[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] The core of this invention is to provide an implantation device that can reliably and smoothly implant the drainage tube and indwelling balloon into the patient's rectum, reducing discomfort and pain and improving patient comfort.
[0034] The implantable device provided by this utility model includes a drainage tube 1, an indwelling balloon 2, and a guide 3. Please refer to [reference needed]. Figure 1 .
[0035] The drainage tube 1 has an implantation end and an exit end at its two ends, respectively. The implantation end is used to insert into the rectum, and the exit end is used for drainage. The exit end of the drainage tube 1 can be connected to a storage component such as a storage bag to collect the drained excrement. In specific applications, the implantation end is inserted into the patient's rectum, allowing the excrement in the rectum to be drained through the drainage end for fecal drainage in a semi-recumbent position.
[0036] The indwelling balloon 2 is connected to the periphery of the implantation end. The indwelling balloon 2 can be inflated to a limited or fixed state. Specifically, the inflation of the indwelling balloon 2 can be achieved by inflation, while the contraction can be achieved by deflation or aspiration. It can be used in combination with the existing clinical application of the indwelling balloon 2, which will not be elaborated here.
[0037] The guide 3 is located on the periphery of the drainage tube 1. The guide 3 is movable to limit the placement of the indwelling balloon 2 or to release the limitation on the indwelling balloon 2. Specifically, the guide 3 is a component that guides the indwelling balloon 2 and the implantation end of the drainage tube 1 into the patient's rectum. Guided by the guide 3, the indwelling balloon 2 can enter the rectum and then be inflated and fixed, reducing the patient's pain during the implantation process. Specifically, the guide 3 can adopt a tubular structure consistent with the drainage tube 1, or other shapes such as a frustum, as long as it facilitates entry into the rectum for its guiding function.
[0038] When the guide 3 moves to limit the indwelling balloon 2, the indwelling balloon 2 is inflated to a limiting state at this time, and in the limiting state, the guide 3 can drive the indwelling balloon 2 and the implantation end of the drainage tube 1 to extend into the rectum, and under the guidance, the indwelling balloon 2 and the implantation end enter the rectum. It should be noted that when the guide 3 enters the rectum, the indwelling balloon 2 is not in a full state, but in a state between the full state and the soft and collapsed state.
[0039] When the guide 3 moves to release the limitation of the indwelling balloon 2, the indwelling balloon 2 can be further inflated from the limiting state to a fixed state, and in the fixed state, the indwelling balloon 2 can be attached to the rectum to achieve fixation, so that the drainage tube 1 can be fixed and reliably and smoothly implanted into the rectum of the patient to ensure reliable drainage.
[0040] In the above process, after the indwelling balloon 2 and the implantation end of the drainage tube 1 are introduced into the rectum under the guidance of the guide 3, the indwelling balloon 2 is inflated to adhere to the rectum of the patient for fixation, thereby reducing the pain of patients with dry and hard stool, patients whose rectal end cannot accommodate the volume of the inflated balloon, patients with severe rectal anal canal stenosis, patients who have received rectal anastomosis, anal reconstruction, anal sphincter reconstruction within 6 weeks, patients with rectal wall integrity diseases, pregnant women, acute abdominal pain, gastrointestinal bleeding, etc. The implantation of the drainage tube 1 and the indwelling balloon 2 can be ensured to be smoothly implanted, and the use of the patient can be improved.
[0041] Based on the above embodiment, please refer to Figure 1 , Figure 5 , the guide 3 includes a limiting interval 31 and a pulling interval 32 in communication with the limiting interval 31, the limiting interval 31 is covered on the outer periphery of the indwelling balloon 2 to limit, and the pulling interval 32 is covered on the outer periphery of the implantation end to realize the movement of the guide 3 by pulling.
[0042] The specific limiting interval 31 can limit the indwelling balloon 2 in the limiting state, and the limiting interval 31 can limit in the form of limiting column, limiting block, boss, etc., which can reliably limit the inflated indwelling balloon 2 in the limiting state, so that the guide 3 can drive the indwelling balloon 2 and the drainage tube 1 to move synchronously when inserted into the rectum.
[0043] It should be noted that the indwelling balloon 2 in the limiting state can be attached to the limiting interval 31, or can not be attached to the limiting interval 31, as long as the indwelling balloon 2 can be reliably limited in the limiting interval 31.
[0044] The pulling interval 32 is arranged on the outer periphery of the implant end to realize the movement of the guide 3 by pulling, and specifically, the pulling interval 32 is arranged closer to the drainage end than the limiting interval 31 in use. The pulling interval 32 can be pulled or tugged manually to move the guide 3 as a whole, so that the limiting interval 31 releases the limitation on the indwelling balloon 2 in the limited state, and the indwelling balloon 2 can be inflated in the rectum and fixed therewith, and further, the guide 3 can be pulled to move to be separated from the drainage tube 1.
[0045] If the drainage tube 1 is connected with a receiving bag, the guide 3 is inconvenient to move directly to be separated from the drainage tube 1, and then the pulling interval 32 can be directly pulled to tear or directly cut to realize the separation of the guide 3 from the drainage tube 1.
[0046] On the basis of any of the above embodiments, the inner wall of the limiting interval 31 is provided with a plurality of limiting portions 311 arranged towards the axis of the limiting interval 31, and the plurality of limiting portions 311 are used to block the end portion of the indwelling balloon 2 close to the leading end.
[0047] Please refer to Figure 5 , the plurality of limiting portions 311 are specifically arranged along the inner wall of the limiting interval 31 in a uniform manner to reliably limit the end portion of the indwelling balloon 2 from the circumference, so that the indwelling balloon 2 and the drainage tube 1 can be followed synchronously into the rectum when the guide 3 moves to extend into the rectum, and play a reliable guiding role.
[0048] As shown in Figure 5 , the limiting portion 311 can be a boss capable of blocking the indwelling balloon 2.
[0049] In the embodiment, the limiting portion 311 is arranged in a plurality, which can be two, three or more, and can be flexibly arranged according to the actual size of the indwelling balloon 2.
[0050] On the basis of any of the above embodiments, please refer to Figure 5 , the outer periphery size of the limiting interval 31 is smaller than the outer periphery size of the pulling interval 32, and the outer periphery size of the pulling interval 32 gradually increases in the direction away from the limiting interval 31.
[0051] Specifically, the limiting interval 31 has a part entering the rectum, and thus the size is slightly smaller, while the pulling interval 32 does not need to enter the rectum, and thus the size is slightly larger for convenient pulling operation. The end portion of the pulling interval 32 away from the limiting interval 31 is the operation part, and thus the outer periphery size is set to the maximum.
[0052] In a specific embodiment, as Figure 5As shown, the pulling section 32 has a first area close to the limiting section 31 and a second area away from the limiting section 31, wherein the increasing speed of the outer circumferential dimension of the first area is less than that of the second area, which can facilitate the peeling of the guide 3 from the drainage tube 1 when the pulling operation is performed, and avoid the interference of the guide 3 with the normal drainage operation of the drainage tube 1.
[0053] In a specific embodiment, as shown in Figure 5 The outer circumference of the limiting section 31 can also be provided with a certain slope, specifically, the dimension gradually increases along the direction close to the pulling section 32, so that the limiting section 31 can have a sharp end when entering the rectum, facilitating the smooth entry of the limiting section 31 into the rectum.
[0054] On the basis of any of the above embodiments, please refer to Figure 1 , Figure 2 The guide 3 includes at least two monomers which are detachably connected, and the at least two monomers can be connected to cover the outer circumference of the drainage tube 1, or the at least two monomers can be disconnected to be detached relative to the drainage tube 1.
[0055] In a specific embodiment, the at least two monomers can be detachably connected by means of a hoop.
[0056] In a specific embodiment, the at least two monomers can be connected by a virtual line or a point broken line which is easy to tear.
[0057] Through the detachable connection of the at least two monomers, after the implantation end of the indwelling balloon 2 and the drainage tube 1 enters the rectum, the guide 3 can be moved to release the limiting of the limiting section 31 on the indwelling balloon 2, and after the limiting section 31 moves out of the rectum, the guide 3 can be peeled off from the drainage tube 1 by separating any two monomers of the at least two monomers, thereby realizing the detachment of the guide 3 relative to the drainage tube 1 without affecting the drainage operation of the drainage tube 1.
[0058] On the basis of any of the above embodiments, any two adjacent monomers are connected by a tearable line 34. When it is necessary to detach the guide 3 from the drainage tube 1, tearing is directly performed at the position of the pulling section 32 or the position of the limiting section 31, and under the action of the tearable line 34, the two adjacent monomers can be easily separated. After the guide 3 provides the guiding auxiliary function, the guide 3 can be directly torn off by tearing, which is simple and convenient to operate and has strong applicability.
[0059] In the present embodiment, the length of the tearable line 34 can be equal to or close to the axis length of the guide 3. When the length of the tearable line 34 is close to the axis length of the guide 3, one end of the tearable line 34 needs to extend to the edge of the limiting section 31 or the edge of the pulling section 32, so as to facilitate tearing.
[0060] On the basis of any of the above embodiments, please refer to Figure 5 One end of the tearable line 34 extends to the first end of the guide 3, and the other end of the tearable line 34 extends to the tearable slot 33 at the second end of the guide 3, and the tearable slot 33 is arranged close to the drainage end.
[0061] The tearable slot 33 can be a V-shaped slot, and the bottom of the slot is connected to the end of the tearable line 34, so that tearing from the position of the tearable slot 33 can easily and quickly separate the two adjacent monomers, improving the disassembly efficiency of the guide 3 relative to the drainage tube 1.
[0062] On the basis of any of the above embodiments, please refer to Figure 1 Further comprising an implant rod 5, the implant rod 5 is provided with a scale, when the indwelling balloon 2 is in the limiting state, the implant rod 5 can be inserted between the indwelling balloon 2 and the drainage tube 1 to the state of being unable to push, at this time the implant depth can be measured through the implant rod 5. The implant depth here specifically refers to the depth of the indwelling balloon 2 inserted into the rectum, through the measurement of the implant depth, the situation that the drainage tube 1 falls off due to insufficient insertion depth of the indwelling balloon 2 is avoided, and the health and comfort of the patient are avoided. Influence.
[0063] The zero scale of the implant rod 5 is arranged at the implant end, so that the depth of the indwelling balloon 2 inserted into the rectum can be directly obtained by reading the scale of the implant rod 5.
[0064] On the basis of any of the above embodiments, the outer periphery of the drainage tube 1 is provided with a contrast scale and / or a contrast scale, which is used to contrast with the scale of the implant rod 5 to obtain the implant depth. Through the scale contrast method, the depth of the implant end of the indwelling balloon 2 and the drainage tube 1 inserted into the rectum can be more accurately understood, the reliability of the implant is ensured on the premise of ensuring the smoothness of the implant, the situation that the components slide out of the rectum is avoided, and the comfort of the patient is improved.
[0065] Specifically, the contrast scale and / or the contrast scale can be used as a reference to determine whether the implant rod 5 is accurately inserted between the indwelling balloon 2 and the drainage tube 1, and whether the zero scale of the implant rod 5 is aligned with the end face of the indwelling balloon 2 away from the drainage end, to ensure the accuracy and effectiveness of the implant depth measurement.

The indication area 41 can be used to display the inflation state of the indwelling balloon 2, which is specifically in a half-filled state, a filled state or a soft collapsed state.
[0067] Next, the use process of the implant device provided in the application is described in detail:
[0068] Before implanting the anus, the gas in the implant end of the drainage tube 1 is extracted from the retention balloon 2, and then the retention balloon 2 and the drainage tube 1 are arranged in the guide 3, and then about half of the air is filled into the retention balloon 2 through the inflation assembly 4, so that the retention balloon 2 is inflated to the limiting state, and the retention balloon 2 is limited under the action of the limiting part 311;
