Description

Technical Field

[0001] This application relates to the field of enema technology, and more specifically, to an enema device for intestinal preparation in gastroenterology. Background Technology

[0002] Enemas are a treatment method that involves inserting a catheter through the rectum into the colon to infuse liquid, thereby relieving constipation and gas. They can stimulate intestinal peristalsis, soften and remove feces, and also have the effects of cooling, inducing labor, diluting intestinal toxins, and reducing absorption. Low-temperature solutions can help lower the temperature of patients with high fever. In addition, they can also be used to provide medication, nutrition, and water for other therapeutic purposes.

[0003] Patent document CN119280554A discloses an enema device for gastroenterology. This invention belongs to the field of enema technology, specifically referring to an enema device for gastroenterology, including a placement platform, a support, a direct-entry infusion mechanism, and a retractable extraction mechanism. The support is symmetrically arranged on the upper walls at both ends of the placement platform. The direct-entry infusion mechanism is located on the support, and the retractable extraction mechanism is located on the direct-entry infusion mechanism. The direct-entry infusion mechanism includes a direct-entry mechanism, an infusion mechanism, and a lubrication mechanism. The direct-entry mechanism is located on the upper wall of the support, the infusion mechanism is located on the upper wall of the placement platform, and the lubrication mechanism is located on the side wall of the direct-entry mechanism.

[0004] The aforementioned application document describes an enema performed by inserting a rounded head through the patient's anus into the intestines. However, once inserted into the patient's anus, it lacks support. Different patients have different body shapes and postures, and if some patients use different postures for the enema or if the patient moves around, it may slip out of the patient's anus. It is not convenient to stably insert it into the patient's anus while adapting to different body shapes or postures. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an intestinal preparation enema device for gastroenterology, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this application provides an enema device for gastroenterology, comprising a first base, an insertion assembly above the first base, the insertion assembly including a first electric push rod, a push seat fixedly connected to the right end of the first electric push rod, a slide rail slidably connected to the bottom of the push seat, the slide rail being fixedly connected to the top of the first electric push rod, a connector fixedly connected through and to the left side of the push seat, an insertion head fixedly installed at the left end of the connector, a swing seat fixedly connected to the bottom of the first electric push rod, a lifting block rotatably connected to the front of the swing seat, a second electric push rod rotatably connected to the back of the lifting block, the second electric push rod being hinged to the right side of the swing seat, a lifting assembly above the lifting block, an enema assembly on the right side of the insertion assembly, an expansion assembly on the outer surface of the insertion head, a lubrication assembly for increasing insertion lubrication below the insertion assembly, an adsorption assembly for increasing placement stability on the outer surface of the first base, the insertion assembly being inserted into the patient's anus, the insertion assembly itself being adjustable in pitch and extension to the left, facilitating insertion into the patient's anus after placement and adapting to different postures or intestinal structures.

[0007] Preferably, the lifting assembly includes a first support frame, which is fixedly connected to the top of the first base. A second support frame is fixedly connected to the top of the inner surface of the first support frame. The second support frame is slidably connected to the top of the lifting block. A motor is fixedly connected to the top of the inner surface of the first support frame. A screw is fixedly connected to the output end of the motor via a coupling. The screw is threaded through the top of the lifting block and rotatably connected to the bottom of the inner surface of the second support frame. The lifting assembly is used to drive the insertion assembly to move up and down, and can adjust the height of the insertion assembly to suit patients of different body shapes or postures.

[0008] Preferably, the enema assembly includes a second base, a support seat fixedly connected to the top of the second base, a third electric push rod fixedly connected to the inner surface of the support seat, an injection cylinder fixedly connected to the top of the support seat, a first piston rod slidably connected to the inner surface of the injection cylinder, a connecting piece fixedly connected to the right end of the first piston rod, the connecting piece being fixedly connected to the right end of the third electric push rod, a first one-way valve fixedly connected to the bottom of the injection cylinder, a suction tube fixedly connected to the lower end of the first one-way valve, a second one-way valve fixedly connected to the left side of the injection cylinder, and an injection tube connected between the second one-way valve and the connector. The enema assembly is used to push the enema liquid to the intestine of the person to be finally injected into the insertion component. Each time the enema assembly is withdrawn, it can automatically replenish the enema liquid and will not draw liquid from the patient's intestine.

[0009] Preferably, the expansion assembly includes an expansion airbag, which is fixedly connected to the outer surface of the insertion head. A first air chamber is fixedly connected to the back of the first support frame. A first flexible tube is connected between the first air chamber and the expansion airbag. A second piston rod is slidably connected to the inner surface of the first air chamber. A fourth electric push rod is fixedly connected to the upper end of the second piston rod. The fourth electric push rod is fixedly connected to the back of the first support frame. The expansion assembly can fill the gap between the insertion head and the patient's anus by expanding, which can prevent the insertion head from falling out of the patient's body where the anus is partially relaxed.

[0010] Preferably, the lubrication assembly includes a storage cylinder, which is fixedly connected to the bottom of the swing seat. A third piston rod is slidably connected to the inner surface of the storage cylinder, and the third piston rod is fixedly connected to the push seat. A third one-way valve is fixedly connected to the left side of the storage cylinder, and a fourth one-way valve is fixedly connected to the bottom of the storage cylinder. A small hole is opened on the outer surface of the insertion head. A second flexible hose is connected between the insertion head and the third one-way valve. The second flexible hose communicates with the small hole. The lubrication assembly can continuously release lubricating fluid from the head of the insertion head when the insertion head is inserted into the patient's intestine, thereby providing lubrication during insertion into the patient's intestine.

[0011] Preferably, the lubrication assembly further includes a storage tank, which is fixedly connected to the top of the injection cylinder. A third flexible hose is connected between the storage tank and the fourth one-way valve. With each insertion of the insertion head, the lubrication assembly causes the insertion head to release lubricant. With each retraction of the insertion head, the lubrication assembly automatically replenishes lubricant to facilitate the next insertion.

[0012] Preferably, the adsorption component includes a support plate, which is fixedly connected to the outer surface of the first support frame. A chamber is fixedly connected to the bottom of the support plate, and a suction cup is fixedly connected to the bottom of the chamber. A venting valve is fixedly connected to the right side of the chamber, and a connecting pipe is fixedly connected to the top of the chamber. The connecting pipe communicates with the inner surface of the chamber. The adsorption component can be adsorbed on the platform where the first base is placed. The higher the insertion component is raised by the lifting component, the stronger the suction force becomes, thereby making the first base more stable.

[0013] Preferably, the adsorption assembly further includes a second air chamber, which is fixedly connected to the front of the first support frame. A fourth flexible hose is connected between the second air chamber and the connecting pipe. A fourth piston rod is slidably connected to the inner surface of the second air chamber. The fourth piston rod is fixedly connected to the top of the lifting block. The lifting assembly lowers the insertion assembly to a low position to accommodate the patient's supine or leg-open supine position. At this time, the suction force of the adsorption assembly is minimal, so that slight movements of the patient's body can cause the insertion assembly to move slightly, preventing damage to the intestines caused by the fixed insertion assembly when the patient moves. The lifting assembly raises the insertion assembly to a high position to accommodate the patient's kneeling or supine position. At this time, the suction force of the adsorption assembly is maximum, preventing the insertion assembly from tipping over due to significant changes in the patient's posture.

[0014] The advantages of this application are: (1) This application uses an insertion component to insert into the patient's body so that the enema component can be used for enema. The insertion component can be adjusted by its own structure and lifting component to adapt to different patient body shapes or postures. At the same time, the expansion component increases the tightness after insertion, which helps to ensure that the device is stably inserted into the anus of patients with different body shapes or postures.

[0015] (2) This application uses a lubrication component to keep the patient’s anus and intestines lubricated when the insertion component is inserted into the patient’s anus. When the insertion component is inserted into the patient’s anus, it will drive the lubrication component to continuously spray out lubricating liquid, which has the function of protecting the patient’s intestines and preventing the patient’s intestines from being damaged.

[0016] (3) This application sets up an adsorption component to ensure stability when the insertion component is placed. When the lifting component adjusts the insertion component to a higher position, it will also drive the adsorption component to strengthen the adsorption force, thereby strengthening the stability of placement. It has the function of facilitating stable placement and can prevent the insertion component from falling out of the anus to a certain extent due to the patient moving around.

[0025] Example 1, see Figures 1-8This embodiment provides an enema device for gastroenterology, including a first base 1. An insertion component 2 is disposed on the top of the first base 1. The insertion component 2 is used for insertion into the patient's anus. The insertion component 2 itself can be adjusted for pitch and can extend to the left, making it easy to insert into the patient's anus after placement and adapting to different postures or intestinal structures. The insertion component 2 includes a first electric push rod 201, with the right side of the first electric push rod 201 being the output end. A push seat 202 is fixedly connected to the right end of the first electric push rod 201. The push seat 202 is lightning-shaped, and a slide rail 208 is slidably connected to the bottom of the push seat 202. The slide rail 208 has a trapezoidal cross-section, and a dovetail is provided at the bottom of the push seat 202 to match the slide rail 208. The groove and slide rail 208 are fixedly connected to the top of the first electric push rod 201. A connector 203 is fixedly connected through the left side of the push seat 202. An insertion head 204 is fixedly installed on the left end of the connector 203. The insertion head 204 is used to insert into the patient's anus. The left end of the insertion head 204 is provided with a round head protruding outward. The outer surface of the insertion head 204 is provided with a silicone layer, and the inner surface is made of plastic. A swing seat 205 is fixedly connected to the bottom of the first electric push rod 201. The swing seat 205 is L-shaped. A lifting block 206 is rotatably connected to the front of the swing seat 205. A second electric push rod 207 is rotatably connected to the back of the lifting block 206. The second electric push rod 207 is hinged to the right side of the swing seat 205. The output end of the second electric push rod 207 is connected to the swing seat 205. Hinged between 05, a lifting component 3 is provided above the lifting block 206. The lifting component 3 is used to drive the insertion component 2 to rise and fall, and can adjust the height of the insertion component 2 to adapt to patients with different body shapes or postures. The lifting component 3 includes a first support frame 301, which is U-shaped and fixedly connected to the top of the first base 1. A second support frame 302, which is U-shaped, is fixedly connected to the top of the inner surface of the first support frame 301 and is slidably connected to the top of the lifting block 206. A motor 303 is fixedly connected to the top of the inner surface of the first support frame 301. The output end of the motor 303 is fixedly connected to a screw 304 through a coupling. The screw 304 is connected to the lifting block 206. The top thread of the 06 is through, and the screw 304 is rotatably connected to the bottom of the inner surface of the second support frame 302. The rotation of the screw 304 can drive the lifting block 206 to rise and fall on the second support frame 302. An enema component 4 is provided on the right side of the insertion component 2. The enema component 4 is used to push the enema liquid to the insertion component 2 and finally inject it into the human intestine. Each time the enema component 4 is withdrawn, it can automatically replenish the enema liquid and will not draw the liquid in the patient's intestines to facilitate the next insertion. The enema component 4 includes a second base 401, and a support seat 402 is fixedly connected to the top of the second base 401. The support seat 402 is C-shaped, and a third electric push rod 403 is fixedly connected to the inner surface of the support seat 402. The right end of the third electric push rod 403 is the output end.An injection cylinder 404 is fixedly connected to the top of the support base 402. The injection cylinder 404 contains enema fluid. A first piston rod 405 is slidably connected to the inner surface of the injection cylinder 404. A connecting piece 406 is fixedly connected to the right end of the first piston rod 405. The connecting piece 406 is fixedly connected to the right end of a third electric push rod 403. The third electric push rod 403 can drive the connecting piece 406 to make the first piston rod 405 slide on the inner surface of the injection cylinder 404, thereby pushing the enema fluid in the injection cylinder 404 into the patient's body. A first one-way valve 407 is fixedly connected to the bottom of the injection cylinder 404. The first one-way valve 407 restricts the enema fluid from entering the injection cylinder 404 only from the outside, preventing the enema fluid in the injection cylinder 404 from flowing outwards through the first one-way valve 407. The first one-way valve 407 has a suction tube 408 fixedly connected to its lower end. The suction tube 408 is used to connect to an external container for storing enema fluid, so as to add new enema fluid to the injection cylinder 404. A second one-way valve 409 is fixedly connected to the left side of the injection cylinder 404. The second one-way valve 409 is used to restrict the flow of enema fluid from the injection cylinder 404 to the outside. External enema fluid will not flow into the injection cylinder 404 through the first one-way valve 407. An injection tube 410 is connected between the second one-way valve 409 and the connector 203. Both the injection tube 410 and the suction tube 408 are flexible tubes. An expansion component 5 is provided on the outer surface of the insertion head 204. The expansion component 5 can fill the gap between the insertion head 204 and the patient's anus by expansion, which can prevent... The insertion head 204 is prevented from dislodging from the patient's body due to partial anal laxity. The expansion assembly 5 includes an expansion bladder 501, which is thicker at both ends and thinner in the middle, and is used to lock into the patient's anus. The expansion bladder 501 is fixedly connected to the outer surface of the insertion head 204. A first air chamber 502 is fixedly connected to the back of the first support frame 301. A first flexible tube 503 connects the first air chamber 502 and the expansion bladder 501. The first air chamber 502 and the expansion bladder 501 are connected through the first flexible tube 503. A second piston rod 504 is slidably connected to the inner surface of the first air chamber 502. A fourth electric push rod 505 is fixedly connected to the upper end of the second piston rod 504. The lower end of the fourth electric push rod 505 is the output end. The second piston rod 504 and the fourth electric push rod... The output terminals of 505 are connected. The fourth electric push rod 505 is fixedly connected to the back of the first support frame 301. A lubrication component 6 for increasing insertion lubrication is installed below the insertion component 2. The lubrication component 6 can continuously release lubricating fluid from the head of the insertion head 204 when the insertion head 204 is inserted into the patient's intestine, thereby playing a lubricating role during insertion. With each insertion of the insertion head 204, the lubrication component 6 will cause the insertion head 204 to release lubricating fluid. With each retraction of the insertion head 204, the lubrication component 6 will automatically replenish the lubricating fluid to facilitate the next insertion. An adsorption component 7 for increasing placement stability is installed on the outer surface of the first base 1. The adsorption component 7 can adhere to the platform where the first base 1 is placed.The higher the insertion component 2 is raised by the lifting assembly 3, the stronger the suction, thus making the first base 1 more stable. Lowering the insertion component 2 by the lifting assembly 3 accommodates the patient's supine or leg-open lying position. At this position, the suction of the adsorption assembly 7 is at its minimum, allowing slight movements of the patient's body to follow the insertion component 2 with small movements, preventing damage to the intestines caused by the fixed insertion component 2 during patient movement. Raising the insertion component 2 by the lifting assembly 3 to a high position accommodates the patient's kneeling or prone position. At this position, the suction of the adsorption assembly 7 is at its maximum, preventing the insertion component 2 from tipping over due to significant changes in the patient's posture.

[0026] In practical use, the patient first lies face down on the medical platform in a suitable position. Then, the first base 1 is placed between the patient's legs near the anus. The motor 303 is then activated to rotate the screw 304. The rotation of the screw 304 causes the lifting block 206 to rise and fall on the second support frame 302, thereby causing the swing seat 205 and its connected structures to raise and lower the insertion head 204 to a suitable height. The second electric push rod 207 is then activated to push or pull the swing seat 205 to the left or right on the lifting block 206, thus adjusting the pitch angle of the insertion head 204 to align with the patient's anus. Finally, the first electric push rod 201 is activated to move the push seat 202 and the connecting head 203 to the left, thereby moving the insertion head 204 to the left and inserting it into the patient's anus. The enema is performed until the inflatable balloon 501 on the insertion head 204 is positioned around the patient's anus. At this point, the fourth electric push rod 505 is activated to extend it. The fourth electric push rod 505 pushes the second piston rod 504 to slide downwards on the inner surface of the first air chamber 502, thereby pushing the gas inside it through the first hose 503 into the inflatable balloon 501, causing the inflatable balloon 501 to expand and seal the gap between the insertion head 204 and the patient's anus. At this point, the third electric push rod 403 is activated to contract it. The third electric push rod 403 pulls the connecting piece 406 to slide the first piston rod 405 to the left within the injection cylinder 404, thereby pushing the enema liquid in the injection cylinder 404 through the injection tube 410 and the connecting head 203 into the insertion head 204 and spraying it out from the insertion head 204, thus performing an enema on the patient.

[0027] Example 2, see Figures 1-8The lubrication assembly 6 includes a storage cylinder 601 containing lubricating fluid. The storage cylinder 601 is fixedly connected to the bottom of the swing seat 205. A third piston rod 602 is slidably connected to the inner surface of the storage cylinder 601 and fixedly connected to the push seat 202. A third one-way valve 603 is fixedly connected to the left side of the storage cylinder 601 to prevent external liquid from entering the storage cylinder 601. A fourth one-way valve 604 is fixedly connected to the bottom of the storage cylinder 601 to prevent liquid in the storage cylinder 601 from entering the storage cylinder 601. The one-way valve 604 flows to the outside. The outer surface of the insert head 204 has a small hole 605. A second hose 606 is connected between the insert head 204 and the third one-way valve 603. The second hose 606 is connected to the small hole 605. A channel is provided inside the insert head 204 for the second hose 606 to communicate with the small hole 605. The lubrication assembly 6 also includes a storage tank 607. The storage tank 607 is provided with a threaded cap. The storage tank 607 is filled with lubricating fluid. The storage tank 607 is fixedly connected to the top of the injection cylinder 404. A third hose 608 is connected between the storage tank 607 and the fourth one-way valve 604.

[0028] In practical use, when the first electric push rod 201 moves the push seat 202 and connector 203 to the left, causing the insertion head 204 to be inserted into the patient's anus, the leftward movement of the push seat 202 also causes the third piston rod 602 to slide to the left within the storage cylinder 601. The third piston rod 602 pushes the lubricating fluid in the storage cylinder 601 to seep out through the third one-way valve 603, the second hose 606, and the channel within the insertion head 204 from the small hole 605. This ensures continuous lubrication during the insertion of the insertion head 204 into the intestine. When the first electric push rod 201 moves the push seat 202 and connector 203 to the right, causing the insertion head 204 to be withdrawn from the patient's anus, the rightward sliding of the third piston rod 602 within the storage cylinder 601 causes the third hose 608 to draw out the lubricating fluid stored in the storage tank 607 for replenishment, so that no additional lubricating fluid needs to be added for the next insertion.

[0029] Example 3, see Figures 1-8The adsorption component 7 includes a support plate 701, which is fixedly connected to the outer surface of the first support frame 301. A reinforcing rib is provided between the support plate 701 and the first support frame 301. A chamber 702 is fixedly connected to the bottom of the support plate 701, and a suction cup 703 is fixedly connected to the bottom of the chamber 702. A venting valve 704 is fixedly connected to the right side of the chamber 702. The venting valve 704 can be manually opened or closed for connecting or closing the chamber 702 to the outside. A connecting pipe 705 is fixedly connected to the top of the chamber 702, and the connecting pipe 705 communicates with the inner surface of the chamber 702. The adsorption assembly 7 includes two support plates 701, chambers 702, suction cups 703, venting valves 704, and connecting pipes 705, which are symmetrically arranged front and rear. The adsorption assembly 7 also includes a second air chamber 706, which is fixedly connected to the front of the first support frame 301. A fourth flexible hose 707 is connected between the second air chamber 706 and the connecting pipe 705. A fourth piston rod 708 is slidably connected to the inner surface of the second air chamber 706 and is fixedly connected to the top of the lifting block 206. There are two second air chambers 706, fourth flexible hoses 707, and fourth piston rods 708.

[0030] In practical use, the suction cup 703 will also contact the placement surface when the first base 1 is placed. When the lifting block 206 rises on the second support frame 302, the rise of the lifting block 206 will drive the fourth piston rod 708 to rise in the second air chamber 706, thereby drawing air out of the second air chamber 706. This causes the second air chamber 706 to draw air out of the chamber body 702 through the fourth hose 707, causing the suction cup 703 to generate negative pressure and stick to the placement surface, thereby enhancing the stability of the placement and preventing the center of gravity from becoming unstable due to the lifting block 206 and its auxiliary parts rising too high, which could cause the entire device to tip over when the patient moves around.

[0031] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
