The alarm reminder unit sends an alarm reminder to the nurse on duty, and then the nurse goes to check the patient's condition. The higher first baffle makes the thermal imaging sensing probe in the fixed plate higher, avoiding the thermal imaging sensing probe from being blocked, and combined with the tilt setting of the thermal imaging sensing probe, the thermal imaging sensing probe has a large sensing range, which improves the accuracy of sensing, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a nighttime thermal imaging patient monitoring bed, comprising a bed body, a first stopper provided at one end of the bed body, a second stopper provided at the other end of the bed body, a fixing plate provided at the top of the first stopper, a thermal imaging sensing mechanism provided in the middle of the fixing plate, and a bed board adjustment mechanism provided in the middle of the bed body;

[0007] The thermal imaging sensing mechanism includes a thermal imaging sensing probe, which is obliquely arranged in the middle of the fixed plate.

[0013] The technical effects and advantages of the present invention are as follows:

[0014] 1. The present invention sets a thermal imaging sensor probe to perform thermal imaging detection on patients resting on the bed at night, and sends the detection information to the nurse station processor. When there is no patient and the patient's thermal imaging information is detected, the timer in the nurse station processor counts the patient's departure time. Within the set time, if the patient does not come to the bed, the nurse station processor uses the alarm reminder unit to send an alarm reminder to the nurse on duty, and then the nurse goes to check the patient's condition.

In addition, through the socket arrangement of the rotating frame and the telescopic rod, in conjunction with the limit block and the spring, when the patient is resting, the patient's body presses on the second bed board, driving the second bed board to rotate, so that the telescopic rod retracts into the rotating frame and compresses the spring. At this time, the pressure block on the straight rod contacts the pressure sensor on the limit block, that is, the pressure sensor is used to sense whether the patient is on the bed. In conjunction with the above-mentioned thermal imaging sensing probe, false alarms are avoided and the accuracy of alarm reminders is improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The present invention provides Figure 1-3 The nighttime thermal imaging patient monitoring bed shown in the figure comprises a bed body 1, a first stop frame 2 being provided at one end of the bed body 1, a second stop frame 3 being provided at the other end of the bed body 1, a fixing plate 4 being provided on top of the first stop frame 2, a thermal imaging sensing mechanism being provided in the middle of the fixing plate 4, and a bed board adjustment mechanism being provided in the middle of the bed body 1;

[0025] The thermal imaging sensing mechanism includes a thermal imaging sensing probe 5, which is obliquely arranged in the middle of the fixed plate 4. The output end of the thermal imaging sensing probe 5 is connected to a nurse station processor 6 for receiving and processing information. The output end of the nurse station processor 6 is connected to a timing unit 7 for starting timing after receiving information that the patient has left the bed. The output end of the timing unit 7 is connected to an alarm reminder unit 8 for reminding the nurse on duty to check on the patient.

[0026] The specific implementation method is as follows: the thermal imaging sensing probe 5 on the fixed plate 4 collects the patient's thermal imaging information and sends the detection information to the nurse station processor 6. When there is no patient and the patient's thermal imaging information is detected, the timer 7 in the nurse station processor 6 counts the time from the moment the patient leaves the bed. Within the set time, the patient does not come to the bed. The nurse station processor 6 uses the alarm reminder unit to send an alarm reminder to the nurse on duty, and then the nurse goes to check the patient's condition. The higher first baffle 2 makes the thermal imaging sensing probe 5 in the fixed plate 4 positioned higher to avoid the thermal imaging sensing probe 5 being blocked, and combined with the tilt setting of the thermal imaging sensing probe 5, the sensing range is large, which improves the accuracy of sensing.

[0027] like Figure 2-6 The shown embodiment is a nighttime thermal imaging patient monitoring bed, wherein the bed board adjustment mechanism includes a first bed board 9, which is arranged on one side of a bed body 1, and a second bed board 10 is arranged on the other side of the bed body 1. Slide rods 11 are arranged on both sides of the bottom of the bed body 1, and a sliding frame 12 is arranged between the two sliding rods 11. A hydraulic push rod 13 is arranged on one side of the sliding frame 12, and a rotating frame 14 is arranged on the other side of the sliding frame 12. A telescopic rod 15 is arranged between the rotating frame 14 and the bottom of the second bed board 10, and a pressure detection device is arranged between the rotating frame 14 and the telescopic rod 15.

[0028] Furthermore, the height of the first stop frame 2 is higher than that of the second stop frame 3 , the first bed board 9 is fixedly connected to the bed body 1 , the second bed board 10 is hinged to the first bed board 9 , and stop rods are provided on both sides of the first bed board 9 , and both stop rods are fixedly connected to the second stop frame 3 .

[0029] Furthermore, the sliding rod 11 is slidably connected to the sliding frame 12, the two sliding rods 11 are fixedly connected to the hydraulic push rod 13 through a fixed frame, the rotating frame 14 is hinged to the sliding frame 12, the rotating frame 14 is set to be U-shaped, and the telescopic rod 15 is hinged to the second bed board 10.

[0030] The specific implementation method is as follows: when adjusting the second bed board 10, the hydraulic push rod 13 pushes the sliding frame 12 to slide on the sliding rod 11. Since the first bed board 9 and the second bed board 10 are hingedly connected, the second bed board 10 rotates around the hinge. When the rotating frame 14 rotates, the second bed board 10 does not apply a reverse force to the rotating second bed board 10, that is, the spring 17 will not be compressed, thereby adjusting the rotation angle of the second bed board 10 and facilitating the use of the bed. When the second bed board 10 rotates, when there is a patient resting on the second bed board 10, the patient's body presses the second bed board 10 to rotate, compressing the spring 17, but does not affect the hydraulic push rod 13 pushing the sliding frame 14, thereby driving the rotation adjustment of the second bed board 10.

[0031] Furthermore, the pressure detection mechanism includes a limit block 16, which is arranged between the two telescopic rods 15, a spring 17 is arranged between the limit block 16 and the rotating frame 14, a fixed rod 18 is arranged at the bottom of the rotating frame 14, a straight rod 19 is arranged in the middle of the fixed rod 18, a pressure block 20 is arranged on the surface of the straight rod 19, and a pressure sensor 21 is arranged on the surface of the limit block 16.

[0032] Furthermore, the rotating frame 14 is sleeved with the telescopic rod 15 , the straight rod 19 passes through the limit block 16 , the pressing block 20 matches the pressure sensor 21 , and the pressing block 20 is made of rubber material.

[0033] The specific implementation method is as follows: when the patient is resting, the patient's body presses on the second bed board 10, driving the second bed board 10 to rotate, so that the telescopic rod 15 is retracted into the rotating frame 14, and the limit block 16 compresses the spring 17. At this time, the limit block 16 is lowered, and the straight rod 19 further extends into the limit block 16. The pressure block 20 on the straight rod 19 contacts the pressure sensor 21 on the limit block 16, that is, the pressure sensor 21 is used to sense whether the patient is on the bed, and the pressure block 20 is made of rubber material. The elastic deformation of the rubber is used to avoid crushing the pressure sensor 21. In conjunction with the thermal imaging sensing of the thermal imaging sensing probe 5, an additional method of monitoring the patient is realized, that is, the two patient monitoring methods simultaneously trigger the information that the patient is not detected on the bed. After the set time of the timing unit 7 is exhausted, the nurse station processor 6 uses the alarm reminder unit 8 to send an alarm reminder to the nurse on duty, and then the nurse goes to check the patient's condition, avoiding false alarms and improving the accuracy of the alarm reminder.

[0034] Working principle of the present invention:

[0035] Refer to the instruction manual Figure 1-3 When performing thermal imaging monitoring on patients resting on the hospital bed at night, the thermal imaging sensor probe 5 on the fixed plate 4 collects the patient's thermal imaging information and sends the detection information to the nurse station processor 6. When there is no patient and the patient's thermal imaging information is detected, the timer 7 in the nurse station processor 6 counts the time from the moment the patient leaves the bed. If the patient does not get on the bed within the set time, the nurse station processor 6 uses the alarm reminder unit 8 to send an alarm reminder to the nurse on duty, and then the nurse goes to check the patient's condition. The higher first stop frame 2 makes the thermal imaging sensor probe 5 in the fixed plate 4 higher, avoiding the thermal imaging sensor probe 5 from being blocked, and with the tilt setting of the thermal imaging sensor probe 5, the sensing range is large, which improves the accuracy of the sensing;

[0036] Refer to the instruction manual Figure 2-6 When adjusting the rotation angle of the second bed board 10, the hydraulic push rod 13 is used to push the sliding frame 12 to slide on the sliding rod 11, driving the rotating frame 14 to rotate, and cooperating with the telescopic rod 15 to push the second bed board 10 to rotate, thereby adjusting the rotation angle of the second bed board 10 and facilitating the use of the bed; when the patient is resting, the patient's body presses on the second bed board 10, driving the second bed board 10 to rotate, so that the telescopic rod 15 retracts into the rotating frame 14, and cooperates with the limit block 16 to compress the spring 17. At this time, the pressure block 20 on the straight rod 19 contacts the pressure sensor 21 on the limit block 16, that is, the pressure sensor 21 is used to sense whether the patient is on the bed, and cooperates with the above-mentioned thermal imaging sensor probe 5 to avoid false alarms and improve the accuracy of alarm reminders.
