There are at least two types of stimulus probes. The stimulation probe in the embodiment comprises a thermal stimulation probe 2, an electrical stimulation probe 3 and a acupuncture probe 4.
The handle 1 is provided with three receiving spaces 11 for receiving the thermal stimulation probe 2, the electrical stimulation probe 3 and the acupuncture probe 4 respectively. When not in use, the thermal stimulation probe 2, the electrical stimulation probe 3 and the acupuncture probe 4 can be received inside the handle 1. When in use, the utility model can be pushed out.
As shown in fig. 1 and 4, the thermal stimulation probe 2 in this embodiment includes a probe holder 20 and a heating probe 21, and one end of the heating probe 21 is detachably connected to the probe holder 20, so that the probe can be changed one by one in clinic, thereby reducing the risk of cross infection.
The electrostimulation probe 3 comprises a probe holder 20 and a discharge probe 31, and the discharge probe 31 is detachably connected with the probe holder 20.
The acupuncture probe 4 comprises a probe seat 20 and a needle body 41, and the needle body 41 is detachably connected with the probe seat 20. The detachable connection structure can be a snap connection or a threaded connection and the like.
The thermal stimulation probe 2, the electrical stimulation probe 3 and the acupuncture probe 4 are respectively fixedly connected with an operation block 5. The probe seat 20 is in sliding fit with the receiving space 11 in the handle 1, the operation block 5 is fixedly connected with the probe seat 20, and the operation block 5 is arranged in the chute 6 on the surface of the handle 1. The probe holder 20 is slid along the receiving space 11 by sliding the operation block 5, and then the corresponding probe is pushed out or retracted.
The thermal stimulation probe 2 comprises a thermally conductive metal. The acupuncture probe 4 is made of plastic. As shown in FIG. 2, the stimulation end face of the acupuncture probe 4 is a 30 degree bevel, and 30 degrees prevents the acupuncture probe 4 from being too sharp.
Wherein a battery 7 is arranged in the handle 1 for supplying power to the electronic components. The battery 7 can be a rechargeable battery, and a No. 7 battery can also be adopted, and the No. 7 battery is preferably provided with two batteries.
The surface of the handle 1 is provided with a thermal stimulation switch 22 and an electrical stimulation switch 32 which are respectively used for controlling the thermal stimulation probe 2 and the electrical stimulation probe 3.
The shape of the handle 1 is set according to the requirement, and can be round, oval or round and blunt square. The handle 1 is dimensioned as required. The shape and size of the operation block 5 are as required.
If the handle 1 is circular, the diameter of the handle 1 can be designed to be 4cm, and the length can be designed to be 10cm. The operating block 5 is rectangular and may have a length of 1.5cm and a width of 0.5cm.
The working principle of the embodiment is as follows:
if the thermal stimulation is needed, the operation block 5 corresponding to the thermal stimulation probe 2 is slid forwards, so that the thermal stimulation probe 2 is exposed from the handle 1; subsequently, the thermal stimulation switch 22 is pressed, and the heating probe 21 is powered on to start heating. When the thermal stimulation probe is not used, the operation block 5 corresponding to the thermal stimulation probe 2 is slid backwards, so that the thermal stimulation probe 2 is retracted into the handle 1.
If the electric stimulation is needed, the operation block 5 corresponding to the electric stimulation probe 3 is slid forwards, so that the electric stimulation probe 3 is exposed from the handle 1; subsequently, the electrostimulation switch 32 is pressed, and the electrostimulation probe 3 starts operating. When the electric stimulation probe is not used, the operation block 5 corresponding to the electric stimulation probe 3 is slid backwards, so that the electric stimulation probe 3 is retracted into the handle 1.
If the acupuncture probe 4 is required to be used, the operation block 5 corresponding to the acupuncture probe 4 is slid forward to expose the acupuncture probe 4 from the handle 1. When not in use, the operation block 5 corresponding to the acupuncture probe 4 is slid backwards, so that the acupuncture probe 4 is retracted into the handle 1.
For a patient who can normally communicate and is matched with the anesthesia plane measurement, a needle stimulation probe can be used for measuring the plane of analgesia, and a thermal stimulation probe is used for measuring the plane of heat sensation disappearance; for patients who cannot be matched with the anesthesia level measurement, the plane of sensory loss is measured using an electrical stimulation probe, and the plane of sensory loss is measured using a thermal stimulation probe. After the different stimulation probes are used for stimulating the corresponding parts of the patient, when the parts which are not anesthetized are subjected to electric stimulation and thermal stimulation, the patient still generates conditioned reflex such as twitching and avoiding, and the like, thereby being beneficial to judging the plane of anesthesia.
