Fig. 2 is a schematic structural view of an injector according to a second embodiment of the present invention.
Detailed Description
The present invention will now be described in more detail with reference to the drawings, in which preferred embodiments of the invention are shown, it being understood that one skilled in the art could modify the invention herein described while still achieving the beneficial effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
A first embodiment of the present invention provides a syringe, see fig. 1, which comprises: the device comprises a cylindrical barrel 1, wherein a needle joint 2 is arranged at one end of the barrel, a first boring part 3 close to the needle joint 2 and a second boring part 4 close to the tail part of the barrel are arranged in the barrel, and the first boring part 3 and the second boring part 4 are adjacently arranged; a plunger 5 disposed in the first bore portion and movable along an inner wall of the first bore portion, and made of an elastic body; the plunger rod 6 is arranged in the barrel, one end of the plunger rod is connected with the plunger 5, the other end of the plunger rod is provided with a pressing head 7, and the plunger rod with a cross-shaped section is symmetrically provided with notches and/or bulges 9 in an array along at least one part of the length of the plunger rod; an insert 8 provided in the second bore portion and provided with a cross-shaped opening for passage of the plunger rod, the two co-linear channels being provided with fingers which in use engage an array of recesses and/or projections on the plunger rod. The aforementioned structure is prior art, and reference is made to the patent technology mentioned in the background.
Referring to fig. 1, the holding ear part arranged on the barrel is in a straight shape, the free end of the holding ear part in the straight shape is in a circular arc shape, the free end of the holding ear part is provided with a foldable holding part 10 through a hinge 11, and the foldable holding part is a plate-shaped body. The hinge is arranged on the lower surface (close to the needle joint) of the position of the hand-held ear part adjacent to the foldable hand-held part.
It can be seen from the above that, the length of the hand-held ear part of the needle cylinder can be lengthened after the foldable hand-held part is turned up, so that the syringe is convenient for operators with large hands to use, the foldable hand-held part can only move towards the direction away from the needle joint due to the hinge arranged on the lower surface of the hand-held ear part, and the turned-up foldable hand-held part can not be freely turned back to the folded state due to the stress state of the hand.
As can be seen from fig. 1, the length of the foldable handheld portion is smaller than that of the handheld ear portion, so that the foldable handheld portion can be hidden under the lower surface of the handheld ear portion when the foldable handheld portion is in a folded state, and the overlong foldable handheld portion cannot be completely folded under the lower surface of the handheld ear portion.
The second embodiment of the present invention provides a syringe, which is different from the first embodiment in that, referring to fig. 2, a T-shaped connector 12 is provided between the foldable handheld portion and the handheld ear portion, and an insertion groove/hole matched with the T-shaped connector is provided between the foldable handheld portion and the handheld ear portion.
Thus, the state of the folded handheld part can be more stable and reliable.
The improvement lies in that the hole wall that is provided with the spliced eye that cooperates with T type plug connector between collapsible handheld portion and the handheld ear is provided with the magnet cover, and T type plug connector is the metalwork to can let the T type plug connector that just lies in the spliced eye adsorb just to lie in downtheholely, improve the stability of T type plug connector installation.
Certainly, the rubber sleeve (the open end of the rubber sleeve is close to the surface of the cylinder body) matched with the appearance of the handheld ear part which is extended after being turned up is sleeved on the handheld ear part, so that the handheld comfort level of an operator is improved.
To sum up, the utility model provides an injector is owing to be provided with the semicircular bulge that the array arranged on the plunger rod (have the clearance between the adjacent semicircular bulge, the cross-section has this semicircular bulge structure for criss-cross plunger rod symmetrical arrangement), and be provided with in two cell bodies of symmetry in the cross of insert through the opening with the meshing of semicircular bulge finger-shaped (can with the protruding slice of semicircular bulge meshing), thereby let semicircular bulge and finger-shaped cooperation and send the clatter at the in-process of plunger rod propelling movement injection, just can let finger-shaped cooperation semicircular bulge to send the clatter because the bellied adjacent distance of semicircular bulge can decide the propelling movement certain distance, thereby indicate corresponding injection dosage (this is decided by the bellied interval of adjacent semicircle, current technologies such as 2014800057722 can be referred to the principle).
The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
