Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a head protection and respiratory protection device for surgery. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials, and other similar or related items that are used directly or indirectly on the human body, including the necessary computer software. Medical devices include medical equipment and medical consumables.

[0003] In ultrasound-guided thyroid thermal ablation surgery, medical staff need to cover all parts of the body except the surgical site to prevent bacteria from spreading from the patient to the surgical site and increasing the probability of infection. Existing techniques use sterile drapes to cover the patient's body except the surgical site to prevent bacterial spread. However, when covering the head, the drape obstructs the medical staff's field of vision and the patient's respiratory field of vision, easily causing anxiety and tension in the patient due to limited vision and difficulty breathing. This prevents medical staff from constantly observing the patient's facial expressions and skin color to promptly identify and address potential problems and ensure the safety of the surgery. Therefore, this invention provides a head protection and respiratory support device for surgery to meet these needs. Summary of the Invention

[0004] The technical problem this invention aims to solve is to provide a head protection and breathing support device for surgery. This device utilizes a silicone sheet with ventilation holes made of highly transparent silicone material. The ventilation holes ensure airflow and prevent foreign objects from entering the device. The highly transparent silicone material possesses good flexibility and antibacterial properties, allowing it to conform to the patient's face for improved comfort while withstanding a certain amount of impact, thus protecting the patient's face. Simultaneously, the high transparency allows medical staff to easily observe the patient's facial expressions and breathing status, facilitating a smooth surgical procedure. This design addresses the problems of existing technologies that use sterile drapes to cover the patient's head, which obstructs the vision of both the patient and medical staff and hinders the patient's breathing.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A head protection and respiratory support device for surgery includes a device frame, a fixing component, a sealing component, and a mounting component. The sealing component and the fixing component are disposed inside the device frame. The sealing component is fixedly mounted on the bottom of the fixing component and connected to the device frame via the mounting component. The fixing component is connected to the device frame and the sealing component, and limits and fixes the device frame and the sealing component. The sealing component is connected to the device frame, the fixing component, and the mounting component.

[0007] The device frame includes a front plate, side plates are provided on both sides of the front plate, a rear plate is provided on the side of the side plate away from the front plate, and a first top plate and a second top plate are provided on the top of the front plate, side plates and rear plate.

[0008] Optionally, the fixing assembly includes a threaded rod, the outer wall of which is threadedly connected to a threaded cap. The threaded rod is fixedly connected to the top of the second top plate, and the threaded rod is inserted into the interior of the first top plate. The threaded cap is rotatably connected to the top of the first top plate. A plurality of elastic plates are provided between the first top plate and the second top plate. The plurality of elastic plates are slidably connected to the top of the second top plate. The plurality of elastic plates are respectively fixedly connected to the front plate, the side plate and the rear plate by screws.

[0009] Optionally, the sealing assembly includes a first sterile cloth fixedly connected to the end of the elastic plate away from the threaded cap, a first elastic cord and a second elastic cord inserted inside the first sterile cloth, a second sterile cloth, an elastic band and a third sterile cloth disposed inside the front plate, side plate and rear plate, and a fourth sterile cloth disposed at the bottom of the front plate, side plate and rear plate, with a third elastic cord inserted inside the fourth sterile cloth.

[0010] Optionally, the installation assembly includes a connecting piece, a limiting member, and a kit fixedly connected to the fourth sterile cloth. The connecting piece is fixedly connected to the rear plate by screws, and a locking block is fixedly connected to the top of the kit, the locking block being inserted into the bottom of the front plate.

[0011] Optionally, the side plate has a through groove inside, and a limiting groove is provided on one side of the side plate, with the limiting member inserted into the limiting groove.

[0012] Optionally, the outer walls of the second and third sterile drapes are fixedly connected with a first connector and a second connector, the elastic band is inserted into the interior of the second connector, and the two ends of the elastic band are respectively connected to the second and third sterile drapes.

[0013] Optionally, the front and rear panels have a first slot inside, and the front, side and rear panels have a second slot on top.

[0014] Optionally, the second and third sterile drapes are both snapped into corresponding first slots on the front and rear panels via connected first connectors, and the second and third sterile drapes are both inserted into through slots inside the side panels via connected second connectors. The elastic band is inserted into the through slots, and the first sterile drape and the first elastic cord are inserted into the second slots.

[0015] Optionally, a silicone sheet is fixedly connected to the inside of the front panel, an adhesive member is fixedly connected to one side of the silicone sheet, and an elastic sheet is fixedly connected to the side of the silicone sheet away from the adhesive member.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, the silicone sheet is made of highly transparent silicone with ventilation holes. The ventilation holes ensure air circulation and prevent foreign objects from entering the protective device. The highly transparent silicone material has good flexibility and antibacterial properties, which can not only fit the patient's face to improve comfort, but also withstand a certain impact to protect the patient's face. At the same time, the high transparency allows medical staff to observe the patient's facial expressions and breathing status at any time, which is conducive to the smooth operation of the surgery.

[0018] By setting up a fixing component, after medical staff rotate the threaded cap, the threaded cap will gradually screw onto or detach from the threaded rod through the threads. This causes the threaded cap and threaded rod to move the first and second top plates closer together or further apart. When the first and second top plates move closer together, they clamp and fix the elastic plate, allowing the device frame to be fixedly connected together through the elastic plate and locked in place. When the first and second top plates move further apart, they stop clamping and fixing the elastic plate, allowing deformation and displacement between the components of the device frame, facilitating subsequent adjustment of the size of the device frame.

[0019] By setting up a sealing component, when the overall size of the device frame is adjusted, the first, second, and third sterile cloths in the sealing component will seal the gaps created by the overall size adjustment, preventing bacteria from spreading to the outside and affecting the patient's surgery. Furthermore, when the device frame loses the fixation of the fixing component, the elastic force of the first elastic rope, second elastic rope, elastic band, and other elastic components in the sealing component will pull the device frame to retract and reset, thereby achieving the effect of automatically retracting and resetting the device frame.

[0020] By setting up sealing and limiting components, the fourth sterile cloth and the third elastic rope in the sealing component can cooperate with the limiting parts, kits, blocks and limiting grooves in the installation component to ensure that the gap between the bottom of the device and the patient's neck is sealed, ensuring the airtightness of the device, preventing bacteria from spreading to the surgical site and increasing the probability of infection at the patient's surgical site.

[0039] like Figures 1 to 9As shown, an embodiment of the present invention provides a head protection and respiratory support device for surgery, including a device frame, a fixing component, a sealing component, and an installation component. The device frame is made of lightweight, high-strength plastic. The sealing component and the fixing component are disposed inside the device frame. The sealing component is fixedly installed at the bottom of the fixing component and is connected to the device frame through the installation component. The fixing component is used to assist medical personnel in limiting and fixing the device frame and the sealing component, and is connected to the device frame and the sealing component. The sealing component is used to assist medical personnel in sealing the device frame, and is connected to the device frame, the fixing component, and the installation component.

[0040] In this embodiment, as Figures 1 to 5 As shown, the device frame includes a front plate 1, side plates 2 are provided on both sides of the front plate 1, a rear plate 3 is provided on the side of the side plate 2 away from the front plate 1, and a first top plate 4 and a second top plate 5 are provided on the top of the front plate 1, side plates 2 and rear plate 3. Figure 4 As shown, the fixing assembly includes a threaded rod 6, with a threaded cap 7 threadedly connected to the outer wall of the threaded rod 6. The threaded rod 6 is fixedly connected to the top of the second top plate 5 and inserted into the interior of the first top plate 4. The threaded cap 7 is rotatably connected to the top of the first top plate 4. Multiple elastic plates 8 are provided between the first top plate 4 and the second top plate 5. The multiple elastic plates 8 are slidably connected to the top of the second top plate 5 and are respectively fixedly connected to the front plate 1, the side plate 2, and the rear plate 3 by screws. By setting up the fixing assembly, after medical personnel rotate the threaded cap 7, the threaded cap 7 will gradually screw onto the threaded rod 6 or gradually detach from the threaded rod through the threads. 6. The threaded cap 7 and the threaded rod 6 respectively drive the first top plate 4 and the second top plate 5 to move closer or further apart. When the first top plate 4 and the second top plate 5 move closer together, they clamp and fix the elastic plate 8, allowing the front plate 1, side plate 2, and rear plate 3 to be fixedly connected to the first top plate 4 and the second top plate 5 through the elastic plate 8, thus locking and fixing the device frame. When the first top plate 4 and the second top plate 5 move further apart, they stop clamping and fixing the elastic plate 8, allowing the components of the device frame to deform and shift, facilitating subsequent adjustment of the size of the device frame.

[0041] In this embodiment, as Figures 4 to 8As shown, the sealing assembly includes a first sterile cloth 9 fixedly connected to the end of the elastic plate 8 away from the threaded cap 7. A first elastic cord 10 and a second elastic cord 11 are inserted inside the first sterile cloth 9. A second sterile cloth 12, an elastic band 13, and a third sterile cloth 14 are disposed inside the front plate 1, side plate 2, and rear plate 3. A fourth sterile cloth 15 is disposed at the bottom of the front plate 1, side plate 2, and rear plate 3. The first sterile cloth 9 and the fourth sterile cloth 15 are initially in a pleated state, gradually unfolding when pulled. A third elastic cord 16 is inserted inside the fourth sterile cloth 15. By setting the sealing assembly, the various parts of the device frame are moved away from each other. When the overall size of the device frame is adjusted, the distance between the first top plate 4, the second top plate 5, and the front plate 1, side plate 2, and rear plate 3 will pull the first elastic cord 10 and the second elastic cord 11 to deform and elongate synchronously, causing the first elastic cord 10 and the second elastic cord 11 to... 11 Pull the first sterile cloth 9 from the pleated state to the unfolded state, so that the first sterile cloth 9 seals the gaps created by the separation. As the front plate 1, side plate 2 and rear plate 3 move away from each other, the front plate 1 and rear plate 3 will pull the corresponding second sterile cloth 12 and third sterile cloth 14 to gradually detach from the through groove 21 inside the side plate 2 and pull the elastic band 13 to extend, sealing the gaps created by the separation. When the various parts of the device frame move away from each other, the first sterile cloth 9, the second sterile cloth 12 and the third sterile cloth 14 will seal the gaps created by the deformation, preventing bacteria from spreading to the outside and affecting the patient's surgery. When the device frame loses the fixation of the fixing components, the elastic force of the first elastic rope 10, the second elastic rope 11, the elastic band 13 and other elastic components in the sealing components will eventually pull the device frame to retract and retract, so as to achieve the effect of automatically retracting and retracting the device frame.

[0042] Furthermore, when sealing the gap between the bottom of the protective device and the patient's neck, the fourth sterile cloth 15 and the third elastic cord 16 in the sealing assembly can cooperate with the limiting member 18, the kit 19, the locking block 20, and the limiting groove 22 in the installation assembly. Medical staff place the space between the fourth sterile cloth 15 and the third elastic cord 16 around the patient's neck, so that the fourth sterile cloth 15 fits the patient's neck under the elastic action of the third elastic cord 16. Medical staff insert the limiting member 18 on the fourth sterile cloth 15 and the third elastic cord 16 into the limiting groove 22 on the outer wall of the side plate 2, and insert the locking block 20 on the kit 19 into the bottom of the front plate 1 to limit and fix the outer wall of the fourth sterile cloth 15 and the third elastic cord 16, so that the outer wall of the fourth sterile cloth 15 and the third elastic cord 16 fits against the bottom of the front plate 1, the side plate 2, and the rear plate 3, ensuring the sealing of the protective device and preventing bacteria from spreading to the surgical site and increasing the probability of infection at the patient's surgical site.

[0043] In this embodiment, as Figures 2 to 9As shown, the installation assembly includes a connecting piece 17, a limiting member 18, and a kit 19 fixedly connected to the fourth sterile cloth 15. The connecting piece 17, the limiting member 18, and the kit 19 are thin sheets of metal bent and fixed to the outer wall of the part where the fourth sterile cloth 15 connects to the third elastic rope 16. The connecting piece 17 is fixedly connected to the back plate 3 by screws. A locking block 20 is fixedly connected to the top of the kit 19. The locking block 20 is inserted into the bottom of the front plate 1. A through groove 21 is opened inside the side plate 2. A limiting groove 22 is opened on one side of the side plate 2. The limiting member 18 is inserted into the inside of the limiting groove 22. The outer walls of both the second sterile drape 12 and the third sterile drape 14 are fixedly connected to a first connector 23 and a second connector 24. Both the first connector 23 and the second connector 24 are thin metal sheets bent and fixed to the two long side outer walls of the second sterile drape 12 and the third sterile drape 14. An elastic band 13 is inserted into the second connector 24, and both ends of the elastic band 13 are connected to the second sterile drape 12 and the third sterile drape 14, respectively. Figure 9 As shown, the front panel 1 and the rear panel 3 have first slots 25 inside. The outer contour of the first connector 23 is slightly larger than the inner contour of the first slot 25, so that the first connector 23 and the first slot 25 are interlocked together by elastic deformation (interference fit). The top of the front panel 1, the side panel 2, and the rear panel 3 have second slots 26. The second sterile cloth 12 and the third sterile cloth 14 are both interlocked in the corresponding first slots 25 on the front panel 1 and the rear panel 3 by the connected first connectors 23. The second sterile cloth 12 and the third sterile cloth 14 are both inserted into the through groove 21 inside the side panel 2 by the connected second connectors 24. By matching the outer contour of the second connector 24 with the inner contour of the through groove 21, the second connector 24 will not produce gaps when sliding inside the through groove 21, ensuring a sealing effect. The elastic band 13 is inserted into the through groove 21. The first sterile cloth 9 and the first elastic cord 10 are inserted into the second slot 26. Due to the overall shape of the second slot 26 being narrow at the opening and wide at the bottom, and the enlarged shape of the connection between the first sterile cloth 9 and the first elastic cord 10, the first sterile cloth 9 and the first elastic cord 10 can slide into the second slot 26. The enlarged part of the connection between the first sterile cloth 9 and the first elastic cord 10 is inserted into the wide part of the second slot 26, and the first sterile cloth 9 is inserted into the narrow opening of the second slot 26. When the first sterile cloth 9 and the first elastic cord 10 are pulled, the enlarged part of the connection between the first sterile cloth 9 and the first elastic cord 10 will be blocked and limited by the narrow opening of the first sterile cloth 9, ensuring the stability of the connection between the first sterile cloth 9 and the first elastic cord 10 and the front plate 1, the side plate 2 and the rear plate 3. The first sterile cloth 9 and the first elastic cord 10 are not affected when sliding inside the second slot 26.

[0044] In this embodiment, as Figure 1 , Figure 2 and Figure 9As shown, a silicone sheet 27 is fixedly connected inside the front panel 1. The silicone sheet 27 has multiple ventilation holes to ensure airflow and prevent foreign objects from entering the protective device. The outer wall of the silicone sheet 27 is coated with an anti-fog coating to prevent fogging during patient breathing from obscuring the sheet and affecting the vision of both the patient and medical staff. A fitting piece 28 is fixedly connected to one side of the silicone sheet 27. Both the silicone sheet 27 and the fitting piece 28 are made of highly transparent silicone material, possessing good flexibility and antibacterial properties. This allows them to conform to the patient's face for improved comfort while also withstanding a certain amount of impact to protect the patient's face. The high transparency also facilitates... Medical staff can observe the patient's facial expressions and breathing status at any time, which is conducive to the smooth progress of the operation. The fitting 28 can fit the patient's mouth and nose, separating the patient's mouth and nose from the rest of the protective device. The silicone sheet 27 is fixedly connected to the elastic sheet 29 on the side away from the fitting 28. By setting the elastic sheet 29, medical staff can attach the breathing mask to the outside of the silicone sheet 27 through the elastic sheet 29 when needed, and cover the ventilation holes on the silicone sheet 27. This allows medical staff to supply oxygen and administer anesthesia to the patient through the curved mask ventilation holes and the fitting 28, which is conducive to meeting the needs of the operation.

[0045] The working principle of the technical solution provided by this invention is as follows: When a patient needs to undergo surgery, the protection device can first be adjusted to its maximum state and fixed by the fixing components (such as...). Figure 2 As shown), the protective device can be easily fitted onto the patient's head. Then, rotate the threaded cap 7 to stop the fixing component from securing the protective device. This allows the elastic components in the sealing component, such as the first elastic cord 10, the second elastic cord 11, and the elastic band 13, to return to their original elasticity and pull the protective device back into place until the device frame fits the patient's head. This allows the device frame to be adjusted to fit the patient's head, improving the device's versatility and adaptability. Medical staff can then re-fix the protective device using the fixing component to prevent the elastic components in the sealing component from returning to their original elasticity and pulling the device frame back into place, thus avoiding continuous pressure on the patient's head and affecting their experience. Finally, medical staff can place the fourth sterile cloth 15 and the third elastic cord 16 around the patient's neck, engage the limiting component 18 in the limiting groove 22, and engage the locking block 20 on the kit 19 at the bottom of the front panel 1 to seal the gap at the patient's neck, preventing bacterial spread and ensuring the protective device's airtightness.

[0046] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
