Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a fecal drainage kit. Background Technology

[0002] Fecal incontinence is a common nursing problem in clinical practice, especially among critically ill, bedridden, and elderly patients. Feces irritate the perianal skin, and the skin in the perianal and perineal area remains moist for extended periods. Combined with skin friction, these factors make the local skin highly susceptible to redness, swelling, and ulceration, severely impacting the patient's quality of life. This not only causes significant pain for the patient but also presents numerous challenges for nursing care.

[0003] Currently, the routine clinical measures for patients with fecal incontinence mainly involve timely skin management. For those with watery stools, ostomy bags are used to cover the anus or anal tubes for drainage. In severe cases, antidiarrheal medications may be administered as prescribed. For patients who are bedridden for extended periods and have fecal incontinence, while routine treatments may provide temporary relief, repeated application of protective skin film increases the difficulty of cleaning and the workload of nursing staff. Furthermore, ostomy bags or anal tubes are prone to dislodging during patient turning or other procedures requiring repositioning, leading to fecal leakage and skin maceration, which can also increase the patient's financial burden.

[0004] To improve the care of patients with fecal incontinence, some related technologies employ fecal drainage devices to drain stool. For example, Chinese patent document CN 2917593Y discloses a fecal incontinence drainage device. This device consists of an anal tube, a drainage tube, and a stool bag. The anal tube and drainage tube are connected, and the stool bag and drainage tube are detachably connected for easy replacement. An air bladder is installed on the anal tube. After the anal tube is inserted into the patient's body, the air bladder is inflated, making the anal tube more securely fixed. However, in actual use, due to the uncertainty of manual operation, the air bladder is prone to tilting during insertion, reducing the sealing performance. Furthermore, the transverse folds in the intestine caused during insertion can lead to uneven tightness of the intestine when the air bladder opens, easily causing discomfort and a poor patient experience.

[0005] The information disclosed in the background section of this invention is intended only to enhance the understanding of the general background of this invention and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention proposes a stool drainage kit to solve the problems of low sealing performance of existing stool drainage devices and easy intestinal folding during insertion.

[0007] The present invention provides a fecal drainage kit with the following technical solution: comprising:

[0008] The drainage tube has an insertion end and a collection end. An air bladder is fixedly installed at the insertion end. The air bladder has a through hole in the center, which communicates with the inner lumen of the drainage tube.

[0009] A drainage bag is attached to the collection end of a drainage tube and is used to collect intestinal waste discharged from the drainage tube.

[0010] An inflation tube is installed in the drainage tube and connected to the airbag. The inflation tube can be used to inflate or deflate the airbag.

[0011] An adjustment component, located inside the drainage tube and acting on the airbag, is configured to adjust the posture of the airbag within the intestine.

[0012] Optionally, the adjusting assembly includes an internal gear, a flexible tube, and a rotating block;

[0013] The drainage tube includes a soft tube and a rigid tube connected together. The soft tube is connected to the drainage bag, and the rigid tube is connected to the airbag. An internal gear is set on the inner circumferential wall of the rigid tube.

[0014] The flexible tube is elastic and can deform. The flexible tube is inserted into the drainage tube. The initial cross-sectional shape of the flexible tube is circular. The outer diameter of the flexible tube is smaller than the inner diameter of the rigid tube. The flexible tube includes a transmission tooth tube and a compression tube connected together. The transmission tooth tube is located inside the rigid tube, and the compression tube is located in the through hole in the center of the airbag. The outer peripheral wall of the transmission tooth tube is provided with teeth that are adapted to the internal gear.

[0015] The rotating block is inserted into the flexible tube. The rotating block has a long shaft. The two ends of the long shaft of the rotating block can press against the inner wall of the flexible tube to deform the flexible tube and mesh with the internal gear, so as to drive the flexible tube to form a moving deformation wave during rotation.

[0016] Optionally, the flexible tube is made of rubber.

[0017] Optionally, the cross-sectional shape of the rotating block perpendicular to the axis of the flexible tube is racetrack-shaped.

[0018] Optionally, the cross-sectional shape of the rotating block perpendicular to the axis of the flexible tube is elliptical.

[0020] Optionally, the rotating block is hollow inside and open at both ends, with a mounting plate at the center of the rotating block and a rotating rod mounted on the mounting plate.

[0021] Optionally, a flushing tube is provided on the drainage tube, which extends to the front end of the airbag.

[0022] Optionally, the ends of the flushing tube and the inflation tube located outside the drainage tube are closed and are provided with an injection port that can be connected to a syringe.

[0023] Optionally, the drainage bag is provided with an external threaded interface, and the collection end of the drainage tube is provided with an internal threaded interface, with the internal threaded interface and the external threaded interface being threadedly engaged.

[0024] The beneficial effects of the present invention are as follows: The stool drainage kit of the present invention has an adjustment component set in the drainage tube. The adjustment component adjusts the posture of the airbag in the intestine, straightens the airbag, and makes the position of the airbag parallel to the cross-sectional shape of the intestine, thereby improving the sealing between the airbag and the intestine. At the same time, during the process of adjusting the posture of the airbag, the pressure point with the inner wall of the intestine is constantly changing, so that the wrinkles on the inner wall of the intestine caused by the insertion of the drainage tube can be eliminated, further improving the sealing and improving the patient's user experience.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1 to 10 As shown, a fecal drainage kit provided in this embodiment of the 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. An air bladder 110 is fixedly mounted on the insertion end. The air bladder 110 has a through hole in its center, which communicates with the inner lumen of the drainage tube 100. In use, the insertion end is inserted into the intestine through the anus to drain intestinal waste. A drainage bag 200 is connected to the collection end of the drainage tube 100 to collect intestinal waste discharged from the drainage tube 100. An inflation tube 400 is located on the drainage tube 100 and communicates with the air bladder 110. The inflation tube 400 allows for the inflation of the air bladder 110 with a medium. 0. Filling or shrinking; The adjustment component 300 is disposed inside the drainage tube 100 and acts on the balloon 110. The adjustment component 300 is configured to adjust the posture of the balloon 110 in the intestine so that the balloon 110 is parallel to the cross section of the intestine, thereby making the seal between the balloon 110 and the intestine more reliable. At the same time, during the adjustment of the posture of the balloon 110, the pressure point with the inner wall of the intestine is constantly changing, so that the wrinkles on the inner wall of the intestine caused by the insertion of the drainage tube 100 can be eliminated, further improving the sealing performance and improving the patient's user experience.

[0045] In a further embodiment, the adjustment component 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 rigid tube 102 connected to each other, the soft tube 101 is connected to the drainage bag 200, the rigid tube 102 is connected to the airbag 110, and the internal gear 310 is disposed on the inner peripheral wall of the rigid tube 102.

[0046] The flexible tube 320 has a certain degree of elasticity and can be deformed. For example, the flexible tube 320 can be made of rubber. 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 rigid tube 102. The flexible tube 320 includes a transmission toothed tube 321 and a compression tube 322 connected to each other. The transmission toothed tube 321 is located inside the rigid tube 102, and the compression tube 322 is located in the through hole in the center of the airbag 110. The outer peripheral wall of the transmission toothed tube 321 is provided with teeth that are adapted to the internal gear 310.

[0047] The rotating block 330 is rotatably inserted inside the flexible tube 320. The rotating block 330 has a long shaft. The two ends of the long shaft of the rotating block 330 can press against the inner peripheral wall of the flexible tube 320 to deform the flexible tube 320 and mesh with the internal gear 310, so as to drive the flexible tube 320 to form a moving deformation wave during rotation.

[0048] Specifically, the cross-sectional shape of the rotating block 330 perpendicular to the axis of the flexible tube 320 can be either racetrack-shaped or elliptical, with the racetrack shape being preferred in this invention. During the rotation of the rotating block 330, both ends of its long axis continuously press against the flexible tube 320, causing the flexible tube 320 to deform and form a moving deformation wave. The position of the transmission gear tube 321 of the flexible tube 320 pressed against by the long axis of the rotating block 330 meshes with the internal gear 310, thereby enabling the flexible tube 320 to form a moving deformation wave. During the formation of this moving deformation wave, the compression tube 322 of the flexible tube 320 pushes the airbag 110, causing the airbag 110 to continuously adjust its posture. If, during insertion, one end of the airbag 110 is higher than the other, and it is not parallel to the intestinal cross-section, the airbag 110 is gradually straightened and rotated towards a direction parallel to the intestinal cross-section as the airbag 110 continuously adjusts its posture, eventually becoming parallel to the intestinal cross-section. Meanwhile, as the flexible tube 320 rotates continuously, causing the airbag 110 to change its posture, the pressure point of the flexible tube 320 on the intestinal wall changes continuously, preventing the airbag 110 from continuously rubbing against the intestinal wall and eliminating intestinal folds 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 rotatably 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 for easy driving. In one embodiment, the rotating block 330 and the rotating rod 331 are fixedly connected. In another embodiment, preferably, the rotating block 330 and the rotating rod 331 are detachably connected, specifically by a threaded connection, so that the rotating rod 331 can be detached from the rotating block 330. In this embodiment, the fecal drainage kit of the present invention also includes a sealing plug (not shown in the figure), which can seal the hole in the drainage tube 100 through which the rotating rod 331 passes after the rotating rod 331 is detached from the rotating block 330.

[0050] In a further embodiment, to facilitate the discharge of excrement, the rotating block 330 is a thin-walled part with a hollow interior and open ends. A mounting plate is provided at the center of the rotating block 330, and the rotating rod 331 is provided on the mounting plate.

[0051] In a further embodiment, the drainage tube 100 is also provided with a flushing tube 500, which extends to the front end of the airbag 110. By injecting water into the flushing tube 500, the excrement on the intestinal wall can be flushed, further facilitating the discharge of excrement. To enhance the flushing capability of the device, multiple flushing tubes 500 can be provided; only one is shown in the accompanying drawings of this invention. It is understood that the ends of the flushing tube 500 and the inflation tube 400 located outside the drainage tube 100 are closed and are provided with injection ports. The injection ports can be connected to a syringe, which can be used to inflate or deflate the airbag 110 or inject water into the intestine. Furthermore, rubber stoppers can be fixedly provided at the ends of the flushing tube 500 and the inflation tube 400, with the injection port located at the rubber stopper. The injection port is sealed under the contraction of the rubber stopper. An openable sealing cap can also be provided at the injection port, which can be operated to open or close the injection port.

[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, and the other end is connected to the flushing tube 500.

[0053] In a further embodiment, refer to Figure 1 The drainage bag 200 is provided with an external threaded interface 210, and the collection end of the drainage tube 100 is provided with an internal threaded interface 120. The internal threaded interface 120 and the external threaded interface 210 are threaded together to realize the connection between the drainage bag 200 and the drainage tube 100.

[0054] Based on the above embodiments, the usage principle and working process of the present invention are as follows:

[0055] Initially, the airbag 110 is in a contracted state. During use, firstly, the insertion end of the drainage tube 100 is inserted into the intestine through the anus. After insertion, air is inflated into the airbag 110 through the inflation tube 400. During inflation, the rotating rod 331 is rotated, causing the rotating block 330 to rotate. The rotating block 330 continuously compresses the flexible tube 320, causing it to deform and providing a moving deformation wave for the flexible tube 320. During this moving deformation wave, the flexible tube 320 continuously interacts with the internal gear 310. During engagement, as the flexible tube 320 forms a moving deformation wave, the compression tube 322 pushes the airbag 110, causing the airbag 110 to continuously adjust its posture. If the airbag 110 is not parallel to the intestinal cross-section at this time, under the pushing of the compression tube 322, the airbag 110 continuously rotates towards a direction parallel to the intestinal cross-section, and is gradually straightened. Furthermore, during the process of the flexible tube 320 forming the moving deformation wave, the compression point of the flexible tube 320 on the intestinal wall continuously changes, eliminating the intestinal folds caused by the device insertion. After the airbag 110 is fully inflated and expanded, the rotating rod 331 can be continuously rotated to fine-tune the posture of the airbag 110, completing the basic fixation of the intestine. Afterwards, the rotating rod 331 can be removed, and the hole on the drainage tube 100 used to install the rotating rod 331 can be sealed with a sealing plug, allowing the device to be used normally. During use, water is injected into the intestine through the flushing tube 500, facilitating the smooth discharge of excrement through the drainage tube 100 into the drainage bag 200. Once a certain amount of excrement has accumulated in the drainage bag 200, a new drainage bag 200 can be replaced. When it is necessary to remove the invention from the patient, air is drawn out through the inflation tube 400, causing the air bag 110 to contract, 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 principles of the present invention should be included within the protection scope of the present invention.
