Description

Lever type cardiopulmonary resuscitation pressing device convenient to store and carry

Technical Field

The invention belongs to the technical field of medical first-aid appliances, and particularly relates to a lever type cardiopulmonary resuscitation pressing device.

Background

Sudden cardiac arrest results in sudden cessation of effective cardiac pump function and blood circulation, which immediately causes severe ischemia, hypoxia and metabolic disturbance of systemic tissue cells, and after 4-8 minutes, irreversible damage to the brain and other vital organs and tissues of the patient, so rescue must be performed in minutes and seconds, even a minute or a few seconds of preemption can be of great significance.

According to the report 2016 of cardiovascular diseases in China issued by the center of cardiovascular diseases, the number of sudden cardiac death caused by sudden cardiac arrest in China exceeds 50 ten thousand per year, more than 60% -70% of the sudden cardiac death occurs outside medical institutions (outside hospitals for short), and chest compressions need to be carried out on site by people around patients at the first time.

Chest compressions are one of the most common important measures for rescuing patients suffering from cardiac arrest, and chest compressions can restore the heart of the patient to contract and expand, temporarily establish effective artificial blood circulation, enable important organs of the heart, brain and whole body of the patient to obtain basic blood supply and oxygen supply, further induce autonomous pulsation of the heart and provide possibility for rescuing the patient until life is saved.

Chest compressions, however, have certain requirements for compression depth, start compression time, etc: 1. the more slowly the compression is initiated, the more severe the irreversible damage to the patient's brain and other vital organs and tissues, so chest compressions must be performed in seconds, even a minute or a few seconds of preemption can be significant; 2. the pressing depth of an adult is required to be 5-6 cm, the pressing depth of an old and a child is required to be 3-4 cm, if the pressing depth is too large, the problems of fracture, pneumothorax, even stabbing heart and lung and the like are easily caused, medical disputes can be caused, and if the pressing depth is too small, the resuscitation effect can be lost due to too small blood circulation.

Traditional chest heart presses mainly includes electric press, artifical bare-handed press, manpower lever mechanical press three kinds of modes, and the following is examined respectively.

The electric cardiopulmonary resuscitation machine such as Sab and the like is only suitable for emergency rooms of hospitals with larger scale, departments of non-emergency rooms and primary hospitals because of high equipment cost and quick price, and the electric cardiopulmonary resuscitation machine such as Sab and the like is more unlikely to be equipped in places other than hospitals. However, even in emergency rooms of hospitals with larger scale, because these cardiopulmonary resuscitation machines are heavy and inconvenient to move, and the seating, installation and adjustment processes are not convenient, usually about 2 minutes are needed, the chest compression of the patient is suspended for about 2 minutes, the non-heart beat and ischemia hypoxia time of the patient is inevitably prolonged, the optimal resuscitation time can be lost, and even if the chest compression quality is high after installation, the delayed negative effect caused by the longer installation time can not be offset, so that many doctors prefer to press by bare hands at the first time, and do not want to use the saber cardiopulmonary resuscitation machine at the first time, and only after the long-time bare hand pressing is invalid, the saber cardiopulmonary resuscitation machine is installed and used when the chest compression is actually too tired, but as described above, the manual bare hand is converted into the saber cardiopulmonary resuscitation machine, seamless butt joint cannot be realized, and the seam butt joint (about two minutes need to be suspended).

Traditional manual freehand compressions are accomplished by pressing down on the mid-lower portion of the sternum with both hands. However, the manual pressing mode is high in physical consumption, and common people can easily fatigue and have poor physical strength by continuously pressing for more than 2 minutes, the pressing quality can be obviously reduced, the pressing depth is more and more insufficient, and further rescue failure is easily caused. In particular, most women nurses are difficult to adhere to even two minutes. In addition, even when the initial pressing is not tired, the pressing depth is not easy to grasp by bare hand, and for a professional doctor, the control of the pressing depth always needs to be carefully performed in spite of a certain experience, and the fracture is caused by overstepping when the person walks away, and the failure is caused by insufficient depth when the person is tired or careful; for non-professionals outside the hospital, even if they possibly hold emergency officers, at best, the emergency officers are simply trained for a few hours, never review later, and never really press on the human body, so how to control the pressing depth is a great difficulty, and even if the ordinary emergency officers encounter cardiac arrest patients on the street, the ordinary emergency officers are not dared to rescue before the trade. The ordinary people have more daunting requirements on the manual chest compression manipulation, so that the thoughts and courages of most ordinary people in learning chest compression technology are inhibited, the ratio of chest compression first aid to be obtained by patients suffering from sudden cardiac arrest outside the hospital is low, the effective rate is less, and the time for the patients to transfer to a hospital or the arrival of doctors is often shortened, and the optimal rescue opportunity is lost and the patients get back to the operation.

The existing manpower lever cardiopulmonary resuscitation presser is provided with a cross rod support, a pressing swing rod and a pressing head, wherein the cross rod support is fixed, the cross rod and the pressing head reciprocate up and down, a fixed limiting member is also arranged at the same time, the limiting member acts to limit the limiting position of the downward movement of the pressing head, when the downward movement amplitude of the pressing head reaches the limiting position, the pressing swing rod or the pressing head cannot continue to move downwards due to the interference of the limiting member, and the pressing depth at the moment reaches the limiting value, so that the pressing depth (namely the pressing depth limiting value) is controlled, and the excessive pressing depth can be strictly prevented. In addition, the pressing depth limit value can be adjusted by adjusting the relative vertical positions of the pressing head and the pressing swing rod. Moreover, because the lever type cardiopulmonary resuscitation pressing device adopts a lever structure, the pressing is very labor-saving, the problems of fatigue and insufficient pressing depth are solved, and the aim of long-time lasting pressing can be fulfilled.

However, the pressing swing rod of the conventional lever type cardiopulmonary resuscitation pressing device needs a fixed lever fulcrum, and the lever fulcrum needs to be assembled together with a lying part (hereinafter referred to as a "back lying part" for short) under the back of the patient in a relatively fixed manner, so as to stabilize the lever fulcrum of the pressing swing rod; similarly, the limiting component for limiting the maximum swing amplitude of the pressing swing rod or the pressing head needs to be assembled together with the back lying component relatively fixedly so as to form a powerful limiting blocking effect. Therefore, the lever type cardiopulmonary resuscitation pressing device has the following problems:

1. before use, the patient must be lifted onto the back lying part connected with the lever fulcrum to possibly implement pressing, in addition, after the patient is lifted onto the back lying part, although the transverse position of the pressing head can be adjusted along the pressing swing rod, the longitudinal position of the pressing head can not be adjusted, so the patient can only be moved back and forth along the height direction of the patient until the longitudinal position of the heart of the patient is precisely positioned under the pressing head; in summary, the existing manual mechanical cardiopulmonary resuscitation pressing device belongs to a mode of 'fixing a pressing head and moving a patient' before pressing, the installation, the positioning and the heart alignment of the pressing head and the patient are time-consuming, and the chest compression of the patient is suspended in the process, so that the actual use rate of the existing lever type cardiopulmonary resuscitation pressing device in a hospital is low.

2. The whole lever-type presser must be connected with a back lying part (bed) for use, the transverse width must be larger than the chest width of a human body, at least more than 60CM is needed, the whole volume is large, the weight is also large, and therefore, the lever-type presser is only suitable for being configured in a hospital, is not suitable for popularization of emergency treatment outside the hospital, is not suitable for being configured in public places (beds which are not matched in public places, and the traditional lever-type presser is difficult to hang on a wall of the public places like a first-aid kit), and is not suitable for being configured in ordinary families (because of too occupied space).

Therefore, the three existing first-aid pressing parties are insufficient, and due to the problems and difficulties, the total number of people suffering from sudden cardiac arrest per year in China is about 50 ten thousand, and the number of people can be saved by less than 1%. During the world exposition of the Shanghai in China, more than 10 sudden death patients occur, and none of the sudden death patients can survive in time. However, the reverse observation is that 5 cases of sudden cardiac death occur in the Japanese love world exposition, and 4 cases of patients survive due to the complete on-site facilities. The institute of Chinese doctors and the institute of Cardiovascular diseases hospital Hospital, beijing Fu, gao Runlin indicate that if the first aid knowledge and first aid equipment can be popularized in the whole society, the sudden death can be recovered to the heart and lung at the first time, and the survival rate of the sudden cardiac arrest can be increased to 30-50%.

The back lying part of the patient refers to a part which contacts with the back of the patient when the patient lies flat. When a patient lies on the bed, the back lying part of the patient refers to a bed; the patient's back lying part refers to the sheet-like object when the patient lies on the sheet-like object; in special cases, the back lying part may also be referred to as ground when the patient is lying on the ground.

When the invention is used, a patient lies on the back lying part, and the rescuer is positioned on the side face of the chest of the patient and faces the patient, so that the left-right direction of the patient corresponds to the front-back direction of the rescuer.

In this application, the definition of the lateral and longitudinal directions of a product is based on the direction of the patient in the state of use of the product. The lateral direction, i.e., the left-right direction, is the direction of the width of the patient's body (i.e., the chest width) when the patient receives cardiac resuscitation compressions. The longitudinal direction, i.e., the anterior-posterior direction, is the direction of the height of the patient's body when the patient is under cardiac resuscitation compressions. The vertical direction refers to the chest thickness direction of the patient.

The floating bottom rod belongs to a strip-shaped member, and is named as floating because the floating bottom rod moves up and down during working; when the rod descends to the limit position, the bottom end point of the rod contacts with the cushion block or the back lying part, so the rod is named as 'bottoming' and is named as 'floating bottoming rod' in the whole.

when in use, a patient lies on the back lying part 81, a rescuer and an assistor are respectively positioned at the left side and the right side of the chest 8 of the patient and face each other, the first section 11 of the pressing swing rod is inserted into the insertion hole 14 of the second section 12 of the pressing swing rod, the whole door-shaped pressing device is reversely buckled on the chest 8 of the patient, the pressing head 1 is aligned with the heart of the patient and naturally placed above the heart of the patient, the assistor holds the first fixed handle 31 and the second fixed handle 32 by hands, the whole hand-held bracket 4 is pressed to fix the position, the whole hand-held bracket cannot transversely topple or longitudinally topple, cannot shift, the superposition quantity of the cushion blocks 6 is regulated, the vertical distance between the upper surface of the cushion block 6 and the bottom end of the floating bottom rod 5 is equal to the limit value of the pressing depth multiplied by a proportionality coefficient (the proportionality coefficient is a/e, a is the transverse distance from the bottom end of the floating bottom rod to the pendulum shaft, e is the transverse distance from the pressing head to the pendulum shaft, the proportionality coefficient is determined when the first section of the pressing pendulum rod is inserted into the second section 12 of the pressing pendulum rod, and a/e can be designed to be 2 for simplicity after the presser is produced), as shown in fig. 5, a rescuer holds the movable handle 2 to swing up and down, so as to drive the pressing head 1 to forcefully press the chest of a patient, thereby ensuring enough pressing depth and preventing fracture and other complications caused by too large pressing depth.

When in a storage or carrying state, the first section 11 of the pressing swing rod can be pulled out of the jack 14 of the second section 12 of the pressing swing rod, and the first section 11 of the pressing swing rod is rotated about the swing shaft 10 by about 225 degrees, so that the first section 11 of the pressing swing rod is folded with the handheld bracket 4, the first section 11 of the pressing swing rod is stored into the space of the handheld bracket 4, which means that the first section of the pressing swing rod basically does not occupy extra space, and the second section 12 of the pressing swing rod, the floating touch bottom rod 5 and the pressing head 1 can be abutted against the handheld bracket 4 in the storage or carrying state, which means that the transverse width of the whole pressing device in the storage or carrying state is only about half of that in the using state, as shown in fig. 8, the pressing swing rod is very small and convenient to store and carry.

In the first embodiment, the vertical height h of the hand-held bracket 4 may be changed to 42cm, or changed to 20 cm, or changed to 15cm; the transverse span n of the bottom of the hand-held bracket can be changed to 35 cm or 11 cm; the longitudinal span m of the bottom of the hand-held support may be changed to 40cm, or 30cm, or 12cm.

Example two
