Description

ostomy bag

technical field

The invention relates to the technical field of medical consumables, in particular to an ostomy bag.

Background technique

Some bowel and bladder diseases such as intestinal obstruction may endanger the life of the patient if not treated in time. Timely treatment through ostomy can improve the quality of life of the patient. Patients who have undergone ostomy surgery cannot defecate from the anus, but need to attach an ostomy bag to the stoma site to collect the excreted feces of the patient.

Contents of the invention

The ostomy bag does not need to be changed every day. Generally, the ostomy bag is replaced every 4-7 days, and the use time can also be extended according to the shape of the stool. The use time of each ostomy bag is not fixed. Patients can refer to two indicators to evaluate whether to replace the ostomy bag, one is whether there is leakage, and the other is whether the skin around the stoma is normal. Inventor finds in long-term clinical care:

(1) The inner wall of the excrement entrance of the ostomy bag is close to the skin around the patient's stoma, especially when the patient's stool is loose, the inner wall of the ostomy bag is soaked, which increases the patient's discomfort. Increased risk of skin infection and redness around the stoma.

(2) When a new ostomy bag is replaced, there is no stool in the ostomy bag. If the patient only excretes a small amount of loose stool at this time, the loose stool will soak the inner wall of the ostomy bag and stick the inner wall of the ostomy bag together, resulting in The cavity channel in the ostomy bag is not smooth, and when a small amount of loose stool is excreted next time, the stool cannot flow smoothly to the bottom of the ostomy bag due to the loose stool and small amount, so that these few stools are in the upper half of the ostomy bag. Build up, soaking the skin around the stoma. Although dry stool can easily fall to the bottom of the ostomy bag under the action of gravity, and with the accumulation of stool, a channel with little space is opened between the inner walls of the ostomy bag, but for patients who only excrete a small amount of loose stool Ostomy bags are prone to poor stool circulation. When the patient is resting at night, the stoma bag is basically horizontal. If the cavity channel is not smooth at this time, the accumulation of loose stool around the stoma will be exacerbated.

(3) Loose stool has a certain fluidity. After the loose stool accumulates in the stoma bag, if the patient lies down at this time, the stool will flow to the stoma of the patient, causing the skin around the stoma to soak in the stool and cause infection and redness.

(4) For severe patients who can only lie in bed, due to unattended care at night, the mashed stool excreted by the patient cannot be discharged from the ostomy bag in time, which aggravates the above situation.

In order to solve the above-mentioned problems encountered in the use of existing ostomy bags, the present invention provides the following solutions: establish a stool circulation channel inside the ostomy bag to solve (1) and (2) in the above technical problems; Most of the moisture in the stool is discharged in time, reducing the fluidity of thin stools, and solving (3) and (4) in the above-mentioned technical problems.
