[0002] A small high-pressure gas cylinder is a device for storing high-pressure gas and is widely used in the automotive, chemical, fire protection, medical, and food industries. One of its functions is to provide a stable driving force to other devices by releasing high-pressure gas, such as providing a driving force to a needle-free injector.

[0003] When in use, it is necessary to connect the puncturing device to a small high-pressure gas cylinder and an injection device (also called an injection gun), and puncture the small high-pressure gas cylinder (i.e., the gas source) with the puncturing device to release the high-pressure gas in the small high-pressure gas cylinder to the injection device.

Specific design features disclosed in this invention (including, for example, specific dimensions, orientations, positions, and shapes) will be determined in part by the specific environment in which they are intended for application and use.

[0095] Throughout these figures, the same reference numerals denote the same or equivalent parts of the invention. Detailed Implementation

[0096] Reference will now be made in detail to various embodiments of the invention, examples of which are presented in the accompanying drawings and described below. Although the invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the invention to these exemplary embodiments. Rather, the invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other embodiments that may be included within the spirit of the invention and the scope defined by the appended claims.

[0097] When a component is described as being "above" or "on top of" another component, that component may be in contact with the other component, or there may be an intermediate component present.

[0098] The following is combined with Figures 1 to 3 A portable needle-free injection system according to an embodiment of the present invention will be described.

[0099] like Figures 1 to 3 As shown, the portable needle-free injection system of the present invention includes: a first base 1000, a puncture device 2000, an air source, a first pipeline 4000, a pressure regulating valve 5000, a solenoid valve 6000, a controller 7000, and an injection device 8000.

[0100] The first base 1000 serves as the main body of the portable needle-free injection system, supporting the puncture device 2000, air source, first pipeline 4000, pressure regulating valve 5000, solenoid valve 6000, controller 7000, and injection device 8000. The first base 1000 contains a first compartment 1001 and a second compartment 1002, and a handle 1003 is located on one side of the first base 1000.

[0101] The puncture device 2000 is disposed within the first chamber 1001 of the first base 1000. A gas source containing high-pressure gas, which can be a small high-pressure gas cylinder 600, is replaceably installed within the puncture device 2000. A first pipe 4000 is disposed within the first base 1000, with its first end connected to the puncture device 2000. A pressure regulating valve 5000 is disposed near the first end of the first pipe 4000 for adjusting the output pressure of the first pipe 4000.

[0102] A solenoid valve 6000 is located at the second end of the first pipe 4000 to control the gas output from the first pipe 4000. A controller 7000 is located inside the first base 1000 and is electrically connected to the solenoid valve 6000. The power input end of the injection device 8000 is connected to the first pipe 4000, and the injection device 8000 can be housed in and removed from the second chamber 1002.

[0103] The puncture device 2000 can obtain high-pressure gas from the gas source and transmit the high-pressure gas to the first pipe 4000 and the injection device 8000.

[0104] The embodiment of the present invention integrates the puncture device 2000, the gas source and the injection device 8000 into one unit, which is convenient to carry. The pressure of the high-pressure gas transmitted to the injection device 8000 can be easily adjusted by setting the pressure regulating valve 5000, the solenoid valve 6000 and the controller 7000.

[0105] The injection device 8000 is equipped with a power input end and a liquid input end. The power input end is used to obtain high-pressure gas as power, and the liquid input end is used to obtain the liquid to be injected.

[0106] In an exemplary embodiment, the controller 7000 is electrically connected to the pressure regulating valve 5000.

[0107] In an exemplary embodiment, the power input end of the injection device 8000 is connected to the first pipe 4000 via the second pipe 8001 in order to increase the range of motion of the injection device 8000.

[0108] A connector 4003 is fixed on the first base 1000, and the connector 4003 is connected to the output end of the first pipe 4000. One end of the second pipe 8001 is connected to the injection device 8000, and the other end of the second pipe 8001 can be inserted into the connector 4003 to connect to the connector 4003.

[0109] In an exemplary embodiment, the portable needle-free injection system of the present invention further includes: a first gas pressure gauge 4001 and a second gas pressure gauge 4002 disposed on a first conduit 4000, the first gas pressure gauge 4001 and the second gas pressure gauge 4002 being located on both sides of a pressure regulating valve 5000. The first gas pressure gauge 4001 displays the gas pressure of the first conduit 4000 before being regulated by the pressure regulating valve 5000 (i.e., the gas pressure delivered by the puncture device 2000), and the second gas pressure gauge 4002 displays the gas pressure of the first conduit 4000 after being regulated by the pressure regulating valve 5000 (i.e., the gas pressure delivered by the first conduit 4000 to the injection device 8000).

[0110] In an exemplary embodiment, the injection device 8000 is provided with a first wireless transceiver, and the controller 7000 is provided with a second wireless transceiver. The first wireless transceiver is capable of wireless communication with the second wireless transceiver, thereby enabling wireless communication between the injection device 8000 and the controller 7000.

[0111] The injection device 8000 sends a control command to the second wireless transceiver of the controller 7000 via the first wireless transceiver. The controller 7000 controls the switch on the solenoid valve 6000 according to the control command, so that the high-pressure gas with a pressure value of the target value in the first pipeline 4000 is transmitted to the injection device 8000.

[0112] In an exemplary embodiment, the portable needle-free injection system of the present invention further includes a power source (not shown in the figures) that powers the solenoid valve 6000 and the controller 7000.

[0113] In an exemplary embodiment, the portable needle-free injection system of the present invention further includes a cover 9000, one side of which is rotatably mounted to a first base 1000. The cover 9000 and the first base 1000 constitute a housing, in which a puncture device 2000, an air source, a first pipe 4000, a pressure regulating valve 5000, a solenoid valve 6000, a controller 7000, and an injection device 8000 are housed for portability.

[0114] The following is combined with Figures 4 to 30 The puncture device according to an embodiment of the present invention will be described.

[0115] like Figures 4 to 9 As shown, the puncture device of the present invention includes: a second base 100, a pressure rod 200, a connecting rod 300, a mounting base 400, and a puncture component 500.

[0116] like Figure 4 , Figure 8 and Figure 9 As shown, the second base 100 has a first receiving cavity 101 with an upward opening. A locking groove 103 is provided on the side wall of the first receiving cavity 101 near one end 102 of the second base 100. The locking groove 103 is inclined towards one end 102 of the second base 100 in a downward direction. A piercing guide surface 105 is provided between the locking groove 103 and the upper edge 104 of the second base 100.

[0117] The first end 201 of the pressure bar 200 is pivotally connected to one end 102 of the second base 100. The first end of the connecting rod 300 is pivotally connected to a position of the pressure bar 200 near the first end 201.

[0118] like Figure 4 and Figure 5 As shown, one end of the mounting base 400 is pivotally connected to the connecting rod 300. The mounting base 400 has a through second receiving cavity 401. The side wall of the mounting base 400 has a strip groove 402 extending along the length direction of the second receiving cavity 401. A fixing part 403 is provided at one end 102 of the mounting base 400 away from the second base 100. The fixing part 403 is used to fix the small high-pressure gas cylinder 600 to be punctured.

[0119] like Figure 4 and Figure 5 As shown, the puncture member 500 is disposed in the second receiving cavity 401 and can slide along the second receiving cavity 401. One end of the puncture member 500 has a needle 501, and the puncture member 500 has a guide portion 502 that extends out of the strip groove 402.

[0120] Wherein, when the pressure rod 200 moves from the first position around one end 102 of the second base 100 in the first rotation direction (i.e., Figures 4 to 7 When the direction of arrow A in the diagram is rotated to the second position, the pressure rod 200 first drives the guide part 502 to rotate to a state that contacts the upper edge 104 of the second base 100 so as to slide along the piercing guide surface 105, and then enters the locking groove 103, thereby causing the fixing part 403 to enter the first receiving cavity 101.

[0121] Alternatively, the pressure rod 200 can first drive the guide part 502 to rotate to a state of contact with the piercing guide surface 105 of the second base 100 via the connecting rod 300 so that it can slide along the piercing guide surface 105 and then enter the locking groove 103, thereby allowing the fixing part 403 to enter the first receiving cavity 101.

[0122] As the guide 502 slides along the puncture guide surface 105, the guide 502 drives the puncture member 500 to move relative to the second receiving cavity 401 toward the fixing part 403, so as to puncture the small high-pressure gas cylinder 600 fixed on the fixing part 403.

[0123] In this invention, with the cooperation of the guide part 502 and the upper edge 104 of the second base 100, the piercing guide surface 105, and the locking groove 103, the pressure rod 200 and the connecting rod 300 drive the fixing part 403 of the mounting base 400 and the small high-pressure gas cylinder fixed on the fixing part 403 to enter or leave the first receiving cavity 101 of the second base 100. During the downward sliding along the piercing guide surface 105, the guide part 502 drives the piercing member 500 to move relative to the second receiving cavity 401 towards the fixing part 403 to pierce the small high-pressure gas cylinder fixed on the fixing part 403. The locking groove 103 can lock the guide part 502, thereby preventing the operator from accidentally opening the pressure rod 200 and avoiding danger.

[0124] In an exemplary implementation, such as Figure 8 As shown, the upper edge of the second base 100 is provided with a downwardly recessed groove 106. The groove 106 communicates with the locking groove 103 and is located on the side of the locking groove 103 away from the piercing guide surface 105. During the opening of the pressure rod 200, the groove 106 makes it easier for the guide part 502 to disengage from the locking groove 103.

[0125] In one implementation scheme, such as Figure 8 and Figure 9 As shown, the puncture guide surface 105 is an arc surface. In another embodiment, the puncture guide surface 105 is a slope (not shown in the figure).

[0126] In an exemplary implementation, such as Figure 10As shown, the side wall of the pressure rod 200 is provided with an L-shaped groove 202, which includes a first sliding groove 203 and a second sliding groove 204. The function of the L-shaped groove 202 is to facilitate the opening of the pressure rod 200.

[0127] The second end of the connecting rod 300 is pivotally connected to the L-shaped groove 202 and can slide along the first slide groove 203 and the second slide groove 204 of the L-shaped groove 202.

[0128] In an exemplary implementation, such as Figure 11 As shown, the mounting base 400 includes a mounting base body 404 and the fixing part 403. The second receiving cavity 401 includes a first space 405, a second space 406 and a third space 407 connected in sequence. The first space 405 and the second space 406 pass through the mounting base body 404, and the third space 407 passes through the fixing part 403. The fixing part 403 is fixed to the second space 406, and the inner diameter of the second space 406 is larger than the inner diameter of the first space 405.

[0129] In an exemplary implementation, such as Figure 11 As shown, the third space 407 includes a sliding subspace 409, a needle subspace 410, and a locking subspace 411 that are connected in sequence.

[0130] In an exemplary embodiment, one end of the mounting base body 404 is pivotally connected to the connecting rod 300, and the other end of the mounting base body 404 is pivotally connected to a position near the first end 201 of the pressure rod 200.

[0131] In an exemplary implementation, such as Figures 12 to 14 As shown, the puncture component 500 includes a puncture component body 503 and a needle 501. The interior of the puncture component body 503 has a fluid cavity 504, and the outer peripheral surface of the needle 501 has a recess 505. The side wall of the fluid cavity 504 of the puncture component body 503 has a guide groove 511, and the third space 407 of the second receiving cavity 401 is connected to the fluid cavity 504 through the guide groove 511.

[0132] In an exemplary implementation, such as Figure 13 As shown, the puncture component body 503 includes a connecting part 506, a limiting part 507, a blocking part 508, and a sliding part 509 connected in sequence.

[0133] The limiting part 507 is located in the second space 406. The inner diameter of the limiting part 507 is adapted to the inner diameter of the second space 406. The blocking part 508 is adapted to the inner diameter of the sliding subspace 409. The diameter of the sliding part 509 is smaller than the inner diameter of the sliding subspace 409. The outer peripheral surface of the sliding part 509 has the guide groove 511.

[0134] The connecting part 506 is connected to the tracheal connector 412. At least a portion of the sealing part 508 is located within the sliding subspace 409 to prevent high-pressure gas within the sliding subspace 409 from flowing into the second space 406 and the first space 405. The sliding part 509 is located within the sliding subspace 409.

[0135] In an exemplary implementation, such as Figure 12 and Figure 13 As shown, the puncture component body 503 further includes a sealing ring 510. The sealing ring 510 can prevent high-pressure gas in the sliding subspace 409 from flowing to the second space 406 and the first space 405, thereby preventing gas leakage.

[0136] In another implementation scheme, such as Figure 22 As shown, the side wall of the first receiving cavity 101 is provided with a support 107, the first end of the support 107 is pivotally connected to one end 102 of the second base 100, and the second end of the support 107 is provided with the puncture guide surface 105.

[0137] exist Figure 22 In the implementation scheme, the puncture device does not include the connecting rod 300, and the pressure rod 200 directly drives the guide part 502 to rotate.

[0138] exist Figure 22 In one embodiment, one end of the mounting base 400 is pivotally connected to the circular groove 206 of the pressure rod 200, the circular groove 206 being located near the first end 201 of the pressure rod 200 (see also [reference]). Figure 23 ).

[0139] like Figure 24A and Figure 24B As shown, the support 107 includes an integrally formed mounting portion 110 and a support portion 111. The mounting portion 110 is pivotally connected to the second base 100 via a shaft 108. The support portion 111 is located above the second base 100 and corresponds vertically to the side wall of the second base 100, while the mounting portion 110 is located outside the side wall of the second base 100 (see attached diagram). Figure 25A and Figure 25B ).

[0140] like Figure 25A As shown, when the support 107 rotates around the axis 108 to the state where the lower surface of the support portion 111 is in contact with the upper edge 109 of the second base 100 (i.e., the lower surface of the groove 106), the side wall 112 of the mounting portion 110 and the side wall 113 of the support portion 111 are aligned with the upper side wall of the locking groove 103.

[0141] The operation of the puncture device according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0142] Figure 4 The implementation process of the scheme is as follows:

[0143] exist Figure 4 and Figure 5 In this state, the mounting base 400 and the second base 100 form a certain angle, and the pressure rod 200 is in the first position.

[0144] like Figure 6 and Figure 7 As shown, a small high-pressure gas cylinder 600 is fixed to the fixing part 403 of the mounting base 400.

[0145] The second end 205 of the pressure rod 200 is pressed down, and the pressure rod 200 rotates from the first position around one end 102 of the second base 100 in the first rotation direction (i.e., Figure 6 and Figure 7 (In the direction of arrow A) rotate. The pressure rod 200, through the connecting rod 300, first drives the guide part 502 to rotate directly until it contacts the piercing guide surface 105 of the second base 100 (see the diagram for details). Figure 15A and Figure 15B Slide along the puncture guide surface 105.

[0146] As the guide portion 502 slides along the puncture guide surface 105, the puncture guide surface 105 applies a pushing force to the guide portion 502. This pushing force propels the guide portion 502 along the strip groove 402 toward one end 102 away from the second base 100 (see also [reference]). Figure 16A As the guide portion 502 moves along the strip groove 402 toward one end 102 away from the second base 100, the guide portion 502 drives the piercing member 500 to move relative to the second receiving cavity 401 of the mounting base 400 toward the fixing portion 403, so that the piercing needle 501 of the piercing member 500 pierces the small high-pressure gas cylinder 600 fixed on the fixing portion 403 (see also [reference]). Figure 16B and Figure 16C ).

[0147] The guide part 502 slides downwards along the piercing guide surface 105 from its initial position C to its maximum piercing position D, and continues to slide downwards to its final position E (see also [reference]). Figure 17 ).

[0148] When the guide part 502 slides down the piercing guide surface 105 from the initial position C to the maximum piercing position D, the piercing member 500 moves to the maximum position relative to the second receiving cavity 401 of the mounting base 400 towards the fixing part 403. At this time, the piercing needle 501 penetrates the small high-pressure gas cylinder 600 to the deepest depth.

[0149] As the guide portion 502 slides down the puncture guide surface 105 from the maximum puncture position D to the end position E, the puncture member 500 moves away from the fixing portion 403 relative to the second receiving cavity 401 of the mounting base 400. After passing the end position E, the guide portion 502 begins to move to the left along the strip groove 402 until it returns to the leftmost end of the strip groove 402.

[0150] The guide part 502 slides downward from the end position E of piercing the guide surface 105 to the locking groove 103, and the locking groove 103 can lock the guide part 502.

[0151] After the rubber stopper of the small high-pressure gas cylinder 600 is punctured, the high-pressure gas inside the small high-pressure gas cylinder 600 flows into the puncture subspace 410 and sliding subspace 409 of the third space 407 of the second receiving cavity 401 (see also [reference]). Figure 18 Specifically, within the needle subspace 410 of the third space 407, high-pressure gas flows into the sliding subspace 409 through the recess 505 of the needle 501.

[0152] Within the sliding subspace 409, high-pressure gas flows through the guide groove 511 into the fluid cavity 504 of the puncture component body 503, and then into the tracheal connector 412.

[0153] When the guide part 502 slides into the locking groove 103 (see also...) Figure 19A , Figure 19B and Figure 19C As long as there is high-pressure gas in the small high-pressure gas cylinder 600, the high-pressure gas flowing out or spraying from the small high-pressure gas cylinder 600 will push the piercing component body 503 and the piercing needle 501 towards one end 102 near the second base 100, causing the piercing component body 503 and the piercing needle 501 to move towards one end 102 near the second base 100. This, in turn, causes the guide part 502 to move further downwards along the locking groove 103 towards one end 102 near the second base 100, thereby locking the guide part 502 in the locking groove 103 (see also...). Figure 20A , Figure 20B and Figure 20C This configuration prevents accidental opening of the lever 200 by staff, thus avoiding potential danger. At this point, the lever 200 is in the second position.

[0154] After the high-pressure gas in the small high-pressure gas cylinder 600 is released, the piercing component body 503 and the piercing needle 501, which are no longer propelled by the high-pressure gas, allow the guide part 502 to move upward along the locking groove 103.

[0155] Pushing the second end 205 of the pressure rod 200 upward, the pressure rod 200 moves from the second position around one end 102 of the second base 100 in the second rotation direction (i.e., Figure 20A and Figure 20B (In the direction of arrow B) rotate. The pressure rod 200 first drives the guide part 502 to move upward along the locking groove 103 via the connecting rod 300, and then moves upward along the piercing guide surface 105, and finally leaves the upper edge 104 of the second base 100.

[0156] When the pressure rod 200 rotates in the second direction (i.e., Figure 20A and Figure 20B After rotating back to the first position (in the direction of arrow B), the fixing part 403 of the mounting base 400 is located above the first receiving cavity 101 of the second base 100. At this time, the small high-pressure gas cylinder 600 that has released the high-pressure gas is located above the first receiving cavity 101 of the second base 100. The small high-pressure gas cylinder 600 that has released the high-pressure gas can be removed and replaced with a new small high-pressure gas cylinder 600.

[0157] In addition to the embodiments described above, the guide portion 502 is directly rotated to a state where it contacts the piercing guide surface 105 of the second base 100 (see also [reference]). Figure 15A and Figure 15B The guide part 502 can also be rotated to contact the upper edge 104 of the second base 100 (see details for matching). Figure 21 Then, move it to the right along the upper edge 104 of the second base 100 until it contacts the piercing guide surface 105 (see details). Figure 15A and Figure 15B During this rightward movement, the guide 502 causes the piercing member 500 to move a short distance relative to the second receiving cavity 401 toward the fixing part 403. However, this short distance is insufficient for the piercing needle 501 to pierce the small high-pressure gas cylinder 600 fixed on the fixing part 403.

[0158] Figure 22 The implementation process and Figure 4 The differences in the operational processes of the implementation plans are as follows:

[0159] Press down the pressure rod 200, causing the pressure rod 200 to rotate in the first direction of rotation (i.e., Figure 26 , Figure 27 and Figure 28 (In the direction of arrow A) the lever rotates, and the pressure rod 200 directly drives the guide part 502 to rotate until it contacts the upper edge 114 of the support part 111 of the support 107 of the second base 100 or the pierced guide surface 105, so that it slides along the pierced guide surface 105, and finally causes the guide part 502 to slide into the locking groove 103 (see the diagram for details). Figure 29 ).

[0160] After the high-pressure gas in the small high-pressure gas cylinder 600 is completely released, the second end 205 of the pressure rod 200 is pushed upwards. The pressure rod 200 moves from the second position around one end 102 of the second base 100 in the second rotation direction (i.e., Figure 29 and Figure 30 The lever 200 rotates in the direction of arrow B in the diagram. This rotation drives the guide 502 to rotate in the second direction of rotation (i.e., the direction of arrow B in the diagram). Figure 29 and Figure 30 Rotate in the direction of arrow B in the diagram.

[0161] After the guide 502 disengages from the locking groove 103, the guide 502 pushes the support 107 around the axis 108 in the second rotation direction (i.e., Figure 29 and Figure 30 The support 107 rotates in the direction of arrow B, making room for the rotation of the guide 502. After the guide 502 passes the support 107, the support 107 rotates around the axis 108 in the second rotation direction (i.e., ...) under its own weight. Figure 29 and Figure 30 (The direction of arrow B in the image) rotates back. Figure 26 The state.

[0162] The operation of the portable needle-free injection system according to the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0163] When using, open the cover 9000.

[0164] Observe the first gas pressure gauge 4001 and the second gas pressure gauge 4002, and rotate the pressure regulating valve 5000 until the pressure value displayed by the second gas pressure gauge 4002 is the target value.

[0165] Remove the injection device 8000 and the second conduit 8001 from the second chamber 1002.

[0166] Connect the other end of the second pipe 8001 to the connector 4003 and align the liquid outlet with the skin.

[0167] The solenoid valve 6000 can be directly operated to allow the injection device 8000 to obtain high-pressure gas with the target pressure value. Alternatively, the solenoid valve 6000 can be controlled wirelessly via the controller 7000 by operating the switch on the injection device 8000 to obtain high-pressure gas with the target pressure value.

[0168] After use, remove the other end of the second pipe 8001 from the connector 4003, and then store the injection device 8000 and the second pipe 8001 into the second chamber 1002.

[0169] Finally, close the cover 9000 and lift it away using handle 1003.
