A kind of children's safety hemostixTechnical field
The present invention relates to a kind of hemostix, especially a kind of children's safety hemostix.
Background technique
In clinical position, children make pediatric nurses blood drawing become one big pain when fearing and taking a blood sample of medical environmentProblem.The problem of encountering when clinical nurse venous blood collection is as follows: firstly, crying and screaming does not allow nurses collecting blood whole body involuntary movement, shieldScholar has no chance inserting needle at all；Secondly, blood taking needle comes into blood vessel because fearing and pain, patient, which does not stop to juggle things, to cause to adoptBlood needle abjection blood vessel causes secondary blood sampling.But most of infant can smoothly complete blood sampling under the auxiliary of toy for children, simultaneouslyInfant is greatly reduced to the fear of blood sampling, increases infant and the degree of belief of nurse, nurse also can be easily, giocoso infantCarry out venipuncture；In addition since the puncture needle of operation test tube often wears the protective glue outside puncture of test tube needle in blood collection procedurePierce it is bad, blood leak out leakage on test tube even flows in nurse's hand；Blood collecting puncture needle head often exposes after blood sampling, exposureHour hands headband is bled liquid, while while exposing often accidentally will cause the generation for puncturing wound.
Summary of the invention
It is described the invention discloses a kind of children's safety hemostix, including syringe needle and needle stand to solve the above existing problemSyringe needle is connected with the needle stand；The needle stand is connected with needle stand cylinder；The needle stand and the needle stand cylinder are fixed in piston cylinder；InstituteIt states and is equipped with piston detent inside piston cylinder, outside is equipped with piston cylinder detent；Have between the piston cylinder detent and the needle stand cylinderSyringe needle drag hook；The syringe needle drag hook is connected with plastic cement pipeline；The plastic cement pipeline is equipped with handle；The plastic cement pipe end isHose；There is hose clamp on the hose；The hose is connected through a screw thread mouth and is connected with Bruce head；The hose end is to changeGood puncture needle is covered with blood sampling sleeve outside the improvement puncture needle；There is Needle outlet in the hemostix front end, and there is hose in rear endHole；
The hemostix further includes catheter block lower bottom base and catheter block upper bed-plate, the catheter block lower bottom base and the conduitSeat upper bed-plate is detachable or non-removable connection；Have under the fixed road of conduit on the catheter block lower bottom base；On the catheter blockThere is on the fixed road of conduit and fixes upper track groove on pedestal；
The hemostix further includes cartoon component, and the cartoon component is fixed on the hemostix；
The cartoon component is cartoon soft-slab, and the cartoon soft-slab is pasted on the catheter block upper bed-plate.
Preferably, the improvement puncture needle is equipped with puncture of test tube needle protective case.
Preferably, the catheter block lower bottom base and the catheter block upper bed-plate pass through the catheter block of the catheter block lower bottom baseCatheter block upper bed-plate protrusion fastening on lower bottom base groove and the catheter block upper bed-plate is attached and fixes.
Preferably, the cartoon component is cartoon liner, and the cartoon liner is fixed on the catheter block upper bed-plate and instituteIt states between catheter block lower bottom base；Cartoon set is cased with outside the cartoon liner.
Preferably, the cartoon liner is provided with catheter block, and the catheter block is equipped with square groove；Cartoon liner tail portionThere is connector opening.
Preferably, the cartoon liner further includes sealing groove.
Preferably, the cartoon liner further includes sealing detent.
Preferably, the needle stand cylinder is equipped with detent close to one end of the syringe needle drag hook.
Preferably, the catheter block lower bottom base is in ramp type, and flank angle is 10 degree.
Preferably, the cartoon component and the hemostix, which use, snaps connection mode.
The utility model has the advantages that the configuration of the present invention is simple, scientific and reasonable；Cartoon component can attract attention children, so that shieldScholar has an opportunity inserting needle, and can smoothly complete blood sampling, while greatly reducing infant to the fear of blood sampling；Blood sampling is worn after blood samplingPricker head will not expose, and not will cause the blood outflow adopted and the generation for puncturing wound.
