Description
Technical field
The present invention relates to the control systems of medical conversion equipment, are specially a kind of air for negative pressure isolation transfer device
Control system.
Background technology
When the patient of transhipment is with that can pass through airborne disease, medical staff usually requires sufferer being put into negative
It is shifted in the equipment of pressure.Because when negative pressure equipment shifts, even equipment has the gap, the fresh air of only outside can flow
Enter, without having the air to carry the germs of a disease outflow.Air so outside medical environment would not be contaminated, so as to reduce medical matters
The infected chance of personnel.
Present applicant has developed a kind of negative pressure isolation transfer device, including stent, coated stent and the isolation film closed
And ventilating mechanism, isolation film is interior to form isolation cabin, and isolation cabin is equipped with air inlet and gas outlet, and ventilating mechanism includes power supply, bears
Press pump and filtration members, power electric connection negative pressure pump, the gas outlet of the air inlet connection isolation cabin of negative pressure pump, the gas outlet of negative pressure pump
The air inlet of filtration members is connected, the air inlet of isolation cabin is communicated with filter device, and opening for patient's entrance is further opened on isolation film
Mouthful, opening is equipped with closing cap, and isolation film uses flexible material, and stent is telescoping shoring column, and confession is additionally provided on the outer wall of isolation film
Woven hose and catheter by bar shaped stitch, bar shaped has seamed pressure-sealing zipper, and it is close to be externally provided with that isolation film is located at pressure-sealing zipper
Mounting.Patient in the isolation cabin of transfer device, isolation cabin there are the problem of be, due to being also required in the way of transhipment as patient
It cures, therefore pressure-sealing zipper is provided on the isolation film in isolation cabin, when actual treatment needs to pull open pressure-sealing zipper, will be defeated
Liquid pipe or catheter are externally introduced in isolation cabin.Pull open the possibility that pressure-sealing zipper increases the air leakage that carries the germs of a disease.
The content of the invention
The present invention provides one kind to solve the problems, such as to cause air in isolation cabin that may reveal because of setting pressure-sealing zipper
The control system of gas leakage possibility in isolation cabin can be reduced.
The present invention provides base case：It is close including being arranged at for the air control system for air of negative pressure isolation transfer device
Seal assembly and controller on mounting, seal assembly include two chain halfs being oppositely arranged, chain half include flexible band,
Several magnetic patch, several ferromagnetism blocks and pressure sensor, band are equipped with installation groove and installation protrusion, installation groove and peace
It fills bulge clearance to set, ferromagnetism block is fixed in installation groove, and magnetic patch is fixed in installation protrusion, and pressure sensor is fixed on
The working face of magnetic patch, the signal input part of the output terminal connection controller of pressure sensor signal, the output end signal of controller
Negative pressure pump is connected, controller receives the pressure value of all pressure sensor transmission, and all pressure values are added to obtain pressure
And value, the controller are used for the output power that the control in pressure and value increase reduces negative pressure pump.
Seal assembly is made of two pieces of chain halfs, flexible band as connection structure, connect rigid magnetic patch with it is ferromagnetic
Property block, chain half is provided with magnetic patch and ferromagnetism block, two pieces of chain halfs enable voluntarily to be closed, and has better seal effect, is provided with
Installation groove makes sealing more be bonded with installation protrusion, and after mutually chimeric, adjacent magnetic patch and ferromagnetism block attract each other enhancing
Transverse sealing.When there is woven hose to be placed between two pieces of chain halfs, woven hose can make between opposite magnetic patch and ferromagnetism block
Possesses certain gap, the suction of the bigger ferromagnetism block in gap and magnetic patch is smaller, and it is smaller that pressure sensor receives pressure, therefore
The pressure and value that controller receives are bigger, illustrate that the gap of two and half interchains is just smaller, that negative pressure pump is transported with relatively low power
Row also can guarantee that the gas in isolation cabin does not leak, and the opposite pressure received when controller and value are smaller, just explanation two and half
The gap of interchain is bigger, that negative pressure pump just must just can guarantee that the gas in isolation cabin does not leak with high-power operation.
Compared with prior art, it is the advantages of this programme：
1. the chain half of seal assembly can be voluntarily close and be closed bar shaped seam, the sealing effect for making isolation cabin is more preferable.
2. controller according to the size being open between chain half, can control the operation power of negative pressure pump, make negative pressure pump to close
The Power operation of reason reduces the energy consumption of negative pressure pump, extends the usage time of equipment.
Scheme two：For the preferred of basic scheme, oxygen supply mechanism is further included, mechanism is supported to include oxygen cylinder, conduit and oxygen
Gas mask, conduit connection oxygen cylinder and oxygen mask, conduit is interior to be equipped with air valve.Advantageous effect：The usual lung function of patient is not strong, if
It puts oxygen supply mechanism and provides oxygen for sufferer, avoid causing patient that can not breathe enough oxygen due to air pressure becomes smaller.
Scheme three：For the preferred of scheme two, air valve signal connection controller, controller controls when increasing for pressure and value
Reduce the opening area of air valve.Advantageous effect：When negative pressure pump high power operation, internal gas flow flow velocity is very fast, therefore oxygen
The speed of spilling is also very fast, and air valve, which opens smaller angle, can also have enough oxygen to overflow the sick Man's Demands of satisfaction.
Scheme four：For the preferred of scheme three, ferromagnetism block is steel material.Advantageous effect：Steel material has enough intensity,
Service life is long, not perishable, can keep clean for a long time.
Scheme five：For the preferred of basic scheme, ferromagnetism block is cased with fluid sealant outside.Advantageous effect：Ferromagnetism block hardness is too
It is high, it is not easy to which that gluing, sealing inevitably has the gap in fitting between magnetic patch, is cased with fluid sealant outside and can overcome the disadvantages that gap, enhancing sealing
Property.
Scheme six：For the preferred of scheme five, magnetic patch surface is covered with sealant.Advantageous effect：Magnetic patch and ferromagnetism block phase
Mutually attract, sealant and fluid sealant gluing, sealing, seal assembly is made both to have possessed and is voluntarily bonded characteristic but also with good leakproofness.
