[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0056] As shown in Figures 1 to 5B , embodiments of the present invention provide a ventilation device 100, which may be, but is not limited to, a ventilator. The ventilation device 100 includes a housing 10, an air circuit assembly 20, and a pressure monitoring assembly 30. The housing 10 has an inner cavity 11, and the outer side of the housing 10 is recessed inward to form a receiving cavity 12. The air circuit assembly 20 includes an oxygen control assembly 24 and an output interface 22. The oxygen control assembly 24 is used to connect to an oxygen supply device, and the output interface 22 is used to connect to an inspiratory branch and deliver a mixture of oxygen and air to the patient through the inspiratory branch. The pressure monitoring component 30 is arranged in the inner cavity 11. The pressure monitoring component 30 is at least used to communicate with the gas circuit component 20 to monitor the relevant parameters of the input and / or output gas of the gas circuit component (20). It should be noted that the pressure monitoring component 30 is connected to the gas circuit component 20. The pressure monitoring component 30 can be directly connected to the gas circuit component 20 for communication, or the pressure monitoring component 30 can be indirectly connected to the gas circuit component 20 but the two are connected. For example, the pressure monitoring component 30 is connected to the inhalation branch, and the gas circuit component 20 is also connected to the inhalation branch. The pressure monitoring component 30 and the gas circuit component 20 are connected through the inhalation branch. The receiving cavity 12 is used to detachably receive at least one portable medical device 200. The portable medical device 200 includes an interface side 201. The interface side 201 of the portable medical device 200 is provided with a cable interface 202. When the portable medical device 200 is received in the receiving cavity 12, the output interface 22 and the cable interface 202 are located on different sides of the housing 10. It should be noted that the output interface 22 and the cable interface 202 are located on different sides of the housing 10, including the output interface 22 and the cable interface 202 being located on opposite sides of the housing 10, and also including the output interface 22 and the cable interface 202 being located on adjacent sides of the housing 10. The portable medical device 200 can be, but is not limited to, a monitoring device.

[0057] The ventilation device main unit 100 proposed in the embodiment of the present invention, first, by providing a receiving cavity 12 on the outer side of the housing 10, the user can install the portable medical device 200 in the receiving cavity 12 according to actual use needs, thereby expanding the function of the ventilation device and broadening the scope of use. In some emergency situations, it can reduce the trouble of wiring and instrument transportation. Secondly, by providing a detachable receiving cavity 12 for the portable medical device 200, when the user does not need to use the extended functions of the portable medical device 200, the portable medical device 200 can be removed and the ventilation device main unit 100 can be used only as a ventilation device, thereby improving the flexibility of use and reducing the overall weight of the ventilation device main unit 100. In addition, when the portable medical device 200 is accommodated in the receiving cavity 12, the cable interface 202 of the portable medical device 200 and the output interface 22 of the gas circuit assembly 20 are located on different sides of the housing 10. This separates the connecting pipelines of the gas circuit assembly 20 and the connecting cables of the portable medical device 200, avoids the confusion of pipeline connections, and facilitates the use of the ventilation device main unit 100.

[0058] As shown in Figures 2 and 3, by way of example, the housing 10 includes a front panel A1, a back panel A2, a top panel A3, a bottom panel A4, a left side panel A5, and a right side panel A6. The front panel A1 is disposed opposite the back panel A2, the top panel A3 is disposed opposite the bottom panel A4, and the left side panel A5 is disposed opposite the right side panel A6. One of the cable interface 202 and the output interface 22 is located on the left side panel A5 of the housing 10, and the other of the cable interface 202 and the output interface 22 is located on the right side panel A6 of the housing 10. Of course, one of the cable interface 202 and the output interface 22 may also be located on the back panel A2 of the housing 10, and the other of the cable interface 202 and the output interface 22 may be located on the front panel A1 of the housing 10. The specific arrangement may be determined based on actual design requirements.

[0059] It should be noted that the panel A1, back panel A2, top panel A3, bottom panel A4, left panel A5 and right panel A6 are for the ventilation equipment host 100 in normal use. Panel A1 is the panel facing the operator, usually the side with operation keys and / or display screen.

[0060] It should also be noted that the output interface 22 and the cable interface 202 are not limited to being located on two opposite sides of the shell 10. The output interface 22 and the cable interface 202 can also be located on any adjacent sides of the panel A1, back panel A2, top panel A3, left panel A5 and right panel A6. As long as the output interface 22 and the cable interface 202 are located on different sides of the shell 10, the connecting pipelines of the air circuit assembly 20 and the connecting cables of the portable medical device 200 can be distinguished to avoid messy pipeline connections.

[0061] In one embodiment, the cable interface 202 is located on the side of the left side panel A5, and the output interface 22 is located on the right side panel A6.

[0062] In one embodiment, the gas circuit assembly 20 includes a gas output assembly 23 , which is used to receive a gas formed by mixing oxygen and air. The gas output assembly 23 includes the output interface 22 .

[0063] As shown in FIG3 , in one embodiment, the ventilation device main unit 100 further includes a pressure sampling interface 40, which connects the pressure monitoring assembly 30 and the inspiratory branch. The pressure sampling interface 40 and the output interface 22 are located on the same side of the housing 10. In this embodiment, the connecting pipeline of the pressure sampling interface 40 and the connecting pipeline of the air circuit assembly 20 are located on the same side of the housing 10, separate from the connecting cables of the portable medical device 200, which can avoid cluttered pipeline connections and facilitate the use of the ventilation device main unit 100.

[0064] It should be noted that the pressure sampling interface 40 is not limited to the above-described embodiment. For example, in another embodiment, the ventilation device main unit 10 further includes an exhalation valve 50, which is mounted on the housing 10 and is used to receive gas exhaled by the patient. The pressure sampling interface 40 is disposed inside the housing 10 and connects the pressure monitoring assembly 30 and the exhalation valve 50. The pressure monitoring assembly 30 is used to monitor relevant parameters of the gas at the exhalation valve 50.

[0065] As shown in FIG3 , in one embodiment, the ventilation device main unit 100 further includes an exhalation valve 50, which includes an inlet port 51 and an outlet port 52. The inlet port 51 is used to connect to the exhalation branch and receive the patient's exhaled gas through the exhalation branch. The inlet port 51 and the outlet port 22 are located on the same side of the housing 10. In this embodiment, the connecting pipeline of the inlet port 51 of the exhalation valve 50 and the connecting pipeline of the air circuit assembly 20 are located on the same side of the housing 10, separate from the connecting cables of the portable medical device 200, which can avoid cluttered pipeline connections and facilitate the use of the ventilation device main unit 100.

[0066] In one embodiment, the air outlet port 51 is partially located on the back panel A2 of the housing, and the air outlet port 52 is partially located on the right side panel A6 of the housing. In this embodiment, when the air outlet port 51 is partially blocked by a wall, other medical equipment, or a quilt, for example, when the air outlet port 51 is located on the back panel A2, the air outlet port 52 on the right side panel A6 can still be ventilated, thereby preventing the patient from being unable to exhale.

[0067] As shown in Figures 4, 5A, and 5B, in one embodiment, the ventilation device main unit 100 further includes a turbine mechanism 110, and the gas output assembly 23 has an input interface 21 and an output interface 22. An oxygen control assembly 24 is connected to the turbine mechanism 110 and is used to connect to an oxygen supply device to direct oxygen supplied by the oxygen supply device into the turbine mechanism 110. The input interface 21 is connected to the turbine mechanism 110, and the gas output by the turbine mechanism 110 enters the gas output assembly 23 through the input interface 21.

[0068] It should be noted that the oxygen control component 24 is connected to the gas output component 23, and the connection can be achieved by directly connecting the oxygen control component 24 to the gas output component 23, or by indirectly connecting the oxygen control component 24 to the gas output component 23. For example, in some embodiments, the ventilation device host 100 further includes a turbine mechanism 110, and the oxygen control component 24 and the gas output component 23 are both connected to the turbine mechanism 110, and the oxygen control component 24 and the gas output component 23 are connected through the turbine mechanism 110.

[0069] In one embodiment, the oxygen control assembly 24 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.

[0070] In one embodiment, the gas output assembly 23 includes a release valve and a second flow sensor, wherein when the pressure of the output gas is greater than a preset value, the release valve opens to release part of the gas to balance the pressure, and the second flow sensor is used to monitor the flow of the output gas.

[0071] As shown in FIG2 , in one embodiment, the ventilation device main unit 100 further includes an oxygen interface 60, which is connected to the oxygen control assembly 24 via a pipeline. The oxygen interface 60 is used to connect to an oxygen supply device to deliver oxygen supplied by the oxygen supply device to the oxygen control assembly 24. The oxygen interface 60 and the cable interface 202 are located on the same side of the housing 10. In this embodiment, by providing the oxygen interface 60 and the oxygen control assembly 24 separately, the oxygen interface 60 and the oxygen control assembly 24 can be flexibly arranged, effectively utilizing the internal space of the housing 10, and achieving miniaturization of the ventilation device main unit 100.

[0072] In one embodiment, the receiving chamber 12 has a cavity opening, the oxygen interface 60 and the cavity opening are located on the same side of the shell 110, and the receiving chamber 12 is close to the bottom plate A4 and the back plate A2.

[0073] As shown in Figures 2 and 3, in one embodiment, the shell 10 includes a first side panel, a second side panel and a third side panel, which are on different surfaces and are connected to each other, wherein the accommodating cavity 12 is formed by an inward depression of one of the first side panel, the second side panel and the third side panel.

[0074] Taking the example of the first side panel being the left side panel A5, the second side panel being the back panel A2, and the third side panel being the top panel A3, the receiving cavity 12 can be formed by the left side panel A5 being recessed inward, or the back panel A2 being recessed inward, or the top panel A3 being recessed inward. Of course, this is merely an example. Depending on actual use needs, the receiving cavity 12 can be formed by any one of the front panel A1, back panel A2, top panel A3, left side panel A5, and right side panel A6 being recessed inward, and the specific design can be determined based on actual design needs.

[0075] In one embodiment, the receiving cavity 12 is formed by two of the first side panel, the second side panel, and the third side panel being recessed inward. Taking the first side panel being the left side panel A5, the second side panel being the back panel A2, and the third side panel being the top panel A3 as an example, as shown in FIG6 , the receiving cavity 12 can be formed by the left side panel A5 and the top panel A3 being recessed inward, or by the left side panel A5 and the top panel A3 being recessed inward, or by the back panel A2 and the top panel A3 being recessed inward. Of course, this is just an exemplary explanation. According to actual use needs, the receiving cavity 12 can be formed by any two adjacent ones of the panel A1, the back panel A2, the top panel A3, the left side panel A5, and the right side panel A6 being recessed inward. The specific form can be determined according to actual design needs.

[0076] In one embodiment, the receiving cavity 12 is formed by the inward depression of three of the first side panel, the second side panel, and the third side panel. Taking the first side panel being the left side panel A5, the second side panel being the back panel A2, and the third side panel being the top panel A3 as an example, as shown in FIG7 , the receiving cavity 12 is formed by the inward depression of the left side panel A5, the back panel A2, and the top panel A3. Of course, this is just an exemplary description. According to actual use needs, the receiving cavity 12 can be formed by any three adjacent inward depressions of the panel A1, the back panel A2, the top panel A3, the left side panel A5, and the right side panel A6. The specific design can be determined according to actual design needs.

[0077] As shown in Figures 8 and 9, in one embodiment, the ventilation device main unit 100 further includes a first retaining structure 70, which is connected to the housing 10. The first retaining structure 70 is configured to cooperate with the portable medical device 200 to securely accommodate the portable medical device 200 within the accommodating cavity 12. In this embodiment, the cooperation between the first retaining structure 70 and the portable medical device 200 prevents the portable medical device 200 from falling out of the accommodating cavity 12 during transportation of the ventilation device main unit 100.

[0078] In one embodiment, the first limiting structure 70 includes a limiting member 71 that is movably connected to the housing 10 and has an open position and a closed position. When the limiting member 71 is moved to the open position, the portable medical device 200 can be freely removed from the receiving cavity 12. When the limiting member 71 is moved to the closed position, the limiting member 71 abuts the portable medical device 200 to prevent the portable medical device 200 from being removed from the receiving cavity 12.

[0079] As shown in FIG9 , in one embodiment, a stopper 71 is disposed at the edge of the receiving cavity 12 and is rotatably connected to the housing 10. When the stopper 71 is rotated to the open position, the stopper 71 is located outside the contour of the receiving cavity 12. When the stopper 71 is rotated to the closed position, the stopper 71 is partially located within the contour of the receiving cavity 12, thereby restricting the portable medical device 200 from being removed from the receiving cavity 12. In this embodiment, when the portable medical device 200 needs to be loaded into the receiving cavity 12, the stopper 71 is first rotated to the open position. At this time, the stopper 71 does not block the receiving cavity 12, and the portable medical device 200 can be freely loaded into or removed from the receiving cavity 12. After the portable medical device 200 is loaded into the receiving cavity 12, the stopper 71 is rotated to the closed position. At this time, the stopper 71 blocks the portable medical device 200, preventing the portable medical device 200 from falling out of the receiving cavity 12. When the portable medical device 200 needs to be removed from the receiving cavity 12 , the limiting member 71 is first rotated to the open position, and then the portable medical device is taken out of the receiving cavity 12 .

[0080] It should be noted that the limiting member 71 is not limited to being rotatably connected to the housing 10. For example, in another embodiment, as shown in FIG10 , the inner side wall of the receiving chamber 12 is provided with a slide groove, and the outer side surface of the housing 10 is provided with an operating port 13 connected to the slide groove. The first limiting structure 70 includes a limiting member 71 and a first elastic member 72. The limiting member 71 includes a limiting portion 711 and an operating portion 712 connected to the limiting portion 711. The limiting portion 711 is slidably disposed in the slide groove, and the operating portion 712 is disposed in the operating port 13. By toggling the operating portion 712, the limiting portion 711 can be driven to move to an open position. In the open position, the limiting portion 711 is located in the slide groove. The first elastic member 72 is disposed in the slide groove and abuts the limiting portion 711. The first elastic member 72 is used to provide a driving force to drive the limiting portion 711 to a closed position. In the closed position, the limiting portion 711 partially extends into the receiving chamber 12 to prevent the portable medical device 200 from being removed from the receiving chamber 12. In this embodiment, when the portable medical device 200 needs to be loaded into the receiving cavity 12, the operating portion 712 is first pushed to move the limiting member 71 to the open position. At this time, the limiting member 711 does not block the receiving cavity 12, and the portable medical device 200 can be freely loaded into or removed from the receiving cavity 12. After the portable medical device 200 is loaded into the receiving cavity 12, the operating portion 712 is released. The limiting member 71 now extends into the receiving cavity 12 under the elastic force of the first elastic member 72. At this time, the limiting member 711 blocks the portable medical device 200, preventing the portable medical device 200 from falling out of the receiving cavity 12. When the portable medical device 200 needs to be removed from the receiving cavity 12, the operating portion 712 is first pushed to move the limiting member 71 to the open position, and then the portable medical device can be removed from the receiving cavity 12.

[0081] It should be noted that the first limiting structure 70 is not limited to the above configuration. For example, in another embodiment, as shown in Figures 11 to 15, the housing 10 includes a top, a bottom, and side portions surrounding the top and bottom. The receiving cavity 12 is formed by the side portions being recessed into the interior of the housing 10. The receiving cavity 12 includes a bottom wall 121 and a first side wall 122 adjacent to the bottom wall 121, with the bottom wall 121 facing the cavity opening of the receiving cavity 12. Preferably, the first side wall 122 is the side wall that supports the bottom of the portable medical device 200, and the portable medical device 200 rests on the first side wall 122 under the action of gravity. The first limiting structure 70 includes a protrusion 73 and a lifting assembly 74. The protrusion 73 protrudes from the first side wall 122 and is configured to engage with a second limiting structure 203 provided on the portable medical device 200 to prevent the portable medical device 200 from being removed from the receiving cavity 12. The lifting assembly 74 is used to lift the portable medical device 200 when subjected to an external force, so that the second limiting structure 203 of the portable medical device 200 is disengaged from the protrusion 73. In this embodiment, when the portable medical device 200 needs to be installed, the portable medical device 200 only needs to be pushed into the receiving cavity 12 until the protrusion 73 engages with the second limiting structure 203. At this time, under the restriction of the protrusion 73, the portable medical device 200 will not fall out of the receiving cavity 12. When the portable medical device 200 needs to be removed from the receiving cavity 12, the operator operates the lifting assembly 74 to lift the portable medical device 200 so that the second limiting structure 203 of the portable medical device 200 is disengaged from the protrusion 73. The limiting effect of the protrusion 73 is lost, and the portable medical device 200 can be directly removed from the receiving cavity 12.

[0082] In one embodiment, the first limiting structure 70 further includes a housing 75 having a protrusion 73. The lifting assembly 74 includes a lifting member 741 and a pushing member 742. The lifting member 741 is slidably connected to the housing 75 along a first direction X and is used to lift the portable medical device 200 along the first direction X. The pushing member 742 is slidably connected to the housing 75 along a second direction Y and is used to drive the lifting member 741 upward to lift the portable medical device 200. The second direction Y is set at an angle to the first direction X. When the portable medical device 200 needs to be removed from the receiving cavity 12, the operator manually pushes the pushing member 742 along the second direction Y. The pushing member 742 drives the lifting member 741 to lift the portable medical device 200, thereby separating the portable medical device 200 from the protrusion 73.

[0083] In one embodiment, the lifting assembly 74 further includes a first return member, which is disposed on the housing 75 and is used to provide a driving force to drive the lifting member 741 downward. In this embodiment, when the operator removes the external force applied to the pushing member 742, the lifting member 741 descends under the action of the first return member, facilitating the subsequent engagement of the portable medical device 200 with the protrusion 73 when it is subsequently reinstalled into the receiving cavity 12. The first return member can be, but is not limited to, a spring.

[0084] It should be noted that, in another embodiment, the lifting assembly 74 may not be provided with the first restoring member. When the portable medical device 200 is loaded into the receiving cavity 12 , the portable medical device 200 may also drive the lifting member 741 to descend by relying on its gravity.

[0085] In one embodiment, the lifting assembly 74 further includes a second return member, which is disposed on the housing 75 and is used to provide a driving force to reset the pusher 742. In this embodiment, when the operator removes the external force applied to the pusher 742, the pusher 742 is moved to its initial position under the action of the second return member, making it easier for the operator to subsequently push the pusher 742 to lift the lifting member 741. The second return member can be, but is not limited to, a spring.

[0086] It should be noted that, in another embodiment, the lifting assembly 74 may not be provided with a second reset member. In this embodiment, the lifting member 741 is provided with a first inclined surface 7411, and the pushing member 742 is provided with a second inclined surface 7421. When the lifting member 741 descends, the lifting member 741 can push the pushing member 742 to reset through the cooperation of the first inclined surface 7411 and the second inclined surface 7421.

[0087] As shown in FIG14 , in one embodiment, the first limiting structure 70 further includes a pushing mechanism 76 , which is disposed on the bottom wall 121 and is configured to provide a driving force to push the portable medical device 200 out of the receiving cavity 12 . It should be noted that, in this embodiment, the pushing mechanism 76 only pushes out a portion of the portable medical device 200 from the receiving cavity 12 , making it easier for the operator to grasp the pushed-out portion of the portable medical device 200 to remove the entire portable medical device 200 . Of course, in other embodiments, the pushing mechanism 76 may also push the entire portable medical device 200 out of the receiving cavity 12 , and the specific method may be determined based on actual design requirements.

[0088] In one embodiment, the bottom wall 121 has a hole 1211, and the ejection mechanism 76 includes an ejection member 761 and a second elastic member 762. The ejection member 761 is disposed in the hole 1211 and can partially extend along the hole 1211. The second elastic member 762 is disposed in the inner cavity 11 and abuts the ejection member 761. The second elastic member 762 is used to provide a driving force for the ejection member 761 to extend from the hole 1211. The second elastic member 762 can be, but is not limited to, a spring. During the process of being loaded into the receiving cavity 12, the portable medical device 200 abuts the ejection member 761 and gradually compresses the second elastic member 762. When the portable medical device 200 is lifted by the lifting member 741 and disengaged from the protrusion, the compressed second elastic member 762 pushes the portable medical device 200 out through the elastic force. In this embodiment, the ejection mechanism 76 has a simple structure, which is conducive to simplifying the mechanism, reducing the complexity of the mechanism, and improving the reliability of the mechanism.

[0089] It should be noted that the ejection mechanism 76 is not limited to the aforementioned ejection member 761 in conjunction with the second elastic member 762. For example, in other embodiments, the ejection mechanism 76 may include a motor, a transmission mechanism, and an ejection member 761. The ejection member 761 is connected to the motor via the transmission mechanism. When the motor is running, the transmission mechanism drives the ejection member 761 to eject the portable medical device 200 from the receiving chamber 12. The transmission mechanism may be, but is not limited to, a crank-connecting rod mechanism, a rack and pinion pair, or a cam transmission mechanism. In other embodiments, the ejection mechanism 76 may also employ a pneumatic cylinder push rod, an electric push rod, an electromagnet mechanism, or the like.

[0090] It should be noted that the first limiting structure 70 is not limited to the above configuration. For example, in another embodiment, as shown in Figures 15 to 18, the receiving cavity 12 includes a bottom wall 121 and a first side wall 122 and a second side wall 123 disposed on opposite sides of the bottom wall 121. The bottom wall 121 is opposite the cavity opening of the receiving cavity 12. The first limiting structure 70 includes a blocking portion 77 disposed on the first side wall 122. The second limiting structure 203 includes a spring 2031 and an abutting portion 2032. The spring 2031 includes a first end and a second end opposite the first end. The first end of the spring 2031 is connected to the portable medical device 200, and the abutting portion 2032 is connected to the spring 2031. When the portable medical device 200 is inserted into the receiving cavity 12, the abutting portion 2032 abuts against the blocking portion 77 to prevent the portable medical device 200 from being removed. The abutting portion 2032 can be disengaged from the blocking portion 77 by pressing the spring 2031.

[0091] Optionally, the blocking portion 77 is a groove provided on the first side wall 122, and the abutting portion 2032 is embedded in the groove. Of course, the blocking portion 77 is not limited to being a groove, and can also be a protrusion, and the abutting portion 2032 abuts against the protrusion.

[0092] As shown in Figures 15 and 17, in one embodiment, the first side wall 122 is provided with a first latch position S1 at the edge of the receiving cavity 12. In one embodiment, the second end of the elastic piece 2031 is exposed at the first latch position S1. The first latch position S1 can be formed by the first side wall 122 extending outwardly at an angle at the cavity opening of the receiving cavity 12. In this embodiment, the provision of the first latch position S1 facilitates the operator's disassembly and assembly of the portable medical device 200.

[0093] As shown in Figures 15 and 17, in one embodiment, the second side wall 123 is provided with a second hand position S2 at the edge of the receiving cavity 12. Similarly, by providing the second hand position S2, the cooperation between the second hand position S2 and the first hand position S1 facilitates the operator to disassemble and assemble the portable medical device 200. Specifically, when the portable medical device 200 needs to be removed from the receiving cavity 12, the operator inserts the thumb into the second hand position S2 and inserts the index finger and the middle finger into the second hand position S2. This is only an example and is not a specific limitation. The finger inserted into the first hand position S1 can be at least one of the four fingers other than the thumb. After the index finger and the middle finger are inserted into the second hand position S2, the index finger and the middle finger press the second end of the spring piece 2031 until the abutting portion 2032 is disengaged from the blocking portion 77. Then, the thumb, index finger, and middle finger apply force to pull the portable medical device 200 out of the receiving cavity 12.

[0094] As shown in Figures 15 and 16, in one embodiment, the receiving chamber 12 includes a bottom wall 121, which is opposite to the opening of the receiving chamber 12. The bottom wall 121 is provided with a first interface component 1212. The first interface component 1212 is used to electrically connect to the second interface component 204 provided on the portable medical device 200. In this embodiment, the portable medical device 200 can be powered by a battery provided within the ventilation device main unit 100 and / or communicate with a control component provided within the ventilation device main unit 100 through the cooperation between the first interface component 1212 and the second interface component 204.

[0095] As shown in Figures 15 and 16, in one embodiment, the housing 10 includes a top, a bottom, and side portions surrounding the top and bottom. A receiving cavity 12 is formed by the side portions being recessed into the interior of the housing 10. The receiving cavity 12 includes a bottom wall 121 and side walls surrounding the bottom wall 121, with the bottom wall 121 opposing the opening of the receiving cavity 12. The side walls are provided with a first guide structure 101 extending in the direction of insertion of the portable medical device 200. The first guide structure 101 is configured to cooperate with a second guide structure 102 provided on the portable medical device 200 to guide the portable medical device 200 when inserted into the receiving cavity 12. In this embodiment, the first guide structure 101 and the second guide structure 102 guide the portable medical device 200 so that the portable medical device 200 can be installed in the correct position. Furthermore, the cooperation between the first guide structure 101 and the second guide structure 102 can also prevent the portable medical device 200 from shaking in a direction perpendicular to the insertion direction.

[0096] Optionally, the first guide structure 101 is a protrusion 73 and the second guide structure 102 is a groove. It should be noted that the positions of the protrusion 73 and the groove can be reversed, that is, the first guide structure 101 is a groove and the second guide structure 102 is a protrusion 73.

[0097] As shown in FIG19 , in one embodiment, the ventilation device main unit 100 further includes a handle 80 connected to the housing 10 and provided with a prompt structure. In this embodiment, the prompt structure facilitates user identification of the handle 80 and / or the ventilation device main unit 100.

[0098] In one embodiment, the prompt structure includes a light source that emits light to provide a prompt to the user. Of course, the prompt structure is not limited to the above configuration. In other embodiments, the prompt structure includes a silk-screen ink layer with reflective powder added, which provides a prompt to the user by reflecting light. In other embodiments, the prompt structure includes a reflective strip with a reflective structure, which provides a prompt to the user by reflecting light.

[0099] In one embodiment, the ventilation device main unit 100 includes a front side having an operation panel, the handle 80 includes a front side facing the front side of the ventilation device main unit 100, and the prompt structure is provided on the front side of the handle 80. Of course, the prompt structure is not limited to being provided on the front side of the handle 80, and can also be provided on other sides of the handle 80, depending on actual design requirements.

[0100] As shown in FIG19 , in one embodiment, the handle 80 includes a crossbar 81, a first connecting rod 82, and a second connecting rod 83. The crossbar 81 is located at the top of the housing 10 and extends in the left-right direction of the housing 10. The prompt structure is provided on the crossbar 81. The crossbar 81 includes a first end and a second end. The first connecting rod 82 connects the first end of the crossbar 81 to the housing 10, and the second connecting rod 83 connects the second end of the crossbar 81 to the housing 10. The crossbar 81, the first connecting rod 82, and the second connecting rod 83 form a U-shaped structure.

[0101] As shown in Figures 19 and 20, in one embodiment, the ventilation device main unit 100 further includes a protective member 90, which is connected to the housing 10. The protective member 90 is configured to protrude from the surface of the housing 10 to a greater height than the portable medical device 200 protrudes from the surface of the housing 10. In this embodiment, when the ventilation device main unit 100 is impacted or accidentally dropped during transportation, the protective member 90 is impacted first, thereby protecting the portable medical device 200 from damage caused by the impact. The protective member 90 is made of an elastic material. Alternatively, the protective member 90 can be made of, but is not limited to, a silicone material.

[0102] In one embodiment, the housing 10 includes a front side, a rear side, a left side, and a right side. The left side includes a first top edge L1, a first bottom edge L2, and a first side edge L3 near the front. The right side includes a second top edge L4, a second bottom edge L5, and a second side edge L6 near the front. The rear side includes a third bottom edge L7. The protective member 90 is elongated and extends sequentially along the first top edge L1, the first side edge L3, the first bottom edge L2, the third bottom edge L7, the second bottom edge L5, the second side edge L6, and the second top edge L4.

[0103] As shown in Figures 21 and 22, in one embodiment, the ventilation device main unit 100 further includes a turbine mechanism 110. The turbine mechanism 110 is disposed within the inner cavity 11 and communicates with the air circuit assembly 20. The turbine mechanism 110 and the receiving cavity 12 are arranged side by side vertically in the height direction of the ventilation device main unit 100, and the air circuit assembly 20 is arranged diagonally to the receiving cavity 12 (i.e., the air circuit assembly 20 and the exhalation valve 50 are arranged side by side vertically). In this embodiment, the turbine mechanism 110 and the air circuit assembly 20 are rationally arranged, effectively and rationally utilizing the internal space of the housing 10, thereby reducing the size of the ventilation device main unit 100 and meeting the requirements of miniaturization.

[0104] It should be noted that it is not limited to the turbine mechanism 110 and the receiving chamber 12 being arranged side by side in the height direction of the ventilation device main unit 100, and the pressure monitoring component 30 and the receiving chamber 12 being arranged side by side in the width direction of the ventilation device main unit 100. As long as one of the turbine mechanism 110, the air path component 20 and the pressure monitoring component 30 is arranged side by side with the receiving chamber 12 in the height direction of the ventilation device main unit 100, the other of the turbine mechanism 110, the air path component 20 and the pressure monitoring component 30 is arranged side by side with the receiving chamber 12 in the width direction of the ventilation device main unit 100, and the remaining one of the turbine mechanism 110, the air path component 20 and the pressure monitoring component 30 is arranged diagonally with the receiving chamber 12, as long as the size of the ventilation device main unit 100 can be reduced so that the ventilation device main unit 100 meets the miniaturization requirements, it will be sufficient.

[0105] In one embodiment, the ventilation device main unit 100 includes an upper region G1 and a lower region G2. The upper region G1 includes a first region G11 and a second region G12 parallel to the first region G11. The lower region G2 includes a third region G21 and a fourth region G22 parallel to the third region G21. The first region G11 and the third region G21 are parallel in the height direction of the ventilation device main unit 100, and the second region G12 and the fourth region G22 are parallel in the height direction of the ventilation device main unit 100. The ventilation device main unit 100 also includes an exhalation valve 50. The housing 10 is recessed inward to form an assembly cavity. The exhalation valve 50 is removably mounted in the assembly cavity. The turbine mechanism 110 is located in the first region G11, the air circuit assembly 20 is located in the second region G12, the receiving cavity 12 is located in the third region G21, and the assembly cavity is located in the fourth region G22.

[0106] In one embodiment, the oxygen control assembly 24 is connected to the turbine mechanism 110. The oxygen control assembly 24 inputs oxygen into the turbine mechanism 110, mixes with the gas inside the turbine mechanism 110, and then enters the gas output assembly 23. It should be noted that in another embodiment, the ventilation device main unit 100 does not have a turbine mechanism 110, and the oxygen control assembly 24 is connected to the gas output assembly 23. The oxygen control assembly 24 inputs oxygen into the gas output assembly 23.

[0107] In one embodiment, the ventilation device main unit 100 further includes a first control panel H1 and a second control panel H2 located within the housing 10. The first control panel H1 is located between the storage chamber and the panel A1 of the housing 10, and the second control panel H2 is located below the gas output assembly 23. The first control panel H1 is used for, but not limited to, controlling the portable medical device 200. The second control panel H2 is used for, but not limited to, controlling the turbine mechanism 110.

[0108] As shown in Figure 23, in one embodiment, the ventilation device host 100 also includes a support plate P and a battery assembly K. The support plate P is horizontally arranged inside the shell 10. Above the support plate P are the upper area G1 and the lower area G2 mentioned above. Below the support plate P forms a bottom area G3, and the battery assembly K is accommodated in the bottom area G3. The battery assembly K is used to supply the power required for the operation of the ventilation device host 100.

[0109] In this embodiment, the support plate P is provided to separate the battery assembly K from the aforementioned gas circuit assembly 20, pressure monitoring assembly 30, and turbine mechanism 110. This facilitates protection between the two components, reduces mutual interference between them, and improves safety. Secondly, by designating the bottom area G3 to accommodate the battery assembly K, the center of gravity of the ventilation device mainframe 100 is lowered when the battery assembly K is accommodated in the bottom area G3, allowing the ventilation device mainframe 100 to be stably placed on a supporting surface.

[0110] In one embodiment, the bottom region G3 and the battery assembly K are both flat, with the battery assembly K laid flat on the bottom region G3. This embodiment helps lower the center of gravity of the ventilation device main unit 100, making it more stable and reducing the height of the entire ventilation device main unit 100, thereby achieving miniaturization requirements.

[0111] In one embodiment, the battery assembly K includes a battery protective cover K1 and a battery K2. The battery K2 protective cover K1 is connected to the housing, and the battery K2 is accommodated in the battery K2 protective cover K1. Optionally, the battery K2 protective cover K1 has a hollow structure K11 for heat dissipation.

[0112] As shown in FIG24 , in one embodiment, an air inlet 120 is provided on the back of the ventilation device main unit 100. The air inlet 120 is connected to the turbine mechanism 110, and air enters the turbine mechanism 110 through the air inlet 120. It should be noted that the air inlet 120 is not limited to being located on the back of the ventilation device main unit 100 and can be located according to the actual location of the gas inlet of the turbine mechanism 110. For example, in another embodiment, the gas inlet of the turbine mechanism 110 is located on the left side of the ventilation device main unit 100. Accordingly, the air inlet 120 can be located on the left side panel A5 of the ventilation device main unit 100.

[0113] As shown in Figure 24, in one embodiment, the ventilation device host 100 also includes a filter component 130. A filter component accommodating cavity 140 is provided on the back of the ventilation device host 100. The cavity opening of the filter component accommodating cavity 140 is the air inlet 120. The filter component 130 can be removably accommodated in the filter component accommodating cavity 140.

[0114] As shown in FIG24 , in one embodiment, the ventilation device main unit 100 further includes a protrusion 150, which is protruding from the back of the housing 10. In this embodiment, when the ventilation device main unit 100 is placed with its back against a wall or other medical equipment, the protrusion 150 can separate the back panel A2 of the ventilation device main unit 100 from the wall or other medical equipment, preventing the air inlet 120 from being blocked by the wall or other medical equipment, thereby ensuring smooth air intake for the turbine mechanism 110.

[0115] As shown in Figures 24 and 25 , in one embodiment, the housing 10 includes a left side, a right side, and a back side. The housing 10 is provided with an air inlet 14 and an air outlet 15. The air inlet 14 is located on the left side of the housing 10, and the air outlet 15 is located on the back side of the housing 10. The ventilation device main unit 100 also includes a gas drive assembly 160. The gas drive assembly 160 is disposed in the inner cavity 11 and is used to drive gas from the air inlet 14 into the inner cavity 11 and then out of the air outlet 15.

[0116] In one embodiment, the air inlet 14 is located at the first handle position S1.

[0117] In one embodiment, the gas driving assembly 160 includes a first fan 1601 and a second fan 1602 . The first fan 1601 is disposed on the back plate A2 of the housing 10 , and the second fan 1602 is disposed at the air outlet 15 .

[0118] In one embodiment, the housing 10 includes a backplate A2 and a panel A1 opposite the backplate A2. The backplate A2, turbine mechanism 110, gas circuit assembly 20, and pressure monitoring assembly 30 of the housing 10 form a first airflow channel. The panel A1, turbine mechanism 110, gas circuit assembly 20, and pressure monitoring assembly 30 of the housing 10 form a second airflow channel. That is, after the gas enters the interior of the housing 10 from the air inlet 14, it flows in two paths. One of the airflow paths enters the gap between the backplate A2 and the turbine mechanism 110 under the obstruction and guidance of the turbine mechanism 110, then flows through the gas circuit assembly 20 and the pressure monitoring assembly 30 in sequence before being discharged from the air outlet 15. The other airflow path enters the gap between the panel A1 and the turbine mechanism 110 under the obstruction and guidance of the turbine mechanism 110, then flows through the gas circuit assembly 20 and the pressure monitoring assembly 30 in sequence before being discharged from the air outlet 15. In this embodiment, after the air enters the interior of the housing 10 from the air inlet 14 , it can fully carry away the heat inside the housing 10 , thereby achieving a better heat dissipation effect.

[0119] In one embodiment, the ventilation device host 100 further includes at least one portable medical device 200, which is removably received in the receiving cavity 12. The portable medical device 200 may be, for example, a monitoring device without a display screen and with a power supply, a monitoring device without a display screen and a power supply, or a transport monitoring device with a display screen and a power supply.

[0120] As shown in FIG2 , in one embodiment, the ventilation device host 100 further includes a display screen 103 , which is mounted on the panel A1 . The display screen 103 is at least used to display the respiratory waveform and monitoring parameters.

[0121] As shown in Figures 1 to 26, an embodiment of the present invention further provides a ventilation device host. The proposed ventilation device host 100 includes a housing 10, a display screen 103, an air circuit assembly 20, and a pressure monitoring assembly 30. The housing 10 has an inner cavity 11, and the outer side of the housing 10 is recessed inward to form a receiving cavity 12. The display screen 103 is mounted on the housing 10. The air circuit assembly 20 includes an oxygen control assembly 24 and an output interface 22. The oxygen control assembly 24 is used to connect to an oxygen supply device, and the output interface 22 is used to connect to an inspiratory branch and deliver gas to the patient through the inspiratory branch. The pressure monitoring assembly 30 is disposed in the inner cavity 11. The pressure monitoring assembly 30 is at least used to communicate with the air circuit assembly 20 to monitor parameters related to the input and / or output gas of the air circuit assembly 20. Among them, the accommodating cavity 12 is used to detachably accommodate at least one portable medical device 200, and the portable medical device 200 includes an interface side 201, and the interface side 201 of the portable medical device 200 is provided with a cable interface 202. Among them, when the portable medical device 200 is accommodated in the accommodating cavity 12, the output interface 22 and the cable interface 202 are located on two adjacent sides of the shell 10, and the output interface 22 is located on the side of the shell 10 where the display screen 103 is provided (as shown in Figure 26).

[0122] The ventilation device main unit 100 proposed in this embodiment, first, by providing a receiving chamber 12 on the outer side of the housing 10, the user can install the portable medical device 200 in the receiving chamber 12 according to actual use needs, thereby expanding the function of the ventilation device and broadening its scope of use. In some emergency situations, it can reduce the trouble of wiring and instrument transportation. Secondly, by providing a removable receiving chamber 12 for the portable medical device 200, when the user does not need to use the extended functions of the portable medical device 200, the portable medical device 200 can be removed and the ventilation device main unit 100 can be used only as a ventilation device, thereby improving the flexibility of use and reducing the overall weight of the ventilation device main unit 100. In addition, when the portable medical device 200 is accommodated in the receiving chamber 12, the output interface 22 and the cable interface 202 are located on adjacent sides of the housing 10, and the output interface 22 is located on the side of the output interface 22 where the display screen 103 is provided. This separates the connecting pipes of the gas circuit assembly 20 and the connecting cables of the portable medical device 200, avoids the confusion of pipe connections, and facilitates the use of the ventilation device main unit 100.

[0123] In one embodiment, the gas circuit assembly 20 includes a gas output assembly 23 , which is used to receive a gas formed by a mixture of oxygen and air. The gas output assembly 23 includes the output interface 22 .

[0124] In one embodiment, the ventilation device host 100 further includes an exhalation valve 50, which includes an air inlet interface 51, and the air inlet interface 51 is used to connect the exhalation branch, wherein the air inlet interface 51 and the output interface 22 are located on the same side of the housing 10. In this embodiment, the output interface 22 and the air inlet interface 51 are provided on the same side panel, which is convenient for the operator to plug in the inhalation branch and the respiratory branch. In one embodiment, the operator can fix the plug-in end of the inhalation branch and the plug-in end of the exhalation branch together, and set them to be consistent with the spacing between the output interface 22 and the air inlet interface 51. In this way, the operator can plug the inhalation branch and the exhalation branch into place with the output interface 22 and the air inlet interface 51 at one time, thereby improving operational efficiency.

[0125] The structures, connection relationships and beneficial effects of other components of the ventilation device host 100 proposed in this embodiment can refer to the above embodiments and will not be described in detail here.

[0126] As shown in Figures 1 to 26, an embodiment of the present invention further provides a ventilation device host 100. The proposed ventilation device host 100 includes a housing 10, an air circuit assembly 20, and a pressure monitoring assembly 30. The housing 10 has an inner cavity 11. The outer side of the housing 10 is recessed inward to form a receiving cavity 12. The air circuit assembly 20 is disposed in the inner cavity 11. The air circuit assembly 20 includes an oxygen control assembly 24 and a gas output assembly 23. The oxygen control assembly 24 is used to connect to an oxygen supply device. The gas output assembly 23 is used to receive a gas formed by a mixture of oxygen and air. The gas output assembly 23 includes an output interface 22. The output interface 22 is used to connect to an inspiratory branch and deliver gas to a patient through the inspiratory branch. The pressure monitoring assembly 30 is disposed in the inner cavity 11. The pressure monitoring assembly 30 is at least used to communicate with the air circuit assembly 20 to monitor parameters related to the input and / or output gas of the air circuit assembly 20. The receiving cavity 12 is used to detachably receive at least one portable medical device 200 and includes an opening for inserting the portable medical device 200. The output interface 22 and at least a portion of the opening are located on different sides of the housing 10. For example, the output interface 22 is located on the right side panel of the housing 10, and at least a portion of the opening is located on the left side panel, back panel, or top panel of the housing 10.
