Problems solved by technology
[0002] The existing syringe is composed of a needle tube and a needle head. The liquid outlet of the needle tube is connected with the needle seat of the needle head through a tapered surface. When injecting a patient intramuscularly, sometimes the needle head and the needle tube are not tightly connected and the needle head falls off. At this time, it is easy to waste the liquid medicine, and the re-docking may generate air bubbles, which will reduce the injection efficiency and increase the pain of the patient

Embodiment Construction
[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] The fall-off prevention syringe is composed of a syringe 1, a sleeve 2, a retaining strip 3, a connection strip 4 and a liquid outlet 5, and the injection needle is composed of a check strip 6, a needle seat 7, a needle 8 and a wing 9. In the middle part of the front end face of the syringe 1 is a cylindrical liquid outlet 5 integral with the syringe 1, and on both sides of the liquid outlet 5 are a pair of sleeves with a symmetrical figure centered on the axis of the syringe 1. slice 2. Each sleeve 2 is a fan-shaped plastic sheet with the same center as the liquid outlet 5, and the outer circumference and clockwise straight side of the sleeve 2 are respectively connected to the end face of the syringe 1 through a linear joint 4 and an arc-shaped joint 4 bonding. There is also a retaining strip 3 with a semicircular cross section arranged along...

The invention relates to medical equipment, in particular to a thread-off prevention syringe and a syringe needle. The thread-off prevention syringe comprises a syringe, washers, barrier strips, a connecting strip and a liquid outlet, and the syringe needle comprises check strips, a needle stand, a pinhead and fins. A pair of washers is arranged on both sides of the liquid outlet symmetrically by taking the axle center of the syringe as a center, each washer is a sector plastic sheet concentric with the liquid outlet, the inner side of each washer is provided with the barrier strip which has a semicircular cross section and is arranged along the diameter direction of the washer, a pair of fins is arranged on the periphery of the bottom of the needle stand by taking the axis center of the pinhead as a center, the fins are of sector shapes on a plane, and one check strip is arranged on the outer side of the periphery in the anti-clockwise direction of each fin. The invention completely eradicates the possibility of the separation of the syringe needle from the syringe in the process of use.
Description
technical field [0001] The invention relates to a medical device, in particular to an anti-off syringe and an injection needle. Background technique [0002] The existing syringe is composed of a needle tube and a needle head. The liquid outlet of the needle tube is connected with the needle seat of the needle head through a tapered surface. When injecting a patient intramuscularly, sometimes the needle head and the needle tube are not tightly connected and the needle head falls off. , At this time, it is easy to waste the liquid medicine, and the re-docking may generate air bubbles, which will reduce the injection efficiency and increase the pain of the patient. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a fall-off preventing syringe and injection needle which can prevent the needle and needle tube of the syringe from falling off. [0004] The solution to the technical problem of the present invention is...
