DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The figure shows a chest fixator, including a back plate 1 and a front chest plate 2. Two symmetrically arranged rear waist side panels 4 are arranged on the outer side of the back plate 1, and two symmetrically arranged front waist side panels 5 are arranged on the outer side of the front chest plate 2. The back plate 1 is connected to the rear waist side panels 4 through a plurality of adjustable telescopic structures 3. The back plate 1 is connected to the rear waist side panels 4 through a plurality of adjustable telescopic structures 3. The front chest plate 2 is also connected to the front waist side panels 5 through a plurality of adjustable telescopic structures 3. A latch plate 302 is fixedly installed on the back plate 1 and the front chest plate 2. A U-shaped plate 301 is sleeved on the outer side of the latch plate 302. The U-shaped plate 301 is rotatably connected to a lifting plate 305 through a rotating shaft 306. A tooth groove 307 is provided on the inner embedded surface of the U-shaped plate 301.

[0031] It is worth noting that when it is necessary to fit different patient sizes, the lifting plate 305 can be quickly lifted outward, the U-shaped plate 301 and the outer tooth plate 302 of the sleeve are loosened, and the rear waist side plate 4 and the front waist side plate 5 are moved horizontally in turn to fit the upper body width of different patients and increase the range. After the adjustment is completed, the lifting plate 305 is rotated again and moved inward to fit, the U-shaped plate 301 and the outer tooth plate 302 of the sleeve will be close, so that the teeth on the tooth plate 302 are inserted into the inside of the tooth groove 307, thereby completing the fixation. It does not use traditional bolts for fixing, and the operation is simple and convenient. It is suitable for rapid clinical use and suitable for patients with a wider range of body widths, which increases practicality.

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The back patch plate 1 and the front chest patch plate 2 are both provided with a sliding cavity 303 at the position of the tooth plate 302, and the tooth plate 302 is fixedly installed inside the sliding cavity 303. The U-shaped plate 301 slides through the inner side of the front waist side plate 5. After the U-shaped plate 301 passes through, support holes 308 are provided on both sides, and the two ends of the rotating shaft 306 are rotatably inserted into the inside of the support hole 308.

[0033] The U-shaped plate 301 can be flexibly rotated in the sliding cavity 303 through the cooperation of the support hole 308 and the rotating shaft 306. The design of the sliding cavity 303 not only provides a stable installation position for the latch plate 302, but also ensures the stability and smoothness of the U-shaped plate 301 during movement. When the lifting plate 305 is opened, the U-shaped plate 301 and the latch plate 302 are loose, and the rear waist side plate 4 and the front waist side plate 5 can be easily moved laterally to adapt to the upper body width of different patients. After the adjustment is completed, By rotating the lifting plate 305, the U-shaped plate 301 and the tooth plate 302 fit tightly together again, and the teeth on the tooth plate 302 are smoothly inserted into the tooth groove 307 of the U-shaped plate 301 to complete the fixation. This design not only simplifies the operation steps and improves the efficiency of use, but also expands the scope of application, so that the chest fixator can better serve the clinic and meet the needs of more patients. In addition, the U-shaped plate 301 is assembled by sliding through the inner side of the front waist side plate 5, which is convenient for the assembly of the entire fixator parts and improves the efficiency of assembly.

[0034] See also Figure 3 and Figure 6 The outer surface of the latch plate 302 is provided with an arrow mark 304, and the outer sides of the back patch plate 1 and the front chest patch plate 2 are provided with scale lines 309.

[0035] The setting of the arrow mark 304 provides the user with an intuitive visual guide when using it, so that when adjusting the positional relationship between the U-shaped plate 301 and the tooth plate 302, the corresponding position of the tooth can be quickly found to achieve precise adjustment, and the setting of the scale line 309 further improves the accuracy of the adjustment. The user can accurately adjust the rear waist side plate 4 and the front waist side plate 5 according to the width of the patient's upper body and refer to the indication of the scale line 309 to ensure that the fixator can fit the patient's upper body tightly and provide stable support and fixation effect. This design not only enhances the practicality and convenience of the fixator, but also improves its accuracy and reliability in clinical use.

[0036] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The back patch plate 1 is provided with a plurality of first through holes 101 , the bottom of the front chest patch plate 2 is provided with a plurality of waist-shaped cavities 201 , and the front chest patch plate 2 is provided with a plurality of second through holes 202 .

[0037] The setting of the first through hole 101 and the second through hole 202 allows air circulation, thereby improving the comfort of the patient when wearing it. The design of the waist-shaped cavity 201 not only increases the elasticity of the front chest plate 2, so that it can better fit patients of different body shapes, but also provides a certain buffer during the adjustment process, making the adjustment of the fixator smoother and less likely to cause a sense of oppression to the patient.

[0038] See also Figure 1 , Figure 2 and Figure 3 A neck support plate 6 is fixedly installed on the top of the front chest plate 2, and a long slide plate 602 is fixedly connected to the outer side of the neck support plate 6. A matching slide groove is opened on the top of the front chest plate 2, and a plurality of threaded holes 503 are opened on the rear side of the top position of the front chest plate 2.

[0039] The cooperation between the long slide plate 602 and the slide groove enables the neck support plate 6 to slide back and forth within a certain range, which is convenient for personalized adjustment according to the patient's neck position, ensuring that the neck support plate 6 can provide appropriate support for the patient. The threaded hole 503 is set for installing bolts. The user can rotate the bolt through the threaded hole 503 and press and fix it with the corresponding part on the long slide plate 602 to achieve fixation and fine-tuning of the position of the neck support plate 6. This design not only improves the adaptability and flexibility of the fixator, but also can better meet the patient's comfort and treatment needs.

[0040] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The rear waist side panel 4 is located at the center position and has a plurality of first line grooves 402 on its outer side surface, and a plurality of first long cavities 401 on its surface; the front waist side panel 5 is located at the center position and has a plurality of second line grooves 502 on its outer side surface, and a plurality of second long cavities 501 on its surface.

[0041] The first line groove 402 and the second line groove 502 are evenly distributed on the waist to avoid local compression and improve the comfort of the patient. The first long cavity 401 and the second long cavity 501 increase the elasticity and breathability of the rear waist side panel 4 and the front waist side panel 5, so that the fixator can fit the patient's waist while allowing air circulation to reduce the stuffiness. In addition, the design of these long cavities can also reduce the pressure of the fixator on the patient's waist to a certain extent, so that the patient can feel comfortable when wearing it for a long time.

[0042] See also Figure 2 and Figure 3 The central position of the inner side of the neck support plate 6 is provided with a number of grooves 601, the front chest plate 2 is located at the rear end of the slide groove 602 and is fixedly connected with four rectangular limiting convex plates 605, and the rear end surface of the curved plug plate 603 is fixedly connected with a number of reinforcing ribs 604.

[0043] These reinforcing ribs 604 enhance the structural strength of the curved insert plate 603. The setting of the groove 601 allows the neck support plate 6 to bend under a certain impact without being easily broken, and can buffer a certain bending impact force to prevent damage. The design of the limiting convex plate 605 can limit the neck support plate 6 from moving out of the slide groove 602, and can make the vertical upward or downward movement stable, not easy to bend and be damaged, thereby ensuring the stability of adjustment.

[0044] A plurality of hanging holes 702 are provided at the top of the front chest patch plate 2, the outer side of the rear waist side plate 4, the outer side of the front waist side plate 5 and the top of the neck support plate 6, each of which is provided with a clamping column 701, one end of which is fixedly connected to a hook 7, and a long through hole 703 is provided on the hook 7, and a long strip with Velcro on both sides is embedded inside.

[0045] One end of the long strap passes through the long through hole 703 on the hook 7 at the rear waist side panel 4, and the other end passes through the long through hole 703 on the hook 7 at the front waist side panel 5, and is fixed by Velcro. This design allows the entire fixator to be flexibly adjusted according to the patient's body shape and needs, ensuring that the fixator can fit the patient's chest and waist tightly to provide effective support and protection.

[0046] The back patch plate 1, the top of the front chest patch plate 2, the outer side of the rear waist side plate 4, the outer side of the front waist side plate 5 and the neck support plate 6 are all made of plastic material.

[0047] This plastic material is not only light, but also has good toughness and durability. It can withstand a certain amount of external force and pressure and is not easily deformed or broken. At the same time, the plastic material is easy to clean and disinfect, and meets the hygiene requirements of medical equipment.
