no. 1 Embodiment approach

[0028] Hereinafter, a first embodiment of the present invention will be described based on the drawings.

[0029] [Structure of intubation]

[0030] figure 1 It is a sectional view showing an attachment example of the cannula 1 of this embodiment.

[0031] Such as figure 1 As shown, the cannula 1 of this embodiment is attached to the hole H that communicates the body surface with the inside of the lung parenchyma L2 of the lung L, and an exhaust port PT is formed as a lumen. Specifically, the cannula 1 is attached to the hole H that passes through the thorax C1, the wall-side pleura C2, the visceral pleura L1 of the lung L, and the lung parenchyma L2, and forms a part (target site) from the part with a large residual volume in the lung parenchyma L2. ) Exhaust port PT for degassing to discharge residual gas out of the body surface. In addition, this hole H is formed avoiding the ribs CS located in the thorax C1. In addition, the hole H is formed at a site where the wall-s...

no. 2 Embodiment approach

[0064] Next, a second embodiment of the present invention will be described.

[0065] The cannula of this embodiment has the same structure as the cannula 1 described above. Here, in this cannula 1 , the screw groove 114 is formed on the outer surface of the main body 11 , and the screw thread 1431 of the pressure regulator 14 is screwed to the screw groove 114 outside the main body 11 . On the other hand, in the cannula of this embodiment, the screw groove is formed on the inner surface of the main body, and the screw thread of the pressure adjustment part is screwed into the screw groove inside the main body. The cannula of this embodiment is different from the cannula 1 described above in this point. In addition, in the following description, the same code|symbol is attached|subjected to the part already demonstrated and the same or substantially the same part, and description is abbreviate|omitted.

no. 3 Embodiment approach

[0083] Next, a third embodiment of the present invention will be described.

[0084] The cannula of the present embodiment is different from the cannula 1 and 2 described above in the configuration for adjusting the diameter of the flow path of air discharged from the cavity L3 to the outside of the body surface. In addition, in the following description, the same code|symbol is attached|subjected to the part already demonstrated and the same or substantially the same part, and description is abbreviate|omitted.

Abstract

Disclosed herein is a tube mounted in a hole that makes a body surface and inside of lung parenchyma communicate with each other, the tube including: a main body portion that has a hole part having one end opened to the inside of the lung parenchyma and the other end opened to outside of the body surface; and a flow rate adjuster that is provided for the main body portion and adjusts a flow rate of air flowing in the hole part.

Description

technical field [0001] The present invention relates to a cannula, and more specifically, to a cannula for degassing installed in a hole that communicates the surface of the body with the inside of the lung. Background technique [0002] Conventionally, COPD (Chronic Obstructive Pulmonary Disease: Chronic Obstructive Pulmonary Disease) is known as an airway progressive disease. In this COPD patient, the alveolar wall of the lung tissue gradually weakens due to weakening and loses elastic resilience, and the lungs are highly inflated so that the residual capacity of the lungs cannot be reduced. As the disease progresses, the expiratory capacity of the lungs and the surface area for air exchange decrease, eventually leading to difficulty breathing. [0003] For patients with such COPD, there is proposed a treatment method of reducing lung residual air by forming lung pores through the lung pores (for example, refer to Document 1: JP 2011-512233 A). [0004] In the treatment ...
