Problems solved by technology

Critically ill patients are usually combined with abnormal respiratory and circulatory function, peripheral tissue hypoperfusion or increased peripheral vascular resistance, and oxygenation is significantly reduced. If not detected and corrected in time, it will seriously affect the patient's prognosis

Embodiment 1

[0029] Such as figure 1 As shown, the multifunctional gastric tube with blood oxygen saturation monitoring function disclosed in this embodiment includes a tube body, an oxygen saturation sensor 4, and a gastric juice pumping channel 1 and a nutrient solution delivery channel that are isolated from each other in the tube body 2. The oxygen saturation sensor 4 is embedded on the outer wall of the tube body. The data line of the oxygen saturation sensor 4 passes through the tube body and is connected with an external plug, and the external plug transmits the oxygen saturation signal output by the data line to the computer terminal for correction and display. If the alarm limit is reached, the alarm will be called immediately;

[0030] Further, such as figure 1 , 2 , 3, the oxygen saturation sensor 4 is covered with a protective film 5, and a water inlet channel 6 is also provided in the tube body, and the water inlet channel 6 is isolated from the gastric juice pumping channe...

Embodiment 2

[0034] Such as Figure 5 , 6 , 7, the difference between this embodiment and embodiment 1 is that the protective film 5 is arranged around the pipe body in a circle, and an annular cavity 10 is arranged in the side wall of the pipe body, and the annular cavity 10 is coaxially arranged with the pipe body , the water inlet passage 6 communicates with the annular cavity 10 , and the drainage holes 7 are arranged on the outer wall of the annular cavity 10 , and at least two drainage holes 7 are arranged at intervals along the annular cavity 10 . Preferably, the drain holes 7 are arranged at equal intervals along the annular cavity 10 , and the water discharged from the drain holes 7 flushes the entire protective film 5 .

Embodiment 3

[0036] Such as Figure 8 As shown, the difference between this embodiment and embodiment 1 or embodiment 2 is that: the wire channel 3 is a solid tube, and the data line and the water inlet channel 6 are buried in the wire channel 3 .

[0037] In the present invention, the oxygen saturation sensor adopts the principle of reflective pulse oximetry to monitor blood oxygen saturation, and the oxygen saturation sensor is inserted into the lower esophagus through a gastric tube, continuously monitors and evaluates the pulse oxygen saturation of the descending aorta, and monitors the central part of the body oxygen saturation. No matter whether the circulatory function is abnormal or not, and whether it is accompanied by peripheral hypoperfusion, the pulsation of the aorta is strong (except in the CPR state), and it is obviously stronger than that of the peripheral arteries. The descending aortic pulse oxygen saturation monitored by the gastric tube through the esophagus is consist...

Abstract

The invention discloses a multi-functional stomach tube concurrently having a blood oxygen saturation monitoring function. The multi-functional stomach tube comprises a tube body, an oxygen saturation sensor, a gastric juice pumping drainage channel and a nutrient solution delivery channel, wherein the gastric juice pumping drainage channel and the nutrient solution delivery channel are mutually isolated in the tube body; the oxygen saturation sensor is embedded in the outer wall of the tube body. The multi-functional stomach tube disclosed by the invention is simple in structure and convenient to operate, can be used for not only providing enteral nutrition treatment and gastrointestinal decompressing treatment, but also reducing the pulse oxygen saturation of aortas through continuous monitoring and evaluating of esophagi, and is used for monitoring the oxygen saturation of the center part of a body, assisting in dynamically and accurately evaluating the respiratory and circulatory function of a critical patient, guiding respiratory and circulatory supportive treatment, cleaning a protective film of the oxygen saturation sensor, and guaranteeing the accuracy of monitoring data.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multifunctional gastric tube with the function of monitoring blood oxygen saturation. Background technique [0002] The currently clinically applied gastric tube can input nutrient solution and attract gastrointestinal fluid to decompress the gastrointestinal tract and prevent gastrointestinal distension. However, for critically ill patients, continuous monitoring of respiratory function is very important, and peripheral pulse oximetry (oxygen saturation), as a means of non-invasive continuous monitoring of oxygenation, has so far been an important part of vital sign monitoring. Critically ill patients are usually complicated with abnormal respiratory and circulatory function, peripheral tissue hypoperfusion or increased peripheral vascular resistance, and significantly reduced oxygenation. If not detected and corrected in time, the prognosis of the patient will be seri...
