Description

Technical Field

[0001] The invention relates to the field of anorectal surgical technical equipment, in particular to an anorectal post-operative wound cleaning device. Background Art

[0002] Anorectal postoperative cleaning device is an auxiliary care device specially designed for anorectal surgery patients. It is mainly used for cleaning postoperative wounds to prevent infection and promote wound healing. After anorectal surgery, the patient's perianal area is usually in a highly sensitive state and is susceptible to bacterial infection, especially after operations such as hemorrhoid surgery, anal fissure repair or anal fistula surgery. Therefore, it is very important to keep the postoperative area clean. With the development of medical technology, in order to reduce the inconvenience and pain of patients during postoperative care, various anorectal postoperative cleaning devices have gradually been introduced on the market. This type of equipment can provide patients with a gentle cleaning method that meets physiological needs, greatly improving the comfort and convenience of postoperative care. Existing anorectal postoperative wound cleaning devices can basically meet most of the needs, but there are still the following technical problems: Due to the hidden location and special structure of the anus and perianal wounds, the many perianal skin folds and the closed nature of the anus make it difficult to expose the wound after anorectal surgery. Traditional cleaning methods cannot completely clean the exudate, secretions and feces in the wound surface, which will cause wound pain, redness and swelling, and even delay wound healing.

A triangular support plate 13 is fixedly installed at the connection between the push rod 201 and the telescopic rod 102, thereby enhancing the bearing capacity of the device. The other end of the push rod 201 is slidably installed inside the base 202, and a cylindrical protrusion is provided on the surface of the push rod 201. A plurality of slide grooves for limiting the sliding direction of the push rod 201 are provided on the base 202 along the radial direction. The disc 203 is provided through the push rod 201. The handle 204 is fixed on the disc 203, and the disc 203 is provided with an arc-shaped slide groove, and the cylindrical protrusion on the push rod 201 passes through the base 202; the handle 204 is fixed on the disc 203, and the disc 203 is driven to rotate by turning the handle 204, and the arc-shaped slide groove on the disc 203 pushes the cylindrical protrusion on the push rod 201 to move along the slide groove, thereby driving the push rod 201 to perform inward and outward expansion movement in the slide groove of the base 202, and the cover plate 205 is fixedly installed on the base 202; the motor 3 is fixedly installed on the cover plate 205, and the turntable 4 is fixedly connected to the transmission shaft of the motor 3 The water tank 5 is annular and fixedly installed on the outer ring of the turntable 4. The inner wall of the water tank 5 is a heat-conducting material and a temperature-controlled heater is fixedly installed on the inner wall. The lower end of the water pipe 9 is fixedly installed on the turntable 4. A suction and pressure pump 8 is fixedly installed on the turntable 4. One end of the suction and pressure pump 8 is connected to the water pipe 9, and the other end is connected to the water tank 5. A multifunctional nozzle 10 is installed on the upper end of the water pipe 9. The bottom of the multifunctional nozzle 10 is spherical and connected to the water pipe 9 through a structure similar to a spherical joint. A wastewater bag 12 is installed below the movable plate 101, and a water outlet 11 is provided below the wastewater bag 12; Since the wounds of the anus and perianal area are relatively hidden, and the structure of this area is special, there are many wrinkles in the perianal skin, and the anus itself has a strong closure, it is difficult to fully expose the wound after anorectal surgery, which brings certain difficulties to postoperative care and cleaning. Based on this problem, the present invention specially designs an expansion mechanism 2, which can work in coordination with other structures to solve the problem of the wound being difficult to expose by appropriately expanding the skin of the patient's buttocks. The specific implementation method is: the patient sits on a movable board 101 with adjustable height, and the movable board 101 adjusts the patient's sitting height through a telescopic rod 102 to adapt to patients with different body shapes or care needs; then, through By rotating the handle 204, the disc 203 is driven to rotate, so that the push rod 201 moves outward, and the push rod 201 further pushes the movable plate 101 to expand outward; in this process, a certain friction force is generated between the movable plate 101 and the patient's skin, and the protrusion design on the movable plate 101 can provide appropriate thrust for the buttocks skin to expand outward; in this way, the patient's buttocks skin can be properly expanded outward, and the skin folds can also be unfolded; through this design, the exposed area of ​​the postoperative wound can be significantly increased, which is convenient for doctors or nursing staff to perform cleaning or nursing operations, reduces obstacles during cleaning, and helps to better keep the postoperative wound clean; The flushing process of the present invention is as follows: when the patient sits on the device, first adjust the height of the sitting posture, and appropriately expand the patient's buttocks through the expansion mechanism 2 to fully expose the anus and perianal wound area, in preparation for the subsequent cleaning operation; then, the device enters the flushing mode; during flushing, the device pumps out the water in the water tank 5 through the suction pump 8, and transports it to the multi-functional nozzle 10 through a pipeline; the water in the water tank 5 is heated by the temperature control heating plate 7 before use to ensure that the water temperature is always maintained within a comfortable and safe range to avoid any adverse stimulation or damage to the postoperative wound; the water tank 5 is designed as an annular structure, which can increase the contact area between the water tank 5 and the temperature control heating plate 7, thereby significantly improving the heating efficiency and allowing the water to quickly reach the required temperature; the working pressure of the suction pump 8 can be adjusted according to the specific situation to ensure that the water flow intensity during flushing will neither cause impact on the wound nor achieve a cleaning effect; the multi-functional nozzle 10 adopts the existing technology, and the nozzle 10 can be changed by rotating the nozzle 10 The spraying mode can be changed, and the patient can choose mist spray or water column spray according to the needs; the mist nozzle 10 is suitable for relatively gentle flushing, while the water column nozzle 10 is suitable for deeper cleaning; in addition, the multifunctional nozzle 10 is connected to the water pipe 9 through a mechanism similar to a spherical joint, so that the nozzle 10 can freely adjust the direction to ensure that the water flow can accurately cover the perianal area; a certain angle is designed between the water pipe 9 and the turntable 4, so that during the flushing process, the rotation of the turntable 4 can drive the water pipe 9 and the nozzle 10 to automatically rotate around the wound for all-round cleaning; this function can effectively and automatically flush various positions around the anus to ensure that the cleaning process is more thorough and comprehensive; through the mutual cooperation of the above-mentioned functions, the entire flushing process can be automated, avoiding the trouble of manual cleaning, and at the same time can flexibly adapt to the different conditions of various patients to ensure that the cleaning effect has no dead angles; this design not only improves the cleaning efficiency, but also ensures the comfort and safety of the patient, making postoperative care more perfect; The preferred embodiments of the present invention disclosed above are only used to help illustrate the present invention. The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
