Description

[Technical field]

[0001] The present invention relates to an electric wheelchair with an oxygen inhalation function. [Background technology]

[0002] Such an electric wheelchair is described, for example, in JP 2001-70356 A (Patent Document 1), and has an oxygen tank mounted on the side or rear of the electric wheelchair. A tube of an oxygen inhalation device such as an oxygen mask or cannula is connected to an oxygen outlet provided at the top end of the oxygen tank. Then, oxygen is supplied to a person by wearing the oxygen inhalation device.

[0003] However, if the oxygen tank is placed on the side or back of the electric wheelchair, the electric wheelchair becomes larger and more difficult to control. Therefore, we considered installing a compact oxygen generator under the seat of the electric wheelchair. When the tube of the oxygen inhaler is connected to this oxygen generator, a long flexible tube is extended vertically.

[0004] This can cause objects to get caught in the tube while the electric wheelchair is moving. Also, if the oxygen inhalation equipment is dropped, it will fall to the floor and the user will not be able to easily retrieve it. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2001-70356 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] The problem to be solved is how to place the oxygen generator under the seat of the electric wheelchair and how to supply oxygen from the oxygen generator. [Means for solving the problem]

[0007] In the electric wheelchair (1) of the present invention, an oxygen generator (8) is removably arranged under the seat (2), and removable electrical connection parts (12a, 12b) for supplying electricity from a power source (7) of the electric wheelchair to the oxygen generator, and removable fluid connection parts (13a, 13b) for flowing oxygen from the oxygen generator to an oxygen inhaler are provided under the seat, and an oxygen flow path (16) from the fluid connection parts passes through the inside of the electric wheelchair body (2, 3), extends from the underside of the seat to the upper side of the seat, and exits from the electric wheelchair body above the seat to be connected to the oxygen inhaler (8).

[0008] In addition, a storage section (11) for storing the oxygen generator is provided below the seat, and this storage section is provided with an electrical connection section and a fluid connection section, and when the oxygen generator is pushed into the storage section, the electrical connection section and the fluid connection section may be connected.

[0009] The oxygen flow path passes through the inside of the backrest of the electric wheelchair body, extends to the upper part of the backrest, and then exits to the outside from the upper part of the backrest where an oxygen inhaler is connected. This oxygen inhaler may have an oxygen discharge nozzle (18b) at the tip of a flexible tube (18a) that is freely bendable and can maintain its position when bent. Effect of the Invention

[0010] According to the present invention, since the oxygen generator is disposed under the seat, the electric wheelchair can be made compact and easy to operate. Since the oxygen generator is detachably provided, the oxygen generator can be removed from the electric wheelchair when the user is away from the electric wheelchair and can be used at a location away from the electric wheelchair. Furthermore, since the oxygen flow path passes through the inside of the electric wheelchair body and extends from the underside of the seat to the upper side of the seat, there is no risk of objects getting caught in the oxygen flow path while the electric wheelchair is moving. Since the oxygen inhaler is connected to the oxygen flow path above the seat, even if an oxygen mask or cannula is used as the oxygen inhaler, the end of the tube is located above the seat, and even if the oxygen inhaler is dropped, the passenger can easily retrieve the oxygen inhaler by pulling up the tube of the oxygen inhaler.

[0011] Furthermore, in the case where the electrical connection section and the fluid connection section are attached and detached by pushing the oxygen generator into the storage section, the attachment and detachment of the oxygen generator can be completed in approximately one operation, making it easy.

[0012] Furthermore, if the oxygen flow path extends to the top of the backrest and exits from the top of the backrest to the outside, and an oxygen inhaler is connected to it, and this oxygen inhaler is equipped with an oxygen discharge nozzle at the end of a flexible tube that is flexible and can maintain its position when bent, then when a passenger gets on or off the electric wheelchair, they can support their body by placing their hands on the seat or armrests, without being hindered by the oxygen inhaler or the like. [Brief description of the drawings]

[0013] [Figure 1] FIG. 1 is a side view of an electric wheelchair according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a partially cutaway side view. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The objective of making the electric wheelchair with oxygen inhalation function smaller has been achieved by detachably placing the oxygen generator under the seat. EXAMPLES

[0015] Next, an embodiment of the electric wheelchair of the present invention will be described with reference to Figures 1 and 2. Figure 1 is a side view of an embodiment of the electric wheelchair of the present invention. Figure 2 is a partially cutaway side view.

[0016] Like a normal chair, the electric wheelchair 1 has a seat 2, a backrest 3, and armrests 4. The armrests 4 are provided with a control lever 6 for controlling the electric wheelchair 1. A drive power source 7 for driving the electric wheelchair 1 and an oxygen generator 8 are built into the underside of the seat 2.

[0017] The oxygen generator 8 is stored in a storage section 11 provided below the seating section 2. At the back of the storage section 11, there are provided an output terminal 12a of an electrical connection section 12 that supplies electricity from the traveling drive power source 7, and an input terminal 13b of a fluid connection section 13 that receives oxygen from the oxygen generator 8. Meanwhile, at the tip of the oxygen generator 8, there are provided an input terminal 12b of the electrical connection section 12 and an output terminal 13a of the fluid connection section 13, and when the oxygen generator 8 is pushed into the storage section 11, the electrical connection section 12 and the fluid connection section 13 are connected.

[0018] The oxygen that has flowed into the fluid connection part 13 passes through the oxygen flow path 16 and reaches the backrest part 3. The oxygen flow path 16 is provided inside the seat part 2 and the backrest part 3, which are the main body of the electric wheelchair 1, and extends from the underside of the seat part 2 to the upper side of the seat part 2 and exits to the outside from the left edge of the upper part of the backrest part 3.

[0019] An oxygen inhaler 18 is connected to the upper end of the oxygen flow path 16. The oxygen inhaler 18 is equipped with a flexible tube 18a connected to the oxygen flow path 16, and an oxygen discharge nozzle 18b provided at the tip of the flexible tube 18a. The flexible tube 18a is widely used for microphone and lighting stands, and is flexible and can maintain its position when bent.

[0020] When inhaling oxygen in the electric wheelchair 1 configured in this manner, the oxygen generator 8 is pushed into the storage section 11 and installed. Then, the electrical connection section 12 and the fluid connection section 13 are connected, and oxygen is discharged from the oxygen discharge nozzle 18b of the oxygen inhaler 18. Then, oxygen is supplied to the passenger. When the passenger gets off the vehicle while on the road, etc., and wants to use the oxygen generator 8 in a location away from the electric wheelchair 1, the oxygen generator 8 is pulled out of the storage section 11 and connected to a household power source or the like for use. The oxygen generator 8 is configured so that it can be turned on and off using a remote control, smartphone, etc.

[0021] As described above, oxygen inhaler 18 is connected to oxygen flow path 16 provided inside the main body of electric wheelchair 1. Therefore, there is no risk of objects getting caught in oxygen flow path 16 while electric wheelchair 1 is moving, compared to the case where oxygen inhaler 18 is directly connected to oxygen generator 8 below seating section 2.

[0022] Even if an oxygen mask, cannula, or the like is used as oxygen inhaler 18, the tube thereof will be connected to oxygen flow path 16 above seating portion 2. Therefore, the end of the tube of oxygen inhaler 18 is located above seating portion 2, and even if oxygen inhaler 18 is dropped, the passenger can easily retrieve oxygen inhaler 18 by pulling up the tube of oxygen inhaler 18.

[0023] Although the embodiment of the present invention has been described above in detail, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the gist of the present invention described in the claims. Modifications of the present invention are exemplified below. (1) If an electric wheelchair has a seat, it does not necessarily have to have a backrest or armrests.

[0024] (2) The oxygen inhaler is equipped with a flexible tube and an oxygen discharge nozzle attached to the tip of the flexible tube, but the configuration can be modified as appropriate, and it is also possible to adopt an oxygen mask, cannula, etc. In addition, the flexible tube can be freely bent and can hold its position when bent, and the structure can be modified as appropriate as long as it can flow oxygen.

[0025] (3) The arrangement and structure of the oxygen inhaler can be changed as appropriate. For example, oxygen inhaler 18 is attached to the left edge of the upper part of backrest 3, but it can also be attached to the right edge. It can also be attached to other locations, such as armrest 4. (4) The structure and installation method of the oxygen generator can be selected appropriately. For example, the oxygen generator disclosed in Patent No. 6860197 is known. [Industrial Applicability]

[0026] Since it can be made compact and easy to maneuver, it is ideal for use in electric wheelchairs with oxygen inhalation functions. [Explanation of symbols]
