Description

  The present invention relates to a medical Peltier partial cooling device that can cool an affected part such as an ear at a required temperature.

  In recent years, in the medical field, when a cooling agent is applied to the occipital region and the temporal region located on the back (back) of the ear, the heat is cooled down to the skull, and the temperature of the inner ear cochlea is lowered by 1 to 2 ° C. from the normal temperature. It has been clarified that therapeutic effects are manifested in sexual hearing loss and unexplained diseases.

  However, in order to cool the temporal region located on the back of the ear, it is only possible to apply ice or other coolant. Therefore, it is suggested that a Peltier element should be used as a device for that purpose.

  As a conventional cooling device using a Peltier element, there is an example of the one disclosed in Japanese Patent Publication No. 10-246531 (thermoelectric conversion device). This is intended to efficiently cool the heat radiating portion of the Peltier element by devising the shape of the jacket through which the heat transfer medium passes.

  However, the relationship between the heat transfer medium passed through this thermoelectric converter and the surface temperature of the Peltier element is unclear, and it is doubtful whether an appropriate inner ear cooling effect will be obtained even if this is applied directly to the back of the ear. Therefore, it cannot be used as it is for medical use requiring accuracy, and must be designed separately.

  Japanese Patent Laid-Open No. 2000-99202 (pain relieving device and probe used therein) is provided with a rhythm mode in which heating and cooling are alternately repeated in order to relieve pain when the needle is stuck. is there.

However, this probe is only for pain relief and can be repeatedly heated and cooled, but cannot be used to cool the back of the ear and treat the ear. In addition, since cooling and heating are performed only by energization of the Peltier element, the degree thereof is also limited by the size of the Peltier element and cannot be used for ear treatment.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a cross-sectional view showing the overall configuration of a double Peltier partial cooling device of the present invention. FIG. 2 is an enlarged front view of the partial cooling probe of FIG. 3 is a cross-sectional view taken along line F3-F3 in FIG. FIG. 4 is a block diagram illustrating an example of a control device. 5 to 14 are explanatory diagrams showing a configuration example of the probe and a usage pattern thereof.

  As shown in FIGS. 1 to 4, the medical Peltier partial cooling device 1 according to one embodiment of the present invention includes a cooling water tank 3 that is cooled to a predetermined cooling water temperature T <b> 1 by a Peltier element 2. A cooling water tank device 4, a reciprocating circulation pipes 5 and 6 for sucking and returning the water in the cooling water tank 3, and a partial cooling probe 7 disposed in the middle of the circulation pipes 5 and 6 are provided. The partial cooling probe 7 is connected to the circulation pipes 5 and 6 at both ends, and the probe inner tank 8 is open to the probe inner tank 8 at one end surface thereof. And a probe-side Peltier element 9 provided with a heat radiating part 9a cooled by the sucked cooling water and a heat absorbing part 9b in contact with the affected part through a heat transfer sheet as appropriate on the back surface thereof, and the cooling water temperature T1 And the probe side pel By controlling the energization amount of the E elements 9, characterized by comprising a control unit 10 for controlling the medical temperature T2 corresponding to the temperature of the desired medical absorbing portion 9b of the probe side Peltier device 9.

  The cooling water tank device 4 has a frame material 12 supported by a foot 11, and a cooling water tank 3 made of copper or aluminum having a capacity of about 1 to 5 liters in a heat insulating material 13 supported by the frame material 12. And a unit of a plurality of Peltier elements 2 constituted by Peltier elements 2 is arranged at the bottom of the cooling water tank 3.

  A heat dissipating unit 14 is disposed below the Peltier element 2, and a cooling fan 15 that discharges airflow toward the opening is provided below the heat dissipating unit 14. Accordingly, the water in the cooling water tank 3 can be cooled by the Peltier element 2, and the amount of heat absorbed by the Peltier element 2 can be released downward through the heat dissipation unit 14 and the cooling fan 15.

  A control unit 10 and an AC power source connection port 16 are disposed on the side surface of the heat insulating material 13. In the battery-driven example, a battery (not shown) is disposed at this position. Battery sharing is also possible. This will be described in detail with reference to FIG.

  Further, a small circulation pump 17 is arranged in the cooling water tank 3 so that the sucked cooling water is sent to the partial cooling probe 7 through the flexible circulation pipe 5 made of a heat insulating hose. Although one probe 7 is shown in the figure, two or more probes 7 can be arranged in parallel through appropriate valves (not shown). The flow of the cooling water is indicated by directions (in) and (out). The circulation pipes 5 and 6 are flexible and have a small diameter (3 to 6 mm). Around the probe 7, the circulation pipe may be bundled in one direction.

  In addition, a large number of temperature sensors 18T are provided above and below the cooling water tank 3 and in each probe, and are connected to the control unit via a sensor wire 19, and a direct current is supplied to the probe-side Peltier element 9. A heating wire for supplying is wired. 1 to 3, many of these sensor wires and electric wires are omitted. Since there are many temperature sensors, they are shown as a cooling water tank side 18T and a probe side 18P. Similarly, the sensor wires are indicated by 19T and 19P.

  As shown in FIGS. 2 and 3, the partial cooling water probe 7 has a substrate 40 as a main body portion, and the circulation pipes 5, 6 and the probe internal tank 8 are connected via joints 20, 21. Yes. The Peltier element 9 opens the heat dissipating part 9a to the tank side, the back surface thereof is used as the surface heat absorbing part 9b, and a heat transfer seat cushion 22 is stretched here to cool the affected part on the surface. The sensor line 19P and the Peltier power line 23P are collected by a connector 24C and connected to the main coil of the control unit 10. Each partial cooling probe 7 is provided with a hand switch 24 (shown in FIG. 1) capable of adjusting the temperature.

  With the above configuration, the cooling water temperature T1 can be determined with respect to the medical target temperature T2 and supplied to the in-probe tank 8 of the partial cooling probe 7 via the circulation pipe 5. For example, it is assumed that a doctor designates 12 ° C. in ear treatment. Then, the surface temperature of the Peltier element 9 can be controlled to the target temperature T2 by setting the cooling water temperature to 13 ° C. that is slightly higher than that and energizing the probe side Peltier element 9. The control temperature can be changed for each probe 7 by the hand switch 24. Only one of them can be operated including valve operation. Furthermore, it is possible to make the temperature higher than the cooling water temperature T1 in advance by reversing the direction of the energizing current to the Peltier element 9. Since it is a double Peltier type, the cooling water temperature can be freely adjusted with a portable configuration, and the medical purpose temperature can be accurately maintained based on the temperature. In order to prevent water from coming into direct contact with the heat dissipating part 9a, a copper plate 9c is laid, and thermal grease or a sheet is sandwiched therebetween.

  Compared with providing a Peltier element only on the probe side, the cooling water temperature can be set freely, so that various control difficulties of the flowing water amount and the heat quantity acquisition effect can be eliminated, and the control can be performed easily, accurately and stably. By the way, when the cooling water is tap water, it cannot be used in places where there is no tap water, and it is inevitable that the drainage of the water cannot be saved, but if the tap water is 20 ° C, then it will drop by 8 ° C. It is difficult to obtain a medical target temperature, for example, 12 ° C. stably. The double Peltier type of the present invention can easily cope with these conditions and can be used accurately and stably. Moreover, even if the doctor's designated temperature is 10 ° C. or lower, 20 ° C. or higher, or even when these are variously changed, it can be easily handled.

The capacity / polarity controller 28 is connected to the cooling water tank side Peltier element 2. Therefore, based on the temperature input of each of the temperature sensors 18T-1 to 18T-7, the temperature of the cooling water tank 3 is appropriately maintained, and the circulating pump 17 is driven to supply the cooling water with an appropriate flow rate to the probe 7. be able to.

  As shown in the lower part of FIG. 4, an AC-DC power supply circuit 30 and a DC-DC power supply circuit 31 are connected to the control unit 10.

A capacity / polarity controller 34 is connected. The temperature sensors 18P-1 and 18P-2 change positions and detect the temperature of the element. The temperature sensor 18P-3 detects the probe surface temperature. The temperature sensor 18P-4 detects the temperature of the circulating water. The temperature sensor 18P-5 detects condensation. The infrared temperature sensors 18P-6 and 18P-7 detect the eardrum temperature in a non-contact manner using the amplifier of the IR element driving / operational amplifier 35. Therefore, the temperature on the probe 7 side can be detected, and the output temperature of the Peltier element 9 can be appropriately controlled. In order to obtain high accuracy, the temperature of both is appropriately controlled so as not to have a too large difference from the cooling water temperature T1.

Further, the control unit 10 includes an LCD driver 36a connected to the LCD display 36b, a main microcomputer 10 for storing a program for performing a control command, an E ² PROM 36c for storing each experimental value and an actual measurement value, and a keypad 37. Is connected. Parameter values can be input from the keypad 37 as appropriate. A temperature volume can be attached to the keypad 37. Therefore, by inputting a control basic program to the main microcomputer 10 and giving a temperature command on the keypad 37, the coolant temperature T1 and the temperature of the Peltier element 9 on the probe 7 side can be controlled appropriately, and the temperature of the Peltier element 9 can be The medical target temperature T2 can be stably controlled with high accuracy. Of course, when there are a plurality of probes 7, they can be individually controlled. Also, if each probe has an individual temperature volume, it can be arbitrarily adjusted including the patient's wishes individually.
