Description

Technical Field

[0001] The invention relates to the technical field of negative pressure wards, and in particular to a self-adaptive negative pressure ward with negative feedback regulation. Background Art

[0002] Negative pressure ward refers to a ward with a special device, where the air pressure inside is lower than the air pressure outside the ward. In this way, in terms of air circulation, only fresh air from outside can flow into the ward, and the air contaminated by the patient in the ward will not leak out, but will be discharged to a fixed place in time through a special channel. In this way, the place outside the ward will not be polluted, thereby reducing the chance of medical staff being infected in large numbers. This ward is most suitable for rescuing patients with respiratory infectious diseases. Infectious disease negative pressure isolation wards use one set of air supply purification devices and two sets of exhaust purification devices. The air supply purification device consists of an air supply cabinet and primary, medium and high efficiency filter devices, and the exhaust purification device consists of an exhaust cabinet and coarse and medium efficiency filter devices. The functions of the infectious disease negative pressure isolation ward mainly have two points. One is to use the negative pressure principle to isolate pathogenic microorganisms, and at the same time, the indoor air contaminated by the patient is discharged after special treatment, which will not pollute the environment; the second is to dilute the concentration of pathogenic microorganisms in the ward through ventilation and reasonable airflow organization, and put medical staff in a favorable wind direction section to protect the work safety of medical staff.

[0003] When the ventilation system of a negative pressure ward fails, large air pressure changes will occur in the negative pressure ward, which can easily cause discomfort to patients in the negative pressure ward. However, it is difficult for existing negative pressure wards to adaptively adjust the air pressure according to the negative pressure in the negative pressure ward, and the air entering the negative pressure ward through adaptive adjustment is likely to contain bacteria, which may cause the patient's condition to worsen. Summary of the invention

[0004] In view of the shortcomings of the existing problems, the present invention provides an adaptive negative pressure ward with negative feedback regulation to solve the existing problems raised in the above background technology.

[0005] To solve the above problems, the present invention is implemented through the following technical solutions: an adaptive negative pressure ward with negative feedback regulation, comprising a negative pressure ward main body, an air purification box is arranged outside the negative pressure ward main body, a first ventilation pipe and a second ventilation pipe are arranged on the outer surface of the air purification box, an adaptive adjustment device is arranged inside the first ventilation pipe, a limited position frame is fixedly connected to the inner surface of the air purification box, a mounting frame is arranged inside the limited position frame, a high-efficiency filter is arranged inside the mounting frame, an ultraviolet sterilization lamp is fixedly connected to the inner wall of the air purification box, a power storage module is arranged on the top of the inner surface of the air purification box, a solar panel is arranged on the upper surface of the air purification box, the adaptive adjustment device comprises a fixing seat, an inner groove is arranged inside the fixing seat, a connecting guide rod is sleeved inside the inner groove, a movable shell is fixedly connected to the end of the connecting guide rod, a ventilation hole is arranged in the middle of the fixing seat, and a telescopic spring is sleeved on the outer surface of the connecting guide rod.

[0007] Preferably, the second ventilation duct is arranged above the first ventilation duct, and the ultraviolet sterilization lamp and the solar panel are both electrically connected to the power storage module.

[0008] Preferably, a limiting convex strip is provided on the top of the installation frame, a guide slot is provided on the top of the inner surface of the limiting frame, the outer surface of the limiting convex strip is matched with the inner surface of the guide slot, and the high-efficiency filter is provided at the end of the first ventilation duct.

[0009] Preferably, the outer surface of the air purification box is provided with a mounting groove, the outer surface of the mounting frame is adapted to the interior of the mounting groove, and the outer surface of the mounting frame is fixedly connected with a handle.

[0010] Preferably, the outer surface of the fixing seat is fixedly connected to the inner surface of the first ventilation pipe, and the inner surface of the ventilation hole is matched with the outer surface of the movable shell.

[0011] Preferably, one end of the connecting guide rod away from the movable shell is fixedly connected to a connecting plate, and the internal groove, the connecting guide rod, the connecting plate and the telescopic spring are symmetrically arranged on both sides of the ventilation hole.

[0012] Preferably, the end of the telescopic spring is fixedly connected to the outer surface of the connecting plate, and the end of the telescopic spring away from the connecting plate is fixedly connected to the inner surface of the inner groove.

[0013] The present invention provides a self-adaptive negative pressure ward with negative feedback regulation, which has the following beneficial effects:

[0014] 1. The adaptive negative pressure ward with negative feedback regulation, through the adaptive regulation device, under the action of the pressure difference between the inside and outside of the negative pressure ward, a gap is generated between the movable shell and the ventilation hole of the fixed seat, and air enters from the gap to regulate the air pressure in the negative pressure ward. The size of the gap depends on the pressure difference between the inside and outside of the negative pressure ward, and the function of adaptive regulation according to the air pressure in the negative pressure ward is realized, so that in the event of a failure of the ventilation system, it is not easy to produce a large pressure change in the negative pressure ward, thereby preventing a large impact on the patient, and under the pull of the elastic force of the telescopic spring, the degree to which the ventilation hole is opened is limited to a maximum, which can prevent excessive air from entering the negative pressure ward in a short period of time and causing unstable air pressure in the negative pressure ward, thereby ensuring stable regulation of air pressure.

[0015] 2. The adaptive negative pressure ward with negative feedback regulation, through the cooperation among the air purification box, the first ventilation duct, the second ventilation duct, the ultraviolet sterilization lamp and the high-efficiency filter, ensures that the air is first filtered of dust and other impurities by the high-efficiency filter before entering the negative pressure ward, and then sterilized by the ultraviolet sterilization lamp, thereby ensuring that dust-free and sterile air enters the negative pressure ward to prevent impurities and bacteria in the air from worsening the patient's condition, and the high-efficiency filter is set to a detachable structure, and the high-efficiency filter can be taken out for cleaning or replacement regularly to ensure that the high-efficiency filter has an efficient filtering effect.

[0026] The first ventilation duct 3 and the second ventilation duct 4 are arranged on both sides of the air purification box 2. The outer surface of the second ventilation duct 4 passes through the negative pressure ward body 1 and extends to the inside. The insides of the first ventilation duct 3 and the second ventilation duct 4 are both connected to the inside of the air purification box 2.

[0027] The second ventilation duct 4 is disposed above the first ventilation duct 3 , and the ultraviolet sterilization lamp 13 and the solar panel 15 are both electrically connected to the power storage module 14 .
