Abstract
The utility model discloses an environmentally-friendly syringe cylinder which is provided with a retractable cylinder body and is not provided with a piston, and overcomes the defect that more medical materials are needed generally and the liquid medicine leaks due to the separation of the piston. The environmentally-friendly syringe cylinder comprises a syringe needle (1) and a cylinder body (3), wherein the cylinder body (3) is a plastic folding pipe and is retractable; the front end of the cylinder body (3) is a holding seat (2) and the rear end of the cylinder body (3) is a pushing seat (4); the edge of the holding seat (2) is provided with a guiding column (5) parallel to the cylinder body, and the guiding column can be an elliptic cylinder or a triangular prism which can prevent the cylinder body from rotating; the edge of the pushing seat (4) is provided with a guiding hole (6) corresponding to the guiding column (5); a limiting rod (7) is arranged at the edge of the holding seat (2); the end of the limiting rod (7) is provided with a clamping hook; and correspondingly, a limiting hole (8) through which the clamping hook can pass is arranged at the edge of the pushing seat (4). The environmentally-friendly syringe cylinder disclosed by the utility model is suitable for any occasions in which the traditional medical syringe cylinders are used, and has the advantages of saving materials, avoiding environmental pollution, guaranteeing one-time use and the like.
Description
Technical field
This utility model relates to a kind of medical appliance, especially relates to a kind of medical syringe.
Background technology
Medical syringe is made up of syringe needle part, stack shell part and piston portion usually at present.The effect of syringe is with medicinal liquid inspiration stack shell from medicine bottle, is injected in the patient body again.
The armarium that medical syringe frequently uses as quilt, the disposable use of palpus, syringe needle, stack shell, piston all need be thrown aside after using, so a large amount of discarded syringes has not only been wasted many resources, have also caused reluctant medical waste.Moreover no matter before and after injection, when piston disengaging stack shell, medicinal liquid will contact the external world, pollutes and inconvenience.More than these all are not environmental protection.
Chinese patent publication number CN2787233, in open day on June 14th, 2006, the name of utility model is called the environment-friendly type syringe; This application case discloses a kind of environment-friendly type syringe, and it is to comprise body and syringe at syringe, and the body cylindrical is forward and backward fluted; Along this groove sectional body that fractures, body top and union joint clasp joint, union joint front end are cone shape; Screw thread is arranged on the cone, and be spirally connected with syringe needle one end taper hole female thread.Behind this needle cylinder injection patient; Body retreats to front end one circle groove from syringe, fractures along groove, and insert in the syringe front end sleeve pipe body rear end after fractureing; Groove along its rear end fractures; Like this, the residual liquor in the syringe is enclosed in the syringe by the body at syringe two, can not cause the pollution to environment.This utility model weak point is still need use more material.
The utility model content
This utility model has overcome general medical syringe needs the more and easy deficiency of deviating to cause medicinal liquid to leak because of piston of materials used, and a kind of province material environment-friendly type syringe is provided.
This utility model is realized through following technical scheme:
A kind of environment-friendly type syringe comprises syringe needle 1, stack shell 3, and said stack shell 3 is the plastic folded pipe; Can stretch; Its front end is for gripping seat 2, and the rear end is for pushing seat 4, and described seat 2 edges that grip are provided with the lead parallel with stack shell 5; Push seat 4 edges and be provided with the pilot hole 6 corresponding with lead 5, lead 5 and pilot hole 6 can play the effect of guiding.
As preferably, described seat 2 edges that grip are provided with gag lever post 7, and there is grab gag lever post 7 ends, and are corresponding, push seat 4 edges and are provided with the spacing hole 8 that can let grab pass.Can guarantee that so syringe can not suck air once more after injection finishes, syringe can not flowed out because of external world's extruding causes remaining medicinal liquid.
As preferably, described lead 6 is a cylindroid, can guarantee that stack shell is unlikely to cause rotation.
Therefore, the beneficial effect of this utility model is: material has been saved in (1); (2) the stack shell inner liquid medicine can not leak easily, avoids polluting; (3) can guarantee disposable use, avoid the lawless person that its recovery is reused.
Description of drawings
Fig. 1 is the structural representation of this utility model.
Fig. 2 is a front view that grips of this utility model.
Fig. 3 is a vertical view that grips of this utility model.
Among the figure: syringe needle 1, grip seat 2, stack shell 3, push seat 4, lead 5, pilot hole 6, gag lever post 7, spacing hole 8.
The specific embodiment
Like Fig. 1, Fig. 2, a kind of environment-friendly type syringe shown in Figure 3: comprise syringe needle 1, stack shell 3; Described stack shell 3 is the plastic folded pipe, and its front end is for gripping seat 2, and the rear end is for pushing seat 4; Described seat 2 edges that grip are provided with the lead parallel with stack shell 5, and lead 5 is provided with scale.Push seat 4 edges and be provided with the pilot hole 6 corresponding with lead 5.Described seat 2 edges that grip are provided with gag lever post 7, and there is grab gag lever post 7 ends, and are corresponding, push seat 4 edges and are provided with the spacing hole 8 that can let grab pass.
When using this utility model, syringe needle is inserted medicine bottle, to pin on the other hand and grip seat 2, another hands will push seat 4 and pull outward, and can extract medicinal liquid to stack shell 3.After extracting enough medicinal liquids, hand-held syringe will push seat 4 down, and syringe needle 1 up pushes seat up gently, and air is discharged stack shell 3, simultaneously according to the scale on the lead 5, and the control amount of liquid medicine.
During injection, syringe needle 1 is inserted injection place, push and push seat 4; Can injecting liquid drug be gone in the patient body; Because the guiding that grips the pilot hole 6 on the lead 5 of seat on 2 and the corresponding with it propelling movement seat 4 is arranged, and lead 5 can be cylindroid or triangular prism, thereby can not cause stack shell 3 rotations; And stack shell 3 is plastic folded pipes, can guarantee that then stack shell 3 can stretch vertically.When medicinal liquid is extruded stack shell 3 fully, push seat 4 and also come downwards to bottom dead centre, and the trip that has been passed through gag lever post 7 ends of spacing hole 8 blocks, can extract syringe needle 1 at this moment.So stack shell 3 just can not be stretched once more, and air can not get into stack shell 3, thereby remaining medicinal liquid can not exert pressure to stack shell 3 because of external force easily yet and flow out from syringe needle 1, causes the pollution of environment.After above-mentioned injection process is accomplished, hold on the other hand and grip seat 2 and push seat 4, another hands is exerted oneself a little, lead 5 is broken off with the fingers and thumb disconnected, and the syringe part function promptly is destroyed, and can't normally use, thereby guarantee that it can not reclaimed use by the lawless person once more.
