Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0035] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0036] The terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0037] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0038] Referring to Figures 1-3 As shown, an intestinal stoma care device according to an embodiment of the present application includes:

[0039] A stoma bag body 1, the stoma bag body 1 is provided with a connection disk 2 for connecting to the patient's intestinal stoma, the connection disk 2 is in communication with the inside of the stoma bag body 1, a discharge port 3 is provided at the bottom of the stoma bag body 1, and a fixing strap 4 is provided on one side of the stoma bag body 1 close to the connection disk 2;

[0040] An air outlet assembly, the air outlet assembly is arranged on one side of the stoma bag body 1, and the air outlet assembly is in communication with the inside of the stoma bag body 1;

[0041] A liquid inlet assembly, the liquid inlet assembly is arranged at the top of the stoma bag body 1, and the liquid inlet assembly is in communication with the inside of the stoma bag body 1.

[0042] It should be understood that the ostomy bag body 1 is closely connected to the patient's intestinal stoma through the connection plate 2. The design of the connection plate 2 ensures a sealed connection between the ostomy bag and the intestinal stoma, preventing the leakage of excrement. The bottom of the ostomy bag body 1 is provided with an excretion port 3 for the convenient collection and treatment of excrement. When necessary, the patient or caregiver can empty the excrement in the ostomy bag by opening the excretion port 3. On one side close to the connection plate 2, the ostomy bag body 1 is provided with a fixing strap 4. This strap is used to firmly fix the ostomy bag to the patient's waist, ensuring that the ostomy bag does not shift or fall off during use and providing stable support. The air outlet assembly is arranged on one side of the ostomy bag body 1 and is internally connected. When the gas pressure inside the ostomy bag body exceeds a certain threshold, the air outlet assembly will automatically open to release the excess gas to maintain the pressure balance inside the ostomy bag. The liquid inlet assembly is located at the top of the ostomy bag body 1 and is internally connected. When it is necessary to clean the inside of the ostomy bag, the patient or caregiver can inject cleaning liquid into the ostomy bag through the liquid inlet assembly. The cleaning liquid will be evenly distributed through the atomizing nozzle to thoroughly clean the inside of the ostomy bag.

[0043] Specifically, through effective connection and sealing designs, as well as the fixing strap, the stability and safety of the ostomy bag during use are ensured, reducing the discomfort and psychological pressure of the patient, thereby improving the patient's quality of life. The design of the liquid inlet assembly and the atomizing nozzle makes the cleaning of the inside of the ostomy bag simple and convenient. This not only helps to keep the ostomy bag clean and hygienic but also reduces the possibility of bacterial growth and the risk of infection.

[0044] In some specific embodiments, a downwardly inclined diversion tube 5 is provided on the inner wall of the ostomy bag body 1 on the side close to the connection plate 2, and the diversion tube 5 is communicated with the connection plate 2.

[0045] It should be understood that the design of the downwardly inclined diversion tube 5 effectively prevents the splashing of excrement in all directions and avoids the pollution of the surrounding environment. At the same time, the automatic release function of the air outlet assembly also helps to reduce the odor and discomfort that may be caused by gas accumulation.

[0046] In some specific embodiments, a sealing block 6 is provided at the top inside the ostomy bag body 1, and the outer diameter of the sealing block 6 matches the inner diameter of the ostomy bag body 1.

[0047] In some specific embodiments, the excretion port 3 coincides with the axis line of the ostomy bag body 1, and an excretion cover 7 is threadedly connected to the excretion port 3.

[0048] In some specific embodiments, two fixing straps 4 are symmetrically arranged with the axis line of the ostomy bag body 1 as the axis of symmetry.

[0049] In some specific embodiments, the air outlet assembly includes:

[0050] An air outlet head 8, the air outlet head 8 is arranged on the side wall of the ostomy bag body 1, and an air inlet cover 9 is threadedly sealed to the air outlet head 8;

[0051] An air outlet pipe 10, one end of the air outlet pipe 10 is communicated with the air outlet head 8, and the other end of the air outlet pipe 10 penetrates through the ostomy bag body 1 and the sealing block 6 to be communicated with the inside of the ostomy bag body 1;

[0052] A ventilation assembly, the ventilation assembly is arranged inside the air outlet pipe 10, and the ventilation assembly is located on the side of the air outlet pipe 10 close to the air outlet head 8.

[0053] In some specific embodiments, the ventilation assembly includes:

[0054] Support plates 11, two support plates 11 are symmetrically arranged with respect to the transverse axis line of the air outlet pipe 10, and both support plates 11 are fixedly connected to the inner wall of the air outlet pipe 10, and a first circular through hole 12 is formed between the two support plates 11;

[0055] A support frame 13, the support frame 13 is located on the side of the support plate 11 close to the air outlet head 8, the bottom of the support frame 13 is fixedly connected to the side walls of the two support plates 11 respectively, a spring 14 is fixedly connected to the side of the support frame 13 close to the support plate 11, the spring 14 is perpendicular to the support plate 11, and the axis of the spring 14 coincides with the axis of the support frame 13;

[0056] A sealing body 15, the axial cross section of the sealing body 15 is a triangular structure, one end of the sealing body 15 is fixedly connected to the spring 14, and the other end of the sealing body 15 is sealingly connected to the first circular through hole 12.

[0057] It should be understood that when the air pressure inside the ostomy bag body 1 is greater than the bearing pressure of the spring 14, the gas pushes the sealing body 15 away from the first circular through hole 12, and at this time, the gas inside the ostomy bag body 1 flows out through the first circular through hole 12.

[0058] When the air pressure inside the ostomy bag body 1 is normal, the ventilation component is in a closed state. At this time, the sealing body 15 is closely attached to the first circular through-hole 12 under the elastic force of the spring 14 to form a seal, preventing the gas inside the ostomy bag from leaking. When the air pressure inside the ostomy bag body 1 increases due to excrement production or external factors (such as patient movement, environmental changes), the gas begins to exert pressure on the sealing body 15. As the air pressure continues to rise, the pressure of the gas on the sealing body 15 gradually overcomes the elastic force of the spring 14. When the air pressure exceeds the bearing pressure of the spring 14, the sealing body 15 is pushed by the gas to disengage from the first circular through-hole 12. Once the sealing body 15 is pushed open, the gas inside the ostomy bag body 1 quickly flows out through the first circular through-hole 12 until the internal air pressure drops to a safe range. After the air pressure inside the ostomy bag body 1 decreases, the elastic force of the spring 14 causes the sealing body 15 to reattach to the first circular through-hole 12, restoring the sealed state and preparing to respond to the next possible increase in air pressure.

[0059] In some specific embodiments, a gas filter plate 16 is further provided inside the air outlet pipe 10, and the gas filter plate 16 is located on the side of the air outlet pipe 10 away from the support plate 11.

[0060] In some specific embodiments, the liquid inlet assembly includes:

[0061] A liquid inlet head 17, and a liquid inlet cover 18 is threadedly sealed to the liquid inlet head 17;

[0062] A first liquid inlet pipe 19, which is communicated with the liquid inlet head 17. The first liquid inlet pipe 19 is located on the side of the ostomy bag body 1 close to the connection disk 2, and the first liquid inlet pipe 19 penetrates through the ostomy bag body 1 and the sealing block 6 to be communicated with the inside of the ostomy bag body 1;

[0063] A second liquid inlet pipe 20, one end of the second liquid inlet pipe 20 is communicated with the first liquid inlet pipe 19, and the other end of the second liquid inlet pipe 20 penetrates through the sealing block 6 to be communicated with the inside of the ostomy bag body 1;

[0064] Atomizing nozzles 21 are communicated with one ends of the first liquid inlet pipe 19 and the second liquid inlet pipe 20 close to the discharge port 3.

[0065] In some specific embodiments, a liquid inlet 22 is provided at the top of the atomizing nozzle 21. The atomizing nozzle 21 is communicated with the first liquid inlet pipe 19 or the second liquid inlet pipe 20 through the liquid inlet 22. A flow cavity 23 communicated with the liquid inlet 22 is arranged inside the atomizing nozzle 21. An impact block 24 is arranged inside the flow cavity 23 corresponding to the liquid inlet 22. A plurality of spray ports 25 are arranged at the bottom of the atomizing nozzle 21 in an annular array with the axis line of the atomizing nozzle 21 as the axis. All the plurality of spray ports 25 are communicated with the flow cavity 23.

[0066] It should be understood that the liquid inlet head 17 is hermetically connected to the liquid inlet cover 18 by threads to ensure that the inside of the ostomy bag body 1 remains sealed when no cleaning operation is performed. The first liquid inlet pipe 19 and the second liquid inlet pipe 20 are respectively communicated with the liquid inlet head 17, penetrate through the ostomy bag body 1 and the sealing block 6, and are communicated with the inside of the ostomy bag body 1. In this way, the cleaning liquid can enter the ostomy bag body 1 through these two liquid inlet pipes. When the cleaning liquid flows into the atomizing nozzle 21 through the first liquid inlet pipe 19 or the second liquid inlet pipe 20, it first enters the flow cavity 23 through the liquid inlet 22. Inside the flow cavity 23, the cleaning liquid impacts on the impact block 24, forming a turbulent flow and a pressure change, so that the liquid is dispersed into tiny droplets. These tiny droplets are ejected through a plurality of spray ports 25 communicated with the flow cavity 23 to form an atomizing effect. The atomized cleaning liquid can be more evenly distributed on the inner wall of the ostomy bag body 1, improving the cleaning effect. The design of the atomizing nozzle 21 enables the cleaning liquid to cover a large area of the ostomy bag body 1 in a mist form, including hard-to-reach corners and crevices, so as to achieve a comprehensive and thorough cleaning.

[0067] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
