Description
Technical field
This utility model relates to medical instruments field, especially a kind of Novel gynecological anesthetic syringe.
Background technology
At present, at department of obstetrics and gynecology clinically, when patient is carried out to vagina, cervix uteri, intrauterine surgical, conventionally need to carry out preoperative anesthesia, the apparatus that anesthesia is used is at present mostly common vacuum injector, this syringe is shorter, need to connect after stereoplasm tube and probe into vagina depths perfusion anesthetis, and operation is trouble very, waste time and energy, execute numb scope wayward, anesthetis diffusion is inhomogeneous, has increased greatly medical worker's work difficulty.
Utility model content
The purpose of this utility model is to provide a kind of Novel gynecological anesthetic syringe in order to overcome above-mentioned technical disadvantages, at the front end of stereoplasm tube, the spray medicine head that is provided with multiple medicine outlet holes is installed, and reaches and evenly sprays narcotic object.
The technical scheme that this utility model technical solution problem adopts is: a kind of Novel gynecological anesthetic syringe, comprise negative pressure cylinder, long duct and spray medicine head, in described negative pressure cylinder, be provided with piston, outer wall is provided with graduation mark, negative pressure cylinder front end is fixedly connected with long duct, and described spray medicine head end is provided with nut, and the outer wall of described long duct leading section is provided with the screw thread with the suitable cover of nut inner wall, spray medicine head and long duct spin fixing by screw thread, nut, described spray medicine head is provided with multiple medicine outlet holes.
Described long duct is plastic conduit, and the length of long duct is 10～14cm.
Medicine outlet hole on described spray medicine head is evenly arranged, and aperture is 1.5～3.0mm.
The beneficial effect that this utility model has is: this utility model is simple in structure, and flexible operation is executed numb position and easily controlled, and anesthetis consumption is accurate, sprinkling is even, has guaranteed anaesthetic effect, has reduced medical worker's work difficulty.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1, this utility model is described below.
As shown in Figure 1, this utility model comprises negative pressure cylinder 1, long duct 2 and spray medicine head 3, in described negative pressure cylinder 1, is provided with piston 6, and outer wall is provided with graduation mark 7, and negative pressure cylinder 1 front end is fixedly connected with long duct 2, and described spray medicine head 3 ends are provided with nut 4,
The outer wall of described long duct 2 leading sections is provided with the screw thread 5 with the suitable cover of nut 4 inwall, and spray medicine head 3 and long duct 2 spin fixing, and described spray medicine head 3 is provided with multiple medicine outlet holes 8; Described long duct 2 is plastic conduit, and the length of long duct 2 is 10～14cm; Medicine outlet hole 8 on described spray medicine head 3 is evenly arranged, and aperture is 1.5～3.0mm.
Before use, pull back piston 6, negative pressure cylinder 1 is at suction function suction anesthetis, and spin screw thread 5 and nut 4, shifted onto spray medicine head 3 execute numb position by hard long duct 2, pushes forward piston 6 to, and anesthetis evenly sprays by medicine outlet hole 8.
