Description

Technical Field

[0001] This invention relates to the field of medical emergency equipment technology, and in particular to a portable first aid kit. Background Technology

[0002] Airway obstruction is a common clinical emergency with rapid progression. Even mild obstruction can lead to suffocation if not treated promptly. In emergencies, invasive procedures such as cricothyrotomy and tracheotomy are necessary to save lives. In primary healthcare settings (such as community health service centers and village clinics) and outdoor emergency scenarios, existing general-purpose first-aid kits are inadequate for the graded resuscitation needs of airway obstruction, lack specific operational guidelines, and suffer from varying levels of expertise among primary healthcare personnel. The airway obstruction resuscitation process is complex, with different degrees of obstruction requiring different procedures. The lack of a dedicated operational guidance system in existing first-aid kits, relying solely on personnel experience, easily leads to equipment misuse, procedural confusion, and delays in receiving optimal treatment. Therefore, there is an urgent need for a first-aid kit with a standardized procedure for primary care resuscitation. Summary of the Invention

[0006] The first aid kit has a storage space and an opening for taking out and putting in the kit, which connects the storage space to the external environment.

[0007] The rotating process device includes a rotating shaft and multiple storage boxes; the rotating shaft passes through the first aid box from the external environment and extends to the accommodating space, and is rotatably connected to the first aid box; multiple storage boxes are circumferentially spaced around the rotating shaft and rotate with the rotating shaft; each storage box is located within the accommodating space; the storage box is used to hold first aid supplies.

[0008] The limiting mechanism is connected to the rotating shaft via a transmission, and the limiting mechanism is used to restrict the unidirectional rotation of the rotating shaft.

[0009] Furthermore, the rotating shaft has a driving part, a supporting part, and a limiting part, which are sequentially connected. The supporting part is located within the accommodating space, while the driving part and the limiting part are located outside the accommodating space and on opposite horizontal sides of the accommodating space. The driving part is provided with a driving knob for the operator to operate and drive the rotating shaft. Each of the storage boxes is circumferentially spaced around the rotating shaft and mounted on the supporting part. The limiting part is connected to the limiting mechanism so that the rotating shaft can be restricted in its rotation direction by the limiting mechanism.

[0010] Furthermore, the limiting mechanism includes a meshing gear, a mounting bracket, a meshing block, and a limiting plate. The meshing gear is sleeved around the periphery of the limited portion. The mounting bracket is mounted on the outer wall of the first aid box. The mounting bracket is provided with a guide rail. The meshing block is slidably mounted on the guide rail and can mesh with the meshing gear. The direction in which the meshing block points towards the limiting plate is defined as a first direction. The limiting plate is disposed on the guide rail and located on one side of the meshing block in the direction of the guide rail. The limiting plate is used to prevent the meshing block from sliding along the first direction.

[0011] Furthermore, the limiting mechanism also includes an elastic reset member, which is sleeved on the guide rail and is used to drive the engagement block to engage with the engagement gear.

[0012] Furthermore, the portable first aid kit also includes multiple mounting components, with each first aid box having one of the mounting components; the mounting component includes a mounting rod and a support plate, the mounting rod is mounted on the support part, the mounting rod and the support plate are hinged to each other, the support plate connects to the storage box and supports the storage box; the support plate has a counterweight, the counterweight ensures that the opening of the storage box always faces upward.

[0013] Furthermore, the mounting rod is provided with a mounting through hole, the extension direction of which is consistent with the length of the rotating shaft, and the bearing plate is provided with a mounting post, which is rotatably sleeved on the mounting through hole.

[0014] Furthermore, each of the aforementioned mounting components is provided with multiple mounting rods and multiple support plates, and each of the mounting rods is hinged to one of the support plates.

[0015] Furthermore, each of the carrier plates is provided with a sliding groove, and the storage box is provided with at least two sliders, each slider slidingly engaging with one of the sliding grooves.

[0016] Furthermore, the portable first aid kit also includes multiple locking devices, each of the mounting components being equipped with one of these locking devices. Each locking device includes a mounting base, an operating lever, an electromagnet, a control module, and a contact switch. The mounting base is mounted on the mounting lever, and the operating lever is slidably mounted on the mounting base. The sliding path of the operating lever on the mounting base is an axis pointing towards the rotation shaft. The first aid kit has a guide groove, through which the operating lever passes. The contact switch is located on the mounting base and on the sliding path of the operating lever on the mounting base. The contact switch is used to sense the relative position of the operating lever on the mounting base. The sliding path has a locking groove corresponding to the position of the first aid kit, and the locking groove communicates with the guide groove. The electromagnet is mounted on a sliding groove, and the electromagnet is used to switch the sliding groove between a magnetic sliding groove and a non-magnetic sliding groove. The control module is electrically connected to the electromagnet and the contact switch, and the control module is used to control the on / off state of the electromagnet based on the signal from the contact switch.

[0017] Furthermore, the portable first aid kit also includes an operation guidance device, which includes an information reading module, multiple information modules, and a guidance module. The information reading module is installed in the accommodating space and located at the retrieval port. Each of the information modules is installed on an operating lever belonging to a different locking device and slides along the operating lever to approach the information reading module and be read. The guidance module is electrically connected to the information reading module and is used to present the corresponding information read by the information reading module from the corresponding information module to the operator.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The rotating process device includes a rotating shaft and multiple storage boxes; the rotating shaft passes through the external environment into the first aid box and extends to the accommodating space, and is rotatably connected to the first aid box; multiple storage boxes are circumferentially spaced around the rotating shaft and rotate with the rotating shaft; each storage box is located within the accommodating space; the storage boxes are used to hold first aid supplies; this invention classifies and loads first aid supplies into multiple storage boxes, and arranges them spaced around the rotating shaft according to the sequence of the primary care rescue process. Rotating this rotating shaft allows each storage box to be aligned with the access port in sequence, realizing the orderly and streamlined retrieval of first aid supplies. This effectively avoids the problems of mixed and disorderly storage and retrieval of items in existing first aid kits, providing a clear process for primary care rescue and reducing delays in rescue due to item searching.

[0020] 2. Based on the transmission connection between the limiting mechanism and the rotating shaft, the limiting mechanism is used to restrict the unidirectional rotation of the rotating shaft. This invention, through the unidirectional limiting effect of the limiting mechanism, allows the rotating shaft to rotate only in the preset direction of the emergency rescue process. This effectively prevents medical personnel from making mistakes during emergency rescues, such as rotating the shaft in the opposite direction and disrupting the arrangement of the storage boxes. It also ensures that the retrieval of emergency supplies always follows the preset process, further standardizing grassroots emergency rescue operations, avoiding emergency rescue errors caused by chaotic procedures, and improving the standardization and reliability of rescue work.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See Figures 1-3 A preferred embodiment of the present invention provides a portable first aid kit, comprising: a first aid box 1, a rotating flow device 2, and a limiting mechanism 3;

[0033] The first aid box 1 has a accommodating space 11 and a take-out opening 12, which connects the accommodating space 11 to the external environment.

[0034] The rotating process device 2 includes a rotating shaft 21 and multiple storage boxes 22; the rotating shaft 21 passes through the external environment into the first aid box 1 and extends to the accommodating space 11, and is rotatably connected to the first aid box 1; the multiple storage boxes 22 are circumferentially spaced around the rotating shaft 21 and rotate with the rotating shaft 21; each storage box 22 is located within the accommodating space 11; the storage box 22 is used to hold first aid supplies.

[0035] The limiting mechanism 3 is connected to the rotating shaft 21 in a transmission manner, and the limiting mechanism 3 is used to limit the unidirectional rotation of the rotating shaft 21.

[0036] The working principle of this invention is as follows: First, various first-aid supplies are categorized and loaded into multiple storage boxes 22 (each storage box 22 has an opening that can be opened and closed) according to the standard procedure for basic emergency rescue. The storage boxes 22 are then arranged around the rotating shaft 21 at intervals according to the sequence of the emergency rescue procedure, ensuring that different first-aid supplies required for different rescue steps correspond to different storage boxes 22, and that the arrangement of the storage boxes 22 perfectly matches the rescue procedure. (Each storage box 22 is assigned a serial number or contains the supplies needed for the first step of the rescue procedure.) The storage box 22 for emergency supplies is designed with different colors on its exterior. The end face of the emergency box 1 that is rotated and connected by the rotating shaft 21 is designed as a visible panel. The user can see the position of the storage box 22 in the accommodating space 11 through this visible panel, and then determine the position of the storage box 22 containing the emergency supplies needed in the first step of the rescue process. When medical personnel are performing primary rescue and need to retrieve emergency supplies, they can directly rotate the rotating shaft 21 located on the outside of the emergency box 1 to rotate the storage box 22 containing the emergency supplies needed in the first step of the rescue process to the retrieval port 12. When the rotating shaft 21 rotates, it drives multiple storage boxes 22 fixedly connected to it to rotate synchronously. Since the multiple storage boxes 22 are arranged circumferentially around the rotating shaft 21 according to the sequence of the primary care emergency procedure, during rotation, each storage box 22 will sequentially align with the access port 12 on the first aid kit 1. Medical personnel can directly access the corresponding emergency supplies in the storage box 22 that is currently rotated to the access port 12 through the access port 12, achieving orderly access according to the emergency procedure and avoiding confusion or omission of items. At the same time, the limiting mechanism 3, which is connected to the rotating shaft 21, will also function synchronously. It only allows the rotating shaft 21 to rotate unidirectionally according to the preset emergency procedure. If medical personnel mistakenly attempt to rotate the rotating shaft 21 in the opposite direction to disrupt the arrangement of the storage boxes 22, the limiting mechanism 3 will immediately activate, locking the rotating shaft 21 to prevent reverse rotation and forcibly ensuring that medical personnel always access emergency supplies according to the preset emergency procedure, ensuring that the emergency work is carried out in a standardized and orderly manner.

[0037] Obviously, the rotating process device 2 includes a rotating shaft 21 and multiple storage boxes 22. The rotating shaft 21 passes through the external environment into the first aid box 1 and extends to the accommodating space 11, and is rotatably connected to the first aid box 1. The multiple storage boxes 22 are installed around the rotating shaft 21 at intervals and rotate with the rotating shaft 21. Each storage box 22 is located in the accommodating space 11 and is used to hold first aid supplies. This invention classifies and loads first aid supplies into multiple storage boxes 22 and arranges them at intervals around the rotating shaft 21 according to the order of the primary rescue process. Rotating the rotating shaft 21 allows each storage box 22 to be aligned with the access port 12 in sequence, realizing the orderly and streamlined access to first aid supplies. This effectively avoids the problems of mixed and disorderly storage and access of items in existing first aid kits, providing a clear process for primary rescue and reducing delays in rescue due to item searching.

[0038] Based on the transmission connection between the limiting mechanism 3 and the rotating shaft 21, the limiting mechanism 3 is used to restrict the unidirectional rotation of the rotating shaft 21. This invention, through the unidirectional limiting effect of the limiting mechanism 3, allows the rotating shaft 21 to rotate only in the preset direction of the emergency rescue process. This effectively prevents medical personnel from making mistakes during emergency rescues, such as rotating the rotating shaft 21 in the opposite direction and disrupting the arrangement order of the storage box 22. It also ensures that the retrieval of emergency supplies always follows the preset process, further standardizing grassroots emergency rescue operations, avoiding emergency rescue errors caused by chaotic procedures, and improving the standardization and reliability of rescue work.

[0039] refer to Figure 3 , Figure 5 and Figure 7Preferably, the rotating shaft 21 has a driving part 211, a supporting part 212, and a limiting part 213. The driving part 211, the supporting part 212, and the limiting part 213 are connected in sequence. The supporting part 212 is located inside the accommodating space 11, and the driving part 211 and the limiting part 213 are located outside the accommodating space 11 and on opposite horizontal sides of the accommodating space 11. The driving part 211 is provided with a driving knob 214 for the operator to operate and drive the rotating shaft 21. Each of the storage boxes 22 is circumferentially spaced around the rotating shaft 21 and mounted on the supporting part 212. The limiting part 213 is connected to the limiting mechanism 3 so that the rotating shaft 21 can be restricted in its rotation direction by the limiting mechanism 3. The drive knob 214 allows the operator to quickly drive the rotating shaft 21, improving operational convenience and adapting to grassroots emergency rescue scenarios. The built-in support part 212 prevents interference between the storage box 22 and the inner wall of the first aid box 1 when rotating, while the externally positioned limiting part 213 allows for a more reasonable installation of the limiting mechanism 3, more stable transmission, and reliable one-way limiting. The three components have clear division of labor and a compact layout, ensuring orderly rotation and retrieval of the storage box 22 while simplifying operation and assembly, balancing portability and practicality, and enabling streamlined item retrieval without complex operations.

[0040] refer to Figure 1 Preferably, the limiting mechanism 3 includes a meshing gear 31, a mounting bracket 32, a meshing block 33, and a limiting plate 34. The meshing gear 31 is sleeved around the periphery of the limited portion 213. The mounting bracket 32 ​​is mounted on the outer wall of the first aid box 1. The mounting bracket 32 ​​is provided with a guide rail 321. The meshing block 33 is slidably mounted on the guide rail 321 and can mesh with the meshing gear 31. The direction in which the meshing block 33 points to the limiting plate 34 is defined as the first direction. The limiting plate 34 is provided on the guide rail 321 and is located on one side of the meshing block 33 in the direction of the guide rail 321. The limiting plate 34 is used to prevent the meshing block 33 from sliding along the first direction. The meshing gear 31 is sleeved with the limited part 213, and the transmission is direct and reliable. The limiting force can be accurately applied to the rotating shaft 21 to ensure stable limiting effect. The mounting bracket 32 ​​is set on the outer wall of the first aid box 1 without occupying the internal storage space 11, ensuring sufficient storage of first aid supplies. The guide rail 321 guides the meshing block 33 to slide, and the movement path is fixed to avoid jamming or deviation and ensure smooth meshing. The limiting plate 34 blocks the meshing block 33 from sliding in the first direction, realizing one-way locking of the meshing gear 31. It only allows the rotating shaft 21 to rotate in the direction of the preset rescue process. If it is reversed, it is locked, which forces and standardizes the rescue operation, prevents misoperation from disrupting the process, and improves the standardization and reliability of grassroots rescue.

[0041] refer to Figure 1Preferably, the limiting mechanism 3 further includes an elastic reset member 35, which is sleeved on the guide rail 321. The elastic reset member 35 is used to drive the biting block 33 to engage with the biting gear 31. The elastic reset member 35 can apply a continuous elastic force to the biting block 33, driving the biting block 33 to always maintain a stable engagement with the biting gear 31. This effectively prevents the biting block 33 from accidentally disengaging from the biting gear 31 due to bumps at the grassroots rescue site or vibrations of the rotating shaft 21. This ensures the continuous reliability of the one-way limiting function of the limiting mechanism 3, thereby ensuring that the rotating shaft 21 can only rotate in the preset rescue process direction, preventing misoperation from disrupting the arrangement of the storage box 22, and further standardizing grassroots rescue operations. At the same time, the elastic reset member 35 is sleeved on the guide rail 321, which is compact and does not occupy extra space. It does not interfere with the normal sliding of the biting block 33 along the guide rail 321, adapting to the design requirements of portable and miniaturized first aid kits. The elastic reset element 35 can be a compression spring, a disc spring, or a rubber elastic sleeve.

[0042] refer to Figure 3 , Figure 5 and Figure 6 Preferably, the portable first aid kit further includes multiple mounting components 4, with each first aid box 1 equipped with one of the mounting components 4. Each mounting component 4 includes a mounting rod 41 and a support plate 42. The mounting rod 41 is mounted on the support portion 212 and hinged to the support plate 42. The support plate 42 connects to and supports the storage box 22. The support plate 42 has a counterweight 421, which ensures the opening of the storage box 22 always faces upwards. The hinged structure, combined with the counterweight 421, utilizes gravity to ensure the opening of the storage box 22 remains upwards during circumferential rotation with the rotating shaft 21. This effectively prevents the opening from tilting or downwards during rotation, thus avoiding the falling or scattering of first aid items. It ensures stable storage of first aid items during retrieval, prevents delays in rescue due to spillage, and improves the safety and reliability of basic rescue operations. Meanwhile, this structure is purely mechanical, requiring no electronic control or sensors, making it simple, low-cost, and with a low failure rate, suitable for the portable and durable requirements of first aid kits. The counterweight 421 can be made of metal, lead, or high-density plastic.

[0043] refer to Figure 3 and Figure 5Preferably, the mounting rod 41 is provided with a mounting through hole 411, the extension direction of which is consistent with the length of the rotating shaft 21. The bearing plate 42 is provided with a mounting post 422, which is rotatably fitted into the mounting through hole 411. The fitting of the mounting post 422 and the mounting through hole 411, together with the counterweight 421, reliably ensures that the opening of the storage box 22 always faces upward, preventing emergency supplies from falling due to tilting during rotation. The mounting through hole 411 extends along the length of the rotating shaft 21, making the rotation axis 21 line of the bearing plate 42 parallel to the rotating shaft 21. This ensures a more stable posture of the storage box 22 when it rotates circumferentially with the rotating shaft 21, without deviation or jamming, guaranteeing smooth access. This fitting structure is simple and compact to assemble, does not occupy extra space, is suitable for the portable design of first aid kits, and its purely mechanical structure is durable and has a low failure rate. The mounting post 422 can be made of metal pin or hard plastic shaft; a wear-resistant bushing can be added to the inner wall of the mounting through hole 411 to reduce rotational friction and extend the service life of the component.

[0044] Preferably, each of the mounting components 4 is provided with multiple mounting rods 41 and multiple support plates 42, and each mounting rod 41 is hinged to one of the support plates 42. The multiple mounting rods 41 are hinged to the multiple support plates 42 one-to-one, providing stable support for the support plates 42 and the storage box 22 from multiple points. This effectively avoids the load concentration on a single mounting rod 41, which could cause the support plate 42 to tilt, break, or loosen at the hinge, significantly improving the stability and structural strength of the storage box 22. This ensures that the storage box 22 remains stable as it rotates with the rotating shaft 21 and adjusts its own posture, preventing emergency supplies from spilling. The mounting rods 41 can be made of stainless steel or high-strength engineering plastic; anti-slip and wear-resistant pads can be added to the hinges to reduce wear and ensure smooth rotation and prevent loosening.

[0045] refer to Figure 5 and Figure 6 Preferably, each of the supporting plates 42 is provided with a sliding groove 423, and the storage box 22 is provided with at least two sliders 221, each slider 221 slidingly engaging with one of the sliding grooves 423. The sliding engagement of the sliding grooves 423 and the sliders 221 enables the detachable connection between the storage box 22 and the supporting plate 42, facilitating the individual disassembly of the storage box 22 for cleaning, disinfection, or replenishment of first aid supplies, thus meeting the needs of frequent use and regular maintenance of basic first aid kits; the at least two sliders 221 form a multi-point engagement with the sliding grooves 423, ensuring precise positioning and even force distribution, ensuring that the storage box 22 does not shift or fall off when rotating with the rotating shaft 21 and adjusting its own posture, preventing the spillage of first aid supplies. The sliding grooves 423 can be T-shaped, dovetail, or rectangular; the sliders 221 can be made of wear-resistant plastic or metal blocks to ensure smooth sliding and stable positioning.

[0046] refer to Figure 2 , Figure 4 and Figure 5 Preferably, the portable first aid kit further includes multiple locking devices 5, each of the mounting components 4 being equipped with one locking device 5. Each locking device 5 includes a mounting base 51, an operating lever 52, an electromagnet 53, a control module 54, and a contact switch 55. The mounting base 51 is mounted on the mounting lever 41, and the operating lever 52 is slidably mounted on the mounting base 51. The sliding path of the operating lever 52 on the mounting base 51 is along the axis pointing towards the rotating shaft 21. The first aid kit 1 has a guide groove 13, through which the operating lever 52 passes. The contact switch 55 is located on the mounting base 51 and is positioned within... The operating lever 52 slides along the mounting base 51. The contact switch 55 senses the relative position of the operating lever 52 on the mounting base 51. The sliding path has a locking groove 14 corresponding to the position of the first aid box 1. The locking groove 14 communicates with the guide groove 13. The electromagnet 53 is installed on the slide groove 423. The electromagnet 53 is used to switch the slide groove 423 to a magnetic slide groove 423 or a non-magnetic slide groove 423. The control module 54 is electrically connected to the electromagnet 53 and the contact switch 55. The control module 54 is used to control the on / off state of the electromagnet 53 according to the signal from the contact switch 55. When the storage box 22 rotates with the rotating shaft 21 to the position of the retrieval port 12, the operating lever 52 can slide along the guide groove 13 and lock into the locking groove 14 of the storage box 22, accurately fixing the storage box 22 and ensuring that the opening of the storage box 22 is always aligned with the retrieval port 12, facilitating medical personnel to quickly and stably retrieve first aid supplies and improving rescue efficiency. Contact switch 55 senses the position signal of operating lever 52, and control module 54 automatically controls the on / off state of electromagnet 53. When rotating shaft 21 drives storage box 22 to rotate, electromagnet 53 can switch slide 423 to magnetic slide 423, so that slide 423 and slider 221 of storage box 22 form magnetic attraction. The magnetic attraction force counteracts the centrifugal force generated by rotation, effectively preventing emergency supplies in storage box 22 from being thrown out due to centrifugal force, avoiding items from scattering, contamination or loss, and ensuring stable storage of emergency supplies during rotation. Among them, electromagnet 53 can be miniature DC electromagnet 53 or suction cup electromagnet 53; contact switch 55 can be micro switch or inductive switch.

[0047] refer to Figure 4 and Figure 5Preferably, the portable first aid kit further includes an operation guidance device 6, which includes an information reading module 61, multiple information modules 62, and a guidance module 63. The information reading module 61 is installed in the accommodating space 11 and located at the retrieval port 12. Each of the information modules 62 is respectively installed on an operating lever 52 belonging to a different locking device 5, and slides with the operating lever 52 to approach the information reading module 61 and be read. The guidance module 63 is electrically connected to the information reading module 61 and is used to present the corresponding information read by the information reading module 61 from the corresponding information module 62 to the operator. This design allows the information module 62 to slide synchronously with the operating lever 52 of the locking device 5. When the storage box 22 rotates to the retrieval port 12 and is locked in place, the information module 62 approaches and is recognized by the information reading module 61 at the retrieval port 12. The guidance module 63 then displays the names of the emergency supplies currently in the storage box 22, usage steps, precautions, and other information. This provides intuitive and accurate operational guidance for primary healthcare workers (especially those with limited experience), preventing them from picking up the wrong items or misusing procedures, further standardizing the rescue process, and improving operational accuracy and efficiency. This device is linked to the locking mechanism, requiring no additional triggering, and ensures accurate and timely information transmission, reducing the risk of rescue errors at the primary level. The information module 62 can use an NFC chip or barcode tag; the information reading module 61 can use an NFC reader or barcode scanner; and the guidance module 63 can use an LED display screen or a speaker.
