Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary appliances, in particular to a fecal incontinence management device combining an improved ostomy bag with low negative pressure drainage. Background Art

[0002] Incontinence dermatitis is skin damage caused by skin exposure to feces or urine. Incontinence is the main cause of incontinence dermatitis. For patients with fecal incontinence, it is advisable to use collection and / or drainage devices to manage feces, and remove the collection and / or drainage devices when defecation can be controlled. Currently, ostomy bags are used clinically to collect pasty or watery stools.

[0003] Publication number "CN220558164U" provides a stool collection device for incontinence dermatitis. It can promote the healing of perianal incontinence dermatitis in patients through hydrocolloid dressings. The locking nut and the annular gasket are arranged to prevent the negative pressure tube from being easily detached after being connected to the connecting tube. When it is necessary to flush the ostomy bag body, it is only necessary to close the valve and connect the syringe to the injection tube to flush the ostomy bag. Flushing can prevent the perianal skin from being contaminated and reduce the occurrence of incontinence dermatitis.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Firstly, during actual use, the ostomy bag body in the stool collection device does not fit tightly around the anus, and the patient's comfort is poor and the feces are easily affected by the body position, which leads to feces overflow. The prevention of incontinence dermatitis has little benefit to the patients. Secondly, although the negative pressure bottle in the stool collection device can generate negative pressure to attract the excrement inside the ostomy bag body into the bottle, once the negative pressure inside the negative pressure bottle is consumed and the valve is not closed, the excrement inside the negative pressure bottle can easily flow back through the negative pressure tube and the connecting tube to the ostomy bag body, causing secondary pollution, and the practicality is poor.

The inlet tube head 201 facilitates the connection of the negative pressure drainage airbag 202 with the drainage tube 301.

[0039] An inner liner 207 is fixedly connected to the upper side of the inlet tube head 201. The inner liner 207 and the inlet tube head 201 are an integrated structure. The upper end of the inner liner 207 is conical. The inner liner 207 with a conical upper end can concentrate the excrement guided down from the drainage tube 301 into the anti-backflow duckbill valve 206. The lower end of the inner liner 207 is bonded with an anti-backflow duckbill valve 206. The anti-backflow duckbill valve 206 is made of a rubber duckbill valve. The anti-backflow duckbill valve 206 made of a rubber duckbill valve has an anti-backflow capability to prevent the excrement entering the negative pressure drainage airbag 202 from backflowing upward into the drainage tube 301. Due to the detailed internal structure of the anti-backflow duckbill valve 206 The structure and working principle are relatively mature technologies in the prior art, so they will not be elaborated on here. A deflation nozzle 204 is arranged on the left side of the annular side of the negative pressure drainage airbag 202. The deflation nozzle 204 and the negative pressure drainage airbag 202 are an integrated structure. The deflation nozzle 204 is convenient for exhausting the air inside the negative pressure drainage airbag 202. A valve cover 205 is installed on the upper end of the deflation nozzle 204. The valve cover 205 is connected to the deflation nozzle 204 by a threaded connection. The valve cover 205 can block the deflation nozzle 204. A first sealing ring is installed inside the valve cover 205. The first sealing ring makes the sealing between the valve cover 205 and the deflation nozzle 204 better.

[0040] Working principle: When using the device, the patient first holds the guide bucket 303 with his hand and aligns the anus patch 304 to fit around the anus and keeps it still. Then the nursing staff opens the air nozzle cover 205, and at this time, the unused feces storage bag 100 and the negative pressure drainage air bag 202 are squeezed and flattened respectively, and the internal air of the feces storage bag 100 and the negative pressure drainage air bag 202 is completely discharged through the air release nozzle 204. Then, the air nozzle cover 205 is installed on the upper end of the air release nozzle 204 to close the air release nozzle 204. Afterwards, the stool storage bag 100 and the negative pressure drainage airbag 202 can be released, and the negative pressure drainage airbag 202 will gradually expand outward to restore its original shape. During this process, the restored negative pressure drainage airbag 202 will generate a certain adsorption force and suction the drainage tube 301 through the anti-backflow duckbill valve 206, so that the drainage tube 301 suctions the diversion bucket 303, so that the excrement discharged into the diversion bucket 303 accelerates to flow downward. When the nursing staff repeatedly squeezes the negative pressure drainage airbag 202, The negative pressure drainage airbag 202 will repeatedly expand outward to continuously generate suction force to continuously suck the drainage tube 301, so that the excrement in the drainage tube 301 can flow downward more quickly; and the excrement in the drainage tube 301 will pass through the inner liner 207 and the anti-backflow duckbill valve 206 downward into the negative pressure drainage airbag 202, and finally flow downward through the negative pressure drainage airbag 202 into the feces storage bag 100 for temporary storage. In this process, the anti-backflow duckbill valve 206 prevents the excrement from entering the negative pressure drainage airbag 202. The excrement flows upward into the drainage tube 301; at the same time, the heart-shaped anal patch 304 fits the physiological curve around the human anus more closely, preventing the excrement from easily overflowing to the outside of the anal patch 304. When the defecation is completed, only the device needs to be removed and the sealing cover 102 opened to pour out the excrement in the fecal storage bag 100 for cleaning, so that the device can be used repeatedly several times on the same day, and the device can also be used once.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
