Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that, unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the utility model pertains.

Examples

The present embodiment provides a heater-based oral anesthetic device, as shown in fig. 1, comprising a peristaltic pump 1, a flexible tube 2, and an anesthetic syringe 3 connected in sequence.

The peristaltic pump is provided with a first heater 4 for primary heating of the anesthetic agent. In a specific embodiment, as shown in fig. 2, the first heater includes an electric heating wire, a first temperature sensor and a first controller, and the electric heating wire and the first temperature sensor are electrically connected to the first controller, respectively. The first heater starts to work after the peristaltic pump is powered on. The first controller controls the electric heating wire to heat a storage container which is arranged in the peristaltic pump and used for placing the anesthetic, so that the anesthetic is indirectly heated. The heating temperature of the first heater is configured to be 37 ℃, the first temperature sensor is tightly attached to a storage container for placing anesthetic, the temperature of the anesthetic is monitored in real time, when the temperature of the anesthetic is heated to be 37 ℃, the first controller receives the temperature monitoring value of the first temperature sensor, the working power supply of the electric heating wire is disconnected, and heating is stopped.

The anesthetic injector includes a handle connected to a hose through which anesthetic heated to 37 degrees celsius is delivered to the anesthetic injector. The temperature of the anesthetic agent may drop during delivery. In this embodiment, as shown in fig. 2, a second heater 5 is provided at the connection of the anesthetic syringe handle and the hose for reheating anesthetic. The second heater includes a housing, a liquid, a ceramic heating coil, a second temperature sensor, and a second controller. The shell is annular tube shape, is sleeved on the hose, and is made of rubber or silica gel. Liquid, a second temperature sensor and a ceramic heating ring are arranged in the shell, and insulating layers are wrapped outside the second temperature sensor and the ceramic heating ring. In a specific embodiment, the liquid is distilled water, and the rubber insulating layers are wrapped outside the second temperature sensor and the ceramic heating ring. The ceramic heating ring is electrically connected to a power supply in the handle, which in a specific embodiment is a battery. The second controller is arranged in the handle and is respectively and electrically connected with the second temperature sensor and the ceramic heating ring. Because of the second heater is close to medical personnel's hand, medical personnel bump the second heater during the operation easily, and distilled water, ceramic heating circle nonconducting, in addition the shell is rubber or silica gel, and the outer parcel of ceramic heating circle has the rubber insulation layer, can promote the security of second heater.

When the second heater works, the ceramic heating ring heats the distilled water, the heating temperature of the second heater is configured to be 37 ℃, the temperature of the distilled water is monitored by the second temperature sensor in real time, and when the temperature of the distilled water is heated to 37 ℃, the second controller receives the temperature monitoring value of the second temperature sensor, disconnects the working power supply of the ceramic heating ring and stops heating. The second heater is equivalent to the mode of using the water bath, carries out the secondary heating to the second heater that flows through, the anesthetic of first heating through first heater, because of through the second heater after, the anesthetic only needs to inject the human oral cavity through this a section very short distance of handle, so can guarantee basically that the anesthetic is in 37 degrees centigrade temperature when injecting into human oral cavity inside.

In a specific embodiment, if only the second heater is used, the anesthetic cannot be heated to 37 degrees celsius only by the second heater because the time interval for the anesthetic to pass through the second heater is short, so that the first heater and the second heater need to be used in combination. The operation of the heater-based oral anesthesia apparatus is described in detail below:

the peristaltic pump comprises a driver and a pump head, and in a specific embodiment, the peristaltic pump is controlled to be started and stopped by a pedal pneumatic switch, and the driver of the peristaltic pump is connected with the pedal pneumatic switch. When the patient starts the examination before treatment, the peristaltic pump is electrified, the first heater starts to work, and the electric heating wire is controlled to heat the storage container in the peristaltic pump, wherein the anesthetic is placed in the storage container, so that the anesthetic is heated to 37 ℃.

When the patient needs to be locally anesthetized in the oral cavity, the medical staff steps on the pedal pneumatic switch, the driver of the peristaltic pump starts to work, and the anesthetic is conveyed to the anesthetic injection needle through the hose. The hospital personnel are through pressing the heating switch on the handle, heat 37 degrees centigrade to the distilled water through the ceramic heating circle of second controller control, use the mode of water bath to carry out the secondary heating to the anesthetic that flows through the second heater, inject the anesthetic to the ration in the patient's gum, make the anesthetic of injecting in the patient's gum be in 37 degrees centigrade's temperature basically, can alleviate uncomfortable sense, the pricking sense of patient to the icy liquid.

In a specific embodiment, the first controller and the second controller can be a single chip microcomputer (such as AT89C52), the peristaltic pump can be a micro peristaltic pump, and the driver can be a servo motor.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; while the utility model has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description.
