Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is useful for blood purification treatment, for patients who perform blood component collection in the same position for a long period of time, and for blood donors. The present invention relates to a treatment chair that allows necessary blood components to be collected and treatment to be performed in a comfortable posture with as little fatigue as possible.

[Conventional technology and its problems]

When blood donors or patients hold the same position for long periods of time while collecting blood components or performing other necessary treatments, even healthy blood donors can become fatigued, especially when it comes to patients who require treatment. The fatigue becomes great. Therefore, it is necessary to minimize the fatigue of blood donors and patients when collecting blood components and performing other treatments. To meet this requirement, a special chair has been proposed in which the blood donor or patient sleeps on his or her back. However, this chair simply has an arc-shaped bed with a concave center on the base so that it can swing, and the arc-shaped bed is fixed. Therefore, it becomes painful for blood donors and patients to maintain the same position for long periods of time, and if a patient excretes waste during treatment, it is necessary to provide first aid and clean it, but it is difficult for blood donors and patients to maintain the same position for long periods of time. The solid shape of the material makes this work difficult.

[Means for solving problems]

In view of this, the present invention not only oscillates the arc-shaped bed, but also allows it to rise and fall and become horizontal, making it easier to transfer the bed when providing first aid to patients and blood donors. It has an elevating frame that can be raised and lowered on the base via links and cylinders, two arc-shaped guide rails that are installed opposite to each other on both sides of the upper part of this elevating frame, and a movable frame that can be freely swung on these guide rails. an arc-shaped swinging frame supported by the swinging frame; a cushion that is divided into a plurality of parts and connected to each other via hinges; and a cushion that is vertically mounted on the swinging frame; The main feature is that the shape of the cushion can be arbitrarily adjusted to horizontal or arcuate, and the height of the entire cushion can also be adjusted.

〔Example〕

The present invention will be explained below based on the illustrated embodiments.

In the figure, 1 is a base, 2 is an elevating frame disposed on this base 1, and a bracket 3 is vertically installed at the bottom of this elevating frame.
One end of a link 4 pivotably connected to the upper part of the base via a shaft P1 is fixed to the upper part of the base, and the elevating frame 2 is provided so as to be movable up and down on the base via this link 4. Two sets are placed on each side of the frame. This elevating and lowering operation is performed by one cylinder 5 disposed between the base and the elevating frame.

Arc-shaped guide rails 6 for holding the bed are protruded from both sides of the upper part of the lifting frame, facing each other, and one end of each guide rail is straight, but the entire guide rails are generally arc-shaped. Then, the swing frames 7, 7 are placed thereon. This swinging frame is supported on a guide rail, and wheels 8, 8 are provided on both sides of the frame 7 so as to be able to swing along the guide rail. This wheel may be provided directly on the swinging frame, but in this embodiment, a connecting rod 9 provided to connect two opposing swinging frames 7, 7 is used as an axle, and is provided on this connecting rod 9. There is. Furthermore, the connecting rod 10 without wheels is provided with an auxiliary rod 11 protruding between the opposing swinging frames, and the tip of the auxiliary rod 11 is connected to a link 12 that similarly projects from the connecting rod 9 at a position between the swinging frames. In addition to fixing this link 1
The rod 13a of the cylinder 13 provided on the elevating frame 2 via the bracket B is engaged with the rod 13a of the cylinder 13 provided on the elevating frame 2, and the two connecting rods 9,
10 to share the load and transmit it to the swinging frame so that the swinging frame can be safely and reliably rocked or swung along the guide rail. Note that the same effect can be obtained even if the swing cylinder rod is directly engaged with the connecting rod or the swing frame without using this auxiliary rod.

Furthermore, a lifting device 14 is vertically installed between the other connecting rod 9 and the intermediate connecting rod 10. This has four vertical rods 14a suspended from each connecting rod 9, 10, and one horizontal rod between each of the lower ends of the opposing vertical rods.
4b, 14b are installed in parallel, and a plurality of links 14c are connected to the horizontal rod 14b using a pin axis.
A pantolift is formed by combining them in a letter shape, and a horizontal lifting rod 14d is provided at the top of this pantolift, and a cylinder 15 is installed between both ends of this pantolift, and by operating this cylinder 15, the pantolift can be bent and extended. The lift rod 14d is raised and lowered by moving the lift rod 14d.

The cushion 16 on which the patient rides is divided into a plurality of parts, which are arranged so as to span between opposing elevating frames. The cushions are bendably connected by hinges between the cushions, but are not fixed to the swing frame, and their lower surfaces are supported on the lifting device 14 or the swing frame, and the lower surface of the pillow portion 16a of the cushion is is slidably supported on a part of the swinging frame, and the other cushions are simply placed on the lifting device or on the swinging frame.

[Effect]

FIG. 6 is an explanation of an embodiment in which the cushion is placed in a horizontal state. In this case, when the cylinder 15 of the lifting device is operated, the pantolift extends and the lifting rod 14d rises, lifting the cushion. FIG. 7 shows a state in which the cushion is supported in an arc shape on the swing frame with the pantolift of the lifting device lowered. At this time, depending on the treatment method and in order to reduce patient fatigue, the swing cylinder 13 can be operated to raise or lower the patient's head.
10 to move the swing frame along the guide rail. At this time, if the cylinder rod is protruded from a certain reference point a to point b, the wheels will roll on the guide rail, and the swing frame will swing so that the head side (i.e., the right side in Figures 6 and 7) is lowered. move. On the other hand, if the cylinder rod is moved from the reference point a to point c so as to be depressed, the swinging frame will swing so that its head side is lifted up. If these points b and c are determined in advance by the cylinder stroke, the amount of swing is determined. In this state, that is, when the cushion is in an arcuate shape or when it has reached a horizontal state, if you want to lift the entire cushion, you can operate the lifting cylinder 5 and the link 4 will stand up. An elevating frame pivotally connected to the lever link rises, and the swing frame also rises via a guide rail supported by the elevating frame.
In this way, the height, posture, and shape of the bed suitable for treatment can be appropriately selected.

〔Effect of the invention〕

According to the present invention, the cushion that becomes the bed is divided into many parts and connected via hinges, which are placed on an arc-shaped swinging frame, and this cushion is lifted from below by a lifting device. Because of this design, the cushion can change its shape arbitrarily between horizontal and arcuate shapes, making it easy to transfer patients.During treatment, the cushion can be swung or the entire cushion can be raised and lowered, allowing patients to receive treatment in the most suitable posture. It has the advantage of allowing long-term treatment without causing pain or fatigue to the patient.
