Description
Technical field
The present invention relates to technical field of medical equipment, specially a kind of continuous injection medication device.
Background technology
At present in clinical position, intravenous injection drug is extremely common administering mode because its can rapid-onset, and
Can be to avoid first pass effect, but clinically intravenous injection drug usually to drug concentration and is injected speed and is required, for example, quiet
Arteries and veins injects frusemide and usually injects stoste, and the needs such as intravenous injection contrast agent strictly calculate administration concentration, and bolus dose often has
It is strict with, injecting rear delivery tube road often has remnants, and current Normal practice is washing pipe after injecting drug, that is, after having pushed away drug
It replaces syringe or is drawn again using former syringe and inject a physiological saline or glucose again, thus cause clinical position
It complicates, not only increases the work load of nursing staff, also increase the risk of nosocomial infection, particularly with using remaining needle
Patient, due to the presence of remaining needle pipeline, for drug by that a part of liquid will necessarily be made to be trapped in pipeline after injecting, it is fixed to cause
Amount is inaccurate, and we have proposed a kind of devices that can continuously inject drug thus.
Invention content
The purpose of the present invention is to provide a kind of continuous injection medication devices, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the present invention provides the following technical solutions：A kind of continuous injection medication device, including the first needle

The medicinal metering of stringent control injection and inject speed, the present apparatus due to rubber ring 15 presence thus the first cavity 2 can not
It can inject completely, have and remain in the first cavity 2 a little, specific submit is determined by the size of rubber ring 15, under normal circumstances
The smaller volume herein of size of rubber ring 15 can be ignored, and the size of rubber ring 15 is fixed institute for the present apparatus
It is this surplus to be counted and reaches more accurate quantitative it was determined that can be adjusted to graduation mark 30 with residual volume.
Specifically, the material of the flexible clamp piece 12 is medical grade PVC or medical grade stainless steel, prevent because of material problem
Caused by pollute.
Specifically, the flexible clamp piece 12 is spring or shrapnel, it is therefore an objective to when injecting the main ingredient in the first cavity 2,
Ball valve 13 can be jacked up to be formed with rubber ring 15 and sealed, prevent from causing confusion with the liquid in the second cavity 20, and elastic card
Part 12 will not block being connected to for connecting hole 19 and unidirectional chamber 11, and flexible clamp piece 12 as shown in Figure 4 is spring, as shown in Figure 10 elasticity
Fastener 12 or shrapnel, the flexible clamp piece 12 with said effect.
Specifically, in order to make to have injected the stability of main ingredient (such as frusemide) pipeline connection afterwards, the piston head 6 is separate
One end side wall of second syringe 4 is equipped with the first external screw thread 9, first external screw thread 9 and is located in 2 front end side wall of the first cavity
The engagement connection of the first internal thread 17, the side wall of second syringe 4 is equipped with the second external screw thread 10, second external screw thread 10
Connection is engaged with the second internal thread 18 being located on 2 rear end side wall of the first cavity, rotating clockwise the second syringe 4 makes the first outer spiral shell
Line 9 and 17 at a fully engaged, the second external screw thread 10 of the first internal thread and the second internal thread 18 are at a fully engaged, and the two engages simultaneously
Or separation, the second syringe 4 is fixed inactive in the inside of the first cavity 2 after engagement, prevents from being used to rinse in the second cavity 20
Physiological saline or glucose injection when enter back into the first cavity 2.
Specifically, the rubber ring 15 is the anchor ring of concave shaped close to one end of fore-set 16, this shape is receiving extruding
After can be inwardly extended, higher sealing effect is obtained under smaller volume.
Operation principle：In use, making the first external screw thread 9 and the second external screw thread by rotating clockwise the second syringe 4 first
10 is at a fully engaged with the first internal thread 17 and the second internal thread 18 simultaneously respectively, and fore-set 16 is by ball valve 13 to the inside of unidirectional chamber 11
It heads into, the front side wall sealing of rubber ring 15 and the first cavity 2, the first cavity 1 and the external world are obstructed at this time, the second cavity 20 and the external world
Connection pulls second piston handle 23 to be extracted to the inside of the second cavity 20 and pours into physiological saline or glucose, takes out in this case
Take it is appropriate after, rotate counterclockwise the second syringe 4 make the first external screw thread 9 and the second external screw thread 10 respectively and meanwhile with the first internal thread 17
With the second internal thread 18 be detached from, rubber ring 15 and the front side wall of the first cavity 2 separate at this time, ball valve 13 detached with fore-set 16 and by
The elastic force of flexible clamp piece 12 makes it be sealed with 15 side of rubber ring, blocks the oral area of unidirectional chamber 11, therefore the first cavity 2 and the external world
It communicates, the second cavity 20 and the external world are obstructed, pull first piston 21 fixed according to scale to the inside of the first cavity 2 in this case
Amount extracts drug, is later attached the adapter sleeve of the present apparatus 27 and remaining needle pipeline 29, medicine injection is suitable again when having injected
Hour hands rotate the second syringe 4 make the first external screw thread 9 and the second external screw thread 10 respectively and meanwhile with spiral shell in the first internal thread 17 and second
Line 18 is at a fully engaged, and fore-set 16 heads into ball valve 13 to the inside of unidirectional chamber 11, and rubber ring 15 and the front side wall of the first cavity 2 are close
Envelope, the first cavity 1 and the external world are obstructed at this time, and the second cavity 20 is in communication with the outside, in this case promotion second piston handle 23 to
Physiological saline or glucose inside 29 the second cavity of internal injection 20 of remaining needle pipeline, rush remaining needle pipeline 29
It washes, prevents the residual of main ingredient from causing injection volume inaccurate, the device is mainly applied to use remaining needle pipeline 29, Ke Yiti
Height, which is injected accuracy and is also prevented from, repeatedly replaces syringe reduction working strength, reduces medical-risk, also improves safety.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
