Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical devices, and particularly relates to an auxiliary device for jejunostomy nursing. BACKGROUND

[0002] Jejunostomy is a common surgical procedure, mainly used for the treatment of various digestive tract diseases; however, the stool of jejunostomy is usually thin, large in amount and frequent in times, and such characteristics make the excrement easy to accumulate around the stoma. More importantly, the excrement of jejunostomy contains undigested food residues and digestive enzymes, which have strong irritability to the skin and can easily cause skin problems such as dermatitis, bringing additional pain to the patient.

[0003] In addition, most patients with jejunostomy are loop fistulas. Under the background of the increasing number of obese people year by year, it is more difficult to lift the intestinal loop to the surface of the abdominal skin. This results in many patients' jejunostomy being low, concave, or even tilting to the skin side. Such stoma morphology makes it easier for excrement to accumulate in the concave part, which not only hinders the discharge of excrement, but also affects the healing of the wound and increases the risk of infection.

[0004] Therefore, there is an urgent need for an auxiliary device that can adapt to the nursing needs of jejunostomy. The device can firmly fix on the stoma and prevent it from falling off, lift the opening of the intestinal stoma, smoothly divert the intestinal contents, and facilitate the nursing operation of the stoma. In addition, by optimizing the shape of the stoma, the device can better adhere to the stoma bag, reduce the possibility of excrement leakage, and effectively protect the patient's skin, reducing the risk of complications such as intestinal fistula and anastomotic fistula. SUMMARY

[0005] In order to solve the above technical problems, the present application designs an auxiliary device for jejunostomy nursing. The device can be embedded in the patient's stoma to connect the intestinal tract to the outside, and by inflating or adding liquid, the device can be inflated to firmly fix the device and open the intestinal cavity. The device can lift the opening of the intestinal stoma, divert the intestinal contents, and facilitate the nursing operation of the stoma. It can also better adhere to the stoma bag, protect the patient's skin, and reduce the risk of intestinal fistula and anastomotic fistula.

[0006] In order to achieve the above technical effects, the present application discloses an auxiliary device for jejunostomy nursing, comprising: an embedded air bag, a transition section, and an outer fixing disc; one end of the transition section is fixedly connected to the embedded air bag, and the other end of the transition section is fixedly connected to the outer fixing disc; the embedded air bag is a hollow inflatable air bag structure; Further, the embedded air bag comprises: a diversion section and a fixed section; the diversion section is a hollow boss structure with a narrow-to-wide structure; the fixed section is fixedly connected to the wide part of the diversion section; the fixed section is a hollow circular ring structure; Furthermore, the narrow section of the embedded airbag is provided with a smooth entrance; Furthermore, an injection valve is provided on the inner side of the embedded airbag; air or saline can be injected into the embedded airbag through the injection valve to expand the embedded airbag, thereby fixing the device and preventing it from falling out of the stoma, while expanding the intestinal cavity to facilitate the discharge of feces. Furthermore, the embedded airbag is made of medical silicone rubber material with corrosion resistance, good biocompatibility and high elasticity; Furthermore, the outer diameter of the transition section is smaller than the outer diameter of the widest portion of the embedded airbag, and the outer diameter of the transition section is smaller than the outer diameter of the outer fixing plate; Furthermore, a curling edge with an inwardly concave structure is provided on the outer side of the outer fixing plate; the curling edge can lift the stoma position outward to prevent the stoma driving device from sinking inward; Furthermore, the transition section and the outer fixing plate are made of polycarbonate with high strength and good toughness.

[0007] The beneficial effects of the present invention are: The present invention discloses an auxiliary device for jejunostomy care. First, the device, through the expansion and fixation function of the embedded airbag, can be firmly embedded in the patient's stoma, effectively preventing the device from falling out during daily activities, thereby providing stable support for the stoma. Furthermore, the device's diversion section design can elevate the stoma opening, optimize the discharge path of intestinal contents, reduce the accumulation of intestinal contents around the stoma, and reduce skin irritation and corrosion, thereby protecting the skin around the stoma.

[0008] In addition, the concave curling structure of the outer fixing disk of the device can effectively prevent the stoma from driving the device inward, enhance the stability of the device, and at the same time avoid the risk of intestinal content reflux and infection caused by the inward collapse of the device.

[0009] The embedded balloon is made of medical silicone rubber, which is corrosion-resistant, biocompatible, and highly elastic. This not only ensures safe contact between the device and human tissue, but also adapts to intestinal physiological movements, minimizing patient discomfort. The transition section and outer fixing disc are constructed from high-strength, high-toughness polycarbonate, ensuring the overall structural strength and durability of the device. The transparency of polycarbonate also facilitates observation of the skin condition at the stoma, facilitating timely detection of abnormalities. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0013] Example 1 The present invention discloses an auxiliary device for jejunostomy care, Figures 1 to 8 The intestinal tract is composed of an embedded airbag 1, a transition section 2, and an outer fixing plate 3. One end of the transition section 2 is fixedly connected to the embedded airbag 1, and the other end is fixedly connected to the outer fixing plate 3. The embedded airbag 1 is hollow and can be expanded by inflation or injection of liquid, thereby achieving the function of fixing and expanding the intestinal cavity.

[0014] The embedded airbag 1 is specifically divided into two parts: a diverter section 101 and a fixed section 102. The diverter section 101 is a hollow boss structure that extends from narrow to wide. This structure can better adapt to the shape of the stoma and facilitate the installation of the device inside the stoma. The fixed section 102 is a hollow annular structure that is fixedly connected to the wide part of the diverter section 101 to firmly fix the device to the stoma. In addition, the narrow section of the embedded airbag 1 is specially designed with a smooth entrance to facilitate the smooth insertion of the device into the stoma, reduce irritation to the stoma, and reduce pain for the patient.

[0015] To expand the embedded airbag 1, an injection valve 4 is located on its inner side. This valve allows air or saline to be injected into the embedded airbag 1. Once inflated, the embedded airbag 1 securely secures to the stoma, preventing it from falling out. It also expands the intestinal cavity, providing a smoother passage for fecal discharge. The outer side of the outer fixing plate 3 features a concave hem. This hem raises the stoma outward, effectively preventing the stoma from causing the device to collapse inward.

[0016] Example 2 The embedded balloon 1 is constructed from medical silicone rubber. This material offers corrosion resistance, excellent biocompatibility, and high elasticity, ensuring safety and comfort when in contact with human tissue. Furthermore, the high elasticity of medical silicone rubber enables the embedded balloon 1 to maintain stable performance in various inflation states, adapting to the physiological movements of the intestine.

[0017] Finally, the transition section 2 and the outer fixing plate 3 are both made of polycarbonate. Polycarbonate has high strength and good toughness, which can provide sufficient structural strength for the device, ensuring its durability and reliability in daily use. At the same time, polycarbonate has good transparency, which makes it easy for medical staff to observe the internal situation of the device and detect abnormalities in time. The working principle and usage process of this device are as follows: First, the medical professional aligns the device's embedded balloon (1) with the patient's jejunostomy and slowly inserts it. Thanks to the smooth, rounded entrance design of the narrow section of the embedded balloon (1), this process is relatively smooth and minimizes irritation to the patient's intestinal mucosa. At this point, the embedded balloon (1) has not yet expanded; its soft medical silicone rubber material allows it to conform to the shape of the stoma, initially achieving device positioning.

[0018] The medical professional then injects air or saline into the balloon through the injection valve 4 connected to the inside of the embedded balloon 1. As the gas or liquid is injected, the embedded balloon 1 begins to expand. The expanded balloon securely secures the stoma, preventing the device from falling out during the patient's daily activities. Furthermore, its increased volume expands the intestinal cavity, providing a smoother passage for intestinal contents, reducing the accumulation of intestinal contents around the stoma, and minimizing the risk of skin irritation and corrosion.

[0019] In the structural design of the device, the embedded airbag 1 is divided into a diverting section 101 and a fixed section 102. The hollow boss structure of the diverting section 101, which is narrow to wide, can better guide the flow direction of intestinal contents and allow them to be discharged smoothly from the body.

[0020] The concave curling structure of the outer fixing plate 3 can lift the stoma position outward, effectively preventing the stoma from driving the device inward, avoiding the risk of intestinal content reflux and infection caused by the device inward, and also helps to stick the ostomy bag, ensuring its close fit with the skin, and further protecting the skin around the stoma.

[0021] The entire device's transition section 2 and outer fixing plate 3 are made of high-strength, high-toughness polycarbonate. This material not only provides the device with sufficient structural strength, ensuring its durability and reliability in daily use, but also complements the medical silicone rubber embedded in the airbag 1, achieving a balance between the device's overall mechanical properties and biocompatibility.

[0022] In terms of usage, after the medical staff has inserted and inflated the device, they can attach the ostomy bag to the device's outer fixing plate 3. Because the device elevates the stoma and optimizes the discharge path for intestinal contents, the bag can more stably collect intestinal contents and reduce the possibility of leakage. During the nursing process, the medical staff can adjust the inflation level of the embedded airbag 1 as needed using the injection valve 4 to ensure that the device is always in optimal working condition. When it is necessary to replace the ostomy bag or perform other nursing procedures, the embedded airbag 1 can be easily removed by simply returning it to its original state by venting or draining liquid.

[0023] 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 details in detail, nor do they limit the invention to only the specific implementation methods described.
