Example 1
As shown in fig. 1, a novel drainage bag comprises a bag body 1, an input conduit 2, a one-way valve 3, a drain valve 4 and an exhaust valve 5, wherein one end of the bag body 1 is connected with the input conduit 2, the input conduit 2 is connected with the one-way valve 3, the one-way valve 3 comprises an external plastic main body 17 and an internal valve body 18, the internal valve body 18 comprises but is not limited to a diaphragm valve body 18, a ball valve body 18 and the like, the diaphragm valve body 18 consists of an elastic film, and after fluid enters from one side of the plastic main body 17, the film is pushed open to open the valve to allow the fluid to pass through. When the fluid passes through in the opposite direction, the film can seal the valve to prevent the fluid from flowing backwards, and the check valve 3 can prevent the liquid accumulation and the air from flowing backwards. Two ends of the plastic main body 17 are connected with conical joints 19, one end of the conical joint 19 is connected with the input catheter 2, and the other end of the conical joint 19 is connected with a corresponding drainage system. The conical connector 19 can be compatible with drainage tubes of different specifications, so that the flexibility of the one-way valve 3 is improved.
The bag body 1 one end is connected with flowing back valve 4, after the inside sufficient dirty liquid of receiving of bag body 1, discharges from flowing back valve 4, still is connected with discharge valve 5 on the bag body 1, and discharge valve 5 is connected on the bag body 1 and is close to one side of input pipe 2, and the inside of discharge valve 5 is equipped with ventilative waterproof membrane 6, and ventilative waterproof membrane 6 is acrylic acid copolymer membrane material, has good one-way ventilative, isolated liquid's effect, consequently when the gas in with the drainage bag lasts the discharge, can also avoid the liquid to flow out.
Referring to fig. 2-3, the exhaust valve 5 includes a valve tube 7, a first valve cavity 8 and a second valve cavity 9 are disposed in the valve tube 7, the diameter of the first valve cavity 8 is smaller than that of the second valve cavity 9, a ring 10 is disposed below the inner side of the second valve cavity 9, the breathable waterproof membrane 6 is connected to the ring 10, the ring 10 functions like a bracket, the inner side surface of the first valve cavity 8 protrudes from the inner side surface of the second valve cavity 9 because the diameter of the first valve cavity 8 is smaller than that of the second valve cavity 9, a ring table structure 21 is formed above the first valve cavity 8, that is, below the second valve cavity 9, the ring 10 has a size corresponding to that of the ring table structure 21, and the outer diameter of the ring 10 is smaller than or equal to that of the second valve cavity 9, and the diameter of the ring 10 is larger than that of the first valve cavity 8. Thereby enabling the collar 10 to rest on the land structure 21. The gas in the drainage bag is discharged from the second valve cavity 9 through the breathable waterproof membrane 6 on the ring 10 and the first valve cavity 8. The bottom of the ring 10 may be provided with a sealing structure such as a gasket, etc. to enhance the sealing effect of the edge of the ring 10 in a normal state.
The outside of valve pipe 7 is equipped with recess 11, is equipped with through-hole 12 on the recess 11, and through-hole 12 and second valve pocket 9 bottom intercommunication, and the side of ring 10 is equipped with connecting rod 13, and connecting rod 13 passes through-hole 12 and is connected with switch board 14. The valve tube 7 is made of soft elastic materials such as rubber or silica gel, and in a normal state, due to the limiting effect of the connecting rod 13 and the switch plate 14, the ring 10, the connecting rod 13 and the switch plate 14 are all in a horizontal state, and are vertically arranged relative to the valve tube 7, and the ring 10 can be stably arranged on the ring table structure 21, so that gas passes through and liquid is prevented from overflowing. However, when the drainage bag is inflated by too much air in the drainage bag, one side of the ring 10 can be tilted by the connecting rod 13 by pressing the switch plate 14 downward, as shown in fig. 3. The valve tube 7 is made of soft elastic materials such as rubber or silica gel, and the through hole 12 has certain elasticity, so that the ring 10 and the breathable waterproof membrane 6 on the ring 10 can be tilted when the switch board 14 is pressed, and a breathable channel can be formed after the ring 10 is tilted so as to temporarily discharge a large amount of gas.
In the second valve chamber 9, there is provided a monitoring sphere 16, the diameter of which is far smaller than that of the second valve chamber 9, such as a foam ball, etc., and the gas circulation condition is judged by observing the position of the small ball after the switch plate 14 is pressed, if the position of the small ball does not change, no gas is proved to pass, and if the distance between the positions of the small ball changes greatly, a large amount of gas is proved to pass.
The pressure sensor 15 is arranged on the bag body 1, the pressure sensor 15 is a pressure membrane sensor, the pressure of gas in the bag body 1 can be monitored through the pressure sensor 15, when the pressure of the gas in the drainage bag is overlarge, the expansion of the drainage bag is caused, information is transmitted to a guardian through the pressure sensor 15, and the guardian presses the switch plate 14 to release the gas timely.
When the drainage bag is used, firstly, the accumulated liquid and air in the chest cavity are drained to the drainage bag through the input catheter 2 and the one-way valve 3 on the drainage bag, and then the accumulated liquid and the air are led into the drainage bag. Through being equipped with discharge valve 5, can be with the gaseous discharge in the drainage bag, avoid the gaseous collision in the drainage bag, reduce the effect of drainage and the risk of infection, simultaneously, be equipped with ventilative liquid film of preventing in the discharge valve 5, have unidirectional ventilative, the effect of isolated liquid can avoid the liquid in the drainage bag to overflow from discharge valve 5.
When the gas in the drainage bag is excessive, only through ventilative liquid proof membrane can't discharge fast, through pressing down switch board 14, can drive ventilative one end perk of liquid proof membrane, the gaseous quick release in the drainage bag of being convenient for. The embodiment is simple and convenient to operate, and reduces the working pressure of medical staff.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
