[0028] As shown in the figure, a cervical canal medicine applying device comprises a sleeve 1, a medicine applying assembly 2, a supporting assembly 3, a push-pull assembly 4 and a limiting assembly 5; wherein: Figs. 1 to 3
[0029] The sleeve 1 is used to send the medicine applying assembly 2 into the cervical canal;
[0030] The medicine applying assembly 2 is used to absorb and diffuse medicine liquid, and in the initial state, the medicine applying assembly 2 is folded and collected in the sleeve 1; in use, the medicine applying assembly 2 is expanded outward and adheres to the cervical canal and cervical orifice;
[0031] The supporting assembly 3 is used to install the medicine applying assembly 2 and drive the medicine applying assembly 2 to fold and collect in the sleeve 1 or expand outward after moving out of the sleeve 1;
[0032] The push-pull assembly 4 is movably sleeved in the sleeve 1 for mounting the support assembly 3 and driving axial push-pull movement thereof;
[0033] The limiting assembly 5 is used for limiting the position of the axial movement of the push-pull assembly 4, so that the medicine applying assembly 2 is folded or unfolded under the driving of the push-pull assembly 4.
[0034] As shown in the drawings, Fig. 1 The medicine applying assembly 2 comprises foldable or unfoldable medicine cotton 21 and a medicine applying head 22 provided with a plurality of micropores, the inner side of the medicine cotton 21 is paved with an anti-seepage layer 23, the outer side of the medicine cotton 21 is paved with a permeation layer 24 for diffusing liquid medicine, and the medicine applying head 22 is installed at the center of the unfolded permeation layer 24.
[0035] The anti-seepage layer 23 is a material that cannot be permeated by liquid medicine, including soft plastic film and other materials, which prevents the liquid medicine from seeping inward and being wasted; the permeation layer 24 is a material that can be permeated by liquid medicine, including multi-layered medical gauze and microporous plastic paper, which enables the liquid medicine to seep outward and apply medicine to the cervical canal. The anti-seepage layer 23 and the permeation layer 24 can be folded in a circular manner, and can be folded by means of pre-set folds to enable the folds to "remember" the folding.
[0036] The medicine applying head 22 can be made of silica gel, and the micropores formed therein are wrapped around the periphery, so that when the medicine applying head 22 is attached to the cervical orifice, the liquid medicine can seep out of the micropores to apply medicine to the cervical orifice.
[0037] The permeation layer 24 is connected to the medicine applying head 22 by sewing, bonding or other means, so that the two are connected to form a whole, and are applied to the cervical canal and the cervical orifice to achieve good medicine application and sealing.
[0038] As shown in the drawings, Fig. 1 , 2 The push-pull assembly 4 comprises a main push rod 41 and a secondary push rod 42, the main push rod 41 is movably sleeved in the sleeve 1, the support assembly 3 is installed at the front end of the main push rod 41, the secondary push rod 42 is movably sleeved in the main push rod 41, and the front end of the secondary push rod 42 is connected to the medicine applying head 22, and the secondary push rod 42 is provided with an injection pipe 43 for injecting liquid medicine into the medicine cotton 21.
[0039] The main push rod 41 and the secondary push rod 42 can move axially, but are prohibited from rotating to avoid twisting the medicine applying assembly 2. The main push rod 41 is used to push the support assembly 3 outward, so that the support assembly 3 unfolds the medicine applying assembly 2 outward; the secondary push rod 42 is used to push the medicine applying head 22 forward by a distance, so that the outer side of the medicine cotton 21 forms a convex spherical surface outward, and the medicine applying head 22 can enter the cervical orifice.
[0040] In one embodiment, the sub-push rod 42 can also be designed as an injection tube 43, or an injection tube 43 can be separately arranged in the sub-push rod 42; the injection tube 43 is provided with a plurality of injection holes at one end of the cotton 21 (if the injection tube 43 is separately arranged, a plurality of injection holes are also provided at the end of the sub-push rod 42), so that the cotton 21 can be fully immersed in the liquid medicine; at the same time, since the medicine applying head 22 is close to the injection hole, the cotton 21 in contact with the medicine applying head 22 absorbs more liquid medicine, so that the liquid medicine can seep out of the micropores of the medicine applying head 22.
[0041] In another embodiment, the tail end of the sleeve 1 is a blind end, and in the initial state, the main push rod 41 and the sub-push rod 42 both extend out of the tail end of the sleeve 1; when the cotton 21 is expanded outward, the tail end of the main push rod 41 and the sub-push rod 42 is flush with the tail end of the sleeve 1, or still extends out of the tail end of the sleeve 1, so as to facilitate the operation of the push-pull assembly 4 to fold the medicine applying assembly 2 in the sleeve 1. Exemplarily, when the tail end of the main push rod 41 and the sub-push rod 42 is flush with the tail end of the sleeve 1, the tail end of the sleeve 1 is inwardly recessed to form an operation groove 11, so as to facilitate holding and operating the main push rod 41.
[0042] As shown in Fig. 1 , 2 The support assembly 3 includes a plurality of support rods and a support layer 31 which is umbrella-shaped after being expanded, the support rods are uniformly sleeved in the support layer 31, the end portions of the support rods are hinged to the front end of the main push rod 41, and a torsional spring which can make the support rods expand outward is arranged at the hinge point.
[0043] Specifically, the support layer 31 is made of a foldable plastic film or sheet, which is folded in a fan-shaped surface folding manner and can be folded by a pre-set fold line in a fold line "memory" manner. The support rods are made of flat iron material, which is symmetrically and uniformly distributed in the folded layer, so that the support layer 31 can be smoothly expanded outward.
[0044] Preferably, the number of support rods is preferably 4, 6 or 8, so that the support layer 31 can be symmetrically expanded.
[0045] Under the action of the torsional spring, when the support assembly 3 is pushed out of the sleeve 1, the force of the torsional spring makes each support rod expand outward along the end portion of the sleeve 1; when the support assembly 3 moves into the sleeve 1, the support rods are gradually folded to the center due to the limitation of the sleeve 1, and the support layer 31 is folded and folded according to the fold line.
[0046] As shown in Fig. 3As shown, the limiting assembly 5 includes limiting blocks 51 and limiting rings 52. The limiting blocks 51 are symmetrically installed on the outer side of the main push rod 41. The limiting rings 52 are a pair of rings, respectively installed on the inner wall of the sleeve 1 on both sides of the limiting blocks 51, and limit the movement of the limiting blocks 51 between the two limiting rings 52.
[0047] The distance limited by the limiting rings 52 is the distance between the fully retracted position of the support rod in the sleeve 1 and the farthest position of the support rod pushed out of the sleeve 1, thereby ensuring that the medicine applying assembly 2 can be fully retracted into the sleeve 1 and also fully expanded.
[0048] In one embodiment, the limiting assembly 5 further includes a limiting strip 53, which is axially installed on the inner wall of the sleeve 1 between the two limiting rings 52. The limiting strip 53 has limiting grooves 54 for the axial sliding of the limiting blocks 51, thereby limiting the rotation of the main push rod 41.
[0049] In another embodiment, the end of the limiting block 51 is provided with a limiting ball 55 connected by a spring 56, and the limiting groove 54 is provided with a positioning groove 57 in which the limiting ball 55 can be partially embedded. When the limiting block 51 moves in the limiting groove 54, the spring 56 connected to the limiting ball 55 is compressed. When it moves to the positioning groove 57, the spring 56 rebounds to make the limiting ball 55 enter the positioning groove 57. When the limiting ball 55 is embedded in the positioning groove 57, a certain force needs to be applied to make it separate from the positioning groove 57, thereby avoiding the arbitrary axial movement of the main push rod 41.
[0050] As shown, Fig. 3 The inner wall of the main push rod 41 is axially provided with a sliding groove 58, and the outer wall of the secondary push rod 42 is provided with a sliding block 59 which can slide in the sliding groove 58, thereby limiting the rotation of the main push rod 41.
[0051] In one embodiment, the two ends of the sliding groove 58 are respectively provided with an embedding groove which matches the sliding block 59 and can limit the medicine applying head 22 to the initial and final positions. When the sliding block 59 moves into the embedding groove, a certain opening needs to be applied to make the sliding block 59 separate from the embedding groove, thereby avoiding the arbitrary axial movement of the secondary push rod 42 and enabling the secondary push rod 42 to move with the main push rod 41. Exemplarily, the sliding block 59 can also be provided with a limiting ball 55 connected by a spring 56, and the embedding groove can also be provided with a groove which matches the limiting ball 55, thereby achieving the above functions.
[0052] At the same time, the outer side of the medicine cotton 21 needs to form an outward convex spherical surface, so the outward pushing axial movement distance required by the secondary push rod 42 is farther than that of the primary push rod 41; therefore, the secondary push rod 42 is designed to be longer, and the tail end thereof extends out of the primary push rod 41, so as to facilitate the pushing of the secondary push rod 42; in addition, the positions at which the two embedding grooves are arranged are just the starting and ending positions of the pushing of the secondary push rod 42, so the position of the secondary push rod 42 is accurately positioned.
[0053] As shown in Fig. 1 The medicine applying device comprises a cap 60 for protecting the medicine applying assembly 2, and the cap 60 is snap-connected to the end of the sleeve 1.
[0054] It should be noted that the medicine cotton 21, the permeation layer 24, the anti-permeation layer 23 and the support layer 31 are placed in the sleeve 1 in an orderly folded state in the initial state; when the medicine applying is completed and the medicine applying assembly 2 is collected, the folding may be disordered or unable to be orderly folded; it should be understood that as long as the folding and the collection of the medicine applying assembly 2 in the sleeve 1 can be performed, the initial orderly folding is not strictly required. At the same time, the inner side of the support layer 31 is arranged as a closed interval, so as to collect the medicine liquid flowing out of the medicine cotton 21 due to extrusion when the medicine applying assembly 2 is folded and collected.
[0055] In a preferred embodiment, the diameter of the medicine cotton 21 after the permeation layer 24 is unfolded is 3-4 cm, the outer diameter of the medicine applying head 22 is about 0.5 cm, and the total length of the sleeve 1 and the medicine cotton 21 after being unfolded is 6-7.5 cm.
[0056] In use, the vaginal speculum is used to open the vagina and expose the cervical canal (vaginal segment) and wipe off the excess secretion; the cap 60 of the medicine applying device is disassembled, the tail end of the sleeve 1 is held by hand, the sleeve 1 is inserted into the cervical canal through the vaginal speculum; the primary push rod 41 is slowly pushed forward, the support assembly 3 is gradually moved out of the front end of the sleeve 1, the support assembly 3 unfolds the medicine applying assembly 2 outward, the secondary push rod 42 is further pushed forward, until the limiting ball 55 is embedded into the positioning groove 57 at the front end and the sliding block 59 is embedded into the embedding groove at the front end, so that the permeation layer 24 of the medicine cotton 21 is attached to the cervical canal and the medicine applying head 22 is inserted into the cervical orifice; the medicine liquid is injected from the injection pipe 43 by using the syringe, the medicine liquid enters the medicine cotton 21 through the medicine injection hole and is absorbed and diffused to all positions of the medicine cotton 21, and the medicine liquid is wrapped and applied to the cervical canal and the cervical orifice through the permeation layer 24 and the medicine applying head 22; the position of the sleeve 1 is kept, and the vaginal speculum is withdrawn. After the medicine applying is completed, the position of the sleeve 1 is kept, the primary push rod 41 and the secondary push rod 42 are pulled outward, the limiting ball 55 is embedded into the positioning groove 57 at the rear end, and the sliding block 59 is embedded into the embedding groove at the rear end, so that the medicine applying assembly 2 is collected in the sleeve 1, and finally the sleeve 1 is taken out from the vagina as a whole.
[0057] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
