Description

Patient transport device between beds {Lateral Patient Transport for hospital bed}

The present invention relates to an apparatus for transferring a patient between beds, and more particularly, to a device capable of automatically loading and unloading a patient so as to move a patient between beds.

When a patient is admitted in a hospital, a bed is provided for stability. In the case of patients with relatively free movement, it is possible to move out of bed, but in the case of patients with disabilities, it may be difficult to get out of the bed. Particularly, in the case of an inability to move, such as a patient who has completed surgery, when they leave the bed, for example, when they need to move to an operating room or examination room, they are in a situation where they are forced to move between beds with the help of another person. The process of transferring a patient from a bed to another bed, for example, a mobile bed, has to be moved together by exerting a large number of personnel and great power, which places a considerable burden on the nursing staff. According to statistics, more than 52% of the nursing staff are found to be suffering from chronic back pain, so a device that helps patients move between beds is needed.

In this regard, Korean Patent Registration No. 0667559 (Announcement on Jan. 11, 2007) discloses a transfer mechanism configured manually, but there is still a burden on the user and the risk of injury to the patient still exists.

Hereinafter, the operation of the inter-bed patient transport apparatus 1 according to the present invention will be described in detail with reference to FIGS. 9 to 14.

9 is an operational state diagram in which the inclination of the upper support plate 120 is adjusted.

As shown in Fig. 9(a), in the bed-to-bed patient transport apparatus 1 according to the present invention, the upper support plate 120 is maintained in a horizontal state in a standby state or a state in which the patient 2 is fully loaded. At this time, the upper side of the upper support plate 120 on which the patient 2 is supported becomes the patient support surface S1.

In addition, as shown in Fig. 9 (b), so that the patient support surface (S1) can be formed on substantially the same plane when the patient 2 is loaded or unloaded, that is, the upper support part 131 and the upper support plate The shape of 120 may be changed on the same plane. At this time, when the tilt adjustment unit 150 is operated to convert the angle of the upper support plate 120, the angle of the side wing 130 changes naturally, and the path of the upper caterpillar 110 formed along it is also naturally changed. Therefore, the patient (2) is inclined to load and unload the patient (2) from the upper side of the bed on which the patient (2) is currently lying, in other words, from the lower support surface (S2) in contact with the bed to the patient support surface (S1). Paths can be formed.

Referring to FIG. 9(c), a concept in which the inclination adjustment unit 150 is driven in a direction opposite to that of FIG. 9(b) is shown. Since the user can select and operate the slope shown in FIGS. 9(b) and 9(c), it is possible to operate freely without being limited to the position or direction of the bed.

Hereinafter, the process of loading the patient 2 will be described in detail with reference to FIGS. 10 and 11.

As shown, first, the movable bed 3 is placed side by side next to the bed 4 on which the patient 2 is lying, and closely adhered (Fig. 10(a)). At this time, the lower caterpillar 210 rotates clockwise based on FIG. 10. Thereafter, the tilt adjustment unit 150 is driven to manipulate the tilt in the direction in which the patient 2 is to be loaded (FIG. 10(b)). After that, the bed-to-bed movable unit 200 rotates the lower caterpillar 210 counterclockwise to move the bed-to-bed patient transfer device 1 to the side of the bed where the patient 2 is lying. The left part of the transfer device 1 is in close contact with the patient 2 (Fig. 10(c)). Thereafter, as shown in FIG. 11(a), the patient transfer unit 100 and the bed-to-bed movement unit 200 together drive an infinite composition so that the side of the bed-to-bed patient transfer device 1 is positioned between the patient 2 and the bed. It becomes burrowed. Here, the lower caterpillar 210 rotates in a counterclockwise direction, and the upper caterpillar 110 rotates in a clockwise direction to penetrate between the patient 2 and the bed. At this time, by adjusting the amount of rotation of the upper caterpillar 110 and the lower caterpillar 210, it is possible to prevent the patient 2 from being excessively moved in the horizontal direction. Eventually, the patient 2 is supported by the upper support plate 120 at a position higher than the upper surface of the bed (Fig. 11(b). After that, the patient 2 is completely separated from the bed, and the patient 2 is the upper support plate). When completely loaded in the area of 120, the tilt adjustment unit 150 is driven clockwise so that the patient 2 can be laid straight in the horizontal direction (Fig. 11(c)). 200) rotates the lower caterpillar 210 in a clockwise direction to move the inter-bed patient transport device 1 and the patient 2 loaded on the patient support surface S1 to a movable bed (FIG. 11B).

Hereinafter, the process of lowering the patient 2 will be described in detail with reference to FIGS. 12 and 13.

12 and 13 are use state diagrams showing the process of placing the patient 2 down. As shown in the figure, first, the movable bed is placed in close contact with the bed on which the patient 2 is to be put down (Fig. 12(a)). Thereafter, the bed-to-bed movement unit 200 rotates the lower caterpillar 210 in a counterclockwise direction to move the bed-to-bed patient transfer device 1 (Fig. 12(b)). Thereafter, the inclination adjustment unit 150 rotates the upper support surface counterclockwise so that the inclination is made to the left in FIG. 12 (FIG. 12(c)).
