Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a prone support frame for critically ill patients. Background Technology

[0002] Critically ill patients typically refer to those with severe conditions and unstable vital signs, posing a high risk of death. These patients may suffer severe impairment of bodily functions due to severe trauma, septic shock, acute respiratory distress syndrome, or multiple organ failure. Prone ventilation, as an important respiratory support therapy, can effectively improve oxygenation, promote drainage of pulmonary secretions, prevent sputum accumulation, and reduce the risk of ventilator-associated lung injury, and has been widely used in intensive care units.

[0003] In clinical use, existing prone support devices require patients' heads to be in direct contact with the headrest for extended periods. However, the headrest portion of traditional support frames generally employs a fixed structure design, and its tilt angle cannot be flexibly adjusted according to individual patient differences, changes in condition, or comfort needs. This results in poor fit for patients of different body types. Furthermore, the headrest surface, after prolonged contact with the patient's skin, sweat, and respiratory secretions, easily becomes a potential medium for bacterial colonization and cross-infection. Because existing devices lack a quick-replacement mechanism, the headrest disassembly process is cumbersome, failing to meet the requirements of frequent clinical cleaning and disinfection, and posing a risk of nosocomial infection control. Therefore, a prone support frame for critically ill patients is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a prone support frame for critically ill patients, which aims to solve the problem that the headrest part of the existing support frame generally adopts a fixed structure design, and its tilt angle cannot be flexibly adjusted according to individual patient differences, changes in condition or comfort needs, resulting in poor adaptability for patients of different body types.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prone support frame for critically ill patients, including a mounting base, an adjustment mechanism on the back of the mounting base, and a headrest on the top of the adjustment mechanism;

[0006] The adjustment mechanism includes a bracket and a fixed column. The two ends of the fixed column are rotatably connected to the inner wall of the bracket via bearings. A push post is slidably connected to the inner wall of the fixed column. A first spring is provided at the right end of the push post. A positioning plate is fixedly connected to the bottom wall of the push post. A positioning post is fixedly connected to the left wall of the positioning plate. A positioning hole is opened on the outer wall of the bracket. The left end of the positioning post is inserted into the inner wall of the positioning hole.

[0007] As a further description of the above technical solution: the fixing column is fixedly connected to the inner wall of the mounting base, the right end of the pressing column is fixedly connected to a guide column, and the inner wall of the first spring is sleeved with the outer wall of the guide column.

[0008] As a further description of the above technical solution: the left end of the first spring abuts against the left end of the push post, and the right end of the first spring abuts against the inner wall of the fixed post.

[0009] As a further description of the above technical solution: the bottom of the bracket is provided with a disassembly and assembly mechanism, which includes a positioning frame and a fixing seat, and the top of the fixing seat is fixedly connected to the bottom of the bracket.

[0010] As a further description of the above technical solution: a guide rod is slidably connected to the inner wall of the fixed base, one end of the guide rod is fixedly connected to the back of the positioning frame, and the other end of the guide rod is fixedly connected to a limit block.

[0011] As a further description of the above technical solution: a second spring is sleeved on the outer wall of the guide rod, one end of the second spring abuts against the back of the positioning frame, and the other end of the second spring abuts against the front of the fixing seat.

[0012] As a further description of the above technical solution: the front of the positioning frame is fixedly connected to a plug, the upper surface of the bracket is provided with a through hole, and a socket is inserted into the inner wall of the through hole.

[0013] As a further description of the above technical solution: the top of the socket is fixedly connected to the bottom of the headrest, the front of the socket has a socket hole, and the front end of the plug is inserted into the inner wall of the socket hole.

[0014] This utility model has the following beneficial effects:

[0015] 1.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 3 One embodiment of this utility model is a prone support frame for critically ill patients, including a mounting base 1, an adjustment mechanism 2 on the back of the mounting base 1, and a headrest 4 on the top of the adjustment mechanism 2. The tilt angle of the headrest 4 can be adjusted by the adjustment mechanism 2, thereby facilitating patient use.

[0027] The adjustment mechanism 2 includes a bracket 201 and a fixing column 202. The two ends of the fixing column 202 are rotatably connected to the inner wall of the bracket 201 via bearings. A push post 203 is slidably connected to the inner wall of the fixing column 202. A first spring 205 is provided at the right end of the push post 203. A positioning plate 206 is fixedly connected to the bottom wall of the push post 203. A positioning post 207 is fixedly connected to the left wall of the positioning plate 206. A positioning hole 208 is provided on the outer wall of the bracket 201. The left end of the positioning post 207 is inserted into the inner wall of the positioning hole 208. The user can push the positioning plate 206 to the right by pressing the push post 203, so that the positioning post 207 on the positioning plate 206 is disengaged from the positioning hole 208. At this time, the bracket 201 can be rotated and adjusted. After adjustment, the push post 203 is released so that the positioning post 207 is inserted into another positioning hole 208 to fix the bracket 201.

[0028] The fixing post 202 is fixedly connected to the inner wall of the mounting base 1. The right end of the pressing post 203 is fixedly connected to the guide post 204. The guide post 204 prevents the first spring 205 from disengaging from the inside of the fixing post 202. The inner wall of the first spring 205 is fitted with the outer wall of the guide post 204. The left end of the first spring 205 abuts against the left end of the pressing post 203, and the right end of the first spring 205 abuts against the inner wall of the fixing post 202. The first spring 205 facilitates the reset of the pressing post 203.

[0029] Reference Figure 4 - Figure 6 The bottom of the bracket 201 is provided with a disassembly and assembly mechanism 3, which includes a positioning frame 301 and a fixing seat 302. The top of the fixing seat 302 is fixedly connected to the bottom of the bracket 201. A guide rod 303 is slidably connected to the inner wall of the fixing seat 302. One end of the guide rod 303 is fixedly connected to the back of the positioning frame 301. The guide rod 303 can limit and guide the positioning frame 301. The other end of the guide rod 303 is fixedly connected to a limit block 305. The limit block 305 can prevent the guide rod 303 from detaching from the fixing seat 302.

[0030] A second spring 304 is sleeved on the outer wall of the guide rod 303. One end of the second spring 304 abuts against the back of the positioning frame 301, and the other end of the second spring 304 abuts against the front of the fixed seat 302. The second spring 304 facilitates the resetting of the positioning frame 301.

[0031] The positioning frame 301 has a fixedly connected insert block 306 on its front side. The upper surface of the bracket 201 has a through hole 309. A socket 307 is inserted into the inner wall of the through hole 309. The top of the socket 307 is fixedly connected to the bottom of the headrest 4. The front side of the socket 307 has a socket hole 308. The front end of the insert block 306 is inserted into the inner wall of the socket hole 308. When the headrest 4 needs to be disassembled and replaced, medical staff can pull the positioning frame 301 to disengage the insert block 306 from the socket hole 308 on the socket 307. At this time, the socket 307 loses its limit, and the headrest 4 can be removed upward from the bracket 201.

[0032] Working principle: When the tilt angle of the headrest 4 needs to be adjusted, the operator presses the push post 203. The push post 203 slides to the right along the inner wall of the fixed post 202 and compresses the first spring 205. The positioning plate 206, which is fixedly connected to the push post 203, moves to the right in sync, causing the positioning post 207 to disengage from the positioning hole 208 of the bracket 201 and release the limit. At this time, the bracket 201 can be rotated around the axis of the fixed column 202. After the headrest 4 rotates with the bracket 201 to the target angle, the push post 203 is released, the first spring 205 resets and pushes the push post 203 to the left. The positioning plate 206 drives the positioning post 207 to insert into the positioning hole 208 at the corresponding position, and the angle of the bracket 201 is locked again, completing the tilt angle adjustment of the headrest 4. When the headrest 4 needs to be replaced, the operator pulls the positioning frame 301 backward. The positioning frame 301 drives the guide rod 303 to slide backward along the inner wall of the fixed seat 302, compressing the second spring 304 and causing the limit block 305 to move backward. The plug block 306, which is fixedly connected to the positioning frame 301, moves backward in sync and completely exits from the plug hole 308 of the socket 307. At this point, the socket 307 at the bottom of the headrest 4 is no longer constrained by the insert block 306 within the through hole 309 of the bracket 201. The operator can then lift the headrest 4 vertically upwards to disengage the socket 307 from the through hole 309, thus completing the removal of the headrest 4. When installing a new headrest 4, insert the socket 307 into the through hole 309, release the positioning bracket 301, and the second spring 304 will reset, pushing the positioning bracket 301 forward. The front end of the insert block 306 will automatically insert into the socket 308 of the socket 307, achieving quick locking of the headrest 4.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
