Detailed Description

As shown in fig. 1-4, a bottle cap type tracheal cannula plugging device, comprising a plugging cap 1, a connecting piece 2 and a sleeve ring 3, wherein one end of the connecting piece 2 is connected with the cap opening edge of the plugging cap 1, and the other end is connected with the sleeve ring 3. The plugging cover 1 is in a round cover shape, the outer part of the plugging cover is cylindrical, the inner part of the plugging cover is hollow, the lower end face of the plugging cover is communicated with the inner part of the plugging cover, and the upper end face of the plugging cover is a closed face. The inner diameter of the blocking cover 1 is matched with the outer diameter of the tracheal cannula and is used for covering the mouth of the tracheal cannula to block the mouth of the cannula. The lantern ring 3 is circular, and its internal diameter and tracheal cannula's external diameter looks adaptation, lantern ring 3 is used for the cover to establish in tracheal cannula's neck department. The plugging cover 1 and the lantern ring 3 are both made of elastic materials.

The use of bottle lid formula tracheal cannula plugging device as follows, when needs shutoff patient's tracheal cannula, use this plugging device. When the tracheal cannula fixing device is used, the lantern ring 3 is firstly unfolded, the lantern ring 3 is sleeved from the tube orifice end of the tracheal cannula, moves to the tube neck after penetrating through the tube orifice end, the lantern ring 3 is loosened, the lantern ring 3 automatically retracts under the action of self elasticity, and the fixing is realized outside the tube neck of the tracheal cannula in a tightening manner. Then, the lower end edge of the blocking cover 1 is opened, the lower end of the blocking cover 1 is sleeved at the pipe opening of the tracheal cannula, so that the blocking cover 1 covers the pipe opening like a bottle cap, the pipe opening of the tracheal cannula is blocked, and the tracheal cannula is blocked.

The utility model discloses a lantern ring 3 is fixed on the tracheal cannula, closes with the shutoff mouth of pipe on tracheal cannula's the mouth of pipe through 1 lids of shutoff lid, the utility model discloses can effectively shutoff tracheal cannula, have simple structure, convenient to use, the leakproofness is good, the security is high, stifled pipe is easy successful, stifled pipe process is difficult for droing, stifled effectual advantage of managing. The utility model discloses a lantern ring 3 and plugging cover 1 are the cover and establish the outside structure of tracheal cannula, utilize the characteristic of elastic material deformability simultaneously for this plugging device can strut the cover and establish on the tracheal cannula of different specifications, and the plugging device of a size can be applicable to the tracheal cannula of various specifications commonly used clinically, need not to be equipped with the plugging device of multiple size for use, and the suitability is more extensive, and need not to look for the plugging device of corresponding size when using, and it is more convenient to use.

Further, in the present embodiment, the inner diameters of the plugging cover 1 and the collar 3 are both 10-10.5 mm. In clinical practice, the outer diameter of the tracheal tube is usually 11-14mm, and the size of the outer diameter is not greatly different. Set up the diameter of the capping 1 and the lantern ring 3 into as above size for lantern ring 3 and capping 1 rely on the elastic deformation of self can grow to enough cover to establish outside the trachea cannula after strutting hard, and can resume deformation after removing external force, rely on the inseparable cover of self elasticity to establish on the trachea cannula, enable 3 covers of lantern ring to establish firmly, the capping of capping 1 is inseparable, be difficult for droing.

Furthermore, in this embodiment, rubber or silica gel material is selected for use to the elastic material, and rubber and silica gel all have good elasticity and plasticity, and the atress can take place to deform, can strut with the cover establish on the tracheal cannula of different external diameters, tighten outside tracheal cannula through self elasticity simultaneously, keep the gas tightness of stifled pipe.

Further, in this embodiment, please refer to fig. 4 in detail, an inner side surface of a rim of the plugging cover 1 is a slope, and the slope is inclined to an end surface of the plugging cover 1 and faces to a center of the plugging cover 1. This slope surface structure of slope makes the flap border department of shutoff lid 1 approximately be uncovered form, and this structure can make 1 lids of shutoff lid close when tracheal cannula's mouth of pipe department easier.

Further, in the present embodiment, referring to fig. 3 in detail, a pair of outer ears 4 are symmetrically disposed outside the blocking cover 1, the outer ears 4 are connected to the outer peripheral surface of the blocking cover 1, and the outer ears 4 are made of hard plastic. In the in-service use process, because the shutoff lid 1 is soft elastic material, and its size is less, it is comparatively difficult when strutting the flap border of shutoff lid 1, especially after shutoff lid 1 lid closes on the mouth of pipe, receive the influence of relative frictional force between shutoff lid 1 and the trachea sleeve pipe, take off of shutoff lid 1 comparatively difficult. Therefore, a pair of external ears 4 made of hard materials are symmetrically arranged at the edges of the two sides of the blocking cover 1, the external ears 4 can apply force to the two sides to open the blocking cover 1, and the blocking cover 1 is covered at the opening of the tracheal cannula. When removing the closure cap 1, the force can also be applied to the closure cap 1 by pushing the outer ear 4 outwards, pulling the closure cap 1 outwards. The outer ear 4 facilitates the force application by the operator and the pulling out and closing operation of the plugging cover 1.

Furthermore, in this embodiment, the outer ear 4 is in a circular arc shape and is attached to the outer contour of the blocking cover 1, so that the outer ear can be conveniently connected to the outer edge of the blocking cover 1. All be equipped with anti-skidding line 41 on the tow sides of auricle 4, it is specific, anti-skidding line 41 is rectangular form, and many anti-skidding lines 41 are along the equidistant range of the camber line direction of auricle 4. The anti-slip lines 41 can increase the friction force between the hand and the surface of the external ear 4, and can prevent the hand from slipping in the force application process.

Further, in this embodiment, the connecting piece 2 is the plastic tape, and the plastic tape is long banding for connect shutoff lid 1 and lantern ring 3, make in tracheal cannula shutoff process, when taking off shutoff lid 1 temporarily, shutoff lid 1 accessible plastic tape hangs on lantern ring 3, prevents that shutoff lid 1 from losing.
