Technical Field
[0001] The utility model relates to the technical field of medical catheters, in particular to an ultra-thin wall multi-lumen tube. Background Art
[0002] Medical catheters are tubular rubber products used for medical treatment. Multi-lumen catheters have two or more lumens and can perform multiple treatment operations simultaneously. Each chamber has a specific function, such as spraying medicine, draining fluids, or locating organs. Through different chamber operations, medical multi-lumen catheters can quickly and accurately perform inspections, diagnoses, and treatments, thereby improving treatment effectiveness and efficacy. In addition, multi-lumen catheters can also be equipped with auxiliary equipment such as latex balloons to seal or compress blood vessels and prevent blood reflux.
[0003] Currently, in a multi-lumen catheter for inserting into the human body, after the multi-lumen catheter is inserted into the patient's body, other medical tubes can be inserted into the inner cavity of the multi-lumen catheter. However, since the body, for example, the ureter, is relatively curved, when inserting other medical tubes into the inner cavity of the multi-lumen catheter, if the other medical tubes abut against the bent part of the multi-lumen catheter, a doctor is required to assist in manipulating the direction of the other medical tubes and then continue to deliver the tubes into the multi-lumen catheter, which makes delivery of the tubes less convenient.

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.
[0032] The embodiment of the present application discloses an ultra-thin-wall multi-lumen tube.
[0033] Reference Figure 1, an ultra-thin-wall multi-lumen tube, comprising a multi-lumen tube body 1, a main lumen 11 arranged along the length direction of the multi-lumen tube body 1, and a plurality of sub-lumen tubes 12 arranged along the length direction of the multi-lumen tube body 1, wherein the plurality of sub-lumen tubes 12 are arranged on the side wall of the main lumen 11, a medical tube 100 comprises a tube 101, and a slideway 121 for sliding of the tube 101 is arranged on the inner wall of the plurality of sub-lumen tubes 12, a slider 102 for sliding in the slideway 121 is arranged on the tube 101, and the slideway 121 is adapted to the slider 102.
[0034] When the doctor is performing a minimally invasive or non-invasive surgery, after inserting the multi-lumen tube body 1 into the patient's body, the doctor can manipulate the tube 101 to move to a position close to the auxiliary lumen 12, place the slider 102 inside the slide 121, and then continue to send the tube 101 into the auxiliary lumen 12. When the tube 101 moves, the slider 102 always slides inside the slide 121, thereby improving the stability and convenience of sending the tube 101 into the auxiliary lumen 12.
[0035] Reference Figure 2 Optionally, both sides of the pipe 101 in the length direction are rotatably connected with a sliding wheel 105 for rolling in a slideway 121. The sliding wheel 105 is adapted to the slideway 121. When the pipe 101 is inserted into the sub-lumen tube 12, the sliding wheel 105 can roll in the slideway 121, thereby improving the convenience of delivering the pipe 101 into the sub-lumen tube 12.
[0036] Reference Figure 1 The medical pipeline 100 includes a second pipeline 103 . A second slideway 111 for sliding the second pipeline 103 is provided on the main cavity 11 . A second slider 104 for sliding on the second slideway 111 is provided on the second pipeline 103 . The second slider 104 is adapted to the second slideway 111 .
[0037] The doctor can also manipulate the pipe 103 to move to a position close to the main cavity 11, place the slider 104 inside the slide 111, and then continue to insert the pipe 103 into the main cavity 11. When the pipe 103 moves, the slider 104 always slides inside the slide 111, thereby improving the stability and convenience of inserting the pipe 103 into the main cavity 11.
[0038] Reference Figure 2 Optionally, both sides of the pipe 103 in the length direction are rotatably connected with sliding wheels 106 for rolling in the slideway 111. The sliding wheels 106 are adapted to the slideway 111. When the pipe 103 is inserted into the main cavity 11, the sliding wheels 106 can roll in the slideway 111, thereby improving the convenience of delivering the pipe 103 into the main cavity 11.
[0039] The diameter of the main lumen 11 is greater than that of the secondary lumen 12 , so that when the tube is delivered into the multi-lumen tube body 1 , medical tubes 100 of different sizes can be delivered, thereby improving the applicability of the multi-lumen tube body 1 .
[0040] Reference Figure 1 and Figure 3 Optionally, several of the sub-lumen tubes 12 are arranged inside the multi-lumen tube body 1, and several of the sub-lumen tubes 12 are arranged circumferentially of the main lumen 11. If the multi-lumen tube body 1 is used as a carrier, when the user is given infusion treatment, the medicine can flow into the main lumen 11, and the liquid used to heat the main lumen 11 can be passed into the sub-lumen tubes 12, thereby achieving the effect of heating the medicine, thereby improving the comfort of the medicine being input into the user's body and reducing the occurrence of user discomfort caused by the medicine being too cold.
[0041] Reference Figure 4 Optionally, the plurality of sub-lumen tubes 12 are located on both sides of the main lumen tube 11 in the length direction. If the multi-lumen tube body 1 is used for minimally invasive surgery or non-invasive surgery, after the multi-lumen tube body 1 is inserted into the patient's body, a plurality of surgical instruments can be inserted into the interior of the multi-lumen tube from the main lumen tube 11 and the sub-lumen tube 12 respectively, thereby improving the applicability of the multi-lumen tube body 1.
[0042] Among them, the multi-lumen tube body 1 is made of PTFE material, which has good biocompatibility and can effectively reduce the occurrence of adverse reactions in patients. It also has high softness and elasticity and can better adapt to the curves and deformations of blood vessels and tissues, reducing trauma to patients.
[0043] The implementation principle of the ultra-thin-wall multi-lumen tube in the embodiment of the present application is: after the multi-lumen tube body 1 is inserted into the patient's body, the slider 102 can be inserted into the slideway 121, and then the tube can be sent into the secondary lumen 12, and then the slider 2 104 can be inserted into the slideway 2 111 to send the tube into the main lumen 11. When the medical tube 100 is sent into the multi-lumen tube body 1, it is relatively stable and convenient.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
