The body support frame 110-1 is a frame in which a cushion mat supporting the patient's head and back is combined. A slide groove is formed in the lower part of the body support frame 110-1 so that one end of the slide frame 120 slides along the longitudinal direction.

The buttock support frame 110-2 is a frame in which a cushion mat that contacts the patient's buttocks and supports the buttocks is combined.

The leg support frame 110-3 is a frame to which a cushion mat supporting the patient's leg is combined. A slide groove is formed in the lower part of the leg support frame 110-3 so that one end of the slide frame 120 slides along the longitudinal direction.

The main frame 110 includes a first rotating part 111 and a second rotating part 112. The main frame 110 includes a first rotating part 111 that rotates in one direction, and a second rotating part 112 that rotates in a direction opposite to the direction in which the first rotating part 111 rotates.

The first rotating part 111 is connected between the body support frame 110-1 and the hip support frame 110-2 and rotates to connect the body support frame 110-1 and the hip support frame 110 of the main frame 110. -2) is in a folded state. The second rotating part 112 is connected between the hip support frame 110-2 and the leg supporting frame 110-3 and is rotated in a direction opposite to the rotation direction of the first rotating part 111 to support the buttocks of the main frame 110. The support frame 110-2 and the leg support frame 110-3 are in a folded state.

The first rotating part 111 and the second rotating part 112 have a limited rotation range and may further include a support member supported from the lower part.

The slide frame 120 has semicircular frames spaced apart from each other with respect to the side surface. Each slide frame 120 has a semicircular shape and is divided into a plurality of pieces, each of which is slidably coupled to the slider 130. The slide frame 120 may be in the shape of hollow pipes with different diameters that can be divided and inserted into one slide frame and the other slide frame.

Each end of the slide frame 120 is slide-coupled to the lower part of the main frame 110. It is preferable that a slide groove is formed in the lower part of the main frame 110 along the longitudinal direction so that the coupling portion where the slide frame 120 is coupled can slide.

The slide frame 120 slides relative to the slider 130 to maintain and support the main frame 110 in a folded or unfolded state.

The slider 130 guides the slide frame 120 so that it can slide. When the slide frame 120 is slid, the slider 130 is fixed to the slider 130 and the slide frame 120 with a fixture 132 such as a fixing pin or bolt. A plurality of fixing holes are drilled in the slide frame 120 and the slider 130 to allow the fixture 132 to pass through.

The slider 130 is provided with a plurality of connection frames 134 facing toward the side of the patient transport mechanism 100. Plates are provided on the connection frame 134 so that items can be placed on them.

A plurality of slider support frames 140 are supported in a vertical direction with respect to the ground at the lower part of the slider 130 and are spaced apart from each other.

The moving frame 150 connects a plurality of slider support frames 140 and supports them to prevent shaking. The moving frame 150 is provided with a plurality of wheels 154 on the lower side of the corner with respect to the plane. The plurality of wheels 154 facilitate the movement of the patient transport mechanism 100.

The mobile frame 150 has wheel attachment portions 151 and 152 each equipped with wheels based on the side surface of the patient transport device 100 and can be expanded and contracted along the longitudinal direction of the patient transport device 100. In addition, the moving frame stretchable portion 153 of the moving frame 150 is also stretchable, so that the overall length can be further reduced. In some cases, the moving frame expansion unit 153 may be a rod-shaped frame that does not expand or contract.

When explaining the operating relationship of the patient transport mechanism 100 according to an embodiment of the present invention with reference to the drawings, the patient is positioned on the main frame 110 to which a plurality of cushion mats are combined, as shown in FIG. 2. .

In places with a large space, the patient is moved while lying down using a plurality of wheels 154 at the corners of the moving frame 150.

As shown in Figure 3, depending on the patient's consciousness or affected area, the patient can be placed in a posture that provides optimal comfort.

The slide frame 120 coupled to the main frame 110 slides and moves in the direction in which the patient's head is located based on the longitudinal direction of the patient transport device 100.

When the slide frame 120 coupled to the body support frame 110-1 slides, the body support frame 110-1 rotates upward in one direction. The body support frame 110-1 and the hip support frame 110-2 connected by the first rotation unit 111 rotate in the opposite direction. In this way, the patient's upper body is transported in a partially upright state.

While transporting a patient, when a space such as an elevator with limited space is reached, the first rotating part 111 of the main frame 110 is moved to the upper side to reduce the overall length of the patient transport mechanism 100, as shown in FIGS. 4 and 5. It rotates in one direction, and the second rotating part 112 rotates in the other direction. In this way, the patient's knees will be bent while the patient is lying down.

The slide frame 120 coupled to the main frame 110 slides and moves in the direction where the patient's head is located based on the longitudinal direction of the patient transport device 100.

The slide frame 120 coupled to the body support frame 110-1 of the main frame 110 slides in the direction in which it extends with respect to the slider 130. At the same time, the slide frame 120 connected to the leg support frame 110-3 slides and moves in a direction that reduces the slider 130. The slide frame 120 supports the main frame 110 and is fixed by a fixture 132.

Accordingly, when the main frame 110 takes the shape of a chair, the patient is seated and the upper body is erected and positioned above the lower body. The length of the wheel attachment portions 151 and 152 of the moving frame 150 is reduced, thereby reducing the plane space it occupies.

Therefore, the patient transport device according to the present invention has a simple and compact structure, enabling patient transport in a state that provides a sense of stability to the patient depending on the patient's condition, and can be transformed to a size and state appropriate for the space size even in a narrow space to transport the patient. It can be transported safely and quickly.
