TECHNICAL FIELD
[0001] The present application relates to the technical field of medical equipment, in particular to a special integrated assembly for perioperative treatment of small intestinal air fistula. BACKGROUND
[0002] Small intestinal air fistula is a special type of intestinal fistula, which is characterized by the entry of intestinal contents into the abdominal cavity or outside the body through the fistula, often accompanied by complications such as infection, malnutrition, and water and electrolyte imbalance. Perioperative treatment requires comprehensive consideration of drainage, infection control, nutritional support, and fistula repair. A special integrated assembly integrates multiple treatment functions through modular design to achieve precise and individualized treatment.
[0003] The conventional small intestinal air fistula treatment device currently available typically includes a protective cover, a wound plugging assembly, an enteral nutrition input channel, and a negative pressure flushing assembly to achieve the functions of isolating the wound, plugging the fistula, flushing and draining the leaked intestinal fluid, and enteral nutrition infusion at the intestinal fistula site.
[0004] In the prior art, the protective cover of the treatment device is usually attached to the small intestinal air fistula tissue by negative pressure, and then is stably fixed on the human body under the extrusion of the wound plugging assembly. Although this method can prevent the protective cover from falling off, a large negative pressure is required between the protective cover and the human body, and the intestinal tissue near the fistula is prone to deformation and protrusion into the protective cover. However, the intestinal tissue does not have the contractility and elasticity similar to muscle, and such deformation can reduce the plugging effect of the wound plugging assembly or even tear the fistula.
[0005] Therefore, there is a need to design a special integrated assembly for perioperative treatment of small intestinal air fistula. SUMMARY
[0006] In order to overcome the shortcomings of the existing air fistula treatment device, which is usually fixed by negative pressure and the intestinal tissue is prone to deformation and protrusion into the protective cover, resulting in reduced plugging effect of the wound plugging assembly or even tearing of the fistula, the technical problem of the present application is to provide a special integrated assembly for perioperative treatment of small intestinal air fistula.

[0013] To further explain, the first connecting tube is inserted into the pipe that connects the negative pressure suction tube to the external negative pressure suction device.
[0014] The present invention has the following beneficial effects: 1. The present invention, by adhering closely to the patient's skin through the outer periphery of the protective cover or even multiple negative pressure chambers, helps to better fix the protective cover to the patient's body.

[0035] The lower part of the support pipe 3 is provided with a pad pressure mechanism 11 for shaping the intestinal components around the stoma.
[0036] For example, in use, the medical staff first individually tailor the occlusion sheet 4 according to the size of the stoma and the running of the intestinal tube of the stoma according to different conditions of the patient, insert it into the stoma, and lightly lift it outward to occlude the stoma, while the protective cover 1 surrounds and covers the stoma, then lightly press the elliptical cover 2 towards the stoma to form a suitable pressure and tightness, so that it is not easy to loosen, in this way, the flushing and drainage of the leaked intestinal fluid is operated through the flushing pipe 6 and the negative pressure liquid suction pipe 5, the granulation tissue around the stoma is kept moist and relatively clean, the healing of the tissue around the small intestinal air stoma is promoted, the external environment and the small intestine are connected through the support pipe 3, the intestinal continuity is timely restored, the enteral nutrition is provided to the patient in the first time, and the conditions for the certain operation are provided, and after the placement of the protective cover 1 is completed, the negative pressure chambers 8 are tightly attached to the patient's skin by pressing the extension ring 7, then the external air pump is started to draw air in the negative pressure chambers 8 through the first connecting pipe 10, so that a negative pressure is formed in the negative pressure chambers 8, and finally the multiple negative pressure chambers 8 also produce an adsorption effect on the patient's skin, which assists the fixation of the protective cover 1 on the patient's body, in this way, even if the negative pressure between the protective cover 1 and the small intestinal air stoma is small, the protective cover 1 can also be prevented from falling off the patient's body, and the purpose of stably fixing the protective cover 1 on the human body and preventing the intestinal tissue near the stoma from deforming and protruding into the protective cover 1 is achieved.

[0040] The outer side of the upper part of the communication frame 1102 is uniformly and regularly provided with a plurality of branch pipes 1104, the branch pipes 1104 are communicated with the communication frame 1102, and the ends of the branch pipes 1104 away from the communication frame 1102 are connected with a wave-shaped annular extrusion pipe 1105, the wave-shaped extrusion pipe 1105 and the mesh-shaped protruding lines of the plugging air cushion 1101 correspond to each other in shape after being inflated, which is used for shaping and positioning the small intestinal tissue around the fistula together with the plugging air cushion 1101.
[0041] In the initial state, there is no air in the plugging air cushion 1101, the branch pipe 1104 and the extrusion pipe 1105, when the plugging piece 4 is inserted into the small intestine from the fistula, the plugging air cushion 1101 is also deformed and sent into the small intestine, the branch pipe 1104 is bent, and the extrusion pipe 1105 is isolated outside the small intestine, and after the plugging of the plugging piece 4 is completed, air is introduced into the communication frame 1102 through the second connecting pipe 1103, the plugging air cushion 1101 is inflated, the branch pipe 1104 and the extrusion pipe 1105 are also inflated, the small intestinal wall is clamped between the extrusion pipe 1105 and the plugging air cushion 1101, and the small intestinal fistula tissue is covered in the middle of the annular extrusion pipe 1105, so that the small intestinal fistula tissue is further prevented from deforming and protruding into the protection cover 1 by the extrusion and fixation of the extrusion pipe 1105 and the plugging air cushion 1101, and the wave-shaped extrusion pipe 1105 and the mesh-shaped protruding lines of the plugging air cushion 1101 can also assist the plugging piece 4 to plug the fistula.
[0042] Embodiment 2
[0043] As shown in Figure 6 and Figure 7 based on the embodiment 1, the specific further includes a separation mechanism 12, the separation mechanism 12 specifically includes a limiting ring 1201, a guide column 1202, a sealing plate 1203 and an embedded block 1204, the inner side of the lower part of the negative pressure chamber 8 is provided with the limiting ring 1201, the side wall around the inside of the negative pressure chamber 8 is provided with the guide column 1202, the inner side of the negative pressure chamber 8 is provided with the sealing plate 1203 in a sliding mode, the position close to the guide column 1202 of the sealing plate 1203 is provided with the embedded block 1204, and the embedded block 1204 is in sliding fit with the guide column 1202.
[0044] The sealing plate 1203 in the negative pressure chamber 8 is initially located on the top of the limiting ring 1201, and there is air in the space formed between the sealing plate 1203 and the inside of the negative pressure chamber 8. When the negative pressure chamber 8 is attached to the skin of the patient and the inside of the negative pressure chamber 8 is pumped through the first connecting pipe 10, the air pressure in the space between the sealing plate 1203 and the negative pressure chamber 8 decreases, the sealing plate 1203 slides upward, the space between the sealing plate 1203 and the bottom of the negative pressure chamber 8 increases, and the negative pressure chamber 8 is tightly attached to the skin of the patient. In this way, the sealing plate 1203 separates the first connecting pipe 10 from the human body in the negative pressure chamber 8, so even if the negative pressure chamber 8 leaks because it is not tightly attached to the patient, it will not affect other negative pressure chambers 8. In the above process, the guide column 1202 and the embedded block 1204 guide the movement of the sealing plate 1203.
[0045] As shown in Figure 8 and Figure 9 Further comprising a guide mechanism 13, the guide mechanism 13 specifically comprises a first elastic strip 1301, a fixed ring 1302, and a second elastic strip 1303. The first elastic strip 1301 is arranged on the upper side wall inside the branch pipe 1104. When the first elastic strip 1301 is straightened, it is concave to fit the branch pipe 1104, and when it is not straightened, it is coiled along the length direction. The fixed ring 1302 is arranged at both ends of the first elastic strip 1301 along the length direction. The second elastic strip 1303 is arranged in the middle of the first elastic strip 1301.
[0046] When the branch pipe 1104 is not inflated and straightened, the second elastic strip 1303 is straight along the length direction of the second elastic strip 1303, and the connection between the first elastic strip 1301 and the second elastic strip 1303 is also straightened. Since the first elastic strip 1301 is coiled along the length direction when it is not straightened, and the two ends of the first elastic strip 1301 are fixed by the fixed ring 1302, the first elastic strip 1301 will be bent and folded at the connection between the first elastic strip 1301 and the second elastic strip 1303 in this state. Under the action of the first elastic strip 1301, the extrusion pipe 1105 is lifted upward to avoid affecting the placement of the blocking sheet 4 and the blocking air cushion 1101. After the branch pipe 1104 is inflated, the branch pipe 1104 gradually straightens, the first elastic strip 1301 is straightened under the action of the branch pipe 1104 and forms a concave shape to fit the branch pipe 1104, and the second elastic strip 1303 is bent again along the length direction of the second elastic strip 1303. In the whole process, the bending and straightening of the branch pipe 1104 only occur within the up-down range under the action of the first elastic strip 1301, and will not deviate to the horizontal direction. This can avoid the deviation and dislocation of the extrusion pipe 1105 and the mesh protrusions of the blocking air cushion 1101. Moreover, after the branch pipe 1104 is straightened, the first elastic strip 1301 can also play a role as a skeleton to assist in supporting the branch pipe 1104.
[0047] As Figure 10 And Figure 11 Also include the limiting mechanism 14, the limiting mechanism 14 specifically includes the connecting ring 1401, rotating ring 1402 and counterweight 1403, the oval cover 2 and the protective cover 1 close to each other one end is provided with the connecting ring 1401, the connecting ring 1401 between the oval cover 2 and the protective cover 1 is rotatably provided with rotating ring 1402, the inner side of rotating ring 1402 is recessed and matched with the flushing pipe 6, the position of the outer side of rotating ring 1402 away from the flushing pipe 6 is provided with the counterweight 1403;The shape wire 1404, the flushing pipe 6 is provided with the shape wire 1404 inside.
[0048] When the stoma is flushed, medical staff or patients can manually control the rotating ring 1402 to rotate the flushing pipe 6 around the support pipe 3, so that it can better flush around the stoma, and when the patient sits up or rotates the body, the counterweight 1403 can drive the rotating ring 1402 to rotate, so that the counterweight 1403 is below the rotating ring 1402, and the flushing pipe 6 is kept above the stoma, avoiding the flushing pipe 6 from being unable to flush the stoma due to gravity. The shape wire 1404 in the flushing pipe 6 can fix the shape of the flushing pipe 6, avoiding the deformation of the flushing pipe 6 due to gravity.
[0049] As Figure 12 Also include the sealing sheet 15, the bottom of the protective cover 1 is provided with the annular sealing sheet 15 which expands outward from top to bottom, the vertical section of the sealing sheet 15 is arc-shaped, and the material of the sealing sheet 15 is medical soft silicone.
[0050] The annular sealing sheet 15 at the bottom of the protective cover 1 can deform and adhere to the human body when the negative pressure between the protective cover 1 and the human body is small, better forming a sealing structure, so that the protective cover 1 can better adsorb on the patient's body.
[0051] The first connecting pipe 10 penetrates into the pipeline connected with the external negative pressure aspirator in the negative pressure liquid suction pipe 5.
[0052] The first connecting pipe 10 penetrates into the pipeline connected with the external negative pressure aspirator in the negative pressure liquid suction pipe 5, and then penetrates out to be connected with the external air pump, so that the number of exposed pipelines can be reduced, and the entanglement between the pipelines can be avoided to affect the normal use of the device.
[0053] Although the present application has been described with reference to the example embodiments, it should be understood that the present application is not limited to the disclosed example embodiments. The scope of the following claims should be given the broadest interpretation so as to encompass all variations and equivalents.
