Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
In an embodiment of the invention, an intelligent resetting method of an electronic booster based on oral anesthesia injection comprises the following steps:
detecting the remaining amount of the injection liquid in the syringe;
when the injection is not remained, the electronic booster generates a reset signal to control the electronic booster to reset;
when the injection remains, judging whether the remaining amount of the injection changes within a preset time, and when the remaining amount does not change, generating a reset signal by the electronic booster to control the electronic booster to reset.
The invention can judge whether the liquid amount changes or not by the aid of the electronic booster when boosting, judge whether the electric quantity is sufficient or not, and judge whether the electronic booster resets or not according to a specific curve of the liquid amount.
The principle of the technical scheme is as follows: as shown in figure 1, the invention can automatically detect the residual injection liquid in the injector, and the mode of detecting the injection liquid is to judge through the difference value between the pre-filled injection liquid and the injected liquid, or to detect through infrared, and the injected liquid is determined through the boosting distance of the electronic booster and the space specification of the injection needle tube. When the injection is detected to be completely injected, that is, no liquid in the injector remains, a reset signal is generated, and under the reset signal, a doctor pulls out the needle tube, and then, after the needle tube is pulled out, the electronic booster is reset. When the injection remains, if the injection is unchanged within a period of time, that is, the injection cannot be injected, or a doctor pulls out the needle tube, the electronic booster is reset, and the electronic booster is in an initial state during resetting, and does not generate thrust to push the injector for injection.
The beneficial effects of the technical scheme are that: when the invention is used for injection, whether the injection liquid in the injector is completely injected into a patient can be sensed, the medication rate of the patient can be improved, and the waste of the liquid medicine is avoided. Moreover, the invention does not need to be matched manually, and does not need to detect whether the electric quantity of the electronic booster is sufficient manually. The electronic booster can automatically reset, whether the electronic booster is reset or not does not need to be manually judged, and manual reset can be forgotten by doctors, so that the electronic booster can generate thrust when the injector is free of liquid medicine or only in air, quantitative liquid medicine injection cannot be realized, and if the injector is blocked, the electronic booster cannot be manually judged, and the electronic booster can judge whether the injector is blocked or not based on the thrust of the electronic injector, thereby realizing intelligent reset and then carrying out reset alarm.
As a possible embodiment of the present invention, the reset signal includes a manual reset signal and an automatic reset signal.
The principle of the technical scheme is as follows: the invention can have two reset signals, one is a manual reset signal and the other is an automatic reset signal, and both signals can ensure that the electronic booster realizes functional reset.
The beneficial effects of the technical scheme are that: the invention can realize the reset function, so that the electronic booster can stop boosting and prevent the thrust from being generated all the time.
As a possible implementation manner of the invention, the electronic booster comprises a first key, a second key and a third key;
the first key is used for setting injection parameters;
the second key is used for increasing injection;
the third button is used for returning to reset.
Different keys are arranged to perform different function control.
The principle of the technical scheme is as follows: the invention comprises three keys, and can realize the setting of injection parameters including, but not limited to, injection liquid amount, injection force and total liquid amount of the injector. The invention can realize incremental injection, namely, the injection liquid amount is increased incrementally according to the real-time acceptance degree of a patient; and the third key is adopted for manual return reset.
The beneficial effects of the technical scheme are that: the invention can set injection parameters so as to realize intelligent injection and incremental injection, and can also realize manual reset when automatic injection fails or a doctor can need manual reset.
As a possible embodiment of the present invention, the method further includes:
detecting the real-time electric quantity of the electronic booster;
the electric quantity detection of the electronic booster is based on the power management module in the electronic booster, and the electronic booster is provided with a display screen which can display real-time electric quantity.
Judging whether the electric quantity is in an abnormal state or not, and sending a reset control signal to a switch circuit of the electronic booster when the electric quantity is detected to be in the abnormal state;
the abnormal state of electric quantity comprises the state that the electric quantity is insufficient, the charging cannot be carried out, or the electric quantity can be automatically attenuated when the electric quantity is not used, and the abnormal state of the electric quantity belongs to the abnormal state of the electric quantity.
The reset control signal comprises a first control signal and a second control signal after a preset time interval;
the first control signal is used for rapidly powering off the electronic booster, so that the driving motor stops running, and the electronic booster is rapidly stopped.
Under the action of a first control signal, the battery path of the electronic booster is controlled to be disconnected so as to power down the driving motor;
and under the action of a second control signal, controlling the conduction of a passage between the battery and the fuel gauge so as to electrify the fuel gauge again.
The principle of the technical scheme is as follows: the electronic booster can automatically detect the electric quantity, and if the electric quantity is insufficient or the electric quantity is unstable in output, the electronic booster is in an abnormal state, and a reset control signal is generated in the abnormal state. Parameter settings are not possible in the abnormal state when no injection is performed. When the patient is injected, if the electric quantity is sensed to be insufficient, the motor can be automatically powered down, and the motor cannot be powered off in an emergency mode, so that the motor is burnt. And the second control signal is used for controlling the access of the battery and the electricity meter after charging, so as to detect and power up the electricity.
The beneficial effects of the technical scheme are that: the invention can realize the electrification of the electric quantity, carry out the detection control of the electric quantity and prevent the shortage of the electric quantity of the electronic booster.
As a possible embodiment of the present invention, the method further includes:
