Abstract
The utility model relates to a pre-negative pressure suction type deep part arteriovenous guide wire implantation device. The prior vein implantation technologies at home and abroad have the problems of low puncture accuracy and great operation difficulty, the technology mastery is difficult for the medical staff and the patients are inflicted by injury. The utility model aims to design the pre-negative pressure suction type deep part arteriovenous guide wire implantation device with excellent puncturing effect, high accuracy, easy operation and automatic blood suction. The device comprises a needle head, a needle head connecting sleeve, a piston sleeve and a piston inner core and adopts a negative-pressure automatic suction mode, whererin, a negative pressure switch is arranged on the puncture needle head connecting sleeve and a spring plate lock is arranged on the inner core of a suction device to ensure the formation of negative pressure in the piston. The device has the advantages of reasonable design, excellent accuracy and fine automatic suction effectiveness.
Description
Technical field:
This utility model belongs to medical apparatus, is specifically related to a kind of pre-negative pressure suction type deep artery venous silk-guiding introducing device.
Background technology:
Existing domestic and international venous duct is inserted the technology ubiquity, and the puncture accuracy rate not high, damage to patient is big, complication is many, the time that conduit is inserted falls short of, operation easier is big, be difficult for grasping, thereby popularity rate is not high, so that most of medical worker is difficult to grasp this technology, the treatment opportunity that also increases misery and influence patient to patient simultaneously.
Summary of the invention:
The purpose of this utility model is to provide a kind of easy for operation, accuracy is high, sterile working's property is strong pre-negative pressure suction type deep artery venous silk-guiding introducing device according to above-mentioned weak point.Can draw blood automatically, can finish puncture suction by one hand, but and inserting needle blood drawing and withdraw of the needle blood drawing, improved puncture success rate, reduce damage and patient's complication, simplified operating technology simultaneously, alleviated medical workers, improve the medical skill effect.
This utility model is to realize like this, this device is made of syringe needle, syringe needle adapter sleeve, piston bush, piston inner core four parts, and it adopts the negative pressure auto-pumping, promptly is provided with negative pressure switch on the piercing needle adapter sleeve, on the aspirator inner core, be installed on the shell fragment lock, guarantee that negative pressure forms in the piston.This device is the syringe construction shape, the piston inner core is installed in piston bush, the piston inner core is provided with piston inner core shell fragment lock, the central authorities of piston inner core are provided with piston inner core silk guide passage, be provided with seal wire intake and seal wire in the middle of the push rod of piston inner core tail end and introduce sealing gasket, even locate to be provided with the syringe needle adapter sleeve at the front end and the syringe needle of piston bush, the syringe needle adapter sleeve is provided with the negative pressure switch valve, syringe needle adapter sleeve front end is connected with syringe needle, and the rear end is connected with piston bush by switch valve.

Figure grade:
Syringe needle 1, syringe needle adapter sleeve 2, piston bush 3, piston inner core 4, puncture needle body 11, syringe needle connecting hole 12, syringe needle union joint 21, negative pressure switch valve 22, switch valve piston union joint 23, piston switch valve union joint 31, piston bush 32, seal wire inlet tube 33, piston inner core sealing ring 41, piston inner core silk guide passage 42, piston inner core shell fragment lock 43, seal wire are introduced sealing gasket 44, seal wire intake 45.
The specific embodiment:
Pre-negative pressure suction type deep artery venous silk-guiding introducing device of the present utility model, it constitutes single unit system by syringe needle 1, syringe needle adapter sleeve 2, piston bush 3, piston inner core 4 four parts, syringe needle adapter sleeve 2 at puncture needle is installed on negative pressure switch 22, is installed on shell fragment lock 43 on the piston inner core 4 of aspirator.
It forms the negative pressure auto-pumping, its operation principle, when the negative pressure switch valve 23 of cutting out on the syringe needle union joint 22 makes piston 3 intracavity be the sealing state pinning, post-tensioning piston inner core 4 to inner core shell fragment lock 43 pins again, established negative pressure in the holding chamber, then syringe needle is thrust tissue and open negative pressure switch 22, negative pressure is aspirated, when piston bush 3 intracavity negative pressure-pumpings behind blood, promptly hold inserter in resting state, introduce 45 places, hole at the inner core seal wire again and insert seal wire in the lumen of vessels that is punctured, keep seal wire then in blood vessel, dial and remove inserter, finish seal wire and insert in the lumen of vessels.
This utility model is the syringe construction shape, piston inner core 4 promptly is installed in piston bush 3, piston inner core 4 is provided with piston inner core shell fragment lock 43, the central authorities of piston inner core 4 are provided with piston inner core silk guide passage 42, be provided with seal wire intake 45 and seal wire in the middle of the inserted link of piston inner core tail end and introduce sealing gasket 44, front end and syringe needle junction at piston bush 3 are provided with syringe needle adapter sleeve 2, syringe needle adapter sleeve 2 is provided with negative pressure switch valve 22, syringe needle adapter sleeve 2 front ends are connected with syringe needle 1, and rear end and piston bush 3 are connected to form single unit system.
