Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a medical fixing device suitable for connecting a tracheal cannula and an oxygen tube. Background Art

[0002] Tracheotomy is to cut open the cervical trachea and insert a metal tracheal tube or a silicone tracheal tube. It is a common surgery to relieve dyspnea caused by laryngeal origin, respiratory dysfunction or lower respiratory tract secretion retention. One end of the tracheal tube is inserted into the human trachea, and the other end is exposed outside the human body to connect to the oxygen tube to supply oxygen to the patient.

[0003] In the prior art, after the oxygen tube is inserted into the tracheal cannula, the inserted end of the oxygen tube is easily dislodged from the tracheal cannula due to the fact that the outer diameter of the oxygen tube is smaller than the inner diameter of the tracheal cannula and the insertion length is limited. In order to prevent the oxygen tube from dislodging, medical staff generally bend the inserted oxygen tube and then use a rubber band to bind the oxygen tube and the tracheal cannula. However, this will bend the oxygen tube on the one hand and cause the insertion end of the oxygen tube to have a certain elastic force on the other hand. Therefore, during the patient's breathing, the insertion end of the oxygen tube may sometimes pop out of the tracheal cannula, affecting the normal oxygen supply to the patient.

[0004] In summary, a medical fixing device suitable for connecting a tracheal cannula and an oxygen tube is provided. Summary of the invention

[0005] Therefore, in order to solve the problems existing in the above-mentioned prior art, the utility model provides a medical fixing device suitable for connecting a tracheal cannula and an oxygen tube.

[0006] The utility model discloses a medical fixing device, comprising a ferrule and an inverted L-shaped anti-slipping portion. The ferrule is sleeved on an oxygen tube, and the oxygen tube and the anti-slipping portion form a ∩-shaped clamping groove.

[0007] The ferrule and the oxygen tube are in interference fit.

[0008] The inner diameter of the ferrule is consistent with the outer diameter of the oxygen tube.

[0021] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1 As shown, this embodiment discloses a medical fixing device, including a ring and an inverted L-shaped anti-detachment portion, the ring is sleeved on the oxygen tube, and the oxygen tube and the anti-detachment portion form a ∩-shaped groove.

[0025] The medical fixing device described in this embodiment has a simple structure and is easy to use. When in use, the loop is put on the oxygen tube, and then the oxygen tube is inserted into the tracheal tube, so that the side wall of the tracheal tube is clamped in the ∩-shaped clamping groove formed by the oxygen tube and the anti-detachment part, so that the oxygen tube can be quickly fixed without popping out or falling off, thereby ensuring normal oxygen supply to the patient.

[0026] The ferrule and the oxygen tube are in interference fit, that is, when the ferrule can be normally sleeved, the inner diameter of the ferrule can be slightly smaller than the outer diameter of the oxygen tube.

[0027] The inner diameter of the ferrule is consistent with the outer diameter of the oxygen tube.

[0028] The gap between the outer wall of the oxygen tube and the inner wall of the anti-detachment part is equal to the wall thickness of the tracheal tube; thus, the ∩-shaped groove formed by the oxygen tube and the anti-detachment part can just clamp the side wall of the tracheal tube, thereby fixing the oxygen tube.

[0029] The medical fixing device is made of medical PVC material.

[0030] The length of the medical fixing device is 1.5-2 cm. In this embodiment, the length of the medical fixing device is preferably 1.5 cm, that is, the length of the anti-detachment portion is 1.5 cm, and the thickness of the ring is 1 cm, so that there is a larger contact surface between the oxygen tube and the medical fixing device, making it more difficult for the oxygen tube to fall out or loosen after being fastened (i.e. fixed).

[0031] The vertical side of the anti-slip portion is arc-shaped, and its curvature is not greater than 30°; a certain curvature is set so that the inner side wall of the anti-slip portion and the outer side wall of the tracheal tube form an arc surface contact to prevent relative sliding between them.

[0032] The medical fixation device is integrally formed; it is simple to manufacture, suitable for mass production, and has low production cost.

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
