Description

[Detailed Description of the Invention] "Industrial application field" The present invention relates to a pack warmer for heating a pack warm compress for wet heat treatment.

"Prior art" Conventionally, pack warm compresses (hereinafter simply referred to as packs) in which a highly hygroscopic material such as bentonite is closed and sewn in a cloth bag,
Wet and absorb water by immersing it in a heating tank heated to about 80 ° C for a certain period of time, take it out, wrap it in a towel and apply it to the affected area for a certain period of time during treatment to relieve pain in the affected area. The law is known.

Then, a pack warmer used for heating and absorbing such a pack is provided (see FIGS. 2 and 3).

When the pack P is heated and absorbed by using the pack warmer, the pack P is set in the heating tank 1 and water is poured into the heating tank 1 to such an extent that the pack P is immersed therein. In this state, the heater 2 arranged under the heating tank 1 is energized, and the pack P
Is heated via warm water. At this time, moisture absorption is also performed at the same time. At the time of heating, the heater 2 is on / off controlled by a temperature sensor 3 provided in the heating tank 1 and a controller 4 composed of a thermostat, and the hot water in the heating tank 1 reaches a set temperature (for example, about 80 ° C.). To be kept.

A float switch 5 is provided in the heating tank 1,
For the purpose of preventing emptying, the heater 2 is not turned on unless the water level is above a certain level. Further, a basket 6 for receiving the pack P is provided in the heating tank 1 so that the pack P does not come into direct contact with the heater 2. Reference numeral 7 indicates a case cover, and 8 indicates a cover with a cover.

In this way, the pack P is heated and absorbed, but when the pack P reaches about 80 ° C, it is taken out, and 5 to 6 towels are overlaid on it and wrapped so that the outside surface is around 50 ° C. It is applied to the affected area for treatment. The pack P may be set in the heating tank 1 when the hot water in the heating tank 1 reaches about 80 ° C.

"Problems to be solved by the invention" In the conventional pack warmer described above, since relatively high temperature hot water gathers in the upper part of the heating tank 1 due to the difference in specific gravity, the upper part of the tank is high temperature and the lower part is low temperature. The temperature difference between the upper end side and the lower end side of the pack P that is stored vertically in the tank also occurs.

Further, among the plurality of packs P to be stored, the pack P located right above the heater 2 tends to have a relatively high temperature, and the packs P located on both sides of the tank 1 tend to have a low temperature. There is a temperature difference. Further, the surface of the pack P directly above the heater may be exposed to high temperature and damaged.

Further, when the pack P is fully loaded in the car 6 and heated, convection is less likely to occur and the heating efficiency is deteriorated.

An object of the present invention is to provide a pack warmer that can solve the above problems.

[Means for Solving the Problem] In order to achieve the above object, the present invention provides a heating tank (1) for storing a warm compress material (P) such as a pack for moist heat treatment in a liquid-immersed state, A pack provided with a heater (2) arranged in the heating tank for heating the hot compress material via a liquid, and a controller (4) for controlling the heater according to the temperature of the liquid in the heating tank. In the warmer, a circulation pipe (13) for circulating the liquid in the heating tank is provided in association with the heating tank, and the suction side of the circulation pipe is below the heating tank and the discharge side is the heating tank. A circulation pump (14) is installed in the circulation line so as to be located at the upper part of each, and a heater (2) is attached to the pump discharge side of the circulation line, and drainage is provided to the discharge side of the pump of the circulation line. Connect the pipe (20) to the branch and cut the liquid discharged from the pump at the branch to either the heating tank side or the drain pipe side. A switching valve (21) for replacement is provided.

[Operation] In the present invention, since the liquid in the heating tank is forcedly circulated by the pump, the temperature of the liquid in the heating tank becomes almost uniform, and it is difficult to make a temperature difference between a plurality of packs. Even in the pack, it is difficult to make a temperature difference between each part. Further, since the heat applied by the heater is evenly distributed to the corners of the tank, efficient heating can be performed.

In addition, since a heater is installed in the circulation line and the liquid heated by the heater is constantly flowing, the temperature around the heater does not become abnormally high, and the pack near the heater that has been seen in the past is heated above the set temperature. Eliminates the problem that the cloth is heated and gets damaged.

Further, as compared with the case where the heater is provided in the heating tank, the heater does not hinder the flow of hot water in the heating tank, and the temperature in the heating tank can be made uniform also from this point.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. The same components as those described in the conventional example are designated by the same reference numerals to simplify the description. FIG. 1 shows an embodiment of this invention. As shown in the figure, in this embodiment, a circulation pipe line 13 is provided so as to connect the suction port 11 at the lower part of the heating tank and the discharge port 12 at the upper part of the heating tank. I am wearing. In this way, the suction port 11 is provided in the lower part of the tank 1 and the discharge port 12 is provided in the upper part, so that the warm water of a relatively low temperature in the heating tank can be quickly sucked in without affecting the pack P, and This is to form a series of flows in which the liquid is discharged from the discharge port 12 and passes between the packs P to reach the lower part of the tank 1. Although one suction port 11 and one discharge port 12 are provided in the figure, a plurality of these may be provided. In addition, it is preferable to use a plurality of them in terms of making the temperature in the heating tank 1 uniform.

The pump 14 is supported by a support base 15 mounted on the case 7. This is because the pump 14 has a certain weight and is accompanied by vibration, so that no extra force is applied to the wall of the heating tank 1. The circulation pump 14 may be electrically connected to the controller 4 and may be operated only when the heater 2 heats it.

The heater 2 for warming the pack is provided on the pump discharge side of the circulation line 13. That is, the heater 2 is formed in an elongated shape so that it can be inserted and set in the conduit, and the heater 2 is inserted and set in one side of the bent portion of the circulation conduit 13 on the pump discharge side.

A drain hose 20 is branched and connected to the pump discharge side of the circulation line 13 with its lower end projected to the outside, and a flow from the circulation pump 14 is heated by a switching valve 21 provided at the branch portion. It can be arbitrarily switched to the tank 1 side or the drain hose 20 side.

Note that the forced drainage by the pump 14 has a limit due to the position (height) of the suction port 11, and here the natural drainage by the drain 15 is also used.

The switching valve 21 has a valve rod 21 so that it can be operated from the outside.
a extends to the outside of the case 7, and the lever 21b is attached to the tip thereof.
Is attached.

According to the pack warmer having the above structure, the circulation pump 14 forcibly circulates the warm water in the heating tank 1, so that the temperature of the warm water in the tank can be made more uniform than in the conventional one.
Therefore, the temperature control by the temperature sensor 3 and the thermostat can be performed with high accuracy.

Therefore, a temperature difference is less likely to occur between each of the plurality of packs P and between the individual packs P, and uniform heating can be performed.

In addition, since the warm water heated by the heater 2 constantly flows in one place during heating, the temperature around the heater 2 becomes abnormally high as seen in the conventional pack warmer. The inconvenience of damaging the outer surface of the pack P is eliminated.

Further, by switching the switching valve 21, the pump 14
The advantage is that forced drainage can be performed by using, and drainage can be performed in a short time.

The liquid to be placed in the heating tank 1 is not limited to water,
It may be another type of liquid having a large heat capacity.

[Advantage of Device] As described above, according to the present invention, since the liquid in the heating tank is forcedly circulated by the pump, the temperature of the liquid in the heating tank becomes almost uniform, and the temperature between the packs is increased. It is difficult to make a difference, and it is difficult to make a temperature difference between each part even in one pack. Further, since the heat applied by the heater is evenly distributed to the corners of the tank, heating can be performed with high thermal efficiency.

In addition, since a heater is provided in the circulation line and the liquid heated by the heater is constantly flowing, the temperature around the heater does not become abnormally high, and the pack near the heater, which has been seen in the past, exceeds the set temperature. Eliminates the problem that the cloth is heated and gets damaged.

Further, as compared with the case where the heater is provided in the heating tank, the heater does not obstruct the flow of hot water in the heating tank, and the temperature in the heating tank can be made uniform also from this point.

In addition, since the heater of the circulation line is provided on the discharge side of the pump, there is less risk of abnormal heating of the heater and burnout. By the way, if the heater is installed on the suction side of the pump, the pressure in the suction side pipeline becomes negative when the suction side pipeline is clogged with dust, etc. Is likely to occur, and as a result, the heater may be overheated and burned.

Furthermore, since the suction side of the pump is located in the lower part of the heating tank and the discharge side is located in the upper part of the heating tank, it is possible to suck and heat the warm water in the lower part of the heating tank, which has a relatively low temperature, It is effective in terms of thermal efficiency and uniformization of temperature in the tank.

Further, since the drain pipe is branched and connected to the pump discharge side, forced drainage can be performed through the pump, and the drainage can be performed in a short time.
