Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, and in particular comprises a nasogastric tube with an air pulse function. Background Art

[0002] As one of the basic nursing operations, gastric tube placement has been widely used in various clinical fields for many years. However, in real work, different nurses have to perform the operation for different patients with different diseases, and the problems of difficult and failed gastric tube placement are common. In the process of gastric tube placement, it is often necessary to cooperate with the patient to swallow, but in clinical practice, many patients are in a coma or cognitive disorder and cannot cooperate with the swallowing action; some patients start swallowing slowly and the swallowing reflex is difficult to trigger.

[0003] For patients who do not cooperate with swallowing or whose swallowing reflex is slow to start, three methods are commonly used clinically: 1) Taking the side-lying position to enlarge the cavity where the gastric tube enters the posterior pharyngeal hypopharyngeal segment, thereby increasing the probability of the gastric tube entering the esophagus. However, this method is a blind insertion method and there is a risk of the gastric tube accidentally entering the airway; 2) Stimulating the patient to swallow by feeding warm boiled water. This method can stimulate the patient to swallow, but patients with indwelling gastric tubes often suffer from swallowing disorders. Water is a highly fluid liquid that is difficult for patients with swallowing disorders to control, and it can easily enter the airway when passing through the throat, causing aspiration; 3) Indwelling the gastric tube through direct vision under laryngoscopy. This method is safe and effective, but it is costly, inconvenient to use, and difficult to implement.

[0004] Air pulse sensory stimulation training is a common training method for patients with dysphagia and has been proven to be effective in treating dysphagia. Air pulse is a natural mechanical stimulation that stimulates the area controlled by the glossopharyngeal nerve and vagus nerve. Air pulse sensory stimulation training stimulates the oropharyngeal mucosa through airflow impact, induces swallowing reflex, increases the sensitivity of the oropharyngeal mucosa, accelerates the initiation of swallowing, and achieves the effect of rehabilitation treatment.

[0005] However, in the prior art, there is a lack of nasogastric tubes that are compatible with the air pulse sensory stimulation training method, making it difficult to effectively exert the therapeutic effect of the air pulse sensory stimulation training method. Utility Model Content

[0006] The utility model aims to overcome the deficiencies in the prior art and provide a nasogastric tube with an air pulse function.

[0007] The nasogastric tube with air pulse function includes: a nasogastric tube body, a nasogastric tube wire and an air outlet tube. The nasogastric tube body is hollow inside, and a liquid food outlet is opened on the bottom side.

[0008] A joint is provided at the top of the nasogastric tube body, and the nasogastric tube wire and the vent tube are inserted into the nasogastric tube body from the joint; a balloon is connected to the top of the vent tube, and an air inlet is opened at the top of the balloon; a joint cap is connected to the top of the joint, and after the nasogastric tube body reaches the patient's stomach, only the nasogastric tube wire is inserted into the nasogastric tube body to block the gap between the nasogastric tube wire and the joint.

[0009] Preferably, a one-way valve is provided in the air inlet of the balloon, and gas flows into the balloon from the air inlet in a one-way manner, and the gas in the balloon flows into the nasogastric tube body through the air outlet and flows out from the liquid food outlet.

[0010] Preferably, one end of the connector is connected to the top of the nasogastric tube body, and the inner diameter of the end of the connector away from the nasogastric tube body is increased.

[0011] Preferably, one end of the connector cap is hinged on the connector; the connector cap is opened when the tracheal outlet tube is inserted into the nasogastric tube body.

[0012] Preferably, a scale is provided on the outer wall of the nasogastric tube body to mark the insertion depth of the nasogastric tube body.

[0013] The beneficial effects of the utility model are:

[0014] 1) The utility model exhausts air to the nasogastric tube body through the air outlet tube with a balloon, and is used to give air pulse stimulation to the area around the tonsils innervated by the tongue and pharyngeal nerves, inducing swallowing reflex, thereby improving the success rate of tube placement, shortening the intubation time, and alleviating the patient's pain. It is also safer than the blind intubation method in the lateral decubitus position and the warm water feeding method, and is more convenient than the indwelling gastric tube method under direct laryngoscope vision, and has a lower cost.

[0015] 2) The utility model integrates the air pulse device and the nasogastric tube, and the liquid food outlet also serves as the air hole. The air pulse function can be switched to the nasogastric tube function by simply pulling out and plugging the trachea. The use steps are simple and the efficiency is improved.

[0017] Explanation of the reference numerals: nasogastric tube body 1 , connector 2 , nasogastric tube wire 3 , air outlet tube 4 , liquid food outlet 11 , connector cap 21 , balloon 41 , air inlet 42 , one-way valve 43 . DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the embodiments. The description of the following embodiments is only used to help understand the utility model. It should be pointed out that for ordinary people in this technical field, the utility model can also be modified in some ways without departing from the principle of the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.

[0019] As an example, Figure 1 As shown, this nasogastric tube with air pulse function includes: a nasogastric tube body 1, a nasogastric tube wire 3 and an air outlet tube 4. The nasogastric tube body 1 is hollow inside, and three liquid food outlets 11 are opened on the bottom side; the outer wall of the nasogastric tube body 1 is provided with a scale for marking the insertion depth of the nasogastric tube body 1 to confirm that the liquid food outlet 11 has reached the stomach.

[0020] A connector 2 is provided at the top of the nasogastric tube body 1, one end of the connector 2 is connected to the top of the nasogastric tube body 1, the inner diameter of the end of the connector 2 away from the nasogastric tube body 1 is increased, and a connector cap 21 is connected to the top of the connector 2, one end of the connector cap 21 is hinged on the connector 2; after the connector cap 21 is opened, the nasogastric tube wire 3 and the exhaust tube 4 are inserted into the nasogastric tube body 1 from the connector 2.

[0021] The top of the air outlet tube 4 is connected to a balloon 41, and an air inlet 42 is provided at the top of the balloon 41. A one-way valve 43 is provided in the air inlet 42 of the balloon 41, and gas flows into the balloon 41 from the air inlet 42 in a one-way manner to prevent gas from escaping from the air inlet 42 during squeezing. The gas in the balloon 41 flows into the nasogastric tube body 1 through the air outlet tube 4 and flows out from the liquid food outlet 11. Therefore, the liquid food outlet 11 also serves as an air outlet for air pulse sensory stimulation training. When the nasogastric tube body 1 is inserted into the throat and the patient is required to swallow, the balloon 41 is manually squeezed to give air pulse stimulation to the area around the tonsils innervated by the tongue and pharyngeal nerves, thereby inducing a swallowing reflex, increasing the sensitivity of the pharyngeal mucosa, and accelerating the start of swallowing, and the nasogastric tube body 1 can be successfully inserted.

[0022] Since the nasogastric tube body 1 has a certain length, the airflow generated when squeezing a conventional-sized balloon has been greatly reduced when passing through the gastric tube body and reaching the front end. In order to make the airflow as large as that generated by ordinary air pulse stimulation, the volume of the balloon 41 was increased in this study. The airflow generated when squeezing the enlarged version of the balloon 41 is sufficient to induce a swallowing reflex in the patient.

[0023] After the nasogastric tube body 1 is successfully intubated, the nasogastric tube body 1 is disconnected from the tracheal outlet tube 4, and the normal nasogastric feeding process is followed. The nasogastric tube wire 3 can be inserted into the nasogastric tube body 1 from the beginning. When the nasogastric tube body 1 is soft and difficult to control, it can be manipulated by the nasogastric tube wire 3. If the nasogastric tube body 1 is set to be moderately soft and hard, it can also be inserted into the nasogastric tube body 1 after the nasogastric tube body 1 is inserted.

[0024] In this embodiment, after the nasogastric tube body 1 reaches the patient's stomach, the nasogastric tube body 1 pulls out the trachea 4, inserts the nasogastric tube wire 3, and closes the joint cap 21 to block the gap between the nasogastric tube wire 3 and the joint 2, so that the contents of the patient's stomach will not overflow from the gap between the joint 2 and the nasogastric tube wire 3 along the nasogastric tube body 1.
