Problems solved by technology

[0006] The vacuum pump makes the negative pressure in the receiver use the catheter to make the negative pressure in the chest cavity consistent with that in the receiver. When the patient inhales, the chest cavity increases, making the negative pressure in the chest cavity and the consistency of the receiver decrease. This allows the lungs to over-expand, posing a risk to the patient

Embodiment Construction

[0035] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as Figure 1 to Figure 4 As shown, the embodiment of the present invention discloses a chest cavity 100 closed drainage device in the department of respiratory care, including: a receiver 10 , a vacuum pump 20 , a catheter 40 and a pressure coordination mechanism 30 . The receiver 10 is used to contain the effusion in the chest cavity 100; the vacuum pump 20 forms a certain degree of vacuum in the receiver 10 by vacuuming; one end of the catheter 40 extends into the receiver 10, and the other end extends into the chest cavity 100 to The effusion is guided into the receiver 10; the pressure coordinating mechanism 30 is used to compensate the pressure in the receiver 10 when the patient performs an inhalation action, so...

Abstract

The invention discloses a thoracic closed drainage device in respiratory nursing department, which comprises: a receiver, which is used to hold the effusion in the chest cavity; a vacuum pump, which forms a certain vacuum degree in the receiver by vacuuming; a catheter, which One end protrudes into the receiver, and the other end extends into the chest cavity to guide the effusion into the receiver; a pressure coordination mechanism, which is used to inject pressure into the receiver when the patient performs an inhalation action Medium compensation pressure to reduce the reduction of negative pressure. When the patient performs an inhalation action, the volume of the thoracic cavity increases, making the negative pressure in the thoracic cavity increase. The degree of change in the negative pressure level is small, or the degree of increase is reduced, thereby preventing the lung from overexpanding during the initial period of drainage during inspiration.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drainage device for chest drainage. Background technique [0002] As a medical term, the thorax is the cavity between the lungs and the rib cage. When for some reason, there will be fluid in the chest cavity, and the fluid needs to be drained. The process of draining the fluid is called drainage. [0003] The device used to drain the effusion is called the gravity device. The drainage device in the prior art includes a liquid container, a vacuum pump for drawing a vacuum into the container, and a catheter with one end connected to the container and the other end extending into the chest cavity. . Under the action of vacuuming by the vacuum pump, a negative pressure is formed in the receiver, thereby guiding the effusion in the chest cavity to flow into the receiver through the catheter. [0004] It should be explained that whether a person is in the state of inhalati...
