Abstract
A disposable test-tube blood taking needle pertains to the technical field of the medical devices. The utility model is composed of a needle head (1), a connector (3), a test tube (3), a rubber piston (4) and a push rod (5). The utility model is characterized in that: the upper end of the connector (2) is inserted into a needle seat of the needle head (1) closely, the lower end of the connector (2) is connected with the test tube (3) to a whole body through an inner screw on the inner wall of the connector and an outer screw on the upper end outer wall of the test tube (3), and the push rod (5) is elastically connected with the rubber piston (4) in the test tube (3) through a through hole (6) which is arranged on the bottom of the test tube (3).The utility model has the advantages of that: the blood does not need to be transferred to other test tubes after taking the blood samples, thus to reduce the chances of blood splash, which is not only conductive to the environmental protection, but also conductive to the health of the operators; the blood samples can directly be submitted for tests without the need of other test tubes, thus to save the costs of blood tests; and the outer wall of the test tube is provided with a ring-shaped convex circle, which is conductive to the operation of the medical staff.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to a kind of disposable test tube blood taking needle.
Background technology
The used normally a kind of disposable syringe of blood taking needle of present blood sampling, disposable syringe is made up of syringe needle, syringe, rubber piston, push rod and ears baffle plate.Rubber piston is contained in the syringe, and slides at the inwall of syringe, and with the inner wall sealing of syringe, the ears baffle plate is installed in the bottom of syringe, push rod firmly is connected with rubber piston, and passes the ears baffle plate.There are two kinds of shortcomings in this kind structure: the one, behind blood sample collection, must transfer to chemical examination usefulness to blood sample in vitro again, and can chemically examine blood sample collection; The 2nd,, blood takes place easily spatter outward when test tube shifts blood sample at syringe, cause environmental pollution and, directly have influence on medical personnel or other staff's healthy problem personnel's infection on every side.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned two kinds of shortcomings that disposable syringe exists when blood sample collection, promptly must cause outside the blood easily in test tube shifts blood sample and shifts and spatter, and a kind of disposable test blood sampling tube pin is provided.
This utility model is achieved in that this disposable test blood sampling tube pin is made of syringe needle, joint, test tube, rubber piston, push rod, upper end of joint closely is sleeved in the needle stand of syringe needle, the joint lower end is connected as a single entity by external screw thread and the test tube on female thread on its inwall and the test tube upper end outer wall, and the through hole that push rod passes the test tube bottom is connected with invisible spectro rubber piston elasticity.Invisible spectro rubber piston can slide at the inwall of test tube, and with the inner wall sealing of test tube.The diameter of test tube bottom through-hole is drawn out test tube less than the diameter of rubber piston to prevent piston.Be provided with a plurality of annular bead on the test tube outer wall uniformly, firm stable when annular bead is convenient to use middle finger and forefinger holding test tubes when blood sampling.
When specifically using this utility model, can extract blood by the operational approach of syringe, after blood draw is finished, the pulling push rod, make rubber piston arrive the test tube bottom, because rubber piston is that elasticity is connected with push rod, the diameter of test tube bottom through-hole is less than the diameter of piston, can smoothly push rod be pulled out test tube, rubber piston is sealed in the test tube bottom.And then lay down the joint that the test tube upper end has syringe needle, disposable test blood sampling tube pin just becomes the test tube of a splendid attire blood sample like this, test tube can be directly used in chemical examination and use.
Advantage of the present utility model: do not need later on blood is transferred to other in vitro again having gathered blood sample, reduced the chance that blood spatters outward, promptly help environmental conservation, help operator's health again; Because not needing to dispose test tube just can directly inspect by ready samples again, has saved the cost of blood testing; The test tube outer wall is provided with annular bead, helps medical worker's operation.
Description of drawings
Accompanying drawing is the longitudinal sectional view of this utility model along centrage.
The specific embodiment
Make this utility model with reference to accompanying drawing: this disposable test blood sampling tube pin is made of syringe needle 1, joint 2, test tube 3, rubber piston 4, push rod 5, joint 2 upper ends closely are sleeved in the needle stand of syringe needle 1, joint 2 lower ends are connected as a single entity by external screw thread and the test tube 3 on female thread on its inwall and the test tube 3 upper end outer walls, and the through hole 6 that push rod 5 passes test tube 3 bottoms is connected with rubber piston 4 elasticity in the test tube 3.Rubber pistons 4 in the test tube 3 can slide at the inwall of test tube 3, and with the inner wall sealing of test tube 3.The diameter of test tube 3 bottom through-holes 6 is drawn out test tube 3 less than the diameter of rubber piston 4 to prevent rubber piston 4.Be provided with a plurality of annular bead 7 on test tube 3 outer walls uniformly, firm stable when annular bead 7 is convenient to use middle finger and forefinger holding test tubes 3 when blood sampling.
Claims (3)
1, a kind of disposable test blood sampling tube pin, constitute by syringe needle (1), joint (2), test tube (3), rubber piston (4), push rod (5), it is characterized in that joint (2) upper end closely is sleeved in the needle stand of syringe needle (1), joint (2) lower end is connected as a single entity by external screw thread and the test tube (3) on the outer wall of the female thread on its inwall and test tube (3) upper end, and interior rubber piston (4) elasticity of the through hole (6) that push rod (5) passes test tube (3) bottom and test tube (3) is connected.
2, disposable test blood sampling tube pin according to claim 1 is characterized in that the diameter of the diameter of test tube (3) bottom through-hole (6) less than rubber piston (4).
3, disposable test blood sampling tube pin according to claim 1 is characterized in that being provided with a plurality of annular bead (7) uniformly on test tube (3) outer wall.
