Description

Technical Field

[0001] This invention relates to the field of medical and nursing equipment, and in particular to a protective railing with an alarm device and an alarm method thereof. Background Technology

[0002] With the development of industrial technology, modern medical and nursing equipment technology is becoming more and more advanced. For critically ill patients or patients with mental illnesses, these patients moving around on the nursing bed can affect the work of medical staff. Medical staff cannot take care of patients at night. If patients move around, they may fall off the bed. Therefore, it is necessary to install protective devices on the nursing bed.

[0003] Previously, the protective straps on nursing beds could be removed by anyone. If someone other than medical staff removed the protective straps without understanding the patient's condition, it could easily cause harm to the patient. Secondly, the guardrails on nursing beds used to have only one height, and since patients come in different sizes, larger patients needed to have their guardrails replaced with higher ones. Summary of the Invention

[0004] The purpose of this invention is to provide a protective railing with an alarm device and its alarm method. When using the device, after the patient is placed on the bed board, the staff pulls the protective belt out from inside the spring box. The locking strip at the end of the protective belt is inserted into the locking groove. Then, a steel pipe key with an inner triangular hole is taken out and inserted into the keyhole until the inner triangular hole engages with the triangular post. After the ID card and ID reader identify the device, the electromagnetic lock is released, and the triangular post and lock cylinder are rotated until the protective belt is tightly secured in the gap between the lock cylinder and the pressure channel. Each operation of the lock cylinder is recorded by the electromagnetic lock with the operation time and the operator's ID card information, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a guardrail with an alarm device, comprising a bed board, a backrest rotatably mounted on the front end of the bed board, a row of through holes on both the left and right sides of the bed board, a lifting tube slidably inserted into the through holes, the bottom of the lifting tubes welded together by a connecting plate, a torsion tube rotatably mounted on the top end of each lifting tube, a locking assembly between each set of lifting tubes and torsion tubes, guardrails hinged to the top ends of the left and right rows of torsion tubes, three spring-loaded boxes mounted on the top end of the left guardrail, and three lock boxes matching the spring-loaded boxes mounted on the top end of the right guardrail. A protective belt is pulled out from the inside of the box and connected to the lock box. An electromagnetic lock is installed inside the lock box. A tension sensor is also installed in the middle of the protective belt. The electromagnetic lock includes a pressure channel in the middle of the lock box. A lock cylinder is rotatably installed inside the pressure channel. The outer diameter of the lock cylinder is one millimeter larger than that of the pressure channel. A snap-fit ​​groove is provided at the top of the lock cylinder. A clamping groove is provided at the top of the lock box. A snap-fit ​​strip is provided at the end of the protective belt. The snap-fit ​​strip is inserted into the port of the snap-fit ​​groove. The protective belt passes through the snap-fit ​​groove and the clamping groove. Limiting mechanisms are provided at the front and rear ends of the pressure channel. An opening and closing mechanism is provided at the axis of the lock cylinder.

[0006] Furthermore, the locking assembly includes a hinge block at the top of the lifting tube, and a horizontal shaft inserted into the hinge block is rotatably provided at the bottom of the torsion tube. Both the horizontal shaft and the hinge block are provided with interlocking insertion holes, and a steel bar mechanism is provided in the middle of the insertion holes.

[0007] Furthermore, the steel bar mechanism includes a bolt, the bottom end of the lifting tube is provided with an internal thread that matches the bolt, the top end of the bolt is provided with a steel bar, and the steel bar is inserted inside the lifting tube and the torsion tube.

[0008] Furthermore, the tension sensor is connected to the nurse station display, and when the tension value of the tension sensor is zero, the buzzer of the nurse station is triggered.

[0009] Furthermore, the limiting mechanism includes limiting rings at the front and rear ports of the pressure channel, and one side of the limiting ring is provided with a notch that mates with the clamping groove.

[0010] Furthermore, the opening and closing mechanism includes a triangular prism at the axis of the lock cylinder, a steel sleeve on the side wall of the lock box, the steel sleeve engaging with the outside of the lock cylinder and the triangular prism, a keyhole matching the triangular prism being provided in the middle of the steel sleeve, an electromagnetic lock mutually attracting each other being provided inside the lock cylinder and on the side wall of the lock box, the triangular prism being equipped with a steel tube key with an inner triangular hole, the steel tube key having an L-shaped outline, an identification card being provided inside the steel tube key, and an identification reader matching the identification card being provided inside the lock cylinder.

[0012] S1. After placing the patient on the bed board, the staff pulls the protective belt out from inside the spring box. The locking strip at the end of the protective belt is inserted into the locking slot. Then, the steel pipe key with the inner triangular hole is taken out and inserted into the keyhole until the inner triangular hole is locked onto the triangular post. After the ID card and ID reader recognize the information, the electromagnetic lock is released. The staff then begins to twist the triangular post and the lock cylinder post until the protective belt is locked in the gap between the lock cylinder post and the pressure channel. Each operation of the lock cylinder post is recorded by the electromagnetic lock with the operation time and the operator's ID card information.

[0013] S2. When the bolts and steel bars are rotated out, the torque tube can start to rotate and level relative to the lifting tube, and the lifting tube can also rise and fall relative to the bed board, so that the height of the guardrails on both sides of the bed board can be adjusted to two levels.

[0014] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this invention are:

[0015] Firstly, after placing the patient on the bed board, the staff pulls the protective belt out from inside the spring box. The locking strip at the end of the protective belt is inserted into the locking slot. Then, a steel pipe key with an inner triangular hole is taken out and inserted into the keyhole until the inner triangular hole is engaged with the triangular post.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides, for example Figures 1-6The protective railing shown includes a bed board 1, with a backrest 2 rotatably mounted at the front end of the bed board 1. A row of through holes is provided on both the left and right sides of the bed board 1, through which lifting tubes 3 slide. The bottoms of the lifting tubes 3 are welded together via connecting plates 301. A torsion tube 4 is rotatably mounted at the top of each lifting tube 3. A locking assembly is provided between each set of lifting tubes 3 and torsion tubes 4. Guardrails 5 are hinged to the tops of the left and right rows of torsion tubes 4. Three spring boxes 6 are mounted at the top of the left guardrail 5, and three lock boxes 9 matching the spring boxes 6 are mounted at the top of the right guardrail 5. A protective belt 7 is pulled out from the inside of the spring box 6 and connected to the lock box 9. An electromagnetic lock is provided inside the lock box 9. A tension sensor 8 is also provided in the middle of the protective belt 7. The electromagnetic lock includes a pressure channel in the middle of the lock box 9. A lock cylinder 11 is rotatably mounted, with an outer diameter one millimeter larger than the pressure channel. The top of the lock cylinder 11 has a snap-fit ​​groove 1101, and the top of the lock box 9 has a clamping groove 902. The end of the protective belt 7 has a snap-fit ​​strip 701, which is inserted into the snap-fit ​​groove 1101. The protective belt 7 passes through the snap-fit ​​groove 1101 and the clamping groove 902. Limiting mechanisms are provided at the front and rear ends of the pressure channel, and an opening and closing mechanism is provided along the axis of the lock cylinder 11. After the patient is placed on the bed board 1, the staff pulls the protective belt 7 out from inside the spring box 6. The snap-fit ​​strip 701 at the end of the protective belt 7 is inserted into the snap-fit ​​groove 1101. The lock cylinder 11 and the protective belt 7 are rotatably locked in the gap between the lock cylinder 11 and the pressure channel. The protective belt 7 can then be pulled between the two guardrails 5, achieving a portable and detachable effect.

[0027] The locking assembly includes a hinge block 302 at the top of the lifting tube 3, and a horizontal shaft inserted into the hinge block 302 at the bottom of the torque tube 4. Both the horizontal shaft and the hinge block 302 are provided with interlocking insertion holes 401. A steel bar mechanism is provided in the middle of the insertion holes 401. The torque tube 4 can be rotated and laid flat relative to the lifting tube 3. The lifting tube 3 can also be raised and lowered relative to the bed board 1. As a result, the height of the guardrails on both sides of the bed board 1 can be adjusted to two positions. For larger patients, the torque tube 4 can be erected.

[0028] The steel bar mechanism includes a bolt 10. The bottom end of the lifting tube 3 is provided with an internal thread that matches the bolt 10. The top end of the bolt 10 is provided with a steel bar 1001. The steel bar 1001 is inserted inside the lifting tube 3 and the torque tube 4. When the bolt 10 and the steel bar 1001 are rotated out, the torque tube 4 can start to rotate and flatten relative to the lifting tube 3.

[0029] The tension sensor 8 is connected to the nurse station display. When the tension value of the tension sensor 8 is zero, it triggers the buzzer at the nurse station. When the protective belt 7 breaks, the value of the tension sensor 8 will return to zero, and then the tension sensor 8 will send a signal to the buzzer at the nurse station, and the buzzer will start to sound to notify the medical staff.

[0030] The limiting mechanism includes a limiting ring 901 at the front and rear ports of the pressure channel. One side of the limiting ring 901 is provided with a notch that mates with the clamping groove 902. The limiting ring 901 can fix the position of the lock cylinder 11 and prevent the lock cylinder 11 from falling out of the lock box 9.

[0031] The opening and closing mechanism includes a triangular prism 1102 at the axis of the lock cylinder 11. A steel sleeve 12 is provided on the side wall of the lock box 9. The steel sleeve 12 is engaged with the outside of the lock cylinder 11 and the triangular prism 1102. A keyhole 1201 matching the triangular prism 1102 is provided in the middle of the steel sleeve 12. An electromagnetic lock that attracts each other is provided inside the lock cylinder 11 and on the side wall of the lock box 9. The triangular prism 1102 is equipped with a steel pipe key with an inner triangular hole. The outline of the steel pipe key is L-shaped. An identity card is provided inside the steel pipe key. An identity reader matching the identity card is also provided inside the lock cylinder 11. When the staff takes out the steel pipe key with the inner triangular hole, inserts it into the keyhole 1201 until the inner triangular hole is engaged with the triangular prism 1102. After the identity card and identity reader recognize each other, the electromagnetic lock is released, and the triangular prism 1102 and the lock cylinder 11 can be rotated. Each operation of the lock cylinder 11 is recorded by the electromagnetic lock with the operation time and the operator's identity card information, which achieves the effect of preventing unauthorized personnel from operating the lock.

[0032] Includes the following steps:

[0033] S1. After placing the patient on the bed board 1, the staff pulls the protective belt 7 out from the inside of the spring box 6. The locking strip 701 at the end of the protective belt 7 is inserted into the locking slot 1101. Then, the steel pipe key with the inner triangular hole is taken out and inserted into the keyhole 1201 until the inner triangular hole is locked onto the triangular column 1102. After the identity card and identity reader recognize it, the electromagnetic lock is released. The staff begins to twist the triangular column 1102 and the lock cylinder column 11 until the protective belt 7 is locked in the gap between the lock cylinder column 11 and the pressure channel. Each operation of the lock cylinder column 11 will be recorded by the electromagnetic lock with the operation time and the operator's identity card information.

[0034] S2. When bolt 10 and steel bar 1001 are rotated out, torque tube 4 can start to rotate and flatten relative to lifting tube 3, and lifting tube 3 can also rise and fall relative to bed board 1, so that the height of the guardrails on both sides of bed board 1 can be adjusted to two positions.

[0035] Working principle: After placing the patient on the bed board 1, the staff pulls the protective belt 7 out from inside the spring box 6. The locking strip 701 at the end of the protective belt 7 is inserted into the locking groove 1101. The locking cylinder 11 and the protective belt 7 are rotated and locked in the gap between the locking cylinder 11 and the pressure channel. The protective belt 7 can then be pulled between the two guardrails 5, achieving a portable disassembly effect. The torque tube 4 can then rotate and flatten relative to the lifting tube 3. The lifting tube 3 can also rise and fall relative to the bed board 1. Thus, the height of the guardrails on both sides of the bed board 1 can be adjusted to two positions. For larger patients, the torque tube 4 is erected. When the bolt 10 and steel bar 1001 are rotated and pulled out, the torque tube 4 can be raised and lowered relative to the lifting tube 3. When the protective belt 7 breaks during the initial rotation and leveling process, the tension sensor 8 will return to zero. The tension sensor 8 then sends a signal to the buzzer at the nurses' station, which will sound to notify medical staff. The limit ring 901 can fix the position of the lock cylinder 11, preventing it from falling out of the lock box 9. Staff take out a steel pipe key with an inner triangular hole and insert it into the keyhole 1201 until the inner triangular hole engages with the triangular pillar 1102. After the ID card and ID reader recognize the key, the electromagnetic lock is released, allowing the triangular pillar 1102 and the lock cylinder 11 to be rotated. Each operation of the lock cylinder 11 is recorded by the electromagnetic lock, including the operation time and the operator's ID card information, effectively preventing unauthorized personnel from operating the lock.
