Background
When breathing, negative pressure can be generated in the chest cavity along with the expansion of the chest wall and the contraction of the diaphragm muscle, and air enters the lung through the upper respiratory tract and the bronchus; when the chest wall is retracted and the diaphragm muscle is relaxed, positive pressure is generated in the lungs to expel air from the respiratory tract. Open pneumothorax is caused by trauma that results in damage to the entire layer of chest wall tissue, and when the chest cavity is ruptured and the wound is left open, air will enter the chest cavity from the wound and change the pressure in the chest cavity, and air cannot enter the lungs, eventually resulting in pneumothorax, and the lungs atrophy, and if the wound exceeds the diameter of the trachea, the air entering the chest cavity will exceed the air entering the lungs, resulting in hypoxia of the body.
The treatment of open wounds to the chest is by closing the wound and avoiding air from entering the chest cavity. At present, sterile dressing or cotton pads are generally adopted to cover wounds, and then adhesive tapes or bandages are used for bandaging and fixing, so that open pneumothorax is changed into closed pneumothorax, and the closed pneumothorax is urgently sent to a hospital for further treatment. However, the existing emergency treatment method for the open pneumothorax is complex to operate and unsatisfactory in effect, the traditional dressing only simply seals the wound, and the accumulated qi, the accumulated blood and the accumulated liquid which are continuously increased in the thoracic cavity cannot be eliminated, so that hidden dangers exist, and the hidden dangers are an important factor for death of the wounded.

Detailed Description
Example (b): the present application provides a pneumothorax patch, with reference to fig. 1 to 3, comprising: a substrate 1 and a one-way valve 2.
The check valve 2 is integrally embedded in the substrate 1.
The one-way valve 2 is communicated from inside to outside in one way and corresponds to the position of the wound area of the thoracic cavity and is used for exhausting gas and/or liquid in the thoracic cavity.
The one-way valve 2 of the pneumothorax patch corresponds to the wound area, and the inner side of the substrate 1 corresponds to the wound peripheral area.
The substrate 1 has water absorption capacity for absorbing liquid guided out by the check valve, and the inner side of the substrate 1 is provided with a self-adhesive layer 5 in the area outside the check valve 2.
Optionally, there is the isolation layer self-adhesive layer when not using, tears the isolation layer and exposes the viscous layer and pastes fixedly when using.
Optionally, the substrate 1 and the one-way valve 2 are provided with a liquid guide hole 3, and the liquid guide hole 3 and the substrate 1 are integrated; the one-way valve 2 is provided with an exhaust hole 4, and the exhaust hole 4 is communicated with the outside.
The drainage hole 3 is used for guiding accumulated blood discharged through the one-way valve 2 into the water-absorbing substrate 1.
In practical application, the effusion or the hematocele in the thoracic cavity is led out through the one-way valve 2 and is led into the substrate 1 through the liquid guide hole 3, and the substrate 1 is made of water-absorbing material, so that the derived effusion can be absorbed. The pneumatosis in the chest cavity is directly exhausted to the external environment through the exhaust hole 4 after being led out by the one-way valve 2.
Optionally, the check valve 2 is a micro-pressure check valve that opens when the positive thoracic pressure is greater than a predetermined value and closes when the positive thoracic pressure is less than or equal to the predetermined value or in a negative thoracic pressure state.
For example, in practical applications, the predetermined value may be 3 mmHg.
The chest is the negative pressure under normal conditions, after forming open pneumothorax, because hydrops and pneumatosis have formed the positive pressure in the chest, this kind of positive pressure can not be too big, is slightly bigger than atmospheric pressure usually, discharges hydrops pneumatosis through minute-pressure check valve, for example minute-pressure check valve opens and discharges pneumatosis hydrops when chest positive pressure is greater than 3mmHg for the chest restores to normal minute-negative pressure, and minute-pressure check valve is closed when chest positive pressure is less than or equal to 3mmHg or the chest is negative pressure state.
In order to discharge pneumatosis and hydrops in the chest cavity and play a role of closing and opening pneumothorax, a micro-pressure one-way valve is required. It should be noted that the micro-pressure check valve is opened from inside to outside (i.e. from the inside of the chest to the outside environment) when the positive pressure in the chest is greater than a predetermined value, and is closed when the positive pressure in the chest is less than or equal to the predetermined value, and when the chest is negative pressure, the outside air pressure is greater than the chest pressure, and the micro-pressure check valve is also closed; the micro-pressure one-way valve is always normally closed from the outside to the inside (namely from the external environment to the inside of the chest cavity).
Optionally, the control member of the check valve 2 is made of at least one of silicone rubber, isoprene rubber and polytetrafluoroethylene.
Optionally, the outer side and edges of the substrate 1 are water-retaining structures.
The outer side and the edge of the substrate 1 are made into a water locking structure, so that hematocele and effusion absorbed by the substrate 1 can be locked in the substrate 1, and the cleanness of the outside of the pneumothorax patch is kept.
Optionally, the thickness of the substrate 1 is 0.5-1 cm.
Optionally, the substrate 1 is made of a high-expansion water-absorbing material, and the water-absorbing performance of the high-expansion water-absorbing material is more than 500%.
Optionally, the high expansion water absorbing material comprises at least one of a polyurethane material, a water absorbing resin, a polyvinyl alcohol material and an alginate material.
The pneumatosis, the effusion and the hematocele are usually contained in the chest cavity of the open pneumothorax, the hematocele and the effusion discharged through the one-way valve 2 can be effectively absorbed through the water absorbing material, and the hematocele and the effusion can be better absorbed by the high-expansion water absorbing material with high water absorbing performance.
In this application, the inner side of the substrate 1 refers to the side next to the thorax and the outer side refers to the side facing the environment.
To sum up, the pneumothorax subsides that this application provided, through the pneumothorax subsides that substrate and check valve are constituteed, aim at the wound position with the check valve, fix on the thorax through the self-adhesive layer, easy operation, the closure is good to the substrate possesses the water-absorbing capacity, can absorb the hydrops of deriving by the check valve, and the check valve can also discharge the pneumatosis simultaneously, not only can seal the wound, prevents that external gas, bacterium from getting into the thorax, can discharge hydrops, hematocele, pneumatosis moreover.
