Air interchanger for use in medical room

Abstract

The invention provides an air interchanger used in a medical room, relates to the field of medical ventilation instruments, and solves the problem that air cannot be in contact with a filter element to the maximum extent. Furthermore, most existing devices drive fans to ventilate through motors, computers need to be consumed for ventilation, the manufacturing cost is high, and maintenance period is short. The air interchanger used in the medical room comprises a box body. The box body of the air interchanger used in the medical room is rotatably connected with a rotating shaft, and the rotating shaft is fixedly connected with a cylindrical fan. Due to the arrangement of a stop block, when air enters a filter element box of the cylindrical structure and shuttles back and forth to the stop block along the gap between the filter element box and the filter element, the air can be stopped by the stop block, so that the air can be forced to permeate through the outer wall of the cylindricalfilter element, the contact area between the air and the filter element is increased, 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...

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
