Description

Technical Field

[0001] The present invention relates to the technical field of medical appliances, and particularly relates to a head and face protection device for patients under general anesthesia in the prone position. Background Art

[0002] During the general anesthesia operation for patients undergoing lumbar and back surgery, they often need to maintain the prone position for a long time. After the patients are anesthetized, due to the loss of consciousness and the disappearance of related protective reflexes, it is very easy to cause local swelling, extrusion and other injuries to the head and face, resulting in unnecessary postoperative pain and reducing the medical experience. Therefore, the protection of patients, especially the protection of the head and neck, is particularly important during the body position change.

[0003] Most of the prone position pillows currently used clinically are single silicone soft pads, which often lack ergonomic designs, such as adjustable angles and facial fitting. The improvement methods adopted clinically mainly include applying soft pads on the forehead and mandible, and adjusting the head contact position every hour, etc. This not only increases the consumable cost additionally, but also increases the workload of anesthesiologists and nurses. Summary of the Invention

[0004] The purpose of the present invention is to provide a head and face protection device for patients under general anesthesia in the prone position, which can set a protective soft pad that fits on the patient's face, cooperate with a fixed skeleton for fixation, and set buffer inflatable air cushions on the forehead, cheek and mandible to further buffer and protect the local parts of the face. It is simple and convenient, reusable, and reduces the cost of disposable dressing consumables.

In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Please refer to Figure 1 and Figure 2 , a head and face protection device for prone position general anesthesia patients shown in a preferred embodiment of the present application includes a protective soft pad 1, a fixed skeleton 2 and a buffer inflatable air cushion 3. The protective soft pad 1 is attached to the patient's face, and the protective soft pad 1 has a forehead part 11, a cheek part 12 and a mandible part 13. The fixed skeleton 2 is arranged on the protective soft pad 1 and detachably sleeved on the patient's head for fixing the protective soft pad 1. The buffer inflatable air cushion 3 is detachably arranged on the forehead part 11, the cheek part 12 and the mandible part 13 of the protective soft pad 1 and is in contact with the facial skin for buffering and protecting the face.

[0030] According to the solution of the embodiment of the present invention, the protective soft pad 1 attached to the patient's face is fixed in cooperation with the fixed skeleton 2, and the buffer inflatable air cushion 3 is arranged on the forehead part 11, the cheek part 12 and the mandible part 13 to further buffer and protect the local parts of the face. It is simple and convenient, reusable, reduces the cost of disposable dressing consumables. At the same time, this device can be used together with existing silicone brackets, sponge brackets or brackets designed in other ways.

[0031] The following will be described in detail with specific embodiments:

[0032] Please refer to Figure 2 , the buffer inflatable air cushion 3 has a honeycomb structure. The buffer inflatable air cushion 3 is composed of a plurality of honeycomb units 31, and a flexible film 32 for isolation is arranged between adjacent honeycomb units 31. Each honeycomb unit 31 is an independent small air chamber isolated by the flexible film 32. The honeycomb arrangement can ensure that the pressure can be dispersed between the honeycomb units 31, distribute the pressure to a larger contact area, and maintain the overall structural stability, while the flexible film 32 enables the pressure to be adaptively adjusted according to the concave and convex shape of the face.

[0033] Specifically, the diameter of the honeycomb unit 31 is about 5-10 mm (which can be optimized according to the application), and the flexible film 32 is made of a flexible polymer material such as medical silicone or TPU with good elasticity, durability and compressive performance.

[0034] Further, the honeycomb cells 31 are divided into two groups. One group of honeycomb cells 31 is used for inflation, and the other group of honeycomb cells 31 is used for deflation. Microchannels for connection are provided between multiple honeycomb cells 31 within the same group. Two micro air pumps or two manual inflation and deflation interfaces are provided at the buffer inflatable air cushion 3. The two micro air pumps or the two manual inflation and deflation interfaces are correspondingly connected to the two groups of honeycomb cells 31 to form two inflation and deflation systems. By setting the two inflation and deflation systems to cooperate with each other, local area inflation and local area deflation of the buffer inflatable air cushion 3 can be alternately carried out. In this way, while maintaining the buffer protection of the patient's facial area, a certain recovery time can be given to the skin of the local area of this facial area, avoiding discomfort caused by long-term skin compression.

[0035] It should be noted that in this embodiment, the four buffer inflatable air cushions 3 provided at the forehead 11, the cheeks 12, and the lower jaw 13 are detachably connected as a whole through ventilation hoses. In this way, the four buffer inflatable air cushions 3 can be inflated and deflated simultaneously using two micro air pumps or two manual inflation and deflation interfaces, saving equipment costs. At the same time, the buffer inflatable air cushion 3 is detachably arranged on the protective soft pad 1 through Velcro, facilitating position adjustment according to the facial sizes of different patients.

[0036] A replaceable antibacterial coating is provided at the bottom of the buffer inflatable air cushion 3 to avoid infection caused by long-term skin contact.

[0037] A micro air pump or a manual inflation and deflation interface is provided at the buffer inflatable air cushion 3. When the patient's face moves slightly, the gas flow in the buffer inflatable air cushion 3 can buffer the pressure change, avoiding local pressure concentration. Microchannels are formed between the honeycomb cells 31, and a small amount of air can be pumped to promote local ventilation, reducing skin dampness and stuffiness. After the device is used for a long time, the gas in the buffer inflatable air cushion 3 can be released by a short-term decompression method to give the skin a recovery time.

[0038] A pressure sensor and a humidity and temperature sensor are embedded in the buffer inflatable air cushion 3 to monitor the pressure and environment in contact with the face in real time. The monitoring data can be uploaded to the surgical monitoring system to remind medical staff to adjust the inflation and deflation of the buffer inflatable air cushion 3 according to needs.

[0039] Please refer to Figure 1 , the fixed frame 2 is provided with a fixing buckle 21 for wearing and taking off at the lower jaw 13, facilitating the wearing and taking off of the fixed frame 2 and the protective soft pad 1.

[0040] Please refer to Figure 1 , an avoidance groove 22 is provided at the fixed frame 2 near the cheeks 12. The avoidance groove 22 is used to avoid tracheal catheters and other pipelines, avoiding pipeline bending.

[0041] Please refer to Figure 1, a connecting part 14 is provided on the protective cushion pad 1, and the connecting part 14 is used for detachably connecting with the fixed skeleton 2.

[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0043] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
