Description

Technical Field

[0001] The present invention relates to an enema device and an operation method thereof. More specifically, it relates to an enema device and an operation method thereof that can process the administration of an enema drug and the extraction of feces at once without leakage of feces to the outside.

Background Art

[0002] Enema refers to a procedure of injecting an enema solution into the large intestine to remove the intestinal contents for the purpose of relieving constipation or removing feces during surgery or childbirth. Generally, enema is performed due to abdominal pain caused by severe constipation, diagnosis of large intestine diseases, surgery for large intestine diseases, or for endoscopic procedures of the large intestine such as in patients with hepatic coma.

[0003] However, severely ill patients such as those with hepatic coma are unable to perform enema by themselves, so they are forced to undergo the procedure by nurses or the like. The enema procedure consists of inserting an enema drug and extracting the accompanying feces, but since each requires a separate procedure, it has been inconvenient. Also, it has been difficult to place severely ill patients in the posture required for enema depending on their body weight. And there has been a problem that feces leak outside the body of severely ill patients during enema. The technologies that are the background of the present invention are disclosed in Patent Documents 1-2: International Publication Patent WO2010 / 122537 and Korean Published Patent No. 2016-0117168.

[0021] Figure 1 schematically shows an exploded perspective view of an enema device 100 according to one embodiment of the present invention. The structure of the enema device 100 in Figure 1 is merely illustrative of the present invention, and the present invention is not limited thereto. Therefore, the structure of the enema device 100 in Figure 1 can be modified in different ways.

[0022] As shown in Figure 1, the enema device 100 includes an inner insertion tube 10 and an outer insertion tube 20. Both the inner insertion tube 10 and the outer insertion tube 20 are formed in the form of tubes. The inner insertion tube 10 includes a support rod 101. The support rod 101 extends in one direction, i.e., along the z-axis, so as to be inserted into the anus. The inside of the support rod 101 may be formed to be hollow.

[0023] The outer insertion tube 20 is detachable from the outside of the inner insertion tube 10. The outer insertion tube 20 extends along the z-axis. As a result, the support rod 101 is inserted into the outer insertion tube 20 along the dotted line, allowing the outer insertion tube 20 to surround the support rod 101. The outer insertion tube 20 includes a cylindrical tube 201. The cylindrical tube 201 has a lower strength than the support rod 101. For example, the cylindrical tube 201 may be made of silicone and the support rod 101 may be made of polypropylene. The outer insertion tube 20 is inserted into the anus for an enema. The outer insertion tube 20 comes into contact with the anus. Since the cylindrical tube 201 is made of soft silicone, the patient does not feel pain when the outer insertion tube 20 is inserted into the anus. In contrast, if the outer insertion tube 20 is made of a material with a certain strength, the patient may feel pain due to its strength when the outer insertion tube 20 is inserted into the anus. Therefore, the cylindrical tube 201 is made of silicone.

[0024] However, because the cylindrical tube 201 is manufactured from a relatively low-strength material, it may bend easily when inserted into the anus, making it difficult to insert the outer insertion tube 20. Therefore, the support rod 101 inserted into the cylindrical tube 201 can be used to reinforce the strength of the cylindrical tube 201 necessary for insertion into the anus. That is, the support rod 101 is manufactured from a material with higher strength than the cylindrical tube 201. As a result, when inserting the outer insertion tube 20 into the anus for an enema, the cylindrical tube 201 reinforces the strength of the outer insertion tube 20 and supports it so that it does not bend, thereby allowing the outer insertion tube 20 to be inserted into the anus more easily.

[0025] As shown in Figure 1, the inner insertion tube 10 further includes a mounting plate 103, a side portion 105, and a gripping column 107. A support rod 101 is connected to and mounted on the mounting plate 103. Therefore, the support rod 101 can be stably supported by the mounting plate 103. The mounting plate 103 has a circular shape and is located on the xy plane.

[0026] The side portion 105 is spaced apart from the support rod 101 in the xy-plane. The side portion 105 is formed in the form of a wall surrounding the circumference of the mounting plate 103. A first guide hole 1051 and a second guide hole 1053 are formed in the side portion 105. The first guide hole 1051 is formed open in one direction, i.e., along the z-axis. The second guide hole 1053 is connected to the first guide hole 1051. The second guide hole 1053 is formed in a direction perpendicular to the first guide hole 1051, i.e., along the x-axis.

[0027] The projection 2131 in Figure 1 moves sequentially along the first guide hole 1051 and the second guide hole 1053 in the direction of the arrow indicated by the dashed line, and is fixed to the end of the second guide hole 1053. That is, the inner insertion tube 10 inserted into the outer insertion tube 20 can be rotated to move the projection 2131 to the end of the second guide hole 1053. A convex portion 1055 is located protruding in the -z axis direction from the second guide hole 1053. Therefore, the projection 2131 is inserted inside the convex portion 1055 and is stably fixed by the convex portion 1055. As a result, the inner insertion tube 10 can be stably connected inside the outer insertion tube 20. Therefore, since the support rod 101 stably supports the cylindrical tube 201 made of a soft material, the enema device 100 can be easily inserted into the anus.

[0028] The gripping columns 107 protrude outward from the side portion 105 at equal distances from each other. Therefore, the user of the enema device 100 can easily connect the inner insertion tube 10 to the outer insertion tube 20 by grasping the gripping columns 107 with their hand and rotating the side portion 105. On the other hand, to avoid interference, the first guide hole 1051 and the second guide hole 1053 are located between the gripping columns 107.

[0029] As shown in Figure 1, the outer insertion tube 20 further includes a balloon 205, a plate-shaped member 207, a check valve casing 209 (shown in Figure 2), a guide ring 211, and a fastening member 213. In addition, the outer insertion tube 20 may further include other components.

[0030] The balloon 205 surrounds the middle side of the cylindrical tube 201. The balloon 205 is applied so as to inflate with the injected air and secure the outer insertion tube 20 to the anus. As a result, the outer insertion tube 20 can be stably placed on the anal muscles. For this purpose, the balloon 205 may be formed in the shape of a donut. A needle 60 is inserted between the balloon 205 and the cylindrical tube 201. The needle 60 communicates with the air injection tube 50.

[0031] An air inlet 501 is attached to one end of the air injection tube 50, and a needle 60 is connected to the other end. Although not shown in Figure 1, a syringe is connected to the air inlet 501, allowing air to be injected into the balloon 205 through the air injection tube 50 and the needle 60 using the syringe. The diameter d50 of the air injection tube 50 is larger than the diameter d60 of the needle 60. That is, a relatively large amount of air flows into the air injection tube 50 through the syringe, so it needs to have a volume large enough to withstand this. Therefore, the diameter d50 of the air injection tube 50 is made relatively large. On the other hand, since the needle 60 must be inserted between the balloon 205 and the cylindrical tube 201, its diameter d60 is made small to take that space into consideration.

[0032] Meanwhile, the plate-shaped member 207 is connected to one end of the cylindrical pipe 201. As the diameter of the cylindrical pipe 201 gradually increases, the cylindrical pipe 201 is naturally connected to the plate-shaped member 207. The diameter d207 of the plate-shaped member 207 is larger than the diameter d201 of the cylindrical pipe 201. Because the diameter d207 of the plate-shaped member 207 is larger than the diameter d201 of the cylindrical pipe 201, the plate-shaped member 207 stably supports the cylindrical pipe 201.

[0033] The fastening member 213 covers the check valve casing 209 (shown in Figure 2) and the guide ring 211, with its center passing through it. A projection 2131 is formed on the side surface of the fastening member 213. The projection 2131 can be inserted into the first guide hole 1051 along the direction of the dashed arrow to stably connect the inner insertion tube 10 and the outer insertion tube 20. For this purpose, the inner diameter d105 of the side surface 105 is slightly larger than the outer diameter d213 of the fastening member 213. For example, the difference between the inner diameter d105 and the outer diameter d213 may be greater than 0 and less than or equal to 0.2 mm. Because a fine gap is formed in this way, the fastening member 213 can be stably inserted and fixed within the side surface 105. The outer insertion tube 20 will be described in more detail below with reference to Figure 2.

[0034] Figure 2 schematically shows the disassembled structure of the outer insertion tube 20 included in the enema device 100 of Figure 1. The enlarged circle in Figure 2 shows the front view of the check valve 203 in the -z axis direction. The disassembled structure of the outer insertion tube 20 in Figure 2 is merely illustrative of the present invention and is not limited thereto. Therefore, the structure of the outer insertion tube 20 in Figure 2 can be modified in different ways.

[0035] As shown in Figure 2, the outer insertion tube 20 includes a cylindrical tube 201, a check valve 203, a balloon 205, a plate-shaped member 207, a check valve casing 209, a guide ring 211, and a fastening member 213. In addition, the outer insertion tube 20 may further include other components.

[0036] The check valve 203 can be manufactured from thin silicone. Therefore, the check valve 203 can be used to block the leakage of internal bodily contents such as feces or enema fluid in the -z axis direction. The check valve 203 is located inside the outer insertion tube 20. More specifically, the check valve 203 is located inside the check valve casing 209.

[0037] As shown in the enlarged circle in Figure 2, the check valve 203 includes adjacent check valve pieces 2031. Since each check valve piece 2031 is formed separately, they are adjacent to each other and form a cross-shaped opening and closing groove G. However, the cross-shaped opening and closing groove G is merely the minimum space required for each check valve piece 2031 to flow while minimizing contact with each other. Therefore, it is too narrow for a fluid with some viscosity to flow through the cross-shaped opening and closing groove G. Thus, the check valve 203 can prevent the contents of the body or enema fluid from leaking in the -z axis direction. Even while operating in this manner, because each check valve piece 2031 is formed separately, the enema fluid can be injected into the body by passing a syringe through the check valve 203.

[0038] Furthermore, the check valve 203 has a shape that is recessed in the direction of the -z axis, meaning that each check valve piece 2031 forms a pocket. Therefore, the check valve 203 has a shape that blocks the flow of fluid flowing in the direction of the -z axis, and can thus block the passage of fluid.

[0039] A through hole 2071 is formed in the plate-shaped member 207. The through hole 2071 is formed in contact with the outer surface of the check valve casing 209. In other words, since the through hole 2071 is not exposed to the outside and is located in contact with the outer surface of the check valve casing 209, durability can be ensured by preventing the air injection pipe 50 (shown in Figure 1) from being damaged by external impacts.

[0040] As shown in Figure 2, the check valve casing 209 is located opposite the cylindrical pipe 201, with the plate-shaped member 207 in between. The check valve casing 209 houses the check valve 203. The diameter d209 of the check valve casing 209 is larger than the diameter d201 of the cylindrical pipe 201, but smaller than the diameter d207 of the plate-shaped member 207 (shown in Figure 1). Therefore, the check valve casing 209 is stably housed below the plate-shaped member 207.

[0041] The guide ring 211 is attached to the underside of the check valve casing 209. The guide ring 211 includes a guide side portion 2111 and a support plate 2113. The guide side portion 2111 is formed on top of the support plate 2113. The guide side portion 2111 forms a hollow C1 whose diameter d2111 gradually decreases toward the check valve 203. The structure of the check valve 203 in Figure 2 will be described in more detail below with reference to Figure 3.

[0042] Figure 3 shows a schematic, enlarged view of the check valve 203 in Figure 2. The structure of the check valve 203 in Figure 3 is merely illustrative of the present invention and is not limited thereto. Therefore, the structure of the check valve 203 in Figure 3 can be modified in different ways. Although the check valve 203 in Figure 3 is shown as being located within the outer insertion tube 20 in Figure 1, it can also be installed in a tube (not shown) contained within an enema device, extending in one direction and having a hollow interior. The tube can communicate with the anus.

[0043] As shown in Figure 3, each check valve piece 2031 includes a first inclined surface 2031a and a second inclined surface 2031b. The first inclined surface 2031a and the second inclined surface 2031b are formed symmetrically to each other and are open in the +z-axis direction. Therefore, the first inclined surface 2031a and the second inclined surface 2031b have a shape that blocks the flow of fluid that may flow backward in the -z-axis direction.

[0044] One end 2031c of the first inclined surface 2031a and one end 2031d of the second inclined surface 2031b are formed in a straight line. Therefore, the ends 2031c and 2031d of the check valve piece 2031 meet each other to form a cross-shaped opening and closing groove G. On the other hand, the other end 2031e of the first inclined surface 2031a and the other end 2031f of the second inclined surface 2031b are formed in a curved line. The other ends 2031e and 2031f correspond to the circumference inside the cylindrical pipe 201. That is, the other ends 2031e and 2031f are fixed opposite the inner wall of the cylindrical pipe 201. As a result, the first inclined surface 2031a and the second inclined surface 2031b form a pocket space S that is recessed toward the cylindrical pipe 201 along with the circumference.

[0045] In other words, as shown in Figure 3, a pocket space S is formed in the +z axis direction, that is, toward the cylindrical tube 201 (shown in Figure 2). The pocket space S acts as a space that can contain enema fluid or internal body contents that leak from the anus in an emergency. As a result, leakage of such fluids can be prevented by using the check valve 203. The structure of the check valve 203 is described in more detail below.

[0046] The check valve 203 further includes a check valve support plate 2033 and a side surface 2035. The check valve support plate 2033 is formed in a hollow shape. The check valve support plate 2033 is attached to the underside of the check valve casing 209 (shown in Figure 2) to form a support structure. The side surface 2035 is connected to the check valve support plate 2033. The diameter of the side surface 2035 forms a hollow C2 that gradually decreases in the +x axis direction, i.e., as it approaches the cylindrical tube 201 (shown in Figure 2). The side surface 2035 is integrally formed surrounding the inner circumference of the check valve casing 209. The check valve pieces 2031 are formed on the side surface 2035 and adjacent to each other. The check valve pieces 2031 can be integrally formed with the side surface 2035. That is, the side surface 2035 can also be manufactured from thin silicon in the same manner as the check valve pieces 2031.

[0047] Figure 4 schematically shows the discharge tube 30 and storage container 40 included in the enema device 100 of Figure 1. The discharge tube 30 and storage container 40 in Figure 4 are merely illustrative of the present invention and are not limited thereto. Therefore, the discharge tube 30 and storage container 40 can be modified in different ways. The mounting plate 103, side portion 105, and gripping column 107 included in the discharge tube 30 of Figure 4 are the same as the mounting plate 103, side portion 105, and gripping column 107 included in the inner insertion tube 10 of Figure 1, so the same reference numerals are used and, for convenience, a detailed explanation is omitted. In this way, since the inner insertion tube 10 and the discharge tube 30 use the same parts as each other, not only can the manufacturing cost of the enema device 100 be reduced, but they can also be interchanged and attached to the outer insertion tube 20 during operation of the enema device 100 (shown in Figure 1).

[0048] As shown in Figure 4, the discharge pipe 30 extends in one direction, i.e., along the z-axis. The discharge pipe 30 includes a flexible discharge section 301, a fastening cover 303, a mounting plate 103, a side section 105, and a gripping column 107. In addition, the discharge pipe 30 may further include other components. For example, although not shown in Figure 4, a clip can be attached to the middle of the flexible discharge section 301 to press the flexible discharge section 301 and restrict the flow of fluid passing through it.

[0049] The discharge tube 30 is detachable from the outer insertion tube 20 (shown in Figure 1) through the side portion 105. That is, it can be attached to and detached from the outer insertion tube 20 (shown in Figure 1) in the same way as the inner insertion tube 10 (shown in Figure 1), which includes it, by utilizing the side portion 105. As a result, the flexible discharge section 301 communicates with the cylindrical tube 201 (shown in Figure 1). Therefore, internal bodily contents, such as feces, discharged from the anus can be continuously discharged through the flexible discharge section 301 via the cylindrical tube 201 (shown in Figure 1).

[0050] A fastening member 213 (shown in Figure 1) is attached to the mounting plate 103 to stably support the connection between the outer insertion pipe 20 and the discharge pipe 30. The mounting plate 103 is connected to one side of the flexible discharge section 301, and the fastening cover 303 is connected to the other side of the flexible discharge section 301. The side portion 105 is separated from the flexible discharge section 301. Threads 3031 are formed on the inner surface of the fastening cover 303. The discharge pipe 30 and the storage unit 40 can be firmly connected using the threads 3031. That is, the storage unit 40 can be attached to and detached from the discharge pipe 30 along the direction of the dotted arrow.

[0051] As shown in Figure 4, the storage container 40 includes a vinyl bag 401, an inlet 403, and a cap 405. In addition, the storage container 40 may further include other components.

[0052] As shown in Figure 4, the inlet 403 has threads 4031 formed on the inside of the fastening cover 303 that correspond to the threads 3031 formed on the inside of the fastening cover 303. The threads 3031 and 4031 are formed by intaglio or embossing respectively and are connected to each other so that the inlet 403 and the fastening cover 303 are firmly joined to each other so that the contents of the body do not leak out. The cap 405 can be attached to and detached from the inlet 403. That is, when the vinyl bag 401 connected to the inlet 403 is not used, the inlet 403 is closed using the cap 405. When the storage container 40 is connected to the discharge pipe 30 to collect the contents of the body that are discharged after the enema, the cap 405 is opened and the inlet 403 is fastened to the fastening cover 303. As a result, after the contents of the body that are discharged through the outer insertion tube 20 after the enema are collected in the vinyl bag 401 through the discharge pipe 30 so as not to leak out, the inlet 403 can be separated from the fastening cover 303 and the cap 405 can be closed and discarded as is. The operation method of this enema device 100 (shown in Figure 1) will be explained in detail below through Figures 5 to 12.

[0053] Figure 5 schematically shows a flowchart of the operation method of the enema device 100 shown in Figure 1. The operation method of the enema device 100 shown in Figure 5 is merely illustrative of the present invention and is not limited thereto. Therefore, the operation method of the enema device 100 shown in Figure 5 can be modified in different ways.

[0054] On the other hand, Figures 6 to 12 schematically show the operation process of the enema device at each stage of Figure 5. The operation processes of the enema device in Figures 6 to 12 are merely illustrative of the present invention and are not limited thereto. Therefore, each operation process of the enema device can be modified in different ways. Below, the operation method of the enema device 100 will be described in detail with reference to Figures 6 to 12, which correspond to each stage of Figure 5.

[0055] As shown in Figure 5, the operation method of the enema device 100 includes the steps of: inserting the inner insertion tube into the outer insertion tube, rotating the side portion to sequentially draw the projections into the first guide hole and the second guide hole and move them to fix the projections with the convex portion (S10); injecting air into the balloon to inflate it (S20); removing the inner insertion tube from the outer insertion tube (S30); injecting the enema solution by inserting the syringe through the check valve and then removing the syringe (S40); connecting the flexible discharge portion to the cylindrical tube (S50); separating the cap from the inlet and rotating the inlet to connect it to the inside of the fastening cover (S60); separating the inlet from the fastening cover and closing the fastening cover with the cap (S70); and removing the air from the balloon and removing the outer insertion tube (S80). In addition, the operation method of the enema device may further include other steps.

[0056] First, in step 5 (S10), the inner insertion tube 10 is inserted into the outer insertion tube 20, and the side portion 105 is rotated to sequentially draw in the projection 2131 into the first guide hole 1051 and the second guide hole 1053 along the direction of the arrow indicated by the dashed line, and fix it in place with the protrusion 1055 (illustrated in Figure 1). As a result, the inner insertion tube 10 and the outer insertion tube 20 are firmly and integrally joined to each other. Then, the inner insertion tube 10 and the outer insertion tube 20 are inserted into the anus for the enema. Since the outer insertion tube 20 contains a cylindrical tube 201 made of silicone, the patient does not feel much pain even when the outer insertion tube 20 is inserted into the anus and comes into contact with the outer insertion tube 20. On the other hand, since the cylindrical tube 201 is supported by a support rod 101 made of polypropylene contained in the inner insertion tube 10, the cylindrical tube 201 made of silicone does not bend or distort and can be easily inserted into the anus.

[0057] Returning to Figure 5, in step (S20), air is injected into the balloon 205 to inflate it (as shown in Figure 6). In its undintuitive state, the balloon 205 is located just inside the anus. A syringe (not shown) is connected to the air inlet 501, and the piston (not shown) is pushed to inject air into the balloon 205 through the air injection tube 50 and needle 60, causing the balloon 205 to inflate. As a result, the balloon 205 inflates into a donut shape, and the outer insertion tube 20 is stably positioned against the anal muscle.

[0058] In step 5 (S30), as indicated by the dotted arrow, the inner insertion tube 10 is removed from the outer insertion tube 20 (as shown in Figure 7). That is, the inner insertion tube 10 is removed to create space for injecting the enema solution. The balloon 205 inflates to securely position the outer insertion tube 20 in the anus.

[0059] In step 5 (S40), syringe Y is injected through the check valve to introduce enema fluid L into the anus (as shown in Figure 8). Then syringe Y is removed. Syringe Y may be the same syringe used in step (S20). Because the check valve 203 (not shown, the same applies hereafter) has a shape that bulges towards the anus, syringe Y can easily penetrate the check valve 203. In addition, the enema fluid injected into the anus through the outer insertion tube 20 does not leak to the outside due to the check valve 203.

[0060] Returning to Figure 5, in step (S50), the flexible discharge section 301 is connected to the outer insertion tube 20 (as shown in Figure 9). This prepares the body for the contents generated by the enema to be discharged through the flexible discharge section 301. The method for connecting the flexible discharge section 301 to the outer insertion tube 20 is the same as the method used in step (S10).

[0061] In step 5 (S60), the cap 405 is separated from the inlet 403, and the inlet 403 is rotated to connect to the inside of the fastening cover 303 (as shown in Figure 10). Alternatively, the fastening cover 303 may be rotated to connect to the inlet 403. As a result, the flexible discharge section 301 and the inlet 403 are securely fastened together without leakage. Since the flexible discharge section 301 is open before the inlet 403 is connected, a clip (not shown) can be placed in the middle of the flexible discharge section 301 to press the flexible discharge section 301 and prevent the contents of the body being discharged through the anus from leaking out. After such measures, the inlet 403 can be connected to the fastening cover 303. Then the clip can be removed and the contents of the body being discharged through the flexible discharge section 301 can be neatly collected in the plastic bag 401.

[0062] Returning to Figure 5, in step (S70), the inlet 403 is separated from the fastening cover 303, and the fastening cover 303 is closed with the cap 405 (indicated by an arrow in Figure 11). That is, since all the contents of the body expelled by the enema have been collected in the plastic bag 401, the cap 405 is closed and the storage container 40 is discarded.

[0063] Finally, in step (S80), the air is released from the balloon and the outer insertion tube 20 is removed from the anus (as shown in Figure 12). That is, a syringe (not shown) is connected to the air injection tube 50, and the air in the balloon 205 is removed through the air injection tube 50. As a result, the outer insertion tube 20 and the flexible discharge section 301 connected to it can be completely removed by pulling them in the direction of the arrow. It is also possible to remove the flexible discharge section 301 first and then remove the outer insertion tube 20. However, since the outer insertion tube 20 is made of a soft material and is short in length, in order to remove it easily from the anus, it is preferable to pull the flexible discharge section 301, which is firmly connected to the outer insertion tube 20 and has a long shape, so that the outer insertion tube 20 is also removed from the anus together.

[0064] The enema can be easily administered through the process described above. Furthermore, since the enema device according to one embodiment of the present invention is manufactured to encompass all stages of the enema process, it is extremely convenient to use.

Various modifications and improvements by persons skilled in the art, utilizing the basic concepts of this disclosure as defined in the following claims, also fall within the scope of rights of this disclosure.
