Description

Technical Field

[0001] The utility model relates to a device applicable to enemas and prevention of perianal incontinence dermatitis. Background Art

[0002] Incontinence dermatitis (IAD), also known as incontinence-associated dermatitis, is a skin inflammation caused by long-term exposure of the skin to urine and / or feces. It is the most common complication among critically ill patients, especially those with fecal and urinary incontinence. The occurrence of IAD greatly increases the pain of patients and affects their quality of daily life.

[0003] In different nursing units, the prevalence and incidence of IAD vary. Foreign studies have shown that: due to the complex condition of ICU patients, most of them have phenomena such as abnormal intestinal function, dysbacteriosis, and anal sphincter relaxation. Coupled with the use of anti-infection treatment and enteral nutrition, the prevalence of IAD in critically ill patients is as high as 36.0% - 50%. Domestic studies have shown that the probability of fecal incontinence in inpatients is 17.6%, and about 42.5% of patients with fecal incontinence will have varying degrees of skin damage such as skin redness and blisters, that is, incontinence dermatitis (Incontinence-associated dermatitis, IAD).

[0004] The occurrence of IAD is related to the type and frequency of incontinence, and also related to the patient's own skin and nutritional status, medications, and their own activity. The Perineal assessment tool (PAT) is currently recognized as a tool for assessing the risk of IAD. This assessment tool mainly assesses the risk of IAD in patients from four aspects: the type and intensity of stimulation (formed feces, liquid feces, etc.), the time of skin exposure to stimulation, the perineal skin condition, and related factors increasing the risk of diarrhea (such as hypoproteinemia, use of antibiotics, nasogastric feeding, etc.). Each aspect is evaluated using the Likert 3-level scale, with a total score of 4 - 12 points. The higher the score, the greater the risk of IAD. A score of 7 - 12 points belongs to high risk, and a score of 4 - 6 points belongs to low risk. Xie Chunxiao et al. conducted a Chinese version reliability and validity test on this assessment tool. The Cronbach ， sa coefficient was 0.512, the test-retest reliability was 0.791, the content validity of PAT was 0.95, and the cumulative variance contribution rate was 67.397%, showing good sensitivity and specificity.

[0005] IAD not only increases the length of hospital stay of patients, but also is not conducive to the treatment prognosis. The prevention of IAD is even more important, and good and effective prevention methods can relieve the pain of patients. The treatment of simple urinary incontinence is relatively easy, while the treatment of fecal incontinence or double incontinence is difficult. Considering the characteristics of critically ill patients, more than 95% of the patients need indwelling catheters due to the need for condition observation and treatment, and there are relatively few patients with urinary incontinence.

[0006] Related studies have shown that an anal ostomy bag can collect and hold feces, reducing the spread range of feces. The bottom plate material of it is mainly a hydrocolloid skin protectant, which can promote the healing of dermatitis, erosion and ulcers. However, the amount of feces collected is limited and it is prone to leakage. For the fecal drainage by tracheal intubation, a tracheal intubation needs to be inserted into the patient's anus, and it can continuously drain after connecting to a disposable negative pressure drainage device. However, it will damage the anal canal mucosa, and the catheter is prone to blockage, with a relatively high nursing cost. At the same time, it is not conducive to the patient's turning over, which will reduce the comfort level. Once IAD occurs in ICU patients, it will affect the quality of life of the patients and increase the workload of nursing staff. Summary of the Invention

[0007] The purpose of the present utility model is to provide a device applicable to enema and prevention of perianal incontinence dermatitis, which helps to prevent incontinence dermatitis caused by feces in patients and is applicable to enema.

[0008] The technical solution of the present utility model lies in: a device applicable to enema and prevention of perianal incontinence dermatitis, including a collection bag. An opening is provided at the bottom of the collection bag, and a paste leak-proof structure is provided on the bottom surface of the collection bag and located outside the opening. An annular drainage tube is fixed in the collection bag and located outside the opening. The annular drainage tube has an extension tube part passing through the side part of the collection bag, and side holes are spaced on the annular drainage tube. A drawstring is provided at the top surface of the collection bag and a tie is installed.

[0009] Further, the end of the extension tube part is connected with a three-way tube. One port of the three-way tube is connected with a physiological saline bag through an infusion set, and the other port of the three-way tube is connected with a collection bottle through a drainage tube, and the collection bottle is connected with a negative pressure drainage device.

[0010] Further, the three-way tube is a Y-shaped variable-diameter tree branch three-way tube. The thick port of the Y-shaped variable-diameter tree branch three-way tube is connected with the collection bottle through a drainage tube, and the thin port of the Y-shaped variable-diameter tree branch three-way tube is connected with the infusion set.

[0011] Further, a Robert clamp is provided on the drainage tube.

[0012] Further, the paste leak-proof structure includes a circle of adhesive layer provided on the bottom surface of the collection bag and located outside the opening, and lower convex parts are respectively provided in the middle of the front side and the middle of the rear side of the adhesive layer.

[0013] Further, the lower convex part is made of a stoma leakage-proof paste.

[0014] Further, a fan-shaped notch is provided in the middle of the front side of the outer ring of the adhesive layer.

[0015] Further, the opening is oval.

[0016] Further, the annular drainage tube is a silicone hose, and the side holes are oval holes.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] 1. This device helps prevent fecal incontinence dermatitis in patients.

[0019] 2. The opening of this device is cut into an oval shape according to the shape of the anus, and fan-shaped cuts are made at the 6 o'clock and 12 o'clock directions on both sides. The edge of the oval cut is coated with a stoma leakage-proof paste, which can make the stoma chassis stick more flatly, tightly and without tension.

[0020] 3. A silicone annular drainage tube with multiple side holes is placed in the collection bag and connected to a negative pressure drainage device through a three-way tube. By using continuous low negative pressure, the annular drainage tube is firmly adsorbed on the bottom surface of the collection bag, which can increase the adsorption force between the bottom surface of the collection bag and the perianal skin, and at the same time increase the suction area of the annular drainage tube, reduce tube blockage, and prevent leakage of the anal bag.

[0021] 4. A Robert clip is adopted, which is convenient to control the central negative pressure at any time, and the collection bag can be flushed at any time through the connection of normal saline. The annular drainage tube can be flushed while opening the Robert clip to keep the annular drainage tube unobstructed and ensure the cleanliness of the entire drainage device.

[0022] 5. Through the drawstring design with a tie, it is convenient to shape the collection bag during the pasting process. During the patient's defecation interval, the perianal area can be cleaned through the drawstring to keep the perianal area dry and clean. For patients who need enema due to intestinal obstruction, enema can be performed through the drawstring, realizing the integration of enema and negative pressure drainage device, reducing the workload of nurses.

[0023] 6. This device can assist nurses in screening high-risk patients with IAD and give positive and effective predictive nursing, which is expected to reduce the incidence rate of IAD and the severity of IAD. This device has three functions of collection, flushing and suction, and can play a better isolation and protection role. The collection bag can collect feces, avoid feces contacting the perianal skin, and prevent the skin from being macerated and irritated. For patients with damaged perianal skin, hydrocolloid dressings can be pasted on both sides of the buttocks first and then the anal bag can be pasted to prevent skin damage when tearing off the anal bag. Secondly, the flushing function can solve the problem of fecal residue in the anal bag, reduce bacteria in the bag, and keep it clean.

[0024] 7. If the device is not contaminated and there is no leakage, its service life can be extended. The cleaning device can be retained for 2 - 3 days, which can also reduce the workload of nursing staff. In addition, low negative pressure suction is a non-invasive operation. Nurses can adjust the negative pressure in a timely manner according to the characteristics of feces to remove feces. Moreover, the negative pressure suction does not directly contact the intestinal mucosa and perianal skin, so it will not cause local skin damage, and the patient has good comfort. It also helps to solve a major problem in the treatment of feces of ICU patients in prone position ventilation. Brief Description of the Drawings
