Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically the field of nasogastric tubes, and is a disposable nasogastric tube. Background Technology

[0002] A nasogastric tube is a commonly used medical device, mainly composed of a tube body, connector, guide wire with connector, and bullet tip. It is mainly used to insert into the patient's nasal cavity or intestine through the mouth for gastrointestinal decompression or enteral nutrition perfusion.

[0003] Currently, traditional nasogastric tubes are typically inserted blindly or with the aid of an endoscope. During insertion, when entering the greater curvature and pylorus of the stomach, the front end of the traditional nasogastric tube has a certain rigidity. When blindly inserting or using an endoscope for bending and guidance, the bending angle is insufficient, the bending resistance is poor, and the force required to pull the endoscope wire is too great, which can easily damage the endoscope equipment and make the operation difficult. Utility Model Content

[0004] 1. The technical problem to be solved:

[0005] The nasogastric tube has poor bending resistance at the front end. When blindly inserting it or using an endoscope for bending and guidance, the front end of the tube is not easy to bend, the angle is too small, and it is easy to damage the endoscope equipment, making the operation difficult.

[0006] 2. Technical Solution:

[0007] To address the above problems, this utility model provides a disposable nasogastric tube, including a tube body, one end of which is connected to a connector, and the other end of the tube body has multiple upper grooves on its upper side and multiple lower grooves on its lower side.

[0008] Furthermore, a covering layer is provided outside or inside the tube, the covering layer covering all the upper and lower grooves.

[0009] Furthermore, the coating layer is fused together with the tube body, and the surface of the fusion joint is smooth.

[0010] Furthermore, the shape of the upper groove includes one or more combinations of circles, rectangles, and V-shapes, and the shape of the lower groove 3 includes one or more combinations of circles, rectangles, and V-shapes.

[0011] Furthermore, the upper and lower grooves are distributed sequentially and evenly on the upper and lower sides of the tube body.

[0012] Furthermore, the tube body and the covering layer are made of medical-grade polyurethane material.

[0013] Furthermore, the connector is made of medical-grade ABS material.

[0014] Furthermore, the inner cavity of the tube is coated with a water-based coating.

[0015] Furthermore, when using endoscopic equipment, the endoscope is inserted into the tube 1 through connector 5, with the curved part of the endoscope located in the covering layer of the tube.

[0016] 3. Beneficial effects:

[0017] This invention optimizes and improves the structure of the nasogastric tube, effectively enhancing its bending resistance and mitigating the inconvenience and equipment damage associated with blind insertion or placement using endoscopes and other auxiliary equipment. This makes the nasogastric tube more convenient and reliable in actual operation. Attached Figure Description

[0019] Explanation of reference numerals in the attached drawings: 1. Pipe body; 2. Upper groove; 3. Lower groove; 4. Covering layer; 5. Joint. Detailed Implementation

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a disposable nasogastric tube structure includes a tube body 1, an upper side groove 2, a lower side groove 3, a cover 4, and a connector 5.

[0022] One end of the tube 1 is connected to the connector 5. The connector is used to connect an endoscope.

[0023] The other end of the tube 1 has multiple upper grooves 2 on its upper side and multiple lower grooves 3 on its lower side. The side grooves at the end of the tube 1 improve its bending resistance.

[0024] A covering layer 4 is provided on the outside or inside of the pipe body 1, covering all the upper grooves 2 and lower grooves 3. The covering layer ensures the tensile strength of the grooved parts of the pipe body and prevents pipe bending.

[0025] In one embodiment, the covering layer 4 is fused together with the tube body 1, and the surface of the fusion joint is smooth.

[0026] In one embodiment, the shape of the upper groove includes one or more combinations of circles, rectangles, and V-shapes, and the shape of the lower groove includes one or more combinations of circles, rectangles, and V-shapes.

[0027] In one embodiment, for better tensile strength, the upper groove 2 and the lower groove 3 are distributed sequentially and evenly on the upper and lower sides of the pipe body 1. Let the distance L1 between the upper groove 2 and the adjacent lower groove 3 be, specifically arranged as follows: the distance between the first upper groove and the first lower groove is L1, the distance between the first upper groove and the second upper groove is 2 L1, the distance between the first lower groove and the second upper groove is L1, the distance between the first lower groove and the second lower groove is 2 L1, and so on.

[0028] In one embodiment, the tube body 1 and the covering layer 4 are made of medical-grade polyurethane. The connector 5 is made of medical-grade ABS.

[0029] In one embodiment, when endoscopic assistance is used, the endoscope is inserted into the tube 1 via connector 5, with the curved portion of the endoscope located within the covering layer 4 of the tube 1. This configuration reduces the likelihood of damage or failure when the endoscope is used for curved guidance of the nasogastric tube, lowers equipment maintenance costs when using endoscope-assisted intubation, facilitates the operation of medical personnel during intubation, and reduces discomfort for patients caused by the rigid tip of the tube during intubation.

[0030] The usage process of this utility model is as follows: First, medical staff lubricate the end of the tube 1. The patient is in a suitable position, and the nasogastric tube is slowly inserted from the nasal cavity to the throat. The patient is instructed to swallow. If an endoscope is used, the endoscope is inserted into the tube 1 through the connector 5. The curved part of the endoscope is in the covering layer 4 of the tube 1.

[0031] Insert the nasogastric tube to the required length. During the insertion process, the tube body 1 is placed in the patient's stomach and intestines by rotating the tube body 1. If endoscopic equipment is used for assistance, the endoscope handle is adjusted to bend the tube.

[0032] The upper and lower side grooves and the covering layer 4 on the tube body 1 make the end of the tube body 1 more resistant to bending and less prone to breakage. This makes it easier for medical staff to adjust the end of the tube body 1, allowing them to place the tube body 1 into the patient's stomach and intestines more easily and quickly.
