Embodiment 1

[0048] Refer to attached Figure 1-9 As shown, the present invention provides a technical solution: a convenient needle-free injector for antigen, including a needle-free injector 100, a liquid supply assembly 200 and at least two clamping mechanisms 300;

[0049] Refer to attached Figure 1~5 As shown, the needle-free injector 100 includes a support 110, an ejection assembly 120 and a braking assembly 130;

[0050] Wherein, the support 110 also includes a first cavity 111, a high-pressure gas cylinder 112, a push-out tube 113 and a second cavity 114, the support 110 has a first cavity 111 and a second cavity 114, and the second cavity The part 114 is located below the high-pressure gas storage bottle 112, and the support 110 is provided with a high-pressure gas storage bottle 112 and a push-out pipe 113 in sequence from bottom to top. The push-out pipe 113 is fixed to the support 110, the surface of the push-out pipe 113 is provided with a first one-way valve, and a guide r...

Embodiment 2

[0074] Refer to attached Figure 10 As shown, a working method of a portable antigen needle-free injector provided by the embodiment of the present invention includes the following steps:

[0075] S1, inject the antigen mixture into the compression tube: open the pipeline switch 260, use the extrusion spring 220 to extend and push the extrusion piece 230 to squeeze the antigen mixture in the storage bottle 210, and transport the antigen mixture to the compression tube with the help of the delivery tube 250 123 in;

[0076] S2, antigen mixture injection: pull the trigger 133 to move to the right, drive the pull rod 131 to move to the left and compress the second return spring 1362, and the rocker arm 134 moves to the left with the help of the pull rod 131 to produce a rightward arc movement The tendency is to push the striker 135 to move in an arc to the left to hit the striker 1124, and the striker 1124 drives the blocking piece 1125 to move to the left and compress the first...

Abstract

The invention provides a portable antigen needleless injector and a working method thereof, and belongs to the technical field of purification devices. The portable antigen needleless injector comprises a needleless injector body, a liquid supply assembly and at least two clamping mechanisms, and the needleless injector body comprises a bracket, a push-out assembly and a brake assembly. The bracket further comprises a first cavity part, a high-pressure gas storage bottle, a push-out pipe and a second cavity part, the first cavity part and the second cavity part are arranged in the bracket, the second cavity part is located below the high-pressure gas storage bottle, the bracket is sequentially provided with the high-pressure gas storage bottle and the push-out pipe from bottom to top, a gear holder is separated from the gear by rotating a second knob downwards, a first knob is rotated upwards to drive a transmission shaft to enable a deflection wheel to be separated from a cushion block, a lifting seat drives the two lifting rods to ascend to take out a liquid storage bottle for replacement along with reset of a fourth reset spring, and therefore replacement of the liquid storage bottle is convenient.

Description

technical field [0001] The invention belongs to the technical field of needle-free injectors, and in particular relates to a portable antigen-free needle-free injector and a working method thereof. Background technique [0002] The special defense mechanism of the human body to resist pathogenic biological invasion and remove abnormal cells in the body is called immunity. The corresponding defense system is the immune system. Human tissue cells are constantly metabolizing, and a large number of new cells replace aging and damaged cells at any time. The immune system can identify aging and dead cells in time and remove them from the body, thus maintaining the stability of the human body. [0003] Because the human body's own immune system is different, people with low immune function are difficult to remove the virus from the body after exposure to the virus, and are prone to infection when encountering epidemic diseases, while people with good immune function, Epidemic infe...
