Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an intelligent splash-proof enema bag. Background Art

[0002] In the prior art, enema is a treatment method that uses a catheter to be inserted from the anus through the rectum to infuse liquid into the colon to achieve the purpose of defecation and flatulence. It can stimulate intestinal peristalsis, soften and remove feces, and has the effects of cooling, expediting labor, diluting intestinal toxins, reducing absorption, and using low-temperature solutions to cool down patients with high fever. In addition, it can also achieve therapeutic purposes such as supplying medicine, nutrition, and water. Enema is further divided into large-volume non-retention enema, small-volume non-retention enema, retention enema, and cleansing enema. Under normal circumstances, each time an enema is given to a patient, the anal canal must be inserted through the anus, and then the enema liquid is injected to achieve the purpose of the enema; when the patient needs to defecate, the defecation is done in a basin or directly on a nursing pad placed under the buttocks in advance, and then cleaned. Anal bag is a medical device for collecting and caring for feces and other excretions for patients who have undergone rectal, colonic or ileoanal stoma surgery and patients with urinary and fecal incontinence. However, there is currently no device that can meet the various enema needs and stool management of both hospitalized patients, especially ICU patients, and non-hospitalized patients. It cannot meet the needs of this group of people for repeated enema, protection of the skin around the anus, simple hygiene, and saving time and manpower. Therefore, it is necessary to design an enema kit with these functions to meet the daily use of hospitalized and non-hospitalized patients.

[0003] However, for patients undergoing enema treatment for the first time, their fear of the unknown operation, concerns about privacy exposure, and anticipation of pain or discomfort often lead to stress reactions such as anxiety and muscle tension, which in turn affects their cooperation with the operation. In addition, after the enema liquid enters the intestine, its osmotic pressure and mechanical stimulation may induce a strong defecation reflex. At this time, if the patient is unable to effectively control the anal sphincter due to nervousness, or the enema speed is too fast, causing a sudden increase in intestinal pressure, it is easy to cause uncontrollable splashing of enema liquid and feces. Therefore, the present invention proposes an intelligent anti-splash enema bag. Summary of the Invention

[0004] The present invention aims to provide an intelligent, splash-proof enema bag to address the aforementioned issues raised in the background art. For patients undergoing enema treatment for the first time, fear of unknown procedures, concerns about privacy exposure, and anticipation of pain or discomfort often lead to stress reactions such as anxiety and muscle tension, which in turn affect their compliance with the procedure. Furthermore, after the enema liquid enters the intestine, its osmotic pressure and mechanical stimulation may induce a strong defecation reflex. At this time, if the patient is unable to effectively control the anal sphincter due to nervousness, or if the enema speed is too fast, causing a sudden increase in intestinal pressure, it is easy to cause uncontrollable splashing of the enema liquid and feces.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] The device of the present invention will be described below in conjunction with preferred embodiments thereof.

[0034] Example 1:

[0035] As attached Figure 1 To the attached Figure 5 As shown, the present invention provides an intelligent splash-proof enema bag, comprising an enema bag 1, an enema tube 2 and a feces collecting bag 8. The enema tube 2 is passed through the bottom of the enema bag 1, and the other end of the enema tube 2 is sleeved with a sewage collecting shell 3. The outside of the sewage collecting shell 3 is provided with an external support component 6, and the inner surface of the sewage collecting shell 3 is attached with a feces collecting bag 8. The inner cavity of the enema bag 1 is provided with a pressure component 7. A pressure sensor 4 for detecting the pressure in the enema tube 2 is fixedly installed at the bottom of the enema bag 1. The tube body of the enema tube 2 is also provided with a regulating valve 5 for adjusting the infusion flow.

[0036] The outside of the enema bag 1 is provided with a liquid injection port 101 for injecting liquid into the inner cavity.

[0037] As can be seen from the above, the waste collection housing 3 and feces collection bag 8 can effectively collect excrement that may splash during the enema process, preventing environmental contamination. The pressure-applying assembly 7 provides stable pressure for the enema, ensuring a smooth enema procedure. The pressure sensor 4 monitors the pressure within the enema tube 2 in real time, issuing an alarm when pressure is abnormal to ensure patient safety. The regulating valve 5 adjusts the infusion flow rate based on the patient's specific condition, enhancing the comfort and effectiveness of the enema.

[0038] Example 2:

[0039] As attached Figure 3 To the attached Figure 4As shown, this embodiment is essentially the same as the previous embodiment, differing in that the waste collection housing 3 has a tail end 301 and an excretion end 302 at either end, respectively. The tail end 301 can be threaded with the enema tube 2, and a sealing ring is provided at the tail end 301. The inner end of the enema tube 2 extends into the feces collection bag 8 and exits the feces collection bag 8 through the excretion end 302. The diameter of the tail end 301 matches the diameter of the enema tube 2. The outer ring of the excretion end 302 is provided with a connecting strip 303, and the ends of several connecting strips 303 are connected together with an adhesive ring 304.

[0040] An air cushion 305 is located within the cavity enclosed by the adhesive ring 304, the excretion end 302, and the connecting strip 303. When the adhesive ring 304 is attached to the skin around the patient's anus, the air cushion 305 acts as a buffer, reducing the pressure from the adhesive ring 304 on the skin and improving the patient's comfort. Furthermore, the air cushion 305 can deform to the shape of the patient's anus, better fitting the skin and enhancing the seal to prevent excrement leakage.

[0041] The outer periphery of the waste collecting shell 3 is provided with a limiting groove 306, which can precisely cooperate with the external support assembly 6 to ensure that the position of the external support assembly 6 on the waste collecting shell 3 is stable, and by cooperating with the linear movement of the first ring frame 601, the external support assembly 6 is driven to perform the external support action.

[0042] The inner surface of the feces collection bag 8 is coated with a lubricant 801, which directly reduces the friction resistance between the enema tube 2 and the inner wall of the feces collection bag 8. During the insertion process, the lubricant 801 can reduce the mechanical stimulation to the anal and rectal mucosa, reducing the risk of scratches or inflammation.

[0043] Example 3:

[0044] As attached Figure 5 As shown, this embodiment is basically the same as the previous embodiment, except that the outer support assembly 6 includes a first ring frame 601, a connecting rod 602, an L-link 603, a second ring frame 604, a movable block 605, a rubber block 606 and an adjustment block 607. The first ring frame 601 is adjustably sleeved on the limit groove 306 through the adjustment block 607. The ring body of the first ring frame 601 is movably connected to a plurality of connecting rods 602, and the other ends of the plurality of connecting rods 602 are movably connected to the L-link 603. The second ring frame 604 is sleeved on the outside of the sewage collecting shell 3, and the right-angle portions of the plurality of L-links 603 are movably connected to the ring body of the second ring frame 604. The other end of the L-link 603 is movably connected to the rubber block 606 through the movable block 605.

[0045] Specifically, before inserting the enema tube 2, the anus is first expanded to a certain diameter through the external support component 6. While maintaining a moderate expansion state, the enema tube 2 is slowly pushed forward. At this time, the sphincter is in a relaxed state and the resistance is significantly reduced. If resistance is felt during the insertion process, the adjustment block 607 can be fine-tuned to further expand it to avoid forced advancement.

[0046] As can be seen from the above, the first ring frame 601 is located at the far end of the limiting groove 306 away from the anus. At this time, the L-link 603 is in a retracted state, the rubber block 606 is close to the outer wall of the sewage collection shell 3, and the overall structure does not contact the anus area. The medical staff drives the first ring frame 601 to slide along the limiting groove 306 toward the second ring frame 604 by pushing the adjustment block 607. The first ring frame 601 moves: compresses the angle between the connecting rod 602 and the L-link 603, and pushes the right-angled part of the L-link 603 to swing outward. The second ring frame 604 is fixed to the outside of the sewage collection shell 3, serving as the swing of the L-link 603. The fulcrum ensures controllable expansion direction. The end of the L-shaped connecting rod 603, through the movable block 605, drives the rubber block 606 to expand radially toward the anus, forming a uniform annular support surface. The expansion speed of the rubber block 606 is synchronized with the pushing speed of the adjustment block 607, allowing the sphincter to gradually relax under continuous, controllable pressure, avoiding sudden stimulation. The multiple rubber blocks 606 form an annular support, dispersing local pressure and reducing excessive compression in a single area. The synergistic effect of the multi-link mechanical structure and the flexible rubber blocks 606 on the external support assembly 6 achieves progressive, minimally damaging expansion of the anal sphincter. Its movement process is highly controllable and its clinical effectiveness is significantly superior to that of traditional straight tube insertion methods. It is particularly suitable for patients with sensitive anal canals or tight sphincter muscles.

[0047] Example 4:

[0048] As attached Figure 2 As shown, this embodiment is basically the same as the previous embodiment, except that the pressure-applying assembly 7 includes a drive motor 701 fixedly mounted on the top of the enema bag 1, the output end of the drive motor 701 extends through the interior of the enema bag 1 and is connected to a threaded rod 702, the external thread of the threaded rod 702 is connected to a threaded sleeve 703, the bottom of the threaded sleeve 703 is connected to a piston block 704, and the piston block 704 is slidably arranged in the inner cavity of the enema bag 1.

[0049] As can be seen from the above, the pressure-applying component 7 realizes intelligent control of the enema liquid flow rate by working in conjunction with the pressure sensor 4 and the regulating valve 5. The pressure sensor 4 monitors the pressure in the enema bag 1 in real time and transmits the data to the control system. The regulating valve 5 is at a preset opening, and the enema liquid is injected into the patient at a basic flow rate. When the pressure sensor 4 detects that the pressure value is lower than the set threshold, such as the patient's intestinal resistance increases, resulting in a decrease in flow rate, or higher than the threshold, such as the patient's discomfort causing intestinal spasm, the opening of the regulating valve 5 is adjusted first, and an attempt is made to restore the flow rate to the target value by changing the pipeline resistance. If the regulating valve 5 has been adjusted to the maximum opening and still cannot meet the flow rate requirement, the drive motor 701 is started, and the drive motor 701 drives the threaded rod 702 to rotate, and the threaded sleeve 703 moves downward along the threaded rod 702, pushing the piston block 704 to squeeze the liquid in the enema bag 1. During the pressure application process, the pressure sensor 4 continuously monitors the pressure change. If the pressure exceeds the safety upper limit, such as the patient reports pain or the intestinal pressure is too high, the drive motor 701 is immediately stopped and the opening of the regulating valve 5 is reduced. At the same time, the volume of the enema liquid injected is calculated based on the displacement of the piston block 704 to ensure that the total amount is within a safe range. The pressure sensor 4 and the pressure component 7 form a closed-loop control to avoid intestinal perforation or severe discomfort to the patient due to excessive pressure.

[0050] It should be specifically noted that the pressure sensor 4 , the regulating valve 5 and the drive motor 701 are all existing mature technologies, so they will not be described in detail in the specification.

[0051] When in use, inject an appropriate amount of enema liquid into the enema bag 1 through the liquid injection port 101, assist the patient to adopt an appropriate body position such as left lateral decubitus or knee-chest position, expose the anal area, then put the feces collection bag 8 into the excretion end 302 of the sewage collection shell 3 to ensure a good seal, insert the enema tube 2 into the sewage collection shell 3 from the tail end 301, extend it into the feces collection bag 8, and pass it out from the excretion end 302, align the adhesive ring 304 with the skin around the patient's anus, press it lightly to make it fit, use the cushioning effect of the air cushion 305 to reduce the pressure on the skin and ensure the seal, put the first ring frame 601 of the outer support assembly 6 into the limiting groove 306 of the sewage collection shell 3, and the medical staff drives the first ring frame 601 to slide along the limiting groove 306 by pushing the adjusting block 607, driving the L-connecting rod 603 to expand, so that the rubber block 606 gradually expands the anal sphincter to an appropriate diameter. During the expansion process, the patient's reaction should be closely observed to ensure safe and comfortable operation, and then the enema bag 1 is suspended. Hang it at an appropriate height, connect the enema tube 2 to the patient's body, start the system, set the regulating valve 5 to the preset opening, and inject the enema liquid into the patient's body at a basic flow rate. The pressure sensor 4 monitors the pressure in the enema bag 1 in real time and transmits the data to the control system. When the pressure is abnormal and lower than or higher than the set threshold, the opening of the regulating valve 5 is adjusted first to restore the flow rate to the target value. If the regulating valve 5 cannot meet the flow rate requirement, the drive motor 701 is started, and the piston block 704 is pushed to squeeze the enema liquid through the transmission of the threaded rod 702 and the threaded sleeve 703 to increase the pressure. During the pressure application process, the pressure sensor 4 continuously monitors the pressure change to ensure that the pressure is within a safe range. The volume of the enema liquid injected is calculated according to the displacement of the piston block 704 to ensure that the total amount is within a safe range. Finally, the regulating valve 5 is closed and the driving motor 701 is stopped. After the enema liquid is completely emptied, the enema tube 2 is slowly pulled out. The various components work together to realize the intelligent, safe and comfortable enema operation.
