It will not only cause physical and mental harm to patients and affect their quality of life, but also increase the economic burden on patients' families and lead to medical disputes and other problems. The bed exit monitoring alarm device is mainly used for patients with high risk of falling out of bed, dementia, unconsciousness, restlessness, epileptic seizures, lack of autonomy and non-cooperation with treatment. It can immediately remind medical staff after the patient leaves the bed to prevent the patient from falling accidents. In view of this, the traditional device is not perfect and there is no facility to increase the patient's activity space. The pull-out bed exit monitoring alarm device can provide convenience for staff.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0036] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The invention discloses a pull-out bed leaving monitoring alarm device, comprising a bed leaving monitoring mattress assembly, the bed leaving monitoring mattress assembly comprising eight-segment pressure sensitive sensors 1, the pressure sensitive sensors 1 are in the form of soft sheets, the eight-segment pressure sensitive sensors 1 are connected in series to form a sensing pad 2, the outer side of the sensing pad 2 is covered with a waterproof Oxford cloth 3, the waterproof Oxford cloth 3 is detachable, the bed leaving monitoring mattress assembly also comprises a first connecting line 4, one end of the first connecting line 4 is installed at the output end of the sensing pad 2, and the other end of the first connecting line 4 is provided with an alarm assembly.

[0037] The waterproof Oxford cloth 3 is detachable with a zipper, which makes it convenient to remove the waterproof Oxford cloth 3 for cleaning and disinfection to prevent cross infection. When using the sensing pad 2, medical staff can place the waterproof Oxford cloth 3 with the sensing pad 2 on or under the mattress of the hospital bed, or below the patient's hips to shoulders, without restraining the patient's limbs. The patient is located on the top of the sensing pad 2, exerting downward pressure on the sensing pad 2. The sensing pad 2 senses the pressure change and transmits it to the alarm component through an electrical signal.

[0038] See also Figure 1 , Figure 2 , Figure 3 and Figure 4A pull-out bed leaving monitoring alarm device includes an alarm component, the alarm component includes an induction pad signal detection circuit box 5, and the induction pad signal detection circuit box 5 is installed at the other end of the first connecting line 4, a nursing switch 6 is installed at one end of the induction pad signal detection circuit box 5, a second connecting line 7 is installed at one end of the nursing switch 6, a calling device 8 is installed at one end of the second connecting line 7, a third connecting line 9 is installed at one end of the calling device 8, and a bedside calling device panel 10 is installed at one end of the third connecting line 9. The voltage of the induction pad 2 changes with the pressure. The greater the pressure, the greater the voltage. Conversely, the smaller the pressure, the smaller the voltage. The induction pad signal detection circuit box 5 is used to receive the electrical signal generated by the induction pad 2, and output an open circuit signal or a closed circuit signal according to the change of the electrical signal. The induction pad signal detection circuit box 5 controls the calling device 8 and the bedside calling device panel 10 to work or not work by outputting an open circuit signal or a closed circuit signal. The nursing switch 6 can be opened or closed by external pressure to open or close the circuit.

[0039] When the patient is in bed, downward pressure is applied to the induction pad 2, and the voltage of the induction pad 2 increases, which is transmitted to the induction pad signal detection circuit box 5 through an electrical signal. The induction pad signal detection circuit box 5 outputs an open-circuit signal, which is transmitted to the control bedside call panel 10 through the nursing switch 6, the second connecting line 7, and the third connecting line 9, so that the control bedside call panel 10 does not work. When the patient leaves the bed, the pressure on the induction pad 2 decreases, the voltage of the induction pad 2 decreases, and the induction pad signal detection circuit box 5 outputs a closed-circuit signal, and the control bedside call panel 10 receives the closed-circuit signal and starts, notifying the medical staff that the patient has left the bed. When caring for the patient, the patient needs to leave the bed, and the medical staff disconnects the parallel circuit through the nursing switch 6 to temporarily turn off the alarm notification for convenient nursing.

[0040] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The pull-out bed leaving monitoring alarm device includes a calling device 8, which is used to emit a sound to remind the nursing staff. The bedside calling device panel 10 includes a display panel and a control panel. The display panel is used to display the bed position where the sensor pad 2 corresponding to the calling device 8 is located, and the control panel is used to turn off the calling device 8 to continue to emit sound.

[0041] The bedside call panel 10 is installed at the nurse station. When the caller 8 makes a sound, it reminds the medical staff at the nurse station that a patient has left the bed. The medical staff can understand the bed position where the sensor 2 corresponding to the caller 8 is located through the display panel, and then turn off the caller 8 through the control panel.

[0042] See also Figure 1 , Figure 2 and Figure 3The pull-out bed leaving monitoring alarm device includes a pressure sensitive sensor 1. The relevant parameters of the pressure sensitive sensor 1 include:

[0043] Pressure sensing range: 20g~10kg;

[0044] Trigger force: 20g, triggered when the default resistance value is less than 200kΩ;

[0045] Resistance when not triggered: greater than 10MΩ;

[0046] Activation time: less than 0.01s;

[0047] Hysteresis: +10%, RF+-RF- / FR+, 1000g force;

[0048] Response time: less than 10ms;

[0049] Electromagnetic interference EMI: not generated;

[0050] Electrostatic discharge EDS: insensitive;

[0051] Drift: less than 5%, 2.5Kg static load for 24 hours.

[0052] Working principle: Before using the device, you should first check whether there are any problems that affect the use of the device. When the staff needs to use the device, they should first place the waterproof Oxford cloth with the sensor pad 2 under the bed. When the patient leaves the bed, the sensor pad 2 transmits the voltage change to the sensor pad signal detection circuit box 5 through an electrical signal. The sensor pad signal detection circuit box 5 outputs a closed-circuit signal, causing the caller in the bedside caller panel 10 to sound, notifying the medical staff that a patient has left the bed.
