Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a body restraint device for bronchoscopy. Background Technology

[0002] During bronchoscopy, body restraint devices (such as wrist / ankle restraints, head immobilizers, and trunk restraints) are often used to ensure operational safety and prevent patient discomfort or coughing from causing movement disturbances. However, existing restraint devices have several design and application defects in clinical practice, which may affect patient safety, comfort, and examination efficiency. Specifically, existing medical body restraint devices mainly use restraint straps to restrain the examiner's body. For example, Chinese utility model patent application number 202120124994.3 discloses a medical body restraint device, including: restraint straps and a fixing plate. There are two or more restraint straps, and each restraint strap has a first connecting part and a second connecting part, which are detachably connected. The fixing plate has a first perforation and a second perforation, which are spaced apart along the width of the fixing plate. Both the first and second perforations are used to thread the restraint straps to fix the patient's hands. This medical body restraint device uses restraint straps to restrain the examinee's body. Because the restraint straps have a certain degree of elasticity, the examinee can still make slight movements after the body is fixed. However, bronchoscopy requires inserting a thin endoscope into the airway through the mouth / nose. The operation path is deep and the space is narrow. Slight body movements may scratch the airway mucosa, which increases the difficulty of the doctor's operation. Summary of the Invention

[0003] The main objective of this invention is to provide a body restraint device for bronchoscopy, which aims to solve the problem that existing medical body restraint devices can still cause danger by allowing slight movement of the examinee's body after restraint.

[0004] To achieve the above objectives, the present invention provides a body restraint device for bronchoscopy, comprising a bed body having a bed board. Multiple sets of body clamping devices are arranged on the bed board, each set of body clamping devices being spaced apart along the length of the bed board. A through-type adjustment groove is provided at the location of the body clamping device on the bed board. The adjustment groove, in conjunction with the body clamping device, can accommodate the clamping of individuals of different body types. The body clamping device includes a frame fixed to the back of the bed board. A through-type first mating groove is provided on the frame from front to back, and a non-through-type second mating groove is provided on the frame from top to bottom. The first mating groove intersects and is perpendicular to the second mating groove. Sliding grooves are provided on both sides of the second mating groove. Moving blocks are symmetrically arranged in the second mating groove. Sliding blocks are provided on both sides of each moving block. The sliding blocks correspond one-to-one with the sliding grooves and are slidably arranged in the corresponding sliding grooves. The lower part of the moving block is located in the first mating groove. A driving block assembly is also provided in the first mating groove. The driving block assembly can drive the two moving blocks to move closer or further away at the same time. A clamping mechanism is provided on each moving block. The clamping mechanism is engaged in the adjustment groove and is used to clamp or release different parts of the human body. A head restraint mechanism is provided in the middle of one end of the bed board. The head restraint mechanism can restrain the examiner's head so that his head cannot move freely.

[0005] Optionally, a through-hole is provided at the center of the bottom of the frame, the through-hole leading to the first mating groove. The drive block assembly includes a drive screw, which is movably disposed within the adapter hole. A drive block is fixed to one end of the drive screw extending into the first mating groove. The side of the moving block facing the drive block is an inclined surface, and the inclined surface on the drive block contacts the inclined surface on the moving block, and the two are slidably engaged by a slider rail. A baffle is provided at the end of the drive screw, and a threaded sleeve is threadedly connected between the baffle on the drive screw and the frame. A drive mechanism is provided on the threaded sleeve.

[0006] Optionally, the drive mechanism includes a connecting block fixed to the bottom of the frame. The connecting block has a through shaft mating hole, and a drive shaft is rotatably disposed in the shaft mating hole. A first bevel gear is fixed to one end of the drive shaft near the threaded sleeve, and an operating handle is provided at the other end of the drive shaft away from the threaded sleeve. A second bevel gear is fixed to the threaded sleeve, and the second bevel gear meshes with the first bevel gear.

[0007] Optionally, the clamping mechanism includes a connecting rod, one end of which is fixed to the moving block, the connecting rod passes through the adjusting groove, and a clamping part is fixed to the other end of the connecting rod. The opposing surfaces of the two clamping parts are both set as arc-shaped surfaces.

[0008] Optionally, the clamping part is made of silicone.

[0009] Optionally, the head restraint mechanism includes a base pad, on which a first mounting groove and a second mounting groove are arranged side by side along the length direction. An optical shaft is fixed in the first mounting groove, and a screw is rotatably arranged in the second mounting groove. One end of the screw extends out of the base pad and is connected to a turntable. The screw has reverse threads from the middle to both ends. Two moving parts are arranged between the screw and the optical shaft. The two moving parts are respectively located on the reverse threads of the screw. Each moving part is provided with a limiting soft pad, and the opposing surfaces of the two limiting soft pads are set as arc-shaped surfaces.

[0010] Optionally, baffles are provided on opposite sides of both moving parts, and the baffles on one moving part are staggered from the baffles on the other moving part.

[0011] Optionally, cover plates are provided on the first and second mounting slots exposed on both sides.

[0012] Optionally, the first bevel gear and the second bevel gear are provided with a protective shell, which is fixed to the bottom of the frame.

[0013] Optionally, the device further includes a bracket connected to the back of the bed board for supporting the bed board, and the bottom of the bracket is provided with multiple casters.

[0014] This invention discloses a body restraint device for bronchoscopy. During use, the spacing of each set of body clamping devices is adjusted according to the examinee's body shape. The examinee then lies supine on the bed, with their head positioned at the head restraint mechanism for head fixation. Next, the drive block assemblies of each set of body clamping devices are activated sequentially. The drive block assembly moves within the first mating groove, causing two moving blocks to move synchronously towards each other along the second mating groove. The moving blocks maintain stability through sliding sliders on both sides within their grooves. This, in turn, causes the two clamping mechanisms to move closer synchronously along the adjustment groove until the corresponding body parts of the examinee are gently clamped, restricting unconscious body movements and facilitating the smooth conduct of the bronchoscopy. After the examination, the drive block assembly reverses its movement, causing the two moving blocks to move synchronously away, releasing the clamping mechanisms along the adjustment groove and allowing the examinee to be released from the bed. The entire adjustment and clamping process is simple to operate, highly adaptable, and effectively restricts the examinee's body movement, preventing body swaying during the examination and improving the safety and efficiency of bronchoscopy.

[0020] Please see Figures 1 to 7 This invention provides a body restraint device for bronchoscopy, which includes a bed 1 with a bed board 101. Multiple sets of body clamping devices 2 are provided on the bed board 101, with each set spaced apart along the length of the bed board 101. A through-type adjustment groove 102 is provided on the bed board 101 where the body clamping devices 2 are located. The adjustment groove 102, in conjunction with the body clamping devices 2, can accommodate the clamping of people of different body types. The body clamping device 2 includes a frame 201 fixed to the back of the bed board 101. A through-type first mating groove 202 is provided on the frame 201 from front to back, and a non-through-type second mating groove 203 is provided on the frame 201 from top to bottom. The first mating groove 202 and the second mating groove 203 intersect. Furthermore, vertically, both sides of the second mating groove 203 are provided with sliding grooves 204, and symmetrical moving blocks 205 are arranged in the second mating groove 203. Each moving block 205 is provided with a slider 206 on both sides. The slider 206 corresponds one-to-one with the sliding groove 204 and is slidably arranged in the corresponding sliding groove 204. The lower part of the moving block 205 is located in the first mating groove 202. The first mating groove 202 is also provided with a driving block assembly. The driving block assembly can drive the two moving blocks 205 to move closer or further away at the same time. Each moving block 205 is provided with a clamping mechanism 4. The clamping mechanism 4 is fitted in the adjusting groove 102 and is used to clamp or release different parts of the human body. A head restraint mechanism 5 is provided in the middle of one end of the bed board 101. The head restraint mechanism 5 can restrain the examiner's head so that his head cannot move freely.

[0021] In this embodiment, during use, the spacing of each set of body clamping devices 2 is adjusted according to the examinee's body shape. Then, the examinee lies flat on the bed board 101, with the head placed at the head restraint mechanism 5 to fix the head. Then, the drive block assembly of each set of body clamping devices 2 is activated in sequence. The drive block assembly moves in the first mating groove 202, driving the two moving blocks 205 to move synchronously towards each other along the second mating groove 203. The moving blocks 205 ensure movement stability by sliding the sliders 206 on both sides in the sliding groove 204, thereby driving the two clamping mechanisms 4 to move synchronously closer along the adjustment groove 102 until the corresponding body parts of the examinee are gently clamped, restricting the examinee's unconscious body movements and facilitating the smooth conduct of the bronchoscopy examination. After the examination is completed, the drive block assembly moves in the opposite direction, driving the two moving blocks 205 to move synchronously away from each other, causing the clamping mechanisms 4 to be released along the adjustment groove 102, thus releasing the examinee from the bed 1. The entire adjustment and clamping process is simple to operate, highly adaptable, and can stably restrict the examinee's body movement, avoiding body shaking during the examination and improving the safety and efficiency of bronchoscopy.

[0022] Please see Figure 3 , Figure 4 In some possible implementations, a through adapter hole 207 is provided at the bottom center of the frame 201, which leads to the first mating groove 202. The drive block assembly may include a drive screw 208, which is movably disposed in the adapter hole 207. A drive block 209 is fixed to one end of the drive screw 208 extending into the first mating groove 202. The side of the moving block 205 facing the drive block 209 is an inclined surface, and the side of the drive block 209 facing the moving block 205 is also an inclined surface. The inclined surface on the drive block 209 contacts the inclined surface on the moving block 205, and the two slide together through a slider rail. A baffle 210 is provided at the end of the drive screw 208. A threaded sleeve 211 is threadedly connected between the baffle 210 on the drive screw 208 and the frame 201. A drive mechanism 3 is provided on the threaded sleeve 211.

[0023] Rotating the threaded sleeve 211 causes it to rotate relative to the drive screw 208. During the rotation of the threaded sleeve 211, the distance between the baffle 210 and the frame 201 is changed, thereby pushing the drive screw 208 to move vertically along the adapter hole 207, causing the drive block 209 to move vertically within the first mating groove 202. When the drive block 209 moves vertically, the inclined surface acts on the two moving blocks 205 to move towards the center synchronously, or the inclined surface sliding fit allows the two moving blocks 205 to move away from the outside synchronously, thereby achieving precise control of the opening and closing state of the clamping mechanism 4.

[0024] Please see Figure 4In some embodiments, the drive mechanism 3 includes a connecting block 301, which is fixed to the bottom of the frame 201. A through shaft mating hole 302 is provided on the connecting block 301. A drive shaft 303 is rotatably disposed in the shaft mating hole 302. A first bevel gear 304 is fixed at one end of the drive shaft 303 near the threaded sleeve 211. An operating handle 305 is provided at the other end of the drive shaft 303 away from the threaded sleeve 211. A second bevel gear 306 is fixed on the threaded sleeve 211 and meshes with the first bevel gear 304.

[0025] Specifically, when it is necessary to clamp and fix the patient, the operator rotates the operating handle 305. The operating handle 305 drives the drive shaft 303 connected to it to rotate within the shaft mating hole 302 of the connecting block 301. The rotation of the drive shaft 303 synchronously drives the first bevel gear 304 fixed at its end to rotate. Since the first bevel gear 304 meshes with the second bevel gear 306 fixed on the threaded sleeve 211, the rotation of the first bevel gear 304 drives the second bevel gear 306 to rotate, which in turn drives the threaded sleeve 211 to rotate together. Under the action of the rotation of the threaded sleeve 211, the drive screw 208 connected to it by threads will move upward along the axial direction, thereby pushing the drive block 209 to move upward, and finally realizing the release action of the clamping mechanism 4 from the patient's body. When clamping is required, the operator rotates the operating handle 305 in the opposite direction. The drive shaft 303 drives the first bevel gear 304 to rotate in the opposite direction. Through the gear meshing relationship, the second bevel gear 306 and the threaded sleeve 211 rotate in the opposite direction. The drive screw 208 moves downward under the action of the thread, and the drive block 209 descends accordingly. The moving blocks 205 move closer together to clamp the patient's body. This design, which changes the direction of force transmission through bevel gear transmission, allows the operator to operate conveniently next to the frame, without having to perform complex operations directly above the patient's body, thus improving the convenience and safety of operation.

[0026] Please see Figure 1 , Figure 4 In some possible implementations, the clamping mechanism 4 includes a connecting rod 401, one end of which is fixed to the moving block 205. The connecting rod 401 passes through the adjusting groove 102, and a clamping part 402 is fixed to the other end of the connecting rod 401. The opposing surfaces of the two clamping parts 402 are both set as arc surfaces.

[0027] In this embodiment, the adjustment groove 102 provides space for the movement of the connecting rod 401, so that when the moving block 205 slides within the slide groove 204, the connecting rod 401 can drive the clamping part 402 to move synchronously above the bed board 101, thereby achieving clamping and releasing of the patient's body. The opposing surface of the clamping part 402 is designed as an arc-shaped surface, which conforms to the natural curves of human body parts (such as the waist, legs, etc.), allowing it to better fit the patient's body during clamping, increasing the contact area, dispersing the clamping force, and avoiding the excessive local pressure that may be caused by traditional planar clamping, which could lead to patient discomfort or pressure sores. For example, when the clamping part 402 acts on the patient's waist, the arc-shaped surface can wrap around both sides of the waist, providing a more stable and comfortable restraint effect.

[0028] Furthermore, in some embodiments, the clamping part 402 is made of silicone.

[0029] The clamping part 402 is made of silicone, which will not cause harm to the patient's body and can improve the patient's comfort during the examination.

[0030] Please see Figure 5 , Figure 6 In some possible implementations, the head restraint mechanism 5 includes a base pad 501. A first mounting groove 502 and a second mounting groove 503 are arranged side by side along the length direction on the base pad 501. An optical shaft 504 is fixed in the first mounting groove 502. A screw 505 is rotatably arranged in the second mounting groove 503. One end of the screw 505 extends out of the base pad 501 and is connected to a turntable 506. The screw 505 has reverse threads from the middle to both ends. Two moving parts 507 are arranged between the screw 505 and the optical shaft 504. The two moving parts 507 are respectively located on the reverse threads of the screw 505. Each moving part 507 is provided with a limiting soft pad 508. The opposing surfaces of the two limiting soft pads 508 are set as arc-shaped surfaces.

[0031] Specifically, when it is necessary to restrain the patient's head, the patient's head rests on the base pad 501, positioned between the two limiting pads 508. The operator rotates the turntable 506, which drives the screw 505 to rotate within the second mounting groove 503. Since the screw 505 has reverse threads from its center outwards, and two moving parts 507 are threaded onto the reverse threaded sections of the screw 505, and these moving parts 507 also slide against the optical axis 504, which guides and limits their movement to prevent rotation with the screw 505, when the screw 505 rotates, the two moving parts 507 will move linearly towards or away from each other along the axial direction of the screw 505. When the operator rotates the turntable 506 clockwise, the two moving parts 507 approach each other under the action of the reverse threads, causing the limiting pads 508 fixed on them to move synchronously until the limiting pads 508 gently contact the sides of the patient's head and apply a moderate restraining force, thereby stabilizing the patient's head on the base pad 501 and preventing it from swaying from side to side. When it is necessary to release the head restraint, the operator rotates the turntable 506 counterclockwise, the two moving parts 507 move away from each other, and the limiting pads 508 release their grip on the patient's head. The opposing surfaces of the limiting pads 508 are set as arc-shaped surfaces, which can better conform to the contour of the patient's head, improve the comfort and stability of the restraint, and their material is preferably soft and elastic sponge, which improves the patient's head comfort during the examination and reduces discomfort caused by prolonged restraint.

[0032] Please see Figure 6 , Figure 7 Each of the two movable parts 507 has a baffle 509 on one side opposite to the other movable part 507. The baffle 509 on one movable part 507 is staggered from the baffle 509 on the other movable part 507.

[0033] The baffle 509 enhances the safety of the device, ensuring smooth and accurate bronchoscopy. The staggered design of the two baffles 509 prevents interference during movement, guaranteeing the smooth movement of the moving part 507.

[0034] Please see Figure 5 In some embodiments, cover plates 510 are respectively provided on the first mounting groove 502 and the second mounting groove 503 exposed on both sides.

[0035] Specifically, the design of the cover plate 510 ensures the safety of the device on the one hand, and serves as a dustproof and waterproof function on the other.

[0036] Please see Figure 2 In some possible implementations, the first bevel gear 304 and the second bevel gear 306 are provided with a protective shell 307, which is fixed to the bottom of the frame 201.

[0037] In this embodiment, the protective shell 307 effectively prevents the first bevel gear 304 and the second bevel gear 306 from being exposed, thus providing dust and water protection and effectively extending the service life of the device.

[0038] Please see Figure 2 In some embodiments, the device further includes a bracket 6 connected to the back of the bed board 101 for supporting the bed board 101, and a plurality of casters 7 are provided at the bottom of the bracket 6.

[0039] Among them, the bracket 6 is an existing bed board bracket, which is sufficient to support the bed board 101. The multiple casters 7 are also a standard feature, designed to facilitate the movement of the device.

[0040] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural or procedural transformations made based on the description and drawings of the present invention, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
