Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to an enema flushing device. Background Technology

[0002] When patients receive enemas, a disposable enema irrigation device is required. A commonly used enema irrigation device consists of a reservoir bag, a tubing, and an irrigation head. The liquid is injected into the reservoir bag, and the amount of liquid added and the expected amount are recorded by reading the bag. The irrigation head is inserted into the anus to perform the enema and intestinal flushing.

[0003] During use, issues such as untimely fluid flow control or slippage of the irrigation head due to patient anal laxity may cause splashing of excrement or enema solution, creating a psychological burden for medical staff and causing psychological harm to patients. Furthermore, most commercially available enema irrigation devices are single-use, one-piece units, which can be financially burdensome for patients requiring long-term enemas.

[0004] Existing enema irrigation devices lack waste fluid recovery capabilities, meaning patients can only expel waste fluid after the irrigation is complete. If a patient needs to defecate during the procedure, they must either remove the irrigation head midway or endure the discomfort until the enema is finished. This increases the likelihood of repetitive procedures or waste fluid splashing. Furthermore, current enema irrigation devices cannot perform deep irrigation; therefore, further research is needed to achieve this. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an enema flushing device that effectively controls water flow, reduces the probability of waste liquid splashing, achieves the function of flushing and recycling waste liquid simultaneously, and offers a variety of flushing head assemblies to meet different application requirements.

[0006] According to one aspect of this utility model, an enema irrigation device is provided, comprising a reservoir bag, a main conduit communicating with the reservoir bag, and an irrigation head assembly communicating with the main conduit. The irrigation head assembly includes an irrigation head body and an interface component. The main conduit communicates with the interface component. The irrigation head body has a rod portion with ribs arranged circumferentially and protruding outwards. One or more ribs can be provided. An irrigation head and an umbrella-shaped tail are respectively provided at both ends of the rod portion. The outer diameter of the irrigation head is larger than the outer diameter of the rod portion. The top of the irrigation head is arc-shaped, and multiple water outlet holes are distributed circumferentially on the irrigation head. Thus, the irrigation head and ribs are slightly thicker than the rod portion. The irrigation head and ribs contact the intestine, forming a relatively sealed structure to prevent leakage. Furthermore, the ribs can also calculate and sense the insertion depth, providing medical personnel and patients with a direct understanding of the insertion depth of the irrigation head body. The umbrella-shaped tail of the irrigation head body is exposed to the peripheral part of the intestine, reducing the probability of waste fluid splashing and the range of accidental waste fluid splashing.

[0007] In some implementations, the flushing head is a short flushing head or a deep flushing head; The short flushing head has a ball-shaped structure and an arc-shaped transition with the rod. The short flushing head, rod, and umbrella-shaped tail are an integral structure. The deep flushing head is connected to an elongated conduit, which passes through the flushing head assembly and is connected to the main tube. The elongated conduit can extend or retract relative to the flushing head assembly.

[0008] Therefore, a short irrigation head with a rounded shape is used, allowing for smooth insertion into the intestines. A deep irrigation head is used; after insertion, the elongated catheter is pushed to allow the head to penetrate deep into the intestines for irrigation. The water outlet on the deep irrigation head provides a shower-like spray, enabling comprehensive deep irrigation to meet treatment needs.

[0009] In some embodiments, the top end of the interface component is connected to the rod portion of the flushing head body, and the interface component is selected as a single-lumen channel tube or a double-lumen channel tube; If the interface component uses a single-chamber channel tube, the flushing head is a short flushing head, and the other end of the interface component is connected to the main control tube; If the interface piece uses a single-lumen channel tube, the flushing head is a deep flushing head, the deep flushing head is located in front of the rod, and the elongated conduit passes through the rod and the interface piece in sequence and then communicates with the main tube; If the interface uses a dual-lumen channel tube, the flushing head is a deep flushing head, the deep flushing head is located in front of the rod, and the elongated conduit passes through one of the channels of the rod and the interface in sequence and is connected to the main tube, and the other channel of the interface is connected to a return bag.

[0010] Therefore, existing technologies all use single-lumen channel tubes. However, using a dual-lumen channel tube allows for one channel to receive the flushing fluid and another to receive the return fluid, enabling simultaneous flushing and waste fluid recovery. This meets the patient's defecation needs during enema treatment and reduces the chance of accidental leakage. With a deep flushing head, after the head is extended, a gap exists between the inner wall of the rod and the outer wall of the elongated catheter, allowing waste fluid to flow through this gap to the return bag via the dual-lumen interface.

[0011] In some embodiments, the end of the interface fitting adapted to the deep flushing head is provided with an adapter. The interface fitting has a countersunk hole, and the front end of the adapter is embedded in the countersunk hole, with a sealing ring at the connection point. The sealing ring is tightly fitted against the outer wall of the elongated tubing. Therefore, regardless of whether the deep flushing head is equipped with a single-lumen or double-lumen channel tube, the end of the interface fitting used to penetrate the elongated tubing must be equipped with a sealing ring to prevent waste liquid leakage.

[0012] In some embodiments, a flow valve is installed on the main pipe. The flow valve includes a valve body, a knob, and an adjusting plate. The adjusting plate is embedded in the valve body, and the knob is connected to the side of the adjusting plate. The main pipe passes through the adjusting plate, and rotating the adjusting plate changes the cross-sectional flow area inside the main pipe. Thus, rotating the knob drives the adjusting plate to rotate, changing the cross-sectional flow area inside the main pipe. The external knob allows for more rapid flow adjustment. When the adjusting plate is fully open, the flow area is at its maximum, and the flushing fluid flow rate reaches its maximum. When the adjusting plate is gradually closed, the flow area gradually decreases, and the flow rate also decreases, achieving precise control of the flushing fluid flow rate.

[0013] In some embodiments, a pressure ball is installed on the main conduit downstream of the flow valve. One-way valves are installed at both ends of the pressure ball, and a water-stop clamp is installed on the main conduit downstream of the pressure ball. Thus, when the pressure ball is squeezed, the water flow velocity increases; when the pressure ball is released, it returns to its original position, and the water flow velocity decreases. By repeatedly squeezing and releasing the pressure ball, the flushing water flow velocity can be flexibly adjusted, and the one-way valves at both ends prevent liquid backflow.

[0014] In some embodiments, the enema flushing device further includes a plug-in connector, one end of which is connected to the main tube, and the other end of which is connected to an interface fitting or an extension tube. Thus, by using the plug-in connector, the front flushing head assembly and the rear reservoir bag with the main tube are separated into two parts, which can be quickly connected or separated. This modular design breaks away from the traditional one-piece structure, providing product adaptability. Different usage needs can be met simply by replacing different front-end components, saving costs.

[0015] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model optimizes the structure of the irrigation head, adds multiple ribs and slightly enlarges the irrigation head. During use, a relatively sealed structure is formed at the contact point between the irrigation head body and the intestinal wall, reducing the probability of waste liquid leakage. Furthermore, the ribs allow for intuitive perception of the insertion depth. This application provides interface components for single-lumen or double-lumen channels, short irrigation heads, or deep irrigation heads with elongated catheters, forming multiple enema irrigation device structures to meet different needs, such as deep irrigation and waste liquid recovery without removing the irrigation device. The front irrigation head assembly and the rear reservoir bag with the main guide tube form a detachable structure through a plug-in connector, breaking the traditional one-piece structure concept. The replaceable head structure diversifies the product structure and simplifies replacement operations, reducing the economic burden on patients. Attached Figure Description

[0017] The present invention will be further described below with reference to specific embodiments.

[0018] This application provides several enema irrigation devices to meet different application needs, and their structures will be described in detail below.

[0019] Example 1 like Figure 1 As shown, an enema flushing device according to one embodiment of the present invention includes a liquid storage bag 1, a main conduit 2 communicating with the liquid storage bag 1, and a flushing head assembly communicating with the main conduit 2. The liquid storage bag 1 has an injection port 11, which is equipped with a cap 12 and a connector 13. The connector 13 can be connected to a hanging component 14 for hanging, such as a hook or suction cup. The body of the liquid storage bag 1 has a temperature sticker 15.

[0020] The flushing head assembly includes a flushing head body and an interface 4, with the main guide tube 2 connected to the interface 4. The flushing head body has a cylindrical rod 32, which is hollow inside. Outwardly protruding ribs 321 are arranged along the circumference of the outer wall of the rod 32. There may be one or more ribs 321; if multiple, they are evenly spaced. The two ends of the rod 32 have a flushing head 31 and an umbrella-shaped tail 33, respectively. In this embodiment, the rod 32 has two ribs 321, one of which is near the umbrella-shaped tail 33. The outer diameter of the flushing head 31 is larger than the outer diameter of the rod 32. The top of the flushing head 31 is arc-shaped 311 for easy insertion into the intestines. Multiple water outlet holes 312 are distributed along the circumference of the flushing head 31, resulting in a shower-like water flow. The irrigation head 31 and ribs 321 are slightly thicker than the stem 32. The irrigation head 31 and ribs 321 form a relatively sealed structure in contact with the intestine, reducing the probability of leakage. The ribs 321 also function to calculate and sense the insertion depth, providing medical staff and patients with a more intuitive understanding of the insertion depth of the irrigation head. After insertion, the umbrella-shaped tail 33 of the irrigation head is exposed to the peripheral intestinal area, further reducing the chance of waste fluid splashing and the range of accidental splashing.

[0021] The top of the interface piece 4 is inserted into the umbrella-shaped tail 33, and the top of the interface piece 4 is glued to the rod 32 of the rinsing head body. The interface piece 4 is internally connected to the rod 32 of the rinsing head body.

[0022] The rinsing head 31 is either a short rinsing head 31A or a deep rinsing head 31B. In this embodiment, the rinsing head 31 is a short rinsing head 31A. The water outlet 312 of the short rinsing head 31A and the interior of the short rinsing head 31A are sequentially connected to the rod 32. The short rinsing head 31A has a ball-shaped structure and an arc transition 313 with the rod 32. The short rinsing head 31A, the rod 32, and the umbrella-shaped tail 33 are integrally formed. The short rinsing head 31A has a rounded shape and can be smoothly introduced into the intestine.

[0023] Interface component 4 can be either a single-lumen channel tube 4A or a double-lumen channel tube 4B. Figure 5As shown in the figure, in this embodiment, the interface component 4 is a single-lumen channel tube 4A. The top end of the single-lumen channel tube 4A is connected to the rod 32, and the other end of the interface component 4 is connected to the main tube 2 through a plug-in connector 5. Specifically, the plug-in connector 5 is hollow inside. One end of the plug-in connector 5 is inserted into the main tube 2, and the other end of the plug-in connector 5 is inserted into a connecting tube 51. The connecting tube 51 and the interface component 4 are connected by adhesive. In this way, the flushing head body with the short flushing head 31A, the interface component 4, and the connecting tube 51 form one part, and the main tube 2 to the reservoir bag 1 form another part. The plug-in connector 5 enables the quick connection of the two parts. The modular design breaks the traditional integrated structure, provides product adaptability, facilitates manufacturing, and only requires replacing different front-end components to meet different usage needs. It also helps patients save medical costs. In practical applications, the plug-in connector 5 can be fixedly connected to either the connecting tube 51 or the main tube 2, such as by adhesive. As long as at least one end is a pluggable structure, a modular combination can be achieved.

[0024] A water-stop clamp 6 is installed on the main pipe 2 near the plug-in connector 5. The water-stop clamp 6 is closed when the pipe is not connected, or it can be closed in actual operation to prevent liquid in the upstream pipe from entering the downstream pipe of the main pipe 2.

[0025] To better control the flow rate and velocity of the liquid, a flow valve 8 and a pressure ball 7 are installed on the main pipe 2. Specifically, as shown... Figure 3 As shown, the flow valve 8 includes a valve body 81, a knob 82, and an adjusting plate 83. The knob is located on one side of the adjusting plate 83. The knob 82 and the adjusting plate 83 are integrally formed, and the adjusting plate 83 is embedded in the valve body 81. The main tube 2 passes through the adjusting plate 83, and rotating the adjusting plate 83 changes the cross-sectional flow area inside the main tube 2. Rotating the knob 82 drives the adjusting plate 83 to rotate, changing the cross-sectional flow area inside the main tube 2. The external knob 82 is more convenient and faster to adjust than the rolling flow regulator on the traditional infusion tubing. When the adjusting plate 83 is fully open, the flow area is at its maximum, and the flushing fluid flow rate reaches its maximum. When the adjusting plate 83 is gradually closed, the flow area gradually decreases, and the flow rate also decreases, achieving precise control of the flushing fluid flow rate.

[0026] A pressure ball 7 is installed on the pipeline downstream of the flow valve 8. One-way valves 71 are installed at both ends of the pressure ball 7. A water-stop clamp 6 is located on the main conduit 2 downstream of the pressure ball 7. When the pressure ball 7 is squeezed, the water flow speed increases; when the pressure ball 7 is released, it returns to its original position, and the water flow speed decreases. By repeatedly squeezing and releasing the pressure ball 7, the flushing water flow speed can be flexibly adjusted, and the one-way valves 71 at both ends prevent liquid backflow.

[0027] Example 2 The main difference between this embodiment and Embodiment 1 is that the rinsing head 31 of the rinsing head body is different, and the interface component 4 is selected differently. For example... Figure 2 As shown, in this embodiment, the rinsing head 31 is a deep rinsing head 31B, and the interface component 4 is a dual-cavity channel tube 4B.

[0028] Specifically, compared to the short flushing head 31A, the deep flushing head 31B, in addition to having an arc-shaped top end 311, also has a cylindrical extended section 314 extending backward. The interior of the extended section 314 is hollow and communicates with the water outlet 312. The deep flushing head 31B is attached with a long extension tube 34, and the interior of the extension tube 34 communicates with the interior of the extended section 314.

[0029] The interface component 4 is a dual-lumen channel tube 4B, which is similar to a Y-shaped structure. The top end of the interface component 4 is connected to the rod part 32 of the flushing head body by adhesive. One of the channels of the dual-lumen channel tube 4B is used to pass through the extension tube 34 so that the extension tube 34 can communicate with the main tube 2. The other channel is connected to a secondary tube 91, and the end of the secondary tube 91 is connected to a return bag 9.

[0030] To distinguish between the two channels, they are referred to as the first channel 41 and the second channel 42, respectively.

[0031] Specifically, in combination Figure 4 and Figure 5 As shown, the deep flushing head 31B is located in front of the rod 32. The elongated guide tube 34 passes sequentially through the rod 32 and the first channel 41 of the interface piece 4. An adapter 43 is located at the end of the first channel 41, with a hole for the elongated guide tube 34 to pass through. A countersunk hole 411 is formed inside the end of the first channel 41, and the bottom of the countersunk hole 411 is connected to the first channel 41 inside. A stepped protrusion 412 is provided on the inner wall of the countersunk hole 411. An interference portion 431 that mates with the stepped protrusion 412 is provided on the outer periphery of the adapter 43. A sealing ring 44 is embedded at the bottom of the countersunk hole 411. After the front end of the adapter 43 is inserted into the countersunk hole 411, the interference portion 431 of the adapter 43 is squeezed into precise fit with the stepped protrusion 412, and adhesive is applied simultaneously to prevent it from falling off. The sealing ring 44 is tightly pressed against the front end of the adapter 43. When the elongated conduit 34 passes through the first channel 41, the adapter 43 and the sealing ring 44 allow the elongated conduit 34 to move, but the sealing ring 44 can fit tightly against the outer wall of the elongated conduit 34 to prevent waste liquid backflow and leakage.

[0032] After the elongated conduit 34 passes through the first channel 41, it is glued to the connecting tube 51. One end of the connecting tube 51 is pluggable to the pluggable connector 5. The other end of the pluggable connector 5 is pluggable to the main tube 2. The pluggable connector 5 enables a quick connection between the two parts.

[0033] The second channel 42 of the interface component 4 is connected to the secondary conduit 91 by adhesive. The end of the secondary conduit 91 is connected to a return bag 9, and a water-stop clamp 6 is installed on the secondary conduit 91.

[0034] When the enema flushing device is not inserted into the intestine, the rear end of the deep flushing head 31B, i.e., the root of the extended section 314, is attached to the top of the rod 32. The outer diameter of the extension tube 34 is smaller than the inner diameter of the rod 32, and there is a gap 30 between the outer diameter of the extension tube 34 and the inner wall of the rod 32. After insertion, pushing the extension tube 34 separates the root of the deep flushing head 31B from the top of the rod 32, and the water outlet 312 on the deep flushing head 31B sprays water in a shower-like manner. After the deep flushing head 31B is pushed out, the gap 30 between the inner wall of the rod 32 and the outer wall of the extension tube 34 opens, and the waste liquid can enter the rod 32 through the gap 30 and flow from the second channel 42 of the interface 4 and the secondary tube 91 to the return bag 9. The waste liquid will not flow out from the end of the first channel 41 because the end of the first channel 41 has a sealing ring 44.

[0035] If deep flushing is required, hold the interface piece 4 and further push the elongated catheter 34 to allow the deep flushing head 31B to enter the deep intestine for flushing. With the water outlet 312 on the deep flushing head 31B, water is sprayed out in a shower-like manner, which can perform all-round deep flushing to meet the treatment needs.

[0036] The design employs a dual-lumen channel tube 4B in conjunction with a deep rinsing head 31B, allowing rinsing fluid to enter through one channel and return fluid to exit through the other. This enables simultaneous rinsing and waste fluid recovery, meeting the defecation needs of patients during enemas, reducing the chance of accidental waste fluid leakage, and even allowing the deep rinsing head 31B to penetrate deep into the intestines for thorough rinsing.

[0037] Example 3 The main difference between this embodiment and Embodiment 2 is the selection of the interface component 4. For example... Figure 6 As shown, in this embodiment, the rinsing head 31 is a deep rinsing head 31B, and the interface component 4 is a single-cavity channel tube 4A.

[0038] The deep flushing head 31B in this embodiment has the same connector as the deep flushing head 31B in embodiment 2.

[0039] Specifically, the deep flushing head 31B is located in front of the rod 32, through which the elongated conduit 34 passes sequentially through the rod 32 and the single-lumen channel of the interface 4, and exits from the interface 4. An adapter 43 is configured at the end of the single-lumen channel of the interface 4, in conjunction with... Figure 5The connector 4 has a countersunk hole 411 at its end, the bottom of which communicates with the interior of the connector 4. A stepped protrusion 412 is provided on the inner wall of the countersunk hole 411. An interference portion 431, which mates with the stepped protrusion 412, is provided on the outer periphery of the adapter 43. A sealing ring 44 is embedded at the bottom of the countersunk hole 411. After the front end of the adapter 43 is inserted into the countersunk hole 411, the interference portion 431 and the stepped protrusion 412 are precisely fitted together, and adhesive is applied simultaneously to prevent them from falling off. The sealing ring 44 is tightly pressed against the front end of the adapter 43. When the elongated conduit 34 passes through the connector 4, the adapter 43 and the sealing ring 44 allow the elongated conduit 34 to move, but the sealing ring 44 remains tightly against the outer wall of the elongated conduit 34 to prevent backflow and leakage of waste liquid.

[0040] After the elongated conduit 34 passes through the interface piece 4, it is glued to the connecting tube 51. One end of the connecting tube 51 is pluggable to the plug-in connector 5. The other end of the plug-in connector 5 is pluggable to the main tube 2, thus achieving a quick connection between the two parts.

[0041] When the enema irrigator is not inserted into the intestine, the rear end of the deep irrigation head 31B, i.e., the root of the extended section 314, is attached to the tip of the rod 32. The outer diameter of the elongated catheter 34 is smaller than the inner diameter of the rod 32, and there is a gap 30 between the outer diameter of the elongated catheter 34 and the inner wall of the rod 32. After insertion into the intestine, if deep irrigation is required, the connector 4 is held, and the elongated catheter 34 is further pushed to separate the root of the deep irrigation head 31B from the tip of the rod 32, allowing the deep irrigation head 31B to enter deep into the intestine. The water outlet 312 on the deep irrigation head 31B sprays water in a shower-like manner, providing comprehensive deep irrigation to meet treatment needs. This enema irrigator does not have a waste liquid recovery function.

[0042] In this application, there are different types of flushing heads 31 and different types of interface parts 4. The flushing head body at the front end of the product and the liquid storage bag 1 with the main guide tube 2 at the rear end are connected by a plug-in connector 5 to form a detachable structure. This breaks the traditional one-piece structure concept and allows for a replaceable head structure, making the product structure more diversified. It provides a variety of styles of enema flushers to meet different application needs, such as deep flushing and the function of waste liquid recovery without removing the flusher.

[0043] This application also optimizes the structure of the irrigation head, adds multiple ribs 321 and slightly increases the size of the irrigation head 31. During use, the contact area between the irrigation head body and the intestinal wall forms a relatively sealed structure, reducing the probability of waste liquid leakage. Furthermore, through the ribs 321, the patient can intuitively perceive the insertion depth, and medical staff or other nursing staff can also intuitively observe the insertion depth.

[0044] The above descriptions are merely some embodiments of this utility model. It should be noted that those skilled in the art can make other modifications and improvements without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
