Description

Technical Field

[0001] The invention relates to the field of ambulances, in particular to a protective monitoring type negative pressure ambulance capable of eliminating cross infection. Background Art

[0002] The protective monitoring negative pressure ambulance is a special type of ambulance with negative pressure isolation function, which can minimize the chance of cross infection among medical staff. It can provide better protection and monitoring conditions when treating and transporting special diseases such as infectious diseases. In addition, this ambulance is also equipped with a full set of advanced medical facilities, such as ventilators, ECG monitors, defibrillators, stretchers, etc., as well as ultraviolet disinfection lamps, central oxygen supply interfaces and other equipment. These facilities can be used to carry out pre-hospital rescue, transportation and monitoring of ordinary or infectious patients.

[0003] When transporting infectious patients, medical staff and patients are in the same enclosed contaminated area in the ambulance medical cabin, and they have to rely entirely on self-protection to fight the virus. To ensure the safety of medical staff and reduce the chance of being infected in the same enclosed space with patients, two vehicles are used to transport one confirmed patient, one specifically for transporting the patient and one to carry medical staff, so that timely treatment can be given to the patient when he or she becomes unwell and needs medical intervention. This causes a lot of waste of resources, reduces the opportunity for treatment of patients in sudden conditions, and increases the chance of infection for the second vehicle's personnel. Chinese patent CN218589265U discloses a three-zone two-channel protective monitoring negative pressure ambulance for epidemic prevention and control. The medical cabin is scientifically and reasonably divided into zones. Medical staff and patients are in the same medical cabin, but in different airflow spaces, which can effectively protect medical workers from viruses. When patients feel unwell and need medical intervention, they can be treated in time, and the opportunity to treat patients' emergencies will not be missed. Each zone has a closed door for interlocking. During normal operation, only the door of one zone can be opened, and the doors of two or three zones are not allowed to be opened at the same time, thereby avoiding cross infection to the greatest extent. The negative pressure system of the medical cabin is used to reasonably control the air pressure in each zone to prevent air flow from entering the semi-contaminated area and the clean area from the contaminated area, thereby avoiding contamination of the clean area to the greatest extent.

[0004] In the above scheme, the passage doors from the semi-contaminated area to the clean area and the contaminated area cannot be opened at the same time. When a patient has an emergency and needs timely treatment by medical staff, multiple medical staff need to completely enter the semi-contaminated area, close the passage door to the clean area, and then open the passage door to the contaminated area, which will delay for a long time and affect the rescue of the patient.

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figures 1 to 12As shown: a protective monitoring type negative pressure ambulance for eliminating cross infection, comprising a medical cabin 1, the medical cabin 1 comprising a first partition board 11, a second partition board 12 and a third partition board 13, a first airtight door 14 and a second airtight door 15, the first partition board 11, the second partition board 12, the third partition board 13 and the bulkhead of the medical cabin 1 divide the internal space of the medical cabin 1 into an isolation area, a buffer area and an observation area, the second partition board 12 is provided with two door openings, the two door openings face the isolation area and the observation area respectively, the first airtight door 14 and the second airtight door 15 are respectively arranged on the two door openings, and face the isolation area and the observation area respectively, the third partition board 13 is provided with an observation window, and also comprises an interlocking mechanism 2, a disinfection and air-drying mechanism 3 and an anti-locking structure 4; the interlocking mechanism 2 is arranged at the upper ends of the first airtight door 14 and the second airtight door 15, and the interlocking mechanism 2 makes the first airtight door 14 and the second airtight door 15 The closed door 14 and the second closed door 15 cannot be opened at the same time. The interlocking mechanism 2 includes a lock release mechanism 25, which is used to release the effect of the interlocking mechanism 2 on the first closed door 14 and the second closed door 15; the disinfection and air-drying mechanism 3 is arranged in the buffer zone, and the disinfection and air-drying mechanism 3 is used to disinfect and dry the medical staff; the anti-locking structure 4 is arranged on the first closed door 14 and in the buffer zone, and the anti-locking structure 4 is used to prevent the first closed door 14 from being opened from the isolation zone side; the protective monitoring type negative pressure ambulance for eliminating cross infection also includes an emergency switch, an exhaust structure and a drainage structure (not shown in the figure), the emergency switch is used to transmit a signal to the lock release mechanism 25 to make the lock release mechanism 25 work, the exhaust structure is used to discharge the vaporized disinfectant in the buffer zone, and the drainage structure is used to discharge the disinfectant that falls on the ground of the medical cabin 1.

[0036] The patient is in the isolation area, and the medical staff is in the observation area. The anti-locking structure 4 is used to close the first sealed door 14 from the buffer area, so that the patient cannot open the first sealed door 14 to enter the buffer area and the observation area. The interlocking mechanism 2 allows only one sealed door to be opened at a time. Under normal circumstances, the medical staff opens the second sealed door 15 to enter the buffer area from the observation area. The disinfection and air-drying mechanism 3 disinfects and air-dries the protective clothing worn by the medical staff. After the disinfection is completed, the medical staff opens the first sealed door 14 to enter the isolation area from the buffer area. When the patient encounters an emergency, multiple medical staff are required to enter the isolation area for rescue, and the second sealed door 15 needs to be The first airtight door 14 can only be closed and opened after multiple medical staff have completely entered the buffer zone, so that the patient cannot be rescued in the first time. By setting the lock release mechanism 25, the medical staff touches the emergency switch at the first time of opening the second airtight door 15, and the emergency switch transmits the signal to the lock release mechanism 25. The lock release mechanism 25 works, and the interlocking mechanism 2 loses the locking effect on the first airtight door 14 and the second airtight door 15. The medical staff can therefore open the first airtight door 14 and the second airtight door 15 at the same time, so that the medical staff can rescue the dangerous patients in time and reduce the time patients wait for rescue.

[0037] Reference Figure 3 and Figure 4 As shown: the interlocking mechanism 2 includes two locking rods 21, two rollers 22 and a transverse self-locking structure 23; the two locking rods 21 correspond to the first airtight door 14 and the second airtight door 15 respectively; the two rollers 22 are respectively arranged at the lower ends of the two locking rods 21, and the rollers 22 are axially connected to the locking rods 21; the transverse self-locking structure 23 is arranged in the middle of the two locking rods 21, and the transverse self-locking structure 23 is used to drive the two locking rods 21 to move simultaneously, and the transverse self-locking structure 23 includes a first mounting frame 231, a first guide rod 232, a first slider 233, a first spring 234, a second spring 235 and a connecting plate 236, The first mounting frame 231 is connected to the second partition plate 12, the two ends of the first guide rod 232 are respectively connected to the two ends of the first mounting frame 231, and the first guide rod 232 is parallel to the upper surfaces of the first sealed door 14 and the second sealed door 15, the first slider 233 is slidably set on the first guide rod 232, the first spring 234 and the second spring 235 are respectively set at the two ends of the first slider 233, and the first spring 234 and the second spring 235 are both sleeved on the first guide rod 232, the middle part of the connecting plate 236 is connected to the first slider 233, and the two ends of the connecting plate 236 are respectively connected to the two locking rods 21.

[0038] When the medical staff opens the first sealed door 14, the first sealed door 14 pushes the locking rod 21 abutting against it to move, and the roller 22 rolls to reduce the friction between the locking rod 21 and the first sealed door 14. The locking rod 21 pushes the first slider 233 to move along the first guide rod 232, and the locking rod 21 at the other end of the first slider 233 moves with the first slider 233, the first spring 234 is stretched, and the second spring 235 is compressed, and the locking rod 21 is always in contact with the second sealed door. 15 abuts, the locking rod 21 applies a force to the second airtight door 15 toward the second partition plate 12, so that the second airtight door 15 cannot be opened. After the medical staff removes the force on the first airtight door 14, the first spring 234 and the second spring 235 are both reset, so that the two locking rods 21 return to the middle of the first airtight door 14 and the middle of the second airtight door 15 again. Similarly, the movement process for opening the second airtight door 15 is the same, so that only one door can be opened at a time to prevent cross infection.

[0039] Reference Figure 4 and Figure 5 As shown: the interlocking mechanism 2 also includes two elastic connection structures 24, which are respectively arranged at the upper ends of the two locking rods 21. The elastic connection structure 24 enables the locking rod 21 to be away from the second partition plate 12. The elastic connection structure 24 includes a first connection block 241, a second connection block 242 and a third spring 243. The first connection block 241 is connected to the upper end of the locking rod 21, the second connection block 242 is sleeved on the outside of the first connection block 241, and the second connection block 242 is connected to the connecting plate 236. The third spring 243 is arranged inside the second connection block 242, and the two ends of the third connection block are respectively connected to the first connection block 241 and the second connection block 242.

[0040] The distance between the locking rod 21 and the second partition plate 12 is fixed, and the locking rod 21 is far from the hinge between the first airtight door 14 and the second partition plate 12, so that the force applied by the medical staff to the first airtight door 14 is close to the locking rod 21. Therefore, when the medical staff opens the first airtight door 14, a large force is required to push the locking rod 21 to move. By setting the elastic connection structure 24, the first airtight door 14 applies a thrust to the locking rod 21, the third spring 243 is compressed, and the first connecting block 241 is retracted into the second connecting block 242. The distance between the locking rod 21 and the second partition plate 12 increases, and the locking rod 21 is always pressed against the first airtight door 14. At this time, there is a certain angle between the first airtight door 14 and the second partition plate 12, and the force applied by the locking rod 21 to the first airtight door 14 is decomposed. Similarly, the opening process of the second airtight door 15 is the same, so that the medical staff only needs to use a small force to open the airtight door.

[0041] Reference Figure 3 and Figure 6As shown, the lock release mechanism 25 includes two second mounting frames 251, a bidirectional screw 252, a second guide rod 253, two second sliders 254, two drive plates 255 and a first driver 256; the two second mounting frames 251 are both arranged on the transverse self-locking structure 23, and the two second mounting frames 251 are respectively connected to the two ends of the first slider 233; the two ends of the bidirectional screw 252 are respectively axially connected to the two second mounting frames 251; the two ends of the second guide rod 253 are respectively connected to the two second mounting frames 251, and the second guide rod 253 is parallel to the bidirectional screw 252; the two second sliders 254 are respectively slidably arranged at the two ends of the second guide rod 253, and the second slider 254 is threadedly connected to the bidirectional screw 252; the two drive plates 255 are respectively arranged at the two ends of the second guide rod 253, one end of the drive plate 255 is axially connected to the second slider 254, and the other end of the drive plate 255 is axially connected to the connecting plate 236, and the two drive plates 255 are used to drive the two locking rods 21 to move up and down.

[0042] The medical staff triggers the emergency switch, and the first driver 256 works accordingly. The first driver 256 drives the bidirectional screw 252 to rotate, and the bidirectional screw 252 drives the two second sliders 254 to move toward each other along the bidirectional screw 252. The two second sliders 254 drive the connecting plate 236 to move upward through the two driving plates 255, and the connecting plate 236 drives the two locking rods 21 to move upward, so that the two locking rods 21 move out of the rotation coverage of the first sealed door 14 and the second sealed door 15, so that the two locking rods 21 lose the force on the first sealed door 14 and the second sealed door 15.

[0043] Reference Figure 3 and Figure 7 As shown: the interlocking mechanism 2 also includes an auxiliary structure 27, which keeps the two locking rods 21 moving up and down along their own axes respectively. The auxiliary structure 27 includes a first mounting plate 271, a third guide rod 272 and a fourth spring 273. The first mounting plate 271 is arranged at the lower end of the connecting plate 236, and the first mounting plate 271 is connected to the first slider 233. There are at least two third guide rods 272, and the two third guide rods 272 are arranged in parallel. One end of the third guide rod 272 is connected to the first mounting plate 271, and the axis of the third guide rod 272 is parallel to the axis of the locking rod 21. The other end of the third guide rod 272 passes through the connecting plate 236 upward. The restriction of the two third guide rods 272 prevents the connecting plate 236 from rotating. There are at least two fourth springs 273, and the two fourth springs 273 are respectively sleeved on the two third guide rods 272. One end of the fourth spring 273 abuts against the first mounting plate 271, and the other end of the fourth spring 273 abuts against the connecting plate 236.

[0044] The connecting plates 236 have the same length, and the lock release mechanism 25 will apply a force on both ends of the connecting plate 236 that is inclined toward the middle of the connecting plate 236, causing the two locking rods 21 to tilt. By setting an auxiliary structure 27, multiple third guide rods 272 keep the connecting plate 236 horizontal, and at the same time the fourth spring 273 applies an upward force to the connecting plate 236, so that each part of the connecting plate 236 is subjected to an upward force, thereby preventing the locking rod 21 from tilting.

[0045] Reference Figure 2 , Figure 8 and Fig. 9 As shown: the disinfection and air-drying mechanism 3 includes a disinfection structure 31, an air-drying structure 32 and a driving structure 33; the disinfection structure 31 includes two disinfectant spraying pipes 311, the two disinfectant spraying pipes 311 are respectively arranged on both sides of the buffer zone, and a spraying port is opened on the disinfectant spraying pipe 311; the air-drying structure 32 includes two air dryers 321, and the two air dryers 321 are respectively arranged at the upper ends of the two disinfectant spraying pipes 311; the driving structure 33 includes two first screws 331, two second screws 332, a first driving unit 333 and a second driving unit 334, the two first screws 331 respectively drive the two disinfectant spraying pipes 311 to move up and down, and the two second screws 332 respectively drive the two air dryers 321 to move up and down The first driving unit 333 is used to drive the two first screw rods 331 to rotate in the same direction at the same time. The first driving unit 333 includes two driven wheels 3331, a second driver 3332, a driving wheel 3333 and a transmission belt 3334. The two driven wheels 3331 are respectively connected to the two first screw rods 331. The second driver 3332 is arranged between the two first screw rods 331. The driving wheel 3333 is connected to the output shaft of the second driver 3332. The transmission belt 3334 is sleeved on the two driven wheels 3331 and the driving wheel 3333. The second driving unit 334 is used to drive the two second screw rods 332 to rotate in the same direction at the same time. The structure of the second driving unit 334 is the same as that of the first driving unit 333.

[0046] After the medical staff enters the buffer zone, the first sealed door 14 and the second sealed door 15 are closed, the driving structure 33 works, and the disinfection structure 31 works first. A first driving unit 333 drives the two first screws 331 to rotate, and the two first screws 331 simultaneously drive the two disinfectant spraying pipes 311 to move from top to bottom, and the disinfectant is sprayed on the protective clothing worn by the medical staff. Then the other first driving unit 333 drives the two second screws 332 to rotate, and the two second screws 332 simultaneously drive the two air dryers 321 to move from top to bottom to dry the disinfectant on the protective clothing, thereby achieving disinfection of the medical staff and preventing the medical staff from bringing viruses and bacteria into the observation area or isolation area.

[0047] Reference Fig. 9As shown: the disinfection structure 31 also includes two first moving blocks 312, a first screw sleeve 313 and a first sliding sleeve 314; the two first moving blocks 312 are respectively arranged at both ends of the disinfectant spraying pipe 311, and the two first moving blocks 312 are respectively slidably arranged on the first screw rod 331 and the second screw rod 332; the first screw sleeve 313 is threadedly connected to the first screw rod 331, and the first screw sleeve 313 and one first moving block 312 are connected; the first sliding sleeve 314 is slidably connected to the second screw rod 332, and the first sliding sleeve 314 and another first moving block 312 Connection; the air-drying structure 32 also includes two second moving blocks 322, a second screw sleeve 323 and a second sliding sleeve 324; the two second moving blocks 322 are respectively arranged at the two ends of the air dryer 321, and the two second moving blocks 322 are respectively slidably arranged on the first screw 331 and the second screw 332; the second screw sleeve 323 is threadedly connected to the second screw 332, and the second screw sleeve 323 and one second moving block 322 are connected; the second sliding sleeve 324 is slidably connected to the first screw 331, and the second sliding sleeve 324 is connected to another second moving block 322.

[0048] When the first screw 331 drives the disinfectant spray pipe 311 to move, the other end of the disinfectant spray pipe 311 slides along the second screw 332. The second screw 332 can limit the disinfectant spray pipe 311 to rotate following the first screw 331, and the rotation of the second screw 332 will not affect the movement of the disinfectant spray pipe 311. Similarly, the first screw 331 can limit the air dryer 321 to rotate following the second screw 332, and the first screw 331 will not affect the movement of the air dryer 321, so that the disinfectant spray pipe 311 and the air dryer 321 can move in steps.

[0049] Reference Figure 8 and Fig.10 As shown: the disinfection and air-drying mechanism 3 also includes a tensioning structure 34, which is used to keep the driving structure 33 driving the disinfection structure 31 and the air-drying structure 32 to move normally. The tensioning structure 34 includes a second mounting plate 341, a fourth guide rod 342, two third sliders 343, two auxiliary wheels 344 and two fifth springs 345. Both ends of the second mounting plate 341 are provided with strip grooves 3411, the fourth guide rod 342 runs through the second mounting plate 341, and the two ends of the fourth guide rod 342 are respectively arranged in the two strip grooves 3411, the two third sliders 343 are respectively slidably arranged at the two ends of the fourth guide rod 342, the two auxiliary wheels 344 are respectively arranged at the lower ends of the two third sliders 343, and the two auxiliary wheels 344 are respectively abutted against the two transmission belts 3334, and the two fifth springs 345 are respectively sleeved on the two ends of the fourth guide rod 342.

[0050] The transmission belt 3334 is affected by thermal expansion and contraction, and the total length of the transmission belt 3334 is in a changing state. By setting a tensioning structure 34, the two auxiliary wheels 344 are respectively pressed against the two transmission belts 3334, and the fifth spring 345 applies a force toward the transmission belt 3334 to the auxiliary wheels 344. When the total length of the transmission belt 3334 changes, the compression degree of the fifth spring 345 changes, so that the auxiliary wheels 344 are always pressed against the transmission belt 3334, so that the transmission belt 3334 maintains the transmission effect.

[0051] Reference Figure 2 , Fig.11 and Fig.12 As shown: the anti-locking structure 4 includes a rebound self-locking structure 41, which is used to automatically fix the first sealed door 14 and the second partition plate 12 after the first sealed door 14 is closed. The fixed connection structure includes a lock sleeve 411, a lock core 412, a U-shaped cover 413, a fifth guide rod 414, a sixth spring 415 and a push block 416. The lock sleeve 411 is mounted on the second partition plate 12, the lock core 412 is arranged on the first sealed door 14, a plug hole is opened at one end of the lock core 412, the U-shaped cover 413 is arranged on the outside of the lock core 412, one end of the fifth guide rod 414 is connected to the middle part of the U-shaped cover 413, the other end of the fifth guide rod 414 is inserted into the plug hole, the sixth spring 415 is sleeved on the fifth guide rod 414, and the push block 416 is arranged on one side of the lock core 412.

[0052] The rebound self-locking structure 41 is arranged in the buffer zone. When the first airtight door 14 is closed, one side of the lock core 412 contacts the lock sleeve 411 first. The lock sleeve 411 applies a force to the lock core 412. The lock core 412 moves along the fifth guide rod 414. The sixth spring 415 is compressed. Then the lock core 412 is aligned with the lock sleeve 411. The sixth spring 415 rebounds and pushes the lock core 412 to be inserted into the lock sleeve 411, so that the first airtight door 14 and the second partition plate 12 are fixedly connected. The first airtight door 14 is located on the side of the isolation area without a device for opening the rebound self-locking structure 41, so that the patient cannot open the first airtight door 14.

[0053] Reference Fig.11 and Fig.12As shown: the anti-locking structure 4 also includes an anti-mislocking structure 42, which is used to prevent medical staff from being unable to open the first airtight door 14 from the isolation area side. The anti-mislocking structure 42 includes a fixed mounting block 421, a third mounting plate 422, a pull rod 423, a handle 424, a sixth guide rod 425 and a seventh spring 426.

[0054] After the rebound self-locking structure 41 fixes the first airtight door 14 and the second partition board 12 together, although the patient opens the first airtight door 14, the medical staff cannot open the first airtight door 14 from the isolation area. By setting the anti-mislocking structure 42, the lock sleeve 411 and the lock core 412 are staggered, and the lock sleeve 411 is located above the lock core 412. When the medical staff enters the isolation area from the buffer zone, the first airtight door 14 is closed, and the lock core 412 cannot be inserted into the lock sleeve 411, so that the first airtight door 14 will not be locked. When the medical staff enters the buffer zone from the isolation area, the medical staff lifts up the handle 424, and the handle 424 drives the U-shaped cover 413 to move upward through the pull rod 423. After aligning the lock core 412 with the lock sleeve 411, the first airtight door 14 is closed, and the lock core 412 is inserted into the lock sleeve 411, thereby achieving the goal that the patient cannot open the first airtight door 14, and at the same time will not affect the entry and exit of medical staff.
