Abstract

The utility model relates to a medical device, in particular to an injector. A spring is hinged between a moving handle and a fixed handle, the upper end of the moving handle is provided with a pawl, the upper end of the fixed handle is provided with an injector seat which can be used to fix the common injector and a push rod sleeved on the injector seat, the push rod is provided with a locking component coordinating with the pawl. When injecting, the injector can be operated by single hand, and is convenient and practical, the hinged handle change the forcing direction and the size of the moment, when used, the injector is much more labor saving.

Description

The cicatrix syringe

This utility model relates to a kind of medical apparatus and instruments, especially a kind of syringe.

Common syringe is at an end of the container of tubular injection needle to be installed, and the other end is installed piston, and direct push-and-pull piston is gone out injecting liquid drug during use.But because the scar tissue structure is tight, need very big strength could promote piston during to the scar tissue injection for curing, numerous medical personnel press for a kind of convenient and practical cicatrix syringe that can carry out the scar tissue injection for curing.

The purpose of this utility model provides a kind of simple in structure, labour-saving cicatrix syringe.

For achieving the above object, this utility model adopts following technical scheme:

Cicatrix syringe described in the utility model is at hinged fixed handle and decide to have between the handle spring, the upper end of fixed handle has ratchet, the upper end of deciding handle has the fixedly syringe tray and the pushing ram that is sleeved on the syringe tray of ordinary syringe, has the clamping part with click-fit on the pushing ram.

After adopting technique scheme, medical personnel hold handle and just can inject as long as ordinary syringe is installed on the syringe tray, can one-handed performance during injection, convenient and practical, hinged handle has changed the stressed direction and the size of moment, and is very laborsaving during use.

Further specify this utility model below in conjunction with drawings and Examples:

Accompanying drawing is the structural representation of an embodiment of the present utility model.

As shown in drawings, cicatrix syringe described in the utility model is at hinged fixed handle 10 and decide to be provided with between the handle 9 spring 7, the upper end of fixed handle 10 has ratchet 4, the upper end of deciding handle 9 has the fixedly syringe tray 2 and the pushing ram 3 that is sleeved on the syringe tray 2 of ordinary syringe, have the clamping part 11 that cooperates with ratchet 4 on the pushing ram 3, this clamping part 11 is exactly the some boss that are evenly distributed on the pushing ram 3.Syringe tray 2 comprises a slightly base plate of groove, base plate have the clip that can block the ordinary syringe front end foremost, the centre of base plate has a clip that can block the ordinary syringe shell, base plate have a sleeve pipe backmost, pushing ram 3 just is installed in this sleeve pipe.

During use, ordinary syringe is installed on the syringe tray 2, hold and decide handle 9 and fixed handle 10, ratchet 4 on the fixed handle 10 blocks clamping part 11, firmly handle just can promote pushing ram 3 and moves forward, thereby the piston of pushing syringe moves ahead, during release handle, handle is return under the effect of spring 7, and ratchet 4 separates with clamping part 11 and retreats after certain distance once more and clamping part 11 engagements.

Claims

1, cicatrix syringe, it is characterized in that: hinged fixed handle (10) and decide to have between the handle (9) spring (7), the upper end of fixed handle (10) has ratchet (4), the upper end of deciding handle (9) has the fixing syringe tray of ordinary syringe (2) and is sleeved on pushing ram (3) on the syringe tray (2), has the clamping part (11) that cooperates with ratchet (4) on the pushing ram (3).

2, cicatrix syringe according to claim 1, it is characterized in that: syringe tray (2) comprises a slightly base plate of groove, base plate have the clip that can block the ordinary syringe front end foremost, the centre of base plate has a clip that can block the ordinary syringe shell, base plate have a sleeve pipe backmost, pushing ram 3 just is installed in this sleeve pipe.
