Description

Mobile aeration transfer mattress
Technical field
The invention belongs to medical instruments field, and in particular to a kind of mobile aeration transfer mattress.
Background technology
In today that medical resource is in short supply, it is necessary to largely cure when patient needs to change clothes or change bed after surgery or in disease Shield personnel participate in patient and praise transfer, and not only labor intensity is big for this work, once and each group personnel cooperation is not good, also hold Easily pain or even injury are brought to patient.Because the transfer work of patient is the recurrent medical matters work of hospital, therefore, reform Cry is also the most urgent, how efficient and convenient and safe transhipment patient, be the important step for solving medical resource reasonable distribution.
Under the conditions of currently available technology, there is a Patent No. on the market:201220553184.0, entitled " operation The patented technology of disposable mobile air cushion ", although the preliminary transshipment problem for solving patient, but still there is more lack Fall into.First, the cost of this disposable mattress is higher, if a mattress is used only once, that will cause huge resource Waste, and patient and hospital may be born due to rate, and refuse to use new equipment, so as to cause popularizing for new technology It is extremely difficult.Furthermore, the inflator pump of this transhipment mattress is only limited in a spacing dependent on indoor wired fixed power source supply Shifted from interior short distance, it is difficult to accomplish to sue and labour in the wild or long-distance transport uses in patient procedure.Another of prior art lacks Falling into is, when the body weight of patient is serious overweight, this transhipment mattress is still difficult to reach by one to two medical personnel Transport purpose.
Applicant passes through long-term R & D, have devised the present apparatus, can effectively solve the problem that above mentioned problem.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of mobile aeration transfer mattress, are capable of the transfer disease of Portable safety Suffer from, and it is time saving and energy saving;Second goal of the invention of the present invention is the present apparatus to be made to reuse, Economy type medicine cost;This hair The 3rd bright goal of the invention is can at a distance or field is transported through operation, wired company independent of indoor fixed power source Connect supply;The 4th goal of the invention of the present invention is can solve the problem that in the case that patient is overweight, still only with one to two doctors Shield personnel can complete the transfer of patient, and transfer process is easily convenient, and patient is safe all the time in controllable state is balanced Property is stronger.
The technical solution adopted for the present invention to solve the technical problems is:A kind of mobile aeration transfer mattress, its feature are provided It is to set more than one inflation on the inflation pad for including being made up of the rubber film of waterproof antiwear, the inflation pad Mouthful;In the surrounding of inflation pad, drawstring is set;At the back side of inflation pad, venthole is set;In the front of inflation pad, energy is set The disposable mattress dustcoat enough changed, described disposable mattress dustcoat are connected by connector with inflation pad.
Mobile aeration transfer mattress of the present invention, it is characterised in that described connector includes velcro, plastics and inserted Button or frenulum.
In the side of inflation pad, charging accumulator is set.
Also include transfer carriage and lanyard, thimble is set in the surrounding of inflation pad, lanyard passes through thimble by inflatable packer Body is lifted on transfer carriage;Described transfer carriage includes the support body of " C " shape, weight device and base;Lanyard connects the top of support body, And the center of circle position by controlling the length of lanyard to make inflatable packer body be located at support body;The bottom of support body is arranged on base, the bottom of at Weight device is set on seat.
Also include lift cylinder, described lift cylinder is arranged on the top of support body, the expansion link connection suspension of lift cylinder Rope, and can be by driving lanyard adjustment to inflate the upright position of pad.
