Technical Field
[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to an infection-proof sealing structure for a negative pressure suction and flushing tube. Background Art
[0002] Negative pressure therapy for trauma is a common surgical treatment method. It is used to treat patients with large local wounds, heavy contamination, and more necrotic tissue. After thorough debridement, the local tissue cannot be sutured, and the wound has a lot of exudate. By connecting the patient's wound to negative pressure suction for continuous local flushing, and cooperating with negative pressure suction to suck out the flushing fluid, negative pressure therapy for trauma can continuously flush the wound contaminants, promote the growth of local tissue granulation, promote tissue healing, and help reduce and avoid the possibility of worsening inflammation and infection.
[0003] At present, when negative pressure therapy for trauma is used clinically, due to the long flushing time, the patient may need to move the body during this period for reasons such as eating or going to the toilet. However, the drainage tube on the wound is connected to the flushing liquid and the flushing tube, and one end of the flushing tube is connected to the suction device. Therefore, when the patient needs to move the body for reasons such as going to the toilet, the drainage tube needs to be disconnected from the flushing liquid, and the flushing tube needs to be disconnected from the suction device. Therefore, the port where the drainage tube is connected to the flushing liquid and the port where the flushing tube is connected to the suction device are open, and the port where the drainage tube is connected to the flushing liquid needs to be sterile, and the port where the flushing tube is connected to the suction device needs to be clean, and they may be contaminated while the patient goes to the toilet, indirectly leading to infection of the patient's wound.
[0004] In the prior art, a clamp is usually used to clamp the above two ports, but when the patient returns to the bed, he often forgets to open the clamp, and the use of the clamp cannot prevent the above two ports from being contaminated by bacteria. Therefore, an infection-proof sealing structure for a negative pressure suction flushing tube is proposed. Utility Model Content
