Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a folding stretcher device used for ambulance modification. Background Art

[0002] With the increase of sudden illnesses nowadays, ambulances are an important means of transportation to protect these lives. Stretchers are needed to bring these patients to the ambulance. Stretchers can help patients move stably to the vehicle for emergency treatment in the vehicle. Stretchers are essential for patients who are racing against time. Existing ambulance transport stretchers can be roughly divided into two categories: one is fixed type, and the other is retractable folding cart type. The fixed type has a single function, which is inconvenient to carry on and off the vehicle, increasing the workload of medical staff. The retractable folding cart type has a complex structure, a heavy body, can only slide on flat ground, and is difficult to carry up and down stairs.

[0003] In response to the above problems, a multi-terrain ambulance transport stretcher is disclosed in Chinese patent announcement with announcement number CN213552986U, and its technical highlights are: it includes a stretcher body, a cushion, a cushion lifting device and a supporting and moving device, the supporting and moving device includes a supporting frame, a folding supporting frame, an S-shaped supporting arm, triangular wheels, universal wheels, etc. The supporting and moving device can be folded and recovered and does not take up space in the ambulance. The S-shaped supporting arm, triangular wheels and universal wheels and a reset motor can realize the process of climbing stairs easily.

[0004] In actual operation, it was found that the above scheme still has at least the following defects: the device is inconvenient when transporting patients into the vehicle. After the first support frame and the second support frame are recovered and folded together on the bottom surface of the stretcher table, only the upper wheels and medical staff entering the ambulance are required to support the weight of the stretcher and the patient, which is time-consuming and labor-intensive, and also affects the comfort of the patient. For this reason, we propose a folding stretcher device for ambulance modification to solve the above problems. Utility Model Content

The two reinforcing cross bars 10 are respectively It is fixedly installed on the two U-shaped frames 8, the two first hinge seats 11 are respectively fixedly installed on the left sides of the two reinforcing cross bars 10, the two first hinge blocks 12 are respectively rotatably installed on the two first hinge seats 11, and the two electric push rods 13 are respectively fixedly installed on the two first hinge blocks 12. By utilizing the two electric push rods 13, the two U-shaped frames 8 can be simultaneously controlled to be folded, stored and unfolded, the two second hinge seats 14 are both fixedly installed on the bottom of the stretcher board 1, and the two second hinge blocks 15 are respectively rotatably installed on the two second hinge seats 14, and the two electric push rods 13 are respectively fixedly connected to the corresponding second hinge blocks 15 at one end away from the corresponding first hinge blocks 12.

[0027] In this embodiment, a connecting seat 20 is fixedly installed on the top right side of the above-mentioned stretcher board 1, a connecting shaft 21 is rotatably installed on the connecting seat 20, a pedal 22 is fixedly installed on the connecting shaft 21, and two symmetrically distributed springs 23 are fixedly installed on the pedal 22. The ends of the two springs 23 away from the pedal 22 are fixedly connected to the stretcher board 1. Through the above-mentioned arrangement, the soles of the patient's feet can be supported to prevent the patient from sliding on the stretcher board 1 when moving on an inclined road surface.

[0028] In this embodiment, the front and rear sides of the stretcher board 1 are provided with storage grooves 29 located above the slide groove 16, and drawer boards 30 are slidably installed in the two storage grooves 29. By using the drawer boards 30, a ventilator and other equipment can be used for the patient when needed.

Two L-shaped limit plates 19 are fixedly installed at the bottom of the stretcher board 1, and the two L-shaped limit plates 19 are respectively in conflict with the corresponding U-shaped frames 8. By utilizing the two L-shaped limit plates 19, the two U-shaped frames 8 can be restricted and fixed.

[0030] Through the above structure, the folding stretcher device for ambulance modification provided by the utility model can actively control the folding legs to be folded, stored and unfolded, so as to avoid the folding legs being retracted by bumping when entering the ambulance, reduce the vibration suffered by the patient, improve the comfort of the patient, and conveniently control the stretcher board 1 to get on and off the ambulance, which saves time and effort while making the stretcher board 1 slide more stably and smoothly. In specific use, when the ambulance arrives at the scene, since there is no weight on the stretcher board 1, the medical staff can directly hold the push rod on the left side. 2, pull the stretcher board 1 out of the vehicle, so that the two first upper wheels 4 on the right side still stay on the ambulance, control the two electric push rods 13 to extend, so that the two U-shaped frames 8 are unfolded, and the two triangular wheels 9 touch the ground. At this time, the stretcher board 1 can be directly controlled to move. When there is a patient on the stretcher board 1, the patient is stabilized by the safety belt to prevent the patient from falling from the stretcher board 1 during transportation. At the same time, the pedal 22 can be opened to provide a certain support for the patient's feet. When the stretcher board 1 and the patient are sent to the vehicle, first The two first upper wheels 4 on the right side are first placed on the ambulance, and the electric push rod 13 on the right side is controlled to retract. After the folding legs on the right side are folded, the stretcher board 1 is pushed to move to the right. Subsequently, the slide plate 17 is controlled to slide to the right so that the two second upper wheels 5 are placed on the ambulance, so as to achieve the purpose of supporting the stretcher board 1 with the two first upper wheels 4 and the two second upper wheels 5. Then, the electric push rod 13 on the left side is controlled to retract, and the folding legs on the left side are folded. At this time, the two second upper wheels 5 can be controlled by hand without moving and pushed to the right. The stretcher board 1 can be smoothly pulled into the ambulance when the stretcher board 1 is folded and retracted, so that the medical staff can avoid lifting the stretcher board 1 laboriously and then pushing it into the ambulance after folding and retracting. This saves time and effort while improving the stability of the movement of the stretcher board 1. According to actual needs, the drawer board 30 can be opened and medical equipment such as a ventilator can be placed on the drawer board 30 to stabilize the patient's condition. The connecting rod 25 can also be erected as needed to give the patient an infusion. The practicality is greatly enhanced, and the comfort of the patient during transportation is improved.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
