Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a negative pressure drainage device for stoma. Background Art

[0002] Stoma reduction refers to forming an opening by sewing the end of the intestine to the abdominal wall through surgery for fecal excretion due to the need of disease treatment. In the early stage, a simple drainage bag was covered and pasted on the fistula opening to handle the feces excreted from the intestine. However, due to reasons such as poor adhesion of the simply pasted drainage bag, infection occurred at the fistula opening, causing inflammation of the skin around the fistula. Later, after improvement, a stoma chassis was set at the stoma, and a drainage bag was fixed on the chassis. The drainage tube was led out from the intestine and passed through the drainage bag, so that feces were discharged from the drainage tube. This method greatly reduced the probability of incision infection. However, pollutants still occasionally leaked out of the drainage bag, infecting the incision and the skin around the incision. In the prior art, improper treatment of the stoma reduction opening would exacerbate the patient's condition. Chinese Patent No. 201620121947.2 discloses a negative pressure drainage device for intestinal stoma. This drainage device reduces the pollution of the skin around the stoma by excreta by extending the drainage tube into the intestine and combining with a negative pressure drainage device, greatly reducing the infection rate of the incision. However, extending the drainage tube into the intestine may cause blockage of pollutants in the intestine, and the drainage cover disclosed in this utility model may leak, causing some unnecessary troubles.

[0021] As mentioned in the background art, for the existing ostomy negative pressure drainage device, inserting the drainage tube into the intestine may cause blockage of pollutants in the intestine, and there may be a leakage situation in the drainage cover disclosed in this utility model, thus causing some unnecessary troubles. For this reason, this utility model provides an ostomy negative pressure drainage device, which has a simple structure, is convenient to operate, is convenient to disassemble, and can reduce the infection risk suffered by patients. The ostomy negative pressure drainage device of this utility model will be introduced in detail below with reference to the accompanying drawings.

[0022] See Figures 1 to 2 As shown, this utility model provides an ostomy negative pressure drainage device. Compared with the prior art, this ostomy negative pressure drainage device is also composed of a negative pressure drainage device 6, an ostomy chassis 2, a water tank 4, a connecting pipe 3, a first hose 71, a second hose 72, and a storage chamber 5. Different from the prior art, the ostomy chassis 2 includes an adhesive part 20 and a connecting part 21. The adhesive part 20 can be fixed on the human body 8, and a first one-way valve 11 is provided in the connecting part 21; one end of the connecting pipe 3 close to the ostomy chassis 2 is provided with a water inlet 30, the water tank 4 is connected to the water inlet 30 through the first hose 71, and a second one-way valve 12 is provided in the water inlet 30; a fluid inlet 51 and a connection port 52 are provided in the storage chamber 5. The fluid inlet 51 is connected to the ostomy chassis 2 through the connecting pipe 3, the connection port 52 is connected to the negative pressure drainage device 6 through the second hose 72, and a third one-way valve 13 is provided in the fluid inlet 51.

[0023] When actually using the ostomy negative pressure drainage device of this utility model, first align the connecting part 21 with the ostomy position, and then surround the patient's body with the adhesive part 20 to make it stick firmly. Finally, connect the ostomy chassis 2 and the storage chamber 5 with the connecting pipe 3, connect the water tank 4 and the connecting pipe 3 with a hose, and connect the storage chamber 5 and the negative pressure drainage device 6 with a hose. After ensuring that the device is connected, turn on the negative pressure drainage device 6 to create a negative pressure in the storage chamber 5. At this time, the one-way valve 1 will open under the action of the negative pressure, and the pollutants in the intestine 9 will flow into the storage chamber 5 along the connecting pipe 3 under the action of the negative pressure.

[0024] At the same time, the water in the water tank 4 can flow into the connecting pipe 3 through the water inlet 30 to wash the connecting pipe 3 and prevent the connecting pipe 3 from being blocked.

[0025] Further, the one-way valve 1 is made of a soft material and is opened under the negative pressure generated by the negative pressure drainage device 6. That is to say, when the negative pressure drainage device 6 is closed, the one-way valve 1 will return to its closed state again. The one-way valve 1 returning to its closed state has two functions. First, it prevents the pollutants in the intestine 9 from being discharged at any time, and the patient only needs to discharge the pollutants regularly. Second, after the storage chamber 5 is full and the storage chamber 5 is removed, the automatic closing of the one-way valve 1 can prevent the pollutants from overflowing and at the same time prevent the odor from emitting from the storage chamber 5. In addition, after the one-way valve 1 is closed, it can prevent the water in the water tank 4 from continuing to flow into the connecting pipe 3, so as to achieve the effect of saving water.

[0026] Further, the pasting part 20 and the connecting part 21 are integrally formed. The integrally formed design simplifies the structure of the ostomy negative pressure drainage device 6, making the disassembly and installation of the device more convenient.

[0027] Further, in order to prevent the pollutants discharged from the intestine 9 from entering the water tank 4 through the water inlet 30, the included angle between the water inlet 30 and the connecting part 21 is 30° - 60°.

[0028] Further, in order to increase the service life of the one-way valve 1, a switch knob 40 is provided at one end of the water inlet 30. When water is not actually needed, the connection between the water tank 4 and the connecting pipe 3 can be closed through the switch knob 40 to prevent the one-way valve 1 from being under the action of water pressure all the time.

[0029] Further, the connecting pipe 3 is detachably connected to the ostomy chassis 2 and the storage chamber 5; the hose is detachably connected to the connecting pipe 3, the water tank 4, the storage chamber 5 and the negative pressure drainage device 6. That is to say, the connecting pipe 3, the storage chamber 5 and the negative pressure drainage device 6 can all be replaced according to actual needs to facilitate the replacement of the storage chamber 5 and the maintenance of the device.

[0030] Further, in order to prevent the pollutants in the storage chamber 5 from entering the negative pressure drainage device 6, a splash-proof net 50 is provided at one end of the storage chamber 5 close to the negative pressure drainage device 6. In order to prevent the odor in the storage chamber 5 from emitting when the storage chamber 5 is replaced, a deodorant substance can be placed in the interlayer of the splash-proof net 50.

[0031] Further, the storage chamber 5 includes a storage bag, a storage vessel, etc.

[0032] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "beneath" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations of the spatial relative descriptions used herein will be made.

[0033] In addition, it should be noted that the use of terms such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. Without further statement, the above terms have no special meaning, and thus should not be construed as limiting the protection scope of the present utility model.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
