Urinary calculus sampling device

Abstract

The invention discloses a urinary calculus sampling device, and relates to the technical field of calculus sampling devices. The device comprises a flow guide pipe, the flow guide pipe comprises a top section and a bottom section which are vertically arranged, and a middle section which is obliquely arranged; a sealing air bag is arranged in the runner pipe; a sampling test tube is hermetically inserted into the outer wall of the runner pipe; the inner bottom end of the sleeve is fixedly sleeved with a filter screen; the outer wall of the top section of the flow guide pipe is fixedly connected with a grip; a filling air bag is arranged in the inserting groove, and a button is inserted into the inserting groove in a sliding mode. The urine sampler has the beneficial effects that when urine is guided by the flow guide pipe and filtered by the filter screen to separate and collect stones, the sealing air bag seals the circulating pipe to enable the urine to flow smoothly, and when the urine is sampled, the inclined middle section of the flow guide pipe enables the urine to flow more intensively, so that the urine sampling efficiency is improved. After the sealing air bag is contracted, the sampling urine section flows into the sampling test tube through the circulating pipe for collection, urine of other urine sections is filtered to collect calculi, and the calculus collecting device is flexible, convenient and efficient to use.

Description

technical field [0001] The invention relates to the technical field of stone sampling devices. Background technique [0002] Stones are solid blocks formed in the catheter lumen or luminal organ cavity in the human body. Traditionally, patients are treated by extracorporeal lithotripsy, and extracorporeal lithotripsy generates shock waves through an extracorporeal lithotripsy machine, which is focused by the machine and then treated. Quasi-stones, after multiple releases of energy, crush the stones in the body and make them excreted with urine; [0003] When stones are excreted with urine, it is necessary to sample the stones in order to analyze the type of stones. Traditionally, beakers are used to hold the urine and wait for the stones to settle in order to collect them. Therefore, the urine that needs to be collected when collecting stones Large liquid capacity, time-consuming use and lower stone collection efficiency, and urine collection for certain periods of time is ...

[0003] When stones are excreted with urine, it is necessary to sample the stones in order to analyze the type of stones. Traditionally, beakers are used to hold the urine and wait for the stones to settle before collecting them. Therefore, the urine that needs to be collected when collecting stones Large liquid capacity, time-consuming use and lower stone collection efficiency, and urine collection for certain periods of time is required when collecting stones, so urine collection is required for stones throughout the process, and urine samples need to be collected for a certain period Sampling the middle of the urine, which causes conflicts between urine sample collection and stone collection, so the use of traditional beakers has limitations
