This first embodiment has the following two usage modes:

[a]One-handed plug-in mode: Due to the busy work of the medical staff, it is possible to use only one hand to remove the needle from the needle cylinder (the other hand may read the relevant medical information), so the syringe of the injection device 90 can be held by one hand. a portion 91 (used waste), the needle head 92 is first inserted into the insertion hole 121, and then inserted between the pair of first bonding portions 142, so that the pair of first bonding portions 142 are to be clamped The holding position P1 is expanded to change to the holding position P2, and the needle connecting end piece 921 is clamped (strongly). (Because the first seat portion 10 has a see-through structure, the needle connecting end piece 921 can be visually observed. After being gripped by the pair of first bonding portions 142; and then withdrawing the syringe portion 91, the syringe coupling end member 911 and the needle coupling end member 921 are separated from each other, thereby achieving the operation of removing the needle (refer to the second C and Third C)), pressing the pair of first pressing portions 141 (see FIG. 1B), the first bonding portion 142 can be pushed away from the clamping position P2 through the pair of first linking mechanisms 143. Up to the release position P3, the needle head 92 falls into the needle accommodation space 21.

[b] One-handed plug-and-pull mode: This mode of operation is mostly the same as the one-hand plug-and-play mode described above, the only difference being that when the needle head 92 is inserted and the pair of first engaging portions 142 (strong) After being clamped, the syringe portion 91 is first rotated to rotate the syringe coupling end member 911 and the needle coupling end member 921 (relatively loosened and disengaged), and then the needle cylinder portion 91 is withdrawn, and the same is achieved. Hand removal of the needle.

When it is assumed that the needle head 92 is not clamped during the extraction process, it may accidentally fly out during the plucking process and hurt the user. Therefore, the second line of defense against the needle flying out may be added in this case, which is a preventive pop-up. The device 12A (see FIGS. 4, 5, 6 and 7A) is substantially circular and has a fixing portion 1211, an elastic portion 1212 and an opening portion 1213 in a direction from the circumference toward the center of the circle. Wherein: the fixing portion 1211 can be a circular plate and fixed (the present invention is a screw lock, and can also be any means of sticking and can be fixed) on the partition plate 12; the elastic portion 1212 includes a plurality of Each of the elastic pieces extends from the fixing portion 1211 toward the opening portion 1213, and is inclined from the partition plate 12 toward the first space 111, and is substantially circularly distributed; the opening portion 1213 It is located at the end of the elastic portion 1212 and is switchable between a relative closed position X1 and a relative open position X2 (see Figure 7B).

The ejection preventing device 12A exhibits an action of pushing the needle connecting end piece 921 And passing through the opening portion 1213 (refer to FIG. 7B, the opening portion 1213 is changed from the relative closed position X1 to the relative open position X2) → the needle connecting end piece 921 is inserted and clamped to the pair first Between the bonding portions 142 → the elastic portion 1212 rebounds → the opening portion 1213 is retracted above the needle connecting end piece 921 (refer to FIG. 7C) → the syringe connecting end piece 911 pulls out the insertion hole 121 → The elastic portion 1212 rebounds again. The opening portion 1213 returns to the pair of closed positions X1. The needle connecting end piece 921 is pressed by the opening portion 1213 so as not to fly out of the insertion hole 121 (see FIG. 7D).

Referring to the eighth embodiment, the second embodiment of the present invention differs from the first embodiment only in that the first elastic member 14D is sleeved on the first rod member 14C and supported on the first rod member 14C. The first pressing portion 141 is between the outer surface of the first seat portion 10; and is changeable between an uncompressed position P4 (see the eighth and twelfth figures) and a compressed position P5 (see the ninth figure). When the uncompressed position P4 is located, the pair of first abutting portions 142 is kept at a distance D1 from which the needle head 92 is extended; thereby, the pair of first linking mechanisms 143 are provided for the first pair When the pressing portion 141 is pressed into the first space 111, the pair of first bonding portions 142 can be forced to move relative to each other, and moved from the position P1 to be clamped (see FIG. 8) to the clamping position P2. (refer to the ninth figure); and further comprising: a second seat portion 30 having a second annular wall 31, a pair of second openings 32 and a syringe clamping portion 33; the second annular wall 31 Forming a second space 311 and having a limiting member 312; the pair of second openings 32 for the syringe clamping portion 33 to penetrate the second space 311 and positioning; the pair of cylinders are pinched The 33 series has a pair of second pressing portions 331, a pair of second bonding portions 332, and a pair of second linking mechanisms 333. The pair of second pressing portions 331 are exposed outside the second opening 32. When the pair of second pressing portions 331 are pressed into the second space 311, the interlocking mechanism 333 can force the pair of second bonding portions 332 to move inward relative to each other; the first seat portion 10 corresponds to the second seat portion The method further includes: a rotary positioning wall portion 16 extending upward from the partition plate 12, and an axial limiting member 161 corresponding to the limiting member 312; the axial limiting member 161 and the limiting portion 312 is for The first and second seat portions 10 and 30 are coaxially rotated relative to each other (see the tenth and eleventh views), and are restricted from being relatively detachable; thereby, when the pair of first pressing portions 141 and the pair of second pressing portions The portion 331 is pressed; the pair of first bonding portions 142 and the pair of second bonding portions 332 both have a clamping function (see FIG. 9); and, when the pair of first pressing portions 141 and the pair of second pressing portions When the portion 331 is not pressed, the pair of first bonding portions 142 and the pair of second bonding portions 332 both have a releasing function.

Each of the second linking mechanisms 333 includes a second lever member 33A located in the second space 311 and extending corresponding to the second opening 32. The second pressing portion 331 is coupled to the second opening portion 331 The second rod member 33A is extended to the end of the second opening 32; the second engaging portion 332 is coupled to the end of the second rod member 33A located in the second space 311; a second elastic member 33B is The second rod member 33A is sleeved between the second pressing portion 331 and the outer surface of the second seat portion 30; and can be in the uncompressed position P4 (refer to the eighth and twelfth figures) Switching between the compression position P5 (see FIG. 9), when the uncompressed position P4 is located, the pair of second bonding portions 332 is maintained at a distance D2 between the pair of the needle portions 91.

Referring to the eighth embodiment, the second embodiment is used by inserting the needle head 92 of the injection device 90 into the insertion hole 121 of the partition 12.

Referring to the ninth figure, the first and second seat portions 10 and 30 are simultaneously held, and the pair of needle clamping portions 14 and the pair of syringe clamping portions 33 are simultaneously pressed (refer to the tenth figure, one hand holding) The first seat portion 10 presses the needle crimping portion 14 and holds the second seat portion 30 by another hand and presses the syringe crimping portion 33, which is achieved. At this time, the second bonding portion 333 of the pair of syringe clamping portions 33 is clamped (the second elastic member 33B is pressed by the outer surfaces of the second pressing portion 331 and the second seat portion 30). Department 91. At the same time, the first bonding portion 142 of the needle clamping portion 14 is clamped (the first elastic member 14C is pressed by the first pressing portion 141 and the outer surface of the first seat portion 10). The needle connecting end piece 921.

Referring to the eleventh figure, the first and second seat portions 10 and 30 are rotated relative to each other, and the needle coupling end piece 921 and the syringe coupling end piece 911 are relatively rotated to be loosened.

Referring to the twelfth figure, since the syringe coupling end piece 911 and the needle coupling end piece 921 are loosened, in principle, the pair of needle clamping portions 14 are released at this time (from the clamping position P2 Change to the position to be clamped P1). The pair of second elastic members 14B pushes the pair of first abutting portions 142, and the needle head portion 92 should fall to the needle receiving space 21. This achieves the effect of "spinning and replacing".

If the needle head 92 does not fall off due to a certain factor (for example, the card is too deep), the first and the second seat portions 10 and 30 can be controlled to rotate relative to each other after the original clamping position P1, and then the first, The second seat portions 10 and 30 are relatively coaxially movable (may also be coaxially retracted, and the axial limiting member 161 and the limiting member 312 can limit the first, the second seat portions 10 and 30 are not completely The needle portion 91 and the needle head 92 are completely detachable (see the thirteenth diagram).

Referring to the fifteenth and sixteenth embodiments, a third embodiment of the present invention differs from the second embodiment only in that each of the first pressing portions 141 has a diamond-shaped elastic structure and has two or two Each of the four elastic pieces has a first height C1; each of the first bonding portions 142 has an elastic clip structure and has a second height C2, which is smaller than The first height C1; the first linking mechanism 143 is substantially pivotally connected, and the first bonding portion 142 is bent and coupled to the corresponding pair of elastic pieces to form an enclosed area W (see the seventeenth Each of the second pressing portions 331 has a diamond-shaped elastic structure and has two elastic pieces opposite to each other; and each of the elastic pieces has a first height C1; each of the second bonding portions 332 An elastic clip structure has a second height C2 that is smaller than the first height C1. Each of the second linkages 333 has a pivotal structure for the second bonding portion 332. The surrounding area W is formed by bending and joining the corresponding pair of elastic pieces.

Referring to FIGS. 17A and 17B, when the pair of first pressing portions 141 are respectively loosened and pressed, the pair of first engaging portions 142 are interlocked by the pair of first linking mechanisms 143, respectively, and the releasing function is respectively generated. With the clamping function.

Similarly, when the pair of second pressing portions 331 are respectively loosened and pressed, the pair of second bonding portions 332 are interlocked by the pair of second linking mechanisms 333 to respectively generate a releasing function and a clamping function.

That is, in the process of plucking the needle head 92, the hand does not touch the hand. The needle head 92 can reduce the accident that the needle flies out and hurts people due to inadvertent movement (for example, the needle head 92 flies out due to loose hands).

In addition, when the syringe coupling end piece 911 and the needle coupling end piece 921 are separated from each other, even if a certain factor causes the needle head 92 not to fall from the pair of first bonding portions 142 (for example, jam), the present When the needle head 92 is inserted, the needle head 92 that has not been dropped last time can still be poked, and the normal use can be ensured without failure.

The advantages and functions of this creation can be summarized as follows:

[1] The needle can be removed with one hand. When the pair of first engaging portions of the pair of needle clamping portions are substantially in close contact, the needle head can be opened and the pair can be inserted by inserting the needle head between the pair of first bonding portions. The first bonding part is clamped. At this time, as long as the cylinder is unscrewed (if it is rotated, it can be loosened and easily removed), the needle head is still clamped by the pair of first bonding parts to achieve the needle removal operation. . Therefore, the needle can be removed with one hand.

[2] It is quite convenient to complete the needle retraction in a coherent motion. In this creation, the needle connecting end piece is inserted into the insertion hole of the partition plate, and then the first and second seat parts are simultaneously pressed, and then the first and second seat parts are controlled to rotate relative to each other, and then the needle is removed. The entire needle-removing operation is easy and convenient. Therefore, it is quite convenient to complete the needle retracting in a continuous motion.

[3] No need to touch the needle for high safety. In the process of retracting the needle with one hand, the needle head is held by the needle clamping portion, and the hand does not need to touch the needle. Even if the needle is retracted by both hands, the needle portion is also clamped by the needle clamping portion. The hand still does not need to touch the needle, the whole process of retracting the needle, the hand does not need to touch the needle at all, effectively reducing the risk of being accidentally pinched by the needle. Therefore, it is not necessary to touch the needle with high safety.

[4] There is a second line of defense against needle flying. The invention is provided with an anti-ejection device under the partition plate. When the needle head is inserted into the first opening to be positioned, the ejecting device is prevented from being pressed over the needle connecting end piece, thereby even if the needle connecting end piece is not clamped during the removal of the needle. When it is pulled out, when the needle is pulled out, the needle connecting end piece is still pressed under the ejection preventing device, and there is almost no flying out. Therefore, there is a second line of defense against needle flying.

The above is only a detailed description of the present invention by way of a preferred embodiment, and any modifications and variations of the embodiments are possible without departing from the spirit and scope of the present invention.
