Problems solved by technology

Therefore, installation space is required since the device cannot be made compact
Moreover, since water must be added to both the water seal part 25 and the chest cavity negative pressure control part 33, there is a shortcoming of inconvenient operation.

Embodiment Construction

[0016] Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. In addition, when describing the embodiments of the present invention, for the sake of convenience, the same reference numerals are assigned to the same parts as those of the above-mentioned conventional embodiments, and overlapping descriptions will be omitted.

[0017] exist Figure 1 to Figure 6 In the shown first embodiment, X is a medical low-pressure suction discharge device made of transparent or translucent synthetic resin for discharging liquid and gas from a body cavity such as the chest of a human body. If the low-pressure suction discharge device X is combined with Figure 14 Compared with the existing embodiment shown, the low-pressure suction and discharge device X is different in that the water seal part and the chest cavity negative pressure control part are integrated (shared with one water W2), and other basic principles are the same, so The wate...

Abstract

The invention aims to provide a medical low-pressure suction discharging device which is compact and more easily used and operated and can prevent hybrid bacteria from invading when atmosphere reversely flow to the side of a collection chamber from a water seal part and thoracic cavity negative pressure control part. The medical low-pressure suction discharging device consists of a suction pressure regulating part, the water seal part and thoracic cavity negative pressure control part, and a liquid discharge quantity measuring part, wherein a second hanging partition wall of which the lower end is provided with an opening, and a dividing wall are respectively formed on the water seal part and thoracic cavity negative pressure control part; by forming the second hanging partition wall and the dividing wall, a first chamber, a second chamber and a third chamber are respectively formed and can jointly accommodate water for preventing air from reversely flowing to the thoracic cavity of a patient from the atmosphere and making negative pressure in the thoracic cavity of the patient close to set suction pressure in the lower part; in addition, a float embedded into a circulating hole of a float barrier wall is arranged on the water seal part and thoracic cavity negative pressure control part.

Description

technical field [0001] The present invention relates to a low-pressure suction and discharge device for medical use, in particular to a low-pressure suction and discharge device for medical use for discharging liquid and gas from body cavities such as the chest of a human body. Background technique [0002] Conventionally, there is an example described in Japanese Utility Model Publication No. 4-22750 as such a low-pressure suction and discharge device for medical use. [0003] This low-pressure suction and discharge device (directly use the reference numerals described in the above publication) Y is composed of the following components: a suction pressure regulator 20 having a pressure gauge chamber 22 partitioned by a first hanging partition wall 23; a water seal 25, It has a first water-sealed chamber 26 that communicates with the suction pressure regulator in a gas-permeable manner and is separated by a second hanging partition wall 27; The collection chamber 31 that th...
