Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to an anesthesia care neck support device. Background Art

[0002] In modern medical surgery, general anesthesia is a common method of anesthesia, especially when facing more serious diseases or certain surgical scenarios that are not suitable for local anesthesia. General anesthesia can provide the necessary conditions for the smooth progress of the operation.

[0003] However, after general anesthesia, patients will enter a period of unconscious recovery. During this period, due to the effects of anesthetic drugs, the patient's body functions are significantly weakened; among them, the respiratory system is more prominently affected, and problems such as difficulty breathing often occur; this unstable respiratory condition will pose a potential threat to the patient's life safety.

[0004] In order to effectively deal with this risk and ensure the safety of patients during the anesthesia recovery period, a head and neck support device is usually used to reasonably fix the patient's head and neck to ensure that the patient can breathe normally. In the related technology, for example, Chinese patent CN218338663U discloses a head, neck and shoulder pillow for anesthesia surgery. During use, the head, neck and shoulder pillow for anesthesia surgery drives the driving shaft to rotate by rotating the first hand wheel clockwise, and the driving shaft drives the toggle gear to rotate, and the toggle gear is meshed with the cylindrical rack, so that the cylindrical rack is toggled and slides up under the guidance of the guide block, and the cylindrical gear is used to rotate. The strip drives the adjusting push plate to complete the synchronous rise, and the rise of the adjusting push plate is used to derive the pillowcase to follow the displacement, so as to form a height adjustment for the shoulder support position; at the same time, the second hand wheel is rotated clockwise to drive the threaded rod to complete the rotation, and the threaded connection between the threaded rod and the carrying frame and the threaded rod and the head circle pillow seat is used to derive the displacement of the first force-bearing push block and the second force-bearing push block during the process of being driven to rotate. The first force-bearing push block and the second force-bearing push block are driven by the threaded rod to slide and displace at the bare rod, thereby driving the first folding rod and the second folding rod to fold and rise, and deriving the lifting push frame to drive the head circle main body to rise to a suitable position, and the placement groove is used to place the ears in the side-lying position.

[0005] Although the above-mentioned head, neck and shoulder pillow for anesthesia surgery can support the patient's head and neck, it is found in actual use that when adjusting the height of the shoulder support position and the height of the head circle body, multiple mechanisms need to be linked, which is not only troublesome to operate, but also requires multiple manual adjustments. Moreover, communication with the patient is required after each adjustment, which delays the timing of the surgical operation; and because the patient's head is not fixed, when the patient turns his head unconsciously, it may cause breathing difficulties, which may easily endanger the patient's life safety. Summary of the invention

[0006] Based on this, it is necessary to provide an anesthetic care neck support device for the problems of troublesome operation and lack of fixation of the patient's head during the use of the current neck support device, which is likely to endanger the patient's life safety.

[0007] The above object is achieved by the following technical solutions:

[0010] Further, an adjusting mechanism is also arranged on the base. The adjusting mechanism is configured to fix the position of the head fixing structure when the clamping force of the two head fixing structures on the patient's head is equal to a preset value.

[0011] Further, the adjusting mechanism includes two first rotating shafts, two second rotating shafts, an open rotating ring, an open fixed ring, a rack, a gear, a first bevel gear, a second bevel gear, and a transmission component.

[0012] Further, the transmission component includes a first magnetic block and a second magnetic block. The first magnetic block is inserted into the second rotating shaft. The second magnetic block is inserted into the open rotating ring and is magnetically connected to the first magnetic block.

[0013] Further, an adaptation mechanism is further arranged on the machine base. The adaptation mechanism is configured to enable the first piston rod to slide in the first hydraulic cylinder body after the position of the head fixing structure is fixed.

[0014] Further, the adaptation mechanism includes a sliding plate and a third hydraulic cylinder body. The third hydraulic cylinder body is communicated with the first hydraulic cylinder body. The sliding plate is elastically slidably inserted into the third hydraulic cylinder body.

[0015] Further, a clamping mechanism is further arranged on the machine base. The clamping mechanism is configured to fix the position of the neck support structure when the clamping force of the two head fixing structures on the patient's head is equal to a preset value.

[0016] Further, the clamping mechanism includes a first comb tooth part, two wedge parts, and two sliders. The first comb tooth part is arranged on the neck support structure.

[0020] Furthermore, by providing an adjustment mechanism, during the use process, when the clamping force of the two head fixing structures on the patient's head is equal to a preset value, the position of the head fixing structure can be fixed through the adjustment mechanism, so as to ensure that patients of any body type receive the same clamping force. On the one hand, it avoids damage caused by excessive clamping force, and on the other hand, it avoids the inability to provide protection due to too small clamping force, which is beneficial to improving the versatility.

[0021] Furthermore, by providing a clamping mechanism, during the use process, when the clamping force of the two head fixing structures on the patient's head is equal to a preset value, the position of the neck support structure is fixed through the clamping mechanism, improving the stability of the neck support mechanism when supporting the patient's neck.

[0046] As Figures 1 to 10 shown, the anesthetic care neck support device provided by the embodiment of the present invention is used to support the head and neck of a patient, and is configured to include a base 1, on which a neck support structure 2, a head support structure 3, a transmission mechanism 4 and two sliding seats 5 are provided. The neck support structure 2 can elastically slide in the vertical direction and is configured to support the patient's neck; the head support structure 3 can elastically slide in the vertical direction and is configured to support the patient's head; the two sliding seats 5 are symmetrically arranged, and the sliding seat 5 can slide in a direction closer to or farther from the other sliding seat 5; the transmission mechanism 4 is configured to be able to transmit the movement of the head support structure 3 to the two sliding seats 5 to drive the two sliding seats 5 to slide synchronously in a direction approaching or separating from each other; a head fixing structure 6 is provided on each sliding seat 5, and the two head fixing structures 6 can elastically slide synchronously in a direction approaching or separating from each other and are configured to be able to fix the patient's head.

[0047] Specifically in this embodiment, as Figure 7 shown, the machine base 1 is set as a rectangular plate-like structure, and has a length direction and a width direction that are vertically arranged; as Figure 1 shown, the neck support structure 2 is set as a cuboid-like block structure, and when installed, the length direction is parallel to the length direction of the machine base 1, and it is arranged on the top of the machine base 1; as Figure 6 shown, the head support structure 3 is set as a cuboid-like block structure, and when installed, the length direction is parallel to the length direction of the machine base 1, and it is arranged on the top of the machine base 1.

[0048] It can be understood that the machine base 1 can be installed on the top of the bed board and is located at the end.

[0049] To facilitate the elastic sliding of the neck support structure 2 and the head support structure 3, as Figure 7 shown, two first mounting rings 11 and four second mounting rings 12 are provided on the top of the machine base 1. Among them, the two first mounting rings 11 are arranged at intervals along the length direction of the machine base 1. The four second mounting rings 12 are evenly divided into two groups. The two groups of second mounting rings 12 are arranged at intervals along the width direction of the machine base 1. The two second mounting rings 12 in the same group are arranged at intervals along the length direction of the machine base 1, and are respectively in the same column as the two first mounting rings 11. A first compression spring is inserted into each first mounting ring 11, and a second compression spring is inserted into each second mounting ring 12; two first mounting posts are provided at the bottom of the neck support structure 2. The two first mounting posts are respectively slidably inserted into the two first mounting rings 11 and are fixedly connected to the first compression spring to realize the elastic sliding of the neck support structure 2 in the vertical direction; four second mounting posts are provided at the bottom of the head support structure 3. The four second mounting posts are respectively slidably inserted into the four second mounting rings 12 and are fixedly connected to the second compression spring to realize the elastic sliding of the head support structure 3 in the vertical direction.

[0050] To facilitate improving the patient experience, the top surface of the neck support structure 2 and the top surface of the head support structure 3 can both be set as concave arc surfaces to adapt to the shape of the patient's neck and head.

[0051] As Figure 1 shown, the sliding seat 5 is set as a plate-like structure and is vertically installed on the top of the machine base 1. The plate surface of the sliding seat 5 is parallel to the width direction of the machine base 1. The two sliding seats 5 are arranged at intervals along the length direction of the machine base 1; to facilitate the sliding seat 5 to slide in the direction of approaching or moving away from the other sliding seat 5, as Figure 7As shown, two first sliding grooves 101 are formed at the top of the machine base 1. The first sliding grooves 101 extend along the length direction of the machine base 1, are arranged between two groups of second mounting rings 12, and are located outside the second mounting rings 12. The two first sliding grooves 101 are arranged at intervals along the length direction of the machine base 1. When the sliding seat 5 is installed, the bottom of it is slidably inserted into the first sliding grooves 101.

[0052] As Figure 6 shown, the head fixing structure 6 is arranged as a strip-shaped block structure; as Figure 1 shown, the head fixing structure 6 extends along the width direction of the machine base 1 during installation; to facilitate the realization that the two head fixing structures 6 can elastically slide synchronously in the directions of approaching each other or moving away from each other, as Figure 1 and Figure 8 shown, two third mounting rings 51 are arranged on the inner side plate surface of the sliding seat 5. The two third mounting rings 51 are arranged at intervals along the width direction of the sliding seat 5. A third compression spring is inserted into each of the third mounting rings 51. The third mounting rings 51 are arranged near the top of the sliding seat 5. Two third mounting posts are arranged on the outer strip surface of the head fixing structure 6. The two third mounting posts are respectively slidably inserted into the two third mounting rings 51 and are fixedly connected to the third compression springs to realize the elastic sliding of the head fixing structure 6.

[0053] During the use process, first, let the patient sit on the bed board, and then lie flat on the bed board with the face up and the back down, and the head facing the machine base 1; during the process of the patient lying flat, when the patient's head and neck fall on the neck support structure 2 and the head support structure 3, under the action of gravity, the patient's head and neck can simultaneously press down the neck support structure 2 and the head support structure 3, and while compressing the first compression spring and the second compression spring, press down the neck support structure 2 and the head support structure 3 to a proper position, so as to realize the automatic and reasonable support for the patient's head and neck; during the movement of the head support structure 3, under the action of the transmission mechanism 4, the two sliding seats 5 slide synchronously along the first sliding grooves 101 in the direction of approaching each other. When the head fixing structure 6 contacts the patient's head, as the sliding seat 5 continues to move, the two head fixing structures 6 move synchronously in the direction of moving away from each other under the pushing of the patient's head, and while compressing the third compression spring, clamp the patient's head to ensure that the patient will not turn the head unconsciously and avoid causing breathing difficulties.

[0054] When the patient gets up, the neck support structure 2 automatically resets under the pushing of the first compression spring; the head fixing structure 6 automatically resets under the pushing of the third compression spring; the head support structure 3 automatically resets under the pushing of the second compression spring; during the reset process of the head support structure 3, under the action of the transmission mechanism 4, the two sliding seats 5 slide synchronously along the first sliding grooves 101 in the direction of moving away from each other to realize the reset.

[0055] In a further embodiment, the transmission mechanism 4 can be arranged to include a first hydraulic cylinder body 41, a first piston rod 42, two second hydraulic cylinder bodies 43 and two second piston rods 44. The first hydraulic cylinder body 41 is respectively communicated with the two second hydraulic cylinder bodies 43. The first hydraulic cylinder body 41 is filled with hydraulic fluid during use. The first piston rod 42 is arranged on the head support structure 3 and is slidably inserted into the first hydraulic cylinder body 41. The second piston rod 44 is arranged on the sliding seat 5 and is slidably inserted into the second hydraulic cylinder body 43.

[0056] Specifically in this embodiment, as Figure 7 shown, the first hydraulic cylinder body 41 is arranged as a cylindrical structure and is vertically installed on the top of the machine base 1. The first hydraulic cylinder body 41 is located between the two groups of second mounting rings 12 and is located inside the second mounting rings 12. The second hydraulic cylinder body 43 is arranged as a cylindrical structure, and its axis is parallel to the length direction of the machine base 1 during installation and is arranged on the top of the machine base 1. The two second hydraulic cylinder bodies 43 are respectively located on both sides of the first hydraulic cylinder body 41. As Figure 3 shown, the first piston rod 42 is arranged as an inverted T-shaped columnar structure and has a first small round rod section and a first large round rod section. The end of the first small round rod section is vertically arranged at the bottom of the head support structure 3, and the first large round rod section is slidably inserted into the first hydraulic cylinder body 41. The second piston rod 44 is arranged as a T-shaped columnar structure and has a second small round rod section and a second large round rod section. The end of the second small round rod section is vertically arranged on the inner side plate surface of the sliding seat 5, and the second large round rod section is slidably inserted into the second hydraulic cylinder body 43 and divides the inside of the second hydraulic cylinder body 43 into an outer chamber and an inner chamber in the horizontal direction. The second piston rod 44 is arranged close to the bottom of the sliding seat 5.

[0057] To facilitate the connection between the first hydraulic cylinder body 41 and the second hydraulic cylinder body 43, as Figure 3 shown, a connecting pipe 45 is communicated between the first hydraulic cylinder body 41 and the two second hydraulic cylinder bodies 43, and the connecting pipe 45 is communicated with the outer chamber of the second hydraulic cylinder body 43.

[0058] More specifically, to facilitate better providing the driving force for the first piston rod 42 to reset, a fourth compression spring is sleeved on the first small round rod section of the first piston rod 42, and the fourth compression spring is connected between the head support structure 3 and the first hydraulic cylinder body 41 at the same time.

[0059] It can be understood that the hydraulic fluid can be set as hydraulic oil.

[0060] During use, when the head support structure 3 moves downward, on the one hand, the second compression spring and the fourth compression spring are synchronously compressed, and on the other hand, the first piston rod 42 is driven to gradually insert into the first hydraulic cylinder body 41. Under the pushing of the first piston rod 42, the hydraulic oil enters the outer chamber of the second hydraulic cylinder body 43 through the connecting pipe 45. Under the hydraulic pushing of the hydraulic oil, the two sliding seats 5 move synchronously along the first chute 101 in the direction of approaching each other; when the head fixing structure 6 contacts the patient's head, as the sliding seat 5 continues to move, the two head fixing structures 6 move synchronously in the direction of moving away from each other under the pushing of the patient's head, and while compressing the third compression spring, the patient's head is clamped.

[0061] When the patient gets up, under the combined pushing of the second compression spring and the fourth compression spring, the head support structure 3 moves upward, and the head support structure 3 drives the first piston rod 42 to gradually pull out of the first hydraulic cylinder body 41; during the process of the first piston rod 42 pulling out of the first hydraulic cylinder body 41, the volume of the cavity containing the hydraulic oil in the first hydraulic cylinder body 41 gradually increases and the pressure gradually decreases. Since the cavity containing the hydraulic oil in the first hydraulic cylinder body 41 is connected to the outer chamber of the second hydraulic cylinder body 43 through the connecting pipe 45, the pressure in the outer chamber of the second hydraulic cylinder body 43 gradually decreases, and the pressure in the inner chamber of the second hydraulic cylinder body 43 remains unchanged. As a result, a pressure difference appears between the inner and outer chambers of the second hydraulic cylinder body 43. Under the push of the pressure difference, the second piston rod 44 gradually pulls out of the second hydraulic cylinder body 43 and synchronously drives the two sliding seats 5 to move synchronously along the first chute 101 in the direction of moving away from each other to achieve reset.

[0062] In a further embodiment, since the body shapes of different patients are different, the body shape of the patient at least includes the head and neck size, the head and neck weight, and the head and neck shape. If the same clamping method is adopted, when facing a patient with a smaller body shape, it is easy to have too small a clamping force, resulting in no protection; while when facing a patient with a larger body shape, it is easy to have too large a clamping force, resulting in excessive clamping. To solve this problem, an adjustment mechanism is provided on the machine base 1, and the adjustment mechanism is configured to fix the position of the head fixing structure 6 when the clamping force of the two head fixing structures 6 on the patient's head is equal to a preset value.

[0063] During use, when the clamping force of the two head fixing structures 6 on the patient's head is equal to the preset value, the position of the head fixing structure 6 can be fixed through the adjustment mechanism, so as to ensure that patients of any body shape receive the same clamping force on their heads. On the one hand, it avoids the damage caused by too large a clamping force, and on the other hand, it avoids the inability to provide protection due to too small a clamping force, which is beneficial to improving the versatility.

[0064] In a further embodiment, the adjusting mechanism is arranged to include a first rotating shaft 71, a second rotating shaft 72, an open rotating ring 73, an open fixing ring 74, a rack 75, a gear, a first bevel gear 76, a second bevel gear 77 and a transmission assembly, each having two in number. The rack 75 is arranged on the head fixing structure 6 and extends along the sliding direction of the head fixing structure 6. The first rotating shaft 71 is inserted into the sliding seat 5 and can rotate. The gear is sleeved on the first rotating shaft 71 and meshes with the rack 75. The first bevel gear 76 is sleeved on the first rotating shaft 71. The second rotating shaft 72 is inserted into the second piston rod 44 and can rotate. The second bevel gear 77 is sleeved on the second rotating shaft 72 and meshes with the first bevel gear 76. The open fixing ring 74 is inserted into the second hydraulic cylinder block 43. The open rotating ring 73 is sleeved on the second piston rod 44, inserted into the second hydraulic cylinder block 43 and can rotate. The open rotating ring 73 has corresponding first and second positions before and after rotation. When in the first position, the opening of the open rotating ring 73 corresponds to and communicates with the opening of the open fixing ring 74. When in the second position, the opening of the open rotating ring 73 and the opening of the open fixing ring 74 are completely misaligned. The transmission assembly is configured to be able to transmit the movement of the second rotating shaft 72 to the open rotating ring 73.

[0065] Specifically in this embodiment, as Figure 6 shown, the inner end of the rack 75 is vertically installed on the outer strip surface of the head fixing structure 6, and the outer end is suspended. The rack 75 is located between two third mounting columns at the same time. To avoid interference, as Figure 8 shown, a second chute 501 is vertically and penetratingly opened on the plate surface of the sliding seat 5. The second chute 501 is located between two third mounting rings 51. When installed, the rack 75 is slidably inserted into the second chute 501. As Figure 9 shown, to facilitate the installation of the first rotating shaft 71 and the second rotating shaft 72, an L-shaped first installation groove 502 is opened inside the sliding seat 5. The first installation groove 502 is provided with a vertically connected first column groove section and a second column groove section. The first column groove section is vertically arranged inside the sliding seat 5, and the axis of the second column groove section is coincidentally arranged inside the second piston rod 44. As Figure 5 shown, when installed, the first rotating shaft 71 is inserted into the first column groove section with its axis coinciding and can rotate self. When installed, the second rotating shaft 72 is inserted into the second column groove section with its axis coinciding and can rotate self. The first bevel gear 76 is arranged near the bottom of the first rotating shaft 71. The second bevel gear 77 is arranged near the outer end of the second rotating shaft 72.

[0066] As Figure 10 shown, the open rotating ring 73 is arranged in a C-shaped structure. As Figure 4As shown, when installed, the open rotating ring 73 is inserted into the outer chamber of the second hydraulic cylinder block 43, and at the same time, it is sleeved on the second piston rod 44 and can rotate self - sufficiently. When the open rotating ring 73 is in the first position, the opening of the open rotating ring 73 is arranged downward. The open fixed ring 74 is arranged in a C - shaped structure, and when installed, it is fixedly inserted into the outer chamber of the second hydraulic cylinder block 43 and is arranged closely adjacent to the open rotating ring 73. The opening of the open fixed ring 74 is arranged downward.

[0067] Initially, the open rotating ring 73 is in the first position, and the opening of the open rotating ring 73 corresponds to and communicates with the opening of the open fixed ring 74.

[0068] During use, when the head fixing structure 6 contacts the patient's head, as the sliding seat 5 continues to move, the two head fixing structures 6 move synchronously in the direction away from each other under the pushing of the patient's head, and while compressing the third compression spring, the patient's head is clamped. During the movement of the head fixing structure 6, the head fixing structure 6 synchronously drives the rack 75 to insert into the first installation groove 502. The rack 75 drives the first rotating shaft 71 to rotate self - sufficiently through the meshing with the gear. The first rotating shaft 71 drives the second rotating shaft 72 to rotate self - sufficiently through the meshing between the first bevel gear 76 and the second bevel gear 77. The second rotating shaft 72 drives the open rotating ring 73 to rotate self - sufficiently through the transmission component, so that the open rotating ring 73 moves from the first position to the second position, and at the same time, the opening of the open rotating ring 73 and the opening of the open fixed ring 74 are gradually misaligned.

[0069] When the opening of the open rotating ring 73 and the opening of the open fixed ring 74 are completely misaligned, at this time, the clamping force of the two head fixing structures 6 on the patient's head is equal to the preset value, and the position of the head fixing structure 6 is fixed.

[0070] When the patient gets up, under the pushing of the third compression spring, the head fixing structure 6 moves in the direction away from the sliding seat 5. During the movement of the head fixing structure 6, the head fixing structure 6 synchronously drives the rack 75 to pull out from the first installation groove 502. The rack 75 drives the first rotating shaft 71 to rotate self - sufficiently through the meshing with the gear. The first rotating shaft 71 drives the second rotating shaft 72 to rotate self - sufficiently through the meshing between the first bevel gear 76 and the second bevel gear 77. The second rotating shaft 72 drives the open rotating ring 73 to rotate self - sufficiently through the transmission component, so that the open rotating ring 73 moves from the second position to the first position, and at the same time, the opening of the open rotating ring 73 and the opening of the open fixed ring 74 are gradually corresponding.

[0071] In a further embodiment, the transmission component can be set to include a first magnetic block and a second magnetic block. The first magnetic block is inserted into the second rotating shaft 72; the second magnetic block is inserted into the open rotating ring 73 and is magnetically connected to the first magnetic block.

[0072] Specifically in this embodiment, for the convenience of installing the first magnetic block, a plurality of second installation grooves are provided on the circumferential side wall of the second rotating shaft 72, and the plurality of second installation grooves are arranged circumferentially. When installing, the second magnetic block is inserted into the second installation grooves; for the convenience of installing the second magnetic block, as Figure 10 shown, a plurality of installation holes 7301 are provided on the end surface of the opening rotating ring 73, and the plurality of installation holes 7301 are arranged circumferentially. When installing, the second magnetic block is inserted into the installation holes 7301.

[0073] Exemplarily, the number of the installation holes 7301 can be set to nine, and the nine installation holes 7301 are evenly arranged circumferentially.

[0074] It can be understood that both the first magnetic block and the second magnetic block can be set as magnets, and the opposite sides with opposite magnetic poles are arranged opposite to each other; it is also possible that the first magnetic block is set as a magnet and the second magnetic block is made of a magnetic material such as iron, cobalt, nickel, etc.; it is also possible that the second magnetic block is set as a magnet and the first magnetic block is made of a magnetic material such as iron, cobalt, nickel, etc.

[0075] During the use process, when the second rotating shaft 72 rotates, the second rotating shaft 72 synchronously drives the opening rotating ring 73 to rotate self by the magnetic connection between the first magnetic block and the second magnetic block, thereby driving the opening rotating ring 73 to switch between the first position and the second position.

[0076] In other embodiments, when the openings of the opening rotating ring 73 and the opening fixed ring 74 are completely misaligned, since the communication pipe 45 and the second hydraulic cylinder body 43 are disconnected, the head support structure 3 together with the first piston rod 42 cannot continue to move downward. Since the body types of different patients are different, the body type of the patient at least includes the head and neck size, the head and neck weight, and the head and neck shape. For patients with a larger body type, the downward movement amount required for the head support structure 3 is more. To avoid affecting the patient experience, it is set that an adaptation mechanism 8 is further provided on the machine base 1, and the adaptation mechanism 8 is configured to enable the first piston rod 42 to slide in the first hydraulic cylinder body 41 after the position of the head fixing structure 6 is fixed.

[0077] In a further embodiment, the adaptation mechanism 8 is set to include a sliding plate 81 and a third hydraulic cylinder body 82, and the third hydraulic cylinder body 82 is communicated with the first hydraulic cylinder body 41; the sliding plate 81 is elastically and slidably inserted into the third hydraulic cylinder body 82.

[0078] Specifically in this embodiment, as Figure 3As shown, the third hydraulic cylinder body 82 is arranged in a cylindrical structure and is vertically installed at the bottom of the machine base 1; the sliding plate 81 is arranged in a disc-shaped structure and is coaxially inserted inside the third hydraulic cylinder body 82; to facilitate the elastic sliding of the sliding plate 81, a fifth compression spring is inserted inside the third hydraulic cylinder body 82, and the fifth compression spring is connected between the sliding plate 81 and the third hydraulic cylinder body 82. Under the push of the fifth compression spring, the sliding plate 81 has a tendency to slide upward.

[0079] During use, when the openings of the opening rotating ring 73 and the opening fixed ring 74 are completely misaligned, as the head support structure 3 continues to move downward, the first piston rod 42 moves downward synchronously. Under the hydraulic push of the hydraulic oil, the sliding plate 81 moves downward synchronously and simultaneously compresses the fifth compression spring.

[0080] When the patient gets up, under the push of the fifth compression spring, the sliding plate 81 moves upward and simultaneously pushes the hydraulic oil into the first hydraulic cylinder body 41.

[0081] In some other embodiments, to further ensure the support stability of the neck support structure 2, a clamping mechanism is provided on the machine base 1. The clamping mechanism is configured to fix the position of the neck support structure 2 when the clamping force of the two head fixing structures 6 on the patient's head is equal to a preset value.

[0082] In a further embodiment, the clamping mechanism is provided to include a first comb tooth portion 91, two wedge portions 92, and two sliders 93. The first comb tooth portion 91 is provided on the neck support structure 2; the wedge portions 92 are provided on the head fixing structure 6; the sliders 93 are provided on the sliding seat 5 and can elastically slide along a direction perpendicular to the sliding direction of the head fixing structure 6. The sliders 93 can both form a guiding fit with the wedge portions 92 and form a clamping fit with the first comb tooth portion 91.

[0083] Specifically in this embodiment, as Figure 1 and Figure 3 shown, the first comb tooth portion 91 is provided to be composed of a plurality of strip-shaped grooves. The strip-shaped grooves extend along the length direction of the machine base 1 and are opened on the side wall surface of the neck support structure 2 facing the head support structure 3. The plurality of strip-shaped grooves are arranged at equal intervals in the vertical direction.

[0084] Exemplarily, the number of strip-shaped grooves can be set to nine, and the nine strip-shaped grooves are arranged at equal intervals in the vertical direction.

[0085] As Figure 6 shown, the wedge portion 92 is provided on the outer strip surface of the head fixing structure 6 and forms an L-shaped structure together with the head fixing structure 6; the slider 93 is provided in an inverted T-shaped structure and has a columnar portion and a plate-like portion; to facilitate the installation of the slider 93, as Figure 9 shown, an installation platform 53 is vertically provided on the side wall surface of the sliding seat 5, asFigure 2 As shown, the mounting table 53 is disposed close to the neck support structure 2. A third sliding groove 5301 is formed in the mounting table 53. The third sliding groove 5301 extends along the width direction of the sliding seat 5 and penetrates through the side wall surface of the mounting table 53 to facilitate the exposure of the plate-shaped portion. The cross-sectional shape of the third sliding groove 5301 is arranged as an inverted T shape. The slider 93 is slidably inserted into the third sliding groove 5301, and the columnar portion is located outside the mounting table 53 and forms a guiding fit with the wedge portion 92. The plate-shaped portion can form a clamping fit with the first comb tooth portion 91.

[0086] To facilitate the elastic sliding of the slider 93, a tension spring is inserted inside the third sliding groove 5301. The tension spring is connected between the mounting table 53 and the slider 93. Under the action of the tension spring, the slider 93 has a tendency to move along the third sliding groove 5301 in the direction close to the sliding seat 5.

[0087] During the process that the two head fixing structures 6 move synchronously in the mutually away direction, the head fixing structures 6 synchronously drive the wedge portion 92 to move in the direction close to the sliding seat 5. The wedge portion 92 synchronously pushes the columnar portion of the slider 93 to move outwards, so that the plate-shaped portion of the slider 93 synchronously moves in the direction close to the neck support structure 2. As the head fixing structures 6 move, when the clamping force of the two head fixing structures 6 on the patient's head is equal to a preset value, the plate-shaped portion of the slider 93 is simultaneously inserted into the strip-shaped groove to support the neck support structure 2.

[0088] In some other embodiments, a bed body structure 10 is further provided on the machine base 1. The bed body structure 10 and the head support structure 3 are respectively located on both sides of the neck support structure 2 to achieve integrated application.

[0089] In some other embodiments, to improve the stability of the head support structure 3 and the sliding seat 5 during movement, as Figure 6 shown, second comb tooth portions 31 are provided on both sides of the head support structure 3. The second comb tooth portions 31 are arranged as groove-shaped structures; as Figure 9 shown, third comb tooth portions 52 are provided on the inner side plate surface of the sliding seat 5. The third comb tooth portions 52 are arranged as convex structures and can be slidably inserted into the second comb tooth portions 31 during use.

[0090] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
