As shown in the first to seventh embodiments, a perspective view, a perspective exploded view, a perspective view of the use operation, and a perspective view of the internal structure of the protection kit are shown in the first embodiment. As shown in the figure, the injection syringe safety protection set of the present embodiment includes An injection syringe 10, a protective cover unit 20 and a pivot unit 30 disposed on the front end of the injection syringe 10.

The syringe 10 has a large diameter tube 11, a small diameter tube 12, a push rod 13 and a needle holder 14, and a needle 141 is disposed on the needle holder.

The protective cover unit 20 has a sleeve 21, a sleeve portion 211 disposed at the proximal end of the sleeve 21, a flange 213 spanning between the sleeve 21 and the sleeve portion 211, and a sleeve 211 disposed at the sleeve portion 211. The upper pivot hole 212, a set of needle slots 22 and a stop member 221, 222 disposed in the trocar slot 22.

The pivot unit 30 is disposed on a fixed pivot portion 34. The pivot unit 30 is disposed in a vertical relationship with the small diameter tube 12 of the injection syringe 10. The upper end of the pivot unit 30 is formed into a tapered head 31 and defines a slit 32. The middle portion is formed into a thin neck portion 33 to pivot the pivot hole 212 of the cover unit 20.

The protective cover unit 20 has a hollow sleeve 21 with a horizontal side opening, and the sleeve 21 A needle groove 22 is disposed on the ferrule groove 22, and the ferrule groove 22 is a longitudinal cleavage structure closed at one end, and the groove direction of the trocar groove 22 can be engaged with the needle 141 to be locked in use relationship.

The trocar groove 22 is provided with two stoppers 221 and 222 in the middle portion thereof, and the stoppers 221 and 222 in the embodiment are respectively shown in the fifth to seventh embodiments, and the slits are respectively from the notches of the ferrule groove 22. It extends obliquely inwardly to the other side and stops at the intermediate section of the trocar groove 22.

The sleeve 21 has a extending portion 210 bent at one end thereof and a set of connecting portions 211 thereon, and a pivot hole 212 is formed in the sleeve portion 211. The size of the pivot hole 212 is smaller than the tapered head 31 of the pivot unit 30. The outer diameter is elastically pressed into the pivot unit 30 and is centered on the neck 33 of the pivot unit 30.

The other side of the side opening of the sleeve 21 is provided with a flange 213 for horizontal movement of the finger during operation.

A positioning bump 214 (see FIGS. 6 and 7) is disposed on each side of the pivot hole 212 under the front end extension portion of the sleeve 21, and can be locked with a positioning surface 341, 342 on both sides of the fixed pivot portion 34, respectively. .

After the protective cover unit 20 of the injection syringe 10 is pressed into the neck portion 33 of the pivot unit 30 by the pivot hole 212, the sleeve 21 of the protective cover unit 20 can be pivoted as shown in FIGS. 3 and 5. 30 is pivoted to the needle end of the needle holder 14, and the needle 141 is inserted into the inside of the sleeve 21 through one side opening of the trocar groove 22, and is hidden inside the protective cover unit 20.

Further, as shown in FIGS. 3 and 5, it is a schematic view showing the state of use of the protection kit and the needle in the first embodiment of the present invention, and the sleeve 21 of the protective cover unit 20 is pivoted toward the needle end of the needle holder 14. During the rotation, the needle 141 will first push the stoppers 221, 222, and will be inserted into the sleeve 21 corresponding to the position of the trocar groove 22, and the sleeve 21 will be completely covered as shown in Fig. 5. The needle 141 is external, and the tip end portion of the needle 141 is concealed in the sleeve 21 by being completely covered by the sleeve 21, and does not expose the outside.

The stoppers 221 and 222 stand on the elastic property of the material after the needle 141 passes. That is, the original shape is restored, and the protective cover unit 20 is stopped in the trocar groove 22 by the stoppers 221 and 222 which are returned to the original shape, so that the needle 141 is prevented from coming out of the sleeve 21 by the trocar groove 22.

Furthermore, as shown in Figures 3 to 5, after the medical staff pulls out the injection syringe 10 from the patient, the medical staff uses the index finger to abut the flange 213 on the side of the sleeve 21 and then to the left in a horizontal manner. The flange 213 of the sleeve 21 is swung to pivot the sleeve 21 horizontally with the pivot unit 30 as an axis, and the needle 141 is completely covered and hidden in the sleeve 21 through the trocar groove 22 (as shown in Fig. 5). As shown in the figure), the needle 141 is prevented from coming out of the sleeve 21 again by the stoppers 221, 222, so as to prevent the needle 141 from being taken out again, and the medical staff can remove the syringe from the patient. At 10 o'clock, away from the tip of the needle 141, to avoid the chance of infection caused by accidental stabbing of medical personnel due to improper application.

Referring to FIGS. 8-10, the construction of the injection syringe 10 of the second embodiment of the present invention is substantially the same as that of the injection syringe 10 of the first embodiment, and is labeled with the same component symbols for mutual control. For the sake of simplicity, the relevant description is omitted.

The difference between the embodiment and the first embodiment is that the small diameter tube 12 of the injection syringe 10 of the first embodiment is directly provided with the pivot unit 30, and the embodiment is for the old injection syringe 10A. It can also be fully applied, and a connecting sleeve 40 is set on the small diameter tube 12A of the injection syringe 10A. Since the capacity of the injection syringe is from 1 to 50 cc, the small diameter tube is changed regardless of the size of the syringe. The outer diameter of the 12A is the same (to facilitate the fixing of the needle seat), the inner diameter of the connecting sleeve 40 and the outer diameter of the small diameter tube 12A are substantially matched, so that the old injection syringe 10A is small diameter tube 12A. The kit is connected to the sleeve member 40, and the pivot unit 30 is implanted in the connecting sleeve member 40 to achieve the same effect as the first embodiment.

In the second embodiment of the present invention, the needle 141 is completely covered and hidden in the sleeve 21A, and the stopper 221A, 222A is used to prevent the needle 141 from coming out of the sleeve 21A again, so as to prevent the needle 141 from being taken out again. Opportunity, therefore, the risk of contamination of the medical staff due to needle sticking caused by the exposure of the needle needle 141 is prevented, and the used needle 141 is indeed hidden and fixed to the trocar. The inside of the groove 22A cannot be taken out again, so as to prevent it from being reused.

Referring to FIGS. 11-16, the construction of the injection syringe 10 of the third embodiment of the present invention is substantially the same as that of the first embodiment, and the same component symbols are used for mutual control. For the sake of simplicity, The relevant instructions are omitted.
