Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an ICU mobile isolator. Background Art

[0002] ICUs gather critically ill patients and provide the best support in terms of manpower, material resources and technology in order to achieve good treatment results. Currently, many infectious diseases can be directly transmitted through the air. Some of these infectious diseases have extremely strong transmission capabilities and are very harmful to the human body. Patients with such diseases must be quickly isolated and treated. Therefore, a mobile isolator or mobile isolation bed has been proposed in the prior art.

[0003] For example, the Chinese patent application number CN202020203127.4 discloses a negative pressure ventilation medical isolation bed, which relates to the field of medical care beds. The outer side of the anti-leakage filter sponge is provided with corner guards, the left and right sides of the push-pull isolation cover are provided with oxygen supply ports, infusion ports and additional operation ports, the upper part of the push-pull isolation cover is provided with additional ports, the front and rear ends of the push-pull isolation cover are respectively provided with negative pressure exhaust ports and filter air inlets with protective covers, and the bottom of the bed is provided with a vacuum negative pressure control system, which is connected to the push-pull isolation cover. Under the action of the protective cover, medical staff will not come into contact with the patient and be infected. Patients and medical staff will not share untreated gas, and cross infection will not occur. The negative pressure cover can ensure sufficient oxygen use, which is hygienic and safe, and can isolate and disinfect pathogens more thoroughly. The ultimate goal of the negative pressure ventilation medical isolation bed is to collect and treat harmful air in a centralized manner to avoid infection.

[0004] However, when negative pressure is used to replace the gas in the isolation bed, uneven airflow will be generated in the isolation bed, which may cause local airflow impact. Even the rapid flow of airflow may create a vacuum area on the patient's face, causing breathing discomfort. Therefore, the existing technology for replacing the gas in the isolation space has the problem of easily causing breathing discomfort to the patient. Utility Model Content

This facilitates the regular partial extraction of polluted gas generated by breathing in the isolation cabinet 200 and the injection of fresh air therein, thereby replacing the gas in the isolation cabinet 200 and avoiding discomfort to the patient caused by excessive concentration of polluted gas in the isolation cabinet 200. The partition 300 separates the gas replacement process from the patient's breathing, avoiding interference with the patient's breathing when extracting polluted air or injecting fresh air.

[0036] Please refer to Figures 1 to 5 , an ICU mobile isolator, comprising a base 100;

[0037] Four rollers 101 arranged in a rectangular shape are mounted on the lower end surface of the base 100;

[0038] An internally hollow isolation cabinet 200 is fixed to the upper end of the base 100. The peripheral wall of the isolation cabinet 200 is open on either side. A pair of symmetrically placed cabinet doors 201 are provided at the open ends of the isolation cabinet 200. The cabinet doors 201 are rotatably hinged to the isolation cabinet 200 through hinges.

[0039] A horizontally placed partition 300 is provided in the isolation cabinet 200. The peripheral wall of the partition 300 is in close contact with the inner peripheral wall of the isolation cabinet 200 and has good airtightness. A plurality of evenly distributed air holes 301 are opened on the partition 300. A blocking assembly 400 is provided on the partition 300 for sealing each air hole 301. A drive assembly connected to the partition 300 and used to drive the partition 300 to move up and down is provided in the isolation cabinet 200.

[0040] The base 100 is further provided with an exhaust assembly 600. When the sealing assembly 400 seals the vent 301, the exhaust assembly 600 is used to extract the gas above the partition 300 in the isolation cabinet 200 out of the isolation cabinet 200.

[0041] A blower 700 is fixed directly above the isolation cabinet 200. The input end of the blower 700 is exposed outside the isolation cabinet 200, and the output end of the blower 700 is connected to the upper part of the partition 300 inside the isolation cabinet 200.

[0043] The partition 300 is usually made of a durable, easy-to-clean material, such as stainless steel, aluminum alloy, polycarbonate or other medical-grade plastics; the peripheral wall of the partition 300 should be smooth, and a wear-resistant coating should be added to its surface to improve its durability.

[0044] The blower 700 is usually designed as a centrifugal or axial flow type to introduce fresh air from the outside into the isolation cabinet 200; the housing of the blower 700 is usually made of stainless steel or other easy-to-clean, corrosion-resistant materials, which helps to ensure hygiene standards and extend the life of the blower 700.

[0045] The patient lies flat in the isolation cabinet 200, the partition 300 is located above the patient, and the air vents 301 are initially open; after the patient has been in the isolation cabinet 200 for a period of time, the driving component is turned on to move the partition 300 downward until it is close to the patient, and then the blocking component 400 is turned on to seal the air vents 301; then the exhaust component 600 is turned on to extract the air above the partition 300 out of the isolation cabinet 200; when the air above the partition 300 is evacuated, the blower 700 is turned on to inject fresh air into the part above the partition 300 in the isolation cabinet 200. After the fresh air is injected, the air vents 301 are opened again by the blocking component 400, and at the same time, the partition 300 is driven upward by the driving component to allow the fresh air above to pass through the air vents 301 to the bottom of the partition 300;

[0046] Repeating the above operation at regular intervals allows for the regular partial extraction of dirty gas generated by breathing in the isolation cabinet 200 and the injection of fresh air therein, thereby achieving replacement of the gas in the isolation cabinet 200 and avoiding discomfort to the patient due to excessive concentration of dirty gas in the isolation cabinet 200.

The number of rows of the blocking strips 402 and the vents 301 is equal and corresponds one to one. A mounting block 4031 is fixed to the upper end of the partition 300. The mounting block A second telescopic cylinder 403 is fixed on 4031 and is placed coaxially with the connecting strip 401. The output end of the second telescopic cylinder 403 is fixed to any blocking strip 402 through a connecting block. The second telescopic cylinder 403 drives the blocking strip 402 and the connecting strip 401 to move. When the blocking strip 402 moves to the top of the corresponding row of air holes 301, the blocking strip 402 can seal the row of air holes 301. When the blocking strip 402 is removed, the air holes 301 can be opened.
