Embodiment 1

[0026] Embodiment 1 is basically as Figure 4 As shown, a sealing assembly is provided on the sealing plate, and the sealing assembly includes two half-chains 610 arranged oppositely. The half-chain 610 includes a controller for controlling the operating power of the negative pressure pump, and the half-chain 610 includes a PE material sealing belt 611 and 8 magnetic blocks. 612, 8 ferromagnetic blocks 613 and 8 semiconductor pressure sensors 614, the sealing tape 611 is provided with a mounting groove 6111 that cooperates with the ferromagnetic block 613 and a mounting protrusion 6112 that cooperates with the magnetic block 612, and the mounting groove 6111 and the mounting protrusion 6112 are arranged at intervals, the ferromagnetic block 613 is fixed in the installation groove 6111, the magnetic block 612 is fixed on the installation protrusion 6112, the pressure sensor 614 is bonded to the working surface of the magnetic block 612, and the output terminal of the pressure se...

Embodiment 2

[0028] Example 2, the difference between Example 2 and Example 1 is that the isolation film is not provided with an opening and a closing cover, and the isolation film is provided with an entry zipper on the side, and a shielding sheet is bonded outside the entry zipper. After the zipper is opened, the patient is transferred to the isolation cabin.

Abstract

The invention relates to a control system for a medical transfer equipment, in particular to an air control system used for a negative-pressure isolation transfer device. The system includes a sealingcomponent and a controller which are arranged on a sealing piece, the sealing component includes two half chains arranged oppositely, a magnetic block is fixed on an installation bulge, pressure sensors are fixed on the working face of the magnetic block, and the signal output ends of the pressure sensors are connected with the signal input end of the controller, the output end of the controlleris in signal connection with a negative-pressure pump, the controller receives pressure values sent by all the pressure sensors, all the pressure values are added to obtain the sum of the pressure values, and the controller is used for controlling the reduction of the output power of the negative-pressure pump when the sum of the pressure values is increased. In order to solve the problem that airin an isolation bin is likely to leak due to the arrangement of a sealing zipper, the control system for reducing the possibility of leakage of air in the isolation bin is provided.

Description

technical field [0001] The invention relates to a control system for medical conversion equipment, in particular to an air control system for a negative pressure isolation transfer device. Background technique [0002] When transferring a patient with an airborne disease, medical staff usually need to transfer the patient into a negative pressure device. Because when the negative pressure equipment is transferred, even if there are gaps in the equipment, only fresh air from the outside can flow in, and no air with germs will flow out. In this way, the air outside the medical environment will not be polluted, thereby reducing the chance of medical staff being infected. [0003] Now the applicant has developed a negative pressure isolation transfer device, which includes a bracket, an isolation membrane wrapped around the bracket and closed, and a ventilation mechanism. An isolation chamber is formed inside the isolation membrane. The isolation chamber is provided with an air...
