Description

Technical Field

[0001] The utility model relates to the field of hospital supplies, in particular to an anti-pollution structure for a public wheelchair. Background Art

[0002] To facilitate mobility for patients with limited mobility within hospitals, many hospitals now have public wheelchairs available for borrowing, greatly facilitating both medical treatment and inpatient mobility. However, the large number of patients using these wheelchairs can easily lead to wheelchair contamination. Patients may leave blood, vomit, bodily fluids, and even excrement on the wheelchairs after use. This can carry pathogens, posing a risk of disease transmission, and can also make subsequent users reluctant to use them.

[0003] To ensure wheelchair cleanliness, many hospitals have established wheelchair management systems, such as requiring staff to clean and disinfect wheelchairs during the morning and day shifts. However, this significantly increases the workload; it also prevents timely cleaning and disinfection after a patient's use, leaving the next patient with the potential for a contaminated wheelchair.

[0004] Placing disposable mats on wheelchairs can provide protection, but ordinary mats cannot be fixed stably on the wheelchair and are easily moved. In addition, how to place and manage disposable mats so that patients or medical staff can easily access them is also a problem to be solved. Utility Model Content

DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 7 As shown, the anti-pollution structure of a public wheelchair includes a cloth roll holder 1 and a cloth roll 2; the cloth roll holder 1 includes a fixed cylinder 11, a pad 16, a fixed cylinder cover 12, a core shaft 15, a cloth pressing structure 13 and a mounting structure 14; the two ends of the fixed cylinder 11 are respectively an open end and a closed end, and a cloth pulling outlet 111 is provided on the side of the fixed cylinder 11, and the cloth pulling outlet 111 is arranged along the length direction of the fixed cylinder 11; the core shaft 15 is coaxially arranged with the fixed cylinder 11 and connected to the fixed cylinder 11; the cloth roll 2 includes a sleeve 22 and a cloth assembly, the sleeve 22 is sleeved on the core shaft 15, and the cloth assembly includes multiple cloths The cloth 21 is folded into a rectangle and arranged in a row, adjacent cloth pads 21 are connected and the connections can be torn apart, and the cloth pad assembly is rolled on the sleeve 22; the fixed cylinder cover 12 covers the open end of the fixed cylinder 11; the pad 16 and the cloth pad pressing structure 13 are respectively located on both sides of the cloth pad outlet 111 and are both connected to the fixed cylinder 11, the cloth pad pressing structure 13 includes a rotatable roller 131, a cloth pad 21 is pulled out from the cloth pad outlet 111, the roller 131 presses the pulled cloth pad 21 on the pad 16 and can release the pressure; when the cloth pad 21 is unfolded, it can cover the backrest, seat and armrests of the wheelchair 3.

[0028] When the utility model is used Figure 8 As shown, the cloth roll holder 1 is installed on the backrest of the wheelchair 3 through the mounting structure 14. Then the cloth roll 2 is loaded into the fixed cylinder 11. Specifically, the fixed cylinder cover 12 is opened, the cloth roll 2 is inserted from the open end of the fixed cylinder 11, and the sleeve 22 is mounted on the core shaft 15. Then a cloth 21 is pulled out from the cloth pull outlet 111, pressed by the roller 131, and then the fixed cylinder cover 12 is closed. The cloth 21 of the present invention needs to be used once or replaced after a period of use. After all the cloths 21 contained in the cloth roll 2 are used up, the cloth roll 2 can be replaced according to the above method.

[0029] Before use, the patient holds the exposed mat 21 and pulls it out until the adjacent mat 21 is exposed and pressed by the roller 131. The mat 21 can then be torn off, pressing the adjacent mat 21 with their hands. The mat 21 is then unfolded and placed over the backrest, seat, and armrests of the wheelchair 3. Any blood, vomitus, body fluids, or even excremental contaminants produced by the patient after use will adhere to the mat 21 and not the wheelchair, thus protecting the wheelchair. After use, the mat 21 can be removed. If no blood, vomitus, body fluids, or excremental contaminants remain on the mat 21, the mat 21 can be replaced daily. This demonstrates the beneficial effects of the present invention in ensuring wheelchair cleanliness and preventing the spread of disease.

[0030] The cloth roll holder 1 is mounted on the backrest of the wheelchair 3 via the mounting structure 15, providing convenient access to the cloth 21. The cloth 21 is rolled up and the cloth roll holder 1 is used to store the cloth roll 2, ensuring proper storage of the cloth roll 2. Adjacent cloths 21 are connected, and the connection can be torn apart. The roller 131 presses the pulled-out cloth 21 against the pad 16, ensuring that the cloth 21 can be pulled out and torn off for use with a little force. This also prevents the cloth 21 from being easily pulled out, thus preventing the cloth 21 from being accidentally pulled out and wasted.

[0031] Preferably, the mat cloth pulling outlet 111 extends to the open end of the fixed cylinder 11. In this way, before the mat cloth roll 2 is installed in the fixed cylinder 11, the mat cloth 21 can be pulled out for a while; when the mat cloth roll 2 is installed in the fixed cylinder 11, the pulled-out mat cloth 21 passes through the mat cloth pulling outlet 111, which makes it more convenient to expose a part of the mat cloth 21 when installing the mat cloth roll 2 so that it can be pulled out for subsequent use.

[0032] The specific cloth pad pressing structure 13 includes a V-shaped frame 132, a rotating shaft 134 and a torsion spring 133. The middle part of the V-shaped frame 132 is hinged to the fixed cylinder 11. The rotating shaft 134 and the torsion spring 133 are respectively located on both sides of the hinge point between the V-shaped frame 132 and the fixed cylinder 11. The rotating shaft 134 is connected to the V-shaped frame 132, and the roller 131 is mounted on the rotating shaft 134. The torsion spring 133 is located between the fixed cylinder 11 and the V-shaped frame 132. The torsion spring 133 causes the roller 131 to press the cloth pad 21.

[0033] By pressing the end of the V-shaped frame 132 away from the fixed cylinder 11, the end of the V-shaped frame 132 closer to the fixed cylinder 11 rises, creating a gap between the fixed cylinder 11 and the backing plate 16, allowing the cloth 21 to pass through the gap between the fixed cylinder 11 and the backing plate 16. When the V-shaped frame 132 is released, the elastic force of the torsion spring 133 causes the V-shaped frame 132 to rotate, thereby pressing the fixed cylinder 11 against the cloth 21.

[0034] Furthermore, it is preferred that the fixed cylinder cover 12 has an annular flange 121, which is sleeved on the core shaft 15. This is beneficial to improving the stability of the core shaft 15.

[0035] The mounting structure 14 is used to mount the cloth roll holder 1 on the wheelchair 3. Specifically, the mounting structure 14 and the cloth pressing structure 13 are connected to opposite sides of the fixing tube 11. Two mounting structures 14 are provided, one at each end of the fixing tube 11. The mounting structure 14 includes a mounting seat 141 and a pressing plate 142. Both the mounting seat 141 and the pressing plate 142 have arcuate grooves disposed opposite each other. The pressing plate 142 is connected to the mounting seat 141 via fasteners.

[0036] The left and right sides of the backrest of a common wheelchair 3 are provided with hollow tubes arranged in the vertical direction, and the upper ends of the hollow tubes are bent to form handles for the wheelchair 3. The above-mentioned mounting structure 14 is used to fix the cloth roll holder 1 on the hollow tube, and the mounting seat 141 and the pressing plate 142 can clamp the hollow tube under the action of the fastener force. Since the upper end of the hollow tube is bent backward to form a handle for pushing the wheelchair 3, the fixing tube 11 should avoid the handle to prevent the handle from affecting the insertion of the cloth roll 2. If the mounting structure 14 is as Figure 3 As shown, the cloth roll holder 1 should be located on one side of the wheelchair 3 to avoid the handle. Figure 4 As shown, the pad roll holder 1 can be located behind the wheelchair 3 .

[0037] The specific structure of the pad 21 is preferably as follows Figures 6 to 8 As shown, the padding 21 includes a backrest padding 211, a backrest front padding 212, a seat padding 213, an armrest padding 214, a second tether 215, a first tether 216 and a third tether 217; the backrest padding 211, the backrest front padding 212 and the seat padding 213 are arranged in sequence, and a handle hole 218 is provided at the connection between the backrest padding 211 and the backrest front padding 212; the number of the armrest padding 214 is two, and the two armrest paddings 214 are respectively located on the left and right sides of the seat pad 213; there are two second straps 215, and the two second straps 215 are respectively connected to the left and right sides of the rear end of the backrest pad 211; there are two first straps 216, and the two first straps 216 are respectively connected to the two sides of the front end of the seat pad 213; the two armrest pads 214 are connected to the third strap 217, and the third strap 217 is close to the outer edge of the armrest pad 214.

[0038] like Figure 10 As shown, after the mat 21 is unfolded, the back mat 211, the front back mat 212, and the seat mat 213 respectively cover the backrest, front backrest, and seat of the wheelchair 3. The two armrest mats 214 respectively cover the two armrests of the wheelchair 3. The handles of the wheelchair 3 pass through the handle holes 218, and the second tether 215 is tied to the wheelchair legs at the front of the wheelchair 3. This prevents the back mat 211, the front back mat 212, and the seat mat 213 from moving. The third tether 217 is tied to the armrests of the wheelchair 3 to prevent the armrest mat 214 from moving.

[0039] The pad 21 can be made of nonwoven fabrics, has low cost, and is applicable to disposable use. The two pads 21 adopt a point-break connection mode, so that they can be torn apart.
