Description

Technical Field

[0001] This application relates to the field of medical care equipment technology, and in particular to a cavity irrigator for anorectal care. Background Technology

[0002] In the postoperative care and rehabilitation of anorectal diseases (such as hemorrhoids, anal fistula, perianal abscess, etc.), the cleaning and irrigation of the anorectal cavity is a key nursing step. Precise and gentle cavity irrigation can effectively remove wound secretions, residual feces and necrotic tissue, reduce bacterial growth, lower the risk of infection, relieve perianal sphincter spasm, reduce patient pain, and promote wound healing.

[0003] Patent document CN222623438U discloses a cavity irrigator for anorectal care, including a water tank structure. A cleaning groove structure is fixedly installed on the surface of the water tank structure, and an irrigation head structure is fixedly installed on the surface of the cleaning groove structure. A heating controller is fixedly installed on the surface of the water tank structure. This anorectal care cavity irrigator stores a certain amount of water through the water tank structure and heating controller, and then heats and controls the temperature to a suitable level before use. The cleaning groove structure facilitates wound cleaning, and warm air can be blown onto the wound after cleaning to quickly dry the medication. A small warm air blower is connected to a control panel for unified control. The irrigation head structure draws water or medication from the water tank structure and sprays it for rinsing. The spray head's control switch and water flow are adjusted via a ring to prevent excessive water flow from damaging the wound.

[0004] Current proctology irrigation equipment used in clinical practice has many shortcomings and is difficult to meet the needs of refined nursing care: Low irrigation precision and poor adaptability: The irrigation nozzles of traditional irrigation equipment are in fixed positions and cannot be flexibly adjusted according to the patient's anorectal cavity structure, lesion location and postoperative wound morphology. This can easily lead to irrigation blind spots or cause wound irritation and increased pain due to improper nozzle position. Although some equipment can be manually adjusted, the operation is cumbersome and it is difficult to ensure irrigation stability.

[0005] Inaccurate drug ratio and unstable heating temperature control: Anorectal care requires the use of specific concentrations of medication for flushing according to the patient's condition. Traditional equipment often uses manual dilution of medication, and the accuracy of the ratio depends on the experience of medical staff, which can easily lead to concentration deviations that affect the nursing effect. The medication is often heated by an external heating pot, which results in uneven heating temperature and cannot be monitored and adjusted in real time. Medication that is too cold can easily cause discomfort to patients, while medication that is too hot may damage the perianal mucosa.

[0006] Incomplete cleaning after rinsing and improper wastewater treatment: The wastewater after rinsing is mixed with secretions, necrotic tissue and other impurities. Traditional equipment lacks efficient cleaning and filtration mechanisms, and the wastewater is easy to remain in the cavities of the nursing bed, breeding bacteria and causing secondary pollution; direct discharge of impurities can easily lead to pipe blockage, which does not meet the medical wastewater treatment standards. In view of the shortcomings of the existing technologies, there is an urgent need to develop a cavity irrigator for anorectal care that has functions such as precise flushing, automated drug solution mixing and heating, efficient sewage cleaning and filtration, and multi-stage coordinated linkage, so as to improve the quality and efficiency of nursing care and ensure patient safety and comfort.

[0022] The implementation principle of a cavity irrigation device for anorectal care in this application embodiment is as follows: 1. Drug preparation and precise mixing stage: Medical staff set the drug concentration, dosage, and heating temperature parameters through the central control system 2 according to the patient's condition; the central control system 2 starts the second rotating motor 68, which drives the second screw 61 and the fourth rotating shaft 43 to rotate synchronously through two fourth synchronous toothed pulleys 70 and the fourth synchronous toothed belt 69; the fourth rotating shaft 43 drives multiple mixing blades 46 to rotate in the mixing chamber 37 through the meshing transmission of rotating gears 45; at the same time, the rotation of the second screw 61 drives the extrusion plate 59 to move backward along the metering tube 57. An internal negative pressure is generated, and the liquid medicine in the medicine storage chamber 50 is drawn into the metering tube 57 through the water pipe 55 and the second inlet check valve 56. Subsequently, the extrusion plate 59 moves forward, squeezing the metered liquid medicine into the mixing chamber 37 through the outlet check valve 58. At the same time, the water inlet check valve 47 opens, and clean water enters the mixing chamber 37 after being filtered by the filter 38. The mixing blade 46 rotates continuously to fully mix the liquid medicine and clean water. The liquid medicine concentration detection module 36 detects the concentration of the mixed liquid medicine in real time. If the concentration deviates, the central control system 2 automatically adjusts the input amount of liquid medicine or clean water until the concentration meets the set value. 2. Constant Temperature Heating Stage of the Liquid Medicine: During the mixing process, the rotating gear 45 of the mixing device drives the fifth bevel gear 49 to rotate. The fifth bevel gear 49 meshes with the fourth bevel gear 48, which drives the third synchronous toothed pulley 39 to rotate through the third rotating shaft 42. The third synchronous toothed pulley 39 drives another third synchronous toothed pulley 39 to rotate through the third synchronous toothed belt 40. The rotation of the other third synchronous toothed pulley 39 drives the gear transmission 54 to operate. The gear transmission 54 drives the fan blade 53 to rotate and generate airflow. At the same time, the central control system 2 starts the heating module 52. The airflow carries the heated heat into the heating chamber 33 through the intake one-way valve 51 to uniformly heat the liquid medicine in the mixing chamber 37. The temperature detection module 34 monitors the temperature of the liquid medicine in real time and feeds the data back to the central control system 2. When the temperature and concentration reach the set values, the central control system 2 adjusts the power of the heating module 52 and the speed of the fan blade 53 to maintain the constant temperature of the liquid medicine. 3. Precise Irrigation Stage: The patient lies supine on the surgical nursing bed 1, with the anorectal area aligned with the irrigation chamber 66. Medical staff activate the moving device and irrigation device via the central control system 2. The first rotating motor 6 starts, driving the first screw 17 and the second rotating shaft 9 to rotate via two first synchronous toothed pulleys 8 and the first synchronous toothed belt 7. The first screw 17 drives the first connecting rod 19 to move the irrigation device back and forth, adjusting the lateral position of the irrigation nozzle 5. Simultaneously, the cylinder 22 drives the sliding frame 14 to slide up and down along the sliding cylinder 16, adjusting the depth of the irrigation nozzle 5 into the anorectal cavity until it is aligned with the lesion. After the position is adjusted, the flow control pump 35 starts, delivering the constant-temperature medicine solution in the mixing chamber 37 to the irrigation nozzle 5 through the first inlet check valve 21, providing multi-angle gentle irrigation of the affected area through multiple arc-shaped irrigation holes. During the irrigation process, the flow control pump 35 precisely adjusts the irrigation flow according to nursing needs to avoid irritating the wound. At the same time, the second rotating shaft 9 drives the third... The bevel gear 27 rotates, and the third bevel gear 27 meshes with the second bevel gear 26 to drive the scraper 24 to rotate along the inner wall of the flushing chamber 66, scraping away residual sewage and impurities. The sewage pump 3 quickly extracts the sewage from the flushing chamber 66 and transports it to the sewage recovery tank 10. The second bevel gear 26 drives the first bevel gear 25 to rotate, the first bevel gear 25 drives the first rotating shaft 4 to rotate, the first rotating shaft 4 drives the second synchronous toothed pulley 11 to rotate, the second synchronous toothed pulley 11 drives another second synchronous toothed pulley 11 to rotate through the second synchronous toothed belt 12, the other second synchronous toothed pulley 11 drives the cam 32 to rotate, the cam 32 pushes the filter plate 30 to move up and down reciprocally, and with the help of the return spring 29, vibration filtration is achieved. Impurities in the sewage are intercepted on the filter plate 30, and the filtered sewage is discharged through the outlet one-way valve 13 for subsequent treatment. The filtered impurities fall into the pull-out ash collection box 64 through the discharge one-way valve 63 under the action of gravity, completing the sealed collection of impurities.

[0023] Example 2 The difference between this embodiment and Embodiment 1 is that a disposable dust cover is provided on the rinsing nozzle 5 to protect the nozzle.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
