Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to medical nursing equipment, and relates to a mat for preventing bedsores for long-term bed-based patients.

(B) Conventional technology and its problems Bedsores are a skin disease that occurs in patients who have been in bed for a long time. It is thought that bedsores occur due to the moisture of the pressure-contact parts caused by the bed, so the conventional measures to prevent bedsores have been to use bedding that uses fluid pressure, such as air mats, to soften the pressure contact with the bedding as much as possible. In addition, methods have been taken to dry the skin by blowing air from inside the bedding to ventilate the area where the bedding and the skin come into contact.

However, even though bedding that uses fluid pressure has the effect of softening the contact force with the skin, it is only a matter of time and does not last that long, and bedding that uses fluid pressure to emit air has the effect of softening the pressure on the skin. It is difficult to maintain the appropriate level of treatment at all times, and it often causes discomfort to the patient.

(c) Purpose of the Invention The present invention has been made in view of the above-mentioned problems with conventional bedding for preventing floor gaps.
The parts in pressure contact with the skin are replaced alternately so that they are not always the same, and the area in pressure contact with the skin of the replaced parts is reduced to create a pine surge effect that promotes blood circulation to the skin, thereby constantly improving the skin. The purpose of relieving congestion in the pressure-contact area is to provide a mat that does not cause bedsores even for patients who have been in bed for a long time.

(d) Structure of the invention A flexible airtight bag body forms a large number of cylindrical protrusions, and the protrusions are divided into several blocks, each of which is communicated with each other, and air is supplied to each block through an on-off valve. The opening/closing valve is connected to an air pipe connected to a pump, and the opening/closing valve is a mat configured such that when opened, air is sent from the pump to the air pipe, and when closed, the air pipe is opened and closed to the atmosphere. be.

(E) Example The first example of the anti-bedsore mat according to the present invention is shown in a plan view.
As shown in the figure. FIG. 2 is a sectional view taken along the line AA in FIG. 1.

A large number of airtight bag cylindrical protrusions 2 are formed on the surface of a mat 1 made of an airtight bag made of a sheet of soft plastic (such as nylon). In the embodiment, the protrusions 2 have a rectangular cylindrical shape, and the protrusions 2 are arranged in parallel so that their diagonal tops are adjacent to each other. Next to the row of square cylindrical protrusions 21 arranged horizontally, a similar row 22 of square cylindrical protrusions is arranged horizontally such that the diagonal tops of the respective protrusions 2 in that row are adjacent to each other. , the next row of cylindrical protrusions 23 are formed in the same manner. That is, for example, on the top surface of a mat 1 with a horizontal dimension of 85 cm and a vertical dimension of 150 cm, a width of 751 cm. The mat has a planar mesh-like rectangular cylindrical protrusion about 12 ocx in length. In other words, since the cylindrical protrusions 2 and the mat outer periphery 4 on the sides are each airtight bags, there are grooves 5 between the respective cylindrical protrusions 2 and between the mat outer periphery 4 and the cylindrical protrusions 2. Although they are separated from each protrusion 2 and the mat outer peripheral part 4, the protrusion rows 21 and 22
23..., the protrusions of each row are communicated with each other by providing a communication path 6 in the lower part thereof.

A lower air passage 7 is provided along the lower sheet of the mat 1 from the end (diagonal end) of the end protrusion 2a of the protrusion rows 21, 22, 23, and so on. 1
The mat 1 is connected to three air pipes 11, 12, and 13 extending outside and parallel to the longitudinal edges of the mat 1. In other words, one horizontal row (one vertical row in FIG. 1) of protrusions constitutes one block of protrusions, and each block (21, 22, 23,
) are connected, for example, block (21) is connected to air pipe 11, block (22) is connected to air pipe 12, block (23) is connected to air pipe 13, block (24) is connected to air pipe 11, etc. Ru.

With this structure, air is supplied to all of the protrusions 2 from the air pipes 11, 12, and 13 for each block, but air is sealed in the outer peripheral part 4 of the mat in advance through the air inlet 8 at an arbitrary pressure. ing. Air is supplied from the pump to the air pipes 11, 12, and 13 through valves 14, 15, and 16,
A schematic block diagram of this air supply configuration is shown in FIG. 3. The air pipes 11, 12, and 13 are provided with on-off valves 14, 15, and 16, respectively, and an air pipe 20 from the air pump 10 is connected to the valves. The valves 14, 15, and 16 are solenoid valves, and the valves are ON.
(during armature suction).

The air pipe 20 and the air pipe 11 or 12 or 13 communicate with each other and air is supplied to them, and is press-fitted into the protruding part 2 of the block connected to each air pipe. ), a bypass passage provided in the armature communicates with the atmosphere so that the air in the press-fitted block protrusion is discharged to the atmosphere. The valves 14, 15, and 16 are turned on and off in order at regular time intervals. That is, at first, all three valves are opened once and air pressure is applied to all the protrusions 2 to make them protrude.
The subsequent presses are then turned 0FF-ON in sequence. Then, the protrusion block of the air pipe 11 system (21, 24...
) and air pipe 12 system protrusion block (22, 25...
) and air pipe 13 series protrusion block (23, 26...
) will start to descend in sequence. This valve 14/15/1
The sequential OFF/ON of 6 is controlled by the control circuit 9 (timer circuit)
Let it be done. This 0N-OFF control of the valves 11, 12, and 13 is not limited to the above-mentioned 0FF-ON-OFF-ON 111Ji control, but also the 0N-OFF-ON-OFF sequential control can be performed arbitrarily to control each air pipe. The protrusion 2 may be moved up and down by alternately discharging and supplying air to the protrusion block of the system. Furthermore, it goes without saying that the protrusion 2 does not have to be quadrangular but may be circular or triangular.

(F) Effects of the Invention As described above, the patient lies supine on the upper surface of a large number of soft cylindrical bodies, so the pressure points on the patient's skin are many points, and the point portions are Since the changes occur in a sequential and alternating manner, pressure stimulation to the skin is extremely small, and sweating due to long-term pressure is also suppressed.Furthermore, the small protruding tubes on the mat surface are constantly moving in and out, which improves blood circulation in the skin. It is highly effective in preventing bedsores even in patients who are in bed for a long time.
