Modes for carrying out the present invention will be described in Examples.

As shown in FIG. 1(A), the body cooling device 1 of the first embodiment includes a device main body 10, a hose 15 extending from the device main body 10, a cooling member 30 connected to the tip of the hose 15, and a cooling member 30. A cooling member cover 50 for covering the cooling agent 70 and a cooling agent cover 60 for storing the cooling agent 70 are provided. A temperature sensor 40 is extended from the cooling member 30, and a pocket 62 for inserting and holding the temperature sensor 40 is provided in the cooling member cover 60 substantially at the center of the lower surface side. Hook-and-loop fasteners 53 and 63 are provided inside the openings of the cooling member cover 50 and the refrigerant cover 60, respectively.

A main body 10 houses a compressor 110 using R134a as a refrigerant, and has a handle 11 for carrying on the upper surface and a filter insertion frame 13 for mounting a filter 12 replaceably on the side surface. An operation panel 20 is provided on the upper surface of the main body 10 . On the other side of the device main body 10, there are provided a fan outlet, a connecting portion with a power source, a main power switch, and the like.

As shown in FIGS. 1(B) and 1(C), the corpse cooling apparatus 1 contains a sufficiently cooled cooling agent 70 in a cooling agent cover 60, and a temperature sensor 40 is inserted into a pocket 62 of the cooling agent cover 60. The corpse W is held with the pocket side down, placed on the upper surface of the abdomen of the corpse W, the cooling unit 30 is placed thereon, and the compressor 110 is operated. At this time, the cooling member 30 is covered with the cooling member cover 50 .

At this time, as shown in FIG. 1C, the hook-and-loop fastener 53 at the open end of the cooling member cover 50 is partially opened, the signal line 41 is pulled out therefrom, and the temperature sensor 40 is inserted into the pocket of the refrigerant cover 60. Store in 62.

As shown in FIG. 1(D), the hose 15 is heat-insulated by winding a urethane sheet 17 around the outer side of a multi-structure tube 16 having an outward coolant path 16a in the center and a coolant return path 16b consisting of honeycomb-shaped cylindrical holes around it. The outside is covered with a cylindrical protective cover 18 . The multi-structure tube 16 is connected to the cooling member 30 via a dedicated connector 36, as shown in FIG. 1(C).

A signal line 41 of the temperature sensor 40 is connected to the apparatus body 10 through the protective cover 18 while being held by the urethane sheet 17, as shown in FIGS. 1(C) and 1(D). As a result, the temperature measured by the temperature sensor 40 sandwiched between the corpse W and the cooling agent 70 is input through the signal line 41 to the device body 10 during operation.

As shown in FIGS. 2(A) and 2(B), the cooling member 30 consists of a metal plate 31 with a coolant circulation path 32 formed thereon, the upper surface of which is insulated with foamed polyurethane, and a plastic cover 34 placed thereon. Assembled with screws. The metal plate 31 is formed by joining two metal plates with the coolant circulation path 32 formed thereon by pressing so as to sandwich a copper pipe for coolant circulation.

A rectangular notch (not shown) is formed in the center of the tip of the metal plate 31, and as shown in FIG. It is closed with a lid body 33 having a hole for it. In this embodiment, the lower surfaces of the metal plate 31 and the lid 33 are painted.

At the center of the upper surface of the plastic cover 34, as shown in FIG. The signal line 41 of the temperature sensor 40 is routed to the hose 15 side through this tunnel portion 35, and as shown in FIG. It is wired along the inner side of the protective cover 18 to the device main body 10 .

As shown in FIGS. 3(A) and 3(B), the cold insulator cover 60 is a bag body 61 obtained by heat-sealing both sides of a folded non-woven fabric sheet and heat-sealing a pocket 62 made of non-woven fabric in the center of the lower surface side. is. As shown in FIG. 3C, the cooling agent 70 is formed by heat-sealing both sides of a double-folded plastic sheet and a predetermined position between both sides to form gel-filled portions 71 to 75 of five sections in the width direction, After each was filled with cold insulating gel, the openings were heat-sealed. As shown in FIG. 3D, the cold insulator 70 is inserted into the bag body 61 from the opening side of the cold insulator cover 60 and the opening side is closed with the hook-and-loop fastener 63 . At this time, the cold insulator 70 is pre-cooled to a predetermined temperature in a freezer or the like.

After the cooled refrigerant 70 is stored in the refrigerant cover 60, the temperature sensor 40 is stored in the pocket 62 as shown in FIG. 3(E). The tip of the temperature sensor 40 is housed in the pocket 62 in the middle of the central section 73 of the cooling agent 70, as shown in FIG. 3(F). Thus, when using the body cooling device 1 of the embodiment, the temperature sensor 40 is sandwiched between the body W and the center of the cooling agent 70 as shown in FIGS. temperature can be measured in this state.

Next, the control system and the like of the body cooling apparatus 1 of this embodiment will be described. As shown in FIG. 4A, the apparatus main body 10 is provided with a control circuit 100 that inputs signals from the operation panel 20 and the temperature sensor 40 and outputs signals to the operation panel 20 and the compressor 10. .

The operation panel 20 includes a power switch 21, a setting switch 22, temperature setting switches 23 and 24, and a monitor 25, as shown in FIG. 4(B). By pressing the power switch 21, a start command is output to the compressor 110 via the control circuit 100, and the compressor 110 starts operating. At this time, the monitor 25 displays the current set temperature T0. Temperature setting switches 23 and 24 are used to adjust the set temperature T0. When the switch 23 marked with "+" is pressed, the set temperature increases, and when the switch 24 marked with "-" is pressed, the set temperature decreases. Changes in the set temperature T0 by operating the temperature setting switches 23 and 24 are displayed on the monitor 25. FIG. When the desired temperature is displayed on the monitor 25, the setting switch 22 is pressed to determine the set temperature T0. In this embodiment, the default setting temperature T0 is set to +5° C., and the setting temperature T0 can be increased/decreased by 1° C. each time the temperature setting switches 23 and 24 are pressed.

When the setting switch 22 of the operation panel 20 is pressed, the control circuit 100 starts the temperature control process shown in FIG. 4(C). As a prerequisite for starting this temperature control process, the power switch 21 of the operation panel 20 must be pressed.

The control circuit 100 reads and stores the set temperature T0 (S110), and reads the sensor temperature T1 input from the temperature sensor 40 (S120). Then, T1 is compared with T0 to determine whether or not T1≤T0-2° C. (S130). If determined as "YES", a stop command is output to the compressor 110 (S140).

On the other hand, if the determination in S130 is "NO", S140 is skipped and it is determined whether or not T1≧T0+2° C. (S150). If determined as "YES", a drive command is output to compressor 110 (S160).

Next, the control circuit 100 determines whether or not the temperature setting T0 has been changed (S170). If the determination is "NO" in S170, the process returns to S120, and if the determination is "YES", the process returns to S110. If the determination in S150 is "NO", the process skips S160 and proceeds to S170. The reason why the determination of S170 is timely executed is that the user may change the set temperature according to changes in the environmental temperature after the start of operation.

The control circuit 100 continues executing the temperature control process described above until the power switch 21 of the operation panel 20 is pressed again to issue an off command.

Next, a plastic case filled with water was used as a corpse W, and a device was installed as shown in Figs. The experiment was conducted with the set temperature T0=5°C. The results of this experiment are shown in the graph of FIG. The horizontal axis of the graph is 90 minutes per scale.

Prior to the experiment, the cooling agent 70 that had been previously cooled to 0° C. in a freezer was used. Also, the experiment was conducted in a room at about 26°C. During the experiment, the gel center temperature (Tj), the water temperature (Tw) in the poly case, the environmental temperature (Ta), the compressor side temperature (Tc), etc. were measured.

At the start of the experiment, it can be seen that the surface temperature (Tp) of the poly case is once lowered by the cooling agent 70 which has cooled sufficiently. In this experiment, as a result of starting the operation of the device at time t1, the compressor side temperature (Tc) rose sharply, and in response, the gel core temperature (Tj) and the water temperature (Tw) in the plastic case started to descend. This is because it is determined that S130=NO and S150=YES immediately after the start of operation.

After that, the fact that the side surface temperature (Tc) of the compressor drops at time t2 indicates that the operation of the compressor has been stopped. This indicates that the determination is switched to S130=YES and S150=NO as if the gel center temperature (Tj) has sufficiently decreased. Thereafter, the compressor is driven at time t3, the compressor is stopped at time t4, the compressor is driven at time t5, the compressor is stopped at time t6, . Then, it can be seen that the water temperature (Tw) in the poly case saturates to 10° C. around time t7. It can also be seen that after time t5, the compressor is repeatedly driven and stopped within the range of 30 minutes to 45 minutes.

In this way, the water temperature (Tw) in the plastic case that resembles the corpse W drops to around 12°C from around the time when the compressor starts and stops in a certain pattern, and after a short time t7, it continues for a long time. It can also be confirmed that 10°C can be maintained at all times.

From the above experimental results, the following facts can be confirmed.
(b) A refrigerant that has been chilled to around 0°C in advance is stored in a refrigerant cover, a temperature sensor is installed so as to measure the surface temperature of the center of the refrigerant, and a refrigerant circulation type cooling member is placed on the refrigerant. is placed on the body, and the compressor is switched on and off so that the sensor temperature detected by the temperature sensor is within a predetermined range with respect to the set temperature. It can be maintained for a long time.
(b) In particular, the action and effect of (a) can be easily exhibited by setting the measurement position by the temperature sensor to a position between the dead body and the cooling agent.

In this embodiment, the temperature sensor is installed between the cold insulator and the body, but it is also possible to install the temperature sensor between the cold insulator and the cooling member.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can be embodied in various forms without departing from the scope of the invention.

It can be used to keep corpses cool.
