Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a novel nasoenteric tube. Background Technology

[0002] A nasoenteric tube is a medical device that inserts a feeding tube through the nasal cavity into the intestine. It provides nutrients directly to the patient through the feeding tube, maintains intestinal integrity, reduces bacterial translocation, and lowers energy consumption and metabolic levels.

[0003] To locate the nasoenteric tube, doctors usually insert an endoscope into the abdominal cavity. However, because the nasoenteric tube is relatively thin, it can be difficult to see clearly when it passes through the endoscope's field of vision. This makes it impossible for doctors to accurately determine whether the nasoenteric tube has been correctly inserted into the intestine and whether the insertion depth is appropriate, requiring repeated adjustments, increasing the difficulty and time of the operation, and increasing patient discomfort and safety risks.

[0004] Although patent application CN201920578473.8 discloses a nasoenteric tube device with optical fiber, including a nasoenteric tube, a guide wire, a guide wire connecting handle, and a light-emitting device, wherein the guide wire is inserted into the nasoenteric tube; the guide wire connecting handle is located at one end of the guide wire; the light-emitting device includes a light-emitting body, a light-emitting connector, and a light-emitting guide wire, the light-emitting body contains a power source for providing power to the light-emitting device; the light-emitting connector is located at one end of the light-emitting body for docking with the guide wire connecting handle; the light-emitting guide wire is attached to the guide wire; and the light-emitting guide wire is inserted into the nasoenteric tube, with one end electrically connected to the guide wire connecting handle, the following technical problem still exists: because the light-emitting guide wire is attached along the entire guide wire, the entire guide wire emits light, making it difficult for doctors to judge whether the insertion depth of the nasoenteric tube is appropriate by changes in light intensity, and thus failing to provide accurate depth positioning information.

[0005] In view of the above, this utility model is hereby proposed. Utility Model Content

[0006] The purpose of this invention is to provide a novel nasoenteric tube to address the design flaws of existing nasoenteric tubes. In these tubes, the luminescent guide wire is attached along the entire guide wire, causing the entire guide wire to emit light. This makes it difficult for doctors to determine the appropriate insertion depth of the nasoenteric tube based on changes in light intensity, thus failing to provide accurate depth positioning information. The various technical effects of the preferred solutions provided by this invention are detailed below.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] This utility model provides a novel nasoenteric tube, comprising a guidewire and a light source assembly. The light source assembly includes a first light-emitting element, a second light-emitting element, a wire, and a control switch. The first light-emitting element and the second light-emitting element are respectively disposed on the wire, and the wire is electrically connected to the control switch. The first light-emitting element is located at the front end of the guidewire, and the distance between the second light-emitting element and the first light-emitting element is 10cm-30cm, with the second light-emitting element exposed outside the guidewire. The guidewire is wound around and covers the wire located inside the feeding tube.

[0009] Preferably, the guide wire is spirally coiled along the axial direction of the wire.

[0010] Preferably, the first light-emitting element and the second light-emitting element emit different colors.

[0011] Preferably, the distance between the second light-emitting element and the first light-emitting element is 20cm.

[0012] Preferably, the device further includes a feeding tube, the front of which has several through holes, the rear end of which has a first connector, and the rear end of which has a second connector, wherein the first connector and the second connector are inserted into each other.

[0013] Preferably, the front end of the feeding tube is an arc surface, forming a protective head.

[0014] Preferably, the device further includes a battery compartment, the wire extends to the outside of the second connector and is electrically connected to the battery compartment, and the control switch is disposed on the battery compartment and electrically connected to the battery compartment.

[0015] Preferably, the inner diameter of the feeding tube is 3.5 mm, the diameter of the guide wire is 0.8 mm, the diameter of the wire is 0.5 mm, and the diameters of the first light-emitting element and the second light-emitting element are 1 mm.

[0016] The preferred technical solution of this utility model can also produce at least the following technical effects:

[0017] This invention effectively avoids the design flaws of existing nasoenteric tubes, where the luminescent guidewire is attached along the entire guide wire, causing the entire guide wire to emit light. This makes it difficult for doctors to judge the appropriate insertion depth of the nasoenteric tube by changes in light intensity, thus failing to provide accurate depth positioning information. This invention provides a novel nasoenteric tube, including a guidewire and a light source assembly. The light source assembly includes a first light-emitting element, a second light-emitting element, a wire, and a control switch. The first and second light-emitting elements are respectively disposed on the wire, and the wire is electrically connected to the control switch. The first light-emitting element is located at the front end of the guidewire, and the distance between the second and first light-emitting elements is 10cm-30cm, with the second light-emitting element exposed outside the guidewire. The guidewire is wrapped around the wire located inside the feeding tube. The first light-emitting element at the front end of the guidewire serves as a visual marker for the front position of the feeding tube. The second light-emitting element, disposed on the guidewire and spaced 10cm-30cm from the first light-emitting element, serves as a visual marker for the preset insertion depth of the feeding tube. A guidewire is wrapped around the wire inside the feeding tube to prevent it from interfering with the normal insertion of the tube, while ensuring the proper functioning of both the first and second light-emitting elements. When the feeding tube is inserted into the intestine, the doctor can clearly observe the illuminated first light-emitting element through the endoscope to confirm that the tip of the feeding tube has correctly entered the intestine. As the feeding tube continues to be inserted, when the illuminated second light-emitting element is seen through the endoscope, it can be determined that the feeding tube has been correctly inserted to the preset depth in the intestine. This provides stable and reliable visual support for the doctor's operation, allowing for more accurate determination of the tip position and insertion depth of the feeding tube.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] like Figures 1-2 As shown, this utility model provides a novel nasoenteric tube, including a guide wire 5 and a light source assembly. The light source assembly includes a first light-emitting element 1, a second light-emitting element 2, a wire 3, and a control switch 4. The first light-emitting element 1 and the second light-emitting element 2 are respectively disposed on the wire 3, and the wire 3 is electrically connected to the control switch 4. The first light-emitting element 1 is located at the front end of the guide wire 5, and the distance between the second light-emitting element 2 and the first light-emitting element 1 is 10cm-30cm, and the second light-emitting element 2 is exposed outside the guide wire 5. The guide wire 5 is wrapped around and covered by the wire 3 located inside the feeding tube 6.

[0025] The first luminous element 1 is located at the tip of the guidewire 5, serving as a visual marker for the position of the feeding tube 6. The second luminous element 2 is located on the guidewire 5, with a distance of 10cm-30cm between it and the first luminous element 1, serving as a visual marker for the predetermined insertion depth of the feeding tube 6. When the feeding tube 6 is inserted into the intestine, the doctor can directly and clearly observe the lit first luminous element 1 through an endoscope to confirm that the tip of the feeding tube 6 has correctly entered the intestine. As the feeding tube 6 continues to be inserted, when the lit second luminous element 2 is seen through the endoscope, it can be determined that the feeding tube 6 has been correctly inserted to the predetermined depth in the intestine, providing stable and reliable visual support for the doctor's operation and enabling more accurate determination of the tip position and insertion depth of the feeding tube 6.

[0026] The guide wire 5 is wrapped around the wire 3 located inside the feeding tube 6, forming a tight connection and guiding the insertion of the feeding tube 6. At the same time, the first light-emitting element 1 and the second light-emitting element 2 are exposed outside the guide wire 5, which will not interfere with the normal insertion of the feeding tube 6. Meanwhile, the first light-emitting element 1 and the second light-emitting element 2 can work normally, providing intuitive and clear visual guidance for the doctor's operation.

[0027] The wire 3 is used to transmit electrical energy to the first light-emitting element 1 and the second light-emitting element 2, enabling them to light up. The wire 3 is electrically connected to the control switch 4, which allows the doctor to conveniently control the lighting and extinguishing of the first light-emitting element 1 and the second light-emitting element 2.

[0028] As an alternative implementation, the guide wire 5 is spirally coiled along the axial direction of the wire 3.

[0029] This design increases the flexibility of guidewire 5, making it easier for it to adapt to the intestines.

[0030] As an optional implementation, the first light-emitting element 1 and the second light-emitting element 2 emit different colors, which is configured to provide doctors with a more intuitive visual distinction.

[0031] Furthermore, the first light-emitting element 1 and the second light-emitting element 2 include LED lights, which have the advantages of small size and low power consumption.

[0032] As an optional implementation, the distance between the second light-emitting element 2 and the first light-emitting element 1 is 20cm.

[0033] As an optional implementation, it also includes a feeding tube 6, the front of which has a plurality of through holes 62, the rear end of which is provided with a first connector 63, and the rear end of the guide wire 5 is provided with a second connector 51, the first connector 63 and the second connector 51 being inserted into each other.

[0034] Furthermore, through holes 62 are evenly arranged at the front of the feeding tube 6 for the delivery of nutrient solution.

[0035] It should be noted that the assembly of the guide wire 5 and the feeding tube 6 by inserting and mating the first connector 63 and the second connector 51 is existing technology and will not be described in detail here.

[0036] As an optional implementation, the front end of the feeding tube 6 is an arc surface, forming a protective head 61.

[0037] This design reduces stimulation and damage to the nasal cavity and intestines during insertion.

[0038] As an optional implementation, a battery box 7 is also included, with a wire 3 extending to the outside of the second connector 51 and electrically connected to the battery box 7, and a control switch 4 disposed on the battery box 7 and electrically connected to the battery box 7.

[0039] Furthermore, the battery box 7 and the control switch 4 are exposed outside the second connector 51.

[0040] The function of battery box 7 is to provide power to the light source assembly.

[0041] The control switch 4 is located on the battery box 7, which makes it easier for doctors to control the lighting and extinguishing of the first light-emitting element 1 and the second light-emitting element 2, thus improving the ease of operation.

[0042] It should be noted that the specific circuit connection relationship between the first light-emitting element 1, the second light-emitting element 2, the wire 3, the battery box 7 and the control switch 4 is existing technology and will not be elaborated here.

[0043] As an optional implementation, the inner diameter of the feeding tube 6 is 3.5 mm, the diameter of the guide wire 5 is 0.8 mm, the diameter of the wire 3 is 0.5 mm, and the diameters of the first light-emitting element 1 and the second light-emitting element 2 are 1 mm.

[0044] This configuration allows the first light-emitting element 1 and the second light-emitting element 2 to be exposed on the guide wire 5 when the guide wire 5 spirals around the wire 3 along the axial direction of the wire 3. At the same time, it does not interfere with the insertion function of the feeding tube 6.

[0045] Due to the specifications and selection of the first light-emitting element 1, the second light-emitting element 2, and the wire 3, the required power transmission is relatively small, and the specifications of the battery box 7 can be designed to be more compact to reduce the overall weight while meeting the requirements of low power consumption.

[0046] It should be noted that the first light-emitting element 1, the second light-emitting element 2, the wire 3, and the guide wire 5 are all finished products using existing technology, which will not be elaborated on here.

[0047] It is understood that the same or similar parts in the above embodiments can be referred to each other, and the contents not described in detail in some embodiments can be referred to the same or similar contents in other embodiments.
