Description

A diaphragm gastric tube

technical field

The utility model relates to a medical device, in particular to a diaphragm type gastric tube.

Background technique

At present, it has been widely used in clinical treatment to inject food or medicine into patients with related diseases by inserting a gastric tube. However, in the process of gastric tube insertion for treatment, gastric reflux and aspiration are likely to cause harm to patients. In order to ensure the safety of patients during the use of gastric tubes, it is necessary to solve the problem of gastric aspiration.

At present, the common way to solve this problem is to block the cardia with a balloon or use a cuff to block the esophagus to prevent reflux. Unfortunately, these methods have certain disadvantages in operation, such as excessive inflation of the balloon or cuff 1. If the pressure is too high, it is easy to cause gastric fundus ischemia, which will affect the patient's health and increase the pain of the patient; if the inflation is too small, the effect of preventing gastric juice reflux cannot be achieved. In addition, if a balloon or similar structure exerts too much pressure on the wall of the esophagus, it will affect blood flow to the local tissue, which may eventually lead to a pressure ulcer. The method of alternately inflating double balloons is not only complicated to operate, but also may cause double damage to the esophageal mucosa if improperly operated.

In view of the above problems, it is necessary to propose a simple and new anti-reflux gastric tube, so that patients can effectively avoid the occurrence of reflux and aspiration without causing further harm to the patient when the gastric tube is inserted. Maintain the health and personal safety of patients.

Detailed ways

The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the utility model, rather than limiting the protection scope of the utility model.

The diaphragm type gastric tube provided in this embodiment includes a suction device 2, a diaphragm ventilation tube 4 and an annular diaphragm 5 surrounding the outer wall of the gastric tube 6, the diaphragm 5 is located near the end of the gastric tube 6, and is separated from The top of gastric tube 6 is about 35cm (this value will be adjusted depending on the length of gastric tube). The gastric tube also includes a pharyngeal suction tube 1, an intelligent air injection pump 3, and a sensor 7. The pharyngeal suction tube 1 is arranged on the top of the gastric tube 6, and the outer end is opened for connecting the suction device 2, and the other end is inserted into the patient's oral cavity along with the gastric tube 6. The sputum and other secretions in the patient's oropharynx can be sucked out through the suction force of the aspirator 2, so as to prevent the secretions from being sucked into the trachea. The sensor 7 is arranged on the outer wall of the gastric tube 6 between the diaphragm 5 and the lower end of the gastric tube 6 Above, the signal output end is connected with the computer device 8, the pressure is analyzed by the computer device 8, and the result is sent to the intelligent air injection pump 3, one end of the intelligent air injection pump 3 is connected with the diaphragm ventilation tube 4, and the other end is connected with the computer device 8 Connected, the intelligent gas injection pump 3 determines whether to start gas injection and how much gas to inject according to the data input by the computer device 8, so as to realize the expansion and contraction of the diaphragm 4.

The pharynx suction tube 1 is a section of tubular silica gel structure, the outer end is open for connecting to the suction device 2, and the other port is connected to the starting end of the gastric tube 6 at 14-15 cm. The diameter of the pharynx suction tube 1 is generally 2-3 mm, and the length is generally It is 7-8cm, and it can be inserted into patient's throat together with stomach tube 6. After the stomach tube 6 is inserted, the medical staff can connect the open end of the pharyngeal suction tube 1 to the suction device 2. When the patient's throat produces sputum or other secretions, the suction of the suction device 2 can draw the sputum Suck out with secretions, in case the oropharyngeal part of the ooze is sucked into the trachea, causing unnecessary harm to the patient.

The sensor 7 is a pressure sensor, and it is a multi-sensor, which is attached to the wall of the gastric tube in a ring shape, and can feel the pressure from the stomach and the atmospheric pressure through the diaphragm 5, and transmit the pressure data to the computer device 8 through the signal transmission line.
