Description

Technical Field

[0001] This utility model relates to the field of ventilator technology, and in particular to a portable ventilator casing. Background Technology

[0002] A ventilator is an important medical device that helps or replaces a patient's breathing by delivering pressurized oxygen or other mixed gases to the patient's lungs to maintain or improve their respiratory function. It is widely used in hospitals, emergency care, and home care. A portable ventilator is a cleverly designed, lightweight and easy-to-carry medical device designed specifically for patients who need respiratory assistance. It can provide continuous and stable respiratory support in various environments, greatly facilitating patients' lives and travel.

[0003] Currently, while existing ventilator casings offer some protection and ease of disassembly, they cannot flexibly adjust the ventilator's operating angle, making it difficult for users to achieve optimal comfort and convenience. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot flexibly adjust the angle of use of the ventilator, making it difficult for users to obtain optimal comfort and convenience during use, and to propose a portable ventilator shell.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A portable ventilator casing, comprising:

[0007] The base, upper shell, and lower shell are connected by four bolts in a rectangular shape between the upper shell and the lower shell. The bottom ends of the four bolts are all connected to the internal threads of the lower shell.

[0008] An adjustment mechanism is located on the base and the lower housing and is used to adjust the operating angle of the ventilator.

[0009] The support assembly is mounted on the base and the lower housing and is used to support the adjustment angle of the ventilator.

[0010] In one possible design, the adjustment mechanism includes ring-shaped toothed grooves on both sides of the lower housing. Bolts are inserted through both sides of the base. The ends of the two bolts that are close to each other are threaded to the two sides of the lower housing. Springs are sleeved on the outside of the two bolts. Gear discs are slidably arranged on the outside of the two bolts. One end of the spring is fixedly connected to one side of the bolt, and the other end of the spring abuts against the gear disc. The gear disc is adapted to the toothed grooves and can be disengaged.

[0011] In one possible design, the support assembly includes two cavities respectively opened on both sides of the base. The top two sides of the base are provided with through slots communicating with the cavities. The bottom walls of the two cavities are fixedly provided with racks. The bottom two sides of the lower housing are fixedly provided with fixing seats. The inner sides of the two fixing seats are rotatably provided with support rods. The two support rods pass through the through slots and extend into the cavities. The ends of the two support rods located inside the cavities are fixedly provided with locking blocks. The locking blocks are adapted to the racks and can be disengaged and engaged.

[0012] In one possible design, the lower housing and the upper housing have the same display screen placement opening on their front sides. The upper housing has two pipe penetration holes on both sides of the display screen placement opening. The lower housing has two symmetrical ventilation holes on its rear side. Filters are fixedly installed on the inner side of the lower housing at both ventilation holes.

[0013] In one possible design, two hanging brackets are rotatably provided on both sides of the lower housing for easy attachment of the shoulder strap, and a handle is fixedly provided on the top of the upper housing.

[0014] In one possible design, edge banding strips are fixedly provided at the four corners of both the lower and upper shells.

[0015] In one possible design, a bracket is fixedly provided on the top of the lower housing, and a slot for inserting the bracket is provided on the bottom of the upper housing.

[0016] In this application, when starting to use the device, first place the base plate and the lower housing on it on a stable workbench. Then, install all the internal components of the ventilator into the lower housing in their corresponding positions. Align the display screen with the display screen placement opening and install it. Then, pass the pipes that need to extend outside the housing through the pipe through holes. After all the components are installed and arranged, take out the upper housing and align the bottom slot of the upper housing with the top insertion of the lower housing. Then, press down on the upper housing to splice the upper and lower housings to complete the initial installation. Then, pass four bolts through the top of the upper housing and extend into the interior of the lower housing. Then, use tools to connect the four bolts to the internal threads of the lower housing in sequence to complete the installation and fixation between the upper and lower housings.

[0017] When adjusting the operating angle of the ventilator, press down on the base and lift the lower housing upwards, causing the lower housing to rise in a fan shape along the hinge of the base. As the lower housing rises, the toothed grooves on both sides rotate. As the toothed grooves rotate, they intersect with the toothed disc, causing the toothed disc to disengage from the toothed grooves. The intersecting toothed discs exert a backward thrust, compressing the spring. When the teeth and grooves between the toothed disc and the toothed groove are aligned, the spring pushes the toothed disc to engage with the toothed groove. Continue lifting the lower housing using the above principle until the optimal operating angle is reached. Stop lifting the lower housing. At this point, the spring has pushed the toothed disc to engage with the toothed groove, thus initially defining the operating position of the ventilator.

[0018] During the lifting of the lower housing, the support rods on both sides rotate inside the fixed base, causing the two support rods to move in the direction of the slot. As the support rods move, the locking block at the bottom moves on the rack inside the cavity. When the lower housing is lifted to the appropriate position, the support rods stop moving. At this time, the locking block at one end of the support rod stops moving on the rack. When the locking block stops moving, it will lock into the slot of the rack due to its own inertia, thereby supporting and limiting the position of the ventilator.

[0019] This utility model has the following beneficial effects:

[0020] The present invention enables precise adjustment of the ventilator's operating angle through the setting of the adjustment mechanism, meeting the personalized needs of different users and improving the flexibility and comfort of use.

[0021] The present invention effectively supports and fixes the adjusted angle of the ventilator by setting up a support component, ensuring the stability and safety of use, and further improving the portability and practicality of the ventilator.

[0022] This invention, through the coordinated arrangement of the adjustment mechanism and support components, not only enables flexible adjustment of the ventilator's operating angle but also ensures stable support after adjustment, thereby improving the ventilator's practicality and user experience.
