[0046] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0047] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0049] In the description of this embodiment, the terms "upper", "lower", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0050] like Figure 1-Figure 3As shown, this embodiment provides a non-invasive ventilator pipeline for preventing pressure sores and condensation water reflux, including a first connecting pipe 1, a three-way joint 2, a condensation water collection tank 3, a water level alarm 4, a second connecting pipe 5, a nasal catheter 6, a foam dressing 8 and a snap 7. The first end of the first connecting pipe 1 is used to connect the non-invasive ventilator. The three-way joint 2 is provided with a first connecting end 21, a second connecting end 22 and a third connecting end 23, and the first connecting end 21 is connected to the second end of the first connecting pipe 1. The top of the condensation water collection tank 3 is detachably connected to the second connecting end 22, and a one-way valve is provided in the second connecting end 22. The water level alarm 4 is provided on the condensation water collection tank 3, and when the water level in the condensation water collection tank 3 is higher than the preset water level, the water level alarm 4 alarms. The first end of the second connecting pipe 5 is connected to the third connecting end 23. One end of the nasal catheter 6 is connected to the second end of the second connecting pipe 5, and the patient breathes oxygen through the nasal catheter 6. One side of the foam dressing 8 is used to stick to the patient's cheek. The snap button 7 is disposed on the other side of the foam dressing 8 and is used to connect the nasal catheter 6 and the foam dressing 8 .

[0051] In the present embodiment, a non-invasive ventilator circuit for preventing pressure sores and condensation water backflow is provided. The condensation water in the first connecting tube 1 and the second connecting tube 5 is collected by providing a condensation water collection tank 3. A water level alarm 4 is provided on the condensation water collection tank 3. When the water level in the condensation water collection tank 3 is higher than the preset water level, the water level alarm 4 alarms to promptly remind the nursing staff that the water level in the condensation water collection tank 3 is too high, so that the nursing staff does not need to pay attention to the condensation water level in real time. A one-way valve is provided in the second connecting end 22 of the three-way joint 2, so that the condensation water entering the three-way joint 2 from the first connecting end 21 and the third connecting end 23 can enter the condensation water collection tank 3 while preventing the condensation water collection tank 3 from backflowing into the three-way joint 2, thereby preventing the condensation water in the condensation water collection tank 3 from backflowing into the second connecting tube 5 when the condensation water collection tank 3 is tilted. In addition, by providing a foam dressing 8 to support the nasal catheter 6, the pressure of the nasal catheter 6 on the patient's cheek is dispersed, so as to prevent the nasal catheter 6 from exerting excessive local pressure on the patient's cheek and causing pressure sores.

[0052] Further, such as Figure 3 As shown, the first connection end 21 and the second connection end 22 are arranged opposite to each other, and the third connection end 23 is arranged in the middle of the three-way joint 2, so that the condensed water in the first connecting pipe 1 and the second connecting pipe 5 can enter the condensed water collection tank 3 through the third connection end 23.

[0053] Furthermore, if Figure 1As shown, both the first connecting pipe 1 and the second connecting pipe 5 are bellows. Since the bellows have the property of being straightened, when it is necessary to clean the condensed water in the first connecting pipe 1 and the second connecting pipe 5, the first connecting pipe 1 and the second connecting pipe 5 can be straightened to facilitate the condensed water in the first connecting pipe 1 and the second connecting pipe 5 to flow into the condensed water collection tank 3, so that as little condensed water as possible is retained in the first connecting pipe 1 and the second connecting pipe 5.

[0054] Furthermore, if Figure 2 As shown, the water level alarm 4 includes a water level sensor 41 and a buzzer 42. The water level sensor 41 is arranged in the condensed water collection tank 3. The buzzer 42 is arranged outside the condensed water collection tank 3 and is electrically connected to the water level sensor 41. The cooperation of the water level sensor 41 and the buzzer 42 to realize the monitoring and alarm of the water level belongs to the prior art, and the further structure and principle are not repeated here.

[0055] Alternatively, if Figure 2 As shown, a fixed gripping clip 32 is provided at the top of the condensate collection tank 3, and the fixed gripping clip 32 is used to fix the condensate collection tank 3. When a non-invasive ventilator pipeline for preventing pressure sores and condensate reflux is used, the condensate collection tank 3 is fixed to the head of the bed by the fixed gripping clip 32, so that the position of the condensate collection tank 3 and the first connecting pipe 1 is stable and will not move with the movement of the patient. It can be understood by those skilled in the art that the fixed gripping clip 32 is also a clip fixed to the condensate collection tank 3, and the condensate collection tank 3 is fixed by clamping the fixed gripping clip 32 on the head of the bed.

[0056] Optionally, the one-way valve is a duckbill valve. The duckbill valve has the characteristics of a one-way valve, and at the same time, the duckbill valve is a normally closed valve, that is, when the condensate collection tank 3 is removed to process the condensate, the outside air will not enter the three-way connector 2 through the second connecting end 22, thereby avoiding contamination of the oxygen breathed by the patient.

[0057] Optionally, the second connecting end 22 of the three-way joint 2 is provided with an external thread, and the mouth of the condensate collection tank 3 is provided with an internal thread, and the condensate collection tank 3 is threadedly connected to the second connecting end 22 of the three-way joint 2 to facilitate disassembly of the condensate collection tank 3.

[0058] Alternatively, if Figure 1 As shown, the second connecting pipe 5 is coated with a heat insulation layer 9. By coating the second connecting pipe 5 with the heat insulation layer 9, the generation of condensed water in the second connecting pipe 5 is reduced. It can be understood by those skilled in the art that, since the second connecting pipe 5 is a corrugated pipe, the length of the heat insulation layer 9 is longer than the length of the second connecting pipe 5 under normal conditions to ensure that the second connecting pipe 5 can be stretched normally.

[0059] Further, the heat insulating layer 9 is a tubular plastic film, and the heat insulating layer 9 is sealed and connected to the second connecting pipe 5. The second connecting pipe 5 is insulated by the air between the tubular plastic film and the second connecting pipe 5 and the tubular plastic film.

[0060] Alternatively, if Figure 1 and Figure 4 As shown, two nasal tubes 61 are provided on the nasal catheter 6, and the nasal tubes 61 are used to be inserted into the patient's nostrils. An air source interface 62 is provided on one side of the nasal catheter 6, and the air source interface 62 is used to connect to the second connecting tube 5. Extension pieces 63 are provided on both sides of the nasal catheter 6, and the extension pieces 63 are used to be fixed to the patient's cheeks.

[0061] Furthermore, if Figure 1 and Figure 4 As shown, by providing a foam dressing 8 to support the nasal catheter 6, the pressure of the extension piece 63 of the nasal catheter 6 on the patient's cheek is dispersed, so as to prevent the nasal catheter 6 from exerting excessive local pressure on the patient's cheek and causing pressure sores. Specifically, the snaps 7 and the extension pieces 63 are provided one by one, and the extension pieces 63 on both sides of the nasal catheter 6 are fixed to the foam dressing 8 by the snaps 7. The foam dressing 8 is an existing product in the medical field.

[0062] Furthermore, if Figure 1 and Figure 4 As shown, the snap button 7 includes a fixing portion 71 and a buckling portion 72. The fixing portion 71 is bonded and fixed to one side of the foam dressing 8. One end of the buckling portion 72 is rotatably connected to the fixing portion 71, and the other end can be buckled with the fixing portion 71. A receiving groove is provided between the buckling portion 72 and the fixing portion 71. The receiving groove is used to accommodate the extension piece 63 of the nasal catheter 6. The extension pieces 63 on both sides of the nasal catheter 6 are respectively extended into the receiving grooves of the two snap buttons 7. The extension piece 63 is fixed by the buckling between the buckling portion 72 and the fixing portion 71. By arranging the foam dressing 8 between the extension piece 63 of the nasal catheter 6 and the patient's cheek, the local pressure of the extension piece 63 on the patient's cheek is reduced. When the buckling portion 72 needs to be removed from the patient's face, it is only necessary to press the buckling portion 72 to release the buckling between the buckling portion 72 and the fixing portion 71, and the extension piece 63 can be taken out from the receiving groove. The further specific structures of the fixing portion 71 and the buckling portion 72 of the snap button 7 are common knowledge in the art and will not be described in detail here.

[0063] Furthermore, if Figure 1 and Figure 4As shown, the foam dressing 8 includes a first adhesive portion 81 and a second adhesive portion 82, which are respectively used to be attached to the two sides of the patient's cheeks. A snap button 7 is bonded and fixed to each of the first adhesive portion 81 and the second adhesive portion 82. The extension plate 63 on one side of the nasal catheter 6 is fixed to the first adhesive portion 81 by the snap button 7 on the first adhesive portion 81, and the extension plate 63 on the other side is fixed to the second adhesive portion 82 by the snap button 7 on the second adhesive portion 82. In this embodiment, as shown in FIG. Figure 1 and Figure 4 As shown, the edges of the first adhesive portion 81 and the second adhesive portion 82 are both arc-shaped. The first adhesive portion 81 and the second adhesive portion 82 with arc-shaped edges are less likely to curl during use, and can effectively extend the adhesion time of the first adhesive portion 81 and the second adhesive portion 82 to the patient's cheek, thereby extending the use time of the foam dressing 8.

[0064] Furthermore, if Figure 1 and Figure 4 As shown, the foam dressing 8 also includes a connecting portion 83, and the first adhesive portion 81 and the second adhesive portion 82 are connected by the connecting portion 83. The connecting portion 83 can be adhered between the patient's nose and mouth (that is, the position of the patient's upper lip) to support the middle part of the nasal catheter 6 and prevent the middle part of the nasal catheter 6 from exerting excessive local pressure on the patient's upper lip.

[0065] In this embodiment, if Figure 1 and Figure 4 As shown, the upper edge and the lower edge of the connecting portion 83 are also arc-shaped, so that the connecting portion 83 is not easy to curl during the use of the foam dressing 8, thereby extending the use time of the foam dressing 8.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
