Ventilation device used in medical room

Abstract

The invention provides a ventilation device used in a medical room, relates to the field of medical ventilation equipment. The problems that the maximum contact between wind and a filter element cannot be guaranteed, moreover, in most existing devices, a fan is driven to ventilate through a motor, a computer needs to be consumed for ventilation, and the maintenance period is short are solved. Theventilation device used in the medical room comprises a box body; a rotating shaft is rotatably connected to the box body of the ventilation device used in the medical room, and a cylindrical fan is fixedly connected to the rotating shaft. Due to the arrangement of a blocking block, when wind enters a filter element box with a cylindrical structure and shuttles to the blocking block position alongthe gap between the filter element box and a filter element, the wind is blocked by the blocking block, so that the wind is forced to penetrate through the outer wall of the cylindrical filter element, the contact area between the wind and the filter element is improved, and the filtering effect is improved.

Description

technical field [0001] The invention belongs to the technical field of ventilation equipment, and more specifically relates to a ventilation device used in a medical room. Background technique [0002] The operating room is a place to provide surgery and rescue for patients, and it is an important technical department of the hospital. The operating room should be connected with the operating department and close to the blood bank, intensive care unit, anesthesia recovery room, etc. Do a good job in the management of the four channels of surgical incision infection, namely: the air in the operating room; the items needed for the operation; the fingers of doctors and nurses and the skin of the patient to prevent infection and ensure the success rate of the operation. [0003] For example, the application number: CN201711463782.2, the present invention discloses a ventilation device for thoracic surgery operating room, including a ventilation pipe, the top of the ventilation p...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a ventilation device used in a medical room to solve the existing problem that the filtering effect is low, and the existing device cannot ensure the maximum contact between the wind and the filter element during use. , resulting in an inconspicuous filtering effect; moreover, the cost is relatively high, and most existing devices use a motor to drive a fan for ventilation, which requires computer consumption and high manufacturing costs; finally, the existing device is used for a short period of time The filter element needs to be replaced, and the maintenance cycle is short
