Description

Technical Field

[0001] The utility model relates to the technical field of nasogastric tube cleaning, in particular to an improved nasogastric tube flushing device. Background Art

[0002] Nasogastric feeding, also known as nasogastric tube placement or gastrointestinal decompression, is generally understood as a method of delivering nutrition or decompression through a tube from the nasal cavity to the stomach. Nasogastric feeding tubes are mainly suitable for patients who are in a coma, have lost or impaired swallowing reflexes, have undergone tracheotomy, or have undergone certain oral or pharyngeal surgeries and are unable or unsuitable to eat orally. Not only do these people need it, but with the increasing aging population in China, many elderly people have varying degrees of illnesses, such as dysphagia in the elderly, stroke, vegetative state, refusal to eat, etc., which can all be treated. Nasogastric feeding can provide enteral nutrition to the human body and prevent aspiration. Some patients will be discharged from the hospital with a nasogastric feeding tube, and the patients and their families need to perform the nasogastric feeding infusion operation by themselves, so a nasogastric feeding tube is needed. However, since the nasogastric feeding tube is relatively thin and the injected nutrient solution is relatively viscous, it is easy to cause blockage of the nasogastric feeding tube over time, especially the connector of the nasogastric feeding tube is more prone to blockage.

[0003] However, in the existing technology, the method of cleaning nasogastric tubes is mainly manual, which requires a lot of time and energy, especially when the nasogastric tubes need to be replaced frequently, which brings additional burden to the nursing staff. Since the nasogastric tubes are thin, it is difficult to clean the inside of the nasogastric tubes, and manual cleaning is difficult to achieve a complete cleaning effect. If the cleaning is not thorough, the residue may cause bacteria to grow, thereby increasing the risk of infection. Utility Model Content

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0023] Reference Figure 1-6 As shown, the embodiment of the present utility model provides an improved nasogastric tube flushing device, including a gun body 1, a housing 2 is fixedly connected to the right end of the gun body 1, a piston assembly 12 is provided inside the housing 2, a gun head assembly 9 is provided at the left end of the gun body 1, and the gun head assembly 9 includes a tapered cylinder 901, which is sleeved on the outside of the left end of the gun body 1, and a flushing valve 902 is fixedly connected to the left end of the tapered cylinder 901;

[0024] The setting of the flushing valve 902 allows the flushing liquid to enter the nasogastric tube at a relatively high flow rate during the flushing process, making the flushing more thorough. A sealing ring 903 is fixedly connected to the outer surface of the conical cylinder 901. The design of the conical cylinder 901 is convenient for inserting the nasogastric tube, and the sealing ring 903 on its surface can effectively prevent the leakage of the flushing liquid, thereby ensuring the closedness of the flushing. A filling pipe 7 is fixedly connected to the rear position of the upper middle part of the gun body 1, and a sealing cover 8 is threadedly connected to the filling pipe 7; limiting grooves 10 are provided on the upper and lower inner walls of the gun body 1, and a valve 11 is fixedly connected to the left end of the gun body 1; the valve 11 is closed when there is no force under normal circumstances, and forms a channel when subjected to external force to prevent the flushing liquid inside the gun body 1 from flowing out; the design of the above-mentioned gun body 1 is easy to hold and operate, so that medical staff can easily grasp and control it during use.

[0025] When the device is in use, first open the sealing cover 8 and inject flushing liquid into the gun body 1 through the filling pipe 7, and re-screw the sealing cover 8, then insert the conical cylinder 901 and the flushing valve 902 into the nasogastric tube, and the sealing ring 903 is deformed to seal the conical cylinder 901 and the nasogastric tube, then hold the handle 3 and use the finger to press the button 4 to control the servo motor 1207 to start, and the output end of the servo motor 1207 drives the driving gear 1208 to rotate, and drives the driven gear plate 1203 to rotate through the meshing relationship. The driven gear plate 1203 moves the threaded rod 1204 left and right through the threaded matching relationship. When the threaded rod 1204 moves to the left, it pushes the piston plate 1205 to move, and then pushes the flushing liquid into the nasogastric tube through the gun head assembly 9 to flush the inner wall of the nasogastric tube.

[0026] Furthermore, a handle 3 is fixedly connected to the right side of the bottom of the gun body 1, a button 4 for operation is provided on the left side of the handle 3, and a battery for power supply is provided inside the handle 3. The design of the handle 3 conforms to the principles of ergonomics, so that medical staff can reduce hand fatigue when using it for a long time. The battery and the servo motor 1207 are electrically connected.

[0027] Specifically, an observation window 5 is fixedly installed in the middle of the front side of the gun body 1, and a scale line 6 is set on the front side of the observation window 5. The setting of the observation window 5 allows medical staff to intuitively see the amount of flushing liquid in the gun body 1, which is convenient for timely replenishment of the flushing liquid.

[0028] Specifically, the piston assembly 12 includes a cover plate 1201, which is fixedly connected to the right end of the gun body 1. A pressure relief hole 1202 is opened above the cover plate 1201, and a driven gear disc 1203 is rotatably connected to the middle of the right side of the cover plate 1201.

[0029] Specifically, a threaded rod 1204 is threadedly connected to the middle part of the driven gear disc 1203, and the left end of the threaded rod 1204 passes through the cover plate 1201 and is fixedly connected to the inside of the gun body 1 with a piston plate 1205. The upper and lower sides of the piston plate 1205 are fixedly connected to the limiting blocks 1206, and the limiting blocks 1206 are slidably connected to the inside of the limiting groove 10. The setting of the limiting groove 10 not only limits the rotation of the piston plate 1205, but also provides it with a stable guide.

[0030] Furthermore, the piston assembly 12 also includes a servo motor 1207, which is fixedly installed inside the housing 2. The output end of the servo motor 1207 is fixedly connected to a drive gear 1208, which is engaged with the driven gear disc 1203. The engagement relationship between the drive gear 1208 and the driven gear disc 1203 ensures the stable transmission of power and the accuracy of rotation, providing reliable power support for the flushing process.

[0031] Furthermore, a circular limit plate 1209 is fixedly connected to the right end of the threaded rod 1204 . The provision of the circular limit plate 1209 prevents the threaded rod 1204 from excessively retracting during movement, thereby ensuring the safety and stability of the piston assembly 12 .

[0032] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
