Embodiment Construction

[0014] The following descriptions are only preferred embodiments of the present invention, and do not limit the protection scope of the present invention. The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Examples, see figure 1 Shown:

[0016] A quantitative respirator for lung nodule location, comprising a casing 1, a piston 2, a spring 3 and an inhalation tube 4.

[0017] The casing 1 is a cylindrical structure, the lower port is sealed with a lower end plate, and the upper port is covered with an upper end plate, and a number of ventilation holes 10 are opened on the upper end plate, and the upper end plate is used for the limit of the piston 2. The ventilation hole 10 is used for the communication between the air at the upper end of the piston 2 and the air outside the casing 1.

[0018] The piston 2 is a cylindrical structure, and its outer peripheral surface is adapted to the inner wall of the ...

Abstract

A quantitative respirator for pulmonary nodule positioning disclosed by the present invention is characterized by comprising a sleeve, a piston, a spring and an air suction pipe, wherein the piston slides in the sleeve in a sealed mode, an air suction cavity is formed in the sleeve, and the spring is fixedly installed between the piston and the sleeve and enables the piston to abut against an upper end plate of the sleeve; the air suction pipe is fixedly installed on the sleeve and is communicated with the air suction cavity. Compared with the prior art, the quantitative respirator has the advantages that a patient can inhale quantitative air through the air suction pipe, so that the expansion degree of the lung of a patient is kept constant, the position of a pulmonary nodule relative to a pulmonary envelope is fixed, then the pulmonary nodule positioning efficiency and accuracy are improved, and the accurate and efficient pulmonary nodule excision or ablation operation is realized.

Description

technical field [0001] The invention relates to a device for locating pulmonary nodules, in particular to a quantitative respirator for locating pulmonary nodules. Background technique [0002] With the popularization of lung CT examination, more and more patients with small pulmonary nodules are detected in time. For such patients, surgical resection or thermal ablation after precise positioning of pulmonary nodules is usually required. CT-guided localization of pulmonary nodules. [0003] However, due to the different degrees of expansion of the lungs caused by the change of the respiratory phase of the patient, the position of the pulmonary nodule is constantly changing, resulting in poor positioning accuracy and low efficiency, so it is necessary to improve it. Contents of the invention [0004] The invention provides a quantitative respirator for lung nodule location, which can solve the technical problem that the air inhalation volume of the patient cannot be accura...
