Abstract
The utility model discloses a ring handle syringe, which comprises a jacket, a piston, a push rod and a cap. The jacket and the push rod are respectively provided with a ring-shaped operating handle and are also provided with corresponding scales, the front end of the jacket is provided with a connector seat, the connector seat is connected with a connector, a seal ring is arranged between the connector seat and the connector, one side of the push rod is a guide groove and a plurality of positioning troughs in the axial direction, a positioning ring is movably sleeved on the push rod, and the inner side of the positioning ring is provided with a convex block which is matched with the guide groove and the positioning troughs. Since the jacket and the push rod adopt the ring handle structure and are provided with the corresponding scales, the amount of medicine liquid injection can be limited under the matching effect of the positioning ring and the positioning groove on the push rod. The utility model has the advantages of simple structure, convenient injection, accurate measurement and positioning limitation, and is applicable to the injection of contrast agents and other types of medicine in the cardiovascular intervenient surgery.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically a kind of handle syringe.
Background technology
We know that syringe is a kind of medical apparatus commonly used, and it generally comprises overcoat, piston, push rod.Piston is installed in the push rod front portion, can be driven in overcoat by push rod to twitch back and forth, and the overcoat front end is provided with needle holder, is used for connecting injection needle joint or other.We also know, in the diagnosis and treatment of cardiovascular disease, contrast agent need be pushed into and carry out angiography in the blood vessel.Common syringe is inconvenient to operate and observe.China Patent No. 200720068378.0 has announced that a kind of contrast agent pushes device, it comprises the shot sleeve of tool swivel joint and handle and the push rod of natural rubber plug, push rod lid and handle, above-mentioned push rod is contained in the shot sleeve, wherein, the scale that milliliter is arranged on the push rod, the scale of the milliliter on this scale sequence and the sleeve puts in order consistent, the milliliter graduation mark of last figure and the corresponding coincidence of start index line on the push rod on the sleeve.Above-mentioned contrast agent pushes device and observes the scale facility, but the amount of pushing of contrast agent limits adjustment, operation makes things convenient for inadequately.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure is provided, and injection operation is convenient, maneuverability, and accurate measurement, and can locate the handle syringe of limiting the quantity of.
The technical scheme in the invention for solving the above technical problem is: a kind of handle syringe, it comprises overcoat, piston, push rod, block, be respectively equipped with annular operating grip on overcoat and the push rod, push rod and put outward and be provided with corresponding scale, the overcoat front end is provided with plinth, plinth connects a joint, between plinth and the joint sealing ring is installed, it is characterized in that: push rod one side shaft is to being provided with a direction recess and some locating slots, movable set one locating ring on the push rod, locating ring inboard are provided with a projection that cooperates with direction recess and locating slot.
The said locating slot of this utility model is positioned at direction recess one side, and is communicated with direction recess.
Said locating slot of this utility model and said projection shape match.
This utility model overcoat and push rod adopt the handle structure, and push rod and put outward and be provided with corresponding scale cooperates the injection volume of qualification medicinal liquid with the push rod locating slot by locating ring.Against existing technologies, this utility model simple structure, it is convenient that injection operation, scale are observed, accurate measurement, and can locate and limit the quantity of, good seal performance, it is applicable to contrast agent and the injection of other medicine in the cardiovascular intervene operation.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model locating ring.
1. push rods among the figure, 2. locating ring, 3. block, 4. overcoat, 5. piston, 6. joint, 7. sealing ring.
The specific embodiment
As can be seen from Figure 1, a kind of handle syringe of this utility model, it comprises overcoat 4, piston 5, push rod 1, block 3 etc., piston 5 is installed in push rod 1 front portion, can drive by push rod 1 and in overcoat 4, move around, the rear portion of overcoat 4 is equipped with block 3, block 3 is provided with the push rod through hole, be respectively equipped with annular operating grip on overcoat 4 and the push rod 1, push rod 1 and overcoat 4 are provided with corresponding scale, overcoat 4 front ends are provided with plinth, and plinth connects a joint 6, between plinth and the joint 6 sealing ring 7 are installed.Overcoat 4 and push rod 1 adopts handle operating grip structure, and be easy to operate, push rod and put outward and be provided with corresponding scale, and scale is observed and is made things convenient for.
Characteristics of the present utility model are: push rod 1 one side shafts are to being provided with a direction recess and some locating slots, movable set one locating ring 2 on the push rod, and locating ring 2 inboards are provided with a projection that cooperates with direction recess and locating slot, as shown in Figure 2.The said locating slot of this utility model is positioned at direction recess one side, and is communicated with direction recess.Said locating slot and said projection shape match.During work, when projection is arranged in direction recess, push rod 1 and locating ring 2 can relatively move, to guiding groove one side rotational positioning ring, in the locating slot that the locating ring projection is positioned to preset, locating slot and projection shape match, push rod 1 and locating ring 2 relative fixed no longer move axially.Define the moving range of push rod 1 in overcoat 4 by locating ring 2, and then define the injection volume of syringe medicinal liquid.The quantity of locating slot and position can require to set according to scale label on the push rod 1 and injection volume.
This utility model cooperates with the push rod locating slot by locating ring, limits the injection volume of medicinal liquid, its simple structure, it is convenient that injection operation, scale are observed, accurate measurement, and can locate and limit the quantity of, good seal performance, it is applicable to contrast agent and the injection of other medicine in the cardiovascular intervene operation.
