Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a three-lumen colon flushing tube. Background Art

[0002] Patients with colorectal obstruction, colorectal stenosis, long-term bedridden patients with difficulty defecating, and patients who are unable to defecate and pass gas after surgery usually have an intestinal irrigation tube placed in the intestinal cavity to irrigate and drain the intestines, helping the patient to expel accumulated stool in the intestines, thereby alleviating discomfort such as abdominal distension and pain, and preventing intestinal mucosal damage, bleeding, and intestinal perforation.

[0003] However, the insertion depth of ordinary anal irrigation tubes is about 10 cm from the anus, which is difficult to insert deeper and farther, and cannot better flush and drain the stool accumulated deep inside. It is even more difficult to insert the tube for patients with intestinal obstruction or intestinal stenosis. The tube is easy to twist and bend in the intestinal cavity, increasing the risk of intestinal mucosal damage, bleeding or intestinal perforation, and cannot help patients solve the fundamental problem. To this end, the utility model provides a three-chamber colon irrigation tube. Utility Model Content

[0004] The utility model provides a three-lumen colon flushing tube, which solves the technical problems that the existing common anal canal flushing tubes have poor placement depth and position, and the flushing tubes are prone to twisting and folding in the intestinal cavity, increasing the risk of intestinal mucosal damage, bleeding or intestinal perforation, thereby failing to achieve the purpose of efficiently flushing the accumulated stool in the intestinal cavity. At the same time, a three-lumen colon flushing tube with high placement efficiency, better placement depth and position, and efficient cleaning of accumulated stool is provided.

[0005] The utility model aims to provide a three-chamber colon irrigation tube, comprising an irrigation tube, on which a balloon is embedded, the tail end of the irrigation tube is connected with a negative pressure suction joint, and an irrigation chamber joint and a balloon chamber joint are connected on the tube wall at the tail end of the irrigation tube, characterized in that a binding wire is provided on the irrigation tube.

[0007] As a preferred embodiment, the binding wire is arranged at the head end of the flushing pipe.

[0008] As a preferred embodiment, the binding thread is a non-absorbable surgical suture.

[0009] As a preferred implementation, the diameter of the binding wire is 0.1 cm.

[0010] As a preferred implementation, the binding wire is clamped by a biopsy forceps.

[0011] As a preferred embodiment, physiological saline or contrast agent is provided in the balloon.

[0012] As a preferred embodiment, the distance between the balloon and the binding wire is 3 to 6 cm.

[0013] As a preferred embodiment, the length of the flushing tube is 35 cm.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0019] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention is further described below in conjunction with specific embodiments and drawings.

[0020] In the description of the present invention, it should be noted that the terms "head", "tail", "inside", "outside", "upper", "middle", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0021] The utility model provides a three-cavity colon irrigation tube, such as Figure 1 As shown, it includes a flushing tube 1, which is made of silicone material, has stable chemical properties, good adsorption performance, a rounded head end, a high degree of transparency of the tube body, and can be developed under X-rays, making it easy to confirm the drainage status and retention position. The flushing tube 1 adopts a 24Fr model, and the tube diameter is thick enough to better flush and prevent blockage; a balloon 2 is embedded in the flushing tube 1, and a negative pressure suction joint 3 is connected to the tail end of the flushing tube 1, and a flushing cavity joint 4 and a balloon cavity joint 5 are connected on the tube wall at the tail end of the flushing tube 1, and it is characterized in that a binding wire 6 is provided on the flushing tube 1. Under the visual guidance of the colonoscope, clamp the suture 6 with the biopsy forceps 7, and pull the three-lumen colon irrigation tube with the binding wire 6 to the distal end of the colorectal stenosis. After determining the position, use a 50mL syringe to inject 20-30mL of normal saline or contrast agent into the balloon cavity joint 5. Its functions are to fix the irrigation tube 1 and to confirm the position of the irrigation tube 1 through imaging. After the biopsy forceps 7 and the endoscope are withdrawn from the body, the insertion length of the irrigation tube 1 is recorded, and the irrigation tube 1 is fixed externally with the cut 3M tape. The irrigation cavity joint 4 is flushed with an infusion tube, and the negative pressure suction tube is connected to the negative pressure suction joint 3 for suction, thereby expelling the feces accumulated in the intestinal cavity from the body.

[0022] In order to facilitate the traction of the flushing tube 1 and place the flushing tube 1 at a suitable position, the head end of the binding wire 6 is 2 cm away from the flushing tube 1. The binding wire 6 set on the flushing tube 1 is clamped with a biopsy forceps 7 and sent to the distal end of the colorectal stenosis to prevent the flushing tube 1 from slipping out easily.

[0023] In order to achieve effective placement of the three-lumen colon irrigation tube, the binding wire 6 is set at the head end of the irrigation tube 1. Under endoscopy, the binding wire 6 set at the head end of the feeding tube 1 is clamped with a biopsy forceps 7 to deliver the irrigation tube 1 to the distal end of the colorectal stenosis.

[0024] In order to prevent the binding wire from breaking, the binding wire 6 is a non-absorbable surgical suture; the material of non-absorbable suture is tougher and harder than that of absorbable suture, and is not easy to break during binding; absorbable sutures are easily degraded by hydrolysis, and non-absorbable sutures can always remain intact. If the pipe falls off and needs to be adjusted, there is no need to pull out the pipe and re-bind the suture; non-absorbable sutures are cheaper than absorbable sutures, saving costs.

[0025] In order to further flush the feces accumulated in the colon and improve the clamping accuracy of the flushing tube 1, the diameter of the binding wire 6 is about 0.1 cm, which is within the clamping range of the biopsy forceps 7.

[0026] In order to ensure that the flushing tube 1 can reach the designated position and clean the feces accumulated in the intestine at the designated position, the binding wire 6 is clamped by the biopsy forceps 7. Under the colonoscopy, the biopsy forceps 7 clamp the binding wire 6 and guide the flushing tube 1 to the designated position from the head end of the flushing tube 1.

[0027] In order to effectively clean the feces in the intestine or confirm the placement of the flushing tube 1, physiological saline or contrast agent is set in the balloon 2. First, physiological saline is used to clean the accumulated feces in the intestine, and second, the position of the flushing tube 1 is confirmed by imaging under the action of the contrast agent.

[0028] In order to ensure that the examining physician can confirm the placement of the intestinal flushing tube 1, the distance between the balloon 2 and the binding wire 6 is 3 to 6 cm. Within this distance range, the physiological saline in the balloon 2 can effectively act on the feces accumulation site in the intestine; or the placement of the flushing tube 1 can be confirmed by imaging under the action of contrast agent.

[0029] In order to further ensure that the flushing tube 1 can be placed in any position in the intestine that requires flushing, the length of the flushing tube 1 is 35 cm.

[0030] In order to relieve the discomfort such as abdominal pain and bloating in patients with colorectal obstruction, colorectal stenosis, long-term bedridden patients with difficulty in defecation, patients who cannot defecate and pass gas after surgery, or patients who are ineffective with drug treatment, and to prevent intestinal mucosal damage, bleeding, and intestinal perforation, when in use, a binding line 6 is set at the head end of the three-lumen colon irrigation tube of the utility model, and a clamping length of 2 cm is reserved. Under the visual guidance of the colonoscope, a biopsy forceps 7 is used to clamp the suture 6, and the three-lumen colon irrigation tube with the binding line 6 is pulled to the distal end of the colorectal stenosis. After determining the position, a 50mL syringe is used to inject 20-30mL of normal saline or contrast agent into the balloon cavity joint 5. Its functions are to fix the irrigation tube 1 and to confirm the position of the irrigation tube 1 through imaging. After the biopsy forceps 7 and the endoscope are withdrawn from the body, the length of the irrigation tube 1 is recorded, the irrigation tube 1 is fixed externally with a cut 3M tape, the irrigation tube 1 is flushed with an infusion pipeline at the irrigation cavity joint 4, and a negative pressure suction tube is connected to the negative pressure suction joint 3 for suction, thereby expelling feces accumulated in the intestinal cavity from the body.

[0031] Clinical application examples

[0032] Application Example 1

[0033] A patient in the ICU had congested and swollen intestinal mucosa after prostate cancer surgery. Coupled with long-term bed rest, he was unable to defecate and had unbearable abdominal distension. After an ordinary intestinal irrigation tube failed, the auxiliary ligature was clamped with a biopsy forceps and brought into the intestine under the visualization of the colonoscope. After passing through the edematous and narrow part of the intestine, the water bag was inflated and fixed, and the irrigation chamber connector was connected to the infusion tube for irrigation. The other negative pressure suction chamber connector was connected to the central negative pressure for continuous suction. After repeated flushing, a large amount of brown paste-like stool was induced, and the abdominal distension and abdominal pain were significantly relieved compared with before, and the abdominal circumference was also reduced compared with before.

[0034] Application Example 2

[0035] A CCU patient was admitted to the hospital due to an acute myocardial infarction caused by coronary heart disease and required ECMO technology-assisted treatment. The patient had a distended abdomen, weakened bowel sounds, and was unable to pass gas through the anus. If the constipation could not be resolved, it would lead to persistent myocardial ischemia, which would in turn induce another myocardial infarction. Relevant imaging suggested intestinal obstruction, and an ordinary anal tube was placed for anal gas discharge, but the effect was not good. After consultation with our department, under the visual guidance of colonoscopy, the suture set at the head of the irrigation tube was clamped with biopsy forceps and inserted into the intestinal cavity with a depth of about 30 cm. After fixation, through repeated flushing, it was seen that the patient drained a small amount of yellow flocculent feces. Every day, 0.9% saline 1000mL + paraffin oil 40mL was given for slow enema through a three-lumen colon irrigation tube, connected to a negative pressure suction bottle for suction, and an equal amount of yellow liquid stool was seen to be drawn out. The patient also had obvious anal gas discharge and defecation, and abdominal distension was also reduced compared to before.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
