Description

Technical Field

[0001] The utility model relates to an electro-otological measuring device, belonging to the technical field of medical equipment. Background Art

[0002] When detecting the acupuncture points inside the ear canal, an ear electrometry measuring device is required, such as a handheld ear electrometry measuring device disclosed in the applicant's prior Chinese patent application CN208243556U. The device can measure the body resistance value of the patient's ear acupuncture points. The probe contacts the acupuncture points on the ear. The probe contacts the trigger switch during the retraction movement and is connected to the electrode on the shell. The electrode contacts the patient's hand to form a current loop, thereby detecting the resistance value on the ear acupuncture points. In the ear electrometry measuring device of this structure, the trigger switch is a spring-touch type. When the probe touches the trigger switch, the measurement starts. Long-term repeated use can easily cause poor contact, and the spring needs to be installed independently, and the structure is relatively complicated. In addition, the probe is not provided with a limit structure for the retraction stroke, and it is easy for the probe to accidentally retract too quickly and hit the inner part of the shell. In view of this, it is necessary to improve the existing ear electrometry measuring device. Utility Model Content

[0003] Therefore, the purpose of the utility model is to provide an electro-otological measuring device to solve the defects of the existing spring-type trigger switch, such as complex installation structure and easy poor contact.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an electro-otolaryngology measuring device, including an electro-otolaryngology pen and a human body electrode sheet, wherein the electro-otolaryngology pen includes a shell, a control circuit board, a probe, a pressure sensor and a reset spring; the control circuit board, the probe and the pressure sensor are arranged inside the shell, a slideway is arranged at the front end of the shell, the probe is arranged in the slideway, the contact part of the probe extends outward in the slideway, the pressure sensor is located on the inner side of the probe, the reset spring presses on the pressure sensor and can apply a force to the pressure sensor in the direction of the probe; the human body electrode sheet, the pressure sensor and the probe are electrically connected to the control circuit board respectively.

[0005] A mounting seat is provided at the front end of the shell, the slide is provided in the mounting seat and extends to the rear end surface of the mounting seat, and the return spring, the pressure sensor and the probe can be inserted into the slide at the rear side of the mounting seat; a spring baffle is installed at the rear side of the mounting seat, and the end of the return spring away from the pressure sensor is pressed against the spring baffle.

[0006] The probe also includes a rod connected to the contact part, a limiting sleeve is sleeved on the outside of the rod, the limiting sleeve is fixed to the front end of the slideway, and the inner diameter of the limiting sleeve is larger than the outer diameter of the rod and smaller than the outer diameter of the contact part.

[0007] The limiting sleeve is a C-shaped sleeve, and an opening for the rod to enter is arranged on its side wall.

[0008] A receiving groove for inserting the limiting sleeve is arranged at the front end of the shell.

[0009] The limiting sleeve is bonded and fixed on the shell.

[0010] The probe comprises a convex block portion in the middle, and a limiting shoulder for blocking the front side of the convex block portion is arranged on the slideway.

[0011] A force transmission block is also arranged between the pressure sensor and the probe, one end of the force transmission block is pressed against the pressure sensor, and the other end is pressed against the probe.

[0012] The force transmission block is provided with an insertion hole, the end of the probe is inserted into the insertion hole, and the rear end surface of the protrusion part is pressed against the force transmission block.

[0013] The control circuit board has a lead wire leading out of the housing, and the human body electrode sheet is connected to the far end of the lead wire.

[0014] By adopting the above technical solution, the electro-otology measuring device of the utility model has the following beneficial effects compared with the prior art:

[0015] 1. The shrapnel trigger switch in the prior art is cancelled, and a pressure sensor is set on the rear side of the probe. When the probe is pressed during the ear electrical measurement, the force is transmitted to the pressure sensor. When the pressure value reaches the preset threshold, it triggers the resistance value data collection, which is equivalent to changing the shrapnel trigger switch to a pressure trigger switch, thereby simplifying the installation structure and improving the detection sensitivity and accuracy.

[0016] 2. A mounting seat is set at the front end of the shell, and the return spring, pressure sensor and probe can be plugged and installed at the rear side of the mounting seat, which is simple and convenient;

[0017] 3. Since the probe is plugged and installed at the rear side of the mounting seat, the inner diameter of the front end of the slideway needs to be larger than the outer diameter of the probe part so that the probe can pass outward. After the probe part passes out, a limit sleeve is set on the outside of the rod part to limit the retraction stroke of the probe, so as to prevent the probe from accidentally retracting too fast and hitting the inner parts of the shell;

[0018] 4. A wire is led out of the control circuit board to the outside of the housing, and the human body electrode sheet is connected to the far end of the wire. When in use, the human body electrode sheet can be applied to the appropriate part of the patient's body, which is convenient and flexible. BRIEF DESCRIPTION OF THE DRAWINGS
