Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, specifically to an emergency transport mattress device with active temperature control and adaptive pressure adjustment. Background Technology
[0002] During pre-hospital emergency care and in-hospital transport, patients often experience increased risk of secondary injury or complications due to hypothermia and concentrated local pressure. Existing emergency transport mattresses are mostly passive filled mattresses or simple air mattresses, and generally have the following shortcomings: 1. It cannot adaptively adjust the support pressure and distribution according to the patient's body shape and weight. If it is too soft, it will easily cause shaking and wobbling. If it is too hard, it will increase the risk of pressure sores. 2. It lacks active temperature maintenance function and is difficult to deal with hypothermia caused by shock, trauma, etc. 3. Its function is limited and it is only a physical support tool. It cannot collect key physiological interface information (such as pressure distribution and body temperature changes).
[0003] With the development of smart healthcare, especially the advancement of online and offline integrated intelligent diagnosis and treatment ecosystems and health big data platforms, there is a clear demand for continuous and objective monitoring of patients' physiological status throughout the entire emergency care process. The inadequacy of existing equipment has created an "information gap" in the process from transport to hospital admission, resulting in a lack of crucial on-site physiological parameters for the backend AI-assisted analysis system, thus hindering the forward-looking assessment of overall treatment efficiency and quality.
[0004] Therefore, there is an urgent need for an intelligent emergency transport mattress that integrates adaptive pressure regulation, active temperature control, and status information collection to ensure patient transport safety and provide reliable underlying data support for modern closed-loop emergency information systems. Summary of the Invention
[0005] The purpose of this invention is to provide an emergency transport mattress device with active temperature control and adaptive pressure adjustment to address the shortcomings mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an emergency transport mattress device with active temperature control and adaptive pressure adjustment, comprising: a top plate for supporting the patient, and: A base plate, which is parallel to and opposite to the top plate; A pressure adaptive adjustment mechanism, disposed between the top plate and the bottom plate, includes: A pressure-sensing component that deforms or displaces in response to a vertical load borne by the top plate; A transmission energy dissipation component, which is linked with the pressure sensing component, is used to convert vertical displacement into horizontal mechanical motion and dissipate it. The pressure sensing component includes a sealed pressure-bearing cavity, which is connected to a support airbag disposed on the top plate via a fluid pipeline. A physiological parameter monitoring mechanism is integrated into the top plate.
[0007] Preferably, the pressure-bearing cavity is formed by a rectangular sleeve and sealing sliding components at both ends; the sealing sliding components include a first rectangular block and a second rectangular block, one end of which is fixedly connected to the top plate and the bottom plate respectively, and the other ends of the first rectangular block and the second rectangular block are slidably and sealingly inserted into the two ends of the rectangular sleeve.
[0008] Preferably, a support plate is fixedly provided at the top of the top plate, and a groove is provided in the middle of the support plate. The support airbag is disposed in the groove. One end of the fluid pipeline is disposed in the middle of the rectangular sleeve, and the other end is provided with a one-way valve that allows the fluid to flow unidirectionally from the pressure-bearing cavity to the support airbag, and is connected to the bottom end of the support airbag.
[0009] Preferably, the transmission energy-dissipating component includes: A support frame is fixed to the outside of the rectangular sleeve, and a sliding groove is provided inside the support frame; A sliding element, which is slidably disposed in the sliding groove; A fixed rod is provided that passes through the sliding member; Several pairs of connecting rods, one end of which is rotatably connected to the top plate or bottom plate, and the other end of which is rotatably connected to the fixed rod; An energy dissipation element is disposed within the sliding groove and connected to the sliding member.
[0010] Preferably, the support frame is cross-shaped and has sliding grooves extending in four directions; The sliding member is correspondingly arranged with the sliding groove and can slide along the four directions of the sliding groove; the energy dissipation element is a tension spring, one end of which is connected to the sliding member and the other end of which is connected to the support frame.
[0011] Each pair of links includes a first link and a second link arranged symmetrically; one end of the first link is rotatably connected to the top plate and the other end is rotatably connected to the fixed rod; one end of the second link is rotatably connected to the bottom plate and the other end is rotatably connected to the fixed rod.
[0012] Preferably, the physiological parameter monitoring mechanism includes a weight measurement component, a temperature measurement and control component, and a pressure measurement component; The top plate has several independent monitoring panels on the side facing the patient. Each monitoring panel is equipped with at least one temperature sensor and heating element of the temperature measurement and control component, as well as at least one pressure sensor of the pressure measurement component.
[0013] Preferably, the monitoring modules are set according to the anatomical position of the human body, including a head module corresponding to the head, a back module corresponding to the back, a waist module corresponding to the waist, two arm modules corresponding to the left and right upper limbs, and two leg modules corresponding to the left and right lower limbs.
[0014] Preferably, the weight measuring component includes: An L-shaped drive rod, the short side of which is perpendicularly connected to either of the sliding members; The display panel is disposed at one end of the support frame; A drive gear is rotatably mounted on the display panel and meshes with the long side of the drive rod; A pointer, which is coaxially connected to the axis of the drive gear, points to the weight scale set on the display panel; The horizontal displacement of the slider is converted into the rotation of the pointer on the weight scale through the transmission of the drive rod and the drive gear.
[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a pressure-bearing cavity composed of rectangular sleeves and blocks, connected to a supporting airbag. The patient's own weight compresses the cavity to generate air pressure, and a one-way valve inflates the airbag, achieving a passive adaptive match between support force and body weight. This provides stable, flexible support for patients of different weights without external power, fundamentally solving the problem of traditional mattresses being too hard or too soft due to fixed support force. Furthermore, by incorporating a transmission energy-dissipating component consisting of linkages, sliding parts, and tension springs, the multi-link mechanism converts the vertical downward pressure and impacts on the top plate into horizontal movement of the sliding parts. Energy is dissipated through sliding friction and tension springs, preventing the impact energy from rebounding vertically. This provides a soft contact while completely eliminating the "shaking" sensation of traditional soft mattresses, greatly improving transport stability, especially beneficial for fracture and critically ill patients. This invention employs a cross-shaped support frame with transmission components evenly distributed in four directions. This ensures that pressure applied to any position on the top plate plane is effectively converted into horizontal motion and dissipated, keeping the top plate consistently level and resisting tilting and torsion caused by uneven force or vehicle bumps. This significantly improves the dynamic stability and safety of the device in various complex transport environments. Through a zoned monitoring panel integrated into the top plate, temperature sensors, heating elements, and pressure sensors are independently installed in each area, enabling continuous monitoring and active zoned heating of the patient's surface temperature and pressure distribution. This effectively prevents the risk of hypothermia and pressure sores during transport and provides crucial data for subsequent medical analysis. By converting the horizontal displacement of the sliding component in the transmission assembly into pointer rotation on a dial via an L-shaped drive rod and gear mechanism, a purely mechanical weight estimation function is achieved. This provides medical personnel with an intuitive, reliable tool that requires no additional power source for rapid on-site assessment of the patient's condition. Attached Figure Description

Detailed Implementation
[0018] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0019] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0020] like Figures 1 to 6 As shown, this embodiment of the invention provides an emergency transport mattress device with active temperature control and adaptive pressure adjustment. The device is generally rectangular (approximately 1900mm to 2000mm) and approximately 600mm to 650mm wide. Its length is suitable for use in a standard ambulance. From a cross-sectional view, the device mainly includes, from top to bottom: a top plate 1, an adaptive pressure adjustment mechanism 3, and a bottom plate 2. The top plate 1 is the bearing surface that the patient directly contacts, and the bottom plate 2 is the support surface that contacts the transport facility. The two are arranged in parallel and opposite directions. The pressure adaptive adjustment mechanism 3 is arranged between the top plate 1 and the bottom plate 2. The top plate 1 also integrates a physiological parameter monitoring mechanism 4.
[0021] To address the contradiction that traditional transfer mattresses cannot adaptively adjust support based on patient weight, resulting in either excessive pressure or excessive wobbling, this embodiment incorporates a pressure adaptive adjustment mechanism 3, which is the core for achieving adaptive support and energy dissipation. It mainly includes a pressure sensing component 31 and a transmission energy dissipation component 32.
[0022] Specifically, in this embodiment, the pressure sensing component 31 is responsible for converting the patient's weight (vertical load) into a pneumatic pressure signal, and its core is a sealed pressure-bearing cavity. Specifically, this pressure-bearing cavity is formed by a horizontal rectangular sleeve 3111, a first rectangular block 3112, and a second rectangular block 3113. The upper end of the first rectangular block 3112 is fixedly connected to the bottom surface of the top plate 1, and its lower end is slidably and sealingly inserted into the upper opening of the rectangular sleeve 3111. The lower end of the second rectangular block 3113 is fixedly connected to the top surface of the bottom plate 2, and its upper end is slidably and sealingly inserted into the lower opening of the rectangular sleeve 3111. A sliding seal can be achieved between the first rectangular block 3112, the second rectangular block 3113, and the rectangular sleeve 3111 by setting a sealing ring or other means.
[0023] Therefore, when the patient lies on the top plate 1, the top plate 1 presses down, forcing the first rectangular block 3112 and the second rectangular block 3113 to slide into the rectangular sleeve 3111, compressing the air inside the rectangular sleeve 3111 (as the working medium) and increasing the air pressure inside the pressure chamber.
[0024] The rectangular sleeve 3111 has an outlet in the middle of its side wall, which is connected to a fluid pipe 312. The fluid pipe 312 extends upward and its end is connected to a support airbag 313. A one-way valve 315 is installed on the fluid pipe 312. The one-way valve 315 is a commercially available standard part. Its working principle is similar to the one-way valve in a common air pump. It is configured to allow gas to flow unidirectionally from the inside of the rectangular sleeve 3111 to the support airbag 313, preventing backflow. In addition, a vent valve is provided on the support airbag 313 or fluid line 312. The vent valve can be manual or have a structure with a specific vent diameter. Its core function is to establish a passage between the support airbag 313 and the atmosphere when needed. When manually opened or when the system pressure changes, the gas in the airbag can be discharged through the valve, thereby achieving two purposes: first, to quickly deflate the airbag when a hard surface is needed for emergency operations (such as cardiopulmonary resuscitation); second, after the patient leaves, it serves as a low-speed exhaust channel to assist the airbag in slow contraction, so that the entire system can smoothly return to its initial standby state.
[0025] To achieve weight-based passive negative feedback regulation so that patients of different weights can receive matching stable support, the present invention is designed as follows: the heavier the weight, the deeper the top plate 1 is pressed down, the higher the initial air pressure in the pressure-bearing cavity, the more gas is automatically injected into the support airbag 313, and the greater the support area and lifting force provided by the airbag, until it is balanced with the patient's weight, and vice versa; and the whole process is adjusted according to gravity, without the need for electricity or manual intervention.
[0026] On the top surface of the top plate 1, a support plate 314 is also fixedly installed. The middle part of the support plate 314 is machined with a groove 3141 that matches the shape of the support airbag 313. The support airbag 313 is precisely embedded and fixed in the groove 3141, so that it is stably supported and positioned, so that its upper surface is flush with or slightly higher than the upper surface of the support plate 314, together forming a flat support surface.
[0027] To fundamentally solve the harmful vertical elastic rebound and oscillation problems caused by gas compression energy storage in traditional soft supports (such as ordinary inflatable mats), this embodiment includes a transmission energy dissipation component 32 physically linked to the pressure sensing component 31. The core function of this component is to convert vertical pressure and impact kinetic energy into horizontal mechanical motion and dissipate it. The transmission energy dissipation component 32 includes: Support frame 321: It is a cross-shaped frame that is fixedly sleeved on the periphery of rectangular sleeve 3111. Each of the four arms of the support frame 321 has a sliding groove 322 extending along the arm length direction. Sliding members 323: There are four of them, each slidably disposed in one of four sliding grooves 322. A fixing rod 324 is horizontally inserted through each sliding member 323; Linkage 325: For each sliding member 323, a pair of linkages are provided, namely, a first linkage 3251 and a second linkage 3252. The upper end of the first linkage 3251 is rotatably connected to the bottom surface of the top plate 1 via a first hinge shaft, and its lower end is rotatably connected to one end of the fixed rod 324 via a second hinge shaft. The lower end of the second linkage 3252 is rotatably connected to the top surface of the bottom plate 2 via a third hinge shaft, and its upper end is rotatably connected to the other end of the fixed rod 324 via a fourth hinge shaft. In this way, the first linkage 3251, the second linkage 3252, and the fixed rod 324 form an approximately ">" shaped support linkage mechanism in the side view. Energy dissipation element 326: In this embodiment, it is a tension spring. Each sliding groove 322 is provided with a tension spring. One end of the tension spring is connected to the sliding member 323, and the other end is connected to the support frame 321 near the center of the rectangular sleeve 3111. When the sliding member 323 slides outward, it will stretch the tension spring.
[0028] The specific working principle is as follows: When the patient lies down, causing the top plate 1 to bear vertical downward pressure, the top plate 1 moves downward. This movement acts simultaneously on the first connecting rod 3251 and the second connecting rod 3252: the upper end of the first connecting rod 3251 moves downward with the top plate 1, while its lower end pushes the fixed rod 324; at the same time, the lower end of the second connecting rod 3252 is constrained by the bottom plate 2, and its upper end also acts on the same fixed rod 324. This causes the ">" shaped angle formed by the first connecting rod 3251 and the second connecting rod 3252 to be symmetrically reduced. The fixed rod 324 passes through and is fixed to the sliding member 323. Therefore, this movement of reducing the angle is directly converted into a horizontal thrust on the fixed rod 324, driving the sliding member 323 to slide in the sliding groove 322 in a direction away from the center of the rectangular sleeve 3111. This sliding process directly stretches the tension spring, converting part of the vertical impact kinetic energy into the elastic potential energy of the tension spring; at the same time, the friction between the sliding member 323 and the wall of the sliding groove 322 converts another part of the kinetic energy into heat energy dissipation. Throughout the process, the vertical displacement and impact are precisely decomposed by the linkage mechanism and converted into horizontal motion. Its energy is effectively dissipated by the tension spring and friction, thus preventing the formation of a vertical energy storage-release cycle (i.e., rebound) like traditional spring or airbag systems.
[0029] Through the above design, the vertical load is converted into a horizontal thrust driving the sliding member 323 via the linkage mechanism. Its energy is primarily consumed in overcoming sliding friction and the work done by the tension spring, and is dissipated as heat energy, rather than stored and rebounding vertically. This allows the patient to experience a stable sinking sensation, rather than a shaky bouncing, which is particularly beneficial for the safe transport of patients with fractures or after surgery.
[0030] In addition, the cross-shaped support frame 321 and the four-way symmetrical component arrangement ensure that no matter where the pressure is applied on the top plate 1, it can be converted into horizontal motion dissipation, thereby ensuring that the top plate 1 always descends horizontally as a whole, which greatly enhances the anti-overturning and dynamic stability.
[0031] In this embodiment, the physiological parameter monitoring mechanism 4 is integrated into the top plate 1 for real-time collection of key physiological information of the patient, including a weight measurement component 41, a temperature measurement and control component, and a pressure measurement component.
[0032] The upper surface of the top plate 1 (specifically the support plate 314 and the flexible pad layer covering it) is divided and set with multiple independent monitoring plates according to the main pressure-bearing and temperature-regulating parts of the human body. Specifically, these include: a head plate 441 corresponding to the head, a back plate 442 corresponding to the back, a waist plate 443 corresponding to the waist, two arm plates 444 corresponding to the left and right upper limbs, and two leg plates 445 corresponding to the left and right lower limbs.
[0033] Within each monitoring module, there are embedded or laid: The temperature measurement and control assembly comprises: at least one temperature sensor (such as a patch digital temperature sensor) and a corresponding heating element (such as a flexible carbon fiber heating wire or a metal film heating element); the heating element of each plate can be controlled independently. The pressure measurement assembly includes at least one pressure sensor (such as a thin-film pressure sensor) for sensing the pressure distribution in the area. To address the risks of patient heat loss and the lack of real-time physiological data during emergency transport, this device integrates active temperature control and multi-parameter monitoring. The temperature measurement and control components enable zoned active heating to effectively prevent hypothermia, while the distributed pressure sensors monitor pressure distribution, providing data for assessing the risk of pressure ulcers.
[0034] Specifically, the weight measuring component 41 is a purely mechanical measuring device, cleverly linked with the transmission energy-consuming component 32. It includes: L-shaped drive rod 411: Its short side is vertically downward and fixedly connected to the top of any of the sliding members 323; Display panel 412: It is vertically mounted at the end of one of the arms of the support frame 321; Drive gear 413 and pointer 414: The drive gear 413 is rotatably mounted on the back of the display panel 412 via a rotating shaft. The long side of the drive rod 411 extends horizontally, and a rack is machined on its side to mesh with the drive gear 413. The pointer 414 is coaxially connected to the rotating shaft of the drive gear 413 and points to the weight scale 415 printed on the front of the display panel 412.
[0035] This design creatively utilizes the horizontal displacement of the slider 323 in the transmission energy-consuming component to drive the pointer 414, achieving passive weight estimation. Its working logic is as follows: different patient weights result in different degrees of pressure on the top plate 1, leading to different horizontal displacements of the slider 323. This displacement is transmitted through the drive rod 411 and drive gear 413, ultimately translating into different indications on the weight scale 415 by the pointer 414. This provides medical personnel with intuitive and reliable reference information for quickly assessing patient conditions at the transport site.
[0036] In this embodiment, the top plate 1, the support plate 314, and all exposed surfaces can be covered with a waterproof and breathable layer. This layer uses existing porous polymer film materials, which can prevent liquid from seeping into the internal circuitry while allowing air circulation, thus improving comfort. The heating element can be covered with a graphene thermally conductive film to uniformly and quickly dissipate heat. The signal lines of all sensors can be converged to an integrated data interface, which can be connected to an ambulance monitor or hospital information system via wired or wireless means to achieve real-time data upload and provide source data for the smart emergency medical platform.
[0037] In summary, this invention converts vertical pressure into horizontal dissipation through a unique mechanical structure. Combined with the principle of air pressure self-adaptation and integrated monitoring, it effectively solves the prominent problems of poor patient support stability, easy loss of body temperature, and unknown physiological state during emergency transport, providing patients with a safe, comfortable, and intelligent transport environment.
[0038] This invention, through a unique "pressure-bearing cavity-connecting rod-energy dissipation" mechanical structure, simulates the effect of a sandbed: it achieves flexible pressure dispersion through airbags to avoid hard injuries, and eliminates soft rebound through a horizontal energy dissipation mechanism. Combined with adaptive adjustment and integrated monitoring, it resolves the inherent contradiction of human body support during emergency transport, providing patients with safe, stable, and intelligent transport support.
[0039] The working principle and core advantages of this invention lie in its unique mechanical structure design, which fundamentally redefines the support method during emergency transport. When the patient lies on the mattress, their weight acts as a vertical load on the top plate 1. To resolve the inherent contradiction between the "rigid rebound of a hard bed" and the "elastic oscillation of a soft bed" in traditional support structures, the core mechanism of this invention lies in the conversion of force direction and energy dissipation. The downward movement of the top plate 1 will simultaneously drive the connecting rods 325, which are hinged to it and the bottom plate 2 at both ends, to move. This vertically downward force is transmitted and transformed through two paths: First, it acts directly on the pressure-bearing cavity composed of the rectangular sleeve 3111, the first rectangular block 3112, and the second rectangular block 3113, compressing the gas inside and converting it into gas pressure potential energy; Second, by pushing the connecting rods 325 to move, the vertical pressure and bumpy impact are efficiently converted into a horizontal thrust on the sliding member 323, driving the sliding member 323 to move in all directions within the sliding groove 322 of the support frame 321. In this process, the vast majority of the impact energy is consumed in overcoming sliding friction and the work done by the tension spring, and is converted into a small amount of heat energy that is dissipated, rather than storing the energy and forming a vertical reciprocating rebound as in traditional springs or airbags. This fundamentally eliminates the swaying sensation that causes discomfort and secondary injury to the patient, achieving a flexible and stable support base.
[0040] Simultaneously, this mechanical motion directly drives the parallel air pressure regulation system. The downward pressure of the top plate 1 compresses the air inside the rectangular sleeve 3111, creating a higher external air pressure that opens the one-way valve 315, allowing gas to continuously flow into the upper support airbag 313 until its internal pressure reaches equilibrium with the patient's weight distribution. This is a completely passive adaptive process designed to automatically match a stable support state for patients of different weights, without the need for electricity or manual intervention: heavier patients experience a deeper downward movement of the top plate 1 and a higher initial air pressure, automatically inflating the airbag 313 with more gas, resulting in a larger support area and lifting force; lighter patients experience the opposite.
[0041] To achieve superior static and dynamic stability and prevent mattress tipping, the support frame 321 adopts a cross-shaped structure, with sliding grooves 322, sliding elements 323, and connecting rods 325 in all four directions. This symmetrical design ensures that pressure applied at any position on the plane of the top plate 1 is first converted into air pressure changes through the aforementioned pressure-bearing cavities and connecting rods 325, and then efficiently converted into horizontal forces through the corresponding connecting rod mechanism 325, which are then effectively dissipated. As a result, regardless of how the patient lies or how their center of gravity shifts, the top plate 1 always maintains an overall horizontal descent, effectively resisting lateral tilting or torsional tendencies caused by uneven force distribution. This significantly reduces the risk of patient falls or postural injuries during complex transportation conditions such as vehicle turns and bumps.
[0042] This invention forms a complete passive cycle during operation. When the patient leaves the mattress, the device automatically returns to its initial standby state through a built-in reset mechanism. The reset process mainly includes two aspects: First, the stretched spring 3261 releases its stored elastic potential energy, and its rebound force drives the sliding member 323 to slide towards the center, and pushes the top plate 1 back to its original height smoothly through the connecting rod 325. Second, the gas trapped in the support airbag 313 is slowly discharged to the atmosphere through the preset vent valve 316, causing the airbag to gradually contract. This mechanical reset and air pressure release process are carried out in coordination, ensuring that all components are automatically and smoothly reset without any external energy or manual operation, thus preparing for the reception of the next patient.
[0043] From a clinical perspective, this invention comprehensively resolves the inherent contradictions of traditional transport support: it ultimately achieves pressure dispersion through the airbag 313, avoiding the risk of pressure sores associated with "hard support"; and through a unique energy dissipation mechanism, it eliminates the elastic oscillations of "soft support". Combined with integrated body temperature maintenance and monitoring functions, this device creates a safe, comfortable, and intelligent transport microenvironment for critically ill patients.
