fixedlyed connected hermetically specifically can be, the edge of the other end of each body that is tightly connected can have (elasticity) conical contraction mouth, the edge of the other end of each body that is tightly connected is connected by second adhesive tape (adhesive plaster or medical proof fabric or bonding strip), 5 ' patient's corresponding with it the cervical region or the upper limb of hypogastric region or upper limb or surgical staff, promptly at its junction writhing number layer second adhesive tape, thereby realize removably, fixedly connected hermetically.Labelling 7 is patient's the cervical region or the upper limb of hypogastric region or upper limb or surgical staff among Fig. 7, Fig. 8.Certainly, described syndeton is not limited in this kind technical scheme, can also be other technical scheme.As also can second adhesive tape 5 ' the periphery twined the rope 8 of binding effect ' finish closed-loop operation.Each body that is tightly connected is made by nontoxic or medical flexible material, can be made by nontoxic or medical plastic or rubber (making as the material that adopts medical rubber glove), also can be made by other material.It has a plurality of folds, can stretch or shrink, and length can be regulated, and can be corrugated rubber pipe (cover).As mentioned above, the length of each body that is tightly connected can be unequal, and cervical region is shorter by the length that hole, upper limb stretch out the pairing body that respectively is tightly connected in hole by hole, hypogastric region, and the length of the pairing body that respectively is tightly connected of several handle holes is longer.The edge of the other end of each body that is tightly connected (outer end) with (taper shape) contraction mouth played the effect of being convenient to seal.The cross section of each body that is tightly connected can be circle.Can also have the hole (not shown) that the lead that independently connects external monitor and anesthetic machine and other lead pass through on the casing, can adopt adhesive tape to twine the sealing that (perhaps pasting) realizes casing equally.Certainly, the lead of connection external monitor and anesthetic machine and the hole that other lead passes through can also stretch out the hole and enter in the casing along upper limb by above-mentioned upper limb, can adopt adhesive tape to twine the sealing that realizes casing equally, the edge of the other end (outer end) of the body that promptly is tightly connected is connected by second adhesive tape 5 ' patient's corresponding with it upper limb and above-mentioned associated tracks.Certainly, described associated tracks also can be arranged on outside the casing, and the body part outer to casing detects.Casing is installed the back and is formed confined space, and the formation of the interior dynamic negative-pressure of casing (cabin body) relies on the breather of pressure regulator and connection casing and pressure regulator to finish.Simple pressure regulator can have (medical) electric suction apparatus, air inlet adjustment valve, piezometer, and manual control starts and stop the vacuum extractor gas bleeding makes formation negative pressure in the casing, puts gas in conjunction with air inlet adjustment valve open and close and forms dynamic negative-pressure.Complicated and high-grade pressure regulator can be controlled automatically with computer.Electric suction apparatus is originally as prior art.Pressure regulator simulation human body respiratory, it makes by the outside gas bleeding of breather (exhaustor), and negative pressure increases in the casing, and lung tissue is along with expansion, and gas enters lung tissue through trachea and finishes breathing process; The air inlet adjustment valve slowly charges into gas in casing (cabin body) makes in the casing negative pressure lower, and lung tissue withers because of self elastical retraction power, and gas is discharged through bronchus, trachea and finished exhalation process in the lung.Gas bleeding and fill gas body form dynamic negative-pressure.The intravital gas pressure scope of case is observed by manometry, and indication is regulated.The control of simulated respiration frequency adjustable joint.The concrete work process of above-mentioned pressure regulator can be that vacuum extractor continues outwards gas bleeding in the casing, and make casing in formation different negative pressure value reach the effect of a dynamic negative-pressure according to the size of the manometric force value of surveying negative pressure by air inlet adjustment valve regulation (as manual adjustments or Artificial Control) air inflow this moment.Perhaps intermittently outwards gas bleeding in the casing of vacuum extractor, according to the size of the manometric force value of surveying negative pressure by air inlet adjustment valve regulation (as manual adjustments or Artificial Control) air inflow, the air inflow that makes the air inlet adjustment valve and the capacity of vacuum extractor coordinate to reach equally the effect of a dynamic negative-pressure mutually.Perhaps the air inflow of air inlet adjustment valve is constant, makes intermittently outwards gas bleeding in the casing of vacuum extractor according to the manometric force value of surveying negative pressure, reaches the effect of a dynamic negative-pressure equally.When negative pressure value was higher relatively in the casing as described above, lung tissue expanded thereupon, and gas enters lung tissue through trachea and finishes breathing process; Otherwise when negative pressure value was low relatively in the casing, lung tissue withered because of self elastical retraction power, and gas is discharged through bronchus, trachea and finished exhalation process in the lung.
