Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to an anti-clogging enema fecal drainage device. Background Technology

[0002] A fecal drainage device is a specially designed device for removing feces from the human or animal body. It has wide applications in the medical field and mainly consists of a drainage bag and a drainage tube. The drainage bag is a container used to collect excrement, usually with a certain capacity that can be replaced as needed. The drainage tube is a tube connecting the patient's anus and the drainage bag, typically of a certain length and with flexibility to ensure patient comfort. A balloon is located at the head of the drainage tube to secure it inside the anus.

[0003] Current fecal drainage devices are prone to blockage or poor flow when encountering viscous stool. Existing solutions typically involve creating a flushing port on the drainage tube to flush the tube. The flushing water flows along the tube to its end to dilute the stool. However, the head of the drainage tube enters the anus, while the flushing port is located on the outside of the anus, some distance from the head of the drainage tube. This results in a weak flushing effect on the head of the drainage tube. In cases of severe blockage, it may be necessary to reinsert the tube, increasing patient discomfort. Utility Model Content

Detailed Implementation

[0019] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figure 1 and 2 As shown, this embodiment discloses an anti-clogging enema fecal drainage device, including a drainage tube 1 made of soft material. The end of the drainage tube 1 is provided with a connecting cap 13, which is integrally connected to the drainage tube 1. The connecting cap 13 can be connected to a drainage bag by threads. A balloon 2 is connected to the outer wall of the head section of the drainage tube 1. The balloon 2 is connected to a balloon inflation catheter 3. A flushing tube 4 is provided on the inner wall of the head section of the drainage tube 1. The flushing tube 4 is arranged in a spiral shape. A plurality of flushing holes 401 are provided on the outer wall of the flushing tube 4. The tail end of the flushing tube 4 is connected to a water injection catheter 5. The water injection catheter 5 penetrates the tube wall of the flushing tube 4 and extends to the outside.

[0022] When in use, if the feces are viscous, it can cause poor drainage and blockage of the drainage pipe 1. In this case, a spiral flushing pipe 4 attached to the main body of the feces drainage device is used. This flushing pipe 4 is characterized by its spiral distribution along the inner side of the drainage pipe 1. The flushing pipe 4 is a circular hollow pipe with several flushing holes 401, the openings of which face the center of the drainage pipe 1. By injecting water into the flushing pipe 4, the feces are diluted to ensure smooth drainage. The flushing water flows along the drainage pipe 1 to its end, thus achieving the purpose of flushing the entire drainage pipe 1 and effectively improving the flushing effect.

[0023] In this embodiment, the inner part of the drainage tube 1 head section is provided with an annular cavity 6, and a plurality of drug administration holes 7 are arranged in an annular pattern on the end face of the drainage tube 1 head section. Each drug administration hole 7 is connected to the annular cavity 6, and the annular cavity 6 is connected to the drug injection channel 8 embedded in the wall of the drainage tube 1. The end of the drug injection channel 8 is connected to the drug injection catheter 9 located outside the drainage tube 1. If an enema is required, the enema agent is injected through the drug injection catheter 9. The enema agent is dispersed through the annular cavity 6 to each drug administration hole 7, and finally injected into the patient's body through each drug administration hole 7, making the drug administration more uniform.

[0024] The drainage tube 1 is usually made of silicone to ensure that it has a certain degree of flexibility and is easy to lay. However, since the head of the drainage tube 1 is inserted into the anus, it needs to have a certain degree of support. Therefore, in this embodiment, the wall thickness of the head of the drainage tube 1 is greater than the wall thickness of other parts of the tube.

[0025] To allow medical staff to visually observe the depth of the drainage tube's first segment inserted into the anus, a limit mark 10 can be provided on the outer wall of the drainage tube's first segment. In this embodiment, the limit mark 10 is a ring-shaped color ring.

[0026] In this embodiment, a sampling port 11 is provided on the outer wall of the drainage tube 1, and a cap 12 is provided on the sampling port 11. Fecal samples can be extracted through the sampling port 11 for testing.

[0027] In order to better fix the head of the drainage tube 1 inside the anus, in this embodiment, a ring support 14 is fitted on the head of the drainage tube 1. The ring support 14 is located behind the balloon 2. A fixing strap 15 is provided on the ring support 14. The fixing strap 15 is tied to the patient's waist. The ring support 14 is located at the anus to prevent the balloon 2 from accidentally dislodging.

[0028] It should be noted that the balloon 2 in this embodiment is a common structural form.

[0029] Example 2

[0030] A balloon typically becomes spherical when inflated with water. In this case, the balloon can be designed as an umbrella-shaped structure, or more specifically, an inverted umbrella shape, such as... Figure 3 and 4 As shown, balloon 2 includes an outer membrane 201 and an inner membrane 202. The lower edges of both the outer membrane 201 and the inner membrane 202 are connected to the outer wall of the drainage tube 1, and the upper edges of the outer membrane 201 and the inner membrane 202 are connected. The outer membrane 201, the inner membrane 202, and the drainage tube 1 enclose a membrane cavity 203, which is connected to the balloon inflation catheter 3. Several support ribs 204 are provided on the membrane wall of the inner membrane 202, and the support ribs 204 are arranged in a ring around the drainage tube 1. The support ribs 204 and balloon 2 are an integral structure. The support ribs 204 have a certain elasticity, and their ends exert a certain tightening force on balloon 2, so that the upper part of balloon 2 is in a contracted state when it is not inflated, and balloon 2 is teardrop-shaped as a whole.

[0031] Without water, balloon 2 has certain folds and is generally teardrop-shaped, which increases the space for expansion after the balloon is inflated. When water is injected, balloon 2 inflates, and the supporting ribs 204 expand outward due to the inflation of balloon 2, forming a bowl-shaped structure. This can improve the fixation effect of balloon 2 and also prevent the possibility of excrement leakage.

[0032] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
