Further, referring to fig. 1-7, the first part 210 is connected to the pump housing by a slide bar 204.
In this embodiment, after two keys are pressed, the liquid medicine is extracted from the medicine storage bin and is infused subcutaneously through the administration infusion tube, the infusion amount of the mechanical pump is fixed each time, and the infusion amount can be set between 0.01ml and 0.05 ml. The invention may comprise a counting device which counts once after each key press and displays on the counter the number of effective infusions of the remaining medicament. The counting means may be a hall switch or other form.
The upper side of the pump main body 101 is provided with a first application 105, the first application 105 and the second application 106 are symmetrically arranged about the pump main body 101, the first pressing device 102 and the second pressing device 103 are pressing devices of a control system, two sides of the device are symmetrically arranged, the device is sprung up after being pressed manually at the same time to realize the function of liquid conveying, the auxiliary needle holes 104 and the infusion port are auxiliary needle holes arranged on the pump main body 101, and the positioning holes are not limited to four hole sites and can be 2-5 uniformly distributed positioning holes, and can be round, square or other opening shapes by utilizing equipment such as an auxiliary needle device through reserved space. Meanwhile, the bottom of the pump main body 101 can be provided with an adhesive part such as an application part, so that the mechanical pump of the invention can be attached to the skin surface of a human body.
The medicine storage bin 207 can be made of transparent polymer materials, can visually observe medicine storage conditions before use, and can also be made of opaque materials, and can not be seen when being seen from the bottom. The cartridge 207 may store 1-5ml of liquid medicament, which may be insulin.
The infusion port is connected with an external infusion tube in the drug infusion system for drug infusion and storing in the drug storage device. The infusion tube 107 is a flexible polymer infusion tube, and the drug is delivered to the outside of the mechanical pump along the infusion tube, when the mechanical pump is applied to the surface of the human body through tools such as a needle aid, the end of the drug delivery infusion tube 107 is positioned subcutaneously, and the drug is directly infused into the subcutaneous region of the human body.
The pump housing does not represent the shape or appearance of the main body, and conventional pressing and spring bouncing structures exist among the left side key, the right side key, the first key bin 205 on the main body and the second key bin 206 on the main body, and after being pressed, the pump housing can bounce to return to the initial position.
The left side key and the first key bin 205 on the main body are combined into a group of liquid medicine extraction and injection systems similar to needle tubes, the contact between the slide bar 204 and the first key bin 205 on the main body is of an airtight structure, and the second pipeline 214 and the fourth pipeline 216 are two pipelines, one ends of each of which is connected with the first key bin 205 on the main body. By pressing the left button into the first key-press bin 205 on the main body and ejecting a distance from the first key-press bin 205 on the main body, liquid is pumped into the vacuum space of the left button and the first key-press bin 205 on the main body through the second pipeline 214 and the fourth pipeline 216, and when the left button is pressed into the first key-press bin 205 on the main body, liquid is injected into other components.
Wherein, the medicine storage bin 207 injects liquid medicine into the medicine storage bin 207 through the medicine injection hole 208, thereby realizing the collection and storage functions of the liquid medicine and providing medicine for the medicine infusion system. Meanwhile, the medicine injection hole 208 is a one-way hole, and is communicated when connected by a syringe only when liquid medicine is injected, and is closed after the injection is finished and disconnected. Meanwhile, the third pipeline 215 is communicated with the pipeline between the medicine storage bin 207 and the medicine injection hole 208, so that other components are communicated from the medicine storage bin 207 to convey liquid in the medicine storage bin 207.
The right button and the second button bin 206 on the main body can form a button system, and the detailed structure is shown in fig. 4. In fig. 4, the first part 210 and the second part 211 are special parts on the right button, and form a sealed friction contact with the second button housing 206 on the main body, and the first cavity 212 and the second cavity 213 are cavities on the first part 210 and the second part 211 respectively. The structure of the right button is shown in fig. 5, and mainly comprises two special sealing friction contact structures of a first part 210 and a second part 211, and a first cavity 212 and a second cavity 213 of the special sealing friction contact structures.
In fig. 4, the first pipe 209, the second pipe 214, the third pipe 215 and the fourth pipe 216 are respectively connected to the second key chamber 206 on the main body, and the opening positions are fixed, so that the liquid can be transported through the pipes only when the first cavity 212 and the second cavity 213 reach the opening positions of the pipes through the right key, and the liquid can not be transported when the key moves and the opening of the pipes is blocked by the first component 210 and the second component 211.
The structure of the main body of the mechanical pump infusion structure is shown in fig. 6, and is a main body key bin and a pipeline without other components such as keys. The first pipe 209, the second pipe 214, the third pipe 215, the fourth pipe 216, etc. are connected with the opening on the key bin two 206 on the main body, and the other ends of the second pipe 214 and the fourth pipe 216 are connected with the right end of the key bin one 205 on the main body.
In summary, when the right button is pressed, as shown in fig. 7, the first pipe 209 and the fourth pipe 216 are in a communication state, the second pipe 214 and the third pipe 215 are in a closed state, and when the button is sprung, as shown in fig. 4, the third pipe 215 and the second pipe 214 are in a communication state, 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 first button housing 205 on the main body is reduced, so that the liquid medicine or air in the cavity can be discharged through the second pipeline 214 or the fourth pipeline 216 (only when the other end of the second pipeline 214 or the fourth pipeline 216 is not in a closed state).
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
