Description

Technical Field

[0001] The present invention belongs to the technical field related to medical devices, and particularly relates to a movable critical care breathing device for the intensive care unit. Background Art

[0002] In modern clinical medicine, as an effective means to artificially replace the function of autonomous ventilation, ventilators have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgeries, respiratory support treatment, and first aid resuscitation, and play a very important role in the field of modern medicine. A ventilator is a crucial medical device that can prevent and treat respiratory failure, reduce complications, save and extend the lives of patients. At the same time, for critically ill patients during the transportation process, a corresponding mobile breathing device will be used;

[0003] Existing published documents disclose CN114082054A - A Movable Critical Care Ventilator, which relates to the technical field of advanced treatment equipment and services, including: a support part; a movable part is arranged on the top of the support part; the stable part is arranged on the top of the movable part; the winding part is arranged on the top of the stable part; during use, it needs to be frequently pushed to change positions. Therefore, during the movement process, when the moving wheels touch an obstacle, it is not easy to maintain balance and is prone to tipping over, resulting in equipment damage. It solves the problem that when the device tilts, the bottom frame and the top frame flip, so that the arc rod at the bottom of the top frame slides on the stable frame, thereby squeezing the strong spring at the bottom of the top frame, and thus buffering and resetting the upper part of the device under the action of the strong spring. And through the auxiliary frame, when the device quickly topples, it can contact the ground to support the device and increase its stability. However, it still has the following disadvantages in actual use:

[0004] 1. Since critically ill patients need to use the breathing device at all times when transferred to the emergency room, during the transfer process to the emergency room, medical staff need to constantly move the breathing device to ensure that the distance between the breathing device and the emergency rack does not have any accidents. Therefore, the possibility of accidents in this way is relatively large, and it cannot ensure that critically ill patients can always use the breathing device on the emergency rack, which will affect the safety of critically ill patients;

[0005] 2. When the existing devices are installed, most of them are installed integrally with bolts. Therefore, when the breathing device is damaged during use, it cannot be quickly repaired.

[0006] Therefore, the existing movable critical care breathing devices for the intensive care unit cannot meet the actual use requirements, so there is an urgent need for improved technologies on the market to solve the above problems. Summary of the Invention

[0007] The object of the present invention is to provide a movable critical care emergency breathing device for the intensive care unit. By flipping the adjustment plate, the device can be moved or suspended, improving the functionality of the device, ensuring that critically ill patients can always use the breathing device on the emergency rack. At the same time, the mutual cooperation of the baffle plate and the L-shaped plate can quickly disassemble the ventilator body, realizing quick maintenance of the ventilator body.

Push plates are connected to the left and right sides of the upper side of the L-shaped plates through bolts on the ventilator body.

[0015] Furthermore, rotation holes are provided at the positions corresponding to the rotating rods on the lower side of the housing on the left and right sides of the adjustment plate, and the rotating rods pass through the corresponding rotation holes.

[0016] Furthermore, a placement frame is fixed at the middle position on the rear side of the housing. A breathing mask is arranged at the rear side of the ventilator body above the housing, and the breathing mask is placed inside the placement frame.

[0017] Furthermore, limiting holes are formed on both the left and right sides of the strip-shaped column. Moving holes are formed on the inner end surfaces of the limiting holes, and the aperture of the moving holes is larger than that of the limiting holes.

[0018] Furthermore, telescopic rods are fixed on the side walls of the semi-circular clamping cylinders corresponding to the limiting holes. The telescopic rods pass through the limiting holes, and round plates are fixed at the ends located inside the moving holes. Return springs are sleeved on the outer sides of the telescopic rods in the moving holes, and the two ends of the return springs are respectively connected to the round plates and the inner end surfaces of the moving holes.

[0019] Furthermore, T-shaped openings are formed at the positions corresponding to the strip-shaped columns on the upper side of the adjusting plate, and the T-shaped openings penetrate through the left and right side walls of the adjusting plate. T-shaped strip plates are fixed on the side walls of the semi-circular clamping cylinders connected to the adjusting plate, and the T-shaped strip plates are respectively slidably clamped inside the corresponding T-shaped openings.

[0020] Furthermore, pressing springs are fixed at the front and rear parts on the lower side of the L-shaped plate, and the lower sides of the pressing springs are fixed on the bottom side of the placement opening.

[0024] The present invention has the following beneficial effects:

[0025] 1. The present invention is provided with an adjustment plate. When the device needs to be moved, the adjustment plate is rotated to rotate 180° inside the adjustment port. Therefore, the adjustment plate will rotate the roller inside the adjustment port to the lower position of the device. At this time, the device can be moved. When the device needs to be installed on the first aid rack, the adjustment plate is rotated 180°. At this time, the adjustment plate will rotate the semicircular cartridge inside the adjustment port to the lower position of the device, pull the semicircular cartridge, and clamp it on the armrest of the first aid rack. At this time, it is convenient to wear the breathing mask on the device on the critically ill patient. At the same time, it can ensure that the device and the first aid rack move synchronously, so that the critically ill patient can use the breathing device at all times, and the workload of medical staff can be reduced. The flipping of the adjustment plate can achieve the device being movable or suspended, thereby improving the functionality of the device.

[0026] 2. The present invention is provided with a baffle and an L-shaped plate. When the ventilator body needs to be disassembled and repaired, the baffle is rotated with the connecting shaft as the axis, so that the baffle and the restrained plate are disconnected, and then the baffle pulls the I-shaped gear rod through the pull rope, so that the I-shaped gear rod rotates in the opposite direction, thereby the I-shaped gear rod drives the L-shaped plate to move upward, so that the L-shaped plate pushes the pushing plate to drive the ventilator body to move upward, and the restrained plate is moved out from the top position of the placement port, thereby quickly disassembling the ventilator body and realizing rapid maintenance of the ventilator body.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0044] Please refer to Figures 1-12As shown in the figure, the present invention is a movable critical care breathing device for the intensive care unit, including a ventilator body 1 and a housing 2. A placement opening 204 is provided at the upper end of the housing 2, and the ventilator body 1 is located inside the placement opening 204. An adjustment opening 208 is provided at the bottom side of the housing 2. An adjustment plate 3 is arranged inside the adjustment opening 208. Roller wheels 305 are fixed at the four corners of the lower side of the adjustment plate 3. Bar-shaped columns 302 are arranged at the front and rear parts of the upper side of the adjustment plate 3, and semi-circular clamping cylinders 301 are arranged at the left and right ends of the bar-shaped columns 302. Rotating rods 304 are fixed in the middle of the left and right sides of the adjustment plate 3. The other end of the rotating rod 304 on the right side of the adjustment plate 3 is fixed with a driven gear 303. Among them, an installation shell 7 is fixed on the right side of the housing 2. A motor 701 is fixed inside the installation shell 7. The shaft end of the motor 701 is fixed with a main gear 702, and the main gear 702 is meshed and connected with the driven gear 303.

[0045] Through the above structural settings, in order to drive the rotation of the adjustment plate 3, by controlling the motor 701 to work, the motor 701 drives the rotation of the driven gear 303 through the main gear 702. Therefore, the driven gear 303 drives the rotation of the adjustment plate 3 through the rotating rod 304. At the same time, one 180° rotation of the adjustment plate 3 is one operation of the motor 701. When the adjustment plate 3 rotates each time, the roller wheels 305 or the semi-circular clamping cylinders 301 will alternately be located directly below the housing 2, so as to achieve different functions. When the roller wheels 305 are located directly below, the entire device can be moved at this time. When the semi-circular clamping cylinders 301 are located directly below the housing 2, the entire device can be sleeved on the handrail of the first aid frame to ensure that the device and the first aid frame can move synchronously.

[0046] The left and right sides of the ventilator body 1 are connected to the restricted plates 101 through bolts, and the restricted plates 101 are flush with the upper surface of the housing 2. Baffles 6 are arranged at the upper ends of the restricted plates 101. Magnetic plates 601 are fixed at the middle positions below the baffles 6 at the positions corresponding to the upper ends of the housing 2. Metal plates 206 are fixed at the left and right positions corresponding to the magnetic plates 601 on the upper end of the housing 2. Through holes 207 are provided at the left and right positions of the upper end of the housing 2 in front of and behind the metal plates 206. Notch openings 205 are provided at the positions corresponding to the through holes 207 on the left and right side walls of the placement opening 204. I-shaped toothed rods 603 are rotatably connected inside the notch openings 205. Pull ropes 604 are fixed at the middle positions on the upper surfaces of the I-shaped toothed rods 603, and the upper ends of the pull ropes 604 pass through the corresponding through holes 207 and are connected to the baffles 6. L-shaped plates 5 are arranged inside the placement opening 204 on the left and right sides of the ventilator body 1. Gear plates 501 are fixed on the sides where the L-shaped plates 5 are connected to the left and right side walls of the placement opening 204, and the gear plates 501 are meshed and connected with the corresponding I-shaped toothed rods 603. Push plates 102 are connected to the left and right sides of the upper side of the L-shaped plates 5 through bolts.

[0047] When the ventilator body 1 needs to be installed, the ventilator body 1 can be directly placed into the interior of the placement opening 204, and it is necessary to ensure that the ventilator body 1 slides stably downward. When the pushing plates 102 on the left and right sides of the ventilator body 1 are in contact with the L-shaped plate 5, the ventilator body 1 will drive the L-shaped plate 5 to move downward through the pushing plates 102. Furthermore, the L-shaped plate 5 drives the I-shaped tooth bar 603 to rotate forward in the notch 205 through the gear plate 501. Then, the I-shaped tooth bar 603 will carry out the work of gathering the pulling rope 604, so that the pulling rope 604 pulls the baffle 6, and the baffle 6 rotates around the connecting shaft rod 203. When the L-shaped plate 5 is moved to the lowest position, at this time, the restricting plate 101 is flush with the upper surface of the housing 2, and at the same time, the baffle 6 is directly located at the upper end position of the restricting plate 101, blocking the restricting plate 101 in this way. At the same time, the magnetic plate 601 on the lower side of the baffle 6 is adsorbed to the metal plate 206 at the upper end of the housing 2, so that the baffle 6 cannot rotate and shake randomly at the upper end of the housing 2, thus preventing the ventilator body 1 from jumping up and down easily inside the placement opening 204. When the ventilator body 1 needs to be disassembled and repaired, the baffle 6 is rotated around the connecting shaft rod 203, so that the baffle 6 is disengaged from the restricting plate 101. Then, the baffle 6 drives the I-shaped tooth bar 603 to move through the pulling rope 604, causing the I-shaped tooth bar 603 to rotate in the reverse direction. Thus, the I-shaped tooth bar 603 drives the L-shaped plate 5 to move upward. Therefore, the L-shaped plate 5 pushes the pushing plates 102 to drive the ventilator body 1 to move upward, and the restricting plate 101 is moved out of the top position of the placement opening 204.

[0048] As shown in Figure 2 , 6 , 10, and 12, rotation holes 202 are respectively formed in the lower sides of the housing 2 on the left and right sides of the adjusting plate 3 corresponding to the positions of the rotating rods 304, and the rotating rods 304 pass through the corresponding rotation holes 202. When the adjusting plate 3 rotates, it will drive the rotating rods 304 to rotate inside the rotation holes 202. A placement frame 201 is fixed at the middle position at the rear side of the housing 2. A breathing mask 103 is arranged at the rear side of the ventilator body 1 above the housing 2, and the breathing mask 103 is placed inside the placement frame 201. T-shaped openings 306 are respectively formed in the upper sides of the adjusting plate 3 corresponding to the positions of the strip-shaped columns 302, and the T-shaped openings 306 penetrate through the left and right side walls of the adjusting plate 3. T-shaped strip plates 3032 are respectively fixed on the side walls of the semi-circular clamping cylinders 301 connected to the adjusting plate 3, and the T-shaped strip plates 3032 are respectively slidably clamped inside the corresponding T-shaped openings 306. When the semi-circular clamping cylinders 301 move on the side walls of the adjusting plate 3, the semi-circular clamping cylinders 301 will drive the T-shaped strip plates 3032 to slide inside the T-shaped openings 306. At the same time, since the T-shaped strip plates 3032 are inside the T-shaped openings 306, the T-shaped strip plates 3032 play a role in limiting the semi-circular clamping cylinders 301 to ensure that the semi-circular clamping cylinders 301 do not shake randomly.

[0049] As shown inFigure 1 , 2 As shown in FIGS. 7, limiting holes 3021 are provided on both the left and right sides of the bar-shaped column 302. Moving holes 3022 are provided on the inner end faces of the limiting holes 3021, and the aperture of the moving hole 3022 is larger than that of the limiting hole 3021. Telescopic rods 3031 are fixed on the side walls of the semi-circular clamping cylinders 301 corresponding to the limiting holes 3021. The telescopic rods 3031 pass through the limiting holes 3021, and circular plates 3034 are fixed at the ends located inside the moving holes 3022. Return springs 3033 are sleeved on the outer sides of the telescopic rods 3031 in the moving holes 3022, and the two ends of the return springs 3033 are respectively connected to the circular plates 3034 and the inner end faces of the moving holes 3022. When adjusting the distance between the two semi-circular clamping cylinders 301 in the left and right directions of the adjusting plate 3, by moving the two semi-circular clamping cylinders 301 in opposite directions, the semi-circular clamping cylinders 301 will drive the telescopic rods 3031 to move inside the moving holes 3022. At the same time, the semi-circular clamping cylinders 301 will stretch the telescopic rods 3031, so as to adjust the distance between the semi-circular clamping cylinders 301 in the left and right directions. When the telescopic rods 3031 move inside the moving holes 3022, the telescopic rods 3031 will drive the circular plates 3034 to move. When the circular plates 3034 move towards the limiting holes 3021, the circular plates 3034 will squeeze the return springs 3033. When the semi-circular clamping cylinders 301 are released, the return springs 3033 will push the circular plates 3034, so as to reset the circular plates 3034. At the same time, the telescopic rods 3031 need to be manually operated to retract.

[0050] Among them, as Figure 1 , 3As shown in Figures 4, 8, and 10, compression springs 502 are fixed to both the front and rear portions of the lower side of the L-shaped plate 5, and the lower sides of the compression springs 502 are fixed to the bottom side of the placement opening 204. When the L-shaped plate 5 moves downward, the L-shaped plate 5 will reset the compression springs 502. At the same time, the compression springs 502 are connected to the bottom of the placement opening 204, so the up and down movement position of the L-shaped plate 5 is restricted. Connecting shafts 203 are fixed to the outer corners of the left and right sides of the upper end of the housing 2. Rotating cylinders 602 are fixed to the opposite lower side diagonals of the two baffles 6, and the rotating cylinders 602 are rotatably sleeved on the outer side wall of the connecting shaft 203. When the baffle 6 rotates, the baffle 6 will rotate on the outer side of the connecting shaft 203 through the rotating cylinder 602. A zigzag plate 4 is arranged inside the adjustment opening 208 above the adjustment plate 3. Pulley 402 is rotatably connected to both the front and rear sides of the zigzag plate 4, and the pulley 402 is in contact with the side wall of the adjustment opening 208; Strip plates 401 are arranged at the front and rear portions above the zigzag plate 4, and both ends of the strip plate 401 are fixedly connected to the left and right side walls of the adjustment opening 208. Limiting springs 403 are fixed between the strip plate 401 and the zigzag plate 4. When the adjustment plate 3 rotates, the roller 305 or the semi-circular clamping cylinder 301 on the adjustment plate 3 will contact the bottom of the zigzag plate 4. Then, the roller 305 or the semi-circular clamping cylinder 301 will push the zigzag plate 4 upward, thereby squeezing the limiting spring 403. At the same time, when the zigzag plate 4 moves up and down, it will drive the pulley 402 to slide on the side wall of the adjustment opening 208. After the position of the adjustment plate 3 is rotated, the zigzag plate 4 is pushed by the limiting spring 403 to press the roller 305 or the semi-circular clamping cylinder 301, improving the position stability of the roller 305 and the semi-circular clamping cylinder 301.

[0051] The above are only the preferred embodiments of the present invention and do not limit the present invention. Any modification of the technical solutions recorded in the foregoing embodiments, any equivalent replacement of some technical features, and any modification, equivalent replacement, and improvement made shall fall within the protection scope of the present invention.
