Description

Cervical traction type stretcher
The present invention be Application No. 201710549892.4, the applying date be on July 7th, 2017, it is entitled that " cervical vertebra is led Draw formula stretcher " patent divisional application.
Technical field
The present invention relates to stretcher field, more particularly to a kind of cervical traction type stretcher.
Background technology
Common stretcher has following several：
1st, scoop stretcher, scoop stretcher are made up of left and right two panels aluminium alloy plate.When carrying the wounded, first the wounded are placed on Horizontal position, fixed neck, the left and right two panels of stretcher is then inserted into back from wounded side respectively, carried again after fastening.
2nd, negative pressure air-filled cushion fixes stretcher, and it is to carry multiple fracture and backbone damage to fix stretcher using negative pressure air-filled cushion The best tool of the wounded.Inflatable packer can suitably fix the whole body of the wounded.It will first be paved during use after pad gas, by the wounded It is placed in pad, extracts air in bag out, air cushion is solidifiable, while the wounded are just fixed firmly in wherein, and can be in way is carried Remain stable.
3rd, basket stretcher, also cry " ship type stretcher " (Stoke Basket), it is common for two types on the market：Aluminium alloy Type；Synthetic resin type；His moulding is similar to its title, as one " canoe ".When carrying trapped personnel, trapped personnel is placed in load In frame, stretcher the positive bandlet of surrounding " projection " edge mate by trapped personnel " closing " inside stretcher.So will not be because The displacement (such as overturn, rock) of stretcher and make trapped personnel depart from stretcher.In the behind of security, there is also some hidden danger.Such as Trapped personnel is excessively fat, and is bundled in its positive bandlet tension the operating time is long in addition, then easily trigger trapped personnel it is uncomfortable in chest, Asphyxia.North America fire-fighting circle will be referred to as " iron coffin " (early due to the mishandling situation for causing trapped personnel to die from basket stretcher Phase basket stretcher is mostly aluminium alloy).
4th, rolling stretcher, " multifunctional stretcher " (Sked) is also, it is upper similar in use to basket stretcher, but weight is lighter (8 to 12 kilograms) and it can crispatura and carried in roller or knapsack.Its raw material is extraordinary synthetic resin, there is a corrosion resistance, one As be crocus.Rolling stretcher on continental market is mostly the like product of the imitative Japan and Korea S. such as Jiangsu, Zhejiang.In North America fire-fighting Boundary, the behavior for causing trapped personnel to be died inside rolling stretcher by improper due to emergency crew operations are referred to as " cered " (early stage rolling stretcher is mostly that high intensity canvas is made).
However, corresponding walk for the stretcher of mountain area or steep hillslope band, because the climbing of stretcher in itself is highly deposited In certain threshold value, if front is gone up a slope, climbing height threshold of the height beyond stretcher, stretcher can not go up a slope.It is existing Corresponding mechanism is still lacked to the upward slope identification in front of stretcher and height detection in technology.
The content of the invention
In order to solve the above problems, the invention provides a kind of cervical traction type stretcher, between including vertical direction etc. The upward slope of multiple infrared ray sensors away from setting judges that the front gradient is identified equipment, using targetedly image procossing Mechanism completes the height detection gone up a slope to front, and sends climbing failure signal in time.

In the cervical traction type stretcher：The time division duplex communication interface will by two-way time division duplex communication link The current GPS location of climbing failure signal and stretcher is wirelessly transmitted at the hand-held mobile terminal of Relatives of Patients Hospitalized.
In the cervical traction type stretcher, in addition to：
Bluetooth communication interface, it is arranged in the side rod of left side, for the hand-held shifting by two-way bluetooth communications link and patient Dynamic terminal connection, receives the various control instructions that patient is sent by its hand-held mobile terminal to stretcher.
In the cervical traction type stretcher, in addition to：
Power supply unit, for providing supply of electric power for each electrical equipment of stretcher；Wireless charging device, for powering During electric power of equipment deficiency, carry out carrying out wireless charging to power supply unit by wireless charging stake nearest nearby.
In addition, time division duplex is a kind of duplex mode of communication system, be used to separate in mobile communication system receive and Transmit channel.Positive third generation development, China have submitted 3G (Third Generation) Moblie standard grass in June, 1997 to mobile communication at present Case (TD-SCDMA), the characteristic such as its tdd mode and smart antenna new technology are greatly prized by and into three main candidate standards One of.Fdd mode rules all the land in the first generation and second generation mobile communication system, and tdd mode does not draw attention.But due to The needs of new business and the development of new technology, and many advantages of tdd mode, tdd mode will be increasingly subject to pay attention to.
The operation principle of time division duplex is as follows：TDD is a kind of duplex mode of communication system, is used in mobile communication system Received and transmission channel (or uplink downlink) in separation.Received in the GSM of tdd mode and transmission is same Frequency channels are the different time-gap of carrier wave, are received and transmission channel with the time is ensured to separate；And the mobile communication system of fdd mode The reception and transmission of system are on two symmetrical frequency channels of separation, are received and transmission channel with frequency range is ensured to separate.
It is different using the GSM feature and communication benefit of different dual-modes.The movement of tdd mode is led to The same frequency of up-downgoing channel in letter system, thus the reciprocity with up-downgoing channel, this leads to the movement of tdd mode Letter system brings many advantages.
In tdd mode, in up-link and downlink the transmission of information can be carried out in same carrier frequency, i.e., The transmission of information is to be realized on same carrier wave by the time-division in the transmission of information and downlink in up-link.
Using the cervical traction type stretcher of the present invention, effective cervical traction type can not be carried out for stretcher in the prior art And the technical problem of mountain area climbing early warning, cervical traction mechanism is completed by introducing multiple mechanical components, it is multiple by introducing Image processing equipment completes front upward slope height detection, and can pass through channel radio when front is gone up a slope and highly exceeds climbing ability Letter mode is alarmed in time.
