Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a protective isolation cover. Background Art

[0002] Exposure to aerosols and secretions from patients with respiratory diseases is a high-risk factor for infection among medical staff. Studies have shown that endotracheal intubation, sputum suction, nebulizer treatment, and operations performed through the mouth, such as oral surgery, will generate a large amount of aerosols and droplets. Compared with non-exposed persons, medical staff exposed to such high-risk operations have an infection rate that is 2.86 times higher.

[0003] In the prior art, some isolation covers are disclosed, such as protective bed covers, protective head covers, face masks, etc., which can effectively isolate patients and facilitate medical staff to treat patients. However, the prior art still has some shortcomings. For example, the existing isolation covers cannot effectively protect the patient's face (or face), especially for operations performed through the mouth, such as oral surgery in the dentistry department. A large amount of aerosols or liquid splashes are usually generated during the detection, surgery and treatment process, which will directly contaminate the patient's face and affect the patient's appearance, especially the appearance of female patients, and reduce the patient's medical experience. The existing isolation covers usually do not pay attention to this problem, and usually only consider how to isolate patients from medical staff, resulting in the existing isolation covers usually isolating patients or local areas of patients from the outside world, but cannot effectively protect patients, and are in urgent need of improvement. Summary of the invention

[0074] Example 3

[0075] In order to facilitate the patient to spit out liquid during oral surgery, the main difference between the present embodiment 3 and the above-mentioned embodiments 1 or 2 is that in the isolation cover provided in the present embodiment, the cover body 100 is further configured with an opening 108, and the opening 108 corresponds to the second opening 202 and is connected to the internal cavity 101, as shown in FIG. Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the opening 108 is configured at a position between the two operation holes 102 so as to correspond to the patient's oral cavity;

[0076] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, it also includes a cover 109, and the cover 109 is used to close the opening 108 and open the opening 108; in this embodiment, by constructing a special opening 108 on the cover body 100, the opening 108 can correspond to the patient's oral cavity to meet the patient's need to spit liquid during oral surgery, and by providing the cover 109 to open / close the opening 108, the opening 108 can be opened when needed, and the opening 108 can be closed after use to maintain the airtightness of the internal cavity 101.

[0077] In this embodiment, the cover 109 can be hinged to the cover body 100. Figure 5 or Figure 7 As shown, the lid 109 can be opened by rotating. Preferably, the upper portion of the lid 109 is hinged to the cover body 100.
