Abstract

A cricothyrotomy syringe has a hollow body, a needle connector at an end of the body, an aperture at an opposite end of the body, a plunger in the aperture, the plunger having a seal that forms a liquid tight seal with an inner surface of the body and the plunger moveable within the body between an extended position and a compressed position and a ventilator adaptor extending from a side of the body, where an interior of the ventilator adaptor is in fluid communication with an interior of the body when the plunger is in the extended position.

Claims

1. A medical device for establishing an airway, comprising:

a syringe comprising a hollow body;

a needle connector at an end of the body;

an aperture at an opposite end of the body;

a plunger in the aperture, the plunger having a seal that forms a liquid tight seal with an inner surface of the body, the plunger being moveable within the body between a first position and a second position; and

a ventilator adaptor extending from a side of the body,

wherein, when the plunger is in the second position, the seal of the plunger is disposed between the ventilator adaptor and the needle connector such that the seal limits fluid communication between an interior of the ventilator adaptor and an interior of the body; and

wherein the ventilator adaptor is disposed between the seal of the plunger and the needle connector when the plunger is in the first position such that the interior of the ventilator adaptor is in fluid communication with interior of the body when the plunger is in the first position.

2. The device of claim 1, wherein the ventilator adaptor is closer to the aperture than to the needle connector.

3. The device of claim 2, wherein the ventilator adaptor is in an upper one-third of the body.

4. The device of claim 1, wherein the ventilator adaptor sized to receive a 3.0 mm inner diameter endotracheal tube.

5. The device of claim 1, wherein the ventilator adaptor sized to receive a 2.5 mm inner diameter endotracheal tube.

6. The device of claim 1, wherein the ventilator adaptor sized to receive a 2.0 mm inner diameter endotracheal tube.

7. The device of claim 1, further comprising a cap on the ventilator adaptor.

8. The device of claim 1, wherein the ventilator adaptor is at about a 45°

angle to a main axis of the body.

9. The device of claim 1, wherein the ventilator adaptor is between about a 30°

and 90°

angle to a main axis of the body.

10. The device of claim 1, wherein the ventilator adaptor has a tapered portion.

11. The device of claim 1, wherein the needle connector is a luer lock connector.

12. The device of claim 1, wherein a portion of the ventilator adaptor closest to the body is formed of a rigid material.

13. The device of claim 1, further comprising a flange surrounding the aperture.

14. The device of claim 1, wherein the body is capable of holding 5 cc of fluid.

15. The device of claim 1, wherein the body is formed of plastic.

16. The device of claim 1, wherein the body is a right cylinder.

17. The device of claim 1, further comprising a valve between the hollow body and the needle connector.

18. The device of claim 17, wherein the valve is a three way valve.

19. The device of claim 1, further comprising a needle connected to the body at the needle connector.

20. A method of using the device of claim 19, comprising:

inserting the needle into a trachea of a patient with a blocked airway, wherein the syringe is filled with a liquid;

pulling the plunger toward the first position;

determining whether bubbles appear in the liquid;

if bubbles appear in the liquid, expelling the liquid from the syringe;

after expelling the liquid from the syringe, pulling the plunger toward the first position to place the interior of the ventilator adaptor in fluid communication with an interior of the needle; and

after determining that bubbles appear in the liquid, attaching a ventilator device to the ventilator adaptor.

21. A kit, comprising:

the device of claim 1; and

one or more of a blade, a French flexible suction catheter, disinfectant, sutures, a disposable bipolar electrosurgical handpiece, a disposable unipolar electrosurgical handpiece, electrosurgical tip cleaner, a spatula, a needle, pack peanuts, a syringe or a solution of lidocaine with epinephrine.
