Description
Technical field
The utility model relates to a kind of medical apparatus and instruments, be the type self-destroyed high pressure syringe pump syringe of disposable use.
Background technology
Utilizing the drive driving device to carry out vascular perfusion and radiography is that clinical radiation gets involved important treatment of subject and diagnostic means.This technology of irradiation image technology has been widely used for fields such as radiology department's image radiography, and the domestic hospital's overwhelming majority that has image documentation equipment has at present been carried out the work of this respect.
Disposable use high pressure syringe pump syringe is to be widely used in the medical apparatus that is used for the work of clinical vein high pressure radiography in the medical treatment.
Clinical step of carrying out vein high pressure radiography is generally: at first fixedly the high pressure syringe pump syringe is to special-purpose syringe pump draw-in groove, by medicine absorbing tube contrast agent in the vial is sucked in the syringe and prolongs pipe with high pressure simultaneously and link to each other, finish aerofluxus then, be connected work with venipuncture needle.Import injection capacity, pressure, speed command by control panel to special-purpose syringe pump at compartment by the operator.After finishing using, its structural integrity is intact, still has reusable probability, and reality can't be guaranteed disposable use in clinical practice.
Summary of the invention
The purpose of this utility model is at above-mentioned weak point, provide a kind of disposable use type self-destroyed high pressure syringe pump syringe, can self-destruction after finishing using, can not self-destruction after having overcome existing disposable use high pressure syringe pump syringe and using, and reusable and defective cross infection.
The type self-destroyed high pressure syringe pump syringe of disposable use takes following mode to realize: the type self-destroyed high pressure syringe pump syringe cylinder structure of disposable use comprises injection tube, plug deck, supporter, rubber piston, supporter is sleeved on the plug deck, rubber piston is sleeved on the supporter, form one formation piston component and be contained in the injection tube, can in the injection tube, promote.Plug deck bottom is provided with two Connection Card posts, and each Connection Card post is divided into upper and lower two-part structure, and top is brace or joint pin, and the bottom is for connecting bayonet socket, and upper and lower two parts connect adult.Joint pin can be provided with two joint pins with certain angle of inclination and connect into an overall structure.The joint pin tilt angle alpha is 45 °～65 °.
When the type self-destroyed high pressure syringe pump syringe of disposable use uses, the high pressure syringe pump syringe is fixed in the special-purpose syringe pump draw-in groove, by medicine absorbing tube contrast agent in the vial is sucked in the injection tube and prolongs pipe with high pressure simultaneously and link to each other, finish aerofluxus then, be connected work with venipuncture needle.Behind special-purpose syringe pump input injection capacity, pressure, speed command, the high pressure syringe pump syringe begins to inject contrast agent to the operator under high pressure conditions by control panel.Because its propelling pressure is bigger, cause the brace of plug deck bottom or joint pin pressurized and rupture, piston component and special-purpose syringe pump draw-in groove are broken away from, when having injected contrast agent, when special-purpose syringe pump draw-in groove pushes back, piston component is left in the high pressure syringe pump syringe, loses reusable function, thereby realizes the disposable use and the self-destruction of true meaning.
The type self-destroyed high pressure syringe pump barrel design of disposable use is reasonable, simple in structure, can prevent that secondary from using, and avoids cross infection, is convenient to clinical use, can with the use that is complementary of existing special-purpose syringe pump draw-in groove.

The specific embodiment
With reference to accompanying drawing 1～5, the type self-destroyed high pressure syringe pump syringe cylinder structure of disposable use comprises injection tube 1, plug deck 4, supporter 7, rubber piston 3, supporter 7 is sleeved on the plug deck 4, rubber piston 3 is sleeved on the supporter 7, form one formation piston component and be contained in the injection tube 1, can in injection tube 1, promote.Plug deck 4 bottoms are provided with two Connection Card posts 5, and each Connection Card post is divided into upper and lower two-part structure, and top is brace or joint pin, and the bottom is for connecting bayonet socket, and upper and lower two parts link into an integrated entity.Joint pin can be provided with two joint pins with certain angle of inclination and connect into an overall structure.The joint pin tilt angle alpha is 45 °～65 °.
Injection tube 2 tops are provided with medicine-pouring pipe connector 1, and medicine-pouring pipe connector 1 is provided with connecting thread.Injection tube 2 bottoms are provided with the injection tube and connect bayonet socket 6, are convenient to during use be connected with special-purpose syringe pump.
With reference to accompanying drawing 2,3, the piston component embodiment 1 of the type self-destroyed high pressure syringe pump syringe of disposable use, plug deck 4 bottoms of piston component are provided with two Connection Card posts 5, are used for high pressure syringe pump syringe clamping in special-purpose syringe pump draw-in groove.Each Connection Card post 5 is divided into upper and lower two-part structure, and top is joint pin 5-1, and the bottom is for connecting bayonet socket 5-2, and upper and lower two parts link into an integrated entity.Joint pin 5-1 can be provided with two joint pins with certain angle of inclination and connect into an overall structure.The joint pin tilt angle alpha is 45 °～65 °.Propelling pressure is bigger during use, causes the joint pin pressurized of plug deck bottom and ruptures, and makes the disengaging of piston component and special-purpose syringe pump draw-in groove.When having injected contrast agent, when special-purpose syringe pump draw-in groove pushed back, piston component was left in the high pressure syringe pump syringe, promptly in the injection tube 2, lost reusable function, thereby realized the disposable use and the self-destruction of true meaning.
With reference to accompanying drawing 4,5, the piston component embodiment 2 of the type self-destroyed high pressure syringe pump syringe of disposable use, plug deck 4 bottoms of piston component are provided with two Connection Card posts 5, are used for high pressure syringe pump syringe clamping in special-purpose syringe pump draw-in groove.Each Connection Card post 5 is divided into upper and lower two-part structure, and top is brace 5-3, and the bottom is for connecting bayonet socket 5-4, and upper and lower two parts link into an integrated entity.Propelling pressure is bigger during use, causes the brace pressurized of plug deck bottom and ruptures, and makes the disengaging of piston component and special-purpose syringe pump draw-in groove.When having injected contrast agent, when special-purpose syringe pump draw-in groove pushed back, piston component was left in the high pressure syringe pump syringe, promptly in the injection tube 2, lost reusable function, thereby realized the disposable use and the self-destruction of true meaning.
