[0038] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0039] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0040] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0041] Most existing non-invasive ventilators lack dedicated placement devices for face masks or nasal masks, forcing patients to place them anywhere after removal, increasing the risk of them falling out and becoming contaminated. While some existing non-invasive ventilators have mask placement devices, these are only for securing the mask body and are only compatible with one type of mask. In reality, because different masks vary in price but have similar practical uses, a single non-invasive ventilator may be equipped with masks from different manufacturers and models.

[0042] A face mask (nasal mask) includes a mask body and an L-shaped tube connected to the mask body, or a T-shaped forehead pad connected to part of the mask body. Different models of face masks have different sizes of mask bodies, while the size and structure of the L-shaped tube and the T-shaped forehead pad are consistent. The difference between a face mask and a nasal mask lies in the size of the mask body; a face mask is used to cover a person's mouth and nose, while a nasal mask is only used to cover a person's nose. This application takes the fact that the structure and size of the L-shaped tube and the T-shaped forehead pad of different models of face masks are basically the same as those of other models, and designs a placement device specifically for fixing the L-shaped tube or the T-shaped forehead pad, thus realizing a placement device that can hold and fix face masks of different manufacturers and models.

[0043] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0044] Please refer to Figures 1 to 5 One embodiment provides a ventilator cart for placing a non-invasive ventilator and its related components. The ventilator cart mainly includes a cart body 10 and a respiratory accessory placement device 20. The respiratory accessory placement device 20 is installed on the upper end of the cart body 10 and is used to place respiratory accessories 30. The respiratory accessory 30 is a face mask or nasal mask. Both face masks and nasal masks include a mask body 31 and a tube 32. The mask body 31 is used to cover the mouth and nose of the human body. The tube 32 is connected to the mask body 31, and the connection between the tube 32 and the mask body 31 is an L-shaped structure. The tube 32 and the mask body 31 are either an integrated structure, with the tube 32 used to connect to the trachea, or the tube 32 and the mask body 31 are detachable, with the tube 32 being part of the trachea.

[0045] Specifically, a handle 11 is installed at the upper end of the vehicle body 10, wrapping around the upper part of the vehicle body 10. The handle 11 is used to assist doctors in pushing the ventilator cart. Casters 12 are installed at the lower end of the vehicle body 10, assisting the ventilator cart in movement. A notch is provided on the rear side of the handle 11, dividing the rear side of the handle 11 into two L-shaped sections. Cables can be wound around the L-shaped handle 11 through the notch, making it convenient for doctors to store cables. A bracket 13 is also installed on the vehicle body 10, which is used to suspend the endotracheal tube and cables.

[0046] The breathing accessory placement device 20 includes a connecting portion 21 and a snap-fit ​​portion 22. One end of the connecting portion 21 is mounted on the left side of the handle 11 by a screw or snap-fit. The connecting portion 21 can also be mounted on the right side of the handle 11. There are two snap-fit ​​portions 22, mounted on the end of the connecting portion 21 away from the handle 11, and the two snap-fit ​​portions 22 are positioned upwards and spaced apart, forming a notch 221 between them. The connecting portion 21 and the snap-fit ​​portion 22 are an integral structure, with the snap-fit ​​portion 22 extending upwards from the end of the connecting portion 21.

[0047] The connecting part 21 supports the cover 31 of the breathing accessory 30. The width of the latch 221 is slightly larger than the outer diameter of the tube 32 of the breathing accessory 30, so that the tube 32 of the breathing accessory 30 can be inserted into the latch 221 from top to bottom. The locking part 22 is used to block the back of the cover 31 of the breathing accessory 30 (the side of the cover 31 facing the human body is the front), and the locking part 22 can prevent the cover 31 from slipping off.

[0048] The upper surface of the connecting part 21 is provided with an arc-shaped groove 211. The groove 211 is adapted to the bottom of the cover 31, so that when the cover 31 is placed, its bottom can be inserted into the groove 211, further limiting the cover 31 and thus improving the stability of placing the breathing accessory 30.

[0049] The two snap-fit ​​parts 22 have symmetrical concave arc surfaces on the surfaces facing the connecting part 21. The concave arc surfaces of the two snap-fit ​​parts 22 are adapted to the back of the cover 31, so that when the breathing accessory 30 is placed, the back of the cover 31 can abut against the concave arc surfaces of the two snap-fit ​​parts 22, increasing the limiting area of ​​the cover 31 and thus improving the stability of placing the breathing accessory 30.

[0050] The ventilator trolley provided in this embodiment has a respiratory accessory placement device 20 on the upper side of the trolley body 10. The respiratory accessory placement device 20 has two snap-fit ​​parts 22 and one connecting part 21. A bayonet 221 is formed between the two snap-fit ​​parts 22. The bayonet 221 can be used to snap the tubing 32 on the respiratory accessory 30. The connecting part 21 can be used to support the respiratory accessory 30, so that the respiratory accessory placement device 20 can partially fix the L-shaped tubing on the respiratory accessory 30. The structure of the L-shaped tubing 32 on respiratory accessories 30 from different manufacturers and models is the same. Therefore, the respiratory accessory placement device 20 on this ventilator trolley can place respiratory accessories 30 from different manufacturers and models, and can prevent the respiratory accessories 30 from falling off and becoming contaminated.

[0051] The respiratory accessory placement device 20 of this embodiment has a groove 211 and a concave arc surface for supporting the respiratory accessory 30, which can serve as an identifier. Doctors can immediately identify that the respiratory accessory placement device 20 is used to place the respiratory accessory 30. Therefore, the respiratory accessory placement device 20 also guides doctors or patients to place the respiratory accessory 30 on it, thereby reducing the misplacement of the respiratory accessory 30.

[0052] In other embodiments, a label for placing the breathing accessory 30 is sprayed or pasted on or near the breathing accessory placement device 20, or the breathing accessory placement device 20 is set to a special color to further serve as a label and guide for placement.

[0053] Please refer to Figure 4and Figure 5 , Figure 4 The breathing accessory 30 in the picture is a face mask. Figure 5 The breathing accessory 30 is a nasal mask. The nasal mask body 31 is smaller than the face mask body 31. The tubes 32 of the face mask and the nasal mask have the same installation position and structure. Since the breathing accessory placement device 20 mainly uses the snap-fit ​​part 22 to limit the tubes 32 to fix the breathing accessory 30, both face masks and nasal masks with the same tubes 32 can be placed on the breathing accessory placement device 20.

[0054] Please refer to Figures 6 to 9 One embodiment provides a ventilator cart, which differs from the ventilator cart of the above embodiments in the structure of the respiratory accessory placement device. In this embodiment, the respiratory accessory placement device 40 is used to suspend the respiratory accessory 30, which is connected to a T-shaped forehead pad.

[0055] The respiratory accessory placement device 40 of this embodiment includes a connecting portion 41 and a snap-fit ​​portion 42. One end of the connecting portion 41 is mounted on the left side of the handle 11 by a screw or snap-fit. The connecting portion 41 can also be mounted on the right side of the handle 11. There are two snap-fit ​​portions 42, which are mounted on the end of the connecting portion 41 away from the handle 11. The two snap-fit ​​portions 42 are arranged upward and spaced apart, forming a notch 421 between them. The connecting portion 41 and the snap-fit ​​portion 42 are an integral structure, with the snap-fit ​​portion 42 extending upward from the end of the connecting portion 41.

[0056] The breathing accessory 30 includes a mask 31, a tube 32, and a T-shaped forehead pad 33. The tube 32 is connected to the lower end of the back of the mask 31, and the T-shaped forehead pad 33 is connected to the upper end of the front of the mask 31.

[0057] The latch 421 is used to engage the T-shaped forehead pad 33. The T-shaped forehead pad 33 has a horizontal strip 331 and a vertical strip 332. One end of the vertical strip 332 is connected to the upper end of the cover 31, and the other end of the vertical strip 332 is perpendicularly connected to the middle of the horizontal strip 331. When the breathing accessory 30 is placed, the vertical strip 332 of the T-shaped forehead pad 33 passes through the latch 421, and the horizontal strip 331 of the T-shaped forehead pad 33 is positioned on the two engaging parts 42. The breathing accessory 30 is suspended on the breathing accessory placement device 40 under its own weight.

[0058] In this embodiment, the ventilator trolley has a respiratory accessory placement device 40 for suspending the T-shaped forehead pad 33 of the respiratory accessory 30. The structure and size of the T-shaped forehead pad 33 of the respiratory accessory 30 from different manufacturers and models are basically the same, so the ventilator trolley can place respiratory accessories 30 from different manufacturers and models.

[0059] Please refer to Figures 10 to 12One embodiment describes a ventilator cart, which differs from the ventilator cart in the above embodiment in the structure of its respiratory accessory placement device. In this embodiment, the respiratory accessory placement device 40 is used to engage the tubing 32 on the respiratory accessory 30.

[0060] The respiratory accessory placement device 50 of this embodiment includes a connecting portion 51 and a snap-fit ​​portion 52. One end of the connecting portion 51 is mounted on the left side of the handle 11 by a screw or snap-fit. The connecting portion 51 can also be mounted on the right side of the handle 11. There are two snap-fit ​​portions 52, mounted on the end of the connecting portion 51 away from the handle 11, and horizontally spaced apart, forming a circular notch 521 between them. The connecting portion 51 and the snap-fit ​​portion 52 are an integrated structure, with the snap-fit ​​portion 52 extending horizontally from the end of the connecting portion 51. Of course, in other embodiments, the connecting portion 51 and the snap-fit ​​portion 52 are two separate parts fixedly connected together.

[0061] The snap-fit ​​part 52 is an elastic component made of elastic plastic. When there is no external force, the inner diameter of the snap-fit ​​opening 521 formed by the two snap-fit ​​parts 52 is slightly smaller than the outer diameter of the pipe 32. The snap-fit ​​opening 521 is used to snap the pipe 32.

[0062] When the breathing accessory 30 is placed and fixed, the vertical part of the tube 32 is squeezed into the bayonet 521, and the breathing accessory 30 is fixed by the elastic force of the bayonet 521.

[0063] In this embodiment, the ventilator trolley has a bayonet 521 on the respiratory accessory placement device 40 that can elastically engage the pipe 32 of the respiratory accessory 30. The pipe 32 of respiratory accessories 30 from different manufacturers and models has a basically the same structure and size, so the ventilator trolley can hold respiratory accessories 30 from different manufacturers and models.

[0064] Please refer to Figure 13 and Figure 14 One embodiment provides a ventilator cart, which is equipped with a handle. The handle can not only be used to assist doctors in pushing the ventilator cart, but also to facilitate the storage of cables.

[0065] In this embodiment, a handle 11 is installed at the upper end of the vehicle body 10, and the handle 11 wraps around the upper end of the vehicle body 10. The handle 11 is used to assist the doctor in pushing the ventilator cart. Casters 12 are installed at the lower end of the vehicle body 10, and the casters 12 assist the ventilator cart in moving. A notch 111 is provided on the rear side of the handle 11, which divides the rear side of the handle 11 into two L-shaped structures. The cable 60 can be wound around the L-shaped handle 11 through the notch 111, which facilitates the doctor in storing the cable 60.

[0066] In this embodiment, the handle 11 is an open handle. Compared with the closed handles in the prior art, the handle 11 in this embodiment has a notch 111, allowing the doctor to hang the cable 60 on the handle 11 with one hand. In the prior art, the doctor needs to use two hands to wrap the cable 60 around the handle 11. Therefore, the handle 11 in this embodiment can greatly facilitate the doctor in storing the cable 60.

[0067] Please refer to Figure 15 One embodiment provides a ventilator. In addition to the ventilator cart 100 described in any of the above embodiments, taking the first embodiment as an example, the ventilator also includes a display 200, a main unit 300, a humidifier 400, and a trachea.
