AI Technical Summary
Current medical syringes pose a risk of needlestick injuries during needle removal, particularly for medical personnel, due to their sharp nature and the potential for cross-infection from blood or body fluids contained in the needle cavity.
A safety syringe design featuring a spray cylinder with a needle sliding seat and push plate mechanism, where the needle is covered by a transparent hard plastic seat with notches and bumps, allowing safe and easy removal by pressing the push plate to slide the needle out.
The design effectively prevents needlestick injuries by enabling safe and quick removal of the needle, enhancing user safety and reducing the risk of cross-infection.

Abstract
Description
Technical area
[0001] The utility model relates to the technical field of a safety syringe, specifically to a safety syringe. Background technology
[0002] Disposable syringes are currently one of the most widely used instruments in medical facilities and the most widely used medical supplies in nursing. However, syringe needles are sharp, and puncture wounds often occur when they are used or handled by caregivers, for example, when the needle is removed and placed in the sharps container.
[0003] The prevention and treatment of needlestick injuries remains a key focus of nosocomial infection management, particularly post-use syringes, which may contain the patient's blood or body fluids in the needle cavity and pose a risk of cross-infection to medical personnel following an accidental injury. Therefore, there is a need to improve the currently widely used disposable syringes to prevent needlestick injuries during needle removal. Content of the utility model
[0004] The utility model discloses a technical problem to be solved, namely to overcome the deficiencies of the above-mentioned subject and to provide a safety syringe.
[0005] To solve the technical problem, the utility model discloses a safety syringe comprising a syringe barrel and a needle. The front end of the syringe barrel is provided with a protrusion and a needle slide seat. The needle slide seat covers the front end of the syringe barrel and slides into place. The needle slide seat is provided with a notch, the protrusion is positioned in the notch, and the limiting slide fits into it. A push plate is provided at the rear end of the needle slide seat, and the front end of the needle slide seat can slide the rear end of the needle.
[0006] As an improvement, the number of bumps is two, arranged back to back and firmly connected to the syringe barrel.
[0007] As an improvement, the needle slide seat is made of transparent hard plastic.
[0008] The utility model discloses an advantage over the prior art in that when removing the needle, one hand holds the rear end of the syringe barrel, and the finger of the other hand virtually clamps the syringe barrel and directly pushes the push plate, and the needle pusher seat moves forward along the bump, pushing the needle until it falls off, and the push plate simultaneously serves as a finger lock.
[0009] The safety syringe allows for quick needle removal by moving the fingers away from the needle, effectively preventing needle sticks. It is easy to use and has high practical and promotional value. Description with drawings Fig. is a schematic structural diagram of a utility model safety syringe. Fig. is a side view of a safety syringe of the present utility model. Fig. is a schematic structural representation of a utility model safety syringe with the needle pressure seat removed. Fig. is a structural schematic diagram 1 of a needle pressure seat of a safety syringe of the utility model. Fig. is a second structural schematic diagram of a needle pressure seat of a safety syringe of the utility model.
[0010] As shown in the figure: 1. Syringe barrel, 2. Needle, 3. Bump, 4. Needle pusher seat, 5. Notch, 6. Pusher plate. The specific embodiment
[0011] The safety syringe of the utility model is described in more detail below in connection with the attached drawings.
[0012] In connection with the Fig., a safety syringe comprising a syringe barrel 1 and a needle 2. The front end of the syringe barrel 1 is provided with a bump 3 and a needle sliding seat 4, the needle sliding seat 4 covering the front end of the syringe barrel 1 and sliding into place. The needle sliding seat 4 is provided with a notch 5, the bump 3 is positioned in the notch 5, and the limiting slide fits into it. A pushing plate 6 is provided at the rear end of the needle sliding seat 4, and the front end of the needle sliding seat 4 can slide the rear end of the needle 2.
[0013] The number of bumps 3 is two, which are arranged back to back and firmly connected to the syringe barrel 1.
[0014] The needle slide seat 4 is made of transparent hard plastic.
[0015] In the specific implementation of the utility model, when the needle is to be removed, one hand holds the rear end of the syringe barrel 1, and the finger of the other hand virtually clamps the syringe barrel 1 and directly pushes the push plate 6, and the needle pusher seat 4 moves forward along the bump 3, pushes the needle 2 until it falls off, and the push plate 6 simultaneously serves as a finger lock.
[0016] The utility model and its embodiments have been described above. This description is not limiting. What is shown in the drawings is only one embodiment of the utility model, and the actual structure is not limited to it. In short, if an average person skilled in the art can be inspired by it and, without deviating from the creative purpose of the utility model, design a structural method and embodiment similar to the technical solution without creativity, they all fall under the protection of the utility model.
