Lower end is fixedly connected with the first briquetting.
The application method of the utility model is described below:
(1), it allows patient to lie low, the pressing device is then placed on victim, so that compression bar is placed in above patient's heart;
(2), according to the figure of patient, the height of compression bar is adjusted by hoisting mechanism, until the first briquetting and patient body
Contact;
(3), then compression bar is driven to move up and down by pressing driving mechanism, then compression bar moves down upwards to be primary,
The mobile number of compression bar should be controlled at 60-100 beats/min, can carry out cardiac compression first aid to patient in this way;
(4), when patient is adult, the second briquetting is mounted on the first briquetting, at this time the size of the first, second briquetting
With human adult heart sizableness;When patient is minor, the second briquetting is unloaded from the first briquetting, at this time the first briquetting
It is suitable with the cardiac size of minor;It, can be to avoid compressing patient's heart in this way when carrying out cardiac compression first aid to patient
Except other organs.
The pressing device can use in the emergency room of hospital, can also use in outgoing first aid, at this time will be by piezoelectricity
Machine changes squeeze grip into.Moving up and down for compression bar is driven by shaking squeeze grip in this way, this is relative to directly right with hand
Patient carries out cardiac compression and wants laborsaving.
For within the hospital using the pressing device when facilitate the position of pressing device to adjust, store, as shown in figure 12, in pedestal
Lower part is equipped with translation lead screw 13 and guide rod 12, and the two is arranged in parallel.Translation lead screw is connect with whorl of base, guide rod and bottom
Seat is slidably connected, and is respectively equipped with trunnion 11 at the both ends of translation lead screw, is also respectively equipped with trunnion 11, trunnion at the both ends of guide rod
With translation lead screw rotation connection, trunnion is fixedly connected with guide rod.It is fixed with handle 14 on translation lead screw, shakes translation
When handle, pedestal can be driven to be oppositely oriented the movement of bar.
The pressing device is before pressing patient's heart, and the first briquetting or/and the second briquetting are contacted with patient body always, such as
Shown in Fig. 7, the height that compression bar is adjusted before pressing contacts the first briquetting with patient body, and it is zero that pressure spring, which bears pressure, at this time;
As shown in figure 8, the first briquetting or/and the second briquetting and 6 body of patient occur to squeeze and are pressed into patient's body when pressing down on compression bar
Body 3-5cm;As shown in figure 9, with the rotation of crank, when compression bar return, the deformation of pressure spring is gradually become smaller.Until compression bar returns to just
When beginning position, the first briquetting is still contacted with patient body, this with manually manually to patient carry out cardiac compression first aid when operation
Mode is identical, more can guarantee validity when cardiac compression first aid.External in the first, second briquetting wraps up silica gel, can keep away
Exempt from that patient body is caused to abrade.
It is steady when pressing to guarantee, as shown in Figure 10, four extension rods 42, four extensions are fixed in the lower end of compression bar
Bar is located on same circumference, is equipped with a pressure spring in the outside of each extension rod, in this way when compression bar pushes, can make the
One briquetting and patient's face contact, and then guarantee steady when pressing.
It may be implemented that the second briquetting is threadably mounted at the first pressure to minor's cardiac compression first aid by the first briquetting
Cardiac compression first aid can be carried out to adult after on block, it is complicated to avoid the various sizes of briquetting bring installation of two kinds of setting
Property.First, second briquetting thread connecting mode can realize disassembly and installation between the two, certainly between the two quickly
It can be by the way of clamping connection.
Due to the size of crank be it is fixed, the every rotation of crank one week, the distance that compression bar moves down is fixed, therefore pressure spring
Coefficient of elasticity difference when, the decrement of pressure spring is just different.Needs when to meet to minor's cardiac compression, such as Figure 13 institute
Show, is threadedly coupled between the upper end and compression bar of extension rod and the upper end of extension rod protrudes into compression bar one section, in the upper end of extension rod
Be fixed with baffle 421, the upper end of pressure spring is fixedly connected with baffle, be fixed with fixed block 54 in the lower end of pressure spring, the fixed block with
It is threadedly coupled between first briquetting.When needing to carry out cardiac compression first aid to minor, more small coefficient can be replaced
Pressure spring.
The pressing device compared with prior art, is not only able to satisfy the needs to human adult heart pressing first aid, but also can be to teenage
People carries out cardiac compression first aid, and while pressing adult and minor can press different depth, to guarantee heart
Press the validity of first aid;Compression bar is driven to move down realization to cardiac compression, relative to existing manually straight by electronic mode
The mode of pressing is connect, it is more time saving and energy saving;The driving force that compression bar moves down can also be other than electronic manually, i.e., in the second snail
Squeeze grip is fixed on the worm shaft of bar, it is more laborsaving for directly pressing patient's heart, and use environment multiplicity;
The setting of first, second briquetting surface silica gel, can prevent the scratch to patient, and the first, second briquetting always with patient's body
Body contact, it is consistent with operation technique when unarmed progress cardiac compression, and then ensure that the validity of cardiac compression first aid;First pressure
Four pressure springs are set between block and compression bar, and four pressure springs are uniformly arranged in the circumferential direction, it is ensured that it is steady when pressing, also guarantee
The validity of cardiac compression first aid.
