Description
Technical field
Technical field of medical instruments is the utility model is related to, more particularly to a kind of CPR resilience relieving mechanism.
Background technology
During CPR external chest compression, the abundant resilience of thorax is very crucial factor after ensureing pressing every time,
The whether abundant resilience of thorax can directly influence pressing resuscitation effect.At present, either mechanical compression or manual pressure, thorax
This process of resilience, all it is to utilize the elasticity of thoracic cavity in itself, is unclamped after certain depth is pressed, breastbone can be because of elastic automatic recovery
To position before.But after pressing is fractured, the elasticity in thoracic cavity can greatly reduce, and this will directly reduce thorax
Resilience discharges, and largely effects on pressing effect.
Utility model content
Therefore, the technical problems to be solved in the utility model is to overcome existing CPR equipment above shortcomings,
And then provide a kind of CPR resilience relieving mechanism.
To achieve the above object, the utility model uses following technical scheme：
A kind of CPR resilience relieving mechanism, it includes press head, and the press head is connected to device for resuscitating heart and pulmones
Pressing piston rod end or be placed in pressing palm downside, the lower surface of the press head be elastic surface, for press trouble
Person thoracic cavity；The pressure control cavity of indent, the pressure are provided between the lower surface of the press head and the press head body
Control chamber is closed chamber, and the side of the pressure control cavity is provided with air inlet, and the air inlet is connected with feeder, institute
Feeder is stated to inflate or be evacuated to the Stress control intracavitary according to the compression frequency of the press head.
Preferably, the lower surface of the press head is provided with connector, lower surface and the chest table of the connector
Face bonding connection, the upper surface of the connector are fixedly connected with the lower surface of the press head.
Preferably, the connector is double faced adhesive tape.
Preferably, the pressure control cavity is in hemispherical or semiellipse chondritic.
The beneficial effects of the utility model：
CPR resilience relieving mechanism of the present utility model can produce part according to pressing depth, and it is deep can to increase pressing
Degree, while breastbone will not be pressed and produce extra breastbone pressing, i.e., added according to pressing depth while reducing and fracturing；Generate
More discharged than equilbrium position (referring to Fig. 1), preferably produce resilience, and generated on the skin between breastbone local
Resilience, resilience effect is more preferable, is more beneficial for CPR.Mechanism pulls resilience by double faced adhesive tape and vacuum, actively discharges
Resilience, independent of the natural resiliency of breastbone, so the fracture of breastbone generation in time does not interfere with thorax resilience yet.
Brief description of the drawings
In order that content of the present utility model is more likely to be clearly understood, below in conjunction with the accompanying drawings, the utility model is made
Further details of explanation, wherein：
Fig. 1 is the structural representation that CPR resilience relieving mechanism of the present utility model is arranged on chest position
(initial rest position)；
Fig. 2 is structural representation of the CPR resilience relieving mechanism of the present utility model in pressing；
Fig. 3 is structural representation of the CPR resilience relieving mechanism of the present utility model in resilience.
Reference is expressed as in figure：
1- press heads；2- chests；3- pressure control cavities；4- air inlets；5- connectors.
Embodiment
Referring to Fig. 1, a kind of CPR resilience relieving mechanism, it includes press head 1, and the press head 1 is connected to the heart
The end of the pressing piston rod of lung recovery device or the downside for being placed in pressing palm, namely this CPR resilience relieving mechanism
It can be used to indirect labor's CPR, it can also be used to assistive device formula device for resuscitating heart and pulmones.The lower surface of the press head 1 is
Elastic surface, for pressing chest 2；Indent is provided between the lower surface of the press head 1 and the press head body
Pressure control cavity 3, the pressure control cavity 3 are in hemispherical or semiellipse chondritic, and the pressure control cavity 3 is closing chamber
Room, the side of the pressure control cavity 3 are provided with air inlet 4, and the air inlet 4 is connected with feeder, the feeder
Inflate or be evacuated into the pressure control cavity 3 according to the compression frequency of the press head 1, the feeder can be air pump or
Other sources of the gas, as long as it can be supplied and be evacuated according to the frequency of CPR.Because the lower surface of press head 1 is
Elastic surface, when the pressure in pressure control cavity 3 changes, the lower surface of press head can be raised or sunken.The press head 1
Lower surface be provided with connector 5, lower surface and the chest surface bonding connection of the connector 5, the connector 5
Upper surface is fixedly connected with the lower surface of the press head 1；The 5 preferred double faced adhesive tape of connector or other kinds of company
Fitting, such as silica gel piece.
Concrete operating principle is：
Referring to Fig. 2, during pressing, feeder increases pressure by air inlet 4 into pressure control cavity 3, makes pressure
Pressure P1 in control chamber>Atmospheric pressure, such press head 1 with press device or it is artificial press down on depth H while, press head
The meeting of 1 lower surface ejects to form the according to pressing depth h that a protrusion produces part downwards, can be avoided when the protrusion acts on downwards
The higher breastbone of intensity, and from downwardly projecting between breastbone gap, avoiding breastbone sink, and then avoids because pressing force is spent
Big and caused fracture problem.
Referring to Fig. 3, in springback process is discharged, negative pressure will be extracted into pressure control cavity 3, makes the pressure of Stress control intracavitary
P2<Atmospheric pressure, drive thoracic cavity to pull up by double faced adhesive tape when such press head rises overally, produce more resiliences release displacements-
H1 ("-" number represent upward displacement), while the elastic surface of press head lower surface is when pressure is negative pressure in pressure control cavity 3,
Depression is produced, this can just produce the release displacement-h1 of part.The position for the elastic recoil for thus passing through itself than thoracic cavity rises
More displacement h1+H1, generate more active releasing effects.
Certainly, in pressing process and release springback process, when being injected to Stress control intracavitary or extracting air, pressure control
The vacuum size appropriateness of intracavitary processed, the auxiliary that can reach certain push and aided in resilience.
The CPR resilience relieving mechanism of the present embodiment can produce part according to pressing depth, and it is deep can to increase pressing
Degree, while breastbone will not be pressed and produce extra breastbone pressing, i.e., added according to pressing depth while reducing and fracturing；Generate
More discharged than equilbrium position (referring to Fig. 1, now the pressure of Stress control intracavitary is P0), preferably produce resilience, and
Local resilience is generated on skin between breastbone, resilience effect is more preferable, is more beneficial for CPR.Mechanism passes through two-sided
Glue and vacuum pull resilience, actively discharge resilience, independent of the natural resiliency of breastbone, so fracture occurs for breastbone in time
Thorax resilience is not interfered with.
Simply the technical solution of the utility model is explained in detail for above-mentioned embodiment, and the utility model is not
Above-described embodiment is only limited only to, it will be understood by those skilled in the art that every according to above-mentioned principle and spiritual in this practicality
Improvement, replacement on novel foundation, all should be within the scope of protection of the utility model.
