Description
Technical field
The present invention relates to a kind of check valve and the check valve in the application of medical instruments field, particularly a kind of dry type drainage
Valve and negative pressure drainage device.
Background technology
It under a closed chamber, health condition is in negative pressure state that human body pleural cavity, which is, Thoracic Organs is kept normal work(
Energy.The a variety of causes such as every wound, traffic accident, compound thoracic injury and pneumothorax operation cause pleural cavity lesion ruptures, will lead
Cause gas or liquid to enter pleural cavity, cause original negative pressure to be changed into malleation, cause atelectasis, heart to indulge diaphragm displacement and trigger the heart
Lung failure.Need to make pleural cavity recover original the gas or liquid drain that enter pleural cavity by drainage system during treatment
Negative pressure state and cardiopulmonary normal function.
Therefore, someone devises a kind of enclosed negative pressure drainage water sealing bottle.It includes fluid collection chamber, water seal cavity, pressure regulating cavity.It is described
Fluid collection chamber on connect by drainage tube, the drainage tube is connected with pleural cavity.Described fluid collection chamber be also connected with by connecting tube one fall U
The depth of the insertion liquid of the U-tube of liquid in one end of type pipe, the other end insertion water seal cavity of the U-tube, insertion water seal cavity
Usually h.In order to prevent backflowing, the h can set the height that must try one's best.
But, we have been found that in actual use, to ensure that water seal can not be kept after certain reason produces suck-back, be led to
Often h can be set higher, once so suck-back still has the ability to keep water seal state.But also therefore, add patient's discharge
The pressure of gas is larger, and patient is weak due to comparison itself, and itself is it is difficult to which mode with strong mode or deliberately goes row
Go out these gases, thus will result in the slow situation of recovery.Even if cough, also easily causes and has an intense pain reluctantly, but also can
Other bad problems can be caused.
The content of the invention
It is an object of the invention to provide a kind of dry type drain valve and negative pressure drainage device, exist for above-mentioned prior art
Deficiency, the device can make patient more easily discharge residual gas, not result in pain during row pressure, simultaneously because going
The sealing structure for water of original negative pressure drainage device is fallen, it helps reduce the volume of negative pressure drainage device.And it is upper faster in use
Victory is convenient, is suitable for war preparedness, first aid etc. and lacks urgent rescue under the occasion at water source.
To achieve these goals, the technical solution adopted in the present invention is：
A kind of dry type drain valve, it is characterised in that：It includes a valve body, and the valve body has air inlet and the exhaust of connection valve pocket
Mouthful；There is the reaction diaphragm that can be deformed according to gas pressure in the valve pocket；Close to the inner surface of air inlet one end in the valve pocket
In smooth structure wide at the top and narrow at the bottom.
Described dry type drain valve, it is characterised in that：On the inside of exhaust outlet one end it is turbine groove pattern in the valve pocket
Pyramidal projections.
Its advantage contributes to the steady discharge exhaust outlet of gas and makes gas stepless action on reaction diaphragm.
Described dry type drain valve, it is characterised in that：The external diameter of the reaction diaphragm is less than the internal diameter of valve pocket.
Described dry type drain valve, it is characterised in that：The valve body is combined by two half-unit to be constituted, and is had in one of half portion
There is air inlet, there is exhaust outlet in another half portion.
Described dry type drain valve, it is characterised in that：The pyramidal projections of the turbine groove pattern are in diverging shape by some
The turbine wheel of distribution is constituted；High, two ends are low in the middle of every turbine wheel, and its tip height is 0.5mm ~ 2.5mm, its outer face and water
The angle of plane is 30 degree ~ 70 degree, and its inner face is from top to exhaust outlet direction arc-shaped transition.
Described dry type drain valve, it is characterised in that：The reaction diaphragm is made up of flexible material, and its hardness is from Shao's formula 5
~ 75 degree of degree, thickness are from 0.5mm ~ 2.5mm.
Described dry type drain valve, it is characterised in that：The reaction diaphragm is made of rubber or silica type material.
A kind of negative pressure drainage device, it includes the fluid collection chamber being connected by drainage tube with patient's pleural cavity；It is characterized in that：
The negative pressure drainage device is provided with dry type drain valve as described above on the shell of fluid collection chamber；The air inlet of the dry type drain valve
Connected with fluid collection chamber, exhaust outlet is towards outside shell.
After said structure, the invention has the advantages that compared with the prior art,：
1st, the present invention is using in negative pressure drainage device, because the pressure of fluid collection chamber generally has with outside in a state of use
" pressure differential ", therefore, in valve pocket there is the reaction diaphragm that can be deformed according to gas pressure can be in by valve pocket inner surface
Smooth structure wide at the top and narrow at the bottom（Such as：Smooth inverted cone-shaped structure）To close or open air inlet.When patient discharges fluid collection chamber
During gas, this usual process is autonomous generation, and reaction diaphragm forms the passage that intracavity gas are gone out, when " pressure by Light deformation
Power is poor " it is to be oriented to from inside to outside, now gas is just gone out by drainage；When " pressure differential " is reverse, reaction diaphragm is in momentary recovery
It is smooth, the gas passage set up originally is closed, allows extraneous gas to enter intracavitary.The activity that the device passes through reaction diaphragm
Unidirectional drainage purpose is completed with valve body structure.It with it is original need to overcome the mode that hydraulic pressure is exhausted in water seal cavity compared with,
It is more laborsaving, mitigate pain during patient's exhaust.
2nd, the present invention can be directly installed on shell of the negative pressure drainage device in fluid collection chamber using in negative pressure drainage device
On, therefore the water seal cavity of original negative pressure drainage device can save, and be conducive to the miniaturization of device.More mainly be beneficial to carry and
Use when under quick rescue, battlefield surroundings, ambulatory environment without water source.
