Embodiment 1

[0052] see Figure 1-Figure 5 In this embodiment, a protective isolation cover is provided, including a cover body 100 made of a light-transmitting material, and an isolation film 200 connected to the cover body 100 and used to close the cover body 100. The cover body 100 and the isolation film 200 Together to form a closed internal cavity 101, the isolation membrane 200 is configured with a first opening 201 for nose breathing, the first opening 201 is used to pass through the patient's nose so that the patient breathes, the first opening 201 The shape can be adapted to the shape of the human nose;

[0053] The isolation membrane 200 is also configured with a second opening 202 corresponding to the oral cavity, that is, the second opening 202 is used to cover the patient's oral cavity, and the cover body 100 is provided with at least one operation hole 102, and the operation hole 102 is connected to the patient's mouth. The internal cavity 101 is connected so that medical in...

Embodiment 2

[0071] The main difference between this embodiment 2 and the above-mentioned embodiment 1 is that this embodiment does not adopt the method of setting the through hole 106 and setting the filter layer for the patient to breathe, because the isolation cover provided by this embodiment also includes a breathing mask 401 and Connecting pipe 402, such as Figure 6 and Figure 7 As shown, the cover body 100 is provided with a communication hole 107, and the internal cavity 101 is provided with a breathing mask 401, and the breathing mask 401 is fixed to the isolation membrane 200 and connected to the first opening 201. One end of the communication tube 402 communicates with the breathing mask 401, and the other end communicates with the communication hole 107, so that the nose of the patient wearing the isolation mask can pass through the breathing mask 401 and the communication tube 402. communicate with the outside world so that the patient can breathe normally;

[0072] For pa...

Embodiment 3

[0075] In order to facilitate the patient to spit liquid during oral surgery, the main difference between this embodiment 3 and the above-mentioned embodiment 1 or 2 is that in the isolation cover provided by this embodiment, the cover body 100 is also configured with an opening 108. The opening 108 corresponds to the second opening 202 and communicates with the inner cavity 101, as 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] Such as figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, a cover 109 is also included, and the cover 109 is used for closing the opening 108 and opening the opening 108; Satisfy the patient's need to spit liquid during oral surgery, and set the cover 109 to open / close the opening 108, so that the opening 108 can be opened when needed, and the opening 108 can be closed after use to maintain...

Abstract

The invention relates to a protective isolation hood. The hood comprises a hood body and an isolation film connected with the hood body and used for sealing the hood body, the hood body and the isolation film jointly define a closed internal cavity, and the isolation film is provided with a first opening for nose breathing and a second opening corresponding to an oral cavity; and the hood body isprovided with an operation hole, the operation hole is in communication with the internal cavity, the operation hole is provided with an isolation protection member used for opening / closing, the isolation film is used for being attached to the face of a patient, and the hood body is used for covering the face of the patient so that the internal cavity can be in connection and communication with the oral cavity of the patient. According to the isolation hood, medical staff can conveniently treat the patient through the oral cavity, in the treatment process, the face of the patient can be effectively isolated and protected, the face of the patient is prevented from being polluted, the makeup of the patient is prevented from being scratched, aerosol, splashed secreta and the like can be effectively isolated, the problems that the aerosol pollutes the environment, and iatrogenic infection occurs are solved, and the hood is especially suitable for oral surgery in the stomatology department.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a protective isolation cover. Background technique [0002] Aerosol and secretion splash exposure of patients with respiratory diseases are high risk factors for infection among medical staff. Studies have shown that endotracheal intubation, sputum suction, nebulizer therapy, and operations performed through the mouth, such as oral surgery, will produce a large amount of aerosols and droplets. Medical staff exposed to such high-risk operations and non-exposed people Compared with that, the infection rate increased by 2.86 times. [0003] In the prior art, some isolation covers are disclosed, such as protective bedspreads, protective hoods, face masks, etc., which can effectively isolate patients and facilitate medical staff to treat patients. However, there are still some deficiencies in the prior art. For example, the existing isolation cover cannot effectively protect...
