Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of automatic blood collecting device.
Background technology
At present, when medical worker takes a blood sample, conventionally take a blood sample with common syringe, but, by common two shortcomings of blood collection needle existence, first shortcoming is the exposed outside at syringe of the syringe needle of syringe, accidentally patient or medical worker will be stabbed, second shortcoming is after the syringe needle of syringe is penetrated to patient's blood vessel, also needing medical worker to pull back the piston rod of syringe just can be by blood inhalation syringe, can not, automatically by blood inhalation syringe, increase medical worker's workload.
Summary of the invention
Problem to be solved in the utility model is: a kind of automatic blood collecting device is provided, and this blood-taking device is simple in structure, and syringe needle is hidden in outer sleeve so can stab medical worker and patient, and can Automatic Extraction patient blood.
In order to solve the problems of the technologies described above, automatic blood collecting device of the present utility model, comprise outer sleeve, in described outer sleeve, be inserted with inner sleeve, in described inner sleeve, be provided with piston, the rear portion of described piston is fixed with piston rod, described piston rod is threaded rod, described piston rod stretches out in outside inner sleeve, the end of described piston rod is provided with a pushing hands, the center of described pushing hands is provided with female thread, described female thread and piston rod match, between described pushing hands and the rear end face of inner sleeve, be provided with coil tension spring, the front end face of described inner sleeve is provided with syringe needle, described syringe needle is connected with inner sleeve, the front end face of the outer sleeve in described syringe needle front is provided with a needle outlet.
For fear of inner sleeve under the effect of self gravitation along outer sleeve down sliding, cause syringe needle to stretch out in outside needle outlet, automatic blood collecting device of the present utility model, the inwall of described outer sleeve is provided with several hoodles, and the front end face of described inner sleeve abuts on hoodle.
For the number of the blood sampling volume in moving state and the inner sleeve of Real Time Observation inner sleeve, automatic blood collecting device of the present utility model, described inner sleeve, outer sleeve are made by transparent plastic.
The beneficial effect that this utility model is obtained is: (1) is simple in structure, (2) at ordinary times time, the syringe needle on inner sleeve front end face hide with outer sleeve in, thereby can not stab because of maloperation medical worker or patient, (3) when blood sampling, press down pushing hands, under the pressure of pushing hands, piston rod moves down and drives piston to move to the below of inner sleeve, simultaneous retractable spring is also compressed, under the pressure of coil tension spring, inner sleeve moves down, inner sleeve is in the process moving down, hoodle is pressed in the inwall of outer sleeve, inner sleeve continues to move down together with syringe needle, in the time that inner sleeve is displaced downwardly to the below of outer sleeve, syringe needle just stretches out from needle outlet, medical worker just can insert syringe needle in patient's blood vessel like this, after insertion, medical worker unclamps pushing hands, pushing hands can drive on piston rod and piston and move under the effect of the resilience force of coil tension spring, piston will suck patient's blood in inner sleeve in upper process of moving, after coil tension spring resets completely, whole blood collection procedure has just completed, wherein, piston upper move blood sampling in, to rely on the resilience force of coil tension spring to complete, do not need medical worker to pull pushing hands and piston rod, thereby reduce medical worker's workload, (4) pushing hands is provided with female thread, piston rod is threaded rod, female thread and threaded rod match, thereby by adjusting the position of pushing hands on piston rod, namely regulate the length of coil tension spring, can be adjusted at when blood sampling piston on move distance, thereby realize the adjustment to blood sampling volume, very convenient, (5) inwall of outer sleeve is provided with several hoodles, and the front end face of inner sleeve abuts on hoodle, thus can avoid inner sleeve under the effect of self gravitation along outer sleeve down sliding, cause syringe needle to stretch out in outside needle outlet, (6) inner sleeve, outer sleeve are made by transparent plastic, thus can Real Time Observation blood sampling volume in moving state and the inner sleeve of inner sleeve number.

Detailed description of the invention
As shown in Figure 1, automatic blood collecting device of the present utility model, comprise outer sleeve 4, in described outer sleeve 4, be inserted with inner sleeve 6, in described inner sleeve 6, be provided with piston 5, the rear portion of described piston 5 is fixed with piston rod 9, described piston rod 9 is threaded rod, described piston rod 9 stretches out in outside inner sleeve 6, the end of described piston rod 9 is provided with a pushing hands 8, the center of described pushing hands 8 is provided with female thread, described female thread and piston rod 9 match, between described pushing hands 8 and the rear end face of inner sleeve 6, be provided with coil tension spring 7, the front end face of described inner sleeve 6 is provided with syringe needle 2, described syringe needle 2 is connected with inner sleeve 6, the front end face of the outer sleeve 4 in described syringe needle 2 fronts is provided with a needle outlet 1, the inwall of described outer sleeve 4 is provided with several hoodles 3, and the front end face of described inner sleeve 6 abuts on hoodle 3, described inner sleeve 6, outer sleeve 4 are made by transparent plastic.
Automatic blood collecting device of the present utility model, simple in structure, at ordinary times time, syringe needle on inner sleeve 6 front end faces 2 hide with outer sleeve 4 in, thereby can not stab because of maloperation medical worker or patient.
When blood sampling, press down pushing hands 8, under the pressure of pushing hands 8, piston rod 9 moves down and drives piston 5 to move to the below of inner sleeve 6, simultaneous retractable spring 7 is also compressed, under the pressure of coil tension spring 7, inner sleeve 6 moves down, inner sleeve 6 is in the process moving down, hoodle 3 is pressed in the inwall of outer sleeve 4, inner sleeve 6 continues to move down together with syringe needle 2, in the time that inner sleeve 6 is displaced downwardly to the below of outer sleeve 4, syringe needle 2 just stretches out from needle outlet 1, medical worker just can insert syringe needle 2 in patient's blood vessel like this, after insertion, medical worker unclamps pushing hands 8, pushing hands 8 can drive on piston rod 9 and piston 5 and move under the effect of the resilience force of coil tension spring 7, piston 5 will suck patient's blood in inner sleeve 6 in upper process of moving, after coil tension spring 7 resets completely, whole blood collection procedure has just completed, wherein, piston 5 upper move blood sampling in, to rely on the resilience force of coil tension spring 7 to complete, do not need medical worker to pull pushing hands 8 and piston rod 9, thereby reduce medical worker's workload.
Pushing hands 8 is provided with female thread, piston rod 9 is threaded rod, female thread and threaded rod match, thereby by adjusting the position of pushing hands 8 on piston rod 9, namely regulate the length of coil tension spring 7, can be adjusted at when blood sampling piston 5 on move distance, thereby realize the adjustment to blood sampling volume, very convenient.
The inwall of outer sleeve 4 is provided with several hoodles 3, and the front end face of inner sleeve 6 abuts on hoodle 3, thus can avoid inner sleeve 6 under the effect of self gravitation along outer sleeve 4 down slidings, cause syringe needle 2 to stretch out in outside needle outlet 1.
