Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of medical device technology, specifically to a novel tracheal puncture device. [Background Technology]
[0002] Emergency tracheotomy is the most effective first aid measure for airway obstruction (such as suffocation caused by food entering the airway during eating), because complete airway obstruction can cause death within 5 minutes. If rescue cannot be performed on-site, the patient will not survive until they are transported to the hospital. Therefore, the corresponding tracheotomy device should be easy to learn, easy to operate, and provide stable ventilation, so as to facilitate use by on-site emergency personnel.
[0003] The prior art, CN 220588335 U, an earlier utility model patent application by the applicant, discloses an easy-to-operate tracheotomy device, including a puncture needle, an inner core, and an elastic membrane. One end of the puncture needle has a puncture bevel. By using the inner core and elastic membrane, the state of the elastic membrane can be observed during puncture. When the elastic membrane protrudes from the puncture needle and then returns to its original state, it can be determined that the trachea has been punctured, and the application of force can be stopped at this point, thus preventing puncture into the esophagus and causing an esophageal fistula. However, during use, it was found that the ventilation lacked a certain degree of stability. After puncture, the puncture needle may still move during patient transport, either slipping out and falling off, or slipping in and causing puncture into the esophagus, resulting in an esophageal fistula and failure to provide ventilation.
[0004] In view of this, this case involves in-depth research into the aforementioned issues, which led to the formation of this case. [Utility Model Content]
[0005] This invention aims to solve the technical problem in the prior art where the puncture needle may move during patient transport, causing it to slip out or slide into the esophagus. The invention provides a novel tracheotomy device that, by setting a reinforcing component, prevents the puncture needle from moving during transport after being inserted into the patient's trachea. This avoids the puncture needle from dislodging from the trachea and causing suffocation; it also prevents the puncture needle from piercing the posterior wall of the trachea, causing damage and bleeding, blocking the needle opening and causing suffocation, or even piercing the posterior esophagus and causing a tracheoesophageal fistula.
[0006] This invention is implemented as follows: A novel tracheotomy device includes a reinforcement component for fixing the puncture needle after puncture; the reinforcement component includes an external end, a first extension strip, a first abutment ring, a second extension strip, and a second abutment ring; the left end of the first extension strip is fixedly connected to the external end, and the right end is fixedly connected to the first abutment ring, the plane of the first abutment ring being perpendicular to the extension direction of the first extension strip; one end of the second extension strip is fixedly connected to the external end, and the other end is fixedly connected to the second abutment ring, the plane of the second abutment ring being perpendicular to the extension direction of the second extension strip; the length of the first extension strip is less than the length of the second extension strip, but greater than the length of the puncture needle.
[0007] Furthermore, the first abutment ring is located on the side of the first extension strip away from the second extension strip.
[0008] Furthermore, the outer diameter of the first abutment ring is smaller than the inner diameter of the puncture needle tube; the outer diameter of the second abutment ring is smaller than the inner diameter of the puncture needle tube.
[0009] Furthermore, the distance between the first extension strip and the second extension strip is equal to the inner diameter of the puncture needle.
[0010] Furthermore, the external end is an annular external end, and the outer diameter of the annular external end is larger than the inner diameter of the puncture needle tube.
[0011] Furthermore, the reinforcement component is a deformable reinforcement component made of a deformable material.
[0012] Furthermore, the deformable reinforcement is a stainless steel reinforcement.
[0013] Furthermore, the distance between the first abutment ring and the second abutment ring is 20-25mm.
[0014] Furthermore, the distance between the first abutment ring and the second abutment ring is 15-20mm.
[0015] Furthermore, it also includes the puncture needle, inner core, and elastic membrane.
[0016] The advantages of this utility model are:
[0017] 1. The new tracheal puncture device is equipped with a reinforcing component to prevent the puncture needle from moving during transportation after being inserted into the patient's trachea. This can prevent the puncture needle from falling out of the trachea and also prevent the puncture needle from piercing the posterior wall of the trachea.
[0018] 2. By setting the length of the first extension strip to be greater than the length of the puncture needle, it is ensured that the first extension strip can be inserted into the trachea, and the first abutment ring can pass through the puncture needle and enter the trachea; by setting the length of the first extension strip to be less than the length of the second extension strip, there is a length difference between the first extension strip and the second extension strip. The first extension strip is shorter, so when the puncture needle retracts and comes out, the first abutment ring can abut against the anterior wall of the trachea to prevent the puncture needle from continuing to come out of the trachea, thus playing a limiting role; the second abutment ring is longer, ensuring that there is a certain distance between the puncture needle and the posterior wall of the trachea. The distance that the second abutment ring reaches after entering the trachea and abuts against the posterior wall of the trachea is the farthest distance that the reinforcement can be inserted.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.
[0030] Please see Figures 1 to 3 As shown, this utility model provides a novel tracheotomy device, including a reinforcing member 4 for fixing the puncture needle 1 after puncture; by setting the reinforcing member 4, the puncture needle 1 is prevented from moving during transportation after being inserted into the patient's trachea, thus avoiding the puncture needle 1 from falling out of the trachea and also preventing the puncture needle 1 from piercing the posterior wall 202 of the trachea.
[0031] In this invention, the reinforcement 4 includes an external end 41, a first extension bar 42, a first abutment ring 43, a second extension bar 44, and a second abutment ring 45. The left end of the first extension bar 42 is fixedly connected to the external end 41, and the right end is fixedly connected to the first abutment ring 43. The plane of the first abutment ring 43 is perpendicular to the extension direction of the first extension bar 42. By setting the plane of the first abutment ring 43 to be perpendicular to the extension direction of the first extension bar 42, when the puncture needle tube 1 loosens and is about to slip out, the first abutment ring... 43 can press against the anterior wall 201 of the trachea to prevent the puncture needle 1 from continuing to dislodge; one end of the second extension bar 44 is fixedly connected to the external end 41 and the other end is fixedly connected to the second abutment ring 45, and the plane of the second abutment ring 45 is perpendicular to the extension direction of the second extension bar 44; because the plane of the second abutment ring 45 is perpendicular to the extension direction of the second extension bar 44, when the puncture needle 1 loosens and wants to continue to be inserted forward to the posterior wall 202 of the trachea, the second abutment ring 45 can restrict the puncture needle 1 from continuing to move forward.
[0032] In this invention, the length of the first extension strip 42 is less than the length of the second extension strip 44, but greater than the length of the puncture needle tube 1. Before use, the first extension strip 42 and the second extension strip 44 are arranged in parallel. By setting the length of the first extension strip 42 to be greater than the length of the puncture needle tube 1, it is ensured that the first extension strip 42 can be inserted into the trachea, and the first abutment ring 43 can pass through the puncture needle tube 1 and enter the trachea. By setting the length of the first extension strip 42 to be less than the length of the second extension strip 44, there is a length difference between the first extension strip 42 and the second extension strip 44. The first extension strip 42 is shorter, so when the puncture needle tube 1 retracts and comes out, the first abutment ring 43 can abut against the front wall 201 of the trachea, preventing the puncture needle tube 1 from continuing to come out of the trachea, thus playing a limiting role. The second abutment ring 45 is longer, ensuring that there is a certain distance between the puncture needle tube 1 and the rear wall 202 of the trachea. The distance that the second abutment ring 45 reaches after entering the trachea 20 and abuts against the rear wall 202 of the trachea is the farthest distance that the reinforcement 4 can be inserted.
[0033] In this utility model, the first abutting ring 43 is located on the side of the first extension strip 42 away from the second extension strip 44, that is, the orientation of the first abutting ring 43 is opposite to the inner hole direction of the puncture needle tube 1, so that it can stick to the front wall 201 of the trachea when the puncture needle tube 1 is about to fall off, and play a role in limiting and reinforcing the puncture needle tube 1.
[0034] In this invention, in order to enable the first abutment ring 43 and the second abutment ring 45 to pass smoothly through the puncture needle tube 1 and enter the trachea 20, the outer diameter of the first abutment ring 43 is smaller than the inner diameter of the puncture needle tube 1; and the outer diameter of the second abutment ring 45 is smaller than the inner diameter of the puncture needle tube 1.
[0035] In this invention, the distance between the first extension strip 42 and the second extension strip 44 is equal to the inner diameter of the puncture needle tube 1. If the distance between the first extension strip 42 and the second extension strip 44 is greater than the inner diameter of the puncture needle tube 1, the first extension strip 42 and the second extension strip 44 will not adhere to the inner wall of the puncture needle tube 1, and the first extension strip 42 and the second extension strip 44 will be in a crossed state inside the tube, thus failing to achieve a fixing effect.
[0036] In this invention, the external end 41 is an annular external end 41, which serves to connect the first abutment ring 43 and the second abutment ring 45. The outer diameter of the annular external end 41 is larger than the inner diameter of the puncture needle tube 1, preventing the annular external end 41 from entering the interior of the puncture needle tube 1. It also restricts the puncture needle tube 1 from sliding out when it becomes loose. Simultaneously, the annular arrangement of the external end 41 allows for easy deformation of the first extension strip 42 and the second extension strip 44.
[0037] In this invention, the reinforcing member 4 is a deformable reinforcing member made of a deformable material. Preferably, the deformable reinforcing member 4 is a stainless steel reinforcing member 4. In use, the first extension bar 42 and the second extension bar 44 are pressed to deform them, so that the second abutment ring 45 and the first abutment ring 43 sequentially enter the puncture needle tube 1.
[0038] In this invention, the distance between the first abutment ring 43 and the second abutment ring 45 is 20-25 mm. The diameter of the human trachea is related to age; the diameter of the adult trachea is 20-25 mm.
[0039] In this invention, the distance between the first abutment ring 43 and the second abutment ring 45 is 15-20 mm. The diameter of the human trachea is related to age; the diameter of a child's trachea is 15-20 mm.
[0040] Operating principle: After the puncture needle 1 is inserted into the patient's trachea 20, press the first extension strip 42 and the second extension strip 44 of the reinforcement 4 to deform it, insert the reinforcement 4 into the puncture needle until the first abutment ring 43 enters the trachea 20, and release the reinforcement 4 to achieve the limiting and reinforcement of the puncture needle 1.
[0041] Please refer to Figure 4 to Figure 7 As shown, the novel tracheal puncture device also includes a puncture needle tube 1, an inner core 2, and an elastic membrane 3. One end of the puncture needle tube 1 is provided with a puncture bevel 11, and the other end of the puncture needle tube 1 is a connecting end 12. A channel 13 is formed inside the puncture needle tube 1, and a limiting ring 14 is formed by protrusions on the inner side wall of the channel 13. The inner core 2 includes a sleeve section 21 and a protruding section 22. The sleeve section 21 is movably disposed in the channel 13. The protruding section 22 is integrally formed with the sleeve section 21. A limiting step 23 is formed between the protruding section 22 and the sleeve section 21, which abuts against the limiting ring 14. The inner diameter of the protruding section 22 is smaller than the inner diameter of the sleeve section 21, and the end of the protruding section 22 can protrude from the puncture needle tube 1. The end of the elastic membrane 3 is disposed on the connecting end 12. The elastic membrane 3 covers the channel 13 and is elastic and can be lifted by the inner core 2.
[0042] In use, the puncture bevel 11 of the puncture needle 1 is inserted into the patient's neck skin 10. Then, force is applied to the puncture needle 1, causing it to slowly penetrate. The inner core 2 is blocked by the soft tissue of the neck and cannot advance, resulting in relative movement between the inner core 2 and the puncture needle 1. This causes the elastic membrane 3 to be pushed up by the inner core 2 until the end of the protruding section 22 of the inner core 2 abuts against the outer wall of the trachea 20. Force is continued to be applied to the puncture needle 1. At this time, the inner core 2 is blocked by the outer wall of the trachea 20 and cannot advance. The elastic membrane 3 is still in the pushed-up state. When the puncture bevel 11 pierces into the trachea 20, the protruding section 22 of the inner core 2 is no longer blocked and protrudes into the trachea 20, causing the elastic membrane 3 to return to its original state. It can be determined that the puncture needle 1 is located in the trachea 20. At this time, the force is stopped, thereby effectively preventing the puncture needle 1 from being inserted into the esophagus 30 and causing an esophageal fistula.
[0043] By setting the limiting step 23 and the limiting ring 14, the inner core 2 is effectively prevented from detaching from the puncture needle tube 1 during the delivery of the tracheal puncture device. At the same time, after the puncture bevel 11 is inserted into the trachea 2, when the elastic membrane 3 returns to its original shape, the elastic membrane 3 will give the inner core 2 an elastic force, causing the limiting step 23 of the inner core 2 to spring onto the limiting ring 14, thereby preventing the inner core 2 from springing into the patient's body.
[0044] Preferably, the outer wall of the other end of the puncture needle tube 1 protrudes to form a limiting block 15 that restricts the elastic membrane 3; an elastic ring 31 that cooperates with the limiting block 15 is provided at the end of the elastic membrane 3. When connecting the elastic membrane 3 to the puncture needle tube 1, force is applied to the elastic ring 31 to open the opening of the elastic ring 31, and then the elastic ring 31 is passed around the limiting block 15 and inserted into the puncture needle tube 1. The elastic ring 31 is then released so that the limiting block 15 is located inside the elastic membrane 3, thereby preventing the elastic membrane 3 from detaching from the puncture needle tube 1 during use. After the puncture bevel 11 is inserted into the trachea 20, the elastic membrane 3 can be cut open, the inner core 2 can be removed, and finally oxygen can be introduced into the patient's body through the puncture needle tube 1.
[0045] Preferably, the end of the protruding section 22 forms a plane 221. By forming a plane 221 at the end of the protruding section 22, the end of the protruding section 22 can effectively abut against the outer wall of the trachea 20, preventing the end of the protruding section 22 from penetrating the trachea 20 first.
[0046] Compared with the prior art, this utility model, by setting an inner core 2 and an elastic membrane 3, can observe the state of the elastic membrane 3 during puncture. When the elastic membrane 3 protrudes from the puncture needle tube 1 and then returns to its original state, it can be determined that the puncture has reached the trachea 20. At this time, the force is stopped, thereby preventing the puncture from reaching the esophagus 30 and causing an esophageal fistula.

Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
