Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical rescue boxes, in particular to a medical rescue box for high-salt and high-humidity battlefield. BACKGROUND

[0002] In modern military combat scenarios, high-salt and high-humidity environments pose many severe challenges to medical rescue work. The battlefield is often located in coastal areas, marshland, or is affected by special weather conditions, showing high-salt and high-humidity characteristics. The salt and humidity in such a special environment can have a great negative impact on the preservation of medical equipment and drugs.

[0003] High humidity environment is prone to cause rust and corrosion of metal medical devices, affecting their normal use function and service life. For example, the joint parts of surgical instruments may be jammed due to rust, affecting the accuracy and timeliness of surgical operations. For drugs, humid air may cause the drugs to become damp and deteriorate, reducing drug efficacy and even producing harmful substances. The active ingredients of some drugs may undergo hydrolysis, oxidation, and other chemical reactions under high-humidity conditions, thereby losing their therapeutic effect. High-salt environment further exacerbates the risk of corrosion, as salt can accelerate the electrochemical corrosion process of metals, and may also erode the packaging materials of some drugs, damaging the integrity of the packaging and exposing the drugs to harsh environments.

[0004] Traditional medical rescue boxes are designed to be airtight during manufacturing, thus meeting the basic storage and transportation needs in ordinary environments, but they have obvious limitations in high-salt and high-humidity battlefield environments. When opening and taking out items, it is difficult to effectively block the intrusion of salt and moisture. Moreover, it is not possible to intuitively understand whether the airtightness of the rescue box has been compromised. Once the airtightness of the rescue box is compromised, the items inside will be eroded by the high-salt and high-humidity environment, leading to the loss and failure of rescue supplies, and seriously affecting the effectiveness and efficiency of battlefield medical rescue.

[0037] The end surface of the semicircular shell 220 is connected with a mesh plate 230, the mesh plate 230 is connected with the semicircular shell 220 in a clamping or magnetic attraction manner, and the silica gel desiccant in the semicircular shell 220 can be replaced after the mesh plate 230 is removed.

[0038] The structure of the drying mechanism 200 is specifically as follows:

[0039] The drying mechanism 200 further comprises rotating shafts 240 connected to the semicircular shells 220, and the sealing plate 210 is axially slidably connected with a plug rod 270, and the sidewalls of the four rotating shafts 240 located at the four corners of the sealing plate 210 are each provided with a plug hole matched with the plug rod 270, and the other ends of the four rotating shafts 240 are each connected with a torsion spring 250 between the sealing plate 210, when the box body 120 leaks, the plug rod 270 is pulled out of the plug hole, so that the four semicircular shells 220 at the four corners rotate by one hundred and eighty degrees.

[0040] The sealing plate 210 is arranged on the box cover 110, and the space between the box cover 110 and the sealing plate 210 is sealed in the initial state, at this time, the silica gel desiccant in the four semicircular shells 220 at the four corners is in the space between the box cover 110 and the sealing plate 210, preventing the silica gel desiccant in the four semicircular shells 220 at the four corners from being damp, and the end of the rotating shaft 240 of the four semicircular shells 220 at the four corners is connected with a torsion spring 250, the torsion spring 250 provides power for the rotation of the four semicircular shells 220 at the four corners, and the plug rod 270 is inserted into the end of the rotating shaft 240 away from the torsion spring 250, so that the opening of the semicircular shell 220 at this time does not face the box body 120, and when the box body 120 leaks, the plug rod 270 is pulled out of the rotating shaft 240, so that the four semicircular shells 220 at the four corners rotate.

[0041] Regarding the structure of the containing mechanism 100, in particular:

[0042] The containing mechanism 100 further comprises a lifting plate 180, and the lifting plate 180 is connected with a passive air cylinder 170 between the box body 120, the outside of the box body 120 is connected with a rectangular cylinder 130, a rectangular rod 140 is slidably connected in the rectangular cylinder 130 through a first spring 150, the rectangular cylinder 130 is communicated with the passive air cylinder 170 through a first air pipe 160, when the box cover 110 is closed, the box cover 110 presses the rectangular rod 140 to slide downward, so that the rectangular cylinder 130 releases the gas in the passive air cylinder 170 to make the passive air cylinder 170 shorter.

[0043] When the box cover 110 is closed, the box cover 110 pushes the rectangular rod 140, at this time, the rectangular rod 140 moves downward in the rectangular cylinder 130, so that the air in the rectangular cylinder 130 is released into the passive air cylinder 170 through the first air pipe 160, the first air pipe 160 is communicated with the upper space of the piston of the passive air cylinder 170, so that after the gas is injected into the passive air cylinder 170, the passive air cylinder 170 is shortened, at this time, the lifting plate 180 is lowered, providing sufficient space for the articles placed on the lifting plate 180, preventing the articles from being squeezed, when the box cover 110 is opened, the first spring 150 pushes the rectangular rod 140 to move upward, so that the lifting plate 180 moves upward, facilitating the taking and placing of the articles on the lifting plate 180.

[0044] Regarding the structure of the gas releasing mechanism 300, in particular:

[0045] The gas releasing mechanism 300 further comprises a gas storage tank 310, a gas releasing pipe 311 connected to the gas storage tank 310, a valve arranged on the gas releasing pipe 311, a tooth ring 320 connected to a valve rod of the valve, a first gear rack 321 and a second gear rack 322 connected to a lower surface of the lifting plate 180, the first gear rack 321 and the second gear rack 322 being symmetrically arranged on two sides of the valve, and the second gear rack 322 being arranged below the first gear rack 321, so that when the lifting plate 180 moves downward, the second gear rack 322 first engages with the tooth ring 320 to drive the tooth ring 320 to rotate in a forward direction, so that the valve is opened, and then the first gear rack 321 engages with the tooth ring 320 to drive the tooth ring 320 to rotate in a reverse direction, so that the valve is closed.

[0046] The gas storage tank 310 is filled with high-pressure protective gas, or the gas storage tank 310 can be arranged in a form that a high-pressure protective gas tank is placed inside. The gas releasing pipe 311 communicates with the protective gas in the gas storage tank 310, and a valve is arranged on the gas releasing pipe 311. The release of the protective gas is realized by opening and closing the valve. When the box cover 110 is closed, the lifting plate 180 moves downward. At this time, the second gear rack 322 first engages with the tooth ring 320 to drive the tooth ring 320 to rotate in a forward direction, so that the valve is opened, and then the first gear rack 321 engages with the tooth ring 320 to drive the tooth ring 320 to rotate in a reverse direction, so that the valve is closed, realizing the automatic opening and closing of the valve and the automatic release of the protective gas, so as to discharge the salty and humid gas in the box body 120. When the box cover 110 is opened, the lifting plate 180 moves upward. At this time, the first gear rack 321 drives the valve to open, and then the second gear rack 322 drives the valve to close, so that the protective gas is released in the box body 120 again, preventing the salty and humid gas from contacting the articles in the box body 120.

[0047] In an optional mode of the embodiment, the following is preferred:

[0048] A ventilation hole 190 is arranged at an edge of the lifting plate 180.

[0049] The arrangement of the ventilation hole 190 enables the protective gas released at the lower part of the lifting plate 180 to move to the upper part of the lifting plate 180 through the ventilation hole 190, so as to protect the articles on the lifting plate 180.

[0050] In an optional mode of the embodiment, the following is preferred:

[0051] The gas releasing mechanism 300 further comprises a slow-release tank 330 in communication with the gas releasing pipe 311, a sliding plate 350 slidably connected in the slow-release tank 330, a pin rod 360 connected to the sliding plate 350, a tension spring 370 connected between an end of the pin rod 360 and an outer wall of the slow-release tank 330, and a pressure valve 340 arranged on the slow-release tank 330.

[0052] The protective gas released from the gas release pipe 311 first enters the space between the slide plate 350 and the slow-release box 330, and the gas release pushes the slide plate 350 to slide, so that the tension spring 370 is stretched, thereby increasing the pressure in the slow-release box 330, and then the protective gas in the slow-release box 330 is slowly released into the box 120 through the pressure valve 340, avoiding the waste caused by the rapid release of the protective gas and the reduction of the protection effect due to the large amount of escape to the outside of the box 120.

[0053] Regarding the structure of the air tightness detection mechanism 400, in particular:

[0054] The air tightness detection mechanism 400 includes a micro cylinder 450 connected to the outer wall of the slow-release box 330, a cylinder 260 connected to the sealing plate 210, and a plug rod 270 slidingly connected to the cylinder 260. The micro cylinder 450 and the cylinder 260 are connected by a second gas pipe 460. After closing the box cover 110, if the box 120 leaks, the gas in the slow-release box 330 is completely released, so that the end of the pin rod 360 presses the micro cylinder 450, so that the micro cylinder 450 extracts the gas in the cylinder 260, and the plug rod 270 is pulled out of the plug hole.

[0055] The gas in the slow-release box 330 is released slowly. When the box cover 110 is closed, a closed space is formed in the box 120, so that external gas cannot enter the box 120, thereby increasing the internal pressure of the box 120. The gas in the slow-release box 330 is not emptied. If the air tightness of the box 120 leaks, a high-pressure environment will not be formed in the box 120, so that the gas in the slow-release box 330 will continue to be released until it is emptied, so that the end of the pin rod 360 pushes the micro cylinder 450 to shorten. At this time, the micro cylinder 450 extracts air in the cylinder 260 through the second gas pipe 460, so that the plug rod 270 moves away from the shaft 240, and the semicircular shell 220 on the four corners can rotate under the action of the torsional spring 250.

[0056] In an optional manner of the embodiment, it is more preferred that:

[0057] Two limiting rings 280 are symmetrically arranged in the cylinder 260, and the second gas pipe 460 communicates with the space between the two limiting rings 280 in the cylinder 260.

[0058] Two cylinders 260 are provided, and the two cylinders 260 are symmetrically arranged to control the rotation locking of the two shafts 240 on one side. After the second gas pipe 460 extracts air in the cylinder 260, the two plug rods 270 move close to each other, thereby pulling out the plug slots on the shafts 240. When one of the plug rods 270 contacts the limiting ring 280, the other continues to move close to the limiting ring 280, so that both plug rods 270 can pull out the plug slots on the corresponding shafts 240.

[0059] In an alternative mode of the embodiment, the following is preferred:

[0060] The airtightness detection mechanism 400 further comprises a control box 410, which is connected to the second air pipe 460, and a sliding block 420 is slidingly connected in the control box 410, and a gas guide hole 421 is formed in the sliding block 420, when the box cover 110 is opened, the sliding block 420 moves upward in the control box 410, so that the gas guide hole 421 is not communicated with the second air pipe 460, and when the box cover 110 is closed, the sliding block 420 moves downward in the control box 410, so that the gas guide hole 421 is communicated with the second air pipe 460.

[0061] When the box cover 110 is opened, the box body 120 is in an open state, so that the gas in the relief box 330 can be exhausted, in this state, the sliding block 420 in the control box 410 moves upward, so that the gas guide hole 421 is not communicated with the second air pipe 460, so that the sliding of the sliding plate 350 does not push the pin rod 360 to shorten the micro pneumatic cylinder 450, thereby avoiding the rotation of the four semi-circular shells 220 at the four corners of the sealing plate 210 in this state, and when the box cover 110 is closed, the sliding block 420 moves downward, so that the gas guide hole 421 is communicated with the second air pipe 460, so that if the box body 120 leaks in airtightness, the four semi-circular shells 220 at the four corners of the sealing plate 210 can be driven to rotate subsequently.

[0062] In an alternative mode of the embodiment, the following is preferred:

[0063] The top of the sliding block 420 is connected with a rectangular plate 430, and the second spring 440 is connected between the rectangular plate 430 and the control box 410, and the lower surface of the lifting plate 180 is connected with a pressing block 470, when the box cover 110 is closed to move the lifting plate 180 downward, the pressing block 470 moves downward and presses the sliding block 420, so that the gas guide hole 421 is communicated with the second air pipe 460.

[0064] The lifting plate 180 rises and falls with the opening and closing of the box cover 110, when the box cover 110 is opened, the pressing block 470 connected to the lifting plate 180 is away from the sliding block 420, at this time the second spring 440 lifts the sliding block 420, so that the second air pipe 460 is not communicated, and after the box cover 110 is closed, the pressing block 470 presses the sliding block 420 to move downward, so that the second air pipe 460 is unobstructed.

[0065] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
