[0030] The utility model will be further described below in combination with the drawings.

[0031] According to the first aspect of the utility model, like Figures 1-4As shown, the utility model provides a kind of multifunctional joint 1 for ventilation therapy equipment, and the ventilation therapy equipment of the utility model can be, for example, breathing machine or high flow humidification oxygen therapy instrument.The multifunctional joint 1 of the utility model can carry out pressure detection and calibration, sealing detection and calibration and flow detection and calibration and other functions such as multiple function test to ventilation therapy equipment 2.

[0032] Specifically, as shown in Figure 1 And Figure 4 The multifunctional joint 1 for ventilation therapy equipment includes air inlet joint 11, air outlet joint 12 and pressure joint, wherein air inlet joint 11 is configured to be matched with the outer diameter of air inlet 21 of ventilation therapy equipment 2, so as to be inserted into air inlet 21 to block air inlet 21.For example, the outer diameter of air inlet joint 11 can be 22mm, that is, the same as (or slightly smaller than) the inner diameter of air inlet 21 of ventilation therapy equipment 2, so that air inlet joint 11 can be inserted into air inlet 21 of ventilation therapy equipment 2 to block air inlet 21.

[0033] As can be understood, when air inlet joint 11 is inserted into air inlet 21 of ventilation therapy equipment 2, air inlet 21 of ventilation therapy equipment 2 is blocked, and air cannot enter from air inlet 21.

[0034] Alternatively, air inlet joint 11 can also be configured to be matched with the inner diameter of air inlet 21 of ventilation therapy equipment 2, that is, air inlet 21 of ventilation therapy equipment 2 can be inserted into air inlet joint 11.For example, the inner diameter of air inlet joint 11 can be 22mm, that is, the same as (or slightly larger than) the outer diameter of air inlet 21 of ventilation therapy equipment 2, so that air inlet joint 11 can accommodate air inlet 21 of ventilation therapy equipment 2 to block air inlet 21.

[0035] Air outlet joint 12 is connected with air inlet joint 11, and accommodating cavity 13 is arranged on the side of air outlet joint 12 away from air inlet joint 11, and accommodating cavity 13 is configured to be matched with the inner diameter of air outlet 22 of ventilation therapy equipment 2, so as to accommodate air outlet 22 and be in fluid communication with air outlet 22.For example, the inner diameter of accommodating cavity 13 can be 22mm, that is, the same as (or slightly larger than) the outer diameter of air outlet 22 of ventilation therapy equipment 2, so that air outlet 22 of ventilation therapy equipment 2 can be inserted into accommodating cavity 13, and the fluid in air outlet 22 can enter accommodating cavity 13.

[0036] Alternatively, the receiving cavity 13 is configured to have an outer diameter that is adapted to the gas outlet 22 of the ventilation therapy device 2, so that the receiving cavity 13 can be inserted into the gas outlet 22 and be in fluid communication with the gas outlet 22. For example, the receiving cavity 13 can have an outer diameter of 22 mm, i.e. the same as (or slightly smaller than) the inner diameter of the gas outlet 22 of the ventilation therapy device 2, so that the receiving cavity 13 can be inserted into the gas outlet 22 of the ventilation therapy device 2, and the fluid in the gas outlet 22 can enter the receiving cavity 13.

[0037] As shown in Figure 2 , Figure 3 and Figure 4 , the pressure connector 14 is located on the gas inlet connector 11 or the gas outlet connector 12 and is in fluid communication with the receiving cavity 13, and the pressure connector 14 can be connected to the proximal pressure interface 27 (see Figure 8 ) of the ventilation therapy device 2, so as to detect and calibrate whether the proximal pressure of the ventilation therapy device 2 is accurate. The pressure connector 14 can be in fluid communication with the proximal pressure interface 27 of the ventilation therapy device 2 through a pipe such as a hose, so as to block the proximal pressure interface 27, so as to detect and calibrate the proximal pressure sensor.

[0038] In use, the proximal pressure interface of the ventilation therapy device 2 is used to connect a patient interface (such as a breathing mask) to measure the pressure in the patient interface.

[0039] As shown in Figure 4 , the pressure connector 14 is located on the gas inlet connector 11, and since the outer diameter of the gas inlet connector 11 is smaller than that of the gas outlet connector 12, arranging the pressure connector 14 on the gas inlet connector 11 is beneficial to reduce the overall volume of the multifunctional connector 1 for the ventilation therapy device.

[0040] When detecting and calibrating the ventilation therapy device 2 (generally before the ventilation therapy device 2 is turned on for treatment), whether the air inlet blockage alarm function of the ventilation therapy device 2 meets the requirements can be tested by inserting the gas inlet connector 11 into the air inlet 21 of the ventilation therapy device 2 (see Figure 8 ). For example, if the ventilation therapy device 2 prompts the alarm information of the air inlet 21 blockage after the air inlet 21 of the ventilation therapy device 2 is blocked, it indicates that the air inlet blockage alarm function of the ventilation therapy device 2 meets the requirements; otherwise, it indicates that the air inlet blockage alarm function of the ventilation therapy device 2 does not meet the requirements.

[0041] Alternatively, whether the air outlet blockage alarm function of the ventilation therapy device 2 meets the requirements can be tested by inserting the gas outlet connector 12 into the gas outlet 22 of the ventilation therapy device 2 (see Figure 6) to test whether the overall sealing of the ventilation therapy device 2 meets the requirements. For example, when the gas outlet 22 of the ventilation therapy device 2 is connected with the gas outlet connector 12, and the pressure connector 14 is further connected with the proximal pressure interface 27 through a hose, it can be understood that at this time the outlet of the ventilation therapy device 2 for outputting gas to the outside is completely blocked, and thus the fluid pressure at the gas outlet 22 and the fluid pressure at the proximal pressure interface 27 can be detected by the pressure detection device (for example, the main gas flow pressure sensor and the proximal pressure sensor) built in the main machine 23 of the ventilation therapy device 2, and if the two are equal and meet the expected pressure, it indicates that the overall sealing of the ventilation therapy device 2 meets the requirements; otherwise, it indicates that the overall sealing of the ventilation therapy device 2 does not meet the requirements.

[0042] Or the proximal pressure of the ventilation therapy device 2 can be tested by inserting the gas outlet connector 12 into the gas outlet 22 of the ventilation therapy device 2 and blocking the proximal pressure interface 27 with the pressure connector 14. For example, the gas outlet 22 and the proximal pressure interface 27 of the ventilation therapy device 2 are connected with the gas outlet connector 12 and the pressure connector 14 respectively, and the fluid pressure at the proximal pressure interface 27 can be detected by the proximal pressure sensor built in the main machine 23 of the ventilation therapy device 2, and if the detected fluid pressure meets the expected pressure, it indicates that the proximal pressure of the ventilation therapy device 2 is accurate; otherwise, if there is a difference between the detected fluid pressure and the expected pressure, and the difference is obviously not caused by air leakage, it indicates that the proximal pressure sensor of the ventilation therapy device 2 may be abnormal.

[0043] Further, as shown in Figure 4 , the gas inlet connector 11 is in fluid communication with the containing cavity 13, and the end of the gas inlet connector 11 away from the gas outlet connector 12 is a closed end. Since one end of the gas inlet connector 11 is a closed end, the gas inlet connector 11 will not be in fluid communication with the gas inlet 21 when it is inserted into the gas inlet 21. And since the containing cavity 13 is in fluid communication with the gas inlet connector 11, for example, the containing cavity 13 can further extend into the gas inlet 21, thereby reducing the wall thickness of the gas inlet connector 11 to reduce manufacturing costs.

[0044] As shown in Figure 4 , the gas inlet connector 11 is configured as a tapered structure with a gradually decreasing outer diameter in the direction away from the gas outlet connector 12. Since the gas inlet connector 11 is a tapered structure, it is easier to insert at the beginning, and as the gas inlet connector 11 is inserted deeper into the gas inlet 21, the fit between the outer wall of the gas inlet connector 11 and the inner wall of the gas inlet 21 will be tighter, thereby ensuring that the gas inlet connector 11 can sealably block the gas inlet 21.

[0045] It is conceived that the outer wall of the air inlet joint 11 can also be provided with a convex structure extending in the axial direction in the form of a thread, or the outer wall of the air inlet joint 11 can also be provided with a convex structure in the form of a pagoda structure, both of which can play the role of a sealing strip to ensure the sealed connection between the air inlet joint 11 and the air inlet 21.

[0046] As shown in Figure 4 , the accommodation cavity 13 is configured as a conical cavity structure with a gradually decreasing inner diameter in the direction close to the air inlet joint 11. Since the accommodation cavity 13 is a conical cavity structure, it is relatively easy when the air outlet 22 is just inserted into the accommodation cavity 13; as the air outlet 22 is inserted deeper into the accommodation cavity 13, the fit between the outer wall of the air outlet 22 and the inner wall of the accommodation cavity 13 will be tighter, thereby ensuring that the accommodation cavity 13 and the air outlet 22 form a fluid-tight connection.

[0047] It is conceived that the inner wall of the accommodation cavity 13 can also be provided with a convex structure extending in the axial direction in the form of a thread, which can play the role of a sealing strip to ensure the fluid seal between the accommodation cavity 13 and the air outlet 22.

[0048] The air inlet joint 11 and the air outlet joint 12 are of an integrated structure, and the accommodation cavity 13 extends into the air inlet joint 11. The air inlet joint 11 and the air outlet joint 12 can be integrally formed, for example, by plastic forming or the like, so as to quickly produce and manufacture the multifunctional joint 1 for the ventilation therapy device. In addition, the accommodation cavity 13 can be formed by opening or slotting from one end of the air outlet joint 12, or the accommodation cavity 13 can be integrally formed with the air inlet joint 11 and the air outlet joint 12.

[0049] As shown in Figure 2 , Figure 3 and Figure 4 , the multifunctional joint 1 for the ventilation therapy device further includes a flow joint 15, which is located on the air inlet joint 11 or the air outlet joint 12 and is in fluid communication with the accommodation cavity 13. The flow joint 15 can detect and calibrate whether the flow monitoring device (such as a flow sensor) of the ventilation therapy device 2 is abnormal.

[0050] Specifically, when the multifunctional joint is connected to the gas outlet, the gas path in the ventilation therapy device 2 is in a blocked state, at this time, the gas path in the ventilation therapy device 2 has no gas flow, and the flow cannot be detected. When it is necessary to detect and calibrate the flow sensor, it is necessary to open the flow joint 15, at this time, the gas path in the ventilation therapy device 2 has gas passing through, and the flow monitoring device in the ventilation therapy device 2 can detect the flow. Since the rotation speed of the fan assembly of the ventilation therapy device 2 corresponds to the expected flow (under the condition that the gas flow rate of the gas inlet 21 is constant), if the flow detected by the flow monitoring device of the ventilation therapy device 2 at this time does not match the expected flow, it indicates that the flow monitoring device is abnormal.

[0051] As shown in Figure 4 , the flow joint 15 is located on the gas inlet joint 11 and is arranged opposite to the pressure joint 14. Since the outer diameter of the gas inlet joint 11 is smaller than the outer diameter of the gas outlet joint 12, arranging the flow joint 15 on the gas inlet joint 11 is beneficial to reduce the overall volume of the multifunctional joint 1 for ventilation therapy devices.

[0052] In addition, the flow joint 15 is provided with a cover 16, which can block the flow joint 15 when covering the flow joint 15. When the cover 16 is removed, the flow joint 15 is opened. As shown in Figure 4 , the inner side of the cover 16 is provided with a plug 18. When the cover 16 covers the flow joint 15, the inner wall of the cover 16 is in contact with the outer wall of the flow joint 15, and the plug 18 is inserted into the flow joint 15, thereby blocking the flow joint 15.

[0053] The cover 16 is provided with a connecting part 17, which can be a silica gel strip or a plastic strip, etc. The cover 16 is connected to the gas inlet joint 11 or the gas outlet joint 12 through the connecting part 17. For example, when the flow joint 15 is located on the gas inlet joint 11, the cover 16 is connected to the outer wall of the gas inlet joint 11 through the connecting part 17. When the cover 16 is removed from the flow joint 15, the cover 16 is still connected to the gas inlet joint 11, thereby avoiding the possibility of the cover 16 being lost, etc.

[0054] According to the second aspect of the utility model, as shown in Figures 5-8 , the utility model provides a ventilation therapy device 2, which can be a respirator or a high-flow humidified oxygen therapy instrument. The ventilation therapy device 2 of the utility model comprises the multifunctional joint 1 for ventilation therapy devices described above, and further comprises a host 23. One side of the host 23 is provided with a gas outlet 22, and the other side of the host 23 is provided with a gas inlet 21. The gas inlet 21 and the gas outlet 22 are in fluid communication.

[0055] As shown in Figure 5 and Figure 8As shown, the left side of the host 23 is provided with an air outlet 22, which is used to provide ventilation gas into the patient interface; as Figure 8 As shown, the lower side of the air outlet 22 is provided with a proximal pressure interface 27. The proximal pressure interface 27 is used to connect with the patient interface when in use, so as to measure the pressure in the patient interface.

[0056] The rear side of the host 23 is provided with an air inlet 21, and the host 23 is also provided with a fan assembly. Air can enter the fan assembly from the air inlet 21 for pressure processing. The pressurized pressure gas can be provided to the patient interface from the air outlet 22 for the patient to breathe.

[0057] As shown in Figure 5 and Figure 6 The ventilation therapy device multifunctional joint 1 is connected with the air outlet 22 of the ventilation therapy device 2, which can calibrate the overall sealing of the ventilation therapy device 2, and also calibrate the proximal pressure of the ventilation therapy device 2.

[0058] As shown in Figure 7 and Figure 8 The ventilation therapy device multifunctional joint 1 blocks the air inlet 21 of the ventilation therapy device 2, which can test whether the air inlet blockage alarm function of the ventilation therapy device 2 meets the requirements.

[0059] In addition, as shown in Figure 7 One side of the host 23 is also provided with a receiving groove 24, and the ventilation therapy device multifunctional joint 1 is located in the receiving groove 24. When not calibrating, the ventilation therapy device multifunctional joint 1 can be clamped into the receiving groove 24, and when calibrating, it can be conveniently taken out from the receiving groove 24. For example, the receiving groove 24 is located on the rear side of the host 23, and a plurality of clamping grooves are arranged in the receiving groove, each clamping groove is clamped with one or more of the air inlet joint 11, the air outlet joint 12, the pressure joint 14 or the cover 16, so as to fix the ventilation therapy device multifunctional joint 1 in the receiving groove 24.

[0060] The inside of the host 23 is also provided with a pressure detection device (not shown), which includes a main gas path pressure sensor and a proximal pressure sensor. The main gas flow pressure sensor is used to indicate the pressure of the air outlet 22, and the proximal pressure sensor is used to indicate the pressure at the proximal pressure interface 27.

[0061] As shown in Figure 7 The front side of the host 23 is also provided with a display 25, which can display various parameters of the host 23. The right side of the display 25 is an operation button, such as a power-on button, a flow adjustment button, etc.

[0062] As shown in Figure 7As shown, the main machine 23 is also provided with a handle ring 26, and the main machine 23 can be conveniently carried and moved through the handle ring 26.

[0063] In addition, it needs to be explained that the ventilation therapy equipment of the utility model can also include various structures and components to realize its necessary functions, which can all select the structure form of known components.

[0064] Although the utility model has been described with reference to the preferred embodiments, various improvements can be made and the components therein can be replaced with equivalents without departing from the scope of the utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
