Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a mechanism that allows medical examinations to be performed while riding in a wheelchair, especially in a wheelchair. It is related to.

0002

[Conventional technology]

Interviews with patients are usually conducted with the patient seated, but There are relatively few inspection devices that meet this requirement. However, this is not true for devices in the ophthalmology field. Many of them are in the form of seeds. Furthermore, various types of wheelchairs for physically disabled people are known. these The basic structure of currently popular wheelchairs is a base frame with four large and small wheels, It consists of a seating part that is integrally attached to this basic frame and has a backrest. .

[Problem that the idea aims to solve]

However, such wheelchairs cannot be used for examinations in which the wheelchair patient sits on the chair. There are problems with using it as a device chair. In other words, with conventional wheelchairs, it is not possible to move the patient vertically. It is difficult to align the patient and the testing device in the specified relationship if the Ru. In addition, even if the height direction can be adjusted, the inspection device cannot be placed on it. The wheelchair cannot move forward due to interference between the table and the elbow rests, making it impossible to adjust the position in the front and back direction. stomach. For this reason, when testing a patient in a wheelchair, several people must first place the patient in the wheelchair. After that, the patient was placed on an examination chair and the examination was conducted. This kind of method Not only does this require a large number of staff such as nurses, but it is also dangerous for patients in wheelchairs. The special chair attached to the testing device usually does not have armrests, so it is difficult for a wheelchair patient to use the chair. There is a high risk of falling. This invention was devised in view of the above-mentioned shortcomings, and even in seated examinations, patients in wheelchairs can The technical problem is to provide a wheelchair that allows patients to receive medical treatment while seated in the wheelchair.

[Means to solve the problem]

In order to achieve the above purpose, the medical examination wheelchair of the present invention has the following configuration. are doing. That is, (1) A base with wheels and a seat supported by the base and having a backrest at the rear. In a wheelchair having elbow rests supported by a seating part, the seating part is moved up and down. It is characterized by being provided with a driving means.

[0005] (2) The drive means of (1) is provided with a holding mechanism for holding the base, and It is characterized by being placed below the seating area.

[0006] (3) Provide a support that hangs vertically on the base of (1), and make sure that it fits into the support. A support that extends downward from the seating section is arranged to prevent the seating section from moving up and down as the seating section moves up and down. The feature is that the distance between the base and the base can be adjusted.

[0007] (4) The driving means in (1) is a jack.

[0008] (5) The driving source of the driving means in (1) is an electric motor.

[0009] (6) The elbow rest of (1) is characterized in that it is rotatably supported on the seating portion.

【Example】

An embodiment of the present invention will be described based on the drawings. Figure 1 shows one example of a wheelchair. It is an external perspective view, and FIG. 2 is a side view thereof. In the figure, 1 is the base of the wheelchair, which consists of a basic framework consisting of several pipes and It is made up of strong pipes. Front wheels 2 and rear wheels 3 are shown on the basic frame. Not mounted via bearings. Four vertically installed pipes 4a, 4b, 4 It consists of horizontal pipes connecting pipes c and 4d. 5 is the rear wheel 3 It is an integrally formed handle, and by turning the handle 5, the rear wheel 3 is rotated. Turn around.

[0011] Reference numeral 6 denotes a seating portion, and the seating portion 6 is fitted with a vertical support that constitutes a base. As shown in FIG. The length of the distance from 1 is adjusted. Reference numeral 7 denotes a backrest that is integrated with the seating part 6, and the upper end of the backrest is used by a caregiver to hold the wheelchair. A caregiver handle 8 for pushing is attached. In addition, 9 is an elbow rest, and the elbow rest 9 is provided to prevent the patient from slipping off the seat 6. A side plate 10 is provided on the side plate 10. The lower outer side of the side plate 10 is provided on the outer periphery of the seating portion 6. It is in contact with the reinforced reinforcement. The elbow rests 9 and side plates 10 are rotated a little more than 90 degrees clockwise to the back rests 9. It is attached so that it can rotate.

0012 11 is a jack, which is a four-bar link mechanism consisting of four shafts and four nodes. 12 and a rotating shaft 13 having a feed screw. Above the four-bar link mechanism 12 Each lower joint is fixed to the seating part 6 and the base 1, respectively. Rotating shaft 13 rotates Then, due to the action of the feed screw, the left and right internodal distances, and therefore the upper and lower internodal distances, change. Accordingly, the seating portion 6 also moves up and down. In this example, the height from the floor to the seating area is 45 mm. It can be adjusted from cm to 75 cm. 14 is for rotating the rotating shaft 13 It is an auxiliary stick. The auxiliary rod 14 is connected to the rotating shaft 9 via a coupler (not shown). It is connected to the rotating shaft 9 only when the seat is moved up and down. 15 is installed to hold the auxiliary rod 10 on the base 1 when not in use. It is a holder that has been installed.

[0013] In the embodiment with the above configuration, how to use it will be explained next. Approach the testing equipment while the patient is in a wheelchair. The elbow rest 9 gets in the way, If an appropriate distance between the patient and the testing device cannot be obtained, move the elbow rest 9 and side plate 10 to 9. Rotate 0 degrees clockwise. The height positional relationship between the patient and the testing device is Move the inspection device side up and down within the range that can be adjusted using the vertical movement mechanism attached to the device. to align the position. When the patient's height exceeds the vertical adjustment range of the testing device , the auxiliary rod 14 is removed from the holder 15 and connected to the rotating shaft via a coupler (not shown). 9 to rotate the rotating shaft 13. Depending on the direction of rotation of the rotating shaft 13, the upper and lower nodes The distance between the seats and the range in which the seating part 6 moves up and down and can be adjusted by the up and down movement mechanism on the inspection device side. Adjust the height of the seating part 6 to the inside height. At this time, the vertical support that forms the base Since the and the support of the seating part 6 are fitted together, there is considerable strength against rotational force. degree.

[0014] In the above example, a rotary jack is used for the vertical movement mechanism in consideration of cost. However, if a hydraulic jack is used, the burden on caregivers, etc. will be further reduced. In addition, if the vertical movement mechanism is electrically operated, it can be operated by the patient himself/herself. This allows patients to expand their range of activities in daily life. like this However, this embodiment can be modified in various ways, and these modifications also have the same technical concept. It is included within the scope of the present invention.
