Description

Technical Field

[0001] The utility model belongs to the technical field of anal canal drainage treatment, and specifically relates to a novel transanal drainage device. Background Art

[0002] Colorectal cancer is a disease in which malignant (cancerous) cells develop in the tissues of the colon or rectum.

[0003] Radical surgery is the main treatment for rectal cancer patients. Currently, the most commonly used surgical method is low anterior rectal resection. For a period of time after the operation, medical staff will place an anal drainage device in the patient's anus to reduce the occurrence of complications such as anastomotic fistula and decreased bowel control.

[0004] In the prior art, after the universal anal tube made of rubber hose is inserted through the patient's anus, it is often necessary to use medical tape to stick to the perianal skin for external fixation because the tube does not have its own fixing device. However, during use, the patient's skin and the medical tape are soaked by body fluids, and the tape often becomes loose. In order to fix the tube more firmly, some medical staff will use needle and thread suturing to fix the anal tube to the patient's perianal skin. Although this method can enhance the tube fixation effect, it greatly increases the patient's pain and discomfort.

[0005] The patent document with the announcement number CN 214550433 U discloses a transanal drainage device, including a drainage tube, characterized in that: the top and bottom ends of the drainage tube are respectively provided with an upper port and a lower port, the outer surface of the drainage tube is sleeved with a sleeve, the outer surface of the sleeve is fixed with a collection bucket, the bottom of the collection bucket is connected with a connecting pipe, there are two connecting pipes, and the bottom ends of the two connecting pipes are connected with the same collection bag. This patent solves the above-mentioned problems existing in the prior art, and an outer surface sleeve and a fixing sticker are added, but its fixing function is relatively simple, and there is still a risk of loosening and displacement of the pipe. Therefore, it is necessary to design a new transanal drainage device to achieve a multi-dimensional and high-strength pipe fixing effect. Summary of the invention

[0006] The utility model aims to provide a novel transanal drainage device. By using the novel transanal drainage device, the anal canal after being inserted into the anus can be clamped and fixed by a silicone gel fixing patch and a water-filled air bag to avoid accidental falling out.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A novel transanal drainage device comprises an anal tube assembly and a drainage device, wherein the anal tube assembly comprises an anal tube, a support column tube and an anal tube joint tube, wherein the anal tube is connected to the support column tube, the anal tube joint tube and the support column tube are slidably sleeved and can be fixed by a buckle, a silicone gel fixing patch is provided on the support column tube, and a water-injectable air bag is provided on the outer periphery of the anal tube joint tube.

[0009] Connections between the anal tube, support column tube and anal tube connector tube:

[0010] The anal tube is connected with the supporting column tube, and the anal tube joint tube and the supporting column tube are slidably sleeved. When the staff adjusts the position between the anal tube joint tube and the supporting column tube, they can be fixed by buckles to avoid slipping and displacement.

[0011] Fixation principle on the anal tube assembly:

[0012] (1) It is fixed with a silicone gel patch and adhered to the patient's anal area to prevent it from falling off and increase the patient's comfort.

[0013] (2) After the anal tube connector is inserted into the patient's anus, water can be injected into the air bag to expand it, thereby preventing the anal tube connector from slipping out of the anus.

[0014] By fixing at the above two locations, the anti-falling effect can be achieved to a greater extent, and there is no need to sew the anal canal to the perianal skin as in the prior art, thereby increasing the comfort.

[0015] Preferably, the side end of the anal canal is connected with an airbag water injection tube, and the airbag water injection tube is connected to the airbag.

[0016] How the airbag works:

[0017] When in use, sterile water is injected through a syringe to inflate the balloon, enhance the fixation effect of the anal tube, and reduce the incidence of related adverse events such as tube removal. When removing the tube, the sterile water injected in the early stage is drawn out to make the balloon deflate, and then the anal tube can be removed.

[0018] Preferably, the silicone gel fixation patch is provided with a PU waterproof protective layer on the side facing away from the anus. The PU waterproof protective layer can prevent the drainage fluid from leaking out and contaminating clothing or bedding.

[0019] Preferably, a sub-buckle is provided on the side wall of the anal tube joint tube, and a female buckle adapted to the sub-buckle is provided on the support column tube.

[0020] A buckle (female buckle) is provided inside the support column tube, which is used to mate and stick with the buckle (sub-buckle) to achieve a better effect of fixing the anal canal. At the same time, several sub-buckles are arranged according to the intervals of the canal, so that medical staff can choose the corresponding buckle for fixation according to the requirements of different cannulation depths.

[0021] Preferably, the end of the anal tube connector is wrapped with an impermeable film, the impermeable film is filled with paraffin oil, and a tear-off tape is provided at the connection between the impermeable film and the anal tube connector.

[0022] When in use, after tearing off the peeling tape, the anal tube soaked in paraffin oil can be directly inserted into the patient's body without the need to use paraffin oil cotton balls to lubricate the tube.

[0023] Preferably, a side hole is provided at the side end of the anal tube connector.

[0024] Preferably, the drainage device includes a drainage tube, a drainage tube interface, a negative pressure device and a drainage bag, the drainage tube and the drainage tube interface are connected, the negative pressure device and the drainage tube interface are connected, the free end of the drainage tube is provided with a drainage device interface, the free end of the anal tube is provided with an anal tube interface, and the drainage device interface and the anal tube interface are plugged together.

[0025] Preferably, the open end of the anal tube interface is provided with a cap.

[0026] Preferably, an exhaust port is provided at the upper end of the negative pressure device, and an exhaust port cap is provided on the exhaust port.

[0027] Preferably, the drainage bag is connected to a drainage tube, and a cut-off clamp switch is provided on the drainage tube. The setting of the cut-off clamp switch can prevent the patient's drainage fluid from dripping to the ground, and at the same time, it is convenient for staff to collect the drainage fluid as a sample for inspection.

[0028] Preferably, the anal tube connector is provided with scales.

[0029] When in use, the exhaust port cap 19 is placed on the exhaust port 20, and the negative pressure device 22 is manually compressed to cause the body fluid and gas to be introduced into the drainage bag 24 through its own deformation recovery.

[0030] Compared with the prior art, the beneficial effects of the utility model are:

[0031] This solution achieves three-dimensional anal tube fixation through innovative design of the anal tube, adding airbags, airbag water injection tubes, silicone gel fixation stickers, PU waterproof protective layers, support column tubes, and letter buckles, achieving the best tube stabilization effect. While improving the patient's treatment experience, it can also reduce the number of times medical staff change anal tubes and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
