Abstract
A kind of disposable blood taking device is to belong to a kind of apparatus that medical inspection is used, and is made up of blood collection needles, trocar sheath, sealing-plug, teat glass, blood transfusion tube, negative pressure pipe.Simple in structure, more more convenient than using blood collection needle, blood sampling, to contain blood and once finish, issuable haemolysis factor when having overcome the blood collection needle injecting tube has improved the accuracy rate of assay, has also avoided the secondary cross infection simultaneously.
Description
The present invention relates to a kind of medical apparatus and instruments one check hemostix, exactly is a kind of novel disposable blood taking device.
Current, glass syringe and plastic injector for temporary use are generally used in the medical inspection blood sampling, and new special use check hemostix people explore and develop.The present invention provides a kind of new disposable blood taking device according to the requirement and the characteristics of medical inspection blood sampling, and it has simple in structure, uses more conveniently, and blood sampling, Sheng blood are once finished, and avoids haemolysis, the characteristics of the secondary cross infection of stopping to take a blood sample.
The object of the present invention is achieved like this, and a kind of disposable blood taking device is made up of blood collection needles, trocar sheath, sealing-plug, teat glass, blood transfusion tube, negative pressure pipe, it is characterized in that: blood collection needles (1) is exactly the ordinary syringe syringe needle; Trocar sheath (2) is basic identical with the ordinary syringe trocar sheath, but body length can be shorter; Trocar sheath (2) front end below is the mastoid process of blood collection needles (1) fixedly, and internal diameter and the external diameter tight fit that extends in interior blood transfusion tube (5) make blood collection needles (1) be satisfied with can directly be communicated with blood transfusion tube (5) on the mastoid process; Rear section seal glass test tube (4) mouth of pipe of sealing-plug (3), teat glass (4) body major part enters in the trocar sheath (2); Blood transfusion tube (5) one ends are communicated with blood collection needles (1), and the other end passes sealing-plug (3) and enters teat glass (4), and blood collection needles (1) is communicated with teat glass (4) by blood transfusion tube (5); The one section crooked front end that contracts in trocar sheath (2) that coils of part that is equivalent to trocar sheath (2) length in the centre of blood transfusion tube (5), when sealing-plug (3) moved in trocar sheath (2) backward along with teat glass (4), the sweep of blood transfusion tube (5) was along with being stretched; Negative pressure pipe (6) passes sealing-plug (3) and enters and reach nearly pipe bottom position in the teat glass (4), and trocar sheath (2) is communicated with teat glass (4) by negative pressure pipe (6); The internal diameter of the forward part of sealing-plug (3) and trocar sheath (2) is sealed and matched, and also can be that the external diameter of teat glass (4) and the internal diameter of trocar sheath (2) are sealed and matched; As the plunger body of suction piston action, the right side is to seesaw in trocar sheath (2) and to extract out fully in trocar sheath (2) for teat glass (4) fitted seal plug (3).
When gathering blood, identical with operating syringe blood sampling vacuuming operation, teat glass (4) combination seal plug (3) in trocar sheath (2) as the plunger body of suction piston action when moving backward, volume in the trocar sheath (2) enlarges the generation negative pressure, act in the teat glass (4) by negative pressure pipe (6), thereby make the blood transfusion tube (5), the blood collection needles (1) that are communicated with teat glass (4) produce suction blood sampling effect.When the blood of gathering reaches the check requirement, extract blood collection needles (1) on one's body from blood count person, in trocar sheath (2), teat glass (4) is extracted out fully, take the sealing-plug (3) of teat glass (4) mouth of pipe, blood sampling, the work of Sheng blood have just been finished.
Advantage of the present invention is: simple in structure, operational approach and injector operations are basic identical, and blood sampling, Sheng blood are once finished, and avoid haemolysis, the secondary cross infection of stopping to take a blood sample.

Embodiment:
Disposable blood taking device with collection check liver function desired blood is an example, blood collection needles (1) is used 7 metal needles, the high pressure polyethylene injection mo(u)lding of trocar sheath (2), sealing-plug (3), blood transfusion tube (5), negative pressure pipe (6), teat glass (4) 12mm X 70mm medical glass test tube.Trocar sheath (2) external diameter 15mm, internal diameter 13mm, long 50mm, the mastoid process part of front end below is identical with simple glass syringe mastoid process specification; Blood transfusion tube (5), negative pressure pipe (6) internal diameter are 0.6mm, long 70mm; Sealing-plug (3) internal diameter 7mm, external diameter 10mm, total length 16mm, first half have two road sealing rings, the external diameter 13mm of ring, wide 1.5mm, spacing 5mm, in sealing-plug (3) internal diameter seal dissepiment is arranged one, thickness 2mm has two apertures to pass for blood transfusion tube (5), negative pressure pipe (6) tight fit on the film.
All the other are knowledge.
Claims (1)
- The disposable blood taking device that a kind of medical inspection is used is made up of blood collection needles, trocar sheath, sealing-plug, teat glass, blood transfusion tube, negative pressure pipe, it is characterized in that:Blood collection needles (1) is installed on the mastoid process of trocar sheath (2) front end below; The mouth of pipe of sealing-plug (3) seal glass test tube (4); Teat glass (4) combination seal plug (3) is sealed and matched with the internal diameter of trocar sheath (2), as the plunger body of suction piston action, can seesaw and extraction fully in trocar sheath (2); Blood transfusion tube (5) passes sealing-plug (3), and blood collection needles (1) is communicated with teat glass (4); Negative pressure pipe (6) passes sealing-plug (3), and trocar sheath (2) is communicated with teat glass (4).
