Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and specifically relates to an anesthetic device with an adjustable headrest. Background Art

[0002] During clinical operations such as surgeries or intubations on patients, anesthesia is often required. This operation involves injecting anesthetic drugs into the corresponding positions while the patient is conscious, temporarily blocking the sensory nerve conduction function of the patient's body or a certain part of the body, while keeping the motor nerve conduction intact or having a certain degree of blockage. This blockage is completely reversible and does not cause any damage to the patient's body tissues. In this state, the pain sensation experienced by the patient during the surgery can be reduced, and the patient will not move violently due to pain, creating good conditions for the surgery to proceed, thus facilitating the doctor to perform the surgery or intubation smoothly and reducing the difficulty of the surgery or intubation.

[0003] Publication No. CN115607241A discloses an anesthetic-assisted puncture device. The servo motor drives the connecting sleeve to rotate, the connecting sleeve drives the sliding sleeve to move horizontally, and then drives the anesthetic puncture needle to move horizontally to perform anesthetic puncture at the puncture point of the patient. When the protruding column touches the limit switch on the slider during the puncture process, the limit switch will give a signal to the servo motor, and the servo motor stops rotating, thereby preventing the anesthetic puncture needle from moving horizontally further and restricting the insertion depth of the puncture needle. This avoids the anesthetic puncture needle from penetrating too deep due to external interference and slow sensory response when the doctor performs manual puncture, which may cause damage to the nerves in the patient's spine. However, the following problems still exist in the actual use of this patent: Although this anesthetic-assisted puncture device drives the connecting sleeve to rotate through the servo motor, the connecting sleeve drives the sliding sleeve to move horizontally, and then drives the anesthetic puncture needle to move horizontally to perform anesthetic puncture at the puncture point of the patient, it is not convenient to fix the patient's head during anesthesia, resulting in head shaking, which affects the efficiency of patient anesthesia. At the same time, the patient needs a period of waking time during the surgery, and nausea and vomiting may occur during this process. If the patient's head cannot be turned to the side in time, the vomit cannot be discharged, leading to danger.

[0004] Therefore, an anesthetic device with an adjustable headrest is proposed to solve the problems mentioned above. Summary of the Invention

The specific content is as follows: 1. By setting the head fixing mechanism, not only can the rotating plate and the head support plate at the top of the fixed pillow be used to support the patient's head, avoiding the shaking of the patient's head and thus affecting the anesthetic effect. By rotating the adjustment knob to drive the adjustment screw rod to rotate, the adjustment thread sleeve drives the support fixing rod and the head support plate to move, and the distance between the two head support plates can be adjusted to adapt to patients with different head sizes. Through the sliding connection between the adjustment sliding rod inside the support fixing rod and the adjustment sliding sleeve, and under the elastic force of the adjustment spring, the rotation of the adjustment support rod is realized, facilitating the support and limitation of the patient's head through the head support plate. When there is a wound behind the patient's head, the rotating plate can be opened through the connecting hinge, the head support plate can support the rotating plate, and the through groove can make the patient's head hollow, avoiding the phenomenon that the posterior brain part cannot be anesthetized due to injury. At the same time, the limit plate can be used to support the patient's side face. When the patient wakes up after surgery and vomits due to the effect of anesthetic, the side face can be rotated to drive the limit plate and the connecting bracket to rotate, unfold the protective bag, so that the vomit can smoothly fall into the collection box at the bottom through the through groove for collection, avoiding the contamination of the operating bed by vomit. The neck support can support the patient's neck, improve the comfort of the head. At the same time, by rotating the fixing knob to drive the fixing screw rod to rotate, the fixing screw rod moves inside the sliding sleeve. When the conical block squeezes the conical sleeve and the clamping pin expands, using the clamping connection between the clamping pin and the fixed pillow, the neck support can be fixed. When the clamping pin is separated from the fixed pillow, the fixed block can be pulled to drive the sliding sleeve to slide inside the fixed pillow, and the position of the neck support can be adjusted to facilitate the support of the necks of patients with different heights. By starting the tilt motor to drive the first sprocket transmission component and the tilt screw rod to rotate, the tilt thread sleeve moves outside the tilt screw rod and drives the tilt rotating rod to rotate. Under the action of the rotating support, the tilt bed board rotates, facilitating the support of the patient's back; 2. By setting up the lifting storage mechanism, not only can the second sprocket drive assembly and the lifting bidirectional threaded rod be driven to rotate by turning the lifting handle, so that while the lifting thread sleeve moves relatively, the lifting rotating rod is driven to rotate, and while the lifting sliding sleeve slides relatively on the outside of the lifting sliding rod, the distance between the lifting bottom plate and the lifting top plate can be adjusted, the height adjustment of the inclined bed plate and the fixed bed plate can be realized, which is suitable for medical staff of different heights to perform operations, and at the same time it is convenient for patients of different heights to lie on the inclined bed plate and the fixed bed plate. By the feature that the translation sliding sleeve is slidably connected with the translation sliding rod, the storage bracket can be moved out from the top of the lifting bottom plate. By stepping on the ejection button, the bidirectional rack is driven to descend, and at the same time, by the feature of the meshing connection between the bidirectional rack, the meshing gear and the meshing rack, while the meshing rack drives the ejection plate to move up and down, the storage box can be ejected from the inside of the storage bracket, which is convenient for medical staff to take the medical devices and supplies stored in the storage box. The disinfection equipment is arranged at the bottom of the lifting top plate, which can disinfect the medical supplies and improve the safety of the medical supplies.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-11, the present invention provides a technical solution: a headrest-adjustable anesthesia device, including a head fixing mechanism 1, an inclined base 128 and a fixing bracket 139 installed at the bottom of the head fixing mechanism 1. A lifting storage mechanism 2 is provided at the bottom of the head fixing mechanism 1, and a storage bracket 214 is arranged inside the lifting storage mechanism 2. The head fixing mechanism 1 includes a fixed pillow 101. A through groove 102 is opened at the central position inside the fixed pillow 101. Connecting hinges 103 are symmetrically installed on both sides of the fixed pillow 101 close to the through groove 102. A rotating plate 104 is rotatably connected to the tops of the two connecting hinges 103. Among them, adjusting brackets 105 are symmetrically installed on the tops of the two rotating plates 104. One end of the adjusting bracket 105 is rotatably connected to an adjusting knob 106. An adjusting threaded rod 107 is fixedly installed at the end of the adjusting knob 106. Among them, an adjusting threaded sleeve 108 is threadedly connected to the outside of the adjusting threaded rod 107. A support fixing rod 109 is fixedly installed at the top of the adjusting threaded sleeve 108. An adjusting sliding rod 110 is fixedly installed inside the support fixing rod 109. An adjusting sliding sleeve 111 is slidably connected to the outside of the adjusting sliding rod 110. An adjusting spring 112 is fixedly installed at the bottom of the adjusting sliding sleeve 111. An adjusting support rod 113 is rotatably connected to the outside of the adjusting sliding sleeve 111. The end of the adjusting support rod 113 is rotatably connected to a head support plate 114. The rotating plate 104 and the head support plate 114 on the top of the fixed pillow 101 are used to support the patient's head, avoiding the shaking of the patient's head and thus affecting the anesthesia effect. By rotating the adjusting knob 106 to drive the rotation of the adjusting threaded rod 107, the adjusting threaded sleeve 108 drives the support fixing rod 109 and the head support plate 114 to move, and the distance between the two head support plates 114 can be adjusted to adapt to patients with different head sizes. Due to the feature that the adjusting sliding rod 110 inside the support fixing rod 109 is slidably connected to the adjusting sliding sleeve 111 and under the elastic force of the adjusting spring 112, the rotation of the adjusting support rod 113 is realized, facilitating the support and limitation of the patient's head through the head support plate 114.

[0020] Symmetrically fixed to the bottom of each of the two rotating plates 104 are connecting brackets 115. The end of the connecting bracket 115 is rotatably connected to a connecting rotating rod 116. One end of the connecting rotating rod 116 is fixedly installed with a protective bag 117, and the end of the connecting rotating rod 116 away from the protective bag 117 is fixedly installed with a limiting plate 118. When there is a wound on the back of the patient's head, the rotating plate 104 can be opened through the connecting hinge 103. The rotating plate 104 can be supported by the head support plate 114, and the patient's head can be hollowed out through the through groove 102 to avoid the phenomenon that the back of the head cannot be anesthetized due to injury. At the same time, the limiting plate 118 can be used to support the patient's side face. When the patient wakes up after the operation and vomits due to the effect of the anesthetic, the side face can be rotated to drive the limiting plate 118 and the connecting bracket 115 to rotate, and the protective bag 117 can be unfolded, so that the vomit can smoothly fall into the collection box 138 at the bottom through the through groove 102 for collection, avoiding the contamination of the operating bed by the vomit.

[0021] Symmetrically and slidably connected to the inner sides of both sides of the fixed pillow 101 are sliding sleeves 119. Fixed to the ends of both of the two sliding sleeves 119 are fixing blocks 120. A neck support 121 is fixedly installed between the two fixing blocks 120. Rotatably connected to the outer sides of both of the two fixing blocks 120 are fixing knobs 122. Threadedly connected to the end of the fixing knob 122 is a fixing threaded rod 123. Fixed to the end of the fixing threaded rod 123 is a tapered block 124. Fixed springs 125 are fixedly installed around the inner part of the sliding sleeve 119 near the tapered block 124. Fixed to the bottom of the fixed spring 125 is a tapered sleeve 126. Fixedly installed inside the tapered sleeve 126 near the fixed spring 125 is a clamping pin 127. An inclined base 128 is fixedly installed at the bottom of the fixed pillow 101. The neck support 121 can support the patient's neck to improve the comfort of the head. At the same time, by rotating the fixing knob 122 to drive the fixing threaded rod 123 to rotate, the fixing threaded rod 123 moves inside the sliding sleeve 119. When the tapered block 124 squeezes the tapered sleeve 126 to make the clamping pin 127 expand, the clamping pin 127 can be used to fixedly connect with the fixed pillow 101 to fix the neck support 121. When the clamping pin 127 is separated from the fixed pillow 101, the fixing block 120 can be pulled to drive the sliding sleeve 119 to slide inside the fixed pillow 101, and the position of the neck support 121 can be adjusted to facilitate the support of the necks of patients of different heights.

[0022] One end of the inclined base 128 is fixedly installed with a motor cover 129. On one side inside the motor cover 129, an inclined motor 130 is fixedly installed. The output end of the inclined motor 130 is fixedly connected to a first sprocket drive assembly 131. On one side of the first sprocket drive assembly 131, inclined threaded rods 132 are symmetrically connected. Threaded sleeves 133 are threadedly connected to the outer sides of the two inclined threaded rods 132. The top of the inclined threaded sleeve 133 is rotatably connected to an inclined rotating rod 134. The tops of the two inclined rotating rods 134 are rotatably connected to an inclined bedplate 135. On one side of the top of the inclined base 128, rotating supports 136 are symmetrically installed. On the side of the inclined base 128 away from the rotating support 136, support blocks 137 are symmetrically installed. A collection box 138 is arranged at the bottom of the inclined base 128 close to the fixed pillow 101. The top of the fixed bracket 139 is fixedly installed with a fixed bedplate 140. By starting the inclined motor 130 to drive the first sprocket drive assembly 131 and the inclined threaded rods 132 to rotate, the inclined threaded sleeve 133 moves on the outer side of the inclined threaded rod 132 while driving the inclined rotating rod 134 to rotate. Under the action of the rotating support 136, the rotation of the inclined bedplate 135 is realized, which is convenient for supporting the patient's back.

[0023] The lifting and storage mechanism 2 includes a lifting top plate 201. The lifting top plate 201 is fixedly installed at the bottom of the inclined base 128 and the fixed bracket 139. Protective covers 202 are fixedly installed on both sides of the lifting top plate 201. Inside the protective covers 202, second sprocket drive assemblies 203 are rotatably connected. On the outer side of one second sprocket drive assembly 203, a lifting rotating handle 204 is fixedly installed. A lifting double-threaded rod 205 is symmetrically installed between the two second sprocket drive assemblies 203. At both ends of the lifting double-threaded rod 205, lifting threaded sleeves 206 are symmetrically threadedly connected. The bottom of the lifting threaded sleeve 206 is rotatably connected to a lifting rotating rod 207. The bottom of the lifting rotating rod 207 is rotatably connected to a lifting sliding sleeve 208. Inside the lifting sliding sleeve 208, a lifting sliding rod 209 is slidably connected. A lifting bottom plate 210 is fixedly installed on the outer side of the lifting sliding rod 209. Universal wheels 211 are fixedly installed around the bottom of the lifting bottom plate 210. By using the lifting rotating handle 204 to drive the second sprocket drive assembly 203 and the lifting double-threaded rod 205 to rotate, the lifting threaded sleeves 206 move relative to each other while driving the lifting rotating rod 207 to rotate, so that the lifting sliding sleeve 208 slides relative to the outer side of the lifting sliding rod 209 while adjusting the distance between the lifting bottom plate 210 and the lifting top plate 201, which can realize the height adjustment of the inclined bedplate 135 and the fixed bedplate 140, adapt to medical staff of different heights for surgery, and at the same time facilitate patients of different heights to lie on the inclined bedplate 135 and the fixed bedplate 140.

[0024] Inside the lifting bottom plate 210, translation sliding rods 212 are symmetrically installed. On the outer sides of the two translation sliding rods 212, translation sliding sleeves 213 are symmetrically installed. The storage bracket 214 is fixedly installed on the top of the translation sliding sleeve 213. On both sides of the storage bracket 214, ejection buttons 215 are slidably connected. The end of the ejection button 215 is fixedly connected to a bidirectional rack 216. On both sides of the bottom of the bidirectional rack 216, meshing gears 217 are meshed. The meshing gears 217 are rotatably connected to the storage bracket 214. On the outer sides of the two meshing gears 217, meshing racks 218 are meshed. At the bottoms of the roller meshing racks 218, ejection plates 219 are fixedly installed. On the top of the ejection plate 219, a storage box 220 is placed. Due to the feature that the translation sliding sleeve 213 is slidably connected to the translation sliding rod 212, the storage bracket 214 can be moved out from the top of the lifting bottom plate 210. By stepping on the ejection button 215 to drive the bidirectional rack 216 to descend, and at the same time using the meshing connection characteristics among the bidirectional rack 216, the meshing gears 217, and the meshing racks 218, while the meshing rack 218 drives the ejection plate 219 to move up and down, the storage box 220 can be ejected from the inside of the storage bracket 214, facilitating medical staff to take the medical devices and supplies stored in the storage box 220. A disinfection device is provided at the bottom of the lifting top plate 201, which can disinfect medical supplies and improve the safety of medical supplies.

[0025] Working principle: Before using this adjustable headrest anesthetic device, it is necessary to first check the overall condition of the device to ensure that it can work normally. According to Figure 1 - Figure 11 As shown, first, use the lifting rotating handle 204 to drive the second sprocket transmission assembly 203 and the lifting bidirectional threaded rod 205 to rotate, so that while the lifting threaded sleeve 206 moves relatively, it drives the lifting rotating rod 207 to rotate, and while the lifting sliding sleeve 208 slides relatively on the outer side of the lifting sliding rod 209, the distance between the lifting bottom plate 210 and the lifting top plate 201 is adjusted, enabling the height adjustment of the inclined bed plate 135 and the fixed bed plate 140, adapting to medical staff of different heights for surgery, and at the same time facilitating patients of different heights to lie on the inclined bed plate 135 and the fixed bed plate 140. Due to the feature that the translation sliding sleeve 213 is slidably connected to the translation sliding rod 212, the storage bracket 214 can be moved out from the top of the lifting bottom plate 210. By stepping on the ejection button 215 to drive the bidirectional rack 216 to descend, and at the same time using the meshing connection characteristics among the bidirectional rack 216, the meshing gears 217, and the meshing racks 218, while the meshing rack 218 drives the ejection plate 219 to move up and down, the storage box 220 can be ejected from the inside of the storage bracket 214, facilitating medical staff to take the medical devices and supplies stored in the storage box 220. A disinfection device is provided at the bottom of the lifting top plate 201, which can disinfect medical supplies and improve the safety of medical supplies.

[0026] Secondly, the rotating plate 104 at the top of the fixed pillow 101 and the head support plate 114 are used to support the patient's head, preventing the patient's head from shaking and thus affecting the anesthesia effect. By rotating the adjustment knob 106, the adjustment threaded rod 107 is driven to rotate, so that the adjustment threaded sleeve 108 drives the support fixing rod 109 and the head support plate 114 to move, and the distance between the two head support plates 114 can be adjusted to adapt to patients with different head sizes. Due to the sliding connection between the adjustment sliding rod 110 inside the support fixing rod 109 and the adjustment sliding sleeve 111, and under the elastic force of the adjustment spring 112, the rotation of the adjustment support rod 113 is realized, which is convenient for supporting and limiting the patient's head through the head support plate 114. When there is a wound on the back of the patient's head, the rotating plate 104 can be opened through the connecting hinge 103. The head support plate 114 can support the rotating plate 104, and the through groove 102 enables the patient's head to be hollowed out, avoiding the phenomenon that the back of the head cannot be anesthetized due to injury. At the same time, the limiting plate 118 can support the patient's side face. When the patient wakes up after the operation and vomits due to the effect of the anesthetic, the limiting plate 118 and the connecting bracket 115 can be driven to rotate by rotating the side face, and the protective bag 117 is unfolded, so that the vomit can smoothly fall into the collection box 138 at the bottom through the through groove 102 for collection, avoiding the vomit from contaminating the operating table.

[0027] Finally, the neck support 121 can support the patient's neck, improving the comfort of the head. At the same time, by rotating the fixing knob 122, the fixing threaded rod 123 is driven to rotate, and the fixing threaded rod 123 moves inside the sliding sleeve 119. When the conical block 124 squeezes the conical sleeve 126 to expand the engaging plug 127, due to the engaging connection between the engaging plug 127 and the fixed pillow 101, the neck support 121 can be fixed. When the engaging plug 127 is separated from the fixed pillow 101, the fixed block 120 can be pulled to drive the sliding sleeve 119 to slide inside the fixed pillow 101, and the position of the neck support 121 can be adjusted to facilitate the support of the necks of patients with different heights.
