Description
Technical field
This utility model relates to a kind of vein blood taking needle, particularly a kind of observe blood back, needle stand can connect the novel vein blood taking needle of hard pin and transfusion needle flexible pipe respectively, belongs to medical instruments field.
Background technology
Blood taking needle is a kind of common medical appliance, is divided into hard pin and soft pin usually.Hard pin comprises: thorn plug syringe needle, rubber fluid stopping cover, needle stand, lancet head, protective sleeve.Soft pin comprises: thorn plug syringe needle, rubber fluid stopping cover, needle stand, female Luer, flexible pipe, handle, lancet head, protective sleeve.Wherein hard pin puncture needle and needle for inserting bottle are one, needle stand is opaque, whether successful during venipuncture, can only by rule of thumb and feel, in case puncture is unsuccessful, after needle for inserting bottle thrust in the vacuum test tube, the vacuum that will reduce blood taking tube made it to scrap, not only increase medical personnel's work, return patient and cause suffering.Soft pin is more owing to part, and more multi-link and bonding position is arranged, and production cost is higher, and manufacture difficulty is bigger etc.On March 1st, 2006, Patent Office of the People's Republic of China discloses the patent (patent No.: 200420087744.3) of " disposable visual blood back vein blood taking needle " by name, this blood taking needle comprises two-way pin, transparent needle handle, blood back filter element, fixed connecting piece and rubber resilience sheath, two-way pin and transparent needle handle are glued, the blood back filter element is connected with transparent needle handle rear end, and is closely fixing by fixed connecting piece again.Leave the blood back gap between the inboard of fixed connecting piece and the two-way pin.Between the inboard at transparent needle handle rear portion and two-way pin, leave the blood back cavity.The rear portion of fixed connecting piece is connected with the resilience sheath.This utility model has solved the problem that blood back is can't see in vacuum blood drawing technique puncture when operation, but still have more connection and adhesion position, production cost height, manufacture difficulty are big, and this utility model and soft pin are not got in touch, will scrap fully after using once, cause the waste of resource.
Summary of the invention
Improved the success rate of blood sampling puncture, reduced patient's misery, avoided effectively simultaneously because the unsuccessful conflict between doctors and patients that causes of blood sampling.
This utility model is big for solving prior art medium-sized vein blood taking needle manufacture difficulty, and the defective of production cost height and waste resource provides a kind of novel vein blood taking needle.This utility model in visible blood-flow, hard pin and the shared a kind of needle stand of soft pin.
The technical solution of the utility model realizes by following content:
A kind of novel blood taking needle, comprise thorn plug syringe needle, rubber fluid stopping cover, needle stand, lancet head, protective sleeve, described rubber fluid stopping cover is connected with needle stand, thorn plug syringe needle, rubber fluid stopping cover, needle stand and lancet head all are positioned at rubber fluid stopping cover, it is characterized in that: described needle stand is transparent needle stand, and described thorn plug syringe needle is fixedlyed connected with needle stand one end, and the lancet head is connected with the needle stand other end by the lancet joint; Be provided with and sting the observation window that plug syringe needle and lancet head are communicated with in the needle stand; The hose diameter of described lancet joint diameter and soft pin adapts.
Described rubber fluid stopping cover is connected with the spiral basilar part of the needle stand of needle for inserting bottle outer end root.
Described protective sleeve is fastened by two tubular articles and forms, and its fastening place diameter and needle stand diameter adapt, and protective sleeve is by being fixed therein blood taking needle to the fixing of needle stand.
Described observation window is the column hollow part, is located at the middle part of transparent needle stand.
Described protective sleeve (9) is made by hard material.
This utility model makes improvements on the basis of existing technology, brings tangible technique effect, is in particular in following aspect: 1, overall structure is made of thorn plug syringe needle, rubber fluid stopping cover, needle stand, lancet head, protective sleeve, and is simple in structure, easy to make; 2, needle stand is transparent needle stand, be provided with and sting the column hollow observation window that plug syringe needle and lancet head are communicated with in the needle stand, red blood is shown in observation window, solved the problem that blood back is can't see in vacuum blood drawing technique puncture when operation, both improved the success rate of puncture, reduced the waste of product, also reduced patient's misery, increased work efficiency; 3, rubber fluid stopping cover is connected the needle for inserting bottle, the blood taking needle that are used to protect wherein and is fixed in the protective sleeve of being made by material made in Great Britain and is protected with the spiral basilar part of the needle stand of needle for inserting bottle outer end root, and design science is reasonable; 4, the hose diameter of lancet joint diameter and soft pin adapts, the lancet joint both can link lancet and be used to make hard pin, also can make soft pin by bonding flexible pipe, hard pin and soft very shared thorn plug syringe needle, rubber fluid stopping cover, transparent needle stand and lancet joint, reduce the making of mould, greatly reduce production cost.
