Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary instruments, and particularly relates to an anti-loosening tracheotomy atomization connector. Background Technique

[0002] After tracheotomy surgery, the patient can no longer breathe through the nose. To maintain their vital signs, atomization inhalation is usually used to maintain the patient's vital signs. For patients using a tracheotomy mask, the fitting effect between the tracheotomy mask and the patient's neck is not very good. The tracheotomy mask will move slightly when touched, and often cannot effectively and comprehensively inhale the medicine mist, resulting in a large amount of waste of the medicine mist, affecting the treatment effect, and even possibly causing aspiration and choking cough.

[0003] In the existing patent for a tracheotomy atomization device, in the patent authorization number CN215608541U, by canceling the suction mask on the traditional atomizer, the atomizer and the tracheotomy cannula are adaptively connected through a connecting tube, so that the medicine can completely enter the tracheotomy cannula along the connecting tube and be inhaled by the patient to improve the absorption rate of the medicine. In addition, the gap between the inner tube and the connecting tube is used for the tracheotomy cannula nozzle to be wedged in, which not only facilitates the insertion of the connecting tube, but also improves the stability of the connection between the connecting tube and the tracheotomy cannula, thus avoiding the situation that the connecting tube moves or falls off and affects the treatment effect.

[0004] Some existing tracheotomy atomization devices usually use a plug-in method to connect the atomization tube and the tracheotomy tube. Although this connection method is convenient, its stability is not good. It not only easily causes loosening at the connection part, but also causes leakage of the atomized medicine, thus affecting the atomization effect. For this reason, we propose an anti-loosening tracheotomy atomization connector. Content of the Utility Model

[0005] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose an anti-loosening tracheotomy atomization connector.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design an anti-loosening tracheotomy atomization connector, including a tracheotomy cannula and an atomizer conductively connected to the tracheotomy cannula. The connection end of the tracheotomy cannula is provided with an external thread, and a limiting boss fixedly connected to the outer wall of the tracheotomy cannula is arranged at the root of the external thread. A flange integrally formed with the tracheotomy cannula is arranged between the limiting boss and the external thread, and a damping rubber ring is inlaid on the outer wall of the flange;

[0008] The top end of the outer wall of the atomizer is conductively connected with an atomization tube, and the atomization tube is a flexible rubber tube. A hard connection head is integrally formed at the connection end of the atomization tube, and a limiting ring is fixedly connected to the outer wall of the hard connection head;

[0009] A connecting sleeve is rotatably connected to the limiting ring, and an internal thread that is screwed with the external thread is provided on the inner wall of the connecting sleeve.

[0010] Preferably, a stepped portion is provided at the connecting end of the connecting sleeve, and the inner wall of the stepped portion abuts against the damping rubber ring.

[0011] Preferably, a sealing rubber ring is embedded on the outer wall of the end of the rigid connecting head, and the sealing rubber ring abuts against the inner wall of the tracheotomy cannula.

[0012] Preferably, a limiting portion in a ring structure is provided at one end of the connecting sleeve close to the limiting ring, and the limiting portion fits with the limiting ring.

[0013] Preferably, the inner diameter of the limiting portion is adapted to the outer diameter of the rigid connecting head.

[0014] Preferably, an elastic hanging rope is connected to the outer wall of the atomizer.

[0015] The beneficial effects of an anti-loosening tracheotomy atomization connector proposed by the present utility model are as follows:

[0016] 1. The rigid connecting head provided at the end of the atomization tube is inserted and connected to the inner cavity of the tracheotomy cannula. Then, hold the limiting boss to fix the tracheotomy cannula, and then make the connecting sleeve rotate together with the rigid connecting head. At the same time, use the limiting ring to limit the connecting sleeve, so that the internal thread of the connecting sleeve is screwed with the external thread of the connecting end of the tracheotomy cannula until the end of the connecting sleeve abuts against the limiting boss, and use the damping rubber ring to increase the friction force with the connecting sleeve, thereby preventing the connecting sleeve from loosening, and further effectively avoiding the separation between the atomization tube and the tracheotomy cannula, and ensuring the atomization effect.

[0017] 2. By using the sealing rubber ring to fill the gap at the combined part of the rigid connecting head and the tracheotomy cannula, the leakage of the atomized medicine is avoided, so as to ensure the atomization effect. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Referring to Figures 1-5 , a loosening-preventing tracheotomy atomizing connector includes a tracheotomy cannula 1 and an atomizer 2 that is conductively connected to the tracheotomy cannula 1. An external thread 3 is provided at the connection end of the tracheotomy cannula 1. A limiting boss 4 fixedly connected to the outer wall of the tracheotomy cannula 1 is provided at the root of the external thread 3. A flange 5 integrally formed with the tracheotomy cannula 1 is provided between the limiting boss 4 and the external thread 3. A damping rubber ring 6 is embedded in the outer wall of the flange 5;

[0026] The top end of the outer wall of the atomizer 2 is conductively connected to an atomizing tube 7, and the atomizing tube 7 is a flexible rubber tube. A hard connector is integrally formed at the connection end of the atomizing tube 7, and a limiting ring 8 is fixedly connected to the outer wall of the hard connector;

[0027] A connecting sleeve 9 is rotatably connected to the limiting ring 8, and an internal thread 10 that is screwed with the external thread 3 is provided on the inner wall of the connecting sleeve 9;

[0028] It should be noted that when the loosening-preventing tracheotomy atomizing device connector is in use, first place the tracheotomy cannula 1 at the throat incision site of the patient, then add atomizing liquid medicine into the inner side of the atomizer 2, and then insert and connect the hard connector provided at the end of the atomizing tube 7 with the inner cavity of the tracheotomy cannula 1. Then hold the limiting boss 4 to fix the tracheotomy cannula 1, and then make the connecting sleeve 9 rotate together with the hard connector. At the same time, use the limiting ring 8 to limit the connecting sleeve 9, so that the internal thread 10 of the connecting sleeve 9 is screwed with the external thread 3 at the connection end of the tracheotomy cannula 1 until the end of the connecting sleeve 9 abuts against the limiting boss 4, and use the damping rubber ring 6 to increase the friction with the connecting sleeve 9, thereby preventing the connecting sleeve 9 from loosening, and further effectively avoiding the separation between the atomizing tube 7 and the tracheotomy cannula 1, and ensuring the atomizing effect.

[0029] Such as Figure 2 、 Figure 5As shown, a stepped portion is provided at the connecting end of the connecting sleeve 9, and the inner wall of the stepped portion abuts against the damping rubber ring 6;

[0030] It should be noted that when the end of the connecting sleeve 9 abuts against the limiting boss 4, the stepped portion provided at the end of the connecting sleeve 9 abuts against the damping rubber ring 6, thereby increasing the friction force with the connecting sleeve 9 and preventing the connecting sleeve 9 from loosening.

[0031] As Figure 1 、 Figure 5 shown, a sealing rubber ring 11 is inlaid on the outer wall of the end of the rigid connecting head, and the sealing rubber ring 11 abuts against the inner wall of the tracheotomy cannula 1;

[0032] It should be noted that by using the sealing rubber ring 11 to fill the gap at the combined part of the rigid connecting head and the tracheotomy cannula 1, the leakage of the atomized medicine is avoided, so as to ensure the atomization effect.

[0033] As Figure 5 shown, a limiting portion in a ring structure is provided at one end of the connecting sleeve 9 close to the limiting ring 8, and the limiting portion fits with the limiting ring 8, and the inner diameter of the limiting portion is adapted to the outer diameter of the rigid connecting head;

[0034] It should be noted that by using the limiting ring 8 to limit the connecting sleeve 9, the connecting sleeve 9 is prevented from detaching from the atomizing tube 7, and at the same time, the stability of the connecting sleeve 9 during rotation is ensured.

[0035] As Figure 1 shown, an elastic hanging rope 12 is connected to the outer wall of the atomizer 2;

[0036] It should be noted that the atomizer 2 is hung on the patient's neck through the elastic hanging rope 12, which is convenient for carrying the atomizer 2.

[0037] Working principle: During use, first place the tracheotomy cannula 1 at the incision site of the patient's larynx, then add the atomized medicine into the inner side of the atomizer 2, and then insert and connect the rigid connecting head provided at the end of the atomizing tube 7 with the inner cavity of the tracheotomy cannula 1. Then hold the limiting boss 4 to fix the tracheotomy cannula 1, and then make the connecting sleeve 9 rotate together with the rigid connecting head. At the same time, use the limiting ring 8 to limit the connecting sleeve 9, so that the internal thread 10 of the connecting sleeve 9 is screwed with the external thread 3 at the connecting end of the tracheotomy cannula 1 until the end of the connecting sleeve 9 abuts against the limiting boss 4, and use the damping rubber ring 6 to increase the friction force with the connecting sleeve 9, thereby preventing the connecting sleeve 9 from loosening, and further effectively avoiding the separation between the atomizing tube 7 and the tracheotomy cannula 1.

[0038] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
