The following describes in detail the anti-pulling alarm device of the embodiment of the present invention with reference to the accompanying drawings.

Referring to FIG. 1 to FIG. 4 , the anti-tube removal alarm device provided according to the embodiment of the present invention includes a sensing device 10 and a prompting device 20 .

Specifically, the sensing device 10 is adapted to be fixed on the dressing 30 at the intubation site on the human body, so as to detect whether there is a limb approaching. The prompting device 20 is connected with the sensing device 10 in wireless communication, and is used for outputting an alarm prompt when the sensing device 10 detects that a limb is approaching.

That is to say, the sensing device 10 can be fixed on the dressing 30 at the intubation place on the human body (the intubation place is generally covered by pasting the dressing 30, and the dressing 30 is generally non-woven fabric, gauze, etc.), and is used to detect whether the limbs are close, for example When the patient's own hand or someone else's hand approaches the intubation site, the sensing device 10 generates a signal and sends it to the prompting device 20 .

It should be noted that, in the present invention, on the one hand, the sensing device 10 and the prompting device 20 are formed into two independent parts, and only the sensing device 10 is fixed at the intubation of the human body, so that the sensing device 10 part The volume and weight can be made as small as possible, and then when it is fixed on the dressing 30 at the intubation site, the pressure on the intubation site can be reduced as much as possible, and the impact on the intubation site can be avoided. If the induction device 10 and the prompting device 20 are constructed as one, it is not convenient to be fixed at the intubation due to its large volume and weight, and it is easy to generate pressure on the intubation, which will have a greater impact on the intubation. . On the other hand, the wireless communication between the sensing device 10 and the prompting device 20 can remove the constraints of the wired method, and avoid problems such as interference with the patient's limb movements caused by the wired method.

Preferably, at least part of the casing of the sensing device (for example, the side adhering to the dressing) can be made of soft rubber material, so as to avoid injury or other discomfort to the patient's skin.

In some embodiments of the present invention, the sensing device 10 includes a first housing 101 , an infrared sensor 102 , a radio frequency transmitter 103 , a first microprocessor 104 and a first power module 105 .

The first power supply module 105 is electrically connected with the infrared sensor 102 , the RF transmitter 103 and the first microprocessor 104 to provide power for the infrared sensor 102 , the first microprocessor 104 and the RF transmitter 103 .

That is to say, the infrared sensor 102 is arranged on the first housing 101, and is used to detect whether there is a limb approaching, that is, when a patient's hand or other limbs such as hands approach the sensing device 10, the infrared sensor 102 immediately Inductive signals can be generated. The radio frequency transmitter 103 establishes wireless radio frequency communication with the prompting device 20 and can send a radio frequency signal to the prompting device 20 . The first microprocessor 104 is electrically connected with the infrared sensor 102 and the radio frequency transmitter 103. When the infrared sensor 102 detects an induction signal, the first microprocessor 104 can control the radio frequency transmitter 103 according to the induction signal to send the radio frequency signal to Prompt device 20. After receiving the radio frequency signal, the prompting device 20 can output an alarm prompt according to the radio frequency signal.

In this embodiment, on the one hand, the infrared sensor 102 is used to detect whether there is a limb approaching, which can reliably detect the human body, thereby ensuring the accuracy and reliability of the detection. On the other hand, the radio frequency transmitter 103 is used to realize wireless communication with the prompting device 20, which has low power consumption and small size and can meet the transmission requirements.

In some embodiments of the present invention, the prompting device 20 includes a second housing 201 , a radio frequency receiver 202 , a buzzer 203 , a second microprocessor 204 and a second power module 205 .

Wherein, the radio frequency receiver 202 is arranged in the second housing 201 to receive the radio frequency signal sent by the radio frequency transmitter 103 . The buzzer 203 is arranged on the second housing 201 to output the alarm prompt. The second microprocessor 204 is arranged in the second housing 201, and is electrically connected with the radio frequency receiver 202 and the buzzer 203, and is used to control the buzzer 203 to output the alarm according to the radio frequency signal hint. The second power supply module 205 is electrically connected to the RF receiver 202 , the buzzer 203 and the second microprocessor 204 for powering the infrared sensor 102 , the first microprocessor 104 and the RF transmitter 103 .

That is to say, the radio frequency receiver 202 communicates with the radio frequency transmitter 103 in the sensing device 10 , and can receive radio frequency signals sent by the radio frequency transmitter 103 . The second microprocessor 204 is electrically connected to the radio frequency receiver 202. When the radio frequency receiver 202 receives a radio frequency signal, the second microprocessor 204 controls the buzzer 203 to generate an alarm prompt according to the radio frequency signal.

In this embodiment, the radio frequency receiver 202 is used to establish communication with the radio frequency transmitter 103 in the sensing device 10 , which has low power consumption and small size, and can simplify the structure and volume of the prompting device 20 . At the same time, using the buzzer 203 to send out a buzzing sound can make it easier for the escort to hear and take measures in time.

Advantageously, the first power module 105 is a button battery, and the second power module 205 is a lithium battery. Since the induction device 10 is located on the dressing 30, its volume is required to be as small as possible to avoid pressure on the intubation tube. Therefore, the use of a button battery for power supply can reduce the volume and weight of the induction device 10, so as to achieve small size, Avoid the effect of creating pressure on the cannula site. Moreover, it should be noted that the radio frequency transmitter 103 is used for communication, its power consumption is low, and the power supply by button batteries can meet the power supply requirements.

And because the buzzer 203 is used in the prompting device 20 to send a buzzing prompting sound, its power consumption is relatively large. The lithium battery is used for power supply, so that it can meet the power supply demand, and at the same time, it has a relatively larger capacity and a longer service life.

In another embodiment of the present invention, the bottom surface of the first shell 101 is provided with Velcro, and the Velcro is suitable for piercing and fixing on the dressing 30 . In this way, the induction device 10 can be directly punctured and fixed on the dressing 30 by using the Velcro, which is convenient to install and disassemble, and is firm and reliable, and not easy to fall off.
