Oral foreign body negative pressure suction equipment and usage method thereof

Abstract

The invention discloses oral foreign body negative pressure suction equipment and a usage method thereof. The oral foreign body negative pressure suction equipment comprises an esophagus, a suction head and a negative pressure device. The suction head is connected with the left end of the esophagus, the negative pressure device is connected with the right side of the esophagus, the negative pressure device comprises a power box, a pumping cylinder, a first tee joint, a second tee joint, a reciprocating screw rod, a piston block, a shaft rod and a motor, a liquid medicine cylinder is fixedly connected to a bottom plate of the suction head, and a piston plate is slidably connected into the liquid medicine cylinder. The suction head is arranged on the esophagus or the portion, needing sputum suction, of the oral cavity of a patient, negative pressure generated by the negative pressure device acts on the esophagus, so that sputum at the sputum accumulation position is sucked out, the negative pressure device can generate continuous negative pressure, continuous suction of the sputum can be achieved, the sputum suction effect is improved, and meanwhile the suction head is convenient to use. When the sputum is difficult to suck out smoothly due to high sputum concentration, the dissolved medicine in the liquid medicine cylinder is discharged and acts on the sputum accumulation position to dissolve the accumulated sputum, so that the sputum can be sucked out smoothly.

Description

technical field [0001] The invention relates to the technical field of clinical nursing equipment, in particular to an oral cavity foreign body negative pressure suction equipment and a method for using the same. Background technique [0002] Severely ill patients are generally accompanied by respiratory insufficiency. When the hospital is caring for intensive care patients, it is necessary to provide respiratory management and respiratory support for critically ill patients. The most common method is to use a ventilator to provide oxygen supply care for patients, but breathing When the machine is working, the patient’s airway is required to be unobstructed. When a critically ill patient is in a coma, the mouth and esophagus will still secrete sputum spontaneously. Because the critically ill patient cannot actively control the oral muscles to discharge the sputum, the esophagus and oral cavity will be sputum. A large amount of sputum is accumulated, which must be discharged ...

Problems solved by technology

[0002] Severely ill patients are generally accompanied by respiratory insufficiency. When the hospital is caring for intensive care patients, it is necessary to provide respiratory management and respiratory support for critically ill patients. The most common method is to use a ventilator to provide oxygen supply care for patients, but breathing When the machine is working, the patient’s airway is required to be unobstructed. When a critically ill patient is in a coma, the mouth and esophagus will still secrete sputum spontaneously. Because the critically ill patient cannot actively control the oral muscles to discharge the sputum, the esophagus and oral cavity will be sputum. Accumulation of a large amount of sputum, which must be discharged in time

[0003] Generally speaking, the sputum in the esophagus and oral cavity is sucked out through the negative pressure generated by the negative pressure suction device, while the negative pressure suction device in the prior art is usually an air bag, and the negative pressure generated by squeezing the air pressure is used to suck out the sputum, while The airbag generates negative pressure through continuous extrusion and elastic recovery, resulting in intermittent negative pressure generation, resulting in the inability to achieve continuous suction operation and poor sputum suction effect

[0004] And the esophagus connected to the balloon extends into the suction position. When the concentration of sputum in the suction position is high, it may cause blockage of the esophagus, resulting in the inability to suck out the sputum smoothly.
