Specific embodiment
Below in conjunction with attached drawing, lift a specific embodiment and be described in detail.
As shown in Figure 1-Figure 3, a kind of Novel anti-stab hinders precision filter infusion set, including the infusion being sequentially arranged on a hose Needle portion 1, the first locking folder 2, resistance bacterium portion 3, flow regulator 4, precision liquid medicine filter 5, automatic exhaust part 6, dropping funnel 7, second Locking folder 8 and exhaust modeling needle portion 9.Transfusion needle portion 1 includes infuse soft needle 103, implanting needle 102, protective jacket 101, transfusion catheter 104th, barrier plug 105, Anti-stabbing plug 106 and needle stand 107.Soft needle 103 of infusing is made of TPU materials, does not contain plasticizer, It is that country advocates the medical material used.Soft needle 103 of infusing is socketed on implanting needle 102, and the one end for soft needle 103 of infusing is riveted on On the first end of transfusion catheter 104, and connected by transfusion catheter 104 with hose.Infuse soft needle 103 outside be equipped with one A protective jacket 101, the end of protective jacket 101 are socketed in the first end of transfusion catheter 104, using preceding protective jacket 101 to infusion Soft needle 103 has fungi-proofing effect, and when infusion gently pulls out.Implanting needle 102 is made of stainless steel, for puncturing blood It manages and the soft needle 103 that will infuse is imported in blood vessel.The groove 1021 to concave into is provided on implanting needle 102.Implanting needle 102 passes through Transfusion catheter 104, barrier plug 105 and Anti-stabbing plug 106 are worn, and is fixed on needle stand 107.Infusion is formed on transfusion catheter 104 Chamber 1041, the transfusing chamber 1041 connect infuse soft needle 103 and hose, and transfusing chamber 1041 passes through a catheter block with hose junction 108 are connected, with convenient for assembly with dismounting transfusion catheter 104 and hose.Transfusing chamber 1041 close to barrier plug 105, fill in by barrier 105 have guiding and iris action, prevent liquid or blood from flowing to the external world, ensure that liquid enters transfusion catheter 104 from hose Transfusing chamber 1041 after exported by soft needle 103 of infusing, and the blood back generated during contact pin due to pressure by barrier plug 105 gear Firmly without leaking outside.The center of barrier plug 105 is equipped with the first passage of implanting needle 102, has guiding role to implanting needle 102.Resistance Stopper 105 is close to Anti-stabbing plug 106, the second channel for being centrally formed implanting needle 102 of Anti-stabbing plug 106, is set on second channel Have with the groove 1021 matched raised 1061, for blocking implanting needle 102, prevent implanting needle 102 from shaking and stabbing medical care Personnel, the distance of protrusion 1061 to 106 end of Anti-stabbing plug are more than the distance that the groove 1021 arrives 102 end of implanting needle, from And after realizing extraction implanting needle 102, the syringe needle of implanting needle 102 is placed in Anti-stabbing plug 106, i.e., inside second channel.Barrier plug 105 and Anti-stabbing plug 106 be made of rubber material, and be interference fitted respectively with transfusion catheter 104, realize sealing.Needle stand 107 The second end of transfusion catheter 104 is placed on, convenient for extracting implanting needle 102 out.
Precision liquid medicine filter 5 has upper shell, lower housing and filter membrane to form.Upper shell and lower housing interference fit, Filter membrane is arranged in the hollow space that upper shell and lower housing are formed, and affixed from top to bottom three layer filtration film, is used for Filtering liquid medicine.The infusion entrance connected with hose is formed on upper shell, the infusion outlet connected with hose is formed on lower housing.It is defeated During liquid, liquid enters from the infusion entrance on upper shell, and outflow is exported from the infusion on lower housing after membrane filtration.Upper casing Gas vent is provided on body, for the gas being mingled in liquid to be emitted.Accurate filter is more suitable for severe, postoperative patient The crowd lower for the resistance such as person and newborn, because pure liquid is extremely important for this kind of crowd.From the angle of liquid For, the particle number in Chinese medicine preparation is more, and common filter easily generates liquid absorption and influences filter effect, thus Stability is poor, this application involves precision liquid medicine filter 5 solve the problems, such as this by using the form of multistage filtering, so as to It further ensure that the drug safety of patient.
In infusion process, the first locking folder 2 and the second locking press from both sides the 8 pairs of control actions of infusion with open and close, are closing Under state, the first locking folder 2 and the second locking press from both sides the 8 hydraulic pressure 15s for being able to persistently bear 20KPa.
Resistance bacterium portion 3 is connect using public screwed union with hose, and resistance bacterium plug is socketed in the outer ring of junction, for hindering Only external bacterium is entered by public screwed union in liquid.
Automatic exhaust part 6 is set to the upper end of precision liquid medicine filter 5, for discharging the gas in liquid, protects as far as possible The liquid that card enters in precision liquid medicine filter 5 does not contain gas.
Exhaust modeling needle portion 9 includes puncture outfit and the plastic handle and air filter that are connected respectively with puncture outfit, plastics hand The other end connection hose of handle, when use, which need to only puncture, once can be completed out liquid and exhaust, convenient for clinical transfusion bag and infusion Bottle uses.
In use, the puncture portion for being vented modeling needle portion 9 is inserted into infusion bottle or infusion bag, flow regulator 4 is placed on most Big position makes dropping funnel 7 vertical, removes protective jacket 101, and infusion bottle or the liquid level of infusion bag is kept to have 1m with transfusion needle portion 1 Pressure, without hand squeeze dropping funnel 7, liquid is freely arranged down.With visual observation, the bubble generated in discharge opeing process is entering precision It has been discharged before liquid medicine filter 5, has alleviated the troublesome operation that nursing staff comes for vent strip.After liquid dredging, it will flow Measure adjuster 4 adjust to minimum, be then introduced into needle 102 be inserted into patient vessel in, infuse soft needle 103 with implanting needle 102 into Enter blood vessel, then slowly extracted implanting needle 102 by needle stand 107, until the protrusion 1061 on Anti-stabbing plug 106 is caught in importing In groove 1021 on needle 102.The flow velocity of liquid is adjusted to suitable state by adjustment flow regulator 4 again.
In the utility model, soft needle 103 of infusing is made of TPU materials, and has certain flexibility, and hose uses TPE material, TPU and TPE material do not contain plasticizer, more healthy and environmentally friendly, and flexible speciality determines soft needle of infusing in infusion process 103 will not hurt blood vessel.
Disclosed above is only the specific embodiment of the application, but the application is not limited to this, any this field Technical staff can think variation, should all fall in the protection domain of the application.
