Description

Technical Field

[0001] The invention belongs to the field of parotid gland pressing devices, and in particular relates to an adjustable parotid gland pressurizing and positioning device. Background Art

[0002] Patients undergoing surgery for the parotid gland, preauricular fistula, or submandibular gland often require a pressure bandage. This bandage utilizes external mechanical pressure to secure the flap to the underlying tissue, causing the remaining alveoli to atrophy and lose their secretory function. This prevents the development of salivary fistulas. Applying a pressure bandage to the parotid gland eliminates dead space, prevents fluid accumulation and infection, and acts as a hemostatic agent, thereby ensuring optimal wound healing.

[0003] Existing parotid gland compression devices require a bandage to be placed around the mandible to secure the compressed gauze to the parotid gland. However, the patient's mandibular joint often moves due to talking and eating, which can cause the bandage to compress the mandible, causing abrasion, redness, and swelling of the submental skin. The bandage can also loosen easily, resulting in poor compression effectiveness and complications such as salivary fistulas and parotid fistulas. To address these issues, the development of a parotid gland compression fixation device that does not damage the mandible and allows for adjustable pressure and area is highly desirable.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention provides an adjustable parotid gland pressure positioning device, which uses a back neck support to support the patient's neck without passing through the user's mandible, will not affect the user's mandibular movement, and will not cause wear and swelling to the patient's mandibular skin. This device can be reused, which will save a lot of resources, reduce the amount and time of bandages consumed during parotid gland pressure bandaging and replacement, and avoid the generation of medical waste; through the coordinated use of a fixed sleeve, a screw and a cheek pressure air cushion, the pressure of the pressurized air bag on the parotid gland affected area is adjusted, and the incidence of complications caused by insufficient pressure is reduced. At the same time, it can also avoid the occurrence of discomfort in the patient's compressed part caused by excessive pressure; the multi-stage connecting rod, the adjustment rod and the cheek pressure air cushion unit of interchangeable size not only enhance stability, but also have a wider range of applications and are more in line with the needs of different users.

[0019] 2. The present invention provides an adjustable parotid gland pressure positioning device, in which the cheek compression air cushion unit is replaceable. The appropriately sized air cushion can be selected according to the parotid gland size of patients of different age groups to ensure the accuracy of cheek compression. The length and bending angle of the cheek compression support component of the device can be adjusted to facilitate accurate cheek compression. At the same time, the distance between the two cheek compression components can also be adjusted accordingly, which can provide accurate cheek compression for patients with different face shapes or elderly patients with unilateral cheek sunkenness.

[0020] 3. The present invention provides an adjustable parotid gland pressure positioning device, in which the neck support component and the two cheek pressure adjustment components are detachably connected to the base, and can be disassembled and stored when the device is idle, and spliced ​​and assembled when the device is in use, which greatly saves the space occupied by the entire device when stored. Especially in an environment with limited and tight space such as a hospital, multiple devices can be accommodated in a unit space at the same time through disassembly and storage, greatly improving the space utilization rate of the hospital.

[0021] 4. The present invention provides an adjustable parotid gland pressurizing and positioning device, in which the distance between each cheek pressure adjusting component can be individually adjusted according to the patient's face shape, especially for elderly patients with muscle atrophy and patients with long-term hemiplegia. The characteristics of such patients are that due to the influence of age and their own diseases, their facial and neck muscles are difficult to ensure symmetry. When using a traditional pressurizing device to pressurize the artery, since the pressurization method relies on the elastic force of the strap to achieve synchronous pressurization at both ends, the symmetry requirements on both sides of the face are high. For patients with facial muscle atrophy on one side and fuller muscles on the other side, it is easy to cause insufficient pressure on both sides during use, thereby affecting the pressurization effect. The present application can adjust the distance between the unilateral cheek pressure component and the patient by adjusting the position of each cheek pressure adjusting component inserted into the base, so that the cheek pressure component is more suitable for patients with different face shapes, thereby achieving a better cheek pressure effect.

[0055] How it works

[0056] When the present invention is used, the patient's neck is first placed on the air cushion group 3 placed on the arc surface of the arc support plate 2. The air cushion group 3 is ventilated to make the air cushion bulge to achieve the effect of stable support. After the support is stable and the patient feels comfortable, the air inlet 14 is plugged with a sealing plug to ensure the air tightness of the air cushion to prevent air leakage. The distance between the multi-stage connecting rod 5 and the arc support plate 2 is adjusted by pushing each rack 4 inside the base 1. Each rack 4 can be pushed and adjusted separately according to the patient's face shape. This adjustment will It better caters to the cheek contour and improves the patient's comfort. After the position of the cheek pressure adjustment component is adjusted, the rack 4 is locked and limited by the limiting wedge 15 and the No. 1 return spring 16. By bending the multi-stage connecting rod 5 and pulling the sliding distance of the adjusting rod 6 on the multi-stage connecting rod 5, the cheek pressure component can accurately press the patient's cheeks. By screwing the adjusting screw 8, the adjusting screw drives the adjusting seat 9 and the cheek pressure air cushion on the adjusting seat 9 to approach the patient's cheeks and press them tightly, thereby achieving the purpose of this device.
