Description

Technical Field

[0001] The invention relates to the field of ejection devices, and in particular to a biosensor ejection device for body fluid detection. Background Art

[0002] The existing blood sugar test requires the skin to be punctured before testing, but sometimes patients are afraid to puncture the skin when testing by themselves. Therefore, a device is needed that can puncture the skin before testing when performing blood sugar monitoring, and is easy to use and carry. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the existing blood sugar (physical and chemical parameters of body fluids) monitoring devices do not have the function of automatic ejection and pierce the patient's skin. The present invention provides a biosensor ejection device for body fluid detection, which can be used to autonomously pierce the skin and input the value into the biosensor, so as to facilitate the subsequent monitoring of the physical and chemical parameters of the body fluids. The device has a simple structure, is easy to use and can be used multiple times, so as to solve the defects caused by the prior art.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A biosensor ejection device for body fluid detection, comprising an outer shell, an inner shell, a button, and an ejection assembly installed inside the outer shell, wherein the button is installed on the top of the outer shell and is driven and connected to the ejection assembly, and the inner shell is inserted into the inner shell from the bottom of the outer shell;

[0006] The ejection assembly comprises an upper slider, a lower slider, a central shaft, and a guide sleeve. The bottom of the button is connected to a button connector that is in contact with the top of the lower slider. A fixing ring is installed at the bottom of the lower slider. Hooks are symmetrically provided on both sides of the lower slider. A slot group matching the hooks is provided on the inner shell. A slot hole matching the hooks is provided on the upper slider. The upper slider is arranged inside the lower slider. A fixing shaft connected to the central shaft is provided inside the button. The central shaft passes through the button connector and the upper slider in sequence and is then inserted into the guide sleeve. A button spring is provided on the outer sleeve of the fixing shaft. A first tension spring is provided on the outer sleeve of the guide sleeve. A second tension spring is provided between the fixing column installed on the inner shell and the lower slider.

[0007] In the above-mentioned biosensor ejection device for body fluid detection, the portion of the inner shell that protrudes into the outer shell extends to the periphery of the button connector.

[0008] In the above-mentioned biosensor ejection device for body fluid detection, the button connector is composed of a fixed sleeve and a guide rod connected to the bottom of the fixed sleeve and matching the hook.

[0009] In the above-mentioned biosensor ejection device for body fluid detection, the bottom of the guide rod is an inclined surface matching the top of the hook.

[0010] In the above-mentioned biosensor ejection device for body fluid detection, the slot group includes an upper slot and a lower slot arranged on the inner shell.

[0011] In the above-mentioned biosensor ejection device for body fluid detection, a mounting hole is provided at the bottom of the guide sleeve, and a through hole matching the mounting hole is provided on the lower sliding block.

[0012] The two ends of the central axis are respectively connected to the button and the guide sleeve to form the axis for the entire ejection device to slide up and down. The upper slider, the central axis, and the guide sleeve constitute an upper slider module, and its main function is to serve as a slotted needle holder. The fixing ring is used to fix the launcher base and eject the launcher base. The launcher base is mainly used to fix the biosensor and contain the launcher. The launcher base is also the target to be ejected by the ejector. The second tension spring is responsible for providing power for the retraction of the slotted needle.

[0013] When in use, first install the slotted needle on the installation hole at the bottom of the guide sleeve, install the transmitter base on the fixing ring, press the button, and under the action of the first tension spring and the second tension spring, the two hooks on the outer side of the lower slider are disengaged from the upper slot on the inner shell, and the hooks drive the upper slider to slide downward to perform an ejection puncture action, implant the biosensor in the transmitter base into the human body, and fix the entire transmitter base on the skin with the help of a non-woven fabric adhesive tape, take out the detector signal transmitter and install it on the transmitter base for detection;

[0014] When the lower slider moves down to the lower slot, the puncture action is terminated when the hook is elastically reset to the lower slot;

[0015] At the same time, the upper slider moves upward under the action of the first tension spring to pull the slotting needle back to the initial position, completing the action of withdrawing the slotting needle.

[0016] The technical solution provided by the biosensor ejection device for body fluid detection according to the present invention has the following technical effects:

[0017] The device can be used to autonomously puncture the skin and implant a biosensor, which is convenient for subsequent blood sugar monitoring. It has a simple structure and is easy to use and can be used multiple times. BRIEF DESCRIPTION OF THE DRAWINGS
