Description

Technical Field

[0001] This invention relates to the field of clinic technology, and in particular to a modular negative pressure isolation ward and negative pressure isolation area. Background Technology

[0002] Negative pressure wards are wards where the air pressure inside the ward is lower than the air pressure outside. Many hospitals in China can now achieve this level.

[0003] Negative pressure isolation wards are an important means of controlling the source of infection and protecting medical staff and the environment from contamination. During use, a certain amount of waste is generated in the negative pressure isolation wards, which medical staff need to transfer out. In addition, external personnel need to transfer medical supplies into the negative pressure isolation wards for their needs. This will increase the risk of medical staff coming into contact with the outside world. To address this, we propose a modular negative pressure isolation ward and negative pressure isolation area.

The conveyor channel is equipped with two fixed baffles, each with a fixed block at its upper end. Both fixed blocks are fixedly connected to the bottom end of the conveyor plate. A sliding sleeve is movably fitted onto the sliding rod, and a connecting plate is fixedly installed at the bottom end of the sliding sleeve. A fixing component is movably installed inside the connecting plate, and a hook is fixedly installed at the end of the fixing component. A material discharge port is provided on the bottom surface of the conveyor channel, and a material guide plate is provided at the material discharge port. The material guide plate is fixedly installed at the bottom end of the conveyor channel. Support legs are fixedly installed at the four corners of the bottom end of the conveyor channel. A support frame is fixedly installed on one of the support legs. The support frame has a U-shaped design, and a collection box is slidably installed inside the support frame. The collection box is located below the material guide plate, and a closed structure is provided on the collection box. The closed structure includes a connecting component and a cover plate.

[0006] As a preferred embodiment of the present invention, a support plate is provided at the feed inlet, the support plate is fixedly installed on the inner wall of the conveying channel, and the support plate is designed to be inclined.

[0007] As a preferred embodiment of the present invention, a holding frame is fixedly installed on the bottom surface of the inner wall of the conveying channel, and a sponge is provided inside the holding frame. The sponge inside the holding frame protects the medical items that slide into the holding frame and prevents damage to the medical items.

[0008] As a preferred embodiment of the present invention, a rotating rod 2 is fixedly inserted through the fixing member, a gear 2 is fixedly installed on the rotating rod 2, a rectangular block is fixedly installed at the end of the connecting plate, and a limit rod is fixedly installed at the end of the rectangular block.

[0009] As a preferred embodiment of the present invention, a rack is provided above the rotating rod 2, and a slider is fixedly installed at the upper end of the rack. A circular rod is movably inserted inside the slider, and the circular rod is fixedly installed on the rectangular block.

[0010] As a preferred embodiment of the present invention, a spring is movably sleeved on the round rod, the slider is fixedly connected to the rectangular block through the spring, and the limiting rod movably passes through the slider.

[0011] As a preferred embodiment of the present invention, a contact block is fixedly installed at the upper end of the rack, a fixing rod is fixedly installed at the bottom end of the conveying plate, and a pushing block is fixedly installed at the bottom end of the fixing rod. Both the contact block and the pushing block are trapezoidal in design.

[0012] As a preferred embodiment of the present invention, a bolt is screwed into the sliding sleeve, and the connecting plate is U-shaped.

[0013] As a preferred embodiment of the present invention, the connector is fixedly installed at the end of the material discharge port, a rotating rod three is fixedly passed through the end of the cover plate, a gear three is fixedly installed at the end of the rotating rod three, and a chain is sleeved on the gear three and the gear one.

[0014] A negative pressure isolation area includes a main body of a negative pressure isolation ward, at least one patient corridor compartment and at least one medical staff corridor compartment, wherein the main body of the negative pressure isolation ward is arranged between adjacent medical staff corridor compartments and patient corridor compartments and at least one is arranged therein.

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0016] 1. After disinfection, the medical supplies are placed into the support plate through the inlet. The medical supplies slide down the conveyor plate along the inclined direction of the support plate and into the holding frame, thus completing the transportation of the medical supplies. This isolates the medical staff inside the negative pressure isolation ward from the outside world, achieving zero contact and protecting medical workers and the environment from contamination.

[0017] 2. The sponge inside the holding frame protects the medical items that slide into it, preventing damage. Side baffles are fixedly installed on both sides of the upper part of the conveyor plate to limit and block the conveyed medical items, preventing them from falling off the sides of the conveyor plate and ensuring the landing point of the medical items.

[0018] 3. The sliding of the sliding sleeve will cause the hook and the garbage bag on the hook to slide. When the contact block contacts the surface of the pushing block, the pushing block will apply a force to the contact block, causing the slider to move horizontally. The movement of the slider will drive the rack to move. At this time, the spring is compressed. The movement of the rack will cause the second gear to rotate. The rotation of the second gear will drive the second rotating rod to rotate. The rotation of the second rotating rod will drive the hook and the fixing part to rotate around the second rotating rod as the axis, so that the garbage bag will detach from the hook and fall from the discharge port into the collection box, thus completing the collection of garbage in the main body of the negative pressure isolation ward. Medical staff do not need to go out to throw away garbage, further protecting medical staff and the environment from pollution. The structural design is reasonable and conducive to the use of medical staff.

[0019] 4. Start the motor to make the rotating rod rotate in the opposite direction, so that the lower end of the conveying plate is close to the holding frame. At this time, the sliding sleeve and hook will slide to the lower end of the sliding rod. At this time, the pushing block no longer applies force to the contact block. The contact block can be reset by using the elastic reset action of the spring, ensuring the next use of waste transfer. Both ends of the sliding rod are fixedly installed with baffles to prevent the sliding sleeve from separating from the sliding rod. The structure is reasonably designed and more convenient to use.

[0020] 5. When it is necessary to transfer the garbage inside the negative pressure isolation ward, the cover is open, allowing the garbage to enter the collection box smoothly. When it is necessary to transport medical supplies from outside to the negative pressure isolation ward, the cover is closed, which will block the upper port of the collection box and alleviate the situation where the garbage inside the collection box is exposed to the outside environment and causes pollution.

[0021] 6. A guide plate is fixedly installed at the bottom of the conveying channel. The guide plate is close to the discharge port and guides the falling garbage, ensuring that the garbage can slide smoothly into the collection box. The collection box is slidably installed in the support frame and fixed to the support frame with bolts, making it easy to remove the collection box and making it easier for staff to clean the garbage in the collection box, making it more convenient to use.

[0032] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, a modular negative pressure isolation ward includes a main body 9, which is equipped with ventilation equipment. The main body 9 contains a feeding area 91, a buffer room 92, a treatment area 93, and a toilet 94. The feeding area 91 includes a conveying channel 1 with an inlet 11 on its upper surface. A conveying plate 2 is installed inside the conveying channel 1, with side baffles 21 fixedly installed on both sides of the upper end of the conveying plate 2. A rotating rod 22 is fixedly connected to the conveying channel 1, and a gear 23 is fixedly installed at the end of the rotating rod 22. A motor 17 is fixedly installed at the end of the conveying channel 1, and the output shaft of the motor 17 is fixedly connected to the end of the rotating rod 22. A lower part of the conveying plate 2 is provided with... A sliding rod 24 is provided, with baffles 25 fixedly sleeved at both ends of the sliding rod 24. Fixing blocks 26 are fixedly installed on the upper ends of both baffles 25, and both fixing blocks 26 are fixedly connected to the bottom end of the conveying plate 2. A sliding sleeve 3 is movably sleeved on the sliding rod 24, and a connecting plate 31 is fixedly installed at the bottom end of the sliding sleeve 3. Sterilized medical items are placed into the support plate 12 through the inlet 11. The medical items slide down the conveying plate 2 along the inclined direction of the support plate 12, and then slide down into the holding frame 15, thus completing the conveying of medical items. This isolates medical staff inside the negative pressure isolation ward 9 from external personnel, achieving zero contact and protecting medical workers and the environment from contamination. A sponge 1 is installed inside the holding frame 15. 6. The conveyor plate 2 is equipped with side baffles 21 fixedly installed on both sides of its upper end, which limit and prevent the medical items from falling off the sides of the conveyor plate 2, ensuring the items land safely. When it is necessary to transfer waste from the main body 9 of the negative pressure isolation ward, the user starts the motor 17, causing the rotating rod 22 to rotate. The rotation of the rotating rod 22 drives the conveyor plate 2 to rotate, bringing the higher end of the conveyor plate 2 close to the container 15. At this time, medical staff hang the garbage bag containing the waste on the hook 33 and turn the bolt 38 so that the end of the bolt 38 no longer abuts against the container. With the sliding rod 24 in place, the sliding sleeve 3 is unobstructed and slides along the inclined direction of the conveyor plate 2 on the sliding rod 24 until it reaches the lower end of the sliding rod 24. The sliding of the sliding sleeve 3 causes the hook 33 and the garbage bag on the hook 33 to slide. When the contact block 44 contacts the surface of the pushing block 51, the pushing block 51 applies a force to the contact block 44, causing the slider 41 to move horizontally. The movement of the slider 41 causes the rack 4 to move, at which point the spring 43 is compressed. The movement of the rack 4 causes the gear 2 35 to rotate, which in turn causes the rotating rod 2 34 to rotate. The rotation of the rotating rod 2 34 causes the hook 33 and the fixing member 32 to rotate around the rotating rod 2 34 as the axis of rotation.This causes the garbage bag to detach from the hook 33 and fall from the discharge port 13 into the collection box 6, thus completing the collection of garbage inside the negative pressure isolation ward body 9. Medical staff do not need to go out to dispose of garbage, further protecting medical workers and the environment from contamination. The structural design is reasonable and convenient for medical staff to use. When it is necessary to transport external medical supplies into the negative pressure isolation ward body 9, the motor 17 is started, causing the rotating rod 22 to rotate in the opposite direction, bringing the lower end of the conveying plate 2 closer to the holding frame 15. At this time, the sliding sleeve 3 and hook 33 will slide to the lower end of the sliding rod 24. The pushing block 51 no longer applies force to the contact block 44, and the elastic reset action of the spring 43 resets the contact block 44, ensuring its continued use for the next garbage transfer. Both ends of the slide rod 24 are fixedly equipped with baffles 25 to prevent the sliding sleeve 3 from detaching from the slide rod 24. The structure is reasonably designed and more convenient to use. When it is necessary to transfer the garbage in the main body 9 of the negative pressure isolation ward, the cover plate 8 is in the open state, allowing the garbage to enter the collection box 6 smoothly. When it is necessary to transport external medical supplies into the main body 9 of the negative pressure isolation ward, the cover plate 8 is in the closed state, which will block the upper port of the collection box 6, alleviating the situation where the garbage in the collection box 6 is exposed to the outside and causes external environmental pollution. Specifically, when the rotating rod 22 rotates, it will drive the gear 23 to rotate. A chain 83 is sleeved on the gear 23 and the gear 3 82. The rotation of the gear 23 will drive the rotating rod 23 82 to rotate. 1. Rotation of the cover plate 8 opens and closes the cover plate 8. A guide plate 14 is fixedly installed at the bottom of the conveying channel 1, near the discharge port 13, guiding the falling garbage and ensuring that it slides smoothly into the collection box 6. The collection box 6 is slidably installed in the support frame 19 and fixed to the support frame 19 with bolts 2, making it easy to remove the collection box 6 and facilitate cleaning of the garbage in the collection box 6 by the staff, making it more convenient to use. A fixing part 32 is movably installed in the connecting plate 31, and a hook 33 is fixedly installed at the end of the fixing part 32. The bottom surface of the conveying channel 1 has a discharge port 13, and a guide plate 14 is set at the discharge port 13. The guide plate 14 is fixedly installed at the bottom of the conveying channel 1. Support legs 18 are fixedly installed at the four corners of the bottom of the conveying channel 1. A support frame 19 is fixedly installed on one of the support legs 18. The support frame 19 has a U-shaped design. A collection box 6 is slidably installed inside the support frame 19. The collection box 6 is located below the feed plate 14. The collection box 6 is equipped with a closed structure, which includes a connector 7 and a cover plate 8. A support plate 12 is provided at the feed inlet 11. The support plate 12 is fixedly installed on the inner wall of the conveying channel 1. The support plate 12 has an inclined design. A holding frame 15 is fixedly installed on the bottom surface of the inner wall of the conveying channel 1. A sponge 16 is placed inside the holding frame 15. A rotating rod 34 is fixedly inserted through the fixing member 32. A gear 35 is fixedly installed on the rotating rod 34. A rectangular block 36 is fixedly installed at the end of the connecting plate 31.A limiting rod 37 is fixedly installed at the end of the rectangular block 36. A rack 4 is provided above the rotating rod 34. A slider 41 is fixedly installed at the upper end of the rack 4. A round rod 42 moves through the slider 41. The round rod 42 is fixedly installed on the rectangular block 36. A spring 43 is movably sleeved on the round rod 42. The slider 41 is fixedly connected to the rectangular block 36 through the spring 43. The limiting rod 37 moves through the slider 41. A contact block 44 is fixedly installed at the upper end of the rack 4. A fixing rod 5 is fixedly installed at the bottom end of the conveying plate 2. A pushing block 51 is fixedly installed at the bottom end of the fixing rod 5. Both the contact block 44 and the pushing block 51 are trapezoidal. A bolt 38 is screwed into the sliding sleeve 3. The connecting plate 31 is U-shaped. The connecting piece 7 is fixedly installed at the end of the discharge port 13. A rotating rod 81 is fixedly inserted through the end of the cover plate 8. A gear 82 is fixedly installed at the end of the rotating rod 81. A chain 83 is sleeved on the gear 82 and gear 23.

[0034] A negative pressure isolation area includes a negative pressure isolation ward body 9, at least one patient corridor cabin and at least one medical staff corridor cabin, wherein the negative pressure isolation ward body 9 is arranged between adjacent medical staff corridor cabins and patient corridor cabins and at least one is arranged therein.

[0035] When in use, negative pressure isolation wards are an important means of controlling the source of infection and protecting medical staff and the environment from contamination. The main body 9 of the negative pressure isolation ward is equipped with independent ventilation equipment. Negative pressure isolation wards and ventilation systems are existing mature technologies and are well known to those in this technical field, so they are not described in detail.

[0036] After disinfection, the medical supplies are placed into the support plate 12 through the inlet 11. The medical supplies slide down the conveyor plate 2 along the inclined direction of the support plate 12 and into the holding frame 15, thus completing the delivery of the medical supplies. This isolates the medical staff in the main body 9 of the negative pressure isolation ward from the contact with outsiders, achieving zero contact and protecting medical workers and the environment from contamination.

[0037] The sponge 16 inside the holding frame 15 protects the medical items that slide into the holding frame 15, preventing damage to the medical items. Side baffles 21 are fixedly installed on both sides of the upper end of the conveying plate 2, which limit and block the conveyed medical items, preventing them from falling from the side of the conveying plate 2 and ensuring the landing point of the medical items.

[0038] When it is necessary to transfer garbage inside the main body 9 of the negative pressure isolation ward, the user starts the motor 17, causing the rotating rod 22 to rotate. The rotation of the rotating rod 22 will drive the conveying plate 2 to rotate, so that the higher end of the conveying plate 2 is close to the holding frame 15. At this time, the medical staff hangs the garbage bag containing garbage on the hook 33 and turns the bolt 38 so that the end of the bolt 38 no longer abuts against the sliding rod 24. At this time, the sliding sleeve 3 is not obstructed and will slide along the inclined direction of the conveying plate 2 on the sliding rod 24, and slide to the lower end of the sliding rod 24. The sliding of the sliding sleeve 3 will drive the hook 33 and the garbage bag on the hook 33 to slide. When the contact block 44 contacts the surface of the pushing block 51, the pushing block 51 will... 1. A force is applied to the contact block 44, causing the slider 41 to move horizontally. The movement of the slider 41 drives the rack 4 to move, at which time the spring 43 is compressed. The movement of the rack 4 causes the gear 35 to rotate. The rotation of the gear 35 drives the rotating rod 34 to rotate. The rotation of the rotating rod 34 drives the hook 33 and the fixing part 32 to rotate around the rotating rod 34 as the axis, causing the garbage bag to detach from the hook 33 and fall from the discharge port 13 into the collection box 6, thus completing the collection of garbage in the main body 9 of the negative pressure isolation ward. Medical staff do not need to go out to throw away garbage, further protecting medical staff and the environment from pollution. The structure is reasonably designed and is conducive to the use of medical staff.

[0039] When it is necessary to transport external medical supplies into the negative pressure isolation ward body 9, the motor 17 is started, causing the rotating rod 22 to rotate in the opposite direction, so that the lower end of the conveying plate 2 is close to the holding frame 15. At this time, the sliding sleeve 3 and the hook 33 will slide to the lower end of the sliding rod 24. At this time, the pushing block 51 no longer applies force to the contact block 44. The contact block 44 can be reset by the elastic reset action of the spring 43, ensuring the next use of waste transfer. Both ends of the sliding rod 24 are fixedly installed with baffles 25 to prevent the sliding sleeve 3 from separating from the sliding rod 24. The structure is reasonably designed and more convenient to use.

[0040] When it is necessary to transfer the garbage inside the main body 9 of the negative pressure isolation ward, the cover plate 8 is in an open state, allowing the garbage to enter the collection box 6 smoothly. When it is necessary to transport medical supplies from outside to the main body 9 of the negative pressure isolation ward, the cover plate 8 is in a closed state, which will block the upper port of the collection box 6, alleviating the situation where the garbage inside the collection box 6 is exposed to the outside and causes pollution to the external environment. Specifically, when the rotating rod 1 22 rotates, it will drive the gear 1 23 to rotate. A chain 83 is sleeved on the gear 1 23 and the gear 3 82. The rotation of the gear 1 23 will drive the rotating rod 3 81 to rotate, thereby realizing the opening and closing of the cover plate 8.

[0041] A guide plate 14 is fixedly installed at the bottom of the conveying channel 1. The guide plate 14 is close to the discharge port 13 and guides the falling garbage, ensuring that the garbage can slide smoothly into the collection box 6. The collection box 6 is slidably installed in the support frame 19 and fixed to the support frame 19 by bolt 2, which makes it easy to remove the collection box 6, so that the staff can clean the garbage in the collection box 6 and make it more convenient to use.
