Description

Leak protection ostomy bag convenient to change abluent Technical Field The invention relates to an ostomy bag, in particular to a leak-proof ostomy bag convenient to replace and clean, and belongs to the technical field of ostomy bags. Background The ostomy bag is a medical care product specially designed for patients who undergo enterostomy or urostomy, is adhered to the artificial stoma of the abdomen to replace anus or urethra which cannot work normally to collect human excretions, is mainly divided into one piece type and two pieces type and the like, has the core functions of efficiently collecting the excretions to prevent leakage, protecting the skin around the stoma from being stimulated by the excretions, and helping the patients get rid of bedridden infusion after operation and maintain normal life rhythm. In order to avoid the problem of seepage, the two-piece ostomy bag is connected in a hard buckle mode, the sealing effect can be ensured, the replacement operation is inconvenient, in addition, forced pressing or dragging is needed in the replacement process, and secondary damage is easily caused to the ostomy of the patient. The automatic cleaning type ostomy bag device (with the publication number of CN 108685632B) has an automatic cleaning function, can thoroughly clean the ostomy bag, reduces pollution in the ostomy bag, is convenient to use, is safe and reliable, has little local skin irritation and damage, is firm in fixation and accurate in position, reduces the economic burden of a patient, is convenient for the patient to move, and improves the life quality of the patient, but the ostomy bag device is excessively complex in structure, and the use cost of the patient is inevitably increased due to the arrangement of structures such as a water pumping device, a water storage device, a waste liquid treatment device and the like. The patent name is a Chinese patent with a disposable replaceable ostomy bag (publication number is CN 217566518U), solves the problem that the prior ostomy bag is directly replaced, and causes resource waste, so that the replaceable ostomy bag can be repeatedly used, and only the plastic bag is replaced each time, the replacement is simple and convenient, the money is saved, and the resource utilization is improved. However, although the ostomy bag can save the use cost by only replacing the plastic bag, the chassis connection mode is the same as the traditional buckle type ostomy bag, and disturbance to the ostomy position in the replacement process cannot be effectively avoided. Disclosure of Invention In view of the above, the present invention provides a leak-proof ostomy bag that facilitates replacement and cleaning, solves or alleviates the technical problems of the prior art, and at least provides a beneficial choice. The technical scheme of the embodiment of the invention is realized in that the leak-proof ostomy bag convenient to replace and clean comprises a bag body component and a sealing mechanism, wherein the bag body component comprises an outer lining bag, a collecting bag and a ostomy chassis; The collecting bag is fixedly connected to the inner side wall of the outer lining bag and extends to the outside of the outer lining bag, the stoma chassis is arranged on one side of the outer lining bag, the sealing mechanism is adhered to the outer side wall of the collecting bag, a quick-dismantling connecting mechanism is arranged between the stoma chassis and the outer lining bag and is flexible buckle type, rotary clamping type, synchronous locking type or inserting type, and the quick-dismantling connecting mechanism is used for changing the stress direction by using radial stress instead of axial stress or enabling the dismounting force not to directly act on the skin of a patient, or changing the stress mode, concentrating the dismounting force in the mechanism, or increasing the dismounting force reducing coefficient, reducing the traction force caused to the skin and reducing the disturbance caused to the stoma; the sealing mechanism is used for closing one end of the collecting bag in a turnover and bonding mode, a hydrocolloid dressing ring is fixedly connected to one side of the ostomy chassis, which is far away from the outer liner bag, and the hydrocolloid dressing ring is used for absorbing wound surface seepage and expanding to form a gel barrier and has bonding property, and mechanical pretightening force is formed by using the expansion characteristic of the hydrocolloid dressing ring and the quick-release connecting mechanism, so that dynamic sealing is formed. Further preferably, the sealing mechanism comprises a first patch, a second patch, a sealing sheet, a first sealing strip and a second sealing strip; The first patch and the second sealing strip are adhered and fixed to one side, close to the ostomy chassis, of the collecting bag, the second patch and the sealing strip are adhered and fixed to the other side of the collecting ba
