Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to an internal anal plug anti-leakage structure. Background Technology

[0002] In clinical practice, patients with fecal incontinence, especially those with loose sphincter muscles, cannot control their bowel movements and will excrete feces at irregular intervals, which brings great inconvenience and distress to their lives.

[0003] Currently, the common clinical practice for fecal incontinence patients is to insert tampons into the anus to control the leakage of fecal matter from the rectum. While this method meets certain needs, it has the following problems in its use:

[0004] 1. Traditional tampons are not easy to insert into a patient's anus because of their soft material.

[0005] 2. For patients with fecal incontinence due to sphincter relaxation, traditional tampons are generally too small. After absorbing fecal fluid, they easily slip out of the anus along with the patient's stool, failing to provide anal insertion. This leads to fecal fluid leakage from the anus, macerating the perianal skin and causing incontinence dermatitis. In addition, existing tampons are commonly removed from the anus by pulling out a tampon thread. However, when pulling the tampon out of the anus, the thread is prone to breaking, making the tampon difficult to remove and failing to meet practical application needs.

[0006] How to solve the above problems has become an urgent technical challenge. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide an internal anal plug anti-leakage structure that is easy to operate, insert into and remove from the anus, and is secure and reliable, so as not to cause fecal leakage and skin maceration that could lead to incontinence dermatitis.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An internal anal plug anti-leakage structure includes a rigid tube with an interface thread at one end; a rounded hemispherical object is fitted on the end of the rigid tube away from the interface thread to guide the rigid tube into the patient's anus; an anal plug absorbent is fitted on the rigid tube to perform anal plugging and temporarily absorb fecal matter, and the anal plug absorbent is easy to pull out safely; and a water bladder restrictor is connected to the interface thread to perform secondary anal plugging to prevent fecal matter leakage from macerating the skin and causing incontinence dermatitis, and the water bladder restrictor is easy to pull out safely through its exposed end.

[0010] Preferably, the anal plug absorbent includes a defining collar fitted onto the rigid tube, and a groove longitudinally formed on the threaded sidewall of the interface. It also includes an absorbent core that is covered and wrapped around the defining collar by a yarn mesh at the top and bottom for inserting into the anus and temporarily absorbing fecal matter. The yarn mesh at the top of the absorbent core extends into the cavity of the defining collar from the top and extends out from the bottom, intertwining with the yarn mesh at the bottom of the absorbent core to form a yarn rope. The yarn rope extends out from the groove and is securely adhered to the patient's skin by an adhesive tape.

[0011] Preferably, the water bladder restrictor includes a water bladder body that is detachably and sealingly connected to the interface via a threaded cylinder. The water bladder body is provided with a water supply and drainage component that is connected to an external water supply device for filling the water bladder body with liquid so that it expands and extends outward to seal against the inner wall of the patient's anal cavity to achieve secondary anal plugging.

[0012] Preferably, the water supply and drainage assembly includes a connector provided on the outer wall of the water bladder body, and a water injection pipe is provided on the connector. The end of the water injection pipe away from the connector is connected to an external water supply device through a shut-off valve to realize the water supply and drainage operation of the water bladder body.

[0013] Preferably, the water bladder body is made of TPU thermoplastic polyurethane elastomer material.

[0014] Preferably, the rounded hemisphere and the rigid tube are fixedly connected by a clip-on fastener.

[0015] Preferably, the rounded hemisphere is made of soft silicone material.

[0016] Due to the adoption of the above structure, the beneficial effects of this utility model are as follows:

[0017] In this invention, when clinical care is needed for patients with fecal incontinence, the rectal plug absorbent is fitted onto the outer wall of a rigid tube. The water-filled bladder retainer is then threaded onto the interface to connect the retainer to the rigid tube. The water-filled bladder retainer and the rounded hemisphere securely hold the absorbent in place on the rigid tube. Following this, the rounded hemisphere and the rigid tube guide the medical staff to easily insert the absorbent and water-filled bladder retainer together into the patient's anus at a predetermined position. At this point, the corresponding exposed portions of both the absorbent and the water-filled bladder retainer protrude outside the anus. The inserted portion of the absorbent allows for rectal insertion and temporary absorption of fecal matter. Furthermore, as needed, a predetermined amount of water can be injected into the inserted portion of the water-filled bladder retainer using an external water-injection device. The corresponding part of the water-filled bladder restrictor expands and extends, tightly connecting with the inner wall of the patient's anal cavity. This not only restricts its position but also serves as a secondary closure of the anal cavity. Therefore, the dual closure effect of the clogging device and the water-filled bladder restrictor ensures a stable and reliable closure, effectively improving the closure effect and preventing fecal leakage that could macerate the patient's perianal skin, thus avoiding incontinence dermatitis. Furthermore, when clogging is no longer necessary, the exposed parts of the clogging device and water-filled bladder restrictor allow medical personnel to easily pull them out of the patient's anus, along with the rounded hemisphere and rigid tube, effectively improving ease of use. Therefore, this invention has the advantages of easy insertion and removal from the anus, and a stable and reliable closure that prevents fecal leakage and skin maceration that could cause incontinence dermatitis.

[0023] 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.

[0024] Please see Figures 1 to 2As shown, this utility model provides a built-in anal plug anti-leakage structure, including a rigid tube 2 with an interface thread 1 at one end; a rounded hemispherical body 3 is sleeved on the rigid tube 2 at the end away from the interface thread 1 to guide the rigid tube 2 to be easily inserted into the patient's anus; an anal plug absorbent 4 is also sleeved on the rigid tube 2 for inserting the anus into the patient's anus and temporarily absorbing fecal matter, and the anal plug absorbent 4 is easy to pull out safely; it also includes a water bladder restrictor 5 connected to the interface thread 1 for secondary anal plugging of the patient's anus to prevent fecal matter from leaking out and macerating the skin, causing incontinence dermatitis, and the water bladder restrictor 5 is easy to pull out safely through its exposed end. During use, when clinical care is needed for patients with fecal incontinence, the rectal absorbent 4 is fitted onto the outer wall of the rigid tube 2. The water-filled bladder retainer 5 is then connected to the interface thread 1 to connect the water-filled bladder retainer 5 to the rigid tube 2. The water-filled bladder retainer 5 and the rounded hemisphere 3 work together to securely fix the rectal absorbent 4 to the rigid tube 2. Then, using the guiding effect of the rounded hemisphere 3 and the rigid tube 2, medical staff can easily insert the rectal absorbent 4 and the water-filled bladder retainer 5 into the predetermined position inside the patient's anus. At this time, the exposed parts of both the rectal absorbent 4 and the water-filled bladder retainer 5 extend outside the patient's anus. The inserted portion of the rectal absorbent 4 allows for rectal insertion and temporary absorption of fecal matter. Additionally, external water injection devices can be connected to the corresponding water-filled bladder retainer 5 as needed. The device is partially connected, and a predetermined amount of water is injected into the anal portion of the water-filled bladder restrictor 5 through an external water injection device. This causes the corresponding part of the water-filled bladder restrictor 5 to expand and extend, tightly connecting with the inner wall of the patient's anal cavity. This not only restricts the position but also serves as a secondary anal plug to seal the patient's anal cavity. Therefore, the dual anal plugging and sealing effect of the anal plug absorbent 4 and the water-filled bladder restrictor 5 ensures a stable and reliable anal plugging, effectively improving the anal plugging effect. It can prevent fecal leakage and maceration of the patient's perianal skin, avoiding incontinence dermatitis. Furthermore, when the anal plugging is no longer needed, the exposed parts of the anal plug absorbent 4 and the water-filled bladder restrictor 5 can be easily pulled out by medical staff along with the rounded hemisphere 3 and the rigid tube 2 from the patient's anus, effectively improving the convenience of use.

[0025] In this embodiment, the anal plug absorbent 4 includes a limiting collar 41 sleeved on the rigid tube 2, and a groove 46 longitudinally formed on the side wall of the interface thread 1. It also includes an absorbent cotton core 43 that is covered and wrapped around the limiting collar 41 by a yarn mesh 42 at the top and bottom to provide anal plugging and temporary absorption of fecal matter for the patient. The yarn mesh 42 located at the top of the absorbent cotton core 43 extends into the cavity of the limiting collar 41 from the top and extends out from the bottom, intertwining with the yarn mesh 42 located at the bottom of the absorbent cotton core 43 to form a yarn rope 44. The yarn rope 44 extends out from the groove 46 and is securely attached to the patient's skin by an adhesive tape 45.In clinical practice, when nursing patients with fecal incontinence, a cylindrical anal plug structure is formed by wrapping the top and bottom of the absorbent cotton core 43 with a yarn mesh 42 and then looping it around the limiting ring 41. The yarn mesh 42, located at the top of the absorbent cotton core 43, extends from the top of the limiting ring 41 into its cavity and extends from the bottom, intertwining with the yarn mesh 42 at the bottom of the absorbent cotton core 43 to form a yarn rope 44. The limiting ring 41, together with the absorbent cotton core 43 and the yarn mesh 42, is then fitted onto the outer wall of the rigid tube 2. Finally, the water-filled bladder limiter 5 is connected to the interface thread 1 to secure the water-filled bladder limiter. 5 is connected to the rigid tube 2, thereby using the mutual clamping action of the water-filled retainer 5 and the rounded hemisphere 3 to firmly fix the anal absorbent 4 onto the rigid tube 2. At the same time, the yarn rope 44 extends out of the groove 46 from the outside of the rigid tube 2, and the sealing effect of the yarn rope 44 can seal the groove 46. Under the guidance of the rounded hemisphere 3 and the rigid tube 2, medical staff can easily insert the limiting ring 41 together with the absorbent cotton core 43, the yarn net 42, and the insertion part of the water-filled retainer 5 into the predetermined position in the patient's anus. At this time, the yarn rope 44 extends out of the patient's anus and is fixed by the adhesive tape 45. The water-filled balloon retainer 5 is placed on the skin at the corresponding location on the patient's anus, with the exposed portion extending outside the anus. This allows the absorbent cotton core 43 to plug the anus and temporarily absorb stool. The absorbent cotton core 43 is also shaped and secured by a yarn mesh 42, ensuring it fits firmly within the retaining ring 41 and preventing it from unraveling and falling off, thus maintaining the plugging effect. Furthermore, an external water injection device can be connected to the corresponding portion of the water-filled balloon retainer 5 as needed. This allows a predetermined amount of water to be injected into the inserted portion of the water-filled balloon retainer 5, causing it to expand and extend into the patient's anal cavity. The inner walls of the anal canal are tightly connected, which not only limits the position but also serves as a secondary anal plug to seal the patient's anal cavity. Therefore, the dual anal plugging and sealing effect of the anal plug absorbent 4 and the water-filled bladder restrictor 5 ensures a stable and reliable anal plugging, effectively improving the anal plugging effect. It can prevent fecal leakage and maceration of the patient's perianal skin, avoiding incontinence dermatitis. Furthermore, when the anal plug is no longer needed, the exposed parts of the gauze rope 44 and the water-filled bladder restrictor 5 can be easily pulled by medical staff to remove the anal plug absorbent 4 and the water-filled bladder restrictor 5, along with the rounded hemisphere 3 and the rigid tube 2, from the patient's anus, effectively improving the convenience of use.

[0026] In this embodiment, the water bladder limiter 5 includes a water bladder body 52 that is detachably and sealingly connected to the interface thread 1 via a threaded cylinder 51. A water supply and drainage assembly 53 is provided on the water bladder body 52, which is connected to an external water supply device for injecting water into the water bladder body 52 to expand and seal against the inner wall of the patient's anal cavity, thus achieving secondary anal insertion. The water supply and drainage assembly 53 includes a connector 100 located on the outer wall of the water bladder body 52. ​​A water injection pipe 200 is provided on the connector 100, and the end of the water injection pipe 200 away from the connector 100 is connected to the external water supply device via a shut-off valve 300 to realize the supply and drainage operations of the water bladder body 52. During use, after the rectal absorbent 4 is fitted onto the outer wall of the rigid tube 2, the water bag body 52 is connected to the rigid tube 2 via the threaded sleeve 51 of the water bag retainer 5 using the threaded interface 1. At this time, the threaded sleeve 51 restricts the corresponding part of the yarn rope 44 onto the groove 46. The threaded sleeve 51, the water bag body 52, and the rounded hemisphere 3 work together to securely fix the rectal absorbent 4 onto the rigid tube 2. Guided by the rounded hemisphere 3 and the rigid tube 2, medical personnel can easily insert the retaining ring 41, along with the absorbent core 43, the yarn mesh 42, the threaded sleeve 51 of the water bag retainer 5, and the connector 100 of the water bag body 52 and the water delivery / drainage assembly 53, into the predetermined position inside the patient's anus. At this time, the... The water pipe 200 and the shut-off valve 300 extend outside the patient's anus. The shut-off valve 300 of the water supply and drainage assembly 53 is then connected to an external water injection device. As needed, the shut-off valve 300 is opened and the external water injection device is activated to inject a predetermined amount of water into the cavity of the water bladder body 52 through the shut-off valve 300, the water injection pipe 200, and the connector 100. This causes the water bladder body 52 to expand and extend, and to connect tightly with the inner wall of the patient's anal cavity. Thus, the water bladder body 52 further securely fixes the water bladder retainer 5 and the anal plug absorbent 4 in a predetermined position inside the patient's anus, while also serving as a secondary anal plug to seal the patient's anal cavity. This prevents fecal leakage from soaking the patient's perianal skin and causing incontinence dermatitis, effectively improving the safety of use. When it is necessary to remove the water-filled bladder restrictor 5, the yarn rope 44 and the water injection tube 200 are used to facilitate the pulling of medical staff to remove the anal plug absorbent 4 and the water-filled bladder restrictor 5 together with the rounded hemisphere 3 and the rigid tube 2 from the patient's anus, which effectively improves the convenience of use.

[0027] In this embodiment, the water bladder body 52 is made of TPU thermoplastic polyurethane elastomer material.

[0028] In this embodiment, the rounded hemisphere 3 and the rigid tube 2 are fixedly connected by a clip-on connection. The rounded hemisphere 3 is made of soft silicone material.

[0029] In specific use of this embodiment, firstly, when clinical care is needed for patients with fecal incontinence, the top and bottom of the absorbent cotton core 43 are covered with a yarn mesh 42 and then wrapped around the limiting ring 41 to form a cylindrical anal plug structure. Next, the yarn mesh 42 at the top of the absorbent cotton core 43 extends into the cavity of the limiting ring 41 from the top and extends out from the bottom, intertwining with the yarn mesh 42 at the bottom of the absorbent cotton core 43 to form a yarn rope 44. Then, the limiting ring 41, together with the absorbent cotton core 43 and the yarn mesh 42, is fitted onto the outer wall of the rigid tube 2. Secondly, the water bag body 52 is connected to the rigid tube 2 via the threaded sleeve 51 of the water bag limiter 5 using the threaded interface thread 1. Together, at this time, the threaded cylinder 51 restricts the corresponding part of the yarn rope 44 onto the groove 46, thereby using the mutual clamping action of the threaded cylinder 51, the water bag body 52, and the rounded hemisphere 3 to firmly restrict the anal absorbent 4 onto the rigid tube 2. At the same time, the yarn rope 44 extends out of the outside of the rigid tube 2 from the groove 46, and the sealing action of the yarn rope 44 can seal the groove 46. Then, under the guidance of the rounded hemisphere 3 and the rigid tube 2, medical staff can easily insert the restricting collar 41 together with the absorbent cotton core 43, the yarn net 42, the threaded cylinder 51 of the water bag restrictor 5, and the connector 100 of the water bag body 52 and the water delivery and drainage assembly 53 into the predetermined position in the patient's anus. At this time, the yarn rope 44 extends out of the patient's anus and is fixed to the corresponding skin area of ​​the patient by adhesive tape 45. The water injection pipe 200 and the shut-off valve 300 extend out of the patient's anus. Thus, the absorbent cotton core 43 is used to plug the patient's anus and temporarily absorb the stool. In addition, the absorbent cotton core 43 is wrapped and shaped by the yarn mesh 42 to securely fit the limiting collar 41, which can prevent the absorbent cotton core 43 from falling off and affecting the plugging effect. Finally, as needed, the shut-off valve 300 of the water supply and drainage assembly 53 is connected to the external water injection device. As needed, the shut-off valve 300 is opened and the external water injection device is started to inject a predetermined amount of water through the shut-off valve 300, the water injection pipe 200, and the connector 100 to the anus. Within the cavity of the water-filled bladder body 52, the water-filled bladder body 52 expands and extends, tightly connecting with the inner wall of the patient's anal cavity. This not only limits its position but also serves as a secondary anal plug to seal the patient's anal cavity. Therefore, the dual anal plugging and sealing effect of the anal plug absorbent 4 and the water-filled bladder restrictor 5 ensures a stable and reliable anal plugging, effectively improving the anal plugging effect. It can prevent fecal leakage from soaking the patient's perianal skin and avoid causing incontinence dermatitis. Furthermore, when the anal plugging is no longer needed, the gauze rope 44 and the water injection tube 200 allow medical staff to easily pull and remove the anal plug absorbent 4 and the water-filled bladder restrictor 5, along with the rounded hemisphere 3 and the rigid tube 2, from the patient's anus, effectively improving the ease of use.

[0030] In summary, the present invention adopts the above-described structure, which has the advantages of being easy to insert into and remove from the anus, and being a stable and reliable plug that is less likely to cause fecal leakage and skin maceration, resulting in incontinence dermatitis.
