Abstract
An assistor which can be placed in thoracic cavity only through a simple and minor operation to directly compress cardiac to make resuscitation of heart, consists of compression bag, central locating plate, suspension band and external fixing handle, etc.. Its compression bag is an oblate air bag, and on its surface close to the heart there is an inward concave zone so as to ensure the relative fixation of the heart and compression bag position. When using, the external connection tube of the compression bag is connected with a breathing bag, and the expansion and contraction of the compression bag are made by means of blowing and exhaustion of the breathing bag so as to carry out the cardiac compression and diastole, and its function is identical to that of thoracotomic cardiac compression. Said invention is simple in structure, and is easy to carry about.
Description
The present invention relates to technical field of medical instruments, can put into intrathoracic heart squeezer fast when being a kind of recovery.
At present, clinically the first-selected method for resuscitation of cardiac arrest patient has still been used more than 30 year " routine is closed the breast cardiopulmonary resuscitation " for prolonging, promptly pushed thoracic wall with 80-100 time/minute.Though this method is simple, its effect is unsatisfactory.After heart beating stopped, the cardio-pulmonary resuscitation means must provide the certain blood flow of heart could recover autonomous cardiac rhythm, close the breast cardiopulmonary resuscitation with routine and far do not reach this index.The OCCPR art also is the method for resuscitation that can select for use clinically, opens thoracic wall, pericardium by operation, stretches on the other hand directly extruding heart, and effect is certain.But the thoracotomy wound is big, and time-consuming length will have certain operation technique basis simultaneously, has seriously limited its extensive use, and clinical indication is very narrow.
The cardio-pulmonary resuscitation means effectively with easy, fast have an equal importance, routine is closed the condition that breast cardio-pulmonary resuscitation and OCCPR art all can't possess these two necessity simultaneously.
The objective of the invention is to design a kind of cardio-pulmonary resuscitation appurtenance.Under the prerequisite that does not need conventional thoracotomy, realize direct heart extruding, obtain resuscitation effect and the simple, fast unification of recovery means.
The objective of the invention is to realize by the heart squeezer that design is made of expulsion bladder, centrally-located plate and suspender etc.
Fig. 1 is a breastbone face front view of the present invention, there is shown centrally-located plate (1), expulsion bladder breastbone face (2), extension tube attached (3) and external fixation handle (4).
Fig. 2 is a surface of heart front view of the present invention, there is shown expulsion bladder central authorities indent district (5) and outer ridge (6).
Fig. 3 is the side view of expulsion bladder of the present invention before sufficient gas, there is shown to be used to keep the indent district ⑸ of surface of heart central authorities still has certain concavity after inflation suspender (7).
Fig. 4 is the side view behind the expulsion bladder sufficient gas of the present invention, has reflected the effect of suspender.
Now the invention will be further described by reference to the accompanying drawings.
Main body of the present invention is expulsion bladder, is oblate air bag, and the flexible materials nontoxic to body and that tension force is high such as available silica gel, latex or poly-ethamine are made, and external diameter is slightly larger than heart, and about 80-140mm, wall thickness should be enough to resist the 300mmHg intracapsular pressure; Its breastbone face (2) is the plane or is spherical surface hill, and its surface of heart then consists of the concave surface that matches with heart by the relative outstanding outer ridge (6) with the outside in central indent district (5). The concavity of expulsion bladder surface of heart is fixed in the suspender (7) that centrally-located plate (1), the other end be fixed in central indent district (5) by an end and maintains after the inflation. Take this, can be limited to heart on the direction of extrusion of expulsion bladder during recovery, guarantee squeezing effect. The available silica gel elastomeric material of suspender (7) is made. Expulsion bladder communicates with external respiratory hag through its peripheral extension tube attached (3). Centrally-located plate (1) is rectangular flat board, and part links to each other with breastbone face (2) in the capsule; Be the groove shape after stretching out extension tube attached, so that ventilation and fixing is renamed as outer fixed handle (4). Centrally-located plate (1) and the available stainless steel of outer fixed handle (4) or other hard materials are made. Extension tube attached (3) outer end and respiratory hag join, and by the hypertonic of respiratory hag to the inflation of expulsion bladder and exhaust control expulsion bladder, thereby heart are played the effect of compressing and diastole.
During clinical practice, in advance gas in the expulsion bladder is discharged, cyst wall surrounds on the centrally-located plate, so that insert the thoracic cavity by little otch.Be about the 50mm otch to peritoneum down in xiphoid-process, enter the about 120mm of pericardium anterior diastema through diaphram.After squeezer inserted this gap, with external breathing bag it is blown and to open, expulsion bladder is covered on the heart, adjusted by external fixation handle (4) again and fix, guarantee the position relative fixed of expulsion bladder and heart in the recovery process.So far, external breathing bag just can drive the hypertonic of expulsion bladder, implements compressing and diastole to heart.Recovery is withdrawed from squeezer, sew up wound after finishing.
The inventor recommends following embodiment:
Expulsion bladder is made with silica gel, and it is outstanding that the about 80-140mm of oblate air bag external diameter, breastbone face (2) are sphere, the about 150mm of radius of the radian; The about 40mm of surface of heart central authorities' indent district (5) diameter, suspender (7) is made with silica gel, is about 45mm under the relaxation state, wide about 15mm, the about 14mm of extension tube attached (3) internal diameter, the about 18mm of external diameter.Centrally-located plate (1) and external fixation handle (4) are made with rustless steel, the wide about 15mm of centrally-located plate (1).Thick about 0.5mm, the external fixation handle is the groove shape, is about 150mm.Squeezer can be surrounded at ordinary times on the centrally-located plate (1), the packing sterilization is with emergency.
The present invention is simple in structure, and is easy to make, cheap, is easy to carry.Surgical apparatus is common, and is easy and simple to handle quick, thereby for rescuing the time of having won.Its operation wound is little, opens the extruding of the direct heart of breast but effect is similar, also can keep somewhere in the body, up to stable circulation in case of necessity.Therefore, the present invention has realized that substantially the recovery means are fast with effectively unified.
