During the sliding of the guide portion 502 along the puncture guide surface 105, the puncture guide surface 105 applies an urging force to the guide portion 502 that urges the guide portion 502 to move along the bar-shaped groove 402 in a direction away from the one end 102 of the second chassis 100 (see fig. 16A in cooperation). During the movement of the guide portion 502 along the bar-shaped groove 402 in a direction away from the end 102 of the second base 100, the guide portion 502 drives the piercing member 500 to move in a direction approaching the fixing portion 403 relative to the second accommodating chamber 401 of the mounting base 400, so that the lancet 501 of the piercing member 500 pierces the small-sized high-pressure gas bottle 600 fixed on the fixing portion 403 (see fig. 16B and 16C in cooperation).

Wherein the guide portion 502 slides down along the puncture guiding surface 105 from an initial position C of the puncture guiding surface 105 to a maximum puncture position D and continues to slide down to an end position E of the puncture guiding surface 105 (see fig. 17 for cooperation).

When the guide portion 502 is slid down along the puncture guide surface 105 from the initial position C of the puncture guide surface 105 to the maximum puncture position D, the puncture member 500 moves to the maximum position in a direction approaching the fixing portion 403 with respect to the second accommodation chamber 401 of the mount 400, and at this time, the puncture needle 501 penetrates the small-sized high-pressure gas bottle 600 to the deepest depth.

When the guide portion 502 slides down along the puncture guide surface 105 from the maximum puncture position D of the puncture guide surface 105 to the end position E, the puncture member 500 moves away from the fixing portion 403 with respect to the second accommodation chamber 401 of the mount 400, and after passing the end position E, the guide portion 502 starts to move leftward along the bar-shaped groove 402 until returning to the leftmost end of the bar-shaped groove 402.

The guide portion 502 slides down from the end position E of the puncture guide surface 105 to the lock groove 103, and the lock groove 103 can lock the guide portion 502.

After the rubber stopper of the mouth of the small-sized high-pressure gas bottle 600 is pierced, the high-pressure gas in the small-sized high-pressure gas bottle 600 flows into the lancet subspace 410 and the sliding subspace 409 of the third space 407 of the second accommodating chamber 401 (see fig. 18 for cooperation). Specifically, in the lancet subspace 410 of the third space 407, the high pressure gas flows into the sliding subspace 409 through the recess 505 of the lancet 501.

In the sliding subspace 409, the high-pressure gas flows into the fluid chamber 504 of the piercing member body 503 through the passage groove 511, and flows into the tracheal joint 412.

When the guide 502 slides into the locking groove 103 (see fig. 19A, 19B and 19C, for example), as long as the small-sized high-pressure gas bottle 600 contains high-pressure gas, the high-pressure gas flowing out or ejected from the small-sized high-pressure gas bottle 600 pushes the lancet body 503 and the lancet 501 in a direction approaching the one end 102 of the second base 100, so that the lancet body 503 and the lancet 501 have a movement in a direction approaching the one end 102 of the second base 100, and further the guide 502 moves further downward along the movement of the locking groove 103 in a direction approaching the one end 102 of the second base 100, thereby locking the guide 502 by the locking groove 103 (see fig. 20A, 20B and 20C, for example). This prevents the operator from opening the pressure lever 200 by mistake, avoiding danger. At this time, the pressing lever 200 is in the second position.

When the high pressure gas in the small-sized high pressure gas bottle 600 is released, the piercing member body 503 and the lancet 501 are not pushed by the high pressure gas so that the guide 502 can move upward along the locking groove 103.

Pushing up on the second end 205 of the plunger 200, the plunger 200 rotates in a second rotational direction (i.e., the direction of arrow B in fig. 20A and 20B) about the one end 102 of the second base 100 from the second position. The pressing bar 200 moves upward along the locking groove 103 and upward along the puncture guiding surface 105 by the guide 502 first by the link 300, and finally moves away from the upper edge 104 of the second base 100.

When the pressing lever 200 is rotated back to the first position in the second rotation direction (i.e., the direction of arrow B in fig. 20A and 20B), the fixing portion 403 of the mounting seat 400 is located above the first receiving chamber 101 of the second base 100, and at this time, the small high pressure gas bottle 600 having released the high pressure gas is already located above the first receiving chamber 101 of the second base 100, the small high pressure gas bottle 600 having released the high pressure gas can be detached, and then a new small high pressure gas bottle 600 can be replaced.

In addition to the above embodiment, the guide portion 502 is directly rotated to a state of being in contact with the puncture guiding surface 105 of the second chassis 100 (see fig. 15A and 15B for cooperation), the guide portion 502 may be rotated to a state of being in contact with the upper edge 104 of the second chassis 100 (see fig. 21 for cooperation) and then moved rightward along the upper edge 104 of the second chassis 100 to a state of being in contact with the puncture guiding surface 105 (see fig. 15A and 15B for cooperation). During this rightward movement, the guide 502 moves the lancing member 500 a small distance relative to the second housing chamber 401 in a direction approaching the fixing portion 403, but this small distance is insufficient to cause the lancet 501 to lance the small, high pressure gas cylinder 600 fixed to the fixing portion 403.

The operational procedure of the embodiment of fig. 22 differs from the operational procedure of the embodiment of fig. 4 as follows:

depressing the plunger 200 rotates the plunger 200 in the first rotational direction (i.e., the direction of arrow a in fig. 26, 27 and 28), the plunger 200 directly rotates the guide 502 directly to a state of contact with the upper edge 114 of the support 111 of the holder 107 of the second chassis 100 or the puncture guide surface 105 to slide along the puncture guide surface 105, and finally slides the guide 502 into the locking groove 103 (see fig. 29 for cooperation).

When the high pressure gas in the small-sized high pressure gas bottle 600 is released, the second end 205 of the pressing lever 200 is pushed upward, and the pressing lever 200 is rotated in a second rotation direction (i.e., the direction of arrow B in fig. 29 and 30) around the one end 102 of the second base 100 from the second position. The pressing lever 200 is rotated in the second rotation direction (i.e., the direction of arrow B in fig. 29 and 30) by driving the guide 502.

After the guide 502 is disengaged from the locking groove 103, the guide 502 pushes the holder 107 to rotate about the shaft 108 in the second rotation direction (i.e., the direction of arrow B in fig. 29 and 30) so that the holder 107 gives room for the rotation of the guide 502, and after the guide 502 passes over the holder 107, the holder 107 rotates about the shaft 108 in the second rotation direction (i.e., the direction of arrow B in fig. 29 and 30) under the own weight force back to the state of fig. 26.

The operation of the portable needleless injection system of an embodiment of the present invention is described below with reference to the accompanying drawings.

In use, the cover 9000 is opened.

The first gas pressure gauge 4001 and the second gas pressure gauge 4002 are observed, and the pressure regulating valve 5000 is rotated until the pressure value displayed by the second gas pressure gauge 4002 is the target value.

The injection device 8000 and the second tube 8001 are removed from the second compartment 1002.

The other end of the second tube 8001 is mounted to the joint 4003 and the liquid output is directed to the skin.

The switch on the solenoid valve 6000 is directly operated so that the injection device 8000 acquires the high-pressure gas of which the pressure value is the target value. Alternatively, the switch on the injection device 8000 is operated, and the switch on the solenoid valve 6000 is controlled by the controller 7000 in a wireless communication manner so that the injection device 8000 acquires the high-pressure gas of which the pressure value is the target value.

After the end of use, the other end of the second conduit 8001 is removed from the joint 4003, and then the injection device 8000 and the second conduit 8001 are housed in the second magazine 1002.

Finally, the cover 9000 is closed and lifted by the handle 1003.
