Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a specimen collection conversion interface capable of adding a flushing catheter and an application thereof. Background Art

[0002] In clinical treatment, both the internal medicine system and the surgical system have their own significance for specialized diseases. The purpose is to guide the pus, blood, and fluid accumulated between human tissues or in the body cavity to the outside of the body, so as to help observe the properties of the drainage fluid, judge the recovery of organ function, prevent surgical site infection, and promote wound healing.

[0003] During treatment, if the patient's drainage fluid is abnormal in color, quality, or quantity, or the patient's general condition indicates an infection, or there is a risk of infection at the drainage site, clinical medical staff often need to use aseptic operation techniques to directly retain drainage fluid specimens from the drainage tube for examination and culture, in order to intuitively judge the infection situation and the nature of the source of infection at the drainage site, and provide a basis for subsequent symptomatic treatment. Most drainage tubes in clinical practice do not come with drainage bags, so they require external drainage bags. When collecting specimens, the interface between the drainage tube and the drainage bag needs to be disinfected, and then the connection part is disconnected for specimen collection. The entire operation involves disinfection and disconnection of the pipeline or opening of the drainage fluid discharge port. Drainage fluid may splash at the moment of disconnection or irregular collection may occur due to the belief that the operation is cumbersome.

[0004] If the nature of the infection is clear, and for certain deep drainage treatments, the doctor will temporarily add a flushing line to the part of the patient's body where the drainage tube was originally placed. During the operation, the addition of the line will expand the wound at the drainage tube and cause secondary stimulation, and the line will inevitably touch the surrounding organs and tissues during placement, which will cause pain and discomfort to the patient. The added flushing line may also be displaced or cannot be placed in the ideal position due to the large internal cavity, resulting in unsatisfactory flushing effect. Summary of the invention
