprocessor, a 32-bit microprocessor with a Cortex-M4 core, which is connected to the sensor 4 and the display module 1-2 through a circuit and has data processing, calculation and transmission functions. Various electronic components, such as capacitors, resistors, chips, etc., are integrated on its circuit board to work together to process the sensor 4 signal.

[0029] Function: It can quickly calculate and convert the data collected by the sensor 4, such as converting analog signals into digital signals, and performing filtering, calibration and other processing to ensure the accuracy and timeliness of the data. The processed data is then stably transmitted to the display module 1-2 for display. The high performance of the main control module 6 ensures the rapid response and stable operation of the system, and can provide accurate weight data in a timely manner at the emergency site, thereby improving the work efficiency of medical staff.

[0030] The flexible connecting cloth 8 is made of high-strength, wear-resistant and flexible high-strength nylon canvas with a thickness of 2.5 mm. It is connected to the main weighing module 1-1 through a specific sewing or connection method, covering the bottom of the main weighing module 1-1, and has a flexible sheet structure as a whole.

[0031] Function: Its high strength and wear resistance ensure that the connecting cloth will not be easily damaged during the use of the stretcher scale (such as frequent placement and lifting of the stretcher, friction with the ground, etc.), thus extending the service life of the equipment. The flexibility allows the stretcher scale to be quickly flattened like a carpet, and it can be used without distinguishing the direction. It is convenient and fast, and meets the emergency needs of the first aid site. At the same time, it can effectively compensate for weighing errors during use and improve the accuracy of measurement. Its waterproof, moisture-proof and corrosion-resistant properties ensure the stability and portability of the stretcher scale when used in various harsh environments, ensuring the normal operation of the equipment.

[0032] The display module 1-2 is a liquid crystal display screen with a screen size of 1.5 inches and a resolution of 320×240. It is connected to the main control module 6 in the main weighing module 1-1 via a cable and is installed in a position convenient for medical staff to view.

[0033] Function: It can clearly and intuitively display the measured weight data and related information, such as unit, kg or lb, measurement time, etc. Medical staff can obtain the patient's weight information at a glance at the emergency scene without complicated operations or additional interpretation, and directly use it for subsequent medical decision-making, improving work efficiency and accuracy.

[0034] The carrying handle (marked in the figure but not mentioned in detail in the description) is arranged on the main weighing module 1-1 and is connected to the main weighing module 1-1 by bonding. The shape design conforms to the principles of ergonomics and is convenient for medical staff to grasp.

[0035] Function: It is convenient for medical staff to carry and transport the stretcher scale. During the transfer of the equipment (such as from the ambulance to the emergency site, moving between different departments of the hospital, etc.), it provides a convenient force application location, making the operation more convenient and labor-saving. At the same time, the adhesive connection ensures a firm and reliable connection, preventing the handle from falling off during transportation, and ensuring the safety of equipment and personnel.

[0036] like Figure 2 As shown, in some embodiments, the sensor 4 is a high-precision weighing sensor, whose model is FS018 weighing sensor. The sensor 4 can accurately sense the weight change of the object on the stretcher and transmit the analog signal to the main control module 6. Under the 200kg range, the accuracy is ±100g; for example, at the first aid site, whether the patient's weight increases slightly (such as adding clothes or carrying small medical equipment) or decreases (such as bleeding, etc.), the sensor 4 can keenly detect it and convert it into an electrical signal change, providing accurate weight information for medical staff so that the treatment plan can be adjusted in time.

[0037] like Figure 2 As shown, in some embodiments, the main control module 6 is equipped with a high-performance microprocessor, which is a 32-bit microprocessor with a Cortex-M4 core. It has powerful data processing capabilities and can quickly calculate and convert the data collected by the sensor 4 to ensure the accuracy and timeliness of the data, and stably transmit the processed data to the display module 1-2; if data errors or losses occur during the transmission process, the microprocessor can take retransmission or error correction measures to ensure that the display module 1-2 can normally display accurate weight data, so that medical staff can reliably obtain measurement results and provide strong support for medical work.

[0038] like Figure 2 As shown, in some embodiments, the display module 1-2 is a liquid crystal display screen with a screen size of 1.5 inches and a resolution of 320×240, which can clearly and intuitively display the measured weight data and related information, such as units and measurement time; the 1.5-inch LCD screen is relatively small, making the entire portable flexible stretcher scale easy to carry and operate, and can also be conveniently used in small emergency spaces (such as inside an ambulance, outdoor rescue sites, etc.) without taking up too much space. Whether in an indoor hospital environment or an outdoor emergency rescue scene, the display screen can work stably, providing medical staff with reliable weight data display, adapting to various complex use environments, and meeting the requirements of emergency work for equipment portability and practicality.

[0039] like Figure 2As shown, in some embodiments, the flexible connecting cloth 8 is made of high-strength, wear-resistant and flexible high-strength nylon canvas with a thickness of 2.5 mm. The material has the characteristics of being waterproof, moisture-proof and corrosion-resistant, ensuring the stability and portability of the stretcher scale when used in various harsh environments, and can effectively compensate for weighing errors during use; during the weighing process, due to the characteristics of the connecting cloth itself (such as flexibility, elasticity, etc.) and the interaction with other components, it may have a certain impact on the weighing result. The flexible connecting cloth 8 can effectively compensate for these weighing errors caused by its own factors through its special material and structural design. For example, when the stretcher is placed on the connecting cloth, the slight deformation of the connecting cloth may be adjusted by its own compensation mechanism, making the weight signal received by the sensor 4 more accurate, thereby improving the measurement accuracy of the entire stretcher scale, providing more reliable weight data for medical staff, and ensuring the accuracy of medical decisions.

[0040] like Figure 2 As shown, in some embodiments, the upper cover 3 and the lower cover 7 are made of lightweight aluminum alloy, which not only ensures that the structural strength is sufficient to bear the weight of the stretcher and the patient, but also reduces the overall weight, making it convenient to carry and operate; the lightweight aluminum alloy material is easy to process and shape, which is conducive to the manufacture of the upper cover 3 and the lower cover 7 and the assembly with other components. During the production process, a variety of processing techniques (such as die casting, stamping, etc.) can be used to achieve complex shape design to ensure precise matching with internal components. During equipment maintenance and repair, the aluminum alloy shell is also easy to disassemble and reinstall, which is convenient for technicians to inspect, replace or repair internal components.

[0041] like Figure 2 As shown, in some embodiments, the main weighing module 1-1 is also provided with a handle for medical staff to grasp, and the handle is connected to the main weighing module 1-1 by bonding, ensuring a firm and reliable connection, and facilitating carrying and transporting the stretcher scale; the presence of the handle greatly enhances the mobility and portability of the portable flexible stretcher scale. Medical staff can hold the handle with one or both hands and easily carry the stretcher scale to where it is needed, whether in narrow passages, stairwells or on uneven ground, and can easily move the equipment; A method for using a portable flexible stretcher scale comprises the following steps: S1: Preparation: Check whether all parts of the portable flexible stretcher scale are intact, including the main weighing module 1-1, the display module 1-2, the cable and the flexible connecting cloth 8; S2: Unfold and connect: Unfold the stretcher scale steadily to both sides, just like unfolding a carpet, until the stretcher scale is fully unfolded and laid flat on the ground. During the unfolding process, the movement should be gentle to avoid tearing the connecting cloth or damaging the internal components due to excessive force; Connect the main weighing module 1-1 and the display module 1-2 through a cable, and ensure that the connection plug is tightly inserted into the corresponding interface without looseness. When connecting, pay attention to the correct matching of the direction of the plug and the interface to avoid forced insertion and damage to the interface. After the connection is completed, gently pull the cable to check whether the connection is firm. If the connection is not tight, reconnect it to ensure the stability of data transmission; S3: Weighing operation: The medical staff lifts the stretcher with the patient on it steadily onto the unfolded stretcher scale, ensuring that the four supporting points of the stretcher are evenly placed on the positions of the sensors 4 corresponding to the main weighing module 1-1, and avoiding the stretcher from tilting or partially hanging in the air, otherwise the measurement data may be inaccurate. During the process of placing the stretcher, the movement should be kept as steady and slow as possible to prevent the sensor 4 from being damaged or affecting the measurement accuracy due to excessive impact force; Wait for a few seconds to allow the sensor 4 to fully sense the weight of the stretcher and the patient, and the main control module 6 to complete the data calculation and conversion. At this time, the display module 1-2 will instantly display the measured patient weight data and related information; S4: Storage and storage: After weighing is completed, carefully lift the stretcher off the stretcher scale and put it back to its original position. Then, disconnect the cable connection between the main weighing module 1-1 and the display module 1-2, and arrange the cables to avoid entanglement or knotting. Starting from one end of the stretcher scale, roll up the stretcher scale slowly and evenly along the length direction of the flexible connecting cloth 8, and try to keep it tight and neat during the rolling process to reduce the occupied space. At the end of the rolling, use the quick storage hook and loop to fix the rolled stretcher scale to prevent it from spreading; Place the stored stretcher scale in a dry, ventilated place, avoid direct sunlight, high temperature, humidity or corrosive gas environment to prevent aging, damage or rust of parts, and extend the service life of the stretcher scale. At the same time, ensure that the storage location is safe to avoid being squeezed or collided with other objects.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
