Abstract
The utility model relates to a disposable syringe with adjustable inserting needle depth. The disposable syringe comprises a syringe and an inserting needle depth controller arranged on a shell of the syringe. The shell of the syringe is provided with a bulge matched with the inserting needle depth controller that is a cylinder body or a semi-cylinder body matched with the shell of the syringe; the cylinder body or the semi-cylinder body is provided with a longitudinal sliding channel the side of which is provided with a plurality of blocking slots communicated therewith. When in use, the inserting needle depth can be determined according to the condition of a patient, then the inserting needle depth controller is glided up and down, and after the bulge on the shell of the syringe reaches a set position, the inserting needle depth controller is rotated to block the bulge on the shell of the syringe in the corresponding blocking slot of the inserting needle depth controller. During injection, no matter how high strength an operator exerts, the inserting needle just finishes injection according to the preset depth owing to the blocking and positioning function of the inserting needle depth controller. Being economical and practical, simple in manufacture process, low in cost and easy for operation, the disposable syringe has high clinical application rate.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, especially a kind of disposable syringe of scalable depth of needle.
Background technology
Intramuscular injection is a kind of nursing procedure technology of generally using for the patient treatment disease clinically.The needle length of tradition intramuscular injection device is fixed, can not regulate depth of needle, and the fat or thin of patient there are very big difference, particularly cancer of late stage and wasting diseases patient seriously to become thin clinically, also have the thin partially patient of young child and health, subcutaneous tissue is thinner.Simultaneously, clinically because the depth of needle that the difference of injection system requires is also different.
At present, the nurse mainly by the difference of nurse according to patient's concrete condition and injection system, grasps size firmly by rule of thumb and controls depth of needle when carrying out the intramuscular injection operation clinically.Therefore often exert oneself to cause inserting needle to cross deeply and sting bone to thin partially patient when excessive.Exert oneself to cause depth of needle to carry out the inserting needle second time inadequately and again to adiposis patient when too small.Particularly firm this type of phenomenon of the easier generation of young nurse in hospital.So not only increased unnecessary misery, also easily made the patient produce discontented mood and cause medical tangle simultaneously to the patient.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of disposable syringe of simple in structure, easy to use, the scalable depth of needle that is easy to grasp depth of needle is provided.
For achieving the above object, this utility model adopts following technical proposals:
A kind of disposable syringe of scalable depth of needle comprises syringe, and syringe shell is provided with a depth of needle controller.
Described syringe shell is provided with a projection that matches with the depth of needle controller.
Cylinder or the semicircle cylindrical shell of described depth of needle controller for matching with syringe shell, cylinder or semicircle cylindrical shell are provided with a vertical chute, and the chute side is provided with some and draw-in groove its UNICOM.
Described chute and draw-in groove all match with projection on the injector housing.
This utility model can also be provided with scale on the pin depth controller, the location needs during with convenient the use.
When this utility model uses, can determine depth of needle according to patient's the concrete condition and the difference of injection system, slide up and down the depth of needle controller then, after the projection on the injector housing arrives desired location, rotate the depth of needle controller projection on the injector housing is stuck in the corresponding draw-in groove of depth of needle controller.When injecting, the unattended operation person is with great strength inserting needle, because the location that stops of depth of needle controller is arranged, inserting needle all can be finished injection according to the degree of depth of prior setting.
This utility model had both satisfied the requirement of the required depth of needle of different clinically injection systems, had also alleviated patient's misery, and patient satisfaction is heightened, and had reduced medical tangle.Also improved simultaneously the technology content of clinical nursing activity.
This utility model clinical practice amount is big, and is economical and practical, and processing technology is simple, and cost is low, easy to operate.
Description of drawings
Fig. 1 is this utility model structural representation;
Wherein 1. syringes, 2. depth of needle controller, 3. projection, 4. chute, 5. draw-in groove.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
Among Fig. 1, syringe 1 shell is provided with a depth of needle controller 2.Syringe 1 shell is provided with a projection 3 that matches with depth of needle controller 2.
Depth of needle controller 2 cylinder or semicircle cylindrical shell for matching with syringe 1 shell, cylinder or semicircle cylindrical shell are provided with a vertical chute 4, and chute 4 sides are provided with three draw-in grooves 5 with its UNICOM.
Chute 4 and draw-in groove 5 all match with projection 3 on syringe 1 housing.
This utility model can also be provided with scale on depth of needle controller 2, the location needs during with convenient the use.
When this utility model uses, can determine depth of needle according to patient's situation and injection system, slide up and down depth of needle controller 2 then, after the projection on syringe 1 housing 3 arrives desired location, rotate depth of needle controller 2 projection 3 on the injector housing 1 is stuck in the depth of needle controller 2 corresponding draw-in grooves 5.When injecting, the unattended operation person uses great strength, because the location that stops of depth of needle controller 2 is arranged, inserting needle all can be finished injection according to the degree of depth of prior setting.
