DETAILED DESCRIPTION

[0023] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0024] As shown in the accompanying Figure 1 to the accompanying Figure 8 drawings:

[0025] Example one:

[0026] The present application provides a suction device sleeve which can rotate to adjust the opening degree of side hole, comprising a suction outer tube 4, which is used for clinical intestinal obstruction decompression treatment, further comprising: a main body mechanism, which is clamped and connected to the suction outer tube 4, and is used for cooperating with the suction outer tube 4 to perform negative pressure suction, the main body mechanism comprises a suction tube 3 clamped and connected to one end of the suction outer tube 4; an adjusting mechanism, which is arranged in the suction outer tube 4, and is used for adjusting the use of the suction outer tube 4, the adjusting mechanism comprises a suction inner tube 8 rotatably arranged in the suction outer tube 4, the suction outer tube 4 is integrally formed with a suction head 5, and a plurality of suction hole one 7 are formed in the suction head 5; a connecting mechanism, which is arranged on the suction outer tube 4 and the suction inner tube 8, and is used for rotatably arranging the suction outer tube 4 and the suction inner tube 8, the connecting mechanism comprises a plurality of limiting rings 12 fixedly arranged on the inner wall of the suction outer tube 4, and a plurality of limiting grooves 14 are formed in the outer wall of the suction inner tube 8; a sealing mechanism, which is arranged on the suction inner tube 8, and is used for sealingly connecting the suction outer tube 4 and the suction inner tube 8, the sealing mechanism comprises a sealing ring 16 fixedly arranged at the bottom of the suction inner tube 8;

[0027] Meanwhile, in the clinical intestinal obstruction decompression treatment, the rotating adsorption inner tube 8 is used to adjust the coincidence degree of the suction hole two 9 or the suction hole three 10 on the adsorption outer tube 4 and the suction hole one 7 on the adsorption outer tube 4, so that the side hole opening degree is flexibly adjusted. In use, the adsorption outer tube 4 is placed in the patient's intestinal tract, the suction hole one 7 on the adsorption head 5 is aligned with the corresponding hole position of the adsorption inner tube 8, then the negative pressure adsorption system is formed by connecting the suction tube 3, the suction bottle 2 and the negative pressure suction device 1, the adsorption inner tube 8 is rotated by rotating the connecting tube 6, the elastic arc piece 13 is fixed at an angle in cooperation with the limiting port 11, and the sealing ring 16 and the sealing ring 15 ensure the sealing property in the rotating process. The advantage is that the hole diameter can be flexibly selected according to the viscosity of the intestinal contents and the obstruction condition: when the suction hole two 9 and the suction hole one 7 are completely coincident, it is suitable for sucking off viscous or blocky contents, when the suction hole three 10 and the suction hole one 7 are coincident, a smaller hole diameter is formed to avoid adsorption damage to the intestinal mucosa, improve the operation safety and adaptability, and the design enhances the versatility and operation convenience of the instrument, effectively solving the problems of unadjustable side hole of the traditional suction device and inconvenient use.

[0028] Reference Figure 1 and Figure 2 The main body mechanism includes the adsorption outer tube 4, the suction tube 3, the suction bottle 2 and the negative pressure suction device 1.

[0029] By providing the adsorption outer tube 4, the adsorption outer tube 4 can be easily inserted into the body of the intestinal obstruction patient, and the patient is decompressed. The negative pressure suction device 1 is placed at the side of the adsorption outer tube 4, and the suction bottle 2 is fixedly connected to the negative pressure suction device 1. The suction tube 3 is fixedly connected to the adsorption outer tube 4. During use, the adsorption outer tube 4 can provide negative pressure from the negative pressure suction device 1, and the suction bottle 2 and the suction tube 3 are used to complete the decompression operation of the intestinal obstruction patient.

[0030] Example two:

[0031] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 The adjusting mechanism includes the adsorption head 5, the suction hole one 7, the adsorption inner tube 8, the suction hole two 9 and the suction hole three 10.

[0032] By integrally forming the adsorption head 5 on the adsorption outer tube 4, and opening a plurality of suction holes one 7 on the adsorption head 5, the adsorption head 5 can be inserted into the patient's body during use, and the plurality of suction holes one 7 can be used for intestinal obstruction adsorption and decompression in the patient's body. The adsorption inner tube 8 is rotatably connected inside the adsorption outer tube 4, and a plurality of suction holes two 9 are opened on the adsorption inner tube 8. When the adsorption outer tube 4 and the adsorption head 5 are used for intestinal obstruction decompression, the plurality of suction holes two 9 on the adsorption inner tube 8 correspond to the plurality of suction holes one 7 on the adsorption outer tube 4. At this time, the suction hole one 7 and the adsorption inner tube 8 are in the maximum aperture state. When different conditions of intestinal obstruction patients need to be decompressed, the use angle of the adsorption inner tube 8 can be rotated to make the overlapping aperture of the suction hole one 7 and the suction hole two 9 different, so as to adjust the aperture size between the suction hole one 7 and the suction hole two 9. In this way, it can adapt to different conditions of intestinal obstruction for decompression, and improve the use flexibility of the adsorption outer tube 4.

[0033] At the same time, the adsorption inner tube 8 is also provided with another structure, a plurality of suction holes three 10 are opened between the plurality of suction holes two 9, and the aperture of the suction hole three 10 is smaller than the aperture of the suction hole one 7. When different conditions of intestinal obstruction patients are used, the adsorption inner tube 8 can be rotated to make the suction hole two 9 coincide with the suction hole one 7, or the suction hole three 10 coincide with the suction hole one 7. When the suction hole two 9 coincides with the suction hole one 7, the apertures of the suction hole one 7 and the suction hole two 9 are the same, and the suction hole one 7 is in the maximum state. When the suction hole three 10 coincides with the suction hole one 7, the aperture of the suction hole one 7 is blocked by the suction hole three 10, and the aperture of the suction hole one 7 is reduced. In this way, it can adapt to different conditions of intestinal obstruction patients for use.

[0034] Secondly, when the plurality of suction holes one 7 on the adsorption head 5 are adjusted to a larger aperture, the larger aperture of the suction hole one 7 can more effectively suck out viscous fecal water, blocky contents or blood clots. When the plurality of suction holes one 7 on the adsorption head 5 are adjusted to a smaller aperture, the intestinal mucosa near the suction hole one 7 can be avoided to be strongly adsorbed, which can cause mucosal ischemia, edema, erosion, and even perforation.

[0035] Reference Figure 3 , Figure 5 and Figure 7 The connecting mechanism further comprises a connecting pipe 6, a limiting ring 12, a limiting groove 14, a limiting port 11 and an elastic arc piece 13.

[0036] The connecting pipe 6 is fixedly connected at the top of the adsorption inner pipe 8, so that the adsorption outer pipe 4 and the adsorption inner pipe 8 are conveniently clamped and connected with the suction pipe 3 through the connecting pipe 6, so as to complete the negative pressure adsorption work, and the connecting pipe 6 is rotated to conveniently complete the purpose of rotating adjustment of the adsorption inner pipe 8 in the adsorption outer pipe 4, and the side wall of the connecting pipe 6 is provided with friction lines, so as to facilitate the rotating operation of the adsorption inner pipe 8.

[0037] Meanwhile, a plurality of limiting rings 12 are fixedly connected to the inner wall of the adsorption outer pipe 4, a plurality of limiting grooves 14 are formed in the side wall of the adsorption inner pipe 8, and the limiting ring 12 is rotatably connected in the limiting groove 14, so that the adsorption inner pipe 8 is stably and rotatably connected in the adsorption outer pipe 4, and a plurality of limiting openings 11 are formed in the inner wall of the adsorption outer pipe 4, and a plurality of elastic arc pieces 13 are fixedly connected to the side wall of the adsorption inner pipe 8, so that when the connecting pipe 6 drives the adsorption inner pipe 8 to rotate and adjust in the adsorption outer pipe 4, the elastic arc piece 13 can be clamped in the limiting opening 11, so as to fix the rotating angle of the adsorption inner pipe 8, and when the adsorption outer pipe 4 is used in cooperation with the adsorption inner pipe 8 without the suction hole three 10, the elastic arc piece 13 does not need to be clamped in the limiting opening 11, and the elastic arc piece 13 can be supported between the inner wall of the adsorption outer pipe 4 and the outer wall of the adsorption inner pipe 8 as a soft material, without causing too large gap between the adsorption outer pipe 4 and the adsorption inner pipe 8.

[0038] Embodiment three:

[0039] Reference Figure 6 and Figure 8 The sealing mechanism comprises a sealing ring 16 and a sealing ring 15.

[0040] The sealing ring 16 is fixedly connected to the bottom of the adsorption inner pipe 8, so that when the adsorption inner pipe 8 is rotatably connected in the adsorption outer pipe 4, the bottom is sealingly and rotatably connected with the bottom of the adsorption outer pipe 4 through the sealing ring 16, so as to prevent leakage at the bottom of the adsorption inner pipe 8, and the sealing ring 15 is fixedly connected to the outer wall of the adsorption inner pipe 8 at the side of the plurality of suction holes two 9 and the suction hole three 10, so that when the suction hole two 9 and the suction hole three 10 on the adsorption inner pipe 8 are rotatably adjusted, the sealing ring 15 can seal and protect the gap between the inner wall of the adsorption outer pipe 4 and the outer wall of the adsorption inner pipe 8, so as to improve the use stability of the adsorption outer pipe 4 and the adsorption inner pipe 8.

[0041] Working principle: first, the adsorption head 5 at the front end of the adsorption outer tube 4 is inserted into the intestinal tract of the patient through the anus or intestinal stoma, so that the suction hole one 7 on it is aligned with the area to be suctioned, then, according to the nature of the intestinal contents (such as thin liquid, viscous fecal water or blocky contents) and the condition of the intestinal wall, the suction inner tube 8 is rotated by rotating the connecting tube 6 to adjust the overlapping state of the side holes: if a larger suction hole diameter is needed to suck viscous or solid contents, the suction inner tube 8 is rotated to make the suction hole two 9 completely overlap with the suction hole one 7, if a smaller hole diameter is needed to avoid damaging the intestinal mucosa or suctioning a thinner fluid, the suction inner tube 8 is rotated to make the suction hole three 10 overlap with the suction hole one 7, at this time, the effective suction hole diameter is reduced, during the adjustment process, the elastic arc piece 13 on the outer wall of the suction inner tube 8 will be clamped into the limiting port 11 on the inner wall of the adsorption outer tube 4, realizing angle fixation and ensuring the stability of the suction hole diameter, after the adjustment is completed, the suction tube 3 is connected with the tail end of the adsorption outer tube 4, and the other end is connected with the suction bottle 2 and the negative pressure suction device 1 in turn, the negative pressure suction device 1 is started, and the targeted suction operation can be carried out, the advantages of the device are that the side hole opening degree can be flexibly and continuously adjusted, the suction hole one 7 and the suction hole two 9 or the suction hole three 10 can be combined to different degrees by rotating the suction inner tube 8, so as to adapt to diversified clinical needs: the larger hole diameter mode can efficiently remove viscous feces, blood clots or semi-solid obstruction, improve the suction efficiency, and the smaller hole diameter mode can significantly reduce the adsorption force on the intestinal mucosa, prevent iatrogenic damage such as mucosal ischemia, edema and even perforation caused by excessive negative pressure, and improve the safety of operation, in addition, the suction inner tube 8 is stably rotated through the cooperation of the limiting ring 12 and the limiting groove 14, and the sealing ring 16 and the sealing ring 15 ensure the sealing property of the rotating joint between the inner and outer tubes, prevent leakage and maintain stable negative pressure, the overall structure design takes into account the adjustment convenience, operation stability and clinical adaptability, effectively solves the limitation that the side hole of the traditional suction device sleeve cannot cope with complex intestinal content properties, improves the precision and safety of intestinal obstruction decompression treatment.

[0042] The foregoing merely describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present application.
