Description

Technical Field

[0001] This utility model relates to the field of ventilation therapy technology, and in particular to a chassis structure and ventilation therapy device. Background Technology

[0002] Ventilation therapy equipment is suitable for patients with mild to moderate respiratory failure and respiratory insufficiency who do not require ventilatory support, providing them with ventilatory assistance and respiratory support. Ventilation therapy equipment generally includes important components such as noise reduction devices and control devices, as well as a housing that encloses these components. Therefore, there is an assembly relationship between these components and the housing; some control device interfaces even require mating with the housing to function. Consequently, performance testing of ventilation therapy equipment can generally only be conducted after all components and the housing have been assembled into a complete unit. If abnormalities are found during testing, the housing must be disassembled, and potentially faulty components must be inspected one by one. Only after troubleshooting and reassembly can testing be repeated, thus significantly impacting and slowing down the production efficiency of ventilation therapy equipment. Utility Model Content

[0061] The present invention will be further described below with reference to the accompanying drawings.

[0062] This utility model provides a chassis structure for a ventilation therapy device, wherein the ventilation therapy device can be a ventilator or a high-flow humidified oxygen therapy device. For example... Figures 1-16 As shown, the chassis structure of this utility model includes a chassis assembly 1 and a panel assembly 2 detachably connected to the chassis assembly 1. The chassis assembly 1 includes a noise reduction device 11, a control device 12, a battery device 13, and an interface device 14. The interface device 14 includes one or more of a mechanical interface, an electrical interface 144, and a fluid interface. The battery device 13 is connected to the fan assembly 1112 in the noise reduction device 11 and the control device 12, respectively.

[0063] An interface device 14 is provided on the chassis assembly 1. The interface device 14 includes a fluid interface, such as an air intake 141 (e.g., Figure 6 (as shown) and air outlet 142 (as shown) Figure 1 (As shown). A noise reduction device 11 is also installed on the chassis assembly 1, which includes a fan assembly 1112. The fan assembly 1112 is in fluid communication with both an air inlet 141 and an air outlet 142. Air and / or oxygen can enter the fan assembly 1112 through the air inlet 141 and be pressurized. The pressurized gas is then output through the air outlet 142 to a patient interface connected to the ventilation therapy equipment for the patient's breathing. The patient interface can be, for example, a breathing mask or nasal cannula. When the ventilation therapy equipment is in ventilator mode, it can be connected to a breathing mask; when it is in oxygen therapy mode, it can be connected to a nasal cannula.

[0064] like Figure 7 As shown, the interface device 14 may also include an electrical interface 144, such as a plug interface 1441; a USB interface 1442, etc.

[0065] Specifically, such as Figure 3 As shown, and please refer to Figure 8 and Figure 9 The chassis assembly 1 includes a support frame 110 and a first cover plate 120 and a second cover plate 130 respectively connected to the upper end of the support frame 110. Figure 9As shown, the support frame 110 is a frame structure with multiple functional compartments. Each functional compartment is separated from the others by partitions or baffles extending along the height of the support frame 110, thus forming relatively independent spaces. Therefore, each functional compartment, either individually or together with one of the first cover plate 120 and the second cover plate 130, defines a space for installing the aforementioned devices.

[0066] like Figure 4 As shown, and please refer to Figure 8 and Figure 9 A first functional compartment 111 is provided at the middle position of the support frame 110 (more specifically, near the rear side). The first functional compartment 111 and the first cover plate 120 together form a space for installing the noise reduction device 11, that is, the noise reduction device 11 is confined between the first functional compartment 111 and the first cover plate 120.

[0067] The noise reduction device 11 can be an existing noise reduction box structure, such as Figure 5 and Figure 6 As shown, the noise reduction device 11 is equipped with a fan assembly 1112. External air and oxygen can enter the fan assembly 1112 of the noise reduction device 11 for pressurization. The pressurized air or air-oxygen mixture can be output from the noise reduction device 11 and delivered to the patient for breathing.

[0068] like Figure 6 As shown, the fluid interface of the interface device 14 may include an air inlet 141 located on the rear side wall of the first functional compartment 111. The air inlet 141 includes an air intake 1411. One side of the air intake 1411 is connected to an air source, and the other side is connected to the air inlet of the noise reduction device 11 through an air bend 1413. That is, air can enter the noise reduction device 11 through the air intake 1411 and through the air bend 1413 and the air inlet of the noise reduction device 11.

[0069] like Figure 6 and Figure 7 As shown, a second functional compartment 112 is provided on the right side of the support frame 110. The second functional compartment 112 is used to install the oxygen control valve island 15. The oxygen control valve island 15 is connected to the oxygen inlet of the noise reduction device 11 through an oxygen bend 151. The oxygen control valve island 15 can control a certain number of valves and their signal processing processes, such as controlling the oxygen flow rate.

[0070] like Figure 7As shown, the air inlet 141 of the interface device 14 also includes a first oxygen inlet 1412 located on the rear wall of the second functional compartment 112. The two ends of the first oxygen inlet 1412 are connected to an oxygen generator (wall oxygen) and an oxygen control valve island 15, respectively. Therefore, the oxygen generator can input oxygen into the oxygen inlet of the noise reduction device 11 through the first oxygen inlet 1412, and the oxygen and air can be mixed in the noise reduction device 11. The oxygen control valve island 15 can control the flow rate of oxygen input into the oxygen inlet of the noise reduction device 11.

[0071] like Figure 7 As shown, the interface device 14 also includes a second oxygen inlet 147 located on the rear wall of the second functional compartment 112. One end of the second oxygen inlet 147 is connected to the oxygen control valve island 15, and the other end is connected to the oxygen cylinder. Therefore, in environments such as ambulances, oxygen can be supplied to the noise reduction device 11 by connecting the oxygen cylinder through the second oxygen inlet 147. The oxygen control valve island 15 can also control the flow rate of oxygen input to the oxygen inlet of the noise reduction device 11.

[0072] like Figure 3 As shown, the first cover plate 120 can cover the upper side of the first functional compartment 111 and the second functional compartment 112, and the second cover plate 130 can cover the upper side of the third functional compartment 113, thereby defining the corresponding functional compartments.

[0073] like Figure 7 As shown, and please refer to Figure 12 A third functional compartment 113 is provided on the left side of the support frame 110, and a second cover plate 130 is provided on the upper part of the third functional compartment 113. The third functional compartment 113 and the second cover plate 130 together define a space for placing the power supply module 17. Therefore, the electrical interface 144 of the interface device 14 may include a plug interface 1441, which can be connected to the power supply module 17 to enable power supply. Figure 7 As shown, the plug interface 1441 is connected to a plug.

[0074] The power supply module 17 can be connected to the fan assembly 1112 and the control device 12 in the noise reduction device 11 to provide them with power.

[0075] like Figure 12 As shown, a cooling fan 16 is also installed in the third functional compartment 113. Please refer to... Figure 7 The fluid interface of the interface device 14 may also include a cooling fan mounting interface 145 located on the rear side wall of the third functional compartment 113. The air outlet of the cooling fan 16 is installed in the cooling fan mounting interface 145. The cooling fan 16 can blow air to cool the power supply module 17 and other components on the chassis assembly 1.

[0076] like Figure 4 and Figure 5 As shown, a fourth functional compartment 114 is provided at the middle position (more specifically, near the front side) of the support frame 110. The battery device 13 includes a first capacitor 131, which is installed in the fourth functional compartment 114. It can provide emergency power in the event of a power failure. The first capacitor 131 is also connected to an alarm device to send an alarm signal to the alarm device in the event of a power failure.

[0077] like Figure 5 and Figure 10 As shown, a right side plate 117 is provided on the right side of the support frame 110, and the right side plate 117 and the support frame 110 together define the fourth functional compartment 114. A gas output pipe 1141 is provided in the space above the fourth functional compartment 114, and the gas output pipe 1141 is the main pipeline for supplying gas to the patient.

[0078] like Figure 10 As shown, the fluid interface of the interface device 14 includes an air outlet 142 and a proximal pressure interface 149 located on the right side plate 117. One end of the gas output pipeline 1141 is connected to the air outlet of the fan assembly 1112 in the noise reduction device 11, and the other end is connected to the air outlet 142, thereby outputting the pressurized gas in the fan assembly 1112. The gas pressurized by the fan assembly 1112 can be output through the air outlet and via the gas output pipeline 1141 to the air outlet 142, which is to the outside of the chassis assembly 1.

[0079] Furthermore, the gas output line 1141 serves as the main line, and branch lines can be formed on it by connecting hoses. For example, the gas output line 1141 is connected to the proximal pressure port 149 via a hose, and the proximal pressure port 149 is connected to the patient interface worn by the patient. Therefore, the gas pressure in the patient interface can be measured through the proximal pressure port 149.

[0080] like Figure 5 and Figure 13As shown, a flow sensor 1142 is installed on the gas output line 1141 to measure the gas flow rate in the gas output line 1141. A Y-shaped hose 1143 is also installed on the flow sensor 1142. One port of the Y-shaped hose 1143 is connected to the gas output line 1141 via a hose, and the other port is connected to the proximal pressure port 149. This means that a portion of the gas in the gas output line 1141 can enter the Y-shaped hose 1143 as purge gas. Since the proximal pressure port 149 is connected to the patient port, moisture carried by the patient's exhaled air may enter the proximal pressure port 149. Therefore, the Y-shaped hose 1143 can purge the proximal pressure port 149 to prevent moisture from affecting it. In addition, since the gas output line 1141 is the main line and the gas pressure in it is relatively high, in order to avoid the purge gas affecting the patient's use, an air resistance is provided in the interface where the Y-shaped hose 1143 connects to the gas output line 1141, thereby reducing the flow rate of the gas flowing from the gas output line 1141 to the Y-shaped hose 1143 so that it can be used as a purge gas.

[0081] like Figure 13 As shown, the gas output pipeline 1141 is also equipped with a mixed gas pressure sensor interface 1414, a proximal pressure branch interface 1415, and an oxygen concentration sensor interface 1416. The mixed gas pressure sensor interface 1414 is connected to a first pressure sensor 1144 located above the gas output pipeline 1141. The first pressure sensor 1144 can be a mixed gas pressure sensor used to measure the pressure of the mixed gas in the gas output pipeline 1141. The proximal pressure branch interface 1415 is connected to a second pressure sensor 1145 located above the gas output pipeline 1141 and to a third interface of the Y-shaped hose 1143. The second pressure sensor 1145 can be a proximal pressure sensor used to measure the proximal pressure.

[0082] Please continue reading Figure 13 The control device 12 also includes a third circuit board 124 located above the gas output pipeline 1141, which is connected to the first pressure sensor 1144, the second pressure sensor 1145 and the flow sensor 1142 to obtain pressure signals and flow signals.

[0083] Please continue reading Figure 13 An oxygen concentration sensor 1146 is also provided on the right side plate 117, which is connected to the oxygen concentration sensor interface 1416 on the gas output pipeline 1141 and is used to measure the oxygen concentration of the mixed gas in the gas output pipeline 1141.

[0084] In addition, the fluid interface of the interface device 14 also includes a mixed gas return interface 1417, which is disposed on the noise reduction device 11 and communicates with the air and oxygen mixing chamber in the noise reduction device 11. The mixed gas return interface 1417 is also connected to the oxygen concentration sensor 1146. Therefore, the mixed gas in the gas output pipeline 1141 enters the oxygen concentration sensor 1146 through the oxygen concentration sensor interface 1416 to measure the oxygen concentration. After being measured by the oxygen concentration sensor 1146, the gas can return to the air and oxygen mixing chamber in the noise reduction device 11 through the mixed gas return interface 1417, so that it can re-enter the fan assembly 1112 of the noise reduction device 11 for circulation.

[0085] like Figure 6 As shown, the support frame 110 also includes a fifth functional compartment 115, which is located between the third functional compartment 113 and the fourth functional compartment 114. The battery device 13 also includes a second capacitor 132, which is installed in the fifth functional compartment 115. It can provide emergency power in the event of a power outage. The second capacitor 132 is also connected to an alarm device to send an alarm signal to the alarm device in the event of a power outage.

[0086] The arrangement of the first capacitor 131 and the second capacitor 132 can be determined according to the space size of each functional compartment, such as... Figure 6 As shown, the first capacitor 131 is arranged horizontally, and the second capacitor 132 is arranged vertically.

[0087] like Figure 3 As shown, the control device 12 includes a circuit board above the noise reduction device 11, which is used to control and drive the fan. The circuit board includes a first circuit board 121 located on the first cover plate 120 and a second circuit board 122 located on the second cover plate 130, which can be connected to each other via an electrical connector 123. The first cover plate 120 and the second cover plate 130 can support the first circuit board 121 and the second circuit board 122 respectively, and can also isolate the first circuit board 121 and the second circuit board 122 from the functional compartments on the support frame 110 to ensure electrical safety.

[0088] like Figure 10 As shown, the interface device 14 also includes a blood oxygen interface 146 located on the rear side wall of the first cover plate 120, which can be connected to a blood oxygen finger clip attached to a patient's finger to measure the oxygen content in the blood. A power supply compartment is also provided at the bottom of the chassis assembly 1, in which a battery device 13 can be housed. The battery device 13 includes a battery cell 133 for powering the fan assembly 1112 and the control device 12, as well as a charging management circuit board.

[0089] Specifically, such as Figure 11As shown, a sixth functional compartment 116 is provided at the bottom of the support frame 110. The number of sixth functional compartments 116 can be one, two, or more. The sixth functional compartment 116 is used to house the battery unit 133. When the aforementioned plug interface 1441 cannot provide power, the battery unit 133 can supply power to the various components of the chassis assembly 1. The battery unit 133 can be, for example, one or more sets of dry cell batteries or rechargeable batteries.

[0090] The sixth functional compartment 116 can extend inward from the bottom surface of the support frame 110. After the battery unit 133 is installed, a cover can be installed on the sixth functional compartment 116 to enclose the battery unit 133 inside. The number, size, and shape of the partitions and baffles on the support frame 110 can be adjusted according to the components to be accommodated, and the layout of the components on the support frame 110 can also be adjusted according to the space available. For example, the power supply module 17 can be placed in the second functional compartment 112, and the oxygen control valve island 15 and other components can be placed in the third functional compartment 113.

[0091] The functional compartments on the support frame 110 not only provide installation space for components such as the noise reduction device 11, power supply module 17, and battery device 13, but also separate these components to facilitate their installation. The interface devices are correspondingly located on the side walls of the support frame 110 or the first cover plate 120, facilitating connection to other external components. Therefore, it can be seen that the support frame 110 of the chassis assembly 1 integrates the aforementioned functional components, thus possessing all the functions required for normal operation of the ventilation therapy equipment. Therefore, after the chassis assembly 1 is connected to the panel assembly 2, functional tests for the ventilation therapy equipment can be performed, including one or more of the following: pressure test, sealing test, flow test, and control test.

[0092] By integrating all the components necessary for the normal operation of the ventilation therapy device onto the chassis assembly 1, the chassis assembly 1 integrates all the functions required for the normal operation of the ventilation therapy device and the oxygen therapy unit. Therefore, when performing functional tests on the ventilation therapy device, it is not necessary to wait for all the components of the ventilation therapy device to be assembled into the housing 3 of the ventilation therapy device (e.g., ...). Figure 19 As shown, instead of testing the entire ventilation therapy equipment after assembly, functional tests are performed directly on the panel assembly 2. Only after passing these tests is the entire ventilation therapy equipment assembled. Therefore, on the one hand, since all components on the chassis assembly 1 are exposed, during testing, especially in case of abnormalities, there is no need to repeatedly disassemble and reassemble the ventilation therapy equipment's housing 3. Instead, any component can be retested at any time, thus improving efficiency. On the other hand, since there is no need for repeated disassembly and reassembly of the housing 3, the scrap rate of the housing 3 is also reduced.

[0093] Furthermore, when performing functional tests on chassis assembly 1, various parameters need to be input and the test results need to be visualized. Therefore, panel assembly 2 needs to be fixed on chassis assembly 1. Various parameters can be input and set through panel assembly 2, and the test process / results can be displayed on display screen 203.

[0094] like Figure 8 and Figure 9 As shown, a first connecting part is provided on the chassis assembly 1 (see...). Figure 8 and Figure 9 The panel assembly 2 has a second connecting part (see connection hole 101 in the middle). Figure 14 The hook 202 in the middle, the first connecting part and the second connecting part are connected by one or more of the following methods: plug connection, snap connection, sliding connection, magnetic connection or threaded connection.

[0095] The following explanation will be based on the example of the first connecting part and the second connecting part being connected by an insertion.

[0096] The first connecting part is located on the front side wall of chassis assembly 1. For example... Figure 9 As shown, and please refer to Figure 3 ,like Figure 14 As shown, the second connecting part is located on the back of the panel assembly 2. The second connecting part is along the height direction of the support frame 110 of the chassis assembly 1 (e.g., Figure 9 (Z-axis direction), length direction (e.g.) Figure 9 (in the X-axis direction) or the width direction (e.g.) Figure 9 (In the Y-axis direction) it is connected to the first connecting part.

[0097] The number of first connecting parts is at least two, and the at least two first connecting parts are spaced apart along the length direction of the chassis assembly 1. The number of second connecting parts is at least two, and they are arranged corresponding to the first connecting parts.

[0098] Specifically, the first connecting part includes either a connecting hole 101 or a connecting block, and the second connecting part includes either a connecting hole 101 or a connecting block, wherein the connecting hole and the connecting block are connected by mating.

[0099] In one implementation, such as Figure 9 As shown, and please refer to Figure 3 The support frame 110 of the chassis assembly 1 also includes a front sidewall 104 of the chassis. The front sidewall 104 of the chassis is located on the front side of the first functional compartment 111, the second functional compartment 112 and the third functional compartment 113. Its height may be lower than the partition or baffle that forms the first functional compartment 111, the second functional compartment 112 and the third functional compartment 113.

[0100] A mounting lug 102 protruding towards the panel assembly 2 is provided on the front sidewall 104 of the chassis, and a connecting hole 101 is provided on the mounting lug 102 and passes through the mounting lug 102. The mounting lug 102 can be a square structure, a columnar structure, a frustum-shaped structure, or other suitable structures. Correspondingly, the connecting hole 101 can be a slot or hole formed in the mounting lug 102.

[0101] like Figure 9 As shown, the lugs 102 protrude outward on the front sidewall 104 of the chassis. There can be multiple lugs 102, which are spaced apart along the length of the chassis assembly 1.

[0102] like Figure 14 and Figure 15 As shown, the panel assembly 2 includes a panel frame 201, and the connecting block includes a hook 202 that bends from the back of the panel frame 201 (i.e. the side opposite to the display screen 203) toward the bottom of the panel frame 201. The hook 202 can be inserted into the connecting hole 101 along the height direction of the chassis assembly 1 to connect with the connecting hole 101.

[0103] When connecting the panel assembly 2 to the chassis assembly 1, the panel frame 201 is moved from top to bottom along the height direction of the chassis assembly 1, so that the hook 202 is inserted into the corresponding connection hole 101, thereby fixing the panel assembly 2 to the chassis assembly 1. This connection method is convenient when connecting the panel assembly 2 to the chassis assembly 1 or removing the panel assembly 2 from the chassis assembly 1.

[0104] In another implementation, such as Figure 16 As shown, the chassis assembly 1 is the same as the aforementioned embodiment, except that in this embodiment, the front sidewall 104 of the chassis does not have a mounting lug 102, but the connecting hole 101 is directly provided on the front sidewall 104 of the chassis.

[0105] Understandably, in Figure 9 In the illustrated embodiment, a protruding lug 102 is provided on the front sidewall 104 of the chassis, and a connecting hole 101 can pass through the lug 102 in the same direction as the extending direction of the front sidewall 104 of the chassis. Figure 16In the illustrated embodiment, it is not necessary to provide an outwardly protruding lug 102 on the front sidewall 104 of the chassis. Instead, the connection hole 101 can be directly provided on the front sidewall 104 of the chassis. The connection hole 101 extends along a direction perpendicular to the extension of the front sidewall 104 of the chassis and penetrates through the front sidewall 104 of the chassis. Since there is a certain distance between the front sidewall 104 of the chassis and the inner bottom surface 103 of the support frame 110, that is, there is a certain distance between the connection hole 101 and the inner bottom surface 103 of the support frame 110, when the hook 202 is inserted into the connection hole 101, it can abut against the inner bottom surface of the support frame 110, thereby fixing the panel assembly 2 and the chassis assembly 1 together.

[0106] like Figure 14 and Figure 15 As shown, the panel assembly 2 includes a panel frame 201, and the connecting block includes a hook 202 that bends from the back of the panel frame 201 toward the bottom of the panel frame 201. The hook 202 can be inserted into the connecting hole 101 along the length and height directions of the chassis assembly 1 to connect with the connecting hole 101.

[0107] Since the connecting hole 101 is directly formed on the front side wall 104 of the chassis, when fixing the panel assembly 2 to the chassis assembly 1, first make the panel assembly 2 along the width direction of the chassis assembly 1 (e.g., Figure 16 Move the panel assembly 2 along the Y-axis direction, thereby inserting the hook 202 into the connecting hole 101, and then move the panel assembly 2 along the height direction of the chassis assembly 1 (e.g., along the Y-axis direction), so that the hook 202 extends into the connecting hole 101, and then move the panel assembly 2 along the height direction of the chassis assembly 1 (e.g., along the Y-axis direction). Figure 16 The panel assembly 2 moves along the Z-axis, causing the hook 202 to move downwards and abut against the inner bottom surface 103 of the support frame 110, thereby fixing the panel assembly 2 to the chassis assembly 1. This connection method is more conducive to the manufacturing of the support frame 110 and saves more materials.

[0108] Conversely, in another embodiment, the chassis assembly 1 is the same as in the aforementioned embodiment, except that in this embodiment, the connecting hole 101 is located on the inner bottom surface 103 and extends along the height direction of the chassis assembly 1. That is, in this embodiment, the connecting hole 101 can be directly provided on the inner bottom of the support frame 110. The panel assembly 2 includes a panel frame 201, and the connecting block includes a column extending from the back of the panel frame 201 toward the bottom end of the panel frame 201. The column can be inserted into the connecting hole 101 along the height direction of the chassis assembly 1 to connect with the connecting hole 101. This connection method is more conducive to the manufacture of the panel frame 201 and is more convenient when removing the panel assembly 2 from the chassis assembly 1.

[0109] Furthermore, the first connecting part and the second connecting part can also connect the chassis assembly 1 and the panel assembly 2 via a snap-fit ​​connection. For example, the first connecting part is a slot provided on the front side wall of the chassis assembly 1, and the second connecting part is a snap-fit ​​provided at the bottom end of the panel assembly 2. When connecting the panel assembly 2 to the chassis assembly 1, the panel assembly 2 is moved from top to bottom along the height direction of the chassis assembly 1, so that the snap-fit ​​is inserted into the slot; and when the snap-fit ​​contacts the slot, the snap-fit ​​deforms slightly to smoothly insert into the slot, thereby fixing the panel assembly 2 to the chassis assembly 1; when removing the panel assembly 2 from the chassis assembly 1, it can be pulled out of the slot by slightly deforming the snap-fit ​​again. In this embodiment, the connection between the panel assembly 2 and the chassis assembly 1 is more secure.

[0110] Furthermore, the first connecting part and the second connecting part can also be slidably connected to connect the chassis assembly 1 and the panel assembly 2. For example, the first connecting part is a sliding groove provided on two opposite side walls on the front side of the chassis assembly 1, and the second connecting part is a slider provided on both sides of the back of the panel assembly 2. When connecting the two, the slider can be inserted into the slot to fix the panel assembly 2 to the chassis assembly 1. When connecting the panel assembly 2 to the chassis assembly 1, the panel assembly 2 is moved from top to bottom along a direction with a certain angle to the height direction of the chassis assembly 1, so that the slider is inserted into the sliding groove; and as the panel assembly 2 and the chassis assembly 1 slide relative to each other, the slider moves from the top end of the sliding groove to the bottom end of the sliding groove, thereby fixing the panel assembly 2 to the chassis assembly 1; when removing the panel assembly 2 from the chassis assembly 1, it can be separated from the chassis assembly 1 by moving the panel assembly 2 in the opposite direction. In this embodiment, since the panel assembly 2 is tilted, meaning that the panel assembly 2 itself has a certain angle with the height direction of the chassis assembly 1, a groove with the same tilt angle as the panel assembly 2 is also provided on the chassis assembly 1. Therefore, when connecting the panel assembly 2 and the chassis assembly 1, the panel assembly 2 and the chassis assembly 1 can be quickly aligned. As long as the slider on the panel assembly 2 enters the groove on the chassis assembly 1, the groove will provide a certain support for the panel assembly 2, thus eliminating the need for the operator to continue supporting the panel assembly 2, and making installation easier.

[0111] like Figure 1 and Figure 2 As shown, the panel assembly 2 also includes a display screen 203 and a display cable (not shown) connected to the display screen 203. The display cable is electrically connected to the control device 12, wherein when the display screen is powered on, the chassis assembly 1 is able to perform functional tests for the ventilation therapy device, including one or more of pressure tests, sealing tests, oxygen concentration tests, flow tests, and control tests.

[0112] More specifically, the pressure test includes a mixed gas pressure sensor test performed at the mixed gas pressure sensor interface 1414, or a near-end pressure sensor test performed at the near-end pressure interface 149. The sealing test can be a sealing test performed at the outlet 142, or a gas passage leakage test, etc. The oxygen concentration test can be an oxygen concentration test performed at the oxygen concentration sensor interface 1416. The flow rate test can be a flow rate test performed at the outlet 142. The control test can be a fan control test performed on the fan assembly 1112 in the noise reduction device, etc.

[0113] When performing functional tests on chassis assembly 1, the panel assembly 2 is first fixed to chassis assembly 1, and the display cable is electrically connected to the control device 12 on chassis assembly 1, which in turn connects to the first circuit board 121 and the second circuit board 122. Therefore, by inputting / setting parameters on display screen 203, chassis assembly 1 can perform normal operation of the ventilation therapy equipment for various functional tests.

[0114] Secondly, if all tests are passed, the chassis assembly 1 and the panel assembly 2 can be placed together into the housing of the ventilation therapy equipment, thus completing the complete equipment and making it ready for shipment.

[0115] According to a second aspect of the present invention, the present invention provides a ventilation therapy device, which may be a ventilator or a high-flow humidified oxygen therapy device.

[0116] Specifically, such as Figures 17-20 As shown, the ventilation therapy device includes the chassis structure of the ventilation therapy device in the various embodiments described above, and also includes a housing 3 and a calibration connector 4 for accommodating the chassis structure. When the chassis assembly 1 performs functional tests on the ventilation therapy device, the chassis structure is located outside the housing 3. That is, when the chassis assembly 1 performs functional tests on the ventilation therapy device, the chassis structure is not assembled into the housing 3, but rather... Figure 1 The test is conducted in the indicated state. Therefore, during the test, all components on the chassis assembly 1 are exposed to the outside of the housing 3. If the test is abnormal, any component can be retested without repeatedly disassembling and reassembling the housing, thereby improving efficiency. On the other hand, since there is no need to repeatedly disassemble and reassemble the housing 3, the scrap rate of the housing 3 can also be reduced.

[0117] like Figure 19 As shown, the housing 3 has an internal space for accommodating the chassis assembly 1, which can be assembled into the housing 3 in various known ways.

[0118] like Figure 18As shown, a heat dissipation part 31 is also provided on the side of the housing 3. The heat dissipation part 31 corresponds to the third functional compartment 113 mentioned above. Since the power supply module 17 is installed in the third functional compartment 113, its power is relatively large and requires high heat dissipation. Therefore, the heat dissipation part 31 is provided at the corresponding position on the side of the housing 3 so as to dissipate it by air cooling.

[0119] In addition, a receiving portion 32 is provided at the rear of the housing 3 for accommodating the calibration connector 4. When in operation, the calibration connector 4 can perform various functional tests on the chassis assembly 1. For example, the calibration connector 4 can be connected to the air outlet 142 and the proximal pressure interface 149 to perform pressure tests, sealing tests, and flow tests. When not in operation, the calibration connector 4 can be stored in the receiving portion 32 to prevent loss.

[0120] like Figure 18 As shown, a shielding part 33 is also provided at the rear of the housing 3 at the position corresponding to the USB interface 1442 and the blood oxygen interface 146. It can be a silicone plug. When the USB interface 1442 and the blood oxygen interface 146 are not needed, the shielding part 33 can be used to block them to prevent foreign objects from entering the interface.

[0121] like Figure 19 As shown, the upper part of the housing 3 is also provided with a first handle groove 34. When the panel assembly 2 is fastened to the front side of the housing 3, the second handle groove 204 on the panel assembly 2 cooperates with the first handle groove 34 to form a handle groove structure that is easy to grip, making it easy to carry and transfer the ventilation therapy equipment.

[0122] like Figure 20 As shown, a suspension part 35 is also provided on the rear side of the housing 3. The suspension part 35 can be, for example, a hook. In emergency situations or when space is limited, the ventilation therapy device can be hung up and used through the suspension part 35, for example, by hanging it on an ambulance or on the railing of a hospital bed for easy access.

[0123] like Figure 20 As shown, a back plate 36 is also provided on the rear side of the housing 3, which can cover the receiving part 32 and the cooling fan mounting interface 145 and other interfaces to prevent foreign objects from entering the interfaces.

[0124] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
