Description

Technical Field

[0001] The utility model relates to the technical field of feces drainage, in particular to a feces drainage tube and a sampling joint thereof. Background Art

[0002] Fecal drainage bag is a medical device used clinically to drain feces for patients with fecal incontinence. Fecal incontinence is common in critically ill patients, comatose patients, and patients who have lost consciousness. Because the anal sphincter of patients with fecal incontinence is relaxed, they cannot control their stool. If there is no drainage, the perianal skin is easily soaked, prone to redness, swelling, erosion, even ulcers, eczema and other inflammations. The drainage bag drains the feces in the patient's body into the fecal collection bag through a drainage tube partially built into the anus, thereby reducing the workload of clinical nursing.

[0003] The fecal drainage device requires a person to manually deliver the balloon to the human anus, and then inflate the balloon through the filling pipe to make the balloon barrier and seal. Human feces are diverted from the drainage tube to the feces collection bag. The sealing of the sampling port on the drainage tube of the existing fecal drainage device is not good. When the front end of the syringe is inserted into the sampling port, the sampling port is prone to leakage, causing environmental pollution. Utility Model Content

[0025] Reference Figure 3In the specific use of the fecal drainage tube of this embodiment, first connect the drainage tube to the drainage bag and fix the drainage bag in a suitable position on the bed. Then apply lubricant to the patient's anus, slowly insert the balloon with the air emptied into the anus, fill the indwelling balloon with physiological saline or sterile water, fill the balloon, gently pull the drainage tube outward, and after feeling resistance, you can confirm that the balloon has been fixed in the anus. When taking out, draw out the physiological saline or sterile water in the indwelling balloon to empty the balloon. When it is necessary to sample the feces in the drainage tube, insert the front end 100 of the syringe into the sampling channel, squeeze the elastic flap to deform it and open it, and the sealing ring is sealed with the outer wall of the front end 100 of the syringe. At this time, sample is taken from the drainage tube through the syringe. After the sampling is completed, the syringe is pulled out, and the elastic flap automatically closes under the elastic action.

[0026] In this embodiment, the fecal drainage tube and its sampling connector are proposed, the sampling connector includes a mounting portion, the mounting portion is provided with a sampling channel, one end of the sampling channel is provided with a valve structure composed of multiple elastic flaps, the multiple elastic flaps cooperate to close the sampling channel in a natural state, the inner wall of the sampling channel is provided with a sealing ring, and the sealing ring and the elastic flap are separated by a preset gap. Through the above-mentioned optimized design of the sampling connector, the sampling channel is closed by the valve structure composed of multiple elastic flaps. When sampling, the front end of the syringe is inserted into the sampling channel, and when the elastic flap is squeezed to deform and open, the sampling channel is sealed with the outer wall of the front end of the syringe through the sealing ring, so as to avoid leakage at the position where the syringe and the sampling channel cooperate during sampling, and avoid pollution to the environment.

[0027] In a specific embodiment, the sampling connector 1 further includes a connecting portion and a sealing portion which are sequentially connected to the mounting portion, and the sealing portion is provided with a sealing plug 2 for sealing the sampling channel. After the sampling is completed, the sampling channel is sealed by the sealing plug of the sealing portion to further prevent leakage.

[0028] Furthermore, a pulling portion is provided on one side of the sealing portion away from the connecting portion, and an anti-slip protrusion 3 is provided on the pulling portion for easy operation.

[0029] Referring to the soil, in other specific embodiments, when inserting the balloon into the patient's body, the doctor usually wears medical rubber examination gloves, applies lubricant to the patient's anus, grasps the emptied balloon with fingers, and inserts it into the patient's body. In this process, since the balloon and the tube body are usually made of silicone material, the front end of the tube body is soft and difficult to operate, and the doctor needs at least two fingers to insert the balloon, which increases the possibility of injury to the patient.

[0030] Therefore, in the specific design of the drainage catheter of this embodiment, an outer insert sheet 6 is designed on the outer wall of the tube body, and the outer insert sheet 6 is located at one end of the tube body 4 close to the indwelling balloon 5. The edge of the outer insert sheet 6 is fixed to the outer wall of the tube body 4, and a finger sleeve insertion opening for finger insertion is formed between the outer insert sheet 6 and the outer wall of the tube body 4. The doctor inserts the finger into the finger sleeve and slowly inserts the balloon into the anus, which is convenient for operation and reduces damage to the patient.

[0031] In the specific design of the outer insert sheet, the outer insert sheet 6 is located between the indwelling balloon 5 and the outer wall of the tube body 4 .

[0032] In a further specific design, the tube body 4 is further provided with an inner insert sheet 7 extending along the axial direction of the tube body 4, the inner insert sheet 7 is arranged correspondingly to the outer insert sheet 6, the edges of the inner insert sheet 7 on both sides are connected to the inner wall of the tube body 4, and a cleaning channel is formed between the inner insert sheet 7 and the inner wall of the tube body 4. In order to facilitate the cleanliness of the tube body during use, a cleaning channel is usually provided in the tube body. The cleaning channel is formed in the tube body by the inner insert sheet, the outer insert sheet is arranged at the position of the cleaning channel, and the inner insert sheet reinforces the position of the tube wall where the outer insert sheet is located, thereby extending the life of the position of the outer insert sheet for repeated use.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
