Description

It can the intuitive lightweight heart pressing device of observing and controlling according to pressing depth

Technical field

The utility model belongs to the technical field of medical first aid instrument, and in particular to it is a kind of can intuitive observing and controlling according to pressing depth Lightweight 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.

External chest 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 blood circulation, make the whole bodies vitals such as the heart, brain 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 also has certain requirement to according to pressing depth equal other than the implementation as early as possible that requires to race against time: Adult compressions' depth requirements are 5~6cm, and child old man according to pressing depth requires to be 3~4cm, if according to pressing depth too small, due to Blood circulation amount is too small and may lost resuscitation effect;If according to pressing depth too big, it be easy to cause fracture, pneumothorax, even pierces The problems such as sad dirty lung, can cause medical tangle.

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, pressing quality just will appear and be decreased obviously, and cause according to pressing depth less and less adequate, and then is easy to cause and robs Failure is rescued, especially most of female nurse doctress even is also difficult to adhere to for two minutes.In addition, even if just starting pressing not yet When tired, manually pressing is also not easy to grasp according to pressing depth, and for medical practitioner, in spite of certain experiences, but control is pressed Press 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 caution very much Depth is insufficient and fails, therefore in a dilemma, necessarily affects the performance of movement.Statistics shows, external chest compression case in practice The ratio of fracture is caused to be up to 20~30% or so in example.For the layman outside hospital, even if the possibility that they have Hold first-aider's card, but be at most also in fact the simple training by several hours, did not always review later, more always Not really on human body by pressing through, therefore how to control according to pressing depth is even more a hang-up, so that common first-aider is on road On when seeing sudden cardiac arrest person, generally dare not also go forward to sue and labour rashly.And general public is according to pressing depth even more for how to control Feel unable to guarantee, self-distrust goes study external chest compression technology, so sudden cardiac arrest patient can obtain in time outside institute, China The ratio of rescue is very low, effective less, often when by patient transfer to hospital or doctor's arrival, has lost most Good rescue opportunity and have no plan to make improvements.

The electric cardiaopulmonary resuscitation apparatus such as Sa Bo equipment costs is high, and price is tens of thousands of or even hundreds of thousands of easily, be suitable only for scale compared with Big hospital emergency rooms, the department of non-emergency ward and basic hospital can not be equipped with, and unlikely there is Sa in the place other than hospital Vigorous electric cardiaopulmonary resuscitation apparatus.Even if, since these cardio-pulmonary resuscitation machines are cumbersome, movement is not in larger hospital emergency rooms It is convenient and in place, installation, adjustment process, according to pressing depth setting procedure is less convenient, in place, installation, is according to pressing depth set adjusting Determine process and usually want 2 minutes or so, and this 2 minutes process will suspend the external chest compression to patient, it is inevitable therefore to extend Patient without heartbeat, hypoxic-ischemic time, optimal recovery opportunity may be lost, though installation after have higher external chest compression matter Amount, can not also offset because the set-up time it is longer caused by delay negative effect, thus most of doctor would rather be at the first time It is manually pressed, is also reluctant in first time using Sa Bo cardio-pulmonary resuscitation machine, it is real only after manually pressing is invalid for a long time For a long time just enabling very much Sa Bo cardio-pulmonary resuscitation machine, but as previously mentioned, be converted to Sa Bo cardio-pulmonary resuscitation machine from artificial manually pressing, and It can not achieve seamless interfacing, but seamed docking (namely needing to suspend in place, installation, debug time in two minutes or so).

In order to solve the problems, such as to grasp according to pressing depth, people devise Manual mechanical cardio-pulmonary resuscitation pressing device again, existing Manual mechanical cardio-pulmonary resuscitation pressing device has cross bar support, pressing cross bar, press head, and wherein cross bar support is fixed, and Pressing cross bar and press head then back and forth move up and down, while being additionally provided with fixed limit component, and the effect of limit component is Maximum amplitude value that limitation press head moves down (according to pressing depth limiting value, referred to as according to pressing depth value or according to pressing depth), when pressing Pressure head move down amplitude reach setting numerical value when, pressing cross bar cannot continue due to the conflict by limiting component downwards It is mobile, reach according to pressing depth limiting value, so that control is according to pressing depth, prevents from according to pressing depth surpassing width, the position of above-mentioned limit component Both adjustable or press head and pressing cross bar vertical relative position are adjustable, to adapt to the difference of patient's chest depth And it is accurate to control according to pressing depth limiting value, therefore this mechanism is known as according to pressing depth regulating mechanism.It is so-called according to pressing depth, also known as press Press depth limit value, refer to during pressing, just contacted from press head patient chest (at this time press head and patient chest it Between pressure when being zero), until when press head does not continue to downlink, the vertically movable distance of press head.

In order to measure according to pressing depth, Manual mechanical cardio-pulmonary resuscitation pressing device must be equipped with measuring appliance, and measuring appliance includes surveying Measuring device fixed part and measuring appliance movable part, wherein measuring appliance movable part connects together with pressing cross bar and swings simultaneously, and measures Device fixed part then connects together with fixed cross bar support and fixed, by dekkor movable part relative to survey The mobile range of measuring device fixed part, so that it may calculate the pressing amplitude of press head.When work, measuring appliance fixed part needs to carry on the back with patient Back immediately below portion splenium part (hereinafter referred to as " back lie splenium part ", such as bed accessory or bed board, back backing plate) of lying is relatively solid It is fixed fixedly to link together, just it is able to achieve the fixed of measuring appliance fixed part；Equally, the balance pivot for pressing cross bar also needs Lying with back, splenium part is relatively fixed fixedly to be fitted together, could utilize back lie splenium part hold pressing cross bar thick stick Bar fulcrum；The limiting component of limitation pressing cross bar full swing amplitude is also required to the relatively fixed fixedly group of splenium part of lying with back It is fitted together, strong blocking position-limiting action could be formed.Therefore, existing above-mentioned Manual mechanical heart pressing device exists again Following problems:

One, it lies above splenium part, is possible to before use, patient must be lifted to the back to connect together with balance pivot Implement pressing, in addition, patient lifts to after back lies above splenium part, although the lateral position of press head can also be along pressing Cross bar is adjusted, but the lengthwise position of press head is not adjustable, so (can only also known as indulge along the body short transverse of patient To) patient is moved back and forth, until being accurately located at the lengthwise position of heart of patient immediately below press head；In short, existing manual Mechanical cardio-pulmonary resuscitation pressing device is before use, belong to the mode of " press head is fixed and patient is mobile ", installation, patient are just Position, heart alignment are all relatively time-consuming, generally require 2 minutes or so.

Two, it is as follows using measuring appliance to control method according to pressing depth for existing machinery formula pressing device: before starting pressing, make by Pressure head naturally droops contact heart of patient, wouldn't exert oneself at this time, and pressing force zero, pressing amplitude is also zero, observes quarter at this time Degree (scale at this time is known as pressing initial reading)；Then, start firmly to press, be limited component blocking when press head is moved to When, pressing terminal reading is subtracted pressing initial reading, so that it may the according to pressing depth limit be calculated by record pressing terminal reading Value；If according to pressing depth limiting value does not meet sets requirement, the position of limit component is readjusted, is calculated again, until pressing Pressure depth limit value meets sets requirement.In the above process, need to remember that two values (read by pressing initial reading and pressing terminal Number), and it is all different according to the difference of patient's chest depth for pressing initial scale value and pressing terminal scale value, is random number (being changed according to patient's chest depth difference), it is impossible to just be shown as according to pressing depth limiting value or the according to pressing depth integer of limiting value Multiple is generally also impossible to just be shown as zero；Therefore, the according to pressing depth reading of existing pressing device measuring appliance is not intuitive, needs Conversion, is unfavorable for being rescued against time, and conversion error is also easy to when flurried；

Three, the entire mechanical 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, and without being suitably equipped with, (public place is not matched in public places Bed accessory), it is less suitable for being provided to average family (due to too occupied space and at high cost and be difficult to be equipped with).

As it can be seen that existing above-mentioned three kinds of first aid pressing sides all Shortcomings, every in China due to the above problems and difficulty The total number of persons of year sudden cardiac arrest is about 50 Wan Renzhong, can rescue back less than 1%.During China's Shanghai World's Fair, hair 10 many cases sudden death patient has been given birth to, has all failed to give treatment in time, none survival.But it reviews and 5 hearts occurs in Aichi, Janpan World Expo Sudden death, successfully rescues 4 patients and survives since field type facility is complete.Member of Chinese Academy of Engineering, Chinese doctors'associations pair President, the abundant outer cardiovascular disease director Gao Runlin in Beijing are pointed out, if first-aid knowledge and first-aid apparatus can be popularized in the whole society, Can first time to " Sudden Death " carry out CPR, then the rescue survival rate of cardiac arrest can rise to 30~50% with On.

Utility model content

A kind of intuitive lightweight of observing and controlling according to pressing depth of energy is provided the purpose of the utility model is to overcome disadvantages mentioned above Heart pressing device, the easy observing and controlling of its energy are according to pressing depth worth, easy to operate, saving physical strength, and have not only been suitable for hospital but also be suitable for house Front yard and public place are universal.

Its purpose can be realized by following scheme: a kind of intuitive lightweight heart pressing device of observing and controlling according to pressing depth of energy, packet The handle for including press head, pressing cross bar, holding for rescuer's wrist, press head link together with pressing cross bar, press cross bar First end be connected with support member, which is characterized in that the second end for pressing cross bar is connected with vertical floating and bottoms out bar, float Bar is bottomed out to move up and down in company with press head and pressing cross bar；Press support member, the pressing cross bar, pressing cross bar of cross bar first end The floating of second end bottoms out the character "door" form structure of bar composition semi-surrounding, wherein pressing cross bar is located at the top of character "door" form structure, presses The floating of the support member and pressing cross bar second end of cross bar first end is pressed to bottom out the left and right two that bar is located at character "door" form structure Side；The character "door" form structure of the semi-surrounding forms complete open opening in bottom, the direction of opening downward, the transverse direction of opening Width is greater than human chest width, and the space of character "door" form structure semi-surrounding is sufficient to accommodate human chest；Press cross bar first end Support member, which is not provided with, carries out the fastening link mechanism of fastening connection, pressing cross bar second end with patients back splenium part of lying It floats to bottom out bar and be also not provided with and carries out the fastening link mechanism of fastening connection, i.e. pressing cross bar the with patients back splenium part of lying It is fixedly connected one that the support member of one end, the floating for pressing cross bar second end bottom out bar splenium part of not lying with patients back It rises；Opposite sides of the handle arrangements in press head；The press head is moved up and down in company with the handle of side at least within；

The lower part that floatings of the pressing cross bar second end bottoms out bar is loosely arranged with measurement loop bar, measurement loop bar with Floating is bottomed out and freely opposite can be slided between bar, is bottomed out in bar the two in measurement loop bar and floating, the surface of one of them is set There is length scale, another one is formed with scale reading indicate indicator, and length scale indicated by the scale reading indicate indicator is read Number reflection measurement loop bar and floating bottom out the distance that is staggered of both bars, or move equal to described be staggered apart from corresponding press head Dynamic distance.

So-called measurement loop bar and floating bottom out the distance that is staggered of both bars, refer to that measurement loop bar bottom end point and floating bottom out bar The distance offset vertically between the point of bottom end.When measuring loop bar and floating bottoms out the sliding relatively of both bars, loop bar and floating are measured Bottom out the distance constantly variation that is staggered of both bars, length scale reading constantly variation indicated by scale reading indicate indicator.

Splenium part is lain in the support member bottom of pressing cross bar first end and patients back or ground is always maintained at contact In the case of, when press head, pressing cross bar and floating bottom out bar while swinging up and down, then press head amplitude of fluctuation will be bottomed out with floating The amplitude of fluctuation of bar becomes proportional relationship (lever proportionate relationship).It is so-called with it is described be staggered apart from corresponding press head it is mobile away from From, in the case where referring to that splenium part of lying in the support member bottom of pressing cross bar first end with patients back is always maintained at contact, When press head, pressing cross bar and floating bottom out bar while swinging up and down, and floats and bottom out the swinging distance of bar and be equal to and measure loop bar With float bottom out both bars be staggered apart from when, the corresponding swinging distance of press head.

Before formal pressing starts, when press head is placed on naturally above patient chest (not apply pressure, at this time press head with Extraneous pressure between patient chest is that zero), floating bottoms out bar bottom end and suspends (be detached from back lie splenium part or cushion block), and measures For loop bar since the effect of self gravity will naturally droop, measurement loop bar bottom end point holding bottoms out that (contact patients back is lain splenium part Or cushion block)；Therefore, the measurement loop bar under this state and floating bottoms out the distance that is staggered of both bars, that is, floats and bottom out bar Bottom end point relative to back lie distance that splenium part or cushion block suspend (suspension distance referred to as original suspension under this state away from From), and original suspension distance will determine that the press head under the state is capable of the maximum distance (i.e. according to pressing depth limiting value) of downlink, Original suspension distance and according to pressing depth limiting value direct proportionality.Therefore, press head is placed on trouble naturally before above-mentioned pressing starts Initial reading when above person's chest is exactly the original suspension distance for reflecting floating and bottoming out bar in fact, or more directly Pressing distance (namely according to pressing depth limiting value) practical equal to press head.Each downward push movement terminal state, by It bottoms out bar in floating to bottom out, it is zero that floating, which bottoms out distance between bar bottom end point and measurement loop bar bottom end point, therefore presses terminal and read Number is zero.
