Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 5, a novel syringe special for intravenous injection comprises a needle tube 1, a needle head 2 and a needle cap 3, wherein a piston 4 is slidably connected inside the needle tube 1, the piston 4 is made of red rubber, a threaded push rod 5 is rotatably connected to the top of the piston 4, a rocking handle 6 is sleeved on the top of the threaded push rod 5, a threaded sleeve 8 is in threaded connection with the surface of the threaded push rod 5, a limiting hole 9 is formed in the surface of the threaded sleeve 8, a handle 10 is welded to the mouth of the needle tube 1, a sliding hole 11 is formed in the handle 10, a limiting rod 13 is slidably connected inside the sliding hole 11, the limiting rod 13 is matched with the limiting hole 9, a cap 14 is arranged at the bottom of the surface of the needle tube 1, and the needle head 2, the needle cap 3, the piston 4, the threaded push rod 5, the rocking handle 6, the threaded sleeve 8, the limiting hole 9, the handle 10, the sliding hole 11, the limiting rod 13 and, it is comparatively concentrated to have solved the ward patient, the nurse generally can carry many syringes to inject respectively for many patients, but the syringe specification is the same, cause the nurse to differentiate to make mistakes very easily, lead to the patient medicine to obscure, and then take place medical dispute, and nurse's strength is limited, the medicine is injected the speed and is difficult to hold, often cause the uncomfortable problem of using medicine for the patient, possess the advantage of being convenient for discernment and control push away the speed, the condition of needle cylinder chooseing for use wrong has effectively been avoided the nurse to carry out intravenous route for the patient, patient itself has been protected, avoid medical dispute, improve the security of using medicine and patient's satisfaction, therefore, the multifunctional infusion set is very practical, and is worthy.

Further, the fixed pin 15 has been welded on the surface of gag lever post 13, and spout 16 has been seted up to the inner wall of sliding hole 11, and the surface of fixed pin 15 and the inner wall sliding connection of spout 16, through setting up fixed pin 15 and spout 16, effectively avoid gag lever post 13 slippage.

Furthermore, the top butt fusion on 8 surfaces of thread bush has spacing piece 17, through setting up spacing piece 17, the descending height of the spacing thread bush 8 of being convenient for makes things convenient for gag lever post 13 to peg graft with spacing hole 9.

Further, the top of the piston 4 is sleeved with a bearing 18, the bearing 18 is rotatably connected with the bottom of the threaded push rod 5, and the rotation flexibility of the piston 4 and the threaded push rod 5 is enhanced by arranging the bearing 18.

Further, the surface processing of block 14 has integrative antislip strip 12, and antislip strip 12 is located 360 even settings in the surface of block 14, through setting up antislip strip 12, strengthens block 14 frictional force, is convenient for cup joint.

Furthermore, scales 7 are integrally processed on the surface of the needle tube 1, and the situation of pushing speed of the liquid medicine can be conveniently checked by arranging the scales 7.

The working principle is as follows: when the injector is used, the needle cap 3 is taken down, whether the piston 4 is a red piston 4 is checked, then the needle head 2 is inserted into a liquid medicine for intravenous injection, the threaded push rod 5 is pulled through the rocking handle 6, the piston 4 is pulled through the threaded push rod 5 through the bearing 18, after the liquid medicine is extracted, the needle head 2 is taken down, the cap 14 is sleeved on the head of the needle tube 1, the threaded sleeve 8 is rotated until the limiting piece 17 is attached to the handle 10, the limiting rod 11 in the sliding hole is pushed to be inserted into the limiting hole 9, if the limiting rod 13 is dislocated with the limiting hole 9, the position of the limiting hole 9 can be rapidly found through rotating the threaded push rod 5, a plurality of different needle tubes 1 are taken to a ward for patients to use, when the injector is used, the intramuscular injection needle tube generally only needs to push injection, if the selection is wrong, the threaded push rod 5 can be found to be incapable of pushing, namely, the needle tube 1 is special for intravenous injection, when, rotate screw thread push rod 5 through rocking handle 6, screw thread push rod 5 passes through 8 rotatoryly downwards of thread bush and promotes piston 4, carries out the medicine and injects, looks over the liquid medicine through scale 7 and injects the condition, and the medicine pushes away the speed and easily masters.
