Problems solved by technology

[0004] Although the foldable stretcher has the characteristics of lightness, portability and ease of use, the lower ends of the four lower poles at the bottom of the foldable stretcher are equipped with four universal wheels. When this stretcher is used in areas where natural disasters occur , due to the rough roads in areas where natural disasters occur, the patient suffers from bumps, the center of gravity is unstable, and it is easy to fall over, and the four wheels bear the weight of the entire patient, which makes the wheels wear more seriously, so the service life is not long

Embodiment 1

[0030] A GPS positioning module applied to a multi-wheel stretcher bed, which includes two parts: a stretcher bed and a GPS positioning module. The stretcher bed is mainly used to transport patients in areas where natural disasters occur. The multi-wheel stretcher bed includes crossbars 24 on both sides, and the crossbars 24 on both sides are connected by a stretcher cloth 17. The two ends of the stretcher cloth 17 are respectively sleeved on the crossbars 24 on both sides to form a simple stretcher. bed. Two upper bed legs 20 are arranged below the cross bar 24 on each side, and the two upper bed legs 20 are correspondingly arranged at two ends of the cross bar 24 . Each upper bed leg 20 is provided with a locking mechanism 23, the locking mechanism 23 is made up of a handle and a fastening screw fixedly connected on the handle, one end of the fastening screw passes through the hole on the top of the upper bed leg 20 and tightens the part. Fixing screw stretches in the uppe...

Embodiment 2

[0033] On the basis of Embodiment 1, a vertical plate 12 is also provided between the cross bar 24 and the upper bed leg 20, the upper end of the vertical plate 12 is fixedly connected with the cross bar 24, and the lower end of the vertical plate 12 is connected to the upper bed leg through the fifth hinge shaft 13. 20 hinged connections.

[0034] Because the lower end of the vertical plate 12 is hingedly connected with the upper bed leg 20, the lower end of the vertical plate 12 can rotate around the fifth hinge shaft 13 to realize the folding of the bed leg and reduce the footprint of the stretcher bed.

Embodiment 3

[0036] On the basis of Embodiment 1 or Embodiment 2, the cross bar 24 is connected with a bolt 10 by a rope, and the lower bed leg 21 below the cross bar is provided with a bolt hole 14. The size and position of the bolt 10 and the bolt hole 14 are similar adaptation. After the lower bed leg 21 rotates 90° around the vertical plate 12, the latch hole 14 on the lower bed leg 21 is just at the position of the latch 10, so that the latch 10 can be inserted into the corresponding latch hole 14 more conveniently.

[0037] The cross bar is connected with a bolt 10 by a rope, and the lower bed leg 21 is provided with a bolt hole 14 that is compatible with the bolt 10, so that after the folding stretcher bed is folded, the bolt 10 is inserted into the corresponding bolt hole 14, so that the lower bed The legs 21 are unlikely to shake from side to side, affecting use, and can effectively reduce the floor space of the stretcher bed.

Abstract

The invention discloses a GPS (Global Positioning System) positioning module applied to a multiwheel stretcher, belonging to a stretcher in the technical field of medical instruments and aiming at providing a multiwheel stretcher which has longer service life and is used for natural disasters, and has the advantages of reducing the wear degree of wheels and improving the stability of the stretcher except for transportation of the wounded. According to the technical scheme, the GPS positioning module comprises a stretcher and a GPS module, wherein the stretcher comprises cross bars on two sides, the cross bars on the two sides are connected through stretcher cloth, upper stretcher legs are connected below the cross bars and provided with a locking mechanism, the upper stretcher legs are sheathed with lower stretcher legs which can move along the length direction of the upper stretcher legs and can be locked and fixed by the locking mechanism, and two universal casters are correspondingly arranged on the two sides of the lower stretcher legs; the GPS module consists of a power supply module, and a GPS module and a communication module which are connected with the power supply module.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a stretcher bed, in particular to a GPS positioning module applied to a multi-wheel stretcher bed. Background technique [0002] A stretcher bed is a rescue tool for transporting the injured. It is mainly supported by two support bars with a canvas bed, and the two ends of the support bars are connected with handles and pulleys. However, along with the wide application of the stretcher bed, in order to adapt to various application environments, the stretcher bed has gradually evolved from the original simple stretcher bed. However, the stretchers widely used at present are generally long standard stretchers, which are suitable for carrying and using in hospitals and open and spacious places. In addition, they are also widely used in natural disaster areas in my country. However, most of the natural disasters that have occurred in our country in recent years have occurre...
