Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a disposable water-bag nasogastric tube. Background Art

[0002] As an important medical auxiliary tool, the nasogastric tube can effectively provide nutrients, prevent food reflux and aspiration, reduce the occurrence of aspiration pneumonia, and is of great significance to the patient's recovery. However, there are some technical defects at present: 1. It is inconvenient to enter the pylorus. The front end of the tube is relatively rigid and may accidentally touch the fragile parts of the patient's body when entering the small intestine, causing bleeding. Infection and other problems cause discomfort to the patient; 2. It is easy to fall off. During the movement of the nasogastric tube between the stomach and the small intestine, it may be affected by the pressure during catheterization or defecation, and thus be pushed out of the body. This phenomenon will not only affect the treatment effect, but may also cause pain and inconvenience to the patient.

[0003] Therefore, the present invention proposes a disposable water-bag type nasogastric tube to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a disposable water-bag type nasogastric tube to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a disposable water-bag type nasogastric tube, characterized in that it comprises a gastric tube body, a gastric tube joint and a water injection pipe joint, the gastric tube body is provided with a nutrient solution injection channel and a water injection channel, the nutrient solution injection channel and the water injection channel are isolated from each other, a water bag is provided at the head end of the gastric tube body, a water injection port is provided at the position corresponding to the water bag, the gastric tube joint is connected to the tail end of the gastric tube body, and the water injection pipe joint is connected to the tail end of the water injection channel through a water injection connecting pipe.

[0006] Preferably, the water bag is a 30mm sphere when filled with water.

[0007] Preferably, a clear water coating is coated on the outer wall of the water bag.

[0008] Preferably, an indicator balloon is provided at the connection between the water injection pipe joint and the water injection connecting pipe.

[0009] Preferably, a one-way valve is provided at the tail end of the water injection pipe joint.

[0010] Preferably, the water injection connecting pipe is connected to the tail end of the water injection channel by injection molding.

[0011] Preferably, the stomach tube body is a flexible hose.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adds a water bag to enable the nasogastric tube to pass through the human pylorus more smoothly, reduce damage to vulnerable parts of the human body, and have the function of fixing and preventing it from falling off. In this case, it will reduce stimulation to the stomach and intestines and reduce the incidence of adverse reactions. The nasogastric tube can smoothly reach the small intestine and can significantly reduce the risk of accidental ingestion, so as to facilitate better operation and increase the fault tolerance during use.

[0013] 2. The present invention installs a one-way valve and an indicating balloon on the water injection pipe joint to determine the water pressure, ensuring that the water pressure will not be too high or too low to cause harm to the human body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1, see Figure 1-3 As shown, a disposable water-bag type nasogastric tube comprises a gastric tube body 1, a gastric tube connector 2 and a water injection pipe connector 8. A nutrient solution injection channel 3 and a water injection channel 4 are provided in the gastric tube body 1. The nutrient solution injection channel 3 and the water injection channel 4 are isolated from each other. A water bag 6 is provided at the head end of the gastric tube body 1, and a water injection port 5 is provided at a position corresponding to the water bag 6. The gastric tube connector 2 is connected to the tail end of the gastric tube body 1, and the water injection pipe connector 8 is connected to the tail end of the water injection channel 4 through a water injection connecting pipe 7.

[0018] In Example 2, the water bag 6 is a 30mm sphere when filled with water. The water bag 6 in the water-filled state wraps the head end of the gastric tube body 1, which can prevent the rigid part of the head end of the gastric tube body 1 from directly touching the human body and causing pain to the patient.

[0019] In Example 3, the outer wall of the water bladder bag 6 is coated with a clear water coating, which can facilitate the tip of the gastric tube body 1 to pass through the pylorus and enter the small intestine.

[0020] In Example 4, an indicator balloon 9 is provided at the connection between the water injection pipe joint 8 and the water injection connecting pipe 7. The indicator balloon 9 can be used to determine the water pressure to ensure that the water pressure is not too high or too low to cause harm to the human body.

[0021] In embodiment 5, a one-way valve 10 is provided at the tail end of the water injection pipe joint 8, and water can be injected into the water injection pipe joint 8 through the one-way valve 10, and the injected water flows into the water bag 6 through the water injection connecting pipe 7 and the water injection channel 4.

[0022] In Example 6, the water injection connecting pipe 7 is connected to the tail end of the water injection channel 4 by injection molding.

[0023] In Example 7, the stomach tube body 1 is a flexible hose.

[0024] Working principle: In the actual operation process, the medical staff first lubricates the head end of the gastric tube body 1. The patient is in a suitable position and the gastric tube body 1 is slowly inserted from the nasal cavity. When it reaches the throat, the patient is asked to swallow and the catheter is inserted to the required length. When the gastric tube body 1 enters the stomach, an appropriate amount of water is injected into the water bag 6 through the one-way valve 10 to make it into a sphere, and the tube position is confirmed by suctioning gastric juice, X-rays, etc.

[0025] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
