[0001] This utility model relates to the field of medical device technology, and in particular to a novel portable cerebral blood flow monitoring probe. Background Technology

[0002] In the field of medical device technology, research and development focus on various medical devices, instruments, appliances, materials, and other related items. In particular, the portable cerebral blood flow monitoring probe used in neurology is an innovative design in this field. It is specifically designed to monitor the cerebral blood flow velocity and blood volume in real time. This probe operates based on the Doppler effect of ultrasound, working by emitting ultrasound waves into brain tissue and receiving reflected signals. Proper protection of the probe is crucial, as it not only affects the probe's performance and lifespan but also directly relates to patient safety and the quality of medical services.

[0003] Most existing portable cerebral blood flow monitoring probes used in neurology are exposed and lack protective measures. They are easily dropped due to accidental collisions during placement, causing damage to the probes. In addition, during use, the probes are easily contaminated by debris, which not only corrodes the probe surface but also reduces its performance, leading to further damage and increased maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing portable cerebral blood flow monitoring probes are mostly exposed, lack protective measures, are easily damaged by collisions and drops, and are easily contaminated by debris during use, which reduces performance and increases maintenance costs. Therefore, we propose a new type of portable cerebral blood flow monitoring probe.

[0005] To achieve the above objectives, this application adopts the following technical solution: a novel portable cerebral blood flow monitoring probe, comprising a handle, a probe body mounted on the top of the handle, a protective cover on the top of the probe body, connecting shells fixedly connected to both sides of the protective cover, fixing shells fixedly connected to both sides of the probe body, a sliding rod slidably connected to one side of the fixing shell, a circular plate fixedly connected to one end of the sliding rod, a lower boss fixedly connected to the other end of the sliding rod, an upper boss slidably connected to the top of the lower boss, an elastic locking block fixedly connected to the top of the upper boss, and a slot for cooperating with the elastic locking block being provided inside the connecting shell.

[0006] Preferably, a first slider is fixedly connected to the bottom of the lower boss, and a first groove is provided inside the fixed shell to cooperate with the first slider.

[0007] Preferably, a second slider is fixedly connected to both sides of the upper boss, and a second groove is provided inside the fixed shell to cooperate with the second slider.

[0008] Preferably, a spring is fixedly connected to one side of the lower boss, and the other end of the spring is fixedly connected to one side inside the fixed shell.

[0009] Preferably, push rods are slidably connected to both sides inside the connecting shell, and a push plate is fixedly connected to one end of each push rod.

[0010] Preferably, a sealing gasket is provided at the front end of the probe body, the other end of the sealing gasket abuts against the protective cover, and rubber gaskets are fixedly connected around the probe body.

[0011] Preferably, grooves are provided on both sides of the handle, and a coarse-textured anti-slip pad is fixedly connected inside the groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, a circular plate is pushed to move a sliding rod into the interior of the fixed shell, causing the lower boss to move. Under the action of the sliding rod, the upper boss is squeezed upward by the lower boss, causing the elastic block to move towards the connecting shell. During this process, the two ends of the top of the elastic block are squeezed by the inclined surface inside the connecting shell, smoothly inserting into the slot to fix the protective cover. At the same time, the above process allows for quick release of the protective cover, making operation convenient. It can protect the probe body, effectively preventing damage caused by accidental collisions during placement, extending the service life of the probe body, maintaining the cleanliness of the probe body, and reducing maintenance costs.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a novel portable cerebral blood flow monitoring probe, including a handle 1, a probe body 2 mounted on the top of the handle 1, a protective cover 3 on the top of the probe body 2, connecting shells 4 fixedly connected to both sides of the protective cover 3, fixing shells 5 fixedly connected to both sides of the probe body 2, a sliding rod 6 slidably connected to one side of the fixing shell 5, a circular plate 7 fixedly connected to one end of the sliding rod 6, a lower boss 8 fixedly connected to the other end of the sliding rod 6, an upper boss 9 slidably connected to the top of the lower boss 8, and an elastic locking block 10 fixedly connected to the top of the upper boss 9. The connecting shell 4 has a slot 11 inside that cooperates with the elastic locking block 10. Pushing the circular plate 7 drives the sliding rod 6. The probe moves into the interior of the fixed housing 5, causing the lower boss 8 to move. Driven by the slide rod 6, the upper boss 9 is pressed upward by the lower boss 8, causing the elastic block 10 to move towards the connecting housing 4. During this process, the two ends of the top of the elastic block 10 are pressed by the inclined surface inside the connecting housing 4, and smoothly insert into the slot 11 to fix the protective cover 3. At the same time, the above process can quickly release the fixation of the protective cover 3. The operation is convenient and can protect the probe body 2, effectively avoiding damage caused by accidental collisions during placement, extending the service life of the probe body 2, and keeping the probe body 2 clean, thus reducing maintenance costs.

[0021] Reference Figure 2 As shown in this embodiment: the bottom of the lower boss 8 is fixedly connected to the first slider 12, and the inside of the fixed shell 5 is provided with a first slide groove 13 that cooperates with the first slider 12. By setting the structure of the first slider 12 and the first slide groove 13, the movement path of the lower boss 8 is effectively constrained and shaking is prevented.

[0022] Reference Figure 2 As shown in this embodiment: both sides of the upper boss 9 are fixedly connected with second sliders 14, and the inside of the fixed shell 5 is provided with a second sliding groove 15 that cooperates with the second sliders 14. By setting the structure of the second sliders 14 and the second sliding groove 15, the movement trajectory of the upper boss 9 can be restricted to avoid deviation, and it also plays a role in assisting movement.

[0023] Reference Figure 2As shown in this embodiment: a spring 16 is fixedly connected to one side of the lower boss 8, and the other end of the spring 16 is fixedly connected to one side of the inside of the fixed shell 5. Push rods 17 are slidably connected to both sides inside the connecting shell 4. A push plate 18 is fixedly connected to one end of the push rod 17. When fixing the protective cover 3, the lower boss 8 is moved forward by pushing the slide rod 6, which squeezes the upper boss 9 to move upward, causing the elastic block 10 to be smoothly inserted into the slot 11. At this time, the spring 16 is in a compressed state. The rebound force of the spring 16 pushes the lower boss 8 to move towards the circular plate 7. When it is necessary to release the protective cover 3, the push plate 18 is pressed at the same time to drive the push rod 17 to squeeze the two ends of the top of the elastic block 10, so that it is disengaged from the slot 11. This achieves the release of the protective cover 3. The operation is convenient and easy for the operator to use next time.

[0024] Reference Figure 3 As shown in this embodiment: a sealing gasket 19 is provided at the front end of the probe body 2, and the other end of the sealing gasket 19 abuts against the protective cover 3. Rubber gaskets 20 are fixedly connected around the probe body 2. By setting the structure of the rubber gaskets 20, the probe body 2 can be protected against collisions around its perimeter and sides. At the same time, the structure of the sealing gasket 19 can effectively prevent the intrusion of moisture and dust, thereby protecting the internal electronic components and sensors from damage.

[0025] Reference Figure 4 As shown in this embodiment: grooves 21 are provided on both sides of the handle 1, and a coarse textured anti-slip pad 22 is fixedly connected inside the groove 21. By setting the structure of the coarse textured anti-slip pad 22, the friction between the handle 1 and the operator's hand is significantly increased, preventing the probe from slipping due to wet hands during operation, improving the overall stability of operation, and the structure of the groove 21 provides better support and grip for the operator's hand.

[0026] Working principle: The user pushes the circular plate 7 to move the sliding rod 6 into the fixed shell 5, causing the lower boss 8 to move. Under the action of the sliding rod 6, the upper boss 9 is squeezed upward by the lower boss 8, causing the elastic block 10 to move towards the connecting shell 4. During this process, the two ends of the top of the elastic block 10 are squeezed by the inclined surface inside the connecting shell 4, smoothly inserting into the slot 11 to fix the protective cover 3. At the same time, the above process can quickly release the fixation of the protective cover 3. The operation is convenient and can protect the probe body 2, effectively avoiding damage caused by accidental collisions during placement, extending the service life of the probe body 2, and keeping the probe body 2 clean, reducing maintenance costs. By setting the structure of the first slider 12 and the first sliding groove 13, the movement path of the lower boss 8 is effectively constrained to prevent shaking. By setting the structure of the second slider 14 and the second sliding groove 15, the movement trajectory of the upper boss 9 can be restricted to prevent deviation and play an auxiliary role in movement. When the protective cover 3 is fixed, the lower boss 8 is moved forward by pushing the slide rod 6, and the upper boss 9 is moved upward by squeezing it. This causes the elastic block 10 to be smoothly inserted into the slot 11. At this time, the spring 16 is compressed. The spring 16 pushes the lower boss 8 towards the circular plate 7 by its rebound force. When it is necessary to release the protective cover 3, the push plate 18 is pressed at the same time to drive the push rod 17 to squeeze the two ends of the top of the elastic block 10, so that it is disengaged from the slot 11. This achieves the release of the protective cover 3. The operation is convenient and easy for the operator to use next time. The structure of the rubber pad 20 can protect the probe body 2 from collisions around and on both sides. At the same time, the structure of the sealing pad 19 can effectively prevent the intrusion of moisture and dust, thereby protecting the internal electronic components and sensors from damage. The structure of the textured anti-slip pad 22 significantly increases the friction between the handle 1 and the operator's hand, preventing the probe from slipping due to wet hands during operation and improving the overall stability of operation. The structure of the groove 21 provides better support and grip for the operator's hand.
