[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0023] like Figure 1 As shown, a cavity gel coupling agent applicator includes an interface structure 1 and an insertion structure 2; one end of the interface structure 1 is connected to one end of the insertion structure 2; the insertion structure 2 includes a groove 3, a transition channel, a first through hole 4, and a second through hole 5; the surface of the insertion structure 2 is provided with a groove 3; the first through hole 4 is provided on the surface of the groove 3; the transition channel is embedded in the interior of the insertion structure 2; one end of the transition channel is the second through hole 5, which is located at the end of the transition channel away from the interface structure 1.
[0024] The insertion structure 2 is shaped like a frustum and has an overall length of 36mm. The end of the insertion structure 2 closest to the interface structure 1 is the root, and the end furthest from the interface structure 1 is the top. The outer diameter of the insertion structure 2 gradually decreases from the root to the top, with the outer diameter of the root set at 8.5mm and the outer diameter of the top set at 6.8mm.
[0025] The surface of the insertion structure 2 is provided with a groove 3, the length of which is 30mm. The surface of the insertion structure 2 can have one groove 3 or multiple grooves 3 evenly distributed. For the case of multiple grooves 3, please refer to [link to relevant documentation]. Figure 2The plurality of through holes one 4 are equidistantly arranged on the surface of the groove 3; the aperture size of the through hole one 4 near the root is smaller than that of the through hole one 4 near the top; if three through holes one 4 are arranged on the groove 3, the aperture sizes of the three through holes one 4 can be set as 2mm, 1.5mm and 1mm or 2mm, 1.5mm and 1.5mm, and the aperture size of the through hole two 5 is set as 2mm; if three through holes one 4 are arranged on the groove 3, the aperture sizes of the three through holes one 4 are set as 3mm, 2mm and 1mm or 3mm, 1mm and 1mm, and the aperture size of the through hole two 5 is set as 3mm; that is, the aperture ratio of the through hole one 4 near the top and the through hole two 5 is 1:1, and the aperture of the through hole one 4 at the middle position and the through hole one 4 near the root gradually decreases or has the same aperture. The aperture size of the through hole one 4 near the top and the through hole two 5 is 1:1, and the aperture size of the other through hole one 4 is smaller than that of the through hole one 4 near the top, which facilitates the simultaneous application of the gel coupling agent inside the cavity.
[0026] The transition channel penetrates the insertion structure 2 in the direction from the top to the root of the insertion structure 2.
[0027] The through hole one 4 arranged on the groove 3 is connected with the transition channel.
[0028] One end of the groove 3 is flush with the top of the insertion structure 2.
[0029] The end of the interface structure 1 away from the insertion structure 2 is provided with internal threads, the outer diameter of the screw hole is set as 15mm, and the inner diameter is set as 10mm; the internal threads of the screw hole are screwed and docked with the screw hole of the gel coupling agent container.
[0030] After the interface structure 1 and the gel coupling agent container are fixed by screwing, the insertion structure 2 is inserted into the cavity, and the outer wall of the insertion structure 2 is in contact with the mucosa. The mucosa has softness and can wrap around the outer periphery of the insertion structure 2. The groove 3 is less compressed by the mucosa of the cavity, and can circulate air and release the gel coupling agent. The gel coupling agent flows to the groove 3 through the through hole one 4, and the gel coupling agent releases the gel coupling agent along the groove 3 in the part of the insertion structure 2 inserted.
[0031] When the gel coupling agent is extruded into the cavity through the insertion structure 2, the extrusion pressure during operation can be considered as substantially constant, but the resistance generated by the mucosa tissue wrapping at the cavity entrance varies, especially for the cavity entrance such as the anus, the mucosa muscle is prone to be in a tense state due to the involuntary anal contraction of the human body, so that the local resistance increases. The insertion structure 2 of the utility model reasonably sets the aperture specification of the through hole one 4, so that the gel coupling agent is preferentially released from the through hole two 5 at the top and the through hole one 4 near the top under the action of the extrusion pressure, and the lubrication of the cavity entrance area is quickly realized; with the continuous insertion of the insertion structure 2 into the cavity and the maintenance of the extrusion pressure, the gel coupling agent is gradually released from the through hole two 5 at the top, the through hole one 4 near the top, the through hole one 4 at the middle and the through hole one 4 at the root which have been inserted into the cavity in sequence, and finally a uniform and comprehensive gel coupling agent covering layer is formed on the inner wall of the whole cavity, the outside of the cavity entrance and the outer peripheral section of the insertion structure 2, so that the stable lubrication effect is continuously provided during the examination process, the pain and discomfort caused by friction are effectively reduced, and the smoothness of the examination operation and the tolerance of the patient are improved.
[0032] Therefore, the cavity gel coupling agent applicator can solve the problems of the existing technology that the internal and external cavity cannot be considered, the application is uneven, and the lubrication is insufficient.
[0033] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model and not to limit them, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can still be modified or replaced, and these modifications or replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the utility model.
