[0002] In clinical nursing, some patients may exhibit risky behaviors such as agitation, self-injury, and falling from bed due to impaired consciousness, mental abnormalities, postoperative delirium, etc., which threaten their own safety and increase the difficulty of nursing. Traditional restraint methods mostly use straps to fix the human body on the bed, but the traditional strapping fixation method is single and difficult to apply to patients of different body shapes. Long-term strapping can easily cause patients to suffer from skin pressure sores, limb numbness and other discomforts.

It should be noted that in a specific embodiment of the present application, a plurality of groups of restraint belts 4 can be set, wherein the plurality of groups of restraint belts 4 are respectively used to tie the patient's chest, arms, abdomen, thighs, ankles, etc., to prevent the patient from moving around on the hospital bed 1 due to insufficient restraint, according to actual needs, such as Figure 1 As shown, the restraints 4 at the arms and ankles can be designed into a Y shape, the open ends of the Y-shaped restraints 4 themselves form a closed loop, and another set of restraints 4 (such as Figure 1 The shape of the restraint belt 4 at the abdomen is shown in the figure) to control the distance between the two restraint belts 4 forming a closed loop and to control the distance between the patient's arms and legs.

[0038] like Figure 4-10As shown, the restraint belt 4 includes a belt body 41, one end of which is fixedly connected to a lock buckle 42, and a lock column 43 is threadedly connected to the lock buckle 42. A through hole for the belt body 41 to pass through is provided on the side of the lock buckle 42 facing the lock column 43, so that the same restraint belt 4 or two restraint belts 4 can be fixed together through the lock column 43; a plurality of pressure sensors 44 are uniformly embedded inside the end of the restraint belt 4 close to the lock buckle 42; a balancing gasket 45 is embedded in the belt body 41, and the balancing gasket 45 fits the plurality of pressure sensors 44 facing the human body one side; an air cabin 46 is also embedded in the belt body 41 along the length direction, the air cabin 46 is located on the side of the balancing gasket 45 facing the human body, the air cabin 46 is half-covered by multiple pressure sensors 44, the air cabin 46 is externally connected to a gas transmission device, the belt body 41 and the air cabin 46 can change in volume with the amount of gas pumped in, it can be understood that the locking column 43 can be used to initially realize the binding of the human body by the restraint belt 4, and the change in the amount of gas inside the air cabin 46 and the change in the volume of the air cabin 46 can further realize the adjustment of the tightness of the binding.

[0039] Specifically, Figure 1-Figure 3 As shown, the bed board 12 includes an upper body support part 121, a fixed part 122, a thigh support part 123 and a calf support part 124, the upper body support part 121 and the fixed part 122 are hinged, the fixed part 122 is fixed to the bed frame 11, the thigh support part 123 and the fixed part 122 are hinged, and the calf support part 124 and the thigh support part 123 are hinged; the bottom side of the bed frame 11 is provided with a support power part 2, and the support power part 2 includes a base 21, a lifting power part 22, an upper body power part The lifting power component 22 is arranged on the base 21 and is hinged to the bed frame 11 for realizing the lifting and lowering of the bed frame 11, the upper body power component 23 is arranged on the bed frame 11 and is hinged to the upper body support part 121 for realizing the angle change of the upper body support part 121, and the lower limb power component 24 is arranged on the bed frame 11 and is respectively hinged to the thigh support part 123 and the calf support part 124 for realizing the angle change of the thigh support part 123 and the calf support part 124.

[0040] Furthermore, a plurality of movable wheels 211 with a self-locking function are provided on the base 21, and a horizontal displacement frame 221 is hinged at the telescopic end of the lifting power member 22, and the horizontal displacement frame 221 is slidably connected to the base 21, and four articulated brackets 222 are symmetrically rotatably connected on both sides of the horizontal displacement frame 221, and the four articulated brackets 222 are respectively rotatably connected to the base 21, and the four articulated brackets 222 are respectively rotatably connected to the bed frame 11 at one end thereof facing the bed frame 11.

[0041] In a specific embodiment of the present application, a mattress 3 is placed on the bed board 12 .

[0042] It should be noted that the lifting power member 22 , the upper body power member 23 and the lower limb power member 24 can be electric push rods in the prior art, and their power supply can be achieved by installing batteries in the base 21 .

[0043] like Figure 8 and Fig. 9 As shown, the belt body 41 includes an outer knitted layer 411, a middle knitted layer 412 and an inner knitted layer 413, and the outer knitted layer 411, the middle knitted layer 412 and the inner knitted layer 413 are sewn to each other, the pressure sensor 44 is embedded in the middle knitted layer 412, the balancing gasket 45 is embedded in the middle knitted layer 412 and crimped to the pressure sensor 44, and the air chamber 46 is embedded in the middle knitted layer 412 and crimped to the balancing gasket 45. It should be noted that, with this design, the exposed parts of the belt body 41 are all knitted layers, so as to achieve breathability during long-term binding and avoid sores on the patient's skin due to airtightness.

[0044] Furthermore, a plurality of positioning holes 414 are provided on the middle knitted layer 412, and a plurality of pressure sensors 44 are embedded in the plurality of positioning holes 414 to form positioning, so as to avoid misalignment of the pressure sensors 44 during the binding process. Two positioning grooves 415 are symmetrically provided on the middle knitted layer 412, and the two positioning grooves 415 are respectively located on both sides of the plurality of positioning holes 414. A middle recess 416 is provided on the side of the middle knitted layer 412 facing the inner knitted layer 413, and a balancing gasket 45 is embedded in the middle recess 416. A side recess 417 is also provided on the side of the middle knitted layer 412 facing the inner knitted layer 413, and an air chamber 46 is embedded in the side recess 417 and the positioning groove 415. This design ensures that the position of the balancing gasket 45 is fixed. At the same time, the existence of the balancing gasket 45 can avoid uneven force on the plurality of pressure sensors 44, which may lead to misjudgment of the binding tightness.

[0045] It should be noted that the balancing gasket 45 can be made of a plastic sheet with a certain hardness, which has an overall deformation to satisfy the belt body 41 to be formed into an arc shape from a strip during the binding process. The overall deformation can also evenly transfer the pressure from the air chamber 46 to the pressure sensor 44.

[0046] Furthermore, a plurality of pressure grooves 418 are evenly arranged on the side of the outer knitted layer 411 facing the middle knitted layer 412. The plurality of pressure grooves 418 correspond one to one with the plurality of pressure sensors 44. Abutment pads 419 are coaxially arranged in the pressure grooves 418. The abutment pads 419 abut against the pressure sensors 44. This design further fixes the positions of the plurality of pressure sensors 44 during the binding process. At the same time, the pressure sensors 44 can better monitor the pressure from the skin direction, thereby improving the accuracy of monitoring and ensuring the suitability of the binding tightness.

[0047] like Figure 4-Figure 7As shown, a fixed cavity 421 and a movable cavity 422 are arranged in parallel in the lock buckle 42, one end of the belt body 41 in which a pressure sensor 44 is embedded is fixed to the fixed cavity 421, the movable cavity 422 and the belt body 41 are slidably connected, and a threaded hole 423 and a hidden hole 424 are coaxially arranged on the side of the movable cavity 422 away from the fixed cavity 421, wherein the diameter of the hidden hole 424 is larger than the diameter of the threaded hole 423.

[0048] Furthermore, the locking column 43 includes a knob 431 , a screw rod 432 and an abutment block 433 which are coaxially fixed in sequence. The screw rod 432 and the threaded hole 423 are threadedly connected, and the abutment block 433 and the hidden hole 424 are matched.

[0049] It should be noted that there are two binding methods in the present application. First, the other end of the same restraint belt 4 is inserted into the movable cavity 422 to form a closed loop; second, one of the restraint belts 4 on both sides of the bed board 12 (this restraint belt 4 has no buckle 42) is inserted into the movable cavity 422 of the buckle 42 on the other restraint belt 4 (this restraint belt 4 has a buckle 42).

[0050] It can be seen that by rotating the knob 431, the screw rod 432 rotates in the threaded hole 423, driving the abutment block 433 to abut against the belt body 41 in the movable cavity 422 and fix the belt body 41, thus forming a preliminary binding.

[0051] like Figure 8 As shown, an air cavity 461 is provided in the air capsule 46, and an air pipe 462 is fixedly connected to one end of the air capsule 46 facing the lock buckle 42. The air pipe 462 passes through the outer knitted layer 411, and two protrusions 463 are symmetrically provided on one side of the air capsule 46 facing the middle knitted layer 412. The shape of the air cavity 461 is the same as the overall shape of the air capsule 46, and the two protrusions 463 are respectively embedded in the two positioning grooves 415.

[0052] It can be seen from this that by connecting the external gas supply equipment and the gas supply pipe 462, and pumping gas into the air cavity 461, the volume of the air chamber 46 will increase due to the increase in the amount of gas inside, and the belt body 41 wrapped around the air chamber 46 will expand synchronously, which will further tighten the binding belt 4. Conversely, when the external gas supply equipment draws the gas in the air chamber 46 outward, the volume of the air chamber 46 and the belt body 41 will decrease synchronously, which will control the tightness of the binding belt 4 that has already formed a preliminary binding. At the same time, the amount of gas is used to apply different pressures to the direction of the pressure sensor 44, so that the pressure sensor 44 can avoid rigid contact with the human body due to binding, thereby increasing the service life of the pressure sensor 44 and reducing the probability of damage to the pressure sensor 44 during the binding process.

[0053] It should be noted that in the specific embodiment of the present application, the outer knitted layer 411, the middle knitted layer 412 and the inner knitted layer 413 of the belt body 41 are made of materials with a certain elasticity, and the air chamber 46 is made of airtight elastic material to meet the volume changes of the belt body 41 and the air chamber 46.

[0054] It should be further explained that the pressure sensor 44 may adopt related existing technologies such as embedded ultra-thin pressure sensors, and a smaller sensor is preferred.

[0055] Embodiment 2, a restraint bed based on an intelligent diagnosis and treatment system of the present application further includes a multi-parameter monitoring module, a central control module and an intelligent diagnosis and treatment system.

[0056] The multi-parameter monitoring module includes a vital signs monitoring unit, a behavior monitoring unit and an environment monitoring unit.

[0057] The vital signs monitoring unit is used to monitor the patient's heart rate, respiration, blood oxygen saturation and body temperature in real time.

[0058] The behavior monitoring unit is used to monitor the patient's activity status, body position changes and abnormal behavior. The behavior monitoring unit includes a high-definition camera and a distributed pressure sensing pad. The high-definition camera is installed on the top of the bed frame 11. It uses a wide-angle lens and infrared night vision function to monitor the patient's activity status and abnormal behavior around the clock; the distributed pressure sensing pad is embedded on the inner side of the mattress 3 and uses multi-point pressure sensing technology to monitor the patient's body position changes and pressure distribution in real time to prevent the occurrence of pressure sores.

[0059] The environmental monitoring unit is used to monitor the temperature, humidity and noise level of the environment around the bed. The environmental monitoring unit includes a temperature and humidity sensor and a noise sensor. The temperature and humidity sensor is installed on the side of the bed frame 11 to monitor the temperature and humidity of the environment around the bed 1 in real time. The noise sensor is installed on the top of the bed frame 11 to monitor the noise level of the environment around the bed 1 in real time.

[0060] The central control module includes a data acquisition unit, a data processing unit and a control execution unit, wherein the data acquisition unit is used to receive data from the restraint belt 4 and the multi-parameter monitoring module, including parameters such as restraint pressure, vital signs, behavioral status and environment; the specific data processing unit adopts an embedded processor and a machine learning algorithm, and the data processing unit is used to perform real-time analysis and processing on the collected data; the control execution unit controls the external gas transmission equipment to pump gas into or out of the gas chamber 46, the lifting and lowering adjustment of the bed board 12 and the angle adjustment of the side fence 13 according to the instructions of the data processing unit, and the central control module is also provided with a manual control panel, and medical staff can manually operate the bed 1 and the monitoring module through the panel.

[0061] The intelligent diagnosis and treatment system includes a patient information management module, a risk assessment module, a personalized restraint program generation module, an intelligent early warning module and a data analysis module, among which the patient information management module is used to store the patient's basic information, medical history, medication status and nursing records; the risk assessment module uses a machine learning algorithm based on patient information and real-time monitoring data to assess the probability of risk events such as self-injury and falling from bed in patients; the personalized restraint program generation module generates a personalized restraint program based on the patient's risk assessment results and individual differences, including the restraint location, restraint strength, restraint time and turning frequency; the intelligent early warning module promptly issues an early warning signal when the monitoring data is abnormal or the patient engages in risky behavior, and reminds medical staff through sound and light alarms and mobile terminal notifications; the data analysis module performs statistical analysis on historical data, generates nursing reports, and continuously optimizes risk assessment models and restraint programs; the intelligent diagnosis and treatment system is also connected to a mobile terminal, through which medical staff can view patient information, monitoring data and early warning information in real time and conduct remote control.

[0062] The following describes the process of restraining a patient by a restraint bed based on an intelligent diagnosis and treatment system according to an embodiment of the present application with reference to the accompanying drawings:

[0063] In actual use, the patient lies on the mattress 3, and the medical staff uses a plurality of straps 4 tied to the bed board 12 to tie the patient's upper and lower body and limbs. Specifically, according to different binding positions, an appropriate binding method is used for binding, and the length of the belt body 41 in the movable cavity 422 is adjusted and the belt body 41 is fixed by using the locking column 43 and the locking buckle 42 to achieve preliminary binding, and then the gas is input into the gas cavity 461 by using an external gas supply device to expand the volume of the entire gas chamber 46 and the belt body 41 outside the gas chamber 46, and vice versa, the volume of the entire gas chamber 46 and the belt body 41 outside the gas chamber 46 is reduced, so as to adjust the tightness of the patient's binding, and the pressure sensor 44 is used in real time to detect the tightness of the patient's binding. The monitored pressure value can effectively control the adjustment of the tightness of the binding, avoiding the situation in which medical staff can only rely on experience to adjust the tightness during the traditional binding process. At the same time, the air chamber 46 changes its volume according to the amount of gas, so that the pressure sensor 44 is subjected to flexible pressure in the direction, which effectively improves the service life of the pressure sensor 44. The design of the balancing gasket 45 can avoid local force imbalance of the pressure sensor 44 during the binding process, avoid inaccuracy in the monitoring results, and improve the accuracy of the binding tightness detection. After binding, the angle of the bed board 12 can be adjusted by lifting the power parts 22, the upper body power parts 23 and the lower limb power parts 24 as needed to change the patient's posture on the mattress 3 to improve the patient's comfort.

[0064] In the related art, the restraint bed based on the intelligent diagnosis and treatment system adopts the pressure sensor 44 to monitor the tightness of the restraint belt 4 in real time, so the protection of the pressure sensor 44 is more important. When restraining the patient, some patients may have agitated behavior due to impaired consciousness, mental abnormalities, postoperative delirium, etc., so the pressure sensor 44 embedded in the belt body 41 may be strongly impacted and damaged, affecting the actual use effect of the pressure sensor 44.

[0065] Embodiment 3, according to some embodiments of the present application, such as Figure 10-12 As shown, the edge of the positioning hole 414 is arranged in a coaxial step shape, a protective ring 5 is embedded in the positioning hole 414, and the pressure sensor 44 is embedded in the protective ring 5.

[0066] Among them, the protective ring 5 includes a coaxially fixed annular outer edge 51 and a limit end 52, the annular outer edge 51 and the limit end 52 form a stepped cylinder and are adapted to the stepped positioning hole 414 to facilitate the fixation of the protective ring 5, and the pressure sensor 44 abuts against the limit end 52.

[0067] Specifically, Fig.11 and Fig.12 As shown, a through hole is provided in the middle of the limiting end 52 , and the through hole is matched with the abutment pad 419 .

[0068] Further, a plurality of through grooves 521 are circumferentially and uniformly arranged on the limiting end 52.

[0069] It should be noted that the protective ring 5 is made of rubber or leather material to ensure that it plays a role in buffering and protecting the pressure sensor 44.

[0070] Thus, it can be seen that the annular outer edge 51 of the protective ring 5 can form a protection on the circumferential side of the pressure sensor 44. The design of the plurality of through grooves 521 on the limiting end 52 makes the limiting end 52 softer while providing protection, facilitating the abutting pad 419 to support and abut against the pressure sensor 44.

[0071] In the related art, for this kind of restraint bed based on an intelligent diagnosis and treatment system, because the restraint belt 4 binds the human body for a long time, especially at the limbs of the patient, the sweat of the patient's skin will penetrate into the belt body 41, causing the pressure sensor 44 to be in a humid environment, which极易 leads to the moisture damage of the pressure sensor 44 or affects the accuracy of the monitoring results.

[0072] Embodiment 4, according to some embodiments of the present application, as Figure 6 and Figure 8 shown, the air chamber 46 forms a U-shape through two protruding parts 463 on one side thereof, and the U-shaped air chamber 46 semi-encloses the pressure sensor 44.

[0073] Among them, the width of the U-shaped air chamber 46 is smaller than the width of the belt body 41.

[0074] Specifically, the protruding part 463 abuts against the outer knitted layer 411.

[0075] Thus, it can be seen that the U-shaped air chamber 46 forms a semi-enclosed state for the pressure sensor 44, and the width of the U-shaped air chamber 46 is smaller than the width of the belt body 41. In this way, after the belt body 41 is soaked by sweat from the skin, the moisture will penetrate from both sides of the air chamber 46 towards the outer knitted layer 411 of the belt body 41 and then dissipate into the air. The U-shaped air chamber 46 plays a certain role in isolating the moisture. At the same time, with the help of the annular outer edge 51 of the protective ring 5, the moisture is further isolated. Even if the sweat dissipates from the outer knitted layer 411 towards the middle knitted layer 412, the annular outer edge 51 can still provide further moisture-proof protection. Moreover, for the U-shaped designed air chamber 46, the gas existing in the protruding part 463 can further form an anti-impact protection for the pressure sensor 44 from the side. This kind of design greatly increases the service life and the use effect of the pressure sensor 44.

[0076] It should be noted that the specific model specifications of the lifting power component 22, the upper body power component 23, the lower limb power component 24 and the pressure sensor 44 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail here.

[0077] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
