Description
Technical field
This utility model relates to a kind of syringe, particularly a kind of hand screw type high pressure injector.
Background technology
Along with China slowly entering aging, therefore medical industry also constantly brings pressure; Medical apparatus and instruments demand increases gradually, also brings medical apparatus and instruments and constantly innovate while medical apparatus and instruments increases.Traditional syringe is comparatively simple, uses very difficult when pressure ratio is larger outside, and push rod can be made when external pressure is large simultaneously to bounce back cannot work; If the conduit that the pressure ratio of push rod release is connected with traditional syringe time larger or outlet tube easily come off; The conversion of ordinary syringe and high pressure injector can not be realized simultaneously.
For solving above-mentioned deficiency, this utility model provides a kind of hand screw type high pressure injector.
Utility model content
The purpose of this utility model is to provide a kind of hand screw type high pressure injector at this, can solve the conversion of high pressure injector and ordinary syringe, use special injection head ensure that to make in case of high pressures not coming off of conduit and outlet tube simultaneously, coordinate to prevent by threaded push rod and screw buckle and carry pressure large appearance retraction phenomenon outward; This utility model structure is simple, reasonable in design, adopts screw, very laborsaving when injecting; Be applicable to applying to tremulous pulse, vein and intralymphatic injection, suppository is injected, blood vessel and the expansion of non-vascular tube chamber angioplasty balloon etc.; And different size can be made as and be used in various aspects.
This utility model is achieved in that a kind of hand screw type high pressure injector of structure comprises portion of the handle, push rod and cylindrical shell; It is characterized in that portion of the handle comprises upper cover, lower cover, screw buckle and spring, screw buckle is arranged between upper cover and lower cover; Push rod coordinates with cylindrical shell.
According to hand screw type high pressure injector described in the utility model, screw buckle is provided with female thread, and back is provided with projection, and projection is through being located at the hole covered; The control of user double thread button is facilitated by the projection arranged.
According to hand screw type high pressure injector described in the utility model, the female thread on screw buckle matches with the external screw thread be located on push rod; Achieve rotary motion by the cooperation of internal and external threads, while rotation, promoted the reach of push rod, thus the liquid promoted in cylindrical shell moves ahead.
According to hand screw type high pressure injector described in the utility model, lower cover and cylindrical shell are an entirety, be provided with four springs, form springlock gear control switch by spring with coordinating of screw buckle between lower cover and screw buckle; Its role is to: use springlock gear control switch can switch hand screw type high pressure injector high-pressure injection and normal injection two states.
According to hand screw type high pressure injector described in the utility model, putter design is hollow axle, is provided with handle at tail end, and front end is provided with the plug installation position of plug; Plug front end is taper and is provided with four symmetrical convex keys; Be set to hollow axle and save material, plug be set to taper and design four convex keys add plug with push away the contact area of liquid.
This utility model is matched with the female thread of screw buckle by threaded push rod, prevents outer to carry that pressure is excessive makes pusher retracted, is injected by screw simultaneously, very light when making to inject; Be provided with spring between lower cover and screw buckle, constitute springlock gear control switch; Achieve hand screw type high pressure injector by springlock and there are two control gears, facilitate the conversion of ordinary syringe and high pressure injector.
Hand screw type major parameter has:
Syringe capacity > 20ml
Injection pressure > 35atm
Injection thrust < 3kg
This utility model tool has the following advantages:
Advantage one: adopting spiral handspike, manually simply, is screw when injecting, very laborsaving.
Advantage two: when switching to high-pressure injection, pressure is 6 to 10 times of ordinary syringe, makes injection more smooth.
Advantage three: pressure and flow rate can control, and adopt spiral handspike push rod only to be advanced, can not retreat, therefore continue like that arduously to exert oneself with strength without the need to ordinary syringe.
Advantage four: hand screw type high pressure injector nipple adopts LUER to revolve latching connector, directly mates with tube for transfusion or tail end of conduit and links, therefore can ensure during high-pressure injection that tube for transfusion or conduit can not come off.
Advantage five: hand screw type high pressure injector is provided with springlock gear and controls, and can realize the conversion of high pressure injector and ordinary syringe.
