Abstract
The utility model discloses a blood sampling device capable of being directly inserted in a test tube. The utility model is composed of an air pumping cylinder 1, a piston 2, a piston rod 3, a puncture needle 4, a needle seat 5 and a test tube 6, wherein, the front end of the air pumping cylinder 1 is provided with a joint for external threads 7, and the opening part of the needle seat 5 is provided with internal threads and is connected with the joint for external threads 7 of the air pumping cylinder 1. The outer wall of the needle seat 5 is connected and fixed to the test tube 6 through a test tube plug 9 by a connecting tube 8. The tail end of the puncture needle 4 is inserted in the test tube plug 9, and the puncture needle is extended into the test tube 6. An air pumping tube 12 is connected to the outside of an air pumping hole 11 on the air pumping cylinder 1. The air pumping tube 12 is inserted inside the test tube 6. Because of an integral body of the needle and the test tube, the blood sampling device capable of being directly inserted in a test tube can be used for directly sampling blood into the test tube. The whole process is hermetically operated. The operation procedure can be decreased, the labor intensity can be lightened, and the occurrence of hemolysis and aerosol phenomena can be prevented.
Description
Technical field
This utility model relates to the improvement of blood-taking device, the especially a kind of hemostix that can directly blood be adopted into test tube.
Background technology
Traditional blood-sampling method is: use earlier blood collection needle, the puncture needle that is about to syringe thrusts human vein, spurs piston rod again, blood is sucked in the syringe, and then puncture needle put into the test tube mouth, and promote piston rod, blood is entered in vitro, again with test tube mouth plug seal, the shortcoming of this blood-sampling method is: 1, blood taking needle separates with test tube, must " take out " " notes " two actions, and operating procedure is many, inconvenience, labor intensity is big; 2, test tube uncork, invisible spectro blood air-capacitor glue can occur and form, and cause gaseous contamination, and then can injure the staff; 3, adopt into the blood in the syringe, when in vitro injecting, blood produces bump, easily causes haemolysis.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of test tube and puncture needle one are provided, can directly blood be adopted into invisible spectro hemostix, thereby reduced operating procedure, alleviate staff's labor intensity, also prevent the appearance of haemolysis and air-capacitor glue simultaneously, avoided polluting and infecting.
For solving above technical problem, the technical scheme that this utility model adopted is: this can directly adopt the hemostix into test tube, by pump bowl, piston, piston rod, puncture needle, needle stand, test tube constitutes, front end at pump bowl is established male connection, the oral area of needle stand is established female thread, and be rotatably connected with the male connection of pump bowl, make pump bowl and needle stand, puncture needle is connected to an integral body, on the outer wall of needle stand, establish the connection tube that connects test tube, connection tube is connected and fixed by test tube plug and test tube, crooked 90 degree of the tail end of puncture needle insert the test tube plug, and extend in vitro, establish passage on the pump bowl front bulkhead, on the aft bulkhead of pump bowl, establish aspirating hole, the external exhaust tube of aspirating hole, exhaust tube, and insert the test tube plug and in vitro are communicated with to the test tube plug along the pump bowl outer wall.When using this utility model, after puncture needle thrusts vein, as long as promote piston rod, piston forward is moved, exhaust tube is just in vitro bleeding, make in vitro to form negative pressure, the vein hemafecia is directly adopted in vitro, during blood sampling by crooked needle tubing, be inclined upwardly at the bottom of making test tube, prevent that invisible spectro blood from entering exhaust tube, by the reverse scale observation blood sampling volume of test tube, adopt enough amounts after, the test tube plug is pulled up together with test tube, extract blood taking needle and exhaust tube and promptly take a blood sample and finish, puncture needle, needle stand, pump bowl are disposable application, protect from infection.This utility model is also implemented by following measure: the test tube plug is a rubber stopper, and round platform is all established in both sides, and the round platform of a side is filled in the mouth of connection tube, and the round platform of opposite side is filled in the mouth of test tube, thereby test tube and connection tube are connected and fixed; The curved end head of puncture needle also is a syringe needle, and in order to inserting the test tube plug, its syringe needle length is passed the test tube plug with the degree of depth of inserting test tube and is advisable; Exhaust tube inserts an invisible spectro end and also is needle tubing, and it inserts the invisible spectro degree of depth and is advisable for the bottom of inserting test tube; Be carved with forward scale and reverse scale on the wall of test tube, oppositely graduated " O " line position is filled on the depth line position of test tube at the test tube plug, so that the observation blood sampling volume.
The beneficial effects of the utility model are: pin and test tube one, and the blood of extraction directly enters test tube, has reduced operating procedure, has alleviated labor intensity, has prevented to produce hemolytic phenomenon because of bump; Because blood collection procedure is totally enclosed, has avoided the generation of air-capacitor glue phenomenon; Owing to during blood sampling, be to promote piston rod, meet people's custom, easily operation.
