[0059] The lifting worm gear is mounted on the lifting ball nut assembly, and the lifting worm gear meshes with the lifting worm.

[0060] The working principle and beneficial effects of this invention are as follows:

[0061] 1. In this invention, before transferring a critically ill patient from a hospital bed, the transfer power box is pushed to one side of the bed by pushing the handle and the self-locking casters. Then, the self-locking casters are locked to fix the position of the transfer power box. By rotating the lifting turntable, the rotation of the lifting turntable drives the lifting rod to rotate, which in turn drives the main bevel gear to rotate. The rotation of the main bevel gear drives the driven bevel gear that meshes with it to rotate, which in turn drives the lifting worm gear connected to it to rotate. The lifting worm gear drives the lifting worm wheel to rotate, which in turn drives the lifting ball nut assembly to rotate. The rotation of the lifting ball nut assembly causes the lifting screw to move longitudinally. The movement of the lifting screw drives the transfer power box to move, which in turn drives the transfer moving mechanism to move, making the transfer moving mechanism flush with the upper surface of the hospital bed.

[0062] 2. In this invention, after the position of the transfer and moving mechanism is completed, the adjustment turntable is rotated. The rotation of the adjustment turntable drives the adjustment worm gear to rotate, the rotation of the adjustment worm gear drives the adjustment worm wheel to rotate, and the rotation of the adjustment worm wheel drives the adjustment rod to rotate. The rotation of the adjustment rod drives the transparent isolation cover to rotate, and the transparent isolation cover opens from the transfer power box. With the self-locking cooperation of the adjustment worm gear and the adjustment worm wheel, the stability of the position of the transparent isolation cover can be effectively ensured.

[0063] 3. In this invention, during the transfer of critically ill patients in hospital beds, a sliding toothed plate adjusting frame moves, causing the transmission toothed plate to mesh with adjacent transmission teeth. Then, a power turntable rotates, causing a power rod to rotate, which in turn rotates a transfer worm gear, which in turn rotates a transfer worm wheel, which in turn rotates a transfer screw. The rotation of the transfer screw causes the transfer ball nut assembly to move away from the power rod. This movement of the ball nut assembly then moves the transfer slide, which in turn moves the transfer support, which in turn moves the transfer rollers, transfer belt, and support. The transfer belt moves towards the patient's side on the hospital bed, allowing the transfer stent to be inserted behind the patient. As the transfer stent is inserted, the movement of the transfer belt roller drives the transmission gear. The transmission gear rotates on its own axis as it moves on the transmission gear plate, which in turn drives the transfer belt roller connected to it to rotate. Through the movement of the transfer belt roller, the transfer belt moves along the direction from the patient to the transfer power box. Since the transfer stent moves along the direction from the power box to the patient, the position where the transfer belt contacts the patient's back is stationary. This allows the transfer stent to be inserted under the patient's body to support the patient without causing friction damage.

[0064] 4. In this invention, after the patient is supported on the transfer belt by the rotation of the power turntable, the sliding toothed plate adjustment frame separates the transmission toothed plate from the transmission gear. By reversing the power turntable, the transfer bracket is moved back into the rotating power box, thereby smoothly transferring the patient to the transport power box.

[0065] 5. In this invention, when the transfer stent is moved toward the patient's side by rotating the power rod, the transfer stent first contacts the sealing cover plate. As the transfer stent continues to move, the sealing cover plate will rotate in an arc around the sealing rod. The rotation of the sealing cover plate causes the cover plate adjustment spring to twist and deform. When the transfer stent moves into the rotating power box again, under the action of the rebound force of the cover plate adjustment spring, it will once again drive the sealing cover plate to make sealing contact with one side of the rotating power box.

[0066] 6. In this invention, after the patient is transferred to the top of the transport power box, the transparent isolation chamber cover is resealed with the transport power box and the sealing cover plate by reversing the positioning turntable. This allows the critically ill patient to be placed in the isolation cavity. Compared with the traditional transfer method that relies on manual handling, this method not only greatly reduces the time that medical staff have to contact the patient, but also provides stable support for the patient. The transfer method is better and safer. Furthermore, to prevent the transport power box from tipping over during the transfer process, medical staff can apply counterweights to ensure stability during the transfer.

[0067] 7. In this invention, after the patient is transferred into the isolation cavity, the sealing cover on one of the exhaust pipes is unscrewed, and the exhaust fan is turned on. Under the action of air pressure, the outside air will enter the isolation cavity through the air inlet pipe and the air inlet one-way valve. The air in the isolation cavity will be discharged from the exhaust pipe through the air exchange pipe, air exchange box, and purification box. When the air in the isolation cavity passes through the purification box, the purification filter will purify the viruses and other substances in the air. Through the rotation of the exhaust fan, not only can the oxygen required by the human body be provided in the isolation cavity, but the virus carried by the patient can also be blocked and filtered through the purification filter to prevent infection to the transporting medical staff.

[0068] 8. In this invention, after transferring medical personnel to the destination, similarly, after opening the transparent isolation chamber cover, the patient is placed on the destination hospital bed via the belt transfer unit. Then, by using the sliding toothed plate adjustment frame, the transmission toothed plate meshes with the transmission gear. When the belt transfer unit moves towards the transfer power box, the patient can be placed on the hospital bed without causing excessive friction to the patient.

[0069] 9. In this invention, during transport, medical staff can adjust the patient's position or provide simple guidance and assistance using rubber isolation gloves. Attached Figure Description

[0085] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0086] like Figures 1 to 12As shown in the figure, this embodiment proposes an isolation cabin for the transfer of critically ill patients, including a transfer power box 1, a transfer moving mechanism 002 with height adjustment function, a transparent isolation cabin cover 2, a ventilation and purification component 004, and a belt transfer mechanism 005 with telescopic passenger carrying function.

[0087] The transfer power box 1 is rotatably equipped with a box sealing assembly 001 on one side. The box sealing assembly 001 includes a sealing cover plate 17 and a sealing rotating rod. The sealing cover plate 17 is provided with multiple cover plate adjusting blocks 18. Each cover plate adjusting block 18 is provided with a cover plate adjusting spring 19 on both sides. The sealing cover plate 17 is in sealing contact with the transfer power box 1 and the transparent isolation chamber cover 2. The sealing rotating rod is rotatably arranged on one side of the transfer power box 1. The cover plate adjusting blocks 18 are arranged on the sealing cover plate 17. The sealing rotating rod is located inside the cover plate adjusting spring 19. The other end of the cover plate adjusting spring 19 is connected to the transfer power box 1.

[0088] Specifically, when the sealing cover 17 is subjected to pressure on the side near the rotating power box, the sealing cover 17 will rotate in an arc around the sealing rod as the center under the pressure, so that the components inside the rotating power box can move to one side of the rotating power box.

[0089] like Figure 1 and Figure 6 As shown above, the transfer and moving mechanism 002 is located at the bottom of the transfer power box 1. The transfer and moving mechanism 002 includes a moving box 34, a lifting rod 36, a main bevel gear 38, and a lifting and moving part. A push handle 35 is provided on one side of the moving box 34. The lifting rod 36 passes through and is rotatably mounted on the moving box 34. A lifting turntable 37 is provided at one end of the lifting rod 36. There are multiple main bevel gears 38, which are mounted on the lifting rod 36. There are multiple sets of lifting and moving parts, which are mounted on the moving box 34. The lifting and moving parts mesh with the main bevel gears 38 and are connected to the transfer power box 1. They are used to adjust the height of the transfer power box 1 and to drive the transfer power box 1 to move.

[0090] The lifting and moving part includes a lifting cylinder 39, a self-locking universal wheel 40, a lifting screw 41, a lifting worm gear 43, and a lifting worm wheel 44. The lifting cylinder 39 is installed through the moving box 34. The self-locking universal wheel 40 is located on the side of the lifting cylinder 39 away from the moving box 34. One end of the lifting screw 41 is located at the bottom of the transfer power box 1, and the other end of the lifting screw 41 is installed through the lifting cylinder 39. A lifting ball nut assembly 42 is threaded onto the lifting screw 41. The lifting ball nut assembly 42 is rotatably mounted on the lifting cylinder 39. One end of the lifting worm gear 43 is rotatably mounted on the moving box 34. The other end of the lifting worm gear 43 is provided with a driven bevel gear, which meshes with the adjacent main bevel gear 38. The lifting worm wheel 44 is located on the lifting ball nut assembly 42 and meshes with the lifting worm gear 43.

[0091] Specifically, before transferring a critically ill patient from the hospital bed, the transfer power box 1 is pushed to one side of the bed by pushing the handle 35 and the self-locking caster 40. Then, the self-locking caster 40 is locked to fix the position of the transfer power box 1. By rotating the lifting turntable 37, the rotation of the lifting turntable 37 drives the lifting rod 36 to rotate. The rotation of the lifting rod 36 drives the main bevel gear 38 to rotate. The rotation of the main bevel gear 38 drives the driven bevel gear that meshes with it to rotate. The rotation of the driven bevel gear drives the lifting worm gear 43 connected to it to rotate. The lifting worm gear 43 drives the lifting worm wheel 44 to rotate. The rotation of the lifting worm wheel 44 drives the lifting ball nut assembly 42 to rotate. The rotation of the lifting ball nut assembly 42 causes the lifting screw 41 to move longitudinally. The movement of the lifting screw 41 drives the transfer power box 1 to move. The movement of the transfer power box 1 drives the transfer moving mechanism 002 to move, so that the transfer moving mechanism is flush with the upper surface of the hospital bed.

[0092] It should be noted that, in order to reduce excessive ground vibration force on the transfer power box 1 during the transfer process, a shock-absorbing mechanism can be set between multiple self-locking casters 40 or between each self-locking caster 40 and the lifting cylinder 39. The specific shock-absorbing structure is not the main innovation of this application and will not be described in detail here.

[0093] As described above, the transparent isolation cover 2 is installed at the bottom of the transfer power box 1 by the cover adjustment component 003 with self-locking function. The edge of the transparent isolation cover 2 is in sealed contact with the surface of the transfer power box 1 and one side of the box sealing component 001 to form an isolation cavity. The transparent isolation cover 2 is also provided with multiple auxiliary through holes, and each auxiliary through hole is sealed and detachably equipped with a rubber isolation glove.

[0094] The hatch cover adjustment assembly 003 includes an adjustment lever 20, an adjustment worm 21, and an adjustment worm wheel 23. The adjustment lever 20 is rotatably mounted on the side of the transfer power box 1 away from the sealing cover plate 17. The transparent isolation hatch cover 2 is mounted on the adjustment lever 20. One end of the adjustment worm 21 is rotatably mounted on the transfer power box 1. The other end of the adjustment worm 21 is provided with an adjustment turntable 22. The adjustment worm wheel 23 is mounted on the adjustment lever 20 and meshes with the adjustment worm 21.

[0095] Specifically, rotating the adjustment turntable 22 causes the adjustment worm gear 21 to rotate, which in turn drives the adjustment worm wheel 23 to rotate. The rotation of the adjustment worm wheel 23 then drives the adjustment rod 20 to rotate, which in turn drives the transparent isolation cover 2 to rotate. The transparent isolation cover 2 opens from the transfer power box 1. With the self-locking cooperation of the adjustment worm gear 21 and the adjustment worm wheel 23, the stability of the position of the transparent isolation cover 2 can be effectively ensured. During the transfer, medical staff can adjust the position of the patient or provide simple guidance and assistance through rubber isolation gloves.

[0096] like Figure 1 and Figure 7 As shown above, the ventilation and purification assembly 004 is located on one side of the transfer power box 1 and is connected to the isolation cavity.

At least two exhaust purification sections are provided, which are connected to the ventilation box 24. Multiple intake pipes 26 are provided, which are connected to the side of the transparent isolation cover 2 away from the exhaust purification section. An intake one-way valve 27 is installed on the intake pipe 26.

[0097] The exhaust purification unit includes a purification box 28 and an exhaust pipe 30. The purification box 28 is connected to one side of the air exchange box 24. A purification filter 29 is detachably installed inside the purification box 28. The exhaust pipe 30 is connected to the purification box 28. An exhaust fan 31 with an electric storage function is installed inside the exhaust pipe 30. A threaded sleeve 32 is also provided on the outer surface of the exhaust pipe 30. A sealing cover 33 is threadedly connected to the threaded sleeve 32.

[0098] Specifically, after transferring the patient into the isolation cavity, unscrew the sealing cover 33 on one of the exhaust pipes 30, turn on the exhaust fan 31, and under the action of air pressure, outside air will enter the isolation cavity through the air inlet pipe 26 and the air inlet one-way valve 27. The air in the isolation cavity will be discharged from the exhaust pipe 30 through the air exchange pipe 25, the air exchange box 24, and the purification box 28. When the air in the isolation cavity passes through the purification box 28, the purification filter 29 will purify the viruses and other substances in the air. Through the rotation of the exhaust fan 31, not only can the oxygen needed by the human body be provided in the isolation cavity, but the purification filter 29 can also block and filter the viruses carried by the patient to prevent them from being transmitted to the medical staff who are transporting the patient.

[0099] By setting up at least two exhaust purification units, with at least one as a backup, problems such as malfunctions of the other exhaust fans 31 can be avoided.

[0103] The belt transfer unit includes a transfer bracket 10, a transfer belt roller 11, a support belt roller 13, a transmission gear 14, and a transmission toothed plate 15. The transfer bracket 10 is slidably disposed in the transfer groove and is mounted on the transfer slide cylinder 7. There are two transfer belt rollers 11, which are rotatably mounted on the transfer bracket 10. A transfer belt 12 is driven between the two transfer belt rollers 11. There are multiple support belt rollers 13, which are rotatably mounted on the transfer bracket 10 at equal distances. The multiple support belt rollers 13 are located between the two transfer belt rollers 11 and are in contact with the back of the transfer belt rollers 11. The transmission gear 14 is disposed at one end of the transfer belt roller 11 near the power rotating rod 3. A transmission groove is provided on the transfer power box 1. The transmission toothed plate 15 is slidably disposed in the transmission groove and meshes with the transmission gear 14. The multiple transmission toothed plates 15 are connected by a toothed plate adjusting frame 16, which is slidably disposed on the transfer power box 1.

[0104] Specifically, after the position of the transfer and moving mechanism 002 is determined, the adjusting turntable 22 is rotated. The rotation of the adjusting turntable 22 drives the adjusting worm gear 21 to rotate, which in turn drives the adjusting worm wheel 23 to rotate. The rotation of the adjusting worm wheel 23 drives the adjusting rod 20 to rotate, which in turn drives the transparent isolation cover 2 to rotate. The transparent isolation cover 2 opens from the transfer power box 1. With the self-locking cooperation of the adjusting worm gear 21 and the adjusting worm wheel 23, the stability of the position of the transparent isolation cover 2 can be effectively ensured.

[0105] Furthermore, during the transfer of critically ill patients from hospital beds, the sliding toothed plate adjusting frame 16 drives the transmission toothed plate 15 to move, causing the transmission toothed plate 15 to mesh with adjacent transmission teeth. Then, the power turntable 4 is rotated, which drives the power rod 3 to rotate. The rotation of the power rod 3 drives the transfer worm gear 8 to rotate, which drives the transfer worm wheel 9 to rotate. The rotation of the transfer worm wheel 9 drives the transfer screw 5 to rotate. The rotation of the transfer screw 5 causes the transfer ball nut assembly 6 to move away from the power rod 3. The movement of the transfer ball nut assembly 6 drives the transfer slide 7 to move, which in turn drives the transfer bracket 10 to move. The movement of the transfer bracket 10 drives the transfer belt roller 11, the transfer belt 12, and the support belt roller 13 to move towards the side of the patient on the hospital bed, allowing the transfer bracket 10 to be inserted behind the patient. As the transfer bracket 10 moves and inserts, the transfer belt... The movement of roller 11 drives the transmission gear 14 to move. While the transmission gear 14 moves on the transmission gear plate 15, it also rotates. The rotation of the transmission gear 14 drives the transfer belt roller 11 connected to it to rotate. Through the movement of the transfer belt roller 11, the transfer belt 12 moves along the direction from the patient to the transfer power box 1. Since the transfer bracket 10 moves along the direction from the rotation power box to the patient, the position where the transfer belt 12 contacts the back of the patient is in a stationary state. Without causing friction damage to the patient, the transfer bracket 10 can be inserted under the patient's body to support the patient. After the patient is supported on the transfer belt 12 by the rotation of the power turntable 4, the sliding gear plate adjustment frame 16 separates the transmission gear plate 15 from the transmission gear 14. By reversing the power turntable 4, the transfer bracket 10 is moved back into the rotation power box, thereby smoothly transferring the patient to the transfer power box 1.

[0106] Furthermore, after transferring medical personnel to the destination, similarly, after opening the transparent isolation chamber cover 2, the patient is placed on the destination hospital bed via the belt transfer unit. Then, by sliding the toothed plate adjustment frame 16, the transmission toothed plate 15 is engaged with the transmission gear 14. When the belt transfer unit moves towards the transfer power box 1, the patient can be placed on the hospital bed without causing excessive friction to the patient, thus completing the transfer of critically ill patients.

[0107] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
