Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically the field of nasogastric tubes, and is a visual 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 tube placement typically employs blind insertion, endoscopy, or magnetic navigation technology. Traditional blind insertion requires highly experienced medical personnel, and the lack of observation during the procedure increases the risk of patient injury. Ultrasound confirmation of tube placement is also necessary, making the entire process quite difficult. Endoscopic placement requires sterilization of the endoscope before and after use, increasing the workload for medical staff and increasing the risk of cross-infection. Magnetic navigation technology is less widely used due to its high equipment cost and complex operation. Utility Model Content

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

[0005] Traditionally, nasogastric tubes are inserted blindly or with the aid of endoscopes and other auxiliary equipment. Blind insertion is not possible due to the lack of visualization, is difficult to perform, and is prone to causing injury to the patient. When using endoscopic equipment, the lens needs to extend beyond the tip of the nasogastric tube, which can also cause injury to the patient. Furthermore, it requires disinfection, which increases the risk of cross-infection. The procedure is relatively complex and requires highly experienced medical personnel to perform.

[0006] 2. Technical Solution:

[0007] To address the above issues, this utility model provides a visual nasogastric tube, comprising a tube body, one end of which is connected to a connector, and a visual probe disposed inside the other end of the tube body. The tube body is provided with a wire harness, one end of which is connected to the visual probe, and the other end of which is connected to an interface.

[0008] Furthermore, the wire harness passes through the tube and connects to the interface near the connector.

[0009] Furthermore, a base is provided on the tube body, the interface is located on the base, and the wire harness passing through the tube body is located inside the base.

[0010] Furthermore, the visible probe is provided with a spherical transparent cover, the spherical transparent cover is connected to the end of the tube body, and a covering layer is provided at the connection between the tube body and the spherical transparent cover.

[0011] Furthermore, the spherical transparent cover is made of transparent material, and the head end is spherical in shape, with the front end of the visual probe closely attached to the inside of the spherical transparent cover.

[0012] Furthermore, the covering layer provided at the connection between the spherical transparent outer cover and the front end of the tube body is fused together, and the surface is smooth.

[0013] Furthermore, the tube body is provided with a wire passage cavity, and the wire harness is disposed within the wire passage cavity.

[0014] Furthermore, the cavity of the tube body is not connected to the through-line cavity.

[0015] Furthermore, the wire harness, the tube body, and the wire passage are integrally formed.

[0016] Furthermore, the tube body and the covering layer are made of medical-grade polyurethane. A dustproof protective cap for the interface is provided on the base. The cavity of the tube body is coated with a water-repellent coating.

[0017] 3. Beneficial effects:

[0018] This invention, through improvements to the structure of the nasogastric tube, effectively solves the problem of lack of visualization during insertion of traditional nasogastric tubes. The spherical transparent outer shell at the front end prevents injury to the patient during insertion and alleviates discomfort. Because the nasogastric tube is for single use, it effectively avoids cross-infection during endoscope sterilization. This visual nasogastric tube has a simple design, is more convenient to operate, and is highly practical. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figure 1 As shown, a visual nasogastric tube includes a tube body 1, one end of which is connected to a connector 9, and a visual probe 2 is provided inside the other end of the tube body 1. The tube body 1 is provided with a wire harness 6, one end of which is connected to the visual probe 2, and the other end is connected to an interface 8.

[0024] The connector 9 is used to connect to the nutrient bag, and the nutrient bag delivers nutrient solution into the tube 1.

[0025] The interface 8 is used to connect to an external monitor for monitoring the real-time images from the visual probe 2.

[0026] In one embodiment, the wire harness 6 passes through the tube 1 and connects to the interface 8 near the connector 9.

[0027] In one embodiment, such as Figure 2 As shown, a base 7 is provided on the tube body 1, and the interface 8 is located on the base 7. The wire harness 6, which passes through the tube body 1, is located inside the base 7. The function of the base 7 is to fix the interface 8 and protect the wire harness 6 outside the tube body 1.

[0028] Medical staff connect connector 8 to an external monitor, then lubricate the visual probe 2 and the tip of tube 1. With the patient in a suitable position, tube 1 is slowly inserted into the patient's nasal cavity. During the insertion process, the position of tube 1 in the patient's stomach and intestines can be observed in real time through the monitor, so that medical staff can complete the tube placement work more quickly and effectively.

[0029] In one embodiment, the front end of the tube 1 is connected to a spherical transparent outer cover 3. The spherical transparent outer cover 4 is made of transparent material and has a spherical shape at the head end. The inside of the spherical outer cover needs to be in close contact with the front end of the visual probe 2 to ensure the clarity of the observed image. Since the front end is spherical, it is easier for hospital staff to operate, reduces the damage to the patient during catheter placement, and makes catheter placement safer.

[0030] In one embodiment, a covering layer 4 is provided at the connection between the tube body 1 and the spherical transparent outer cover 3 to ensure the smoothness of the connection, facilitate the operation of medical staff, and reduce the discomfort of patients.

[0031] In one embodiment, the main cavity of the tube body 1 is not connected to the wire passage cavity 5, and no liquid will enter the wire passage cavity 5, thus avoiding contact between the wire harness 6 and the liquid.

[0032] In one embodiment, the wire harness 6 is integrally formed with the tube body 1 and the wire passage 5, which facilitates manufacturing.

[0033] This invention uses a visual probe 2 to visualize the position of the tube 1 in the patient's stomach and intestines. The spherical design at the tip reduces damage to the patient and facilitates operation by medical staff during the tube insertion process. It also reduces the equipment maintenance cost when using an endoscope to assist in tube insertion.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of protection of the claims of this application.
