Abstract

The present invention provides a tracheostomy tube guide device, which is partially inserted into an external tracheostomy tube so that an operator can monitor the inside of a living trachea in the neck of a living body. The tracheostomy tube guide device includes a grip, a camera tube and a camera. The grip contains a storage battery and a wireless image transmitting module. The camera tube is inserted into the external tracheostomy tube until the camera passes through the end of the tracheostomy tube to observe the inside of the living trachea. Then, when the tracheostomy tube penetrates the neck of the living body into the living trachea, the inside of the living trachea is imaged by the camera and then transmitted to the operator by the wireless image transmitting module. The operator observes the image of the displacement of the part of the tracheostomy tube in the living trachea until the part of the tracheostomy tube is well positioned in the living trachea.

Description

Tracheostomy tube guide device

The present invention relates to a guiding device, in particular to a tracheotomy tube guiding device for viewing live tracheal images.

With the advancement of medical technology, patients with respiratory failure can use ventilators or portable oxygen supply equipment to provide patients with sufficient tissue oxygen supply. However, before using these devices, it is very important to maintain an effective and safe airway. Therefore, for patients who need long-term use of respiratory assistance devices, tracheotomy and tracheostomy tube implantation are necessary.

There are two main ways to perform tracheotomy today: one is a traditional surgical procedure where the patient is under general anesthesia and the surgeon cuts a small hole between the first, second, third, or fourth tracheal cartilage in the neck and inserts a tracheostomy tube to help the patient breathe. Tracheotomy first involves marking the position of the thyroid cartilage and cricoid cartilage, marking the position where the tracheostomy tube can be placed, and then using a blade to cut horizontally at the marked position, with a cutting length of about 1.5 cm to 2 cm. Afterwards, a guide wire is used to penetrate into the living trachea, and the tracheostomy tube is mostly installed in the living trachea through the guidance of the guide wire to provide the patient with smooth breathing, and to extract foreign matter (such as sputum) in the patient's respiratory tract. The other is percutaneous tracheotomy, which is performed under the guidance of a tracheoscope. Due to the operator's lack of skill, nervousness, or too small an incision, the puncture may be too deep and damage or rupture the tracheal wall, injure the esophagus, or even injure a fatal artery.

In view of the above-mentioned deficiencies in the prior art, the inventor has studied ways to improve these deficiencies, and finally came up with the present invention.

In view of this, one of the purposes of the present invention is to propose an imaging tracheostomy device and a tracheostomy tube guide device. By performing percutaneous tracheotomy, an image sensor (CMOS Sensor) is directly placed at the front end of the tracheostomy tube in the respiratory tract to replace the tracheoscope. The image is directly confirmed at the front to assist the operator in observing whether the tracheostomy tube is inserted too deep into the living trachea, so as to solve the problem of puncturing too deeply and injuring the bottom wall of the trachea, the esophagus, or the artery.

To achieve the above-mentioned purpose, a tracheostomy tube guide device according to the present invention is partially inserted into an external tracheostomy tube so that an operator can monitor the inside of the living trachea of the living body's neck. The tracheostomy tube guide device includes a grip, a camera tube and a camera. The grip is cylindrical and has a storage battery and a wireless image transmitting module in the grip. The camera tube is connected to the grip, and the camera is connected to the camera tube. The camera has an image sensing element and a lens. The lens is located in front of the image sensing element. The head end of the camera tube is connected to the grip, and the tail end of the camera tube is connected to the camera. This camera catheter is inserted into the external tracheostomy tube until the camera passes through the end of the tracheostomy tube to observe the inside of the living trachea. Then, when the tracheostomy tube passes through the neck of the living body and into the living trachea, the inside of the living trachea is imaged through this camera and then transmitted to the operator using this wireless image transmission module. The operator observes the image of the displacement of part of the tracheostomy tube in the living trachea until part of the tracheostomy tube is positioned in the living trachea.

The lens is covered with a condom, which is disposable or sterilizable. To clean the camera, the part of the condom corresponding to the lens is transparent.

The outer surface of the imaging tube has an elastic shaping rib, which is in an arc shape smaller than a semicircle. The elastic shaping rib has at least one axial long rib and at least one annular connecting rib. The axial long rib is in an arc shape smaller than a semicircle. The axial long rib is axially connected to the outer surface of the imaging tube. When there are multiple axial long ribs, at least one annular connecting rib is annularly connected to the axial long ribs.

The camera tube has an elastic shaping rib in an arc shape smaller than a semicircle. The elastic shaping rib has at least one axial long rib and at least one annular connecting rib. The axial long rib is in an arc shape smaller than a semicircle. The axial long rib is axially connected to the inner surface of the camera tube. When there are multiple axial long ribs, at least one annular connecting rib is annularly connected to the same axial long ribs.

The following will refer to the relevant drawings to illustrate the tracheotomy tube guide device according to the preferred embodiment of the present invention. For ease of understanding, the same components in the following embodiments are illustrated with the same symbols.

Tracheotomy is a tracheotomy, which is to cut a small hole between the third and fourth tracheal ring cartilages (or between the second and third tracheal ring cartilages) and insert a tracheostomy tube as a channel for gas to enter and exit. It is mainly used to provide patients with stable airways but cannot be intubated through the mouth or nose, patients who have not been intubated but are expected to be intubated for more than two weeks, or patients who have been intubated for four to seven days and still need to maintain a smooth airway. Tracheotomy can replace the nasal cavity for breathing, and can also extract sputum from the lower respiratory tract, reducing the resistance of air entering and exiting the nasal cavity or the mouth of the patient after tracheotomy.

The condom 134 is disposable or sterilizable to clean the camera 13. The condom 134 is transparent at the position corresponding to the camera 132. The internal space of the camera tube 12 provides a transmission line to transmit the image from the lens 132 through the image sensor element 131 to the wireless image transmitting module 112, and then the wireless image transmitting module 112 is used to transmit the wireless image to the external display interface. Among them, the image sensor element 131, the wireless image transmitting module 112, the power switch 113, the energy storage battery 111, and the light-emitting element 133 are electrically connected to each other along the commonly used circuit or telecommunication transmission line, which will not be described in detail here.

As shown in FIGS. 1 to 4, the camera tube 12 is inserted into the external tracheostomy tube 2 until the camera head 13 passes through the end of the tracheostomy tube 2 to observe the inside of the living body's trachea 42, so as to prevent the cutting blade, the guide needle, and the end of the tracheostomy tube 2 from penetrating the bottom wall of the living body's trachea 42, thereby preventing other parts of the living body's neck 41 from being injured. Then, when the tracheostomy tube 2 passes through the living body's neck 41 to the living body's trachea 42, the inside of the living body's trachea 42 is viewed through the camera head 13. The camera 13 generates an image and then transmits the image to the operator through the wireless image transmitting module 112.
