However, for children, hospital is not specially provided with a hospital bed suitable for children, and for adults to get on and off the bed, especially for patients with inconvenient legs and feet, the two sides of the hospital bed are not provided with corresponding bedrails. However, when a child lies on a hospital bed, the child is better because the child is more comfortable, and particularly when the child sleeps, the child may roll left and right on the hospital bed, and if the child moves to the edge of the hospital bed, the child is easily dropped from the hospital bed onto the ground and falls to the ground to injure the child. At present, in order to solve the above technical problems, parents or nurses of children need to take extra care, and the parents or nurses also take time and waste time and energy.
Disclosure of Invention
The invention aims to provide a protective bed with a lifting bed fence, which is used for preventing children from falling from a bed board when the children move to the edge of the bed board.
In order to achieve the purpose, the technical scheme of the invention is as follows: protection bed with over-and-under type bedrail, including bed board and two headboards, two headboards are located the both ends of bed board respectively, the both sides portion of bed board all is equipped with the guard space, equal vertical sliding connection has the bedrail on the guard space, the bottom on bedrail is equipped with the elevating system who makes the vertical removal of bedrail, still be equipped with the middle part induction zone that is located the bed board middle part on the bed board and the border induction zone that is located bed board both sides portion, the border induction zone is located between guard space and the middle part induction zone, the border induction zone is used for controlling elevating system and rises, the middle part induction zone is used for controlling elevating system and descends.
The working principle of the scheme is as follows: when a person lies on the bed board, the two headboards are respectively close to the head and the feet of the person. The bed fence is used for blocking the two sides of the bed board. The lifting mechanism is used for enabling the bed fence to vertically move, so that the bed fence can extend upwards or retract downwards from the bed board. When children play or sleep on the bed board, when children move to the border induction zone, children's health touching border induction zone for the work of border induction zone, the border induction zone makes elevating system rise, and elevating system drives the bedrail and upwards moves, thereby shelters from the both sides portion of bed board, and children can not drop subaerially from the border of the both sides of bed board. When children get back to the middle part of bed board, children's health can touch the middle part induction zone, and the middle part induction zone begins work, and the middle part induction zone makes the bedrail descend, and the bedrail can not shelter from the both sides border of bed board again to realized the automatic re-setting of bedrail, need not the artifical bedrail that makes the rise and move down, easy operation is convenient, and degree of automation is high. After the bed fence descends, medical staff can conveniently carry out medical care operation on children due to the fact that the edge of the bed board is not blocked by the bed fence.
When adopting above-mentioned technical scheme, this protection bed is adaptable in children and adult, when children moved about or had a rest on the bed board, children can not follow the bed board and fall, improved the security, in addition, when children were when the middle part of bed board, children were far away apart from the border of bed board, and children were in safe within range this moment, and the bedrail can not be followed the bed board and stretched out to be convenient for medical personnel and nurses the operation to children.
Further, the lifting mechanism comprises an air pump and a piston cylinder, a piston is vertically and slidably connected in the piston cylinder, a first tension spring is connected between the piston and the bottom of the piston cylinder, a piston rod is connected to the piston, and the air pump is communicated with the bottom of the piston cylinder. The air pump is used for filling gas into the piston cylinder, when a child touches the edge induction area, the edge induction area enables the air pump to work, when the air pump fills gas into the piston cylinder, the air pressure of the part below the piston is gradually increased, the air pressure pushes the piston to move upwards, the piston drives the piston rod to move upwards, and the piston rod drives the bed fence to move upwards again. When the piston moves upwards, the piston pulls the first tension spring, so that the first tension spring extends to store force, and when the piston cylinder loses air, the first tension spring is used for enabling the piston to move downwards to reset, so that the piston rod drives the bedrail to move downwards to reset.
Further, the border induction zone comprises an outer shell and a conductive block which is vertically and slidably connected in the outer shell, a first pressure spring is connected between the bottom of the conductive block and the bottom of the outer shell, the outer shell comprises an insulating part and a conductive part located below the insulating part, the conductive part can be electrically connected with the conductive block, and the conductive part is electrically connected with the air pump. When children were located the middle part of bed board, children can not touched the border induction zone, and the conducting block is salient from the top of shell body under the elastic force effect of first pressure spring, and the conducting block contacts with insulating part, and the conducting part can not be with the conducting part intercommunication, and the conducting part is the state of opening circuit, so the air pump can not the circular telegram work. When a child is located at the edge of the bed board, the child can extrude the conductive block protruding from the top of the outer shell, the conductive block moves downwards under extrusion, the conductive block is in contact with the conductive part, the conductive part forms a closed passage through the conductive block, current flows through the conductive part and the conductive block to supply power to the air pump, the air pump starts to work, and the air pump charges air into the piston cylinder. When the conducting block received the extrusion, first pressure spring received the extrusion of conducting block and the shrink, when the child left the border induction zone time, the conducting block no longer received children's extrusion, and first pressure spring makes conducting block rebound, and the conducting block separates with the conducting part once more to make the conducting part be the state of opening circuit, so air pump stop work no longer aerifys in to the piston cylinder. Therefore, the automatic control of the edge induction area on the air pump is realized, and the operation is simple and convenient.
Furthermore, the middle induction area comprises a wedge block vertically connected to the middle part of the bed plate in a sliding manner, the bottom of the wedge block is connected with a second pressure spring, a connecting rod is connected to the inclined plane of the wedge block in a sliding manner, a pressure valve is arranged on the piston cylinder, and one end, far away from the wedge block, of the connecting rod can abut against the pressure valve; the connecting rod is connected with a second tension spring. The wedge block can protrude out of the middle part of the bed plate under the action of the elastic force of the second pressure spring. When children move the middle part of bed board, children can extrude convex voussoir for the voussoir moves down, the voussoir extrudees the second pressure spring, when the voussoir moves down, the voussoir offsets with the tip of connecting rod, the voussoir promotes the connecting rod and removes, the one end that the voussoir was kept away from to the connecting rod offsets with the pressure valve on the piston cylinder, thereby make the pressure valve receive pressure and open, the piston receives the effect of the pulling force of first extension spring and moves down and make the gas in the piston cylinder leak out from the pressure valve. When the piston moves downwards, the piston rod drives the bed fence to move downwards to reset. From this, realized that the middle part induction zone controls the bed fence for the bed fence can descend automatically, and degree of automation is high.
