Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 1, the quick ampoule opening device for emergency department according to the present application is characterized in that: the ampoule bottle clamping device comprises a fixed disc 1 fixedly arranged on a rack, wherein a plurality of bottle holders 2 are uniformly arranged on the periphery of the fixed disc 1, the bottle holders 2 clamp an ampoule 3, the bottle holders 2 can rotate around a rotating shaft 13 arranged on the fixed disc 1, a synchronous belt pulley 15 is further arranged on the rotating shaft 13, and all the synchronous belt pulleys 15 are driven by a synchronous belt 16; the center of the fixed disc 1 is also provided with a central shaft 18 which is a multi-section rotatable shaft, one side of the upper surface of the fixed disc 1 is sequentially provided with a smooth shaft section, a belt pulley section fixedly provided with a belt pulley 9 and a thread section provided with a screw rod 7, the belt pulley 9 is wrapped with an unclosed belt 8, two ends of the belt 8 are connected with sand lines 6, and the sand lines 6 are tightened by guide wheels 5 uniformly distributed on the periphery of the fixed disc 1 and are pressed against the bottleneck of the ampoule 3; a part of the central shaft on one side below the fixed disc is fixedly connected with a part gear 17, and the part gear 17 is in meshing transmission with a pinion arranged on one of the rotating shafts 13;

the screw rod 7 is in threaded connection with a large pressing cap 10, the large pressing cap 10 is limited by a guide post 11 vertically arranged on the fixed disc 1 and translates up and down when the screw rod 7 rotates, and the large pressing cap 10 is provided with a slope and can be pressed to the top of the ampoule 3 bottle outwards when moving downwards;

when the ampoule bottle opener is used, the driving part gear 17 rotates for a certain angle, the central shaft 18 rotates along with the driving part gear, the belt pulley 9 drives the belt 8 to rotate, and meanwhile, the sand line 6 is pulled by the belt 8 to cut the bottleneck of the ampoule bottle 3; on the other hand, a part of gears 17 drives the pinion 14 to rotate, so that the bottle support 2 rotates, the relative motion with the sand line 6 is increased, finally, in the process that the central shaft 18 rotates, the large pressing cap 10 is driven by the rotation of the screw rod 7 to translate downwards under the guiding action of the guide post 11, and finally, the slope surface presses the top end of the ampoule 3, and the ampoule with the cut bottleneck is broken and opened.

The key points of the scheme are that 1, partial gear drives one bottle support to rotate through a pinion, all the bottle supports synchronously rotate through a synchronous belt system of each bottle support, and meanwhile, the rotation of a central shaft also enables a belt pulley 9 (not a synchronous belt pulley 15 on the bottle support) to rotate, so that a sand line system also starts to rotate; 2. the belt 8 is provided with a certain spring which can play a role of pre-tightening at two ends of the inelastic sand line, so that certain pressure is generated when the belt is pressed against the bottleneck of the ampoule; 3. the big pressing cap is also driven by a part of gears, and the transmission relation is set to make the slope surface contact with the ampoule bottle at last and press the cut ampoule bottle outwards in the downward moving process.

As shown in figure 5 of the drawings,

Further, 11 bottle holders 2 are provided, 12 guide wheels 5 are provided, and the bottle holders 2 and the guide wheels 5 are arranged at intervals.

In fact, the number of bottle holders in the present solution is not limited to the above embodiments, and it can be more or less numbers, but obviously, the number of guide wheels is 1 more than that of bottle holders.

Further, a handle 19 is mounted on the partial gear 17, and a return spring 20 is connected to the handle 19.

All actions can be completed only by rotating a part of gears by a certain angle, the ampoules are opened in batches by pulling the ampoules by a handle, and meanwhile, the reset spring enables the device to be operated more easily, and the labor intensity is reduced.

Furthermore, a limit structure for limiting the swing range of the handle 19 is arranged below the fixed disc 1.

If the swing range is too large, part of the gear and the pinion will be disengaged, so that a limit structure as can be seen schematically in fig. 4 and 3 is provided, so that the handle can only rotate within the required position range.

Further, the gear ratio of the pinion to the partial gear is 6: 54 or less.

The transmission ratio can ensure that when the partial gear rotates about 60 degrees, the pinion rotates at least one circle, so that the bottleneck is cut uniformly.

Further, the bottle holder and the guide wheel are arranged at intervals, so that the bottle holder and the guide wheel are positioned on different sides of the sand line.

Further, the large pressure cap is in threaded connection with the screw rod through a fixedly installed threaded sleeve 12.
