Description

Shovel type stretcher vehicle

Technical Field

The utility model relates to a stretcher especially relates to a shovel formula stretcher.

Background

At present, medical stretcher workers in hospitals commonly have a person-missing condition, people (family members and neighbors) except the medical workers are usually required to assist in lifting the stretcher, old community facilities are old, and corridor stenosis is not suitable for passing. The traditional stretcher has a single structure, the conveying principle (direct conveying) and the lifting and transporting mode (multi-person lifting and transporting) are original, the physical strength and the energy of a large number of medical staff are consumed, and the precious rescue time is wasted. How to safely and quickly transfer the sudden high-risk patients and the old patients with weak constitution from upstairs to downstairs ambulances is a critical problem facing and urgently waiting to be solved at the present stage.

However, the size, operation mode and weight of the traditional stretcher are limited by the operation intensity of people, which causes the problems of slow transportation speed and unsmooth transportation, and the transportation rescue efficiency is obviously low in emergency. Most of the stretcher designs on the market still focus on the optimization and improvement of the stretcher, and the functions of medical staff and patients are difficult to achieve. In the using process of a stretcher and medical staff, proper design aiming at different conditions is lacked, so that the complaint degree of users on good experience, specialty and technology is more and more intense.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model discloses a stretcher 1 and stretcher frame 5, the left and right sides of stretcher frame 5 one end respectively is equipped with a buckle 8, and stretcher 1 pushes stretcher in through the buckle 8 parallel of both sides in, and buckle 8 is closed after stretcher 1 pushes, prevents its slip or drop with stretcher 1 card in stretcher. The operation panel 4 is installed at the end of the stretcher frame 5, and the person lifting the stretcher can control the working state of the stretcher to be the upright moving state as shown in fig. 5, or the storage rotating state when getting in and out of the ambulance as shown in fig. 4, that is, the bearing bar 6 of the stretcher rotates upward and downward with the motor 3 as the center point. Consider the attention to the patient, operating panel 4 accessible bluetooth transmission connection vital sign monitor is fed back to the patient condition anytime and anywhere, in time salvages. Two sides of the operation panel 4 are respectively provided with a handle, which is convenient for a stretcher person to push the stretcher vehicle to move. The central positions of the left side and the right side of the stretcher outer frame 5 are respectively provided with a motor 3, and the front-back balance of the stretcher 1 is kept by the motors 3 and the gravity sensors carried by the motors. The bottom of the motor 3 is connected with a bearing rod 6 to ensure that the stretcher always keeps level with the ground in the use state. The bottom ends of the two bearing rods 6 are respectively connected with the tires 7 through rotating shafts 11, and spring dampers 14 are attached to the joints of the tires 7 and the bearing rods 6.

As shown in fig. 2 and 3, the tire 7 comprises a plurality of hubs 13, a shock-absorbing split tire 10 is arranged between every two hubs 13, and the top end of each hub 13 is connected with a small wheel 9 respectively to ensure the normal running of the stretcher on the flat ground. Each hub 13 is also fixed with a spring 15, and two tentacles of the spring 15 respectively abut against two ends of the corresponding shock-absorbing split tire 10. The inner side of each shock absorption segmentation tire 10 is provided with a blocking plate 12, the blocking plate 12 is located between two antennae of a spring 15, and when the maximum compression amount is reached, the blocking plate 12 abuts against a hub 13 to prevent the spring 15 from rebounding due to the overlarge compression angle. When the shock absorption split tires 10 between the hubs 13 contact stairs, the single shock absorption split tires 10 are compressed into the tires 7 through the springs 15, the compression is gradually increased along with the increase of the pressure, after the tires 7 roll integrally to generate displacement, the pressure of the single shock absorption split tires 10 is gradually reduced, and the single shock absorption split tires rebound to the initial positions along with the springs 15, so that the shock absorption effect of the tires 7 on the upstairs and downstairs is achieved.

As shown in fig. 1, the overall width of the stretcher is about 726mm, and the diameter of the stretcher tire 7 is about 750mm, which is in line with the average stair height in transportation and ergonomic. The stretcher outer frame 5 is made of PPO engineering plastics, and the stretcher 1 is made of aluminum alloy. The stretcher 1 is also provided with a binding band 2, an illuminating lamp strip and a warning lamp strip which are lightened in a dark environment, so that unnecessary injuries are reduced. The multifunctional intelligent shock absorption device has the functions of stably absorbing shock, going upstairs and downstairs, reducing manpower use, detecting vital signs, decomposing and quickly shoveling into a patient, automatically balancing front and back height and illuminating at night. The stretcher outer frame 5 is also internally provided with a detachable storage battery, so that the stretcher outer frame is convenient to charge and replace in an ambulance.

The utility model discloses a tire 10 is cut apart in the shock attenuation and 14 two-layer shock attenuation methods of spring damping reach the function of going upstairs and downstairs. The first layer of shock absorption is as follows: the large hub rotates in the process of going up and down stairs, so that the shock absorption segmentation tire 10 contacts the stairs to compress the spring 15 in the stairs, and the spring 15 compresses and rebounds according to the pressure to keep the horizontal inclined downward movement of the stretcher. The second layer of shock attenuation is: the progressive spring on the outer side of the spring damper 14 connected with the central rotating point of the large hub and the double-cylinder shock absorber on the inner side further weaken the impact and the vibration on the stretcher, thereby achieving the double-layer efficient shock absorption effect.

The utility model discloses an use flow does: after the medical staff carries the stretcher vehicle and gets into the patient's family, at first open the bayonet socket 8 of stretcher frame 5, take out stretcher 1, shovel the patient into shovel stretcher, tie bandage 2. After the stretcher 1 is adjusted to the shape shown in fig. 4 by the operation panel 4, the shovel stretcher is slid in through the stretcher outer frame 5, and the buckle 8 is closed. The stretcher shape is restored by operating the operation panel 4, and the patient can be carried to the stretcher. The organism adopts the self-balancing system and then reaches the effect of steady transportation. When the user goes down stairs, the stairs are in contact with the shock absorption segmentation tires 10, so that the shock absorption segmentation tires 10 rotate, the effect of stable shock absorption is achieved through the springs 15, and the effect of limitation is achieved through the stop plates 12. When the flat ground runs, the small wheel 9 contacted with the ground rotates, thereby achieving the pushing effect.
