Problems solved by technology

[0002] The movable beds used in hospitals can easily push patients from the ward to the operating room or from the operating room to the ward, but most of them use foot brakes or rely solely on the manpower of doctors and nurses to brake.
In the emergency treatment process or when a patient has an emergency, since time is life, when doctors and nurses need to send the patient to the operating room for rescue as soon as possible, they will push the bed quickly, and the corridor design in the existing hospital building, Turning at right angles is unavoidable, so while quickly pushing the bed, it is necessary to turn quickly and safely. It can only be realized by two or more doctors and nurses in front of and behind the bed, which is not only laborious but also unsafe.
In addition, when entering the operating room, doctors and nurses need to brake the hospital bed in time. The use of existing foot brakes is prone to lock-up, resulting in brake failure and increasing unsafe factors.

Embodiment 1

[0020] The invention provides a movable hospital bed, such as figure 1 and figure 2 As shown, including a bed frame 1, one end of the bed frame 1 is provided with a push frame 11, and the bed frame 1 is provided with four bed legs 12, and the bed legs 12 are respectively provided with universal rollers 2 with electromagnetic brakes, each electromagnetic brake The brakes are electrically connected to a brake switch circuit. The bed frame 1 is provided with a built-in power supply 3 and a control chip. The built-in power supply 3 supplies power to the control chip. Each brake switch circuit is electrically connected to the built-in power supply 3 respectively. The control chip controls the brake switch circuit respectively. On or off, the trolley 11 is provided with capacitive touch keys 4 corresponding to the electromagnetic brakes one by one, all capacitive touch keys 4 are electrically connected to the control chip, and the control chip detects the capacitance of the corresp...

Embodiment 2

[0028] The electromagnetic brake that is different from Embodiment 1, such as Figure 4 As shown, in this embodiment, the electromagnetic brake is an electromagnetic eddy current brake. The electromagnetic eddy current brake includes a housing 51 and an excitation coil 54 wound on the housing 51. The housing 51 is hinged with the foot of the bed through a vertical shaft, and the vertical A central hole is provided in the straight shaft, and a conductive rotating pair is arranged between the top of the vertical rotating shaft and the foot of the bed. The first wire is electrically connected between the excitation coil 54 and the conductive rotating pair, and between the brake switch circuit and the conductive rotating pair The second wire is electrically connected, and the universal roller 2 includes a wheel shaft 21 and a wheel body 22. The wheel shaft 21 passes through the center of the excitation coil 54 and is fixedly connected with the housing 51. The wheel body 22 is provi...

Embodiment 3

[0031] The electromagnetic brake that is different from Embodiment 1, such as Figure 5 As shown, in this embodiment, the electromagnetic brake is an electromagnetic friction brake, and the electromagnetic friction brake includes a housing 51, an electromagnetic coil 55 wound on the housing 51, and a brake disc 56 fixed on the housing 51. The body 51 is hinged with the foot of the bed through a vertical shaft, a central hole is provided in the vertical shaft, a conductive rotating pair is provided between the top of the vertical rotating shaft and the foot of the bed, and a first electrical connection is made between the electromagnetic coil 55 and the conductive rotating pair. A second wire is electrically connected between the brake switch circuit and the conductive rotating pair. The universal roller 2 includes a wheel shaft 21 and a wheel body 22. Following the rotation of the wheel body 22 , the armature 26 faces the brake disc 56 . After the brake switch circuit is turn...

Abstract

A mobile hospital bed comprises a bed frame, wherein a hand push frame is arranged at one end of the bed frame, four bed legs are arranged on the bed frame, universal rollers provided with electromagnetic brakes are arranged on the bed legs respectively, each electromagnetic brake is electrically connected with one brake switching circuit, an internal power supply and a control chip are arranged on the bed frame, the internal power supply supplies power to a control chip, each brake switching circuit is electrically connected with the internal power supply, the control chip controls on or off of the brake switching circuits, capacitive touch keys corresponding to the electromagnetic brakes one by one are arranged on the hand push frame and electrically connected with the control chip, the control chip controls operation of the corresponding electromagnetic brakes by detecting whether capacitance of the corresponding capacitive touch keys changes, all capacitive touch keys are arranged in one line, the spacing between every two adjacent capacitive touch keys is not larger than 8 cm, and the spacing between two capacitive touch keys spaced by one capacitive touch key is not smaller than 8 cm.

Description

technical field [0001] The invention relates to a hospital article, in particular to a movable hospital bed. Background technique [0002] The movable sickbed that the hospital uses now can push the patient from the ward to the operating room or from the operating room to the ward very easily, but most of them use foot brakes or rely solely on the manpower of doctors and nurses to brake. In the emergency treatment process or when a patient has an emergency, since time is life, when doctors and nurses need to send the patient to the operating room for rescue as soon as possible, they will push the bed quickly, and the corridor design in the existing hospital building, All can't avoid the right-angle turn, so fast and safe turning while pushing the hospital bed quickly can only be realized by two or more doctors and nurses before and after the hospital bed, which is not only laborious but also unsafe. In addition, when entering the operating room, doctors and nurses need to b...
