Trachea puncture positioning device

Abstract

A trachea puncture positioning device comprises a tube body, scales are arranged on the outer surface of the tube body, an operating rod is fixed to the head end of the tube body, a tube cavity is formed in the tube body, the tube cavity extends to the tail end of the tube body from the head end of the tube body in the axial direction of the tube body and then is bent to form a 90-degree arc angle, an indicating hole is formed in the radial direction, and an indicating device is arranged in the tube cavity. The indicating device comprises a traction guide wire, the traction guide wire and the tube body form a sliding pair parallel to the extending direction of the tube cavity, and an indicating lamp is fixed to one end of the traction guide wire. The traction guide wire is used for controlling the laser lamp to move, when the laser lamp moves to the arc angle, the laser lamp is bent due to the influence of the arc angle, the irradiation direction of the laser lamp is perpendicular to the body surface, and therefore light beams of the laser lamp are perpendicular to the body surface to be emitted outwards and positioned to the tail end of the tracheal catheter. Medical staff can see the positioning point on the body surface and perform aligned puncture, so that an air bag and a tube wall of the tracheal catheter can be prevented from being punctured, and the puncture success rate is increased.

Description

Technical Field

[0001] The utility model relates to daily necessities for human beings, in particular to medical equipment, and more particularly to a tracheal puncture positioning device. Background Art

[0002] Endotracheal intubation involves inserting a specialized endotracheal tube into the trachea or bronchus, providing optimal conditions for airway patency, ventilation, oxygenation, and suctioning. After intubation, medical personnel must puncture the distal end of the endotracheal tube, avoiding the balloon and tube wall. However, existing techniques lack the ability to locate the puncture point, making it difficult to align the endotracheal tube tip during puncture, creating a risk of puncturing the balloon and tube wall. Summary of the Invention

[0003] The purpose of the utility model is to provide a tracheal puncture positioning device, which is intended to solve the technical problem in the prior art that the puncture point cannot be positioned, resulting in difficulty in aligning the end of the tracheal tube during puncture.

[0004] The utility model provides a tracheal puncture positioning device, including a tube body, the outer surface of the tube body is provided with a scale along its length direction, an operating rod is fixed to the head end of the tube body, a tube cavity is provided in the tube body, the tube cavity extends from the head end of the tube body along the axial direction of the tube body to the tail end of the tube body and then bends to form an arc angle of 90°, and then an indicator hole is opened in the radial direction on the side wall of the tube body, an indicator device is provided in the tube cavity, the indicator device includes a traction guide wire, the traction guide wire and the tube body form a sliding pair parallel to the extension direction of the tube cavity, an indicator light is fixed to one end of the traction guide wire, the other end of the traction guide wire passes through the operating rod and extends outward, and a through hole for the traction guide wire to pass through is provided in the operating rod.

[0005] Furthermore, the indicator light is a laser lamp.

[0006] Compared with the existing technology, the present invention has a positive and obvious effect. The tracheal puncture positioning device is placed in the tracheal tube, and the depth of the tube body in the tracheal tube is observed according to the scale outside the tube body to confirm that the tube body and the end of the tracheal tube are at the same depth. Then, a traction guide wire is used to control the movement of the laser light. When the laser light moves to the arc angle, it bends under the influence of the arc angle, making the irradiation direction of the laser light perpendicular to the body surface, so that the laser light beam is emitted perpendicular to the body surface and positioned at the end of the tracheal tube. Medical staff can see the positioning point on the body surface and perform alignment puncture, thereby avoiding puncturing the air bag and tube wall of the tracheal tube and improving the success rate of puncture.

[0009] The following is a further description of the present invention in conjunction with an embodiment. However, the present invention is not limited to the embodiment. All similar structures and similar variations of the present invention should be included in the scope of protection of the present invention. The use of directions such as up, down, front, back, left, and right in the present invention is only for the convenience of clear description and does not limit the technical solution of the present invention.

[0010] like Figure 1 and Figure 2 As shown, a tracheal puncture positioning device of the present invention includes a tube body 2, the outer surface of the tube body 2 is provided with a scale 4 along its length direction, an operating rod 1 is fixed to the head end of the tube body 2, a tube cavity 3 is provided in the tube body 2, the tube cavity 3 extends from the head end of the tube body 2 along the axial direction of the tube body 2 to the tail end of the tube body 2 and then bends to form a 90° arc angle 4, and then an indicator hole 5 is opened in the radial direction of the side wall of the tube body 2, an indicator device 6 is provided in the tube cavity 3, the indicator device 6 includes a traction guide wire 61, the traction guide wire 61 and the tube body 2 form a sliding pair parallel to the extension direction of the tube cavity 3, an indicator light 62 is fixed to one end of the traction guide wire 61, the other end of the traction guide wire 61 passes through the operating rod 1 and extends outward, and the operating rod 1 is provided with a through hole for the traction guide wire 61 to pass through.

[0011] Furthermore, the indicator light 62 is a laser lamp.

[0012] Specifically, the traction guide wire 61 , the indicator light 62 , the laser lamp, etc. in this embodiment all adopt well-known solutions in the prior art, which are well understood by those skilled in the art and will not be described in detail here.

[0013] The working principle of this embodiment is as follows:

[0014] The scale 4 on the surface of the tube body 2 is adapted to the size of the endotracheal tube. During use, the endotracheal puncture positioning device is placed into the endotracheal tube. The depth of the tube body 2 within the endotracheal tube is observed based on the scale 4 on the outside of the tube body 2 to confirm that the tube body 2 and the distal end of the endotracheal tube are at the same depth. The guide wire 61 is then used to control the movement of the laser light. When the laser light moves to the arc angle 4, it is affected by the arc angle 4 and bends, making the irradiation direction of the laser light perpendicular to the body surface. This allows the laser light beam to be emitted perpendicularly to the body surface and locate the distal end of the endotracheal tube. Medical personnel can see the positioning point on the body surface and perform alignment puncture, thereby avoiding puncturing the balloon and tube wall of the endotracheal tube and improving the success rate of puncture.

[0015] The lumen 3 of the present invention is provided with a 90-degree arc angle 4, which facilitates the angle adjustment of the laser lamp in the lumen 3 so that the laser lamp is emitted vertically from the body surface. In order to be able to observe the relative position depth of the tube body 2 and the endotracheal tube and judge the depth of the tube body 2, a scale 4 adapted to the size of the endotracheal tube is opened on the surface of the tube body 2, thereby meeting the requirements of observing the depth of the tube body 2 in the endotracheal tube and confirming that the tube body 2 and the end of the endotracheal tube are at the same depth.
