Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

By figure 1 to figure 4, the utility model discloses an go up briquetting 1 and briquetting 2 down, open the upper end of briquetting 2 down has a vertical mounting hole 3, it installs in briquetting 2's mounting hole 3 down and go up briquetting 1 and install first pressure spring 4 between the hole bottom to go up briquetting 1 slidable, it has a vertical through-hole 5 to go up to open on the briquetting 1, install a slidable montant 6 in the through-hole 5, a piston 7 that can reciprocate is installed to through-hole 5 upper end, there is the sliding friction damping between piston 7 and the through-hole 5, the lower extreme of montant 6 and the 3 bottom contacts of mounting hole, upper end and 7 lower extreme contacts of piston, piston 7 installs a second pressure spring 8 with its pushing down in the top, piston 7 upper end is fixed with a vertical elevation pole 9, can learn piston 7's high position through elevation pole 9.

A bolt 10 is screwed at the upper end of the through hole 5, the upper end of the second pressure spring 8 is in contact with the lower end of the bolt 10, the upper end of the elevation rod 9 penetrates through the bolt 10, and the pre-tightening force of the second pressure spring 8 can be adjusted by screwing the bolt 10.

The upper end of elevation pole 9 be fixed with a pilot pin 11, the upper end of going up briquetting 1 is fixed with a vertical scale 12, is carved with a scale mark 13 on the scale 12, when pilot pin 11 removed scale mark 13 position, piston 7 removed the lower extreme.

Friction plates 14 are respectively attached between the inner wall of the through hole 5 and the outer wall of the piston 7.

The bottom of the lower pressing block 2 is provided with a cushion rubber pad 15.

The utility model discloses when using, make the patient lie flat, the rescue personnel places this device in patient's thorax position, cushion rubber pad 15 and patient contact, avoid causing the fish tail to the patient body surface and weigh, then both hands are arranged in the upper end of last briquetting 1 and are pushed down the last briquetting 1 hard, go up briquetting 1 and push down the in-process, at first compress first pressure spring 4 to extreme position, in this process, piston 7 is pushed up to 6 upper ends of montant, make piston 7 overcome the effect of second pressure spring 8 and go up briquetting 1 and move upwards relatively, elevation pole 9 rises; after the first pressure spring 4 is compressed to the extreme position, go up briquetting 1 and promote briquetting 2 down and press patient's thorax 3-6 centimetres, then both hands remove the pressure, it upwards resets under the effect of first pressure spring 4 to go up briquetting 1, piston 7 resets downwards under the effect of second pressure spring 8, but because there is friction damping between piston 7 and the through-hole 5, consequently, piston 7 speed of resetting downwards needs certain time, pressure and friction damping through the second pressure spring 8 of debugging make this time and press the frequency and match, when locating pin 11 on elevation pole 9 moved down to scale mark 13 position, both hands application of force is pressed next time, so circulation.

When the friction force of the friction plate 14 between the piston 7 and the through hole 5 is reduced along with the use of the friction force, the bolt 10 is screwed upwards to reduce the pretightening force of the second pressure spring 8, and the downward moving time of the piston 7 is calibrated.

The utility model discloses a piston 7 moves down speed suggestion cardiopulmonary resuscitation's the frequency of pressing, can make the business personnel carry out cardiopulmonary resuscitation to the patient according to normalized frequency as far as and press, make patient the most probable obtain timely effectual treatment, improve the treatment success rate, this device does not need electronic components simultaneously, can place for a long time and not influence normal use, is applicable to the public place and is equipped with.
