Description

Technical Field

[0001] The present invention relates to the field of defecation devices, and particularly to a defecation device for the digestive department. Background Art

[0002] The digestive department is a clinical department established for diagnosing and treating digestive system diseases. In the digestive department, there are often patients with intestinal problems. Some patients have constipation symptoms. For patients with mild symptoms, auxiliary defecation can be achieved through drug means. However, for patients with severe intestinal problems, their feces are highly hardened in the intestine, and the effect of drugs is not good. Currently, there is a lack of a tool to help patients with severe constipation defecate. Therefore, it is necessary to propose a defecation device to discharge the dry and hard feces in the body of patients with severe constipation. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the present invention proposes a defecation device for the digestive department to solve the problem of the lack of a tool to help patients with severe constipation defecate currently.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A defecation device for the digestive department provided by the present invention includes:

[0006] A cylinder body, one end of which is an open end, and a plurality of inwardly extending sliding grooves are circumferentially and evenly distributed on the inner wall of the open end;

[0007] A digging member, one is provided in each of the sliding grooves in a slidable manner. One end of the digging member is connected to the extending end of the sliding groove through an elastic member, and a driven part is further provided on one side of this end. The elastic member can provide an elastic force to make the digging member lean towards the extending end of the sliding groove. The other end of the digging member is located outside the open end and is provided with a digging part; and

[0008] A driving mechanism, which is installed in the cylinder body and is drivingly connected to each driven part. The driving mechanism can drive each digging member to slide outwards along the sliding groove.

[0009] Further, the driving mechanism includes a motor and a driving disk. The motor is installed at the bottom of the inner cavity of the cylinder body and the motor shaft faces the open end. The driving disk is installed on the motor shaft, and an annular groove body is provided on the side away from the motor. The path of the bottom of the annular groove body is alternately undulating in a wave shape, and the end of each driven part is in contact with the bottom of the annular groove body.

[0010] Further, the heights at which each driven part is in contact with the bottom of the annular groove body at the same time are all different.

[0011] Further, the path of each sliding groove is inclined based on the axis of the cylinder body.

[0012] Furthermore, the dug-out part includes an insertion plate, a limiting block and a digging plate. The insertion plate is arranged at the end of the dug-out piece. A plurality of the digging plates are linearly arranged on one side of the insertion plate close to the axis of the cylinder along the sliding direction of the dug-out piece. One end of each digging plate is hinged to the insertion plate. One limiting block is provided on the insertion plate corresponding to each digging plate, and each limiting block is located on the side of the hinged end of the digging plate away from the cylinder.

[0013] Furthermore, an annular channel is circumferentially arranged inside the side wall of the cylinder. A plurality of liquid outlet branch channels are also arranged inside the side wall of the cylinder. One end of each liquid outlet branch channel is communicated with the annular channel and the other end is an outlet end. The outlet end extends to the end of the open end and is communicated with the outside; a lubricating mechanism is further included. The lubricating mechanism includes a liquid storage bin and a liquid guiding rubber tube. The liquid storage bin is installed outside the cylinder. The liquid guiding rubber tube circumferentially surrounds the driving disc and is arranged on the inner wall of the cylinder. One end of the liquid guiding rubber tube passes through the side wall of the cylinder and is communicated with the liquid storage bin, and the other end penetrates into the inside of the side wall of the cylinder and is communicated with the annular channel; a plurality of extrusion wheels are evenly distributed on the outer circumference of the driving disc. Each extrusion wheel is located on the circumferential path of the liquid guiding rubber tube and the distance between the extrusion wheel and the side wall of the cylinder is less than the diameter of the liquid guiding rubber tube.

[0014] Furthermore, the paths of each liquid outlet branch channel do not intersect with each other. The number of the liquid outlet branch channels is the same as the number of the dug-out pieces, and the position of each outlet end is located on one side of its corresponding sliding groove.

[0015] Furthermore, a clamping groove is opened at the end position of the outlet end. A blocking block is arranged at the end of each dug-out piece close to the outlet end. The blocking block can be clamped into the clamping groove to seal the outlet end.

[0016] Furthermore, a suction mechanism is further included. The suction mechanism includes a suction pipe, a suction pump and a feces storage bin. One end of the suction pipe is communicated with one side of the cylinder, and the other end is communicated with the feces storage bin. The suction pump is installed on the suction pipe.

[0017] Furthermore, a handle is further included. The handle is arranged on one side of the end of the cylinder away from the open end. A start switch is installed on the handle. The start switch is electrically connected to the motor.

[0018] As can be seen from the above technical solutions, a defecation device for the digestive department provided by the present invention surrounds the digging member around the circumference of the cylinder body and digs from all around the feces in the intestinal tract. It can not only dig out the dry and hard feces, but also the diameter of the feces becomes smaller after the outer circumference is dug, which is beneficial to reducing the intestinal resistance and accelerating the discharge of the remaining feces. By obliquely arranging the chute, the insertion resistance of the digging member is ingeniously reduced. By using the rotation of the driving disc in the cylinder body, the repeated digging operation of the digging member and the extrusion of the lubricating fluid are realized at the same time. By arranging the outlet end corresponding to each chute position, the directional output of the lubricating fluid to the digging position is realized. By combining the cooperation of the clamping groove and the plug block with the reciprocating movement mechanism of the digging member, the lubrication of only the digging member during the insertion process is realized, improving the utilization rate of the lubricating fluid and reducing the waste of the lubricating fluid.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manners.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] As Figure 1-7 shown, a defecation device for digestive department provided in this embodiment includes a cylinder body 1, a digging component 2 and a driving mechanism 3.

[0038] Please refer to Figure 1-Figure 6, one end of the cylinder body 1 is an open end 11 and the other end is a closed end. The open end 11 is used to extend into the patient's intestine. A plurality of inwardly extending sliding grooves 12 are circumferentially distributed on the inner wall of the open end 11. The sliding grooves 12 serve as the sliding channels for the digging member 2, so that the digging member 2 can dig from around the feces in the intestine. In this way, not only can the hard feces be dug out, but also the diameter of the feces becomes smaller after the outer circumferential side of the feces is dug, which is beneficial to reducing the intestinal resistance and accelerating the discharge of the remaining feces.

[0039] Preferably, the path of each sliding groove 12 is inclined based on the axis of the cylinder body 1, so that the digging member 2 can slide obliquely. In specific use, the digging member 2 can obliquely extend between the feces and the intestinal wall through the inclined sliding groove 12, which is gentler than the way of directly inserting, and at the same time can reduce the frictional resistance when the digging member 2 extends, making the digging member 2 extend more smoothly and reducing the discomfort of the patient.

[0040] Please continue to refer to Figure 1-Figure 6 , the digging member 2 is used to extend into the intestine to dig feces, and its whole is in a long strip shape. Preferably, the digging member 2 has a certain elasticity and can be slightly bent and deformed when subjected to external force, so as to prevent the digging member 2 from being too hard and causing injury to the intestinal wall. One digging member 2 is slidably arranged in each sliding groove 12. One end of the digging member 2 is connected to the extending end of the sliding groove 12 through an elastic member 21, and a driven part 22 is also arranged on one side of this end. The elastic member 21 can be selected as a spring. The elastic member 21 can provide an elastic force to make the digging member 2 lean towards the extending end of the sliding groove 12. The other end of the digging member 2 is located outside the open end 11 and is provided with a digging part 23.

[0041] As Figure 6As shown, in one embodiment, the scooping part 23 includes an insertion plate 231, a limiting block 232, and a scooping plate 233. The insertion plate 231 is disposed at the end of the scooping member 2 and its plate surface faces the axial direction of the cylinder 1. Specifically, the insertion plate 231 is flat so as to extend between the feces and the intestinal wall. On this basis, preferably, the insertion plate 231 also has a certain curvature so as to better fit the shape of the intestinal wall. A plurality of scooping plates 233 are linearly arranged on one side of the insertion plate 231 close to the axis of the cylinder 1 along the sliding direction of the scooping member 2, and one end of each scooping plate 233 is hinged to the insertion plate 231 so that the other end of the scooping plate 233 can move closer to or away from the plate surface of the insertion plate 231. It should be noted that the rotation center line of each scooping plate 233 should have an angle with the sliding path line of the scooping member 2 so that the scooping plate 233 can perform scooping operations according to the sliding of the scooping member 2. Preferably, the rotation center line of each scooping plate 233 is perpendicular to the sliding path line of the scooping member 2. A limiting block 232 is provided on the insertion plate 231 corresponding to each scooping plate 233. Each limiting block 232 is located on the side of the hinged end of the scooping plate 233 away from the cylinder 1 and is used to limit the rotation of the scooping plate 233 in the direction away from the cylinder 1. Specifically, the angle between the side of the limiting block 232 close to its corresponding scooping plate 233 and the plate surface of the insertion plate 231 should be less than 90°.

[0042] During specific use, when the scooping part 23 extends between the feces and the intestinal wall along with the sliding of the scooping member 2, each scooping plate 233 will rotate under the resistance of the feces and stick to the insertion plate 231 to reduce the resistance during insertion. When the scooping part 23 is withdrawn from between the feces and the intestinal wall along with the sliding of the scooping member 2, each scooping plate 233 will also rotate under the resistance during retraction and insert into the feces or scrape the feces out. The limiting block 232 can prevent the scooping plate 233 from rotating too much and thus prevent the scooping plate 233 from detaching from the feces.

[0043] Please refer to Figure 2-Figure 5 , the driving mechanism 3 is installed in the cylinder 1 and is drivingly connected to each driven part 22. The driving mechanism 3 can drive each scooping member 2 to slide outward along the chute 12.

[0044] As Figure 7As shown, in one embodiment, the driving mechanism 3 includes a motor 31 and a driving disk 32. The motor 31 is installed at the bottom of the inner cavity of the cylinder body 1 and the motor shaft faces the open end 11. The driving disk 32 is installed on the motor shaft, and an annular groove 321 is provided on the side away from the motor 31. The groove bottom path of the annular groove 321 is in an alternately undulating wavy shape, and the end of each driven part 22 abuts against the groove bottom of the annular groove 321. It should be noted that the cylinder body 1, the motor shaft of the motor 31, the driving disk 32, and the annular groove 321 are all coaxially arranged. During specific use, the driving disk 32 is driven by the motor 31 to rotate axially. Each driven part 22 always abuts against the groove bottom of the annular groove 321 under the pulling of the elastic member 21. The groove bottom of the wavy track of the annular groove 321 rotates continuously, driving each driven part 22 to repeatedly undulate along with the track of the annular groove 321, so as to realize the periodic extension and retraction movements of each digging member 2.

[0045] Preferably, rollers are provided at the ends of the driven parts 22 in contact with the annular groove 321, which is beneficial to reducing the friction between the driven parts 22 and the annular groove 321 when the driving disk 32 rotates.

[0046] In order to prevent excessive pressure on the patient's intestine caused by all the digging members 2 extending simultaneously, and at the same time to improve the dredging efficiency, in one embodiment, the heights at which each driven part 22 abuts against the groove bottom of the annular groove 321 at the same time are different, which is beneficial to the alternate digging of each digging member 2, improving the digging frequency while preventing all the digging members 2 from extending into the intestine together and causing excessive pressure on the intestine.

[0047] Please refer to Figure 1-Figure 6 , an annular channel 13 is circumferentially provided inside the side wall of the cylinder body 1, and a plurality of liquid outlet branch channels 14 are also provided inside the side wall of the cylinder body 1. One end of each liquid outlet branch channel 14 is communicated with the annular channel 13 and the other end is an outlet end 141, and the outlet end 141 extends to the end of the open end 11 and is communicated with the outside. It further includes a lubricating mechanism 4. The lubricating mechanism 4 includes a liquid storage bin 41 and a liquid guiding rubber tube 42. The liquid storage bin 41 is used for containing lubricating liquid. The liquid storage bin 41 is installed outside the cylinder body 1. The liquid guiding rubber tube 42 circumferentially surrounds the driving disk 32 and is arranged on the inner wall of the cylinder body 1. One end of the liquid guiding rubber tube 42 passes through the side wall of the cylinder body 1 and is communicated with the liquid storage bin 41, and the other end penetrates into the inside of the side wall of the cylinder body 1 and is communicated with the annular channel 13. A plurality of extrusion wheels 322 are evenly distributed on the outer circumference of the driving disk 32. Each extrusion wheel 322 is located on the circumferential path of the liquid guiding rubber tube 42 and the distance between the extrusion wheel 322 and the side wall of the cylinder body 1 is less than the diameter of the liquid guiding rubber tube 42. It should be noted that the rotation direction of the driving disk 32 should be consistent with the direction in which the lubricating liquid flows out through the liquid guiding rubber tube 42.

[0048] During specific use, the driving disk 32 is rotated by the motor 31. When the driving disk 32 rotates, the extrusion wheel 322 continuously slides and extrudes the liquid guide rubber tube 42, so as to form a negative pressure in the liquid guide rubber tube 42. Further, the lubricating liquid in the liquid storage chamber 41 flows out through the liquid guide rubber tube 42, and flows to the outlet end 141 through the annular channel 13 and each liquid outlet branch channel 14 to lubricate the patient's intestine.

[0049] In an embodiment, the paths of each liquid outlet branch channel 14 do not intersect, the number of the liquid outlet branch channels 14 is the same as the number of the digging parts 2, and the position of each outlet end 141 is located on one side of its corresponding sliding groove 12. It is beneficial to perform directional lubrication on the position where the digging part 2 extends, making the extension of the digging part 2 smoother.

[0050] Preferably, a clamping groove 142 is formed at the end position of the outlet end 141, and a blocking block 24 is arranged at the end of each digging part 2 close to the outlet end 141. The blocking block 24 can be clamped into the clamping groove 142 to seal the outlet end 141. When the driven part 22 corresponding to the digging part 2 is at the lowest position of the annular groove body 321, the blocking block 24 of the digging part 2 will be clamped into the clamping groove 142 to seal the outlet end 141. When the driven part 22 corresponding to the digging part 2 is lifted as the annular groove body 321 rotates, the blocking block 24 will release the seal of the outlet end 141. During specific use, the lubricating liquid can flow out from the outlet end 141 corresponding to the digging part 2 extending into the intestine, while the outlet end 141 where the retracted digging part 2 is located will be sealed by the blocking block 24, which is beneficial to provide lubrication for the digging position, improve the utilization rate of the lubricating liquid, and prevent waste of the lubricating liquid.

[0051] Please refer to Figure 1 , Figure 3 and Figure 5 In an embodiment, a suction mechanism 5 is further included. The suction mechanism 5 includes a suction pipe 51, a suction pump 52 and a feces storage bin 53. One end of the suction pipe 51 is communicated with one side of the cylinder body 1, and the other end is communicated with the feces storage bin 53. The suction pump 52 is installed on the suction pipe 51. The suction mechanism 5 can form a negative pressure in the inner cavity of the cylinder body 1, so that the scraped feces are sucked into the feces storage bin 53 for collection, and at the same time provide suction to assist the discharge of feces.

[0052] Please continue to refer to Figure 1 , Figure 3 and Figure 5 In an embodiment, a handle 6 is further included. The handle 6 is arranged on one side of the end of the cylinder body 1 away from the open end 11. A start switch 61 is installed on the handle 6. The start switch 61 is electrically connected to the motor 31. The handle 6 is convenient for the operator to hold, and the device can be quickly started through the start switch 61, which is beneficial to make the device more convenient to use.

[0053] A defecation device for the digestive department provided by the present invention, during specific use, the user inserts the open end 11 of the cylinder body 1 into the patient's intestine, holds the handle 6, and turns on the start switch 61. The motor 31 will drive the driving disk 32 to rotate, and the wavy bottom of the annular groove body 321 will also rotate accordingly. Under the combined action of the elastic force of the elastic member 21, each digging member 2 is driven to perform repeated extending and retracting movements. The digging member 2 digs the feces through the digging portion 23; while the driving disk 32 is rotating, the pressing wheel 322 continuously slides and presses the liquid guide rubber tube 42, so that the lubricating liquid is extruded to the outlet end 141 to lubricate the patient's intestine. And due to the cooperation of the card slot 142 and the plug 24, the lubricating liquid can only be extruded from the outlet end 141 when the digging member 2 is lifted by the annular groove body 321 and extends into the intestine; the suction mechanism 5 sucks the scraped feces into the feces storage bin 53 for collection, and at the same time provides suction to assist the feces to be discharged.

[0054] By arranging the digging members 2 to surround the cylinder body 1 circumferentially and digging from all around the feces in the intestine, not only can the dry and hard feces be dug out, but also the diameter of the feces becomes smaller after the outer circumferential side is dug, which is beneficial to reducing the intestinal resistance and accelerating the discharge of the remaining feces; by arranging the chute 12 obliquely, the insertion resistance of the digging member 2 is cleverly reduced; by using the rotation of the driving disk 32 in the cylinder body 1, the repeated digging operation of the digging member 2 and the extrusion of the lubricating liquid are realized at the same time. And by arranging the outlet end 141 corresponding to each chute 12 position, the directional output of the lubricating liquid to the digging position is realized. By combining the cooperation of the card slot 142 and the plug 24 with the back-and-forth movement mechanism of the digging member 2, the lubrication of only the digging member 2 during the extending process is realized, the utilization rate of the lubricating liquid is improved, and the waste of the lubricating liquid is reduced.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
