Technical Field
The invention belongs to the technical field of medical rehabilitation instruments capable of being used for Alzheimer's patients or Parkinson's diseases, and particularly relates to a Patient Transfer Device (PTD) for emergency department.
Background
Metastasis in critically ill patients is of increasing interest in medical care, and many similar studies have been performed. For example, the Family members of ICU patients can be used for reference in the development of the evaluation of migration Stress by introducing the Family members migration Stress Scale (FRSS) in foreign countries and applying the FRSS in the Family members of the ICU tumor patients. Substantive interview is carried out on family members of the ICU tumor patients, the psychological feelings and demands of the family members of the ICU tumor patients after the ICU tumor patients are transferred out are known, and a theoretical basis is provided for the psychological intervention of the family members of the ICU tumor patients. By constructing a migration plan mode, the application effect of the intervention mode in the family members of the ICU tumor patients is verified, so that the occurrence of family member migration stress of the ICU tumor patients is reduced, the care capability of the family members is improved, and the survival quality of the ICU tumor patients is improved.
Due to the improvement of science and technology and medical standards, the life of people is continuously prolonged, and the survival rate of disabled people due to injury is improved, so that the society nowadays has a lot of patients who are inconvenient to move, but due to the development of science and technology, the patients who are inconvenient to move still can keep the ability of moving by themselves by proper tools, and the moving range of the patients is different from that of patients who can only be limited to a limited area such as a residence. Various appliances which are helpful for the independent activities of the mobility-impaired people are also continuously developed, particularly the most common and important wheelchair, and the mobility-impaired people can effectively expand the activity range thereof with the help of the wheelchair so as to improve the quality of life. The early wheelchair is mainly manual and needs to be pushed by other people to move, so that the mobility-handicapped people are greatly inconvenienced, otherwise the mobility-handicapped people need to be healthy and full in upper half bodies and can push the wheelchair to move by hands. For people with weak or weak upper body, the wheelchair is not a suitable choice.
With the development of technology, many electric wheelchairs appear on the market. Because the electric wheelchair or the electric scooter is provided with the transmission system driven by electric power, the electric wheelchair or the electric scooter is very favorable for the user to move about by oneself without external force, and what is more, the electric power drive is different from the drive device of petrochemical fuel to cause environmental pollution, so the electric wheelchair or the electric scooter is deeply loved by the user. Electric wheelchairs have developed wheelchairs with a plurality of functions according to different use requirements. For example, the patent document with publication number CN109223332A provides a wheelchair with dining function, which comprises side plates, plate placing grooves, support plates, folding plates, a backrest, a fixed block, a groove, a lever, a support rod and a hydraulic telescopic cylinder, wherein the front ends of the side plates symmetrically fix two support plates, the front side of the side plates is provided with the folding plates, the left and right ends of the folding plates are symmetrically provided with two support plates, the upper ends of the side plates are provided with the plate placing grooves, the front ends of the plate placing grooves are symmetrically provided with two support plates, the front side of the plate placing grooves is provided with the folding plates, the design facilitates the collection and the expansion of the folding plates, the left end of the backrest is provided with the groove, the fixed block is arranged in the groove, the left end of the fixed block is provided with the lever, the right end of the lever is provided with the hydraulic telescopic cylinder, the upper end of the hydraulic telescopic cylinder is provided with a wheel, the invention has the advantages of convenient use, convenient adjustment, good comfort and simple structure. For example, patent document CN109431702A discloses a portable liftable wheelchair which can be lifted up and down by a manual or electric wheelchair to a height of about 500 mm. The old man or disabled person user sits on the wheelchair, can squat the same underground with other people when descending to the lowest position, can stand highly unanimously with other people when ascending to the highest position, and the seat can control the rotation 90, and the user sits and can reach the purpose of sitting with other people's tie equally on the wheelchair. The wheelchair is pulled up, and can be pulled and moved like a luggage case, so that the purposes of carrying out and storing are achieved. The folding and lifting of the wheelchair can be realized by selecting an electric or manual hydraulic and manual mechanical lifting push rod, the left-right rotation of the seat and the separation of the seat and the frame can be realized by the seat bolt handle, the folding of the pedal support rod can be realized by turning the pedal support rod, and the folding of the backrest and the armrest can be realized by pulling the armrest.
Further, there is a problem that many articles cannot be stored when a user goes out using the wheelchair device, for example, to make a purchase. Therefore, the existing wheelchair devices are increasingly paying attention to the design of the load carrying capacity of the wheelchair. For example, patent document No. CN108186215A discloses a multifunctional load-bearing wheelchair, in which a folding carrier is coupled to the front lower side of a wheelchair main frame, a telescopic buffer rear wheel frame is provided on the rear lower side of the wheelchair main frame, a control device is provided on the armrest of the wheelchair main frame, and a left power wheel and a right power wheel are provided on the left and right of the wheelchair main frame, respectively; the front lower side of the wheelchair main frame is coupled with the upper folding frame and is provided with an electric push rod A, the front end of the upper folding frame is coupled with the lower folding frame, and the lower sides of the upper folding frame and the lower folding frame are respectively provided with a rear connecting strip and a front connecting strip which are connected with an electric push rod B arranged in the upper folding frame; the front lower end of the downward folding frame is provided with a front universal wheel, and the front end of the downward folding frame is connected with a foot rest in a shaft way; the rear lower side of the wheelchair main frame is connected with a buffer frame in a shaft mode, an expansion bracket is movably arranged in the buffer frame, and the rear lower end of the expansion bracket is provided with a rear universal wheel; the invention has the advantages that: can be automatically folded, stretched and adjusted, can carry people, goods and shopping, and has the advantages of fast adaptation of the control device, more convenient operation, safer, more stable and more comfortable running. However, the wheelchair has at least the following problems: 1. the width dimension of the wheelchair can not be adjusted, so that the center axial plane of the wheelchair is fixed, and after a user turns over, the center of gravity of the user can deviate, and further can deviate from the center axial plane of the wheelchair, so that the side turning of the wheelchair is easily caused. 2. Due to the risk of side turning, the wheelchair can be used for turning over when the wheelchair is still in a limited use environment, and the wheelchair cannot be adjusted in width, so that emergency transfer is needed for emergency treatment when the user has an emergency, and the wheelchair cannot pass through or needs to be stopped to allow the user to pass through after turning over when the user encounters narrow areas such as narrow doors, narrow elevators and the like, thereby delaying time and missing optimal treatment time. 3. In the driving process, the folding load-carrying frame is arranged at the front part of the wheelchair, so that when the folding load-carrying frame is in an unfolding state, the bumpiness of a user can be increased. Meanwhile, in the process of transferring the patient needing first aid, the existing wheelchair cannot effectively reduce the jolt degree of the patient, and further the problem of deterioration of the condition of the patient possibly occurs. Accordingly, the present invention is directed to a patient transfer device that at least reduces the user's bumpy feel.
Furthermore, on the one hand, due to the differences in understanding to the person skilled in the art; on the other hand, since the inventor has studied a lot of documents and patents when making the present invention, but the space is not limited to the details and contents listed in the above, however, the present invention is by no means free of the features of the prior art, but the present invention has been provided with all the features of the prior art, and the applicant reserves the right to increase the related prior art in the background.
