A new type of foldable emergency medical stretcher

Abstract

The invention discloses a new type of foldable stretcher for emergency internal medicine, which includes a fixed transport assembly, a self-balancing magnetorheological rapid assembly stretcher, a magnetorheological rescue support mechanism, a rapid support clamping mechanism, a battery and an electromagnet. The balanced magnetorheological rapid assembly stretcher is hingedly arranged at the lower end of the fixed handling assembly, the magnetorheological rescue support mechanism is arranged on the self-balancing magnetorheological rapid assembly stretcher, the battery and the electromagnet are arranged on the fixed handling assembly, The storage battery is electrically connected to the electromagnet, and the quick support clamping mechanism is arranged on the bottom wall of the self-balancing magnetorheological quick assembly stretcher. The invention belongs to the technical field of medical devices, and specifically provides a stretcher that can be dynamically self-balanced and adjusted according to the force applied by the stretcher operator, so as to ensure that the stretcher is always kept in a horizontal state, realize rapid assembly and disassembly through magnetorheological fluid, and firmly support the patient without oppression. , quickly assembled to form a rescue table, a new type of foldable emergency internal medicine stretcher that is convenient for stretcher movement.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a novel foldable stretcher for emergency internal medicine. Background technique [0002] In the emergency clinic, the stretcher, as an auxiliary device that must be used, has assumed an irreplaceable role. There are two types of existing stretchers: fixed type and foldable type. The fixed type has a simple structure, and all parts are fixedly connected, and can be used at any time. However, it is bulky, takes up a lot of space, is inconvenient to carry, and has limited applicable environments, especially not suitable for emergency It is used for outpatient visits; the foldable stretcher is small in size, takes up little space and is easy to carry in the storage state. It is usually composed of retractable long poles on both sides and mesh cloth. The two long poles can be combined together to reduce the occupied space. The existing folding stretcher has given up the use ...

There are two types of existing stretchers: fixed type and foldable type. The fixed type has a simple structure, and all parts are fixedly connected, and can be used at any time. However, it is bulky, takes up a lot of space, is inconvenient to carry, and has limited applicable environments, especially not suitable for emergency It is used for outpatient visits; the foldable stretcher is small in size, takes up little space and is easy to carry in the storage state. It is usually composed of retractable long poles on both sides and mesh cloth. The two long poles can be combined together to reduce the occupied space. The existing folding stretcher has given up the use of the cross bar, that is, it is only composed of two telescopic long poles and the mesh. When the stretcher of this structure is in use, the mesh The cloth will bend downward under the action of its own weight and the weight of the patient's body, forcing the two long poles to approach each other, and the patient's body posture will be restrained under pressure, which is very unfavorable for normal diagnosis and treatment

In addition, the folding stretcher of this structure can only be used as a transfer tool for patients because of the lack of a stable plane support frame, and cannot be used as a workbench, which is very inconvenient for on-site rescue in emergency situations. When carrying, because the front and rear porters carry it for a long time without soreness, it is easy to cause the stretcher to tilt or the gripper of the stretcher to fall off. A little carelessness can easily hurt the patient, causing greater pain and injury to the patient, especially the fractured patient. When the workers carry the stretcher and the patient gets on or off the car, there is a height difference between the porters at both ends of the stretcher, which makes it difficult to ensure the balance of the stretcher, which is very inconvenient
