Description

Examination bed with automatic bed sheet replacement

technical field

The utility model belongs to the field of medical equipment, in particular to an examination bed for automatically changing sheets.

Background technique

At present, the diagnostic bed used in the medical industry is difficult to replace a bed sheet after one person's treatment. After the bed sheets are used by many people, parasites, viruses, pathogens, bacteria, etc. are likely to be left on the sheets. These residues may contain infectious bacteria or viruses, causing infection of patients and endangering health. Under normal circumstances, bed sheets are changed manually. Dozens of patients may lie on a single examination bed a day. If bed sheets are changed manually, the workload is relatively large.

Utility model content

The purpose of the utility model is to provide a bed sheet for automatic replacement of the bed sheet, the bed sheet can be automatically replaced after the patient completes the examination.

The solution of the utility model to solve the above-mentioned technical problem is: a diagnosis bed for automatically changing bed sheets, including a bed body, a bed panel, and a bed sheet, and it also includes a driving roller, a driven roller, a motor, a motor controller, a self-locking switch, Pressure sensor; the bed panel is fixed on the bed body, and the bed sheet is set on the driven roller in the form of a cloth roll to be used. The bed sheet output by the driven roller covers the bed panel, and the terminal part of the bed sheet The winding is arranged on the driving roller; the pressure sensor is arranged inside the bed panel; the motor is connected with the driving roller; the motor controller is connected with the self-locking switch and jointly controls the motor and the pressure sensor.

As a preferred solution, a driving guide shaft and a driven guide shaft are also arranged on the bed body; the bed sheet drawn out from the outer edge of the driven roller goes around the driven guide shaft to cover the entire bed panel, and then goes around the drive guide shaft Winding on the driving drum.

As a preferred solution, the motor is connected to the driving drum through a sprocket.

When the above technical solution is adopted, when the patient’s body leaves the examination bed, the pressure sensor installed inside the bed body monitors the change of the pressure on the bed body, and the pressure sensor generates an electrical signal, which is transmitted to the motor controller , the motor controller starts the motor after receiving the signal, the motor starts to rotate, the motor drives the driving roller to rotate, and the bed sheet connected to the outer layer of the driving roller starts to be wound on the driving roller under the drive of the driving roller, and the bed sheet starts to drive and drive from When the moving roller rotates, the unused bed sheet starts to move and covers the examination bed. When the new bed sheet completely covers the examination bed, turn on the self-locking switch, and the motor stops. The self-locking switch is used to stop the motor and complete the work of changing the bed sheet once.

The utility model has the characteristics of simple and reasonable structure, automatic bed sheet replacement, improved work efficiency, etc., and is especially suitable for relevant inspection and treatment in hospitals.

Detailed ways

Example 1

As shown in Fig. 1, in this embodiment, a medical bed for automatically changing bed sheets includes a bed body 1, a bed panel 2, a bed sheet 3, a driving roller 4, a driven roller 5, a motor 6, a motor controller 7, an automatic Lock switch 8, pressure sensor 9, sprocket 10. The bed panel 2 is fixed on the bed body 1, and the bed sheet 3 is set on the driven roller 5 in the form of a cloth roll to be used, and the bed sheet output by the driven roller 5 is covered on the bed panel 2, and the bed sheet The terminal part is wound and arranged on the driving roller 4; a driving guide shaft 41 and a driven guide shaft 51 are arranged on the bed body 1, and the bed sheet 3 drawn out from the outer edge of the driven roller 5 bypasses the driven guide shaft 51 to cover The whole bed panel 2 is wound on the driving drum 4 around the driving guide shaft 41; the motor 6 is connected with the driving drum 4 through the sprocket 10; the motor controller 7 is connected with the self-locking switch 8 and jointly Control motor 6 and pressure sensor 9, described pressure sensor 9 is arranged on the inside of bed panel, the quantity that sets pressure sensor 9 is two in the present embodiment, certainly the quantity of pressure sensor also can be 3 or 4, when patient When leaving the examination bed, the pressure sensor 9 monitors the pressure change implemented on the bed panel 3, and then the pressure sensor 9 generates an electrical signal, which is transmitted to the motor controller 7 and starts the motor 6, and the self-locking switch 8 is used for Motor 6 is stopped.

When the above technical solution is adopted, when the patient leaves the diagnostic bed, the pressure sensor 9 arranged inside the bed body 1 monitors the pressure change implemented on the bed panel 2, and the pressure sensor 9 generates an electrical signal, and the electrical signal transmits To the motor controller 7, when the motor controller 7 receives the electric signal, the motor controller 7 starts the motor 6 to work, the motor 6 starts to rotate, the motor 6 drives the driving drum 4 to rotate, and the sheet connected to the outer layer of the driving drum 4 3 Driven by the driving roller 4, it starts to wind on the driving roller 4, and the bed sheet 3 starts to drive, so that the driven roller 5 starts to rotate, and the unused bed sheet 3 starts to move and cover the bed panel 2 of the examination bed. When the bed sheet covers the examination bed completely, the self-locking switch 8 is turned on, the motor 6 stops rotating, and the work of changing the bed sheet is completed once.
