Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

A. In one possible embodiment, as shown in fig. 1-12, an embodiment of the present utility model proposes a medical ventilator 100, the proposed medical ventilator 100 comprising a housing assembly 10, a turbine assembly 20, an oxygen interface assembly 30, an oxygen control assembly 40, and a gas output assembly 50.

The housing assembly 10 includes a front 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, wherein the front panel 11 is disposed opposite the back panel 12, the top panel 13 is disposed opposite the bottom panel 14, and the second side panel 16 is disposed opposite the first side panel 15. 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 in terms of the orientation of the medical ventilator 100 in the normal use state, wherein the second side panel 16 is a panel body 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 body located on the left side of the panel 11 when the operator faces the panel 11.

The turbine assembly 20 is disposed within the housing assembly 10.

An oxygen interface assembly 30 is connected to the housing assembly 10, the oxygen interface assembly 30 being adapted to be connected to an oxygen supply. The oxygen supply device can be an oxygen bottle or an oxygenerator, and can be specifically determined according to actual design requirements.

Oxygen control assembly 40 communicates with oxygen interface assembly 30 to input oxygen provided via oxygen interface assembly 30, and oxygen control assembly 40 communicates with turbine assembly 20 to output oxygen to turbine assembly 20. That is, oxygen supplied from 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.

A gas output assembly 50 is coupled to the housing assembly 10, the gas output assembly 50 being in communication with the turbine assembly 20, the gas output assembly 50 being configured to receive the gas output by the turbine assembly 20 and to couple to a conduit for delivering the gas to a patient. That is, oxygen flows from the oxygen control assembly 40 to the turbine assembly 20 to mix with air entering the interior of the turbine assembly 20, and the mixed gas is delivered to the patient sequentially through the gas delivery assembly 50 and the tubing that delivers the gas to the patient.

The bottom plate 14 is divided into a first region S1, a second region S2, a third region S3 and a fourth region S4, the first region S1 is disposed diagonally to the fourth region S4, the second region S2 is disposed diagonally to the third region S3, the first region S1 is close to the back plate 12 and the first side plate 15, the second region S2 is close to the back plate 12 and the second side plate 16, the third region S3 is close to the face plate 11 and the first side plate 15, and the fourth region S4 is close to the face plate 11 and the second side plate 16. Wherein the projection of the turbine assembly 20 onto the bedplate 14 is located at a third area S3. The projection of the oxygen interface assembly 30 onto the base plate 14 is located in the first region S1. The projections of the oxygen control assembly 40 onto the base plate 14 are located in the second region S2 and the fourth region S4. The projection of the gas output assembly 50 onto the floor 14 is located in the fourth region S4. Wherein, the projection of the oxygen control assembly 40 on the base plate 14 is located in the second area S2 and the fourth area S4, which means that the projection of the oxygen control assembly 40 on the base plate 14 is partially located in the second area S2 and partially located in the fourth area S4.

In the existing medical ventilator 100, the oxygen control assembly 40 has three arrangements, namely, the oxygen control assembly 40 and the oxygen interface assembly 30 are integrally designed, wherein one arrangement is to arrange the oxygen control assembly 40 and the oxygen interface assembly 30 between the first side plate 15 and the turbine assembly 20, and the embodiment makes the interval between the turbine assembly 20 and the first side plate 15 needs to be set larger so as to accommodate the lower oxygen control assembly 40, which results in a longer overall length of the medical ventilator 100. Another arrangement is to arrange the oxygen control assembly 40 with the oxygen interface assembly 30 between the backplate 12 and the turbine assembly 20, which embodiment requires a larger spacing between the turbine assembly 20 and the backplate 12 to accommodate the lower oxygen control assembly 40, resulting in a wider overall width of the medical ventilator 100. Another arrangement is to arrange the oxygen control assembly 40 with the oxygen interface assembly 30 between the top plate 13 and the turbine assembly 20, which embodiment makes the spacing between the turbine assembly 20 and the top plate 13 or the bottom plate 14 to be set larger so as to accommodate the lower oxygen control assembly 40, resulting in a higher overall height of the medical ventilator 100. That is, the three arrangements mentioned above all make the overall size of the medical ventilation device 100 larger, and cannot meet the requirement of smaller device size in emergency situations.

In this embodiment, after the above technical solution is adopted, 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, because the oxygen control assembly 40 is not located in the first area S1, the interval between the turbine assembly 20 and the first side plate 15 may be set smaller, because the oxygen control assembly 40 is not all located in the second area S2, the interval between the turbine assembly 20 and the back plate 12 may be set smaller, and when the arrangement of the oxygen control assembly 40 and the turbine assembly 20 in the height direction of the housing assembly 10 has an overlapping portion, the interval between the turbine assembly 20 and the top plate 13 may also be set smaller. In addition, the oxygen control assembly 40 shares the area between the turbine assembly 20 and the second side plate 16 together with the gas output assembly 50, so that it is not necessary to enlarge the space between the turbine assembly 20 and the second side plate 16. Thus, the whole medical ventilation device 100 can be reduced in size in the length, width and height directions, so that the whole medical ventilation device 100 is reduced in size, and the requirement of the first-aid occasion on smaller device size can be met.

It should be noted that the projection of the oxygen control assembly 40 on the base plate 14 is not limited to be disposed in the second region S2 and the fourth region S4, for example, in another embodiment, as shown in fig. 13, the projection of the oxygen control assembly 40 on the base plate 14 is disposed in the fourth region S4. In another embodiment, as shown in fig. 14, the projection of the oxygen control assembly 40 on the base 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 base plate 14 is located in part in the third area S3 and in part in the fourth area S4. In another embodiment, as shown in fig. 15, the projection of the oxygen control assembly 40 on the base plate 14 is located in the first region S1, the second region S2 and the fourth region S4, i.e. the projection of the oxygen control assembly 40 on the base plate 14 is located in part in the first region S1, in part in the second region S2 and in part in the fourth region S4. It will be appreciated that in the several variant embodiments described above, the oxygen control assembly 40 may also have the effect of reducing the size of the medical ventilator 100 when arranged in the several positions described above, even to varying degrees.

It should be noted that, the projection of the turbine assembly 20 on the base plate 14 is located in the third area S3, and it is meant that the projection of the whole turbine assembly 20 on the base plate 14 is located in the third area S3, and the whole turbine assembly 20 includes the main body of the turbine assembly 20, which will be described later.

It should be noted that the projection of the oxygen interface assembly 30 on the base plate 14 is not limited to being disposed at the first area S1, for example, in another embodiment, as shown in fig. 16, the projection of the oxygen interface assembly 30 on the base plate 14 is disposed at the third area S3. In another embodiment, as shown in fig. 17, the projection of the oxygen interface assembly 30 on the base 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 base plate 14 is located in part in the first area S1 and in part in the third area S3.

It should be noted that, the projection of the gas output assembly 50 on the bottom plate 14 is not limited to being disposed at the fourth region S4, for example, in another embodiment, as shown in fig. 18, the projection of the gas output assembly 50 on the bottom plate 14 is located at the second region S2 and the fourth region S4, that is, the projection of the gas output assembly 50 on the bottom plate 14 is partially located at the second region S2 and partially located at the fourth region S4.

In summary, in the embodiment of the present utility model, the projection of the turbine assembly 20 onto the base plate 14 is disposed at the third area S3. The projection of the oxygen interface assembly 30 onto the base plate 14 is located in the first region S1, or in the third region S3, or in both the first region S1 and the third region S3. The projection of the oxygen control assembly 40 onto the base plate 14 is located in the fourth region S4, or in the second region S2 and the fourth region S4, or in the third region S3 and the fourth region S4, or in the first region S1, the second region S2 and the fourth region S4. The projection of the gas output assembly 50 onto the base plate 14 is located in the fourth region S4, or in the second and fourth regions S2 and S4, or in the third and fourth regions S3 and S4. The oxygen control assembly 40 may reasonably utilize the area between the turbine assembly 20 and the second side plate 16, and the medical ventilator 100 may be reduced in size in the length, width, and height directions, so that the overall size of the medical ventilator 100 is smaller, and the requirement of the emergency on smaller equipment size may be met.

As shown in fig. 12, in one embodiment, the base plate 14 is divided into the first region S1, the second region S2, the third region S3, and the fourth region S4 by establishing a horizontal axis X and a vertical axis Y on the base plate 14, wherein the horizontal axis X extends along the length direction of the housing assembly 10, a projection of the turbine assembly 20 on the base plate 14 is located on a side of the horizontal axis X near the panel 11, the vertical axis Y extends along the width direction of the housing assembly 10, and a projection of the turbine assembly 20 on the base plate 14 is located on a side of the vertical axis Y near the first side plate 15.
