DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] A. In a possible embodiment, Figures 1 to 12 As shown, an embodiment of the present invention provides a medical ventilation device 100 , which includes a housing assembly 10 , a turbine assembly 20 , an oxygen interface assembly 30 , an oxygen control assembly 40 and a gas output assembly 50 .

[0052] The housing assembly 10 includes a panel 11, a back panel 12, a top panel 13, a bottom panel 14, a first side panel 15, and a second side panel 16. The panel 11 is arranged opposite to the back panel 12, the top panel 13 is arranged opposite to the bottom panel 14, and the second side panel 16 is arranged opposite to the first side panel 15. It should be noted that the panel 11, the back panel 12, the top panel 13, the bottom panel 14, the second side panel 16, and the first side panel 15 are for the orientation of the medical ventilation device 100 in a normal use state, wherein the second side panel 16 is a panel located on the right side of the panel 11 when the operator faces the panel 11, and the first side panel 15 is a panel located on the left side of the panel 11 when the operator faces the panel 11.

[0053] The turbine assembly 20 is disposed inside the housing assembly 10 .

[0054] The oxygen interface assembly 30 is connected to the housing assembly 10, and the oxygen interface assembly 30 is used to connect an oxygen supply device. The oxygen supply device can be an oxygen cylinder or an oxygen concentrator, which can be determined according to actual design requirements.

[0055] The oxygen control assembly 40 is in communication with the oxygen interface assembly 30 to input the oxygen provided by the oxygen interface assembly 30, and the oxygen control assembly 40 is in communication with the turbine assembly 20 to output the oxygen to the turbine assembly 20. That is, the oxygen supplied by the oxygen supply device flows into the oxygen interface assembly 30, flows to the oxygen control assembly 40, and then flows from the oxygen control assembly 40 to the turbine assembly 20.

[0056] The gas output assembly 50 is connected to the housing assembly 10, and the gas output assembly 50 is in communication with the turbine assembly 20. The gas output assembly 50 is used to receive the gas output by the turbine assembly 20, and is used to connect the pipeline for delivering gas to the patient. That is, oxygen flows from the oxygen control assembly 40 to the turbine assembly 20 and mixes with the air entering the turbine assembly 20, and the mixed gas is sequentially delivered to the patient through the gas output assembly 50 and the pipeline for delivering gas to the patient.

[0057] The bottom plate 14 is divided into a first area S1, a second area S2, a third area S3 and a fourth area S4. The first area S1 is diagonally arranged with the fourth area S4, the second area S2 is diagonally arranged with the third area S3, the first area S1 is close to the back plate 12 and the first side plate 15, the second area S2 is close to the back plate 12 and the second side plate 16, the third area S3 is close to the panel 11 and the first side plate 15, and the fourth area S4 is close to the panel 11 and the second side plate 16. Among them, the projection of the turbine assembly 20 on the bottom plate 14 is located in the third area S3. The projection of the oxygen interface assembly 30 on the bottom plate 14 is located in the first area S1. The projection of the oxygen control assembly 40 on the bottom plate 14 is located in the second area S2 and the fourth area S4. The projection of the gas output assembly 50 on the bottom plate 14 is located in the fourth area S4. The projection of the oxygen control component 40 on the bottom plate 14 is located in the second area S2 and the fourth area S4, which means that the projection of the oxygen control component 40 on the bottom plate 14 is partially located in the second area S2 and partially located in the fourth area S4.

[0058] In the existing medical ventilation device 100, there are three arrangements of the oxygen control assembly 40. The oxygen control assembly 40 and the oxygen interface assembly 30 are designed as one body. One arrangement is to arrange the oxygen control assembly 40 and the oxygen interface assembly 30 together between the first side plate 15 and the turbine assembly 20. This embodiment requires that the spacing between the turbine assembly 20 and the first side plate 15 needs to be set larger to accommodate the oxygen control assembly 40, resulting in a longer overall length of the medical ventilation device 100. Another arrangement is to arrange the oxygen control assembly 40 and the oxygen interface assembly 30 together between the back plate 12 and the turbine assembly 20. This embodiment requires that the spacing between the turbine assembly 20 and the back plate 12 needs to be set larger to accommodate the oxygen control assembly 40, resulting in a wider overall width of the medical ventilation device 100. Another arrangement is to arrange the oxygen control assembly 40 and the oxygen interface assembly 30 together between the top plate 13 and the turbine assembly 20. This embodiment requires that the distance between the turbine assembly 20 and the top plate 13 or the bottom plate 14 be set larger to accommodate the oxygen control assembly 40, resulting in a higher overall height of the medical ventilation device 100. That is, the above three arrangements all make the overall size of the medical ventilation device 100 larger, which cannot meet the requirement of a smaller device size in emergency situations.

[0059] In this embodiment, after adopting the above technical solution, by setting the projection of the oxygen control assembly 40 on the bottom plate 14 to be located in the second area S2 and the fourth area S4, since the oxygen control assembly 40 is not in the first area S1, the distance between the turbine assembly 20 and the first side plate 15 can be set to be relatively small, and since the oxygen control assembly 40 is not entirely in the second area S2, the distance between the turbine assembly 20 and the back plate 12 can be set to be relatively small. When the oxygen control assembly 40 and the turbine assembly 20 have an overlapping portion in the height direction of the housing assembly 10, the distance between the turbine assembly 20 and the top plate 13 can also be set to be relatively small. In addition, the oxygen control assembly 40 and the gas output assembly 50 share the area between the turbine assembly 20 and the second side plate 16, so there is no need to expand the distance between the turbine assembly 20 and the second side plate 16. In this way, the entire medical ventilation device 100 can be reduced in length, width and height, so that the overall size of the medical ventilation device 100 is reduced, which can meet the requirements of small equipment size in emergency situations.

[0060] It should be noted that the projection of the oxygen control assembly 40 on the bottom plate 14 is not limited to being located in the second area S2 and the fourth area S4. For example, in another embodiment, Fig.13 As shown, the projection of the oxygen control assembly 40 on the bottom plate 14 is located in the fourth area S4. Fig.14As shown, the projection of the oxygen control assembly 40 on the bottom plate 14 is located in the third area S3 and the fourth area S4, that is, the projection of the oxygen control assembly 40 on the bottom plate 14 is partially located in the third area S3 and partially located in the fourth area S4. Fig.15 As shown, the projection of the oxygen control assembly 40 on the bottom plate 14 is located in the first area S1, the second area S2 and the fourth area S4, that is, the projection of the oxygen control assembly 40 on the bottom plate 14 is partially located in the first area S1, partially located in the second area S2, and partially located in the fourth area S4. It can be understood that in the above-mentioned several modified embodiments, even if the degree is different, the oxygen control assembly 40 can also play the effect of reducing the size of the medical ventilation device 100 when it is arranged in the above-mentioned several positions.

[0061] It should be noted that the projection of the turbine assembly 20 on the base plate 14 is located in the third area S3, which means that the projection of the entire turbine assembly 20 on the base plate 14 is located in the third area S3. The entire turbine assembly 20 includes the main body of the turbine assembly 20, which will be described in detail later.

[0062] It should be noted that the projection of the oxygen interface assembly 30 on the bottom plate 14 is not limited to being located in the first area S1. For example, in another embodiment, Fig.16 As shown, the projection of the oxygen interface assembly 30 on the bottom plate 14 is located in the third area S3. Fig.17 As shown, the projection of the oxygen interface assembly 30 on the bottom plate 14 is located in the first area S1 and the third area S3 , that is, the projection of the oxygen interface assembly 30 on the bottom plate 14 is partially located in the first area S1 and partially located in the third area S3 .

[0063] It should be noted that the projection of the gas output assembly 50 on the bottom plate 14 is not limited to being located in the fourth area S4. For example, in another embodiment, Fig.18 As shown, the projection of the gas output assembly 50 on the bottom plate 14 is located in the second area S2 and the fourth area S4, that is, the projection of the gas output assembly 50 on the bottom plate 14 is partially located in the second area S2 and partially located in the fourth area S4. Fig.19 As shown, the projection of the gas output assembly 50 on the bottom plate 14 is located in the third area S3 and the fourth area S4, that is, the projection of the gas output assembly 50 on the bottom plate 14 is partially located in the third area S3 and partially located in the fourth area S4.

[0064] In summary, in the embodiment of the present invention, the projection of the turbine assembly 20 on the bottom plate 14 is located in the third area S3. The projection of the oxygen interface assembly 30 on the bottom plate 14 is located in the first area S1, or in the third area S3, or in the first area S1 and the third area S3. The projection of the oxygen control assembly 40 on the bottom plate 14 is located in the fourth area S4, or in the second area S2 and the fourth area S4, or in the third area S3 and the fourth area S4, or in the first area S1, the second area S2 and the fourth area S4. The projection of the gas output assembly 50 on the bottom plate 14 is located in the fourth area S4, or in the second area S2 and the fourth area S4, or in the third area S3 and the fourth area S4. The oxygen control assembly 40 can reasonably utilize the area between the turbine assembly 20 and the second side plate 16, and the medical ventilation device 100 can be reduced in length, width and height, so that the overall size of the medical ventilation device 100 is small, which can meet the requirements of small equipment size in emergency situations.

[0065] like Fig.12 As shown, in one embodiment, the bottom plate 14 is divided into the first area S1, the second area S2, the third area S3 and the fourth area S4 by establishing a transverse axis X and a longitudinal axis Y on the bottom plate 14, wherein the transverse axis X extends along the length direction of the housing assembly 10, the projection of the turbine assembly 20 on the bottom plate 14 is located on the side of the transverse axis X close to the panel 11, the longitudinal axis Y extends along the width direction of the housing assembly 10, and the projection of the turbine assembly 20 on the bottom plate 14 is located on the side of the longitudinal axis Y close to the first side plate 15. The projection profile of the turbine assembly 20 on the bottom plate 14 includes a first vertex closest to the back plate 12 and a second vertex closest to the second side plate 16, the transverse axis X passes through the first vertex, and the longitudinal axis Y passes through the second vertex.

[0066] In one embodiment, the intersection of the horizontal axis X and the vertical axis Y is located in the middle area between the second side plate 16 and the first side plate 15. In one embodiment, the area between the second side plate 16 and the first side plate 15 is divided into five equal parts, and the middle part is the middle area.

[0067] B. In another possible embodiment, Figures 1 to 26 As shown, an embodiment of the present invention further provides a medical ventilation device 100 , which includes a housing assembly 10 , a turbine assembly 20 , an oxygen interface assembly 30 , an oxygen control assembly 40 and a gas output assembly 50 .

[0069] The turbine assembly 20 is disposed inside the housing assembly 10 .

[0070] The oxygen interface assembly 30 is connected to the housing assembly 10 , and the oxygen interface assembly 30 is used to connect to an oxygen supply device.

[0074] It should be noted that the area indicated by the side of the turbine assembly 20 toward the second side plate 16 refers to a vertical plane set with the rightmost point of the turbine assembly 20 as the base point, and the vertical plane extends to the top plate 13, bottom plate 14, panel 11 and back plate 12 of the shell assembly 10. The area between the vertical plane and the second side plate 16 is the area indicated by the side of the turbine assembly 20 toward the second side plate 16.

[0075] In this embodiment, the projection of the oxygen control component 40 on the second side plate 16 is arranged to at least partially overlap with the projection of the turbine component 20 on the second side plate 16, that is, the oxygen control component 40 is not entirely in the area between the turbine component 20 and the back plate 12, nor is it entirely in the area between the turbine component 20 and the top plate 13, and at least part of the oxygen control component 40 is located on the side of the turbine component 20 facing the second side plate 16, that is, the oxygen control component 40 is not in the area between the turbine component 20 and the first side plate 15. As described above, this embodiment allows the medical ventilation device 100 to be reduced in size in the length, width and height directions, so that the overall size of the medical ventilation device 100 is small, which can meet the requirements for a smaller device size in emergency situations.

[0076] Further, based on the possible embodiments described in A or B above, combined with the following Figure 3 and Figure 6-Figure 11 , Fig.23 , Fig.24As shown, in one embodiment, the turbine assembly 20 has a first inlet A1, a second inlet A2 and an outlet E2, and the first inlet A1 is used to input air. The oxygen control assembly 40 includes a first interface B1 and a second interface B2 connected to the first interface B1, and the second interface B2 is connected to the oxygen interface assembly 30 to input oxygen provided by the oxygen interface assembly 30.

[0078] In one embodiment, the oxygen control assembly 40 is used to monitor and / or adjust the oxygen flow rate. Optionally, the oxygen control assembly 40 includes a proportional valve and a first flow sensor, wherein the proportional valve is used to adjust the oxygen flow rate, and the first flow sensor is used to monitor the oxygen flow rate.

The pipe 60 can be, but is not limited to, a PU (polyurethane) pipe. It should be noted that the oxygen interface assembly 30 and the oxygen control assembly 40 are not limited to being arranged separately. For example, in some other embodiments, the oxygen interface assembly 30 and the oxygen control assembly 40 are integrally constructed.

[0081] In one embodiment, the medical ventilation device 100 further includes an oxygen monitoring module 70 , which is in communication with the gas output assembly 50 . The oxygen monitoring module 70 is used to detect the oxygen content in the gas outputted by the gas output assembly 50 .

In this embodiment, by arranging the portion of the oxygen interface assembly 30 exposed from the housing assembly 10 in the recessed portion 151, the oxygen interface assembly 30 can be hidden and protected. When the medical ventilation device 100 is accidentally dropped, the outer side wall of the housing assembly 10 will hit the ground first, thereby preventing the oxygen interface assembly 30 from being damaged by the impact, and at the same time, the size of the medical ventilation device 100 can be reduced.

[0085] In one embodiment, the first housing component 21 is separately provided from the housing component 10, and the first housing component 21 is connected to the bottom plate 14 or the back plate 12 or the first support component 80 through a mechanical structure. Of course, it is not limited to the above-mentioned embodiment.
