Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a traction bed for fracture patients. Background Art

[0002] The traction nursing bed based on the medical and health big data sharing platform is an innovative medical device that integrates modern information technology with the functions of traditional medical traction equipment. After surgery, patients with pelvic fractures need to lie still on a nursing traction bed for rest and cooperate with traction for rehabilitation. During the recuperation and care period, in order to effectively prevent muscle atrophy and avoid the formation of pressure sores, patients need to turn over regularly.

[0003] Patients with pelvic fractures are generally placed alternately in supine and prone positions. During the turning process, a problem that cannot be ignored arises. The existing turning process is generally performed by the staff. However, after a pelvic fracture, the stability of the fracture ends is destroyed. During the turning process, the rotation of the body may cause the fracture site to be subjected to uneven external forces, such as shear force, torsion force, etc., thereby causing displacement of the fracture ends. This will not only affect the healing of the fracture, but may also aggravate the damage to the surrounding tissues, such as blood vessels and nerves, increasing the patient's pain and the difficulty of treatment. For this reason, we propose a traction bed for fracture patients. Summary of the invention

[0017] The present invention has at least the following beneficial effects:

[0018] 1. Improve the safety of turning over: When the patient turns over, the support component and the follower component can make the pressure airbag fit closely to the patient's pelvic fracture site, move synchronously with the rotation of the body, and continuously and stably support the fracture site. During the whole process of the patient turning over, it provides stable, uniform and appropriate support for the pelvic fracture site, avoiding the risk of uneven force or displacement of the fracture site caused by turning over, minimizing the pain and discomfort of the patient during the turning process, and creating extremely favorable conditions for the smooth healing of pelvic fractures.

[0019] 2. Improve patient comfort: It can provide appropriate support for the patient's pelvic fracture during the turning process. Compared with manual assistance, the follow-up support is more stable and precise, and will not cause secondary injury to the patient due to small errors in the operation of medical staff. Moreover, because it can effectively avoid the aggravation of pain at the fracture site, the patient will be more relaxed when turning over, reducing the fear of turning over.

[0020] 3. Optimize rehabilitation effect: During the turning process, continuous stable support helps maintain a good environment at the fracture site, ensures the normal healing of the fracture, and ensures the blood supply to the fracture site and the normal function of the surrounding tissues. Good blood circulation can provide sufficient nutrients and oxygen for fracture healing, promote the formation of callus and the repair of fractures. At the same time, reducing the damage to the surrounding tissues is also conducive to patients to carry out rehabilitation training earlier and accelerate the rehabilitation process.

[0021] 4. Improve the training and rehabilitation effect: The traction massage component is connected with the support component. When the patient repeatedly pulls and releases the pull ring, the volume of the airbag will change alternately. The alternating airbag can produce a rhythmic massage effect on the patient's buttocks, so that while the patient exercises his arms independently, the buttocks can also receive continuous and effective massage stimulation. This has a very significant positive effect on promoting blood circulation in the pelvic fracture site, relieving muscle tension, accelerating fracture healing, and improving the overall functional recovery of the pelvis, thereby comprehensively improving the recovery effect of pelvic fractures.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figure 1-Figure 11 As shown, the present invention provides a technical solution: a traction bed for fracture patients, comprising a bed body 1, which is a traction bed nursing bed body based on a medical health big data sharing platform. The traction bed nursing bed body is built-in with an advanced communication module, such as a WiFi or Bluetooth module (not shown), which can upload various data collected by sensors to the big data sharing platform in real time. During the process of the patient using the traction bed, the system will continue to collect the patient's real-time data, such as heart rate, blood pressure (obtained through an external wearable monitoring device), the patient's subjective feedback on the traction force, etc., and upload these data again to the big data sharing platform. According to the updated analysis on the sharing platform, if the patient is found to have abnormal conditions during the traction process, such as too fast heart rate, abnormally high blood pressure, etc., the system will automatically sound an alarm, and suspend or adjust the traction operation according to the preset emergency plan, and notify medical staff to come and deal with it. A frame 2 is provided on the bed 1, and a lifting ring or pulley group is provided on the frame 2. A traction rope is passed through the lifting ring (pulley group), one end of the traction rope is used to connect to the counterweight flange, and the other end of the traction rope can be connected to a fixed structure, which can be a splint, a traction belt, etc., so as to achieve traction for fracture patients. The above is the existing technology and will not be repeated here.

[0040] In addition, the fracture patient traction bed also includes a follower component 3 and a support component 4, the support component 4 includes an airbag mechanism 41 and an adjustment mechanism 42, the airbag mechanism 41 is used to support the patient's fractured part, preferably for pelvic fractures, and a plurality of pressure sensors 6 are installed on the pressure surface of the airbag mechanism 41, the pressure sensor 6 is used to monitor the pressure of the airbag mechanism 41 pressing the patient's pelvic part, the adjustment mechanism 42 is used to realize the inflation and deflation of the airbag mechanism 41, and the adjustment mechanism 42 can adaptively adjust the local inflation and deflation of the airbag mechanism 41 according to the monitoring situation of the pressure sensor 6, so as to realize the adaptive adjustment of the low pressure, the follower component 3 is arranged on one side of the bed body 1, the support component 4 is installed on the follower component 3, and the follower component 3 includes a moving mechanism The moving mechanism 31 and the deflection mechanism 32, the moving mechanism 31 is used to realize the lateral and longitudinal movement of the airbag mechanism 41, so as to realize the movement of the position of the airbag mechanism 41 in a larger range, and the deflection mechanism 32 is used to realize the adjustment of the inclination of the airbag mechanism 41, so that when the patient with pelvic fracture turns over, the inclination of the airbag mechanism 41 can be adaptively adjusted according to the change of the patient's turning over angle, so as to provide stable, uniform and just the right support force for the pelvic fracture site in the whole process of the patient turning over, which not only effectively avoids the risk of uneven force or displacement of the fracture site caused by turning over, and minimizes the pain and discomfort of the patient in the process of turning over, but also creates extremely favorable conditions for the smooth healing of pelvic fractures, and significantly improves the nursing quality and rehabilitation effect of patients.

[0041] Among them, see Fig. 9 As shown, the airbag mechanism 41 includes a containing frame 411 and a pressure airbag 412 arranged in the containing frame 411. The pressure airbag 412 includes a central airbag 4122 and multiple peripheral airbags 4121. The peripheral airbags 4121 protrude outward from the central airbag 4122, so that when contacting the patient's pelvic part, they can better wrap and support the patient's buttocks. A pressure sensor 6 is installed on the outer wall of the peripheral airbag 4121.

[0042] See also Figure 7 and Figure 8As shown, the adjustment mechanism 42 includes an air pump 421, the air outlet end of the air pump 421 is connected to a first air pipe 422, the peripheral air bags 4121 of the peripheral air bags 4121 are all connected to second air pipes 423, the ends of the second air pipes 423 are commonly connected to the first air pipe 422, the second air pipe 423 is also connected to an exhaust pipe (not shown), and the second air pipe 423 and the exhaust pipe are both installed with solenoid valves 424. When a patient with a pelvic fracture turns over, the follower assembly 3 can be used to first make the air bag mechanism 41 close to the patient's pelvic part. As the patient turns over, the pressures of the pressure sensors 6 on the central air bag 4122 and the multiple peripheral air bags 4121 are different, and the pressure sensors 6 transmit their respective pressures to the traction bed. A controller (not shown) is provided, which can accurately control the opening of the solenoid valve 424 on the corresponding second air pipe 423. When it is detected that the pressure of some airbags is too low, the controller will adjust the solenoid valve 424 to an appropriate opening to allow the gas to flow smoothly into these airbags, thereby realizing the inflation operation; and once it is detected that the pressure of some airbags is too high, the controller will control the solenoid valve 424 to change the opening so that the gas in the airbag can be discharged to achieve the purpose of deflation. In this way, the pressure of each airbag can be effectively dynamically balanced and accurately adjusted to ensure continuous support for the patient during the turning process, and prevent the fracture site of the patient from being subjected to uneven external force and causing displacement of the fracture ends.

[0043] When the outer airbag 4121 and the central airbag 4122 are inflated, air delivery is achieved by timely starting the air pump 421.

[0044] Furthermore, the overall shape of the outer airbag 4121 and the central airbag 4122 can be designed according to ergonomics to achieve better support.

When the first motor 311 is started, the output end of the first motor 311 can be used to drive the first screw rod 312 to rotate, thereby realizing the movement of the first vertical plate 313 installed on the screw rod nut seat along the length direction of the bed body 1.

[0046] The moving mechanism 31 also includes a second vertical plate 315 vertically fixed to the upper end surface of the L-shaped connecting plate 314, a through groove is provided in the middle of the second vertical plate 315, a second motor 318 is installed near the middle of the lower end surface of the L-shaped connecting plate 314, a second screw rod 316 in the through groove is installed at the top of the second motor 318, a second connecting strip 327 is installed on the outside of the second screw rod 316 through a screw nut seat, two first telescopic rods 317 are installed between the bottom side surface of the L-shaped connecting plate 314 and the first vertical plate 313, and the first telescopic rod 317 is preferably an electric telescopic rod or a pneumatic telescopic rod. The two first telescopic rods 317 are located on both sides of the second motor 318, and the lower end surface of the L-shaped connecting plate 314 is also connected to a guide bar 319. The top of the first vertical plate 313 is provided with a guide groove that matches the guide bar 319. By starting the second motor 318, the output end of the second motor 318 can be used to drive the second screw rod 316 to rotate, thereby realizing the rise or fall of the second connecting bar 327 installed on the screw rod nut seat. According to the actual turning over needs, the height position of the airbag mechanism 41 can be flexibly and accurately adjusted to provide more comfortable and appropriate turning over assistance for patients with pelvic fractures.

[0047] The first telescopic rod 317 can be used to realize the extension and retraction of the airbag mechanism 41 along the width direction of the bed body 1, thereby effectively adapting to the actual needs of adaptive support in various situations and providing patients with a support experience that better fits the body curve, is stable and comfortable.

[0048] See also Figure 7 As shown, the deflection mechanism 32 includes a third motor 321 and a first connecting bar 325. The third motor 321 is installed on one side of the second connecting bar 327 through a mounting bar. A first gear 322 is installed at the output end of the third motor 321.

The second telescopic rod 326 is preferably an electric telescopic rod or a pneumatic telescopic rod. The third motor 321 is started. 321, the output end of the third motor 321 can be used to drive the first gear 322 to rotate, and the first gear 322 drives the meshing second gear 323 to rotate, so as to realize the rotation of the connecting rod 324, and then realize the radial deflection of the airbag mechanism 41 at a larger angle, so as to adapt to the turning needs of fracture patients, provide patients with more comfortable, safe and special follow-up support conditions that meet the special requirements of their physical conditions, and greatly improve the practicality and effectiveness of the traction bed in the care of fracture patients. Secondly, by starting the first telescopic rod 317, the deflection angle of the airbag mechanism 41 can be finely and effectively adjusted within a small range, which can further improve the flexibility and accuracy of the auxiliary support turning function.

[0049] In summary, in actual use, the following is a specific explanation based on patients with pelvic fractures:

[0050] Patients with pelvic fractures generally adopt an alternating method of recuperation between prone and supine positions. When they need to turn over from supine to prone position, they first start the follow-up component 3, and use the follow-up component 3 to make the airbag mechanism 41 close to the patient's buttocks. In this process, it can accurately locate and gradually approach the target position. As the patient begins to turn over, the follow-up component 3 continues to exert its dynamic adjustment function to make the airbag mechanism 41 fit tightly to the patient's buttocks. This fitting process is not static, but is adaptively adjusted in real time as the turning angle continues to increase. Because the patient's body posture and force conditions are constantly changing when turning over, the pressure sensors 6 originally located on the peripheral airbags 4121 and the central airbags 4122 will be sensitive. The change can be captured accurately. After the pressure sensor 6 feeds back the pressure change, the controller can be used in time to control the opening of the corresponding solenoid valve 424 to realize the inflation or deflation operation of the corresponding airbag. This inflation or deflation process is not carried out blindly, but is closely coordinated with the movement trajectory and speed of the follower component 3. Its purpose is to ensure that each airbag always maintains approximately the same pressure on the patient's buttocks no matter how the patient's posture changes during the turning process. In this way, the patient's body can be continuously and stably supported during the entire turning process, effectively avoiding the physical discomfort and injury risks that may be caused by the turning operation, greatly improving the patient's safety and comfort during the turning process, and providing a strong guarantee for the patient's rehabilitation treatment.

[0051] Among them, the inflation and deflation of the airbag can be specifically explained as follows: for example, if the patient turns sideways to 30 degrees, the follower component 3 follows up to adjust the movement of the airbag mechanism 41 to match the patient's turning sideways to 30 degrees, and during the adjustment process, the adjustment mechanism 42 adjusts the airbag in the lower part of the airbag mechanism 41 to deflate appropriately, and at the same time, the airbag in the upper part is inflated appropriately to ensure stable support of the buttocks.

[0052] In addition, the cooperation of the above-mentioned follower component 3 and the support component 4 can also be used to support the turning over of patients with fractures in other parts of the body, which is beneficial to the legs. The airbag mechanism 41 can also be used to self-adjust and support the patient's fractured legs to achieve protection during the turning over process.

[0053] Example 2: Please refer to Figure 1-Figure 4 As shown, this embodiment is extended on the basis of the embodiment 1: the traction bed for fracture patients also includes a traction massage component 5, which is arranged on the frame 2, and the end of the traction massage component 5 is connected to the adjustment mechanism 42. The traction massage component 5 is used to synchronously realize the inflation and deflation of the airbag mechanism 41 during the traction exercise of the fracture patient to massage the fracture.

[0054] Among them, see Fig.10 and Fig.11 As shown, the traction massage assembly 5 includes a pull rope 52, a piston 51 and a third air pipe 53 which are connected in sequence. The end of the third air pipe 53 away from the piston 51 is connected to the second air pipe 423. The end of the pull rope 52 away from the piston 51 is equipped with a pull ring. The pull rope 52 passes through the pulley set on the traction bed. The piston 51 is installed on the frame 2 through the installation structure to ensure the stability of the piston 51 when the pull rope 52 is pulled up.

[0055] The first air pipe 422 , the second air pipe 423 , and the third air pipe 53 are all flexible pipes.

[0056] See also Fig.10 and Fig.11 As shown, the piston member 51 includes a threaded cylinder 511 and a connecting cylinder 512, the bottom end of the cylinder 511 is through, one end of the third air pipe 53 facing away from the third air pipe 53 is connected to the connecting cylinder 512, a piston 513 is provided at the lower end of the cylinder 511, one end of the pull rope 52 facing away from the pull ring is connected to the upper end surface of the piston 513, and a spring 514 is connected between the upper end surface of the piston 513 and the top of the cylinder 511.

[0057] Through the above, in actual clinical application scenarios, when rehabilitation treatment is required for patients with pelvic fractures, the following operation method can be adopted: first, adjust the patient to a prone position to ensure that the patient is in a comfortable and stable state, then start the follower component 3, and under its precise power transmission and control, the pressure airbag 412 of the airbag mechanism 41 is prompted to slowly fit the patient's buttocks and apply a moderate pressure. Then, instruct the patient to hold the pull ring with his hand. At this time, the patient's hand applies force to pull the pull rope 52. During the force process, the pull rope 52 will effectively transfer this pulling force to the piston 513 inside the cylinder 511, thereby driving the piston 513 to move upward smoothly along the inner wall of the cylinder 511. During the upward movement of the piston 513, the air inside each airbag will be gradually drawn into the cylinder 511 under the action of the pressure difference, so that the volume of the airbag is gradually reduced. It is worth noting that during this process, the spring 514 will be squeezed due to the upward movement of the piston 513, so that it is in a compressed state, and the elastic potential energy of the spring 514 will gradually accumulate accordingly;

[0058] When the patient completes a pull ring pulling action and releases the pull ring, the elastic potential energy stored in the spring 514 will be released, and the spring 514 will quickly recover to its original shape and state. During the recovery process, the spring 514 will exert a downward thrust on the piston 513, pushing the piston 513 to move downward along the inner wall of the cylinder 511. As the piston 513 moves downward, the air in the cylinder 511 will flow back into each airbag under the drive of pressure, causing the volume of the airbag to increase again.

[0059] As the patient repeatedly pulls and releases the pull ring, the volume of the airbag will change alternately between large and small. The airbag that changes in size alternately can produce a rhythmic massage effect on the patient's buttocks, simulating the techniques and strength changes similar to artificial massage. While the patient is exercising his arms independently, the buttocks can also receive continuous and effective massage stimulation, which has a very significant positive effect on promoting blood circulation in the pelvic fracture site, relieving muscle tension, accelerating fracture healing, and improving the overall functional recovery of the pelvis, thereby comprehensively improving the recovery effect of pelvic fractures.
