[0031] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0032] This application provides a head fixation support device for prone position, which can solve the problem in related technologies that some patients may use ventilators or endotracheal intubation during treatment in a prone position. The ventilation stent for prone patients does not have an area for easy placement of ventilator tubing and endotracheal tubing, which limits the use of the stent.
[0033] See Figure 1 and Figure 2 The image shows a prone head support device provided in an embodiment of this application. It may include: a height-adjustable support frame, one end of which is connected to a support plate 2, the support plate 2 having a through groove 21; a head support 3, mounted on the support plate 2, the head support 3 having a ventilation groove 31 facing the through groove 21, the head support 3 having a tube groove 32 communicating with the ventilation groove 31, and the head support 3 also having a neck placement area, the neck placement area being fixed with a tube rope 33. It should be understood that the head support 3 may be made of slow-rebound memory foam material, which can increase comfort and prevent facial pressure sores.
[0034] This embodiment of the application uses a height-adjustable support frame to adjust the final support height of the support plate 2. Typically, the patient's head placement is related to factors such as the height of the mattress. The height-adjustable support frame allows the prone head support device to be used in various scenarios, providing a more comfortable position for the patient when using the head support 3. The head support 3 is installed on the support plate 2 to provide a place for the patient's head. The slots 21 and ventilation slots 31 should be interconnected. When the patient's face is down and their head is supported on the head support 3, the face can breathe freely through the slots 21 and ventilation slots 31. The dimensions of the slots 21 and ventilation slots 31 are such that, in addition to allowing the patient to breathe through their nose, the eyes and mouth can also be accommodated within the ventilation slots 31 and slots 21, minimizing pressure on the patient's face while providing stable head support. Two slots 32 can be provided, with the two slots 32 extending along the head support... The support member 3 is symmetrically arranged along its central axis. Each tube insertion slot 32 can accommodate different ventilator tubing. Patients requiring ventilator use can have two ventilator tubings passed through the corresponding tube insertion slot 32 before being inserted into their mouths. At this time, the bottom area of the tube insertion slot 32 can also support the ventilator tubing, reducing the possibility of the ventilator tubing falling out. The neck placement area is designed to be suspended, with at least part of the neck suspended to reduce pressure on the patient's neck. By fixing the tube insertion rope 33 in the neck placement area, it is easy for the endotracheal tube to pass through the tube insertion rope 33 and extend to the patient. Patients requiring endotracheal intubation can connect the endotracheal tube to the patient through the tube insertion rope 33. The tube insertion rope 33 also provides a fixed support for the endotracheal tube, effectively preventing the endotracheal tube from falling out. This solves the problem in related technologies where ventilation stents are not convenient for ventilator tubing and endotracheal tubes to pass through, thus limiting the use of the stent.
[0035] In some optional embodiments, one end of the height-adjustable support frame is connected to a first one-way ratchet assembly 11. The support plate 2 is unidirectionally rotatably connected to the height-adjustable support frame via the first one-way ratchet assembly 11. The first one-way ratchet assembly 11 can lock the support plate 2 in the opposite direction at any angle. Specifically, the axis of the first one-way ratchet assembly 11 can be perpendicular to the axis of the height-adjustable support frame. The support plate 2 is configured to rotate around the axis of the first one-way ratchet assembly 11. In this embodiment, the support plate 2 is configured such that when it rotates clockwise around the axis of the first one-way ratchet assembly 11, the support plate 2 is equivalent to the height-adjustable support frame rotating, and the rotation angle range is 360°. When the support plate 2 rotates counterclockwise around the axis of the first one-way ratchet assembly 11, the support plate 2 and the height-adjustable support frame remain relatively stationary under the action of the first one-way ratchet assembly 11. The support plate 2 is unidirectionally connected to the height-adjustable support frame via the first one-way ratchet assembly 11, which allows adjustment of the positional relationship between the support plate 2 and the height-adjustable support frame. This facilitates storage when the prone head fixation support device is not in use, and provides stable support for the patient's head during use.
[0036] In some optional embodiments, the first unidirectional ratchet assembly 11 may include: an inner ratchet 111 fixed to the height-adjustable support frame; a rotation drive rod 112 rotatably connected to the height-adjustable support frame, the support member fixed to the side wall of the rotation drive rod 112, and a pawl 1121 that engages with the inner ratchet 111 at one end of the rotation drive rod 112. It should be understood that the inner ratchet 111 is also an internally geared ratchet, with its teeth machined on the inner side of the annular structure. Fixing the inner ratchet 111 to the height-adjustable support frame enables unidirectional rotation of the support member. Optionally, one pawl 1121 may be provided to reduce production costs while still fulfilling the locking function; alternatively, two symmetrically arranged pawls 1121 may be provided to improve locking reliability. In this embodiment, the support plate 2 is fixed to the side wall of the rotating drive rod 112. When the support plate 2 rotates clockwise, it can rotate around the axis of the rotating drive rod 112. When the support plate 2 is manually turned clockwise, the rotating drive rod 112 also rotates synchronously, causing the pawl 1121 to rotate relative to the inner ratchet 111. When the support plate 2 is turned counterclockwise, the rotating drive rod 112 and the inner ratchet 111 remain relatively stationary due to the cooperation of the pawl 1121 and the inner ratchet 111. That is, the support plate 2 and the height-adjustable support frame are locked together.
[0037] See Figures 4 to 6As shown, in some optional embodiments, the first one-way ratchet assembly 11 further includes a guard wheel 113, which is fixed to the height-adjustable support frame. The inner ratchet 111 is fixed in the cavity of the guard wheel 113, and a through hole is provided on the side of the guard wheel 113 away from the height-adjustable support frame. The rotation drive rod 112 includes a dial 1122, which is installed in the cavity of the guard wheel 113, and the pawl 1121 is installed on the dial 1122. The rotation drive rod 112 also includes a rotating rod 1123, which is fixed to the dial 1122 by a connecting rod 1124 passing through the through hole. The support plate 2 is fixed to the rotating rod 1123. It should be understood that the guard plate 113 can have a cavity to accommodate the inner ratchet 111. The guard plate 113 protects the inner ratchet 111 by covering it, reducing the possibility of damage from the external environment and extending its service life. The dial 1122 can be located inside the ratchet hole and is rotatably connected to the height-adjustable support frame. That is, the dial 1122 can rotate relative to the inner ratchet 111. The rotating rod 1123 is installed outside the guard plate 113, so that when the support plate 2 is manually driven to move, the rotating rod 1123 can rotate simultaneously, and also drives the dial 1122 to rotate via the connecting rod 1124, thus realizing the rotation of the support plate 2 relative to the height-adjustable support frame. By setting the rotating rod 1123, the connection area between the support plate 2 and the first one-way ratchet assembly 11 can be increased, making the connection between the support plate 2 and the first one-way ratchet assembly 11 more stable.
[0038] Preferably, the support plate 2 is further connected to a reinforcing member 22, one end of which is fixed to the support plate 2, and the other end is fixed to the rotating rod 1123. The reinforcing member 22 can provide a certain supporting function and enhance the stability of the support plate 2. Specifically, the reinforcing member 22 can be configured as a triangle, with one side attached to the bottom of the support plate 2 and the other side fixed to the rotating rod 1123, which can provide even greater stability.
[0039] See Figure 7As shown, in some optional embodiments, the height-adjustable support frame includes at least two sets of support rods, which are symmetrically arranged. Each set of support rods may include: a hollow rod 12 with a connecting hole on its side; an adjusting rod 13 that passes through the cavity of the hollow rod 12 and has multiple threaded holes spaced apart along the axial direction of the adjusting rod 13; and a connecting threaded component 14 that passes through the connecting hole and the threaded hole corresponding to the connecting hole. The adjusting rod 13 is a solid rod that passes through the cavity of the hollow rod 12. The adjusting rod 13 extends in the same direction as the hollow rod 12. By adjusting the position of the adjusting rod 13 within the hollow rod 12, the height of the support rod assembly can be adjusted. Specifically, the adjusting rod 13 can be moved to a suitable height so that one of the threaded holes on the adjusting rod 13 aligns with the connecting hole. Then, the connecting threaded component 14 is inserted into both the connecting hole and the threaded hole, and the threaded component 14 is threadedly connected and fixed to the threaded hole. By adjusting the height using the hollow rod 12 and the adjusting rod 13, the prone head support device can be adapted to mattresses of different heights, increasing its usability. In this embodiment, the support rod group is configured as two groups, each group of which is fixed with a guard wheel 113 and an inner ratchet 111. Both the guard wheel 113 and the inner ratchet 111 are fixed to the side of the adjusting rod 13 away from the hollow rod 12. The rotating rod 1123 and the guard wheel 113 are installed within the cavity formed by the two groups of support rods. The length of the support plate 2 along the axial direction perpendicular to the adjusting rod 13 is less than the distance between the two groups of support rods, allowing the support plate 2 to rotate. Preferably, the length of the support plate 2 along the axial direction of the hollow rod 12 is slightly less than the length of the hollow rod 12.
[0040] In some optional embodiments, a positioning plate 4 is also connected to the end of the height-adjustable support frame away from the support plate 2. The positioning plate 4 is unidirectionally rotatably connected to the height-adjustable support frame via a second one-way ratchet assembly 15, which can lock the positioning plate 4 in reverse at any angle. In this embodiment, the positioning plate 4 can be used to fix the prone head fixation support device in a designated position. For example, if the positioning plate 4 is inserted between the mattress and the bed board, friction can be used to prevent the positioning plate 4 from shifting. The second one-way ratchet assembly 15 may have the same structure as the first one-way ratchet assembly 11, but with the opposite rotation locking direction. It is installed on the side of the hollow rod 12 away from the adjusting rod 13. Preferably, the positioning plate 4 is configured to rotate counterclockwise around the axis of the second one-way ratchet assembly 15 and lock in reverse when it is desired to rotate clockwise around the axis of the second one-way ratchet assembly 15.
[0041] See Figure 1 and Figure 3As shown, in some optional embodiments, the head support 3 is detachably connected to the support plate 2. Detachably connecting the head support 3 to the support plate 2 facilitates quick replacement of different types of head supports 3 according to clinical needs, such as air cushion type, gel type, and children's type, and also facilitates adjusting the position of the support plate 2 before installing the head support 3. In this embodiment, the support plate 2 has multiple Velcro hook pieces 23 installed on its surface, and the head support 3 has multiple Velcro loop pieces 34 that cooperate with the Velcro hook pieces 23. This method enables quick installation and removal, and also allows for one-handed operation, saving operation time. In some other embodiments, snap-on methods may also be used.
[0042] Preferably, the tube threading rope 33 is an elastic rope. Using an elastic rope allows the tube threading rope 33 to fix various sizes of endotracheal tubes. After the endotracheal tube passes through the tube threading rope 33, the tube threading rope 33 can also lock the endotracheal tube under its own elasticity, reducing the risk of it falling off.
