Abstract

The utility model relates to a puncture needle for ring membrane used as an emergency equipment for the respiratory tract obstruction. The utility model is composed of an arc-shaped needle tube (1), and a needle core (2) inserted into the arc-shaped needle tube (1) and matching with the arc-shaped needle tube (1). The arc-shaped needle tube (1) and the needle core (2) are made of hard material, and a plurality of ventholes are arranged at the outer wall of the arc-shaped needle tube (1). The puncture needle for ring membrane is used to rescue the patients of respiratory tract obstruction, with the ability of feeding oxygen, and inhaling phlegm at the same time, breathing and feeding oxygen at the same time, or breathing and inhaling phlegm at the same time, having the advantage of convenient and safe utilization.

Description

A kind of cricothyroid membrane puncture needle

This utility model relates to the survival kit behind a kind of respiratory tract obstruction.

In the past, for a certain reason, patient's respiratory tract obstruction is in the time can not breathing, the method of first aid normally adopts a kind of straight tube to be needled into ring first film, and an end is stayed in the trachea, and the other end is outside trachea, the patient respiration road is communicated with the external world, solve the anoxia problem, thereby, a chance that gives emergency treatment to a patient created.Adopt this straight tube pin straight thrust to pierce into ring first film, following shortcoming arranged:

1, because people's trachea and food meatus are close together, when using straight tube pin puncture ring first film, generally is, damages the esophagus antetheca when thrusting straightly so easily from the front straight thrust;

2, owing to will pass ring first film, so straight type needle tubing can not be too thick, therefore, ventilation just is restricted, and often can not satisfy patient's needs;

3, after straight tube is needled into ring first film, at one time in, can't realize functions such as breathing, oxygen supply and suction expectorant.

The purpose of this utility model provides a kind of shortcoming that overcomes the straight tube pin, can realize breathing, oxygen supply simultaneously or inhale two functions of expectorant, novel cricothyroid membrane puncture needle esy to use, safe and reliable.

This utility model is achieved in that as shown in Figure 1, is made up of the nook closing member 2 that also matches with it in arcual needle tubing 1 and the insertion needle tubing 1.The afterbody of nook closing member 2 can pass in nook closing member 1 pipe and penetrate, and needle tubing 1 and nook closing member 2 are made by hard materials such as ferroalloy, aluminium alloy or plastics.Needle tubing 1 be processed into the front end outer diameter less than the rear end outer diameter (part of at first thrusting trachea is a front end, after enter trachea part be the rear end), have several garden shape passages on the needle tubing 1 outer arcuate tube wall, as shown in Figures 2 and 3.The front end of nook closing member 2 is inequilateral prismatic needle points, and as shown in Figure 4, the diameter in the external garden (as shown in Figure 5) of needle point largest portion and the outer tube diameter of needle tubing 1 front end equate.

Use step of the present utility model (being example) as follows to cross:

1, the right hand is held needle holder, clamp the rear portion of cricothyroid membrane puncture needle with needle holder, left hand is determined the position of ring first film, needle point is thrust its ring first film by the patient left side, make the front end of needle point and needle tubing 1 encircle first film right side and pass, and keep the rear end part of needle tubing 1 to be exposed at patient encircling the outer left side of first film by patient;

2, the afterbody of nook closing member 2 is pushed in the needle tubing 1;

3, clamp the needle point and the backshank intersection of nook closing member 2 with needle holder, nook closing member 2 is extracted;

4, last, utilize and expose the two ends that patient encircles the needle tubing 1 of first film outside, inhale expectorant, operations such as oxygen supply.

Fig. 6 is the sketch map that is horizontally through ring first film.

Vertically pass ring first film if adopt, its method is identical with said method, and Fig. 7 is the sketch map that vertically puncture encircles the first film.

Adopt this utility model than adopting straight tube shape puncture needle, following advantage arranged:

1, because this utility model is a camber, be to thrust and pass ring first film from the side during operation, the shortcoming of easy damaged esophagus antetheca in the time of can avoiding thrusting straightly ring first film;

2, because this utility model is an arc, operational approach can adopt crosses thorn and indulges two kinds of punctures, more nimble, safety;

3, owing to have several holes, garden on the tube wall of this puncture needle middle part, leave the gross area in hole, endotracheal tube wall garden, much larger than the area of two termination pores, the arc puncture needle is compared under the condition of equal diameters with straight shape pin, and the area of its air inlet/outlet has increased by one times;

During 4, owing to usefulness arc lancet puncture ring first film first-aid patients, the puncture needle two ends are stayed outside the patient body, therefore, can realize an end respiratory gas, and the other end is inhaled expectorant; When inhaling expectorant like this, inhale expectorant when having avoided and cause negative pressure in the trachea, and make the shortcoming of inhaling the expectorant difficulty with the straight tube puncture needle;

5, because arc puncture needle two ends are stayed outside the patient body, can realize an end oxygen supply, other end breathe air has been avoided employing straight tube pin when puncture, causes partial pressure of oxygen too high and produce the shortcoming of oxygen intoxication to oxygen excess;

6, because arc puncture needle two ends are stayed outside the patient body, when patient's anoxia, can realize inhaling expectorant and oxygen supply simultaneously.

Most preferred embodiment of the present utility model as shown in Figure 1, needle tubing 1 front end external diameter is 2.6 millimeters, the rear end external diameter is 3.2 millimeters, internal diameter is 2 millimeters, chord length is 60 millimeters.Have 12 diameters on the curved pipe lateral wall and be 1.5 millimeters hole, garden.Nook closing member 2 tail diameter are 1.5 millimeters, and needle core tip length is 6 millimeters, and the diameter in the external garden of needle core tip inequilateral prismatic is 2.6 millimeters.Needle tubing 1 and nook closing member 2 are made by rustless steel.With this arc cricothyroid membrane puncture needle, carry out the many cases patient and try out, conform with the requirement for the treatment of patient fully, be subjected to medical worker's welcome deeply.
