Detailed Description

Example 1: an auxiliary expansion sleeve for transnasal intubation, as shown in figure 1 and figure 2, comprises a membrane tube 1, a slide bar 2, an elastic air bag 3 and an inflation and deflation tube 4.

Wherein, the membrane tube 1 adopts a non-elastic membrane column tube with good toughness, such as a silica gel or a resin membrane. The sliding rod 2 is a rod with a smooth surface and can have smooth dredging capability at least in a lubricating state. Each slide bar 2 is also flexible and able to bend. As shown in FIG. 3, four sliding rods are uniformly distributed and fixed on the inner wall of the thin film column tube.

The elastic air bag 3 is fixed on the outer surface of the film column tube in a sleeved mode, and the outer end of the elastic air bag is connected with an inflation and deflation tube 4. As shown in figure 4, when the elastic air bag is in a abandoning state, the elastic air bag has an automatic contraction function, thereby being capable of being attached to the outer surface of the membrane tube 1 and having small volume. Meanwhile, by utilizing the characteristic that the sliding rod gives up contraction, the sliding rods can be automatically gathered to be contracted inwards. As can be seen in the figure, the inflation and deflation pipes 4 are parallel along the film column pipe, and the inflation and deflation pipes 4 are further connected with inflation and deflation nozzles after extending outwards.

When the component is in a contracted state as shown in fig. 4, the component is placed in a nasal cavity, and the inflation and deflation pipe is positioned at the outer end of the nostril and is finally provided with an expansion structure to prevent the component from slipping to enter the throat. The inflated inflatable air bag is supported in the nasal cavity (the nasal cavity space is larger than the front nostril and the rear throat) as shown in fig. 1 and fig. 2, at the moment, the membrane tube 1 can be unfolded into a cylindrical tube shape under the expansion action of the elastic air bag 3, the four sliding rods 2 are driven by the unfolding of the membrane tube 1 to expand outwards to form a smooth channel, and therefore, the tracheal catheter is further inserted into the channel. Prevent the nasal cavity of the patient from bleeding caused by directly inserting the tracheal catheter.

Example 2: on the basis of example 1, a core handle with a pushing function can be used in order to facilitate the placement or removal of the member in the nasal cavity.

The mandrel shown in fig. 5 is a cross mandrel which is correspondingly matched with the four slide tubes in the embodiment 1, and the cross mandrel is sleeved in the center of the thin film column tube. As can be seen from fig. 5 and 6, the outer periphery of the cross handle is radially distributed with grooves which correspond to the plurality of slide bars 2 and can be matched and sleeved (the outer periphery of the cross handle 5 is radially distributed with grooves which correspond to the slide bars and can be matched and sleeved), and when the membrane tube is contracted, each slide bar can be positioned in the corresponding groove. The contraction of the elastic air bag 3 can further compress the membrane tube and each slide bar into the corresponding groove. At this moment, in order to improve the compression effect of the contracted elastic air bag 3, a layer of annular elastic body with stronger contraction force can be compounded on the outer surface of the elastic air bag 3, and after deflation, the annular elastic body can provide enough contraction force to promote the elastic air bag, the membrane tube and the four slide bars to contract towards the cross handle, so as to ensure that the slide bars are pressed into the grooves of the cross handle.

As shown in fig. 5, the cross-handle may be in the form of a single handle or may be connected at its outer end to a handle for ease of manipulation. It can be seen that the cross shank is also provided on its outer side with a collar 7 which can be slid axially and fixed, for example by means of a lock screw to the collar 7. The purpose of arranging the retaining sleeve 7 is to facilitate pushing the outer ends of the compressed sliding rods and to implant the components into the nasal cavity. Furthermore, a blocking sleeve can be fixed at the inner end of the cross handle, so that when the component needs to be removed, the component is retracted outside the cross handle by abandoning, the blocking sleeve at the inner end blocks each sliding rod of the component to prevent slipping, and the component is carried and pulled out completely when the cross handle is pulled out.

Example 3: based on the embodiment 2, the four grooves on the outer side of the cross handle are further designed to be changed from a minor arc 8 (the radian is less than 180 degrees) to a major arc 9 (the radian is slightly greater than 180 degrees), as shown in fig. 7. At the moment, each groove is changed into a clamping groove, the sliding rods clamped in each groove cannot automatically fall off, but the elastic air bag 3 can pull the membrane tube outwards along the radial direction under the expansion action of the elastic air bag to pull each sliding rod, so that the sliding rod is separated from the major arc groove. The embodiment is particularly suitable for compounding a layer of annular elastic body with strong contraction force on the outer surface of the elastic air bag 3, and after deflation, the annular elastic body can provide enough contraction force to promote the elastic air bag, the membrane tube and the four slide bars to contract towards the cross handle, so as to ensure that the slide bars are pressed into the grooves of the cross handle.

Example 4: on the basis of the embodiment 1, a cross handle with a pushing function is adopted, and the cross handle is sleeved in the center of a thin film column tube. Grooves which correspond to the sliding rods 2 and can be matched and sleeved are radially distributed on the periphery of the outer side of the cross handle, and the four grooves on the outer side of the cross handle are changed into an upper arc 9 (the radian is slightly larger than 180 degrees) from a lower arc 8 (the radian is smaller than 180 degrees), as shown in fig. 7. At the moment, each groove is changed into a clamping groove, and the sliding rod clamped in each groove cannot automatically fall off.

Regardless of whether the resilient bladder 3 is resilient or resilient enough to drive the rods radially outwardly out of the respective major arcuate groove, the present embodiment employs a mechanism that actively drives the rods out of the grooves.

As shown in fig. 8 and 9, an axial center square hole 10 is provided in the axial direction of the core shank, and an axial center square pipe 12 is fitted in a matching manner. As can be seen from fig. 10 and 11, the position of the axial square hole 10 corresponding to the corresponding groove is provided with an ejection hole 11, and the ejection holes of the corresponding group are staggered with the ejection holes of the adjacent group, or the positions of the ejection holes are staggered in sequence. As can be seen from fig. 8, the side surfaces of the periphery of the axis square tube 12 are provided with outward curled elastic pieces 13, and each elastic piece 13 corresponds to the number and position of each ejection hole 11. Before use, the axis square tube 12 is inserted into the axis square hole of the cross handle, and each elastic sheet is ensured to be compressed by the inner wall of the cross square hole. The cross handle in this case functions as in example 2 and the embodiment described above, and is used to push and remove the collapsible sleeve member. However, after the collapsible sleeve component is pushed into the nasal cavity, the axis square tube is pulled outwards and taken out, and in the process of taking out the axis square tube outwards, the elastic sheets 13 which are distributed transversely and longitudinally and are positioned on the outer side of the axis square tube sequentially enter the corresponding pop-up holes 11 and pop-up the corresponding slide bars in the grooves of the pop-up holes. After the axis square tube is taken out, the axis square tube can be used for the second time and can be inserted into the cross handle by a proper depth along the inner end of the cross handle.
