Disposable enema bags are essential medical consumables for preoperative preparation of intestinal examinations (such as colonoscopy, barium enema imaging, etc.). Their core function is to standardize intestinal cleaning, clear obstacles in the examination field, ensure diagnostic accuracy, and balance operational safety and patient comfort. They are a key auxiliary tool for improving the efficiency and accuracy of intestinal examinations. The specific functions can be divided into three dimensions: core function, auxiliary value, and adaptation advantages. The details are as follows:
1、 Core function: Clean the intestines and ensure the accuracy of examinations (most importantly)
      The core requirement of intestinal examination is that there is no residual feces in the intestine, otherwise it will block the lesion and affect observation. A disposable enema bag is used to scientifically infuse cleaning solution to achieve intestinal cleaning, laying a solid foundation for the examination
1. Clear the intestinal contents and eliminate visual obstruction
      By utilizing the principle of gravity perfusion, physiological saline and specialized intestinal cleaning solution are uniformly injected into the intestine to promote natural peristalsis, eliminate all feces, residues, and gas accumulation in the intestine, fully expose the inner wall of the intestine, and avoid feces blocking diseased tissues such as polyps, ulcers, inflammation, tumors, etc., thus preventing missed diagnosis and misdiagnosis.
2. Reduce intestinal gas accumulation and improve observation clarity
       During the infusion process, it can gently relieve intestinal spasms, help eliminate stagnant gas in the intestine, avoid intestinal distension causing intestinal dilation and mucosal folds and stacking, and enable colonoscopy or contrast imaging to clearly capture details of the intestinal mucosa, making it easier for doctors to correctly assess intestinal health.
3. Adapt to different inspection requirements and perform targeted cleaning
       Colonoscopy examination: The entire colon (rectum, colon, cecum) needs to be emptied, and a disposable enema bag with a large capacity (1500-2000mL) can meet the needs of divided infusion, achieving no dead corners in the entire intestine and meeting the "intestinal cleanliness level I-II" standard of colonoscopy examination (no or a small amount of residue, not affecting observation);
       Barium enema imaging: There should be no fecal interference with the attachment of barium in the intestine. The enema bag can first clean the intestine and then assist in the infusion of barium to ensure clear and coherent imaging and help determine whether the intestinal morphology is abnormal.
2、 Auxiliary key role: balancing safety and convenience, improving inspection preparation efficiency
       Compared to traditional cleaning methods such as oral laxatives, disposable enema bags can solve the adaptation problem for special populations in intestinal examination preparation, while avoiding risks and simplifying the process
1. Adapt to special populations and make up for the shortcomings of oral hygiene
       For elderly patients who are weak, have difficulty swallowing, have slow intestinal peristalsis, and are intolerant to oral laxatives (vomiting, diarrhea), oral laxatives are prone to poor cleaning or physical intolerance. Disposable enema bags can be directly infused through the rectum, which is fast acting, minimally harmful, and can efficiently complete intestinal cleaning, allowing these special populations to also undergo intestinal examinations smoothly.
2. Aseptic operation to prevent intestinal infection before examination
       Intestinal examination is an invasive procedure, and residual bacteria in the intestine can easily lead to infection after examination. Disposable enema bags are individually packaged with ethylene oxide sterilization, sterile and non allergenic, and will not introduce external bacteria during the infusion process. They are also disposable to avoid cross infection and establish a hygiene defense line for invasive intestinal examination.
3. Properly control the quantity and speed to reduce the risk of intestinal injury
       Equipped with a flow rate regulator and scale markings, it can accurately control the infusion rate (30-50mL/min) and dosage of cleaning solution, avoiding intestinal spasms, abdominal pain, and bloating caused by excessive flow rate and dosage, ensuring patient comfort during the cleaning process, and reducing the impact of discomfort on the examination before the examination.
4. Convenient and efficient operation, reducing preparation time
       No need for complicated preparation in advance, it can be used immediately after opening the box. The hanging design uses gravity to automatically infuse, and can be operated by a single person or family member with assistance. The cleaning effect is fast (5-10 minutes after infusion can be retained for defecation). Compared with oral laxatives that require 4-6 hours to take effect, it greatly shortens the preparation time before intestinal examination and improves the efficiency of hospital examination process.
3、 Exclusive advantages of adapting to intestinal examination: Different from other cleaning tools
1. Better cleaning, suitable for high-precision inspection needs
       Compared to traditional enema bags (which can only clean the rectum) and reusable enema bags (which can leave blind spots), disposable enema bags can achieve deep cleaning from the rectum to the colon, and the cleanliness can meet the medical standards for intestinal examination, making them a high-precision cleaning tool for intestinal examination.
2. The material is soft and skin friendly, avoiding damage to the intestinal mucosa
       The anal canal is made of medical grade soft silicone/PVC, with a rounded and smooth front end that fits snugly against the intestinal mucosa during insertion, without causing damage and avoiding bleeding and infection during examination due to intestinal mucosal damage. It is suitable for colonoscopy and other examinations that require deep penetration into the intestine.
3. Anti reflux design ensures that the cleaning effect is not compromised
       Some special models come with anti reflux valves, which can prevent the backflow of injected cleaning solution, ensure that the cleaning solution fully infiltrates the inner wall of the intestine, improve cleaning efficiency, and prevent backflow of liquid from contaminating the operating environment, ensuring the standardization of intestinal cleaning before inspection.
4、 Core considerations for preparation of intestinal examination (ensuring effective implementation)
       Selection of cleaning solution: Priority should be given to using medical physiological saline or specialized intestinal cleaning solution, with a temperature controlled at 38-40 ℃, to avoid scalding the intestines and causing spasms due to being too cold;
       Infusion height: The suspension height of the liquid storage bag is 60-80cm from the buttocks. If the height is too high, it can easily cause the flow rate to be too fast, and if it is too low, it cannot be infused smoothly;
       Insertion depth of anal canal: 7-10cm for people, to avoid liquid leakage caused by shallow insertion and intestinal damage caused by deep insertion;
       Cleaning standard: The discharge should be clear and free of fecal residue. After meeting the standard, intestinal examination should be carried out to ensure a clear field of view.
