[0034] For further information, see Figure 1 to Figure 7 The right button is movably connected to the button compartment 206 on the main body through a slide bar 204, and the button compartment 206 on the main body is provided with a component 1 210 and a component 211.

[0035] For further information, see Figure 1 to Figure 7 The component 1 210 is provided with a cavity 1 212 , and the component 2 211 is provided with a cavity 213 .

[0036] For further information, see Figure 1 to Figure 7 The cavity 1 212 is connected to the key chamber 1 205 on the main body through a fourth pipe 216 , and the cavity 2 213 is connected to the key chamber 1 205 on the main body through a second pipe 214 .

[0037] For further information, see Figure 1 to Figure 7 , the component 1 210 is connected to the pump housing via a sliding rod 204.

[0038] In this embodiment, after pressing two buttons, the liquid medicine is extracted from the medicine storage bin and infused into the subcutaneous tissue through the drug infusion tube. The mechanical pump has a fixed infusion volume each time and the infusion volume can be set between 0.01ml and 0.05ml. The present invention can include a counting device, which counts once after each button is pressed and displays it on the counter, and displays the remaining effective infusion times of the medicine. The counting device can be a Hall switch or other forms.

[0039] A patch 2 106 is arranged above the pump body 101, and a patch 1 105 is arranged below the pump body 101. The patch 1 105 and the patch 2 106 are arranged symmetrically about the pump body 101. The pressing device 1 102 and the pressing device 2 103 are pressing devices of the control system, and there is one symmetrical device on each side of the device. By pressing manually at the same time and then popping up, the function of liquid delivery is realized. The needle-assisting hole 104 and the infusion port are needle-assisting holes arranged on the pump body 101. Through the reserved space, using needle-assisting devices and other equipment, the positioning holes are not limited to four hole positions, and can be 2-5 evenly distributed positioning holes, which can be circular, square or other opening shapes. At the same time, the bottom of the pump body 101 can also be provided with a sticking part such as a patch to attach the mechanical pump of the present invention to the surface of human skin.

[0040] The drug storage bin 207 can be made of a transparent polymer material so that the drug storage can be visually observed before use; or it can be made of an opaque material so that it is invisible when viewed directly from the bottom. The drug storage bin 207 can store 1-5 ml of liquid drug, which can be insulin.

[0041] The infusion port is connected to the external infusion tube in the drug injection system to infuse the drug and store it in the drug reservoir. The infusion tube 107 is a flexible polymer infusion tube. The drug is transported to the outside of the mechanical pump along the infusion tube. When the mechanical pump is applied to the human body surface through a needle aid or other tools, the end of the drug infusion tube 107 is located subcutaneously, and the drug will be directly infused into the subcutaneous part of the human body.

[0042] The pump housing does not represent the shape and appearance of the main body. There is a conventional pressing and spring rebound structure between the left button, the right button, the button compartment 1 205 on the main body and the button compartment 2 206 on the main body, which can rebound back to the initial position after being pressed.

[0043] The left button and the button chamber 1 205 on the main body are combined into a set of liquid medicine extraction and injection systems similar to a needle tube. The contact between the slide bar 204 and the button chamber 1 205 on the main body is an airtight structure. The second pipe 214 and the fourth pipe 216 are two pipes connected to the button chamber 1 205 on the main body at one end. By pressing the left button into the button chamber 1 205 on the main body and popping out from the button chamber 1 205 on the main body for a distance, the liquid is drawn into the vacuum space of the left button and the button chamber 1 205 on the main body through the second pipe 214 and the fourth pipe 216, and when the left button is pressed into the button chamber 1 205 on the main body, the liquid is injected into other components.

[0044] The drug storage bin 207 injects liquid drugs into the drug storage bin 207 through the drug injection hole 208, so as to realize the collection and storage of liquid drugs and provide drugs for the drug infusion system. At the same time, the drug injection hole 208 is a one-way hole, which is only connected when the liquid drug is injected and connected by a syringe, and is closed after the injection is completed and disconnected. At the same time, the third pipeline 215 is connected to the pipeline between the drug storage bin 207 and the drug injection hole 208, so as to realize the connection from the drug storage bin 207 to other components to transmit the liquid in the drug storage bin 207.

[0045] The right button and the button compartment 206 on the main body can form a button system. Figure 4 . Figure 4 In the embodiment, the two structures of component one 210 and component two 211 are special components on the right button, and form a sealed friction contact with the button chamber two 206 on the main body, and the cavity one 212 and cavity two 213 are cavities on component one 210 and component two 211 respectively. Figure 5 , mainly composed of two special sealing friction contact structures, component one 210 and component two 211, and their respective cavities one 212 and two cavities 213.

[0046] Figure 4In the figure, the first pipeline 209, the second pipeline 214, the third pipeline 215 and the fourth pipeline 216 are respectively connected to the button chamber 2 206 on the main body and the opening positions are fixed. Only when the cavity 1 212 and the cavity 2 213 reach the pipeline opening position through the right button, the liquid can be transmitted through the pipeline. When the button moves and the pipeline opening is blocked by the component 1 210 and the component 2 211, the liquid cannot be transported.

[0047] The structure on the main body of the mechanical pump infusion structure is as follows Figure 6 As shown, the main body key chamber and pipelines are removed from the keys and other components. The first pipeline 209, the second pipeline 214, the third pipeline 215 and the fourth pipeline 216 are connected to the openings on the key chamber 2 206 on the main body, and the other ends of the second pipeline 214 and the fourth pipeline 216 are connected to the right end of the key chamber 1 205 on the main body.

[0048] In summary, when the right button is pressed, Figure 7 As shown, the first pipe 209 and the fourth pipe 216 are in a connected state, and the second pipe 214 and the third pipe 215 are in a closed state; Figure 4 As shown, the third pipe 215 is in a connected state with the second pipe 214, and the first pipe 209 and the fourth pipe 216 are in a closed state. When the left button is pressed, the volume of the cavity between the left button and the button chamber 1 205 on the main body is reduced, and the liquid medicine or air in the cavity is discharged through the second pipe 214 or the fourth pipe 216 (only when the other end of 214 or 216 is not in a closed state).

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
