Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular 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 for enema: 1. Prepare enema solution: Normal saline, soapy water, etc. are usually used. Choose the appropriate enema solution according to specific needs and doctor's advice. 2. Patient preparation: Assist the patient to take the left side lying position with legs bent and buttocks exposed. 3. Lubricate the anal canal: Apply lubricant to the front end of the anal canal to reduce friction and discomfort during insertion. 4. Insert the anal canal: Slowly insert the anal canal into the anus about 7-10 cm. Pay attention to observe the patient's reaction during insertion. If discomfort or pain occurs, stop immediately. 5. Infuse enema solution: Fix the anal canal and slowly pour the enema solution into the enema bag to let the enema solution flow naturally into the intestine. 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 in time and take corresponding measures. 7. Pull out the anal canal: When the enema solution is filled, clamp the end of the anal canal with hemostatic forceps and gently pull out the anal canal. Let the patient lie flat and rest for a while so that the enema solution can fully take effect.

[0003] The elderly are one of the main groups of people who need enema. The levator ani muscles of the elderly are more relaxed than those of the young, which can easily lead to defecation while enema, making it difficult for the enema liquid to fully exert its effect, which not only affects the enema effect, but also causes contamination of clothing and mattresses. Summary of the invention

[0004] Aiming at the problem that the elderly are prone to defecating while 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 comprises an enema tube and a liquid storage container filled with enema liquid, 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 anti-leakage mechanism comprises a primary anti-leakage structure, which comprises an annular bag arranged on the enema tube, wherein liquid is arranged in the annular bag, and a liquid inlet and outlet are also arranged on the annular bag. When the enema tube is inserted into the human body, whether to add liquid or drain liquid and the amount of added liquid or drained liquid are determined according to the flow of liquid in the annular bag;

[0008] The leakage prevention mechanism also includes a secondary leakage prevention structure, which includes an abutment member arranged on the enema tube, the abutment member includes an abutment portion and a connecting portion connected to each other, the connecting portion is connected to the enema tube, the abutment portion is funnel-shaped, and the abutment portion and the connecting portion together form a accommodating space, the abutment portion is sleeved on the annular sac, and one end of the annular sac is located in the accommodating space, the annular sac is made of elastic material, and the part of the annular sac located in the accommodating space has greater elasticity than other parts.

[0009] After adopting this technical solution, the present invention is provided with a two-stage leak-proof structure, the first-stage leak-proof structure is wrapped around one end of the enema tube inserted into the human body, and liquid is arranged in the annular pouch. During the process of inserting the enema tube into the human body, if the user's levator ani muscles have sufficient strength, the liquid with fluidity in the annular pouch will be blocked outside the anus. At this time, since the elasticity of the part of the annular pouch located in the accommodating space is greater than that of other parts, the liquid in the annular pouch flows to one end of the accommodating space in the second-stage leak-proof mechanism and the end of the annular pouch located in the accommodating space expands, thereby applying a thrust to the abutting part of the second-stage leak-proof structure, so that the abutting part is fully abutted against the anus, thereby preventing leakage during enema. If the operator finds that one end of the annular pouch located in the accommodation space does not expand significantly during the process of inserting the enema tube into the human body, it means that the user's levator ani muscle is not strong enough or is relatively loose. At this time, liquid can be added to the annular pouch to expand the end of the annular pouch located in the accommodation space. Since the volume of the accommodation space is limited, when the accommodation space expands sufficiently, the remaining part also expands with the addition of liquid, so that the part of the annular pouch in contact with the anus expands, thereby fully contacting the anus to prevent liquid from flowing out. During the process of adding liquid, the operator can slightly twitch the enema tube. If it is found that the liquid has obvious flow, it means that the annular pouch is in full contact with the anus, then the addition of liquid can be stopped and normal enema operation can be performed. The present invention blocks the anus by setting a two-stage leak-proof structure, which effectively reduces the risk of leakage while filling, and is suitable for patients with different anus sizes, which can effectively ensure the enema effect.

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

[0011] After adopting this technical solution, one end of the annular bag 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 end of the annular bag detachably connected to the enema tube can be disassembled, and the liquid in the annular bag flows downward under the action of gravity, driving the annular bag to flip over, thereby flipping the end inserted into the human body to the inside, avoiding causing discomfort to the operator.

[0012] Preferably, the connecting portion is threadedly connected to the enema tube, and one end of the annular bag is arranged at the threaded connection between the connecting portion and the enema tube.

[0013] After adopting this technical solution, a detachable connection between one end of the annular bag and the enema tube is achieved by crimping one end of the annular bag to the threaded connection between the connecting part and the enema tube.

[0014] Preferably, it also includes a heating mechanism that can be mounted on the liquid storage container, the heating mechanism includes a shell, a water bag is arranged on the inner surface of the shell, a heating element and a temperature detection element are arranged between the shell and the water bag, and a temperature control component electrically connected to the heating element and the temperature detection element is arranged on the shell.

[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 the heating mechanism is a water bag type. After the enema liquid in the liquid storage container is preheated, 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.

[0016] Preferably, the water bag is provided with a liquid discharge pipe and a liquid filling pipe, the liquid discharge pipe is connected to a bidirectional micro pump provided on the shell, and the bidirectional micro pump is detachably connected to the liquid inlet and outlet of the annular bag.

[0017] After adopting this technical solution, when the enema is finished, part of the liquid in the annular bag can be sucked back into the water bag, so that the volume of the annular bag becomes smaller and it is easy to take out, and water resources can also be saved.

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

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

[0020] After adopting this technical solution, the abutting part is made of a flexible material with a certain supporting strength, so that it has a certain deformation ability to fit the anus more closely, and also has sufficient resistance.

[0021] Preferably, a liquid absorbent is provided on the side of the abutting portion in contact with the anus, and the liquid absorbent includes a receiving bag fixedly connected to the abutting portion, the receiving bag is filled with liquid-absorbing swelling particles, and the receiving bag is provided with a liquid passing hole, and the size of the liquid passing hole is smaller than the initial size of the liquid-absorbing swelling particles.

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

[0023] After adopting this technical solution, the anus is expanded in advance through the guide ring to facilitate its full contact with the annular sac.

[0024] Preferably, the connecting portion is connected to a first connecting ring which can be sleeved on the enema tube, a second connecting ring is rotatably provided on the enema tube, the first connecting ring and the second connecting ring are threadedly connected, the abutting portion is made of elastic material, and a positioning ring is provided at an opening on the abutting portion for passing the enema tube, the positioning ring makes the opening of the abutting portion in a stretched state; a guide ring is provided at the junction of the end of the enema tube inserted into the human body and the annular pouch, the guide ring is a funnel-shaped structure, and includes a hard portion and a soft portion wrapped on the hard portion, the width of the hard portion is larger than the inner diameter of the positioning ring and smaller than the outer diameter of the positioning ring, and the width of the hard portion is also smaller than the inner diameter of the first connecting ring.

[0025] Furthermore, an adhesive tape is provided on the connection portion, and a dustproof sticker is provided on the adhesive tape.

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

[0027] The present invention is provided with a two-stage leak-proof structure. The first-stage leak-proof structure is wrapped around one end of the enema tube inserted into the human body. Liquid is arranged in the annular pouch. During the process of inserting the enema tube into the human body, if the user's levator ani muscles have sufficient strength, the liquid with fluidity in the annular pouch will be blocked outside the anus. At this time, since the elasticity of the part of the annular pouch located in the accommodating space is greater than that of other parts, the liquid in the annular pouch flows to one end of the accommodating space in the second-stage leak-proof mechanism and the end of the annular pouch located in the accommodating space is expanded, thereby applying a thrust to the abutting part of the second-stage leak-proof structure, so that the abutting part is fully abutted against the anus, thereby preventing leakage during enema. If the operator finds that one end of the annular pouch located in the accommodation space does not expand significantly during the process of inserting the enema tube into the human body, it means that the user's levator ani muscle is not strong enough or is relatively loose. At this time, liquid can be added to the annular pouch to expand the end of the annular pouch located in the accommodation space. Since the volume of the accommodation space is limited, when the accommodation space expands sufficiently, the remaining part also expands with the addition of liquid, so that the part of the annular pouch in contact with the anus expands, thereby fully contacting the anus to prevent liquid from flowing out. During the process of adding liquid, the operator can slightly twitch the enema tube. If it is found that the liquid has obvious flow, it means that the annular pouch is in full contact with the anus, then the addition of liquid can be stopped and normal enema operation can be performed. The present invention blocks the anus by setting a two-stage leak-proof structure, which effectively reduces the risk of leakage while filling, and is suitable for patients with different anus sizes, which can effectively ensure the enema effect.

[0028] Elderly people 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, 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.

DETAILED DESCRIPTION

[0040] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0042] like Figure 1-6 As shown, an enema device includes an enema tube 3 and a liquid storage container 4 filled with enema liquid. Figure 1 As shown ( Figure 1 The cutoff part in the middle indicates that the enema tube 3 has an indefinite length), the liquid storage container 4 is an enema bag, and in other embodiments, it can also be a bottled enema liquid, etc., and its structure is the same as that of the prior art, so it is not repeated 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] like Figure 2As shown, the leakage prevention mechanism includes a primary leakage prevention structure, which includes an annular bag 8 arranged on the enema tube 3, and a liquid is arranged in the annular bag 8. In this embodiment, the liquid is water, and in other embodiments, it can also be other liquids as long as it has good fluidity; the annular bag 8 is also provided with a liquid inlet and outlet, and a pipeline is provided at the liquid inlet and outlet. A liquid stop valve is provided on the pipeline, and the pipeline can also be opened or closed by the liquid stop valve (not shown in the figure), and liquid can be added to the annular bag 8 or discharged through the pipeline; in this embodiment, the annular bag 8 is made of hospital silicone material, which is elastic and can be retracted, and the end located in the accommodating space is more elastic, that is, it is looser and easier to be expanded; the length of the annular bag 8 is about 10-12cm to meet the insertion depth requirement of the enema tube 3, and the end of the annular bag 8 is about 0-2cm away from the end of the enema tube 3, which is about 0.5cm in this embodiment; during the insertion of the enema tube 3 into the human body, whether to add liquid or discharge liquid and the amount of adding or discharging liquid are determined according to the flow of liquid in the annular bag 8;

[0044] The specific usage and function of the first-level leak-proof structure are as follows: Figure 2-5 As 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 amount can be set according to the age, etc., so that the size of the annular pouch 8 after the initial amount of liquid is added 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 condition, but also needs to pay attention to the flow of the liquid in the annular pouch 8. If the liquid in the annular pouch 8 flows significantly, the part of the annular pouch 8 located in the accommodation space will swell (from Figure 2 becomes Figure 3 ), it means that the patient's levator ani muscles have sufficient strength, and the annular pouch 8 is tightly fitted with the anus, achieving a preliminary leak-proof effect; if the liquid in the annular pouch 8 does not flow significantly, and the end of the annular pouch 8 located in the accommodating space does not swell significantly, it means that the user's levator ani muscles are insufficient or relatively loose. At this time, liquid can be added to the annular pouch 8 to make the end of the annular pouch 8 located in the accommodating space swell. Since the volume of the accommodating space is limited, when the accommodating space swells large enough, the remaining part also swells with the addition of liquid, so that the part of the annular pouch 8 in contact with the anus swells, thereby fully contacting with the anus. During the process of adding liquid, the operator can slightly pull the enema tube 3. If it is found that the liquid has obvious flow, it means that the annular pouch 8 is in full contact with the anus, then the addition of liquid can be stopped, thereby achieving a preliminary leak-proof effect.

[0045] The anti-leakage mechanism also includes a secondary anti-leakage structure, which includes an abutment member arranged on the enema tube 3, and the abutment member includes an abutment portion 12 and a connection portion 13 connected to each other. The abutment portion 12 can be made of soft silicone or soft rubber. In this embodiment, it is made of medical soft silicone and has a thickness of about 0.5-1 cm to ensure that it has sufficient support force and deformation capacity; the connection portion 13 is made of hard transparent plastic material to facilitate observation of whether the annular bag 8 is expanded. The connection portion 13 is also provided with an opening that cooperates with the pipeline of the liquid inlet and outlet of the annular bag 8, and the size of the opening should be The size of the pipe is larger than that of the liquid inlet and outlet, so that the pipe of the liquid inlet and outlet can pass through; the connecting part 13 is connected to the enema tube 3, the abutting part 12 is in the shape of a circular funnel, and the abutting part 12 and the connecting part 13 jointly form a accommodating space, the large end of the abutting part 12 is connected to the connecting part 13, and the small end thereof is sleeved on the annular sac 8, and the diameter of the small end is larger than the diameter of the annular sac 8 after expansion, so that the liquid in the annular sac 8 can enter the accommodating space; the side of the abutting part 12 in contact with the anus is provided with a liquid absorbent, through which the seeped liquid can be absorbed to avoid soiling the mattress and clothes.

[0046] The specific usage and function of the secondary leak-proof structure are as follows: the abutment portion 12 is located at 7-10 cm of the enema tube 3. When the anus reaches the abutment portion 12, it means that the enema tube 3 has been inserted 7-10 cm, and the insertion can be stopped, which serves as a mark of the insertion end point; after the insertion is completed, the abutment portion 12 abuts against the anus. When the annular bag 8 expands in the accommodating space, it will generate an abutment force on the abutment portion 12, thereby causing the abutment portion 12 to be slightly deformed, so that the abutment portion 12 is more closely attached to the anus and the gap is reduced. The liquid absorbent on the abutment portion 12 can absorb a small amount of liquid that may seep out, thereby achieving a secondary leak-proof effect.

[0047] The anus is blocked by the cooperation of the primary and secondary leak-proof structures, which effectively reduces the risk of leakage during enema. It is suitable for patients with different anus sizes and 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 enema tube 3 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 threadedly connected, and one end of the annular pouch 8 is arranged at the threaded connection between 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 crimping one end of the annular pouch 8 at the threaded connection between the connecting portion 13 and the enema tube 3. The rest of the annular pouch 8 is in contact with the outer wall of the enema tube 3 but is not connected thereto; when the enema tube 3 needs to be pulled out after the enema is finished, 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 pulled out. At this time, since the annular pouch 8 is in close contact with the anus and the intestine, the friction force is relatively large, so the enema tube 3 will be pulled out of the human body first, and then as the enema tube 3 continues to be pulled out, the end of the annular pouch 8 fixedly connected to the enema tube 3 is pulled out as the annular pouch 8 is pulled out, thereby forming a flip of the annular pouch 8 in the human body, so that when the annular pouch 8 is completely pulled out, the side with dirt is located inside the annular pouch 8, which cannot be seen by the operator, reducing his discomfort; in other embodiments, the enema tube 3 can also be pulled out 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 downward, and the liquid in the annular pouch 8 flows downward under the action of gravity, driving the annular pouch 8 to complete the flip (such as Figure 7 and Figure 8 As shown), the end inserted into the human body is turned inward to avoid causing discomfort to the operator.

In this embodiment, the heating element 15 can be an electric heating film, which is flexible and can adapt to the bending of the heating mechanism; the heating element 15 is arranged between the water bag 2 and the shell 1, and the heating element 15, the water bag 2 and the shell 1 are a whole. The heating element 15 generates heat after being started, and transfers the heat to the liquid in the water bag 2 through heat conduction, so that the temperature of the liquid in the water bag 2 increases, and when the water bag 2 is wrapped on the liquid storage container 4, the heat can be transferred to the enema liquid, thereby achieving the heating of the enema liquid, 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 larger, so that the liquid in the water bag 2 can be quickly heated.

[0050] In one embodiment, the water bag 2 is provided with a liquid discharge pipe and a liquid supply pipe 5, the liquid discharge pipe is connected to a two-way micro pump 7 provided on the housing 1, and the two-way micro pump 7 is detachably connected to the liquid inlet and outlet of the annular bag 8. When the enema is finished, part of the liquid in the annular bag 8 can be sucked back into the water bag 2, so that the volume of the annular bag 8 becomes smaller and easier to take out, and water resources can also be saved. After the enema liquid in the liquid storage container 4 is preheated, part of the liquid in the water bag 2 can be discharged 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 the annular bag 8 causing discomfort to the patient when it contacts the human body.

[0051] In one embodiment, the shell 1 is made of cloth, soft silicone or soft rubber, and in this embodiment, it is made of high temperature resistant soft silicone, and the inner surface of one end of the shell 1 is provided with a hook surface Velcro 6, and the outer surface of the other end is provided with a fleece surface Velcro that matches it, and a detachable connection is achieved by the cooperation between the hook surface Velcro 6 and the fleece surface Velcro, and a hanging hole 9 is provided on the shell 1, through which the heating mechanism can be hung on the infusion stand, so that it can be sleeved on the liquid storage container 4 also hung on the infusion stand.

Specifically, the observation window 20 is composed of an opening provided at the same position on the housing 1, the water bag 2 and the heating element 15. The observation window 20 is located below the hanging hole 9 of the heating mechanism and is provided close to the hanging hole 9. The length of the housing 1 must be sufficient to form a ring-shaped wrapping structure without blocking the observation window 20. After such a 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 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, and 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, and the receiving bag 11 is provided with a liquid-passing hole, and the size of the liquid-passing hole is smaller than the initial size of the liquid-absorbing swelling particles 10. The liquid-absorbing member is configured in the form of a receiving bag 11 and liquid-absorbing swelling particles 10, which can not only absorb the exuded liquid, but also the porous structure formed by stacking the liquid-absorbing swelling particles 10 can intercept solid objects and improve the absorption effect of the exudate.

How to set it up so that after the enema is finished, the liquid in the annular pouch 8 can be completely emptied first, and then the second connecting ring 18 can be rotated to separate the first connecting ring 17 and the second connecting ring 18, and then the enema tube 3 can be pulled outward when the liquid in the annular pouch 8 is completely emptied, so that the enema tube 3 is gradually pulled out of the human body, such as Fig.10 As shown, when the guide ring 14 reaches the positioning ring 16, it pushes the positioning ring 16 to move upward, thereby squeezing the positioning ring 16 into the accommodating space. Subsequently, due to the lack of support from the positioning ring 16, the opening of the abutment portion 12 is closed under the dual effects of the elastic material rebound and the anus squeezing force, thereby blocking the anus. After the enema tube 3 is completely pulled out of the leak-proof mechanism, the dustproof sticker on the tape 19 is torn off, and then the tape 19 is pasted on the patient's skin, thereby temporarily blocking the anus after the enema is completed, avoiding leakage immediately after the enema is completed, ensuring that the drug solution has a sufficient residence time in the body, and ensuring the enema effect.

[0057] The above-mentioned embodiments only express the specific implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the protection scope of the present application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the technical solution concept of the present application, and these all belong to the protection scope of the present application.
