(Problem to be Solved by the Invention) However, even if such a method is used, the current situation is that it cannot be expected to be as effective. Moreover, this problem is essentially caused by the pine l
It was hoped that a drastic solution would be established to solve this problem.

The present invention has been made in view of this situation, and is a new air pine for a clinical examination bed that can be comfortably used even under special conditions of medical diagnosis ('t) - Device and air pine 1 - The purpose is to provide the main body.

[Structure 1 of the invention (Means for solving the problem) The structure of claim 1 of the present invention for achieving this object is as follows:
Air bag-type air pine 1 ~ Provide the required amount of ventilation holes on the patient's recumbent surface of the main body, and install an air conditioner capable of supplying air at the desired temperature and humidity into the air pine 1 ~ main body. Connected to the air pine 1 to device for clinical examination bed consisting of -C.

Further, the structure of claim 2 is constructed of double skins separated by a gap from the patient's recumbent surface, and each skin is provided with a large number of ventilation holes formed at different positions. It is located on the air mat 1~main body of the air mat device.

(Function) The function of claim 1 of the present invention based on this configuration is to maintain the patient lying on the bed in a comfortable position during diagnosis with air EE, and to maintain appropriate temperature and humidity. The key to providing air to the patient is to maintain a comfortable temperature and humidity level for the patient.

Another advantage of the second aspect of the present invention is that by arranging the ventilation holes twice, the resistance of the air that can flow upward from the air pine 1 to the main body is increased, thereby saving the amount of air supplied.

(Example) Hereinafter, a detailed explanation of the present invention will be given based on the illustrated example.

FIG. 1 is a schematic perspective structural view of an air mat device according to an example of the present invention, and FIG. 2 is a schematic cross-sectional view taken along the line AA wedge section in FIG.

In the figure, air pine 1 to device 1 which are one embodiment of the present invention
0 is a rectangular air bag-type air mat body 11 with a size large enough for a normal adult patient to lie down, and as shown in the cross-sectional view of FIG. A large number of ventilation holes 12 are uniformly formed on the upper surface 1a of the mat body 11, and one end surface 11b of the mat main body 11.
an appropriate air pipe 13 connected to the pipe 13;
and an air conditioner 14 that supplies air maintained at a predetermined temperature and humidity to the air pine 1 to the main body 11 through the air pine 1 to the main body 11.

In this case, the flexible skin member constituting the bag of the air mat body 11 has an air-blocking property made of a suitable high-strength cloth material coated with rubber, such as the one used in the Hovergraph 1~. skin material is used.

The air conditioner 14 also includes an appropriate heating device 14a that can adjustably heat the outside air taken in to a desired temperature and humidity, and an appropriate heating device 14a that can adjustably heat the outside air taken in to the desired temperature and humidity, and the air conditioner 14a, which heats the air heated to the desired temperature and humidity at an appropriate pressure. It is configured as an air conditioner equipped with an appropriate blower pump 14b that can adjust the amount of air that can be sent into the air pine 1 to the main body 11, and the structure itself is configured using known technology. . In a preferred embodiment, an air pressure sensor 15 is installed at an appropriate location on the air mat main body 11 side, and the air volume of the air conditioner 14 can be controlled based on a signal from the sensor 15.

(2) The number and distribution of the vent holes 12 are set to values such that the ejected air hits the body of the patient lying on the air mattress body 11 on average, and Opening 1] area and total opening area are the air conditioner 14
The ventilation holes 12 are determined based on the amount of air supplied into the air mat body 11 from above, the weight of the patient lying on the pine 1 to the body 11, the contact area between the mat body 11 and the patient's body, etc.
It is determined in relation to the air handling @ (escape amount) from the group.

Therefore, it is possible to assume the patient's weight etc. using a statistical method, set the individual and total opening areas of the ventilation holes 12R1 by plugging them based on the assumption, and determine the amount of air supplied at a constant rate or in stages. It is also possible to set the individual and total area of the pores 12 groups to be constant and to change the amount of supplied air using the air pressure sensor 15 described above.

Next, an example of the operation of the air pine 1 to the device 10 of the illustrated embodiment having such a configuration will be explained.

Prior to diagnosis, first operate the air conditioner 14 to send air maintained at a predetermined temperature and humidity into the air pine 1 to the main body 11 to inflate the air pine 1 to the main body 11 4. In this state, the air pine l to the main body 11 Since a relatively large amount of air is supplied from the group of ventilation holes 12, the operation of the air conditioner 14 is set in advance to a low level.

Then, when the patient gets on the air mat 1 to the main body 11 and lies down on the upper surface 11a thereof, the operation of the air conditioner 14 is returned to the specified operating state, and the patient's position on the upper surface 11a of the mat main body is determined by the pressure of the supplied air at the time of diagnosis. Make sure to set it to height. In this case, air at a predetermined temperature and humidity is drawn upward not only from the 12 groups of ventilation holes located at locations that are not in contact with the patient's body, but also from the 12 groups of ventilation holes located at locations that are in contact with the patient's body. Therefore, even if the medical equipment inevitably generates heat and the diagnosis takes a long time, the patient does not have to sweat.

What is shown in FIG. 3 is a partial schematic sectional view showing another example of the air pine 1 to the main body, and is an embodiment in which at least the upper surface of the air pine 1 to the main body has a double structure. That is, the air mat main body 21 in this case is composed of double skins 22 and 23 whose upper surfaces are spaced apart at an appropriate distance, and each skin 22 and 23 has a large number of ventilation holes 22a and 23, respectively.
a is formed. In this case, the vent holes 22a in the two skins 22,23.

The formation positions of 23a are set at different positions.

In this embodiment, the resistance of the air flowing upward from the air pine 1 to the main body 21 increases, so the amount of air supplied can be saved.

As explained above, the air mat device for a clinical examination bed according to the present invention can provide a comfortable cushion using air pressure, and also use the air ejected from the ventilation holes to Sensible temperature of a patient lying down,
Since humidity can be maintained in good condition, MRI
It is useful not only as an air pine mill device but also as an air pine mill device for various medical devices.

Although one embodiment has been described above, the present invention is not limited thereto, and can be modified and implemented in various ways within the scope of the gist. For example, the shape and structure of the air pine body, the materials used, the opening shape and distribution of the ventilation holes, the configuration of the air conditioner, the number of connected air pipes, etc. are arbitrary within the scope of the purpose of the present invention. can be determined.

[Effects of the Invention] As described above, when claim 1 of the present invention is used, it is possible to realize a new air pine mill device for a clinical examination bed that can be comfortably used even under the special conditions of use of medical diagnosis. When using claim 2, it is possible to provide a novel air mat 1 to main body that saves 1q in the amount of air supplied to the air mat main body.
