Description of reference numerals:
101-syringe, 102-push rod, 103-entry needle, 104-pushes away handle, 105-adjustable ring, 106-circular channel,107-mounting groove, 108-cutting knife, 109-button, 110-spring.
Detailed description of the invention
Below in conjunction with accompanying drawing, a detailed description of the invention of the present utility model is described in detail, but shouldUnderstand the restriction that protection domain of the present utility model is not subject to detailed description of the invention.
A kind of intravenous syringe construction schematic diagram that Fig. 1 provides for the utility model embodiment. As Fig. 1Shown in, this intravenous syringe specifically comprises: syringe 101, push rod 102, entry needle 103 and push away handle
104。
Push rod 102 is the cross body of rod, and the periphery of push rod 102 is provided with external screw thread, and push rod 102 is by outer spiral shellLine is provided with the adjustable ring 105 that can move forward and backward on push rod 102, centered by adjustable ring 105, has circleThe circulus of shape path 10 6 and be provided with the internal thread matching with push rod external screw thread, adjustable ring 105On cylindrical wall, offer about centrosymmetric two mounting grooves 107 of adjustable ring, mounting groove 107 and adjustable ring105 circular channel 106 communicates, and is provided with cutting knife 108 in mounting groove 107, and one end of cutting knife 108 isThe cutoff edge that points to push rod 102, the other end of cutting knife 108 is connected with button 109, on button 109, arrangesThere is spring 110.
In the utility model embodiment, mounting groove 107 is convex groove, comprises large mouthful of groove and osculum groove,The circular channel 106 1 side settings of osculum groove wherein deflection adjustable ring 105, and with the circle of adjustable ring 105Shape path 10 6 communicates, and the bottom of large mouthful groove is wherein connected with spring 110, spring 110 other ends and pressingButton 109 connects, and in the time pressing the button 109 operation, spring 110 is extruded, and cutting knife 108 is with button109 motions are advanced to push rod 102 directions, thereby can cutting by ejector pin 102, can between large mouthful groove and osculum grooveForm the position limiting structure to button 109.
The intravenous syringe of the utility model embodiment in use, because the periphery of push rod 102 is provided withExternal screw thread, and adjustable ring 105 has internal thread, therefore adjustable ring 105 can move forward and backward on push rod 102,When intravenous injection, turn adjustable ring 105 to precalculated position with hand, adjustable ring when predetermined amount is arrived in intravenous injection105 can be blocked by syringe 101, thereby can the amount of pushing through, and reaches the object of controlling injection volume. InjectingBi Hou, can be by pressing two buttons 109 on adjustable ring 105, and in conjunction with rotation operation, by push rod 102Damage and cut off, thereby can avoid reusing of syringe.
The intravenous syringe that the utility model embodiment provides, simple in structure, easy to use, by establishingThe adjustable ring of putting not only can facilitate the control to injection volume, by utilizing this in the time using syringeAdjustable ring damages syringe fast, prevents from reusing.
Disclosed is above only several specific embodiment of the present utility model, still, and the utility model embodimentNot limited thereto, the changes that any person skilled in the art can think of all should fall into guarantor of the present utility modelProtect scope.
