Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to an enema device. Background Art

[0002] Enema is a method of injecting liquid into the intestine through the anus for therapeutic or cleansing purposes. The following are the general steps of enema: 1. Prepare enema fluid: Usually, normal saline, soap water, etc. are used. Select a suitable enema fluid according to specific needs and doctor's advice. 2. Patient preparation: Assist the patient to take a left lateral position, with the legs flexed, and expose the buttocks. 3. Lubricate the anal tube: Apply lubricant to the front end of the anal tube to reduce friction and discomfort during insertion. 4. Insert the anal tube: Slowly insert the anal tube into the anus about 7 - 10 cm. Observe the patient's reaction during the insertion process. If discomfort or pain occurs, stop immediately. 5. Infuse enema fluid: Fix the anal tube and slowly pour the enema fluid into the enema bag, allowing the enema fluid to flow into the intestine naturally. The infusion speed should not be too fast, generally 60 - 80 drops per minute. 6. Observe the reaction: During the enema process, closely observe the patient's complexion, pulse, breathing, etc. If there is any abnormality, stop the enema immediately and take corresponding measures. 7. Withdraw the anal tube: When the enema fluid infusion is completed, clamp the end of the anal tube with a hemostat and gently withdraw the anal tube. Let the patient lie flat and rest for a while to allow the enema fluid to fully play its role.

[0003] The elderly are one of the main groups for enema. The levator ani muscle of the elderly is more relaxed than that of the young, which easily leads to leakage during enema, making it difficult for the enema fluid to fully play its role, not only affecting the enema effect but also causing pollution of clothes and bedding. Summary of the Invention

[0004] Aiming at the problem that the elderly are prone to leakage during enema in the prior art, the present invention provides an enema device.

[0005] The technical solution adopted by the present invention is as follows:

[0006] An enema device includes an enema tube and a liquid storage container filled with enema fluid. One end of the enema tube is connected to the liquid storage container, and the other end is provided with a leak-proof mechanism;

[0007] The leak-proof mechanism includes a primary leak-proof structure. The primary leak-proof structure includes an annular bladder provided on the enema tube. There is liquid in the annular bladder, and a liquid inlet and outlet are also provided on the annular bladder. During the process of inserting the enema tube into the human body, it is determined whether to add or drain liquid and the amount of liquid to be added or drained according to the flow of the liquid in the annular bladder;

[0008] The leak prevention mechanism further includes a secondary leak prevention structure, which includes an abutting member disposed on the enema tube. The abutting member includes an abutting portion and a connecting portion connected to each other. The connecting portion is connected to the enema tube. The abutting portion is in a funnel shape, and the abutting portion and the connecting portion together form a receiving space. The abutting portion is sleeved on the annular sac, and one end of the annular sac is located within the receiving space. The annular sac is made of an elastic material, and the elasticity of the part of the annular sac within the receiving space is greater than that of other parts.

[0009] After adopting this technical solution, the present invention provides a two-stage leak prevention structure. The primary leak prevention structure wraps around one end of the enema tube inserted into the human body. There is liquid in the annular sac. During the process of inserting the enema tube into the human body, if the user's levator ani muscle has sufficient strength, it will block the flowing liquid in the annular sac outside the anus. At this time, since the elasticity of the part of the annular sac within the receiving space is greater than that of other parts, the liquid in the annular sac flows towards one end within the receiving space of the secondary leak prevention mechanism, causing the end of the annular sac within the receiving space to expand, thereby exerting a thrust on the abutting portion of the secondary leak prevention structure, making the abutting portion fully abut against the anus, thus preventing leakage during enema. If during the process of inserting the enema tube into the human body, the operator finds that the end of the annular sac within the receiving space does not expand significantly, it indicates that the user's levator ani muscle lacks strength or is relatively relaxed. At this time, liquid can be added to the annular sac to make the end of the annular sac within the receiving space expand. Since the volume of the receiving space is limited, when the receiving space expands large enough, the rest also expands with the addition of liquid, causing the part of the annular sac in contact with the anus to expand, so as to fully contact the anus and prevent liquid from flowing out. During the process of adding liquid, the operator can gently twitch the enema tube. If it is found that the liquid flows significantly, it means that the annular sac has fully contacted the anus, and then the addition of liquid can be stopped, and normal enema operation can be carried out. The present invention effectively reduces the risk of leakage during enema by providing a two-stage leak prevention structure to block the anus, and is suitable for patients with different anus sizes, which can effectively ensure the enema effect.

[0010] Preferably, the annular sac is sleeved on the enema tube, and one end of the annular sac close to the end inserted into the anus is fixedly connected to the enema tube, and the other end of the annular sac is detachably connected to the enema tube.

[0011] After adopting this technical solution, one end of the annular sac close to the end of the enema tube is fixedly connected to the enema tube, and the other end is detachably connected. When the enema is finished, the detachably connected end of the annular sac and the enema tube can be disassembled. The liquid in the annular sac flows downward under the action of gravity, causing the annular sac to turn over, so as to turn the end inserted into the human body to the inside, avoiding discomfort to the operator.

[0012] Preferably, the connecting part is threadedly connected to the enema tube, and one end of the annular sac is disposed at the threaded connection between the connecting part and the enema tube.

[0013] After adopting this technical solution, the detachable connection between one end of the annular sac and the enema tube is achieved by pressing one end of the annular sac at the threaded connection between the connecting part and the enema tube.

[0014] Preferably, it further includes a heating mechanism that can be sleeved on the liquid storage container. The heating mechanism includes a housing. An inner surface of the housing is provided with a water bag. A heating element and a temperature detection element are provided between the housing and the water bag. A temperature control component electrically connected to the heating element and the temperature detection element is provided on the housing.

[0015] After adopting this technical solution, the elderly are more sensitive to enema. In order to reduce their discomfort, the present invention also provides a heating mechanism, and this heating mechanism is of the water bag type. After the enema liquid in the liquid storage container is preheated, a part of the liquid in the water bag can be drained into the annular sac, so that the liquid in the annular sac is also close to the human body temperature, reducing the probability of causing discomfort to the patient when the annular sac contacts the human body.

[0016] Preferably, a liquid discharge tube and a liquid adding tube are provided on the water bag. The liquid discharge tube is connected to a two-way micro pump provided on the housing. The two-way micro pump is detachably connected to the liquid inlet and outlet of the annular sac.

[0017] After adopting this technical solution, after the enema is finished, a part of the liquid in the annular sac can be sucked back into the water bag, making the volume of the annular sac smaller and easier to take out, and at the same time saving water resources.

[0018] Preferably, the housing is made of cloth, soft silicone or soft rubber, and one end of the housing is detachably connected to the other end. A hanging hole is provided on the housing.

[0019] Preferably, the abutting part is made of soft silicone or soft rubber, and the connecting part is made of rigid transparent plastic.

[0020] After adopting this technical solution, the abutting part is a flexible material with a certain supporting strength, making it have a certain deformation ability and better fit with the anus, and at the same time having sufficient resistance.

[0021] Preferably, a liquid absorbing member is provided on a side of the abutting part that contacts the anus. The liquid absorbing member includes a containing bag fixedly connected to the abutting part. Absorbent swelling particles are contained in the containing bag. A liquid passing hole is provided on the containing bag, and the size of the liquid passing hole is smaller than the initial size of the absorbent swelling particles.

[0022] Preferably, a guiding ring is provided at the junction of one end of the enema tube inserted into the human body and the annular sac. The guiding ring is of a funnel-shaped structure.

[0023] After adopting this technical solution, the anus is pre-expanded through the guiding ring, facilitating its full contact with the annular sac.

[0024] Preferably, a first connecting ring that can be sleeved on the enema tube is connected to the connecting portion. A second connecting ring is rotatably arranged on the enema tube. The first connecting ring and the second connecting ring are threadedly connected. The abutting portion is made of an elastic material, and a positioning ring is arranged at the opening of the abutting portion for passing through the enema tube. The positioning ring makes the opening of the abutting portion in a stretched state; at the junction of the end of the enema tube inserted into the human body and the annular sac, a guiding ring is arranged. The guiding ring is of a funnel-shaped structure and includes a rigid portion and a soft portion wrapped on the rigid portion. The width of the rigid portion is greater than the inner diameter of the positioning ring and less than the outer diameter of the positioning ring. The width of the rigid portion is also less than the inner diameter of the first connecting ring.

[0025] Furthermore, an adhesive tape is also arranged on the connecting portion, and a dust-proof sticker is arranged on the adhesive tape.

[0026] In summary, due to adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0027] The present invention is provided with a two-stage anti-leakage structure. The first-stage anti-leakage structure is wrapped around the end of the enema tube inserted into the human body. There is liquid in the annular sac. During the process of inserting the enema tube into the human body, if the user's levator ani muscle has sufficient strength, it will block the liquid with fluidity in the annular sac outside the anus. At this time, since the elasticity of the part of the annular sac located in the accommodation space is greater than other parts, the liquid in the annular sac flows towards the end in the accommodation space of the secondary anti-leakage mechanism and makes the end of the annular sac located in the accommodation space expand, thereby exerting a thrust on the abutting portion of the secondary anti-leakage structure, making the abutting portion fully abut against the anus, thus preventing leakage during enema. If during the process of inserting the enema tube into the human body, the operator finds that the end of the annular sac located in the accommodation space does not expand significantly, it means that the user's levator ani muscle has insufficient strength or is relatively relaxed. At this time, liquid can be added to the annular sac to make the end of the annular sac located in the accommodation space expand. Since the volume of the accommodation space is limited, when the accommodation space expands large enough, the rest also expands with the addition of liquid, making the part of the annular sac in contact with the anus expand, so as to fully contact the anus and avoid liquid outflow. During the process of adding liquid, the operator can slightly twitch the enema tube. If it is found that the liquid flows significantly, it means that the annular sac and the anus have fully contacted, and then the addition of liquid can be stopped and normal enema operation can be carried out. The present invention effectively reduces the risk of leakage during enema by setting a two-stage anti-leakage structure to block the anus, and is suitable for patients with different anus sizes, and can effectively ensure the enema effect.

[0028] The elderly are more sensitive to enema. In order to reduce their discomfort, the present invention also provides a heating mechanism, and the heating mechanism is a water bag type. After the enema liquid in the liquid storage container is preheated, a part of the liquid in the water bag can be discharged into the annular bag, so that the liquid in the annular bag is also close to the human body temperature, reducing the probability of causing discomfort to the patient when the annular bag contacts the human body.

It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of this application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be construed as indicating or implying relative importance.

[0042] As Figures 1-6 shown, an enema device includes an enema tube 3 and a liquid storage container 4 filled with enema liquid. In this embodiment, as Figure 1 shown ( Figure 1 the truncated part in the figure indicates that the length of the enema tube 3 is indefinite), the liquid storage container 4 is an enema bag, and in other embodiments, it can also be a bottled enema liquid, etc. Its structure is the same as that of the prior art, so it will not be elaborated here; one end of the enema tube 3 is connected to the liquid storage container 4, and the other end is provided with a leak-proof mechanism;

[0043] As Figure 2As shown, the leak-proof mechanism includes a primary leak-proof structure. The primary leak-proof structure includes an annular pouch 8 provided on the enema tube 3. There is liquid inside the annular pouch 8. In this embodiment, the liquid is water, and in other embodiments, it can also be other liquids as long as they have good fluidity. There is also a liquid inlet / outlet provided on the annular pouch 8. A pipe is provided at the liquid inlet / outlet, and a liquid stop valve is provided on the pipe. The pipe can be opened or closed through the liquid stop valve (not shown in the figure). Through the pipe, liquid can be added to or discharged from the annular pouch 8. In this embodiment, the annular pouch 8 is made of hospital-grade silicone material, which is elastic and can expand and contract. The end located inside the accommodating space has greater elasticity, that is, it is more relaxed and easier to be inflated. The length of the annular pouch 8 is approximately 10 - 12 cm to meet the requirement of the insertion depth of the enema tube 3. The end of the annular pouch 8 is about 0 - 2 cm away from the end of the enema tube 3. In this embodiment, it is about 0.5 cm. During the process of inserting the enema tube 3 into the human body, it is determined whether to add or discharge liquid and the amount of liquid to be added or discharged according to the flow of the liquid inside the annular pouch 8.

[0044] Specifically, the usage method and function of the primary leak-proof structure are as follows: As Figures 2-5 shown, the operator sets the initial amount of liquid added to the annular pouch 8 according to the size of the human anus (the initial added amount can be set to a suitable initial added amount for different age groups according to age, etc.), so that the size of the annular pouch 8 after adding the initial added amount of liquid meets the anus size of most people. After the liquid is added, the enema tube 3 is inserted into the anus. During the insertion process, the operator not only needs to observe the patient's state but also needs to pay attention to the flow of the liquid inside the annular pouch 8. If there is obvious flow of the liquid inside the annular pouch 8, causing the part of the annular pouch 8 located inside the accommodating space to expand (from Figure 3 to Figure 4 ), it means that the levator ani muscle of the patient has sufficient strength and the annular pouch 8 fits tightly with the anus, achieving the initial leak-proof effect. If there is no obvious flow of the liquid inside the annular pouch 8 and the end of the annular pouch 8 located inside the accommodating space does not expand significantly, it means that the levator ani muscle of the user has insufficient strength or is relatively relaxed. At this time, liquid can be added to the annular pouch 8 to make the end of the annular pouch 8 located inside the accommodating space expand. Since the volume of the accommodating space is limited, when the accommodating space expands large enough, the rest also expands with the addition of liquid, causing the part of the annular pouch 8 in contact with the anus to expand, so as to fully contact the anus. During the process of adding liquid, the operator can gently twitch the enema tube 3. If it is found that the liquid has obvious flow, it means that the annular pouch 8 has fully contacted the anus, and then the addition of liquid can be stopped, thereby achieving the initial leak-proof effect.

[0045] The leak-proof mechanism further includes a secondary leak-proof structure. The secondary leak-proof structure includes a contact member provided on the enema tube 3. The contact member includes a contact portion 12 and a connection portion 13 that are connected to each other. The contact portion 12 can be made of soft silicone or soft rubber. In this embodiment, it is made of medical soft silicone, and its thickness is about 0.5 - 1 cm to ensure that it has sufficient supporting force and deformation ability; the connection portion 13 is made of rigid transparent plastic to facilitate observing whether the annular bladder 8 expands. An opening is also provided on the connection portion 13 to cooperate with the pipe at the liquid inlet and outlet of the annular bladder 8. The size of the opening should be larger than the size of the pipe at the liquid inlet and outlet to facilitate the passage of the pipe at the liquid inlet and outlet; the connection portion 13 is connected to the enema tube 3. The contact portion 12 is in a circular funnel shape, and the contact portion 12 and the connection portion 13 together form an accommodation space. The large head end of the contact portion 12 is connected to the connection portion 13, and its small head end is sleeved on the annular bladder 8. The diameter of the small head end is larger than the diameter of the annular bladder 8 after expansion, so that the liquid in the annular bladder 8 can enter the accommodation space; a liquid absorbing member is provided on the side of the contact portion 12 in contact with the anus. The liquid absorbing member can absorb the leaked liquid to avoid soiling the beddings and clothes.

[0046] The specific usage method and function of the secondary leak-proof structure are as follows: The position of the contact portion 12 is at 7 - 10 cm of the enema tube 3. When the anus reaches the contact portion 12, it means that the enema tube 3 has been inserted 7 - 10 cm, and then the insertion can be stopped, which serves as a mark for the end point of insertion; after the insertion is completed, the contact portion 12 abuts against the anus. When the annular bladder 8 expands in the accommodation space, a contact force will be generated on the contact portion 12, causing the contact portion 12 to deform slightly, making the contact portion 12 fit more closely to the anus and reducing the gap. The liquid absorbing member on the contact portion 12 can absorb a small amount of liquid that may leak out, thus achieving the effect of secondary leak-proof.

[0047] By the cooperation of the primary leak-proof structure and the secondary leak-proof structure to block the anus, the risk of leakage during enema is effectively reduced, and it is suitable for patients with different anus sizes, which can effectively ensure the enema effect.

[0048] In one embodiment, the annular pouch 8 is sleeved on the enema tube 3, and one end of the annular pouch 8 close to the end where the enema tube 3 is inserted into the anus is fixedly connected to the enema tube 3, and the other end of the annular pouch 8 is detachably connected to the enema tube 3. Specifically, the connecting portion 13 and the enema tube 3 can be in a threaded connection, and one end of the annular pouch 8 is arranged at the threaded connection of the connecting portion 13 and the enema tube 3. The detachable connection between one end of the annular pouch 8 and the enema tube 3 is achieved by pressing one end of the annular pouch 8 at the threaded connection of the connecting portion 13 and the enema tube 3. The remaining part of the annular pouch 8 contacts but is not connected to the outer wall of the enema tube 3; when the enema tube 3 needs to be withdrawn after the enema, the connecting portion 13 can be rotated first to separate one end of the annular pouch 8 from the enema tube 3, and then the enema tube 3 can be withdrawn. At this time, since the annular pouch 8 is in close contact with the anus and the intestine, the frictional force is large. Therefore, the enema tube 3 will be withdrawn from the human body first, and then as the enema tube 3 continues to be withdrawn, the end of the annular pouch 8 fixedly connected to the enema tube 3 will be withdrawn as the annular pouch 8 is withdrawn, so as to form a flip of the annular pouch 8 in the human body. In this way, when the annular pouch 8 is completely withdrawn, the soiled side is located inside the annular pouch 8 and cannot be seen by the operator, reducing their discomfort; in other embodiments, the enema tube 3 can also be withdrawn first and then the connecting portion 13 can be rotated to separate one end of the annular pouch 8 from the enema tube 3, and the end with the annular pouch 8 is facing downwards. The liquid in the annular pouch 8 flows downward under the action of gravity, driving the annular pouch 8 to complete the flip (as Figure 7 and Figure 8 shown), so as to flip the end inserted into the human body to the inside and avoid causing discomfort to the operator.

[0049] In one embodiment, as Figure 6As shown, it further includes a heating mechanism that can be sleeved on the liquid storage container 4. The heating mechanism includes a housing 1, and an aqueous bag 2 is provided on the inner surface of the housing 1. A heating element 15 and a temperature detection element are provided between the housing 1 and the aqueous bag 2. In this embodiment, the heating element 15 is an electric heating wire, and the temperature detection element is a temperature sensor. A temperature control component electrically connected to the heating element 15 and the temperature detection element is provided on the housing 1. The temperature control component includes a microcontroller connected to the heating element 15 and the temperature sensor, and further includes a regulation panel provided on the outer surface of the housing 3. The regulation panel is electrically connected to the microcontroller. Through the cooperation of the heating element 15, the temperature detection element, and the temperature control component, the temperature of the liquid in the liquid storage container 4 can be regulated. For example, its temperature can be controlled at about 40 °C. The temperature sensor is arranged on the contact surface of the aqueous bag 2 with the liquid storage container 4 to detect the temperature near the liquid storage container 4. When the detected temperature is about 37 °C, the heating element 15 can be controlled to turn off, and the aqueous bag 2 is used for heat preservation. In this embodiment, the heating element 15 can be an electrothermal film. The electrothermal film is flexible and can adapt to the bending of the heating mechanism. The heating element 15 is arranged between the aqueous bag 2 and the housing 1, and the heating element 15, the aqueous bag 2, and the housing 1 are an integral body. After the heating element 15 is started, it generates heat, and the heat is transferred to the liquid in the aqueous bag 2 through heat conduction, so that the temperature of the liquid in the aqueous bag 2 rises. When the aqueous bag 2 wraps around the liquid storage container 4, the heat can be transferred to the enema solution, thereby realizing the heating of the enema solution, which can greatly reduce the discomfort of the patient during enema. Further, in order to improve convenience, the power of the heating element 15 can be set to be relatively large, so that the liquid in the aqueous bag 2 can be quickly heated.

[0050] In one embodiment, a drain pipe and a filling pipe 5 are provided on the aqueous bag 2. The drain pipe is connected to a two-way micro pump 7 provided on the housing 1. The two-way micro pump 7 is detachably connected to the liquid inlet and outlet of the annular bag 8. After enema is completed, a part of the liquid in the annular bag 8 can be sucked back into the aqueous bag 2, so that the volume of the annular bag 8 becomes smaller and it is convenient to take out, and at the same time, water resources can be saved. After the enema solution in the liquid storage container 4 is preheated, a part of the liquid in the aqueous bag 2 can be drained into the annular bag 8, so that the liquid in the annular bag 8 is also close to the human body temperature, reducing the probability of discomfort caused to the patient when the annular bag 8 contacts the human body.

[0051] In one embodiment, the housing 1 is made of cloth, soft silicone or soft rubber. In this embodiment, it is made of high-temperature resistant soft silicone. The inner surface of one end of the housing 1 is provided with a hook surface magic tape 6, and the outer surface of the other end is provided with a mating loop surface magic tape. The detachable connection is achieved through the cooperation of the hook surface magic tape 6 and the loop surface magic tape. A hanging hole 9 is provided on the housing 1, and through the hanging hole 9, the heating mechanism can be hung on the infusion stand, so as to sleuth it on the liquid storage container 4 that is also hung on the infusion stand. The heating mechanism with this structure can meet the heating requirements of liquid storage containers 4 of various sizes and shapes, and is more convenient to use.

[0052] In one embodiment, as Figure 6 shown, in order to facilitate viewing the remaining amount of liquid in the liquid storage container 4, an observation window 20 is provided on the heating mechanism. Specifically, the observation window 20 is composed of openings provided at the same position on the housing 1, the water bladder 2 and the heating element 15. The observation window 20 is located below the hanging hole 9 of the heating mechanism and is close to the hanging hole 9. The length of the housing 1 needs to meet the requirement that when forming a ring-shaped wrapping structure, it will not block the observation window 20. After such setting, it can be ensured that the remaining amount of liquid in the liquid storage container 4 can be clearly observed through the observation window 20. In order to reduce heat loss, in other embodiments, a transparent plastic film can also be provided to cover the observation window 20 to reduce heat loss.

[0053] In one embodiment, the liquid absorbing member includes a receiving bag 11 fixedly connected to the abutting portion 12. The receiving bag 11 contains liquid absorbing swelling particles 10, such as particles made of transparent water-absorbing resin in diapers. The receiving bag 11 can be made of non-woven fabric. Liquid passing holes are provided on the receiving bag 11, and the size of the liquid passing holes is smaller than the initial size of the liquid absorbing swelling particles 10. Setting the liquid absorbing member in the form of the receiving bag 11 and the liquid absorbing swelling particles 10 can not only absorb the leaked liquid, but the porous structure formed by the stacking of the liquid absorbing swelling particles 10 can also intercept solid substances, improving the absorption effect of the exudates.

[0054] In one embodiment, the abutting portion 12 and the connecting portion 13 are detachably connected. Specifically, as Figure 2 and Figure 3 shown, the connecting portion 13 can also be a funnel-shaped structure, and the connecting portion 13 and the abutting portion 12 are connected by threads.

[0055] In one embodiment, as Figure 4 shown, at the junction where one end of the enema tube 3 inserted into the human body abuts against the annular bladder 8, a guiding ring 14 is provided. The guiding ring 14 is made of silicone and is a funnel-shaped structure. The anus is pre-expanded through the guiding ring 14 to facilitate its full contact with the annular bladder 8.

[0056] In one embodiment, as Figure 9 shown, the connecting portion 13 is connected with a first connecting ring 17 that can be sleeved on the enema tube 3. A second connecting ring 18 is rotatably arranged on the enema tube 3 (specifically, an annular groove can be arranged on the enema tube 3, and the second connecting ring 18 is sleeved in the annular groove, so that the second connecting ring 18 can rotate on the enema tube 3 but cannot move up and down). The first connecting ring 17 and the second connecting ring 18 are threadedly connected. The abutting portion 12 is made of an elastic material, and a positioning ring 16 is arranged at the opening of the abutting portion 12 for passing through the enema tube 3. The positioning ring 16 makes the opening of the abutting portion 12 in a stretched state; at the junction of the end of the enema tube 3 inserted into the human body and the annular sac 8, a guiding ring 14 is arranged. The guiding ring 14 is of a funnel-shaped structure and includes a hard portion and a soft portion wrapped on the hard portion (both are funnel-shaped. The hard portion can be made of hard plastic material, and the soft portion can be made of soft silicone). The width of the hard portion is greater than the inner diameter of the positioning ring and less than the outer diameter of the positioning ring. The width of the hard portion is also less than the inner diameter of the first connecting ring 17. After the above settings, after the enema is completed, the liquid in the annular sac 8 can be completely emptied first, and then the second connecting ring 18 is rotated to separate the first connecting ring 17 and the second connecting ring 18. Then, with the liquid in the annular sac 8 completely emptied, the enema tube 3 is pulled outwards, so that the enema tube 3 is gradually pulled out of the human body. As Figure 10 shown, when the guiding ring 14 reaches the positioning ring 16, the positioning ring 16 is pushed upwards, so that the positioning ring 16 is squeezed into the accommodating space. Subsequently, due to the lack of support of the positioning ring 16, the opening of the abutting portion 12 is closed under the dual action of the elastic material's rebound and the squeezing force of the anus, thus blocking the anus. After the enema tube 3 is completely pulled out of the leakage prevention mechanism, the dust-proof sticker on the adhesive tape 19 is torn off, and then the adhesive tape 19 is pasted on the patient's skin, so as to temporarily block the anus after the enema is completed, avoid leakage immediately after the enema is completed, ensure that the medicinal liquid has enough residence time in the body, and ensure the enema effect.

[0057] The above embodiments only represent the specific implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
