Description
This utility model belongs to a kind of medical apparatus and instruments, be applicable to pneumothorax, the hemopneumothorax that the various thoracic traumas of performing the operation back and a variety of causes of torso model cause and make closed drainage of pleural cavity by spontaneous pneumothorax, the hemopneumothorax of internal medicine, the gas and the liquid drain that enter from the external world in the thoracic cavity or self produce are come out, impel atelectasis, thereby the thoracic cavity becomes negative pressure again, recovers the function of breath cycle.
The vial that our country adopted is as drainage container at present, and flow liquid and negative pressure chamber carry out work in same vial.It does not have independently negative pressure chamber, needs manual power assisting to produce negative pressure, and negative pressure is insufficient easily, and the drain successfully of the intravital waste gas of people is come out, and easily generation is breathed one's last.The liquid that comes out of drain can not separate with water seal liquid in addition, causes difficulty to observation.Although the disposable closed thoracic vacuum suction of the first generation of developing recently water-sealed drainage bottle has solved the problems referred to above, thoroughly do not solve gas-liquid refluence phenomenon yet.This phenomenon is then influence observation gently, and is heavy then form open pneumothorax, even causes the pulmonary collapse, the severe complication of pendular movement of mediastinum and even death.
The purpose of this utility model provides a kind of disposable adjustable negative pressure, be convenient to observe, prevent the hemopneumothorax thoracic duction instrument that pours in down a chimney.This device can be regulated the liquid level height of negative pressure bottle according to the hemopneumothorax intrathoracic pressure, obtains required negative pressure.
Shown in attached Fig. 1 and 2, this utility model is taken over (5), water-sealed drainage bottle (6), negative pressure adjustable pipe (7), negative pressure bottle (8) and bottle cap (9) by splanchnocoel drainage tube (1), hydrops bottle (2), vacuum suction pipe (3), charger (4), suction pump and is formed.Hydrops bottle (2) water-sealed drainage bottle (6) negative pressure bottle (8) is respectively three containers.Hydrops bottle (2) is linked to each other by vacuum suction pipe (3) with water-sealed drainage bottle (6), and vacuum suction pipe (3) is inserted into water-sealed drainage bottle (6) upper end partly check valve (10) is housed.Water-sealed drainage bottle (6) is connected with the breather (11) of negative pressure bottle (8) by top.In bottle, the upper end is a filling opening to negative pressure adjustable pipe (7) by the upper end cover straight cutting of negative pressure bottle, opens wide logical atmosphere.Suction pump is taken over (5) and is picked out another termination suction pump from the negative pressure bottle upper end cover.Intrathoracic drain (1) one end inserts splanchnocoel, another termination hydrops bottle.Filling opening (4) on water-sealed drainage bottle (6) end cap seals with lid behind liquid feeding.Whole like this device is taken over (5) and is constituted head and the tail vacuum suction drainage channel from splanchnocoel drainage tube (1) to suction pump.Above-mentioned all parts all are to be that raw material is made by plastics, have two dividing plates that the hydrops bottle is divided into A, B, three parts of C in the hydrops bottle.
The operation principle of this device:
(1) water-stop of negative pressure space
Water-sealed drainage bottle (6) and negative pressure bottle (8) are equipped with the Sterile Saline of certain altitude respectively, vacuum suction pipe (3) and negative pressure adjustable pipe (7) in its bottle are inserted into respectively under each bottle liquid level, and two bottles of liquid level tops constitute the water seal negative pressure space by breather (11).This spatial gas has three access ways, and the filling opening (4) of first negative pressure adjustable pipe leads to atmosphere, and it two is that the vacuum suction pipe communicates with splanchnocoel through drainage tube and hydrops bottle, and it three is to lead to suction pump.Preceding two passages are owing to water seal, gas only import but no export.Third channel is because suction pump effect gas only export but no import.
(2) generation of negative pressure, keep and regulate
During suction pump work, negative pressure space gas is taken away air pressure decline and is caused negative pressure.Fluid column is owing to the atmospheric pressure effect descends in the negative pressure adjustable pipe.Increase along with negative pressure value, the difference of the pressure of atmospheric pressure and negative pressure space also increases, fluid column continues to descend, it is fair to drop to pipe port up to fluid column, ambient atmosphere bloats liquid level by the liquid in the negative pressure bottle, enters negative pressure space, even at this moment suction pump works on, the pressure of gas no longer reduces in the negative pressure space, and negative pressure value remains unchanged.What in fact this moment, suction pump was taken out is to bloat the atmosphere that liquid level replenishes into.Pressure difference in atmospheric pressure and the negative pressure space equals the fluid column height that adjustable pipe reaches the degree of depth under the liquid level.This difference is exactly the negative pressure value of negative pressure space.So to reach the subsurface degree of depth certain when adjustable pipe, then the negative pressure value of negative pressure space is also certain, and equals the water column height that pipe reaches the degree of depth under the liquid level.So just can regulate adjustable pipe and reach the subsurface degree of depth, just the liquid level of the liquid by pouring into negative pressure bottle is regulated the required negative pressure value of negative pressure space.
(3) drain of liquid, gas
As long as the thoracic cavity wants the draining fluids liquid level to be higher than hydrops position that bottle is put, liquid just with the deadweight of itself, flows in the hydrops bottle by drainage tube automatically so.Two dividing plates of hydrops bottle (2) are divided into three every A, B, C with bottle.When flow of liquid completely flows to B behind the A gradually, after also flowing completely, B just flows to C.At any time read liquid drain situation more exactly from bottle wall scale like this.
Splanchnocoel constitutes air pressure cavity (ignoring the resistance of gas in flow process) such as through drainage tube, hydrops bottle to the liquid level of vacuum suction liquid in pipe.Along with the carrying out of lung respiratory movement, the air pressure in the pleural space periodically changes, vacuum suction intraluminal fluid post also moves up and down thereupon.When thoracic cavity air pressure respectively greater than, equal, during less than the negative pressure value of water-sealed drainage bottle (water-sealed drainage bottle communicate atmospheric pressure value equate) with negative pressure bottle, the fluid column face in the vacuum suction pipe also is lower than, equals, is higher than the outer liquid level of pipe respectively.In case the air pressure in thoracic cavity and the draught head of water-sealed drainage bottle stretch into the water column of level when high more than or equal to suction catheter, the gas in thoracic cavity just attracted in the negative pressure bottle.The difference in height of suction catheter bottom and liquid level is more little, and the gas in thoracic cavity is just easy more to be attracted out.We can infer intrathoracic air pressure according to the drain situation of gas-liquid like this, thereby by regulating the negative pressure bottle vacuum magnitude, make intrathoracic gas successfully attract out.
(4) prevent pouring in down a chimney of liquid:
To first generation vacuum suction water-sealed drainage bottle, when the difference of negative pressure bottle internal gas pressure and intrathoracic pressure greater than the vacuum suction pipe when the water column of water-sealed drainage bottle one side height is high, the liquid of water-sealed drainage bottle will be pressed to the hydrops bottle by suction catheter, cause in the hydrops bottle to change because of the water that has mixed in the water-sealed drainage bottle influence observation by the amount of liquid of drawing in the thoracic cavity and color, concentration etc.The more important thing is that liquid reduces because of suck-back in the water-sealed drainage bottle, make former being positioned under the horizontal plane, exposed by the mouth of pipe that water sealed, cause the thoracic cavity directly to communicate with outside air, be so-called iatrogenic open pneumothorax, even cause patient's pulmonary collapse, pendular movement of mediastinum and even dead severe complication.First generation vacuum suction water-sealed drainage bottle is by longer, stands in space high negative suction catheter and prevents what this liquid from pouring in down a chimney.But the suction catheter that plastics the are done deliquescing of Yin Wendu rising sometimes and lie down to get off to cause highly greatly and reduce in patient's cough, when dark air-breathing or intrathoracic cavity is big, tends to occur the above-mentioned this phenomenon of pouring in down a chimney.This in addition prolongation suction catheter length way has not only been wasted material but also be not easy to operation.Designed one-way cock (10) in view of the foregoing, placed on the upper end pipeline that is inserted into vacuum suction pipe in the water-sealed drainage bottle as Fig. 3.Guarantee that gas can only be by the hydrops bottle to water-sealed drainage bottle (in promptly by the thoracic cavity to the external world) one-way trip.As long as intrathoracic pressure is higher than atmospheric pressure or constant lasting negative pressure, intrathoracic gas discharges after can unimpededly entering in the water-sealed drainage bottle; Otherwise reverse water column can make valve closing.
Such modified model is the device safety and reliability of second filial generation vacuum suction water-sealed drainage bottle, meets the needs of thoracic cavity physiology, guarantees intrathoracic gas-liquid only export but no import, is beneficial to the multiple of lung and opens, and avoids the generation of iatrogenic pneumothorax.
Comprehensive above-mentioned apparatus structure and principle Analysis, the good effect that this utility model compared with prior art has is: 1, two containers of the used water seal liquid subpackage of draining fluids and device, not phase blending makes it to observe accurate convenience.2, the whole system negative pressure fully unimpeded adjustable at any time, drain is smooth.3, negative pressure is lasting constant, can not produce in the use and breathe one's last, pours in down a chimney phenomenon, so safe and reliable.4, whole device is all made of non-toxic plastic, and goods are difficult for smashing, and the processing technique simpler production is convenient, cheap.5, because cross infection is avoided in disposable use.
