Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a kidney transplant wound protection device. Background Technology
[0002] After a kidney transplant, patients are extremely weak and need to be isolated to prevent airborne pathogens from infecting the wound and causing serious complications.
[0003] Existing wound protection devices after kidney transplantation aim to protect the patient's wound, prevent cross-infection by external pathogens, and avoid contact with dust and impurities in the air. These devices typically involve placing a protective cover over the outside of the wound to prevent contact with external pathogens and reduce the risk of inflammation due to cross-infection. However, existing devices have the following problems:
[0004] 1. In the existing device, when medical staff change the dressings on the wound, there may be air carrying external pathogens flowing from the outside of the isolation room into the isolation room, and there may also be air carrying external pathogens flowing around the patient's wound. Even if the medical staff puts the protective cover on the outside of the patient's wound in time after the dressing is changed, some external pathogens will still be sealed inside the protective cover along with the air. There is still a possibility that external pathogens will cross-infect the patient's wound and cause inflammation of the patient's wound.
[0005] 2. When caring for a patient's wound after surgery, it is necessary to avoid overheating the wound. When the temperature rises, some bacteria can easily multiply, thereby further increasing the risk of infection for the patient. Utility Model Content
[0006] To address the aforementioned issues, the present invention aims to provide a kidney transplant wound protection device that resolves the problem of germ-laden air coming into contact with the patient's wound after dressing changes.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A kidney transplant wound protection device includes a protective cylinder covering the area above and around the patient's wound, a disinfection component horizontally inserted into the protective cylinder, a fixing seat fixed around the lower part of the protective cylinder, an adhesive ring fixed around the fixing seat, and a suction port fixed to one side of the lower part of the protective cylinder, with one end communicating with the inside of the protective cylinder and the other end communicating with an external suction mechanism; a slot is formed through the upper part of the protective cylinder wall, and a limiting groove communicating with the slot is formed around the upper inner side wall of the protective cylinder at a height corresponding to the slot; the disinfection component includes an installation frame inserted into and engaging with the limiting groove, a disinfection net fixed inside the installation frame, and a sealing sleeve fixedly fitted outside the installation frame.
[0009] More preferably, a sealing ring is fixed between the fixed base and the protective cylinder.
[0010] More preferably, a limiting sub-assembly for further limiting the mounting frame is provided between the protective cylinder and the mounting frame; the limiting sub-assembly includes a limiting ring that is slidably disposed in the middle of the bottom wall of the limiting slot along the height direction and a return spring fixed between the limiting ring and the protective cylinder; a limiting ring groove adapted to the limiting ring is provided around the middle of the lower surface of the mounting frame.
[0011] More preferably, a handle is also fixed on one side of the sealing sleeve, which can pass through the slot and extend to the outside of the protective cylinder.
[0012] More preferably, the protective cylinder is provided with a detachable protective cover.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, after medical staff change the dressing, the disinfection component is inserted back into the protective cylinder. Then, the air inlet pipe of the suction mechanism (such as a suction pump, suction machine, etc.) is connected to the suction interface, so that the air in the space formed by the protective cylinder, the disinfection component and the patient's skin is drawn to the outside of the protective cylinder. The air that passes through the disinfection component from the top of the protective cylinder and enters the space is basically free of external germs after being disinfected by the disinfection component, thereby reducing the risk of external germs infecting the patient's wound, and thus reducing the risk of the patient's condition worsening or even causing serious complications due to cross-infection with external germs.
[0015] 2. When the temperature at the patient's wound rises, the suction mechanism can be connected to the suction interface. The suction mechanism can accelerate the airflow at the patient's wound, thereby reducing the temperature at the wound and minimizing the risk of bacterial growth and infection due to increased temperature.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] A kidney transplant wound protection device includes a protective cylinder 1 covering the upper perimeter of the patient's wound, a disinfection component 2 horizontally inserted into the protective cylinder 1, a fixing seat 3 fixed around the lower part of the protective cylinder 1, an adhesive ring 4 fixed around the lower part of the fixing seat 3, and a suction port 5 fixed to the lower side of the protective cylinder 1, with one end communicating with the inside of the protective cylinder 1 and the other end communicating with an external suction mechanism; a slot 11 is provided through the upper wall of the protective cylinder 1, and a limiting groove 12 communicating with the slot 11 is provided around the upper inner side wall of the protective cylinder 1 at a height corresponding to the slot 11; the disinfection component 2 includes an installation frame 21 inserted into and engaged with the limiting groove 12, a disinfection net 22 fixed inside the installation frame 21, and a sealing sleeve 23 fixedly sleeved outside the installation frame 21.
[0025] After the medical staff changes the dressing, the disinfection component 2 is inserted back into the protective cylinder 1. Then, the air inlet pipe of the suction mechanism, such as a suction pump or suction machine, is connected to the suction port 5. This allows the air in the space formed by the protective cylinder 1, the disinfection component 2, and the patient's skin to be drawn to the outside of the protective cylinder 1. The air entering this space from above the protective cylinder 1 through the disinfection component 2 is essentially free of external pathogens after being disinfected by the disinfection component 2, thereby reducing the risk of external pathogens infecting the patient's wound. This reduces the risk of the patient's condition worsening or even causing serious complications due to cross-infection with external pathogens. When the temperature at the patient's wound rises, the suction mechanism can also be connected to the suction port 5 to accelerate the airflow at the patient's wound, thereby lowering the temperature at the patient's wound and minimizing the possibility of pathogens multiplying and causing infection due to increased temperature.
[0026] As a possible implementation of this solution, preferably, a sealing ring 6 is fixed between the fixing seat 3 and the protective cylinder 1; the sealing ring 6 can seal the gap between the fixing seat 3 and the protective cylinder 1 to prevent external air carrying germs from flowing into the protective cylinder 1 from the gap between the two and causing infection of the patient's wound, thereby further reducing the risk of the patient's condition worsening or even causing serious complications due to cross-infection of external germs.
[0027] As a possible implementation of this solution, preferably, a limiting sub-assembly 25 for further limiting the mounting frame 21 is provided between the protective cylinder 1 and the mounting frame 21; the limiting sub-assembly 25 includes a limiting ring 251 slidably disposed in the middle of the bottom wall of the limiting groove 12 along the height direction and a return spring 252 fixed between the limiting ring 251 and the protective cylinder 1; a limiting ring groove 211 adapted to the limiting ring 251 is formed around the middle of the lower surface of the mounting frame 21; through the cooperation of the limiting ring 251 and the limiting ring groove 211, on the one hand, the protective cylinder 1 can be further limited; on the other hand, the mounting frame 21 can be further limited; The position of the mounting frame 21 is limited to prevent the mounting frame 21 from sliding out of the slot 11 as much as possible. On the other hand, it can further seal the gap between the mounting frame 21, the sealing sleeve 23 and the limiting slot 12, further reducing the risk of outside air flowing from the gap between the mounting frame 21, the sealing sleeve 23 and the limiting slot 12 into the space formed by the protective cylinder 1, the disinfection component 2 and the patient's skin. This further avoids cross-infection caused by external germs coming into contact with the patient's wound, which could worsen the patient's condition or even cause serious complications.
[0028] As a possible implementation of this solution, preferably, a handle 24 is also fixed on one side of the sealing sleeve 23, which can pass through the slot 11 and extend to the outside of the protective cylinder 1; the handle 24 facilitates the removal and insertion of the disinfection component 2.
[0029] As a possible implementation of this solution, preferably, the protective cylinder 1 is provided with a detachable protective cover 7; the protective cover 7 can isolate dust and impurities in the outside air without cooling the patient's wound or changing the dressing, so as to avoid the accumulation of dust and impurities at the patient's wound and affecting the healing of the patient's wound.
[0030] The working principle of this device is as follows:
[0031] When changing the dressing for the patient, first remove the protective cover 7 from the protective cylinder 1, and pull the disinfection component 2 out of the limiting slot 12 through the handle 24, so that there are no other objects inside the protective cylinder 1 to cover the patient's wound, thus making it easier for medical staff to change the dressing for the patient's wound. After the medical staff finishes changing the dressing, insert the disinfection component 2 back into the limiting slot 12. At this time, the limiting ring 251 stops when it abuts against the limiting ring 251 slot 211. Connect the air inlet pipe of the suction mechanism (such as a suction pump, suction machine, etc.) to the suction interface 5, so that the air in the space formed by the protective cylinder 1, the disinfection component 2 and the patient's skin is drawn to the outside of the protective cylinder 1, while the outside air will pass through the disinfection component 2 and enter the space.
[0032] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
