Description

Technical Field

[0001] This utility model belongs to the technical field of medical devices, and specifically relates to an enema bag. Background Technology

[0002] In clinical medicine, enema bags are a commonly used basic medical device, widely applied in various treatment and nursing scenarios such as preoperative bowel preparation, constipation relief, treatment of lower gastrointestinal diseases, and administration of enteral medications. An enema bag generally consists of a reservoir and a delivery tube. It delivers enema fluid into the patient's intestines via gravity or pressure to achieve cleansing or medication administration. During normal use, the delivery tube needs to be inserted into the patient's anus. Because the human body has anal sphincter tissue, the natural contraction of the sphincter can clamp and fix the tube, thereby reducing enema fluid leakage and maintaining unobstructed drainage. Existing products have a simple structure, are suitable for most patients with normal sphincter function, and have a certain clinical application basis.

[0003] However, for some patients with weakened or relaxed sphincter function, such as the elderly, postpartum patients, patients recovering from surgery, or patients with neurological diseases, the sphincter muscles cannot form an effective clamping force during enema procedures. This leads to insecure fixation and poor sealing of the enema tubing, causing the enema solution to easily leak from the outside of the anus during injection. This not only affects the cleaning or drug delivery effect but may also cause patient discomfort, embarrassment, and even the risk of infection. Some patients require repeated enemas or rely on external manual assistance, increasing the burden on medical staff and affecting the independence and privacy of enema procedures. Existing enema bags lack targeted improvements in their structural design for this population, especially in terms of tubing fixation and spill prevention. There is an urgent need for structural innovation to broaden their applicability and improve enema efficacy. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide an enema bag with optimized structure, which is especially suitable for patients with decreased sphincter function or weakened sphincter control ability, so as to solve the problem of enema fluid leakage caused by insufficient sealing during the use of existing enema devices.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An enema bag includes a bag body and a delivery pipe. An air-filled layer is formed around the delivery pipe. A section of the delivery pipe is recessed inward to form an air intake channel. The air intake channel communicates with the air-filled layer and is used to inflate the air-filled layer with air, thereby causing the air-filled layer to expand elastically.

[0006] Furthermore, an inflation pipe is connected to the end of the air intake channel away from the inflation layer, and an inflation connector is formed on the side of the inflation pipe away from the air intake channel that is detachably connected to the inflation pipe.

[0007] Furthermore, the delivery conduit includes a flexible section and an end section for insertion into the patient's body. The end section is made of a material with a hardness greater than that of the flexible section, and the end face of the end section is arc-shaped.

[0008] Furthermore, the end face and side wall of the end section are provided with liquid outlet holes, and the liquid outlet holes on the end face include several tufted holes arranged in a petal-like pattern.

[0009] Furthermore, a one-way valve is provided inside the delivery pipe in the area where the flexible section and the end section meet.

[0010] Furthermore, the surface of the end segment is pre-coated with a water-soluble lubricating layer, which may be a glycerin coating.

[0011] Furthermore, the top of the bag is provided with a liquid inlet, and the bottom area of ​​the bag is provided with a drug injection tube.

[0012] Furthermore, the drug injection tube is angled from one side of the bag towards the other side of the bag.

[0013] The present invention can achieve the following beneficial effects: 1. This application provides an air-filled layer around the delivery pipeline, and inflates the air-filled layer through the air inlet channel, so that the air-filled layer can expand. The inflation volume can be adjusted according to the anal size of different patients, so that when patients have an enema, the expanded air-filled layer can block the patient's anus, reducing the possibility of enema fluid leakage in patients with decreased sphincter function.

[0014] 2. This application provides an inclined drug injection tube at the bottom of the bag. When there is a need for enema solution, the enema solution can be poured into the bag from the top inlet first, and then the drug can be injected from the drug injection tube, so that the injected drug can be more evenly mixed with the enema solution.

[0015] 3. The end of the delivery tube is arc-shaped and pre-coated with a water-soluble lubricating layer, which can reduce the stimulation of the intestinal wall when the delivery tube is inserted into the patient's body; at the same time, the end face and side wall of the end section are provided with liquid outlet holes, and the liquid outlet holes on the end face include several fusiform holes arranged in a petal pattern, which can reduce liquid pressure and avoid damage to the rectal mucosa caused by the enema operation.

[0016] 4. A one-way valve is installed in the delivery pipeline to prevent backflow of the enema fluid. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model belong to the present utility model.

[0020] Furthermore, the described features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a thorough understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details, or other methods, components, apparatuses, steps, etc., can be employed. In other instances, well-known methods, apparatuses, implementations, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0021] like Figures 1 to 4As shown, an enema bag includes a bag body 1 and a delivery tube 2. This enema bag is a disposable medical device. The bag body 1 and the delivery tube 2 can be installed as a single unit or separately and assembled during use. The bag body 1 is transparent and has graduation lines on its surface to facilitate control of the amount of enema fluid injected by medical personnel. An air-filled layer 4 is formed around the periphery of the delivery tube 2 near the outlet end and is fixed to the delivery tube 2. The air-filled layer 4 is made of an elastic material, specifically medical-grade silicone material with a thickness of 0.8 mm. When the air-filled layer 4 is not in use, it adheres tightly to the outside of the delivery tube 2, thereby reducing friction and irritation to the anal wall when the delivery tube 2 is inserted into the patient's anus.

[0022] The delivery pipe 2 has an inwardly recessed section forming an air intake channel 3. This inward recess ensures that the outer wall of the delivery pipe 2 has no protruding structure, reducing the risk of friction and irritation to the patient's anus when the pipe 2 is inserted into the patient's body. One end of the air intake channel 3 connects to the air layer 4, and the other end connects to an inflation tube 5. The connection between the inflation tube 5 and the air intake channel 3 is located in the section that does not need to be inserted into the patient's body. Inflating the air layer 4 through the inflation tube 5 allows the air layer 4 to expand and press against the inner wall of the patient's anus, reducing leakage of the enema fluid. Specifically, the length of the air layer can be designed to be 4cm to cover a 3-5cm area of ​​the internal anal sphincter. The diameter of the inflated air layer can be expanded to 16-22mm, adaptively increasing the diameter according to the degree of relaxation of the patient's anal sphincter.

[0023] An inflation connector 51 is provided on the side of the inflation tube 5 away from the air inlet channel 3. The inflation connector 51 is integrally formed with the inflation tube 5 and is tubular. The enema bag also includes an air inlet pusher 7, which is placed separately. The side wall of the air inlet pusher 7 is provided with a sealing rubber ring. When inflating the inflation layer 4 through the inflation tube 5, the air inlet pusher 7 is inserted into the inflation connector 51, so that the inner wall of the inflation connector 51 and the air inlet pusher 7 are sealed together. During the process of pushing the air inlet pusher 7, gas is injected into the inflation connector 51. The inflation connector 51 and the air inlet pusher 7 use a principle similar to that of a syringe to achieve inflation. It should be noted that since the diameter of the human anus is narrow, the inflation layer 4 only needs to be slightly inflated, and the volume of the inflation connector 51 and the air inlet pusher 7 is also small.

[0024] In addition, after the enema is completed, the air inlet pusher 7 is pulled out first, and then the gas in the air layer 4 is extracted, so that the air layer returns to its initial state, reducing the continuous pressure on the anal sphincter and making it easier for medical staff to pull the delivery tube 2 out of the patient's body.

[0025] Furthermore, the delivery conduit 2 includes a flexible section 21 and an end section 22 for insertion into the patient's body. The end section 22 is made of a material with a higher hardness than the flexible section 21, and its end face is arc-shaped. Discharge holes 211 are provided on both the end face and sidewall of the end section 22. The discharge holes on the end face of the end section 22 are evenly spaced in a petal-like pattern, and the orifices are spindle-shaped. The arc-shaped end section 22 reduces irritation to the intestinal mucosa during insertion, improving the patient's experience. Increasing the hardness of the end section 22 material makes insertion easier. The petal-shaped discharge holes 211 allow the enema fluid to flow out dispersedly, avoiding direct impact on the intestinal wall. The spindle-shaped orifices also create micro-resistance, preventing backflow of the enema fluid.

[0026] Furthermore, a one-way valve 6 is installed inside the delivery pipe 2 at the junction of the flexible section 21 and the end section 22. The one-way valve 6 ensures that the enema fluid can only flow from the bag body 1 along the delivery pipe 2 into the patient's body, preventing the fluid from flowing back from the patient's body into the bag body 1. The one-way valve 6 is inexpensive and has a low cost, effectively preventing the enema fluid from flowing back without increasing the manufacturing cost of the enema bag.

[0027] A water-soluble lubricating layer is pre-coated on the end face and part of the side wall surface of the end section 22. Specifically, the water-soluble lubricating layer can be a glycerin coating with a thickness of 0.05 mm. After contact with water, the coefficient of friction decreases from 0.3 to 0.08. For some patients who have difficulty inserting the delivery tube 2, water can be sprayed to activate the water-soluble lubricating layer before use. Then, the water-soluble lubricating layer can automatically release lubrication when inserted, reducing friction and making it easier to insert the delivery tube 2 into the patient's anus.

[0028] Furthermore, the top of the bag 1 is provided with an inlet 11, and a drug injection tube 12 is inclinedly arranged on the bottom or near the bottom side wall of the bag 1. The drug injection tube 12 is inclined from one side of the bag 1 to the other, and the inside of the drug injection tube 12 is sealed with rubber. The inlet 11 is used to deliver enema fluid into the bag 1, and the enema fluid can be quickly delivered into the bag 1 through the inlet 11; the drug injection tube 12 is used to add therapeutic drugs into the bag 1. Specifically, medical personnel can use a needle to puncture the rubber and inject the drug into the enema bag from the bottom of the bag 1. Because the drug is injected from the bottom of the bag 1 at an incline, the drug and the enema fluid can be fully mixed.

[0029] In summary, this utility model discloses an enema bag suitable for patients with weakened anal sphincter function. The core feature is the inclusion of an air-filled layer 4 on the outside of the delivery pipe 2, and an air-filled system consisting of an air inlet channel 3, an air-filled pipe 5, an air-filled connector 51, and an air-filled pusher 7. This system achieves flexible closure and sealing support of the anus, significantly improving the airtightness and controllability of the enema operation. Simultaneously, the inclusion of a one-way valve 6, a lubricating coating, and petal-shaped discharge holes 211 on the delivery pipe 2 effectively reduces the risk of backflow and tissue irritation, enhancing the patient's enema experience and the safety and convenience of medical procedures. Furthermore, the bag body 1 has an inlet 11 at the top and a drug injection tube 12 at the bottom, further enhancing the device's flexibility and drug mixing efficiency in therapeutic enema scenarios. This utility model has a scientifically designed structure and strong adaptability, making it particularly suitable for elderly individuals, post-operative recovery patients, and other populations with weakened anal sphincter function. It has promising clinical application prospects and industrial application value, and is of positive significance in promoting the development of safer and more humane enema medical devices.
