Description

Technical Field

[0001] This utility model relates to the field of unidirectional valve-type sealing patch technology, specifically a unidirectional valve-type sealing patch for preventing compression of open chest injuries. Background Technology

[0002] Open pneumothorax refers to a pneumothorax caused by a continuously open air leakage channel, allowing air to enter and exit the pleural cavity with respiration. In most cases, the air in a pneumothorax originates from a ruptured lung caused by a fractured rib (superficial rupture, deep rupture reaching the bronchioles), or from bronchial or lung tissue contusions caused by trauma, or from a sudden increase in airway pressure leading to bronchial or lung rupture. Current chest closure dressings can convert open pneumothorax into closed pneumothorax by covering the open wound; however, trauma often results in damage to the lung within the pleural cavity, and this simple treatment of closing the open wound does not eliminate the risk of tension pneumothorax. Furthermore, traditional chest closure dressings are often obstructed by clothing, further affecting drainage and making it difficult to observe the internal valve. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a one-way valve-type sealing patch for preventing compression in open chest injuries. This solves the problem that existing chest sealing patches, when applied to open chest wounds, cause open pneumothorax to turn into closed pneumothorax. However, injuries often lead to lung damage within the chest cavity, and this treatment method, which simply closes the open chest wound, cannot eliminate the risk of tension pneumothorax. Furthermore, when using traditional chest sealing patches, clothing further affects the drainage effect and makes it difficult to observe the internal valve.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a one-way valve-type sealing patch for preventing pressure on open chest injuries. It includes an adhesive component, a hydrophobic component, and a capping component. The adhesive component includes a pressure-sensitive adhesive film with a hole in the center and drainage openings around the hole.

[0005] Preferably, the hydrophobic component includes a hydrophobic material coating layer, and the capping component includes a cap, the side of which has a drainage port.

[0006] Preferably, the front side of the adhesive component is provided with a hydrophobic material.

[0007] Preferably, the cap is fixedly connected to the surface of the adhesive component, and the drainage ports around the cap are interconnected with the application drainage ports.

[0008] Preferably, the hydrophobic material dressing layer forms a valve with the adhesive component through pressure regulation within the thoracic cavity.

[0009] Preferably, the surface of the cap is transparent.

[0010] This invention provides a one-way valve-type sealing patch for preventing compression in cases of open chest injuries. Compared with existing technologies, it has the following advantages:

[0011] 1. A one-way valve-type sealing dressing for preventing compression of open chest injuries, comprising two films forming a one-way valve. The pressure-sensitive adhesive film is tightly adhered to the chest wall surface, and the hydrophobic material layer and the pressure-sensitive adhesive film are connected through a central hole to form a one-way valve. The hole formed between the films is connected to the pressure inside the chest cavity through a drainage port. As the pressure inside the chest cavity increases, the negative pressure inside the chest cavity increases when the patient inhales, causing the upper and lower films to close and seal the hole, preventing further gas from entering the chest cavity. When the patient exhales, the negative pressure inside the chest cavity decreases, the upper and lower films separate, and the hole opens, facilitating the outflow of excess gas and / or effusion from the chest cavity, thus maintaining the pressure inside the chest cavity.

[0012] 2. A one-way valve-type sealing dressing for preventing pressure on open chest injuries, featuring a 1cm high cap that allows direct viewing of the valve drainage from the front, preventing clothing from obscuring the valve and rendering it ineffective. Three drainage openings on the side connect to the drainage port for easy drainage of liquids and gases. Rotating the cap to cover the drainage port creates a sealed drainage system. The perforation in the center of the adhesive film, along with the pressure-sensitive adhesive film, forms a one-way valve under respiratory action, preventing gas or liquid from entering the drainage port from the chest cavity while allowing it to drain out. This eliminates the risk of tension pneumothorax associated with traditional chest wall sealing dressings. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a one-way valve-type sealing dressing for preventing compression in open chest injuries. It includes an adhesive component, a hydrophobic component, and a capping component. The adhesive component includes a pressure-sensitive adhesive film 1 with a hole 2 in the center and drainage openings 3 around the hole 2. The pressure-sensitive adhesive film 1 is adhesive, enabling it to firmly adhere the sealing dressing to the skin around the wound. The hole 2 and drainage openings 3 facilitate the drainage of gas and fluid in practical applications involving open chest wounds. The front side of the adhesive component is made of a hydrophobic material 4.

[0021] Please see Figure 1-5 The hydrophobic component includes a hydrophobic material dressing layer 5, and the sealing component includes a sealing cap 6. A drainage port 7 is provided on the side of the sealing cap 6. During the patient's breathing, this layer effectively seals the wound by regulating the pressure within the chest cavity and forming a valve with the dressing component, preventing gas and fluid from entering the chest cavity. During exhalation, the pressure within the chest cavity increases, expelling gas and fluid through the holes 2 and the dressing drainage port 3. A hydrophobic material 4 is provided on the front of the dressing component. The sealing cap 6 is fixedly connected to the surface of the dressing component. The drainage ports 7 around the sealing cap 6 are interconnected with the dressing drainage port 3. Layer 5 forms a valve through pressure regulation within the thoracic cavity and the adhesive component. The surface of the cover 6 is transparent, allowing direct observation of the valve drainage from the front. It is 1cm high to prevent clothing from obscuring the valve and causing it to lose its function. There are three drainage ports 7 on the side, which are connected to the dressing drainage port 3 to facilitate the drainage of liquids and gases. When the drainage ports 7 are rotated to cover the dressing drainage port 3, it forms a sealed drainage system. The hole 2 in the middle of the pressure-sensitive adhesive film 1 and the hydrophobic dressing layer 5 form a one-way valve under the action of breathing, which can prevent gas or liquid from entering the hole 2 from the thoracic cavity, but allows them to be discharged from the dressing drainage port 3.

[0022] When using this procedure, first clean the wound. Before applying the occlusive dressing, clean the wound with clean saline or other appropriate cleaning agent. Use the sterile brush from the thoracentesis kit to ensure the wound is sterile. Peel off the isolation layer on the surface of the occlusive dressing and apply the pressure-sensitive adhesive film 1 to the wound, ensuring that the pressure-sensitive adhesive film 1 completely covers the wound and that the hole 2 is located in the center of the open wound on the chest wall. The pressure-sensitive adhesive film 1 around the wound should adhere tightly to the skin. By using two films to form a one-way valve, the pressure-sensitive adhesive film 1 adheres tightly to the surface of the chest wall. The water-based dressing layer 5 and the pressure-sensitive adhesive film 1 are connected by a central hole 2, forming a one-way valve. The hole 2 between the films is connected to the pressure inside the thoracic cavity through the dressing drainage port 3. As the pressure inside the thoracic cavity increases, the negative pressure inside the thoracic cavity increases when the patient inhales, causing the upper and lower films to close and seal the hole 2, preventing further gas from entering the thoracic cavity. When the patient exhales, the negative pressure inside the thoracic cavity decreases, and the upper and lower films separate, allowing the hole 2 to open, facilitating the outflow of excess gas and / or effusion from the thoracic cavity, thus maintaining the pressure inside the thoracic cavity.

[0023] In this embodiment, a one-way valve-type sealing patch for preventing compression of open chest injuries is described. The structural features and working principle of the above components are based on existing technologies and will not be detailed here.
