DETAILED DESCRIPTION

[0019] The embodiments of the present invention are described in detail below. The embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

[0020] See Figure 1 , Figure 2 and Figure 3 A rectal irrigation device of the present invention comprises an excretion tube 1, a three-way pipe joint 2, a drainage tube 3 and an irrigation tube 4. The three interfaces of the three-way pipe joint 2 are respectively connected to the excretion tube 1, the drainage tube 3 and the irrigation tube 4. The excretion tube 1 comprises an inner tube 1-1 and an outer tube 1-2. An air layer 1-3 is formed between the inner tube 1-1 and the outer tube 1-2. A plurality of irrigation tubes 4 cross the air layer 1-3 and are exposed to the air layer 1-3. A plurality of inflation tubes 5 are also arranged in the air layer 1-3. An air bag 7 is arranged on the outer wall of the outer tube 1-2. One end of the inflation tube 5 is connected to the air bag 7. The other end of the inflation tube 5 is connected to the air bag valve 8. The plurality of irrigation tubes 4 and the plurality of inflation tubes 5 are staggered one by one along the circumferential direction of the air layer 1-3. A visible optical fiber 6 is arranged on the inner wall of the inner tube 1-1 and at a position corresponding to the irrigation tube 4. A fiber optic lens is installed on the visible optical fiber 6. Among them, the inflation tube 5 is equipped with a first one-way valve 9 for controlling the airflow from the airbag valve 8 to the airbag 7. The flushing tube 4 is equipped with a second one-way valve 10 for controlling the liquid from the external water source to the patient's rectum. The design of the second one-way valve 10 prevents the excretion liquid from being discharged through the flushing tube 4. A replaceable drainage bag 11 is connected to one end of the drainage tube 3, and a third one-way valve 12 is installed on the drainage tube 3 for controlling the excretion liquid from the patient's rectum to the drainage bag 11. The actual operation of each pipeline is effectively supervised by the cooperation of the visual optical fiber 6 with the first one-way valve 9, the second one-way valve 10 and the third one-way valve 12.

[0021] The radial cross section of the inflated gas tube 5 is an arc-shaped structure, both ends of which are convex surfaces. The end faces of two adjacent gas tubes 5, the interior of the inner tube 1-1 and the outer wall of the outer tube 1-2 perform four-point positioning on the corresponding flushing tube 4. Through the effective arrangement and combination of the gas tube 5 and the flushing tube 4, the flushing tube 4 is limited and controlled to ensure its normal and stable use, thereby improving the overall stability of use.

[0022] The port of the flushing tube 4 exceeds the end face of the excretion tube 1 by 3 to 5 mm. This design facilitates the flushing tube 4 to more conveniently and effectively clean the patient's rectum. The end of the flushing tube 4 is sleeved with a flexible medical silicone sleeve 13. Silicone has good biocompatibility, is non-irritating, non-toxic, and has no allergic reaction to human tissues, has very little body rejection reaction, has good physical and chemical properties, can maintain its original elasticity and softness during contact with body fluids and tissues, and is not degraded. It is a fairly stable inert substance.

[0023] The flushing tube 4 is filled with physiological saline or medical glycerin through the supply of an external water source. The temperature of physiological saline is close to the body temperature of the human body, not too cold or too hot. Physiological saline stimulates intestinal peristalsis, softens and removes feces, and is used to clean the intestines and constipation. Medical glycerin has a hypertonic effect. After entering the rectum, it can absorb moisture in the intestinal wall, increase the moisture in the feces, soften the feces, facilitate the discharge of feces, and relieve constipation symptoms. Medical glycerin produces chemical and physical stimulation to the rectal intestinal wall, stimulates the nerve endings of the intestinal wall, promotes intestinal peristalsis, enhances the propulsive movement of the intestine, and prompts feces to move toward the anus. In addition, medical glycerin can dilute the feces and stagnation in the intestine. Under the action of intestinal peristalsis, the feces, gas accumulation, etc. in the intestine are discharged from the body, so as to achieve the purpose of cleaning the intestine, which is accurate for related examinations or operations, that is, to create conditions for the operation and meet the use requirements.

[0024] The drainage tube 3 is connected to the drainage bag 11 through a dedicated interface, and the port of the drainage tube 3 is a flat port that matches the dedicated interface. Such a design can improve the rapid connection between the drainage tube 3 and the dedicated connector. The drainage bag 11 is a detachable and replaceable structure to meet the use requirements.

[0025] The head of the excretion tube 1 has rounded corners, which provides certain convenience during the process of being introduced into the patient's rectum, while also avoiding trauma to the patient's rectum and causing unnecessary pain to the patient.

[0026] The ends of the inner tube 1-1 and the outer tube 1-2 are provided with detachable annular port covers. The design of the front and rear covers not only ensures that the relative positions of the inner tube 1-1 and the outer tube 1-2 are fixed, but also strengthens the overall structural strength of the discharge tube 1. In addition, the detachable design of the covers not only facilitates the arrangement of the flushing tube 4 and the inflation tube 5, but also facilitates the replacement of the flushing tube 4 and the inflation tube 5.

[0027] The working principle of the rectal flushing device is: first, the front end of the drainage tube 1 is introduced into the patient's rectum, then, the external air source (the air source can be trioxygen) is connected to the airbag valve 8, the airbag 7 is inflated, and the flushing tube 4 is positioned at four points in combination with the inner tube 1-1 and the outer tube 1-2 when the airbag 7 is inflated. Then, the flushing tube 4 is connected to an external water source (physiological saline or medical glycerin, etc.), and the rectal irrigation and cleaning operation is performed on the inside of the patient's rectum through the flushing tube 4. Finally, the excretion liquid will be discharged into the drainage bag 11 through the inner cavity of the inner tube 1-1 of the drainage tube 1.

[0028] The advantages of a rectal irrigation device of the present invention are:

[0029] 1. The actual operation of each pipeline can be effectively supervised by the cooperation of the visual optical fiber 6, the optical fiber lens equipped with the visual optical fiber 6, and the one-way valve, that is, the flushing and specific drainage conditions can be always paid attention to. The flushing, drainage and inflation can be effectively controlled by respectively setting the first one-way valve 9, the second one-way valve 10 and the third one-way valve 13.

[0030] 2. Through the effective arrangement and combination of the inflation tube 5 and the flushing tube 4, the flushing tube 4 is limited and controlled to ensure its normal and stable use and improve the overall stability of use; by adopting the four-point positioning method of the flushing tube 4, it is ensured that the flushing tube 4 will not be displaced or squeezed, thereby ensuring uniform flushing pressure; the traditional flushing tube 4 cannot be effectively limited and fixed, and will bend and deform during the actual flushing process, resulting in uneven flushing. The multi-pipeline structure (several flushing tubes 4) of the present application is adopted, and two adjacent flushing tubes 4 are separated by the inflation tube 5. In this way, during the inflation process, each flushing tube 4 can be separated, limited, stuck and fixed, so as to achieve stable flushing.

[0031] 3. By setting a flexible medical silicone sleeve 13 on the water outlet port of the flushing tube 4, the flexible medical silicone sleeve 13 can avoid secondary damage caused by direct contact with human tissue during the flushing process, and play a good protective role on the patient's rectal area.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
