Embodiment 2

[0035] Embodiment 2, on the basis of Embodiment 1, in order to make the process of changing the bed sheet more convenient, the hook and the tension hole of the invention are provided with corresponding marking codes, and the left side of the bed sheet and the corresponding tension hole are set to 1, Set the right side of the bed sheet and the corresponding tensioning hole to 2, and the four corners of the bed sheet and the corresponding tensioning hole to 3. When changing the bed sheet, the medical staff or patients can hang the hook on the corresponding Pull tight inside the hole.

Embodiment 3

[0036] Embodiment 3, on the basis of Embodiment 1, the tensioning motor control module is controlled by the single-chip microcomputer U3, and controls the tensioning and loosening of the tensioning rope of the bed sheet by controlling the positive and negative rotation of the tensioning motor, including an optocoupler When PC1 and optocoupler PC2 are tightened, the pin 40 of the single chip microcomputer U3 outputs a low level and connects to the pin 2 of the optocoupler PC1 through the low-voltage frequency converter, and the pin 1 of the optocoupler PC1 is connected to the power supply +5V through the resistor R12, and the optocoupler The pin 3 of PC1 is connected to the ground. At this time, the optocoupler is turned on, and the pin 4 of the optocoupler PC1 is connected to the base of the PNP transistor Q1 through the resistor R13. Since the emitter of the PNP transistor Q1 is connected to the power supply +5V, The collector of PNP transistor Q1 is at high level, connected t...

Embodiment 4

[0037] Embodiment 4. On the basis of Embodiment 1, the timing reminder module is used to send an instruction to the single-chip microcomputer when the set timing time arrives (generally twice a week, which can be set to 72H), and the single-chip microcomputer controls and sends a signal that the bed sheet needs to be replaced. After each replacement, the single-chip microcomputer controls, the time is reset to zero, and the time is reset, including the clock chip U4. Pin 1 and pin 2 of the clock chip U4 are external oscillators for high-precision timing. They are composed of crystal oscillator Y1, capacitor C1, and capacitor C2. The pin 4 of the clock chip U4 is connected to the ground, and the pin 3 of the clock chip U4 is an interrupt output terminal. When the set time is up, it outputs a low level to the single-chip microcomputer, and connects to the pin 9 of the single-chip microcomputer U3 after the pull-up resistor R7, and the clock The pin 5 of the chip U4 is the data te...

Abstract

The invention discloses an equipment device capable of automatically changing a bed sheet. The equipment device comprises a bed body and a control circuit and is characterized in that the lower part of the bed board of the bed body is provided with a fixing frame fixed on the bed body; the fixing frame is provided with a lifting motor; the fixing frame is provided with a supporting frame; the supporting frame is provided with a plurality of vertical supporting rods; the supporting rods pass through the bed board and are in contact with a mattress on the bed board; the output shaft of the lifting motor is connected with the supporting frame through a lifting mechanism to form a structure, capable of vertically moving, of the supporting frame; four corners of the bed board and two sides, on the middle position, of the bed board are respectively provided with a tensioning device; the other end of a rope on each tensioning device is wound on the output shaft of the tensioning motor; the outer edge surface of the mattress is provided with a plurality of U-shaped hoops. The equipment device has the advantages of artful structure and humanized design, the use state of the bed sheet can be automatically detected, patients or medical personnel can be prompted by voice to replace the mattress, in addition, the patients or the medical personnel do not need to bend down, labor intensity is reduced, the bed sheet can better wrap the mattress under a situation that bed sheet flatness is guaranteed, and ultraviolet ray disinfection can be realized.

Description

technical field [0001] The invention belongs to the field of medical equipment, in particular to an automatic bed sheet replacement device. Background technique [0002] At this stage, medical resources are still tight, resulting in a heavy workload for medical staff, especially the frequent replacement of bed sheets. Bedridden patients need to be replaced frequently, and patients need to be replaced after they are discharged from the hospital. For some patients who cannot take care of themselves, bed sheets are easily contaminated , the frequency of replacement is greater, and sometimes when changing bed sheets, patients themselves do not know that their own sheets should be changed, resulting in a heavy workload for medical staff. During the process of changing sheets, it is easier to collect the sheets that need to be replaced, but Putting new sheets on the mattress is a labor-intensive part, because in order to prevent the patient from frequently turning over and causing...
