Description

Technical Field

[0002] Medical evacuation refers to the activity of transporting the wounded and sick from the front line to the rear medical institutions according to regulations during wartime for hierarchical treatment. Medical evacuation is a process of treating during evacuation and improving treatment during evacuation. The main contents of the medical work for the wounded and sick are: rescuing the wounded on the front line or at the scene, minimizing battlefield deaths; giving priority to rescuing critically injured patients and striving to reduce the death of the wounded; focusing on preventing and treating wound infections and performing debridement surgeries in a timely manner; treating lightly injured patients at different levels and replenishing the troops in a timely manner after recovery; actively preventing and treating diseases and reducing non-combat casualties; organizing specialized treatments to strive for good treatment effects. In emergency situations, the probability of suffering from surgical injuries to the eyes is extremely high. Therefore, the number of patients evacuated due to eye injuries is relatively large and the situation is very critical. Among them, penetrating eye injuries with intraocular foreign bodies are a serious type of eye injury, especially the retention of copper foreign bodies, which is very harmful to the eyeball. However, the existing protection devices generally can only be applied to general wards and ambulances for transfer. For patients who need air transportation, they neither meet the conditions for use on airline seats nor can they adapt to the vibration and high-noise environment during air transportation for patients. Therefore, there is a need for a monitoring and protection device for air transportation medical evacuation of eye injuries that can assist medical staff in transporting patients by air to solve the above problems.

Specific embodiments

[0032] The following combines the attached Figures 1 - 8 Make a further detailed description of the specific embodiments of the present invention

[0033] Example 1, consisting of Figures 1 - 8Given that the present invention includes a fixed pad 1, in order to achieve the purpose of helping patients for protection during air medical evacuation, a rotatable arc-shaped frame 2 is provided at the rear side of the fixed pad 1. Two vertical plates 3 are fixedly connected to the rear side of the arc-shaped frame 2. An arc-shaped plate 4 is fixedly connected to the middle of each vertical plate 3. A movable connecting frame 5 is provided on the side of each vertical plate 3 away from the corresponding arc-shaped plate 4. A transverse plate 6 is provided at the rear side of the arc-shaped frame 2. The left and right sides of the transverse plate 6 are respectively fixedly connected to the corresponding connecting frames 5. A movable wetting frame 7 is provided at the rear side of the connecting frame 5. An eyelid-opening mechanism 8 is provided at the rear side of the transverse plate 6. The eyelid-opening mechanism 8 and the wetting frame 7 cooperate with each other to form a structure for protecting the patient's eyes. A movable cold compress frame 9 is provided on the side of each connecting frame 5 close to the corresponding vertical plate 3. The cold compress frame 9 and the arc-shaped plate 4 cooperate with each other to form a structure for reducing swelling during the patient's air evacuation protection. A protective bag 10 is fixedly connected to the inner side of each arc-shaped plate 4. A sound insulation pad 11 is fixedly connected to the inner side of each protective bag 10;

[0034] During use, the arc-shaped frame 2 can be first placed at the position of the patient's posterior brain, and then the patient's cheeks are clamped by the arc-shaped plate 4 and the protective bag 10. At this time, the sound insulation pad 11 is located at the position of the patient's ears. The sound insulation pad 11 and the protective bag 10 cooperate with each other, which can not only fix the patient's head, but also the sound insulation pad 11 can reduce the noise received by the patient during air evacuation, reducing the harm to the patient during air evacuation. Then, the injured eyelid of the patient is opened through the eyelid-opening mechanism 8, reducing the risk of secondary downward pressure on the foreign body inside the eye after the patient's eyelid is closed. Then, after the transverse plate 6 is moved to a suitable position, the eyelid-opening mechanism 8 is fixed to the transverse plate 6. At this time, the wetting frame 7 starts intermittent movement to squeeze the medicine liquid, continuously wetting and relieving pain for the patient's opened eyes. At the same time, the cold compress frame 9 will move up and down in a cycle, and the patient's face is cold-compressed and swollen through the cold compress ball 65.

[0035] Embodiment 2, on the basis of Embodiment 1, Figures 1 - 8 Given that in order to achieve the purpose of being able to adapt to the situation that patients are not easily transported lying flat during air evacuation, a neck airbag 12 is fixedly connected to the rear side of the fixed pad 1. A movable first fixing frame 13 is provided on the upper side of the fixed pad 1. A fixed threaded rod 14 is rotatably connected to the middle of the first fixing frame 13. The lower side of the fixed threaded rod 14 is threadedly connected to the fixed pad 1. A first fixing plate 15 is slidably connected to the front side of the first fixing frame 13. A plurality of first tension springs 16 are fixedly connected to the rear side of the first fixing plate 15. The rear side of each first tension spring 16 is fixedly connected to the first fixing frame 13. The first fixing plate 15, the first fixing frame 13 and the first tension springs 16 cooperate with each other to form a structure for fixing the position of the fixed pad 1;

[0036] When in use, the neck of the patient can be supported by inflating the neck airbag 12. When the patient is transported in a horizontal (lying flat) state, the fixing pad 1 can be fixed to the end of the patient's hospital bed through the first fixing plate 15, the first fixing frame 13 and the fixing threaded rod 14. When the patient is in a sitting and transporting state, the first fixing plate 15, the first fixing frame 13 and the fixing threaded rod 14 can be fixed to the backrest of the patient's seat, and the fixing pad 1 can still be fixed.

[0037] Embodiment 3, on the basis of Embodiment 2, is Figures 1 - 8 given. In order to achieve the purpose of reducing the vibration of the patient's wound during air transportation, a plurality of rotating grooves 17 are formed in the rear side of the fixing pad 1. A plurality of rotating wheels 18 are rotatably connected to the front side of the arc-shaped frame 2. The rotating wheels 18 and the rotating grooves 17 cooperate with each other to form a structure for protecting the rotation of the patient's head. A detachable head soft pad 19 is provided on the rear side of the arc-shaped frame 2. The head soft pad 19 is made of sponge and is detachably connected to the arc-shaped frame 2 through snap fasteners. A pressing bladder 20 is fixedly connected to the front side of the arc-shaped frame 2. An inflation bladder 21 is fixedly connected to the inside of the pressing bladder 20. The right side of the inflation bladder 21 is communicated with a hand-squeezed air bladder ball 22. The hand-squeezed air bladder ball 22 is a prior art and will not be described in detail here. Each of the protection bladders 10 is communicated with the pressing bladder 20.

[0038] When in use, the arc-shaped plates 4 can be respectively placed on both sides of the patient's face. The arc-shaped plates 4 are deformed under the action of the first springs 23 to fit the patient's face. Then, the inflation bladder 21 can be inflated by squeezing the hand-squeezed air bladder ball 22. After the inflation bladder 21 expands in the pressing bladder 20, the liquid in the pressing bladder 20 enters the protection bladders 10, so that the protection bladders 10 can be close to the patient's face and fix the patient's face more closely. When the patient is impacted or vibrated during transportation, since the fixing pad 1 and the arc-shaped frame 2 are slidably connected through the rotating wheels 18, the vibration and even impact during transportation can be effectively absorbed.

[0039] Embodiment 4, on the basis of Embodiment 3, is Figures 1 - 8Given that, in order to achieve the purpose of reducing secondary damage to the patient's wound during transportation, the eyelid opening mechanism 8 includes a first rotating frame 801.

[0040] During use, the patient's eyelids can be opened by the first rotating frame 801 and the second rotating frame 802. Then, after the magnetic limiting block 805 and the magnetic block 806 are attracted, the magnetic limiting block 805 and the limiting disc 803 cooperate with each other to fix the angle between the first rotating frame 801 and the second rotating frame 802, reducing the risk of secondary downward pressure on the foreign body inside the eye after the patient's eyelids are closed.

[0041] Embodiment 5, on the basis of Embodiment 4, Figures 1 - 8 Given that, in order to achieve the purpose of continuously moistening and relieving pain in the patient's eyes, a first moistening tube 24 is fixedly connected to both the first rotating frame 801 and the second rotating frame 802.

The fixed pipe 28 is filled with electrorheological fluid. Electrorheological fluid is a prior art and will not be described in detail here;

[0042] During use, after the eyelid opening mechanism 8 is used to open the patient's eyelids, the connecting frame 5 can be moved to an appropriate position and then the electromagnetic switch 29 is turned on. At this time, the electrorheological fluid in the fixed pipeline 28 becomes solid under the action of the electric field, and the eyelid opening mechanism 8 is fixed. Then, the liquid medicine in the wetting syringe 26 will intermittently pass through the second wetting tube 25 and the first wetting tube 24 into the patient's eye, continuously nursing and treating the patient's eye.

[0043] Embodiment 6, on the basis of Embodiment 5, is given by Figures 1 - 8 In order to achieve the purpose of facilitating the replacement of the liquid medicine for wetting the patient's eyes, a rotatable power disk 30 is provided inside the transverse plate 6.

Upper and lower sides of the semi-circular plate 40 are fixedly connected with an elastic plate 41 respectively.

[0044] During use, when the power disk 30 rotates, due to the cooperation between the intermittent motion blocks 33 and the intermittent motion groove 31, the intermittent motion frame 32 can intermittently rotate, thereby driving the first worm 37 and the first worm gear 38 to rotate through the first driving disk 34, the first transmission belt 36, and the first driven disk 35, so as to drive the wetting threaded rod 39 to rotate, push the wetting frame 7 to move rightward, and then push the wetting syringe 26. When the liquid medicine needs to be replaced, the wetting frame 7 can be pulled backward. At this time, under the action of the elastic plate 41, the semi-circular plate 40 is disengaged from the wetting threaded rod 39, and the wetting frame 7 can be moved to replace or add medicine to the wetting syringe 26.

[0046] During use, after starting the small motor 47, the corresponding large bevel gear 45 is driven to rotate through the driving pinion 48 and the driving gear 49, so as to drive the second driving disc 42 to rotate through the corresponding second driven disc 44, and then the power disc 30 rotates. At the same time, each large bevel gear 45 and the small bevel gear 46 also rotate under the drive of the second driven disc 44.

[0047] Embodiment Eight, on the basis of Embodiment Seven, Figures 1 - 8 Given that in order to achieve the purpose of automatically and reciprocally applying cold compress to the face of a patient, a rotatable second worm 50 is arranged inside each connecting frame 5. A second worm wheel 51 is meshed with the front side of each second worm 50. A fixed sprocket 52 is fixedly connected to each second worm wheel 51. A movable driving sprocket 53 is arranged above each fixed sprocket 52. A movable driven sprocket 54 is arranged above each driving sprocket 53. A chain 55 is engaged with the outside of each driving sprocket 53. A movable driving block 56 is arranged inside each connecting frame 5. Each driving block 56 is rotatably connected to the corresponding driving sprocket 53. Each driving block 56 is threadedly connected to an active control knob 57. A movable driven block 58 is arranged inside each connecting frame 5. Each driven block 58 is rotatably connected to the corresponding driven sprocket 54. A second spring 59 is arranged below each driven block 58;

[0048] During use, the rotation of the second worm 50 drives the rotation of the second worm wheel 51, so that the fixed sprocket 52 drives the driving sprocket 53 and the driven sprocket 54 to rotate through the chain 55. When needed, the position of the driving sprocket 53 can be adjusted by rotating the active control knob 57. Since the total length of the chain 55 is fixed, the driven sprocket 54 moves under the pulling of the driven block 58 and the chain 55. The second spring 59 can keep the driven sprocket 54 tightly pulling the chain 55 all the time, reducing the risk of the chain 55 falling off during use.

[0049] Embodiment IX. On the basis of Embodiment VIII, it is given by Figures 1 - 8 For the purpose of being able to adapt to the facial contour of the patient for cold compress, a connecting sleeve 60 is rotatably connected to each of the chains 55. Each cold compress frame 9 is slidably connected to the corresponding vertical plate 3. The right side of each cold compress frame 9 is slidably connected to the connecting sleeve 60. Each cold compress frame 9 is fixedly connected with a first telescopic rod 61. A second telescopic rod 62 is slidably connected to one side of each first telescopic rod 61 away from the cold compress frame 9. A guiding groove 63 is formed at the rear side of each arc-shaped plate 4. Each second telescopic rod 62 is slidably connected to the guiding groove 63. A elastic block 64 is fixedly connected to one side of each second telescopic rod 62 away from the corresponding first telescopic rod 61. A cold compress ball 65 is detachably connected to the other end of each elastic block. The end of the elastic block 64 close to the cold compress ball 65 is cylindrical and is detachably connected to the cold compress ball 65 through threads, which is convenient for freezing and replacing the cold compress ball 65;

[0050] During use, with the movement of the chain 55, the connecting sleeve 60 is driven to rotate along with the chain 55, and then the cold compress frame 9 is driven to move up and down. During the up and down movement of the cold compress frame 9, the cold compress ball 65 is driven to move up and down through the first telescopic rod 61 and the second telescopic rod 62. Since the second telescopic rod 62 and the guiding groove 63 cooperate with each other, and the guiding groove 63 adapts to the facial contour of the patient under the deformation of the arc-shaped plate 4, the cold compress ball 65 can also fit the facial contour of the patient to perform cold compress on the patient's face.

[0051] Embodiment X. On the basis of Embodiment IX, it is given by Figures 1 - 8Given for a better purpose, a first long shaft 66 is fixedly sleeved inside each of the second worm gears 50. A first bevel gear 67 is fixedly connected to the lower side of each first long shaft 66. A second bevel gear 68 is meshed with the lower side of each first bevel gear 67. Each second bevel gear 68 is fixedly connected to a third driving disc 69. A third transmission belt 70 is fitted to the outside of each third driving disc 69. A third driven disc 71 is fitted to the front side of each third driving disc 69 through the third transmission belt 70. A fixing screw block 72 is threadedly connected to the inside of each connecting frame 5. A twisting block 73 is slidably connected to the middle of each fixing screw block 72. A torsion spring 74 is sleeved on the outside of each twisting block 73. A rotatable first clutch disc 75 and a rotatable second clutch disc 76 are provided inside each connecting frame 5. A viscous liquid is provided between the first clutch disc 75 and the second clutch disc 76. When the second clutch disc 76 is forced to rotate, it will drive the first clutch disc 75 to rotate under the action of the viscous liquid. Each first clutch disc 75 is fixedly connected to the corresponding twisting block 73. Each second clutch disc 76 is fixedly connected to the corresponding third driven disc 71. A third bevel gear 77 is fixedly connected to the upper side of each first long shaft 66. A fourth bevel gear 78 is meshed with the upper side of each third bevel gear 77. Each fourth bevel gear 78 is fixedly connected to a second long shaft 79. Two third long shafts 80 are provided inside the transverse plate 6. A universal coupling 81 is fixedly connected to the side of each third long shaft 80 close to the second long shaft 79. Each small bevel gear 46 is fixedly connected to the corresponding third long shaft 80;

[0052] During use, when each small bevel gear 46 rotates, it drives the second long shaft 79 to rotate through the third long shaft 80 and the universal coupling 81, and then drives the first long shaft 66 to rotate through the fourth bevel gear 78 and the third bevel gear 77. The first long shaft 66 drives the second worm gear 50 to rotate together. At the same time, the first long shaft 66 drives the third driving disc 69 to rotate through the first bevel gear 67 and the second bevel gear 68, so that the third driven disc 71 drives the second clutch disc 76 to rotate. Under the action of the viscous liquid, the first clutch disc 75 rotates together with the second clutch disc 76, and then drives the twisting block 73 and the fixing screw block 72 to rotate, fixing the position between the connecting frame 5 and the vertical plate 3. When the second clutch disc 76 stops rotating (i.e., when the second long shaft 79 stops rotating), the twisting block 73 rotates back to its original position under the action of the torsion spring 74, rotating the fixing screw block 72 back to its original position. At this time, relative movement can occur between the connecting frame 5 and the vertical plate 3.

[0053] The working principle of the present invention is as follows:

[0054] When the present invention is in use, first, the arc-shaped frame 2 can be placed at the back of the patient's head, and the arc-shaped plates 4 can be respectively placed on both sides of the patient's face. Under the action of the first spring 23, the arc-shaped plates 4 are deformed to fit the patient's face. Then, the air bag 22 can be pinched by hand to fill the inflation air bag 21 with gas. After the inflation air bag 21 expands in the extrusion bag 20, the liquid in the extrusion bag 20 enters the protection bag 10, so that the protection bag 10 can be close to the patient's face and fit the patient's face more tightly. When the patient is impacted or vibrated during transportation, since the fixing pad 1 and the arc-shaped frame 2 are slidably connected through the rotating wheels 18, the vibration and even impact during transportation can be effectively absorbed. At this time, the sound insulation pad 11 is located at the patient's ear position, and the sound insulation pad 11 and the protection bag 10 cooperate with each other, which can not only fix the patient's head, but also the sound insulation pad 11 can reduce the noise received by the patient during air transportation. By inflating the neck air bag 12, the patient's neck can be supported. When the patient is transported in a horizontal (lying) state, the fixing pad 1 can be fixed at the end of the patient's hospital bed through the first fixing plate 15, the first fixing frame 13 and the fixing screw rod 14. When the patient is in a sitting transportation state, the first fixing plate 15, the first fixing frame 13 and the fixing screw rod 14 can be fixed at the backrest of the patient's seat, and the fixing pad 1 can still be fixed. Then, the injured eyelid of the patient can be opened by the eyelid opening mechanism 8, reducing the risk of secondary downward pressure on the foreign body in the eye after the patient's eyelid is closed. After the eyelid of the patient is opened by using the eyelid opening mechanism 8, the connecting frame 5 can be moved to a suitable position and then the electromagnetic switch 29 is turned on. At this time, the electrorheological fluid in the fixed pipe 28 becomes solid under the action of the electric field, and the eyelid opening mechanism 8 is fixed. Then, after the small motor 47 is started, the liquid medicine in the wetting syringe 26 will intermittently pass through the second wetting pipe 25 and the first wetting pipe 24 and enter the patient's eye, continuously nursing and treating the patient's eye, continuously wetting and relieving pain for the opened eye of the patient. At the same time, the cold compress frame 9 will move up and down in a cycle, and the patient's face will be cold-compressed and swollen through the cold compress balls 65.

[0055] The structure of the present invention is novel, the concept is ingenious, and the operation is simple and convenient. Through this design, the purpose of effectively helping patients to protect their heads during air transportation and medical evacuation is achieved, the function of being able to adapt to the situation that it is not easy to transport patients lying flat during air transportation is realized, the function of being able to reduce the vibration of the patient's wound during air transportation is increased, the risk of secondary injury to the patient's wound during transportation is reduced, the purpose of being able to continuously medicate and moisten the patient's eyes and relieve pain is realized, the purpose of being able to conveniently replace the liquid medicine for moistening the patient's eyes is achieved, the function of being able to automatically reciprocate and cold-compress the patient's face is increased, the purpose of being able to cold-compress according to the patient's facial contour is achieved, and the noise received by the patient during air transportation is reduced.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
