[0017] In the medical field, reducing the core body temperature is an important treatment method. Especially in some specific diseases and surgeries, such as cardiac surgery and brain injury treatment, reducing the core body temperature can reduce tissue metabolic requirements, protect the functions of important organs, and improve the survival rate of patients. As a traditional medical method, enema can not only stimulate intestinal peristalsis, expel intestinal gas, eliminate feces, dilute intestinal poisons, etc., but also achieve the purpose of reducing body temperature by perfusing low-temperature liquid. With the continuous progress of medical technology, the indwelling continuous enema tube, as a new type of enema device, gradually shows its unique advantages in reducing the core body temperature.

[0018] Enema is a medical operation in which a catheter is inserted from the patient's anus through the rectum into the colon, and then liquid is perfused into the body. Its main purposes include defecation and exhaust, promoting intestinal peristalsis, softening and removing feces, reducing body temperature, inducing labor or diluting intestinal poisons, etc. In addition, enema can also play roles such as supplying drugs, nutrients and water.

[0019] According to the different purposes and operation methods of enemas, enema techniques can be divided into various types, such as large-volume retention enema, small-volume retention enema, retention enema, cleansing enema, etc. Among them, retention enema is to inject a drug solution into the intestine through enema, so that the drug remains in the intestine for a period of time to achieve the therapeutic purpose. In terms of reducing core body temperature, the retention enema method is usually adopted, and the patient's body temperature is reduced by perfusing low-temperature liquid.

[0020] The operation of enema technique needs to be carried out strictly according to certain steps to ensure the safety and effectiveness of the operation. Generally speaking, before enema operation, it is necessary to evaluate the patient's vital signs, defecation situation and the location of the lesion, and determine the patient's lying position and the depth of inserting the anal tube according to the purpose of enema and the location of the lesion. During the operation, necessary items need to be carried, such as enema solution, anal tube, lubricant, cotton swabs, etc., and ensure that the temperature of the enema solution is appropriate. When inserting the anal tube, the front end of the anal tube needs to be lubricated to reduce the resistance during intubation and the irritation to the mucosa. When perfusing the liquid, the medicinal liquid needs to be injected slowly and pay attention to the patient's reaction at any time. After perfusion is completed, the patient needs to clamp the anal tube, and then the anal tube is pulled out and placed in a kidney basin. After the enema is over, the patient needs to lie flat for a period of time before defecating.

[0021] Enema for reducing fever is to inject a drug solution into the intestine and use its cooling effect to reduce body temperature. After the drug is absorbed through the rectal mucosa, it directly enters the blood circulation system, avoiding the first-pass effect of the liver that oral drugs may experience, so that the effect of reducing fever can be achieved faster. In addition, for some patients who cannot take oral drugs or have poor absorption of oral drugs, enema for reducing fever provides another treatment approach.

[0022] (2) Operation method of enema for cooling

[0023] When performing enema for cooling, it is necessary to select an appropriate enema solution and temperature. Generally speaking, the enema solution can be selected as normal saline, warm boiled water, etc., and the temperature should be controlled within an appropriate range. For example, the temperature of the enema solution for adults is generally 38 - 41 °C, for children it is 38 - 40 °C, and a low-temperature solution of 4 °C can be used in case of heat stroke. During the operation, the patient needs to be placed in the left lateral position, insert the anal tube to an appropriate depth, and then slowly inject the enema solution. After injection is completed, the patient needs to clamp the anal tube and keep it for a period of time before pulling it out.

[0024] (3) Effects and precautions of enema for cooling

[0025] Enema cooling can effectively reduce the patient's body temperature and relieve fever symptoms. However, it should be noted that enema cooling also has certain risks and precautions. For example, during the perfusion process, the patient's reaction needs to be closely observed. If discomfort symptoms such as abdominal pain and abdominal distension occur, the perfusion should be stopped immediately. In addition, the temperature and perfusion rate of the enema solution also need to be strictly controlled to avoid unnecessary harm to the patient.

[0026] Design and Materials of Indwelling Continuous Enema Tube

[0027] The design of the indwelling continuous enema tube needs to consider the comfort and safety of the patient. Generally speaking, the indwelling continuous enema tube should be made of soft and smooth materials to reduce the irritation and damage to the patient's intestine. At the same time, the structure of the indwelling continuous enema tube should be reasonable, which is convenient for insertion and fixation to ensure the accuracy and stability of perfusion.

[0028] (2) Application Research of Indwelling Continuous Enema Tube in Reducing Core Body Temperature

[0029] In recent years, more and more studies have begun to focus on the application of indwelling continuous enema tube in reducing core body temperature. Some studies have shown that the indwelling continuous enema tube can effectively reduce the patient's core body temperature, and the cooling effect is stable and lasting. Compared with the traditional enema method, the indwelling continuous enema tube has the advantages of simple operation and high patient comfort.

[0030] (3) Clinical Trials and Safety Evaluation of Indwelling Continuous Enema Tube

[0031] In order to verify the safety and effectiveness of the indwelling continuous enema tube, some research institutions have carried out relevant clinical trials. The results of these trials show that the indwelling continuous enema tube has good safety and effectiveness in reducing core body temperature. However, some potential risks and complications need to be noted during the use process, such as intestinal infection and anal tube detachment. Therefore, when using the indwelling continuous enema tube, it is necessary to strictly master the indications and contraindications and strengthen the monitoring and care of the patient.

[0032] Although the indwelling continuous enema tube has shown certain advantages in reducing core body temperature, there are still some problems and challenges in the existing technology.

[0033] (1) Perfusion Pressure Control Problem

[0034] During the indwelling continuous enema process, the control of perfusion pressure is a key issue. If the perfusion pressure is too high, it may cause intestinal damage or drug extravasation; if the perfusion pressure is too low, it may affect the perfusion effect. At present, although some enema devices are equipped with pressure regulating devices, there are still problems of inaccurate pressure control in actual application.

[0035] (2) Patient Comfort Problem

[0036] The indwelling continuous enema tube needs to be indwelled in the patient's body for a period of time, which may have a certain impact on the patient's comfort. For example, the insertion of the anal tube may cause discomfort or pain to the patient; long-term indwelling may lead to irritation or damage to the intestinal mucosa, etc. Therefore, how to improve the patient's comfort is an important issue that needs to be solved in the technology of indwelling continuous enema tube.

[0037] (III) Infection risk issues

[0038] The use of indwelling continuous enema tube increases the risk of intestinal infection. Since the anal tube communicates with the external environment, if the operation is improper or the nursing is poor, bacteria may enter the intestine and cause infection. Therefore, when using the indwelling continuous enema tube, it is necessary to strictly abide by the principle of aseptic operation and strengthen the nursing and monitoring of the patient.

[0039] (IV) Material and technology innovation needs

[0040] At present, the materials and technologies of indwelling continuous enema tube still need to be further innovated and improved. For example, materials that are softer, smoother, and have better biocompatibility can be developed to make indwelling continuous enema tubes; more intelligent and precise perfusion systems can be developed to control the perfusion pressure and speed, etc.

[0041] In response to the problems and challenges existing in the existing technology, the future development of indwelling continuous enema tube technology can be prospected from the following aspects:

[0042] (I) Material innovation

[0043] Develop materials that are softer, smoother, and have better biocompatibility to make indwelling continuous enema tubes, so as to reduce the irritation and damage to the patient's intestine. At the same time, materials with antibacterial, anti-inflammatory and other functions can be considered for research and development to reduce the infection risk.

[0044] (II) Technology innovation

[0045] Develop a more intelligent and precise perfusion system to control the perfusion pressure and speed. For example, sensor technology can be used to monitor the pressure and temperature changes in the intestine in real time and automatically adjust the perfusion parameters as needed. In addition, wireless transmission technology can be considered for development to achieve remote monitoring and management.

[0046] (III) Expansion of clinical applications

[0047] Further expand the clinical application scope of indwelling continuous enema tube. In addition to reducing the core body temperature, its application potential in the treatment of other diseases, such as intestinal inflammation, constipation, etc., can also be explored.

[0048] (IV) Multidisciplinary cooperation

[0049] Strengthen the cooperation and communication among multiple disciplines such as medicine, materials science, and engineering to jointly promote the development and innovation of the technology of indwelling continuous enema tubes. Through interdisciplinary cooperation, the superior resources of all parties can be integrated to accelerate the research, development, and application of new technologies.
