Background

The human pleural cavity is a closed cavity and is in a negative pressure state under the healthy condition, so that organs in the pleural cavity keep normal functions. When the pleural cavity is damaged and broken due to various reasons such as trauma, car accident, composite chest injury, pneumothorax operation and the like, gas or liquid enters the pleural cavity, the original negative pressure is changed into positive pressure, and atelectasis and heart mediastinal displacement are caused to cause cardiopulmonary failure. When in treatment, the air or liquid entering the pleural cavity needs to be drained by the drainage device so that the pleural cavity recovers the original negative pressure state and normal functions of the heart and lung.

Therefore, the inventor applies for a dry drainage valve and a negative pressure drainage device (CN 201710273963.2), namely a dry drainage bottle (short for a dry sealing bottle). The dry drainage bottle is characterized in that a dry drainage valve is arranged on the shell of the hydrops cavity; the air inlet and hydrops intracavity intercommunication of this dry-type drainage valve, the gas vent is outside towards the shell, has consequently saved the water seal chamber of original negative pressure drainage device, is favorable to the miniaturization of device, more mainly does benefit to and carries and quick rescue, use when the anhydrous source under battlefield environment, the first aid environment. Has practical significance and disaster relief significance.

The dry-type flow-guiding valve can also use the structure disclosed in CN201710273963.2, and comprises a valve body, a valve body and a valve body, wherein the valve body is provided with an air inlet and an air outlet which are communicated with a valve cavity; the valve cavity is internally provided with an induction diaphragm which can deform according to the gas pressure; the inner side surface of one end of the valve cavity close to the air inlet is of a smooth structure with a wide upper part and a narrow lower part. The inner side of one end of the valve cavity close to the exhaust port is provided with a conical protrusion in the form of a turbine groove. Its advantages are smooth gas exhaust and uniform action of gas on the sensing diaphragm. The outer diameter of the sensing diaphragm is smaller than the inner diameter of the valve cavity. The valve body is composed of two halves, wherein one half is provided with an air inlet, and the other half is provided with an air outlet. The conical projection in the form of the turbine groove is formed by a plurality of turbine blades distributed in a divergent shape; each turbine blade is high in the middle and low in the two ends, the height of the top end of each turbine blade is 0.5-2.5 mm, the included angle between the outer end face of each turbine blade and the horizontal plane is 30-70 degrees, and the inner end face of each turbine blade is in arc transition from the top end to the exhaust port. The sensing diaphragm is made of soft materials, the hardness of the sensing diaphragm is from Shore 5 degrees to 75 degrees, and the thickness of the sensing diaphragm is from 0.5mm to 2.5 mm. The induction membrane is made of rubber or silica gel materials. Due to the prior art, the using state is not described in detail.

However, from practical use, we find that the indication cavity (or the observation cavity) is lost due to the absence of the water seal cavity, and although the negative pressure drainage effect of the device is not lost, the pressure change and fluctuation in the bottle cannot be observed, and the instantaneous pressure change state of a user cannot be timely read or recorded.
