Description

Technical Field

[0001] The invention relates to the technical field of medical rescue boxes, in particular to a medical rescue box for high-salt and high-humidity battlefields. Background Art

[0002] In modern military combat scenarios, high-salt and high-humidity environments pose many severe challenges to medical rescue work. Battlefields are often located in coastal areas, swamps, or experience special climatic conditions, showing the characteristics of high salt and high humidity. The salt and humidity in this special environment will have a great negative impact on the preservation of medical equipment and drugs.

[0003] High humidity environments can easily cause metal medical devices to rust and corrode, affecting their normal functions and service life. For example, the joints of surgical instruments may become stuck due to rust, affecting the accuracy and timeliness of surgical operations. For medicines, humid air may cause them to become damp and deteriorate, reducing their efficacy and even producing harmful substances. The active ingredients of some medicines may undergo chemical reactions such as hydrolysis and oxidation under high humidity conditions, thereby losing their therapeutic effects. High-salt environments further increase the risk of corrosion. Salt accelerates the electrochemical corrosion process of metals, and may also corrode the packaging materials of some medicines, destroying the integrity of the packaging and exposing the medicines to harsh environments.

[0004] Traditional medical rescue boxes are manufactured to ensure air tightness, so that they can meet basic storage and transportation needs in ordinary environments, but they have obvious limitations in high-salt and high-humidity battlefield environments. When opening to take out items, it is difficult to effectively prevent the invasion of salt and water vapor. And it is impossible to intuitively understand whether the rescue box has an airtight leak. Once the airtightness of the rescue box is damaged, the items in the box will be corroded by the high-salt and high-humidity environment, resulting in the loss and failure of rescue materials, seriously affecting the effectiveness and efficiency of battlefield medical rescue. Summary of the invention

[0005] The invention provides a medical rescue box for a high-salt and high-humidity battlefield, so as to solve the problem that the existing rescue box is inconvenient to be used in a high-salt and high-humidity environment.

[0006] In order to alleviate the above technical problems, the technical solution provided by the present invention is:

[0007] A medical rescue box for a high-salt and high-humidity battlefield, comprising a containing mechanism and a drying mechanism, wherein the containing mechanism comprises a box body and a box cover hinged to the box body, and the drying mechanism comprises a sealing plate connected to the box cover, wherein the middle part of the sealing plate and near the four corners are rotatably connected with five semicircular shells with built-in silica gel desiccant, the opening of the semicircular shell in the middle part faces the box body, and the openings of the semicircular shells at the four corners face the box cover;

[0008] A gas release mechanism is arranged in the box body, and the gas release mechanism releases protective gas into the box body. Sealing strips are arranged on the box cover and the box body. After the box cover is closed, if gas leaks into the box body, the semicircular shells at the four corners rotate and the openings are all facing the box body.

[0009] Furthermore, the drying mechanism also includes a rotating shaft connected to the semicircular shell, an insertion rod is axially slidably connected to the sealing plate, and the side walls of the four rotating shafts located at the four corners of the sealing plate are provided with insertion holes that cooperate with the insertion rod. The other ends of the four rotating shafts are connected to the sealing plate with torsion springs. When the box body leaks, the insertion rod is pulled out of the insertion hole, so that the four semicircular shells at the four corners rotate one hundred and eighty degrees.

[0010] Furthermore, the accommodating mechanism also includes a lifting plate, a passive cylinder is connected between the lifting plate and the box body, a rectangular tube is connected to the outside of the box body, a rectangular rod is slidably connected to the inside of the rectangular tube through a first spring, a first air pipe is connected between the rectangular tube and the passive cylinder, and when the box cover is closed, the box cover presses the rectangular rod to slide down, so that the rectangular tube releases gas into the passive cylinder to shorten the passive cylinder.

[0011] Furthermore, the gas release mechanism also includes a gas storage box, which is connected to a gas release pipe, and a valve is arranged on the gas release pipe. A gear ring is connected to the valve stem of the valve, and a first rack and a second rack are connected to the lower surface of the lifting plate. The first rack and the second rack are symmetrically arranged on both sides of the valve, and the second rack is located at the lower part of the first rack, so that when the lifting plate moves downward, the second rack first engages with the gear ring to drive the gear ring to rotate forward, thereby opening the valve, and the first rack then engages with the gear ring to drive the gear ring to reverse, thereby closing the valve.

[0012] Furthermore, ventilation holes are provided at the edge of the lifting plate.

[0013] Furthermore, the gas release mechanism also includes a slow-release box connected to the gas release pipe, a slide is slidably connected inside the slow-release box, a pin is connected to the slide, a tension spring is connected between the end of the pin and the outer wall of the slow-release box, and a pressure valve is provided on the slow-release box.

[0014] Furthermore, it also includes an air-tightness detection mechanism, which includes a micro-cylinder connected to the outer wall of the slow-release box, a cylinder connected to the sealing plate, the insertion rod slidably connected to the cylinder, and a second air pipe is connected between the micro-cylinder and the cylinder. After closing the box cover, if the box body leaks, the gas in the slow-release box is completely released, so that the end of the pin rod presses the micro-cylinder, so that the micro-cylinder extracts the gas in the cylinder, so that the insertion rod is pulled out of the socket.

[0015] Furthermore, two limiting rings are symmetrically arranged in the cylinder, and the second air pipe is connected to the space between the two limiting rings in the cylinder.

[0016] Furthermore, the air tightness detection mechanism also includes a control box, which is connected to the second air pipe. A slider is slidably connected inside the control box, and an air guide hole is opened on the slider. When the box cover is opened, the slider moves up to the control box, so that the air guide hole is not connected to the second air pipe, and when the box cover is closed, the slider moves down to the control box, so that the air guide hole is connected to the second air pipe.

[0017] Furthermore, a rectangular plate is connected to the top of the slider, a second spring is connected between the rectangular plate and the control box, a pressure block is connected to the lower surface of the lifting plate, and when the box cover is closed to move the lifting plate downward, the pressure block moves downward and presses the slider to connect the air guide hole with the second air pipe.

[0018] The beneficial effects of the present invention are analyzed as follows:

[0019] A medical rescue box for battlefields with high salt and humidity comprises a containing mechanism and a drying mechanism. The containing mechanism comprises a box body and a box cover hinged to the box body. The drying mechanism comprises a sealing plate connected to the box cover. Five semicircular shells with built-in silica gel desiccants are rotatably connected to the middle part and near the four corners of the sealing plate. The opening of the semicircular shell in the middle faces the box body, and the openings of the semicircular shells at the four corners face the box cover. A gas release mechanism is arranged in the box body, and the gas release mechanism releases protective gas into the box body. Sealing strips are arranged on the box cover and the box body. After the box cover is closed, if gas leaks into the box body, the semicircular shells at the four corners rotate and their openings all face the box body.

[0020] Medical equipment or medicines are placed in a box, and the contact surfaces of the box cover and the box are provided with sealing strips. After the box cover is closed, the box can form a sealed space, thereby isolating the high-salt and high-humidity environment and reducing the influence of the internal items on the external environment. When the box cover is closed, the gas release mechanism releases protective gas into the box. This protective gas can be an inert gas, or carbon dioxide, etc., and the protective gas can be released from a small pressure tank placed in the box. When the protective gas is released, it can occupy the internal space of the box and drive the salt-containing humid gas out of the box, so that after the box cover is closed, the salt-containing humid air in the internal space of the box is driven out in large quantities. In addition, the silica gel desiccant in the semicircular shell can dry the air in the space inside the box. If an airtight leak occurs in the box, the four semicircular shells at the four corners of the sealing plate will flip 180 degrees, so that the silica gel desiccant in the four semicircular shells at the four corners can dehumidify the internal space of the box. At this time, the storage time of medicines and other items in the box after the airtight leak can be extended. Moreover, after opening the box cover later, if it is found that the semicircular shells at the four corners have rotated and the silica gel desiccant has changed from blue to pink, it means that the silica gel dryer is saturated with moisture. At this time, the medicines in the box may have been contaminated and cannot be used. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Examples, such as Figure 1-Figure 7As shown, a medical rescue box for a high-salt and high-humidity battlefield includes a containing mechanism 100 and a drying mechanism 200. The containing mechanism 100 includes a box body 120 and a box cover 110 hinged to the box body 120. The drying mechanism 200 includes a sealing plate 210 connected to the box cover 110. Five semicircular shells 220 with built-in silica gel desiccant are rotatably connected to the middle part of the sealing plate 210 and near the four corners. The opening of the semicircular shell 220 in the middle is toward the box body 120, and the openings of the semicircular shells 220 at the four corners are toward the box cover 110. A gas release mechanism 300 is arranged in the box body 120, and the gas release mechanism 300 releases protective gas into the box body 120. Sealing strips are arranged on the box cover 110 and the box body 120. After closing the box cover 110, if gas leaks into the box body 120, the semicircular shells 220 at the four corners will rotate and their openings will all face the box body 120.

[0035] The working mechanism of the medical rescue box provided in this embodiment is as follows:

[0036] When in use, medical equipment or medicines are placed in the box body 120, and the contact surfaces of the box cover 110 and the box body 120 are both provided with sealing strips. After the box cover 110 is closed, the box body 120 can form a sealed space, thereby isolating the high-salt and high-humidity environment and reducing the influence of the internal items on the external environment. When the box cover 110 is closed, the gas release mechanism 300 releases protective gas into the box body 120. This protective gas can be an inert gas, or carbon dioxide, etc., and the protective gas can be released from a small pressure tank placed in the box body 120. When the protective gas is released, it can occupy the internal space of the box body 120 and drive the salt-containing humid gas out of the box body 120, so that the salt-containing humid air in the internal space of the box body 120 is In addition, the silica gel desiccant in the semicircular shell 220 can dry the air in the space in the box 120. If the box 120 leaks air tightness, the four semicircular shells 220 at the four corners of the sealing plate 210 will turn 180 degrees, so that the silica gel desiccant in the four semicircular shells 220 at the four corners can dehumidify the internal space of the box 120. At this time, the storage time of medicines and other items in the box 120 after the air tightness leak can be extended. Moreover, after the box cover 110 is opened later, if it is found that the semicircular shells 220 at the four corners have rotated and the silica gel desiccant changes from blue to pink, it means that the silica gel dryer has been saturated with moisture. At this time, the medicines in the box 120 may have been contaminated and cannot be used.

[0037] The end surface of the semicircular shell 220 is connected with a mesh plate 230 , which is connected to the semicircular shell 220 by means of snap connection or magnetic attraction. After the mesh plate 230 is removed, the silica gel desiccant in the semicircular shell 220 can be replaced.

[0038] Regarding the structure of the drying mechanism 200, specifically:

[0039] The drying mechanism 200 also includes a rotating shaft 240 connected to the semicircular shell 220, and an insertion rod 270 is axially slidably connected to the sealing plate 210. The side walls of the four rotating shafts 240 located at the four corners of the sealing plate 210 are provided with holes that cooperate with the insertion rod 270. The other ends of the four rotating shafts 240 are connected to the sealing plate 210 with torsion springs 250. When the box body 120 leaks, the insertion rod 270 is pulled out of the hole, so that the four semicircular shells 220 at the four corners rotate 180 degrees.

[0040] The sealing plate 210 is arranged on the box cover 110. In the initial state, the space between the box cover 110 and the sealing plate 210 is sealed. 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, so as to prevent the silica gel desiccant in the four semicircular shells 220 from getting damp, and the ends of the rotating shafts 240 of the four semicircular shells 220 are connected with torsion springs 250, which provide power for the rotation of the semicircular shells 220 at the four corners. The insertion rod 270 is inserted at one end of the rotating shaft 240 away from the torsion spring 250, so that the opening of the semicircular shell 220 at this time is not facing the box body 120, and when the box body 120 leaks, the insertion rod 270 pulls out the rotating shaft 240 to make the semicircular shells 220 at the four corners rotate.

[0041] Regarding the structure of the accommodation mechanism 100, specifically:

[0042] The accommodating mechanism 100 also includes a lifting plate 180, a passive cylinder 170 is connected between the lifting plate 180 and the box body 120, a rectangular tube 130 is connected to the outside of the box body 120, a rectangular rod 140 is slidably connected inside the rectangular tube 130 via a first spring 150, a first air pipe 160 is connected between the rectangular tube 130 and the passive cylinder 170, when the box cover 110 is closed, the box cover 110 presses the rectangular rod 140 to slide down, so that the rectangular tube 130 releases gas into the passive cylinder 170 to shorten the passive cylinder 170.

[0043] When the box cover 110 is closed, the box cover 110 pushes the rectangular rod 140, and at this time the rectangular rod 140 moves downward in the rectangular tube 130, so that the air in the rectangular tube 130 is released into the passive cylinder 170 through the first air pipe 160. The first air pipe 160 is connected to the upper space of the piston of the passive cylinder 170, so that after the gas is injected into the passive cylinder 170, the passive cylinder 170 shortens, and at this time the lifting plate 180 descends, providing sufficient space for the items placed on the lifting plate 180 to prevent the items from being squeezed. When the box cover 110 is opened, the first spring 150 pushes the rectangular rod 140 to move upward, thereby moving the lifting plate 180 upward, making it easy to take and place the items on the lifting plate 180.

[0044] Regarding the structure of the gas release mechanism 300, specifically:

[0045] The gas release mechanism 300 also includes a gas storage box 310, which is connected to a gas release pipe 311. A valve is arranged on the gas release pipe 311. A gear ring 320 is connected to the valve stem of the valve. A first rack 321 and a second rack 322 are connected to the lower surface of the lifting plate 180. The first rack 321 and the second rack 322 are symmetrically arranged on both sides of the valve, and the second rack 322 is located at the lower part of the first rack 321. Therefore, when the lifting plate 180 moves downward, the second rack 322 first engages with the gear ring 320 to drive the gear ring 320 to rotate forward, thereby opening the valve, and the first rack 321 then engages with the gear ring 320 to drive the gear ring 320 to reverse, thereby closing the valve.

[0046] The gas storage box 310 is filled with high-pressure protective gas, or the gas storage box 310 can also be configured to have a high-pressure protective gas tank placed inside. The gas release pipe 311 is connected to the protective gas in the gas storage box 310. A valve is set on the gas release pipe 311, and the protective gas is released by opening and closing the valve. When the box cover 110 is closed, the lifting plate 180 moves down. At this time, the second rack 322 first engages with the gear ring 320 to drive the gear ring 320 to rotate forward, thereby opening the valve. The first rack 321 then engages with the gear ring 320 to drive the gear ring 320 to reverse, thereby closing the valve, realizing automatic opening and closing of the valve, automatically releasing the protective gas, and discharging the salt-containing humid gas in the box body 120. When the box cover 110 is opened, the lifting plate 180 moves up. At this time, the first rack 321 drives the valve to open, and then the second rack 322 drives the valve to close, so that the protective gas is released into the box body 120 again, preventing the salt-containing humid gas from contacting the objects in the box body 120.

[0047] Among the optional methods of this embodiment, the more preferred ones are:

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

[0049] The provision of the air holes 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 air holes 190 to protect the items on the lifting plate 180 .

[0050] Among the optional methods of this embodiment, the more preferred ones are:

[0051] The gas release mechanism 300 also includes a slow-release box 330 connected to the gas release pipe 311, a slide plate 350 is slidably connected inside the slow-release box 330, a pin rod 360 is connected to the slide plate 350, a tension spring 370 is connected between the end of the pin rod 360 and the outer wall of the slow-release box 330, and a pressure valve 340 is arranged on the slow-release box 330.

[0052] The protective gas released from the gas release pipe 311 first enters the space between the slide plate 350 and the release box 330. When the gas is released, the slide plate 350 is pushed to slide, so that the tension spring 370 is stretched, thereby increasing the pressure in the release box 330. Then, the protective gas in the release box 330 is slowly released into the box body 120 through the pressure valve 340, avoiding the rapid release of the protective gas that causes a large amount of gas to escape into the external space of the box body 120, causing waste and reducing the protective effect.

[0053] Regarding the structure of the airtightness detection mechanism 400, specifically:

[0054] The airtightness detection mechanism 400 includes a micro cylinder 450 connected to the outer wall of the slow-release box 330, a cylinder 260 is connected to the sealing plate 210, and the insertion rod 270 is slidably connected to the cylinder 260. A second air pipe 460 is connected between the micro cylinder 450 and the cylinder 260. After closing the box cover 110, if the box body 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, so that the insertion rod 270 is pulled out of the socket.

[0055] The gas in the slow-release box 330 is released relatively slowly. When the box cover 110 is closed, a closed space is formed in the box body 120. At this time, external gas will not enter the box body 120, so that the internal pressure of the box body 120 increases, and the gas in the slow-release box 330 will not be emptied. If an airtight leak occurs in the box body 120, a high-pressure environment will not be formed in the box body 120, so that the gas in the slow-release box 330 will continue to be released until it is emptied. At this time, the end of the pin rod 360 pushes the micro cylinder 450 to shorten. At this time, the micro cylinder 450 draws air in the cylinder 260 through the second air pipe 460, so that the insertion rod 270 is away from the rotating shaft 240, so that the semicircular shells 220 at the four corners can rotate under the action of the torsion spring 250.

[0056] Among the optional methods of this embodiment, the more preferred ones are:

[0057] Two limiting rings 280 are symmetrically arranged in the cylinder 260 , and the second air pipe 460 is connected to the space between the two limiting rings 280 in the cylinder 260 .

[0058] There are two cylinders 260, which are symmetrically arranged to control the rotation locking of the two rotating shafts 240 on one side respectively. After the second air pipe 460 draws the air in the cylinder 260, the two insertion rods 270 approach each other, thereby pulling out the slots on the rotating shaft 240. When one of the insertion rods 270 contacts the limiting ring 280, the other continues to move toward the adjacent limiting ring 280, ensuring that the two insertion rods 270 can be pulled out of the slots on the corresponding rotating shaft 240.

[0059] Among the optional methods of this embodiment, the more preferred ones are:

[0060] The airtightness detection mechanism 400 also includes a control box 410, which is connected to the second air pipe 460. A slider 420 is slidably connected inside the control box 410, and an air guide hole 421 is opened on the slider 420. When the box cover 110 is opened, the slider 420 moves up to the control box 410, so that the air guide hole 421 is not connected to the second air pipe 460; and when the box cover 110 is closed, the slider 420 moves down to the control box 410, so that the air guide hole 421 is connected to 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 slow-release box 330 can be emptied. In this state, the slider 420 in the control box 410 moves up, so that the air guide hole 421 is not connected to the second air pipe 460, so that the sliding of the slide plate 350 at this time will not cause the pin rod 360 to push the micro cylinder 450 to shorten, thereby avoiding the rotation of the four semicircular shells 220 at the four corners of the sealing plate 210 in this state. When the box cover 110 is closed, the slider 420 moves down, so that the air guide hole 421 is connected to the second air pipe 460, so that at this time, if the air tightness of the box body 120 leaks, the four semicircular shells 220 at the four corners of the sealing plate 210 can be driven to rotate subsequently.

[0062] Among the optional methods of this embodiment, the more preferred ones are:

[0063] A rectangular plate 430 is connected to the top of the slider 420, a second spring 440 is connected between the rectangular plate 430 and the control box 410, a pressure block 470 is connected to the lower surface of the lifting plate 180, and when the box cover 110 is closed to move the lifting plate 180 downward, the pressure block 470 moves downward and presses the slider 420 to connect the air guide hole 421 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 moves away from the slider 420. At this time, the second spring 440 lifts the slider 420, so that the second air pipe 460 is blocked. After the box cover 110 is closed, the pressing block 470 presses the slider 420 downward, and 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 invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
