Description

Technical Field

[0001] The invention relates to the technical field of retention enema, in particular to a retention enema device. Background Art

[0002] Retention enema is a common clinical operation method in which liquid medicine is poured into the rectum or colon and retained for a certain period of time, and absorbed through the intestinal mucosa to achieve the therapeutic purpose. For example, in chronic colitis, ulcerative colitis, etc., the drug is directly poured into the intestine so that the drug is in full contact with the lesion site, which can play an anti-inflammatory, astringent, hemostatic and other effects, and promote the repair and healing of the intestinal mucosa. For some patients with mental tension, insomnia, etc., sedatives and hypnotic drugs can be given through retention enema, so that the drugs are absorbed through the intestinal mucosa, exerting a sedative and hypnotic effect, helping patients relieve tension and improve sleep quality. Before enema, prepare the enema solution according to the doctor's instructions. Generally, 10% chloral hydrate is used for sedation and hypnosis; 2% berberine, 0.5%~1% neomycin or other antibiotics are used for intestinal anti-infection.

[0003] The temperature of enema solution is generally around 38°C. Too high or too low a temperature will irritate the intestines. The concentration and dosage of enema solution should be strictly followed according to the doctor's instructions based on the patient's condition and age.

[0004] When inserting the anal canal, the action should be gentle to avoid damaging the anal and rectal mucosa. If there is resistance or the patient feels pain or other discomfort, the insertion should be stopped and the cause should be found before continuing the operation;

[0005] During the enema process, the patient's complexion, expression, vital signs and other changes should be closely observed. If any abnormality is found, the enema should be stopped immediately and appropriate measures should be taken;

[0006] Retention enema is generally contraindicated for patients with injuries, inflammation or surgery to the anus, rectum, colon, etc., as well as pregnant women and patients with severe heart failure.

[0007] Traditional retention enema devices cannot guarantee the infusion of drug solution and the corresponding regulation of the drug infusion speed in combination with the patient's treatment situation, and the comfort of intubation and the accuracy of drug delivery to the lesion site. At the same time, because bladder irrigation and drug administration are similar to anal drug administration, the present device can address the factor that bladder irrigation and drug administration cannot be used in combination with anal drug administration. Therefore, the present device provides a retention enema device. Summary of the invention

[0008] The embodiment of the present invention provides a retention enema device to solve the above-mentioned technical problems.

[0009] The embodiment of the present invention adopts the following technical scheme: including a three-lumen catheter for being inserted into the anus for flushing, draining urine and delivering drugs, an airbag device for preventing urine from flowing out and being fixed to the anus, a drug treatment device for delivering drugs for treatment, a speed regulating device for controlling the flow rate of the drug solution during the drug delivery treatment process, and a sealing cap for sealing the end of the three-lumen catheter. The airbag device is sleeved on the outside of the three-lumen catheter and is located close to the head end of the three-lumen catheter.

[0011] Furthermore, the interior of the middle urinary tube is connected to the urinary tube nozzle, and the middle urinary tube is provided with an inner passage connected to the outer passage.

[0012] Furthermore, the terminal urinary catheter includes an auxiliary pipeline, a drainage pipeline and a drug administration and flushing pipeline. The auxiliary pipeline and the drainage pipeline are connected to the inner layer passage, and the drug administration and flushing pipeline is connected to the inside of the middle urinary catheter.

[0013] Furthermore, the airbag device includes a limiting airbag, a drainage cavity, an airbag passage and a passage cap. The drainage cavity is sleeved on the outside of the middle urinary catheter near the position of the head end urinary catheter. The drainage cavity is connected to the inner layer passage on the middle urinary catheter. A plurality of waste liquid holes are arranged around the middle urinary catheter, and the plurality of waste liquid holes are connected to the drainage cavity. The limiting airbag is sleeved on the outside of the drainage cavity, and the airbag passage is connected to the limiting airbag. The head end of the airbag passage is connected to the limiting airbag and the end extends from the inner layer passage to the auxiliary pipeline. The passage cap is arranged on the outside of the auxiliary pipeline to seal the end of the airbag passage.

[0014] Furthermore, the drainage cavity is provided by a soft film, and the limiting airbag is expanded by inflation or water injection.

[0015] Furthermore, the drug treatment device includes an auxiliary tube, a syringe, a connecting tube and an enema bag. The auxiliary tube is sleeved on the end of the medication flushing pipeline. The syringe and the auxiliary tube are in an adaptive connection state. The connecting tube can be inserted into the end of the medication flushing pipeline for communication. The connecting tube can be connected to the enema bag through a puncture needle.

[0016] Furthermore, the several speed regulating devices all include a speed regulating tube, a matching tube and a docking tube. The speed regulating tube and the matching tube are connected, the matching tube and the docking tube are connected, the docking tube and the speed regulating tube are in a matching and sleeve-connected arrangement, and the docking tube and the end of the medication flushing pipeline are in a matching and sleeve-connected arrangement.

[0017] Furthermore, the three-lumen urinary catheter is provided with scale values, and the three-lumen urinary catheter is made of silicone material.

[0018] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0019] First, the three-lumen urinary catheter can be used to flush the patient's bladder, drain and collect urine in the bladder, deliver drugs to the bladder by injection and infusion, and inject drugs into the rectum or colon through the patient's anus for absorption by the intestinal mucosa to achieve the purpose of treatment. In addition, during the drug delivery process, the drug delivery speed can be adjusted accordingly according to the type of drug used and the patient's treatment condition, so as to facilitate the patient's drug treatment operation;

[0020] The principle of inserting the device into the patient's bladder through a three-lumen urinary catheter and the flushing and medication operation is the same as the principle of inserting the device into the patient's anus through a three-lumen urinary catheter to reach the required treatment position. The operation process is also the same, except that the main operations are performed according to the treatment specifications.

[0021] Secondly, the conical setting of the catheter head and the blunt head at the front end can facilitate the insertion of the three-lumen catheter into the patient's bladder for treatment while reducing pain. During the process of flushing the patient's bladder and administering medicine to the patient, the medicine and flushing water are ultimately discharged from the through holes on the catheter nozzle in the inner passage. The conical setting of the catheter head can also reduce the conflict between sewage entering the catheter head and the flushing water and medicine flowing inside the middle catheter. Even if the flushing water and medicine enter the inner passage, they will flow into the inner passage of the middle catheter through several drainage holes and finally flow into the urine collection bag for collection.

[0022] Thirdly, after the three-lumen urinary catheter is inserted into the bladder, in order to limit and fix the urinary catheter, the limiting airbag is expanded by inflating or injecting water through the airbag tube, so that the limiting airbag forms a closed barrier at the neck of the bladder to limit the urinary catheter, so as to facilitate the replacement of the three-lumen urinary catheter for treatment. After the limiting airbag is inflated or injected with water, the airbag tube can be blocked by the tube cap. After the limiting airbag forms a closed barrier at the neck of the bladder, during the process of flushing the bladder through the three-lumen urinary catheter, the flushing water enters the middle urinary catheter from the terminal urinary catheter and is finally discharged from the several through holes on the urinary catheter nozzle in the head end urinary catheter to flush the bladder. However, due to some factors, urine and sewage will leak out of the body. The limiting air bag can block urine and sewage, and make them flow into the drainage cavity, and then flow from the drainage cavity into the inner layer of the middle urethra, and finally be discharged through the auxiliary pipeline. At this time, the urine collecting bag can be connected to the auxiliary pipeline, so that it flows into the urine collecting bag for storage, avoiding the accumulation of urine and sewage in the patient's bladder and urethra to form blockage and cause pain to the patient. At the same time, it also avoids contamination. It can effectively improve the efficiency and cleanliness of urine drainage, keep the perineum dry, reduce the risk of urinary tract infection, significantly improve the patient's care quality and quality of life, reduce the irritation and damage to the skin caused by urine leakage, and reduce the incidence of complications such as bedsores.

[0023] Fourthly, when a three-lumen urinary catheter is inserted into the patient's anus for drug administration, the principle is the same as that of intravesical drug administration. First, the three-lumen urinary catheter is inserted into the desired drug administration position of the patient's anus. The required movement position can be determined according to the scale value on the three-lumen urinary catheter. Then, after the syringe is used to extract the appropriate potassium solution drug, the syringe is connected to the drug administration flushing pipeline, and the drug is delivered to the desired treatment position by injection of the syringe, thereby realizing the drug delivery from the anus for patient treatment. The intestine has a huge absorption area and a rich capillary network. Potassium ions can enter the blood circulation through the intestinal mucosal epithelial cells, thereby achieving the purpose of supplementing potassium ions. By injecting potassium solution through the anus, the good absorption function of the intestine can be utilized to enable potassium ions to be absorbed more effectively to correct the low potassium state in the body. Compared with intravenous potassium supplementation, after the potassium solution is injected into the anus, the absorption of potassium ions is relatively slow and continuous, and a relatively stable blood potassium concentration can be maintained for a certain period of time. For some patients who do not need to quickly increase the blood potassium level or cannot tolerate rapid potassium supplementation, it is a more suitable potassium supplementation method, which can reduce the risks of hyperkalemia and other risks that may be caused by rapid potassium supplementation.

[0024] Fifth, after the required therapeutic drugs are injected into the enema bag, the three-lumen catheter is first inserted into the required drug administration position of the patient's anus. The required movement position can be determined according to the scale value on the three-lumen catheter, thereby realizing the slow delivery of drugs for treatment through the enema bag. In the process of infusion treatment through the enema bag, the head end can be connected to the drug administration flushing pipeline through a number of corresponding connection devices, and the end can be connected to the connecting pipe. The end of the connecting pipe is provided with a puncture needle, which is punctured into the enema bag. At this time, the drug inside the enema bag first enters the corresponding speed regulating device through the connecting pipe, and then flows into the three-lumen catheter. Through the setting of a number of speed regulating devices, Because of its unique one-way conduction characteristic, the liquid can only flow from the enema bag toward the anus without backflow, which prevents feces, bacteria and other pollutants in the intestine from flowing back into the enema bag, avoids contamination of the enema liquid, and thus reduces the risk of complications such as intestinal infections in patients, ensuring the safety and hygiene of enema treatment. It can prevent liquid backflow, so that the liquid in the enema bag can maintain a relatively stable pressure and continuously and steadily inject into the intestine, which helps the enema liquid to enter the intestine more evenly and smoothly, avoiding the adverse effects of pressure fluctuations caused by liquid reflux on the intestinal mucosa, and at the same time ensures that the enema liquid reaches an effective therapeutic concentration and distribution in the intestine.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0039] The embodiment of the present invention provides a retention enema device, comprising a three-lumen urinary catheter 1 for being inserted into the anus for flushing, draining urine and delivering drugs, an air bag device 2 for preventing urine from flowing out and fixed to the anus, a drug treatment device 3 for delivering drugs for treatment, a speed regulating device 4 for controlling the flow speed of the drug solution during the drug delivery treatment process, and a sealing cap 5 for blocking the end of the three-lumen urinary catheter 1, wherein the air bag device 2 is sleeved on the outside of the three-lumen urinary catheter 1 and is located close to the head end of the three-lumen urinary catheter 1, the drug treatment device 3 is connected to the end of the three-lumen urinary catheter 1, and the drug treatment device 3 can also be connected to the end of the three-lumen urinary catheter 1 by the speed regulating device 4, the sealing cap 5 is arranged at the end of the three-lumen urinary catheter 1, and the speed regulating device 4 is provided in plurality, and the plurality of speed regulating devices 4 are sleeved and connected one by one;

[0040] The device can flush the patient's bladder through a three-lumen urinary catheter 1, can drain and collect urine inside the bladder, can deliver drugs to the bladder through injection and infusion, can also inject drugs into the rectum or colon through the patient's anus for absorption through the intestinal mucosa to achieve the purpose of treatment, and during the drug delivery process, the drug delivery speed can be adjusted accordingly according to the type of drug used and the patient's treatment condition, so as to facilitate the patient's drug treatment operation.

[0041] The principle of inserting the device into the patient's bladder through a three-lumen urinary catheter 1 and the flushing and medication operation is the same as that of inserting the device into the patient's anus through a three-lumen urinary catheter 1 to reach the required treatment position. The operation process is also the same, except that the main operations are performed according to the treatment specifications.

[0042] Preferably, the three-lumen urinary catheter 1 comprises a head urinary catheter 11, a middle urinary catheter 12 and a terminal urinary catheter 13, wherein the head urinary catheter 11, the middle urinary catheter 12 and the terminal urinary catheter 13 are connected, the head urinary catheter 11 comprises a urinary catheter head 111 and a urinary catheter nozzle 112, the urinary catheter head 111 is conical, the head end of the urinary catheter head 111 is blunt, the interior of the urinary catheter head 111 is divided into an inner passage 113 and an outer passage 114, the inner passage 113 is surrounded by a plurality of drainage holes 115 and the plurality of drainage holes 115 are connected to the outer passage 114, the The urinary catheter nozzle 112 is located inside the inner passage 113 of the urinary catheter nozzle 111. The urinary catheter nozzle 112 is provided with a plurality of through holes 116. The interior of the middle urinary catheter 12 is connected to the urinary catheter nozzle 112. The middle urinary catheter 12 is provided with an inner layer passage 121 connected to the outer passage 114. The terminal urinary catheter 13 includes an auxiliary pipeline 131, a drainage pipeline 132 and a medication flushing pipeline 133. The auxiliary pipeline 131 and the drainage pipeline 132 are connected to the inner layer passage 121, and the medication flushing pipeline 133 is connected to the interior of the middle urinary catheter 12.

[0043] The conical setting of the catheter head 111 and the blunt head at the front end can facilitate the insertion of the three-chamber catheter 1 into the bladder of the patient for treatment while reducing pain. In the process of flushing the patient's bladder and administering medicine to the patient, the medicine and flushing water are finally discharged from the through hole 116 on the catheter nozzle 112 located in the inner passage 113. The conical setting of the catheter head 111 can also reduce the conflict between sewage entering the catheter head 111 and the flushing water and medicine flowing inside the middle urinary catheter 12. Even if the flushing water and medicine enter the inner passage 113, they will flow into the inner passage 121 of the middle urinary catheter 12 through the plurality of drainage holes 115, and finally flow into the urine collection bag for collection.

[0044] Due to various reasons, such as prostate hyperplasia, urethral stenosis, neurogenic bladder, etc., the patient cannot discharge urine normally. At this time, by inserting the three-chamber urinary catheter 1 into the bladder and connecting the drainage bag to the drainage pipeline 132 in the three-chamber urinary catheter 1, the urine in the bladder can be drained out, which can quickly relieve the patient's lower abdominal distension and pain and other discomfort symptoms, reduce bladder pressure, protect kidney function, and after drainage to the urine bag, it is convenient for medical staff to regularly observe and record urine volume, providing an important basis for disease diagnosis and adjustment of treatment plans;

[0045] Since patients have long-term indwelling triple-lumen catheterization, sediments and bacteria in urine are easily accumulated in the bladder, causing urinary system infection. After the flushing water is extracted by the syringe 32 and connected to the drug administration flushing pipeline 133, the bladder can be flushed by injection through the syringe 32. The flushing water inside the syringe 32 will enter the middle urinary catheter 12 from the terminal urinary catheter 13 and finally be discharged and flushed from the head end urinary catheter 11, which can timely remove bacteria, inflammatory exudates and other impurities in the bladder, keep the bladder clean, and reduce the incidence of infection. For example, when patients with neurogenic bladder have long-term indwelling catheterization, bladder flushing is one of the important measures to prevent infection. After urinary system surgeries such as electroresection of prostate hyperplasia and electroresection of bladder tumors, there may be a small amount of bleeding in the bladder. After the blood coagulates, blood clots are formed, which are easy to block the catheter and affect urine drainage. At this time, the three-lumen urinary catheter 1 can also be used for continuous or intermittent bladder flushing, which can flush out the blood clots in the bladder in time, keep the urinary tract unobstructed, and promote postoperative recovery.

[0046] Due to certain bladder diseases, such as interstitial cystitis, bladder mucosal leukoplakia, etc., local drug administration treatment is required in the bladder. After the required therapeutic drug is extracted through the syringe 32 and connected to the drug administration flushing pipeline 133, the bladder drug administration treatment can be performed by injection through the syringe 32. The drug is injected into the bladder so that the drug is in full contact with the lesion site in the bladder, thereby improving the therapeutic effect of the drug and reducing the adverse reactions of systemic medication. For example, the use of BCG instillation to treat bladder carcinoma in situ is to inject BCG into the bladder through the three-lumen urinary catheter 1 for immunotherapy.

[0047] Preferably, the airbag device 2 comprises a limiting airbag 21, a drainage cavity 22, an airbag through tube 23 and a through tube cap 24. The drainage cavity 22 is sleeved on the outside of the middle urinary tube 12 near the position of the head end urinary tube 11. The drainage cavity 22 is connected to the inner layer passage 121 on the middle urinary tube 12. A plurality of waste liquid holes 122 are arranged around the middle urinary tube 12. The plurality of waste liquid holes 122 are connected to the drainage cavity 22. The limiting airbag 21 is sleeved on the outside of the drainage cavity 22. The airbag through tube 23 is connected to the limiting airbag 21. The head end of the airbag through tube 23 is connected to the limiting airbag 21 and the end extends from the inner layer passage 121 into the auxiliary pipeline 131. The through tube cap 24 is arranged on the outside of the auxiliary pipeline 131 to block the end of the airbag through tube 23.

[0048] After the three-lumen urinary catheter 1 is inserted into the bladder, in order to limit and fix the urinary catheter, the limiting airbag 21 is expanded by inflating or injecting water through the airbag tube 23, so that the limiting airbag 21 forms a closed barrier at the neck of the bladder to limit the urinary catheter, so as to facilitate the replacement of the three-lumen urinary catheter 1 for treatment. After the limiting airbag 21 is inflated or injected with water, the airbag tube 23 can be blocked by the tube cap 24. After the limiting airbag 21 forms a closed barrier at the neck of the bladder, during the process of flushing the bladder through the three-lumen urinary catheter 1, the flushing water enters the middle urinary catheter 12 from the end urinary catheter 13 and is finally discharged from the several through holes 116 on the urinary catheter nozzle 112 in the head end urinary catheter 11 to flush the bladder. Due to some factors, urine and sewage will When urine and sewage leak out of the body, the limiting airbag 21 can block them and allow them to flow into the drainage cavity 22, and then flow from the drainage cavity 22 into the inner layer of the middle urinary catheter 12, and finally be discharged through the auxiliary pipeline 131. At this time, the urine collecting bag can be connected to the auxiliary pipeline 131, so that the urine and sewage can flow into the urine collecting bag for storage, thereby avoiding the accumulation of urine and sewage in the patient's bladder and urethra to form blockage and cause pain to the patient. At the same time, it also avoids the occurrence of contamination, which can effectively improve the efficiency and cleanliness of urine drainage, keep the perineum dry, reduce the risk of urinary tract infection, significantly improve the patient's care quality and quality of life, reduce the irritation and damage to the skin caused by urine leakage, and reduce the incidence of complications such as bedsores.

[0049] Preferably, the drainage cavity 22 is provided by a soft film, and the limiting airbag 21 is expanded by inflation or water injection;

[0050] When the limiting airbag 21 is not filled with water or inflated with air, it is convenient for the three-lumen urinary catheter 1 to be inserted into the patient's bladder. The drainage cavity 22 is set as a soft film and is in a relatively close fit with the three-lumen urinary catheter 1. Therefore, the three-lumen urinary catheter 1 will not be blocked too much during the insertion of the patient's bladder. After the limiting airbag 21 is filled with water or inflated with air, the expansion of the limiting airbag 21 will also stretch the drainage cavity 22, so that the drainage cavity 22 forms a space of the required size and is just connected to the inner layer passage 121 on the middle urinary catheter 12, so as to facilitate the outflow and collection of waste liquid.

[0051] Preferably, the drug treatment device 3 includes an auxiliary tube 31, a syringe 32, a connecting tube 33 and an enema bag 34, wherein the auxiliary tube 31 is sleeved at the end of the medication flushing pipeline 133, the syringe 32 and the auxiliary tube 31 are in an adaptive connection state, the connecting tube 33 can be inserted into the end of the medication flushing pipeline 133 for communication, and the connecting tube 33 can be connected to the enema bag 34 through a puncture needle;

[0052] For example, due to oral diseases, gastrointestinal obstruction, anorexia, etc., the patient cannot eat normally for a long time, and the potassium intake in the food is seriously insufficient, which may lead to potassium deficiency in the body. Potassium solution treatment is needed to supplement potassium ions to maintain normal physiological functions of the body. In addition, patients with some chronic wasting diseases such as malignant tumors, chronic kidney disease, chronic diarrhea, etc. are often accompanied by malnutrition, and the intake and absorption of potassium are affected. They are prone to hypokalemia and need to supplement potassium solution in time. For some patients who have difficulty swallowing, gastrointestinal obstruction, etc. who cannot supplement potassium through oral routes, or patients who cannot tolerate oral potassium supplementation due to severe gastrointestinal reactions, it is necessary to inject potassium solution through the anus as a potassium supplementation route instead of a retention enema device to supplement the potassium ions needed by the body. When the three-lumen urinary catheter 1 is inserted into the patient's anus for drug administration, it is the same as the principle of intravesical drug administration. First, the three-lumen urinary catheter 1 is inserted into the patient's anus at the desired drug administration position. The required movement position can be determined according to the scale value on the three-lumen urinary catheter 1. Then, after the syringe 32 extracts the corresponding potassium solution drug, the syringe 32 and the drug administration flushing pipeline are flushed. After the connection of 133, the drug is delivered to the desired treatment position through the injection of the syringe 32, thereby realizing the delivery of the drug from the anus for the treatment of the patient. The intestine has a huge absorption area and a rich capillary network. Potassium ions can enter the blood circulation through the intestinal mucosal epithelial cells, thereby achieving the purpose of supplementing potassium ions. By injecting potassium solution through the anus, the good absorption function of the intestine can be utilized to enable potassium ions to be absorbed more effectively to correct the low potassium state in the body. Compared with intravenous potassium supplementation, after the potassium solution is injected into the anus, the absorption of potassium ions is relatively slow and continuous, and a relatively stable blood potassium concentration can be maintained for a certain period of time. For some patients who do not need to quickly increase the blood potassium level or cannot tolerate rapid potassium supplementation, it is a more suitable potassium supplementation method for retaining the enema device, which can reduce the risk of hyperkalemia and the like caused by rapid potassium supplementation. Of course, here it is only described that the drug required by the patient is a potassium solution, and the device is not limited to the injection treatment of potassium solution. As long as the drug meets the requirements of anal injection treatment, it can be extracted by the syringe 32 and injected into the desired treatment position to treat the patient.

[0053] Preferably, the plurality of speed regulating devices 4 each include a speed regulating tube 41, a matching tube 42 and a butt joint tube 43, the speed regulating tube 41 and the matching tube 42 are connected, the matching tube 42 and the butt joint tube 43 are connected, the butt joint tube 43 and the speed regulating tube 41 are in an adaptable sleeve-connected arrangement, and the butt joint tube 43 and the end of the medication flushing pipeline 133 are in an adaptable sleeve-connected arrangement;

[0054] The flow shape inside the speed regulating device 4 is a complex shape in which multiple forms such as vortex and streamline are intertwined and interact with each other in three-dimensional space, and it will vary according to the specific structural design of the speed regulating device 4, the properties of the fluid, and the boundary conditions of the flow.

[0055] For example, in chronic colitis and ulcerative colitis, the drug is directly injected into the intestine to make the drug fully contact with the lesion site, which can play the role of anti-inflammatory, astringent, hemostatic, etc., and promote the repair and healing of the intestinal mucosa. For some patients with mental tension, insomnia, etc., sedative hypnotic drugs can be given through retention enema, so that the drugs are absorbed through the intestinal mucosa, play a sedative and hypnotic effect, help patients relieve tension, and improve sleep quality. When the patient is given a retention enema, the enema bag 34 is generally injected with the required therapeutic drug, and the enema bag 34 is infused with the required therapeutic drug. This process must be carried out according to the doctor's instructions. Prepare enema solution, explain to the patient the purpose, method, precautions and key points of retention enema, obtain the patient's understanding and cooperation, let the patient defecate or give defecation enema to clean the intestines and facilitate drug absorption, slowly input the drug inside the enema bag 34 to the treatment position to treat the patient, after the required therapeutic drug is injected into the enema bag 34, first insert the three-lumen urinary catheter 1 into the patient's anus to where the drug is required to be administered, and the required movement position can be determined according to the scale value on the three-lumen urinary catheter 1, thereby realizing the slow delivery of drugs through the enema bag 34 for treatment. During the infusion treatment through the enema bag 34, the head end can be connected to the medication flushing pipeline 133 through the corresponding connection of the several speed regulating devices 4, and the end is connected to the connecting tube 33. The end of the connecting tube 33 is provided with a puncture needle, which punctures into the enema bag 34. At this time, the medicine inside the enema bag 34 first enters the corresponding speed regulating device 4 through the connecting tube 33, and then flows into the three-lumen urinary catheter 1. Through the setting of the several speed regulating devices 4, because of the unique one-way conduction characteristics, the liquid can only flow from the enema bag 34 to the anus, and no backflow occurs. This prevents the feces, bacteria and other pollutants in the intestine from flowing back to the enema bag 34, avoids the enema liquid from being contaminated, thereby reducing the risk of complications such as intestinal infection in patients, ensuring the safety and hygiene of enema treatment, and preventing liquid reflux, so that the liquid in the enema bag 34 can maintain a relatively stable pressure and continuously and stably inject into the intestine, which helps the enema liquid to enter the intestine more evenly and smoothly, avoiding the adverse effects of pressure fluctuations caused by liquid reflux on the intestinal mucosa, and also ensuring that the enema liquid reaches an effective therapeutic concentration and distribution in the intestine;

[0056] In actual medical operations such as retention enema, when using the speed regulating device 4, the liquid flow rate is usually controlled within a suitable range, generally ranging from tens of milliliters to hundreds of milliliters per minute, by adjusting the height of the enema bag 34 according to the patient's specific situation and treatment needs. For example, for some patients with more sensitive intestines, the flow rate may be controlled at 30 to 50 milliliters per minute, and for patients with better intestinal tolerance, the flow rate can be appropriately increased to about 100 to 200 milliliters per minute, etc. The number of speed regulating devices 4 and the height of the enema bag 34 are coordinated to determine the vertical flow rate of the liquid within the range of 30 to 50 milliliters per minute. Description of the number of speed regulating devices 4: When the number of speed regulating devices 4 is 2 to 5, the resistance to liquid passage is relatively small. In this case, to achieve a flow rate of 30 to 50 milliliters per minute, the height of the enema bag 34 may be It is relatively low, generally around 30-50 cm, because fewer nodes allow the liquid to pass through the valve more smoothly, and the pressure difference generated by the lower height of the enema bag 34 can meet the corresponding flow rate requirements. When the number of speed regulating devices 4 is 6 to 10, as the number of nodes increases, the resistance to liquid passage will also increase accordingly. At this time, in order to obtain a flow rate of 30 to 50 ml per minute, the height of the enema bag 34 may need to be increased to about 50-80 cm. A medium number of nodes has a certain obstruction to the flow of liquid, and a higher pressure difference is required to push the liquid through the valve to achieve the desired flow rate. When the number of speed regulating devices 4 is 11 to 15, when the number of nodes is large, the resistance to liquid passing through the valve is large. To achieve a flow rate of 30 to 50 ml per minute, the height of the enema bag 34 may need to reach about 80-120 cm. More nodes make the flow path of the liquid in the valve more complicated, requiring a larger pressure difference to overcome resistance and ensure that the liquid passes through at an appropriate flow rate. Therefore, medical staff can combine different numbers of speed regulating devices 4 according to the patient's treatment needs, thereby improving the treatment effect and the diversity of treatment adaptation. In actual applications, to achieve a vertical liquid flow rate of 30 to 50 ml per minute, it is necessary to determine the optimal combination of the number of nodes of the speed regulating device 4 and the height of the enema bag 34 through experiments and actual measurements, and flexibly adjust according to the specific equipment, liquid and patient conditions.
