[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0024] See also Figures 1 to 5 As shown, an auxiliary fixation device for flail chest includes a fixing plate 1, a plurality of breathable mesh straps 2, a drug sustained-release layer 3 and an air bag 5. In this embodiment, the fixing plate 1 is a hard rectangular plate body, and the fixing plate 1 includes an outer side and an inner side. The inner side of the fixing plate 1 is used to fit the affected part of the patient to support the affected part of the patient and protect the affected part from secondary injury. Preferably, the fixing plate 1 is made of a memory alloy with a shaping function. Before use, the fixing plate 1 can be shaped into a shape suitable for the patient's bone morphology, so that the patient is more comfortable and firm when wearing it, and the fracture site is not allowed to shift at will.

[0025] A plurality of breathable mesh straps 2 are used to tie the fixing plate 1 to the patient, such as Figure 2 As shown, in this embodiment, there are four breathable mesh straps 2, and the four breathable mesh straps 2 are respectively fixed at the four corners of the outer wall of the fixing plate 1. During implementation, the breathable mesh straps 2 located on the opposite sides of the fixing plate 1 are respectively arranged along the two sides of the patient's body to the side of the patient away from the fixing plate 1, and then the free ends of the breathable mesh straps 2 on the opposite sides of the fixing plate 1 are fixed to each other to tie the fixing plate 1 to the patient. It should be noted that the method of fixing the free ends of the breathable mesh straps 2 to each other can use Velcro (not shown in the figure) in the prior art, for example, the breathable mesh strap 2 on one side is fixed with a fur surface, and the breathable mesh strap 2 on the other side is fixed with a hook surface, so that the two are fixedly connected, which will not be repeated here.

[0026] like Figure 1 As shown, the drug sustained-release layer 3 is fixed on the inner side wall of the fixed plate 1, and the drug sustained-release layer 3 is used for slowly releasing analgesics to alleviate the patient's pain and provide a continuous analgesic effect. Wherein analgesics include but are not limited to procaine, lidocaine, flurbiprofen, etc. In the present embodiment, the drug sustained-release layer 3 comprises an absorption pad for storing analgesics, and the absorption pad is made of cotton fiber or non-woven fabric. The staff can add analgesics in the absorption pad in advance, and then contact the patient's skin with the absorption pad, so as to slowly release the medicine, and absorb it through the skin to achieve the purpose of alleviating the patient's pain.

[0027] Furthermore, a connecting tube 8 for connecting to a pain-relieving pump is provided on one side of the drug-releasing layer 3, and one end of the connecting tube 8 is inserted into the inside of the drug-releasing layer 3. During implementation, the end of the connecting tube 8 away from the drug-releasing layer 3 can be connected to a pain-relieving pump (not shown in the figure), and the pain-relieving pump is used to periodically inject analgesics into the drug-releasing layer 3. Among them, the pain-relieving pump is a prior art, and can fill the drug-releasing layer 3 with liquid analgesics in a regular and quantitative manner to achieve a continuous analgesic effect and improve the patient's comfort.

[0028] like Figure 3 and Figure 4 As shown, in this embodiment, the drug sustained-release layer 3 is arranged in the middle of the inner wall of the fixing plate 1, and the outer edge of the fixing plate 1 close to the drug sustained-release layer 3 is coated with an adhesive layer 4 for bonding with the patient's skin to further firmly fix the fixing plate 1 on the patient's affected part to avoid displacement and falling off. Preferably, the adhesive layer 4 is a pressure-sensitive adhesive or a hot-melt adhesive.

[0029] The airbag 5 is arranged between the fixing plate 1 and the drug sustained-release layer 3 to provide the patient with better chest stability, reduce rib movement, and promote healing.

[0030] The airbag 5 is made of rubber or silicone. One side of the airbag 5 is connected to an inflation nozzle 6 for connecting to an inflation device (not shown in the figure). The free end of the inflation nozzle 6 passes through the fixed plate 1 and extends to the outside of the fixed plate 1. The inflation device can be an inflation pump or a manual inflation ball in the prior art, which will not be described in detail here. Preferably, there are multiple airbags 5, and one side of each airbag 5 is connected to an inflation nozzle 6.

[0031] When there is only one airbag 5, when it is inflated, the airbag 5 expands as a whole to evenly apply pressure to the affected part of the patient. This can avoid excessive local pressure and provide a more uniform support and fixation effect. When there are multiple airbags 5, each airbag 5 can be inflated separately, that is, the pressure of each airbag 5 area can be adjusted separately as needed, and then the inflation effect of each airbag 5 can be adjusted according to different conditions of the patient to improve comfort and flexibility.

[0032] Further, such as Figure 4 and Figure 5As shown, a non-return assembly 7 is provided in the inflation nozzle 6, and the non-return assembly 7 includes a first plug rod 71, a first plug head 72 and a first spring 73. The first plug rod 71 is arranged inside the inflation nozzle 6, and the axial direction of the first plug rod 71 is the same as the axial direction of the inflation nozzle 6. The first plug head 72 is fixed to the end of the first plug rod 71 away from the airbag 5, and is used to block the inflation nozzle 6, and one end of the first plug head 72 passes through the inflation nozzle 6 and extends to the outside of the inflation nozzle 6. The first spring 73 is sleeved on the outside of the first plug rod 71, and the two ends of the first spring 73 respectively abut against the first plug head 72 and the inner wall of the inflation nozzle 6 close to the airbag 5, so that the first plug head 72 moves to the side away from the airbag 5 and blocks the end of the inflation nozzle 6 away from the airbag 5.

[0033] During implementation, the staff uses an external inflation device to connect with the inflation nozzle 6 and inflate the inflation nozzle 6. When the gas pressure is greater than the elastic force of the first spring 73 of the non-return assembly 7, the gas can push the first plug 72 to move closer to the airbag 5. At this time, the first plug 72 no longer blocks the inflation nozzle 6, and the gas can enter the airbag 5 along the inflation nozzle 6. During the inflation process, the inflation amount of the airbag 5 is determined according to the actual situation and the patient's feedback, so as to improve the fixation effect and ensure the patient's comfort. When the gas in the airbag 5 reaches the preset value, the inflation is stopped. At this time, due to the elastic force of the first spring 73, the first plug 72 is reset and the inflation nozzle 6 is blocked again.

[0034] In addition, when it is necessary to decompress (deflate) the airbag 5, since one end of the first plug 72 passes through the inflation nozzle 6 and extends toward the outside of the inflation nozzle 6, the staff can push the first plug 72 protruding from the inflation nozzle 6 to move the first plug 72 toward the airbag 5. At this time, the first plug 72 no longer blocks the inflation nozzle 6, so the gas in the airbag 5 can be discharged, which makes it convenient for the staff to inflate or deflate the airbag according to the actual recovery condition of the patient.

[0035] During the specific implementation of the utility model, the staff takes out the fixing plate 1 and applies the inner side of the fixing plate 1 to the affected part of the patient. At this time, the adhesive layer 4 is bonded to the patient's skin. Since the fixing plate 1 is a plastic memory metal, the staff can adjust the shape of the fixing plate 1 in advance according to the bone morphology of the patient's affected part, so that the patient can wear it more comfortably, and then tie the breathable mesh strap 2 to the patient's body, and then inflate the airbag 5 according to the actual situation of the patient, and then pressurize and fix the patient's affected part. It should be noted that at this time, the drug sustained-release layer 3 and the patient's skin are connected, and the analgesic drug can be directly absorbed through the patient's skin to provide the patient with a continuous analgesic effect. Among them, the drug can be placed in the absorbent pad in advance or the connecting tube 8 of the pain pump can continuously provide the patient with analgesic drugs to relieve the patient's pain and improve the patient's comfort.

[0036] The utility model provides dual functions for patients through the airbag 5 and the drug sustained-release layer 3, which can not only relieve pain, but also stabilize the chest and promote the patient's recovery. By setting the airbag 5 to pressurize and fix the chest, the pressure can be adjusted according to the needs of the patient to reduce the movement of the damaged part and provide a more stable fixation effect; by setting the drug sustained-release layer 3 to contact the patient's skin, the drug is gradually released to provide the patient with a continuous analgesic effect, reducing the severe pain caused by flail chest.

[0037] The above description is only a preferred embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
