Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a syringe with high safety. Background Technique

[0002] A syringe is a common medical appliance. As early as in the 15th century, the Italian Cartinel put forward the principle of the syringe. It is mainly used to draw or inject gas or liquid with a needle. The syringe can also be used in medical equipment and containers, such as scientific instruments in some chromatographic methods for injection through a rubber diaphragm. When the existing syringe is pulled out after use, due to the insecure fixation of the fixed end of the needle, there is a high probability that the needle will shake and cause harm to the human body, and the safety is poor. In view of the above problems, this application designs a syringe with high safety. Content of the Utility Model

A fixing shaft is fixedly connected to the outside of the right end of the medicine storage chamber around the medicine outlet, and an injection needle is arranged inside the fixing shaft.

[0007] To facilitate the injection of the medicine, the utility model is improved in that a pushing groove is opened at the left end of the medicine storage chamber, which is communicated with the inside of the medicine storage groove. A sealing head is slidably connected inside the pushing groove. The left end of the sealing head is fixedly connected with a pushing plate, the left end of the pushing plate is fixedly connected with a pushing rod, and the right end of the pushing rod is fixedly connected with a stress plate.

[0008] To prevent the sealing head from sliding out of the pushing groove when sucking the medicine, the utility model is improved in that a sealing groove is opened on the pushing plate, and a sealing rubber ring is arranged inside the sealing groove.

[0009] To protect the injection needle during transportation, the utility model is improved in that the right end of the medicine storage chamber is detachably connected with a sealing cover, and a placing groove is opened at the left end of the sealing cover, and the size of the placing groove matches the size of the injection needle.

[0010] In order to facilitate breaking off the injection needle, the present utility model is improved in that a breaking groove is provided at the middle position of the surface of the sealing cap, and the thickness of the breaking groove is smaller than the thickness of other positions of the sealing cap.

[0011] In order to prevent the force-bearing plate from slipping in the hand during injection, the present utility model is improved in that an anti-slip coating is provided at the left end of the force-bearing plate.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the present utility model provides a syringe with high safety, having the following

[0014] beneficial effects:

[0015] This syringe with high safety realizes secondary fixation of the needle through the cooperation of the medicine storage chamber and the fixing mechanism.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, A highly secure syringe, including a medicine storage chamber 1, on which a fixing mechanism for fixing the needle is provided. The fixing mechanism includes a medicine outlet 2, which is opened at the right end of the medicine storage chamber 1. The medicine outlet 2 is communicated with the inside of the medicine storage chamber 1. A fixing shaft 3 is fixedly connected to the periphery of the right end of the medicine storage chamber 1. An injection needle 4 is arranged inside the fixing shaft 3. A pushing groove 5 is opened at the left end of the medicine storage chamber 1. The pushing groove 5 is communicated with the inside of the medicine storage groove. A sealing head 6 is slidably connected in the pushing groove 5. The left end of the sealing head 6 is fixedly connected with a pushing plate 7. The left end of the pushing plate 7 is fixedly connected with a pushing rod 8. The right end of the pushing rod 8 is fixedly connected with a stress plate 9. The right end of the medicine storage chamber 1 is detachably connected with a sealing cover 12. A placement groove 13 is opened at the left end of the sealing cover 12. The size of the placement groove 13 matches the size of the injection needle 4.

[0023] When using this device, first remove the sealing cover 12 from the medicine storage chamber 1, then fix the injection needle 4 between the medicine outlet 2 and the fixing shaft 3. The fixing shaft 3 fixes the injection needle 4. Then insert the injection needle 4 into the required medicine. Then pull the stress plate 9 outward. The stress plate 9 drives the pushing rod 8 to move. The pushing drives the pushing plate 7 to move. The pushing plate 7 drives the sealing rubber and the sealing head 6 to move. The sealing groove 10 moves to make the inside of the pushing groove 5 in a vacuum state to suck the medicine into the medicine storage chamber 1. Then inject the medicine into the patient. After the medicine injection is completed, cover the sealing cover 12 at the injection needle 4, and then break off the injection needle 4 from the breaking groove 14.

[0024] In actual use, it is found that when sucking the medicine into the pushing groove 5, the sealing head 6 will slide out of the pushing groove 5. To avoid the above problem, in this embodiment, a sealing groove 10 is opened on the pushing plate 7, and a sealing rubber ring 11 is arranged in the sealing groove 10

[0025] In actual use, it is found that when destroying the syringe, the operator is easily pricked by the injection needle 4. To avoid the above problem, in this embodiment, a breaking groove 14 is opened at the middle position of the surface of the sealing cover 12, and the thickness of the breaking groove 14 is less than the thickness of other positions of the sealing cover 12.

[0026] In actual use, it is found that when pushing the stress plate 9, the stress plate 9 is easy to slide out of the hand. To avoid the above problem, in this embodiment, an anti-slip coating is provided at the left end of the stress plate 9.
