Description

Portable tracheostomy device The present invention relates to a tracheostomy device, in particular to a portable tracheostomy device. Tracheotomy is a mature puncture technique that can be performed by trained professionals. It is also a required training subject for US special forces to maintain human breathing in emergencies during war. In addition, when various disasters occur (such as war, fire, flood, tsunami, air pollution) and toxic gases produced, or allergens produced by nature, there is a chance that the upper respiratory tract will swell and block the trachea. When the upper respiratory tract is blocked, how to establish the airway using tracheotomy technology is the key to saving lives. Among them, nurse training is divided into four levels. First-level nurses are not able to use tracheotomy technology, while nurses at other levels can perform tracheotomy in critical situations. Refer to Figure 1, which is patent CN 108378907 A, illustrating a puncture ventilation kit 1, comprising a puncture needle 11, a puncture handle 12, a respiratory connection interface 13, a balloon push handle 14, an external fixation balloon 15, an internal fixation balloon 16, a ventilation inner sheath 17, and a balloon push outer sheath 18. The ventilation inner sheath 17 can be connected to a ventilator for ventilation. The balloon push handle 14 pushes the balloon push outer sheath 18. The external fixation balloon 15 is positioned outside the skin, while the internal fixation balloon 16 is fixed in the trachea. Although the prior art discloses a puncture ventilation kit 1, it still has the following disadvantages in actual use: 1. Complex structure and difficult to operate: Conventional tracheostomy tools are not only equipped with a puncture structure, but also with a telescopic structure that can change the length, an airbag structure that can expand and contract, and an interface structure for connecting to a ventilator. They are a special puncture tool used in hospitals or operating rooms. Their structure is too complicated and their use requires following a certain procedure. It is difficult for people who have not learned the usage procedure to use them. 2. Unable to judge the puncture depth externally or in a dim environment: Generally, there is no length scale on the surface of the tracheotomy tool. Therefore, the puncture operation must be performed by professionals to avoid damaging blood vessels and accurately enter the trachea. However, nurses who have only received simple training do not have much operating experience. If they cannot know the puncture depth, errors are likely to occur. In addition, the general length scale can only be viewed but not touched, and cannot be checked and used externally or in a dim environment. 3. Difficult to carry around: Generally, tubular tracheostomy tools have many components and there is no structure on the outer surface to fix the position of clothing. They cannot be directly fixed on clothing, pens and other items. If the tracheostomy tool is placed in a pocket at will, the sharp end of the tracheostomy tool will not only cause punctures to clothing, human tissue and other objects, but also the large number of components makes it easy for some components to fall or be lost during daily activities. It is not designed to be carried around. 4. Prone to infection: In an environment with insufficient medical equipment, that is, in war zones, transportation vehicles, disaster environments such as fire or flood, or general places, disinfection equipment will not be prepared. However, when symptoms of upper respiratory tract obstruction occur, emergency treatment is required in an emergency situation. Unnecessary delays are not allowed during first aid. If a puncture operation is performed under insufficient disinfection conditions, the patient is prone to infection. Therefore, how to design a device that can be safely carried around, can sense the puncture depth by touch, can prevent the tracheotomy tool from sinking into the human body, and can be quarantined and disinfected in environments with insufficient medical equipment before performing puncture surgery is a goal that relevant technical personnel urgently need to work hard on. In view of this, an object of the present invention is to provide a portable tracheostomy device, which includes a tube unit, a puncture unit, and a tail hook unit. The tubular unit includes a tubular body, a first opening structure provided on the tubular body, a second opening structure provided on the tubular body, and a connecting space defined by the tubular body. The first opening structure and the second opening structure are opposite ends of the tubular body, and the connecting space connects the first opening structure and the second opening structure respectively. The puncture unit includes an oblique cut structure provided on the tubular body and located at the first opening structure, and a tip structure connected to the oblique cut structure. The tail hook unit includes a barbed hook structure arranged on the tubular body and located at the second opening structure, and an end opening arranged on the barbed hook structure. The second opening structure is spaced apart from the end opening, and the setting position of the end opening corresponds to the second opening structure. In one embodiment, the inverted hook structure has an extension portion connected to the tubular body, a cross-cut portion connected to the extension portion, and a hook portion connected to the cross-cut portion, the end opening is arranged in the cross-cut portion, the hook portion extends from the cross-cut portion toward the first opening structure, the hook portion is located on the side of the tubular body, and the hook portion is spaced apart from the tubular body. In one embodiment, the outer diameter of the tubular body is gradually widened from the first opening structure to the second opening structure, and the oblique cut structure is in an inwardly curved arc shape, so that the tip structure is sharp. In one embodiment, the tubular unit further includes a length measuring module disposed on the surface of the tubular body. The length measuring module is structured to be convex outward relative to the surface of the tubular body or concave inward relative to the surface of the tubular body. In one embodiment, the tube unit further includes an extension tube detachably extending from the second opening structure into the communication space, and the extension tube is disposed through the end opening. In one embodiment, the portable tracheostomy device further includes a protection unit, which includes a first protective cover that can be detachably mounted on the first opening structure, and a protection space defined by the first protective cover. When the first protective cover is mounted on the first opening structure, the puncture unit is located in the protection space. In one embodiment, the portable tracheostomy device further includes a protective unit, which includes a placement seat that can be detachably inserted into the connecting space, and a clamping structure provided on the placement seat. When the placement seat is inserted into the connecting space, the clamping structure cooperates with the placement seat to clamp the hook structure so that the tubular body is fixed to the surface of the placement seat, and the placement seat extends outward from the first opening structure. In one embodiment, the protection unit further includes a second protective cover that can be detachably mounted on the placement seat. The structure of the second protective cover is tubular. The interior of the second protective cover has a fixing protrusion and a receiving recess. The outside of the placement seat has a fixing recess. The fixing protrusion is combined with the fixing recess to fix the second protective cover on the placement seat. The structure of the receiving recess matches the structure of the puncture unit. The puncture unit is received in the receiving recess so that the second protective cover covers the puncture unit. In one embodiment, the tube unit, the puncture unit and the tail hook unit are integrally formed. In one embodiment, the puncture unit is made of a hard material, and the tube unit and the tail hook unit are made of an elastic soft material. The beneficial effect of the present invention is that the first protective cover can enclose the puncture unit so that it will not cause damage to clothes or the human body when generally stored. The hook structure can be hooked to be hung in the pocket of clothes, which has a certain fixing effect in daily life and is not easy to be lost. In addition, the hook structure can also be fixed on the placement seat of the alcohol pen. When an emergency puncture operation is required, the placement seat can be simply disinfected to effectively reduce the risk of postoperative infection. The length measurement module arranged on the surface of the tubular body has a convex or concave structure. When the portable tracheostomy device of this case is used urgently in a dim environment, the user can know the depth of the puncture by touch. The features and technical contents of the related patent applications of the present invention are clearly presented in the following detailed description of the five embodiments with reference to the drawings. Before proceeding with the detailed description, it should be noted that similar components are represented by the same number. Please refer to FIG. 2 , which shows a first embodiment of a portable tracheostomy device according to the present invention. The portable tracheostomy device comprises a tube unit 3 , a puncture unit 4 , a tail hook unit 5 , and a protection unit 6 . The tubular unit 3 includes a tubular body 31, a first opening structure 32 provided on the tubular body 31, a second opening structure 33 provided on the tubular body 31, a communication space 34 defined by the tubular body 31, and an extension tube 35 detachably extending from the second opening structure 33 into the communication space 34. The puncture unit 4 includes an oblique cut structure 41 disposed on the tubular body 31 and located at the first opening structure 32 , and a tip structure 42 connected to the oblique cut structure 41 . The tail hook unit 5 includes a hook structure 51 disposed on the tubular body 31 and located at the second opening structure 33 , and an end opening 52 disposed on the hook structure 51 . The protection unit 6 includes a first protection cover 61 detachably sleeved on the first opening structure 32 , and a protection space 62 defined by the first protection cover 61 . The tubular body 31 is a cylindrical tube body, the first opening structure 32 and the second opening structure 33 are the opposite ends of the tubular body 31, the connecting space 34 connects the first opening structure 32 and the second opening structure 33 respectively and is connected to the outside world, the puncture unit 4 is connected to the first opening structure 32, and the tail hook unit 5 is connected to the second opening structure 33. In the first embodiment, the tubular unit 3, the piercing unit 4, and the tail hook unit 5 are integrally formed. For example, a sheet of metal may be cut, shaped, welded, and polished using metal forming techniques; a piece of wood may be carved and polished; or clay may be shaped, bisque-fired, glazed, and glazed to form the tubular unit 3, the piercing unit 4, and the tail hook unit 5. The tubular unit 3, the piercing unit 4, and the tail hook unit 5 are constructed from a hard material selected from, but not limited to, ceramic, metal, stainless steel, titanium, hard wood, hard bamboo, and hard plastic. In some embodiments, the puncture unit 4 is made of a hard material, while the tube unit 3 and the tail hook unit 5 are made of a flexible, soft material. For example, the puncture unit 4 is made of a material selected from ceramic, metal, stainless steel, titanium, hard wood, hard bamboo, or a hard plastic material, while the tube unit 3 and the tail hook unit 5 are made of a soft plastic material (e.g., polyethylene terephthalate (PET), polypropylene (PP), thermoplastic polyurethane (TPU), TPO (polyolefin elastomer), TPV (dynamically vulcanized polyolefin elastomer), TPS / TPR (polystyrene elastomer), TPEE (polyether ester elastomer), TPA (polyamide elastomer), etc.), paper, etc. In actual implementation, the puncture unit 4 may also be made of other hard materials, and the tube unit 3 and the tail hook unit 5 may also be made of other soft materials, without limitation. Please refer to Figure 2 for details on the portable tracheostomy device of the present invention being used on a human body 21 to establish an artificial airway in the trachea 211. In the first embodiment, the outer diameter of the tubular body 31 is gradually widened from the first opening structure 32 to the second opening structure 33. The relatively thin first opening structure 32 facilitates entry into the human body 21, and the relatively thick second opening structure 33 allows the extension tube 35 to be easily inserted into the connecting space 34. In actual implementation, the outer diameter of the tubular body 31 may also be a uniformly wide cylindrical tube, but the invention should not be limited thereto. The bevel cut structure 41 is an oblique cut surface on the first opening structure 32, and the tip structure 42 is a sharp end defined by the bevel cut structure 41, which is used to puncture the skin 212 of the human body 21 and enter the trachea 211. The structure of the puncture unit 4 is roughly the same as the existing needle, but is different from the existing tracheotomy cutting scalpel. In the first embodiment, the cross-sectional structure of the bevel cut structure 41 presents an arc shape that bends toward the inside of the first opening structure 32, so that the tip structure 42 is further sharp. In actual implementation, the bevel cut structure 41 can also present other shape structures and should not be limited to this. The second opening structure 33 has an upper opening, and the second opening structure 33 is spaced apart from the end opening 52. The setting position of the end opening 52 corresponds to the upper opening of the second opening structure 33. The extension tube body 35 is passed through the end opening 52. The upper opening of the second opening structure 33 is close to the end opening 52, and the two openings are located on the same straight line. When the extension tube body 35 is passed through the end opening 52, it can enter the connecting space 34 through the upper opening of the second opening structure 33 and then extend outward from the oblique cut structure 41. The extension tube 35 is a flexible tube designed to be inserted into the trachea 211 of the human body 21. This extension tube 35 can be used for suctioning, ventilation, and medication administration. Since the portable tracheostomy device of the present invention is intended for professional use and is not intended to be used for medical treatment, professionals can immediately use the portable tracheostomy device in puncture procedures. Therefore, its use is not described in detail here. In some embodiments, one end of the extension tube 35 can be fitted over and secured to the second opening structure 33 to facilitate suction during use, reducing blood and fluid leakage. After use, the extension tube 35 can be detached from the second opening structure 33. The structure of the first protective cover 61 is similar to that of existing pen covers. The first protective cover 61 is detachably fixed to the first opening structure 32. When the first protective cover 61 is mounted on the first opening structure 32, the puncture unit 4 is located in the protective space 62. The first protective cover 61 isolates the puncture unit 4 from the outside world, thereby preventing the puncture unit 4 from puncturing other objects (such as clothing or human tissue 21). In some embodiments, the overall length of the tube unit 3, the puncture unit 4, and the tail hook unit 5 is 10 cm, and the length of the puncture unit 4 is 1 cm to 2 cm. The first protective cover 61 is a gray rubber protective cover, but this should not be limited to this. The overall structure of the inverted hook structure 51 is in the shape of an inverted hook. The inverted hook structure 51 comprises an extension portion 511 connected to the tubular body 31, a transverse portion 512 connected to the extension portion 511, and a hook portion 513 connected to the transverse portion 512. The extension portion 511 extends outward from the second opening structure 33, the transverse portion 512 is spaced above the second opening structure 33, the end opening 52 is disposed in the transverse portion 512, and the hook portion 513 extends from the transverse portion 512 toward the first opening structure 32. The hook portion 513 is located on the side of the tubular body 31 and spaced apart from the tubular body 31. The transverse portion 512 of the inverted hook structure 51 has a top surface that can be pressed by a finger to apply pressure to puncture the human body 21 with the portable tracheostomy device. The end opening 52 is a through-hole in the center of the transverse portion 512. When the portable tracheostomy device is usually needed to be carried, the hook structure 51 and the tubular body 31 can be used as a clamp to clamp the clothing to fix the portable tracheostomy device on the clothing, and the first protective cover 61 can protect the puncture unit 4 from damage, thereby achieving the purpose of carrying it on the body. Furthermore, because the hook portion 513 is spaced apart from the outside of the tubular body 31, when the portable tracheostomy device is puncturing the human body 21, the bottom end of the hook portion 513 will contact the skin 212, which will interfere with the hook portion 513, thereby preventing the portable tracheostomy device from being completely immersed in the human body 21. Because securing the device is difficult in outdoor environments, the barbed hook structure 51 prevents the tubular body 31 from being pushed into the body by external forces. Please refer to Figure 4, which is a second embodiment of a portable tracheostomy device of the present invention. The second embodiment is substantially the same as the first embodiment, and the similarities are not described in detail here. The difference is that the portable tracheostomy device further includes a protection unit 6, which includes a placement seat 63 that can be detachably inserted into the connecting space 34, and a clamping structure 64 provided on the placement seat 63. Referring to FIG. 5 , in this second embodiment, the placement base 63 is a common alcohol pen, with a bottom end for writing and a top end for pressing to dispense alcohol. The clamping structure 64 is a resilient pressure rod provided on the placement base 63, and its structure is substantially similar to that of a conventional pen clip. In some embodiments, the placement base 63 is 15 cm to 20 cm long, the overall length of the portable tracheostomy device is approximately 10 cm, the length of the puncture unit 4 is approximately 1.5 cm, and the insertion depth of the portable tracheostomy device into the human body 21 is approximately 2 cm to 3 cm. The placement seat 63 can be detachably inserted into the connecting space 34. When the placement seat 63 is inserted into the connecting space 34, the clamping structure 64 and the placement seat 63 cooperate to clamp the hook structure 51, so that the tubular body 31 is fixed to the surface of the placement seat 63, and the placement seat 63 extends outward from the first opening structure 32. When the portable tracheostomy device is carried on the person, it can become a writing tool for writing. When an emergency puncture operation is required in an environment with insufficient medical equipment, the tube unit 3, the puncture unit 4 and the tail hook unit 5 can be separated from the placement seat 63 first, and then the alcohol spraying structure in the placement seat 63 can be used to spray alcohol on the tube unit 3, the puncture unit 4 and the tail hook unit 5 for simple disinfection, and then the puncture unit 4 can be used to perform the puncture operation, which can greatly reduce the risk of postoperative infection. Please refer to FIG6 , which is a third embodiment of a portable tracheostomy device of the present invention. The third embodiment is substantially the same as the first embodiment, and the similarities are not described in detail here. The difference is that the tubular unit 3 further includes a length measuring module 36 disposed on the surface of the tubular body 31 . The length measurement module 36 indicates metric length measurements, but is not limited thereto. The reference (0 cm) of the length measurement module 36 is located at the tip structure 42 . Therefore, the length measurement module 36 can be used to measure the puncture depth of the portable tracheostomy device, allowing the puncture depth to be constantly confirmed during the puncture procedure. Referring to FIG. 7 , the length measurement module 36 is recessed relative to the surface of the tubular body 31. In some embodiments, the length measurement module 36 is formed by stamping or engraving a groove on the surface of the tubular body 31. This allows the operator to confirm the puncture depth by touching the length measurement module 36 with their finger or fingernail, in addition to visually observing the groove. Please refer to Figure 8, which shows a fourth embodiment of a portable tracheostomy device of the present invention. The fourth embodiment is substantially the same as the third embodiment, and the similarities are not described in detail here. The difference is that the structure of the length measurement module 36 is outwardly protruding relative to the surface of the tubular body 31, so that the length measurement module 36 is similar to the protruding structure of Braille. In some embodiments, the length measurement module 36 is printed with paint. When the paint remains on the surface of the tubular body 31 and dries, the protruding structure is directly formed. In some embodiments, the protruding structure is formed by pressing metal into a mold. In some embodiments, the protruding structure can be formed by carving on the surface of wood or bamboo. Continuing with the above, the structure of the length measurement module 36, whether it utilizes a recessed groove structure recessed inwardly relative to the surface of the tubular body 31 or a protruding bump structure protruding outwardly relative to the surface of the tubular body 31, primarily serves the purpose of allowing the operator to determine the puncture depth of the portable tracheostomy device by touch in dimly lit environments, thereby avoiding the dangers of misjudging the puncture. In disasters such as war or fire, the dust generated may be toxic or cause upper airway swelling and obstruction due to allergies, necessitating immediate airway access to prevent suffocation. However, in harsh environments, visibility may be poor. The convex or concave structure of the length measurement module 36 allows the operator to intuitively and accurately confirm the puncture depth during the puncture procedure. Please refer to Figure 9, which is a fifth embodiment of a portable tracheostomy device of the present invention. The fifth embodiment is substantially the same as the second embodiment, and the similarities are not described in detail here. The difference is that the protection unit 6 further includes a second protective cover 65 detachably mounted on the placement seat 63, and the second protective cover 65 is used to isolate the puncture unit 4 from the outside world. The second protective cover 65 is an elastic plastic anti-slip cover. The structure of the second protective cover 65 is tubular. When the second protective cover 65 is mounted on the placement seat 63, it has an anti-slip effect and can assist in writing with the pen. After applying force to the second protective cover 65, the second protective cover 65 can be pushed away from the placement seat 63. The interior of the second protective cover 65 has a fixing protrusion 651 and an accommodating recess 652, and the outer side of the placement seat 63 has a fixing recess 631. The fixing protrusion 651 is combined with the fixing recess 631 to fix the second protective cover 65 on the placement seat 63. In the fifth embodiment, the fixing protrusion 651 is at least one annular protrusion provided on the inner surface of the second protective cover 65, and the fixing recess 631 is at least one annular groove provided on the fixed outer surface of the cover. In actual implementation, the fixing protrusion 651 and the fixing recess 631 can also use other fixed combination structures, and should not be limited to this. The structure of the accommodating recess 652 matches that of the puncture unit 4. The puncture unit 4 is accommodated in the accommodating recess 652, so that the second protective cover 65 covers the puncture unit 4. Although an exploded view of the structure is shown in FIG9 , the second protective cover 65 is in close contact with the surface of the placement base 63. When the tubular unit 3, the puncture unit 4, and the tail hook unit 5 are fixed to the surface of the placement base 63, they protrude outwardly relative to the outer surface of the placement base 63. Without the second protective cover 65 on the outside of the puncture unit 4, clothing or a person 21 would be damaged if they came into contact with the puncture unit 4. The second protective cover 65 covering the puncture unit 4 can prevent damage to clothing or a person 21. In addition, when the puncture unit 4 is accommodated in the accommodating recess 652, the outer surface of the second protective cover 65 is smooth, avoiding any uneven surface structure, which facilitates writing using the placement base 63. When the portable tracheostomy device needs to be used urgently, force is first applied to the second protective cover 65 to disengage the fixing protrusion 651 from the fixing recess 631 and to disengage the second protective cover 65 from the placement seat 63. Then, force is applied to the tail hook unit 5 to disengage the tube unit 3, the puncture unit 4 and the tail hook unit 5 from the placement seat 63. After the tube unit 3, the puncture unit 4 and the tail hook unit 5 are disinfected, the puncture operation can be performed. This device is not only simple to operate but also portable. The portable tracheostomy device of the present invention has a lightweight structure and does not require electrical drive. Trained professionals can use it as a surgical tool in puncture operations such as tracheostomy. In addition, when combined with the first protective cover 61 or the second protective cover 65, it can also protect personnel from being injured by the puncture unit 4 when carried. It can also be made of hard materials such as metal, wood, and ceramics. The overall appearance is similar to a common pen that is easy to carry. It is very suitable for being carried on transportation vehicles such as airplanes to move to other countries for free medical treatment, or in situations where sufficient medical equipment cannot be prepared in wars, fires, floods, etc., to immediately provide first aid to patients with upper airway obstruction. Even if a patient with upper airway obstruction is encountered on the airplane, the placement seat 63 can be immediately disinfected and the portable tracheostomy device can be used to perform puncture surgery to save the patient in the golden rescue time. In some embodiments, instructions for use are also provided on the outer surface of the tubular body 31. For example, link information (such as a QR code) can also be printed on the surface of the tubular body 31, and a mobile phone can be used to link to a related website to provide technical specifications, precautions, usage methods and other information of the portable tracheostomy device. In addition, the portable tracheostomy device of the present invention further includes an auxiliary unit associated with the puncture unit 4, the auxiliary unit including an auxiliary control module, a photographic module connected to the auxiliary control module, and a display module connected to the auxiliary control module. The photographic module is used to capture an image of the throat of the human body 21. The auxiliary control module analyzes the image data captured by the photographic module to analyze the position of the throat and trachea 211 of the human body 21, and further indicates the usage area of ​​the puncture unit 4. The auxiliary control module displays the analysis data on the display module to assist the operator in performing the puncture operation. From the above description, it can be seen that the portable tracheostomy device of the present invention has the following effects: 1. Simple structure and easy to use: The structure of the tube unit 3, the puncture unit 4 and the tail hook unit 5 is a simple one-piece molding. The outer diameter width of the tubular body 31 is gradually widened from the first opening structure 32 to the second opening structure 33. The relatively thin first opening structure 32 is easy to enter the human body 21, and the relatively thick second opening structure 33 provides the extension tube body 35 for easy insertion into the connecting space 34. The present invention does not have any telescopic structure, nor is an airbag structure set. People with basic puncture technology can use it directly. 2. Convenient for confirming the puncture depth in a poorly lit environment: The length measurement module 36 is used to measure the puncture depth of the portable tracheostomy device, and its structure is a groove structure that is recessed inward relative to the surface of the tubular body 31, or a bump structure that is protruding outward relative to the surface of the tubular body 31, allowing the operator to confirm the puncture depth of the portable tracheostomy device by touch in a dim environment, thereby avoiding danger caused by misjudgment. 3. Convenient for users to carry with them: The first protective cover 61 and the second protective cover 65 are used to isolate the puncture unit 4 from the outside world to prevent the puncture unit 4 from causing damage to clothes or the human body 21. The hook structure 51 can fix the tubular body 31 on the clothes. The overall structure is lightweight and suitable for people to carry with them during transportation, so that they can be used immediately in emergency situations such as free clinics, wars, and disasters. 4. Effectively reduce the risk of infection: The placement seat 63 is an alcohol pen. The bottom of the alcohol pen can be used for writing, and the top can be pressed to spray alcohol. In places where medical equipment is insufficient, the alcohol in the placement seat 63 can be used to perform a simple disinfection operation on the tube unit 3, the puncture unit 4 and the tail hook unit 5 with alcohol to greatly reduce the risk of infection. To sum up, the hook structure 51 is in the shape of a hook on the second opening structure 33, which can not only fix the tubular body 31 on the clothing, but also support the skin 212 during surgery to prevent the entire body from being immersed in the human body 21. The first protective cover 61 and the second protective cover 65 can isolate the puncture unit 4 from the outside world to prevent the puncture unit 4 from causing damage to clothing, the human body 21 or other objects. The end opening 52 provides the placement seat 63 to pass through, and also provides the extension tube 35 to penetrate into the connecting space 34 and extend outward from the oblique cut structure 41. The placement seat 63 can fix the position of the tubular body 31 and provide alcohol for simple disinfection, so the purpose of the present invention can indeed be achieved. However, the above are only five embodiments of the present invention and should not be used to limit the scope of implementation of the present invention. In other words, simple equivalent changes and modifications made according to the scope of the patent application and the content of the invention description of the present invention are still within the scope of the patent of the present invention. 1: Puncture ventilation kit 11: Puncture needle 12: Puncture handle 13: Respiratory connection interface 14: Balloon push handle 15: External fixation balloon 16: Internal fixation balloon 17: Ventilation inner sheath 18: Balloon push outer sheath 21: Human body 211: Trachea 212: Skin 3: Tube unit 31: Tubular body 32: First opening structure 33: Second opening structure 34: Connecting space 35: Extended tube 36: Length measurement module 4: Puncture unit 41: Bevel cut structure 42: Tip structure 5: Tail hook unit 51: Barbed hook structure 511: Extension portion 512: Cross-cut portion 513: Hook portion 52: End opening 6: Protective unit 61: First protective cover 62: Protective space 63: Placement seat 631: Fixed recess 64: Clamping structure 65: Second protective cover 651: Fixed protrusion 652: Accommodating recess Figure 1 is a stereoscopic schematic diagram of CN 108378907 A; Figure 2 is a stereoscopic schematic diagram of a first embodiment of a portable tracheostomy device of the present invention; Figure 3 is a schematic diagram of the first embodiment in use; Figure 4 is a stereoscopic schematic diagram of a second embodiment of a portable tracheostomy device of the present invention; Figure 5 is a schematic diagram of the second embodiment in use; Figure 6 is a stereoscopic schematic diagram of a third embodiment of a portable tracheostomy device of the present invention; Figure 7 is a partial side schematic diagram of the third embodiment; Figure 8 is a partial side schematic diagram of a fourth embodiment of a portable tracheostomy device of the present invention; and Figure 9 is a side sectional schematic diagram of a fifth embodiment of a portable tracheostomy device of the present invention. 3: Tube unit 31: tubular body 32: First opening structure 33: Second opening structure 34: Connected Space 4:Puncture unit 41: Bevel cut structure 42: Tip Structure 5: Tail hook unit 51: Inverted hook structure 511: Extension 512: cross-section 513: hook part 52: Open end 6: Protection unit 61: first protective cover 62: Protected Space
