Description

Technical Field

[0001] This invention relates to the field of emergency rescue technology, specifically to a multifunctional emergency safety transport device for infants and young children. Background Technology

[0002] In emergency rescue scenarios such as fires and sudden disasters, infants and young children are a high-risk group during emergency evacuations due to their lack of self-protection abilities and underdeveloped physical functions. Current technologies for transferring infants and young children mostly consist of conventional carrying protective gear or simple storage bags. These tools generally suffer from limited protective capabilities, providing only basic physical isolation and failing to address the complex dangers of dense smoke, insufficient oxygen, and excessively high temperatures in fire scenes. Furthermore, traditional transfer tools do not consider the age-appropriateness of infants and young children, lack specialized fixing structures for different sizes, and do not specify the appropriate carrying capacity for different age groups. This makes it easy for infants and young children to shift or move out of the protective range, increasing the risk of accidents during transfer.

[0003] Furthermore, existing transfer tools struggle to balance portability and functionality. Some protective devices, due to their heavy materials and complex structures, are difficult for users to carry and operate, failing to meet the need for rapid escape in fire situations. Lightweight transfer tools, on the other hand, lack sufficient protective capabilities, failing to effectively isolate external fire and heat sources, and unable to monitor and control air quality inside the compartment in real time. Moreover, visual obstructions and noise in a fire environment make it difficult for rescuers to quickly locate trapped infants and young children. Existing tools lack effective location guidance designs, further prolonging rescue time and reducing the survival rate of infants and young children. Simultaneously, infants and young children are prone to panic in disaster environments, and existing transfer tools lack corresponding calming mechanisms; physical struggles caused by panic further increase the difficulty of the transfer operation.

[0004] Crucially, traditional fire and emergency personnel often carry infants by hand when transferring them, which cannot free their hands in scenarios such as high-altitude cable transfers, greatly affecting the efficiency and safety of the transfer. Furthermore, existing tools only focus on the protection of infants and do not consider the safety of the transfer personnel. If the transfer personnel are injured due to high temperatures or smoke poisoning during the transfer, it will directly lead to the failure of the infant transfer. Summary of the Invention

[0005] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a multifunctional emergency safety transfer device for infants and young children. It solves the problems of limited protection and poor portability of infant transfer tools during fires, inability to isolate dense smoke and regulate the air inside the chamber, and lack of positioning and comforting designs, which easily lead to high transfer risks and low rescue efficiency.

[0016] 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.

[0017] like Figure 1-4 As shown, this embodiment of the invention provides a multifunctional emergency safety transport device for infants and young children, comprising: The protective chamber 5 is made of fire-resistant, high-temperature resistant, and lightweight materials. It is a sealed structure with a dedicated installation space located near the underside of the safety seat 3. This space houses an oxygen supply device, an internal air detection device, a control module, and an oxygen cylinder. An external gas detection device is installed on the exterior of the protective chamber 5. The control module has automatic and manual modes. In automatic mode, when the oxygen concentration inside the chamber is low or the CO / CO2 concentration is high, and the external smoke concentration and CO / CO2 content are below the threshold, the air intake filter is activated to draw in external gas to supply air to the chamber. When the chamber... When the internal oxygen concentration is low or the CO / CO2 concentration is high, and the external smoke concentration and CO / CO2 content reach the threshold, the oxygen supply device is activated to supply air to the chamber. In manual mode, the air intake filter can be manually selected to draw air into the chamber or to supply air through the internal oxygen supply device. A return spring 10 is fixedly installed at the internal opening on one side of the protective chamber 5. A sliding air pipe 9 is fixedly installed at the upper end of the return spring 10, and the lower end of the sliding air pipe 9 is connected to the oxygen supply device inside the protective chamber 5. An airflow hole 4 is provided on one side of the inside of the protective chamber 5. Filter cotton is installed at the airflow hole 4 to perform secondary filtration of the gas entering the chamber.

[0018] Specifically, in the above-mentioned embodiments, the fire-resistant and high-temperature resistant material selected for the protective chamber 5 can withstand temperatures no lower than those commonly found in fire scenes, and the density of the lightweight material is in a low specific gravity range, ensuring structural strength while controlling the overall weight; the external gas detection device can monitor the concentration of smoke, carbon monoxide, carbon dioxide, and other harmful components in the fire scene in real time, and the preset concentration threshold is set according to infant respiratory safety standards; the filtration levels of the air intake filter are adapted to the particle diameter and harmful gas components of the dense smoke in the fire scene, and can perform multi-level purification of the external air; the monitoring frequency of the air detection device inside the chamber is fixed, and the response delay of the control module is within a short range, ensuring timely gas regulation. The oxygen supply device is connected to the air supply channel inside the chamber and the airbag of the safety seat 3 through internal branch pipes. Independent control valves are provided at the branch pipes to achieve precise switching of the air supply path, which can not only replenish oxygen to the entire chamber, but also inflate the airbag separately, solving the technical problem of a single pipeline meeting different air supply needs at the same time, and ensuring the coordinated realization of infant breathing and body position restraint functions.

[0019] The protective chamber 5 is equipped with reflective strips and flashing indicator lights on its surface, and a whistle and flashlight are attached to its outer side. The protective chamber 5 is equipped with a speaker for playing soothing music. Storage bags 8 are fixed on both sides of the protective chamber 5. The storage bags 8 are made of wear-resistant and flame-retardant material and are used to store emergency supplies.

[0020] Specifically, in the above-mentioned specific embodiments, the reflective strips on the surface of the protective compartment 5 are made of a material with a high reflectivity and are distributed in multiple conspicuous parts such as the front and sides of the compartment. The flashing frequency of the flashing indicator lights is within the appropriate range for fire rescue identification and can continuously emit optical signals in low-visibility environments at fire scenes. The decibel value of the whistle meets the effective propagation standard in fire scene environments, and the illumination range of the flashlight meets the needs of short-distance signal transmission in fire scenes. The volume adjustment range of the speaker is adapted to the auditory tolerance of infants and young children, and the pre-stored soothing music is a type of soothing pure music, and the playback duration can be set according to the transfer needs. The opening of the storage bag 8 is equipped with a Velcro closure, the capacity is adapted to the size of common emergency items, and the wear-resistant and flame-retardant material can resist the wear and high temperature effects of the fire scene environment. This design improves the efficiency of rescue identification through optical and acoustic dual prompting methods, alleviates the panic of infants and young children with soothing music, and achieves orderly storage of emergency items through a dedicated storage bag.

[0021] The sealing cover 1 is fixedly connected to the lower front side of the protective chamber 5 at its lower end. The two are sealed together by a sealing zipper, and the sealing zipper is provided with a Velcro sealing strip on the outside. The sealing cover 1 is provided with a transparent observation window 2 made of heat-resistant transparent material, which is used to observe the state of the infants and to interact with and soothe them. The interior is provided with a fire-retardant limiting sponge 2 near the top of the child's head.

[0022] Specifically, in the above-mentioned specific embodiments, the sealing zipper and Velcro sealing tape form a double sealing structure, and the sealing level can prevent dense smoke from the fire from entering the interior of the chamber through gaps; the heat-resistant material of the transparent observation window 2 can withstand the high temperature radiation of the fire without fogging or cracking, and the light transmittance meets the requirements for clear observation of the situation inside the chamber; the density of the limiting sponge 2 is in the range of softness and support, and it is designed to fit the physiological curve of the infant's head. The fire-retardant material has an ignition point higher than the common temperature in the fire. This design strengthens the airtightness of the chamber through the double sealing structure, the transparent observation window enables real-time monitoring of the infant's condition, and the limiting sponge flexibly limits the infant's head to reduce collision injuries caused by head shaking during transfer.

[0023] There are three safety seats 3, which are fixedly installed inside the protective compartment 5. The safety seat 3 is equipped with an airbag, which is connected to an oxygen supply device. After the infant is placed in the safety seat 3, oxygen can be introduced into the airbag to make it inflate appropriately, thereby achieving the function of restraining the infant. The safety seat 3 is also equipped with a seat belt to secure the infant. It is worth noting that the car seat 3-piece set comes in three sizes according to the infant's age, to suit different usage scenarios: Type 1 (0-1 year old): The protective housing 5 can be fixedly installed with 3 safety seats 3, with a seat spacing of ≥30cm, suitable for infants aged 0-1 years (weight ≤10kg). Type 2 (1-2 years old): The protective compartment 5 can also be fixedly installed with 2 safety seats 3, with a seat spacing of ≥35cm, suitable for infants aged 1-2 years (weight 10-15kg). Type 3 (2-3 years old): The protective housing 5 can also be fixedly installed with a safety seat 3. The seat width is ≥40cm and it is suitable for infants aged 2-3 years (weight 15-20kg).

[0024] Specifically, in the above-mentioned specific embodiments, the size of the safety seat 3 is designed according to the body size range of infants under 3 years old. The two seats are arranged side by side, with the spacing adapted to the comfort of infants and the utilization of cabin space. The inflation volume of the airbag can be adjusted through the branch valve of the oxygen supply device. After inflation, the airbag conforms to the body contour of the infant, forming a flexible limiting barrier. The seat belt is made of high-strength and soft flame-retardant material, and the fixing method adopts a five-point fixing structure. The fixing force can be adjusted within a safe range. This design, through the dual protection of seat size adaptation and "airbag limiting + seat belt fixing", ensures the stability of the infant's position in the cabin. The cushioning effect of the airbag can reduce the impact of vibration during the transfer process, improving the safety and comfort of the infant.

[0025] It also includes an oxygen supply mask assembly, which includes an extension strap 6, a connecting buckle 12, a linkage rope 11, and an oxygen supply mask 7. One end of the linkage rope 11 is fixedly connected to the lower end of one side of the sliding air tube 9, and the other end is fixedly connected to the extension strap 6. The other end of the extension strap 6 is provided with a connecting buckle 12. The oxygen supply mask 7 is snapped onto one side of the extension strap 6 and connected to the sliding air tube 9. When the oxygen supply mask 7 is pulled, the extension strap 6 and the linkage rope 11 drive the sliding air tube 9 to move outward. When the external smoke concentration is too high, the user and the infant share the oxygen provided by the oxygen supply device.

[0026] Specifically, in the above-mentioned embodiments, the size of the oxygen supply mask 7 is adapted to the facial contours of infants and users, and its sealing performance can prevent unpurified gas from entering the breathing channel; the extension stroke of the sliding air tube 9 meets the displacement requirements of the oxygen supply mask 7 during use, and the elastic coefficient of the return spring 10 can drive the sliding air tube 9 to automatically return to its original position after use, ensuring that the sealing of the chamber is not affected; the length of the extension strap 6 is adapted to the user's wearing and storage needs, and the connecting buckle 12 can fix the extension strap 6 to the inner wall of the chamber to avoid shaking interference; the oxygen supply device delivers oxygen to the oxygen supply mask 7 through the sliding air tube 9, realizing a shared air source design for "overall air supply in the chamber" and "individual air supply to the mask", which not only ensures the stability of the overall breathing environment in the chamber, but also provides precise oxygen supply to users and infants through the mask in special circumstances, improving the flexibility and reliability of respiratory protection.

[0027] Two shoulder straps 13 are fixedly installed at the rear end of the protective cabin 5. A safety buckle 14 is installed between the two shoulder straps 13. The safety buckle 14 is used to fasten the two shoulder straps 13 to prevent the transfer cabin from shaking or falling off during the transfer process. The shoulder straps 13 are made of the same fireproof, high temperature resistant and lightweight material as the protective cabin 5. The part of the shoulder straps 13 that comes into contact with the human body is provided with a flexible cushioning layer.

[0028] Specifically, in the above-mentioned specific embodiments, the width of the shoulder strap 13 is designed according to ergonomics, and the flexible cushioning layer is made of breathable and flame-retardant sponge material, which can reduce the pressure when carrying the load; the locking force of the safety buckle 14 is adjustable, and the spacing of the shoulder strap after buckling is adapted to the body shape of different users, ensuring the fit between the container and the user's back during the transfer process; the aperture size of the airflow hole 4 is matched with the gas flow rate, and the filtration accuracy of the filter cotton is higher than the secondary filtration standard of the air intake filter device, which can perform fine secondary filtration on the gas entering the container, further removing tiny particles and residual harmful components in the gas. This design improves the air quality inside the container through secondary filtration of the airflow hole. The ergonomic design of the shoulder strap and the locking function of the safety buckle combine to enhance the carrying stability of the transfer container and reduce the physical exertion of the user during the escape from the fire.

[0029] Working principle: This device forms a backpack-like carrying structure through the combination of the protective compartment 5 and the carrying strap assembly. The safety buckles 14 between the carrying straps 13 can lock and fix the carrying straps 13, limiting the displacement of the transfer compartment on the user's back and ensuring the stability of the structure during the transfer. After the user places the infant or toddler in the safety seat 3 inside the compartment, the safety belt is used for initial fixation. Then, the oxygen supply device inflates the airbag to form a flexible limit, establishing the safe protection range for the infant or toddler inside the compartment and eliminating the risk of protection failure due to body movement.

[0030] The control module adjusts the gas supply mode according to the automatic mode logic. The external gas detection device and the internal air detection device work together to collect environmental and internal gas data. When the oxygen concentration inside the chamber is low or the CO / CO2 concentration is high, and the smoke concentration and CO / CO2 content outside the chamber are below the threshold, the air intake filter is activated to draw in external gas. After being purified through multiple layers, the gas enters the chamber through airflow hole 4 to meet the breathing needs of infants and young children. When the external gas indicators reach the threshold, the control module switches to the oxygen supply device mode, which delivers oxygen into the chamber through internal pipelines to maintain the stability of the breathing environment inside the chamber. In manual mode, users can directly switch the gas supply mode according to the actual scenario, improving the flexibility of emergency response.

[0031] When the external smoke concentration is too high, the user can pull the oxygen supply mask 7, which, through the extension strap 6 and the linkage rope 11, moves the sliding air tube 9 outward. After wearing the oxygen supply mask 7, the user and the infant share the oxygen provided by the oxygen supply device, ensuring the breathing safety of both parties. The reflective strips and flashing indicator lights on the surface of the protective chamber 5 transmit position information through optical signals. The whistle and flashlight can provide acoustic and optical cues, enhancing signal recognition in the fire scene and assisting rescuers in quickly locating targets. The speaker inside the chamber plays preset soothing music to regulate the infant's emotional state, reduce physical struggles caused by panic, and ensure the continuity of the transfer operation. The transparent observation window allows the user to monitor the infant's condition in real time, supporting interactive reassurance and promoting the orderly conduct of the emergency transfer process.

[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.
