Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a protective device for an intracranial pressure ultrasound probe. Background Technology

[0002] In clinical settings such as neurology departments and intensive care units in hospitals, intracranial pressure ultrasound probes play a crucial role, serving as one of the key tools for doctors to monitor changes in patients' intracranial pressure. However, the crisscrossing cables of various medical devices and equipment in wards make intracranial pressure ultrasound probes highly susceptible to collisions with surrounding objects during frequent handling, use, and storage. This can lead to scratches and wear on the probe casing, and may even damage the delicate internal ultrasonic transducer components, affecting detection accuracy.

[0003] Currently, some hospitals use homemade cloth bags to store probes. The cloth bags are generally made of soft material, which can prevent the probe from colliding directly with hard objects. However, the cloth bags lack rigid support and cannot provide sufficient shock protection for the precision components inside the probe. When the probe is subjected to a large impact, the internal components may still be displaced or damaged. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a protective device for intracranial pressure ultrasound probes. It solves the technical problem that existing technologies use cloth bags to store probes, which lack rigid support and cannot provide sufficient shock-resistant protection for the precision components inside the probes, thus achieving the goal of providing comprehensive protection for the probes.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a protective device for an intracranial pressure ultrasound probe, including a handle installed on one side of the probe, a protective mechanism for buffering and damping the impact force of the probe falling, and an anti-scratch mechanism to prevent scratching the probe surface.

[0006] The protective mechanism includes a protective shell installed outside the probe, and four double-headed hinge seats are symmetrically installed in a diamond shape between the inner wall of the protective shell and the side of the probe. A connecting arm is rotatably connected between two adjacent double-headed hinge seats through a shaft pin. A buffer spring is installed between two horizontally opposite double-headed hinge seats, and a shock-absorbing component is provided inside the buffer spring to dampen the impact force.

[0007] A further improvement is that the shock absorption assembly includes a sliding sleeve mounted on a double-headed hinge seat and located inside a buffer spring, and the sliding sleeve is filled with hydraulic oil. A piston block is slidably connected to the sliding sleeve from left to right, and a sliding rod is mounted on the side of the piston block and slidably connected to a through hole on the outside of the sliding sleeve. The sliding rod is connected to the double-headed hinge seat on the opposite side.

[0008] A further improvement is that the piston block has fluid flow holes arranged in a ring array, and a sealing gasket is installed between the through hole on the outer side of the sliding sleeve and the sliding rod.

[0009] A further improvement is that multiple flexible springs are arrayed and installed between the upper and lower inner walls of the protective shell and the probe.

[0010] A further improvement is that the anti-scratch mechanism includes an anti-scratch sleeve installed inside the protective shell and located outside the probe, and T-shaped sliders are installed on both sides of the anti-scratch sleeve and are slidably connected to the T-shaped grooves opened on the protective shell. A tension spring is installed between the inner wall of the T-shaped groove and the T-shaped slider, and a locking component is provided on the anti-scratch sleeve to lock its position.

[0011] A further improvement is that the locking assembly includes a compression spring installed on the inner wall of a slot in the anti-scratch sleeve, and a locking slider that is slidably connected to the inner wall of the slot is installed on the outer end of the compression spring. The protective shell has a locking hole that matches the locking slider.

[0012] By employing the above technical solution, this utility model provides a protective device for an intracranial pressure ultrasound probe, which has at least the following beneficial effects:

[0013] 1. When the probe falls, the impact force causes the connecting arm to rotate on the double-headed hinge seat and stretches the buffer spring. The elasticity of the buffer spring is used to absorb and release the impact force, thereby avoiding the displacement and damage of the internal components of the probe due to excessive impact force.

[0014] 2. When the buffer spring is stretched under force, it drives the slide rod to pull the piston block to slide outward of the slide sleeve. Because the slide sleeve is filled with hydraulic oil, as the piston block slides outward, the hydraulic oil is squeezed and flows through the liquid flow hole on the piston block, generating flow resistance, which consumes and weakens the vibration force, thereby achieving shock absorption and better protecting the probe.

[0015] 3. This utility model allows the T-shaped slider to slide down along the inner wall of the T-shaped groove and compress the tension spring by pressing the anti-scratch sleeve until the locking slider overlaps and engages with the locking hole, thereby exposing the probe for use. After use, the anti-scratch sleeve is reset to protect the probe and prevent accidental scratches on the probe surface. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Addressing the issue that existing technologies using cloth bags to store probes lack rigid support and cannot provide sufficient shockproof protection for the probe's internal precision components, this embodiment provides a protective device for intracranial pressure ultrasound probes. Please refer to... Figures 1-6This embodiment provides a protective device for an intracranial pressure ultrasound probe, which can provide comprehensive protection for the probe. The protective device includes a handle 2 installed on one side of the probe 1, a protective mechanism 3 on the probe 1 to buffer and dampen the impact force of a drop, and an anti-scratch mechanism 4 on the probe 1 to prevent scratches on its surface. The protective mechanism 3 absorbs and dampens the impact force generated by the probe 1 being accidentally dropped or collided, thereby preventing damage to the internal electronic components of the probe 1. Combined with the anti-scratch mechanism 4, it protects the probe 1 and prevents accidental scratches on its surface during daily use.

[0033] Because existing technology uses a cloth bag to store the probe, it lacks rigid support and cannot provide sufficient shock protection for the precision components inside the probe. Therefore, this device is equipped with a protective mechanism 3. The protective mechanism 3 includes a protective shell 31 installed on the outside of the probe 1. Four double-headed hinge seats 32 are symmetrically installed in a diamond structure between the inner wall of the protective shell 31 and the side of the probe 1. A connecting arm 33 is rotatably connected between two adjacent double-headed hinge seats 32 through a shaft pin. A buffer spring 34 is installed between two horizontally opposite double-headed hinge seats 32. A shock-absorbing component 35 is installed inside the buffer spring 34 to absorb and buffer the impact force. When the probe 1 is accidentally dropped, the impact force it generates compresses the connecting arm 33 to rotate on the double-headed hinge seat 32 through the shaft pin and stretches the buffer spring 34. The elasticity of the buffer spring 34 is used to absorb and release the impact force, thereby avoiding the displacement and damage of the internal components of the probe 1 caused by excessive impact force.

[0034] If the impact force is too large and reaches the elastic limit of the buffer spring 34, it may cause some damage to the probe 1. Therefore, the device is also equipped with a shock absorption component 35. The shock absorption component 35 includes a sliding sleeve 351 installed on the double-headed hinge seat 32 and located in the buffer spring 34. The sliding sleeve 351 is filled with hydraulic oil. A piston block 352 is slidably connected to the sliding sleeve 351. A sliding rod 353 is installed on the side of the piston block 352 and slidably connected to the through hole opened on the outside of the sliding sleeve 351. The sliding rod 353 is connected to the double-headed hinge seat 32 on the other side.

[0035] The piston block 352 has fluid flow holes arranged in a ring. A sealing gasket is installed between the through hole on the outside of the sliding sleeve 351 and the sliding rod 353. When the buffer spring 34 is stretched by force, it drives the sliding rod 353 to pull the piston block 352 to slide outward of the sliding sleeve 351. Since the sliding sleeve 351 is filled with hydraulic oil, as the piston block 352 slides outward, the hydraulic oil is squeezed through the fluid flow holes on the piston block 352, generating flow resistance, which consumes and weakens the vibration, thereby achieving shock absorption and better protecting the probe 1.

[0036] Multiple flexible springs 36 are arrayed between the upper and lower inner walls of the protective shell 31 and the probe 1. The flexible springs 36 work better with the protective mechanism 3 to provide comprehensive buffering and shock absorption for the probe 1, further improving the protective effect.

[0037] Example 2

[0038] Based on Example 1, such as Figures 1-6 As shown, since the probe 1 may accidentally collide with other medical devices during daily use, causing scratches on the surface of the probe 1, the device is equipped with an anti-scratch mechanism 4. The anti-scratch mechanism 4 includes an anti-scratch sleeve 41 installed inside the protective shell 31 and located outside the probe 1. T-shaped sliders 42 are installed on both sides of the anti-scratch sleeve 41 and are slidably connected to the T-shaped grooves opened on the protective shell 31. A tension spring 43 is installed between the inner wall of the T-shaped groove and the T-shaped slider 42. The anti-scratch sleeve 41 is equipped with a locking component 44 to lock its position. When the probe 1 needs to be used, the anti-scratch sleeve 41 is pressed, so that the T-shaped sliders 42 on both sides slide along the T-shaped grooves opened on the protective shell 31 into the protective shell 31 and squeeze the tension spring 43, thereby exposing the probe 1 for use. After use, the anti-scratch sleeve 41 is released, and the tension spring 43 returns to its original position under its own elasticity, thereby pushing the anti-scratch sleeve 41 to wrap and protect the probe 1, preventing accidental scratches on the surface of the probe 1.

[0039] Because a certain force needs to be continuously applied to press the anti-scratch sleeve 41 into the protective shell 31 during use, which is inconvenient to operate, the device is also equipped with a locking component 44. The locking component 44 includes a compression spring 441 installed on the inner wall of the slot on the anti-scratch sleeve 41, and a locking slider 442 slidably connected to the inner wall of the slot is installed on the outer end of the compression spring 441. The protective shell 31 has a locking hole 443 that matches the locking slider 442. As the anti-scratch sleeve 41 slides into the protective shell 31, the locking slider 442 coincides with the locking hole 443 on the protective shell 31. At this time, the compression spring 441, which is continuously compressed in the slot on the anti-scratch sleeve 41, is extended and reset, thereby pushing the locking slider 442 into the locking hole 443, thus completing the locking of the anti-scratch sleeve 41. After the probe 1 is used, press the locking slider 442 to squeeze the compression spring 441 and slide it into the slot. Under the push of the tension spring 43, the anti-scratch sleeve 41 can automatically reset to protect the probe 1.
