Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to a stool drainage kit. Background Art

[0002] Fecal incontinence is a common nursing problem in clinical nursing work, and is more common in critically ill, bedridden and elderly patients. Feces can irritate the skin around the anus, and the skin around the anus and perineum is kept moist for a long time. Coupled with the friction of the skin, these factors make the local skin very prone to redness, swelling and ulceration, which seriously affects the patient's quality of life, not only causing great pain to the patient, but also bringing many difficulties to nursing work.

[0003] At present, the conventional measures for patients with fecal incontinence are mainly timely skin management. For those with watery stools, ostomy bags are attached to the anus or anal canal for drainage. In severe cases, antidiarrheal drugs can be given according to the doctor's advice. For patients who are bedridden for a long time and have fecal incontinence, conventional treatment methods are used. Although the patient's skin can be temporarily relieved, repeated application of the skin protection film will increase the difficulty of cleaning and the workload of nursing staff. The ostomy bag or anal canal is easy to fall off when the patient turns over or other operations that require moving the body position, resulting in stool overflow and soaking the skin, which can also lead to an increase in the patient's economic costs.

[0004] In order to improve the nursing difficulty of patients with fecal incontinence, in the related technology, there is a fecal drainage device for drainage of feces. For example, the Chinese patent document with the authorization announcement number CN 2917593Y discloses a fecal incontinence drainage device, which is provided with an anal canal, a drainage tube and a loose stool belt. The anal canal and the drainage tube are connected. The loose stool belt and the drainage tube are detachably connected for easy replacement. An air bag is provided on the anal canal. After the anal canal is inserted into the patient's body, the air bag is inflated to fill the air bag. After the air bag is filled, the fixation of the anal canal is more reliable. However, in actual use, due to the uncertainty of manual operation, the air bag is prone to tilt during insertion, and the sealing performance is reduced; and due to the transverse wrinkles of the intestine caused during the insertion process, the tightness of the intestine will be different when the air bag is opened, which is easy to cause discomfort to the patient and a poor experience.

[0005] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0043] like Figures 1 to 10 As shown, a stool drainage kit provided by an embodiment of the present invention includes a drainage tube 100 , a drainage bag 200 , an inflation tube 400 and an adjustment component 300 .

[0044] The drainage tube 100 has an insertion end and a collection end. The insertion end is fixedly provided with an airbag 110. The center of the airbag 110 has a through hole, which is connected to the inner cavity of the drainage tube 100. When in use, the insertion end is inserted into the intestine through the anus to drain the excrement in the intestine outward. The drainage bag 200 is connected to the collection end of the drainage tube 100 to collect the intestinal excrement discharged from the drainage tube 100. The inflation tube 400 is provided on the drainage tube 100 and is connected to the airbag 110. The medium can be charged and discharged into the airbag 110 through the inflation tube 400 to make the airbag 110 0 filling or contraction; the adjusting component 300 is arranged inside the drainage tube 100 and acts on the airbag 110. The adjusting component 300 is configured to be able to adjust the posture of the airbag 110 in the intestine so that the airbag 110 is parallel to the cross-section of the intestine, thereby making the seal between the airbag 110 and the intestine more reliable. At the same time, during the process of adjusting the posture of the airbag 110, the squeezing point with the inner wall of the intestine is continuously changed, so that the wrinkles on the inner wall of the intestine caused by the insertion of the drainage tube 100 can be eliminated, thereby further improving the sealing performance and improving the patient's use experience.

[0045] In a further embodiment, the adjustment assembly 300 includes an internal gear 310, a flexible tube 320 and a rotating block 330; the drainage tube 100 includes a soft tube 101 and a hard tube 102 connected to each other, the soft tube 101 is connected to the drainage bag 200, the hard tube 102 is connected to the airbag 110, and the internal gear 310 is arranged on the inner wall of the hard tube 102.

[0046] The flexible tube 320 has a certain elasticity and can be deformed. For example, the flexible tube 320 can be made of rubber material. The flexible tube 320 is inserted into the drainage tube 100. The initial cross-sectional shape of the flexible tube 320 is circular. The outer diameter of the flexible tube 320 is smaller than the inner diameter of the hard tube 102. The flexible tube 320 includes a connected transmission gear tube 321 and an extrusion tube 322. The transmission gear tube 321 is located in the hard tube 102, and the extrusion tube 322 is located in the through hole in the center of the airbag 110. The outer peripheral wall of the transmission gear tube 321 is provided with teeth that are adapted to the internal gear 310.

[0047] The rotating block 330 is rotatably inserted into the flexible tube 320. The rotating block 330 has a long axis. Both ends of the long axis of the rotating block 330 can press the inner wall of the flexible tube 320 to deform the flexible tube 320 and engage with the internal gear 310 to drive the flexible tube 320 to rotate during the rotation process.

[0048] Specifically, the cross-sectional shape of the rotating block 330 perpendicular to the axis of the flexible tube 320 can be a racetrack shape or an elliptical shape, and the present invention preferably has a racetrack shape. During the rotation of the rotating block 330, the two ends of the long axis of the rotating block 330 continuously press against the flexible tube 320, so that the flexible tube 320 is deformed and forms a moving deformation wave, and the position where the transmission gear tube 321 of the flexible tube 320 is pressed by the long axis of the rotating block 330 meshes with the internal gear 310, thereby realizing the rotation of the flexible tube 320. During the rotation of the flexible tube 320, its squeezing tube 322 pushes the airbag 110, so that the airbag 110 continuously adjusts its posture. If one end of the airbag 110 is higher than the other end during the insertion process, and is not parallel to the cross section of the intestine, during the process of the airbag 110 continuously adjusting its posture, the airbag 110 is gradually straightened and rotates in a direction close to the cross section of the intestine, and finally parallel to the cross section of the intestine. At the same time, as the flexible tube 320 continuously rotates to change the posture of the airbag 110, the extrusion point of the flexible tube 320 on the intestinal inner wall continuously changes, which will not cause continuous friction between the airbag 110 and the intestinal inner wall, and can eliminate intestinal wrinkles caused by the device insertion process.

[0049] In a further embodiment, a rotating rod 331 is connected to the rotating block 330, the rotating rod 331 extends out of the drainage tube 100 and is rotationally sealed with the drainage tube 100. Manually driving the rotating rod 331 to rotate can drive the rotating block 330 to rotate. A handle is provided at the end of the rotating rod 331 to facilitate driving the rotating rod 331. In one embodiment, the rotating block 330 is fixedly connected to the rotating rod 331. In another embodiment, the present invention preferably connects the rotating block 330 to the rotating rod 331 detachably, specifically, a threaded connection can be adopted, so that the rotating rod 331 can be removed from the rotating block 330. In this embodiment, the stool drainage kit of the present invention further includes a sealing plug (not shown in the figure), which can seal the hole on the drainage tube 100 for passing the rotating rod 331 after the rotating rod 331 is removed from the rotating block 330.

[0050] In a further embodiment, in order to facilitate the discharge of excrement, the rotating block 330 is a thin-walled part, which is hollow inside and open at both ends. A mounting plate is arranged at the center of the rotating block 330, and the rotating rod 331 is arranged on the mounting plate.

[0051] In a further embodiment, a flushing tube 500 is also provided on the drainage tube 100, and the flushing tube 500 extends to the front end of the airbag 110. By injecting water into the flushing tube 500, the excrement on the inner wall of the intestine can be flushed, which further facilitates the discharge of the excrement. In order to enhance the flushing ability of the device, a plurality of flushing tubes 500 can be provided, and only one is shown in the drawings of the present invention. It can be understood that the ends of the flushing tube 500 and the inflation tube 400 located outside the drainage tube 100 are closed, and an injection port is provided, and the injection port can be connected to a syringe, and the airbag 110 is inflated and deflated by the syringe, or water is injected into the intestine. Further, a rubber plug can be fixedly provided at the end of the flushing tube 500 and the inflation tube 400, and the injection port is provided on the rubber plug. Under the contraction of the rubber plug, the injection port is in a sealed state, and an openable blocking cover can also be provided at the injection port, and the injection port is opened or closed by operating the blocking cover.

[0052] Furthermore, the drainage tube 100 is provided with a first channel 103 and a second channel 104, the first channel 103 connects the airbag 110 and the inflation tube 400, the second channel 104 extends to the front end of the airbag 110, one end of the second channel 104 extending to the front end of the airbag 110 is connected to the outside world, and the other end is connected to the flushing tube 500.

[0053] In a further embodiment, referring to Figure 1 The drainage bag 200 is provided with an external thread interface 210 , and the collecting end of the drainage tube 100 is provided with an internal thread interface 120 . The internal thread interface 120 and the external thread interface 210 are threadedly matched to realize the connection between the drainage bag 200 and the drainage tube 100 .

[0054] In combination with the above embodiments, the use principle and working process of the present invention are as follows:

[0055] In the initial state, the airbag 110 is in a contracted state. When in use, first, the insertion end of the drainage tube 100 is inserted into the intestine through the anus. After being inserted in place, the airbag 110 is inflated through the inflation tube 400. During the inflation process, the rotating rod 331 is rotated, and the rotating rod 331 drives the rotating block 330 to rotate. The rotating block 330 continuously squeezes the flexible tube 320, causing the flexible tube 320 to deform, providing a moving deformation wave for the flexible tube 320. During the deformation and movement process of the flexible tube 320, it continuously meshes with the internal gear 310, thereby The rigid tube 102 rotates internally, and during the deformation and rotation of the flexible tube 320, the squeezing tube 322 pushes the airbag 110, so that the airbag 110 continuously adjusts its posture. If the airbag 110 is not parallel to the cross section of the intestine at this time, under the push of the squeezing tube 322, the airbag 110 continuously rotates in a direction close to the cross section of the intestine, and is gradually straightened. In the process of the deformation and rotation of the flexible tube 320, the squeezing point of the flexible tube 320 on the inner wall of the intestine continuously changes, and the intestinal folds caused by the insertion of the device on the inner wall of the intestine are eliminated. After the airbag 110 is inflated and fully expanded, the rotating rod 331 can be continuously rotated to fine-tune the posture of the airbag 110 to complete the basic fixation of the intestine. After that, the rotating rod 331 can be removed, and the hole on the drainage tube 100 for installing the rotating rod 331 can be sealed with a sealing plug, and the device can be used normally. During use, water is injected into the intestine through the flushing tube 500 to facilitate the smooth discharge of excrement into the drainage bag 200 through the drainage tube 100. After a certain amount of excrement accumulates in the drainage bag 200, a new drainage bag 200 can be replaced. When the present invention needs to be removed from the patient, air is pumped out through the inflation tube 400 to shrink the airbag 110, and the drainage tube 100 can be removed.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
