Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
As shown in fig. 1, 2, 3, 4, 5, 6, and 7: a portable thoracic drainage suit comprises a multi-cavity drainage tube 1, wherein the multi-cavity drainage tube 1 comprises a first drainage cavity 1-1 and a second drainage cavity 1-2 which are used for being placed in a thoracic cavity. A plurality of first drainage openings 1-1-1 of the first drainage cavity 1-1 are arranged at the head part of the multi-cavity drainage tube 1; a plurality of second drainage openings 1-2-1 of the second drainage cavity 1-2 are arranged at the position close to the tail part of the first drainage cavity 1-1.
The multi-cavity drainage tube 1 is provided with a plurality of drainage cavities, when the multi-cavity drainage tube 1 is used, the head end part is arranged in the thoracic cavity and used for draining gas or liquid in the thoracic cavity, and the tail end part is fixed outside the thoracic cavity and used for being connected with a drainage container. Most drainage of the thoracic cavity involves both fluid, mainly blood or pleural effusion, and gas. In order to ensure that the multi-cavity drainage tube 1 can simultaneously drain gas at the upper part of the thoracic cavity and liquid at the lower part smoothly, a plurality of first drainage ports 1-1-1 of one part of drainage tube cavities (first drainage cavities 1-1) of the multi-cavity drainage tube 1 are arranged at the head part of the multi-cavity drainage tube 1, and a plurality of second drainage ports 1-2-1 of the other part of drainage tube cavities (second drainage cavities 1-2) are arranged at the tail part position adjacent to the first drainage cavities 1-1. When in use, the first drainage cavity 1-1 and the second drainage cavity 1-2 are arranged in the thoracic cavity. The tail part of the first drainage cavity 1-1 is positioned at the position close to the chest wall in the chest cavity, and a plurality of second drainage ports 1-2-1 of the second drainage cavity 1-2 are arranged at the position. In clinic, when pneumothorax or hydrothorax occurs, a thoracic drainage tube is inserted into the second intercostal space of the upper part of the thoracic cavity or the 7 th intercostal space of the lower part of the thoracic cavity. Therefore, if the position of the multi-cavity drainage tube 1 to be placed in the thoracic cavity is the second intercostal space, the first drainage cavity 1-1 of the multi-cavity drainage tube 1 is placed downwards into the thoracic cavity, and the corresponding first drainage openings 1-1-1 are positioned at the bottom of the thoracic cavity, so that the drainage of liquid at the bottom of the thoracic cavity, such as blood, pleural effusion and the like, is facilitated. And a plurality of second drainage ports 1-2-1 of the second drainage cavity 1-2 are positioned at the tail part of the first drainage cavity 1-1 positioned in the thoracic cavity, namely the upper part of the thoracic cavity, so that the air at the upper part of the thoracic cavity can be conveniently drained. The first drainage lumen 1-1 and the second drainage lumen 1-2 can be provided with a plurality of numbers, in this illustration, the first drainage lumen 1-1 and the second drainage lumen 1-2 are both provided with one. In other figures of this specification, the first drainage lumen 1-1 and the second drainage lumen 1-2 are provided as one, and will not be described in detail below.
In fact, the positions of the second drainage openings 1-2-1 of the second drainage cavity 1-2 at the tail parts of the first drainage cavity 1-1 in the chest cavity are constant, and the sizes of the spaces in the chests of patients with different heights are different, even the difference is very large, so that the multi-cavity drainage tubes 1 with different lengths are required to be adapted for use. When the drainage device is used specifically, the first drainage cavity 1-1 is long, the use requirement of the highest patient can be met, and when the patient with a short height uses the drainage device, the head end of the first drainage cavity 1-1 can be cut according to the length of the chest cavity of the patient, so that the length of the first drainage cavity 1-1 is suitable to be adjusted to meet the clinical requirement. After the length is cut, side incisions can be made on the side wall of the head end of the residual tube cavity of the first drainage cavity 1-1, so that smoothness in drainage is ensured.
The multi-cavity drainage tube 1 comprises a first connecting tube 1-1-2 which is communicated with a first drainage cavity 1-1 and is positioned outside the thoracic cavity and a second connecting tube 1-2-2 which is communicated with a second drainage cavity 1-2 and is positioned outside the thoracic cavity. In fact, the first connecting tube 1-1-2 is a continuation of the first drainage lumen 1-1 outside the thoracic cavity, and the essential structure thereof may not be different, and the different names in the description of the present invention are only for facilitating understanding of the distinction of the multi-lumen drainage tube 1 inside and outside the chest wall and for facilitating understanding of the position of the multi-lumen drainage tube 1 placed in the thoracic cavity. Corresponding to the plurality of first drainage cavities 1-1, corresponding numbers can be made on the first connecting pipes 1-1-2, and the first connecting pipes 1-1-2 can be gathered into a tube cavity. Because the positions of the first drainage ports 1-1-1 of the first drainage cavities 1-1 are very close, the two drainage cavities have no obvious difference in specific drainage. Similarly, corresponding to the second drainage cavities 1-2, corresponding numbers can be made on the second connecting tubes 1-2-2, and the second connecting tubes 1-2-2 can be collected into a tube cavity. However, the second connecting pipe 1-2-2 and the second connecting pipe 1-2-2 should be isolated from each other, because the distances between the first drainage openings 1-1-1 and the second drainage openings 1-2-1 are far away, the drainage positions are greatly different, and the simultaneous drainage of the body positions in two thoracic cavities after the two thoracic cavities are communicated is unfavorable.
Correspondingly, the tail end of the first connecting pipe 1-1-2 is provided with a first connector 1-1-3, and the tail end of the second connecting pipe 1-2-2 is provided with a second connector 1-2-3, so that the drainage container is convenient to connect. The first interface 1-1-3 and the second interface 1-2-3 may be specifically arranged pagoda interface tubes, or may be natural continuous openings of the first connecting tube 1-1-2 and the second connecting tube 1-2-2, as long as connection of other components and pipelines can be completed, and there is no essential difference.
Furthermore, the portable thoracic drainage suit also comprises a drainage connecting pipe 2 connected to the tail ends of the first connector 1-1-3 and the second connector 1-2-3, and a one-way drainage valve membrane 2-1 is arranged in the drainage connecting pipe 2. Specifically, the one-way drainage valve membrane 2-1 can be a duckbill valve, and can also be a thin-film tube cavity with a free end at one side with an opening towards the outside of the thoracic cavity, and the opening of the thin-film tube cavity is fixedly expanded and fixed at one side with the opening towards the inside of the thoracic cavity. Like this, when the drainage outwards flows out from the thorax, the drainage can be discharged through the thin film tube that struts, and when reverse, extrathoracic pressure is great, can the flat thin film tube of collapse, leads to the thin film tube closed to block drainage reflux. Of course, the one-way drainage valve membrane 2-1 can be arranged in the drainage connecting pipe 2, can also be arranged integrally with the first connector 1-1-3 and the second connector 1-2-3, and even arranged in the first drainage cavity 1-1 and the second drainage cavity 1-2, so that the purpose is to ensure that drainage can only be discharged out of the thoracic cavity from the thoracic cavity, but can not flow back into the thoracic cavity from the outside of the thoracic cavity. Thereby avoiding the gas under the external atmospheric pressure from flowing back into the lower pressure chest through the multi-cavity drainage tube 1 and ensuring the drainage safety.
Of course, the drainage connecting pipe 2 and the one-way drainage valve membrane 2-1 arranged therein may also be integrally arranged with the first interface 1-1-3 or the second interface 1-2-3, and at this time, the first interface 1-1-3 or the second interface 1-2-3 synchronously serves as the drainage connecting pipe 2, which also belongs to the protection scope of the present invention. Even, the one-way drainage valve membrane 2-1 can be arranged in the first drainage cavity 1-1 or the second drainage cavity 1-2, and the purpose of preventing the drainage liquid from flowing back can be achieved, so that the first drainage cavity 1-1 or the second drainage cavity 1-2 near the one-way drainage valve membrane 2-1 can simultaneously serve as the drainage connecting pipe 2, and the invention also belongs to the protection scope of the invention. In the invention, the drainage connecting pipe 2 and the one-way drainage valve membrane 2-1 arranged in the drainage connecting pipe are preferably arranged independently, the advantage is that the indication connecting pipe 5 of the pressure change indicator 5-1 for displaying the pressure change in the thoracic cavity can be conveniently and conveniently arranged and connected between the first interface 1-1-3 or the second interface 1-2-3 and the drainage connecting pipe 2, and the negative pressure change in the thoracic cavity can be observed through the pressure change indicator 5-1, so that whether the first drainage cavity 1-1 and the second drainage cavity 1-2 are unobstructed or blocked or not is judged, the treatment is carried out in time, and the serious complications caused by the obstruction are avoided.
When the drainage tube is used specifically, the drainage tube positioned at the upper part of the thoracic cavity can not be connected with the drainage container, and the gas is directly discharged into the atmosphere. However, the drainage cavity connected with the lower part of the thoracic cavity must be connected with a drainage container, so that the condition of hemorrhage or seepage in the thoracic cavity can be observed conveniently, and when the drainage device is used specifically, aiming at different positions where the multi-cavity drainage tube 1 is placed, the drainage container 3 for draining liquid can be connected with the tail end of the drainage connecting tube 2 of the first connector 1-1-3 or the second connector 1-2-3. The specific connection position is the position of the first drainage opening 1-1-1 or the second drainage opening 1-2-1 in the thoracic cavity, and when the first drainage opening 1-1-1 is higher than the second drainage opening 1-2-1, the drainage container 3 is connected with the second connector 1-2-3; on the contrary, when the first drainage port 1-1-1 is lower than the second drainage port 1-2-1, the drainage container 3 is connected with a connector 1-1-3.
As shown in fig. 1, 4 and 8, the portable chest drainage kit further comprises an exhaust drainage bag 4 for draining gas; the exhaust drainage bag 4 is provided with an exhaust port 4-1 which can be communicated with the outside of the exhaust drainage bag 4; the exhaust port 4-1 is provided with a water-blocking and air-permeable membrane 6; the exhaust drainage bag 4 is provided with a first sealing body at the exhaust port 4-1 part, and the exhaust port 4-1 can be closed. When the gas is discharged from the chest cavity, the gas in the lung often enters the chest cavity along with continuous gas, along with respiratory movement, the gas flow discharged from the chest cavity through the multi-cavity drainage tube 1 is large, the volume of the gas discharged from the chest cavity is large, and the volume of the exhaust drainage bag 4 can not meet the clinical use requirement. When the gas in the exhaust drainage bag 4 is not removed in time after being full, the gas in the thoracic cavity can not be discharged continuously, so that the pressure in the thoracic cavity is increased, and then the pressure pneumothorax is caused, and serious consequences are caused. After the exhaust drainage bag 4 is provided with the exhaust port 4-1, gas exhausted into the exhaust drainage bag 4 can be directly exhausted into the atmosphere through the exhaust port 4-1, so that the problem that when the quantity of drainage gas is large, the gas is accumulated in the drainage bag, the pressure of the drainage bag rises after the gas is rapidly saturated, the gas in the thoracic cavity cannot be drained during subsequent drainage, the gas is accumulated in the thoracic cavity, and even the affected lung is compressed, and risks are caused is avoided.
In fact, the exhaust drainage bag 4 can replace the drainage container 3 and is connected to the tail end of the drainage connecting pipe 2 of the first connector 1-1-3 or the second connector 1-2-3, and drainage liquid can be discharged. Moreover, when liquid in the thoracic cavity needs to be drained, liquid column pressure (P = ρ gh, P is the liquid column pressure, ρ is the liquid density, g is the gravity coefficient, and h is the liquid column height) is generated at the bottom of the liquid containing cavity, so that the pressure difference of the wall of the first drainage port 1-1-1 or the wall of the second drainage port 1-2-1 in the liquid cavity in the air cavity is larger, and the liquid is more easily drained out of the thoracic cavity and enters the drainage bag. However, the pressure difference is small, and the effect of preferential drainage of the liquid is slightly poor.
As shown in fig. 4, 9, 10, 11 and 12, the portable thoracic drainage suit further comprises an indication connecting pipe 5 which is connected and arranged at the tail ends of the first connector 1-1-3 and the second connector 1-2-3 and in front of the one-way drainage valve membrane 2-1, and the indication connecting pipe 5 is communicated with a pressure change indicator 5-1 for displaying the change of the intrathoracic pressure. In specific implementation, the indication connecting pipe 5 must be arranged in front of the one-way drainage valve membrane 2-1, that is, must be communicated with the inner cavity of the first drainage cavity 1-1 or the second drainage cavity 1-2, and the one-way drainage valve membrane 2-1 cannot be arranged between the first drainage cavity 1-1 or the second drainage cavity 1-2 and the indication connecting pipe 5. Therefore, when the intrathoracic pressure changes along with respiration, the intrathoracic pressure is transmitted into the first drainage cavity 1-1 or the second drainage cavity 1-2, so that the pressure change of the first drainage cavity 1-1 or the second drainage cavity 1-2 can be transmitted into the indication connecting pipe 5, and the pressure change indicator 5-1 displays the pressure change. When the pressure change indicator is used, the pressure change condition of the first drainage cavity 1-1 or the second drainage cavity 1-2 can be judged by observing the pressure change display of the pressure change indicator 5-1.
Under normal conditions, as the patient moves in a breathing mode, the pressure in the chest cavity fluctuates along with the breathing rhythm, and the pressure change of the pressure change indicator 5-1 also fluctuates along with the breathing rhythm. When the pressure change of the pressure change indicator 5-1 is weakened or stopped, it can be judged that the first drainage chamber 1-1 or the second drainage chamber 1-2 is not unobstructed enough or completely blocked. At the moment, if air leakage or liquid seepage occurs in the thoracic cavity, air or liquid can be accumulated in the thoracic cavity, so that the pressure in the thoracic cavity is increased, the lung is compressed and must be treated in time, otherwise, the weak people have atelectasis, and the heavy people have life risks.
As shown in figure 5, the distance between the first drainage openings 1-1-1 and the second drainage openings 1-2-1 is long, the drainage position difference is large, when gas or liquid is reserved between the first drainage openings 1-1-1 and the second drainage openings 1-2-1 in the chest cavity, the gas cavity is not communicated with the first drainage openings 1-1 and the second drainage openings 1-2-1 due to the fact that lung tissues are attached to the side wall of the first drainage cavity 1-1, and the gas or liquid cannot be effectively drained due to the fact that the gas cavity is not communicated with the first drainage openings 1-1 and the second drainage openings 1-2-1. To avoid this, as shown in FIG. 6, a second drainage groove 1-2-4 is formed in the sidewall of the first drainage cavity 1-1 corresponding to the channel position of the second drainage cavity 1-2. The second drainage grooves 1-2-4 are arranged to form grooves in the second drainage grooves 1-2-4 on the side wall of the first drainage cavity 1-1, so that lung tissues are difficult to cling to the side wall of the first drainage cavity 1-1, and gas or liquid cavities between the first drainage openings 1-1-1 and the second drainage openings 1-2-1 can be communicated with the first drainage openings 1-1-1 and the second drainage openings 1-2-1 through the grooves of the second drainage grooves 1-2-4, so that gas is drained through the drainage openings above the thoracic cavity, and liquid is drained through the drainage openings below the thoracic cavity.
Further, as shown in fig. 7, on both sides of the channel corresponding to the second drainage cavity 1-2, second drainage lateral wings 1-2-5 are arranged on the side wall of the first drainage cavity 1-1. The scheme is an optimization of fig. 6, and second drainage flanks 1-2-5 are arranged on two sides of a channel corresponding to a second drainage cavity 1-2, so that a groove structure similar to the second drainage grooves 1-2-4 is formed between the pair of second drainage flanks 1-2-5. Meanwhile, the second drainage side wings 1-2-5 can further prevent lung tissues from being tightly attached to the second drainage grooves 1-2-4, prevent the lung tissues from being tightly attached to the side walls of the first drainage cavity 1-1, prevent the gas cavity from being not communicated with the first drainage openings 1-1-1 and the second drainage openings 1-2-1, and prevent gas or liquid from being drained effectively. The second drainage flanks 1-2-5 are arranged to enable the gas or liquid cavities between the plurality of first drainage ports 1-1-1 and the plurality of second drainage ports 1-2-1 to be respectively communicated with the plurality of first drainage ports 1-1-1 and the plurality of second drainage ports 1-2-1 through gaps between the pair of second drainage flanks 1-2-5, so that gas is drained through the drainage ports above the thoracic cavity, and liquid is drained through the drainage ports below the thoracic cavity.
As shown in fig. 12, the buckling indicator 5-1 includes: the blind cavity 5-2 is communicated with the indication connecting pipe 5, a pressure sensor 5-3, a pressure change indicator lamp 5-4 and a power supply 5-5 are electrically connected in the blind cavity 5-2, and a water-blocking breathable film 6 is arranged at the communicated part of the blind cavity 5-2 and the indication connecting pipe 5. When the thoracic cavity drainage device is used, the indication connecting pipe 5 is communicated with the first drainage cavity 1-1 or the second drainage cavity 1-2, and the first drainage cavity 1-1 or the second drainage cavity 1-2 are communicated with the intrathoracic space and change along with the change of the pressure of the intrathoracic space. The pressure sensor 5-3 can sense the communicated intrathoracic pressure, the pressure-change indicator lamp 5-4 is well set with light trigger pressure, the pressure-change indicator lamp 5-4 is lightened when the pressure exceeds the set pressure, and the pressure-change indicator lamp 5-4 is extinguished when the pressure is lower than the set pressure. The triggering pressure of the pressure sensor 5-3 is set to be in a low value range of the thoracic cavity pressure during normal breathing, and the pressure change indicator lamp 5-4 can twinkle in rhythm along with the breathing of a patient. When the first drainage cavity 1-1 or the second drainage cavity 1-2 is blocked, the correspondingly arranged pressure sensor 5-3 can not sense the change of the pressure in the thoracic cavity, and can continuously light up or extinguish, so that the blockage of the first drainage cavity 1-1 or the second drainage cavity 1-2 can be judged, and the blocked first drainage cavity 1-1 or the blocked second drainage cavity 1-2 can be dredged in time.
In order to avoid short circuit of the pressure sensor 5-3, the pressure-variable indicator lamp 5-4 and the power supply 5-5 caused by the fact that liquid drained from the first drainage cavity 1-1 or the second drainage cavity 1-2 flows into the blind cavity 5-2, a water-blocking breathable film 6 is arranged at the communicating part of the blind cavity 5-2 and the indication connecting pipe 5. The surface of the water-blocking breathable film 6 is provided with small micropores, and gas can pass through the water-blocking breathable film 6, so that the change of the intrathoracic pressure can be transmitted to the pressure sensor 5-3, and the pressure change indicator lamp 5-4 can twinkle along with the change of the intrathoracic pressure. Meanwhile, liquid cannot pass through the water-blocking and breathable film 6, so that the liquid cannot enter the blind cavity 5-2, and the short circuit of the pressure sensor 5-3, the pressure change indicator lamp 5-4 and the power supply 5-5 is avoided. The water-blocking and air-permeable film 6 is a common material, preferably polytetrafluoroethylene is an artificially synthesized polymer material using fluorine to replace all hydrogen atoms in polyethylene, and details are not repeated here.
As shown in fig. 11, another embodiment of the pressure-change indicator 5 includes: a sleeve 5-6 communicated with the indication connecting pipe 5, and a spring 5-7 and a sealing piston 5-8 are arranged in the sleeve 5-6. When the scheme is adopted, the friction force between the sealing piston 5-8 and the sleeve 5-6 needs to be controlled in a small range as much as possible, and super-lubricating materials can be coated on the surface of the sealing piston 5-8 and the side wall of the inner cavity of the sleeve 5-6. The springs 5-7 need to be made of a thin, elastic material. The sleeve 5-6 is in communication with the atmosphere on the other side relative to the spring 5-7 and is in communication with the first drainage lumen 1-1 or the second drainage lumen 1-2 on one side of the spring 5-7. When inhaling, the negative pressure in the chest cavity is increased, the difference between the external atmospheric pressure and the pressure in the chest cavity is increased, so that the sealing piston 5-8 slides towards one side of the spring 5-7 until the spring 5-7 is compressed to a certain limit, and the stress of the sealing piston 5-8 is balanced. When exhaling, the negative pressure in the chest cavity becomes smaller, the difference between the external atmospheric pressure and the pressure in the chest cavity becomes smaller, so that the sealing piston 5-8 slides to the side communicated with the atmosphere until the spring 5-7 relaxes to a certain limit to balance the stress of the sealing piston 5-8. Therefore, the sealing piston 5-8 slides back and forth in the sleeve 5-6, so that the change of the pressure in the thoracic cavity along with the respiratory rhythm can be judged, and the smoothness or blockage of the first drainage cavity 1-1 or the second drainage cavity 1-2 can be further judged.
As shown in fig. 9 and 10, the buckling indicator 5 includes: the sleeve 5-9 is communicated with the indication connecting pipe 5, the sleeve 5-9 is internally sleeved with a negative pressure indication air bag 5-10 in a sealing manner, the cavity of the negative pressure indication air bag 5-10 is communicated with outside air, and the cavity of the negative pressure indication air bag 5-10 is isolated from the indication connecting pipe 5. When the scheme is adopted, the negative pressure indicating air bag 5-10 needs to be made of a thin material with good elasticity, the expansion and the reduction of the bag cavity of the negative pressure indicating air bag 5-10 are alternately carried out along with the fluctuation of the negative pressure in the thoracic cavity in the breathing movement, so that the breathing rhythm can be observed, and the smoothness or the blockage of the first drainage cavity 1-1 or the second drainage cavity 1-2 can be judged.
Specifically, when inhaling, the negative pressure in the chest cavity is increased, the difference between the external atmospheric pressure and the pressure in the chest cavity is increased, and the external gas enters the 5-10 cavities of the negative pressure indicating air bags, so that the 5-10 cavities of the negative pressure indicating air bags are expanded. When the patient exhales, the negative pressure in the thoracic cavity is reduced, the difference between the external atmospheric pressure and the intrathoracic pressure is reduced, so that the air part of the 5-10 cavities of the negative pressure indicating air bags is discharged, and the 5-10 cavities of the negative pressure indicating air bags are shrunk. Furthermore, a water-blocking breathable film 6 is arranged at the position of the indication connecting pipe 5 communicated with the sleeve 5-9, so that when drainage is carried out, the drained liquid can be prevented from entering the sleeve 5-9, and the part of the bag wall of the negative pressure indication air bag 5-10 is pasted on the inner wall of the sleeve 5-9, so that the free expansion and contraction change of the negative pressure indication air bag 5-10 is influenced.
To further ensure preferential drainage of the liquid, the drainage receptacle 3 comprises a negative pressure builder 3-1 and a drainage bag 3-2, as shown in fig. 13, 14, 15. The communicating part of the negative pressure builder 3-1 and the drainage bag 3-2 is provided with a one-way valve film 3-3 communicated from the negative pressure builder 3-1 to the drainage bag 3-2. The negative pressure builder 3-1 is a container with elastic retractility, and comprises a cylindrical container, an elastic rubber or silica gel container and the like, wherein a spring is arranged in the cylindrical container. However, in order to reduce the volume and weight of the drainage and drainage container 3 and further facilitate carrying, the drainage and drainage container 3 further comprises a drainage bag 3-2 communicated with the negative pressure builder 3-1, and after the drainage space of the negative pressure builder 3-1 is full, drainage materials can enter the drainage bag 3-2. The drainage bag 3-2 has small volume, light weight and large volume and can store more drainage materials. When the patient feels that the drainage in the drainage bag 3-2 is more, the weight of the drainage container 3 can be reduced by discharging the drainage in the drainage bag 3-2.
As shown in fig. 13 and 14, the negative pressure builder 3-1 comprises a third port 3-1-1 for communicating with a drainage line, an elastic container part 3-1-2 and a one-way valve membrane 3-3 communicating from the inner cavity of the elastic container part 3-1-2 to the outside of the cavity; and a water-blocking and air-permeable membrane 6 is arranged on one side of the one-way valve membrane 3-3, which is close to the elastic container part 3-1-2. The negative pressure builder 3-1 can be connected with the drainage tube through a third interface 3-1-1; the elastic re-tensioning action of the elastic container part 3-1-2 can enable the cavity of the elastic container part 3-1-2 to generate negative pressure, so as to achieve the negative pressure drainage effect.
The specific use process and the working principle are as follows:
1. when drainage is started, the elastic container part 3-1-2 is pressed, so that the elastic container part 3-1-2 is shriveled, and the third connector 3-1-1 is connected to the drainage pipeline. The elastic container part 3-1-2 is released, and the elastic container part 3-1-2 has a tendency to open under the elastic re-tensioning action of the elastic container part 3-1-2. Under the action of the one-way valve film 3-3 communicated from the elastic container part 3-1-2 to the drainage bag 3-2, the content in the drainage bag 3-2 can not enter the elastic container part 3-1-2. Meanwhile, the one-way valve membrane 3-3 communicated from the inner cavity of the elastic container part 3-1-2 to the outside of the cavity prevents outside air from entering the elastic container part 3-1-2, so that the cavity of the elastic container part 3-1-2 can be kept in a negative pressure state. But the drainage pipeline can be communicated with the thoracic cavity space of the patient through the one-way drainage valve membrane 2-1, so that the gas and liquid in the thoracic cavity can enter the elastic container part 3-1-2 through the one-way drainage valve membrane 2-1, thereby achieving the drainage effect. The negative pressure in the cavity of the elastic container part 3-1-2 is gradually reduced along with the air and liquid in the thoracic cavity entering the elastic container part 3-1-2;
2. when the intrathoracic drainage matter enters the elastic container part 3-1-2 to a large extent, so that the containing cavity of the elastic container part 3-1-2 is filled with the drainage matter, the negative pressure of the elastic container part 3-1-2 disappears, and at the moment, under the action of the intrathoracic expiratory pressure, the drainage matter in the containing cavity of the elastic container part 3-1-2 can enter the drainage bag 3-2 through the one-way valve membrane 3-3 communicated with the drainage bag 3-2 by the elastic container part 3-1-2. At the moment, the drainage in the elastic container part 3-1-2 tends to be discharged through a one-way valve film 3-3 communicated from the inner cavity of the elastic container part 3-1-2 to the outside of the cavity, but a water-blocking breathable film 6 is arranged on one side of the one-way valve film 3-3 close to the elastic container part 3-1-2, and liquid can not be discharged out of the elastic container part 3-1-2 through the passage under the action of the water-blocking breathable film 6; but gas can be discharged out of the elastic container portion 3-1-2 through this passage. Under the action of the one-way valve membrane 3-3 communicated from the inner cavity of the elastic container part 3-1-2 to the outside of the cavity, the drainage liquid can enter the drainage bag 3-2, but the drainage gas can be directly discharged outside. So that the drainage liquid drainage container 3 can store more drainage liquid. Generally, most of the gas in the chest drainage is less, the liquid is less, the volume is below 300ml, and the smaller drainage bag 3-2 can meet most of the use requirements. And the gas with larger drainage volume can be discharged through the one-way valve membrane 3-3 communicated from the inner cavity of the elastic container part 3-1-2 to the outside of the cavity, so that the liquid drainage and drainage container 3 is ensured not to be filled with drainage gas quickly to cause pressure rise and gas-liquid drainage can not be continued.
3. Furthermore, when the drainage is finished, the drainage gas and liquid are less, and the drainage gas and liquid quantity needs to be accurately judged at the moment. At the moment, the gas and the liquid in the drainage container 3 are emptied, the one-way valve membrane 3-3 communicated from the inner cavity of the elastic container part 3-1-2 to the outside of the cavity is closed, the drainage bag 3-2 becomes a closed potential cavity, and after a period of time, the volume of the gas and the liquid drained from the interior of the thoracic cavity in the drainage bag 3-2 is observed, so that the volume of the gas and the liquid drained from the interior of the thoracic cavity in the period of time can be accurately calculated, and therefore whether the index of drainage ending is reached or not is judged, and drainage treatment is decided to be ended or continued.
Similarly, it is added that the exhaust drainage bag 4 can judge the time-related amount of drainage gas by the same method, so as to judge the end or continue the drainage treatment.
The difference between fig. 13 and fig. 14 is that in the embodiment of fig. 13, only one third port 3-1-1 is provided in the elastic container portion 3-1-2 for connecting with a drainage line, which can be connected with a liquid drainage line and also can be connected with a gas drainage line, so that negative pressure drainage can be realized. But as the drainage matter expands to fill the elastic container part 3-1-2, the negative pressure drainage effect is weakened. Therefore, the embodiment of fig. 13 has better effect for gas-liquid drainage with smaller drainage volume. In the embodiment shown in fig. 14, the elastic container part 3-1-2 is provided with two third ports 3-1-1 for connecting with the drainage pipeline, one is connected with the liquid drainage pipeline, and the other is connected with the gas drainage pipeline, so that negative pressure drainage effect can be realized, but after gas and liquid synchronously enter the elastic container part 3-1-2, drainage objects can rapidly expand the elastic container part 3-1-2, and the negative pressure drainage effect is weakened. Therefore, in the beginning stage of drainage, the elastic container part 3-1-2 is compressed and released for multiple times due to the negative pressure drainage effect of the elastic container part 3-1-2 as much as possible, so that gas and liquid in the thoracic cavity are discharged as much as possible, and the elastic container part 3-1-2 is compressed and released for the last time until the drainage quantity of the gas and the liquid in the thoracic cavity is extremely small, so that the negative pressure drainage is realized by using the elastic container part 3-1-2. During use, the drainage in the elastic container part 3-1-2 can be repeatedly discharged, and negative pressure is repeatedly established on the elastic container part 3-1-2 to realize negative pressure drainage.
When in specific use, the multi-cavity drainage tube 1 can achieve better drainage effect on gas and liquid in the thoracic cavity no matter being placed on the upper part of the thoracic cavity to penetrate out or penetrating out at the lower part of the thoracic cavity. Specifically, as shown in fig. 2, when the multi-cavity drainage tube 1 penetrates out of the upper part of the thoracic cavity, the first drainage ports 1-1-1 at the head end of the first drainage cavity 1-1 are embedded in the lower part of the thoracic cavity and embedded in the thoracic cavity liquid, which is very beneficial to liquid drainage. The tail end opening of the first interface 1-1-3 is sequentially connected with the indication connecting pipe 5, the one-way drainage valve film 2-1 and the liquid drainage container 3. The one-way drainage valve membrane 2-1 can prevent liquid from flowing back during drainage, avoid thoracic cavity infection caused by the backflow, and ensure the liquid drainage effect. The drainage liquid and drainage container 3 is connected to the tail end of the first connector 1-1-3 and can store drained liquid. The drainage and drainage container 3 is preferably a drainage bag, and has small volume, light weight and large volume.
Meanwhile, the second drainage openings 1-2-1 of the second drainage cavity 1-2 are embedded at the upper part of the thoracic cavity and positioned in the gas cavity channel of the thoracic cavity, which corresponds to the first drainage cavity 1-1, and is beneficial to gas drainage in the thoracic cavity. The indication connecting pipe 5 and the one-way drainage valve film 2-1 are sequentially connected and arranged at the opening at the tail end of the second connector 1-2-3, so that gas backflow can be avoided during gas drainage, and serious complications caused by the fact that a large amount of external gas flows back into the thoracic cavity can be avoided. During gas drainage, the gas discharged by drainage can be directly discharged into the atmosphere, and the exhaust drainage bag 4 can not be connected, and of course, the exhaust drainage bag 4 can also be connected. It should be noted that the gas flow rate is relatively large during gas drainage, and in order to ensure safety, as shown in fig. 8, a gas outlet 4-1 communicated with the outside gas needs to be arranged on the gas drainage bag 4. Furthermore, the matched exhaust sealing cover 4-2 is arranged corresponding to the exhaust port 4-1, when the volume of gas and liquid which is drained from the thoracic cavity in a unit time period needs to be observed, the exhaust sealing cover 4-2 is used for blocking the exhaust port 4-1, whether the gas and liquid which are drained from the thoracic cavity reach the index of drainage ending or not can be judged, and the drainage treatment is determined to be ended or continued. When the drainage can be finished, the drainage catheter is pulled out, and the skin perforation of the catheter is closed.
As shown in fig. 3, when the multi-cavity drainage tube 1 penetrates out of the lower part of the thoracic cavity, a plurality of first drainage ports 1-1-1 at the head end of the first drainage cavity 1-1 are embedded at the upper part of the thoracic cavity, and the tail end opening of the first port 1-1-3 is sequentially connected with the indication connecting tube 5, the one-way drainage valve membrane 2-1 and the exhaust drainage bag 4; meanwhile, a plurality of second drainage ports 1-2-1 of a second drainage cavity 1-2 are buried at the lower part of the thoracic cavity, and the tail end opening of the second port 1-2-3 is sequentially connected with the indication connecting pipe 5, the one-way drainage valve membrane 2-1 and the drainage container 3. At the moment, a plurality of first drainage ports 1-1-1 at the head end of the first drainage cavity 1-1 are embedded at the upper part of the thoracic cavity and correspondingly embedded in the gas cavity of the thoracic cavity; and a plurality of second drainage ports 1-2-1 of the second drainage cavity 1-2 are embedded at the lower part of the thoracic cavity and correspondingly embedded in the liquid cavity of the thoracic cavity. The specific drainage principle and method are the same as those in fig. 2, but the positions are reversed, and the detailed description is omitted here.
As shown in fig. 14 and 15, the drainage and drainage container 3 and the drainage and drainage bag 4 are integrally provided or share a drainage lumen. Or the drainage container 3 comprises a negative pressure builder 3-1 and a drainage bag 3-2, and the exhaust drainage bag 4 and the drainage bag 3-2 are integrally arranged or share a drainage cavity. In the embodiment shown in fig. 14, the drainage container 3 and the exhaust drainage bag 4 share a drainage cavity and are both a negative pressure builder 3-1 and a drainage bag 3-2, and the negative pressure builder 3-1 is provided with two third interfaces 3-1-1 which are respectively connected with the gas drainage channel and the liquid drainage channel. In the embodiment of fig. 15, the drainage container 3 comprises a negative pressure builder 3-1 and a drainage bag 3-2, and the exhaust drainage bag 4 shares the drainage bag 3-2 of the drainage container 3, so that gas-liquid drainage can be effectively implemented, and drainage safety is ensured.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
