Specific implementation mode

The utility model is described in detail in each embodiment shown in below in conjunction with the accompanying drawings, but it should explanation, These embodiments are not limitation of the utility model, and those of ordinary skill in the art are according to work(made by these embodiments Energy, method or the equivalent transformation in structure or replacement, belong within the scope of protection of the utility model.

A kind of cricothyroid membrane puncture needle component as shown in figures 1 to 6, including remaining needle 11, are stayed with what remaining needle 11 was connected Sleeve 1, the needle core being placed in remaining needle 11 31 are set, is connected with needle core 31 and is located at needle core base 3, the ring cloth in indwelling sleeve 1 Air bag 6 on 11 internal face 110 of remaining needle and the gas injection cylinder 4 for being connected and being carried out to air bag 6 inflation/deflation with air bag 6.

6 side of air bag and 11 internal face of remaining needle, 110 bonding fixation, air bag 6 are located at 11 internal face 110 of remaining needle and needle Between 31 outside wall surface of core, air bag 6 is synchronized along 11 extending direction of remaining needle to be extended, and needle core 31 is synchronized along 11 extending direction of remaining needle to be prolonged It stretches and the needle tip of needle core 31 extends outside remaining needle 11.

The propelling piece 41 that gas injection cylinder 4 includes cylinder 42 and is partly placed in cylinder 42, propelling piece 41 is in cylinder 42 It moves downward to be inflated for air bag 6, propelling piece 41 moves upwards to deflate for air bag 6 in cylinder 42.Gas injection cylinder 4 is located at Outside remaining needle 11, cylinder 42 is connected to by air injection pipe 62 with air injection opening 61, and air injection opening 61 is connected to air bag 6.

By the ring cloth air bag 6 on 11 internal face 110 of remaining needle and it is inflated, on the one hand, in thyrocricocentesis When needle is inserted into patient, by air bag 6, closely pressure holding makes needle core 31 to needle core 31 to make needle core 31 be firmly fixed in remaining needle 11 An entirety is formed with remaining needle 11, improves the accuracy of cricothyroid membrane puncture needle insertion；On the other hand, it is pulled out from remaining needle 11 When going out needle core 31, since air bag 6 has the function of damping, the vibration amplitude extracted and generated when needle core 31 can be reduced as possible, is prevented At remaining needle 11 position offset occurs for major structure to cause to threaten patient health for hypoxgia, improves cricothyroid membrane puncture needle group The safety coefficient that part uses.

After needle core 31 is removed, propelling piece 41 is moved upwards in cylinder 42 to deflate for air bag 6, finally makes oxygen It is input in patient airway by remaining needle 11.

The indwelling sleeve 1 is equipped with the Liang Ge ears 5 being symmetric, and binding rope 51 can be each passed through Liang Ge ears 5, Binding rope 51 is tied up into patient's neck again, to play the role of fixed cricothyroid membrane puncture needle component.

Indwelling sleeve 1 is formed with through-hole 10,1 both ends open of indwelling sleeve, and one end is connected to remaining needle 11, the other end with Ventilating joint 2 is connected.

Ventilating joint 2 is fixed with indwelling sleeve 1 by 120 phase of connector, and ventilating joint 2 is formed with through-hole 20 and its both ends Opening, the ventilating joint 2 is equipped with external screw thread 21 or internal thread 22 far from 1 end of indwelling sleeve, it is of course also possible in ventilating joint 2 are arranged external screw thread 21 and internal thread 22 simultaneously far from 1 end of indwelling sleeve.It is ring first by the way that external screw thread 21 and internal thread 22 is arranged Membrane puncture needle component and the connection of lung ventilator (not shown) provide two kinds of connection types, shorten cricothyroid membrane puncture needle group The docking time of part and lung ventilator improves safety coefficient and flexibility that cricothyroid membrane puncture needle is used with component.

Connector 120 is by being arranged 2 internal face 26 of the elastic bumps 14 in 1 outside wall surface 16 of indwelling sleeve and ventilating joint On recessed portion 24 form, circular in cross-section, sector or the rectangle of elastic bumps 14 and recessed portion 24, and preferably fan Shape, elastic bumps 14 are made of elastic material such as rubber.When using cricothyroid membrane puncture needle component, it is only necessary to by recessed portion 24 are held in the rapid abutting joint that indwelling sleeve 1 and ventilating joint 2 can be realized on elastic bumps 14, shorten and carry out oxygen for patient The front and continued time of gas supply.The ventilating joint 2 is equipped with to recessed portion 24 and extends internally fin 23, and the elasticity is convex 14 containers 13 for being equipped with receiving fin 23 are played, to further improve the combination jail of ventilating joint 2 and indwelling sleeve 1 Degree.

Remaining needle 11 has the crooked radian size of certain crooked radian and the two identical with needle core 31, to make indwelling What needle 11 can more be stablized is nested in outside needle core 31.The crooked radian of remaining needle 11 and needle core 31 is 0.5-1rad, and will Remaining needle 11 and the crooked radian of needle core 31 are both preferably 0.6rad, to make remaining needle 11 and needle core 31 be inserted into patient airway When can be somewhat downwardly flexed, situations such as avoiding injured patient's blood vessel or inserting needle too deep accidental injury oesophagus, occurs, and improves ring first The safety that membrane puncture needle is used with component.

The occupation mode of the cricothyroid membrane puncture needle component is as follows：Needle core 31 is placed in remaining needle 11, gas injection cylinder 4 is passed through Air bag 6 is inflated, cricothyroid membrane puncture needle is inserted into patient airway, has air-flow sense then to indicate to be inserted into successfully.Extract needle core 31, it is deflated by 4 pairs of air bags 6 of gas injection cylinder, ventilating joint 2 is connected to lung ventilator, then by ventilating joint 2 and indwelling sleeve 1 Connection.Oxygen passes sequentially through through-hole 20, through-hole 10 and remaining needle 11 subsequently into patient airway.

Tool of the series of detailed descriptions listed above only for the feasible embodiment of the utility model Body illustrates that they are all without departing from made by the utility model skill spirit not to limit the scope of protection of the utility model Equivalent implementations or change should be included within the scope of protection of this utility model.

In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art The other embodiment being appreciated that.
