Abstract
The utility model provides a gas forced exhaust device, which comprises a telescopic air duct, a gas collecting cover, an air duct filter, a built-in air duct exhaust fan, an air valve and a damping arm, wherein the gas collecting cover is hermetically fixed at the front end of the telescopic air duct; the air forced exhaust device is used for forcibly exhausting air on the face of the patient in a short distance, and directly and effectively exhausting air exhaled by the patient to the negative pressure air duct, so that the diffusion of the air exhaled by the patient is avoided, and the safety of medical staff in short-distance patient inspection is guaranteed.
Description
Technical Field
The utility model belongs to the technical field of the negative pressure field of airing exhaust and specifically relates to an exhaust device is forced to gas.
Background
When medical staff are in close contact with patients during treatment and examination of critically ill respiratory infectious patients, particularly during facial examination, the air exhaled by the patients is easy to infect the medical staff. In order to strengthen self protection of medical care personnel, a device capable of effectively sucking away the exhaled gas of a patient with respiratory infection in a close range is developed, the probability of aerosol pollution in the process of examining the patient by the medical care personnel can be effectively reduced, and the device has very important clinical application value.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an exhaust device is forced to gas is provided.
In order to solve the technical problem, the technical scheme of the utility model is that:
the utility model provides an exhaust device is forced to gas, includes flexible wind channel (1), gas collection cover (3), air duct filter (7), built-in wind channel exhaust fan (8), blast gate (9) and damping arm (11), gas collection cover (3) is airtight fixed with flexible wind channel (1) front end, damping arm (11) and flexible wind channel (1) anterior segment department outer wall fixed connection, air duct filter (7) and built-in wind channel exhaust fan (8) are fixed in inside flexible wind channel (1) anterior segment department, blast gate (9) are fixed in inside flexible wind channel (1) back end straight segment department is equipped with blast gate switch (10) on this blast gate (9).
Preferably, in the forced air exhaust device, the gas collecting cover (3) is a transparent gas collecting cover.
Preferably, in the forced air exhaust device, an operating handle (6) is fixed to the gas collecting cover (3).
Preferably, in the forced air exhaust device, the operating handle (6) is provided with an illuminating lamp (4), and an illuminating switch (5) is fixed to the illuminating lamp (4).
Preferably, in the forced air exhaust device, the damping arm (11) is a universal damping arm.
Preferably, in the above air forced exhaust device, the air duct fan power supply (2) is disposed on the telescopic air duct (1).
The air forced exhaust device is arranged at the bedside of the sickbed according to the negative pressure exhaust principle, and the air valve (9) is closed at ordinary times; when the device is used, the air valve (9) is opened, the air duct fan power supply (2) is switched on, the gas collecting cover (3) is pulled to a suitable position on the face of a patient, the gas exhaled from the face of the infectious disease patient is effectively sucked away in a short distance through the built-in air duct exhaust fan (8) of the telescopic air duct (1), and the negative pressure air duct exhausted into the negative pressure ward is centrally and uniformly treated.
Has the advantages that:
above-mentioned exhaust device is forced to patient's face closely airs exhaust, directly effectively discharges the negative pressure wind channel to patient's expired gas, avoids patient's expired gas diffusion, guarantees the security when medical personnel closely inspect the patient.

Detailed Description
Example 1
As shown in fig. 1-2, the forced air exhaust device includes a telescopic air duct 1, a transparent air collection cover 3, an air duct filter 7, a built-in air duct exhaust fan 8, an air valve 9 and a universal damping arm 11, wherein an air duct fan power supply 2 is disposed on the telescopic air duct 1, the air collection cover 3 is hermetically fixed to the front end of the telescopic air duct 1, an operating handle 6 is fixed to the air collection cover 3 through bolts, an illuminating lamp 4 is disposed on the operating handle 6, an illuminating switch 5 is fixed to the illuminating lamp 4, the damping arm 11 is fixedly connected to the outer wall of the front section of the telescopic air duct 1, the air duct filter 7 and the built-in air duct exhaust fan 8 are fixed to the inside of the front section of the telescopic air duct 1, the air valve 9 is fixed to the inside of the rear section of the telescopic air duct 1, and the air valve switch 10 is disposed on the air valve 9.
The air forced exhaust device is installed at the bedside of a sickbed according to the negative pressure discharge principle, the rear end of the telescopic air duct 1 is communicated with an air duct in a wall body, the rear ends of the damping arms 11 are respectively fixed with the wall body, and the air valve 9 is in a closed state at ordinary times; when in use, the air valve 9 is opened, the air duct fan power supply 2 is switched on, the gas collecting cover 3 is pulled to a proper position on the face of a patient, the facial exhaled gas of the infectious patient is effectively sucked away in a short distance through the built-in air duct exhaust fan 8 of the telescopic air duct 1, and the exhausted gas is discharged to the negative pressure air duct in the negative pressure ward to be intensively and uniformly processed. The specific working process is as follows:
when in use, the air valve switch 10 and the built-in air duct exhaust fan 8 are turned on, the air collecting cover 3 is stretched to a proper position on the face of a patient through the operating handle 6, and the illuminating lamp 4 is turned on according to the situation. The forced air exhaust is carried out by the face of the patient in a close range, so that the air exhaled by the patient can be directly and effectively exhausted to the negative pressure air channel. When the air conditioner is not used, the telescopic air duct 1 is folded, the power supply 2 of the air duct fan is cut off, the built-in air duct exhaust fan 8 is closed, and the air valve switch 10 is closed. In addition, the air duct filter 7 is periodically cleaned and replaced.
