Detailed Description

The following description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention, and the present invention is further described with reference to the accompanying drawings and embodiments.

Example, see figure 1:

a quantitative respirator for locating pulmonary nodules comprises a sleeve 1, a piston 2, a spring 3 and an air suction pipe 4.

The sleeve 1 is a cylinder structure, a lower end opening of the sleeve is sealed and covered with a lower end plate, an upper end opening of the sleeve is covered with an upper end plate, the upper end plate is provided with a plurality of ventilation holes 10, the upper end plate is used for limiting the piston 2, and the ventilation holes 10 are used for circulating air at the upper end of the piston 2 and air outside the sleeve 1.

The piston 2 is a cylinder structure, the outer circumferential surface of the piston is matched with the inner wall of the sleeve 1, the piston 2 slides in the sleeve 1 in a sealing mode, an air suction cavity 5 is formed in the sleeve 1, the air suction cavity 5 is a sealed cavity, and if air in the air suction cavity is reduced, the piston 2 moves downwards under the action of air pressure.

The spring 3 is positioned in the air suction cavity 5 and is fixedly arranged between the piston 2 and the sleeve 1, and the piston 2 is abutted against the upper end plate of the sleeve 1 under the pushing of the spring 3, so that the supplement of air in the air suction cavity 5 is realized, and the fixed air quantity in the air suction cavity 5 is ensured.

Breathing pipe 4 fixed mounting is on sleeve pipe 1, and its and the chamber 5 intercommunication of breathing in, and the one end tip fixed mounting who keeps away from the chamber 5 of breathing in on breathing pipe 4 has air cock 11, can be convenient for breathing in of breathing pipe 4 through air cock 11, avoids appearing the gas leakage problem.

An air suction one-way valve 8 is fixedly installed at one end, close to the air suction cavity 5, of the air suction pipe 4, the conduction direction of the air suction one-way valve 8 faces the air suction pipe 4 from the air suction cavity 5, and the air suction one-way valve 8 can prevent air in the air suction pipe 4 from entering the air suction cavity 5.

An expiration pipe 6 is fixedly installed at one end, far away from the inspiration cavity 5, of the inspiration pipe 4, an expiration one-way valve 7 is fixedly installed on the expiration pipe 6, the conduction direction of the expiration one-way valve 7 faces the expiration pipe 6 from the inspiration pipe 4, and the expiration one-way valve 7 can prevent air in the expiration pipe 6 from entering the inspiration pipe 4.

When a patient exhales through the inhalation tube 4, exhaled air is exhausted through the exhalation tube 6, and when the patient inhales through the inhalation tube 4, air in the inhalation cavity 5 is inhaled by the patient, so that a fixed air volume is inhaled into the lung of the patient.

An air compensating valve 9 is fixedly installed on the air suction cavity 5, the air compensating valve 9 adopts an electric switch valve, the input end of the electric switch valve is connected with the output end of the PLC, a flow switch is fixedly installed at one end, far away from the air suction pipe 4, of the air exhaust pipe 6, and the output end of the flow switch is connected with the input end of the PLC, so that linkage of the air compensating valve 9 and the air exhaust one-way valve 7 is realized.

The flow switch converts an air flow signal in the expiration pipe 6 into an electric signal and sends the electric signal to the PLC controller, the PLC controller sends an opening signal to the air compensating valve 9 to open and close the air compensating valve 9 in a delayed mode, so that air compensation in the inspiration cavity 5 is realized under the action of the spring 3, and when no air is exhausted from the expiration pipe 6, the air compensating valve 9 is closed to ensure that the air completely comes from the inspiration cavity 5 when a patient inhales through the inspiration pipe 4.

The breathing pipe 4 and the expiration pipe 6 are threaded hoses, so that the positions can be flexibly adjusted, and the use is more convenient.

When specifically using, the patient exhales through 4 efforts of breathing pipe, arrange to the greatest extent until lung air, then breathe in hard through breathing pipe 4, then stop when inhaling immobility, can carry out the radio frequency ablation operation this moment can, wherein, the patient exhales the back, the volume of chamber 5 of breathing in reaches the biggest under spring 3's effect, the patient breathes in the back, the volume of chamber 5 of breathing in reaches the minimum, and spring 3 is compressed completely, this kind of mode can guarantee that the patient inhales quantitative air, the inflation degree that makes the patient lung maintains invariable, the position fixation of the relative lung tunica adventitia of pulmonary nodule, and then promote efficiency and the accuracy that the pulmonary nodule was fixed a position, realize accurate efficient pulmonary nodule excision or melt the operation.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
