Description

Technical Field

[0001] The present invention relates to the technical field related to medical device technology, and in particular to an enteral nutrition gastric retention detection device. Background Art

[0002] Enteral nutrition is a nutritional support method that provides nutrients required for metabolism and various other nutrients through the gastrointestinal tract. There are two ways of enteral nutrition: oral and catheter input. The catheter input includes nasogastric tube, nasoduodenal tube, nasojejunal tube and gastrojejunostomy tube. Compared with parenteral nutrition support, the superiority of enteral nutrition is not only reflected in the direct absorption and utilization of nutrients through the intestine, which is more physiological, convenient to administer, and low in cost, but also shows the advantage of helping to maintain the integrity of the intestinal mucosal structure and barrier function. Therefore, when deciding what kind of nutritional support to provide, enteral nutrition has become a consensus among many clinical physicians.

[0003] For patients who are fed through the stomach, the amount of enteral nutrition solution in the patient's stomach needs to be controlled within a reasonable range considering the patient's digestive capacity to prevent malnutrition problems caused by insufficient nutrition solution, or nausea, vomiting, and reflux caused by excessive nutrition solution, which may cause suffocation in severe cases.

[0004] The current clinical monitoring method is to extract the nutrient solution in the stomach every 4 hours after the patient has fed a certain amount, and judge whether to continue feeding by the volume of the nutrient solution that can be extracted. Nurses are required to extract frequently, which increases the workload of nurses. Due to the uncertain position of the gastric tube inserted into the nutrient solution, the amount extracted may be too small compared to the actual amount, resulting in a large amount of gastric retention, which may cause nausea, vomiting, and reflux to the patient. In severe cases, it may cause suffocation and affect the patient's life and health. The Chinese utility model patent "Gastric Retention Monitoring Device" with application number "202121074130.1" can only observe the image of the patient's stomach, and medical staff are required to make judgments. It is also necessary to observe and judge regularly. For patients who are feeding nutrient solution through the nose, they still need to manually turn on and off the enteral nutrition pump to feed and pause the enteral nutrition solution, which does not reduce the workload of medical staff. At the same time, the nutrient solution is a non-transparent liquid, and the camera cannot penetrate the nutrient solution, so the error in judging the amount of nutrient solution is large. Summary of the invention

[0005] In order to solve the defects of the prior art, the present invention provides an enteral nutrition gastric retention detection device.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] The present invention discloses an enteral nutrition gastric retention detection device, comprising a gastric tube assembly, an ultrasonic detection device and an enteral nutrition pump; the gastric tube assembly comprises a gastric tube body inserted into the human stomach, the end of the gastric tube body is connected to an enteral nutrition pump tube, the enteral nutrition pump tube is connected to the enteral nutrition pump, and an ultrasonic probe is also arranged at the front end of the gastric tube body, a transmission line cavity is arranged on the gastric tube body for an ultrasonic feeder on the ultrasonic probe to pass through, and the ultrasonic probe is connected to the ultrasonic detection device via the ultrasonic feeder;

[0008] The ultrasonic probe is configured to emit ultrasonic waves in all directions and receive ultrasonic waves reflected in all directions. The ultrasonic probe is used to detect the depth of the nutrient solution in the stomach. The ultrasonic detection device calculates the volume of the nutrient solution in the stomach by obtaining depths at different positions through the ultrasonic probe. When the gastric retention volume meets the set volume, the enteral nutrition pump is controlled to stop feeding. When the gastric retention volume is less than the set value, the ultrasonic detection device controls the enteral nutrition solution to continue feeding.

[0009] As a preferred technical solution of the present invention, the ultrasonic probe includes a shell arranged at the front end of the gastric tube body, and an ultrasonic generator and an ultrasonic receiver are installed in the shell through a rotating mechanism. The ultrasonic generator is used to emit ultrasonic waves, and the ultrasonic receiver is used to receive reflected ultrasonic waves. The rotating mechanism drives the ultrasonic generator and the ultrasonic receiver to perform spatial scanning of the human stomach.

[0010] As a preferred technical solution of the present invention, the rotating mechanism includes a bracket arranged inside the shell, a first rotating seat that rotates 180 degrees up and down is provided on the top of the bracket, a vertical rotating rod is provided on the rotating seat, a second rotating seat that rotates horizontally is provided on the upper end of the rotating rod, a third rotating seat that rotates vertically is provided on the second rotating seat, and the ultrasonic generator and ultrasonic receiver are both installed on the third rotating seat.

[0011] As a preferred technical solution of the present invention, the ultrasonic probe is driven by the rotating mechanism to detect the depth of the nutrient solution in the stomach. First, the first rotating seat rotates to transfer the ultrasonic generator and the ultrasonic receiver to the upper part, and then the second rotating seat and the third rotating seat work to scan the upper half of the human stomach to obtain the depth of the nutrient solution at each position in the upper half of the stomach. Then, the first rotating seat rotates to transfer the ultrasonic generator and the ultrasonic receiver to the lower part, and then the second rotating seat and the third rotating seat work to scan the lower half of the human stomach to obtain the depth of the nutrient solution at each position in the lower half of the stomach.

[0012] As a preferred technical solution of the present invention, the ultrasonic detection device is also provided with a nutrient solution type setting module and a gastric retention volume setting module. The ultrasonic detection device is also provided with a control switch for controlling the enteral nutrition pump, wherein the nutrient solution type is set by the nutrient solution type setting module, and the gastric retention volume setting module is used to set the gastric retention volume. When the gastric retention volume meets the set volume, the enteral nutrition pump is controlled to stop feeding. When the gastric retention volume is less than the set value, the ultrasonic detection device controls the enteral nutrition pump to continue feeding.

[0013] As a preferred technical solution of the present invention, the stomach tube body is made of medical plastic.

[0014] As a preferred technical solution of the present invention, a patient setting module is further provided in the ultrasonic detection device, and the patient setting module is used to set different feeding amounts for patients with different weights and medical conditions.

[0015] As a preferred technical solution of the present invention, the ultrasonic detection device measures the volume of gastric retention in the human stomach every n hours.

[0016] The beneficial effects of the present invention are:

[0017] 1. The ultrasonic probe in the enteral nutrition gastric retention detection device is provided with an ultrasonic probe that emits ultrasonic waves in all directions and receives ultrasonic waves reflected in all directions. The ultrasonic probe is used to detect the depth of the nutrient solution in the stomach. The ultrasonic detection device obtains the depth of different positions through the ultrasonic probe to calculate the volume of the nutrient solution in the stomach. When the gastric retention volume meets the set volume, the enteral nutrition pump is controlled to stop feeding. When the gastric retention volume is less than the set value, the ultrasonic detection device controls the enteral nutrition solution to continue feeding. The present invention measures its ultrasonic characteristics and inputs them into the ultrasonic detection device. When used, the ultrasonic detection device sets the type of enteral nutrition solution used, and sets the volume of gastric retention according to the patient's condition. That is, when the ultrasonic detection device detects that the volume of the nutrient solution in the patient's stomach exceeds the set gastric retention volume, the ultrasonic detection device controls the enteral nutrition pump to close through the signal line. When the detected volume is less than the set gastric retention volume, the enteral nutrition pump is controlled to start and the patient is fed, thereby achieving the purpose of automatically controlling the gastric retention volume of the patient and meeting the nutritional needs of the patient.

[0018] 2. This enteral nutrition gastric retention detection device uses an ultrasonic probe to measure the depth of the nutrient solution in the stomach from all directions, and at the same time, the volume of the nutrient solution in the stomach is inversely calculated according to the algorithm. The volume is judged in the ultrasonic detection device whether to stop feeding, and the signal line is transmitted to the enteral nutrition pump to control the switch of the enteral nutrition pump. All are automated, and no nursing staff is required to perform detection. After the gastric retention volume is calculated by the ultrasonic detection device in the present invention, different feeding amounts can be set according to patients with different weights and conditions. Patients will not have the problem of malnutrition and overfeeding, which is helpful for the health of patients. Only a set of ultrasonic probes and ultrasonic feeders need to be added to the existing gastric tube. The ultrasonic probes and ultrasonic feeders are wrapped by gastric tube materials to avoid gastric fluid from corroding the ultrasonic probes and ultrasonic feeders. At the same time, the ultrasonic probes and ultrasonic feeders do not contact the patient and have good tolerance. The ultrasonic detection device can convert the acoustic wave characteristics detected by the ultrasonic probe into length dimensions according to the acoustic wave characteristics of different types of nutrient solutions using the corresponding algorithm, and then calculate the volume of the nutrient solution, and set the corresponding nutrient solution on the ultrasonic detection device to achieve the purpose of automated use, and has a wide range of applications.
