Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
In describing the invention, it should be noted that, orientation or the position relationship of the instruction such as term "front", "rear", " interior ", " outward " are based on orientation shown in the drawings or position relationship, only the present invention for convenience of description and simplified characterization, instead of indicate or imply that the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as limitation of the present invention.
In describing the invention, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition above-mentioned term concrete meaning in the present invention can be understood.
In order to improve the convenience of injecting liquid drug operation, simplify the operation easier of injecting liquid drug, improve success rate and the accuracy of the target site injection of more difficult contact, the invention provides a kind of liquid ejector sleeve, the pipe box of liquid ejector sleeve and tip disalignment, both central shafts become obtuse angle angle, compared with the structure that prior art middle sleeve and tip are linearly, the tip being arranged on pipe box leading section is bending-like, when hand-held liquid ejector sleeve carries out liquid injection, the tip of bending is convenient near target site, and handled easily human users improves accuracy and the precision of liquid injection.
Particularly, shown in Fig. 4, the present embodiment liquid ejector sleeve comprises tip 1, tube head 2, pipe box 3, gum cover head 4, push rod 5, pushes away handle 6 and gum cover 7, pipe box 3 comprises leading section and the rearward end of connection, the central shaft of leading section and rearward end forms obtuse angle angle, and pipe box 3 leading section arranges tube head 2, and tip 1 is connected on tube head 2, tube head 2 and pipe box 3 are integrated, the central shaft of tip 1 and the central shaft conllinear of pipe box 3 leading section; Push rod 5 movably embeds in pipe box 3, and push rod 5 front end arranges gum cover head 4, and gum cover 7 is arranged on described gum cover head 4, and push rod 5 rear end arranges and pushes away handle 6, gum cover head 4, push rod 5 and push away handle 6 and be integrated.
In said structure, medicinal liquid is accurately injected into patient goal position by tip 1 under thrust, tube head 2 fixes tip 1, be beneficial to tip 1 through target site in small space, pipe box 3 stores medicinal liquid, create closed environment, be convenient to apply pressure, promote medicinal liquid and run forward, gum cover head 4 fixes gum cover 7, push rod 5 promotes liquid, pushes away handle 6 and applies pressure, and gum cover 7 and pipe box 3 are combined closely, the promotion medicinal liquid do not omitted runs forward, the diameter of gum cover 7 is not less than the diameter of pipe box 3, to ensure the seal of sleeve pipe 3.
Above-mentioned liquid ejector sleeve may be used for syringe, now tip is set to injection needle, also can use it for the spray of liquid, now tip is set to the required injector head used.
In order to the facility operated, push rod 5 is set to be greater than the length of pipe box 3 with the length sum pushing away handle 6, sleeve pipe 3 rearward end opening excircle is provided with the ring baffle axially vertical with sleeve pipe 3, for time hand-held to finger block, pushing away handle 6 rearward end opening excircle and be provided with the ring baffle axially vertical with sleeve pipe 3, is also the block being convenient to point.In order to the safety of medical science and the stability of liquid ejector sleeve performance, gum cover 7 is made up of vulcanite, and remaining part adopts perceptual medical plastic to make.
The present embodiment liquid ejector sleeve, in the confined space that pipe box provides, applies certain pressure to pushing away handle artificially, makes push rod and gum cover promote medicinal liquid and runs forward, be injected into the target site of patient by tube head, tip.The specific works process of liquid ejector sleeve and operation principle are: before liquid ejector sleeve sucks medicinal liquid, gum cover in it is pushed into bottom, drain air, then the tip of liquid ejector sleeve stretches into medicinal liquid, when plug gradually pull-up time, the pressure of plug front end is less than atmospheric pressure, and the pressure in medicinal liquid face equals atmospheric pressure, and under differential pressure action, medicinal liquid is just inhaled in liquid ejector sleeve.Applying certain pressure to pushing away handle artificially again, making push rod and gum cover promote liquid and running forward, being injected into the target site of patient by tube head, tip.
As can be seen from the above embodiments, the present invention to become two parts of obtuse angle angle with rearward end by pipe box being set to leading section, the tip being arranged on pipe box leading section is made to be bending-like, when hand-held liquid ejector sleeve carries out liquid injection, the tip of bending is convenient near target site, handled easily human users, improves accuracy and the precision of liquid injection.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
