AI Technical Summary
Technical Problem
Existing urine collection devices require disinfection of the sampling site proximal to the catheter before collecting urine samples, which poses a risk of incomplete disinfection and needlestick injury.
Method used
A urine collection device including a fixing mechanism and a sealing mechanism was designed. The catheter is fixed by a clamp and adhesive strip to avoid the disinfection step, and the collection cylinder is sealed by a sealing cap and an internal threaded sleeve to prevent external air pollution.
Benefits of technology
This technology enables the safe collection of urine samples without the need for sterilization, reduces the risk of needlestick injuries, and effectively prevents external air pollution, thus improving the safety and ease of operation.

Abstract
The utility model relates to the technical field of medical instruments, in particular to a urine collecting device collected through a catheter, which comprises a collecting barrel, a barrel cover is mounted at the top of the collecting barrel, a fixing mechanism is arranged at the top of the barrel cover, and a sealing mechanism is arranged at the top of the barrel cover and above the fixing mechanism. The fixing mechanism comprises a connecting sleeve fixedly connected to the top of the collecting barrel, a clamping block is slidably connected to the interior of the connecting sleeve, and an extrusion block is slidably connected to the outer wall of the clamping block and located in the connecting sleeve. By means of the design that a clamping plate and an adhesive tape in the fixing mechanism enable the clamping plate to clamp an inserted catheter through a pushing structure, the problems that according to an existing catheter collecting device, the outer wall around a sampling part at the near end of the catheter needs to be disinfected firstly, and then an injector is directly used for puncturing into a catheter cavity to collect urine; the sampling part cannot be thoroughly disinfected, and the risk of pricking injury is high.
