Problems solved by technology

Due to the high cost of construction and maintenance, the number of wards with such conditions is limited, which can only meet the treatment needs of sporadic and severe respiratory infectious diseases with a small number of infections.
[0003] However, due to the high infectivity and spreading ability of some respiratory infectious diseases, it poses new challenges to modern medical protection measures
Existing qualified medical facilities cannot meet the requirements for timely admission and treatment of surge patients, which has caused a serious run on medical resources
Not only that, in the process of treating patients, the infectious gas exhaled by the patients continues to spread in the ward, making the whole room permeated with harmful pathogens, and medical staff working in this environment bear a greater risk of infection

Embodiment example A

[0048] The operating steps of the biological aerosol negative pressure barrier device for respiratory infectious diseases involved in the present invention are as follows:

[0049] (1) The patient lies flat on the nursing bed.

[0050] (2) Arrange a gear bracket 1.1 on the bed bodies on the left and right sides near the patient's head and neck.

[0051] (3) Hold the pulling lever 1.1.9 on the gear bracket 1.1 tightly, so that the current height-fixing groove of the height-adjusting latch 1.1.6 and the gear column 1.1.5 is released.

[0052] (4) Lift the height adjustment keel 1.1.2 to rise or fall, and find the height gear that meets the patient's body requirements.

[0053] (5) Loosen the pulling lever 1.1.9 on the gear bracket 1.1, so that the height-adjusting latch 1.1.6 is reconnected with the current fixed height concave of the gear column 1.1.5 under the restoring force of the return spring 1.1.7. slot locked.

[0054] (6) Adjust the height of the height-adjusting kee...

Embodiment example B

[0060] The specific working principle of the gear bracket 1.1 involved in the present invention is as follows when in use:

[0061](1) Press and pull the grip bar 1.1.9, so that the pulled grip bar 1.1.9 moves downward in the grip bar slideway 1.1.2.6.

[0062] (2) Pull the grip bar 1.1.9 to drive the left and right two power transmission soft ropes 1.1.8 connected to it to move along the power transmission slideway 1.1.2.5 and the corner baffle 1.1.2.4 respectively.

[0063] (3) The left and right height-adjusting latches 1.1.6 correspondingly connected to the two force-transmitting soft ropes 1.1.8 move along the latch slideway 1.1.2.2 to the direction corresponding to the isolation baffle 1.1.2.3, and compress The back-moving spring 1.1.7 connected with it makes it accumulate the elastic energy needed for reset.

[0064] (4) After the height-adjusting latch 1.1.6 has completely withdrawn from the lifting slideway 1.1.2.1, the height-adjusting keel 1.1.2 can be lifted up or...

Abstract

The invention provides a biological aerosol negative pressure blocking device for respiratory infectious diseases, and belongs to the field of medical instruments. The mask solves the problem of how to obstruct, capture, filter and kill infectious droplet aerosol generated by breathing of a patient in time, improves the use comfort of the patient, and relieves local pain and swelling feeling generated by long-time wearing of a traditional mask. A mask system of the device is placed on a nursing sickbed and located above the head and neck of a patient, a fan system is connected with the mask system, and a filtering and disinfecting system receives infectious droplet aerosol from the fan system and is responsible for disinfecting and filtering harmful substances in the infectious droplet aerosol. The distance between the mask and the mouth and the nose of a patient can be adjusted according to the figure of the patient, the actual requirements of different people are met, meanwhile, the use comfort of the patient is improved through the non-contact use mode, and local pain and swelling feeling generated after a traditional mask is worn for a long time are effectively reduced.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a bioaerosol negative pressure barrier device for respiratory infectious diseases. Background technique [0002] Droplets and aerosols are one of the main ways of spreading respiratory infectious diseases. At present, the main ways for hospitals to deal with infectious droplet aerosols produced by patients' breathing include wearing masks for patients, keeping the environment ventilated, and cleaning and disinfecting regularly. For severe respiratory infectious diseases, it is necessary to further adopt methods such as adding negative pressure wards and wearing isolation suits to avoid the spread of severe viruses and reduce the risk of personnel infection. Due to the high cost of construction and maintenance, the number of wards with such conditions is limited, which can only meet the treatment needs of sporadic and severe respiratory infectious diseases with a small number of in...
