Description

  INDUSTRIAL APPLICABILITY The present invention is an aid in moving a patient, a caregiver, an elderly person, or a care recipient (in the present specification, these are simply referred to as a patient) from a bed in a hospital room to a wheelchair or another bed. The present invention relates to a patient transfer device.

  Self-propelled lift devices, waist belt support devices, fixed ceiling lift devices (for several rooms) and the like are commercially available as patient transfer devices that can easily move a patient between a bed and a wheelchair.

  Although such a patient transfer device is commercially available, the caregiver is still often picking up and moving the patient at the place of care. The lifting operation is to face the front of the patient and make the patient lean on the assistant's chest in a slightly depressed posture, and then move the waist upward to push the chest up. Although it is easy to avoid the risk of low back pain by moving the waist center of gravity reliably, many assistants suffer from low back pain due to differences in height and weight.

  Therefore, a patient transfer device has been proposed in which a plurality of insertion plates with a thin tip and a central arc formed in a gentle arc shape are inserted between a bed and a human body so that a patient who is lying down can be lifted. (See Patent Document 1).

  In addition, as an effort to lengthen the extension of the patient platform of the wheelchair with transfer function, it is configured by an X-shaped frame that can fold the lower frame of the wheelchair to shorten the lateral width, and the patient platform is placed on the lower frame. At the same time, the patient is placed on the bed so that it can move in the direction (the direction approaching the bed), while the patient platform has a two-layer structure consisting of a lower platform and an upper platform, and the upper platform is further moved in the width direction relative to the lower platform It is known that the configuration is made (see Patent Document 2). When performing the patient replacement work in Patent Document 2, first, by folding the X-shaped frame, which is the lower frame of the wheelchair, the patient platform is moved in the width direction (direction approaching the bed) and placed on the bed. After the protrusion, the upper base is further moved in the width direction with respect to the lower base, so that the upper base is moved with respect to the lower base so that the patient base is extended longer. The That is, three rectangular grooves in the width direction are formed on the upper surface of the lower base, and a large number of rollers are accommodated and fitted in the grooves, so that three roller fitting tracks are arranged in parallel on the upper surface of the lower base. ing.

  Furthermore, a wheelchair having a configuration in which a pair of telescopic rails are extended from the wheelchair body onto the bed surface (bed surface) to form a traveling surface of the assisting chair type carrier has been proposed (see Patent Document 3). This wheelchair is placed on a seat-type carrier so as to crawl the person on the bed, align the insertion guide groove with the telescopic rail extended on the bed surface, then pull the carrier as it is, The person being assisted on the bed surface is transferred to the wheelchair body by pulling into the empty seat while sliding or rolling. Thereafter, the telescopic rail is stored in the seat receiving frame.

  However, since Patent Document 1 has a structure in which a patient's body is slid directly on the insertion plate, it may be difficult to ensure a safe and smooth transition of the patient. In addition, since Patent Document 1 has a structure in which a plurality of insertion plates are attached to a girder, it is difficult to reduce the width to fit a wheelchair, and is not suitable for use in transferring a patient between a wheelchair.

  In Patent Document 2, the patient platform is configured in two layers, an upper platform and a lower platform, and the upper platform on which the patient is placed is moved relative to the lower platform, so that a safe and smooth transition of the patient can be ensured. However, since patent document 2 is the structure which transfers to a wheelchair directly from a bed, maintaining the same height, when a patient must be transferred between the bed comprised in arbitrary heights and a wheelchair. May be difficult to transfer due to a step between the two. Further, in Patent Document 2, since the upper base is structured to move relative to the lower base within the width of the patient platform, the distance to move the upper platform is limited by the width of the patient platform. For this reason, it is not suitable for securing a longer movement distance so that the patient does not move as much as possible, or for moving the patient along a curved path that is as reasonable as possible.

Since the above Patent Document 3 is also configured to transfer the patient directly from the bed surface to an empty seat portion of the wheelchair, the patient must be transferred between the bed configured at an arbitrary height and the wheelchair. In some cases, there is a step between the two, making transfer difficult. In addition, the telescopic rail is linearly configured so that it can be stored in the seat receiving frame, and is a form that is linearly transported along the telescopic rail, so it is necessary to secure a longer travel distance or to bend the patient as much as possible. It is not suitable for moving along a track.

The relationship between the main line 74, the second lead-in line 76, and the branch line 77 can be regarded as a form in which the second lead-in line 76 and the branch line 77 are branched from one end 74 c of the main line 74. In this case, the track 6 of the lower track structure 2 has a T-shaped branch that continues from the first transfer position to the second transfer position or to the third transfer position.

  A structure including the upper support structure 3 and the patient platform 4 (hereinafter referred to as “moving structure 78”) is the same as that shown in FIG. Is supported by two upper support structures 3. That is, the support device 5, the lower track structure 2, and the upper support structure 3 are set as one unit, and the patient platform 4 is supported using two units. For this reason, the lead-in line is composed of two parallel lines, and the moving structure 78 is arranged so that the longitudinal direction of the gantry 56 faces the direction perpendicular to the rail.

  When the patient is transported from the first transfer position to the second transfer position, the moving structure 78 starts from the station ST1, which is the first transfer position, and merges with the main line 74 at the turning point EP1. After reaching the turning point EP2 of the inverted L-shaped portion via the curved portion 74b, the direction gradually changes to the second lead-in line 76 side, and then enters the second lead-in line 76 and enters the second transfer position. The station ST2 is reached. When the patient is transported from the first transfer position to the third transfer position, the direction is gradually changed to the branch line 77 side at the turning point EP2 which is a branch part, and the station enters the branch line 77 and is the third transfer position.
