Description

Technical Field

[0001] The invention relates to the technical field of medical colostomy bags, in particular to a convenient-to-use colorectal colostomy sub-packaging drainage bag. Background Art

[0002] For wounds in the abdominal cavity or chest cavity that cannot be closed due to high internal pressure, or wound surfaces formed due to skin ulceration, it is usually necessary to treat the exudate from the above wounds. Domestic medical institutions generally use gauze to apply to the wounds that cannot be closed, which can easily lead to large-scale overflow of exudate, leading to skin infection and aggravating wound ulceration. When using a few existing drainage bags, the connector is directly inserted into the drainage site of the patient's body. Direct insertion of the connector will aggravate the patient's wound pain, increase the patient's burden, and in severe cases affect the patient's treatment progress.

[0036] The following is a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0037] Example 1

[0038] A convenient-to-use colorectal ostomy sub-packaging drainage bag, comprising: an ostomy bag 1 and an ostomy bag installation mechanism;

[0039] like Figure 3 As shown, the ostomy bag 1 includes a bag body 2, which is used to collect gas, liquid and solid discharged from the wound. The bag body 2 is provided with a connection hole, and a connecting portion 3 is fixedly connected to the connection hole. The connecting portion 3 is detachably connected to the ostomy bag installation mechanism. The bag body 2 is detachably connected to the ostomy bag installation mechanism through the connecting portion 3. The ostomy bag installation mechanism is fixed on the wound, and impurities discharged from the body enter the bag body 2 through the ostomy bag installation mechanism.

[0040] like Figure 1-2 As shown, the ostomy bag installation mechanism is used to be detachably connected to the connecting part 3, and the ostomy bag installation mechanism includes a diversion connecting tube 4, a cleaning shrinking part, an outer water bag 9, an outer air bag 10 and a control valve 11:

[0041] A flow guiding connecting tube 4, wherein the flow guiding connecting tube 4 is detachably and hermetically connected to the connecting portion 3, and the flow guiding connecting tube 4 is used to cover the wound of the patient;

[0042] The cleaning shrinking member is used to close the diversion connecting tube 4, and is arranged around the inner wall of the diversion connecting tube 4; the cleaning shrinking member includes an inner air bag 5 and an inner water bag 6 arranged side by side along the axial direction of the diversion connecting tube 4, and the inner air bag 5 is used to be close to the skin, and the inner air bag 5 closes the diversion connecting tube 4 after expansion; the inner air bag 5 is used to close the diversion connecting tube 4 when the fistula bag 1 is replaced, which is convenient for replacing the fistula bag 4;

[0043] A cleaning hole 7 is provided on the inner water bag 6, near the inner air bag 5, and the inner water bag 6 is used to clean the bottom wall of the inner air bag 5, so as to keep it clean during replacement and reduce the psychological pressure of the patient;

[0044] The inner air bag 5 and the inner water bag 6 are respectively provided with a connecting pipe 8, and both connecting pipes 8 penetrate the side wall of the flow-guiding connecting pipe 4, so that the external gas and water enter the inner air bag 5 and the inner water bag 6 respectively through the connecting pipe 8;

[0045] The outer water bag 9 is connected to the inner water bag 6 through any of the connecting pipes 8. Clean water is stored in the outer water bag 9. After squeezing the outer water bag 9, the clean water enters the inner water bag 6 through the connecting pipe 8 and sprays water onto the bottom wall of the inner air bag 5 through the cleaning hole 7 to clean the bottom wall of the inner air bag 5, so as to keep it clean when replacing it.

[0046] The outer airbag 10 is connected to the inner airbag 5 through another connecting pipe 8, and the outer airbag 10 is used to provide gas to the inner airbag 5;

[0047] The control valves 11 are respectively arranged on the two connecting pipes 8 to facilitate controlling the states of the inner air bag 5 and the inner water bag 6;

[0048] The diversion connecting tube 4 is provided with a connecting belt 18, and the connecting belt 18 is detachably connected by a buckle. The connecting belt 18 is used to connect with the human body. After the connection, it is convenient to fix the fistula bag installation mechanism on the wound.

[0049] Furthermore, a fitting suction cup 19 is detachably connected to the outer wall of the diversion connecting tube 4, near the inner airbag 5. The fitting suction cup 19 is used to be adsorbed on the skin surface. The fitting suction cup 19 is a cuttable suction cup, which is cut according to the size of the patient's wound to avoid large amounts of impurities contacting the skin. An annular scale is provided on the fitting suction cup 19, which facilitates cutting to uniform size. The fitting suction cup 19 can be stably bonded to the skin, and compared with the connecting belt 18, it has more excellent connection stability.

[0050] How it works

[0051] When in use, the fitting suction cup 19 is cut according to the size of the patient's wound, and then the guide connecting tube 4 is stably adhered to the surface of the fitting suction cup 19, so that the cut opening is located in the guide connecting tube 4, and the connecting part 3 is screwed on the guide connecting tube 4 to connect the guide connecting tube 4 to the bag body 2, and then it can be used; or, the guide connecting tube 4 is covered on the wound, connected to the human body through the connecting belt 18, the guide connecting tube 4 is kept stable, and the connecting part 3 is screwed on the guide connecting tube 4 to connect the guide connecting tube 4 to the bag body 2.

[0052] When the ostomy bag 1 needs to be replaced, the air is first exhausted into the inner air bag 5 through the outer air bag 10, so that the inner air bag 5 expands and the diversion connecting tube 4 is closed, and then water is squeezed into the inner water bag 6 through the outer water bag 9, and the clean water is sprayed onto the bottom wall of the inner air bag 5 through the cleaning hole 7. After the bottom wall of the inner air bag 5 is cleaned, the connecting part 3 is removed from the diversion connecting tube 4, and then a new ostomy bag 1 is screwed on again.

[0053] Example 2

[0054] On the basis of Example 1, in order to provide sufficient storage space for the bag body 2 and avoid the bag body 2 from bursting due to the patient's discharge of a large amount of gas or liquid, a pressure relief valve 12 is provided on the bag body 2, and the bottom of the bag body 2 is detachably connected to an additional bag 14 through a circulation tube 13. A liquid one-way valve 15 is provided in the circulation tube 13. The liquid one-way valve 15 ensures that liquid can only enter the additional bag 14 from the bag body 2, thereby maintaining a large storage space in the bag body 2. Even if a sudden large amount of liquid or gas is discharged due to the colostomy, the bag bursting can be effectively avoided; in addition, a pressure relief valve 12 is also provided, which is used to discharge the gas in the bag body 2 to avoid the accumulation of a large amount of gas in the bag body 2 and then causing the bag bursting phenomenon; the fistula bag 1 and the diversion connecting tube 4 are detachably screwed, and a sealing strip is provided at the screw connection to facilitate the replacement of the additional bag 14. At the same time, the screw connection method is also convenient for patients to operate by themselves.

[0055] Example 3

[0056] On the basis of Example 2, considering that the ostomy bag 1 is relatively expensive and not all cases require the use of the ostomy bag 1, for example, if the patient's stool is relatively regular and formed, a disposable, economical and cheap inner bag is installed at this time. After the use is finished and taken out, the ostomy bag is still clean and usable, which effectively saves the cost of the patient to purchase the ostomy bag 1. Based on the above reasons, the structure of the connecting portion 3 is designed, such as Figure 4-6 As shown, the connecting part 3 is a hard plastic connecting part, and the connecting part 3 includes:

[0057] An internal pipe 20, the internal pipe 20 is fixedly connected to and communicated with the bag body 2;

[0058] The outer wall of the external pipe 21 is detachably connected to the diversion connecting pipe 4. The outer wall of the external pipe 21 is provided with an external thread, and the inner wall of the diversion connecting pipe 4 is provided with an internal thread, and the two are threadedly connected; the inner wall of the external pipe 21 is detachably connected to the inner pipe 20, such as Figure 5 As shown, the inner wall of the external tube 21 is provided with a buckle, and the outer wall of the internal tube 20 is provided with a slot corresponding to the buckle. After a certain force is applied to the external tube 21, the external tube 21 can be buckled on the internal tube 20, and a sealing strip 16 is provided at the top of the inner wall of the internal tube 20 to prevent liquid leakage.

[0059] An inner bag 22 is sandwiched between the inner tube 20 and the outer tube 21, and the inner bag 22 is located in the bag body 2. Figure 6 As shown, when in use, first place the closed end of the inner bag 22 in the bag body 2, then extend the open end of the inner bag 22 from the inner tube 20, and turn the open end of the inner bag 22 from the inside to the outside and fit it on the inner tube 20, and then buckle the outer tube 21 on the inner tube 20. At this time, the inner bag 22 is sleeved on the inner tube 20, and the side wall is located between the inner tube 20 and the outer tube 21, so that the inner bag 22 is stable. If the inner bag is full, first exhaust the air into the inner air bag 5 through the outer air bag 10, so that the inner air bag 5 expands, and the diversion connecting tube 4 is closed, and then the outer water bag 9 is used to squeeze water into the inner water bag 6, and the clean water is sprayed onto the bottom wall of the inner air bag 5 through the cleaning hole 7 to clean the bottom wall of the inner air bag 5, and then the external tube 21 is removed from the diversion connecting tube 4, the external tube 21 is removed from the inner tube 20, and the inner bag 22 can be taken out.

[0060] A sterilization-free layer 17 is detachably connected to the inner wall of the inner pipe 20 , and the sealing strip 16 is located above the sterilization-free layer 17 . The sterilization-free layer 17 realizes a clean connection without the need for sterilization, and the sealing strip 16 prevents liquid leakage.
