DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] As Figures 1 to 4 shown, an anti-disconnection drainage tube includes a tube body 1. An anti-disconnection mechanism is sleeved outside the tube body 1. The anti-disconnection mechanism includes an anti-disconnection member 2 and an insertion sleeve 3. The anti-disconnection member 2 includes a plurality of clip pieces 21 arranged at intervals. There is a notch 27 between adjacent two clip pieces 21. The plurality of clip pieces 21 can form a clip sleeve. The clip sleeve is sleeved outside the tube body 1. The insertion sleeve 3 is sleeved outside the clip sleeve. The insertion sleeve 3 includes an annular rib 32. The inner side of the annular rib 32 can abut against and squeeze the clip sleeve so that the clip sleeve abuts against and squeezes the outer wall of the tube body 1. Specifically, the inner diameter dimension of the annular rib 32 is smaller than the outer diameter dimension of the clip sleeve. A support ring 22 is provided on the upper part of the anti-disconnection member 2. The support ring 22 is located outside the clip sleeve. A cavity 23 is formed between the support ring 22 and the clip sleeve. The annular rib 32 is inserted into the cavity 23. A plurality of limit openings 24 are provided on the side wall of the support ring 22. A boss 33 corresponding to the limit opening 24 is provided on the outer wall of the annular rib 32. The boss 33 can be inserted into the limit opening 24 for limiting. The insertion sleeve 3 includes an annular cover 31 located above the annular rib 32. The lower part of the annular cover 31 can abut against the upper part of the support ring 22. When the anti-disconnection member 2 and the insertion sleeve 3 are separated, both can move freely along the tube body 1. When it is necessary to fix the tube body 1, the annular rib 32 is inserted into the cavity 23. At this time, the annular rib 32 can squeeze the clip pieces 21, causing the clip pieces 21 to deform towards the tube body 1. The clip pieces 21 abut against and squeeze the tube body 1, thereby realizing the fixation of the tube body 1 and the anti-disconnection mechanism. A connecting piece 4 is provided at the lower part of the anti-disconnection member 2. A sticking part 5 is provided on the lower surface of the connecting piece 4. By providing the sticking part 5, the anti-disconnection mechanism can be stuck and fixed on the skin surface of the patient, realizing the anti-disconnection function of the tube body 1, which is convenient to operate and greatly reduces the risk of the tube body 1 being pulled out.
[0024] The upper part of the anti - detachment member 2 is provided with an annular support rib 26. The upper part of the annular support rib 26 is provided with a connecting rib 25. The upper part of the connecting rib 25 is connected to the lower part of the clip 21. The connection part between the connecting rib 25 and the clip 21 can be deformed so that the clip 21 can move. Specifically, the connecting rib 25 and the clip 21 are in arc transition, the connecting rib 25 and the support rib 26 are in arc transition. The thickness of the connecting rib 25 is less than the thickness of the clip 21 and the thickness of the support rib 26. The inner wall of the connecting rib 25 is flush with the clip 21, or the inner wall of the connecting rib 25 protrudes from the inner wall of the support rib 26. The anti - detachment mechanism is made of plastic material. The wall thickness of the connecting rib 25 is thinned to facilitate the deformation of the connection part between the connecting rib 25 and the clip 21, thus facilitating the movement of the clip 21.
[0025] The inner wall of the annular rib 32 is provided with a plurality of convex teeth 34. The convex teeth 34 abut against the outer wall of the ferrule. By providing the convex teeth 34, it can prevent the annular rib 32 from directly contacting the outer wall of the clip 21, which is beneficial to the annular rib 32 being smoothly inserted into the cavity 23.
[0026] The inner side of the annular cover 31 is connected with a rubber ring 6. The rubber ring 6 is located above the ferrule. The rubber ring 6 is sleeved on the outer side of the tube body 1 and is tightly fitted with the outer wall of the tube body 1. By providing the rubber ring 6, it can play an anti - slip role and further reduce the risk of the tube body 1 becoming loose.
[0027] The outer wall of the tube body 1 is provided with a scale line 11. The depth of the tube body 1 inserted into the patient's body can be observed according to the scale line 11, which is convenient for the intubation operation. And after fixation, it can be known whether the catheter 1 becomes loose by observing the scale line 11.
[0028] The above - mentioned is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above - mentioned embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
