Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a multifunctional stomach tube combination device capable of dynamically monitoring gastric residual volume. Background Art

[0002] A gastric tube is a medical device used to deliver nutrient solution to the stomach of patients who cannot swallow in order to replenish water and energy. In clinical practice, gastric residual volume monitoring is the most commonly used method to assess gastric emptying and is an important indicator for assessing a patient's tolerance to enteral nutrition. It is of great significance for patients in internal and external medicine who need enteral nutrition, especially critically ill patients and patients with mechanical ventilation. Before a patient uses a gastric tube to eat, the nurse needs to first detect the residual volume in the patient's stomach (i.e., residual liquid retained in the stomach) to avoid the residual volume in the stomach exceeding a certain limit, causing vomiting or even aspiration in the patient who is eating. The methods currently used in clinical practice to assess gastric residual volume include gastric tube aspiration, ultrasonic measurement, and x-ray measurement. The main problems of these methods include: 1. It is impossible to reflect the dynamic changes of gastric residual volume in real time; 2. It is impossible to timely aspirate excessive residual liquid retained in the stomach during the monitoring process. Therefore, how to develop a new type of gastric tube structure that can dynamically monitor the patient's gastric residual volume during gastric tube feeding and reduce the phenomenon of vomiting and aspiration into the lungs. It is a direction that technicians in this field need to study. Utility Model Content

[0016] By adopting this technical solution: during the monitoring process, the head end of the feeding tube is tilted up under the action of the floating airbag, ensuring that each sensing chip is in full contact with the residual volume in the stomach, thereby improving the accuracy of monitoring.

[0017] Preferably, a light sensing chip and a position chip are integrated and mounted on the sensing chip.

[0032] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0033] Example 1, please refer to Figure 1-4 :

[0034] A multifunctional gastric tube assembly device capable of dynamically monitoring gastric residual volume comprises: a feeding tube 110, a negative pressure suction tube 120, a floating air bag 200, an airway tube 130, a sensor chip 300, and a monitor 400. Among them:

[0035] The tail end of the feeding tube 110 is used to be retained outside the patient's body during gastric tube feeding and connected to a nutrient solution injection device. The head end of the feeding tube 110 is provided with a nutrient solution outlet for extending into the patient's stomach during gastric tube feeding.

[0036] The floating airbag 200 is installed on the outer wall of the feeding tube 110 and is arranged near the nutrient solution outlet. One end of the airway tube 130 is connected to the floating airbag 200, and the other end is provided with a one-way air valve 131 for connecting to an external air source; the middle section of the airway tube 130 is fixedly connected to the outer tube wall of the feeding tube 110 as a whole. When working, the external air source device controls the inflation / deflation state of the floating airbag 200 through the one-way air valve 131 through the airway tube 130.

[0037] Part of the negative pressure suction tube 120 is fixedly connected to the outer tube wall of the feeding tube 110 as a whole; at least one adsorption hole 121 is opened on the tube wall of the negative pressure suction tube 120 to connect the inside and outside of the negative pressure suction tube 120; one end of the negative pressure suction tube 120 is configured to be connected to an external negative pressure suction device 500. In this example: the tube body of the negative pressure suction tube 120 does not extend to the inside of the floating airbag 200.

[0038] In this example, there are five sensor chips 300, which are distributed on the outer wall of the feeding tube 110 and located on the side of the floating airbag 200 facing away from the nutrient solution outlet. That is, the floating airbag 200 is located between the sensor chip 300 and the nutrient solution outlet. Furthermore, the five sensor chips 300 are arranged in sequence on the stomach tube body along the extension direction of the feeding tube 110, and the spacing between adjacent sensor chips 300 remains consistent (about 20 cm).

[0039] The monitor 400 is signal-connected to the sensing chip 300, and the monitor 400 is used to read the sensing signal obtained by the sensing chip 300. The sensing chip 300 is integrated with a light sensing chip, a position chip and a wireless output chip. Among them, the position chip is used to obtain its own spatial data in the stomach. The light sensing chip is used to obtain the photosensitive data of the residual amount in the stomach, and medical staff can judge the level of fluid retention in the stomach based on the photosensitive data. The wireless output chip is used to convert the data obtained by the light sensing chip and the position chip into wireless signal output. A wireless signal receiver is installed on the monitor 400, and the wireless signal receiver is used to receive the wireless signal.

[0040] It should be noted that the light sensing chip, the position chip, and the wireless output chip are all mature technical components on the market, and there are many options, so their specific models and structures are not described and illustrated in this article.

[0041] During tube feeding:

[0042] First, the external air source device is activated to inflate the floating airbag 200 through the airway tube 130. After inflation, the floating airbag 200 drives the feeding tube 110 and the negative pressure suction tube 120 to enter the patient's stomach and float horizontally with the retained liquid in the stomach. At the same time, the residual volume of the stomach is sensed by the sensing chip 300 distributed on the tube wall of the feeding tube 110, and the residual volume of the stomach is read by the monitor 400. In this way, real-time dynamic monitoring of the patient's gastric residual volume is achieved. In the above process, when the patient's gastric residual volume reaches a certain limit through the monitor 400, the external negative pressure suction device 500 is activated to drain the residual liquid retained in the stomach from the stomach through the negative pressure suction tube 120, so as to avoid the patient's vomiting in time.

[0043] Optionally, a display may be added to the monitoring device 400, and the display is used to display the position of the sensing chip 300 in the stomach, and simulate the position trajectory to determine the situation of the device in the stomach.

[0044] Optionally, the monitoring device 400 may be further equipped with an alarm device, in which a gastric residual volume threshold is pre-written, and an alarm is output when the gastric residual volume reaches the threshold.

[0045] Optionally, a control device may be further installed on the monitoring instrument 400, and the control device is used to connect with the signal of the negative pressure suction device 500 and control the negative pressure suction device 500 to start automatically while outputting an alarm.

[0046] Optionally, the monitoring instrument 400 may be implemented using a programmable controller.

[0047] Optionally, the monitor 400, the negative pressure suction device 500, and the air source device can be independently arranged; or they can be integrated and installed on the same device.

[0048] 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.
