[0005] 3. Discarded needles have not been sorted, but are put together with medical waste (such as cotton balls, gauze, etc.)
[0012] As mentioned above, it uses elasticity to push out the tube body so that the needle can be covered by the tube body. It is quite convenient in use, but in practice, it may happen that the injection process has not been completed, and the tube body may be damaged due to a malfunction. Early ejection, which also causes unnecessary pain to the patient

Embodiment Construction

[0032] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0033] Relevant detailed description and technical contents of the present invention are as follows with regard to coordinating accompanying drawings now:

[0034] see Figure 1A , Figure 1B ~ Figure 3 As shown, it is the three-dimensional appearance, structural decomposition and cross-sectional structure diagram of the present invention, as shown in the figure: the present invention is a syringe for preventing accidental injury, including an injection syringe 10, a protective sleeve 20 and a positioning buckle clip 30, wherein the injection syringe 10 has a cylinder body 11, a push rod 12 that is in close contact with and slides into the inside of the cylinder body 11 and is located on the side of the cylinder body 11 away from the push rod 12 and communicates with the cylinder body 11 An injection head 13 of.

Abstract

The invention discloses an accidental-injury-preventing injector. The accidental-injury-preventing injector comprises a protective sleeve. A cylinder is sleeved with the protective sleeve, the protective sleeve has axial-rotation and sliding freedom degrees, and comprises an annular protruding fixing piece with a clamping positioning section and a releasing positioning section and a positioning buckle which is connected with the cylinder and comprises a pressing part and a clamping part, wherein the clamping part positions and clamps the annular protruding fixing piece, when the protective sleeve rotates to allow the releasing positioning section to correspond to the positioning buckle and presses the pressing part, the clamping part swings to an operating position from an initial position accordingly, and the annular protruding fixing piece breaks away from positioning and clamping of the clamping part. In this way, a user needs to meet the conditions of two kinds of movement at the same time, the protective sleeve can move outwards to cover the injector, and the incorrect movement problem caused when the pressing part is incorrectly touched is effectively solved.

Description

technical field [0001] The invention relates to a syringe preventing accidental injury, in particular to an operation structure of the syringe preventing accidental injury. Background technique [0002] Injection syringes are frequently used by medical personnel. Needle stick accidents often occur when many medical personnel use injection syringes. The occurrences can be roughly summarized as follows: [0003] 1. Medical personnel are prone to needle sticks before they are discarded into the exclusive waste bin after use; [0004] 2. Use needles when the patient is restless; [0005] 3. Discarded needles have not been sorted, but are put together with medical waste (such as cotton balls, gauze, etc.). [0006] In order to solve the endless needle sticking problems, there are currently many design directions for safety needles. For example, some needles can be retracted into the space originally filled with medicines through complicated operations. However, retractable saf...
