Detailed Description of the Invention <Industrial Application Field> The present invention enables water pillows, ice packs, and warm water bags to be brought into contact with desired parts of the body through which cold or hot water at a constant temperature is circulated. This invention relates to a medical cooling/warming device that functions as a compress.

<Conventional technology> Conventionally, water pillows, ice packs, etc. have been used to cool the affected area when fever occurs due to illness, burns, sunstroke, etc., and warm compresses and ice packs have been used to warm the affected area to relieve muscle pain, stiff shoulders, etc. Pastes (pastes) are each contained within a membrane, but in recent years, instead of these, for example, two agents sealed in a sheet-like bag are mixed at the time of use, and these two agents have a chemical cooling effect or So-called disposable simple cooling and heating devices, which generate heat and use a sheet-like bag to cool or warm the affected area, have come into widespread use.

In addition, the cooling device consists of a bag filled with a heat storage chemical agent, and by cooling this bag in a refrigerator, extremely low temperature cooling function can be obtained for a long time. Some can be used.

<Problems to be Solved by the Invention> However, the former disposable simple cooling device and heating device are limited to momentary use for several hours and are suitable only for use in emergencies. In addition, the emitting temperature or heat absorption power of these thighs changes over time and is not constant, and it is not possible to limit the temperature to the desired temperature, so it is difficult to effectively cool or heat the affected area depending on the symptoms. I can't.

On the other hand, with the latter reusable cooling device, the use is still limited to several hours, the generated temperature is not constant, and it is not possible to limit the temperature to a desired temperature. Furthermore, this method requires several hours of cooling time before use, making it unsuitable for emergency use.

Furthermore, as mentioned above, these cooling devices and heating devices can only be used for a few hours, so if they are used for a large number of patients in a hospital, for example, they must be used every few hours. need to be replaced for each patient, which is troublesome to manage, and may even lead to inability to provide appropriate treatment.

Therefore, in view of the above-mentioned conventional circumstances, the present invention can be used continuously, and the generated temperature can be kept constant and at a desired temperature, and the affected area can be effectively cooled according to the symptoms. The purpose of the present invention is to provide a medical cooling/warming device that can heat the body.

<Means for Solving the Problems> Therefore, the present invention provides a tank that stores cold water or hot water inside, a circulation passage that circulates the cold water or hot water in the tank, and a circulation passage that is interposed in the circulation passage. a pump, at least one medical heat exchange bag through which cold water or hot water is guided in the middle of the circulation passage, and an adjusting means for adjusting the amount of cold water or hot water that is circulated and supplied to the bag; A medical cooling/warming device characterized by comprising:

Effects> In such a configuration, the cold water or hot water stored in the tank is circulated and supplied to the bag via the circulation passage by driving the circulation pump. The amount of cold water or hot water that is circulated and supplied to the bag is adjusted by a pump for adjusting the amount of circulation and by the adjustment means, thereby controlling the temperature of the bag.

(Example) Next, one embodiment of the present invention will be described based on the drawings.

In FIG.
3 is a circulation pipe serving as a circulation passage for circulating the cold water or hot water in the tank 1; 4 is a circulation pump interposed in the circulation pipe 3; Reference numeral 5 indicates a branch pipe as a plurality of branch passages that branch from the circulation pipe 3 and then converge on the circulation pipe 3; 6 indicates a medical heat absorption or heat dissipation bag that is interposed in each branch pipe 5; 7; is an adjustment valve as an adjustment means for adjusting the amount of cold water or hot water that is circulated and supplied to the cough bag body 6 for each bag body 6.

Here, as the heat exchanger 2, for example, an evaporator or compressor in a refrigeration cycle, an electric heater, a combustion device, or the like is used.

The circulation pump 4 is interposed in the circulation vibe 3A extending from the tank 1 to the branch pipe 5.

The regulating pulp 7 uses a throttle valve that also serves to open and close the branch pipe 5.

The heat absorbing or heat dissipating bag 6 is configured as shown in FIG. 2, for example.

That is, the bag 6 is formed into a sheet shape, and its internal flow path is defined into a meandering path by intersecting comb-like partitions 6a.

An inlet section 6A and an outlet section 6B for cold water or hot water are provided at the base end and the terminal end of this meandering passage, respectively. Further, one end of a flexible tube 8 is connected to each of the inlet portion 6A and the outlet portion 6B, and a connector 9 is connected to the other end of the tube 8. On the other hand, a detachable connector 10 is also connected to the connector 9 on the side of the bag 6 at the connecting end of the branch pipe 5 to the bag 6, so that the bag 6 can be connected to the branch pipe 5 in a watertight manner as required. It is designed to be able to be attached and detached.

When attaching or detaching the bag 6 to the branch pipe 5, close the adjustment valve 7 and apply the opening/closing pulp 11 to the end of the branch pipe 5 on the connector 10 side to which the outlet connector 9 of the bag 6 is connected. Interpose and close this.

On the other hand, when in use, the adjustment valve 7 and the opening/closing pulp 1 are
Open 1 and put it into circulation.

In this configuration, water supplied into the tank 1 is cooled or heated by the heat exchanger 2 and stored in the tank 1 as cold water or hot water at a constant temperature. This cold water or hot water is driven by the circulation pump 4 to reach each branch pipe 5 via the circulation pipe 3A, and is supplied into each bag 6 from the inlet portion 6A of each bag 6. This cold water or hot water is returned to the tank l from the outlet portion 6B of each bag body 6 via the circulation vibrator 3B.

As such circulation of cold water or hot water continues, each bag body 6 is exposed to diseases, burns, and sunstroke.

It is used as a cooling device to cool the affected area when a person has a fever, such as a fever, or as a heating device to warm the affected area to relieve pain such as muscle pain or stiff shoulders.

According to the medical oil cooling/warming device having such a configuration, continuous circulation of cold water or hot water allows continuous use at all times. In addition, cold water or hot water at a constant temperature can always be supplied to the bag body 6 without the generated temperature changing over time, and the flow rate to the entire bag body 6 can be adjusted by adjusting the circulation amount by the pump 4, and the adjustment valve 7 By adjusting the flow rate, the temperature of each bag 6 can be appropriately adjusted to a desired temperature, and treatment can be performed with cold water or hot water at an appropriate temperature depending on the patient's medical condition.

Furthermore, unlike conventional cooling devices, this device does not require several hours of cooling time before use, and if a certain amount of cold or hot water is always stored in the tank 1, it can be used immediately when needed. , and can easily handle emergencies.

This medical oil cooling/warming device is mainly used in hospitals, etc., but when used for a large number of patients, it is necessary to replace the cooling device and heating device every few hours for each patient. There is no need to administer it, the management is simple, and appropriate treatment can be performed.

When used in a hospital, the connector 10 of the five branch pipes described above should be installed near the bed of the patient's room, and the connector 9 of the bag 6 should be connected to this connector 10 as necessary. Good. This is convenient because it can be done by the patient himself. Further, the adjusting pulp 7° opening/closing pulp 11 is similarly placed near the bed.

Furthermore, according to the medical oil cooling/warming device having such a configuration, it is possible to arrange multiple bags 6, and by adding branch pipes 5 as necessary, the number of bags 6 used can be increased.

Alternatively, the cold water and hot water stored in the tank 1 may be switched and used as necessary. In this case, the tank 1 is equipped with two types of heat exchangers 2, one for cooling and one for heating.

In addition, in this embodiment, as described above, the tank 1 is equipped with the heat exchanger 2 to always store a constant amount of cold water or hot water, but the heat exchanger 2 is not an essential requirement in the present invention. .

That is, there is a method in which, for example, ice is placed inside the container, and in this case also cold water at a constant temperature can be obtained.

Further, in this embodiment, a plurality of branch pipes 5 are connected to the circulation pipe 3 and a bag body 6 is provided for each branch pipe 5, but the branch pipe 5 is not provided and a single bag body 6 is simply connected to the circulation pipe 3. A bag body 6 may be inserted therein, and it is suitable for use in general households.

Further, although the oil cooling/warming device of the present invention was devised for medical use, it may also be used for medical purposes, such as as a cooling device for sleeping.
