[0002] A stretcher is a medical device used by hospitals to rescue patients. It generally includes a stretcher frame and a stretcher bed. The stretcher frame is used to support the patient placed on the stretcher bed. Especially in urban emergency treatment, stretchers are most widely used. It can be said that every ambulance is equipped with a stretcher. Because the space in the corridor is relatively small and there are stairs, a large wheeled vehicle cannot enter or move. At this time, only a small and easy-to-carry stretcher can be used to carry the patient out, put him in the ambulance, and send him to the hospital for rescue.

[0003] The Chinese utility model patent with announcement number CN201959116U discloses a stretcher with an alarm, including a stretcher frame, a crossbar and a stretcher bed surface, a battery is installed on the stretcher frame, and the battery is electrically connected to the alarm fixed on the stretcher frame. By setting an alarm, and a sound and light alarm, an alarm sound and an alarm light can be emitted when needed, which can serve as a reminder, allowing others to make way for the stretcher to pass quickly. If others make way, there will be no congestion, and the patient will not be at risk of slipping off the stretcher, making the stretcher safer when in use. However, in the process of use, the prior art needs to manually control the opening and closing of the sound alarm, which is cumbersome to operate and reduces convenience.

[0029] like Figure 1-3 As shown, a stretcher in this embodiment includes a support frame 1 and a support mechanism 2, wherein the support mechanism 2 is arranged on the support frame 1, and the support mechanism 2 is used to support the support frame 1, and an alarm mechanism 3 is arranged on the support frame 1;

[0030] The alarm mechanism 3 includes a mounting seat 31, which is fixedly mounted on the support frame 1. An alarm 32 and a contact switch 33 are mounted on the mounting seat 31. The contact switch 33 is electrically connected to the alarm 32. The support mechanism 2 is used to push the trigger end of the contact switch 33.

[0031] The support frame 1 is provided with an armrest 11;

[0032] The support mechanism 2 includes a first support leg assembly 21 and a second support leg assembly 22, wherein the first support leg and the second support leg are distributed left and right;

[0033] The first support leg assembly 21 includes a first rotating frame 211, one end of the first rotating frame 211 is rotatably connected to the support frame 1, the other end of the first rotating frame 211 is provided with two first rollers 212, the two first rollers 212 are arranged front and back, the first rotating frame 211 is connected to the support frame 1 through a first locking member 213, and the first rotating frame 211 is provided with a first supporting wheel 214;

[0034] The second support leg assembly 22 includes a second rotating frame 221, one end of the second rotating frame 221 is rotatably connected to the support frame 1, the other end of the second rotating frame 221 is provided with two second rollers 222, the two second rollers 222 are arranged front and back, the second rotating frame 221 is connected to the support frame 1 through a second locking member 223, and a second supporting wheel 224 is provided on the second rotating frame 221;

[0035] The support frame 1 is provided with a third support wheel 13;

[0036] When the stretcher is pulled out of the ambulance 4, the support frame 1 is pulled to make the support frame 1 move to the left in the ambulance 4. At the same time, the first support wheel 214, the second support wheel 224 and the third support wheel 13 roll in the ambulance 4 to support the support frame 1. As the moving distance of the support frame 1 increases, the first leg assembly 21 moves to the outside of the ambulance 4, the first rotating frame 211 rotates downward, and the first roller 212 abuts against the ground. At the same time, the first rotating frame 211 and the support frame 1 are locked by the first locking member 213. At this time, the stretcher is in the first state. As the moving distance of the support frame 1 further increases, the second support assembly moves to the outside of the ambulance 4, the second rotating frame 221 rotates downward, and the second roller 222 abuts against the ground. At the same time, the first rotating frame 211 and the support frame 1 are locked by the second locking member 223. At this time, the stretcher is in the second state.

[0037] When the stretcher is in the second state, the second rotating frame 221 pushes the trigger end of the contact switch 33 through calculation, so that the contact switch 33 controls the alarm 32 to sound an alarm, reminding the surrounding people to make way for the rescue passage;

[0038] When the stretcher is used up, the support frame 1 is pushed into the ambulance 4 from left to right. During the movement of the support frame 1, the first rotating frame 211 and the second rotating frame 221 are blocked by the ambulance 4, so that the first rotating frame 211 and the second rotating frame 221 are both rotated in the opposite direction to achieve reset, that is, the first rotating frame 211 and the second rotating frame 221 are folded. At this time, the second rotating frame 221 is separated from the contact end of the contact switch 33, and the alarm 32 is in an open circuit state and stops emitting an alarm sound.

[0039] Of course, the alarm mechanism 3 can also be arranged at the first support leg assembly 21. When the first rotating frame 211 rotates completely and makes the first roller 212 abut against the ground, the first rotating frame 211 pushes the trigger end of the contact switch 33 through calculation, so that the contact switch 33 controls the alarm 32 to sound an alarm, reminding the surrounding personnel to make way for the rescue passage.

[0040] The alarm mechanism 3 also includes a lighting lamp 34, which is electrically connected to the contact switch 33. When the trigger end of the contact switch 33 is pushed, the contact switch 33 controls the alarm 32 to sound an alarm to remind the surrounding personnel to make way for the rescue passage. At the same time, the contact switch 33 also controls the lighting lamp 34 to light up, thereby increasing the light intensity of the rescue passage.

[0041] The lighting lamp 34 is an LED lamp;

[0042] The support frame 1 is provided with a push handle 12;

[0043] The support frame 1 is provided with a fixing strap;

[0044] In summary, during the use of the stretcher, the alarm 32 can be automatically turned on and off, thereby improving convenience.

[0045] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
