Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body pressurizer that pressurizes a body part with fluid pressure for massage or the like.

When traveling a long distance by using a vehicle such as an airplane or a car, if you continue to sit in the same posture, you are likely to feel fatigue in your hands and feet, and swelling is likely to occur. In particular, if you sit and do not move your legs, the thighs will be compressed and the blood flow will be poor, resulting in blood clots that clog the veins of the lungs and cause symptoms such as dyspnea and chest pain. be. If the clot travels to the brain or heart, it can cause serious symptoms such as stroke or heart attack. Various diseases developed by such a mechanism are called "economy class syndromes". Economy class syndrome has been reported to occur not only in vehicles but also in evacuation centers and temporary housing during disasters.

Economy Class Syndrome can be prevented by staying hydrated and moving your limbs regularly. However, vehicle seats typically do not have enough space to exercise. In addition, exercising in a vehicle can be a nuisance to surrounding passengers, so psychological hurdles are high. For this reason, measures to prevent economy class syndrome are often taken by massaging the lower extremities to improve blood flow. Several massage instruments for such applications have been proposed so far.

For example, in FIG. 2 of Patent Document 1, a band-shaped body 3b formed in a hollow balloon shape, a balloon 5 arranged on the sole, and a tubular body 4b for communicating the band-shaped body 3b and the balloon 5 are provided. A device (deep vein thrombosis prevention device 1B) is described. In the device for preventing deep vein thrombosis 1B of the same document, a balloon 5 placed on the sole of the foot is trampled while a belt-shaped body 3b is wrapped around the lower leg, and air A in the balloon 5 is forced into the belt-shaped body 3b through the tubular body 4b. By moving and inflating the band-shaped body 3b, the body is pressurized (see paragraphs 0028 to 0039 of the same document).

FIG. 1 of Patent Document 2 shows a plurality of air bags 10, 11, 12, 13, 14, and 15 wound around the lower limbs, an air supply pipe 4 connected to the air bags 10 to 15, and an air supply. Equipped with a compressor 1 that supplies air to a pipe 4, and solenoid two-way valves 7a, 8a, 7b, 8b, 7c, 8c that switch intake and exhaust of air for each of the air bags 10 to 15 via the air supply pipe 4. A device (air massager) is described. In this air massager, the air bags 10 to 15 are wrapped around the lower limbs, the compressor 1 is driven, and air is supplied from the compressor 1 to the air bags 10 to 15 through the air supply pipe 4 to expand the air bags 10 to 15. When inflated, it pressurizes the body (see paragraphs 0014-0029 of the same document).

However, the device for preventing deep vein thrombosis 1B of Patent Document 1 does not always exhibit a sufficient effect in improving blood flow. This is because, in order to improve blood flow, it is necessary to apply pressure step by step from one side of the body to the other (in the case of the lower extremities, apply pressure step by step from the lower side to the upper side). is considered to be effective, the deep vein thrombosis preventive device 1B of Patent Document 1 is such that when the balloon 5 is trampled, the air A spreads substantially uniformly over the entire belt-shaped body 3b wrapped around the lower leg. This is because the structure is such that the whole part of the body around which the belt-like body 3b is wrapped is simultaneously pressurized with the same degree of force.

On the other hand, the air massager of Patent Document 2, for example, sequentially inflates from the air bag 10 to the air bag 15 by controlling the solenoid two-way valves 7a, 8a, 7b, 8b, 7c, 8c. (see paragraphs 0016-0021 of the same document). However, the air massager of the document is provided with two-way solenoid valves 7a, 8a, 7b, 8b, 7c, and 8c and a compressor 1, which is large-scale and expensive. In addition, the air massager of the document is unsuitable as a portable device to be brought into a vehicle such as an airplane.

The present invention has been made to solve the above-mentioned problems, and it is possible to pressurize a plurality of parts of the body step by step, such as applying pressure step by step from one side of the body to the other side. It provides a body pressurizer that can be used. It is also an object of the present invention to realize this body pressurizer with a simple structure and make it suitable for portability.

The above issues are
A winding member for winding around a body part is provided with a plurality of fluid supply chambers,
A body pressurizer configured to pressurize the body part by supplying a fluid to a fluid supply chamber to inflate the fluid supply chamber,
Having a transfer channel that communicates different fluid supply chambers and transfers fluid between the different fluid supply chambers,
A pair of blocking members are provided on one side and the other side of the transfer channel for closing the transfer channel by approaching each other,
When the fluid is supplied to the fluid supply chamber connected to one end of the transfer channel, the fluid flows from the fluid supply chamber into the transfer channel, and the transfer channel is pressurized. The problem is solved by providing a body pressurizer characterized in that a pair of closing members provided in the body are separated from each other so that the transfer channels are in a communicating state.

In the body pressurizer of the present invention, the fluid is supplied to the fluid supply chamber connected to one end of the transfer channel (hereinafter sometimes referred to as the "one end fluid supply chamber"), and the fluid is supplied to the one end side. Until the pressure in the supply chamber increases to some extent, the transfer channel is blocked by the pair of closing members. (sometimes referred to as "fluid supply chamber"). On the other hand, when the fluid is supplied to the fluid supply chamber on the one end side, the fluid flows into the transfer channel from the fluid supply chamber on the one end side, and the transfer channel is put into a pressurized state. The closing member is separated to bring the transfer channel into a communicating state, and the fluid flows through the transfer channel from the fluid supply chamber on the one end side to the fluid supply chamber on the other end side. Therefore, a time difference can be provided between the time when the fluid supply chamber on the one end side starts expanding and the time when the fluid supply chamber on the other end side starts expanding. Therefore, in the body pressurizer of the present invention, by expanding a plurality of fluid supply chambers step by step, it is possible to pressurize a plurality of parts of the body step by step. Therefore, using the body pressurizer of the present invention, it is possible to improve blood flow.

In addition, the body pressurizer of the present invention has a simple mechanism in which the pair of closing members provided in the transfer channel are initially in a state of being close to each other, but are naturally separated from each other by the pressure of the fluid that has flowed into the transfer channel. , the transfer channel is switched from the closed state to the open state. Therefore, the plurality of fluid supply chambers can be expanded step by step without using a device such as a solenoid two-way valve employed in the massager of Patent Document 2 above. Additionally, no power is required to separate the pair of closure members. Therefore, the body pressurizer can be made compact and suitable for portability. Moreover, it can be made suitable not only for use in vehicles but also for use in evacuation shelters and temporary housing in the event of a disaster. Since the body pressurizer of the present invention has a simple structure, it can be provided at a low cost and is less prone to failure. Additionally, disposal of the body pressurizer is easy.

In the body pressurizer of the present invention, the pair of closing members can maintain a state of being close to each other until fluid flows into the transfer channel and the pressure of the transfer channel increases to some extent, and when the pressure of the transfer channel increases to a certain extent, the pair of closing members separates. It is not particularly limited as long as it does. For example, if the pair of blocking members are engageable with each other, initially, even though the pair of blocking members are engaged and the transfer channel is in a closed state, when the pressure in the transfer channel increases, The pair of blocking members may be disengaged by applying a force in a direction to separate them from each other, and the pair of blocking members may be separated from each other, so that the transfer flow path is in a communicating state. can.

However, in order to realize switching from the blocked state to the open state of the transfer channel by the above-described engagement structure, it is necessary to finely adjust the engagement force, which is not necessarily easy. It is also necessary to reengage the pair of closure members when switching the transfer channel from the open state to the closed state. In addition, as the device is used repeatedly, the engagement structure wears or breaks, which may make it impossible to switch the transfer channel from the closed state to the open state at a desired timing. Furthermore, in order to close the transfer channel by the engagement structure, it is necessary to provide a pair of blocking members inside the transfer channel.

Therefore, in the body pressurizer of the present invention, the pair of closing members is preferably a pair of magnets that are magnetically attached to each other. This is because if a magnet with an appropriate magnetic force is selected, the transfer channel can be easily switched from the blocked state to the open state. Also, when the transfer channel is changed from a pressurized state to a non-pressurized state, the magnetic force attracts the pair of closing members and approaches each other, and the transfer channel is naturally (automatically) returned to the closed state. In addition, when the pair of blocking members are made of magnets, there is no fear of wear or breakage, unlike the engagement structure described above, and even after repeated use, the transfer channel can be changed from the blocked state to the open state at the same timing as at the beginning. This is because it is possible to switch to Furthermore, since the magnets with different poles attract each other even if there is an object between them, the transfer channel can be blocked even if they are provided outside the transfer channel.

In the body pressurizer of the present invention, the number of fluid supply chambers is not particularly limited as long as it is two or more. If it is, the number is not particularly limited. However, in the body pressurizer of the present invention, in order to be able to pressurize a plurality of locations on the body in multiple stages, it is preferable to provide three or more fluid supply chambers, and at least three transfer channels. It is preferable to provide two or more fluid supply chambers so as to communicate with each other. In this way, when two or more transfer channels are provided, a pair of closing members is usually provided in each transfer channel. Thereby, the body part can be pressurized in three stages or more.

for example,
the fluid supply chamber,
a first fluid supply chamber disposed on the first stage of the winding member;
a second fluid supply chamber disposed on the second stage of the winding member;
a third fluid supply chamber disposed on the third stage of the winding member;
and a fourth fluid supply chamber arranged on the fourth stage of the winding member,
the transfer channel,
a first transfer channel for transferring fluid between the first fluid supply chamber and the second fluid supply chamber;
a second transfer channel for transferring fluid between the second fluid supply chamber and the third fluid supply chamber;
By constructing the third transfer channel for transferring the fluid between the third fluid supply chamber and the fourth fluid supply chamber, the body part can be pressurized in four stages.

In the body pressurizer of the present invention, there is no particular limitation as to how the fluid supply chambers and transfer channels are provided in the winding member for winding around the body part. For example, the fluid supply chamber and the transfer channel, which are separate members from the winding member, may be attached to the winding member afterward. However, in this case, the number of parts constituting the body pressurizer increases, and the manufacturing of the body pressurizer becomes troublesome. This trouble increases as the number of fluid supply chambers and the number of transfer channels increases. For this reason, it is preferable that the fluid supply chamber and the transfer channel are integrated with the winding member as described below.

That is, the winding member is composed of an outer sheet arranged on the outer surface side and an inner surface sheet arranged on the inner surface side. Partitioning is preferred. As a result, not only can the number of parts constituting the body pressurizer be reduced, but even if the number of fluid supply chambers and the number of transfer channels is large, those fluid supply chambers and transfer channels can be operated at once. Since they can be formed by welding at the same time, it is also possible to greatly reduce the labor required for manufacturing the body pressurizer. Therefore, it is also possible to reduce the manufacturing cost of the body pressurizer.

The body pressurizer of the present invention preferably includes a manually operated pump for pumping fluid to a fluid supply port provided in one of the fluid supply chambers. As a result, the body pressurizer can be a manual type that does not require electric power or the like. Therefore, the body pressurizer can be made easy to bring and use inside a vehicle such as an airplane.

As described above, the present invention provides a body pressurizer capable of stepwise pressurizing a plurality of parts of the body, such as stepwise pressurization from one side of the body to the other. it becomes possible to In addition, it is possible to realize this body pressurizer with a simple structure and make it suitable for portability.

A preferred embodiment of the body pressurizer of the present invention will be described more specifically with reference to the drawings. FIG. 1 is a diagram showing a state in which the body pressurizer 10 is being wrapped around the calf (body part). FIG. 2 is a diagram showing a state in which the body pressurizer 10 is being wrapped around the calf (body part).

The body pressurizer 10 of the present invention, as shown in FIGS. 1 and 2, is intended to be used by being wrapped around a body part. 1 and 2 show an example in which the body pressurizer 10 is wrapped around the calf. However, the body part around which the body pressurizer 10 of the present invention is wrapped is not limited to the calf. The body pressurizer 10 of the present invention can also be used by wrapping it around lower limbs such as thighs and feet (parts beyond ankles) and upper limbs such as upper arms and forearms.

Also, if the size of the body pressurizer 10 is made larger than those shown in FIGS. 1 and 2, it can be used by wrapping it around the waist or buttocks. In terms of preventing the economy class syndrome described above, it is more effective to wrap the body pressurizer 10 around the lower limbs. It has the effect of improving the skin tone and also has a massage effect.

FIG. 3 is a diagram showing a state in which the body pressurizer 10 is deployed and viewed from the outside. FIG. 4 is a diagram showing a state in which the body pressurizer 10 is deployed and viewed from the inside. The body pressurizer 10 of this embodiment comprises a winding member 11 and a manual pump 12, as shown in FIGS.

As shown in FIGS. 3 and 4, the winding member 11 is generally band-shaped, and as shown in FIGS. 1 and 2, it is a portion to be wound around a body part. A hook-and-loop fastener 11c is provided on the outer surface of the winding member 11 at one end in the longitudinal direction, and a hook-and-loop fastener 11d that can be fixed to the hook-and-loop fastener 11c is provided on the inner surface of the winding member 11 at the other end in the longitudinal direction. The hook-and-loop fasteners 11c and 11d allow the winding member 11 wound around the body part to be maintained in the state shown in FIG. In addition, it is also possible to adjust the tightening force of the winding member 11 on the body part by changing the fixing position of the hook-and-loop fastener 11d to the hook-and-loop fastener 11c.

Approximately the entire winding member 11 is formed in the shape of a hollow airbag, and as shown in FIGS. ₍ gas or _liquid ) are _{provided .} Fluid is supplied to the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ to pressurize the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ , and the fluid supply chamber α ₁ , _{.alpha..sub.2} , _{.alpha..sub.3} , _{.alpha..sub.4} , the body part around which the winding member 11 is wound can be pressurized.

The type of fluid supplied to the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ is not particularly limited as long as it is gas or liquid. However, if the fluids to be supplied to the fluid supply chambers α ₁ , α ₂ , α ₃ , and α ₄ are liquid, it is necessary to prepare a liquid supply source (such as a liquid tank), and the body pressurizer 10 is heavy and bulky. Become. In addition, for safety reasons, bringing liquids into the aircraft is restricted, so it is assumed that the body pressurizer 10 cannot be used in the aircraft because the supply source of the liquid cannot be brought into the aircraft.

Therefore, the fluid to be supplied to the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ is normally gas, and air is particularly preferred. Air is ubiquitous and can be easily obtained without providing a source of it (such as an air cylinder). Also in the body pressurizer 10 of this embodiment, air is supplied to the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ . Specifically, as shown in FIG. 3, a manual pump 12 (air supply bulb) is connected via a tube 13 to a fluid supply port 15 provided in the fluid supply chamber _α1 . The manual pump 12 is operated to take ambient air into the manual pump 12 and supply the taken-in air to the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ . This manual pump 12 can be easily operated even by elderly people.

Manual pump 12 may be replaced by another pump, such as an electric pump. However, when using an electric pump, it is necessary to secure electric power such as a commercial power source. However, it is difficult to secure a commercial power supply in a vehicle such as an airplane or in an evacuation area in the event of a disaster. In this respect, if the electric pump is driven by a battery, the above problem can be solved, but the pump becomes bulky and heavy. On the other hand, if the manual pump 12 is adopted as in the body pressurizer 10 of this embodiment, it is possible not only to eliminate the need to secure electric power but also to make the pump less bulky and lighter.

As described above, the number of fluid supply chambers α ₁ , α ₂ , α ₃ , and α ₄ provided in the winding member 11 is not particularly limited as long as it is two or more, but it is preferable to provide three or more chambers. . However, if the number of fluid supply chambers α ₁ , α ₂ , α ₃ , α ₄ is too large, the capacity of each fluid supply chamber α ₁ , α ₂ , α ₃ , α ₄ becomes small, It may become difficult to expand the respective fluid supply chambers α ₁ , α ₂ , α ₃ , and α ₄ , and it may become difficult to pressurize the body part around which the winding member 11 is wound.

Therefore, the number of fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ is normally 30 or less. The number of fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ is preferably 20 or less, more preferably 10 or less. In the body pressurizer 10 of this embodiment, the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ are divided into the first fluid supply chamber α ₁ , the second fluid supply chamber α 2 and the third fluid supply chamber α ₂ . It is composed of a fluid supply chamber _α3 and a fourth fluid supply chamber _α4 , and the number of fluid supply chambers _α1 , _α2 , _α3 , and _α4 is four.

The arrangement of the fluid supply chambers α ₁ , α ₂ , α ₃ , and α ₄ varies depending on the body part to be pressurized by the body pressurizer 10 and is not particularly limited. However, the body pressurizer 10 of the present invention is used by wrapping the winding member 11 around a rod-shaped body part such as a calf, and the respective fluid supply chambers α ₁ , α ₂ , α ₃ , α ₄ are formed in a longitudinal shape, and these fluid supply chambers α ₁ , α ₂ , α ₃ , and α ₄ are preferably arranged substantially parallel to the winding direction (rotating direction) of the winding member 11 . .

As a result, when the winding member 11 is wound around the body part, the respective fluid supply chambers α ₁ , α ₂ , α ₃ , and α ₄ are arranged to surround substantially the entire circumference of the body part in the circumferential direction. It becomes possible to apply pressure so as to tighten substantially the entire outer circumference of the body part in the circumferential direction. Also in the body pressurizer 10 of this embodiment, the respective fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ are formed in a longitudinal shape, and the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ are arranged so as to be substantially parallel to the winding direction (wound direction) of the winding member 11 .

Specifically, the first fluid supply chamber _α1 is provided _in a strip shape along the lower edge of the winding member 11 in FIG. A second fluid supply chamber _α2 is provided in a strip shape above the second fluid supply chamber _α2 , a third fluid supply chamber _α3 is provided in a strip shape above the second fluid supply chamber α2, and the third fluid supply chamber _α3 A fourth fluid supply chamber _α4 is provided in a strip shape on the upper side of the . The fourth fluid supply chamber _α4 is provided along the upper edge of the winding member 11 in FIG. 3 as viewed in the drawing.

As already mentioned, the body pressurizer 10 of this embodiment is intended to be used by being wrapped around the calves, and the calves are thin on the lower side and thicker on the upper side. For this reason, the winding member 11 is formed in a fan shape so that its upper edge is longer than its lower edge, and the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ are also formed in a fan shape (arc shape). are doing. Therefore, the total length (length along the longitudinal direction) of the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ gradually increases from the first fluid supply chamber α ₁ to the fourth fluid supply chamber α ₄ . It is designed to be

In addition, the winding member 11 is provided with a device for communicating the different fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ to transfer the fluid between the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ . Transfer channels β ₁ , β ₂ , β ₃ are provided. The number of transfer channels β ₁ , β ₂ , β ₃ is appropriately determined according to the number of fluid supply chambers α ₁ , α ₂ , α ₃ , α ₄ . In order to connect all the fluid supply chambers α ₁ , α ₂ , α ₃ , α ₄ with the transfer channels β ₁ , β ₂ , β ₃ , the number of transfer channels β ₁ , β ₂ , β ₃ is The number of fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ must be one less than the number of fluid supply chambers α 1 , α 2 , α 4 .

In the body pressurizer 10 of this embodiment, the transfer flow paths β ₁ , β ₂ , and β ₃ are the first transfer flow paths that communicate the first fluid supply chamber α ₁ and the second fluid supply chamber α ₂ . a passage _β1 , a second transfer passage _β2 communicating between the second fluid supply chamber _α2 and the third fluid supply chamber _α3 , the third fluid supply chamber _α3 and the fourth fluid supply A total of three channels are provided, including the third transfer channel _β1 communicating with the chamber _α4 .

Each transfer channel β ₁ , β ₂ , β ₃ may be provided to connect the longitudinal ends of the fluid supply chambers α ₁ , α ₂ , α ₃ , α ₄ , but the body of the present embodiment In pressurizer 10, fluid supply chambers α ₁ , α ₂ , α ₃ , and α ₄ are provided so as to connect the central portions in the longitudinal direction. As a result, from certain fluid supply chambers α ₁ , α ₂ , α 3 and α ₄ to other fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ through certain transfer channels β ₁ , β ₂ and _{β 3 .} It is possible to make it easier for the fluid that has flowed in to quickly spread from the center to both ends of the other fluid supply chambers α ₁ , α ₂ , α ₃ , and α ₄ .

The method of providing the fluid supply chambers α ₁ , α ₂ , α ₃ , α ₄ and the transfer channels β ₁ , β ₂ , β ₃ to the winding member 11 is not particularly limited. For example, bag-like members forming fluid supply chambers α ₁ , α ₂ , α ₃ , and α ₄ and transfer channels β ₁ , β ₂ , and β ₃ are formed on a planar member forming the winding member 11 . A tubular member may be attached. However, in this case, the number of parts constituting the body pressurizer 10 increases. Therefore, in the body pressurizer 10 of this embodiment, the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ and the transfer flow paths β ₁ , β ₂ and β ₃ are integrated with the winding member 11 . are provided.

That is, as shown in FIG. 5 to be described later, the winding member 11 is composed of an outer surface sheet 11a arranged on the outer surface side and an inner surface sheet 11b arranged on the inner surface side, and the outer surface seal 11a and the inner surface seal 11b are welded at predetermined locations (in the body pressurizer 10 of this embodiment, the welded portions γ indicated by diagonal hatching in FIGS. 3 and 4), the fluid supply chambers α ₁ , α ₂ , α ₃ , α ₄ and transfer channels β ₁ , β ₂ , β ₃ .

In other words, of the overlapped portion of the outer sheet 11a (Fig. 3) and the inner sheet 11b (Fig. 4), the portion surrounded by the welded portion γ (the outer sheet 11a and the inner sheet 11b are not welded) places) are fluid supply chambers α ₁ , α ₂ , α ₃ , α ₄ and transfer channels β ₁ , β ₂ , β ₃ . As a result, a plurality of fluid supply chambers α ₁ , α ₂ , α ₃ , α ₄ and a plurality of transfer channels β ₁ , β ₂ and _β3 can be formed simultaneously.

In the body pressurizer 10 of this embodiment, most of the welding part γ is a linear welding part _γ1 having a thin linear shape, and the center section of the winding member 11 (the part excluding both longitudinal ends) ) become the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ . Therefore, it is possible to effectively pressurize body parts over a wide range in the center section of the winding member 11 .

However, the portions on both sides of the welded portion γ sandwiching the transfer flow paths β ₁ , β ₂ , and β ₃ are planar welded portions wider than the linear welded portion γ ₁ , as shown by the enlarged extracted portions in FIG. _γ2 . This planar welded portion _γ2 not only increases the welding strength of the welded portion γ, but also a pair of closing members 14 (described later).

One side closing member 14a and other side closing member 14b
) are brought closer to each other, the transfer channels β ₁ , β ₂ , and β ₃ are easily closed.

The outer sheet 11a and the inner sheet 11b are generally flexible synthetic resin sheets. Examples of the method for welding the outer sheet 11a and the inner sheet 11b at the welding portion β include thermal welding (heat sealing), ultrasonic welding, and high-frequency welding. In the body pressurizer 10 of this embodiment, the outer sheet 11a and the inner sheet 11b are welded together by thermal welding.

FIG. 5 is a cross-sectional view showing a state in which the periphery of the first transfer flow path β ₁ (part A in FIG. 4) of the body pressurizer 10 is cut along the ZZ plane (FIG. 4). FIG. 3B is a diagram showing a case where the transfer channel _β1 is in a closed state and (b) a case where the transfer channel _β1 is in a communicating state; In FIG. 5, the transfer channel _β1 is a gap between the outer sheet 11a and the inner sheet 11b, and is a portion located between points _P1 and _P2 in the figure.

As _shown in FIG. 5, a pair of blocking members 14 (one side blocking member 14a and The other side closing member 14b) is provided. The closing member 14 (the one side closing member 14a and the other side closing member 14b) is not supplied with fluid to either the first fluid supply chamber _α1 or the second fluid supply chamber _α2 , and the transfer flow is When no fluid is flowing into _the channel _β1 (when the transfer channel _β1 is not pressurized), as shown in FIG. state that fluid cannot pass through).

On the other hand, when the fluid is supplied to either one of the first fluid supply chamber _α1 and the second fluid supply chamber _α2 and the fluid flows into the transfer channel _β1 (the transfer channel _β1 is pressurized 5B, the pair of blocking members 14 (one side blocking member 14a and the other side blocking member 14b) are separated from each other by the pressure of the fluid that has flowed into the transfer channel _β1 , as shown in FIG. 5(b). It is designed to be in a state where In addition to _the first transfer channel _β1 , _a pair of is provided with a closing member 14 (one side closing member 14a and the other side closing member 14b).

Therefore, no fluid is supplied to any of the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ , and all the fluid supply chambers α ₁ , α ₂ , α ₃ and α ₄ are in a non-pressurized state. When , all the transfer channels β ₁ , β ₂ , and β ₃ are closed, but the fluid is supplied to the first fluid supply chamber _{α 1} When the fluid flows into _the first transfer channel _β1 from the first transfer channel β1, and the pressure in the first transfer channel _β1 rises to some extent, the pair of blocking members 14 (one-sided blocking The member 14a and the other-side blocking member 14b) are naturally separated to bring the first transfer channel _β1 into communication, and through this first transfer channel _β1 , the fluid flows from the first fluid supply chamber _α1 to the second fluid supply chamber α1. The fluid is transferred to the fluid supply chamber _α2 of the .

Further, the fluid transferred from the first fluid supply chamber _α1 to the second fluid supply chamber _α2 through the first transfer channel _β1 flows into the second transfer channel _β2 , and the second transfer flow When the pressure in the path _β2 rises to a certain level, the pair of blocking members 14 (the one side blocking member 14a and the other side blocking member 14b) provided in the second transfer flow path _β2 are naturally separated to perform the second transfer. The _{channel β2} is in a communicating state, and the fluid is transferred from the second fluid supply chamber _α2 to the third fluid supply chamber _α3 through the second transfer channel β2.

Where in the first fluid supply chamber _α1 the fluid supply port ₁₅ is provided is not particularly limited. A supply port 15 is provided so that the fluid supplied from the fluid supply port 15 to the first fluid supply chamber _α1 spreads quickly throughout the first fluid supply chamber _α1 .

A pair of blocking members 14 (one side blocking member 14a and the other side blocking member 14b) provided in each of the transfer channels β ₁ , β ₂ , β ₃ are arranged such that the pressure in the transfer channels β ₁ , β ₂ , β ₃ is reduced to some extent. There is no particular limitation as long as they can maintain a state of being close to each other until the pressure increases, and separate when the pressure in the transfer channels β ₁ , β ₂ , and β ₃ increases to some extent. As already mentioned, the pair of closing members 14 (the one side closing member 14a and the other side closing member 14b) may use an engaging structure. Subtle adjustment (so that the pair of blocking members 14 (the one side blocking member 14a and the other side blocking member 14b) separate when the pressures of the transfer flow paths β ₁ , β ₂ , and β ₃ rise to the target values and that the one _- side closing member 14a and the other-side closing member _14b are naturally ₍ automatically There are problems that the engaging parts are not engaged (need to be engaged manually), that they are easily worn and damaged, and that the engaging parts are inside the transfer channels β ₁ , β ₂ , β ₃ . There arises a problem that it is necessary to provide a

In this regard, in the body pressurizer 10 of the present embodiment, the pair of closing members 14 (one side closing member 14a and the other side closing member 14b) are combined with magnets (a pair of magnets arranged so that different poles face each other). By doing so, the above problems are solved. That is, it is easy to separate the pair of blocking members 14 (one side blocking member 14a and the other side blocking member 14b) when the pressures of the transfer channels β ₁ , β ₂ , and β ₃ increase to the target values. In addition, when the transfer channels β ₁ , β ₂ , and β ₃ change from the pressurized state to the non-pressurized state, the transfer channels β ₁ , β ₂ , and β ₃ naturally (automatically) The pair of closing members 14 (the one side closing member 14a and the other side closing member 14b) are made to be resistant to wear and damage, and the pair of closing members 14a and 14b as shown in FIG.
