Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a multifunctional gastric tube. Background Art

[0002] Clinically, a gastric tube is a common medical device used to deliver nutrient solution to the stomach of patients who cannot swallow to replenish water and energy. However, since such patients usually have delayed gastric emptying due to weakness, impaired consciousness, anesthesia and sedation, it is easy for gastric contents to reflux during gastric tube feeding, causing micro-aspiration. In this case, if micro-aspiration cannot be discovered in time, it may induce aspiration pneumonia, aggravate the patient's condition, and seriously affect the patient's prognosis. Therefore, in practice, it is usually necessary to monitor the reflux of gastric contents during gastric tube feeding. At the same time, a considerable number of such patients need to be equipped with mechanical ventilation equipment such as ventilators for assisted breathing. At present, it is still impossible to monitor the patient's response intrathoracic pressure during gastric tube feeding, resulting in the inability to effectively guide mechanical ventilation during this process. Therefore, how to develop a new gastric tube structure that can monitor the reflux of gastric contents during gastric tube feeding, reduce aspiration pneumonia caused by reflux of gastric contents, and improve the quality of patient prognosis is a direction that technicians in this field need to study. Utility Model Content

[0003] The technical purpose of the utility model is to provide a multifunctional gastric tube, which can monitor the patient's reactive intrathoracic pressure during gastric tube feeding, thereby adjusting the parameters of mechanical ventilation in the process and improving the patient's breathing quality during gastric tube feeding.

[0004] The utility model discloses a multifunctional gastric tube, which comprises:

[0005] A nutrient solution tube, wherein one end of the tube body of the nutrient solution tube is provided with a nutrient solution connector, and the structure of the nutrient solution connector is configured to be connected to an external infusion device and to inject nutrient solution into the tube body of the nutrient solution tube; the other end of the tube body of the nutrient solution tube is provided with a nutrient solution outlet;

[0006] A balloon, the balloon being fixedly mounted on the outer tube wall of the nutrient solution tube;

[0007] An air delivery tube, wherein a portion of the outer wall of the air delivery tube is fixedly connected to the outer wall of the nutrient solution tube as a whole, and one end of the tube body of the air delivery tube is conductively connected to the balloon;

[0008] An esophageal pressure monitor is conductively connected to the other end of the tube body of the air tube. The esophageal pressure monitor inflates / deflates the balloon through the air tube and reads the pressure value at the balloon.

[0009] By adopting this technical solution: during the process of feeding through a gastric tube, the nutrient solution tube, balloon, and air supply tube are inserted into the patient's nasal cavity (the balloon is in an uninflated state at this time), and the nutrient solution outlet reaches the patient's stomach. At this time, the external infusion device is connected to the nutrient solution connector so that the nutrient solution enters the patient's stomach along the nutrient solution tube. At the same time, the esophageal pressure monitor is controlled to start, and air is supplied to the balloon through the air supply tube. The balloon bulges and is squeezed by the esophagus in the human body to generate a pressure value. The esophageal pressure monitor reads the pressure value, that is, the real-time detection of the patient's reactive intrathoracic pressure is realized. When the pressure value reaches the preset threshold, the working parameters of the ventilator should be adjusted accordingly.

[0010] Preferably, the multifunctional stomach tube further comprises: a detection tube, the outer wall of the detection tube being fixedly connected to the outer wall of the nutrient solution tube as a whole;

[0011] An electrode wire, one end of which is installed on the pH measuring sensor; a middle section of the electrode wire extends from one end of the tube body of the detection tube into the detection tube and passes through the tube cavity of the detection tube; the other end of the electrode wire extends from the other end of the tube body of the detection tube and is installed and connected with a pH detection electrode.

[0012] By adopting this technical solution: during the process of feeding through a gastric tube, the pH measuring sensor uses the pH detection electrode inserted into the patient's body with the monitoring tube to monitor the pH value in the patient's body. When the patient has gastric reflux, the refluxed gastric contents change the pH environment of the patient's esophagus. At this time, the change in the reading of the pH measuring sensor can be used to understand that the patient has gastric reflux.

[0013] Preferably, the portion of the electrode wire close to the pH detection electrode is bonded to the inner wall of the detection tube.

[0014] By adopting this technical solution, relative movement between the electrode wire and the detection tube is avoided, ensuring that the pH detection electrode is always located close to the other end of the tube body of the detection tube.

[0015] Preferably, the balloon is configured to be located between the nutrient solution outlet and the pH detection electrode.

[0016] By adopting this technical solution, the pH monitoring electrode is located at a position on the tube body of the nutrient solution tube that is farther away from the stomach when working, so that the pH value measured by it can be more accurate when confirming whether reflux of gastric contents occurs.

[0017] Preferably, it further comprises: an outer sleeve, wherein the outer sleeve is configured to be arranged outside the tube body of the detection tube and outside the partial tube bodies of the nutrient solution tube and the gas supply tube.

[0018] By adopting this technical solution, the outer sleeve is used to fix the relative positions of the detection tube, the nutrient solution tube and the gas delivery tube, so that at least part of the outer edges of the tube bodies of the three are smoother.

[0019] Compared with the prior art, the utility model has achieved the following technical advances:

[0020] Firstly, the utility model can monitor the patient's reactive intrathoracic pressure during gastric tube feeding, thereby adjusting the parameters of mechanical ventilation during the process and improving the patient's breathing quality during gastric tube feeding.

[0021] Secondly, the utility model can further detect the reflux of gastric contents in a timely manner to avoid inducing aspiration pneumonia.

[0022] Finally, the system of the utility model is easy to operate, easy to program and implement, and easy to use clinically. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1, please refer to Figure 1-2 :

[0029] A multifunctional gastric tube, comprising: a nutrient solution tube 100, an air delivery tube 200, a detection tube 300, a balloon 210, an esophageal pressure monitor 220 and a pH measurement sensor 310. Among them:

[0030] A nutrient solution connector 110 is provided at one end of the tube body of the nutrient solution tube 100, and the structure of the nutrient solution connector 110 is configured to be used for connecting an external infusion device and injecting nutrient solution into the tube body of the nutrient solution tube 100; a nutrient solution outlet 120 is provided at the other end of the tube body of the nutrient solution tube 100.

[0031] The balloon 210 is fixedly mounted on the outer tube wall of the nutrient solution tube 100; part of the outer tube wall of the gas tube 200 is fixedly connected to the outer tube wall of the nutrient solution tube 100 as a whole, and one end of the tube body of the gas tube 200 is conductively connected to the balloon 210; the esophageal pressure monitor 220 is conductively connected to the other end of the tube body of the gas tube 200, and the esophageal pressure monitor 220 inflates / exhausts the balloon 210 through the gas tube 200 and reads the pressure value at the balloon 210. In this example: the outer tube wall of the detection tube 300 is fixedly connected to the outer tube wall of the nutrient solution tube 100 as a whole;

[0032] One end of the electrode wire 320 is connected to the pH measurement sensor 310; the middle section of the electrode wire 320 extends from one end of the tube body of the detection tube 300 into the detection tube 300 and passes through the tube cavity of the detection tube 300; the other end of the electrode wire 320 extends from the other end of the tube body of the detection tube 300 and is installed and connected with a pH detection electrode 330.

[0033] Furthermore, in order to prevent the electrode wire and the detection tube 300 from moving relative to each other, the pH detection electrode 330 is always located near the other end of the detection tube 300. In this example, the portion of the electrode wire 320 close to the pH detection electrode 330 is bonded to the inner wall of the detection tube 300.

[0034] In this example, the balloon 210 is configured to be located between the nutrient solution outlet 120 and the pH detection electrode 330. The pH detection electrode 330 is located about 55 cm from the patient's nasal cavity.

[0035] Furthermore, in this example, an outer sleeve 400 is also included, and the outer sleeve 400 is configured to be arranged outside the tube body of the detection tube 300 and outside part of the tube body of the nutrient solution tube 100 and the gas supply tube 200.

[0036] In practice, the working process is as follows: during the process of feeding through a gastric tube, the nutrient solution tube 100, the balloon 210, and the air supply tube 200 are inserted into the patient's nasal cavity (the balloon 210 is in an uninflated state at this time), and the nutrient solution outlet 120 reaches the patient's stomach. At this time, the external infusion device is connected to the nutrient solution connector 110, so that the nutrient solution enters the patient's stomach along the nutrient solution tube 100. At the same time, the esophageal pressure monitor 220 is controlled to start, and the balloon 210 is gassed through the air supply tube 200. The balloon 210 swells and is squeezed by the esophagus in the human body to generate a pressure value. The esophageal pressure monitor 220 reads the pressure value, that is, the real-time detection of the patient's reactive intrathoracic pressure is realized. When the pressure value reaches the preset threshold, the working parameters of the ventilator should be adjusted accordingly. The pH measurement sensor 310 uses the pH detection electrode 330 inserted into the patient's body with the monitoring tube to monitor the pH value in the patient's body. When the patient has gastric reflux, the refluxed gastric contents change the pH environment of the patient's esophagus. At this time, the change in the reading of the pH measurement sensor 310 can be used to understand that the patient has gastric reflux.

[0037] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
