Description

[Detailed description of the invention] The present invention relates to an auxiliary pillow device for a medical bed, and its gist is that a main pillow is provided protruding from the rear end of the bed, and auxiliary pillows are arranged in parallel on the outside of the main pillow. The main pillow can be moved up and down, and the auxiliary pillow can be hung down and folded to the underside of the bed, allowing doctors and nurses to perform medical procedures smoothly.

The details of the present invention will be explained below based on the drawings.

FIG. 1 is a perspective view of the main parts of the bed 1, including the main pillow 6,
The left and right auxiliary pillows 6', 6 are held in the same plane, allowing the patient to freely turn over to either the left or right side, allowing a wide range of pillow areas to be used. Folded and held on the bottom surface,
Only the main pillow 6 is raised and maintained at the required height.

Since the left and right auxiliary pillows 6' are mounted and held horizontally on the lower surface of the bed by the same mechanism, the structure of one of them will be explained. As shown in FIG. 3, the mounting rod 2 of the auxiliary pillow 6' is made of a metal plate and has a mounting base rod 2A,
It consists of three parts, the connecting rod 2B and the guide rod 2c, connected in series, and the connecting portions at two places, that is, the front and back ends of the connecting rod 2B, are connected to the sheath part 10 constituted by a dish-shaped metal fitting fixed to the underside of the bed. It is inserted and supported so that it can be drawn out and stored, and maintained in a series state.

The mounting base rod 2A has bolts 3,
3... is fixed to the back surface of the auxiliary pillow, a notch groove 4 is provided in the center from the middle to the front end (connecting rod side), and mounting protrusions 2', 2' are provided on both sides of the front end to protrude like ears. , the rear end mounting protrusion 2 of the connecting rod 2B between the mounting protrusions.
B' is clamped, and a connecting pin 5 is attached passing through each of the attachment protrusions 2', 2B', 2'.

The guide rod 2C at the front end has a mounting protrusion 2 at the rear end.
A mounting protrusion 2B'' at the front end of the connecting rod is sandwiched between C' and 2C' and connected by penetrating support of a connecting pin 6, with a headed protrusion 7 protruding from the front end.
0, a guide groove 12 is bored in the central longitudinal direction, that is, from near the mounting protrusion 2B' of the connecting rod 2B to near the front end of the guide rod, and the headed projection 7 is hooked to the front end of the guide groove. (Refer to the chain line in Figure 3 and Figure 4) 14 is a tightening handle with a screw shaft 14' at its inner end.
passes through the rear part of the mounting base rod 2A of the mounting rod, and by tightening and rotating from the outside, the notch groove 4 of the mounting base rod 2A is cut out.
is tightened to tighten the mounting protrusions 2', 2' at the front end, and press the connecting pin to prevent rotation of the rotating part. In the figure, reference numeral 11 indicates a frame on the lower surface of the bed, and reference numeral 15 indicates an attachment reinforcing portion. In addition, 13 is a main pillow attachment body, 8 is a link guide A, B, C, and D for holding a 4-link mechanism that moves the main pillow 6 up and down almost vertically are each link that constitutes the 4-link mechanism, and E is a link. cover, 9
is a female screw tube that moves the link D in parallel, and when a doctor performs medical treatment, the female screw tube 9 moves on the screw shaft 9', and the link D moves in parallel, and the links A and B connected thereto are moved in parallel. , C stand up and hold the main pillow 6 up as shown in FIG.

The operation of the auxiliary pillow device of the present invention having the above configuration is such that when the auxiliary pillows 6', 6 are gripped by the tightening handle 14 or directly and pulled toward the rear of the bed, the mounting rod 2
is pulled out (at least by the thickness of the auxiliary pillow 6'), and the headed protrusion 7 of the guide rod 2C slides within the guide groove 12 of the sheath part 10 to the rear end and is hooked, so that it is continuous with the mounting base rod 2A. The connecting part of the rod 2B is removed from the inside of the sheath part 10 and protrudes outside the bed, and by loosening the tightening handle, the auxiliary pillow 6' rotates downward about the pin 5 and folds toward the lower surface of the bed. By tightening the tightening handle at a desired location, the mounting protrusions 2', 2', 2
The pressing friction resistance of B′ increases and rotation becomes impossible,
The folded state is maintained. That is, the auxiliary pillow device of the present invention normally holds the auxiliary pillow 6' horizontally by inserting and supporting the mounting rod 2, which is made up of three metal rods rotatably connected in series, into the sheath 10 on the underside of the bed. hold in condition,
When the auxiliary pillow is not needed for treatment, etc., the auxiliary pillow is pulled out in a way that it cannot be pulled out by engaging the guide groove 12 bored in the sheath and the head projection 7, and the auxiliary pillow is immediately rotated and suspended at the connecting part exposed to the outside. It can be folded, and once the folded state is loosened, it can be tightened and held using the tightening handle 14.

The auxiliary pillow device of the present invention having the above-mentioned configuration and operation allows the auxiliary pillow to be easily pulled and folded toward the lower surface of the bed. Therefore, the head, face, or eyes,
Doctors and nurses who perform ear treatment, etc. can get close enough to the patient, the auxiliary pillow does not simply hang down and swing, and does not get in the way. It can be made by tightening and loosening the tightening handle, and there is no need for any complicated mechanism or operation. Despite its simple structure, it works reliably and is an excellent idea with practical value and is suitable as an auxiliary pillow device for medical beds. It is.
