Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the present embodiment discloses a percutaneous tracheal puncture device, comprising a puncture needle 1, a connecting tube 2 and an adaptor 3, wherein the puncture needle 1 comprises a needle body 11 and a needle tube 12 sleeved on the periphery of the needle body 11, the end of the needle tube 12 is provided with a connecting part 121, and specifically, the connecting part 121 is a tapered hole; one end of the connecting pipe 2 is provided with a joint 21 communicated with the inside of the connecting pipe 2, the periphery of the joint 21 is a conical surface matched with the connecting part 121, and the other end of the connecting pipe 2 is connected with the adaptor 3; adaptor 3 is L shape, including first switching portion 31 and the second switching portion 32 that mutually perpendicular connects, first switching portion 31 and second switching portion 32 are hollow structure, the tip of keeping away from each other at first switching portion 31 and second switching portion 32 forms first interface and second interface respectively, wherein, the one end that first switching portion 31 was kept away from to second switching portion 32 is pegged graft in connecting pipe 2, adaptor 3 communicates through the inside of second interface and connecting pipe 2.

The method of using the percutaneous tracheal puncture device of the embodiment is as follows: the patient lies on the face upward, the head is bent backwards to be over-extended by a pad under the neck shoulder, a puncture point is selected between 2-3 tracheal cartilage rings, the puncture needle 1 is slightly inclined towards the head, the needle is inserted until the head is empty, the needle body 11 is pulled out to keep the needle tube 12 in the original position, the needle tube 12 is connected after the syringe pumps half-tube physiological saline, air bubbles are sucked out when the syringe pumps half-tube physiological saline, the needle tube 12 can be clearly kept in the trachea again, the connecting tube 2 is installed after the syringe is removed, the first interface of the adapter piece 3 is connected with a respirator or a breathing air bag for mechanical or manual ventilation, and if the trachea is subsequently cut, a guide wire can be directly placed in through the needle tube 12 without making an operation incision, and then the trachea is placed for guiding.

When a patient is in danger of asphyxia and has upper respiratory tract obstruction in an emergency, and intubation fails or tracheotomy cannot be safely carried out or cannot be carried out in time, the percutaneous tracheal puncturing device can relieve the obstruction of the airway; in addition, when the infants and the old people are blocked by foreign matters in the air passages and the treatment by a non-invasive method (such as a Helmhick first aid method) is ineffective, 120 or emergency workers can take first aid by the percutaneous air tube puncture device of the embodiment. Therefore, the percutaneous trachea puncture device can quickly establish an artificial airway in emergency, save the life of a patient, can be used as a 'lifesaving' tool on anesthesia, emergency treatment, an ICU and an ambulance, and can complete subsequent treatment such as 'tracheotomy' and the like on the basis of the emergency.

Furthermore, a convex column 311 is arranged outside the first adapter 31, a through hole communicated with the inside of the adapter 3 is arranged on the convex column 311, a cover body 33 is connected to the outer circumference of the convex column 311 in a threaded manner, when secretion exists in the respiratory tract of the patient, the cover body 33 can be unscrewed, and the sputum suction device is placed in the sputum suction device to suck sputum.

In this embodiment, the puncture needle 1 is a common conical tracheal puncture needle, and a standard conical hole 6:100 is provided at the end of the needle tube 12, and can be connected with the nipple of a standard syringe, and the conical hole is the connection part 121; the connecting tube 2 is a 20 ml empty tube of a disposable syringe, the nipple of the syringe is the joint 21, and can be connected with a standard taper hole of the needle tube, and the nipple is provided with a thread, so that the connection with the needle tube 12 is more stable.
