Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of double needle syringe.
Background technology
Traditional hypodermic syringe that is used for has only a syringe needle, and from the consideration that alleviates the patient suffering, the diameter of syringe needle is less usually, and its aperture is also less accordingly.When adopting powdery medicine to inject, need in syringe, suck water for injection, insert syringe in the container of powdery medicine then, water for injection is pushed in the container with the dilution medicine, obtain drug solution.Often mixing in the drug solution that obtains by this method has undissolved drug particles, because the aperture of syringe needle is less, with the drug solution inhalation syringe time, undissolved drug particles can stop up syringe needle.
The utility model content
The purpose of this utility model promptly is to overcome the deficiency of prior art, and a kind of not susceptible to plugging double needle syringe is provided.
The purpose of this utility model realizes through following technical scheme:
The double needle syringe, it comprises cylindrical shell, is positioned at tube intravital piston and the push rod that is connected with piston, and the bottom of cylindrical shell is provided with check valve A and check valve B; Check valve A and check valve B are V-shape and arrange; The input of check valve A is positioned at outside the cylindrical shell, and the outfan of check valve A is positioned at cylindrical shell, and the input of check valve B is positioned at cylindrical shell; The outfan of check valve B is positioned at outside the cylindrical shell, and the outfan of the input of check valve A and check valve B is provided with tapped swivel nut;
It also comprises syringe needle A and syringe needle B, and the end of syringe needle A and syringe needle B is provided with installation tube, and installation tube is provided with external screw thread, and syringe needle A is connected with swivel nut on the check valve A through installation tube, and syringe needle B passes through installation tube and is connected with swivel nut on the check valve B.
The aperture of syringe needle A is greater than the aperture of syringe needle B.
The input of check valve B is provided with filter screen.
The advantage of this utility model is:
1. draw drug solution with syringe needle A, with syringe needle B injection, the aperture of syringe needle A is bigger, is difficult for stopping up, and the external diameter of syringe needle B is less, can not increase patient's misery;
2. be provided with two check valves that flow direction is opposite, when drawing or inject, having only in the syringe needle has liquid to pass through;
3. the V-shaped arrangement of check valve has increased the spacing between two syringe needles, handled easily.
