Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an open pneumothorax closed drainage device for emergency treatment. Background Art
[0002] Open pneumothorax is usually caused by external penetrating injury that creates a hole in the chest wall with a diameter larger than 2 / 3 of the trachea diameter. External air quickly enters the human chest cavity due to reduced resistance, causing the negative pressure in the chest cavity to quickly reach equilibrium with the atmospheric pressure, resulting in the formation of pneumothorax. The first aid principle for open pneumothorax is to convert the open pneumothorax into a closed pneumothorax and perform closed chest drainage at the same time.
[0003] At present, the existing solution for this type of pneumothorax is to block the penetrating wound as soon as possible and drain the air that has entered the human body. However, when encountering such pneumothorax patients outside the hospital, there is no special first aid tool to seal and drain the chest wall wound, and only thick gauze pads can be used for simple blocking, which delays the first aid and poses a hidden danger to the treatment of patients.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0034] See also Figure 1 to Figure 2 The utility model provides an emergency open pneumothorax closed drainage device, comprising a drainage tube 10, an expansion sealing component 20 and a fixing piece 30. The two ends of the drainage tube 10 are respectively an outer end and an inner end. The inner end of the drainage tube 10 is used to be inserted into a chest wound, and the outer end of the drainage tube 10 is threadedly provided with a drainage piece 40; the expansion sealing component 20 is arranged on the outer side of the inner end of the drainage tube 10, and is used to block the wound on the patient's chest wall. The fixing piece 30 is fixedly arranged on the outer end of the drainage tube 10, and is used to be adhered to the patient's chest skin, so that the drainage tube 10 is fixed at the patient's chest wound.
[0035] During use, when the patient's chest wall is injured to form an open pneumothorax, the inner end of the drainage tube 10 is inserted into the wound on the patient's chest wall. At this time, the expansion and sealing component 20 is located on the inside of the wound. Thereafter, the expansion and sealing component 20 is inflated so that the expansion and sealing component 20 begins to expand. After the expansion and sealing component 20 expands, its outer wall is pressed against the inner wall of the wound. At this time, there is no gap between the outer wall of the expansion and sealing component 20 and the wound, thereby sealing the chest wound and forming a closed environment inside the chest; then, the fixing member 30 is pasted on the chest skin to fix the drainage tube 10; and the drainage member 40 is a one-way flow structure, so that the high-pressure gas in the chest cavity can be discharged to the outside through the drainage tube 10, but the outside air cannot enter the chest cavity, and at the same time, the liquid in the chest cavity can also be drained, so that the drainage fluid is discharged to the outside. By using this device for emergency treatment of chest wall wounds, open pneumothorax is changed to closed pneumothorax, and closed chest drainage is performed at the same time, thereby buying time for the patient to go to the hospital for treatment, so that the next step of treatment can be carried out after arriving at the hospital.
[0036] The expansion and sealing assembly 20 includes an annular airbag 21 and an inflatable member. The annular airbag 21 is fixedly sleeved on the outer side of the inner end of the drainage tube 10. The axial length between the inner end surface of the drainage tube and the fixing member is 65 mm. The inner end of the drainage tube 10 is made of a hard material, so that the annular airbag 21 can only expand outward after being inflated. The annular airbag 21 is inflated by the inflatable member so that the annular airbag 21 can expand. Among them, the inflatable member includes an inflatable balloon 22 and an inflatable tube 23. The inflatable tube 23 is fixedly arranged on the outer wall of the drainage tube 10, and one end of the drainage tube 10 is fixedly connected to the annular airbag 21, and the other end is plugged with an inflatable valve 24. The end of the annular airbag 21 can be inserted into the inflatable valve 24 for inflation.
[0037] When the inner end of the drainage tube 10 is inserted into the wound of the patient's chest wall, the end of the inflatable balloon 22 is inserted into the inflation valve 24, and then the inflatable balloon 22 is continuously squeezed to inflate the annular balloon 21, so that the annular balloon 21 begins to expand, and then the outer wall of the annular balloon 21 is squeezed and fits on the inner wall of the wound. At this time, the inside of the chest cavity is no longer connected to the outside world, and the wound is finally blocked to form a closed pneumothorax. Moreover, the wound is blocked by the rapid expansion of the annular balloon 21, which reduces the time of connection between the inside of the chest cavity and the outside world. At the same time, the annular balloon 21 can adjust the expansion degree according to the size of the wound, causing compression on the inner wall of the wound, playing a role in compression and hemostasis.
[0038] Preferably, an anesthetic is coated on the outer wall of the annular airbag 21. The anesthetic acts on the inner wall tissue of the wound after the outer wall of the annular airbag 21 contacts the inner wall of the wound, thereby reducing the pain of the patient.
[0039] like Figure 1 and Figure 2As shown, in this embodiment, the fixing member 30 includes a fixing patch 31, which is fixedly sleeved on the outer end of the drainage tube 10, and a viscose is provided on the side of the fixing patch 31 facing the skin, and a film 32 is provided on the outer side of the viscose. The fixing patch 31 is circular or rectangular in shape, which increases the contact area between the fixing patch 31 and the skin and enhances the fixing stability of the drainage tube 10. After the wound is sealed by the expansion of the annular airbag 21, the fixing patch 31 is pasted on the skin around the wound, so that the drainage tube 10 is fixed and the drainage tube 10 is prevented from sliding.
[0040] like Figure 1-Figure 5 As shown, in this embodiment, the drainage member 40 includes a drainage sleeve 41 and a sealing plate 42. The outer end of the drainage tube 10 is made of soft material. One end of the drainage sleeve 41 is threadedly sleeved on the outer side of the outer end of the drainage tube 10, and the outer fixed sleeve of the other end is provided with a ring plate 43. The side of the ring plate 43 is provided with multiple elastic holes 4, and springs 44 are fixedly arranged in the multiple elastic holes 4. The other ends of the multiple springs 44 are fixedly connected to the circumferential side edge of the sealing plate 42. In the initial state, the spring 44 is in a stretched state, so that the sealing plate 42 is tightly attached to the end face of the drainage sleeve 41.
[0041] After the annular airbag 21 is inflated to seal the wound, if there is too much air remaining in the chest cavity and the internal pressure is greater than the external pressure, the airflow will flow into the drainage sleeve 41. At this time, since the internal pressure of the drainage sleeve 41 is greater than the external pressure, the airflow of the drainage sleeve 41 can push the sealing plate 42 to move. At this time, a gap appears between the sealing plate 42 and the end surface of the drainage sleeve 41, so that the airflow of the drainage sleeve 41 flows to the outside; when the pressure in the chest cavity decreases, the recovery elastic force of the spring 44 is used to pull the sealing plate 42 to fit the end surface of the drainage sleeve 41 again, and the chest cavity becomes a closed environment again. If there is a lot of liquid in the chest cavity, the liquid will also be drained from the drainage sleeve 41 to the outside.
[0042] Preferably, the drainage member 40 further includes a plurality of guide rods 46, and a guide hole 47 is provided on the end surface of the ring plate 43 away from the drainage tube 10, one end of each of the plurality of guide rods 46 is fixedly connected to the circumferential side edge of the sealing plate 42, and the other ends of the plurality of guide rods 46 are respectively inserted into the corresponding guide holes 47 for sliding connection. The setting of the guide rods 46 has a limiting guiding function, so as to prevent the sealing plate 42 from shifting its position when moving, resulting in the failure of returning to block the drainage sleeve 41.
[0043] Furthermore, a sealing gasket 48 is fixedly provided on the side of the sealing plate 42 close to the drainage sleeve 41, and the sealing gasket 48 can strengthen the sealing between the sealing plate 42 and the end face of the drainage sleeve 41. The side of the sealing plate 42 close to the drainage sleeve 41 is an outer convex surface, so that the convex part of the sealing plate 42 extends into the drainage sleeve 41, thereby strengthening the sealing between the sealing plate 42 and the end face of the drainage sleeve 41.
[0044] The working principle of the utility model is as follows: when the patient's chest wall is injured to form an open pneumothorax, the inner end of the drainage tube 10 is inserted into the wound on the patient's chest wall. At this time, the annular airbag 21 is located on the inner side of the wound. Then, the end of the inflatable balloon 22 is inserted into the inflation valve 24. Then, the inflatable balloon 22 is continuously squeezed to inflate the annular airbag 21, so that the annular airbag 21 begins to expand, and then the outer wall of the annular airbag 21 is squeezed and fits on the inner wall of the wound. At this time, the inside of the chest cavity is no longer connected to the outside world, and the wound is finally blocked to form a closed pneumothorax; and the anesthetic on the annular airbag 21 acts on the inner wall tissue of the wound, thereby reducing the patient's pain; and the annular airbag 21 can adjust the degree of expansion according to the size of the wound, causing compression on the inner wall of the wound, playing a role in compression and hemostasis.
[0045] When the annular airbag 21 expands to seal the wound, if there is too much air remaining in the chest cavity and the internal pressure is greater than the external pressure, the airflow will flow into the drainage sleeve 41 and push the sealing plate 42 to move, so that the airflow of the drainage sleeve 41 flows to the outside through the gap between the sealing plate 42 and the end surface of the drainage sleeve 41; when the pressure in the chest cavity decreases, the sealing plate 42 is pulled to fit the end surface of the drainage sleeve 41 again by the restoring elastic force of the spring 44, and the chest cavity becomes a closed environment again. If there is a lot of liquid in the chest cavity, the liquid will also be drained from the drainage sleeve 41 to the outside.
[0046] Beneficial effects of the utility model: the emergency closed drainage device for open pneumothorax inserts the inner end of the drainage tube 10 into the wound on the patient's chest wall, and the outer wall of the inflated annular airbag 21 is pressed against the inner wall of the wound, thereby sealing the chest wound; the one-way flow setting of the drainage piece 40 allows the excess air and the generated liquid in the chest cavity to be discharged to the outside, thereby ensuring a stable pressure in the chest cavity; and the fixed patch 31 is attached to the skin to fix the drainage tube 10 to prevent the drainage tube 10 from sliding. By using this device for emergency treatment of chest wall wounds, open pneumothorax is changed to closed pneumothorax, and closed chest drainage is performed at the same time. The operation is simple and quick, thereby buying time for the patient to go to the hospital for treatment, so that the next step of treatment can be carried out after arriving at the hospital.
