[First Embodiment]
Hereinafter, the medical suction device 100 according to the first embodiment of the present invention will be described with reference to the drawings with reference to FIGS. 1 to 5 as appropriate. As shown in FIG. 1, the medical suction device 100 includes a suction device main body 10, an exhaust adjusting unit 20, and a compressor 30. In the present embodiment, one compressor 30 and an exhaust adjusting unit 20 are connected to each of the two suction device main bodies 10 via a piping tube 15.

The compressor 30 compresses the outside air to generate compressed air. This compressed air is sent to each of the two suction device main bodies 10 via the piping tube 15. As will be described in detail later, the suction device main body 10 is attracted and held on the affected portion of the patient by the flow of the compressed air. The exhaust adjusting unit 20 has another flow path 243 branching from the flow path 243 toward each suction device main body 10 from the compressor 30, and an adjusting valve 21. By adjusting (opening) the opening degree of the adjusting valve 21, a part of the compressed air generated by the compressor 30 is discharged to the outside. As a result, the flow rate of the compressed air supplied from the compressor 30 to the suction device main body 10 is adjusted, and the suction force of the suction device main body 10 with respect to the affected portion is appropriately adjusted.

Hereinafter, the detailed configuration of each of the above members will be described. The suction device main body 10 includes a suction cup 11 formed in a cup shape, an electrode member 12 provided inside the suction cup 11, a support member 13 for supporting the top of the suction cup 11, and the support member 13. It has a suction pin 14 (suction / exhaust unit 14) provided inside.

The suction cup 11 serves to accommodate the electrode member 12 so as to be separated from the affected portion or in close contact with the affected portion. As shown in FIGS. 1 and 2, the suction cup 11 has a substantially truncated cone-shaped outer shape that gradually expands in diameter from the top to the bottom, and has a top opening 111 and a bottom opening 112 at the top and bottom. (Opening 112) are formed respectively. Further, on the inner peripheral surface 113 of the suction cup 11, six ribs 114 extending in the generatrix direction are provided at predetermined intervals in the circumferential direction. As shown in FIG. 1, the suction cup 11 configured in this way has the edge portion of the top opening 111 supported by the support member 13.

Further, the suction cup 11 is integrally formed of translucent silicone rubber. At the time of the treatment, the affected part is covered with the opening 112 formed on one side of the suction cup 11 (that is, the side facing the affected part at the time of the treatment).

The support member 13 has a fitting portion 131 that fits into the top opening 111 of the suction cup 11, and a substantially cylindrical outer peripheral wall that opens toward the side opposite to the suction cup 11 when viewed from the fitting portion 131. It has 132 and a lid member 133 that closes the opening of the outer peripheral wall 132.

As shown in FIG. 3, the fitting portion 131 has a substantially cylindrical base portion 134, a flange-shaped first flange portion 135 extending on the outer periphery of the base portion 134, and a distance between the first flange portion 135 and the base portion 134 in the axial direction. It has a second flange portion 136 provided with a gap between the two. The first flange portion 135 is provided on the side closer to the suction cup 11 than the second flange portion 136. The edge of the top opening 111 of the suction cup 11 is fitted into an annular groove formed by the first flange 135 and the second flange 136. A partition wall portion 137 is provided in the radial inner region of the second flange portion 136. The partition wall portion 137 separates the suction cup 11 side of the support member 13 from the suction pin 14 side, which will be described later.

The outer peripheral wall 132 opens on the second flange portion 136 toward one side in the axial direction of the base portion 134 (that is, the side opposite to the suction cup 11). The lid member 133 is a disk-shaped member that closes the opening of the outer peripheral wall 132. Further, two openings (external exhaust port 138) that communicate with each other inside and outside are formed in a part of the outer peripheral wall 132. As shown in FIG. 2, these external exhaust ports 138 are provided at positions separated from each other in the radial direction on the outer peripheral wall 132.

Among the members of the support member 13 configured in this way, the partition wall portion 137, the outer peripheral wall 132, and the lid member 133 are sound absorbing portions 40 that cover the suction pin 14 (described later) from the outside. Further, the space formed by the partition wall portion 137, the outer peripheral wall 132, and the lid member 133 is a sound absorbing space 41.

The electrode member 12 plays a role of closely contacting the affected portion and energizing. The electrode member 12 is a plate-shaped member formed of a conductive material such as copper. The electrode member 12 is located at the center in the height direction of the suction cup 11 by being supported from above by the support member 13.

The suction pin 14 is a tubular member that allows air to flow in and out of the inside of the suction cup 11. As shown in FIG. 1, the suction pin 14 has a flow passage 141 formed therein, the opening on one end side thereof is an inflow port 142, and the opening on the other end side is an exhaust port 143. An orifice 144 having a smaller cross-sectional area than other regions is locally formed on the flow passage 141.

The suction pin 14 configured in this way is arranged inside the support member 13 so that the flow passage 141 thereof is substantially orthogonal to the axial direction of the suction cup 11. The inflow port 142, which is an opening on one end side of the suction pin 14, is connected to the compressor 30 via a piping tube 15. On the other hand, the exhaust port 143, which is the opening on the other end side, is exposed to the outside of the support member 13. Further, the suction pin 14 is formed with a suction port 145 that opens toward the suction cup 11 side in a substantially orthogonal direction (that is, the axial direction of the support member 13) across the flow passage 141.

With the above configuration, the compressed air exhausted from the exhaust port 143 of the suction pin 14 is guided into the sound absorbing space 41. At this time, the compressed air exhausted from the exhaust port 143 causes a scraping noise with the surroundings. As will be described in detail later, this scraping sound is absorbed or diffused in the sound absorbing space 41.

As the compressor 30, a suitable mode is appropriately selected from various devices capable of compressing external air to generate compressed air, based on design values such as a flow rate and a compression ratio. ..

As shown in FIG. 1, the exhaust adjusting unit 20 is a valve device (adjusting valve 21) connected to the compressor 30 and the suction device main body 10 via the piping tube 15. In the present embodiment, the solenoid valve shown in FIG. 4 or FIG. 5 is used as such a regulating valve 21. The regulating valve 21 is connected to a solenoid main body 22 having a pin 23 that moves forward and backward by an electric signal, a valve portion 24 integrally provided on one end side of the solenoid main body 22, and a part of the valve portion 24. It is provided with a silencer tube 25 (second sound absorbing portion 25).

More specifically, as shown in FIG. 5, the valve portion 24 includes a valve body 241 having a flow path 243 formed therein, and a valve body 242 for adjusting the flow state (opening) of the flow path 243. ing. The valve body 241 is a member formed in a substantially box shape in an external view, and is communicated with a substantially L-shaped flow path 243 in a cross-sectional view and the flow path 243, which will be described later. A storage space 244 for accommodating the valve body 242 is formed. One end of the flow path 243 is an introduction port 245 that opens outward. A piping tube 15 extending from the compressor 30 is connected to the introduction port 245. That is, compressed air flows into the above-mentioned flow path 243 through the introduction port 245.

On the other hand, of both ends of the flow path 243, the end (valve seat 246) on the side opposite to the introduction port 245 can be closed by the valve body 242. The valve body 242 is integrally connected to the pin 23 of the solenoid body 22 described above. That is, the valve body 242 also moves in one direction as the pin 23 moves forward and backward. When the pin 23 moves to the solenoid body 22 side, the valve body 242 is separated from the valve seat 246 to enable the flow of compressed air guided from the introduction port 245. In the following description, this state is referred to as an open state of the regulating valve 21.

On the other hand, when the pin 23 moves in the direction away from the solenoid main body 22, the valve body 242 comes into contact with the valve seat 246 to block the flow of compressed air. In the following description, this state is referred to as a closed state of the regulating valve 21. The amount of movement of the pin 23 can be adjusted steplessly or stepwise based on an electric signal input from the outside.

Further, a second exhaust port 247 is formed in a part of the accommodation space 244. The second exhaust port 247 is an opening that communicates the accommodation space 244 with the outside. That is, when the regulating valve 21 is in the open state, the compressed air that has flowed into the accommodation space 244 is exhausted to the outside through the second exhaust port 247.

Further, a silencer tube 25 as a second sound absorbing portion 25 is connected to the outside of the second exhaust port 247. In the present embodiment, the silencer tube 25 is a substantially columnar member fixed by a screw or the like provided on the outer edge of the second exhaust port 247. The silencer tube 25 is formed to be hollow, so that the internal space thereof is the second sound absorbing space 411. That is, the scraping sound with the surroundings generated when air is exhausted from the second exhaust port 247 is absorbed or diffused in the second sound absorbing space 411 of the silencer tube 25.

Next, an example of the handling method of the medical suction device 100 according to the embodiment of the present invention and the operation will be described.
First, in the state before use of the medical suction device 100, as shown in FIG. 3, the electrode member 12 is located at the central portion in the height direction of the suction cup 11 (that is, the central portion in the axial direction of the suction cup 11). doing. Therefore, even if the bottom of the suction cup 11 comes into contact with the human body, the electrode member 12 provided inside the suction cup 11 does not come into contact with the human body.

On the other hand, when using the medical suction device 100, the user first presses the suction cup 11 against the affected portion while visually recognizing the inside of the translucent suction cup 11. Then, by operating the compressor 30, the user blows compressed air from the inflow port 142 into the inside of the flow passage 141 via the piping tube 15. After passing through the orifice 144, the blown compressed air flows out from the exhaust port 143 to the outside of the suction pin 14. Here, when the air passes through the orifice 144, the air flow in the space surrounded by the suction cup 11 and the affected portion flows through the suction port 145 to the exhaust port 143 according to the so-called Bernoulli's theorem. Occur. As a result, the inside of the suction cup 11 becomes a state close to vacuum, and a suction force is generated inside the suction cup 11, so that the suction cup 11 is sucked to the affected part. Here, since the bottom of the suction cup 11 is made of silicone rubber, congestion is unlikely to occur in the affected area even if it is adsorbed on the affected area for a long time.

When the suction cup 11 is attracted to the affected portion and a sufficient suction force is generated inside the suction cup 11, the bottom portion of the suction cup 11 is in the height direction (that is, the axial direction of the suction cup 11). Elastically deforms to collapse. As a result, the electrode member 12 provided inside the suction cup 11 comes into contact with the affected area via a sponge (not shown) containing water, so that electrical treatment by energizing the affected area is started.

The suction cup 11 is structurally reinforced by providing six ribs 114 on the inner surface thereof to give a certain degree of waist. Therefore, even if the internal suction force increases, the suction cup 11 retains a substantially truncated cone-shaped outer shape to some extent.

When the use of the medical suction device 100 is terminated, the two external exhaust ports 138 formed on the outer peripheral wall 132 are closed with fingers or the like. Then, the air blown from the compressor 30 into the flow passage 141 flows into the inside of the suction cup 11 through the suction port 145. As a result, the suction force is lost inside the suction cup 11, so that the suction cup 11 can be easily removed from the affected area. As described above, the treatment by the medical suction device 100 is completed.

Here, the compressed air guided to the suction pin 14 is continuously exhausted to the outside through the exhaust port 143 during the treatment by the medical suction device 100. If the noise caused by this exhaust (scratching noise with surrounding members and the outside air) continues, there is a concern that it may damage not only the patient but also the environment of the medical field where quietness is required.

However, according to the above configuration, the exhaust sound generated at the exhaust port 143 of the suction pin 14 is absorbed in the sound absorbing space 41. As a result, the possibility that the exhaust noise is diffused to the surroundings can be reduced. More specifically, the compressed air exhausted through the exhaust port 143 temporarily stays in the sound absorbing space 41 and then is exhausted to the outside through the external exhaust port 138. At this time, in the sound absorbing space 41, the energy of the exhaust sound at the exhaust port 143 is absorbed and diffused. As a result, the loudness of the exhaust noise at the external exhaust port 138 becomes relatively small compared to the loudness of the exhaust noise at the exhaust port 143.
As described above, in the medical suction device 100 according to the present embodiment, the noise generated by the flow (exhaust) of the compressed air is reduced, so that the burden on the patient can be reduced.

Further, according to the above configuration, the exhaust sound generated at the second exhaust port 247 of the exhaust adjusting unit 20 is absorbed in the second sound absorbing space 411. As a result, the possibility that the exhaust noise is diffused to the surroundings can be further reduced. Further, in the present embodiment, a solenoid valve (adjustment valve 21) is applied as the exhaust adjustment unit 20. Therefore, by adjusting the opening degree of the adjusting valve 21, the amount of compressed air taken out to the outside through the exhaust adjusting unit 20 can be freely adjusted. Thereby, the suction force of the suction cup 11 with respect to the affected part can be made an appropriate size. In particular, by selecting an appropriate suction force according to the state of the surface of the affected portion, it is possible to reduce the burden on the affected portion due to the suction force of the suction cup 11.

The first embodiment of the present invention has been described above with reference to the drawings. However, the above description is merely an example, and various changes can be made to the above configuration. For example, not only a method of applying compressed air to the orifice 144 to apply a negative pressure, but also a vacuum pump (not shown) may be used to directly apply a negative pressure to the inside of the suction cup 11.

Further, it is also possible to arrange a foamable material such as a sponge as a sound absorbing material in the sound absorbing space 41 with the aim of further absorbing and diffusing the exhaust sound.

Further, in the above embodiment, the configuration including only one electrode member 12 has been described. However, the number of electrode members 12 is not limited to the above, and as shown in FIGS. 7 and 9 which will be referred to later, it is possible to adopt a configuration in which two or three or more electrode members 12 are provided.

[Second Embodiment]
Next, the second embodiment of the present invention will be described with reference to FIG. 6 or FIG. In the present embodiment, the outer peripheral wall 132 forming a part of the sound absorbing portion 40 is detachable from the support member 13 (or the suction / exhaust portion 14), which is different from the first embodiment described above. The configuration is different.

More specifically, as shown in FIG. 7, in the present embodiment, one side of the partition wall portion 137 of the support member 13 (that is, the side opposite to the suction cup 11 with respect to the partition wall portion 137) is substantially dish-shaped. The inner case 51 and the outer case 52 covering the inner case 51 are arranged respectively.

The inner case 51 is made of a resin material such as silicone. A first opening 53 through which the suction pin 14 is inserted and a second opening 54 communicating with an external exhaust port 138 formed in the outer case 52, which will be described later, are formed in a part of the inner case 51. There is. Further, the inner case 51 is removable from the partition wall portion 137 (support member 13).

The outer case 52 covers the inner case 51 from one side in the axial direction of the support member 13. That is, the outer case 52 also serves as the outer peripheral wall 132 and the lid member 133 in the second embodiment described above. Further, the outer case 52 is also detachable from the partition wall portion 137 (support member 13) like the inner case 51. With the above configuration, a space is formed inside the outer case 52 and the inner case 51. That is, a sound absorbing space 41 similar to that of the first embodiment is formed around the exhaust port 143 of the suction pin 14.

With the above configuration, the exhaust noise of the compressed air exhausted from the exhaust port 143 can be reduced. Specifically, the energy of the exhaust sound at the exhaust port 143 is absorbed and diffused in the sound absorbing space 41. As a result, the loudness of the exhaust noise at the external exhaust port 138 becomes relatively small compared to the loudness of the exhaust noise at the exhaust port 143. By reducing the noise in this way, it is possible to reduce the burden on the patient during treatment.

It is also possible to arrange a foamable material such as a sponge as a sound absorbing material in the sound absorbing space 41 with the aim of further absorbing and diffusing the exhaust sound.

[Third Embodiment]
Next, the medical suction device 100 according to the second embodiment of the present invention will be described with reference to FIGS. 8 to 11. The suction device main body 10 in the present embodiment is different from each of the above-described embodiments in the following points.

First, as shown in FIG. 8, in the suction device main body 10 of the present embodiment, the shape of the support member 13 is substantially rectangular in a plan view. Further, an external exhaust port 138 is formed in a part of the support member 13. The exhaust port 143 of the suction pin 14 is communicated to the outside through the external exhaust port 138. In other words, the sound absorbing space 41 and the sound absorbing portion 40 material in the above embodiment are not provided in the sound absorbing device main body in the present embodiment. As a result, the air exhausted from the exhaust port 143 is discharged to the outside through the external exhaust port 138. In the present embodiment, the cross-sectional shape (opening shape) of the external exhaust port 138 is substantially circular.

Further, a sound adjustment attachment 60 (sound adjustment unit 60) is fitted to the outside of the support member 13. As shown in FIG. 8 or 9, the tone adjustment attachment 60 connects a pair of holding portions 61 that abut on the long sides of the rectangular support member 13 that face each other and the ends of the pair of holding portions 61. It has a sound control unit main body 62 and.

As shown in FIG. 10 or 11, the sandwiching portion 61 is a resin plate-like member having substantially the same dimensions as the dimensions of the support member 13 in the longitudinal direction. In particular, three engaging protrusions 63 are formed on each of the pair of surfaces of the pair of holding portions 61 facing each other. The engaging protrusions 63 are arranged at intervals in the longitudinal direction of the holding portion 61. Each of these engaging protrusions 63 engages with an engaging recess (not shown) formed on the surface of the support member 13. That is, three engaging recesses are formed on each of the pair of side surfaces of the support member 13. By engaging each of the engaging protrusions 63 with these engaging recesses, the sound control attachment 60 is fixed to the support member 13 so as not to fall off.

The sound control unit main body 62 has a connection portion 64 for connecting the respective ends of the pair of sandwiching portions 61 in the longitudinal direction, and a sound control tube 65 provided at the central portion of the connection portion 64 in the longitudinal direction. ing.

As shown in FIG. 9 or 11, the sound control tube 65 is a substantially tubular member inserted into a tube fixing hole that penetrates the connection portion 64 in the thickness direction. A flow path 243 is formed inside the sound control tube 65. One end of the flow path 243 is an opening (tube opening 66) having a shape and dimensions corresponding to the external exhaust port 138. That is, in the present embodiment, the tube opening 66 has a substantially circular shape like the external exhaust port 138 described above.

On the other hand, the other end opening (tube exhaust port 67) of the flow path 243 has a cross-sectional shape (opening shape) different from that of the tube opening 66. More specifically, as shown in FIG. 11A, the tube exhaust port 67 has an oval shape extending in the longitudinal direction of the connection portion 64.

In the space between the tube opening 66 and the tube exhaust port 67, the compressed air exhausted from the external exhaust port 138 flows, and a sound control flow path 68 for changing the characteristics of the exhaust sound is used. ing. That is, the compressed air that has flowed into the sound control flow path 68 through the substantially circular tube opening 66 temporarily stays in the sound control flow path 68, and then is exhausted to the outside from the oval tube exhaust port 67.

According to the above configuration, the characteristics of the exhaust sound are changed by the air exhausted from the exhaust port 143 (external exhaust port 138) passing through the sound control flow path 68. More specifically, the exhaust noise at the tube exhaust port 67 is sufficiently reduced as compared with the exhaust noise when directly exhausted from the external exhaust port 138 by changing the frequency band, amplitude, and the like. .. This makes it possible to reduce the burden and discomfort on the patient due to the exhaust noise.

In particular, according to the above configuration, the tone control attachment 60 is removable from the support member 13. As a result, it can be easily attached to the existing suction device main body 10.

Further, when the sound control attachment 60 is attached to the support member 13, the three engaging protrusions 63 arranged in the longitudinal direction of the holding portion 61 engage with the engaging recesses provided on the support member 13 so that both of them are engaged. Is fixed. As a result, the sound adjustment attachment 60 can be easily positioned with respect to the support member 13. For example, if only one engaging protrusion 63 and an engaging recess are provided, the sound adjustment attachment 60 may rotate around the engaging protrusion 63 and the engaging recess. However, according to the above configuration, since the three engaging protrusions 63 (engaging recesses) are provided, the possibility of such rotation and misalignment can be reduced.

The sound adjustment attachment 60 may have the configurations shown in FIGS. 12 and 13 instead of the above configurations. In this example, when the support member 13 has a substantially circular cross-sectional shape, since the outer peripheral surface of the support member 13 is sandwiched, the pair of sandwiching portions 61 are substantially circular so as to correspond to the outer peripheral shape of the support member 13, respectively. It is curved in an arc shape.

Further, the tone control attachment 60 has a connector holding portion 90. The connector holding portion 90 is a member for suppressing the inadvertent detachment of the piping tube 15 by covering the tube connecting portion 80 from the surroundings. The tube connecting portion 80 has the piping tube 15 and an air connector 81 fixed to the end of the piping tube 15.

More specifically, as shown in FIG. 13, the connector holding portion 90 is provided with a sound control tube 65 out of one end edge of the pair of sandwiching portions 61 (that is, both end edges in the extending direction of the sandwiching portion 61). It is a substantially U-shaped member integrally provided on the edge on the side opposite to the side to be sewn. More specifically, the connector holding portion 90 includes a pair of extension portions 91 connected to the pair of holding portions 61, and an end edge between the pair of extension portions 91 (that is, a side separated from the holding portion 61). It has a retaining support portion 92 that connects the ends) to each other and supports the air connector 81 described later so as not to fall off.

The retaining support portion 92 extends in a direction substantially orthogonal to the extending direction of the extension portion 91. Further, the retaining support portion 92 has a pair of connecting portions 94 formed in a flat plate shape, and a semi-cylindrical tube fitting portion 93 provided between the connecting portions 94. The tube fitting portion 93 projects in an arc shape in a cross-sectional view from the extending plane of the connecting portion 94 in the normal direction.

Further, the end of the air connector 81 on one side is fixed to the piping tube 15, and the end on the other side is removable to the support member 13 of the suction device main body 10. As an example, the air connector 81 has a latch that is locked to one end of the suction pin 14, and a spring that locks the air connector 81 to the suction pin 14 by urging the latch. Can be considered.

According to the above configuration, the sound adjustment attachment 60 can be easily attached to the existing suction device main body 10, and the support member 13 is formed in a substantially disk shape. It is possible to sufficiently secure a room for forming the sound absorbing space 41 in each of the above embodiments.

Further, when the sound control attachment 60 is attached to the suction device main body 10, the connector holding portion 90 surrounds the air connector 81 provided at the connection portion with the piping tube 15 from the outer peripheral side as shown in FIG. Arranged like this. In particular, the lower half of the outer peripheral surface of the piping tube 15 is fitted to the tube fitting portion 93.

In addition, the air connector 81 has a larger outer diameter than the piping tube 15. As a result, the air connector 81 is held by the retaining support portion 92 so as not to be easily removed from the suction device main body 10. Therefore, as compared with the case where the tube connecting portion 80 is configured only by the locking device such as a spring built in the air connector 81 as described above, the air connector 81 may be inadvertently dropped from the suction device main body 10. It can be reduced. Further, even when the urging force and the restoring force of the spring as described above are lost due to a change with time, the air connector 81 can be stably held by the connector holding portion 90.

As another embodiment, the medical suction device includes a suction cup having a top opening at the top and a bottom opening at the bottom and gradually increasing in diameter from the top to the bottom, and the top opening. A partition wall that closes the portion, an outer peripheral wall that has a cylindrical shape that opens from the edge of the top opening toward the opposite side of the suction cup, and an external exhaust port that penetrates the inside and outside, and the outer circumference. It has a lid member that detachably closes the opening of the wall, a sound absorbing part that forms a sound absorbing space inside the partition wall, the outer peripheral wall, and the lid member, and an inflow port that is tubular and one end is exposed to the outside. The other end is an exhaust port that opens into the sound absorbing space, and the air in the space surrounded by the suction cup and the human body in contact with the bottom opening is sucked between the one end and the other end. It is provided with a suction / exhaust portion having a suction port formed therein, and an electrode member provided inside the suction cup that enables current to be supplied to the human body as a result of suction by the suction / exhaust portion.
In the above medical suction device, the direction in which air is exhausted from the external exhaust port may be different from the direction in which air is exhausted from the exhaust port. The medical suction device according to one aspect of the present invention includes a suction cup having a top opening at the top and a bottom opening at the bottom and gradually increasing in diameter from the top to the bottom, and the suction cup. From the suction port for sucking air in the space surrounded by the human body in contact with the bottom opening, and the suction / exhaust portion formed with the exhaust port for exhausting the air to the outside, and the exhaust port. A sound absorbing space formed around the exhaust port and a sound absorbing space for reducing the exhaust noise when the air is exhausted from the external exhaust port, which is a space into which the air flows, is provided inside the suction cup. An electrode member that enables current to be supplied to the human body as a result of suction by the suction / exhaust portion is provided, and the external exhaust port opens from the edge of the top opening toward the side opposite to the suction cup. It is formed so as to penetrate the outer peripheral wall having a cylindrical shape, and the direction in which the air is exhausted from the external exhaust port is different from the direction in which the air is exhausted from the exhaust port.
In the above medical suction device, two external exhaust ports may be formed at positions separated from each other in the radial direction of the outer peripheral wall.
In the medical suction device described above, the electrode member may be one that energizes the human body by contacting the human body via a sponge containing water.
