Description
Technical field
This utility model belongs to medical instruments field, specifically is the spiral vacuum blood taking needle of a kind of disposable use.
Background technology
Blood taking needle is a kind ofly to be used for blood sample collection in the medical inspection process, general blood taking needle all is made up of syringe needle and shank, syringe needle is located at the head of shank, slidely connect sheath on shank, the initial position that is provided with back-moving spring and sheath between sheath and shank is positioned at the head of syringe needle and shank.When the hand-held needle tubing of operator is pushed the blood taking needle head on patient's limbs, sheath indentation under the elastic force effect of skin, syringe needle is protruded and thrust skin and cause Wicresoft, sheath resets again under the effect of back-moving spring syringe needle is covered to avoid syringe needle to expose contaminated or the accidental puncture human body after pulling out blood taking needle.When blood taking needle was pulled out, needle tubing and cavity that skin encloses increased gradually, formed instantaneous negative pressure, helped the collection of blood sample.But existing common blood taking needle is in clinical use, fill between the needle stand with thorn because of the blood sampling needle stand sometimes and cooperate the not firm phenomenon that the cooperation place oozing of blood occurs, needle stand cements with bonding agent with thorn plug needle stand if will take a blood sample, perhaps can avoid above-mentioned oozing phenomenon to a certain extent, but want during clinical use blood sampling one end of blood taking needle taken off when using it for anything else and just can not realize that therefore operation is very inconvenient.
The utility model content
The purpose of this utility model overcomes above-mentioned deficiency, and a kind of simple to operate, the spiral vacuum blood taking needle of disposable use that can effectively avoid oozing phenomenon is provided.
The technical scheme that this utility model is adopted in order to achieve the above object is:
The spiral vacuum blood taking needle of disposable use; it guarantees that by the needle tubing of taking a blood sample, blood taking needle sheath, needle handle, flexible pipe, preceding thorn plug needle stand, back thorn are filled in needle stand, thorn fills in needle tubing and haemostatic sheath is formed; described blood taking needle protection of pipe cover covers on blood taking needle pipe front end; the blood sampling syringe rear end connects needle handle, flexible pipe, preceding thorn plug needle stand, back thorn plug needle stand and Ci Sai needle tubing successively; thorn plug needle tubing is provided with haemostatic sheath, it is characterized in that described back thorn plug needle stand inwall is provided with screw thread.Thorn plug needle stand is to be threaded with back thorn plug needle stand before described.
This utility model changes common thorn plug needle stand into spiral thorn plug needle stand, the blood sampling needle stand is filled in thorn and is cooperated firmly (also not needing with bonding agent bonding) between the needle stand, thereby avoided the phenomenon of blood sampling needle stand with thorn plug needle stand cooperation place oozing of blood, load and unload also fairly simple when using so clinically between blood sampling needle stand and the thorn plug needle stand, blood sampling one end of blood taking needle also can be taken off with the supporting human vein that is used in of transfusion device and infuse simultaneously, provides great convenience to medical personnel.Therefore the utlity model has simple in structure, easy to operate, prevent that oozing phenomenon from taking place, low cost and other advantages, have favorable economic benefit, be worth being extensive use of, promoting.
