Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an anorectal balloon drainage device. Background Art

[0002] Two remarkable characteristics of anorectal surgeries (including hemorrhoid surgeries and anal fistula surgeries) are: openness and contamination. That is, in the case where the surgical wound is not sutured or sutured poorly, feces and / or intestinal secretions are likely to contaminate the wound surface. Common complications include bleeding, infection, pain and edema, and anal stenosis. Among them, pain and edema are likely to cause infection and make it difficult for the wound to heal. In addition, the tearing of the wound caused by dressing change and defecation is likely to cause massive bleeding.

[0003] Currently, anorectal surgeons often use self-made devices to avoid the above problems, such as urinary catheter balloons, vaseline gauze strips, etc. However, through long-term practical tests, these self-made devices have defects such as no standard, instability, uncertain treatment effect, obvious discomfort, and difficulty for patients to tolerate. Content of the Utility Model

[0004] In order to solve the above problems, the utility model discloses an anorectal balloon drainage device, which can effectively prevent or reduce postoperative complications and promote the rapid healing of the wound surface. The specific technical solution of the utility model is as follows:

[0036] In order to enable those skilled in the art to better understand the technical solutions of the utility model, the following further detailed description of the utility model is made in conjunction with the specific embodiments.

[0037] As Figure 1 shown, an anorectal balloon drainage device includes a drainage tube 1, the drainage tube 1 is a hollow structure, one end thereof is a drainage end 2, and the other end is a connection end 3; the drainage tube 1 is sequentially provided with an outer balloon 4 and at least one inner balloon from the connection end 3 to the drainage end 2; the drainage tube 1 is provided with a first channel for communicating the outer balloon 4 and at least one inner balloon, and a second channel for communicating to the patient's rectum.

[0038] In the use of this embodiment, the outer balloon 4 is located outside the human body, and the inner balloon is located inside the human body. Since the drainage tube 1 is provided with a first channel for communicating the outer balloon 4 and at least one inner balloon, medical staff can fill or discharge the filling medium into the outer balloon 4 and the inner balloon through the first channel to achieve the fixation of the drainage device. The filling medium is generally gas, liquid, ice saline, etc. Among them, when using ice saline, it can also achieve cold compress and swelling reduction of the wound surface. Further, in the outer balloon 4 and the inner balloon, each balloon is communicated with an independent first channel. That is to say, in this embodiment, the outer balloon 4 and the inner balloon can be independently inflated and compressed. Therefore, in the specific use process, medical staff can choose to fill or discharge the filling medium into the outer balloon 4 and / or the inner balloon according to actual needs. Of course, in some other technical solutions of this embodiment, all the outer balloons 4 and the inner balloons can also be communicated through a single first channel. At this time, the outer balloon 4 and the inner balloon are filled or discharged with the filling medium at the same time. Although it is convenient to use, compared with the technical solution of this embodiment, the operation freedom is not high.

[0039] In this embodiment, the second channel includes a first sub-channel for communicating with the rectum ampulla region of the patient and a second sub-channel for communicating with the anal canal of the patient. Further, the at least one inner balloon includes a first inner balloon 5 and a second inner balloon 6 sequentially arranged on the drainage tube 1 from the connection end 3 to the drainage end 2; the first sub-channel is provided with a first inlet 7, and the first inlet 7 is located between the second inner balloon 6 and the drainage end 2 of the drainage tube 1; the second sub-channel is provided with a second inlet 8, and the second inlet 8 is located between the first inner balloon 5 and the second inner balloon 6. Thus, in the specific process of using this embodiment, first, a filling medium is injected into the outer balloon 4, the first inner balloon 5, and the second inner balloon 6 through the first channel. After the outer balloon 4, the first inner balloon 5, and the second inner balloon 6 are initially inflated, the drainage tube 1 is initially fixed near the anus. Then, necessary flushing and drug administration are carried out through the first inlet 7 and the second inlet 8, and then the filling medium is continuously injected into the first inner balloon 5 and the second inner balloon 6, so that the first inner balloon 5 and the second inner balloon 6 are inflated to the optimal state. Then, the filling medium is injected into the outer balloon 4 to make the outer balloon 4 inflated to the optimal state to achieve the fixation of the drainage device. It can be known that in the above process, precise drug administration, flushing, compression hemostasis, or cold compress and swelling reduction of the corresponding part can be achieved. It should be noted that the connection end 3 can be connected to a drainage bag or the like to effectively centrally manage and dispose of the substances drained out of the body through the drainage end. It can also be known from this that in the first channel and the second channel, any one of the channels is connected to an external device through a connecting tube 11. The external device includes a driving device for the filling medium, as well as a drug administration device and a flushing device. Generally speaking, the connecting tube 11 is preferably a flexible tube. Further, the connecting tube 11 is provided with a check valve 9. The check valve 9 can effectively prevent liquid leakage and air leakage, ensure the state of the outer balloon 4, the first inner balloon 5, and the second inner balloon 6 inflated by the filling medium, and at the same time can also ensure the stability of drug administration and cleaning.

[0040] It should be noted that when the outer balloon 4, the first inner balloon 5, and the second inner balloon 6 are inflated with the filling medium, a fixing tension that pulls on each other will be formed, thereby preventing the drainage tube 1 from sliding back and forth in the patient's body, thus meeting the fixation requirements. Thus, this embodiment has the advantage of being easy to fix. On this basis, a gauze can be placed outside to absorb exudate, which is convenient for patient care.

[0041] In this embodiment, the inner balloon 5 fits against the inner wall of the anal canal in the filled state; the cross-section of the inner balloon 6 in the filled state is circular or concave or tends to be circular. Generally speaking, the inner balloon 5 is a columnar balloon that conforms to the length and diameter of the anal canal, or has a spindle-shaped structure. After the inner balloon 6 is placed in the rectal ampulla area and filled with a filling medium, it is specifically spherical or spherical with a concave part or tends to be spherical. The diameter of the inner balloon 6 in the filled state ensures sufficient contact with the intestinal wall and completely covers the inner balloon 5 placed in the anal canal, and they can contact each other, thereby preventing fecal overflow and subsequent contamination of the wound. In other words, in the filled state of the inner balloon 5 and the inner balloon 6, on the radial projection plane of the drainage tube 1, the projection of the inner balloon 5 is located within the projection of the inner balloon 6. And in the filled state of the inner balloon 5 and the inner balloon 6, when the inner balloon 5 and the inner balloon 6 contact each other, it can better prevent and reduce postoperative complications of anorectal diseases and promote rapid wound healing. In particular, as Figure 2 shown, when the inner balloon 6 is specifically spherical with a concave part, it is also easy to collect excrement. Since the anal canal is innervated by the internal pudendal nerve, the pain sensation is sensitive. Therefore, when the inner balloon 5 matches the shape of the anal canal in the filled state, it can avoid irritating the intestinal wall. At this time, the contraction force of the sphincter can be used to effectively achieve compression hemostasis, so as to achieve full compression of the stenotic anal canal wall, effectively improve the tolerance of compression uniformity, and thus effectively reduce the pain of the wound surface and promote healing. In some embodiments, a hemostatic gauze can be arranged between the outer balloon 4 and the inner balloon 5.

[0042] In this embodiment, the drainage end 2 of the drainage tube 1 is provided with a decompression hole 10 communicating with the inside of the drainage tube 1. The decompression hole 10 has at least one, and all are located at a position of the drainage tube 1 close to the drainage end 2 and on the side wall of the drainage tube 1. It can realize the regulation of intestinal pressure, which is beneficial to smooth drainage, so as to further realize timely defecation and exhaust, and increase the patient's tolerance through effective decompression. In other words, the setting of the decompression hole 10 can realize auxiliary drainage.

[0043] Therefore, in this embodiment, the drainage device establishes a nursing channel connecting the patient's body and the outside, making the postoperative nursing operation simple and convenient, effectively preventing and reducing postoperative complications, and promoting rapid wound healing.

[0044] The above is only the preferred embodiment of the present invention. It should be noted that the above preferred embodiment should not be regarded as a limitation of the present invention. The protection scope of the present invention should be subject to the scope defined by the claims. For those of ordinary skill in the art in this technical field, without departing from the spirit and scope of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
