Technical Field

[0001] This invention belongs to the field of rectal irrigation technology, specifically, it relates to a rectal irrigation device with a conveniently replaceable irrigation head and its operating method. Background Technology

[0002] Rectal irrigation is a method of drug administration through the rectum. It involves injecting medication into the rectum, where it is absorbed through the rectal mucosa and exerts its effects. It is mainly used to treat diseases such as constipation, proctitis, perianal abscess, internal hemorrhoids, and intestinal obstruction.

[0003] Chinese patent application CN202320966086.8 discloses a self-controlled rectal medication infusion device. The device includes an infusion unit, a frame, a remote control push module, and a remote controller wirelessly connected to the push module. The infusion unit includes an infusion cylinder with a small hole at the front end and a piston rod adapted to the infusion cylinder. An enema tube is connected to the front end of the infusion cylinder. The frame is equipped with clamping components for mounting the infusion unit. The remote control push module is mounted on the frame, and its output end is a push structure for pushing the piston rod. While this device allows users to perform rectal medication infusion independently and adjust the infusion speed according to their needs, reducing psychological burden, in actual use, infusion involves more than just medication administration; it also includes pre-treatment preparation, such as inserting the flushing head into the patient's anus. These steps cannot be performed independently by the patient using the device alone. Furthermore, the patient needs a specific posture during infusion—lying down or prone—to facilitate proper infusion. This prevents the patient from observing the medication inside the infusion cylinder, making it inconvenient for use.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Rectal drug administration is one of the external treatment methods for internal diseases in Traditional Chinese Medicine (TCM). It is a new clinical drug delivery technique developed based on traditional and modern medical theories. Modern medicine believes that the rectal mucosa has vigorous blood circulation and strong absorption capacity. After being absorbed through the rectum, drugs enter the systemic circulation in three ways: first, via the middle rectal vein and anal canal vein, bypassing the liver and directly entering the systemic circulation, thus preventing and reducing drug changes in the liver and avoiding the influence of the stomach and small intestine; second, via the superior rectal vein, through the portal vein, into the liver for metabolism, and then recirculate throughout the body; and third, after absorption through the rectal lymphatic system, entering the bloodstream via the cisterna chyli and thoracic duct.

[0037] Enteral drug delivery therapy has the following advantages: it is simple, safe, and efficient, improving the smoothness of drug administration, reducing the pain of injections, and eliminating the discomfort of oral medication, making it suitable for infants and young children who have difficulty taking injections or oral medications; it reduces the time spent in hospital for injections, saves healthcare resources, and lowers medical costs; the bioavailability of rectal administration is as high as 97.5%; drugs enter the systemic circulation directly through the rectal vein and anal canal, improving bioavailability; it also prevents and reduces the toxic side effects of drugs on the liver, reduces the burden on the liver, and protects the liver; drugs do not pass through the stomach and small intestine, avoiding the influence and destruction of drugs by acids, alkalis, and digestive enzymes, reducing the irritation of drugs to the digestive tract, and protecting gastrointestinal organs; it is convenient, comfortable, safe, and not limited by conditions; for patients who are comatose or vomiting and cannot take oral medication, rectal administration is faster and facilitates emergency treatment.

[0038] Rectal administration is the third important route of drug delivery besides oral and injection. It includes rectal injection, i.e., anal irrigation. Rectal injection therapy can be used to treat various systems in children, such as fever, acute upper respiratory tract infection, tonsillitis, bronchitis, pneumonia, bronchial asthma, diarrhea, gastroenteritis, bacterial diseases, allergic purpura, nephrotic syndrome and many other diseases.

[0039] Rectal irrigation is a method of drug administration via the rectum. It involves injecting medication into the rectum, where it is absorbed through the rectal mucosa and exerts its effect. It is primarily used to treat constipation, proctitis, perianal abscesses, internal hemorrhoids, and intestinal obstruction. For constipation: Instilling lubricating medication into the rectum softens stool and facilitates smooth passage, thus treating constipation. For proctitis: Instilling anti-inflammatory medication into the rectum allows for rapid absorption by the rectal mucosa, effectively reducing congestion and edema. For perianal abscesses: Perianal abscesses occur at the junction of the anus and rectum; therefore, rectal administration allows for direct application to the affected area, resulting in rapid relief. For internal hemorrhoids: Internal hemorrhoids are located above the dentate line of the anus; rectal irrigation can also be effective in reducing the size of the lesion and alleviating symptoms. For intestinal obstruction: Rectal irrigation reduces pressure within the intestines, relieving symptoms of intestinal obstruction.

[0040] With changing lifestyles, sedentary lifestyles, high-fat and high-protein diets, chronic constipation, and staying up late lead to prolonged accumulation of intestinal toxins in the body, increasing the incidence of colorectal cancer and gastrointestinal and skin diseases. Furthermore, the rectum is the waste collection point for the body's digestive system; digestive residues accumulate here, creating an ideal breeding ground for bacteria and toxins. If these residues are not properly eliminated, it can easily lead to internal and external hemorrhoids, eczema, and other diseases, causing significant suffering. Therefore, enemas may be necessary in some cases.

[0041] Rectal enema is typically administered using an enema kit. Before the enema, the patient should be instructed to empty their bladder and bowels. The enema kit is then inserted into the rectum through the anus. The volume of enema fluid is generally less than 100 mL, typically around 50 mL. In winter, the enema solution is heated to prevent it from becoming too cold and irritating the rectum. After the enema, the patient should be kept in an elevated position to allow the enema solution to remain in the body for as long as possible for better results, usually about an hour. If the patient feels uncomfortable, they can go to the toilet to expel the enema solution. A prone or left lateral decubitus position is recommended to facilitate drug absorption. After the injection, the patient should remain in this position for six to fifteen minutes to allow the drug to enter the intestinal tract and be absorbed.

[0042] A rectal delivery device, also known as a rectal injector or rectal irrigator, is a medical device used to deliver medication to a patient via the rectum. It typically consists of a container that holds the medication and a tube inserted into the rectum. Rectal delivery devices can be used for several purposes: Medication: Medications are absorbed through the rectal mucosa via a rectal delivery device, thus achieving a therapeutic effect. This method is particularly suitable for patients who cannot take oral medication or receive intravenous injections, such as those with digestive system disorders, nausea, vomiting, or limited oral absorption. Examination: Rectal delivery devices can also be used to examine the pathological condition of the rectum and colon, such as for colon X-rays performed by injecting contrast agents. Defecation: For patients with constipation or difficulty defecating in certain situations, rectal delivery devices can stimulate intestinal peristalsis and promote defecation by infusing fluid. The use of a rectal delivery device is relatively simple, but requires guidance and supervision from a doctor or nurse. Before use, the patient should keep the anus clean and apply a water-soluble lubricant to the tip. Then, gently insert the rectal delivery device and inject the medication or liquid into the rectum as directed by the doctor. It is important to note that strict aseptic techniques must be followed when using rectal applicators to prevent infection. After use, the rectal applicator should be thoroughly cleaned and disinfected to ensure safety for the next use.

[0043] Rectal drug delivery devices are medical devices used for rectal administration of medications. They have the following characteristics: Recommended for patients who cannot absorb medications orally or intravenously, such as those experiencing motion sickness, seasickness, or postoperative nausea. Rectal drug delivery devices are in the form of patches or enemas, absorbed through the rectum, bypassing gastric digestion and hepatic blood flow to directly enter the bloodstream, thus improving drug absorption. Rectal drug delivery devices provide a stable delivery rate and dosage, helping to maintain blood drug concentrations within the therapeutic range. They are easy to use; simply place the medication into the device and insert it into the rectum to complete the administration. The administration process is relatively safe, especially for children, the elderly, and patients who cannot chew or swallow medications. Adverse reactions such as gastrointestinal irritation and gastric ulcers are rare, reducing side effects during medication administration. It is important to note that rectal drug delivery devices are only suitable for specific medications and situations and should be used correctly under the guidance of a physician. Hygiene and sterilization procedures must also be followed during use.

[0044] A rectal delivery device is a device used to administer medication through the rectum. Its main functions include: bypassing the gastrointestinal tract: Some patients cannot achieve the effects of oral medication due to gastrointestinal problems (such as vomiting, intestinal obstruction, etc.). A rectal delivery device can bypass the gastrointestinal tract, delivering medication directly to the rectum, thus achieving rapid absorption and action. Local treatment: Some medications can have special therapeutic effects when acting directly on the rectal mucosa. For example, in treating diseases such as proctitis and rectal cancer, a rectal delivery device can deliver the medication directly to the affected area for better therapeutic results. Long-term medication administration: In cases requiring long-term medication, oral medication may be inconvenient or unsuitable. A rectal delivery device can serve as an alternative, allowing patients to conveniently and continuously administer medication. Special populations: For special populations who cannot use oral medication, such as children and comatose patients, a rectal delivery device can provide a suitable method of medication administration.

[0045] A rectal applicator is a device used to inject medication directly into the rectum. The following are general instructions for use: Preparation: Clean the rectal applicator thoroughly and apply a suitable amount of lubricant. Adopt the correct position: Adopt a left lateral decubitus position or a knee-chest position, bending your left leg forward and extending your right leg backward. Insert the rectal applicator: Slowly insert the rectal applicator into the anus, stopping when you feel some resistance. Inject the medication: Insert the syringe into the injection tubing of the rectal applicator and slowly inject the medication. After injection, keep the rectal applicator in the anus for several minutes to ensure adequate absorption of the medication. Remove the rectal applicator: Slowly withdraw the rectal applicator, then maintain the lateral decubitus or knee-chest position for a period of time to prevent medication leakage.

[0046] When using a rectal applicator, please note the following: First, ensure the rectal applicator is intact and undamaged or contaminated. Always wash your hands and wear disposable gloves before use. Prepare the required medication in advance and pour it into the rectal applicator according to your doctor's instructions or the instructions on the package insert. Before use, check the rectal applicator for air bubbles; if present, squeeze or gently tap to expel them. When using the rectal applicator, adopt an appropriate posture, such as lying down, semi-reclining, or bending forward, to facilitate better insertion into the rectum. Apply a lubricant before insertion to reduce discomfort. Insert the rectal applicator slowly and gently to avoid irritating or damaging the rectal wall. After insertion, gradually inject the medication into the rectum, rather than injecting it all at once. After medication injection, maintain a lying position to prevent the rectal applicator from dislodging. Clean the rectal applicator promptly after use to avoid cross-infection or contamination from residual medication. If any discomfort or abnormal symptoms occur, discontinue use immediately and consult a doctor.

[0047] An infusion device is a medical device that precisely controls the infusion volume and rate. It can adjust the infusion rate and volume to meet different patient treatment needs. The main functions of an infusion device are as follows: Precise control of drug infusion volume: In clinical treatment, many drugs need to be infused according to specific dosages. Using an infusion device, the infusion volume can be accurately calculated according to the doctor's orders, thereby ensuring the efficacy and safety of the drugs. Adjustment of infusion rate: Different drugs have different infusion rates. Using an infusion device, the fluid flow rate can be adjusted to avoid infusions that are too fast or too slow, reducing the incidence of adverse drug reactions. Ensuring infusion quality: An infusion device can avoid problems such as infusions that are too fast or too slow, improving infusion accuracy and quality, thereby improving treatment effects and the patient's quality of life.

[0048] The invention will now be described in further detail with reference to the accompanying drawings.

[0049] Please see Figure 1-6 As shown, this embodiment provides a rectal irrigation device with a convenient replacement irrigation head, including a base 1. A movable plate 2 and a push plate 5 are slidably fitted on the top of the base 1. A placement groove 3 is provided on the top of the movable plate 2.

[0052] One application of this embodiment is as follows: During use, the prepared medication is added to the infusion cylinder 4, and then the infusion cylinder 4 is placed into the placement groove 3, so that the infusion cylinder 4 and the placement groove 3 are engaged. During the installation of the infusion cylinder 4, one end of the piston rod 7 is also engaged with the push plate 5. After installation, the enema bend 12 is placed into the fixing groove 11, so that the enema bend 12 and the fixing groove 11 are engaged, so that the flushing head 13 corresponds to the groove of the seat plate 10. Then, the pushing component 6 is adjusted, so that the pushing component 6 pushes the push plate 5 to move. The push plate 5 will push the moving plate 2 inward through the adjustment component. The moving plate 2 and the push plate 5 move together to move the irrigation cylinder 4, so that one end of the irrigation cylinder 4 is connected to one end of the enema bend 12. Then, the adjusting component is adjusted to separate the connection between the moving plate 2 and the push plate 5. Then, the patient can sit on the top of the seat plate 10 and the flushing head 13 is inserted into the patient's anus. Then, the pushing component 6 is adjusted, which will push the push plate 5 to continue moving, so that the push plate 5 drives the piston rod 7 to move. The piston rod 7 can push the medicine in the irrigation cylinder 4 into the enema bend 12. The medicine is sprayed out through the enema bend 12 to the flushing head 13 to irrigate the patient.

[0053] The seat plate 10 allows the enema tube 12 to be secured in the fixed groove 11, aligning the flushing head 13 with the groove of the seat plate 10. This allows the patient to sit on the seat plate 10 for irrigation, facilitating insertion of the flushing head 13 into the anus.
