Abstract
The utility model discloses a special-purpose contrast medium injection device for defecography, which is characterized by comprising a syringe, an injection pipe, a handle pipe, an injection pushing rod and a pushing handle, wherein the head portion of the syringe is provided with an injection port, a disposable injection pipe is arranged on the injection port, a piston gasket is blocked in the injection pipe, the center of the piston gasket is inserted and sleeved with the handle pipe, the injection pushing rod is arranged in the handle pipe, the injection pushing rod passes through from a center hole of the piston gasket, a slot hole is opened on the pipe wall of the handle pipe, the tail portion of the injection pushing rod is provided with the pushing handle, and the pushing handle extends outside the pipe wall of the handle pipe from the slot hole. Compared with the prior art, the special-purpose contrast medium injection device for defecography is convenient and rapid and convenient to operate, and saves contrast medium.
Description
[technical field]
This utility model relates to a kind of radiography appurtenance, particularly a kind of contrast medium injection apparatus that is applicable to that defecography is special-purpose.
[background technology]
Defecography is through injecting contrast agent to patient's rectum, and the inspection method that dynamic and static combination is observed is carried out at the anorectal region position during to patient " defecation ".It can show the functional and organic disease at anorectal region position, for the diagnoses and treatment of constipation clinically provides foundation.Concrete operations are: inspection day before yesterday afternoon 2,4, the 8h Folium Sennae 9～15g that takes after mixing it with water, to remove stercoroma.During inspection, earlier conduit is inserted anus under perspective, inject the about 50ml of barium liquid, make it to get into sigmoid colon and descending colon far-end; Extract conduit, insert Enemata anal tube, inject the pasty state contrast agent to anus.But be to use Enemata anal tube, can retain a large amount of pasty state contrast agent in the Enemata anal tube after injection finishes, cause great waste.And the use Enemata anal tube, the contrast agent of pasty state is not easy to be injected in the anus, complicated operation.
[utility model content]
The technical assignment of this utility model is the deficiency to above prior art, provides a kind of defecography special-purpose contrast medium injection apparatus.
The technical scheme that this utility model solves its technical problem is: the special-purpose contrast medium injection apparatus of a kind of defecography is characterized in that: comprise syringe, ascending pipe, handle tube, inject bar and push away handle, establish inlet at the head of described syringe; Sheathed disposable ascending pipe on it; Card is established the piston packing ring in syringe, and its central sleeve handle tube is established one and injected bar in the handle tube; Injecting bar passes from the medium pore of piston packing ring; Offer slotted eye on the tube wall of handle tube, the afterbody of injecting bar is established and is pushed away handle, and it stretches out the tube wall of handle tube from slotted eye.
Above-mentioned syringe, handle tube are that transparent material is processed.
Above-mentioned syringe outer tube wall is provided with rule.
The above-mentioned front end of injecting bar is taper.
Compared with prior art, the utlity model has following outstanding beneficial effect:
1, owing to taked technique scheme; When so this utility model uses; Earlier disposable ascending pipe is enclosed within on the inlet of syringe, advances handle tube again, piston packing ring extruding pasty state contrast agent gets into disposable ascending pipe; Be advanced into disposable ascending pipe injecting bar then, make pasty state contrast agent wherein inject anus fully.Just can not retain the pasty state contrast agent in the disposable like this ascending pipe, and discarded by in vain, guaranteed all to use up the pasty state contrast agent, avoided waste, for the patient has saved medical expense;
2, the bar propelling is injected in use, and is convenient and swift, is convenient to operation.
[description of drawings]
Fig. 1 is the structural representation of this utility model.
[specific embodiment]
Below in conjunction with the Figure of description and the specific embodiment this utility model is further specified.
As shown in Figure 1, this utility model comprises syringe 1, ascending pipe 3, handle tube 5, injects bar 6 and pushes away handle 8, establishes inlet 2 at the head of described syringe 1; Sheathed disposable ascending pipe 3 on it, card is established piston packing ring 4, its central sleeve handle tube 5 in syringe 1; Establish one in the handle tube 5 and inject bar 6; Inject bar 6 and pass from the medium pore of piston packing ring 4, offer slotted eye 7 on the tube wall of handle tube 5, the front end 10 of injecting bar 6 is taper; Afterbody is established and is pushed away handle 8, and it stretches out the tube wall of handle tube 5 from slotted eye 7.Described syringe 1, handle tube 5 are processed for transparent material.Described syringe 1 outer tube wall is provided with rule 9.
Need to prove; The particular of this utility model is described in detail this utility model; For a person skilled in the art, in the various conspicuous change of under the situation of spirit that does not deviate from this utility model and scope it being carried out all within the protection domain at this utility model.
