[0038] Embodiment 1

[0039] Please refer to Figure 1-2 , specifically, in the embodiment of the breathing circuit detachment alarm device 1, the breathing circuit detachment alarm device 1 provided in this application is connected to the breathing circuit to monitor whether the breathing circuit has detached. The breathing circuit detachment alarm device 1 specifically includes: a first universal interface 11, a second universal interface 12, and a slow-release structure 13. The slow-release structure 13 is connected between the first universal interface 11 and the second universal interface 12.

The hard outer shell 131 and the microporous slow-release membrane 132 enclose a containing space. The volatile aromatic substance is evenly attached to the solid matrix 133. The solid matrix 133 is located in the containing space. The microporous slow-release membrane 132 surrounds to form a hollow columnar structure. The columnar structure is respectively connected to the first universal interface 11 and the second universal interface 12 to form a ventilation channel 15 of the breathing circuit. The first universal interface 11 and the second universal interface 12 are fixedly connected to the hard outer shell 131. Among them, the volatile aromatic substance is harmless to the human body.

[0040] Specifically, an embodiment of the present invention provides a breathing circuit detachment alarm device 1, which is connected to a breathing circuit for monitoring whether the breathing circuit has detached. The breathing circuit detachment alarm device 1 specifically includes: a first universal interface 11, a second universal interface 12, and a slow-release structure 13. The slow-release structure 13 is connected between the first universal interface 11 and the second universal interface 12. The slow-release structure 13 includes a rigid outer shell 131, a microporous slow-release membrane 132, a volatile aromatic substance, and a solid matrix 133 for adsorbing the volatile aromatic substance. The rigid outer shell 131 and the microporous slow-release membrane 132 enclose a containing space. The volatile aromatic substance is uniformly attached to the solid matrix 133. The solid matrix 133 is located in the containing space. The microporous slow-release membrane 132 surrounds to form a hollow columnar structure. The columnar structure is respectively connected to the first universal interface 11 and the second universal interface 12 to form a ventilation channel 15 of the breathing circuit. The first universal interface 11 and the second universal interface 12 are fixedly connected to the rigid outer shell 131. Among them, the volatile aromatic substance is harmless to the human body. In the embodiment of the present application, by uniformly adsorbing a safe volatile aromatic substance on the solid matrix 133, the volatile aromatic substance can be evenly distributed and slowly released in the solid matrix 133 to extend the volatilization time of the volatile aromatic substance. At the same time, by fixing the solid matrix 133 adsorbed with the volatile aromatic substance in the containing space formed by the enclosure of the rigid outer shell 131 and the microporous slow-release membrane 132, the volatile aromatic substance can be slowly and stably released into the breathing circuit through the microporous slow-release membrane 132. When the breathing circuit detaches, the volatile aromatic substance will quickly diffuse into the air, and medical staff can smell an obvious aromatic smell, so that medical staff can be reminded in time of the detachment of the breathing circuit by means of smell perception, improving the safety of patients.

[0041] In a possible implementation manner, the microporous slow-release membrane 132 is a microporous aluminum membrane, and gaseous molecules volatilized from the volatile aromatic substance can stably pass through the microporous aluminum membrane and enter the breathing circuit. The gaseous molecules volatilized from the volatile aromatic substance are safe and harmless to the human body, and even substances beneficial to the human body can be selected as the volatile aromatic substance.

[0042] In a possible implementation manner, the volatile aromatic substance can also be citral, and the solid matrix 133 is selected as a gel matrix that can adsorb citral to achieve the stable release of citral through the gel matrix.

[0043] In yet another possible implementation manner, the volatile aromatic substance can be a fragrant natural plant essential oil extracted from lemon peel or osmanthus, and the solid matrix 133 can be a natural polymer that adsorbs the natural plant essential oil. The natural polymer can be agar or gelatin to achieve the stable release of the natural plant essential oil through the natural polymer.

[0044] In a possible implementation, the first universal interface 11 is detachably connected to the endotracheal tube 4 of the breathing circuit, and the second universal interface 12 is detachably connected to the tube at the ventilator 2 end of the breathing circuit.

[0045] Among them, the first universal interface 11 is adapted to the endotracheal tube 4 of the breathing circuit so that the first universal interface 11 can be detachably connected to the end of the endotracheal tube 4, and the second universal interface 12 is adapted to the corrugated tube 3 led out from the ventilator 2 end of the breathing circuit so that the second universal interface 12 can be detachably connected to the end of the corrugated tube 3.

[0046] In a possible implementation, the rigid outer shell 131, the first channel interface, and the second channel interface are all made of medical plastic, which is convenient and hygienic to use and avoids the risk of cross-infection.

[0047] In a possible implementation, the breathing circuit detachment alarm device 1 further includes: a monitoring and alarm component 14. The monitoring and alarm component 14 is fixedly arranged on the rigid outer shell 131. The monitoring and alarm component 14 includes a monitoring end, a comparison end, and an alarm end. The monitoring end is exposed to the air to monitor the actual concentration of volatile aromatic substances in the air. The comparison end is used to compare the actual concentration with a preset concentration. When the actual concentration is greater than the preset concentration, the alarm end is triggered to send out an alarm.

[0048] Specifically, the monitoring and alarm component 14 can be arranged on the rigid outer shell 131 by an embedding method, so that when medical staff fail to detect the smell emitted in the air in time, the detection and alarm component can be used to monitor whether the breathing circuit has fallen off, which is more accurate than manual perception.

[0049] In addition, this application is a disposable consumable and can be used to monitor whether the breathing circuit leaks or falls off during the operation.

The corrugated tube 3 is led out from the air outlet of the ventilator 2, and the breathing circuit detachment alarm device 1 is connected between the corrugated tube 3 and the endotracheal tube 4 to form a ventilation channel 15 between the corrugated tube 3 and the endotracheal tube 4.

[0052] Specifically, the specific structure of the breathing circuit disconnection alarm device 1 in this embodiment has been described in detail in the first embodiment, and will not be elaborated here. By connecting the breathing circuit disconnection alarm device 1 between the ventilator 2 and the endotracheal tube 4, the monitoring of the breathing circuit can be realized. When the breathing circuit leaks or disconnects, the breathing circuit disconnection alarm device 1 will release an odor, which can be perceived by medical staff and identified by the monitoring alarm component 14, thereby reminding the medical staff that the breathing circuit has leaked or disconnected.
