Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of CPR resilience relieving mechanism.
Background technology
During CPR external chest compression, it is ensured that the abundant resilience of thorax is very crucial factor after pressing every time,
Whether the abundant resilience of thorax can directly influence pressing resuscitation effect.At present, either mechanical compression or manual pressure, thorax
Resilience this process, is all, using thoracic cavity elasticity in itself, to be unclamped after certain depth is pressed, and breastbone automatic can recover because elastic
Position before.But, after pressing is fractured, the elasticity in thoracic cavity can be greatly reduced, and this will directly reduce thorax
Resilience discharges, and largely effects on pressing effect.
The content of the invention
Therefore, the technical problem to be solved in the present invention is to overcome existing CPR equipment above shortcomings, and then
A kind of CPR resilience relieving mechanism is provided.
To achieve the above object, the present invention 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 the downside of pressing palm, the lower surface of the press head is elastic surface, is suffered from for pressing
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 according to the compression frequency of the press head to the Stress control interacvity air-filling or pumping.
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 is 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.
Beneficial effects of the present invention：
CPR resilience relieving mechanism of the invention can produce part according to pressing depth, can increase according to pressing depth,
Breastbone will not be pressed simultaneously and produces extra breastbone pressing, i.e., be increased according to pressing depth while fracture is reduced；Generate ratio
Equilbrium position (referring to Fig. 1) more discharges, and preferably produces resilience, and generates local returning on skin between breastbone
Bullet, resilience effect more preferably, is more beneficial for CPR.Mechanism pulls resilience by double faced adhesive tape and vacuum, is actively released back into
Bullet, does not rely on 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 present disclosure is more likely to be clearly understood, below in conjunction with the accompanying drawings, the present invention is made further in detail
Thin explanation, wherein：
Fig. 1 be CPR resilience relieving mechanism of the invention be arranged on chest position structural representation (just
Beginning equilbrium position)；
Fig. 2 is structural representation of the CPR resilience relieving mechanism of the invention in pressing；
Fig. 3 is structural representation of the CPR resilience relieving mechanism of the invention in resilience.
Reference is expressed as in figure：
1- press heads；2- chests；3- pressure control cavities；4- air inlets；5- connectors.
Specific 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 is placed in the downside for pressing palm, namely this CPR resilience relieving mechanism
Can be used for 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 is in hemispherical or semiellipse chondritic, and the pressure control cavity 3 is closing chamber
Room, the side of the pressure control cavity 3 is provided with air inlet 4, and the air inlet 4 is connected with feeder, the feeder
Compression frequency according to the press head 1 is inflated or is evacuated in the pressure control cavity 3, the feeder can for 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 preferred double faced adhesive tape of connector 5, or other kinds of company
Fitting, such as silica gel piece.
Concrete operating principle is：
Referring to Fig. 2, during pressing, feeder, to pressure is increased in pressure control cavity 3, makes pressure by air inlet 4
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 is acted on downwards
Intensity breastbone higher, and from downwardly projecting between breastbone gap, it is to avoid breastbone sink, and then avoids because pressing force is spent
The fracture problem for producing greatly.
Referring to Fig. 3, in springback process is discharged, negative pressure will be extracted into pressure control cavity 3, makes the pressure in pressure control cavity
P2<Atmospheric pressure, drives thoracic cavity to pull up when such press head rises overally by double faced adhesive tape, and the more resiliences release displacements of generation-
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.Thus risen by the position of the elastic recoil of itself than thoracic cavity
More displacement h1+H1, generate more active releasing effects.
Certainly, in pressing process and release springback process, during to being injected in pressure control cavity or extract air, pressure control
Vacuum size appropriateness in chamber processed, can reach certain auxiliary and push and aid in resilience.
The CPR resilience relieving mechanism of the present embodiment can produce part according to pressing depth, can increase pressing deep
Degree, while will not press breastbone produces extra breastbone pressing, i.e., increased according to pressing depth while fracture is reduced；Generate
Than equilbrium position (referring to Fig. 1, now the pressure in pressure control cavity is P0) more releases, resilience is preferably produced, and
Local resilience is generated on skin between breastbone, resilience effect more preferably, is more beneficial for CPR.Mechanism is by two-sided
Glue and vacuum pull resilience, actively discharge resilience, do not rely on the natural resiliency of breastbone, so breastbone occurs fracture in time
Thorax resilience is not interfered with.
Above-mentioned specific embodiment is that technical scheme is explained in detail, the present invention not only only office
Be limited to above-described embodiment, it will be understood by those skilled in the art that it is every according to above-mentioned principle and spirit on the basis of the present invention
Improve, substitute, all should be within protection scope of the present invention.
