Description

Technical Field

[0001] This utility model relates to the field of gastric residue monitoring technology, specifically to a gastric tube for monitoring gastric residue based on a pressure sensor. Background Technology

[0002] A gastric tube is used in special circumstances to help patients who cannot swallow to deliver necessary water and food. Gastric tubes are generally made of polyurethane or silicone and come in different sizes and lengths. Gastric tubes are divided into oral gastric tubes and nasogastric tubes.

[0003] A Chinese patent publication number of 202122930345.5 discloses a gastric tube for monitoring gastric residual volume. The tube includes a main body with an insertion end and a feeding end. The insertion end has a suction tip, and the end of the suction tip away from the main body has a hollow probe with a detector inside, located near the suction tip. The feeding end of the main body away from the suction tip has a control assembly, including a control board. By adding a probe to the end of the main body and inserting it into the stomach, the detector detects the residual volume in the stomach. The nurse can determine the amount of residual gastric contents by observing whether a green or red LED light illuminates.

[0004] Although the aforementioned patent can effectively detect the amount of residue in a patient's stomach, in actual operation, the patient's stomach often undergoes peristalsis, which causes the detector position to change, and in turn, changes the hydraulic transmission path. This results in significant fluctuations in the measurement data and poor detection results. Utility Model Content

[0005] The purpose of this invention is to provide a gastric tube for monitoring gastric residual volume based on a pressure sensor, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a gastric tube for monitoring gastric residual volume based on a pressure sensor, comprising a detector and a gastric tube;

[0007] An air bladder is fixedly installed on one side of the gastric tube. The detector is fixedly installed on the outer wall of one side of the air bladder. A wire is fixedly connected to one side of the detector and passes through the gastric tube. An overpressure safety valve is fixedly installed on one side of the air bladder. An air delivery tube is connected to the other side of the air bladder. The air delivery tube passes through the gastric tube and is connected to an air supply tube. One end of the air supply tube is connected to a one-way valve. An air injection tube is connected to one side of the one-way valve. A limit plate is fixedly connected to the inner wall of the gastric tube. A suction tube is fixedly installed on one side of the limit plate.

[0008] Preferably, a mounting base is fixedly installed at one end of the gastric tube, and a threaded sleeve is fitted on the outer wall of the mounting base.

[0009] Preferably, the gas supply pipe and the wire pass through the limiting plate, and the gas supply pipe and the wire are fixedly connected to the limiting plate.

[0010] Preferably, the airbag is made of medical-grade silicone, the airbag has a ring-shaped structure, and the outer wall of the airbag has a smooth transition.

[0011] Preferably, the outer wall of the conductor is provided with an anti-interference coating, and one end of the conductor is fixedly connected to an adapter.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by setting a ring-shaped medical silicone airbag on one side of the gastric tube, when the airbag is inflated, it can always fit tightly and stably against the stomach wall under various movement states such as gastric peristalsis, so that the detector fixed on the outer wall of the airbag maintains stable contact with the stomach wall, reducing the sensor position change caused by gastric peristalsis, thereby stabilizing the hydraulic transmission path, avoiding large fluctuations in measurement data, and improving the accuracy of gastric residual volume monitoring.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 The present invention provides the following technical solution:

[0019] Example 1: Gastric residual volume monitoring gastric tube based on pressure sensor, including detector 1 and gastric tube 2;

[0020] An air bladder 3 is fixedly installed on one side of the gastric tube 2. A detector 1 is fixedly installed on the outer wall of one side of the air bladder 3. A wire 4 is fixedly connected to one side of the detector 1. The wire 4 passes through the gastric tube 2. An overpressure safety valve 5 is fixedly installed on one side of the air bladder 3. An air delivery tube 6 is connected to the other side of the air bladder 3. The air delivery tube 6 passes through the gastric tube 2 and is connected to an air supply tube 7. One end of the air supply tube 7 is connected to a one-way valve 8. One side of the one-way valve 8 is connected to an air injection tube 9. A limit plate 10 is fixedly connected to the inner wall of the gastric tube 2. A suction tube 11 is fixedly installed on one side of the limit plate 10.

[0021] During use, the gastric tube 2 is inserted into the patient's stomach, and the air bag 3 is inflated through the air inflation tube 9, the inflation tube, and the air delivery tube 6. During inflation, the one-way valve 8 prevents gas backflow. When the air bag 3 is inflated, the detector 1 can remain in close contact with the stomach wall at all times during various stomach movements. The air bag 3, made of medical-grade silicone, will not cause adverse reactions such as inflammation or allergies during long-term placement in the stomach. Furthermore, the overpressure safety valve 5 effectively prevents damage to the gastric mucosa caused by over-inflation of the air bag 3, ensuring the patient's stomach safety.

[0022] Example 2: This example differs from Example 1 in that: a mounting base 12 is fixedly installed at one end of the gastric tube 2, and a threaded sleeve 13 is fitted on the outer wall of the mounting base 12; the gas delivery tube 7 and the wire 4 pass through the limiting plate 10; the gas delivery tube 7 and the wire 4 are fixedly connected to the limiting plate 10; the air bag 3 is made of medical silicone; the air bag 3 has a ring structure design; the outer wall of the air bag 3 has a smooth transition; the outer wall of the wire 4 is provided with an anti-interference coating; and an adapter is fixedly connected to one end of the wire 4.

[0023] In use, the gastric tube 2 can be extended and connected through the mounting base 12 and the threaded sleeve 13. During the monitoring process, the electrical signal of the detector 1 can be transferred through the wire 4. The limiting plate 10 can effectively fix the gas delivery tube 7, the wire 4, and the suction tube 11.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
