Embodiment Construction

[0018] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0019] Figure 1a , 1b It is a vertical cross-sectional view showing the structure and operating state of the chemical liquid shut-off valve in the preferred embodiment of the present invention.

[0020] As shown in the figure, the medical solution injection device according to the ideal embodiment of the present invention is provided with a medical solution intermittent valve 51 for detecting the state of cap installation and a detection sensor 44 for detecting the clogged state of the tube, so that the patient can safely inject the medical solution by himself. The above-mentioned liquid medicine intermittent valve 51 can inject liquid medicine only after the pipe is installed and the cover provided on the valve 51 is closed and the setting is completed.

[0021] For this reason, the liquid medicine shut-off valve 51 according to the p...

Abstract

The invention provides a liquid medicine injection device which has a liquid medicine interrupter valve for supplying liquid medicine and detecting sensor according to the installment need of pipe. Wherein, said liquid medicine interrupter valve can be injected liquid medicine when the pipe is installed, closed and relative settings are completed; and said detecting sensor can be used to detect the clogging condition of pipe to inform the patient, therefore, the patient can be injected liquid medicine safely. The liquid medicine interrupter is comprised by valve housing and valve plug while valve housing has input and output with which the inner liquid medicine can flow out to form a cavity inside the valve housing; and the center of valve plug is the small diameter part while its two ends are big diameter parts. The valve plug is in the shape of winding reel whose progressively increases from the center to the two ends, and when the cover is closed, the valve plug can move upward and downward inside the cavity of valve housing.

Description

technical field [0001] The present invention relates to a liquid medicine injection device. Specifically, the liquid medicine injection device is equipped with a liquid medicine intermittent valve capable of supplying the liquid medicine by installing a tube, and a detection sensor that detects the clogged state of the tube and informs the patient. Safely inject the liquid medicine into the patient's body. The above-mentioned medicinal liquid intermittent valve can inject medicinal liquid only under the condition that the cover is closed and the setting is completed after the pipe is installed. Background technique [0002] As we all know, the doctor prescribes the amount of medicine to be injected into the patient on the prescription, and the nurse fixes the liquid medicine container at a position higher than the injection site of the patient according to the doctor's prescription, and adjusts the valve according to experience. The opening and closing part injects a certai...
