Description

Technical Field

[0001] This utility model relates to the technical field of convenient sampling devices for eribulin drug detection, and in particular to a convenient sampling device for eribulin drug detection. Background Technology

[0002] The existing patent publication number (CN221123944U) discloses a drug detection sampling device, including a base, a drug storage cylinder in contact with the base, an installation mechanism shared by the drug storage cylinder and the base, a support frame fixedly connected to the base, a cylinder fixedly mounted on the support frame, a guide plate fixedly connected to the extension end of the cylinder, a guide plate slidably connected to the support frame, an installation shell fixedly connected to the guide plate, and a sampling mechanism mounted on the installation shell. This invention, through the combined use of a motor, threaded rod, and other structures, can drive a moving rod to move a piston disc, thereby enabling the sampling tube to draw and sample the drug solution. Furthermore, with the assistance of structures such as locking holes and locking balls, the displacement of the piston disc can be limited, thus precisely controlling the amount of drug solution drawn.

[0003] However, in the process of drug testing, the dosage of the drug solution only needs to be within a reasonable error range. What is actually needed is how to quickly distribute the drug into the test tubes for testing. The aforementioned patented equipment can only sample one by one, which is inefficient.

[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0005] A convenient sampling device for iribulin drug detection includes a cylindrical rod with a drug-containing cavity inside the rod, and a sealing piston that cooperates with the cavity. The volume of the drug-containing cavity is changed by moving the sealing piston.

[0006] The dispensing tube is connected to the cylinder rod and a one-way valve is provided at the connection point. A hose connector is provided on the side of the cylinder rod, and the hose connector is connected to the medicine bottle through a hose.

[0007] The dispensing tube is equipped with dispensing nozzles at intervals for discharging medicine;

[0008] An automatic reset press is located on the upper end of the piston, and the lower end of a portion of its components abuts against the upper end face of the cylinder rod.

[0009] Preferably, the automatic reset press includes a push rod with a tail end fixed at the upper end, and a reset spring. The two ends of the reset spring abut against the upper end face of the cylinder rod and the lower end face of the tail end, respectively, so that the push rod is pushed upward by the reset spring.

[0010] Preferably, the side of the cylinder is fixed with a handguard for easy gripping.

[0011] Preferably, the dispensing tube has an integrally formed neck in the middle, and the neck and the lower end of the cylinder are connected by a threaded seal.

[0012] Preferably, a first one-way valve is embedded in the neck of the tube, and the flow direction of the first one-way valve is from the inside of the cylinder to the inside of the dispensing tube.

[0013] Preferably, the hose connector is equipped with a one-way valve, and the flow direction of the one-way valve is from the outside of the cylinder to the inside of the cylinder.

[0014] The advantages and positive effects of this utility model are:

[0015] 1. The structure is simple and the sampling and dispensing are convenient. The tube is connected to the medicine through a flexible tube. The reciprocating motion of the push rod with a piston and the cooperation of two one-way valves transfer the medicine into the tube. Then, the medicine is dispensed into the sample tube through the medicine dispensing nozzle. It is very convenient and fast. In addition, the medicine bottle is in a closed state, which is more scientific and reasonable. Attached Figure Description
