Description

Technical Field

[0001] The utility model relates to the technical field of production of medical auxiliary instruments, in particular to a wound fixing device for the postoperative parotid region. Background Art

[0002] The dressing of the oral and maxillofacial region, especially after parotidectomy, has always been a technical problem. At present, the dressing method of using a bandage and a gauze pad is still commonly used in China. There are mainly two difficult problems that are difficult to break through in this dressing:

[0003] First, the problem of uncontrollable pressure, which completely depends on the personal feeling of medical staff and there is no unified scientific quantification standard. Both excessive and insufficient pressure can lead to corresponding serious complications;

[0004] Second, due to the large number of organs in the maxillofacial region and the uneven shape compared with the limbs, the dressing of this area requires certain technical requirements and is more complex than the dressing of other areas. It is not easy for beginners to master, especially it is more difficult to achieve an ideal and rapid maxillofacial dressing in case of emergency. Moreover, due to the large amount of hair on the head, especially for women, the bandage is easy to loosen after dressing. After parotidectomy, the loosening of the dressing in the parotid region is extremely likely to cause adverse reactions such as salivary fistula and hematoma after surgery, and even some may cause permanent sequelae to the patient. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wound fixing device for the postoperative parotid region to solve the above problems.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A wound fixing device for the postoperative parotid region includes a mesh sleeve with a window, and a perforated edge is arranged on the mesh sleeve. There are two groups of the perforated edges, which are arranged around the center of the window, and the number of the perforated edges in each group is not less than four;

[0008] It further includes two maxillofacial negative pressure plate members, and the maxillofacial negative pressure plate members are divided according to the structure into:

[0009] A vertical part passing through between a plurality of the perforated edges in each group;

[0010] A horizontal part connected to one end of the vertical part, and a plurality of equally spaced perforations are formed in one of the horizontal parts, and convex points inserted and combined with the perforations are fixedly arranged on the other horizontal part.

[0011] Preferably, the maxillofacial negative pressure plate member is a rigid plastic member.

[0012] Preferably, the mesh cover is of a double-layer structure, and an airbag block is arranged between the two layers. There are eight airbag blocks in total, four in each group, and they are arranged at the location of the vertical part.

[0013] Preferably, a rubber one-way air nozzle is arranged on the mesh cover, and the rubber one-way air nozzle is communicated with the airbag block through a hose.

[0014] In the above technical solution, a postoperative wound fixing device for the parotid region provided by the present utility model has the following beneficial effects: the maxillofacial negative pressure plate member applies negative pressure to the inflated airbag block, thereby forming negative pressure on the parotid region.

[0021] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail with reference to the drawings.

[0022] As Figures 1 - 3 shown, a postoperative wound fixing device for the parotid region includes a mesh cover 1 having a window 11. A perforated edge 2 is arranged on the mesh cover 1. There are two groups of perforated edges 2, which are arranged symmetrically about the center of the window 11, and the number of perforated edges 2 in each group is not less than four;

[0023] It further includes two maxillofacial negative pressure plate members 3, and the maxillofacial negative pressure plate members 3 are divided according to the structure into:

[0024] The vertical part 31 is arranged between multiple perforated edges 2 in each group;

[0025] The horizontal part is connected to one end of the vertical part 31. A plurality of perforations 4 are arranged at equal intervals on one of the horizontal parts, and bumps 5 inserted and combined with the perforations 4 are fixedly arranged on the other horizontal part.

[0026] When in use, the mesh cover 1 is worn in from the head, and then the face is exposed through the window 11. Then, according to the shape of the patient's face, the positions of the bumps 5 and the perforations 4 are adjusted, so that the length formed by the combination of the two horizontal parts is equal to the length of the patient's forehead. Then, the vertical part 31 is alternately arranged through the multiple perforated edges 2 at equal intervals on both sides, as Figure 1 shown.

[0027] Furthermore, the mesh cover 1 in the embodiment is of a double-layer structure, and an airbag block 6 is arranged between the two layers. There are a total of eight airbag blocks 6, four in each group, and they are arranged at the position where the vertical part 31 is located.

[0028] And a rubber one-way air nozzle 7 is arranged on the mesh cover 1. The rubber one-way air nozzle 7 is communicated with the airbag block 6 through a hose. The injection is connected to the rubber one-way air nozzle 7, and then the airbag block 6 is inflated through the hose to achieve negative pressure in the parotid region. When deflation is required, deflation can be completed by piercing the rubber one-way air nozzle 7 with a hard object.

[0029] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
