Booster for medical syringe
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of booster for medical syringe.
Background technology
When using syringe to inject human body, especially when injected dose is large or medicinal liquid viscosity is higher, rely on user operating syringe by hand separately, the hand labor intensity of operator can be very large, and simultaneously injected speed also compares and is difficult to control.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of booster for medical syringe, and it can reduce the labor intensity of operator, increases work efficiency, and disassembly, cleaning sterilization is convenient.
For solving the problems of the technologies described above, booster for medical syringe of the present utility model, comprising: first component, second component, the 3rd parts and the 4th parts; Described first component comprises palmar hand, finger ring portion, top internal thread loose joint, top ends, the first articulated section, cut-off portion, fixed screw and spring; Described cut-off portion embeds top ends, and is connected with top ends by spring; Described second component and first component are hinged, and comprise finger face, the second articulated section, the 3rd articulated section, bayonet socket and spring leaf; Described second articulated section is hinged with the first articulated section, the 3rd articulated section respectively; Described spring leaf is arranged on below the 3rd articulated section and bayonet socket; Described 3rd parts are connected with first component, include plug boosting head, amount agent push rod and rollback portion; Described amount agent push rod passes from described cut-off portion; Described 4th parts are connected with first component, include the loose joint of syringe bayonet socket; This syringe bayonet socket loose joint is fixedly connected with the top internal thread loose joint of first component.
Described booster for medical syringe entirety is in handgun shape.
Preferably, described palmar hand meet facies palmaris adopt be applicable to palm against cambered surface.
Preferably, the finger face of meeting in described finger face adopts the cambered surface being applicable to finger hold, and can arrange the antiskid groove of gear-like further on the surface in finger face, so that hands is to the grasping of booster for medical syringe.
This utility model utilizes lever principle to design booster for medical syringe auxiliary injection, not only alleviate the labor intensity of operator, improve work efficiency, and it is sturdy and durable, disassembly, cleaning sterilization convenient (the multiple method such as available medicining liquid dipping or disinfection with high pressure steam carries out disinfection), is applicable to the syringe of multiple dosage.

Detailed description of the invention
Understand more specifically for having technology contents of the present utility model, feature and effect, now by reference to the accompanying drawings, details are as follows:
The booster for medical syringe of the present embodiment, what material adopted is 17-4 rustless steel, and overall structure is pistol shape, as shown in Figure 1, 2, includes: first component 1, second component 2, the 3rd parts 3 and the 4th parts 4.
Described first component 1 includes palmar hand 11, finger ring portion 12, top internal thread loose joint 13, top ends 14, first articulated section 15, cut-off portion 16, spring 7, fixed screw 8 and spring 9.Described palmar hand 11 meet facies palmaris adopt be suitable for palm against cambered surface.Described cut-off portion 16 embeds top ends 14, and is connected with top ends 14 by spring 7.
Described second component 2 is hinged with first component 1, includes articulated section 22, finger face 21, second, the 3rd articulated section 23, bayonet socket 24 and spring leaf 10.The finger face of meeting in described finger face 21 adopts the cambered surface being suitable for pointing hold, and the surface in finger face 21 is provided with the antiskid groove of gear-like, so that hands is to the grasping of booster for medical syringe.Described second articulated section 22 is hinged by pin 6 and the 3rd articulated section 23.Described second articulated section 22 is hinged by first articulated section 15 of pin 5 with first component 1.Described spring leaf 10 is arranged on the below of the 3rd articulated section 23 and bayonet socket 24.
Described 3rd parts 3 are connected with first component 1, include plug boosting 31, amount agent push rod 32 and rollback portion 33.Described amount agent push rod 32 passes from described cut-off portion 16.
Described 4th parts 4 are connected with first component 1, include syringe bayonet socket loose joint 41.This syringe bayonet socket loose joint 41 is fixedly connected with the top internal thread loose joint 13 of first component 1.
The using method of said syringe booster is as follows:
During use, syringe is placed in the draw-in groove of syringe bayonet socket loose joint 41, palmar hand 11 is resisted against with palm, forefinger hooks finger ring portion 12, now thumb and forefinger formed one ring-like, hold with a firm grip to palmar hand 11 direction in other finger grippings finger 21 of stopping, then bayonet socket 24 forward slip, under the active force of spring leaf 10, bayonet socket 24 is upwards in the push rod of the amount of sticking into agent simultaneously 32 mouths, band momentum agent push rod 32 marches forward, in amount agent push rod 32 advance process, plug boosting 31 withstands syringe rubber plug, continue to have an effect, when syringe rubber plug advances to injector head, complete injection.Pin cut-off portion 16 downwards with finger, simultaneously with pulling rollback portion 33 rearward to bottom, taking off syringe, booster can be resetted.
