[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] The utility model aims to solve the problems in the prior art that when a patient needs both nasogastric endoscopy and nasogastric feeding, the nasogastric endoscopy and nasogastric tube need to be inserted into the patient's stomach in sequence, which aggravates the patient's physical and psychological discomfort, and the existing nasogastric tube has various defects by increasing the hardness or using soluble substances for traction. Figure 1-2 As shown, the following technical solution is provided: a small intestinal nutrition tube suitable for nasal gastroscope insertion, comprising a first pipeline 11 and a second pipeline 12, the second end of the first pipeline 11 is detachably connected to the first end of the second pipeline 12, the second end of the second pipeline 12 is connected to an external medical device, the inner diameter of the first pipeline 11 is not less than the size of the nasal gastroscope to be inserted, and a protrusion 111 for clamping the end of the nasal gastroscope to be inserted is provided on the inner wall of the first pipeline 11 near its first end, and a plurality of through holes 112 are provided on the side wall of the first pipeline 11 near the first end. By providing the protrusion 111, the front end of the nasal gastroscope can be clamped with the first pipeline 11, so that the nasal gastroscope and the first pipeline 11 will not be separated, thereby achieving the purpose of bringing the nutrition tube to a specified position in the body through the nasal gastroscope, and at the same time, the diameter of the first pipeline 11 is large and not easy to be blocked.

[0023] The exemplary method of using the small intestinal nutrition tube suitable for nasogastric insertion provided in this embodiment is to first insert the nasogastric endoscope into the first tube 11 and contact it with the raised portion 111, and then insert the first tube 11 with the built-in nasogastric endoscope into the patient's small intestine or stomach through the patient's nasal cavity. After completing the required endoscopic examination, the nasogastric endoscope is withdrawn, and then the first tube 11 and the second tube 12 are connected, and the second tube 12 is connected to an extracorporeal medical device, such as a negative pressure suction device or a syringe, to extract gastric juice or inject nutrient solution for the patient.

[0024] The improved structural design of the small intestinal nutrition tube suitable for nasogastric insertion provided in this embodiment can complete the nasogastric examination and nutrient solution injection of the patient through the same intubation operation, which can greatly reduce the patient's discomfort and shorten the treatment time. At the same time, with the help of the nasogastric traction, the nutrition tube can enter the patient's body more smoothly, and the intubation position can be observed in time through the nasogastric during the intubation process, effectively avoiding the misdiagnosis of the existing methods of observing bubbles, auscultating the sound of air passing through water, and the increase in medical costs caused by the X-ray verification method. This patent is particularly suitable for patients with unclear consciousness, inability to open their mouths, and difficulty in inserting ordinary gastroscopes and nutrition tubes after throat surgery, esophageal stenosis, esophageal tracheal fistula, etc. Compared with ordinary gastroscopes, the insertion reaction is small and easier to accept. Compared with ordinary nutrition tubes, the inner diameter is thicker and not easy to block. At the same time, the nasogastric scope is entered at one time, and the front end of the nutrition tube is equivalent to a transparent cap, and the lesions of the esophagus, gastric cavity, pylorus, duodenum, etc. can be observed under direct vision. The nutrition tube has a simple structure and is easy to use, which can greatly improve the patient's medical experience and reduce medical costs.

[0025] The size of the small intestinal nutrition tube provided in this embodiment can be determined as needed. For example, the diameter of both tubes is preferably slightly larger than the size of the naso-gastroscope to be inserted. For example, if the existing naso-gastroscope is 5.9mm, the diameter of the first pipeline 11 can be 6.2mm-8mm. The diameter of the second pipeline 12 can be the same as or slightly larger than the first pipeline 11. For example, in some examples, in order to better connect with the external device, the second end opening of the second pipeline 12 is larger than the first end opening. For example, the second pipeline 12 can be spliced ​​by two sections of pipelines with different diameters, so the diameter of the second pipeline 12 is abrupt. But in a preferred example, the diameter of the second pipeline 12 gradually increases from the first end to the second end. Therefore, the second pipeline 12 has a gradual diameter and will have a conical surface, which helps to improve the injection efficiency. The length of the first tube 11 is preferably greater than that of the second tube 12. Depending on the placement location, such as placement in the gastric cavity or the duodenal cavity, the length of the first tube 11 may be 50 cm-110 cm, and the length of the second tube 12 may be 20 cm-50 cm.

[0026] The detachable structure between the first pipeline 11 and the second pipeline 12 can be adjusted as needed, and can be connected by thread, by a screw, or by a plug. In a preferred example provided in the present application, the first pipeline 11 and the second pipeline 12 are connected by threaded matching. For example, the outer wall of the rear end of the first pipeline 11 is provided with an external thread 113 and the inner wall of the second pipeline 12 is provided with an internal thread 121. Figure 1 The figure shows the internal thread 121 of the second pipeline 12. When the second pipeline 12 is transparent, the internal thread 121 can be observed. The first pipeline 11 can be screwed into the second pipeline 12 to achieve the connection between the two.

[0027] In this embodiment, the protrusions 111 are convex points and are staggered around the same radial section of the inner wall of the first conduit 11. The front end of the nasogastric endoscope can be pre-engaged by the convex points. Specifically, the plurality of protrusions 111 are distributed in a three-point plane on the inner wall of the first conduit 11 (e.g. Figure 2 As shown), the nasal gastroscope can be clamped without affecting the field of view. The raised portion 111 can be one or both of spherical and cylindrical shapes, such as a rectangular column, a circular column, a conical column, etc., preferably a spherical column. The extended length of the raised portion 111 is preferably no more than one quarter of the diameter of the first pipeline 11, in order to clamp the nasal gastroscope, and its purpose is also to reduce the obstruction of the nasal gastroscope's observation field of view. The raised portion 111 and the first pipeline 11 are preferably integrally formed, for example, by a mold.

[0028] In this embodiment, the first pipeline 11 and the second pipeline 12 are preferably made of the same material, for example, both can be made of common rubber tubes, polyimide tubes, silicone tubes, etc. commonly used on the market. In this embodiment, the first pipeline 11 and the second pipeline 12 are preferably transparent flexible tubes, such as silicone tubes, especially the first pipeline 11 is preferably a transparent tube, which can increase the front observation field of the nasogastric endoscope and facilitate the observation of the position of the nasogastric endoscope and the nutrient solution in the first pipeline 11 and the second pipeline 12. For example, the first pipeline 11 is made of silicone tube, which is not only more conducive to processing, but also has good softness, which can effectively prevent the raised portion 111 from causing wear to the nasogastric endoscope.

[0029] In this embodiment, the second pipeline 12 is provided with a plug 122 that can be used to block the second end opening of the second pipeline 12. The plug 122 is fixedly connected to the outer tube wall of the second end of the second pipeline 12. The plug 122 can block the second end of the second pipeline 12 when the second pipeline 12 is not in use. The plug 122 and the tube wall of the second pipeline 12 are preferably integrally formed. The plug 122 and the rear end opening of the second pipeline 12 can be threaded or interference fit. The plug 122 can be provided with an outer edge surface and a handle for easy insertion and removal. The plug 122 can be provided to block the nutrition tube when not in use to prevent gastric fluid from reflux.

[0030] The nutrition tube of this embodiment can be used in a variety of medical occasions, so there are also a variety of choices for the in vitro medical device connected thereto. For example, in some examples, the in vitro medical device is a negative pressure suction device, and after the nutrition tube is connected, medical operations such as extracting gastric juice from the patient can be performed. In other examples, the in vitro medical device is a syringe, and after the nutrition tube is connected, nutrient solution or medicine can be injected into the patient.

[0031] In this embodiment, if Figure 1As shown, the through holes 112 are evenly arranged along the axial direction of the side wall of the front end of the first pipeline 11, so that the nutrient solution can be discharged at the front end, which can increase the feeding efficiency and reduce the probability of blockage. The position of the through hole 112 can be flexibly selected, but in a preferred example, the through hole 112 is located on the side close to the front end of the protrusion 111. That is, the through hole 112 and the protrusion 111 are not on the same circumferential surface to prevent interference between the two and avoid deformation of the nutrient tube due to excessive local structures.

[0032] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0033] In the description of the present invention, “plurality” means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation" and the like should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
