Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a special integrated component for perioperative treatment of small intestinal air fistula. Background Art

[0002] Small intestinal air fistula is a special type of intestinal fistula, in which intestinal contents enter the abdominal cavity or outside the body through the fistula, and are often accompanied by complications such as infection, malnutrition, and water and electrolyte imbalance. Surgical treatment requires comprehensive consideration of drainage, infection control, nutritional support, fistula repair and other aspects. Dedicated integrated components integrate multiple treatment functions into one through modular design to achieve precise and individualized treatment.

[0003] Currently, traditional intestinal air fistula treatment equipment usually includes several parts such as a protective cover, a wound sealing component, an enteral nutrition input channel and a negative pressure flushing component to achieve the functions of isolating the wound surface of the intestinal fistula, sealing the fistula, flushing and draining leaked intestinal fluid and infusing enteral nutrition.

[0004] In the prior art, the protective cover of the treatment device is usually adsorbed around the small intestinal air fistula tissue through negative pressure, and then the protective cover is stably fixed on the human body under the squeezing action of the wound sealing component. Although this method can prevent the protective cover from falling off, the negative pressure required between the protective cover and the human body is relatively large, and the intestinal tissue near the fistula is easily deformed and bulged into the protective cover. However, the intestinal tissue does not have the contractility and elasticity of muscles. Such deformation can easily lead to a reduction in the sealing effect of the wound sealing component or even tearing of the fistula.

[0005] Therefore, there is a need to design an integrated component specifically for the perioperative treatment of intestinal air fistula. Summary of the Invention

[0006] In order to overcome the shortcomings of existing air fistula treatment equipment, which is usually fixed by negative pressure adsorption, and intestinal tissue is easily deformed and protruded into the inside of the protective cover, resulting in reduced sealing effect of the wound sealing component and even fistula tearing, the technical problem of the present invention is to provide an integrated component specifically for the perioperative treatment of small intestinal air fistula.

DETAILED DESCRIPTION

[0029] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.

[0030] Example 1

[0031] like Figures 1 to 5 As shown, the present invention provides an integrated component specifically for perioperative treatment of small intestinal air fistula, specifically comprising a protective cover 1, a support tube 3; a blocking piece 4, a negative pressure liquid suction tube 5, an irrigation tube 6, an elliptical cover 2, an extension ring 7, a negative pressure chamber 8, a connecting tube 9, a first connecting tube 10 and a cushioning mechanism 11;

[0032] Among them, a support tube 3 is provided upwardly through the inside of the protective cover 1, and a sealing piece 4 made of silicone material is provided at the bottom of the support tube 3. The sealing piece 4 is located below the protective cover 1. An annular negative pressure liquid suction tube 5 is provided at the lower part of the inner wall of the protective cover 1. A plurality of liquid suction holes are evenly spaced diagonally downward on the inner side of the negative pressure liquid suction tube 5. The negative pressure liquid suction tube 5 is connected to an external negative pressure suction device. A flushing tube 6 is provided through the top of the protective cover 1 to achieve the purpose of isolating and protecting the fistula and providing negative pressure drainage and flushing.

[0033] Among them, an elliptical cover 2 is provided on the top of the protective cover 1, the elliptical cover 2 is connected to the protective cover 1, and a support tube 3 passes through the elliptical cover 2 to assist the protective cover 1 to be adsorbed on the patient's body;

[0034] Among them, the protective cover 1 is provided with an extension ring 7 at the lower part of the outer side, and a plurality of arc-shaped negative pressure chambers 8 with bottom openings are evenly spaced on the extension ring 7. The negative pressure chambers 8 all pass through the extension ring 7. A connecting pipe 9 is provided between the tops of all the negative pressure chambers 8. The connecting pipe 9 is connected to each negative pressure chamber 8. A first connecting pipe 10 is provided on the upper part of the connecting pipe 9. The first connecting pipe 10 is connected to an external air pump and is used to adsorb the patient's body through the negative pressure chamber 8 to assist in fixing the protective cover 1 on the patient's body.

[0035] The lower part of the support tube 3 is provided with a cushioning mechanism 11 for shaping the intestinal components around the fistula.

[0036] For example, when in use, the medical staff first tailors the blocking piece 4 according to the size of the fistula and the course of the intestinal tract at the fistula according to the different conditions of the patient, inserts it from the fistula, and gently lifts it to the outside of the fistula to block the fistula. At the same time, the protective cover 1 surrounds the fistula and covers it. Then, the elliptical cover 2 is gently pressed against the fistula to form appropriate pressure and tightness so that it is not easy to loosen. In this way, the flushing tube 6 and the negative pressure suction tube 5 are used to flush and drain the leaked intestinal fluid, keep the granulation tissue around the fistula moist and relatively clean, promote the healing of the wound tissue around the small intestinal air fistula, connect the outside world and the small intestine through the support tube 3, restore the intestinal continuity in time, and give the patient the first time. Enteral nutrition is used to provide conditions for definitive surgery. After the protective cover 1 is placed, the negative pressure chamber 8 is pressed against the patient's skin by pressing the extension ring 7, and then the external air pump is started to evacuate the negative pressure chamber 8 through the first connecting tube 10, so that negative pressure is formed in the negative pressure chamber 8. Finally, multiple negative pressure chambers 8 also have an adsorption effect on the patient's skin, which helps the protective cover 1 to be better fixed on the patient's body. In this way, even if the negative pressure between the protective cover 1 and the small intestinal air fistula tissue is small, the protective cover 1 can be prevented from falling off the patient, thereby achieving the purpose of stably fixing the protective cover 1 on the human body and ensuring that the intestinal tissue near the fistula opening will not deform and bulge into the inside of the protective cover 1.

[0037] like Figure 4 and Figure 5 As shown, in this embodiment, the cushion pressing mechanism 11 specifically further includes a sealing air cushion 1101, a connecting frame 1102, a second connecting pipe 1103, a branch pipe 1104 and an extrusion pipe 1105;

[0038] A sealing air cushion 1101 is provided in the middle of the top of the sealing piece 4. The sealing air cushion 1101 has a mesh-like raised pattern on one side close to the center of the protective cover 1, which is used to assist the sealing piece 4 in sealing the fistula.

[0039] Among them, a connecting frame 1102 is provided at the lower part of the support tube 3 and below the flushing tube 6. The connecting frame 1102 is connected to the blocking air cushion 1101. The upper part of the connecting frame 1102 is connected to a second connecting pipe 1103. The second connecting pipe 1103 passes through the elliptical cover 2 upward. The two ends of the second connecting pipe 1103 are respectively connected to the connecting frame 1102 and an external air pump for inflating the blocking air cushion 1101 and the branch pipe 1104.

[0040] Among them, a plurality of branch tubes 1104 are evenly spaced in a ring shape on the outer side of the upper part of the connecting frame 1102, and the branch tubes 1104 are connected to the connecting frame 1102. A wavy annular extrusion tube 1105 is connected between the ends of the branch tubes 1104 away from the connecting frame 1102. The wavy annular extrusion tube 1105 and the mesh raised patterns of the sealing air cushion 1101 correspond to each other in shape after inflation, and are used to work together with the sealing air cushion 1101 to shape and position the small intestinal tissue around the fistula.

[0041] In the initial state, there is no air in the sealing cushion 1101, the branch tube 1104 and the squeeze tube 1105. When the sealing piece 4 is inserted into the small intestine from the fistula, the sealing cushion 1101 is also squeezed and deformed and sent into the small intestine, the branch tube 1104 is bent, and the squeeze tube 1105 is isolated from the small intestine. After the sealing piece 4 is sealed, air is ventilated into the connecting frame 1102 through the second connecting tube 1103, the sealing cushion 1101 is inflated, and the branch tube 1104 and the squeeze tube 1105 are connected. 105 is also inflated, and the small intestinal wall is clamped between the extrusion tube 1105 and the sealing air cushion 1101, covering the small intestinal air fistula tissue in the middle of the annular extrusion tube 1105. In this way, the extrusion tube 1105 and the sealing air cushion 1101 are squeezed and fixed, further preventing the intestinal tissue near the fistula from deforming and protruding into the inside of the protective cover 1. At the same time, the wavy extrusion tube 1105 and the mesh raised pattern of the sealing air cushion 1101 are fitted together, which can also assist the sealing piece 4 in sealing the fistula.

[0042] Example 2

[0043] like Figure 6 and Figure 7 As shown, on the basis of Example 1, a separation mechanism 12 is specifically included. The separation mechanism 12 specifically includes a limit ring 1201, a guide column 1202, a sealing plate 1203 and a mosaic block 1204. A limit ring 1201 is provided on the lower inner side of the negative pressure chamber 8, and guide columns 1202 are provided on the horizontal side walls of the negative pressure chamber 8. A sealing plate 1203 is provided on the inner side of the negative pressure chamber 8 to slide up and down. The sealing plate 1203 is provided with a mosaic block 1204 near the guide column 1202, and the mosaic block 1204 is slidably matched with the guide column 1202.

[0044] The sealing plate 1203 in the negative pressure chamber 8 is initially at the top of the limiting ring 1201, and there is air in the space formed by the sealing plate 1203 and the inside of the negative pressure chamber 8. When the negative pressure chamber 8 is in contact with the patient's skin and the negative pressure chamber 8 is evacuated through the first connecting tube 10, the air pressure in the space between the sealing plate 1203 and the negative pressure chamber 8 decreases, and 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 then close to the patient's skin. In this way, the first connecting tube 10 and the human body are isolated in the negative pressure chamber 8 by the sealing plate 1203. Even if a negative pressure chamber 8 leaks due to not being in close contact with the patient, it will not affect other negative pressure chambers 8. In the above process, the guide column 1202 and the mosaic block 1204 guide the movement of the sealing plate 1203.

[0045] like Figure 8 and Figure 9 As shown, it also includes a guiding mechanism 13, which specifically includes a first elastic strip 1301, a fixing ring 1302 and a second elastic strip 1303. The first elastic strip 1301 is provided on the upper side wall inside the branch tube 1104. When the first elastic strip 1301 is straightened, it is concave and fits the branch tube 1104. When it is not straightened, it is in a wound state along the length direction. The first elastic strip 1301 is provided with fixing rings 1302 at both ends along the length direction, and the second elastic strip 1303 is provided in the middle of the first elastic strip 1301.

[0046] When the branch tube 1104 is not inflated and stretched, the second elastic strip 1303 is in a state of being stretched 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 stretched. Since the first elastic strip 1301 is in a state of being wound along the length direction of the first elastic strip 1301 when it is not stretched, and the two ends of the first elastic strip 1301 are bent and fixed by the fixing ring 1302, the first elastic strip 1301 will bend and fold at the connection between the first elastic strip 1301 and the second elastic strip 1303 in this state, and the branch tube 1104 drives the extrusion tube 1105 to lift upward under the action of the first elastic strip 1301, so as to avoid affecting the placement of the blocking piece 4 and the blocking air cushion 11 01, and after the branch tube 1104 is inflated, the branch tube 1104 gradually straightens, and the first elastic strip 1301 is straightened and formed into a concave shape fitting the branch tube 1104 under the drive of the branch tube 1104, and the second elastic strip 1303 is bent and deformed again along the length direction of the second elastic strip 1303. During the whole process, the bending and straightening of the branch tube 1104 only occur within the upper and lower ranges under the action of the first elastic strip 1301, and will not deviate in the horizontal direction, so as to avoid the displacement and misalignment of the extrusion tube 1105 and the mesh raised patterns of the sealing air cushion 1101, and after the branch tube 1104 is straightened, the first elastic strip 1301 can also play the role of a skeleton, providing auxiliary support for the branch tube 1104.

[0047] like Figure 10 and Figure 11 As shown, it also includes a limiting mechanism 14, which specifically includes a connecting ring 1401, a rotating ring 1402 and a counterweight 1403. The connecting ring 1401 is provided at the end where the elliptical cover 2 and the protective cover 1 are close to each other, and a rotating ring 1402 is rotatably provided between the connecting ring 1401 of the elliptical cover 2 and the protective cover 1. A groove is provided on the inner side of the rotating ring 1402 to limit the flushing pipe 6, and a counterweight 1403 is provided on the outer side of the rotating ring 1402 away from the flushing pipe 6; a shaping wire 1404 is provided inside the flushing pipe 6.

[0048] When flushing the fistula, medical staff or patients can manually control the rotating ring 1402 to rotate the flushing tube 6 around the support tube 3, so that it can better flush the area around the fistula. When the patient sits up or turns his body, the counterweight 1403 can drive the rotating ring 1402 to rotate, so that the counterweight 1403 drives the flushing tube 6 to remain above the fistula, avoiding the flushing tube 6 from being unable to flush the fistula due to gravity. The shaping wire 1404 in the flushing tube 6 can fix the shape of the flushing tube 6 to avoid the flushing tube 6 from being deformed due to gravity.

[0049] like Figure 12 As shown, a sealing sheet 15 is also included. The bottom of the protective cover 1 is provided with an annular sealing sheet 15 that expands outward from top to bottom. The vertical cross-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 fit closely to the human body when the negative pressure between the protective cover 1 and the human body is small, thereby forming a better sealing structure and allowing the protective cover 1 to be better adsorbed on the patient's body.

[0051] The first connecting tube 10 is inserted into the pipeline connecting the negative pressure liquid suction tube 5 and the external negative pressure aspirator.

[0052] The first connecting tube 10 passes through the pipe connecting the negative pressure suction tube 5 and the external negative pressure aspirator, and then passes out to connect with the external air pump. This can reduce the number of exposed pipes and avoid entanglement between pipes that affects the normal use of the device.
