Technical field
This utility model relates to a kind of urinary system medical apparatus and instruments, is specially a kind of retrograde urethrography syringe.
Background technology
When diseases of urinary system is diagnosed, need to carry out radiography to urinary tract at present.During radiography, patient lies on the back on x ray lathe, by catheter or by the direct per urethra mouth of syringe nipple, inserts urethra, and contrast agent is injected to urethra.Excessive for preventing contrast agent, urethra front port need to be clutched, because doctor firmly clamps urethral orifice to stop contrast agent to leak by hands, dynamics is difficult to grasp, and often can bring very big misery to patient.Therefore in the urgent need to a kind of urethrography injection device that can effectively prevent that contrast agent from leaking and can effectively avoid patient's misery.
Summary of the invention
This utility model, for solving contrast agent in current urethrography process and easily leak and easily cause the technical problem of patient's misery, provides a kind of retrograde urethrography syringe.
This utility model is realized by the following technical solutions: a kind of retrograde urethrography syringe, comprise an opacifying injection pipe, and described opacifying injection pipe comprises a conical cylinder and the hemispherical projection that is located at conical cylinder end face; Opacifying injection pipe inside is provided with the fluid passage of up/down perforation; The external diameter of described conical cylinder end face and the diameter of hemispherical projection are 3 ~ 7mm, and the external diameter of conical cylinder bottom surface is 10 ~ 20mm; The length of opacifying injection pipe is 45 ~ 75mm.
During use, the end of the hemispherical projection of retrograde urethrography syringe is entered to human body through lubricated by urethral orifice, after entering, the injection head of outer injectors is inserted to fluid passage, contrast-medium injection is entered to human body urinary system and carry out radiography.The conical design of retrograde urethrography syringe can make the end of retrograde urethrography syringe that urethra is blocked naturally, without doctor, firmly clamping urethral orifice can effectively stop contrast agent to leak, simplify doctor's operation easier, also reduced patient's pain simultaneously.The external diameter size of end face and bottom surface meets organization of human body, can make whole device enter smoothly human body and people's sense of discomfort minimum in conjunction with the design of hemispherical projection.
Further, also comprise the opacifying injection head matching with opacifying injection pipe; Described opacifying injection head comprises the injection needle matching with fluid passage and the taper being connected with injection needle; Described injection needle stretches in fluid passage and the length of injection needle is less than the length of fluid passage; The outer wall of injection needle and the inner wall sealing of fluid passage are fixed.
Opacifying injection head inserts in the fluid passage of opacifying injection pipe, and the length of injection needle is less than the length of fluid passage, and the front end of syringe needle just can not expose the upper port of opacifying injection pipe like this, has avoided the injury to patient's urinary tract; The outer wall of injection needle and the inner wall sealing of fluid passage are fixed, and have so just avoided the backflow of contrast solution.Had opacifying injection head, during injection of contrast medium, as long as outer injectors is just connected and can be used with the inlet seal of taper by pipeline, the design of taper has facilitated and being connected of outer injectors.
Further, described fluid passage comprises the syringe needle passage from upper port to downward-extension and connects with syringe needle passage lower port and connect the tapered channel of conical cylinder bottom surface; Also comprise opacifying injection head; Described opacifying injection head comprises the injection needle matching with syringe needle passage and the taper that is connected and matches with tapered channel with injection needle; Described injection needle stretches in syringe needle passage, and the inner wall sealing of the outer wall of injection needle and syringe needle passage is fixed; The length of described injection needle is less than the length of syringe needle passage.
Fluid passage is divided into two parts, and tapered channel plays spacing effect to taper, and opacifying injection head just can partly or entirely be inserted in the fluid passage of opacifying injection pipe like this, and the two being made of one, is convenient for carrying and uses.
This utility model is by the tapered cylindrical structure of retrograde urethrography injector designed, and without doctor, firmly clamping urethral orifice can effectively stop contrast agent to leak, and has simplified doctor's operation easier, has also reduced patient's pain simultaneously.This utility model is simple in structure, safe and convenient to use, is easy to produce, and efficiently solves the technical problem running in prior art.
