Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a portable nursing stretcher for helicopter evacuation. Background Art
[0002] With the improvement of our military's equipment level and logistical support, dedicated medical rescue aircraft have become an important force in modern medical support. They have long evacuation distances, strong rescue capabilities, and good comfort for the wounded and sick, which can meet the needs of rapid air transport and evacuation of critically ill patients. Dedicated medical rescue aircraft can usually be divided into unit modules such as intensive care, basic treatment, auxiliary diagnosis, and medical support according to their functions. Among them, the intensive care module consists of a bed, medical equipment, and a dedicated rescue stretcher, which is mainly used for air transport and emergency treatment of critically ill patients on the way. The dedicated rescue stretcher is mainly used for the transfer and supine fixation of the wounded and sick, ensuring the safety and comfort of the wounded and sick, and facilitating the medical staff to carry out rescue work. It is an important part of the intensive care module.
[0003] Since the helicopter used for rescue and evacuation is small in size and the internal space utilization rate is not high, the existing rescue stretcher adopts a folding method, but the folded stretcher is large in size and cannot be used for evacuation helicopters. In addition, during the transportation of the evacuation helicopter, the fuselage will tilt or bump, and the randomly placed medicines and consumables will slide or be lost due to the tilt of the fuselage during treatment. Therefore, those skilled in the art provide a portable nursing stretcher for helicopter evacuation to solve the problems raised in the above background technology. Utility Model Content

In addition, during the transportation of the transport helicopter, the fuselage may tilt or bump, and the medicines and consumables placed randomly may slide or be lost due to the tilt of the fuselage during treatment.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable nursing stretcher for helicopter evacuation, comprising a first section bracket and a medicine and consumables storage box, a middle section bracket is arranged on one side of the first section bracket, a tail section bracket is arranged on the other side of the middle section bracket, the middle section bracket is arranged between the first section bracket and the tail section bracket, and multiple groups of middle section brackets are arranged, and the lengths of adjacent middle section brackets gradually increase, and the first section bracket, multiple groups of middle section brackets and the tail section bracket are connected in sequence to form a nursing stretcher, and the first section bracket is arranged between the first section bracket and the tail section bracket. Limiting slide grooves are provided at the bottom of both sides, first magnetic sheets are installed on the upper ends of both sides of the middle bracket, second magnetic sheets are installed on the lower ends of both sides of the tail bracket, a connecting shaft is installed at the inner end of the first bracket adjacent to the middle bracket, a card slot is provided above the connecting shaft, a connecting ear is installed at the inner end of the tail bracket adjacent to the middle bracket, a card block is provided above the connecting ear, a pull rod is installed on the front side of the medicine and consumables storage box, a card strip is installed on one side of the medicine and consumables storage box, and a bottom plate is installed on the rear side of the medicine and consumables storage box.
[0007] Preferably, the connecting ear is rotatably connected to the connecting shaft. Since the first section bracket, multiple groups of middle section brackets and the tail section bracket are rotatably connected to the connecting ear through the connecting shaft, the nursing stretcher can be rolled up, reducing the volume occupied.
[0008] Preferably, the tail section bracket is magnetically connected to the first magnetic sheet on the middle section bracket through the second magnetic sheet. After the nursing stretcher is rolled up, the rolled-up nursing stretcher can be stabilized by the magnetic attraction of the first magnetic sheet and the second magnetic sheet to avoid looseness.
[0009] Preferably, the card block is damped and plugged into the card slot. When the nursing stretcher composed of the first section bracket, multiple groups of middle section brackets and the tail section bracket is formed, the extrusion connection between the card block and the card slot can effectively prevent the gap between the brackets from loosening when the wounded is carried, causing pinching injuries to the wounded. The card block and the card slot are extruded and plugged in a damping manner, and can be disconnected after applying force.
[0010] Preferably, a handle is installed at one end of the first section bracket away from the middle section bracket, and a handle is also installed at one end of the tail section bracket away from the middle section bracket for lifting the nursing stretcher.
[0011] Preferably, the medicine and consumables storage box is slidably connected with the limiting slide groove through a card strip, and the bottom plate is in contact with one side of the first section bracket, so that the rolled nursing stretcher can be lifted by a pull rod, and the problem of medicines and consumables being randomly placed and lost will not occur.

After the nursing stretcher is rolled up, the rolled-up nursing stretcher can be stabilized by the magnetic attraction of the first magnetic sheet and the second magnetic sheet to avoid looseness. In addition, limiting grooves are provided at the lower part of both sides of the first section bracket. Since there is space in the middle part of the rolled-up nursing stretcher, a long strip of medicine and consumables storage box is provided. A pull rod is installed on the front side of the medicine and consumables storage box. After the side of the medicine and consumables storage box with the card strip is plugged into the limiting slide groove, the bottom plate is pressed and contacted with one side of the nursing stretcher, so that the rolled-up nursing stretcher can be lifted up by the pull rod, which is convenient to carry, and there will be no problem of medicines and consumables being placed randomly and lost.
