Neurological sampling device

Abstract

A neurological sampling device comprises a U-shaped frame, a barrel, a handheld handle, a driving shank, a liquid storage bottle and a puncture needle. The barrel is arranged in the U-shaped frame, asuction tube and a one-way exhaust valve are arranged at one end of the barrel, a piston is arranged in the barrel, and a reciprocating spring is arranged between the piston and one end, with the suction tube, of the barrel. A transmission rod is arranged at the other end of the piston and extends out of the barrel to connect with a transmission connecting rod through a second rotating fastener. One side of the U-shaped frame is connected with the handheld handle through a linkage rod, the driving shank is arranged at the end of the transmission connecting rod, a connection tube is arranged atthe lower end of the suction tube, and the tail portion of the connection tube is connected with a flow guide tube through an anti-shedding mechanism. A conical end is hermetically connected with theflow guide tube, an annular cavity is formed between the outer wall of the flow guide tube and the interior of an outer sleeve, a pressure meter is arranged on the upper side of the suction tube, thepuncture needle is arranged at the front end of the suction tube, and the outer side of the suction tube is provided with a disposable sterilization cap. The neurological sampling device is simple instructure and convenient to use, pressure detection and sampling can be completed in one time, and cerebrospinal fluid sample contamination is avoided due to airtightness in a submission process.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a neurology specimen sampler. Background technique [0002] Clinically, when treating neurological diseases, it is usually necessary to perform cerebrospinal fluid pressure measurement and sample sampling on patients. The commonly used clinical cerebrospinal cord sample sampling device is generally a sterile catheter connected to a puncture needle and a pressure gauge. First, the pressure of the cerebrospinal fluid is measured through the pressure gauge, and then the puncture is used to sample the cerebrospinal fluid. The operation is troublesome and time-consuming. It is laborious and causes pain to the patient. In addition, the liquid inlet of the storage bottle is directly exposed during the inspection process, especially in the process of pouring out the cerebrospinal fluid sample, which may easily cause sample contamination.
