Description

Technical Field

[0001] This utility model belongs to the field of laser therapy instrument protection technology, and specifically relates to a multi-layered protective safety shielding device for laser therapy instruments. Background Technology

[0002] Laser therapy devices are typically based on the principles of selective absorption of light and thermal effects. The laser emits light waves of specific wavelengths that can penetrate the skin's surface and be absorbed by target chromophores such as melanin and hemoglobin within the skin. The absorbed light energy is converted into heat energy, which then destroys the target chromophores, such as melanocytes or dilated blood vessels, thereby achieving the therapeutic goal. The safety shielding device of the laser therapy device is a crucial component ensuring the safety of both the patient and the operator during laser treatment.

[0003] Publication No. "CN219071867U" discloses a handheld semiconductor laser therapy device, comprising a laser therapy device with a groove on its surface. A push button is slidably disposed within the groove. A support frame is fixedly connected to the symmetrical side of the groove. Multiple springs are fixedly connected to the support frame, and movable plates are fixedly connected to the multiple springs. The movable plates are connected to the push button via a transmission mechanism. This invention prevents the device from being dropped and damaged, thus protecting the laser therapy device.

[0004] Although the above-mentioned utility model can prevent the device from falling and being damaged, thus protecting the laser therapy device, the laser beam has the characteristics of high energy and high concentration, which can easily cause irreversible damage to the eyes, such as retinal burns and vision loss. Moreover, if the operator accidentally looks directly at the laser beam during use, even if it does not directly shine into the eyes, the scattered or reflected light may still cause damage to the eyes. Utility Model Content

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a multi-layer protective safety shielding device for laser therapy instruments, so as to solve the problem that the laser beam has the characteristics of high energy and high concentration, which can easily cause irreversible damage to the eyes, such as retinal burns and vision loss. Moreover, if the operator accidentally looks directly at the laser beam during use, even if it does not directly irradiate the eyes, the scattered or reflected light may still cause damage to the eyes.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A multi-layered protective safety shielding device for a laser therapy instrument includes a laser therapy head, a connecting wire fixedly connected to the bottom end of the laser therapy head, a first protective cover and a second protective cover symmetrically and movably connected to the outside of the laser therapy head, protective glass symmetrically and fixedly connected inside the first and second protective covers, and assembly blocks symmetrically and fixedly connected to both ends of the first protective cover, with fixing components installed inside the assembly blocks.

[0008] The fixing assembly includes a cavity, a second return spring, a movable plate, a push block, and a locking block. The cavity is located inside the assembly block. A second return spring is symmetrically fixed to one side of the cavity, and a movable plate is fixedly fixed to the other end of the second return spring. The movable plate is slidably connected to the cavity. A push block and a locking block are fixedly connected to the side of the movable plate away from the second return spring. The push block extends beyond the outer side of the first protective cover from the side away from the movable plate, and the locking block extends beyond the outer side of the assembly block from the side away from the movable plate. Assembly slots are symmetrically formed at both ends of the second protective cover. The assembly block is inserted into the assembly slot, and a locking groove is formed on one side of the assembly slot. The locking block is locked into the locking groove. This design prevents personnel from being exposed to laser radiation exceeding safety limits during laser therapy, protecting the operator's eyes and skin and avoiding injury caused by direct laser contact.

[0009] As a preferred technical solution, both the first and second protective covers are fixedly connected to positioning blocks on the side near the laser treatment head. Positioning grooves are symmetrically opened on the outer wall of the laser treatment head. The positioning blocks and positioning grooves are plugged in. The tight fit between the positioning blocks and positioning grooves ensures the accuracy of the protective cover's position after installation, preventing the protective cover from shifting or loosening during use, thereby ensuring the stability and safety of the laser treatment device.

[0010] As a preferred technical solution, the tops of the first and second protective covers are symmetrically fixedly connected with first limiting posts. The other end of the first limiting post has an internal hole, and the bottom of the internal hole is fixedly connected with a first reset spring. The other end of the first reset spring is fixedly connected with a second limiting post. The second limiting post is slidably connected to the inside of the internal hole. The other end of the second limiting post extends out of the first limiting post and is fixedly connected with a stop block. This prevents the laser treatment head from directly contacting the patient's skin during treatment, thereby reducing the potential risk of physical damage and protecting the patient's skin from harm.

[0011] As a preferred technical solution, the outer wall of the laser treatment head is symmetrically provided with mounting grooves, and a mounting base is movably connected inside the mounting groove. An anti-slip pad is glued to the other side of the mounting base. A magnetic suction groove is symmetrically provided at the bottom of the mounting groove. A magnetic block is symmetrically fixedly connected to one side of the mounting base. The magnetic block and the magnetic suction groove are magnetically connected, allowing users to periodically replace worn or contaminated pads, thereby keeping the laser treatment head clean and in good condition and extending the service life of the overall equipment.

[0012] As a preferred technical solution, the anti-slip mat has anti-slip textures on its surface and is made of soft rubber, which increases the friction between the hand and the laser treatment head, preventing the risk of slipping due to sweaty hands or a smooth surface of the laser treatment head, and ensuring the accuracy and safety of the treatment process.

[0013] In summary, the present invention has the following main advantages:

[0014] First, in this utility model, the first protective cover is attached to the outer wall of the laser treatment head, the positioning block is inserted into the positioning groove, and then the button is pressed, causing the moving plate to move the locking block. The moving plate presses against the second reset spring, and the locking block retracts into the cavity. Then the second protective cover is attached to the outer wall of the laser treatment head, and the assembly block is inserted into the assembly groove. The button is released, the second reset spring is reset, the moving plate rebounds and causes the locking block to pop out, and the locking block engages with the slot. This can prevent personnel from being exposed to laser radiation exceeding the safety limit during the operation of the laser treatment device, protect the operator's eyes and skin, and avoid injury caused by direct contact with the laser.

[0015] Secondly, in this invention, the first and second protective covers are installed on the outer wall of the laser treatment head. When the laser treatment device is turned on, the operator holds the laser treatment head and brings the stop block into contact with the patient's skin. The stop block drives the second limiting post to slide inside the built-in hole of the first limiting post. The second limiting post presses against the first return spring, which is then compressed. The laser treatment head treats the patient, and the operator observes the treatment through the protective glass inside the first and second protective covers. This avoids direct contact between the laser treatment head and the patient's skin during treatment, thereby reducing the potential risk of physical damage and protecting the patient's skin from harm.
