Second one end for going out sap cavity is provided with the second filter membrane.The syringe can be filtered to medical fluid with filter and and syringe
It is detachably connected, which is provided with strainer in syringe location, is filtered by strainer, but since needle tubing section is smaller, filters
The filtrable limited flow of net institute, and it is easy blocking, cleaning is difficult.
Summary of the invention
In order to improve above situation, syringe of the present invention provides a kind of pair of syringe needle amount of penetrating and controls, and to syringe needle
The syringe for being supported, and medical fluid being filtered by filtering screen arranged at the bottom.It can be right in injection process
Syringe needle is supported, and is prevented from falling off or further be penetrated.
Syringe of the present invention is achieved in that syringe of the present invention by cylinder, drive end bearing bracket, sealing ring, fixed frame, needle
Head, rubber mat, piston boit, push rod, casing, bottom cover, filtering screen, interior diaphragm and piston plate composition, the cylinder both ends difference
For uncovered structure, bottom cover is removably placed in cylinder bottom end, and the bottom cover and cylinder bottom end are clamping, and drive end bearing bracket is detachable
Be placed in cylinder top, the drive end bearing bracket and cylinder top are clamping, are opened on the drive end bearing bracket there are two through hole, piston plate is set
In in cylinder, the piston plate outer ring is equipped with sealing ring, and fits with cylinder inboard wall, and two push rod one end are respectively and piston rod
It is connected, the other end is pierced by from two through holes on drive end bearing bracket, and fixed frame and two push rod other ends are connected, the fixation
Frame is made of middle part link block and two connecting plates, and two connecting plates are respectively placed in the two sides of middle part link block, and two respectively
The push rod other end is correspondingly connected with, and the connecting plate side is equipped with rubber mat, is provided with mounting hole, the mounting hole in the middle part of the drive end bearing bracket
Between two through holes, casing is placed in cylinder, and one end is connected with drive end bearing bracket, on described sleeve pipe one end and drive end bearing bracket
The corresponding connection of mounting hole, the described sleeve pipe other end passes through in the middle part of piston plate, and is placed in casing, described sleeve pipe lateral wall and
Sliding sleeve is equipped between piston plate, piston boit is slidably disposed in casing, and described piston boit one end is pierced by out of mounting hole, institute
Sealing ring there are two setting on the outside of piston boit is stated, and is fitted with internal surface of sleeve pipe, is provided with injection canal in the middle part of the piston boit, it is described
Injection canal extends to the other end from piston boit one end, and the injection canal diameter is a quarter of casing diameter, syringe needle one
End is connected with piston boit one end, and the syringe needle other end is pierced by from middle part link block middle part, and the syringe needle is from middle part link block
The length for being pierced by part is equal to the intracorporal length of insertion needed for syringe needle, and the syringe needle and middle part link block are detachably connected, described
Syringe needle with injection canal is corresponding is connected to, the syringe needle internal diameter is equal to injection canal internal diameter, and the bottom cover middle position is provided with
Through-hole, interior diaphragm are removably placed on bottom cover inner wall, and the position of corresponding through-hole is protruding upward, the interior diaphragm edge card
It is placed between cylinder and bottom cover, the interior diaphragm is made of softwood matter, and filtering screen is pressed on interior diaphragm, and is located at interposition
It sets, the through-hole is located inside filtering screen, the filtering screen middle position formation tubulose protruding upward, and it is another to be placed in casing
In one end.
In use, bottom cover is removed first, medical fluid is poured into cylinder when carrying out drug injection, then again the bottom of by
End cap is mounted in cylinder bottom end, and medical fluid is stored in the cavity between piston plate and bottom cover, then medical staff by syringe needle prick into
In patient's blood vessel, until fixed frame is pressed in the patient's body surface, rubber mat and body surface fit, and syringe needle under fixed frame blocking, prick by syringe needle
Enter depth to be limited, without artificially being controlled, and fixed frame is supported syringe needle, and syringe needle is avoided to fall off, and syringe needle penetrates
Afterwards, cylinder is pushed to body surface direction, cylinder drives bottom cover and casing mobile, and bottom cover is mobile to piston plate direction, filter screen
Cover follows bottom cover and casing mobile, and opposite sliding, and then the cavity between piston plate and bottom cover occur for piston boit and casing
Gradually reduce, medical fluid enters in casing after filtering screen filters, and filter screen filters out the sediment in medical fluid, prevent into
Entering and blocks syringe needle into casing, the medical fluid in casing enters in the injection canal in piston boit, with the continuous entrance of medical fluid,
