Description

Technical Field

[0001] The utility model relates to the technical field of nerve detection equipment, in particular to an ultrasonic device capable of detecting brain nerves. Background Art

[0002] Transient ischemic attack mostly occurs in the elderly aged 50 - 70. When it occurs, the patient may suddenly experience symptoms such as numbness, weakness on one side of the body, vision loss or even visual field defect, speech disorder, etc. It is necessary to further examine the intracranial large arteries through intracranial ultrasound in the hospital to determine whether there is occlusion or the degree of stenosis. During the use of the device, in order to better fit the human body and more clearly present the situation inside the body, the ultrasonic probe often needs to be used together with a coupling agent. However, most of the probes on the market cannot conveniently add the coupling agent for smearing. That is, the use of the coupling agent is generally manually operated by medical staff to squeeze an appropriate amount onto the human body detection site and then smear it. This makes the aggregated coupling agent after extrusion unable to be sprayed in a large area, and at the same time affects the efficiency of ultrasonic detection. Summary of the Utility Model

[0003] Based on this, in view of the above technical problems, it is necessary to provide an ultrasonic device capable of automatically injecting coupling agent and detecting brain nerves.

[0004] An ultrasonic device capable of detecting brain nerves provided by the utility model includes:

[0005] A handle with mounting grooves on both sides and a cavity inside;

[0006] A pressure key disposed in the mounting groove and protruding from the handle;

[0007] A probe fixed to one side of the handle, and the surface for contacting the patient is concave;

[0008] A storage box fixed to the side of the handle away from the probe, and filled with coupling agent inside;

[0009] A shunt block fixed to the side of the probe body close to the patient, and having equally spaced channels inside;

[0010] Wherein, a balloon is installed inside the handle, and both sides of the balloon are fixedly connected to the storage box and the shunt block respectively by flow tubes. One-way valves are installed in both flow tubes on both sides, and the working surfaces of the one-way valves on both sides are opposite.

[0011] In one embodiment, a quadrilateral frame is movably connected inside the balloon. Springs are installed on the quadrilateral frame. Guard plates are installed on two opposite end points of the quadrilateral frame, and the guard plates are fixedly connected to the inner wall of the balloon.

[0012] In one embodiment, one end of the pressure key located inside the handle has a flat plate portion, and the flat plate portion abuts against the balloon.

[0013] In one embodiment, the two sides of the handle are provided with first mounting holes arranged at equal distances. A shunt tube is fixedly installed at one end of the channel away from the patient, and the shunt tube penetrates through the first mounting hole and communicates with the circulation tube.

[0014] In one embodiment, one side of the shunt block close to the patient has a cavity and a sealing block is slidably installed therein. The sealing block is used to block the coupling agent.

[0015] In one embodiment, first air bags are fixedly installed at both ends of the sealing block, second springs are movably installed on the first air bags, a second air bag is arranged between the inner bottom surface of the installation groove and the pressure key, and an air tube is fixedly connected between the first air bag and the second air bag.

[0016] In one embodiment, a second mounting hole is provided in the shunt block, and one end of the air tube away from the second air bag penetrates through the second mounting hole and communicates with the first air bag.

[0017] In one embodiment, a heat conduction film is arranged in the probe, and both ends of the heat conduction film extend between the probe and the shunt block.

[0018] For the above ultrasonic device capable of detecting brain nerves, before detection, medical staff squeeze the pressure keys on both sides and transmit the force to the balloon. The balloon is compressed by the force and squeezes the internal coupling agent into the channel of the shunt block through the circulation tube and the shunt tube in sequence and then adheres to the surface of the probe, facilitating the subsequent coupling agent coating operation and not wasting too much. During detection, release the pressure key and hold the handle. Since the contact end of the probe with the patient has a certain arc, it is convenient to better fit the patient. And during detection, the heat conduction film can transfer the heat energy inside the probe to the rear end and dissipate it, improving the heat dissipation effect.

The term "and / or" used in the description of the present utility model includes any and all combinations of one or more of the related listed items.

[0032] The following Figures 1-5 describes an ultrasonic device for detecting brain nerves of the present utility model.

[0033] As Figure 1 shown, in one embodiment, an ultrasonic device for detecting brain nerves provided by the present utility model includes a handle 100, a pressure key 200, a probe 300, a storage box 400 and a shunt block 500.

[0034] Referring to Figure 2 and Figure 3, both sides of the handle 100 have mounting grooves 110 and a cavity inside; the pressure keys 200 are arranged in the mounting grooves 110 and protrude from the handle 100, facilitating the operator to squeeze; the probe 300 is fixed to one side of the handle 100, and the surface for contacting the patient is concave, so that the area of the probe 300 in contact with the patient's brain is larger; the storage box 400 is fixed to the side of the handle 100 away from the probe 300, and is filled with coupling agent. The surface of the storage box 400 has a flip cover that can be buckled and fixed, facilitating the addition of coupling agent inward; the flow dividing block 500 is fixed to the side of the probe 300 close to the patient, and has equally spaced channels 510 inside. A heat conducting film 310 is arranged in the probe 300, and both ends of the heat conducting film 310 extend between the probe 300 and the flow dividing block 500.

[0035] Optionally, the heat conducting film 310 is a flexible graphite film with a high heat conductivity coefficient, or a metal foil with a high heat conductivity coefficient can also be used. The flexible graphite film has an ultra-high heat conductivity coefficient in the X and Y directions (plane directions), which is 1500 - 1800 W / m·K, while the heat conductivity coefficient in the Z direction (thickness direction) is only 15 W / m·K. The flexible graphite film can conduct heat along the plane of the flexible graphite film to the rear end of the probe 300, while blocking the conduction of heat in the Z direction, and can achieve a good heat conduction effect.

[0036] Among them, a balloon 120 is installed inside the handle 100. Both sides of the balloon 120 are fixedly connected to the storage box 400 and the flow dividing block 500 with flow pipes 122. The handle 100 has equally spaced first mounting holes 130 on both sides. One end of the channel 510 away from the patient is fixedly installed with a flow dividing pipe 520. During the detection process, in order for the coupling agent to be evenly distributed on the surface of the probe 300, the flow dividing pipe 520 penetrates through the first mounting hole 130 and is communicated with the flow pipe 122. One-way valves are installed in both flow pipes 122 on both sides, and the working surfaces of the one-way valves on both sides are opposite.

[0037] For the ultrasonic device capable of detecting brain nerves in this embodiment, before detection, medical staff squeeze the pressure keys 200 on both sides and transmit the force to the balloon 120. The balloon 120 is compressed by the force and squeezes the internal coupling agent into the channels 510 of the flow dividing block 500 through the flow pipes 122 and the flow dividing pipes 520 in sequence and then adheres to the surface of the probe 300, facilitating the subsequent coupling agent coating operation and not wasting too much. During detection, release the pressure keys 200 and hold the handle 100. Since the contact end of the probe 300 with the patient has a certain arc, it can better fit the patient. And during detection, the heat conducting film 310 can transfer the heat energy inside the probe 300 to the rear end and dissipate it, improving the heat dissipation effect.

[0038] Refer to Figure 4, after the medical staff presses the pressure key 200, in order to enable the balloon 120 to reset quickly, a quadrilateral frame 140 with movable connection is arranged inside the balloon 120. A first spring 142 is installed on the quadrilateral frame 140. On two opposite ends of the quadrilateral frame 140, guard plates 150 are installed, and the guard plates 150 are fixedly connected to the inner wall of the balloon 120. One end of the pressure key 200 located inside the handle 100 has a flat plate portion 210, and the flat plate portion 210 abuts against the balloon 120.

[0039] Both ends of the first spring 142 are fixedly connected to two sides of the quadrilateral frame 140. In this way, under the pulling force of the first spring 142, the quadrilateral frame 140 always maintains a stable posture, and can quickly reset and drive the balloon 120 to expand even after being extruded and deformed by an external force. The negative pressure inside the balloon 120 after expansion forces the coupling agent in the storage box 400 to be inhaled into the balloon 120 through the circulation pipe 122 as a supplement.

[0040] As Figure 3 shown, in one embodiment, one side of the shunt block 500 close to the patient has a cavity and a sealing block 530 is slidably installed. The sealing block 530 is used to block the coupling agent. First air bags 540 are fixedly installed at both ends of the sealing block 530. A second spring 542 is movably installed on the first air bags 540. A second air bag 160 is arranged between the inner bottom surface of the installation groove 110 and the pressure key 200. An air pipe 550 is fixedly connected between the first air bag 540 and the second air bag 160. Refer to Figure 5 .

[0041] When the medical staff presses the pressure key 200, the second air bag 160 is also squeezed by the force, and the air inside is transported to the first air bag 540 through the air pipe 550. The inside of the first air bag 540 is quickly filled and drives the second spring 542 to stretch. The sealing block 530 is squeezed by the first air bag 540 and moves into the cavity in the shunt block 500, and the originally blocked channel 510 is opened, and the coupling agent can smoothly discharge from the shunt block 500. When the medical staff no longer presses the pressure key 200, the second spring 542 resets and contracts to discharge the air in the first air bag 540 into the second air bag 160, and at the same time pulls the sealing block 530 to re-block the channel 510 to prevent the coupling agent from flowing out automatically and polluting the internal coupling agent.

[0042] As a preference, in order to avoid damage to the pipeline due to breakage and for aesthetics, the shunt block 500 has a second installation hole 560, and one end of the air pipe 550 far away from the second air bag 160 penetrates through the second installation hole 560 and communicates with the first air bag 540.

[0043] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0044] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
