Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, the embodiment of the present invention provides a tracheal puncture device for emergency use, including a tracheal puncture device body, which includes a syringe 1 and a breathable puncture needle 101 connected to the left side thereof. The outer left movable sleeve of the syringe 1 is provided with a quick-adjustable needle guard limit mechanism.

[0025] The quick-adjustable needle guard limiting mechanism includes a movable sleeve on the left side of the outer side of the syringe 1. The adhesive sleeve inside the sleeve 2 is provided with an elastic damping rubber sleeve 201. The inner side of the elastic damping rubber sleeve 201 is tightly contacted with the left side of the outer side of the syringe 1. The elastic damping rubber sleeve 201 is provided to facilitate personnel to conveniently connect and remove the sleeve 2 and the syringe 1, and use its own elastic force to maintain the stable connection between the sleeve 2 and the syringe 1. The left side of the sleeve 2 is fixedly connected to an inner tube 3 with a hood-shaped structure at the right end. The sliding sleeve on the inner tube 3 is provided with an outer tube 4. The bottom of the inner tube 3 is provided with a limiting groove. The bottom inner wall of the outer tube 4 is fixedly connected with a limiting block slidably connected to the limiting groove, which plays the effect of horizontally guiding and limiting the outer tube 4 to prevent it from falling off. The top of the inner tube 3 is embedded with a fixed A hard non-slip rubber pad 9 is provided, wherein the top of the inner tube 3 is provided with an embedding groove which is bonded and fixed to the outer side of the hard non-slip rubber pad 9, and a spring-loaded locking component which is tightly contacted with the top of the hard non-slip rubber pad 9 is embedded and fixed on the right side of the top of the outer tube 4. A warning light 8 is fixedly connected to the top of the left side of the ferrule 2, and a battery for powering the warning light 8 is built in the warning light 8. A penetrable shielding touch component electrically connected to the warning light 8 is installed on the outer tube 4. A circular through hole is provided on the left side of the ferrule 2, and a breathable puncture needle 101 is located in the circular through hole and does not contact the inner wall of the circular through hole, so as to allow the breathable puncture needle 101 to pass through. The breathable puncture needle 101 is located in the inner tube 3 and the outer tube 4, and the front side of the inner tube 3 is provided with a scale line 15 which matches the right end of the outer tube 4;

[0026] The outer tube 4 and the inner tube 3 are used to shield and protect the breathable puncture needle 101 when not in use. The spring-loaded locking component is used to lock the outer tube 4 and to unlock and move the outer tube 4 horizontally by simply pulling. The scale line 15 provided is convenient for personnel to accurately adjust the outer tube 4 to the right according to the puncture depth requirements, so as to achieve convenient and accurate adjustment of the exposed length of the breathable puncture needle 101. The penetrable shielding touch component is used to allow the breathable puncture needle 101 to automatically penetrate when the outer tube 4 moves to the right, and is used to limit the puncture length during the puncture work and control the prompt light 8 to turn on when the puncture length is reached to accurately remind personnel, and is used to temporarily protect the breathable puncture needle 101 again when it is temporarily stored or carried after puncture.

[0027] Specifically, the spring-loaded locking assembly includes a fixing sleeve 10 embedded and fixed on the right side of the top of the outer tube 4, wherein the right side of the top of the outer tube 4 is provided with an embedding hole fixedly connected to the outside of the fixing sleeve 10, and the top of the fixing sleeve 10 is provided with a blocking structure. The sliding sleeve in the fixing sleeve 10 is provided with a pressure block 11, and the top of the pressure block 11 is fixedly connected to a T-shaped pull rod 14, and the fixing sleeve 10 is slidingly sleeved on the T-shaped pull rod 14, wherein the top of the fixing sleeve 10 is provided with a vertical guide hole that is slidably sleeved on the outside of the T-shaped pull rod 14, which plays the effect of allowing the bottom end of the T-shaped pull rod 14 to pass through and guide its vertical sliding, and a compression spring 13 in a compressed state is fixedly connected between the top of the pressure block 11 and the top inner wall of the fixing sleeve 10, and the compression spring 13 is movably sleeved on the T-shaped pull rod On the rod 14, a plurality of pointed blocks 12 are fixedly connected to the bottom of the pressure block 11, and the tips of the pointed blocks 12 are tightly contacted with the top of the hard anti-slip rubber pad 9; the fixed sleeve 10, pressure block 11, T-shaped pull rod 14, compression spring 13 and pointed block 12 are coordinated, and the elastic force of the compression spring 13 in the compressed state is used to elastically tighten the pressure block 11 downward, so as to drive the pointed blocks 12 to be tightly squeezed with the hard anti-slip rubber pad 9, thereby locking the position of the outer tube 4. When unlocking and adjusting, pull up the T-shaped pull rod 14 to drive the pressure block 11 to compress the compression spring 13 upward, and the pressure block 11 drives the pointed blocks 12 to separate from the hard anti-slip rubber pad 9, releasing the locked state, and move the T-shaped pull rod 14 to the right so that it drives the outer tube 4 to move to the right through the fixed sleeve 10 to adjust the limit distance.

[0028] Furthermore, the penetrable shielding touch assembly includes a limiting sleeve 5 slidingly sleeved on the outer tube 4, the left side of the limiting sleeve 5 is set as a blocking structure and is provided with a circular perforation, the adhesive sleeve inside the circular perforation is provided with a medical silicone sheet 6, and the right side of the medical silicone sheet 6 is provided with a cross-shaped seam 601 adapted to the breathable puncture needle 101, and two spring non-locking squeeze touch switches 7 are fixedly connected between the left end of the outer tube 4 and the left inner wall of the limiting sleeve 5. The two spring non-locking squeeze touch switches 7 are both electrically connected to the prompt light 8, and the two spring non-locking squeeze touch switches 7 are connected in parallel; the setting of the limiting sleeve 5, the medical silicone sheet 6, the cross-shaped seam 601 and the spring non-locking squeeze touch switch 7 are equipped with a plurality of protective films. When the outer tube 4 is adjusted to the right, the limiting sleeve 5 is driven to move right, and the limiting sleeve 5 drives the medical silicone sheet 6 to move right. The medical silicone sheet 6 is placed on the breathable puncture needle 101 through the cross-shaped seam 601 to allow its left end to pass through. During the puncture work, the limiting sleeve 5 is used to limit the maximum puncture length of the breathable puncture needle 101. When the transmission reaches the limit length, the human skin squeezes the limiting sleeve 5, and the limiting sleeve 5 squeezes and touches the two spring-free locking squeeze touch switches 7. The two spring-free locking squeeze touch switches 7 control the prompt light 8 to turn on, thereby achieving the effect of limiting the puncture length and automatically reminding personnel when the puncture length is reached, so that medical personnel can know in time to stop the puncture work.

[0029] The method of use of this embodiment is as follows: when the emergency tracheal puncture device is used, first pull the T-shaped pull rod 14 upward to drive the pressure block 11 to move upward, and compress the compression spring 13, so that the pressure block 11 drives the tip block 12 to separate from the hard anti-slip rubber pad 9, releasing the locked state. At this time, move the T-shaped pull rod 14 to the right to drive the outer tube 4 to move to the right through the fixing sleeve 10, and the outer tube 4 drives the limiting sleeve 5 to move to the right, and the limiting sleeve 5 drives the medical silicone sheet 6 to move to the right. The medical silicone sheet 6 is placed on the breathable puncture needle 101 through the cross-shaped seam 601 for its left end to pass through. By observing the position where the right end of the outer tube 4 is aligned with the scale line 15, the exposed length of the breathable puncture needle 101 is judged. After the exposed length is adjusted to be appropriate, relax the tension on the T-shaped pull rod 14. At this time, the elastic force of the compression spring 13 in the compressed state drives the pressure block 11 to move back downward, and the pressure block 11 drives the tip block 1 When the needle is inserted into the skin, the needle 101 is tightened and the locking mechanism 5 is in place, so that the needle 101 can be inserted into the skin more easily.

[0030] After use, if the syringe 1 and the breathable puncture needle 101 are used to extract the accumulated fluid for temporary storage for inspection, the personnel will pull up the T-shaped pull rod 14 again to release the lock on the outer tube 4, and then move the T-shaped pull rod 14 to the left so that it drives the outer tube 4 to move back to the left through the fixing sleeve 10 to reset. The outer tube 4 drives the limiting sleeve 5 to move back to the left to reset. The limiting sleeve 5 drives the medical silicone sheet 6 to the left and separates from the breathable puncture needle 101. At this time, the middle part of the medical silicone sheet 6 rebounds by itself under its own elastic force After the needle 101 is reset, the outer tube 4, the inner tube 3 and the limiting sleeve 5 again surround and protect the ventilating puncture needle 101, so that after the effusion is extracted, the ventilating puncture needle 101 can be quickly and safely protected by pulling the upper part and moving it horizontally. Compared with the method of protecting the tip of the ventilating puncture needle 101 through a conventional sheath needle sleeve, the risk of cross infection caused by accidental puncture by the ventilating puncture needle 101 is effectively reduced, thereby improving the safety of use.

[0031] When the syringe 1 needs to be discarded after subsequent use, the personnel can directly pull the ferrule 2 to the left to drive the elastic damping rubber sleeve 201 to separate from the syringe 1, thereby realizing the separation of the quick-adjust needle guard limit mechanism and the syringe 1. The quick-adjust needle guard limit mechanism can be conveniently pulled and separated, which is convenient for subsequent recycling after disinfection with disinfectant, thereby improving practicality.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
