Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a nursing device for severely incontinent patients. Background Technology

[0002] Fecal incontinence refers to the involuntary leakage of feces and gas from the anus, a symptom of bowel dysfunction. While not very common, fecal incontinence is not life-threatening. It causes physical and psychological distress, severely interfering with normal life and work.

[0003] Fecal incontinence can easily lead to various complications, the most common being skin inflammation of the perineum and sacrococcygeal region, and pressure ulcers (pressure sores). Fecal incontinence is more prevalent in the elderly, critically ill patients, and bedridden paralyzed patients. Due to the irritation from feces, the perineal skin is constantly in a moist and erosive state from metabolic products, making it prone to redness, swelling, ulceration, and skin breakdown. Infection can penetrate deep into the muscle layer or extend to the scrotum, labia, and groin; it can also contaminate the urethral and vaginal openings, causing retrograde infection, which not only exacerbates the patient's suffering but also complicates clinical nursing care. Because the perineum is frequently irritated by fecal matter, the perianal skin can develop erosion, itching, ulcers, and pain. Some patients restrict their diet and water intake to reduce bowel movements, leading to weight loss, which is also detrimental to their health.

[0004] For patients with severe incontinence, ostomy bags are currently commonly used for perianal skin protection. However, this method is relatively expensive; moreover, for some patients with thin skin, the adhesive of the ostomy bag can easily cause skin lacerations during changes, potentially damaging the perianal skin. In practice, anal tube devices can also be used for patients with severe incontinence, but in actual use, patients' stools can be either dry or loose, and existing anal tubes designed to drain stool often cause poor drainage, leading to anal tube blockage. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a nursing device for critically incontinent patients that features multiple sealing and leak-proof functions, is suitable for patients with thin skin, and effectively prevents skin maceration.

[0006] The technical objective of this utility model is achieved through the following technical solution: A nursing device for severely incontinent patients includes a hollow anal tube made of a soft material; the anal tube includes an insertion section inserted into the anus and an external retention section located outside the anus; a collection device is connected to the opening of the external retention section; an air bladder is arranged around the outer side of the insertion section away from the external retention section; a detachably connected tampon is arranged around the outer side of the insertion section near the external retention section; an inlet tube communicating with the anal tube is provided on the external retention section, the inlet tube being connected to an infusion set; a squeezing device is sleeved on the outer side of the external retention section between the inlet tube and the opening of the external retention section.

[0007] Preferably, the airbag is also connected to an inflation tube; the end of the inflation tube away from the airbag is provided with a connector; the connector is provided with an air inlet plug.

[0008] Preferably, the infusion set includes a syringe.

[0009] Preferably, the insertion section has two drainage holes that are opposite to each other and spaced apart near the opening of the insertion section.

[0010] Preferably, the collection device includes a drainage bag; the drainage bag is connected to the outer section through a drainage tube; one end of the drainage tube is sleeved on the opening of the outer section, and the other end is provided with a check valve and placed inside the drainage bag.

[0011] Preferably, the upper end of the drainage bag is provided with an exhaust pipe.

[0012] Preferably, the lower end of the drainage bag is provided with a drain pipe; the drain pipe is provided with a valve switch.

[0013] Preferably, the insertion section has an annular groove on the outer side near the outer section; the cotton strip has an adhesive layer that mates with the annular groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This novel anal tube is made of soft materials such as silicone and PVC. The soft material reduces friction and damage to the anus and perianal skin, making it especially suitable for severely ill patients with thin skin. The insertion section of the anal tube is equipped with an airbag and tampons; the airbag acts as the first line of defense, fitting tightly against the anal wall after inflation to prevent fluid leakage; the removable tampons act as the second line of defense, absorbing residual exudate and preventing skin maceration; this technology creates a double leak-proof system. The infusion tube can be used to inject liquid to dilute hardened stool via an infusion set, and the external insertion section allows for manual unblocking, solving the problem of easy blockage in traditional anal tubes. The collection device enables directional drainage of stool, avoiding soiling sheets or clothing and reducing the difficulty of care. Using the above-mentioned technical measures, it has the advantages of multiple leak-proof and blockage-proof features, suitability for patients with thin skin, and effective prevention of skin maceration.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0019] like Figure 1 — Figure 3As shown, a nursing device for severely incontinent patients includes a hollow anal tube 1 made of a soft material. The anal tube 1 includes an insertion section 11 inserted into the anus and an external retention section 12 located outside the anus. A collection device is connected to the opening 121 of the external retention section 12. An air bladder 2 is arranged around the outer side of the insertion section 11 away from the external retention section 12. A detachably connected tampon 3 is arranged around the outer side of the insertion section 11 near the external retention section 12. An inlet tube 4 communicating with the anal tube 1 is provided on the external retention section 12, and the inlet tube 4 is connected to an infusion set (not shown in the figure). A squeezing device 6 is fitted on the outer side of the external retention section 12 between the inlet tube 4 and the opening 121. In practice, the anal tube 1 is made of soft materials such as silicone or PVC. Soft materials reduce friction damage to the anus and perianal skin, making it especially suitable for severely incontinent patients with thin skin. Figure 1 As shown, the anal tube 1 has a hollow cylindrical structure with openings at its upper and lower ends, namely the insertion section opening 111 of the insertion section 11 and the external retention section opening 121 of the external retention section 12. The insertion section 11 and the external retention section 12 are separated by the location of the tampon 3 or the annular groove 112. In this embodiment, the lower side of the tampon 3 or the annular groove 112 is the external retention section 12, and the area from the lower side of the tampon 3 or the annular groove 112 to the insertion section opening 111 is the insertion section 11. In actual use, the lower end of the insertion section 11 can be located within a range of 0-2 cm below the tampon 3 or the annular groove 112. An airbag 2 and a tampon 3 are spaced apart on the outside of the insertion section 11 of the anal tube 1. The airbag 2 acts as the first sealing layer, fitting tightly against the anal wall after inflation to prevent fluid leakage. The removable tampon 3 acts as the second sealing layer, absorbing residual exudate and preventing skin maceration. This technical measure forms a double leak-proof system. The outer drainage section 12 is equipped with an inlet tube 4 and a squeezing device 6 spaced vertically. The inlet tube 4 is fixedly installed on the outer drainage section 12, with one end connected to the inside of the anal tube 1 and the other end located outside the anal tube 1. The squeezing device 6 is fitted onto the outside of the outer drainage section 12, allowing it to move up and down on the outside of the outer drainage section 12, thus allowing it to be positioned closer to or further away from the inlet tube 4. The inlet tube 4 can be used to inject liquid through an infusion set to dilute hardened feces, and the squeezing device 6 can be used for manual unblocking, solving the problem of easy blockage in traditional anal tubes 1. The collection device enables directional drainage of feces, avoiding soiling bed sheets or clothing and reducing the difficulty of nursing care. The above technical measures have the advantages of multiple sealing to prevent leakage and blockage, suitability for patients with thin skin, and effective prevention of skin maceration.

[0020] like Figure 1 , Figure 2As shown, the airbag 2 is also connected to an inflation tube 21; the end of the inflation tube 21 away from the airbag 2 is provided with a connector 22; the connector 22 is provided with an air inlet plug 23. In practice, the inflation tube 21 allows medical staff to control the pressure of the airbag 2 through an external air pump or syringe to avoid over-inflation that could cause patient discomfort; the air inlet plug 23 ensures that the airbag 2 maintains a sealed state for a long time to prevent air leakage and failure.

[0021] Infusion sets include syringes. In practice, the infusion set (not shown in the diagram) uses syringes to precisely adjust the amount of flushing fluid (such as normal saline or warm water), allowing for flexible operation based on the consistency of the stool and avoiding excessive flushing that could cause intestinal irritation. Ordinary syringes are inexpensive, reducing the overall cost of nursing supplies.

[0022] like Figure 1 , Figure 2 As shown, the insertion segment 11 has two drainage holes 13 positioned opposite each other and spaced apart near the insertion segment opening 111. In a specific implementation, the drainage holes 13 include a first drainage hole 131 and a second drainage hole 132 positioned opposite each other and spaced apart near the insertion segment opening 111. The dual drainage hole design expands the drainage area, so even if one hole is blocked by dry stool, the other side can still maintain drainage function; the symmetrical distribution of the holes avoids poor drainage caused by unilateral pressure deformation of the anal tube 1.

[0023] The collection device includes a drainage bag 5; the drainage bag 5 is connected to the external drainage section 12 via a drainage tube 7; one end of the drainage tube 7 is fitted onto the opening 121 of the external drainage section 12, and the other end is equipped with a check valve 71 and is located inside the drainage bag 5. In practice, the drainage bag 5 is usually made of transparent material, and graduations are provided on the bag body. By setting the check valve 71, liquid and gas in the drainage bag 5 are prevented from flowing back into the anal tube 1, thus avoiding contamination of the patient's intestines or causing infection; the transparent material of the drainage bag 5 facilitates observation of stool characteristics and measurement of drainage volume, aiding in medical judgment.

[0024] The upper end of the drainage bag 5 is equipped with an exhaust pipe 51. In practice, a filter or valve (not shown in the figure) can be connected to the exhaust pipe 51 to reduce the pollution of the environment by the odor of excrement. By setting the exhaust pipe 51 to release the gas accumulated in the bag, it prevents the drainage bag 5 from expanding or the pressure from increasing due to gas accumulation, which would affect the drainage efficiency.

[0025] The lower end of the drainage bag 5 is equipped with a drain pipe 52; the drain pipe 52 is equipped with a valve switch 53. In practice, by setting the valve switch 53, the drain pipe 52 can be closed at any time, so that the amount of feces in the drainage bag 5 can be discharged in a unified manner after accumulating to a certain scale, ensuring the accuracy of measurement; at the same time, it avoids frequent discharge, which would increase the workload of nursing.

[0026] The insertion section 11 has an annular groove 112 on the outer side near the outer section 12; the tampon 3 has an adhesive layer 31 that mates with the annular groove 112. In practice, the thickness of the tampon 3 can be selected according to actual needs, and a removable tampon 3 can be used for a wider range of applications.

[0027] The annular groove 112 provides a fixing point for the tampon 3, preventing the tampon 3 from shifting and causing blockage failure; at the same time, it avoids direct contact between the traditional ostomy bag adhesive and the skin, reducing the risk of tearing injury. The adhesive layer 31 (such as medical adhesive tape) allows for quick installation and removal of the tampon 3, and the tampon 3 can be replaced separately after contamination, without the need to replace the entire anal tube 1, thus reducing costs.

[0028] The outer section 12 is fitted with a squeezing device 6 on its outer side near the liquid inlet pipe 4 and the outer section opening 121. In practice, when stool drainage is obstructed, liquid enters through the liquid inlet pipe 4, and the squeezing device 6 simultaneously flushes and squeezes to facilitate stool drainage. The squeezing device 6 employs existing technology, such as a drainage tube squeezing device with patent number CN201922459724.3, a drainage tube squeezing device with patent number CN202221668696.1, or a body cavity drainage tube squeezing device with patent number CN202020236390.3.

[0029] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
