Description

It can control lightweight heart pressing device according to pressing depth

Technical field

The utility model belongs to the technical field of medical first aid instrument, and in particular to a kind of to can control according to pressing depth light Type heart pressing device.

Background technique

Sudden cardiac arrest causes effective cardiac pump function and blood circulation to stop suddenly, body tissue's cell will be caused immediately serious Ischemic, anoxic and dysbolism will cause the irreversible damage of patient's brain He other people body organs in adult after 4~8 minutes Evil, therefore rescue must carry out against time, even critical significance may also be had very much by trying to be the first one minute or several seconds.

" Chinese cardiovascular disease report 2016 " display of national cardiovascular disease center publication, the annual sudden cardiac arrest sudden death in China Number of the infected is more than 500,000, wherein 60%~70% or more occurs (outside abbreviation institute), to need by around patient except medical institutions People implement external chest compression on the spot at the first time.

Cardiac compression is a kind of important measures of most commonly seen rescue cardiac arrest patient, it can be such that heart of patient restores Shrink and expansion, temporarily set up effective artificial circulation, make patient's heart, brain and whole body vitals obtain basic blood supply and Oxygen supply, and the autonomous beating of heart is further induced, it is rescued for patient until saving one's life provides possibility.

But external chest compression for according to pressing depth, compression frequency, start the indexs such as compressing time and have certain requirement: it is adult According to pressing depth require to be 5~6cm, old man according to pressing depth requires as 3~4cm, if according to pressing depth too greatly, be easy to cause fracture, Pneumothorax even stabs the problems such as heart lung, can also cause medical tangle, may be due to blood if according to pressing depth too small Internal circulating load is too small and loses resuscitation effect.

Traditional closed cardiac massage mainly includes electrical pressing, manually manually pressing, manual machine press three kinds of modes, under Evaluate and analyse one by one as follows in face:

Artificial manually closed cardiac massage mode physical demands is big, and manually continuously pressing was easy for ordinary people more than 2 minutes Fatigue and be short of physical strength, especially most of female nurse doctress even is also difficult to adhere to for two minutes, after pressing one two minutes Pressing quality just will appear and be decreased obviously, and cause according to pressing depth less and less adequate, and then be easy to cause Insufficience of blood flow.In addition, Even if just start to press not yet tired, manually pressing is also not easy to grasp according to pressing depth, for medical practitioner, in spite of Certain experiences, but control according to pressing depth also there is a continuing need for meticulous, it is slightly absent-minded to surpass width and cause to fracture, it is slightly tired Or will lead to very much depth deficiency with caution and fail, therefore is in a dilemma, necessarily affect the performance of movement；It is non-special outside for institute It even if the possibility that they have holds first-aider's card, but is in fact at most also the simple training by several hours for industry personage Instruction, was never reviewed later, more never really on human body by pressing through, therefore how to be controlled and is according to pressing depth even more Problem, common first-aider hesitate to sue and labour in street corner running into sudden cardiac arrest patient.And general public is to artificial unarmed The technical ability and gimmick of external chest compression require to be even more to feel advanced cumbersome, therefore inhibit most of general public study external chest compression The thought and courage of technology, the ratio for causing sudden cardiac arrest patient outside institute that can obtain external chest compression first aid is very low, effectively then Less, it has often lost best rescue opportunity when by patient transfer to hospital or doctor's arrival and has had no plan to make improvements.

For the electric cardiaopulmonary resuscitation apparatus such as Sa Bo due to equipment cost height, price is tens of thousands of or even hundreds of thousands of easily, is suitable only for advising The biggish hospital emergency rooms of mould, the department of non-emergency ward and basic hospital can not be equipped with, and the place other than hospital is unlikely There is Sa Bo electric cardiaopulmonary resuscitation apparatus.Even if, since these cardio-pulmonary resuscitation machines are cumbersome, being moved in larger hospital emergency rooms It is less convenient to move inconvenient and in place, installation, adjustment process, in place, installation, adjustment process usually want 2 minutes or so, and this 2 points To suspend the external chest compression to patient in clock, will necessarily extend patient without heartbeat, hypoxic-ischemic time, it might therefore lose most Good recovery opportunity, though installation after have higher external chest compression quality, can not also offset because time out it is longer caused by It is delayed negative effect, thus many doctors would rather manually press at the first time, also be reluctant to use Sa Bo in first time Cardio-pulmonary resuscitation machine, only after manually pressing is invalid for a long time, Sa Bo cardio-pulmonary resuscitation machine is for a long time just installed and used to all too, but As previously mentioned, can not achieve seamless interfacing, but seamed docking (needs from Sa Bo cardio-pulmonary resuscitation machine is manually manually converted to Suspend one two minutes).

According to pressing depth and tired in order to solve the problems, such as, people devise lever cardio-pulmonary resuscitation pressing device (manual machine Pressing device), lever type hand, which moves cardio-pulmonary resuscitation pressing device, cross bar support, pressing cross bar, press head, and wherein cross bar support is fixed It is motionless, and cross bar and press head then back and forth move up and down, while being additionally provided with fixed limit component, the effect of limit component To limit the extreme position that moves down of press head, when press head move down amplitude reach capacity position when, press cross bar Or press head cannot continue to move down due to the conflict by limiting component, according to pressing depth reaching the limit values (i.e. at this time According to pressing depth limiting value), to control according to pressing depth, it can prevent according to pressing depth super width, the mechanism of controlling depth limiting value Referred to as according to pressing depth regulating mechanism.In addition, in the prior art, it can also be by adjusting press head and pressing the opposite of both cross bars Vertical position and adjust according to pressing depth limiting value.Moreover, because lever cardio-pulmonary resuscitation pressing device uses lever construction, pressing ten It is point laborsaving, it solves the problems, such as tired, according to pressing depth insufficient, can achieve the purpose for adhering to pressing for a long time.However, on existing The pressing cross bar for stating lever cardio-pulmonary resuscitation pressing device needs one and is capable of fixing motionless balance pivot, and balance pivot needs again It is relatively fixed not with the splenium part of lying (hereinafter referred to as " back lie splenium part ", such as bed accessory or lying board) immediately below patients back It assembles and links together dynamicly, bed accessory or lying board could be utilized to fix the balance pivot；In addition, limitation pressing cross bar or press head The relatively fixed fixedly assembling of splenium part that is also required to lie with back of the limiting component of full swing amplitude links together, could shape At strong limit blocking effect.

Existing above-mentioned factor in turn results in following problems:

One, existing above-mentioned lever cardio-pulmonary resuscitation pressing device uses equally less convenient: must lift to patient and lever The back that fulcrum connects together is lain after splenium part, is possible to implement pressing, is lain above splenium part in addition, patient lifts to back Later, also patient is moved back and forth along the body short transverse (referred to as longitudinal) of patient, until making longitudinal position of heart of patient It sets and is accurately located at immediately below press head (after patient, which lifts to back, to lie above splenium part, although the lateral position of press head is also It can be adjusted along pressing cross bar, but the lengthwise position of press head is not adjustable, so patient can only be moved).In short It, existing lever cardio-pulmonary resuscitation pressing device before use, the horizontal position of press head is fixed, patient can only be lifted by Below pressure head and it is directed at heart, belongs to the mode of " press head is fixed and patient is mobile "；Since patient is in place, heart alignment, presses Depressor installation and adjustment and etc. require holding time, and these periods will equally stop the external chest compression to patient, because This practical application rate of existing lever cardio-pulmonary resuscitation pressing device in hospital is also very low；

Two, the entire lever pressing device splenium part (bed accessory) that must lie with back connects together and could use, overall volume Greatly, weight is also big, therefore is suitable only for being configured at hospital, is not suitable for the popularization of Pre-hospital emergency, is not suitable for being equipped in public places (public place does not have matched bed accessory) is less suitable for being provided to average family (too occupied space and at high cost).

As it can be seen that above-mentioned, now there are three types of first aid pressing side all Shortcomings, due to the above problems and limitation, in China The total number of persons of annual sudden cardiac arrest is about 50 Wan Renzhong, can effectively rescue less than 1%.Such as in China's Shanghai World Expo time of the meeting Between, 10 many cases sudden death patient has occurred, all fails to give treatment in time, none survival.But it reviews and occurs 5 in Aichi, Janpan World Expo Cardiac sudden death successfully rescues 4 patients and survives since field type facility is complete.Chinese doctors'associations deputy chairman, Beijing are abundant Outer cardiovascular disease director Gao Runlin is pointed out, can be at first if first-aid knowledge and first-aid apparatus can be popularized in the whole society Between to " Sudden Death " carry out CPR, then the rescue survival rate of cardiac arrest can rise to 30~50% or more.
