Abstract
A disposable test tube blood collection needle belongs to the technical field of medical devices and comprises a test tube, a test tube cap, a piston and a pull rod. The blood collection needle is characterized in that the test tube cap with a puncture needle head at the front end is sleeved in a sealed manner on the outer wall of an open end of the test tube with anti-slip stripes on the outer wall thereof, two limit ribs corresponding to two axial grooves on the inner wall of the test tube are symmetrically arranged on the side wall of the piston connected with the inner wall of the test tube in a sliding and sealed manner, a sleeve pipe with threads on the inner wall is fixed inside a groove in the center of the rear end surface of the piston, and the front end of the pull rod is in threaded connection with the sleeve pipe after penetrating a through hole at the bottom of the test tube. The blood collection needle has the advantages of simple structure and simple and convenient operation; and as blood can enter the test tube directly, the blood collection needle reduces blood contamination and avoids the damage on blood sample cells.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of disposable test blood sampling tube pin.
Background technology
At present, manually gather blood and adopt split type hemostix usually, both utilized syringe class hemostix that blood is extracted out, and then moved in the test tube.This traditional approach formality is loaded down with trivial details, operation inconvenience; When blood sample is moved into test tube, blood is spattered outward, cause environmental pollution and to personnel's infection on every side, the blood sample cell is also destroyed easily simultaneously.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of blood of gathering can directly enter test tube, and the blood sample cell can not suffer destructive disposable test blood sampling tube pin.
The purpose of this utility model is achieved in that this disposable test blood sampling tube pin is made of test tube, cap test tube, piston, pumping rod, outer wall is provided with the test tube opening end outer wall sealing suit of anti-skidding striped and the cap test tube that front end is provided with piercing needle, be provided with two retaining convex ribs that adapt with two axial notches of inboard wall of test tube with symmetric on the piston side wall that the inboard wall of test tube slipper seal is connected, the groove internal fixation of piston rear end face center the sleeve pipe that inwall is provided with screw thread, and the through hole that the pumping rod front end passes above the test tube bottom is connected with casing threads.
After the lancet puncture success, the pulling pumping rod can be adopted blood into test tube, and after blood sampling finished, the rotation pumping rod can be laid down pumping rod above piston, pull out cap test tube at last and just blood directly can be inspected by ready samples.
Advantage of the present utility model: simple in structure, easy and simple to handle, blood can directly enter test tube, can reduce blood contamination, avoids the blood sample cell to be destroyed.
Description of drawings
Accompanying drawing is a structure cutaway view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail: this disposable test blood sampling tube pin is by test tube 1, cap test tube 2, piston 3, pumping rod 4 constitutes, outer wall is provided with the test tube 1 opening end outer wall sealing suit of anti-skidding striped and the cap test tube 2 that front end is provided with piercing needle 5, be provided with two retaining convex ribs 7 that adapt with two axial notches 6 of test tube 1 inwall with symmetric on piston 3 sidewalls that test tube 1 inwall slipper seal is connected, the groove internal fixation of piston 3 rear end face centers the sleeve pipe 8 that inwall is provided with screw thread, and the through hole that pumping rod 4 front ends pass above test tube 1 bottom is threaded with sleeve pipe 8.
