[0002] Oxygen humidification bottle is a common device for humidifying oxygen. The device is generally installed between the medical oxygen supply system and the oxygen supply device. The oxygen delivered from the medical oxygen supply system first enters the neutral water in the humidification bottle from the air inlet pipe, and the neutral water humidifies the oxygen. The humidified oxygen is discharged and transported through the oxygen supply pipe and finally enters the oxygen supply device for the patient to inhale. The oxygen humidification bottle usually includes an outlet connector, and the oxygen supply pipe can be easily and quickly plugged into the outlet connector, thereby connecting the oxygen humidification bottle and the terminal oxygen supply device. However, in actual use, especially in the high-flow oxygen inhalation process, the oxygen supply pipe on the outlet connector may fall off due to the high oxygen inhalation pressure. The oxygen pipe falling off cannot be discovered in time, and even endangers the patient's life, thereby reducing the rescue survival rate. Therefore, a new type of oxygen supply device is urgently needed, which can remind medical staff in time when the oxygen pipe falls off, so as to reduce the occurrence of medical accidents.

[0028] The following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] This utility model is an oxygen delivery device with automatic alarm function. Figure 1-6 , including a nasal catheter 1, a humidification pool 2, an alarm device 3, a contact switch 4 and an elastic ejector 5. The humidification pool 2 is provided with a male plug connector 6, and the nasal catheter 1 is provided with a female plug connector 7 adapted to the male plug connector 6; the humidification pool 2 is provided with a slide groove 8, one end of the elastic ejector 5 is slidably set in the slide groove 8, and the other end extends out of the slide groove 8, the contact switch 4 is set in the slide groove 8, the control end of the contact switch 4 is set on the elastic ejector 5, and the contact switch 4 is electrically connected to the alarm device 9; during use, the nasal catheter 1 is detachably set through the female plug connector 7 On the male plug connector 6 on the humidification pool 2, the female plug connector 7 presses the elastic ejector pin 5, and the contact switch 4 is disconnected, so that a short circuit is formed between the contact switch 4 and the alarm device 9, and the alarm device 9 does not work; when the nasal catheter 1 falls off, the female plug connector 7 is separated from the male plug connector 6, and the contact switch 4 is closed. At this time, a closed circuit is formed between the contact switch 4 and the alarm device 9, and the alarm device 9 sounds an alarm, thereby promptly reminding medical staff to avoid failure to promptly discover that the nasal catheter 1 has fallen off, resulting in a life-threatening situation for the patient, thereby improving the rescue survival rate.

[0030] In this embodiment, the contact switch 4 includes a first electrode 10, a second electrode 11 and a conductor 12. The first electrode 10 and the second electrode 11 are both arranged on the side wall of the slide groove 8. The conductor 12 is arranged on the elastic ejector pin 5 and moves with the elastic ejector pin 5. The first electrode 10 and the second electrode 11 are respectively electrically connected to the alarm device 9. When the plug connector is separated from the male plug connector 6, the elastic ejector pin 5 drives the conductor 12 to move toward the first electrode 10 and the second electrode 11. When the two ends of the conductor 12 are respectively in contact with the first electrode 10 and the second electrode 11, the first electrode 10, the second electrode 11, the conductor 12 and the alarm device 9 form a closed circuit, thereby causing the alarm device 9 to sound an alarm, thereby promptly reminding medical staff to avoid failure to promptly discover that the nasal catheter 1 has fallen off, resulting in a life-threatening situation for the patient, thereby improving the rescue survival rate.

[0031] More preferably, the first electrode 10 and the second electrode 11 are conductive sheets, and the first electrode 10 and the second electrode 11 both extend toward the lower end of the slide slot 8, that is, the conductive member can contact the first electrode 10 and the second electrode 11 without making the elastic ejector pin 5 completely pop out of the slide slot 8. The lengths of the first electrode 10 and the second electrode 11 are set by the position of the conductive member when the female plug connector 7 is correctly plugged into the male plug connector 6 and the allowable plugging error of the female plug connector 7, and then the first electrode 10, the second electrode 11 and the alarm device 9 assist the medical staff to correctly place the nasal catheter 1 on the humidification tank 2. Secondly, when the female plug connector 7 tends to fall off, the first electrode 10 and the second electrode 11 extending toward the lower end of the slide slot 8 can remind the medical staff in advance.

[0032] In this embodiment, the elastic ejector 5 includes an ejector 13 and an elastic member 14. One end of the ejector 13 is slidably arranged in the slide groove 8, and the other end of the ejector 13 extends out of the slide groove 8. The elastic member 14 is arranged in the slide groove 8, and one end of the elastic member 14 abuts against the lower end of the slide groove 8, and the other end of the elastic member 14 abuts against the ejector 13. The conductor 12 is arranged on the ejector 13. When the nasal catheter 1 falls off, the elastic member 14 pushes the ejector 13 out of the slide groove 8.

[0033] In this embodiment, a limit block 15 is further provided at one end of the ejector pin 13 placed in the slide groove 8, and a limit groove matched with the limit block 15 is provided on the side wall of the slide groove 8. The limit block 15 is slidably arranged in the limit groove. The limit block 15 and the limit groove can not only prevent the ejector pin 13 from escaping from the slide groove 8, but also make the ejector pin 13 only perform telescopic movement in the slide groove 8, thereby ensuring that the conductive member can contact the first electrode 10 and the second electrode 11 at the same time.

[0034] In this embodiment, an air pressure sensor 16 is further included. The air pressure sensor 16 is arranged in the male plug connector 6. The air pressure sensor 16 is electrically connected to the alarm device 9. The air pressure sensor 16 can detect pressure changes in the male plug connector 6 or the nasal catheter 1. When the nasal catheter 1 is bent, the pressure in the male plug connector 6 or the nasal catheter 1 will change. Therefore, in the specific use process, the air pressure sensor 16 is used to detect whether the nasal catheter 1 is bent. When the nasal catheter 1 is bent, the air pressure sensor 16 controls the alarm device 9 to sound an alarm, reminding medical staff to adjust the nasal catheter 1 in time, thereby ensuring that oxygen can be provided to the patient normally.

[0035] Specifically, the air pressure sensor 16 is a piezoresistor, which is arranged at the air outlet of the male plug connector 6 in a ring-shaped structure, and detects the pressure change in the male plug connector 6 or the nasal catheter 1 through the piezoresistor.

[0036] The above disclosures are only several specific embodiments of the present invention, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
