[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a nasal oxygen tube loosening alarm mechanism and an oxygen supply auxiliary device. Background Art

[0002] Oxygen therapy is a commonly used treatment in clinical practice and an effective measure to treat hypoxemia and improve tissue hypoxia. Nasal oxygen cannula is the most commonly used oxygen inhalation device in clinical practice. At present, oxygen is mostly inhaled by aligning and inserting double nasal oxygen cannulas at the top of the bilateral nasal cavities. Patients who inhale oxygen in this way often experience tube detachment, resulting in failure to achieve the expected oxygen therapy effect. Nasal oxygen cannulas need to be frequently placed, which increases clinical nursing work and causes a certain amount of oxygen resource waste.

[0003] The current nasal oxygen cannula alarm device installs a temperature sensor on the nasal oxygen cannula. If the nasal oxygen cannula falls off, an alarm is sounded through the sensed temperature change. However, the temperature sensor is easily affected by changes in ambient temperature, and the patient's breathing state will also cause local temperature changes. Therefore, the reliability of this type of nasal oxygen cannula alarm device is difficult to guarantee. Utility Model Content

DETAILED DESCRIPTION

[0022] like Figure 1-4 As shown, the utility model provides a nasal oxygen tube loose alarm mechanism, comprising: an interface 11, an oxygen supply tube 12, a resistor 15, an alarm module 16 and a power supply 17. The interface 11 and the end of the oxygen supply tube 12 form a detachable joint, and a conductor 121 and a plurality of conductive protrusions 111 are arranged in the joint. The power supply 17, the alarm module 16 and the plurality of conductive protrusions 111 form a parallel circuit. When the interface 11 and the oxygen supply tube 12 are loose, the conductor 121 is out of contact with the plurality of conductive protrusions 111, so that the alarm module 16 is energized.

[0023] Compared with the prior art, the nasal oxygen tube loosening alarm mechanism provided by the utility model is connected to the oxygen supply tube 12 through the interface 11. The multiple conductive protrusions 111 are in contact with the conductor 121 to conduct electricity, short-circuiting the alarm module 16. The resistor 15 ensures that the entire circuit is normally energized. When the oxygen supply tube 12 is loose or falls out of the interface 11, the conductive protrusion 111 and the conductor 121 have poor contact or are separated, so that the alarm module 16 is in a powered state and an alarm is issued. The alarm is picked up by medical staff and can be dealt with in time. Since it is a contact alarm device, it is not easily affected by the ambient temperature and has higher reliability.

[0024] In one embodiment, the conductor 121 is disposed at the end of the oxygen supply tube 12, and a plurality of conductive protrusions 111 are disposed in the interface 11. Specifically, the conductor 121 is made of metal materials such as copper sheets, stainless steel sheets or aluminum sheets, and the shape of the outer contour is a curved surface structure, and is gap-matched with the inner wall of the interface 11. The conductive protrusion 111 is made of metal materials such as copper, iron or aluminum, and is in the shape of a thin rod, and is embedded in the interface 11. One end of the conductive protrusion 111 is connected to the power supply 17 and the alarm module 16 through a wire, and the other end is used to contact the conductor 121. In another embodiment, the conductor 121 is disposed in the interface 11, and a plurality of conductive protrusions 111 are disposed at the end of the oxygen supply tube 12.

[0025] In one embodiment, the conductor 121 is in the shape of a circular ring structure, and the conductive protrusion 111 is embedded in the interface 11, so that the conductor 121 can be sleeved on the end of the oxygen supply tube 12, and the connection structure is more reliable. In other embodiments, according to the shape of the inner wall of the interface 11, such as a polygon or an ellipse, the conductor 121 is in the shape of a polygonal column structure or an elliptical column structure.

[0026] Furthermore, the conductor 121 of the circular ring structure is nested at the end of the oxygen supply tube 12, and the side wall of the conductor 121 does not exceed the side wall of the oxygen supply tube 12, so that the oxygen supply tube 12 can be interference fit with the interface 11, thereby improving the firmness of the oxygen supply tube 12 and the interface 11.

[0027] In one embodiment, the interface 11 includes an externally threaded barrel, a limiting ring 124 and a nut 13 are provided at the end of the oxygen supply tube 12, the end of the oxygen supply tube 12 is inserted into the externally threaded barrel, and the inner end of the nut 13 cooperates with the externally threaded barrel to tighten the limiting ring 124.

[0028] Specifically, the limiting ring 124 is integrally formed with the oxygen supply tube 12, the interface 11 of the external threaded tube is communicated with and fixedly connected to the part worn by the patient, the oxygen supply tube 12 is inserted into the interface 11, so that the limiting ring 124 is close to or fits against the end of the interface 11, and one end of the nut 13 has a ring body extending inwardly thereof. During the process of screwing the nut 13 and the interface 11, the limiting ring 124 is gradually pressed against the interface 11, so that the connection between the oxygen supply tube 12 and the interface 11 is more reliable and not easy to fall off.

[0029] Furthermore, two interfaces 11 are arranged at intervals, and the oxygen supply tube 12 includes a main body 122 and two branch tube bodies 123. The two branch tube bodies 123 are respectively connected to the two interfaces 11 to form two joints, and the multiple conductive protrusions 111 in the two joints are connected in series. In this way, the two interfaces 11 correspond to the two nostrils of the patient, which improves the supply efficiency. In addition, the probability of the two branch tube bodies 123 falling off at the same time is smaller. If one branch tube body 123 falls off, the medical staff can be notified in time to handle it.

[0030] In this embodiment, the inner diameter of the branch tube body 123 is 1-5 mm, and the outer diameter is 2-8 mm.

[0031] In one embodiment, the two branch tubes 123 are perpendicular to the main tube 122. In this way, the main tube 122 does not need to be excessively bent to be connected to the feeding device, and it is not easy to cause the breathing mask to deviate. In other embodiments, the two branch tubes 123 and the main tube 122 can form a Y-shaped structure.

[0032] In this embodiment, the alarm module 16 is a warning light and / or a buzzer, and the warning light may be a light emitting diode.

[0033] In one embodiment, in order to realize remote alarm, the nasal oxygen tube loose alarm mechanism also includes an information transmission control module. The information transmission control module 14 is connected to the alarm module 16 in communication. The information transmission control module is an ESP32 single-chip microcomputer or an ESP8266 single-chip microcomputer, or the information transmission control module includes an STM32 single-chip microcomputer and a wireless transmission module, wherein the ESP32 single-chip microcomputer and the ESP8266 single-chip microcomputer have built-in control modules and wireless transmission modules. It should be noted that the information transmission module and control module of the nurse station can be components of the industrial computer, and the information transmission module of the nurse station can be integrated in the remote wireless control switch 18, such as Figure 4 As shown, the power source 17 , the resistor 15 and the alarm module 16 form a series circuit, and the plurality of conductive protrusions 111 in the connector are connected in parallel with the alarm module 16 .

[0034] It is connected to the oxygen supply tube 12 through the interface 11, and multiple conductive protrusions 111 are in contact with the conductor 121 to conduct electricity, short-circuiting the alarm module 16. The resistor 15 ensures that the entire circuit is powered on normally. When the oxygen supply tube 12 is loose or falls out of the interface 11, the conductive protrusions 111 and the conductor 121 are in poor contact or separated, so that the alarm module 16 is in a powered-on state. The information transmission control module 14 receives the signal of the current change, processes the information, and sends a command to the remote wireless control switch 18 of the nurse station. The alarm module 16 of the nurse station is powered on and an alarm is sounded, which is received by medical staff. Each alarm module 16 of the nurse station has a corresponding room number and can be processed in time. Since it is a contact alarm device, it is not easily affected by the ambient temperature and has higher reliability.

[0035] like Figure 5 As shown, the utility model provides an oxygen supply auxiliary device, including a breathing mask 21 connected with a nasal oxygen tube loosening alarm mechanism. The use of the oxygen supply auxiliary device can provide patients with safer and more reliable oxygen therapy.

[0036] In one embodiment, the information transmission control module 14, resistor 15, alarm module 16 and power supply 17 in the ward are installed on the inner side or outer side of the breathing mask 21 and sealed by a plastic shell or a plastic film. The power supply 17 is a lithium battery or a button battery. Of course, the power supply 17 can also be an external power supply. A switch can also be set on the breathing mask 21 and connected to the circuit.
