Detailed Description
In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.
As shown in fig. 1 to 8, the trial blocking device for the tracheotomy tube according to the utility model comprises a plugging part 1 and a cap part 2, wherein the plugging part 1 is cylindrical, the cap part 2 is integrally connected to the upper end of the plugging part 1, the diameter of the cap part 2 is larger than that of the plugging part 1, and an operating handle 3 is further integrally connected to the cap part 2; the lower part of the plugging part 1 is provided with a connecting port 11, a strip-shaped side hole 12 communicated with the connecting port 11 is formed on the side wall of the plugging part 1, the length direction of the strip-shaped side hole 12 is along the axial direction of the cylindrical plugging part 1, and the plugging part 1 can be partially or completely plugged into the opening 110 of the tracheotomy tube 100 so as to adjust the ventilation area of the strip-shaped side hole 12 exposed out of the opening 110 of the tracheotomy tube 100.
In this way, according to the blockage test device for the tracheotomy tube, when in use, the plugging part 1 of the blockage test device is plugged into the opening 110 of the tracheotomy tube 100, and the outer side wall of the plugging part 1 is tightly abutted against the inner wall of the tracheotomy tube 100, so that the positions of the plugging part and the tracheotomy tube are relatively fixed. Because the side part of the plugging part 1 is provided with the strip-shaped side hole 12, the outside air enters the plugging part 1 from the side hole and smoothly enters the tracheotomy tube 100 through the connecting port 11, and the size of the ventilation area of the strip-shaped side hole 12 exposed out of the tracheotomy tube 100 and exposed out of the opening 110 is adjusted according to the depth of the plugging part 1 extending into the opening 110 of the tracheotomy tube 100, so that the trial plugging degree is adjusted.
By arranging the operating handle 3, the plugging part 1 can be conveniently pulled out. The diameter of the cap part 2 is larger than the outer diameter of the plugging part 1, namely the outer diameter of the cap part 2 is larger than the opening 110 of the tracheotomy tube 100, so that the risk that the trial plugging device falls into the tracheotomy tube 100 is avoided. When the insertion section 1 is inserted into the opening 110, the cap section 2 limits the maximum insertion depth of the insertion section 1. Preferably, the cap 2 is arranged coaxially with the plug-in part 1, and the lower surface of the cap 2 is formed with an annular abutting step 21 located on the periphery of the plug-in part 1. The annular abutting step 21 abuts against the outer edge of the opening 110 of the tracheotomy tube 100, so that the maximum plugging depth of the plugging portion 1 is limited.
The plug-in part 1, the cap part 2 and the operating handle 3 are of an integrally formed integral structure, the components are simple, extra assembly is not needed during manufacturing, and the production and the use are very convenient. Preferably, the plugging part 1, the cap part 2 and the operating handle 3 are integrally formed by plastic or silica gel. The plastics material can be environmental protection polymer elastomer (TPE) material, and this kind of material is relatively flexible, is favorable to getting into the tracheal cannula, and can increase frictional force, reduces and deviates from the chance.
Preferably, the lower end edge of the insertion part 1 is provided with a tapered guide part 121. Preferably, the connection part of the strip-shaped side hole 12 and the lower edge of the inserting part 1 is provided with an arc-shaped chamfer 122. By providing the tapered guide portion 121, the lower end of the insertion portion 1 has a guide portion with a smaller lower portion and a larger upper portion, which facilitates the insertion portion 1 to enter the opening 110 of the tracheotomy tube 100. Set up arc chamfer 122 and convex linkage segment 123 on the bar side opening 12 for the portion of inserting is the better transition of turn department between being on 1, facilitates the use and manufactures.
The outer wall of the plugging portion 1 is in abutting connection with the inner wall of the opening 110 of the tracheotomy tube 100, and preferably, an abutting strip 13 for abutting against the inner wall of the tracheotomy tube 100 is formed on the outer wall of the plugging portion 1 in a protruding manner. The abutting strip 13 is abutted against the inner wall of the opening 110 of the tracheotomy tube 100, so that the friction force for supporting the weight of the trial blocking device is ensured between the outer wall of the plugging part 1 and the inner wall of the opening 110 of the tracheotomy tube 100, and the position can be easily adjusted by moving under the external force provided by a user. Since the height of the propping-up strip 13 protruding from the outer wall of the plugging portion 1 is small, the gap between the outer wall of the plugging portion 1 and the inner wall of the opening 110 of the tracheostomy tube 100 is controlled within a reasonable range during manufacturing.
Preferably, the operating handle 3 is provided with an anti-slip bump 311. When the user's finger pinches the operating handle 3, the anti-slip bumps 311 reduce the risk of finger slipping, so that the operation is safer and more convenient.
Preferably, the operation handle 3 includes a hand-held portion 31 and a connecting portion 32, the hand-held portion 31 is connected to the cap portion 2 through the connecting portion 32, and the anti-slip protrusions 311 are formed on the hand-held portion 31. Further, the connecting portion 32 is provided with an easy-to-break structure 321, the hand-held portion 31 can rotate on the cap portion 2 through the easy-to-break structure 321, and a rotation axis of the hand-held portion 31 is perpendicular to a normal direction of an upper surface of the cap portion 2. In this way the connection 32 can be made smaller, reducing the material used. The frangible structures 321 are similar to the connection between the flip-up cap and the cap of the shampoo, and can rotate with each other but are connected together and are resistant to tension. Through setting up easy structure 321, after the stifled ware of examination packing or installing on tracheotomy sleeve 100's opening 110, the handheld arm can rotate, reduces the length that stretches out along the stifled ware axial of examination. Thus mounted on the tracheotomy tube 100 of the patient, the hand-held portion 31 is less accessible to foreign objects, thereby reducing the risk of accidentally triggering the depth of the insertion portion 1 within the opening 110.
Furthermore, a single plug testing device can be independently packaged in a sterile packaging bag, and the packaging bag is torn open to take out the plug testing device for use when the plug testing device is required to be used.
Preferably, the strip-shaped side hole 12 has two side edges 124 parallel to the axis of the stuffing part 1, the width of the strip-shaped side hole 12 between the two side edges 124 is equal, the upper end of the strip-shaped side hole 12 is provided with a circular arc-shaped connecting section 123, and the circular arc-shaped connecting section 123 connects the two side edges 124 of the strip-shaped side hole 12.
The width of the strip-shaped side hole 12 between the two side edges 124 is equal, and the ventilation area of the strip-shaped side hole 12 outside the opening 110 of the tracheostomy tube 100 is approximately linearly related to the depth of the plugging part 1 extending into the opening 110, so that the adjustment by an operator is more convenient. Furthermore, an indication scale can be arranged on the side of the plugging part 1 to assist in adjusting the depth of the plugging part 1 extending into the opening 110.
Compared with the prior art, the trachea incision cannula has the advantages that the plugging part 1, the cap part 2 and the operating handle 3 are arranged to form a whole, the ventilation degree is adjusted according to the position of the strip-shaped side hole 12 at the side part of the plugging part 1 in the opening 110 of the trachea incision cannula 100, and the trachea incision cannula is convenient to operate.
The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
