17 Preferably, with reference to Fig. 5, the safety needle cap has two 18 holding segments (20A) longitudinally formed on and protruding from the open 19 end of the body (1 OA). With reference to Fig. 10, the extending stem (21 E) is formed on the external surface of the body (10E) between the open end and the 21 closed end and has a free end (211E). Preferably, with further reference to Figs. 9 22 and 10, the extending stem (21D, 21E) has a connecting panel (23D, 23E) 23 transversally formed on the extending stem (21D, 21E) at an end opposite to the 24 free end (211D, 211E) and connected to the body (1OD, 1OE) to prevent the 1 extending stem (21D, 21 E) from interfering with the large size syringe needle 2 (70).
3 The pulling tab (22, 22A, 22B, 22C, 22D, 22E) is formed on the free end 4 (211, 211A, 211B, 211C, 211D, 211E) of the extending stem (21, 21A, 21B, 21C, 21D, 21 E) to allow the extending stem (21, 21A, 21B, 21C, 21D, 21 E) to be 6 pulled easily.
7 In use, with reference to Figs. 1, 2, 6, 7, 9 and 10, the needle (40, 50, 60, 8 70) is removed from the safety needle cap in accordance with the present 9 invention, one hand holds the pulling tab (22, 22A, 22B, 22C, 22D, 22E) of the holding segment (20, 20A, 20B, 20C, 20D, 20E) and the other hand pulls the 11 needle (40, 50, 60, 70) out of the body (10, 1 OA, 10B, 10C, IOD, 1OE).
During 12 removal, direct contact between the hand that holds the pulling tab (22, 22A, 13 22B, 22C, 22D, 22E) and the needle (40, 50, 60, 70) is prevented by the 14 extending stern (21, 21A, 21B, 21C, 21D, 21E). In other words, the hand that holds the pulling tab (22, 22A, 22B, 22C, 22D, 22E) is kept away from the tip of 16 the needle (40, 50, 60, 70). Then, the hand that holds the pulling tab (22, 22A, 17 22B, 22C, 22D, 22E) or the free end of the extending stem (21, 21A, 21B, 21C, 18 21D, 21E) is prevented from injury by the extending stem (21, 21A, 21B, 21C, 19 21D, 21E) even if either hand is accidentally knocked or jogged when removing or replacing the needle (40, 50, 60, 70).
21 After use, the needle (40, 50, 60, 70) is replaced in the needle cap and the 22 tip of the needle (40) is guided into the chamber of the body (10, 1 OA,1 OB, I OC, 23 1OD, 1OE) by the extending stem (21, 21A, 21B, 21C, 21D, 21E) of the holding 24 segment (20, 20A, 20B, 20C, 20D, 20E). Accordingly, the hand that holds the 1 pulling tab (22, 22A, 22B, 22C, 22D, 22E) or the free end of the extending stem 2 (21, 21A, 21B, 21C, 21D, 21E) is kept from contacting the tip of the needle (40, 3 50, 60, 70). After the used needle (40, 50, 60) is mounted in the chamber of the 4 body (10,1 OA, l OB, I OC), the body (10,1 OA, l OB,1 OC) can be bent as shown in Figs. 4 and 8 by the bending segment (11,11A,11B,11C) to bend the needle (40, 6 50, 60) in the chamber of the body (10, 10A, 10B, 10C). Thus, the used, bent 7 needle (40, 50, 60) is prevented from being reused.
8 The safety needle cap in accordance with the present invention can 9 prevent the hand that holds the pulling tab (22, 22A, 22B, 22C, 22D, 22E) or the free end of the extending stem (21, 21A, 21B, 21C, 21D, 21E) from being 11 injured by the tip of the needle (40, 50, 60, 70) and the bending segment (11,11A, 12 11B, 11C) of the body (10, 10A, 10B, 1OC) can provide a bending effect to the 13 needle (40, 50, 60) to prevent the used needles (40, 50, 60) from being reused.
14 Furthermore, the safety needle cap in the referenced patent application can be bent once to allow the body (10, 1OA, l OB, IOC) bending closely to 180 16 degrees and the body in the document D2 needs to bend at several times and this 17 is different in operation. In addition, the at least one holding segment (20, 20A, 18 20B, 20C, 20D, 20E) is formed with the body (10,1OA, IOB, 1 OC, 1OD, IOE) as 19 a single piece and one hand of the user can hold the pulling tab (22, 22A, 22B, 22C, 22D, 22E) to prevent the safety needle cap in accordance with the present 21 invention separating from the needle (40, 50, 60, 70) when bending the safety 22 needle cap and also can prevent the tip of the needle (40, 50, 60, 70) from 23 injuring the users and prevent the liquid from flowing out of the safety needle 24 cap. Additionally, the user also can hold the at least one holding segment (20, 1 20A, 20B, 20C, 20D, 20E) of the safety needle cap by one of the hands and push 2 and press the body (10, 10A, IOB, IOC, 1OD, 1OE) on a wall or a table to bend 3 the body (10, 10A, IOB, IOC, IOD, 10E) of the safety needle cap without using 4 two hands at the same time.
Even though numerous characteristics and advantages of the present 6 invention have been set forth in the foregoing description, together with details 7 of the structure and function of the invention, the disclosure is illustrative only, 8 and changes may be made in detail, especially in matters of shape, size, and 9 arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended 11 claims are expressed.
