Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically to a sleeve device integrating esophageal reflux and vomiting reflex detection and an application method thereof. Background Art

[0002] In the late stage of treatment for many diseases, endotracheal intubation is a common treatment method. However, after intubation, patients may develop stress ulcers, leading to frequent vomiting. Although respiratory failure may be improved, frequent vomiting can easily lead to aspiration after the trachea is removed, causing sudden suffocation of the patient, which seriously threatens the patient's life safety. Prevention of aspiration mainly focuses on two aspects, one is the monitoring of vomiting reflex action, and the other is the monitoring of esophageal reflux. If the monitoring data of these two states can be obtained, medical staff can make aspiration judgments. However, the current method for esophageal reflux is to monitor the pH value of esophageal gas. The gas monitoring method is not accurate. At the same time, gas monitoring does not mean the presence of actual reflux. Even if the pH of the exhaled gas from the esophagus is monitored to be acidic, it does not mean that reflux has reached the throat. This difference causes the current pH monitoring method to be only a reference for prevention of aspiration. Based on this situation, there is an urgent need for a tracheal tube device that can detect esophageal reflux and vomiting reflex in real time. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a sleeve device integrating esophageal reflux and vomiting reflex detection, and also provide an application method of the sleeve device integrating esophageal reflux and vomiting reflex detection in view of the above-mentioned defects of the prior art.

[0004] The technical solution adopted by the present invention to solve its technical problem is: A sleeve device for integrated esophageal reflux and vomiting reflex detection is constructed, wherein the sleeve comprises a sleeve, the front end of which is provided with an annular detection head; the outer surface of the detection head is provided with a plurality of airbags distributed in a petal shape, the plurality of airbags are connected through an airway, and the other end of the airway extends outside the sleeve; the device also comprises an air-filling and air-discharging unit for filling and discharging the airway and an air pressure sensor for detecting the air pressure inside the airway; the inner wall of the detection head is provided with an annular liquid accumulation groove, the inner wall of the liquid accumulation groove is provided with an annular slide rail, and a pH detection probe for detecting the pH value of the liquid in the liquid accumulation groove is slidably provided on the slide rail; a plurality of liquid outlets connected with the liquid accumulation groove are provided on the outer surface of the detection head, one or more liquid outlets are provided in the middle space adjacent to the airbags, and the liquid outlets are closed when the airbags are inflated; the device also comprises a control host, the air-filling and air-discharging unit is controlled and operated by the control host; the control host receives the monitoring data of the air pressure sensor and the pH detection probe, and feeds back the monitoring results to the outside.

[0005] The sleeve device for integrated esophageal reflux and vomiting reflex detection described in the present invention is characterized in that the internal space of the fluid collection tank is narrow at the top and wide at the bottom, and the slide rail is arranged at the upper end of the internal space of the fluid collection tank; the tail of the pH detection probe is arranged on the slide rail, and the head extends into the lower end of the internal space of the fluid collection tank.

[0006] In the sleeve device for integrated esophageal reflux and vomiting reflex detection of the present invention, the liquid outlet is in a teardrop shape that is narrow at the top and wide at the bottom, and is directly connected to the lower end of the internal space of the liquid accumulation tank.

[0007] The sleeve device for integrated esophageal reflux and vomiting reflex detection of the present invention is characterized in that a flexible buffer sleeve connected to the detection head is provided at the front end of the sleeve.

[0008] In the sleeve device for integrated esophageal reflux and vomiting reflex detection of the present invention, the connecting line of the pH detection probe passes through the flexible buffer sleeve.

[0009] The sleeve device for integrated esophageal reflux and vomiting reflex detection of the present invention is characterized in that an airway tube clamp for clamping and fixing the airway tube is arranged inside the flexible buffer sleeve.

[0010] An application method of a cannula device integrating esophageal reflux and vomiting reflex detection is applied to the cannula device integrating esophageal reflux and vomiting reflex detection as described above, wherein the method comprises the steps of: After the detection head is placed in the appropriate position of the throat, the airway is inflated through the inflation and deflation unit, and multiple air bags are inflated to squeeze and support the inner wall of the throat. The inflation of the air bags will block the liquid outlet while the fixation is completed. During monitoring, the patient is in a lying position, and the pH detection probe slides to the bottom of the slide rail by its own weight. When the throat has a vomiting reflex movement, it will squeeze multiple air bags, causing the air pressure inside the airway to change. The air pressure sensor monitors the air pressure reading and sends it to the control host; When there is esophageal reflux reaching the throat and entering the effusion tank, the pH detection probe will contact and detect the esophageal reflux, and send the detection result to the control host; each time the control host receives a pH value detection result lower than the set value, it controls the inflation and deflation unit to deflate first and then inflate, and the airbag contracts first and then expands. When the airbag contracts, the reflux in the effusion tank is discharged along the liquid outlet; The control host sends the collected monitoring air pressure readings and pH value data to the outside world.

[0011] The beneficial effects of the present invention are as follows: after the detection head is placed in a suitable position in the throat, the airway is inflated by the inflation and deflation unit, and multiple airbags swell to squeeze and support the inner wall of the throat, and the inflation of the airbags will block the liquid outlet when the fixation is completed; during monitoring, the patient is in a lying position, and the pH detection probe slides to the bottom of the slide rail by its own weight; when the throat has a vomiting reflex movement, multiple airbags will be squeezed, so that the air pressure inside the airway changes, and the air pressure sensor monitors the air pressure reading and sends it to the control host; when there is esophageal reflux reaching the throat and entering the effusion tank, the pH detection probe will contact and detect the esophageal reflux, and send the detection result to the control host; each time the control host receives a pH value detection result lower than the set value, the inflation and deflation unit is controlled to perform an action of first deflation and then inflation, and the airbag first shrinks and then expands, and the reflux in the effusion tank is discharged along the liquid outlet when the airbag shrinks; the control host sends the collected monitoring air pressure reading and pH value data to the outside world; By applying the method of the present application, not only can the vomiting reflex be directly monitored, but also the vomiting reflex monitoring and the pH value monitoring are integrated into one device. The pH value monitoring also directly monitors the esophageal reflux. When the pH value monitoring is performed, the patient's position changes from lying on the side to lying flat, and the pH detection head can be automatically adjusted by the adaptive movement of the pH detection head in the slide rail. The effusion tank can gather the reflux at the inner bottom of the effusion tank for the pH detection head to detect, thereby improving the detection reliability. The contraction of the airbag is also used to discharge the reflux, so as to facilitate the next pH monitoring and ensure the continuity of the monitoring. The overall structure is reasonable and compact, with high integration and small size, and can provide medical staff with reliable vomiting reflex action monitoring results and esophageal reflux monitoring results, so that when there is a risk of aspiration, they can respond immediately to provide protection for the patient's personal safety. In addition, the cannula of the present application can also be nested in the intubated trachea for real-time monitoring of the esophageal reflux and vomiting reflex of patients undergoing mechanical ventilation.
