Description

Drainage bag convenient for reserving and taking samples

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a drainage bag convenient for reserving and taking a specimen.

Background

The conventional disposable drainage bag can be used for drainage and storage of urine, thoracic drainage liquid, peritoneal drainage liquid, bile and other liquids of patients in clinic. After the disposable drainage bag is removed from the outer package, the protective cap on the drainage tube connector is pulled out, the connector of the drainage tube is connected with the external interface of the catheter or other pipelines of the patient, and then the upper end of the drainage bag is fixed.

At present, the drainage bag has the following defects in clinical use: ① When urine samples or other drainage liquid samples are required to be obtained by assaying the drainage liquid, the conventional samples are usually obtained from the drainage bag in clinic, and the method can influence the assay result because the samples in the drainage bag have longer time due to the drainage liquid; when a culture specimen needs to be reserved, the drainage tube is pricked into the drainage tube by using the injector after being disinfected to extract the specimen, the drainage tube can be damaged by the method, liquid leakage of the drainage tube can be caused when the drainage tube is severe, and the specimen can be possibly polluted. ② When the urinary catheterization is needed, the bladder is required to be flushed or other drainage is required to be injected, and when the urinary catheterization is needed to be flushed, the bladder flusher is adopted or the transfusion scalp needle is pricked into the catheter to be flushed, so that the operation is complex, and the drainage bag is required to be connected with the bladder flusher after being separated before the bladder flusher is used for flushing the bladder; when the infusion set is used for flushing, the scalp needle is pricked into the catheter, so that the catheter is damaged, the risk of urine leakage exists in the later stage, and meanwhile, the scalp needle also has the risk of pricking a patient. When other drainage needs lavage or medicine injection, after the drainage bag is separated, the lavage or medicine injection is carried out by adopting a lavage device, so that the operation is complex and the pollution is easy. ③ When the drainage amount is measured, the measurement is usually carried out according to the scale on the drainage bag, and when the drainage bag is not fixed or is wrinkled, a large error can exist in measurement. ④ When the drainage bag is used by bedridden patients, the drainage bag is easy to pull out when the drainage bag is fixed beside a bed and turned over.
