Description

Technical Field

[0001] The present invention relates to the technical field of enema, and more particularly to an improved enema. Background Art

[0002] In the existing enema technology in the medical and health care fields, traditional enema devices have design defects, especially the imperfect enema liquid reflux prevention and control system. After the operator completes the enema liquid injection, the existing equipment generally lacks an immediate and efficient reflux blocking mechanism, resulting in inevitable backflow of the enema liquid and intestinal contents under the action of the pressure difference. This reflux is not just a small amount of leakage, but due to the reaction lag of the traditional structure, liquid backflow often occurs. What is more troublesome is that the sealing structure of many enema devices adopts the passive sealing principle, that is, the pressure of the reflux liquid is required to activate the sealing mechanism. This "backflow first, then seal" working mode makes reflux an inevitable part of the sealing process, and fundamentally cannot achieve true reflux prevention. This type of design not only reduces the effectiveness of enema treatment, but more seriously, it violates the basic safety concept of modern medical device design, that is, the preventive design principle of preventing problems before they occur.

[0003] The consequences of this design flaw go far beyond reduced treatment efficacy and are more directly related to the health and safety of patients and environmental hygiene. When the enema fluid refluxes, it will first lead to partial loss of the injected medicine or cleaning fluid, reducing the treatment effect; secondly, the refluxed fluid will carry various pathogenic microorganisms and harmful substances in the intestines, contaminating the internal and external environment of the enema equipment, and becoming a potential source of risk for nosocomial cross-infection; for medical staff, handling these contaminated equipment and possible splashing of refluxed fluid increases the risk of infection. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In view of the problems existing in the prior art, the present invention provides an improved enema to solve the technical problems mentioned in the background technology.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an improved enema device, comprising a water pipe; further comprising a non-return mechanism, wherein the non-return mechanism comprises a tail pipe connected to the water pipe and a head pipe arranged coaxially, the tail pipe being connected and installed with two double-sided pipes, the two double-sided pipes being respectively installed with a baffle pipe, the two baffle pipes being respectively connected to the head pipe, a sealing pipe being coaxially installed on the head pipe, a piston disc being sealingly and slidingly connected in the sealing pipe, an intermediate pipe being coaxially installed on the piston disc, a one-way block being installed at the other end of the intermediate pipe, a one-way disc being coaxially installed in the tail pipe, the one-way block being affixed to the one-way disc; further comprising a variable resistance mechanism, the variable resistance mechanism comprising a threaded sleeve connected and installed on the tail pipe, a threaded pipe being threadedly installed in the threaded sleeve, a variable resistance tube being coaxially installed on the threaded tube, and the variable resistance tube being affixed to the two double-sided pipes.

[0008] Preferably, a through-disc is coaxially mounted in the tail tube, the through-disc connects the two ends of the tail tube, a guide tube is coaxially mounted on the through-disc, a guide rod is mounted on the one-way block, and the guide rod is slidably connected in the guide tube. This design constitutes a movement guide for the enema. The through-disc serves as a connecting element in the tail tube to ensure smooth liquid circulation and provides a stable platform for installing the guide tube.

[0009] Preferably, an anal tube is detachably mounted on the head tube, a push plate is sleeved on the outer wall of the anal tube, a nozzle is mounted on the anal tube, and the nozzle is connected to the tail tube. This combined design realizes a multifunctional output system of the enema, and the detachable anal tube is convenient for cleaning, disinfection and replacement to adapt to the needs of different patients.

[0010] Preferably, a plurality of reflux holes are provided at equal intervals on the anal canal, and the plurality of reflux holes are respectively connected to the push plate, and a water outlet is installed on the push plate, and the water outlet is connected to an external collection device. This drainage system design solves the problem of reflux liquid treatment of traditional enema devices. The reflux holes distributed at equal intervals can collect the enema liquid that may overflow in all directions; the connecting channel in the push plate collects these liquids and guides them to the water outlet; the connection between the water outlet and the external collection device realizes the closed collection and treatment of the reflux liquid.

[0011] Preferably, a buffer tube is installed on the water pipe, the other end of the buffer tube is connected to the water bag, and the water bag is hung on an external rack. This liquid supply system design uses the principle of gravity to achieve stable and reliable liquid transportation.

[0012] Preferably, the variable resistance mechanism also includes a spring installed on the threaded sleeve, the spring is sleeved on the threaded tube, a rotating disk is coaxially installed on the threaded tube, and the other end of the spring abuts against the rotating disk. This elastic locking design ensures the accuracy and stability of the flow rate regulation system. The spring forms a continuous axial pressure between the threaded sleeve and the rotating disk, so that the threaded tube and the threaded sleeve maintain a stable meshing and sealing state.

[0013] Preferably, an inner tube is coaxially installed on the side of the threaded tube away from the variable resistance tube, an outer tube is coaxially installed on the sealing tube, the inner tube is slidably connected in the outer tube, and the inner tube is slidably connected in the piston disk. This coaxial connection system realizes the coordination between the variable resistance mechanism and the check mechanism. The sliding connection between the inner tube and the outer tube ensures that the two mechanisms remain coaxial and stable in relative position during movement.

[0014] Preferably, a through hole is coaxially opened in the threaded tube, and the intermediate tube is slidably connected in the through hole. This through-hole design ensures the precise guidance and effective movement of the core components of the check mechanism. The through hole serves as a precise guide channel to limit the movement trajectory of the intermediate tube, ensuring that it can move in a straight line without deviation under the action of pressure.

[0015] Preferably, a limiting ring is installed on the side of the sealing tube away from the outer tube, and the limiting ring and the outer tube are slidingly connected to the piston disc. This double limiting design constructs precise motion control of the piston disc. The limiting ring and the outer tube form a closed activity space, which limits the maximum motion range of the piston disc to prevent it from excessive displacement.

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the present invention provides an improved enema device with the following beneficial effects:

[0018] This improved enema device solves the problem of backflow contamination in traditional enema equipment through a non-return mechanism. Its core innovation lies in the use of a "pre-sealed anti-backflow system", which is composed of components such as a tail tube, a head tube, double-sided tubes and a deflection tube. When the enema liquid is injected, once reflux pressure is generated in the patient's body, this pressure will first be transmitted to the piston disk through the head tube, immediately triggering the piston disk to move upward, so that the one-way block and the one-way disk fit tightly together to form a completely sealed barrier. The uniqueness of this design is that the activation of the anti-backflow system is triggered by the reflux pressure itself, but the seal is formed very early, occurring before the reflux liquid actually flows back. More importantly, even if a very small amount of reflux occurs, what flows into the deflection tube and double-sided tube is only the clean water originally remaining in the pipeline, rather than the contaminated intestinal contents. This water will be pushed to the connection between the one-way block and the one-way disk, forming an additional liquid sealing layer.

[0019] Due to the geometric design angles of the double-sided tubes and the deflector, the pressure generated by the backflow will first act on the piston disk, causing the sealing system to activate one step faster than the backflow liquid. This "pressure first, liquid later" working principle ensures that an irreversible sealing barrier is established before the backflow liquid reaches the critical part. Moreover, even in the most extreme cases, the backflow liquid can only reach the initial part of the deflector tube at most, and cannot enter the main area of ​​the double-sided tube at all, let alone contaminate the tail tube and the water pipe system connected to it. This design not only fundamentally avoids backflow contamination, but also eliminates the design defect of traditional enema devices that must rely on backflow liquid to trigger the seal through structural optimization, thus achieving true preventive protection.

[0020] The improved enema device has a control capability through a variable resistance mechanism. The mechanism consists of a threaded sleeve, a threaded tube, a variable resistance tube and a rotating disk, forming a complete flow rate regulation system. By simply turning the rotating disk, the operator can accurately control the position of the threaded tube, thereby changing the pressure of the variable resistance tube on the bilateral tubes, and realizing stepless regulation of the enema liquid flow rate. The excellence of this design is that it completely gives medical staff or users the right to precisely control the flow rate, and the enema speed can be tailored according to the patient's specific situation, treatment requirements or comfort.

[0021] In clinical applications, the value of this improved enema is not only reflected in improving treatment effects and reducing infection risks, but also in comprehensively improving the doctor-patient experience. For medical staff, it reduces the risk and workload of handling contaminated equipment; for patients, it provides a safer and more comfortable treatment process; for medical institutions, it reduces the risk of cross-infection and resource consumption. This multi-dimensional value creation makes the improved enema a far-reaching technological innovation in the field of digestive system treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] See also Figures 1 to 9, an improved enema, comprising a water pipe 11; further comprising a non-return mechanism, the non-return mechanism comprising a tail pipe 21 connected to the water pipe 11 and a head pipe 22 arranged coaxially, two double-sided pipes 23 being connected and installed on the tail pipe 21, the two double-sided pipes 23 being respectively installed with a baffle pipe 24, the two baffle pipes 24 being respectively connected to the head pipe 22, a sealing pipe 25 being coaxially installed on the head pipe 22, a piston disc 26 being sealingly and slidingly connected in the sealing pipe 25, an intermediate pipe 27 being coaxially installed on the piston disc 26, a one-way block 28 being installed at the other end of the intermediate pipe 27, a one-way disc 29 being coaxially installed in the tail pipe 21, the one-way block 28 being fitted on the one-way disc 29, a through disc 210 being coaxially installed in the tail pipe 21, the through disc 210 being connected to the tail pipe 21 At both ends, a guide tube 211 is coaxially installed on the through-plate 210, a guide rod 212 is installed on the one-way block 28, and the guide rod 212 is slidably connected in the guide tube 211. An anal tube 213 is detachably installed on the head tube 22, and a push plate 214 is sleeved on the outer wall of the anal tube 213. A nozzle 215 is installed on the anal tube 213, and the nozzle 215 is connected to the tail tube 21. A plurality of reflux holes 216 are evenly spaced on the anal tube 213, and the plurality of reflux holes 216 are respectively connected to the push plate 214. A water outlet head 217 is installed on the push plate 214, and the water outlet head 217 is connected to the external collection equipment. A buffer tube 218 is installed on the water pipe 11, and the other end of the buffer tube 218 is connected to the water bag 219, and the water bag 219 is hung on the external rack.

[0036] When performing enema on a patient, the anal tube 213 is first inserted into the anus. Since the diameter of the anal tube 213 is larger than the diameter of the nozzle 215, the sealed connection between the anal tube 213 and the anus is ensured. Since the water bag 219 is hung on the hanger, the horizontal position of the water bag 219 is higher than that of the nozzle 215. Under the action of gravity, the water in the water bag 219 flows along the buffer tube 218 into the water pipe 11, and the water pipe 11 flows into the tail pipe 21. Due to the one-way block 28 and the one-way disk 2 9 is in the fitted state and there is no additional force to fix it, so the seal between the one-way block 28 and the one-way disk 29 can be easily released, and then the water flows into the double-sided tubes 23 at both ends, flows into the head tube 22 through the double-sided tubes 23, and then flows into the nozzle 215 through the head tube 22. The enema process is carried out through the nozzle 215. Since the water outlet head 217 is connected to the external collection device, the water outlet head 217 can discharge the water only when the collection device is turned on, thus completing the enema process.

[0037] After the enema is completed, since there is still enema liquid in the patient's body, the pressure of the enema liquid increases and a backflow process occurs. Since the double-sided tubes 23 are connected through the baffle tubes 24, and the water remaining in the double-sided tubes 23 and the baffle tubes 24 has not been contaminated, the pressurized enema liquid will flow toward the sealing tube 25. Since the two baffle tubes 24 are at an angle, the pressure will first impact the piston disk 26, and then flow into the baffle tube 24 to flow back toward the double-sided tube 23. When the enema liquid is pressed on the piston disk 26, the active The plug disc 26 will be pushed so that the one-way block 28 fits on the one-way disc 29. Then, the enema liquid pushes the uncontaminated water in the double-sided tubes 23 to rush onto the one-way block 28. Since the one-way block 28 and the one-way disc 29 are in a one-way closed state, they are closed to produce a non-return process. Since the enema liquid in the double-sided tubes 23 is still in the position of the deflector tube 24, the water in the double-sided tubes 23 has not been completely discharged and has been blocked. At this time, only a small part of the uncontaminated water in the double-sided tubes 23 flows back into the tail tube 21, thereby ensuring that there will be no backflow and contamination.

[0038] The variable resistance mechanism includes a threaded sleeve 31 connected to the tail tube 21, a threaded tube 32 is installed on the inner thread of the threaded sleeve 31, a variable resistance tube 33 is coaxially installed on the threaded tube 32, and the variable resistance tube 33 is fitted on the two double-sided tubes 23. The variable resistance mechanism also includes a spring 34 installed on the threaded sleeve 31, the spring 34 is sleeved on the threaded tube 32, and a rotating disk 35 is coaxially installed on the threaded tube 32. The other end of the spring 34 contacts the rotating disk 35, and the threaded tube 32 is far away. An embedded tube 36 is coaxially installed on one side of the varistor 33, and an outer tube 37 is coaxially installed on the sealing tube 25. The embedded tube 36 is slidably connected in the outer tube 37, and the embedded tube 36 is slidably connected in the piston disk 26. A through hole 38 is coaxially opened in the threaded tube 32, and the intermediate tube 27 is slidably connected in the through hole 38. A limiting ring 39 is installed on the side of the sealing tube 25 away from the outer tube 37, and the piston disk 26 is limitedly slidably connected between the limiting ring 39 and the outer tube 37.

[0039] When the discharge speed needs to be adjusted, first rotate the rotating disk 35. Since the threaded tube 32 is threadedly connected to the threaded sleeve 31, the position of the threaded tube 32 will be changed. Since the variable resistance tube 33 is installed on the threaded tube 32, the position of the variable resistance tube 33 will be changed as the threaded tube 32 moves. Then the variable resistance tube 33 will fit on the two double-sided tubes 23, thereby changing the opening degree of the two double-sided tubes 23. When the opening degree is large, the flow is fast, and when the opening degree is small, the flow is slow, so the flow rate can be adjusted. Since the spring 34 respectively contacts between the threaded sleeve 31 and the rotating disk 35, a sealed state will be generated no matter which position the threaded tube 32 is rotated to, thereby ensuring the sealing effect. Since the other end of the threaded tube 32 is installed with an embedded tube 36, and the embedded tube 36 is slidably connected to the outer tube 37, the sealing effect is guaranteed.

[0040] In all the schemes mentioned above, the connection between the two parts can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be described here one by one. In the above, all fixed connections are preferably considered to be welding. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
