Description
This utility model is a kind of External heart pump that is used for cardio-pulmonary resuscitation and assisted respiartion treatment.
Rescue heart beating, respiratory arrest clinically prolongs with traditional free-hand closed cardiac massage extruding more.In recent years, the external cardiac compression machine has been used for clinical, owing to its row malleation, extruding heart, therefore following defective is arranged: the one, can cause some patient, especially elderly patients' fracture of rib; The 2nd, it is bad that thorax is replied, and causes the intrathoracic negative pressure forfeiture, thereby the diastole and the blood that have hindered heart reflux, and also are unfavorable for setting up effective blood circulation; The 3rd, be not suitable for auxiliary coma patient or the paralysis of respiratory muscle disease patient's that causes because of nervous system disease respiratory therapy.
The purpose of this utility model is to overcome above-mentioned defective, and a kind of External heart pump that integrates extruding heart, assisted respiartion function is provided, and it can promote diastole and blood to reflux, and is beneficial to gas exchange, makes cardio-pulmonary resuscitation approach person's physiological processes.
The purpose of this utility model is achieved in that and is provided with caulking gum lining and rubber chamber circle that it is respectively attached on the inwall of gas tank and the uncovered edge; Be provided with air bag, be positioned at the gas tank intracavity; Be provided with breather, the one end is communicated with high-pressure pump, and the other end passes the QI KOU of gas tank wall and rubber lining back communicated air bags; Be provided with pneumatic indicator and options button, they and selector switch are loaded in the groove of outside, gas tank bottom.
This utility model is used for the cardio-pulmonary resuscitation process and has following major advantage:
One, reasonable in design can satisfy the requirement of cardio-pulmonary resuscitation near person's physiological processes.
Two, easy to operate, as can to provide according to display information is pressed options button, and promptly the air pressure in scalable air bag and the gas tank makes the patient be in the good curing state.
Three, function is many: both can be by to the inflation of air bag or bleed, make air bag form malleation, extruding heart, or make the gas tank intracavity form negative pressure, expansion thorax, to promote diastole and blood to reflux, also can be by R ripple triggering synchronous extruding heart, and the promotion diastole, to be used for the auxiliary treatment of severe congestive heart failure.In addition, also can be used for the paralysis of respiratory muscle that a variety of causes causes, make auxiliary treatment.
Its four, safe in utilization, it is bad that patient's fracture of rib and thorax are replied.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the upward view of Fig. 1.
Fig. 4 is the perspective view of Fig. 1.
Structure of the present utility model such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: be provided with caulking gum lining 1 and rubber ring 2, the former is with on the inwall all around of adhesion mode attached to gas tank 4; The latter connects on the uncovered edge of mode attached to gas tank with adhesion or embedding, and when embedding connected, uncovered edge stretched in the groove of rubber ring, and uncovered outer likeness in form " saddle " shape seals so that the gas tank chamber touch thoracic wall.Be provided with air bag 3, can adopt silicone rubber to make, profile is spheroid shape or other kind shape, is positioned at the gas tank intracavity.Be provided with the breather 5 that flexible steel moulding material or other kind material are made, the one end passes the gas tank wall and rubber lining back is communicated with the air bag QI KOU, and the other end is communicated with high-pressure pump 6.Be provided with pneumatic indicator 9, ECG R wave triggering selection switch 10 and options button 11, they are contained in the groove of outside, gas tank bottom.
The shell of above-mentioned gas tank (casing), can adopt light materials such as aluminium alloy, sheet plastic to make, have fixed and two kinds of casings of force-loose: former structure is simple, makes easily, but make the large and small series of products that do not wait, the requirement that different build patients such as, size fat or thin to adapt to use; The latter is just the opposite, and promptly structure is complicated, be not easy to make, but the patient of the applicable different builds of a machine.The structure of force-loose casing is: its sidepiece is made of some blocks of boxboards of folding formula rubber connector (connecting forward and backward compartment box part in the similar long bus) serial connection, between its bottom and the tank wall annular hinges is housed; Like this, it can suitably regulate the size in gas tank chamber automatically according to patient thoracic cavity size.Hinges can be formed (see figure 3) by metal (or other rigidity material) circle 7 and several loose-leaves 8 that are movably connected with it, and wherein, outer ring loose-leaf and gas tank tank wall are connected (weldering company), inner ring loose-leaf and gas tank bottom surface be connected (company of weldering).
Above-mentioned pneumatic indicator can be made up of negative pressure display in malleation display, the gas tank in LCDs and the air bag, and it links to each other with the contact of selector switch 10 with options button 11 by lead.Options button has 3, is respectively positive and negative pressure options button and R wave frequency options button, and itself and selector switch all can adopt the structure of touch depression key and be contained on the bearing 12, and bearing is arranged in the groove of outside, gas tank bottom.
Brief description work process of the present utility model once.
During application, earlier gas tank 4 is buckled between patient's the breastbone stage casing and umbilicus, makes sealing rubber ring 2 be close to patient's thoracic wall,, make 3 inflations of 6 pairs of air bags of high-pressure pump or bleed again by the effect of the positive and negative pressure options button in the options button 11; After the inflation, utilize malleation extruding heart in the air bag; After bleeding, the airtight effect because of rubber ring and rubber lining 1 makes the gas tank intracavity form negative pressure, both can make thoracic expansion by negative pressure, diaphragm is moved down, to increase negative pressure in the thoracic cavity, help promoting blood backflow heart and ventricular diastole, be beneficial to the purpose of cardio-pulmonary resuscitation.
If operating selection switch 10 and R wave frequency options button can utilize R ripple triggering synchronous extruding heart, and promote diastole again, be used for the assisted respiartion treatment of severe congestive heart failure or paralysis of respiratory muscle.
