Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a medical bed sheet changing robot. Background Art

[0002] Changing bed sheets is a common and tedious task for medical staff and hotel staff. In hospitals, bed sheets must be changed frequently to prevent cross-infection, especially for patients with infectious conditions or on examination beds used repeatedly by multiple patients. In hotels, hotel staff also have to change bed sheets daily and before each new guest arrives. Due to the large number of guest rooms, the burden of changing bed sheets is substantial. Furthermore, each time a bed sheet is changed, bacteria, viruses, and dander attached to the sheets become airborne, potentially causing respiratory and lung infections, asthma, and allergic reactions, to be inhaled by medical staff, patients, hotel guests, and hotel staff.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 6 As shown, this embodiment provides a medical bed sheet changing robot, including a bed sheet storage rod, which includes a push rod 6, a handle 1, a central axis 4, a bearing 2, an outer shell clamp 3 and a wedge 5; one end of the push rod 6 is connected to one end of the handle 1, the central axis 4 is coaxially arranged with the handle 1, and the handle 1 is connected to one end of the central axis 4, the bearing 2 is arranged on the central axis 4, the outer shell clamp 3 is sleeved on the bearing 2, and the wedge 5 is slidably arranged at one end of the central axis 4 and corresponds to the clamping opening end of the outer shell clamp 3.

[0027] In this embodiment, the medical bed sheet-changing robot includes a robot body with a sheet storage rod mounted on it. The robot body is equipped with a path navigation system, a voice prompt system, and a radar emergency avoidance system. It can automatically navigate to a designated bedside and locate its working position.

[0028] The robot body is also provided with a mattress tidying and lifting device, which is used to support the mattress. The mattress tidying and lifting device is an existing product, and its specific structure is not described in detail here.

[0029] An old bed sheet storage box and a new bed sheet storage box are provided in the robot body.

[0030] The housing clamp 3 comprises two arc-shaped columns, and the arc of each arc-shaped column is less than 180 degrees. A clamping opening is formed between one end of the two arc-shaped columns, and a coil spring 10 is provided between the other ends of the two arc-shaped columns.

[0031] The anti-dust film 7 is attached with static electricity. The anti-dust film 7 is a PVA water-soluble laundry film. The anti-dust film 7 can be dissolved in water during the unified washing and become a cleaning agent for the sheets, thereby realizing the automation of the entire process from sheet storage to washing.

[0032] During use, the dust-proof film 7 is first rolled over the old sheet 8. Then, when the user or robot pushes the wedge 5, the wedge 5 is inserted into the gap of the outer shell clamp 3, thereby compressing the spring 10 and opening the clamping opening at the lower end of the outer shell clamp 3. After the opened outer shell clamp 3 contacts the old sheet 8, the wedge 5 is reset and the spring 10 returns to its original state, thus clamping the old sheet 8. After that, the push rod 6 is pushed to rotate the outer shell clamp 3, rolling up the old sheet 8 and the anti-dust film 7 together, and ensuring that the anti-dust film 7 always covers the old sheet 8, thus achieving dust-free storage of the old sheet 8. When replacing the new sheet 9, the new sheet 9 is pre-clamped and wrapped around the outer shell clamp 3. The outer shell clamp 3 extends into the bottom of one end of the mattress supported by the mattress preparation and lifting device. The push rod 6 is pushed to rotate the outer shell clamp 3 to release the new sheet 9. The mattress preparation and lifting device is stored to lower the mattress, pressing the new sheet 9. The push rod 6 is further pushed to rotate the outer shell clamp 3 to lay the new sheet 9. When the mattress reaches the other end, the mattress is raised by inserting the mattress preparation and lifting device into the bottom of the mattress. The push rod 6 is further pushed to rotate the outer shell clamp 3 to the bottom of the mattress. After all the sheets are released, the wedge 5 is pushed to insert the wedge 5 into the gap, thereby compressing the spring 10 and opening the lower end of the outer shell clamp 3. This completes the entire sheet laying process.

[0033] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description.
