Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a drainage tube with a support function. Background Technology
[0002] Stent placement refers to the implantation of a stent into a lumen (such as the trachea, bronchi, esophagus, intestines, ureter, blood vessels, etc.) to improve functional impairment caused by luminal narrowing. As a physical support, the stent can expand the narrowed area, restore the patency of the lumen, and thus relieve related symptoms. During the procedure, some procedures require the initial insertion of a drainage tube, followed by its removal and subsequent stent implantation. Furthermore, the stent is not permanently implanted but rather for a short period. In cases where the stent is made of non-degradable material, it must be removed later, and stent removal is relatively difficult. In some surgeries, after stent implantation, a drainage tube is also needed to facilitate wound healing at the stent site and prevent the introduction or removal of substances that could affect the tissue at the stent site. The simultaneous placement of the stent and drainage tube can cause inconvenience to the patient. Utility Model Content
[0003] In view of the above problems, this utility model is proposed to provide a drainage tube with a supporting function that overcomes or at least partially solves the above problems, and can provide support and expansion while draining, thereby reducing the number of implantable devices.

[0005] The tube body has a support section, which is configured to support human or animal tissue that is in contact with the outer peripheral wall of the support section.
[0006] Optionally, the tube body further includes a first drainage section connected to one end of the support section, and / or a second drainage section connected to the other end of the support section;
[0007] The drainage hole is disposed on the first drainage section, and / or the drainage hole is disposed on the second drainage section.
[0008] Optionally, the outer diameter of the support section is 14F to 24F.
[0009] Optionally, the outer diameter of some or all of the first drainage section is equal to the outer diameter of the support section; the outer diameter of some or all of the second drainage section is equal to the outer diameter of the support section; or, the outer diameter of the first drainage section is smaller than the outer diameter of the support section, and the outer diameter of the second drainage section is smaller than the outer diameter of the support section.
[0010] The drainage channel includes a first segment corresponding to the support segment, a second segment corresponding to the first drainage segment, and a third segment corresponding to the second drainage segment, wherein the second segment is less than or equal to the first segment, and the third segment is less than or equal to the second segment.
[0011] Optionally, the material of the first drainage section is the same as the material of the support section, and the material of the second drainage section is the same as the material of the support section.

[0030] Figure 1 This is a schematic structural diagram of a drainage tube with a supporting function according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 4 This utility model provides a drainage tube with a supporting function, including a tube body with a drainage channel 29 inside the tube body and a drainage hole 31 communicating with the drainage channel 29 on the tube body. The tube body is used for implantation in the body, with one end of the tube body outside the body. Substances can be injected into the body or drained from the body through the drainage channel 29 and drainage hole 31. The tube body has a supporting section 21, which is configured to support human or animal tissue in contact with its outer peripheral wall. The supporting section 21 has a certain supporting function; that is, when the supporting section 21 is compressed, the compression is relatively small, or in other words, it is basically not compressed, or it still has a sufficient outer diameter after compression to meet the expansion requirements of narrow sections within the tissue.
[0031] In this embodiment of the invention, the drainage tube has a support section 21, which is installed in the tissue requiring expansion. Even when compressed, the support section 21 can still meet the expansion requirements of the narrowed segment within the tissue, meaning it functions as a support stent, thus eliminating the need for stent implantation. In other words, the support section 21 acts as a support stent, allowing for the direct implantation of a drainage tube for non-permanent stents or short-term stent placement. This facilitates drainage, allowing for the introduction or removal of substances from the patient's body without affecting the tissue at the support section 21. For narrowed segments requiring expansion without external drainage, the drainage tube with this support function can also be implanted. At least a portion of the drainage tube is outside the patient's body, facilitating removal with minimal damage.
[0032] In some embodiments of this invention, the tube body further includes a first drainage section 22 connected to one end of the support section 21. The first drainage section 22 may be located at the end of the tube body inside the patient's body. The support capacity of the first drainage section 22 may be equal to or weaker than that of the support section 21, facilitating the extension of the first drainage section 22 within the body.
[0033] In some other embodiments of this utility model, the tube body further includes a second drainage section 23 connected to the other end of the support section 21. The support capacity of the second drainage section 23 may be equal to or weaker than that of the support section 21, which facilitates the extension of the second drainage section 23 within the body and its bending outside the body.
[0034] In some preferred embodiments of this utility model, the tube body further includes a first drainage section 22 connected to one end of the support section 21, and a second drainage section 23 connected to the other end of the support section 21. That is, the tube body has a support section 21, a first drainage section 22, and a second drainage section 23.
[0035] In some embodiments of this utility model, there is one support section 21. In some preferred embodiments of this utility model, there are multiple support sections 21, which are connected by connecting pipe sections. The support section 21 can be configured as one or more sections as needed. When the support capabilities of the first drainage section 22, the second drainage section 23, and the support section 21 are consistent, most or all of the entire pipe body has a support function, thus eliminating the need for multiple support sections 21. Of course, for better adaptability of the drainage pipe, one or more support sections can be set as needed.
[0036] In some embodiments of this utility model, the drainage hole 31 is disposed on the first drainage section 22, and / or the drainage hole 31 is disposed on the second drainage section 23. Of course, in some optional embodiments, the drainage hole 31 may also be disposed on the support section 21.
[0037] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the diameter of the drainage channel 29 is 1 / 8 to 5 / 8 of the outer diameter of the support section 21. This design allows the support section 21 to have a larger wall thickness, providing sufficient support without changing the material or existing drainage capacity. Of course, other suitable materials that meet both support capacity and human comfort can be used as needed.
[0038] For example, the outer diameter of the support section 21 is 14F to 24F. The inner diameter of the support section 21 can be 3F to 7F. Alternatively, the diameter of the drainage channel 29 can be 3F to 7F. F stands for inches. For example, the drainage tube is a urine drainage tube that can be used to dilate urethral strictures, which refer to narrowing of any part of the urethra, leading to difficulty urinating or urinary retention. This drainage tube allows for dilation of the urethral stricture while also enabling urination, and is easy to remove after dilation.
[0039] In some embodiments of this utility model, such as Figure 3 As shown, the outer diameter of some or all sections of the first drainage section 22 is equal to the outer diameter of the support section 21; the outer diameter of some or all sections of the second drainage section 23 is equal to the outer diameter of the support section 21. The drainage channel 29 includes a first section corresponding to the support section 21, a second section corresponding to the first drainage section 22, and a third section corresponding to the second drainage section, wherein the second section is less than or equal to the first section, and the third section is less than or equal to the second section. In this embodiment, the outer diameter of the support section 21 can be set to the maximum, and the remaining sections can be set to be consistent with the outer diameter of the support section 21 as needed, or adaptively tapered from the support section 21.
[0040] In other embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the outer diameter of the first drainage section 22 is smaller than the outer diameter of the support section 21, and the outer diameter of the second drainage section 23 is smaller than the outer diameter of the support section 21.
[0041] In some embodiments of this utility model, the material of the first drainage section 22 is the same as that of the support section 21, and the material of the second drainage section 23 is the same as that of the support section 21. The embodiments of this invention facilitate processing and improvement by varying the inner diameter, outer diameter, and material of each section, while also enabling the support section 21 and even the entire pipe to have a supporting function.
[0042] In some embodiments of this invention, the tube body is equipped with a guidewire for insertion under the guidance of the guidewire. The drainage tube with support function of this invention is equipped with a guidewire, which makes insertion easier. After the guidewire is inserted, the tube body can be inserted through the guidewire, which is convenient, quick, and causes minimal damage to the patient.
[0043] In some other embodiments of this invention, a balloon 27 is provided on the first drainage section 22, and the tube body also has an inlet channel or inlet tube 28, which communicates with the balloon 27. The balloon 27 can be inflated with air or water to prevent the tube body from dislodging from the patient's body. The inlet channel can be directly formed within the tube body, and the inlet channel and drainage channel 29 are independently configured. Alternatively, an inlet tube 28 can be provided, which passes through the drainage channel 29 of the tube body.
[0044] In some embodiments of this invention, the first drainage section 22 has a bent and extended anti-detachment section 32. The drainage tube may also include a control rope 24, one end of which is connected to the anti-detachment section 32 to control the anti-detachment section 32. The control rope 24 can control the shape of the anti-detachment section 32, thereby preventing the tube from falling off. Compared to the balloon 27, the structure of the drainage tube is simpler.
[0045] Furthermore, the drainage hole 31 is provided on the first drainage section 22, wherein at least a portion of the drainage hole 31 is provided on the bending anti-detachment section 32; or the end of the first drainage section 22 is an open end, so as to form the drainage hole 31.
[0046] In other embodiments of this utility model, such as Figure 4 As shown, the external end of the tube is equipped with an interface structure 25 and / or a switch structure. The external end of the tube is located on the outside of the patient's body, where the interface structure 25 can be connected for connecting a collection bag 26, or as an injection port for connecting to an injection device. When not in use, the switch structure closes the tube to prevent conduction. Both the interface structure 25 and the switch structure can be configured as needed.
[0047] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
