Description

  The present invention relates to a carbon dioxide treatment device.

  In the peripheral arteries responsible for the circulation of the limbs, if the blood flow deteriorates or the artery is clogged, the blood circulation deteriorates and a peripheral state called peripheral circulatory disorder may occur. Many of the causes are said to be arteriosclerosis, which has increased with the aging of the population. If the peripheral circulatory disorder (occlusive arteriosclerosis) is severe, necrosis will begin from the tip of the toe, etc., so the foot must be cut at a location such as the ankle or above the knee, and the necrotic part must be removed. Sometimes it doesn't happen. In many cases, bacteria enter the cut surface and start to rot, and the upper part must be cut.

  As a treatment for peripheral circulatory disorder, carbonated bath therapy has been said to be good. The carbonated bath is a treatment method in which the affected area is immersed in warm water containing carbon dioxide (hereinafter referred to as carbonated hot water) such as hot water in which carbonated spring or carbonate powder for bath is dissolved. By performing such a carbonate bath, carbon dioxide contained in carbonated warm water is absorbed from the skin, and blood vessels in the skin are opened to improve blood circulation. As a result, there is an effect that symptoms such as numbness in places such as limbs and bedsores with poor blood circulation are alleviated and healing is accelerated.

In carrying out such a carbonate bath therapy, for example, devices described in Patent Documents 1 and 2 below are known as devices used for obtaining carbonated hot water.
JP 2002-143867 A JP 2003-53169 A

  By the way, when performing the carbonated bath of the affected part necrotized by the peripheral circulation disorder (obstructive arteriosclerosis), first remove the sachets and gauze, perform the carbonated bath on it, then wipe off the moisture with clean gauze, It is necessary to take appropriate measures by disinfecting and covering the affected area with gauze and bandages.

  Therefore, unless the hospital or clinic has staff that can perform disinfection and other appropriate treatment as described above, carbonic acid bath therapy cannot be performed on the affected area. For example, carbonic acid bath therapy is easily performed at home. It was difficult.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a carbon dioxide treatment device that can easily obtain the same therapeutic effect as compared with the carbonate bath therapy.

The carbon dioxide treatment device of the present invention configured to achieve the above object is
A carbon dioxide source,
A space forming member capable of forming a space surrounding a treatment target site;
A flow path forming member that forms a flow path for sending carbon dioxide from the carbon dioxide source into the space.

Moreover, it is desirable that the carbon dioxide treatment device of the present invention further comprises the following configuration.
First, it is preferable that the space forming member has a structure having a gas discharge port that allows gas to escape from the space to the outside, and can be configured to close the gas discharge port during treatment.

The space forming member or the flow path forming member may be provided with exhaust means for sucking the gas in the space and discharging it to the outside.
The carbon dioxide source may be a carbon dioxide cylinder.

In addition, the supply amount of carbon dioxide from the carbon dioxide source may be controlled according to the pressure in the space.
Further, the supply amount of carbon dioxide from the carbon dioxide source may be controlled according to the carbon dioxide concentration in the space.

Moreover, it is good to provide the water vapor | steam supply means which can supply water vapor | steam into the said space.
Further, the space forming member is a bag having an opening for introducing the treatment target site into the space, and the periphery of the opening is formed by adhering the opening to the patient's body side or mutually. A closeable adhesive surface may be provided.

  Alternatively, the space forming member is a bag having an opening for introducing the treatment target site into the space, and a pair of male members capable of closing the opening by engaging with each other at the periphery of the opening. Also, a fastener made of a female member may be provided.

  In the carbon dioxide treatment device of the present invention configured as described above, a space surrounding the treatment target site is formed by the space forming member, and the carbon dioxide is passed through the flow path formed by the flow path forming member in that state. When carbon dioxide is sent from the source into the space, the space surrounding the treatment target area becomes extremely high in carbon dioxide concentration, and the treatment target area in this space is exposed to an atmosphere with high carbon dioxide concentration become.

  At this time, if the surface of the treatment target site is in a certain wet state, carbon dioxide dissolves in the water present on the surface of the treatment target site. Further, when the treatment target portion is in a relatively dry state, the treatment target portion may be moistened by some additional means. For example, an ointment containing moisture on the surface of the treatment target portion may be used. By applying together, such as applying water vapor so that the surface of the treatment target area is in a high humidity state that is moist, the treatment target area becomes moist, Carbon dioxide dissolves in the water present.

As a result, carbon dioxide (carbonic acid) dissolved in moisture present on the surface of the treatment target site is absorbed from the skin, and blood circulation at the treatment target site is improved.
If such a carbon dioxide treatment device is used, unlike carbonic acid bath therapy using hot carbonated water, treatment can be performed using carbon dioxide, which is a gas, so that it is not necessary to immerse the treatment target site in hot carbonated water. Therefore, when treating a necrotic affected area, it is not necessary to remove the sachet or gauze before the treatment, and treatment such as wiping or disinfecting water with the gauze after the treatment is unnecessary. Therefore, the treatment can be carried out more easily than the carbonate bath therapy, and for example, the treatment can be carried out easily even at home.

  In addition, when the space forming member has a structure having a gas discharge port that allows gas to escape from the space to the outside and is configured to be able to close the gas discharge port during treatment, the gas discharge port is first opened. By introducing carbon dioxide into the space, the air existing in the space is discharged from the gas discharge port, and by replacing the air in the space with carbon dioxide, a sufficient concentration of carbon dioxide can be obtained in a short time. It can be filled and treated.

  Further, when the space forming member or the flow path forming member is provided with an exhaust unit that sucks the gas in the space and discharges it to the outside, the air present in the space can be discharged using the exhaust unit. Therefore, also in this case, the treatment can be performed by filling the space with a sufficient concentration of carbon dioxide in a short time.

  Further, when the carbon dioxide source is a carbon dioxide cylinder, carbon dioxide can be supplied most simply. In addition to using a carbon dioxide cylinder, carbon dioxide can be obtained by various methods. For example, dry ice or carbonated water may be used as a carbon dioxide source. When supplying carbon dioxide generated in a container containing dry ice or carbonated water, a heating means for applying heat to the dry ice or carbonated water in the container may be provided. In this way, since the amount of carbon dioxide generated can be increased by the heat from the heating means, the carbon dioxide concentration can be increased in a shorter time than when the same kind of heating means is not provided. Further, a substance that generates carbon dioxide by a chemical reaction, for example, sodium bicarbonate and an acid may be reacted to generate carbon dioxide. Any acid can be used as the acid, but citric acid may be used as an acid that is highly safe, easy to handle, and inexpensive. Furthermore, carbon dioxide can also be obtained by electrolyzing water using a carbon electrode.

  Also, when the amount of carbon dioxide supplied from the carbon dioxide source is controlled according to the pressure in the space, the amount of carbon dioxide supplied to the space becomes excessive and the amount of carbon dioxide leaked wastefully. This is desirable because it does not increase or the amount of carbon dioxide supplied into the space becomes too small to reduce the therapeutic effect.

  In addition, when the amount of carbon dioxide supplied from the carbon dioxide source is controlled in accordance with the carbon dioxide concentration in the space, the amount of carbon dioxide supplied into the space becomes excessive, and carbon dioxide that leaks wastefully. This is desirable because the amount of carbon does not increase or the amount of carbon dioxide supplied into the space becomes too small and the therapeutic effect is not weakened.

  In addition, if a water vapor supply means capable of supplying water vapor into the space is provided, the surface of the treatment target portion becomes moist and carbon dioxide is easily dissolved in the water, so that the treatment effect by carbon dioxide can be enhanced. it can. Even when such a water vapor supply means is not provided, the surface of the treatment target site can be moistened by other methods. For example, an ointment containing moisture may be applied to the surface of the treatment target site.

  In addition, as long as the space forming member can form a space surrounding the affected area, the material and specific form thereof are arbitrary. However, the space forming member is relatively versatile, and is convenient for, for example, enveloping limbs. For example, the space forming member may be a bag having an opening for introducing the treatment target site into the space. In this case, if the bag is a disposable type, the damaged bag is not reused and is clean.

  Since such a bag has an opening for introducing the treatment target site into the space, it is necessary to close the opening during the treatment. Therefore, it is preferable to provide means for closing the opening. For example, a peripheral surface of the opening may be provided with an adhesive surface capable of closing the opening by adhering to the patient's body side or to each other. . Or the fastener which consists of a pair of male member and female member which can mutually engage and can close an opening may be provided in the peripheral part of the opening.

  As the flow path forming member, for example, a flexible tube can be used, and in this case, even when the space forming member is moved together with the treatment target portion, the tube is curved to some extent. The source of carbon dioxide is not moved. Therefore, the carbon dioxide supply source is not moved in an unexpected direction and causes trouble, and the affected part is not forced to stand still in order to prevent such trouble.

  Further, the flow path forming member is a tube having a lumen serving as the flow path, and the space forming member is a bag having a tube introduction port for introducing the tip of the tube into the space, The tube is inserted into the tube introduction port in a state where the tube can be pulled out from the tube introduction port, and the tube introduction port is provided with a sealing member that seals the tube introduction port when the tube is pulled out. It may be.

  By adopting such a configuration, after the tube is used for supplying carbon dioxide, it can be removed from the space forming member, so that the carbon dioxide supply source is not moved together with the space forming member. . In addition, when the tube is pulled out from the tube introduction port, the sealing member blocks the tube introduction port, so that carbon dioxide does not leak out from the tube introduction port.

  If the sealing member has a structure capable of preventing the leakage of carbon dioxide, the specific structure thereof is arbitrary. For example, for example, the sealing member is disposed inside the bag with the tube. It is good for it to be the structure which pinches | interposes the part which has passed through the pair of clamping part from the outer side of the said bag. In this case, the sealing member is configured such that the sandwiching portion is elastically deformable, and the sandwiching portion is elastically deformed when a portion where the tube is passed through the bag is sandwiched from the outside of the bag. Thus, the tube is allowed to pass through, and when the tube is pulled out, it is preferable that the elastically deformed portion of the clamping portion is restored to seal the tube introduction port.

  Furthermore, the space forming member is a bag that expands with the supply of carbon dioxide, and an expansion blocking member that prevents the space forming member from expanding further outward is provided outside the space forming member. It may be.

  If such a configuration is adopted, even when a large bag that is easy to put in and out of the treatment target portion is adopted as the space forming member, when filling the inside with carbon dioxide, when the space forming member swells to some extent, Since the expansion preventing member prevents the space forming member from expanding, it is not necessary to fill the space forming member with an excessive amount of carbon dioxide, and the amount of carbon dioxide used can be suppressed.

  As described above, according to the carbon dioxide treatment device of the present invention, the same therapeutic effect can be easily obtained as compared with the carbonate bath therapy using carbonated hot water.

  Next, embodiments of the present invention will be described with some examples.

  As shown in FIG. 1, the carbon dioxide treatment device described below is a space forming member capable of forming a space surrounding a carbon dioxide cylinder 1 that is a carbon dioxide source and a treatment target site (a foot in the present embodiment). And a tube 5 that is a flow path forming member that forms a flow path for sending carbon dioxide from the carbon dioxide cylinder 1 to the inside of the bag 3. A three-way valve 7 is provided in the middle of the tube 5, and a suction pump 9 that sucks the gas inside the bag 3 and discharges it to the outside is connected to the three-way valve 7. The opening of the bag 3 is provided with an adhesive tape 11 that can close the opening by adhering to the patient's body side or to each other.

  The bag 3 can be attached so that the opening is squeezed so as to be in close contact with the patient's body, and by sticking the adhesive tape 11 provided around the opening to the patient's body, gas leakage from the opening is suppressed. it can. The bag 3 is of a disposable type, and after use, the tube 5 is removed from the connector 13 and only the bag 3 is discarded.

  In order to perform treatment with the carbon dioxide treatment device configured as described above, first, the affected part (the affected part is a foot in the figure) is wrapped in the bag 3 and the opening is closed with the adhesive tape 11. When the affected area is relatively dry, the affected area is moistened by a method such as applying an ointment containing moisture to the affected area in advance.

  Subsequently, the three-way valve 7 is operated to connect the flow path connecting the bag 3 and the suction pump 9, and the suction pump 9 is operated to discharge the air inside the bag 3 to the outside. By this operation, when carbon dioxide is supplied in the subsequent operation, it is possible to prevent the carbon dioxide concentration from being lowered by the air initially in the bag 3.

  Subsequently, the three-way valve 7 is operated again so that the flow path connecting the carbon dioxide cylinder 1 and the bag 3 is communicated, and the valve 15 of the carbon dioxide cylinder 1 is operated so that the carbon dioxide cylinder 1 transfers the carbon dioxide into the bag 3. Send in carbon. Thereby, the inside of the bag 3 is in a state with a high carbon dioxide concentration, and the affected part is exposed to an atmosphere with a high carbon dioxide concentration. As a result, more carbon dioxide is absorbed from the skin and blood circulation in the affected area is improved.

  Note that part of the carbon dioxide inside the bag 3 is absorbed by the affected area, and another part leaks outside through the gap of the bag 3, so the carbon dioxide concentration inside the bag 3 is maintained at a certain level or more. In order to do this, by adjusting the opening of the valve 15 of the carbon dioxide cylinder 1, a small amount of carbon dioxide is always supplied to the bag 3, or the valve 15 of the carbon dioxide cylinder 1 at an appropriate timing. It is preferable to replenish carbon dioxide with the interior of the bag 3 irregularly by performing an opening / closing operation.

In order to confirm the therapeutic effect of the carbon dioxide treatment device as described above, the following treatment test was performed.
The subject is a 61-year-old male who is undergoing maintenance dialysis for diabetes (use of insulin) and diabetic nephropathy, has peripheral vascular circulatory failure due to diabetes, and complains of strong coldness in the lower limbs.

  Applying an ointment containing a moisturizing agent (hilloid) to both lower limbs of this test subject, covering the left lower limb with the bag 3 of the carbon dioxide treatment device, supplying carbon dioxide into the bag 3 in this state, Therefore, the right lower limb was covered with an air-filled bag, left as it was, and after 40 minutes, both lower limb bags were removed.

The subject recognized a warm sensation in the left lower limb several minutes after the start of carbon dioxide filling, and this warm sensation persisted for several hours after the bag 3 was removed.
In addition, hemodynamics before and after performing the above treatment were measured using a laser Doppler blood flow imaging device (manufactured by Moor Instruments, UK). This laser Doppler blood flow imaging device is a blood flow meter that scans laser light on a tissue and visualizes the hemodynamics of the microcirculation in color by analyzing the scattered light. The distribution can be imaged non-invasively. The hemodynamic measurement was performed before the start of the treatment, immediately after the completion of the treatment (40 minutes after the start of the treatment), 10 minutes after the completion of the treatment, and 20 minutes after the completion of the treatment.

  As a result of this measurement, it was confirmed that the blood flow was greatly improved in the left lower limb after the completion of the above treatment and before the start of the treatment. Further, the state of good blood circulation was maintained not only immediately after the completion of the treatment but also after 10 minutes and 20 minutes after the completion of the treatment. On the other hand, in the right lower limb, it was confirmed that the blood circulation was slightly better than before the start of the treatment, but the degree was slight compared to the left lower limb, and the difference was significant as the left lower limb. Was not recognized.

  In the carbon dioxide treatment apparatus as described above, unlike carbonic acid bath therapy using hot carbonated water, since carbon dioxide, which is a gas, is used, it is not necessary to immerse the affected part in hot carbonated water. Therefore, when treating a necrotic affected area, it is not necessary to remove the sachet or gauze before the treatment, and treatment such as wiping or disinfecting water with the gauze after the treatment is unnecessary. Therefore, the treatment can be carried out more easily than the carbonate bath therapy, and for example, the treatment can be carried out easily even at home.

  Further, in the case of the carbon dioxide treatment device of the present embodiment, the air inside the bag 3 can be discharged in advance using the suction pump 9 before sending the carbon dioxide from the carbon dioxide cylinder 1 to the bag 3. Therefore, the carbon dioxide concentration inside the bag 3 can be instantaneously increased as compared with the case where a mechanism for removing the air inside the bag 3 is not provided.

  In the following description, parts different from the above-described embodiment will be described in detail, and the same reference numerals as those used in the above-described embodiment will be attached to configurations that are not different from the above-described embodiment. Therefore, the detailed description is omitted.

  As shown in FIG. 2, the carbon dioxide treatment apparatus described below includes a carbon dioxide cylinder 1, a bag 3, and a tube 5 similar to those in the first embodiment. However, unlike the first embodiment, a three-way valve is provided. 7 and the suction pump 9 are not provided, and instead, the bag 3 as a space forming member has a structure having a gas discharge port 17 through which gas escapes from the inside to the outside. This gas discharge port 17 can be opened and closed arbitrarily by operating by hand.

  When the treatment is performed by the carbon dioxide treatment device configured as described above, the gas discharge port 17 is initially opened, and the valve 15 of the carbon dioxide cylinder 1 is operated in that state, so that the bag is removed from the carbon dioxide cylinder 1. Carbon dioxide is sent into the interior of 3. Thereby, the air inside the bag 3 is pushed out from the gas discharge port 17, and the inside of the bag 3 gradually becomes in a high carbon dioxide concentration state.

  Thereafter, the gas discharge port 17 is closed at an appropriate timing, and the gas discharge port 17 is kept closed during the subsequent treatment. In this state, carbon dioxide does not leak from the gas discharge port 17 and the inside of the bag 3 is in a high carbon dioxide concentration state, so that the affected part is exposed to an atmosphere with a high carbon dioxide concentration, and the affected part is exposed. Blood circulation is improved.

Even the carbon dioxide treatment device as described above has the same operation and effect as the device described in the first embodiment, so that the treatment can be carried out more easily than the carbonated bath therapy.
Further, in the case of the carbon dioxide treatment device of the present embodiment, since the air inside the bag 3 can be discharged from the gas discharge port 17 when the carbon dioxide is sent from the carbon dioxide cylinder 1 to the bag 3, such a gas discharge port. Compared to the case where no is provided, the carbon dioxide concentration inside the bag 3 can be instantaneously increased.

  As shown in FIG. 3, the carbon dioxide treatment device described below includes a carbon dioxide cylinder 1, a bag 3, a tube 5, and the like similar to those in the first and second embodiments. Unlike the first and second embodiments, the pressure sensor 21 that detects the internal pressure of the bag 3, the electric valve 23 that can increase or decrease the amount of carbon dioxide supplied from the carbon dioxide cylinder 1, and the pressure sensor 21 detect the pressure. A control device 25 is provided for controlling the internal pressure of the bag 3 to fall within a preset numerical range by opening and closing the electric valve 23 according to the internal pressure of the bag 3. Although omitted in FIG. 3 to show only the main part, the suction pump 9 and the gas discharge port 17 shown in the first and second embodiments may be provided also in this embodiment.

  When treatment is performed by the carbon dioxide treatment device configured as described above, when the pressure detected by the pressure sensor 21 is not sufficiently increased, the open / close level of the electric valve 23 is controlled by the control device 25, and As a result of the valve 23 being actuated to open, carbon dioxide is sent from the carbon dioxide cylinder 1 into the bag 3. Thereby, the inside of the bag 3 is gradually in a high carbon dioxide concentration state.

  After that, when the pressure detected by the pressure sensor 21 is sufficiently increased, the opening / closing level of the electric valve 23 is controlled by the control device 25 and the electric valve 23 is actuated in the closing direction. The amount of carbon dioxide supplied to the vehicle decreases or the supply stops. In this state, since the inside of the bag 3 is in a high carbon dioxide concentration state, the affected area is exposed to an atmosphere with a high carbon dioxide concentration, and blood circulation in the affected area is improved.

  Furthermore, when the internal pressure of the bag 3 decreases as a result of the carbon dioxide being absorbed by the affected part or leaking outside the bag 3 with the passage of time thereafter, the decrease in the internal pressure is detected by the pressure sensor 21 and controlled. The opening / closing level of the electric valve 23 is controlled by the device 25 and the electric valve 23 is operated in the opening direction. As a result, carbon dioxide is replenished from the carbon dioxide cylinder 1 into the bag 3. As a result of such replenishment being carried out continuously or intermittently, the internal pressure of the bag 3 is maintained so as to remain within a preset numerical range, and the inside of the bag 3 is maintained in a high carbon dioxide concentration state. It will be.

Even the carbon dioxide treatment device as described above has the same operation and effect as the devices described in the first and second embodiments, so that the treatment can be carried out more easily than the carbonate bath therapy.
Further, in the case of the carbon dioxide treatment device of the present embodiment, the amount of carbon dioxide supplied from the carbon dioxide cylinder 1 is controlled according to the internal pressure of the bag 3, so the amount of carbon dioxide supplied to the inside of the bag 3. However, the amount of carbon dioxide leaked unnecessarily increases, and the amount of carbon dioxide supplied into the space becomes too small, and the therapeutic effect is not weakened.

In the carbon dioxide treatment device shown as the third embodiment, even if a carbon dioxide concentration sensor 21 ′ is employed instead of the pressure sensor 21, the supply amount of carbon dioxide can be automatically controlled.
That is, in the apparatus configuration shown in FIG. 3, when the pressure sensor 21 is replaced with the carbon dioxide concentration sensor 21 ′, the control is performed when the carbon dioxide concentration detected by the carbon dioxide concentration sensor 21 ′ is not sufficiently increased. The opening / closing level of the electric valve 23 is controlled by the device 25 and the electric valve 23 is operated in the opening direction. As a result, carbon dioxide is sent from the carbon dioxide cylinder 1 into the bag 3. Thereby, the inside of the bag 3 is gradually in a high carbon dioxide concentration state.

  Thereafter, when the carbon dioxide concentration detected by the carbon dioxide concentration sensor 21 ′ is sufficiently increased, the open / close level of the electric valve 23 is controlled by the control device 25, and the electric valve 23 is operated in the closing direction. The amount of carbon dioxide supplied to the inside of the bag 3 decreases or the supply stops. In this state, since the inside of the bag 3 is in a high carbon dioxide concentration state, the affected area is exposed to an atmosphere with a high carbon dioxide concentration, and blood circulation in the affected area is improved.

  Furthermore, when the carbon dioxide is absorbed by the affected part or leaks to the outside of the bag 3 with the passage of time thereafter, and the carbon dioxide concentration inside the bag 3 decreases, the decrease in the carbon dioxide concentration The detection level is detected by the sensor 21 ′, and the opening / closing level of the electric valve 23 is controlled by the control device 25. As a result of the electric valve 23 operating in the opening direction, carbon dioxide is replenished from the carbon dioxide cylinder 1 into the bag 3. As a result of such replenishment being performed continuously or intermittently, the carbon dioxide concentration inside the bag 3 is maintained so as to remain within a preset numerical range, and the inside of the bag 3 is in a state where the carbon dioxide concentration is high. Will be maintained.

Even with the carbon dioxide treatment device as described above, the same effects and effects as those of the devices described in the first to third embodiments can be obtained, so that the treatment can be carried out more easily than the carbonate bath therapy.
Further, in the case of the carbon dioxide treatment device of the present embodiment, the supply amount of carbon dioxide from the carbon dioxide cylinder 1 is controlled according to the carbon dioxide concentration inside the bag 3, so that it is supplied into the bag 3. The amount of carbon dioxide is excessive, and the amount of carbon dioxide that leaks wastefully does not increase, or the amount of carbon dioxide supplied into the space becomes too small and the therapeutic effect is not weakened.

  As shown in FIG. 4, the carbon dioxide treatment device described below includes the same carbon dioxide cylinder 1, the bag 3, the tube 5, and the like as those of the first to fourth embodiments, and also supplies water vapor into the bag 3. The humidifier 27 which is a water vapor supply means which can be supplied is provided. The humidifier 27 is connected to the connector 31 of the bag 3 via the hose 29 and can feed the water vapor generated by the humidifier 27 into the bag 3.

  Even in the carbon dioxide treatment device as described above, the operation and effect equivalent to those of the devices described in the first to fourth embodiments can be obtained by feeding carbon dioxide into the bag 3, so that it is easier than the carbonate bath therapy. Can be treated.

  Further, in the case of the carbon dioxide treatment device of the present embodiment, water vapor can be sent into the bag 3 simultaneously with carbon dioxide, so that the surface of the affected area is easily moistened and carbon dioxide is easily dissolved in the moisture. , The therapeutic effect of carbon dioxide can be enhanced.

What was shown to Fig.5 (a) and the same figure (b) is the bag 33 which can be utilized in the carbon dioxide treatment apparatus of Examples 1-5 mentioned above.
The bag 33 is provided with the adhesive tape 11 for closing the opening as in the case of the bag 3 described in the first to fifth embodiments. However, in order to narrow down the middle of the bag 33, the adhesive tapes 35 and 37 are provided. I have. As shown in FIG. 5B, these adhesive tapes 35 and 37 are wound around the bag 33 so as to squeeze the bag 33 after the affected part is put in the bag 33. The substantial volume of can be reduced.

  If such a bag 33 is used, since the bag 33 can be designed to be large so that the bag 33 can be slowly attached to the affected part, workability when attaching to the affected part is higher than that of a small bag. Become. Moreover, since the volume can be reduced by squeezing the bag 33 after being attached to the affected part, carbon dioxide can be filled in the bag 33 without sending an excessive amount of carbon dioxide.

FIG. 6A to FIG. 6D are diagrams showing the vicinity of the opening of the bag 41 that can be used in the carbon dioxide treatment devices of Examples 1 to 5 described above.
The bags 3 and 33 described above are provided with the adhesive tape 11 as a means for closing the opening. However, the bag 41 according to the present embodiment is a fastener instead of the adhesive tape 11 as a means for closing the opening. 43.

The fastener 43 includes a pair of male members 45 and female members 47 that can be engaged with each other to close the opening of the bag 41 (see FIG. 6B), and can be arbitrarily opened and closed any number of times.
If such a bag 41 is used, as shown in FIG. 6C, when a part of the opening is brought into close contact with the periphery of the part through the opening, the fastener 43 is used for the remaining part. Therefore, the opening of the bag 41 can be closed very easily. In addition, as shown in FIG.6 (d), if the opening part is pinched | interposed with the fastener 49, it can prevent more reliably that the opening closed by the fastener 43 will open.

  As shown in FIG. 7, the carbon dioxide treatment device described below includes a bottle 51 containing carbonated water, a stopper 53 that can be attached to the mouth of the bottle 51, a bag 55 that can form a space surrounding the affected area, The tube 57 which comprises the flow path which guides the carbon dioxide generated in the bottle 51 into the bag 55, and the warmer 59 which heats the circumference | surroundings of the bottle 51 are provided.

  The bottle 51 is a commercially available bottled carbonated water bottle whose mouth is closed by a screw cap. The stopper 53 has a threaded portion having the same shape and dimensions as the screw cap, and can be attached to the mouth of the bottle 51. The bag 55 can be attached so that the opening is narrowed and the patient's body is almost in close contact. In the middle of the tube 57, a trap 61 is provided to allow gas to pass but not liquid. The heater 59 has a built-in heating wire, and can warm the temperature of the container accommodated inside to about 30 degrees.

  In order to perform treatment with the carbon dioxide treatment device configured as described above, a stopper 53 is attached to a commercially available carbonated water bottle 51, the affected part (the affected part in the figure is a foot) is wrapped in a bag 55, and the bottle 51 is added. Heated by the warmer 59, carbon dioxide generated from the carbonated water in the bottle 51 is sent into the bag 55. Thereby, the inside of the bag 55 is in a high carbon dioxide concentration state, and the affected part is exposed to an atmosphere with a high carbon dioxide concentration. As a result, carbon dioxide is absorbed from the skin and blood circulation in the affected area is improved. Even with such a carbon dioxide treatment device, the same effects and effects as those of the device described in the first embodiment can be obtained, so that the treatment can be carried out more easily than the carbonate bath therapy.

In addition, since heating is performed by the heater 59 to promote generation of carbon dioxide, the concentration of carbon dioxide can be increased in a shorter time than when the same kind of heating means is not provided.
In addition, since the trap 61 is provided between both ends of the tube 57, even when the bottle 51 falls down, carbonated water does not flow into the bag 55, and even if water vapor is condensed in the tube 57, The water does not flow into the bag 55.

  The carbon dioxide treatment apparatus described below includes a bag 71, a cover 72, tubes 73, 75, and 77, a T joint 79, tube clamps 81 and 83, a pinch 85, and the like as shown in FIG. .

The bag 71 is a space forming member capable of forming a space surrounding a treatment target site (in the case of the present embodiment, a foot), and has a sufficient size that allows the patient's foot to be taken in and out.
The cover 72 is mounted so as to be wound around the outside of the bag 71. As shown in FIG. 8B, the stretchable cloth 87, the female surface fastener 88 having innumerable loop members, and innumerable And a male fastener 89 having a hook member.

  In the case of the present embodiment, since a foot is assumed as a treatment target portion, the cloth 87 is cut into a shape suitable for being wound around the foot. Specifically, the lower leg is wrapped around the lower leg. It is cut into a shape having a portion 87a, a middle foot surrounding portion 87b wound around the middle foot portion, and a connecting portion 87c for connecting the lower leg surrounding portion 87a and the middle foot surrounding portion 87b.

  The female fasteners 88 are belt-shaped, and two are provided on the lower leg surrounding portion 87 a and one on the middle foot surrounding portion 87 b, and each is sewn to the cloth 87. The male surface fastener 89 is a small piece having a length shorter than that of the female surface fastener 88, two at the lower leg surrounding portion 87a and one at the middle foot surrounding portion 87b, respectively, at positions corresponding to the female surface fastener 88. Is provided. The female surface fastener 88 and the male surface fastener 89 are provided on the front side of the cloth 87 and on the back side of the cloth 87 so that the cloth 87 engages with each other when the cloth 87 is wound around the foot. It has become.

  As shown in FIG. 8 (a), the cover 72 configured in this manner is configured such that the lower leg encircling part 87a is wrapped around the lower leg part with the buttocks between the two connecting parts 87c. The foot encircling portion 87b is wound around the middle foot portion, and the female surface fastener 88 and the male surface fastener 89 are engaged with each other to be attached to the outside of the bag 71. At this time, the female surface fastener 88 and the male surface fastener 89 at the position near the knee of the lower leg surrounding portion 87a are engaged with each other by narrowing the opening of the bag 71 so as to be in close contact with the lower limb portion. The carbon dioxide can be prevented from leaking from the opening. Further, the other female surface fastener 88 and the male surface fastener 89 are engaged in a relatively loosely wound state, but wound so as to have an outer peripheral dimension smaller than the outer peripheral dimension of the bag 71, The bag 71 which inflates with the supply of carbon dioxide is prevented from inflating excessively. That is, the cover 72 corresponds to the expansion preventing member referred to in the present invention.

  When such a cover 72 is employed, even when a large bag 71 that allows easy entry / extraction of a treatment target portion is employed, when the bag 71 is inflated to some extent when the inside is filled with carbon dioxide, Since the cover 72 prevents swelling, it is not necessary to fill the bag 71 with an excessive amount of carbon dioxide, and the amount of carbon dioxide used can be suppressed.

  The tubes 73 and 75 and the T joint 79 are flow path forming members that form a flow path for sending carbon dioxide from the carbon dioxide source to the inside of the bag 71. Further, a tube 77 is connected to the T joint 79, and a flow path for sucking the gas inside the bag 71 from the tube 77 side and discharging it to the outside is formed.

  The tube clamps 81 and 83 are members that close the lumens of the tubes 73 and 77 by pressing the tubes 73 and 77 from the side surfaces. These tube clamps 81 and 83 are normally operated to the side that closes the lumens of the tubes 73 and 77, and only the tube clamp 81 moves to the side that opens the lumen of the tube 73 when supplying carbon dioxide. Operated. Further, only the tube clamp 83 is operated to open the lumen of the tube 77 when the gas inside the bag 71 is discharged to the outside.

  As shown in FIG. 9A, the pinch 85 has a pair of clamping portions 91, 91, and these clamping portions 91, 91 are always in close contact with the urging force of the spring 93, while the urging force of the spring 93 is When the operation unit 94 is operated against the operation, the gap between the holding units 91 and 91 is opened. The sandwiching portions 91 and 91 are formed of rubber sponges that are elastically deformed only by applying a slight external force.

  The pinch 85 configured in this manner functions as a member (corresponding to the sealing member in the present invention) that seals the tube inlet of the bag 71. More specifically, a small opening (tube introduction port) is formed at the tip of the bag 71, and the tip 75a of the tube 75 is inserted into the bag 71 through the opening. And the said pinch 85 is mounted | worn so that the front-end | tip part 75a of the bag 71 and the tube 75 may be pinched | interposed by the clamping parts 91 and 91 from the outer side of the bag 71. FIG. The bag 71 is also thin and easily deformed. On the other hand, unlike the portions other than the tip portion, the tip portion 75a of the tube 75 is configured by a hard tube that is not easily crushed even when pressed from the side. Therefore, when the bag 71 and the distal end portion 75a of the tube 75 are sandwiched from the outside of the bag 71 by the sandwiching portions 91, 91 of the pinch 85, the distal end portion 75a of the tube 75 is not crushed, and the bag 71 is crushed. As a result, the portion sandwiched between the sandwiching portions 91, 91 is sealed leaving the lumen of the tube 75. Therefore, if carbon dioxide is supplied into the bag 71 via the tube 75 in this state, carbon dioxide will not leak from the opening (tube inlet) at the tip of the bag 71. Further, the tube 75 can be pulled out of the bag 71 with the pinch 85 attached. When the tube 75 is pulled out, the holding portions 91 and 91 that have been deformed into the shape along the side surface of the tube 75 are restored, and the space through which the tube 75 has passed is filled with the holding portions 91 and 91. Therefore, even if the tube 75 is pulled out, carbon dioxide does not leak from the opening (tube inlet) at the tip of the bag 71.

  With such a structure, after the tube 75 is used for supplying carbon dioxide, it can be removed from the bag 71. Therefore, even if the patient moves the foot, the tube 75 and the carbon dioxide supply source are moved. There is no such thing.

  Even with the carbon dioxide treatment device as described above, by sending carbon dioxide into the bag 71, the same operation and effect as the devices described in the above embodiments can be obtained. Can be implemented.

  Further, since the tube 75 can be pulled out and carbon dioxide does not leak out even if the tube 75 is pulled out, there is a problem even if the patient moves somewhat by removing the tube 75 after filling the bag 71 with carbon dioxide. You can prevent it from happening.

  Further, since the cover 71 prevents the bag 71 from being excessively expanded, even when a large bag that allows the affected part to be taken in and out is used as the bag 71, it is not necessary to be filled with carbon dioxide excessively.

As mentioned above, although embodiment of this invention was described, this invention is not limited to said specific one Embodiment, In addition, it can implement with a various form.
For example, in the above-described embodiment 9, an example in which the opening of the bag 71 is sealed with the pinch 85 when the tube 75 is pulled out is shown, but any sealing structure can be used as long as the opening of the bag can be sealed. You may adopt.

  For example, a check valve 95 as shown in FIG. 9B may be provided at the opening of the bag 96, for example. The check valve 95 is formed by stacking two thin and tensioned film materials and keeping the inner surfaces in close contact with each other in the heat-sealed portions 97 and 98 indicated by hatching in FIG. 9B. It is heat-sealed. Carbon dioxide can be supplied into the bag 96 by inserting a tube (not shown) between the heat fusion portions 97 and 98 of the check valve 95. In addition, after supplying the carbon dioxide into the bag 96, when the tube is pulled out from between the heat fusion portions 97 and 98, the two thin and tensioned film materials return to a state in which the inner surfaces are in close contact with each other. The leakage of carbon dioxide can be prevented. Therefore, even if such a check valve 95 is employed instead of the pinch 85 shown in the ninth embodiment, the tube can be pulled out and removed.
