Abstract
The utility model discloses a double-needle puncturing and plugging system of an instant vacuum blood collection device. The double-needle puncturing and plugging system comprises a needle head holder, a lifting controller, a bi-directional needle-handle-provided blood collection needle, a puncturing and plugging needle head, an exhaust needle, a vacuum-free test tube and a blood collection needle clamping device. According to the system, the vacuum-free test tube is positioned in a test tube rack; the package of the blood collection needle is torn off; the puncturing and plugging needle is arranged on the needle head holder; a start-up switch is started; the lifting controller is used for reducing the pressure; the puncturing and plugging needle and the exhaust needle simultaneously prick into a test tube plug; a blood collection button is pressed down; a negative pressure pump is started, and vein puncturing for blood collection can be performed after the test tube is filled with negative pressure; when the blood collection is finished, a stop button is pressed down; and the blood collection needle is pulled out, and the blood collection process can be finished. The double-needle puncturing and plugging system of the instant vacuum blood collection device has the advantages of convenience and quickness, and can improve the work efficiency.
Description
Affiliated field
This utility model relates to a kind of automatic blood sampling equipment, relates in particular to the instant vacuum blood collection equipment that a kind of hospital chemical examination blood uses.
Background of invention
The development of making rapid progress along with economy and the raising of living standards of the people, people's self health consciousness strengthens day by day, people's increasing year by year of health examination.Venous blood collection is requisite big event in health examination, because the examinee requires more and more highlyer to the success rate of venipuncture blood sampling, nurse's operating technology has also been proposed higher requirement.Medical examiner's age differences is larger, the having of all age group, and the maximum old people who has more than 80 year old, minimum have a child how old.No matter old man, adult, or child because the situation of vein blood vessel is different, have increased difficulty for the success of nurses collecting blood, therefore require the nurse to have consummate operating technology by Shall.So large workload causes most of nurses all to produce intense strain, also has the outpatient service Blood Sampling Room at large hospital, and queuing time is long, patient's mood is irritable, make every effort to hit the nail on the head, avoid repeated localised puncture, nurses urgently wish a kind of fast, blood sampling apparatus comes out easily.
In order to seek a new blood-sampling method and equipment, the inventor had once applied for " airtight negative-pressure automatic hemostix device " patent No. 99214075.7 " totally-enclosed negative pressure hemostix " patent No. 95245460 " airtight negative-pressure automatic hemostix device " number of patent application 98112817[publication number]: 1225809.Owing to adopting manually thorn plug scheme, operate not too convenient.This utility model has increased automatic Ci Sai system on original basis.
The invention scheme
In order to reach automatic thorn plug purpose, this utility model adopts following technical proposals:
A kind of double needle Ci Sai system of instant vacuum blood collection equipment is by needle head fixer 1, lifting controller 2, two-way tape needle handle blood taking needle 3, thorn plug pin 4, the pin 5 of bleeding, stop device 7 without vacuum test tube 6, blood taking needle vessel clamp and formed.The feature of needle head fixer 1 is the bracing frame of rectangular type structure, in positive and side respectively with two of the preformed holes of the same length of needle handle of two-way tape needle handle blood taking needle 3 and width, can be respectively the needle handle of the needle handle of two-way tape needle handle blood taking needle 3 and the pin 5 of bleeding be inserted in separately hole, fixed installation two-way tape needle handle blood taking needle 3 with bleed pin 5 on needle head fixer 1.Also be provided with the blood taking needle vessel clamp and stop device 7 on needle head fixer 1, but it is characterized in that being made of the clip of folding, the conduit of blood taking needle passes from the centre, can clamp conduit and stop blood to flow out when it is closed.The end of pin 5 of bleeding is connected with the syringe needle with needle handle, is arranged on during use on needle head fixer 1, and other end needleless is connected with negtive-pressure implement by plastic catheter.Lifting controller 2 is liftable devices of a connection instrument and needle head fixer 1, is connected with needle head fixer 1 with fastened by screw, coordinates with Mechatronic Systems to realize controlling the thorn plug of syringe needle and extracting.Two-way tape needle handle blood taking needle 3 respectively connects a syringe needle with needle handle by plastics flexible catheter two ends and is formed, and a terminal spine enters in blood vessel, and the other end is arranged on needle head fixer 1 in use for thorn plug pin 4, the needle handle of thorn plug pin 4.Formed by cap test tube, test tube plug and test tube without vacuum test tube 5, it is characterized in that in vitro without vacuum, during use and this coordinative composition of equipments use, automatically produce negative pressure by instrument blood introduced in vitro.The present invention can set up automatic replace tubes, automatic mixing, automated optical and quantitatively, automatically discharge the functions such as remaining negative pressure in implementation process, strengthen its result of use.
The utility model has the advantages that: 1, band negative pressure needling, blood back is obvious, is easy to judge the puncture situation.2, the common plastics test tube can be used, and saves the blood sampling cost.3, blood sampling speed is fast, is fit to outpatient service and health check-up and takes a blood sample in enormous quantities.4, adopt without vacuum test tube, utilize instant vacuum technique, vacuum magnitude is adjustable, adapts to the different situations blood sampling.5, prevented that negative pressure is not enough or occured without the problem of negative pressure.6, discharge immediately remaining negative pressure after the blood sampling, solve in vitro negative pressure residue problem.7, negative pressure is constant, has solved vacuum test tube starting stage negative pressure large, subsequently the problem that reduces gradually of negative pressure.8, solved due to the height above sea level difference the in vitro impact of vacuum.
Description of drawings
Fig. 1 is structure of the present utility model and connection diagram, the 1st, and needle head fixer, the 2nd, lifting controller, the 3rd, two-way tape needle handle blood taking needle, the 4th, thorn plug syringe needle, the 5th, the pin of bleeding, the 6th, without vacuum test tube, the 7th, the blood taking needle vessel clamp stops device.
The specific embodiment
Needle head fixer is arranged on lifting controller, then lifting controller is fixed on tool housing.The needle handle of pin of bleeding is arranged on a side of needle head fixer.Putting into test tube rack without vacuum test tube, tear the blood taking needle packing, will sting the plug pin and be arranged on needle head fixer, open starting switch, lifting controller presses down, and thorn plug pin and the pin of bleeding thrust in test tube plug simultaneously.Press the blood drawing key, negative pressure pump starts, and begins the venous blood collection that punctures after in vitro being full of negative pressure.Take a blood sample complete, press stop key, negative pressure pump shuts down, and extracts blood taking needle, takes a blood sample complete.
