SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a syringe for department of anesthesia of steerable dose, the distance of piston propelling movement when this syringe passes through the cooperation control narcotic injection of dog and needle tubing upper end to carry out better control to narcotic injection volume.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a syringe for department of anesthesia of steerable dose, includes the needle tubing, syringe needle is installed to the bottom of needle tubing, the inner chamber of needle tubing is provided with pushing mechanism, the last scale mark that is provided with of pushing mechanism, pushing mechanism's the outside is provided with adjustment mechanism, adjustment mechanism includes threaded connection in the thread bush on screw rod surface, the lateral wall top symmetry of thread bush link firmly two with needle tubing top complex dog, the lateral wall upper end symmetry of needle tubing runs through and is provided with two gag lever posts rather than threaded connection, the medial extremity of gag lever post is provided with bulb shape structure, the vertical medial extremity sliding fit's with the gag lever post spout of seting up on the thread bush.
Preferably, the pushing mechanism comprises a threaded rod movably connected to the inner cavity of the needle tube, the bottom of the threaded rod is rotatably connected with a piston through a bearing, and the top of the threaded rod penetrates through the top of the needle tube and is fixedly connected with a push block.
Preferably, the graduation marks are arranged on the surface of the threaded rod.
Preferably, a space is respectively reserved between the upper end and the lower end of the sliding groove and the upper end and the lower end of the threaded sleeve.
Compared with the prior art, the beneficial effects of the utility model are as follows: in this syringe for department of anesthesia of steerable dose, the adjustment of dog position is realized through the cooperation of thread bush and threaded rod and the cooperation of gag lever post and spout to the distance of piston propelling movement when controlling the narcotic injection through the cooperation of dog and needle tubing upper end, thereby carries out better control to narcotic injection volume.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a syringe for department of anesthesia of steerable dose, includes needle tubing 1, syringe needle 2 is installed to the bottom of needle tubing 1, the inner chamber of needle tubing 1 is provided with pushing mechanism 3, be provided with scale mark 8 on the pushing mechanism 3, the outside of pushing mechanism 3 is provided with adjustment mechanism 4, adjustment mechanism 4 includes threaded connection in the thread bush 41 on threaded rod 31 surface, the lateral wall top symmetry of thread bush 41 links firmly two with 1 top complex dog 42 of needle tubing, the lateral wall upper end symmetry of needle tubing 1 runs through be provided with two gag lever post 51 rather than threaded connection, the medial extremity of gag lever post 51 is provided with bulb shape structure, along vertical seting up with gag lever post 51's medial extremity sliding fit's spout 52 on the thread bush 41. And a space is reserved between the upper end and the lower end of the sliding groove 52 and the upper end and the lower end of the threaded sleeve 41 respectively. Through the cooperation of gag lever post 51 and spout 52, when thread bush 41 reciprocated, gag lever post 51 and spout 52 relative slip, and then played limiting displacement to thread bush 41, avoided thread bush 41 to follow threaded rod 31 synchronous revolution. When the whole injector is assembled, the limiting rod 51 is rotated to enable the limiting rod 51 to exit from the inner cavity of the needle tube 1, and after the threaded rod 31, the piston 32 and the threaded sleeve 41 enter the needle tube 1, the limiting rod 51 is screwed down until the ball end of the limiting rod 51 is contacted with the sliding groove 52.
The pushing mechanism 3 comprises a threaded rod 31 movably connected to the inner cavity of the needle tube 1, and the scale marks 8 are arranged on the surface of the threaded rod 31. The bottom of the threaded rod 31 is rotatably connected with a piston 32 through a bearing, and the top of the threaded rod 31 penetrates through the top of the needle tube 1 and is fixedly connected with a push block 33.
The working principle is as follows: firstly, the injection dosage of the anesthetic is determined according to the specific condition of a patient, one hand holds the needle tube 1, the other hand rotates the push block 33, the push block 33 drives the threaded rod 31 to rotate, the threaded rod 31 drives the threaded sleeve 41 to move up and down on the surface of the threaded rod 31 through threads on the surface under the limiting action of the limiting rod 51 and the sliding groove 52, so that the position of the stop block 42 is adjusted, the push block 33 is pushed downwards according to the scale marks 8 on the surface of the threaded rod 31 until the proper position is adjusted, the push block 33 drives the threaded rod 31, the threaded sleeve 41, the stop block 42 and the piston 32 to move downwards until the stop block 42 moves downwards to be in contact with the needle tube 1, and then the stop block cannot move downwards any more, and the injection of the anesthetic with the. The pushing distance of the piston 32 during the injection of the anesthetic can be controlled by adjusting the position of the stopper 42, so that the injection amount of the anesthetic can be better controlled.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
