[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, other embodiments obtained by ordinary technicians in the field without creative work are all within the scope of protection of the utility model.

[0034] See also Figure 1 , Figure 2 and Figure 3In one embodiment of the utility model, a fistula tube assembly is disclosed, including a fistula tube 100, wherein the fistula tube 100 includes a first end for extending into the digestive tract and a second end for extending out of the abdominal wall, and a flow passage is provided inside the fistula tube 100; a transfer tube 200, connected to the fistula tube 100; the hardness of the transfer tube 200 is greater than the hardness of the fistula tube 100; a shunt tube assembly 300, wherein at least two injection ports and at least one liquid outlet are provided on the shunt tube assembly 300, and the injection port is used for taking in liquid; the liquid outlet is connected to an end of the transfer tube 200 away from the fistula tube 100; and a cap 400, which is detachably arranged on the injection port.

[0035] In this embodiment, the hardness of the adapter tube 200 is greater than that of the fistula tube 100 , so that the adapter tube 200 can be inserted into the fistula tube 100 and is less likely to deform than the fistula tube 100 .

[0036] Specifically, one end of the fistula tube 100 is arranged in the digestive tract, and the other end extends to the outside of the abdominal wall. A flow path is arranged inside the fistula tube 100. The end of the fistula tube 100 located outside the body is connected to a transfer tube 200, and the end of the transfer tube 200 away from the fistula tube 100 is connected to a shunt tube assembly 300. When it is necessary to inject liquid medicine or nutrient solution into the patient's digestive tract, the cap 400 is opened, and after aligning the syringe or feeding device filled with liquid medicine with the injection port, the liquid medicine in the syringe or the feeding device is pushed into the shunt tube assembly 300. The injected liquid medicine passes through the shunt tube assembly 300, the transfer tube 200 and the fistula tube 100 in turn, and finally enters the digestive tract to achieve the intake of liquid medicine. After the intake of liquid medicine is completed, the cap 400 is covered to close the flow path of the fistula tube 100.

[0037] It should be noted that the adapter tube 200 in this embodiment is detachably connected to the main tube 310. After the injection of the liquid medicine is completed, the shunt tube assembly 300 can also be removed, and the cap 400 can be directly covered on the end of the adapter tube 200 away from the fistula tube 100 to close the flow path of the fistula tube 100. When the liquid medicine does not need to be injected, the shunt tube assembly 300 can be removed, which effectively simplifies the structure of the fistula tube assembly and makes it more convenient to use.

[0038] In this embodiment, a transfer tube 200 is provided on the fistula tube 100 to facilitate the connection of the fistula tube 100 with an external feeder or syringe, a cap 400 is provided to close the passage, and a diversion tube assembly 300 with at least two injection ports is provided to enable the fistula tube 100 to be connected to a variety of feeders or syringes to inject different liquids, and the operation is simple and convenient.

[0039] See also Figure 4The diversion tube assembly 300 includes: a main tube 310, which is connected to the end of the transfer tube 200 away from the fistula tube 100; at least two branch tubes, one end of which is rotatably connected to the end of the main tube 310 away from the fistula tube 100, and the other end is provided with the injection port.

[0040] In this embodiment, the injection port includes a first injection port for connecting to an external small-caliber intake device and a second injection port for connecting to an external large-caliber intake device, and the caliber of the first injection port is smaller than the caliber of the second injection port.

[0041] When the caliber of the first injection port is smaller than that of the second injection port, it is used to connect with different intake devices. For example, the opening of the first injection port is smaller and can be used to connect with a syringe, and the second injection port is set larger than the first injection port and is used to connect with a feeder.

[0042] This embodiment can better adapt to intake tools of different sizes by setting the first injection port and the second injection port to different sizes, thereby improving the applicability of the fistula tube assembly.

[0043] See also Figure 4 In this embodiment, two branch pipes are provided, including a first branch pipe 320 and a second branch pipe 330. The first branch pipe 320 includes two interconnected pipe sections, a certain angle is formed between the two pipe sections, one of which is rotatably connected to the main pipe 310, and the other pipe section is provided with the first injection port. The second branch pipe 330 includes two interconnected pipe sections, a certain angle is formed between the two pipe sections, one of which is rotatably connected to the main pipe 310, and the other pipe section is provided with the second injection port.

[0044] The first branch pipe 320 is configured as two pipe sections forming a certain angle, so that the first injection port is away from the second branch pipe 330, which can effectively increase the operating space of the first injection port; it is convenient for medical staff to operate. Similarly, the structure of the second branch pipe 330 is similar to that of the first branch pipe 320, which also effectively increases the operating space of the second injection port. By rotating the first branch pipe 320 or the second branch pipe 330, the horizontal direction of the first injection port and the second injection port can be adjusted according to the operation needs.

[0045] When two liquids need to be injected at the same time, one liquid can be injected from the first injection port, and the other liquid can be injected from the second injection port, which effectively improves the injection efficiency. It should be emphasized that the first branch pipe 320 is rotatably connected to the main pipe 310, and the second branch pipe 330 is rotatably connected to the main pipe 310. When the first branch pipe 320 and the second branch pipe 330 are injected with liquid at the same time, the first branch pipe 320 can be rotated so that the first injection port on the first branch pipe 320 is away from the second branch pipe 330, so as to avoid interference between the two syringes due to being too close, which is more convenient for medical staff to operate.

[0046] In this embodiment, the main pipe 310 includes a liquid outlet end for connecting to the transfer pipe 200 and a liquid inlet end for connecting to the at least two branch pipes. The diameter of the main pipe 310 gradually decreases from the liquid inlet end toward the liquid outlet end. A cavity is provided inside the main pipe 310. The liquid outlet end of the main pipe 310 is provided with the liquid outlet. The end of the transfer pipe 200 away from the fistula tube 100 is connected to the liquid outlet. The liquid inlet end of the main pipe 310 is provided with at least two branch holes, and the at least two branch pipes can be rotatably arranged in the at least two branch holes respectively.

[0047] In this embodiment, the diameter of the main pipe 310 gradually decreases from the liquid inlet end toward the liquid outlet end, so that the cavity of the main pipe 310 forms a structure with a large inlet and a small outlet, which plays a role in draining the ingested liquid and improves the liquid intake efficiency.

[0048] See also Figure 5 The cap 400 includes: a shell 410, a connecting cavity and a mounting cavity are coaxially arranged in the shell 410, the opening of the connecting cavity is toward the rear end of the shell 410, and the opening of the mounting cavity is toward the head end of the shell 410, a connecting column 420 is coaxially arranged in the connecting cavity, and a through hole connecting the connecting cavity and the mounting cavity is provided in the connecting column 420; a rubber plug 430 is arranged in the mounting cavity for the needle tip of the infusion needle to be inserted.

[0049] Specifically, when it is necessary to take liquid into the injection port, the cap 400 can be opened, and then the liquid can be taken into the injection port, and the cap 400 can be covered after taking the liquid. It should be emphasized that since the rubber plug 430 is provided in the housing 410, the medical staff can directly insert the needle of the syringe into the rubber plug 430 and then enter the shunt tube assembly 300 through the through hole in the connecting column 420, which effectively simplifies the operation process and is more convenient to use.

[0050] In this embodiment, the cap 400 includes a first cap and a second cap. The size of the first cap matches the size of the opening of the first injection port, and the size of the second cap matches the size of the opening of the second injection port.

[0051] In this embodiment, the size of the end opening of the adapter tube 200 away from the end of the fistula tube 100 is consistent with the size of the opening of the injection port. For example, the size of the end opening of the adapter tube 200 away from the end of the fistula tube 100 is consistent with the size of the opening of the first injection port, so that the first cap can be covered on the end opening. Alternatively, the size of the end opening of the adapter tube 200 away from the end of the fistula tube 100 is consistent with the size of the opening of the second injection port, so that the second cap can be covered on the end opening.

[0052] Specifically, when the shunt tube assembly is not needed, the shunt tube assembly 300 is removed, and the first cap is covered on the end of the adapter tube 200 away from the fistula tube 100 to close the flow path of the fistula tube 100. By setting the opening size of the end opening of the adapter tube 200 away from the fistula tube 100 to be consistent with the opening size of the first injection port, the versatility of the first cap 400 is improved, and the structure of the fistula tube assembly is effectively simplified.

[0053] In this embodiment, the outer surface of the housing 410 at one end close to the opening of the connecting cavity is provided with anti-skid patterns, which effectively prevents the medical staff from slipping during operation.

[0054] In this embodiment, the cap 400 further includes a flexible connection portion, one end of which is connected to the flow dividing pipe assembly 300 , and the other end of which is detachably connected to the housing 410 .

[0055] When the cap 400 is removed, the cap 400 is hung on the shunt tube assembly 300 through the soft connecting part to prevent the cap 400 from being lost. Furthermore, the cap 400 is detachably connected to the soft connecting plate. When the shunt tube assembly 300 is not needed, the cap 400 hung on the shunt tube assembly 300 is removed and covered on the end of the connecting tube away from the fistula tube 100 to seal the flow path in the fistula tube 100. The structure is simple and easy to use.

[0056] In this embodiment, the adapter tube 200 includes a tube body and an anti-slip annular protrusion. The tube body is cylindrical and has a through flow channel inside. The anti-slip annular protrusion is arranged on the outer surface of one end of the tube body close to the fistula tube 100, and the annular protrusion is inclined in a direction away from the fistula tube 100.

[0057] Specifically, the fistula tube 100 is sleeved on the cylindrical tube body, the flow channel inside the fistula tube 100 is connected with the flow channel inside the tube body, the annular protrusion is inclined in the direction away from the fistula tube 100, and plays a guiding role for the fistula tube 100, so that the fistula tube 100 can be more easily inserted into the tube body, and the annular protrusion forms a barb structure facing away from the fistula tube 100, which effectively prevents the fistula tube 100 from falling off the tube body and improves the connection stability of the connecting tube.

[0058] In summary, the fistula tube assembly of the present embodiment includes a fistula tube 100, an adapter tube 200, a shunt tube assembly 300 and a cap 400. A flow passage is provided inside the fistula tube 100 for supplying the ingested liquid from outside the patient's body to the patient's digestive tract; the adapter tube 200 can be inserted into the fistula tube 100 and is less likely to deform than the fistula tube 100; one end of the shunt tube assembly 300 is connected to the adapter tube 200, and the other end is provided with at least two injection ports for ingesting liquid; the cap 400 is connected to the injection port for controlling the opening and closing of the injection port. The utility model provides an adapter tube 200 on the fistula tube 100 to facilitate the connection of the fistula tube 100 with an external medical appliance, provides a cap 400 to facilitate the control of the closure of the flow passage of the fistula tube 100, and provides a shunt tube assembly 300 on the adapter tube 200. The shunt tube assembly 300 is provided with at least two injection ports, so that the fistula tube 100 can be connected to multiple feeders or syringes at the same time to achieve the injection of different liquids, and the operation is simple and convenient.
