Embodiment Construction

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-3 As shown, a chest cavity closed drainage device with adjustable suction speed includes a hollow body portion 1, and the body portion 1 is divided into three independent and side-by-side cavities by a first partition 5 and a second partition 6. The three independent chambers are the collection chamber 2, the water seal chamber 3, and the pressure measurement chamber 4. The water seal chamber 3 is located between the collection chamber 2 and the pressure measurement chamber 4, and the top of the collection chamber 2 is connected with a drainage pipe 9 The drainage pipe 9 is provided with a manual speed regulating device 13, an electromagnetic flow regulating valve 14, and a flow detection device. The flow detection device is a flow sensor ...

Abstract

The invention discloses a thoracic cavity closed drainage device capable of adjusting suction speed, and belongs to the field of medical instruments. The device comprises a hollow body part, wherein the body part comprises three independent cavities arranged side by side; the three independent cavities are a collecting chamber, a water sealing chamber and a pressure measuring chamber respectively; the top of the collecting chamber is connected with a drainage tube; the drainage tube is provided with a manual speed regulating device, an electromagnetic flow regulating valve and a flow detecting device; the lower portion of the collecting chamber is communicated with the upper portion of the water sealing chamber through a first connecting tube; the top of the water sealing chamber is communicated with a negative pressure aspirator through a suction tube; the lower portion of the water sealing chamber is communicated with the upper portion of the pressure measuring chamber through a second connecting tube; the top of the pressure measuring chamber is communicated with a negative pressure device through a third connecting tube; and an air pressure sensor is arranged in the pressure measuring chamber. The device further comprises a control device, and the control device is electrically connected with the electromagnetic flow regulating valve, the flow detecting device, the negative pressure aspirator and the negative pressure device. The device has the effect of quickly and automatically adjusting the suction speed.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a chest cavity closed drainage device with adjustable suction speed. Background technique [0002] The traditional closed chest drainage device has indeed solved a large number of hemopneumothorax drainage problems in many years of practical work. It is still widely used in many hospitals, but there are still many shortcomings. For example, the drainage device cannot quickly and autonomously adjust the suction speed, requires manual adjustment, requires experienced medical staff to operate accurately, requires high operators, and is inconvenient to use. [0003] Existing chest cavity closed drainage devices are generally divided into two types, one of which is for example a chest cavity closed drainage device (application number: 201720337412.3), the utility model includes a bag body, a drainage tube, a one-way valve, a flow controller, an L-type The discharge tube and the deep ...
