Description

Technical Field

[0001] This invention relates to the technical field of medical assistive devices, specifically to an intelligent neurosurgical nursing restraint. Background Technology

[0002] For patients with agitated emotions and impaired consciousness, restraint straps are generally used to limit their erratic behavior in order to prevent them from self-harming or harming others. Conventional restraint straps are usually long and narrow. When restraining a patient's limbs, medical staff (restraint personnel) first need to press the patient down and restrain them on the bed, and then another medical staff member (restraint personnel) manually binds the patient's hands and feet with the restraint straps and then ties the ropes to the edge of the bed.

[0003] The following problems often exist in the process of restraining patients with conventional restraint straps: First, patients often need a period of time to calm down after being restrained. During this process, patients continue to struggle, and the knots may loosen, allowing the patients to break free of the restraint straps. Second, since medical staff need to bind the hands and limbs one by one, the restraint of the patient requires medical staff to use their hands to restrain the limbs for a long time until they are properly bound before they can be relaxed, which is not only physically exhausting but also wastes manpower. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems mentioned above by providing an intelligent neurosurgical nursing restraint strap, which can reduce the number of patients who break free due to loose restraint straps and save manpower.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An intelligent neurosurgical restraint belt includes a mounting base, an arc-shaped ring, a belt body, an intelligent sensing system, and a motor. The mounting base is used to fix the belt to a bed. The arc-shaped ring can be inserted into or removed from the mounting base. The belt body is movably inserted into the arc-shaped ring, and the belt body includes a first end and a second end, both of which extend into the mounting base, and the first end is fixed to the mounting base. The intelligent sensing system includes a pressure sensor, a data processing module, a control module, and a wireless communication module. The pressure sensor is installed on the inner side of the arc-shaped ring and is used to sense the pressure exerted on the inner side of the arc-shaped ring when the patient wears it. The data processing module, control module, wireless communication module, and motor are all installed in the mounting base. The data processing module receives data from the pressure sensor and analyzes and processes the data. The control module is connected to the data processing module and receives the result signal processed by the data processing module and issues control commands. The motor is connected to the control module, and the working shaft of the motor is connected to the second end for winding the belt. The wireless communication module is connected to both the control module and the motor and is used for signal transmission between the aforementioned components.

[0006] Furthermore, it also includes a connecting strip, which is a closed loop-shaped strip. The outer surface of the arc-shaped ring is provided with an outer hook, and the connecting strip can be detachably hooked onto the outer hooks of the two arc-shaped rings.

[0007] Furthermore, the intelligent sensing system also includes a heart rate monitoring device, which is installed on the inner side of the arc-shaped ring and is used to monitor the patient's heart rate; the heart rate monitoring device is connected to the data processing module.

[0008] Furthermore, the method of using intelligent neurosurgical nursing restraints includes the following steps: S1 Prepare at least four of the intelligent neurosurgical nursing restraint straps, install two of the mounting seats on the bed edges on both sides of the bed, and install the other two mounting seats on the bed edge at the foot of the bed; S2 The operator restrains the pre-restrained patient to the bed and removes the arc-shaped ring on the corresponding side of the bed edge; S3 After passing the strap through the patient's limbs, fasten the arc-shaped ring at the patient's limbs; S4 The operators on both sides of the bed cooperate to hook the connecting strap onto the outer hook of the arc-shaped ring on both sides of the bed edge; S5 When the pressure sensor detects an increase in pressure and the heart rate monitor detects that the patient's heart rate is higher than normal, the pressure sensor and the heart rate monitor transmit the data to the data processing module. The data processing module processes the data and converts the signal into a digital signal before sending it to the control module. The control module processes the feedback information and sends a control signal to the motor through the wireless communication module to control the motor to tighten the belt. At this time, the patient is confined to the bed. S6 When the pressure sensor detects a decrease in pressure and the heart rate monitor detects that the patient's heart rate has dropped to a normal value, the control module sends a control signal to the motor to control the motor to loosen the belt.

[0009] Furthermore, the data processing module includes a pressure comparison module and a heart rate comparison module. The pressure comparison module is connected to the pressure sensor and is used to compare the changes in pressure on the pressure sensor before and after the patient wears the arc-shaped ring. The heart rate comparison module is connected to the heart rate monitoring device and is used to compare the changes in the patient's heart rate before and after the patient wears the arc-shaped ring.

[0010] Furthermore, the pressure comparison module pre-records a first pressure and a tightening pressure value, where the first pressure is a slight pressure value. When the arc-shaped ring is fastened to the wrist and the patient struggles forcefully, the pressure sensor detects a second pressure. The pressure comparison module compares the second pressure with the first pressure and obtains the difference, i.e., the real-time pressure difference. The heart rate comparison module pre-records a first heart rate, which is the heart rate value when the patient's emotions are stable. When the arc-shaped ring is fastened to the wrist, the heart rate monitoring device detects the patient's real-time heart rate, i.e., the dynamic heart rate.

[0011] Furthermore, the pressure sensor extends along the inner arc length of the arc-shaped ring; the heart rate monitoring device is installed on the inner side of the arc-shaped ring and is offset from the pressure sensor.

[0012] Furthermore, the outer surface of the arc-shaped ring is recessed with a groove that extends along the width direction of the arc-shaped ring. A hook is horizontally disposed in the groove, one end of which is connected to the inner wall of the corresponding end of the groove, and the other end of which extends along the length direction of the groove.

[0013] Furthermore, the number of the outer hooks is several, and the several outer hooks are spaced apart along the arc length direction of the outer surface of the arc-shaped ring.

[0014] Furthermore, the mounting base includes a fixing plate, fasteners, and a working seat. The fasteners are mounted on the fixing plate to fix the fixing plate to the bed frame. The working seat is connected to one side of the fixing plate, and the side of the working seat facing away from the bed frame has a placement groove adapted to the arc-shaped ring. The motor is mounted on the side of the working seat facing the interior of the bed frame.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects: When using the aforementioned intelligent neurosurgical restraint straps, the mounting base allows the straps to be installed on the bed, facilitating restraint procedures for medical staff without affecting the daily use of the bed. When patient restraint is required, two personnel working together can use the corresponding side of the intelligent neurosurgical restraint straps to restrain the patient, saving manpower. The intelligent sensing system adjusts the tightness of the straps based on the patient's limb movements, significantly reducing the likelihood of the patient breaking free due to loosening of the restraints.

[0024] like Figures 1 to 4 As shown, a preferred embodiment of the present invention provides an intelligent neurosurgical restraint belt for restraining a patient with agitated mental disorders to a bed. The belt includes a mounting base 1, an arc-shaped ring 2, a belt body 3, an intelligent sensing system 4, and a motor 44. The mounting base 1 is fixed to the bed. The arc-shaped ring 2 can be inserted into or removed from the mounting base 1. The belt body 3 is movably inserted into the arc-shaped ring 2, and the belt body 3 includes a first end 31 and a second end 32, both of which extend into the mounting base 1, with the first end 31 fixed to the mounting base 1.

[0025] The intelligent sensing system 4 includes a pressure sensor 41, a data processing module 42, a control module 43, and a wireless communication module 45. The pressure sensor 41 is installed on the inner side of the arc-shaped ring 2 and is used to sense the pressure on the inner side of the arc-shaped ring 2 when the patient wears it. The data processing module 42, the control module 43, the wireless communication module 45, and the motor 44 are all installed in the mounting base 1. The data processing module 42 is used to receive the data from the pressure sensor 41 and analyze and process the data. The control module 43 is connected to the data processing module 42 and is used to receive the result signal processed by the data processing module 42 and issue control commands. The motor 44 is connected to the control module 43, and the working shaft of the motor 44 is connected to the second end 32 for winding the tape body 3. The wireless communication module 45 is connected to both the control module 43 and the motor 44 and is used for signal transmission between the aforementioned components.

[0026] In this embodiment, the mounting base 1 includes a fixing plate 11, fasteners 12, and a working seat 13. Fasteners 12 are mounted on the fixing plate 11 to fix the fixing plate 11 to the bed frame; specifically, fasteners 12 are bolts. One end of the fixing plate 11 is detachably screwed with a fastener 12, and the other end of the fixing plate 11 extends towards the bed frame with a mounting hook 14. Another set of fasteners 12 is detachably screwed onto the mounting hook 14. The working seat 13 is connected to one side of the fixing plate 11. The side of the working seat 13 facing away from the bed frame has a placement groove 130 adapted to the arc-shaped ring 2. Specifically, the working seat 13 is integrally formed with the fixing plate 11. The side of the working seat 13 closest to the fixing plate 11 where the mounting hook 14 is located has the placement groove 130 opening towards the mounting hook 14 to facilitate the insertion of the arc-shaped ring 2.

[0027] The motor 44 is installed on the side of the working seat 13 facing the inside of the bed. Specifically, the working seat 13 has an installation space, and a through hole is provided on the side facing the placement groove 130 for the first end 31 and the second end 32 of the belt 3 to pass through. The first end 31 passes through the corresponding through hole and is fixed to the inner wall of the working seat 13 by bolts. The motor 44 is installed in the part of the installation space perpendicular to the fixing plate 11. The working shaft of the motor 44 extends along the width direction of the fixing plate 11. The second end 32 of the belt 3 is fixed to the working shaft of the motor 44. When the motor 44 rotates counterclockwise, the working shaft of the motor 44 can retract the second end 32, thereby tightening the belt 3 on the patient's limbs. A power supply component 47 is installed at the bottom of the installation space. The power supply component 47 can be a rechargeable battery or an external power supply connected by a plug. The power supply component 47 is connected to the motor 44 to supply power to the motor 44. The setting and use of the power supply component 47 is a common technical means in the field and will not be described in detail here.

[0028] In this embodiment, the arc of the arc ring 2 is 240 degrees, and a connecting channel 21 is provided through the arc ring 2. The first end 31 and the second end 32 of the belt body 3 pass through the connecting channel 21 to form a limiting ring 34 and extend toward the mounting base 1. The belt body 33 is provided with an avoidance opening 331 for the first end 31 to pass through. When it is necessary to restrain the patient's limbs, the limbs pass through the limiting ring 34 and the arc ring 2 is fastened to the patient's limbs. Since the arc of the arc ring 2 is 240 degrees, it can ensure that the patient's limbs have a large range of contact with the inner surface of the arc ring 2.

[0029] In this embodiment, the intelligent neurosurgical restraint strap also includes a connecting strap 5, which is a closed loop. An outer hook 22 is provided on the outer surface of the arc-shaped ring 2. The connecting strap 5 can be detachably hooked onto the outer hooks 22 of the two arc-shaped rings 2. Specifically, a groove 22 is recessed on the outer side of the arc-shaped ring 2, extending along the width direction of the arc-shaped ring 2. A hook rod 222 is horizontally arranged inside the groove 22. One end of the hook rod 222 is connected to the inner wall of the corresponding end of the groove 22, and the other end of the hook rod 222 extends along the length direction of the groove 22 to form an outer hook 22 that can limit the connection of the connecting strap 5. When the connecting strap 5 is hooked onto the outer hook 22, it is inserted into and pushed into the groove 22 from the open side of the hook rod 222 and the groove 22. The recessed groove 22 prevents the connecting strap 5 from detaching from the arc-shaped ring 2 due to the patient's body movement.

[0030] In this embodiment, there are several outer hooks 22, which are spaced apart along the arc length of the outer surface of the arc-shaped ring 2. The multiple outer hooks 22 allow the operator to select the nearest outer hook 22 for attaching the hook to the strap 5 during initial restraint of the patient.

[0031] In this embodiment, the intelligent sensing system 4 also includes a heart rate monitoring device 46, which is installed on the inner side of the arc-shaped ring 2 and is used to monitor the patient's heart rate; the heart rate monitoring device 46 is connected to the data processing module 42.

[0032] In this embodiment, the data processing module 42 includes a pressure comparison module 421 and a heart rate comparison module 422. The pressure comparison module 421 is connected to the pressure sensor 41 and is used to compare the changes in pressure on the pressure sensor 41 before and after the patient wears the arc ring 2. The heart rate comparison module 422 is connected to the heart rate monitoring device 46 and is used to compare the changes in the patient's heart rate before and after the patient wears the arc ring 2.

[0033] In this embodiment, the pressure sensing element 41 extends along the inner arc length of the arc-shaped ring 2, and the pressure sensing element 41 adopts a piezoelectric thin film sensor as used in the prior art. The heart rate monitoring element 46 is installed on the inner side of the arc-shaped ring 2 and is offset from the pressure sensing element 41. Specifically, the heart rate monitoring element 46 is installed at the end of the inner side of the arc-shaped ring 2; the heart rate monitoring element 46 adopts a heart rate sensor as used in the prior art. The installation and use of the pressure sensing element 41 and the heart rate monitoring element 46 are well known to those skilled in the art and will not be described in detail here.

[0034] In this embodiment, the method of using the intelligent neurosurgical nursing restraint belt includes the following steps: S1 Prepare at least four intelligent neurosurgical nursing restraint straps. Install two mounting bases 1 on the bed edges on both sides of the bed and install the other two mounting bases 1 on the bed edge at the foot of the bed. Specifically, hook the mounting hook 14 onto the bed edge, fit the top surface of the fixing plate 11 against the bottom of the bed edge, and tighten the fastener 12 to fix the mounting base 1 to the bed. In the initial state, the arc ring 2 and the strap body 3 are both stored in the placement slot 130 and the strap body 3 is in a completely relaxed state.

[0035] S2 The operator restrains the pre-restrained patient to the bed and removes the arc-shaped ring 2 on the corresponding side of the bed edge.

[0036] S3 After passing the strap 3 through the patient's limbs, the arc-shaped ring 2 is fastened to the patient's limbs. Specifically, taking arm restriction as an example, the side with the opening of the outer hook 22 faces the patient's head. After passing the limiting ring 34 through the patient's palm, the arc-shaped ring 2 is fastened to the patient's limbs, which can make the heart rate monitoring device 46 have better contact with the skin.

[0037] The restraint operators on both sides of the S4 bed work together to hook the sleeve 5 onto the outer hook 22 of the arc-shaped ring 2 on both sides of the bed. Specifically, the two restraint operators hold the patient's upper body with one hand and use the other hand to slip the sleeve 5 into the groove 22 through the opening of the outer hook 22. At this time, the patient's upper body is restrained by the sleeve 5. One restraint operator continues to press down on the patient, while the other restraint operator operates the intelligent neurosurgical nursing restraint strap located at the foot of the bed to restrain the patient's feet.

[0038] S5 When the pressure sensor 41 senses an increase in pressure and the heart rate monitor 46 detects that the patient's heart rate is higher than normal, the pressure sensor 41 and the heart rate monitor 46 transmit the data to the data processing module 42. The data processing module 42 processes the data and converts the signal into a digital signal before sending it to the control module 43. The control module 43 processes the feedback information and sends a control signal to the motor 44 through the wireless communication module 45, thereby controlling the motor 44 to tighten the belt 3. At this time, the patient is confined to the bed. Specifically, taking the arm as an example, the pressure comparison module 421 pre-records the first pressure and tightening pressure values, where the first pressure is a slight pressure value. When the arc-shaped ring 2 is fastened to the wrist and the patient struggles, the pressure sensor 41 senses the second pressure. The pressure comparison module 421 compares the second pressure with the first pressure and obtains the difference, i.e., the real-time pressure difference. The heart rate comparison module 422 pre-records the first heart rate, which is the heart rate value when the patient's emotions are stable. When the arc-shaped ring 2 is fastened to the wrist, the heart rate monitoring device 46 detects the patient's real-time heart rate, i.e., the dynamic heart rate. When the real-time pressure difference is greater than the tightening pressure value and the real-time heart rate is much higher than the first heart rate, a tightening signal is generated. The tightening signal is ultimately converted into the counterclockwise rotation of the motor 44, thereby tightening the belt 3. It should be noted that the situation where the real-time heart rate is much higher than the first heart rate is the heart rate defined medically as the heart rate when the patient is emotionally agitated.

[0039] S6 When the pressure sensor 41 senses a decrease in pressure and the heart rate monitor 46 detects that the patient's heart rate has dropped to a normal value, the control module 43 sends a control signal to the motor 44 to loosen the belt 3. Specifically, when the real-time pressure difference is less than the tightening pressure value and the real-time heart rate tends to normal, a tightening signal is generated. The tightening signal is ultimately converted into clockwise rotation of the motor 44, thereby loosening the belt 3.

[0040] In summary, the intelligent neurosurgical nursing restraint belt and corresponding method described in this embodiment can achieve the following technical effects: First, the mounting base 1 allows the intelligent neurosurgical nursing restraint belt to be installed on the bed, which facilitates restraint operations by medical staff without affecting the daily use of the bed.

[0041] Secondly, when it is necessary to restrain the patient, two restraint personnel can work together to use the intelligent neurosurgical nursing restraint belt on the corresponding side to restrain the patient, saving manpower.

[0042] Third, the intelligent sensing system 4 can adjust the tightness of the strap 3 according to the movement of the patient's limbs, which greatly reduces the possibility of the patient breaking free due to the loosening of the restraint strap.

[0043] Fourth, the relaxation and tightening movements of the belt 3 are obtained based on the comparison between the pressure comparison module 421 and the heart rate comparison module 422, which can avoid the situation where the belt 3 tightens due to the patient suddenly swinging their limbs under normal emotional conditions.

[0044] It is understood that the installation position of the heart rate monitoring device 46 is not limited to the end of the inner side of the arc-shaped ring 2 in this embodiment. In other embodiments, the heart rate monitoring device 46 may be installed in the middle of the inner side of the arc-shaped ring 2.

[0045] The above description is a detailed description of the preferred embodiments of the present invention. However, the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications made under the technical spirit of the present invention should fall within the patent scope covered by the present invention.
