Abstract
The utility model discloses an injector for a medical department. The injector for the medical department comprises an injection barrel, a piston is mounted in the injection barrel, a piston rod is mounted behind the piston, and a needle head holder is mounted at the front end of the injection barrel and provided with a needle head; the injector further comprises a balancing block which is provided with two guide holes and a needle hole, two guide rods are mounted at the top end of the injection barrel, one guide rod is inserted in one guide hole while the other guide rod is inserted in the other guide hole, the needle head extends out of the needle hole, a buffer spring sleeves each guide rod, and one end of the buffer spring is connected with the balancing block while the other end is connected with the injection barrel. The injector for the medical department has beneficial effects that the structure is simple, the balancing performance of the injection barrel is greatly improved, the friction force between the injection barrel and the hand is increased so that the injection barrel is difficult to slip out of the hand, and the user is easy to observe the volume of the liquid medicine in the injection barrel.
Description
Technical field
This utility model relates to a kind of medical appliance, particularly a kind of internal medicine syringe.
Background technology
Existing syringe outer surface is smooth, occurs sometimes the situation of slippage during at extraction medicine or to patient infusion, and it is very inconvenient using, in addition, existing syringe is in injection, owing to just syringe needle being inserted in patient's body, thereby balanced capacity is poor.
Summary of the invention
Problem to be solved in the utility model is: provide a kind of simple in structure, be difficult for slippage and the strong internal medicine syringe of balanced capacity.
In order to address the above problem, internal medicine syringe of the present utility model, comprise injection tube, in described injection tube, be provided with piston, the rear portion of described piston is provided with piston rod, the front end of described injection tube is provided with needle holder, described needle holder is provided with syringe needle, it is characterized in that: also comprise a balance weight, described balance weight is provided with two pilot holes and a needle outlet, the top of described injection tube is provided with two guide rods, described guide rod is inserted in respectively in pilot hole, described syringe needle stretches out from needle outlet, on described guide rod, be socketed with buffer spring, described buffer spring one end is connected with balance weight, one end is connected with injection tube in addition.
In order to increase the coefficient of friction of syringe, prevent slippage when in use, internal medicine syringe of the present utility model, the outer surface of described injection tube is evenly equipped with several projections that increases friction use, is also provided with a handles on described injection tube.
For the ease of observe injection tube inner liquid medicine number, internal medicine syringe of the present utility model, the outer wall of described injection tube is provided with containing mark.
The beneficial effect that this utility model is obtained is: (1) is simple in structure; (2) comprise a balance weight, balance weight is provided with two pilot holes and a needle outlet, the top of injection tube is provided with two guide rods, guide rod is inserted in respectively in pilot hole, syringe needle stretches out from needle outlet, on guide rod, be socketed with buffer spring, buffer spring one end is connected with balance weight, one end is connected with injection tube in addition, thereby when giving patient infusion, in syringe needle inserts patient body after, balance weight can stick together with patient's skin, injection tube is effectively supported, greatly improved the balance quality of injection tube; (3) outer surface of injection tube is evenly equipped with several projections, is also provided with a handles on injection tube, thereby when picking and placeing syringe, is convenient to pick and place, and has increased the frictional force between injection tube and hands, makes it to be difficult for slipping out of the hand; (4) outer wall of injection tube is provided with containing mark, thereby is easy to observe the number of injection tube inner liquid medicine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, piston rod, 2, projection, 3, handle, 4, piston, 5, injection tube, 6, needle outlet, 7, syringe needle, 8, balance weight, 9, pilot hole, 10, guide rod, 11, buffer spring, 12, needle holder, 13, containing mark.
The specific embodiment
As shown in Figure 1, internal medicine syringe of the present utility model, comprise injection tube 5, in described injection tube 5, be provided with piston 4, the rear portion of described piston 4 is provided with piston rod 1, the front end of described injection tube 5 is provided with needle holder 12, described needle holder 12 is provided with syringe needle 7, also comprise a balance weight 8, described balance weight 8 is provided with two pilot holes 9 and a needle outlet 6, the top of described injection tube 5 is provided with two guide rods 10, described guide rod 10 is inserted in respectively in pilot hole 9, described syringe needle 7 stretches out from needle outlet 6, on described guide rod 10, be socketed with buffer spring 11, described buffer spring 11 one end are connected with balance weight 8, one end is connected with injection tube 5 in addition, the outer surface of described injection tube 5 is evenly equipped with several projections 2 that increases friction use, is also provided with a handles 3 on described injection tube 5, the outer wall of described injection tube 5 is provided with containing mark 13.
When medical personnel are to patient injection medicinal liquid time, first be that syringe needle 7 is inserted in patient's body, along with the insertion of syringe needle 7, balance weight 8 will stick together with patient's skin, injection tube 5 is effectively supported, greatly improved the balance quality of injection tube 5.
Due to the effect of buffer spring 11, medical personnel can regulate the pressure of pressing injection tube 5 according to actual state, thereby change syringe needle 7, insert the degree of depth in patient body, very convenient.
The outer surface of injection tube 5 is evenly equipped with several projections 2, is also provided with a handles 3 on injection tube 5, thereby when picking and placeing syringe, is convenient to pick and place, and has increased the frictional force between injection tube 5 and hands, makes it to be difficult for slipping out of the hand.
The outer wall of injection tube 5 is provided with containing mark 13, thereby is easy to observe the number of injection tube 5 inner liquid medicines.
