Detailed Description
The syringe of the single-handed needle of the present utility model will be described in more detail below with reference to the drawings, in which preferred embodiments of the present utility model are shown, it being understood that one skilled in the art may modify the utility model described herein while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.
The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. The advantages and features of the present utility model will become more apparent from the following description. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.
As shown in fig. 1 to 3, an embodiment of the present utility model proposes a syringe with a single-hand-adjustable needle, which includes a syringe body 1, a rotation-adjusting housing 2, and a buckle 3.
Specifically, the rotation adjusting housing 2 is sleeved outside the syringe body 1, and the rotation adjusting housing 2 is in clamping connection with the needle of the syringe body 1.
The buckle 3 is arranged on the needle cylinder of the injector body 1, and the buckle 3 is clamped with the rotary adjusting shell 2 to limit the rotary adjusting shell 2.
In this embodiment, before the injection of the medical fluid is performed, the rotation adjustment housing 2 is rotated, and at this time, the needle of the syringe body 1 is rotated together with the rotation adjustment housing 2 until the needle tip slope of the needle of the syringe body 1 is positioned on the same plane as the scale of the cylinder of the syringe body 1. At this time, the medical staff can push the piston rod of the injector body 1 and discharge the cylinder air in the injector body 1.
Compared with the needle head of the syringe body 1 which is directly rotated by medical staff, the pollution to the needle head of the syringe body 1 can be effectively reduced, and meanwhile, the medical staff can directly observe whether the liquid medicine flows out from the needle head of the syringe body 1 or not, so that the waste of the liquid medicine is avoided.
Further, the rotation adjusting housing 2 includes a driving portion 4 and a rotating portion 5, the driving portion 4 and the rotating portion 5 are integrally formed, the driving portion 4 is engaged with the needle of the injector body 1, and the rotating portion 5 is rotatably connected with the syringe of the injector body 1.
Specifically, when the needle position of the syringe body 1 is adjusted, the rotating part 5 is rotated, the driving part 4 rotates along with the rotating part 5, and the driving part 4 can drive the needle of the syringe body 1 to rotate along with the needle of the syringe body 1 until the needle inclined plane of the syringe body 1 is on the same plane with the needle cylinder scale of the syringe body 1 due to the clamping connection of the driving part 4 and the needle of the syringe body 1.
In a specific embodiment, an adjusting ring 6 is disposed at an end of the rotating portion 5 away from the driving portion 4, and anti-skidding patterns are disposed on an outer sidewall of the adjusting ring 6.
The tip of the needle of the syringe body 1 has a protrusion (this is a structure of the syringe in the prior art), and in order to achieve the engagement between the needle of the syringe body 1 and the driving portion 4, a groove matching with the protrusion may be provided on the inner wall of the driving portion 4.
In order to be able to clearly and intuitively observe the needle graduation of the syringe body 1, the rotary part 5 adopts a transparent housing.
Further, the rotating portion 5 is provided with a plurality of limiting holes 7 matched with the buckle 3, and the limiting holes 7 are circumferentially distributed on the side surface of the rotating portion 5.
Specifically, in order to make the rotation adjusting housing 2 stably stop at any rotation angle, the rotation part 5 is provided with a plurality of limiting holes 7 matched with the buckles 3, and when the buckles 3 enter different limiting holes 7, the needle head of the injector body 1 and the rotation adjusting housing 2 stop at the current rotation angle.
In order to enable the buckle 3 to smoothly enter different limiting holes 7, the inner ends of the limiting holes 7 are provided with chamfer structures. The buckle 3 can enter into the limiting hole 7 at the adjacent position along the inclined plane of the chamfer structure.
Further, the buckle 3 includes a fixing ring 8 sleeved in the rotating portion 5, and an airbag protrusion 9 matched with the limiting hole 7 is provided on the fixing ring 8.
Specifically, the inner wall of the rotating part 5 is in sliding contact with the surface of the fixed ring 8, and meanwhile, a storage groove matched with the air bag bulge 9 is formed in the fixed ring 8, and an air bag can be formed after the storage groove is sealed with the air bag bulge 9. When the buckle 3 enters into different limiting holes 7, the air bag bulge 9 is extruded and then enters into the storage groove, so that the air bag bulge is convenient to enter into different limiting holes 7.
In addition, after the airbag bulge 9 is extruded by the inner wall of the rotating part 5, the gas in the airbag is compressed, and when the airbag bulge 9 enters the next limiting hole 7, the airbag bulge 9 is bulged by the air pressure, so that the limiting of the rotating adjusting shell 2 is realized.
Compared with the prior art, the utility model has at least the following beneficial effects:
according to the utility model, the needle head of the injector body is driven to rotate by the rotary adjusting shell, the limit of the rotary angle of the rotary adjusting shell can be realized by matching with the buckle, the needle head inclined plane of the injector body and the needle cylinder scale of the injector body can be adjusted to the same side, the exhaust operation is convenient before the injection of the injector, the pollution to the needle head of the injector can be reduced, and the waste of liquid medicine can be reduced.
