Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to a gynecological self-service vaginal applicator. Background Art

[0002] Vaginal administration is a route of drug administration that directly applies drugs into the vagina. Pharmacologically, administering drugs in this way to the vagina or nearby structures has its potential advantages. The drugs mainly act on the vagina or nearby structures (such as the cervix), and its adverse reactions are also smaller than those of other routes of administration. Therefore, it is widely used in clinical medicine.

[0003] Currently, when performing vaginal drug administration treatment, usually a disposable rinser is filled with the liquid medicine, and then it is introduced into the vagina and squeezed to administer the drug. The drug needs to be taken out in advance and placed on the input device. The applicator is aligned with the patient's vaginal orifice, and the applicator is inserted into the vagina until the target position, and then the action of injecting or pushing the drug is started, so that the drug can directly reach the patient's body, reducing the loss of the drug. And this method is easy to operate, and at the same time is suitable for the patient to use by himself, which better meets the patient's privacy psychology and helps the development of the treatment.

[0004] However, in the actual use process of the above-mentioned device, the patient needs to have a certain amount of medical knowledge by himself. At the same time, due to the different body structures of patients, it is not simply a straight entry. This makes it possible that during the insertion of the applicator into the vagina, due to the patient's own nervousness or pain, the direction may need to be fine-tuned. And the applicator itself lacks a positioning structure, and it is very easy to cause greater harm to the patient's vagina due to the patient's nervous shaking hands. In view of this, we have proposed a gynecological self-service vaginal applicator. Summary of the Invention

[0005] The purpose of the present invention is to provide a gynecological self-service vaginal applicator to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A gynecological self-service vaginal applicator, including a positioning plate. An arc-shaped contact groove is opened at the end of the positioning plate, a drug administration cavity is opened at the center of the positioning plate, and a guiding component is arranged inside the positioning plate. The guiding component includes:

[0007] A rotating ring, the inner wall of the positioning plate is rotatably installed with a rotating ring, the end of a rotating rod is rotatably installed on the inner wall of the rotating ring, the rotating rod penetrates through a guiding wheel, and the guiding wheel is fixedly connected to the rotating rod. Contact bumps are fixedly installed on the arc-shaped outer wall of the guiding wheel;

[0008] A transmission cylinder, the side wall of the rotating ring is fixedly connected to the end of the transmission cylinder, and the end of a first volute spring is fixedly connected to the arc-shaped outer wall of the transmission cylinder.

[0009] Preferably, two sets of arc-shaped contact grooves are provided, and the two sets of arc-shaped contact grooves are mirror-symmetrically arranged on the left and right sides of the positioning plate. A silica gel pad is arranged in the groove of the arc-shaped contact groove to prevent the arc-shaped contact groove from causing excessive irritation to the patient's legs, thereby affecting the patient's use. At the same time, due to the relatively large frictional force of the silica gel pad itself, the positioning plate will not easily shift after being clamped by the legs.

[0010] Preferably, a receiving cavity is formed inside the positioning plate, and the sizes of the receiving cavity are adapted to those of the rotating ring and the transmission cylinder to facilitate the rotation of the rotating ring and the transmission cylinder inside the receiving cavity. In addition, a circular hole is formed at the connection between the receiving cavity and the drug delivery cavity to facilitate the guiding wheel to extend from the circular hole into the drug delivery cavity, so as to clamp and position the drug delivery device passing through the drug delivery cavity.

[0011] Preferably, an arc-shaped groove concave toward the center of the guiding wheel is formed on the arc-shaped outer wall of the guiding wheel, and a rubber sleeve is arranged on the outer surface of the arc-shaped groove so as to ensure the grasping force of the guiding wheel on the outer wall of the drug delivery device when the guiding wheel contacts the outer wall of the drug delivery device.

[0012] Preferably, a plurality of contact bumps are provided, and the plurality of contact bumps are evenly distributed in a circumferential array on the arc-shaped outer wall of the guiding wheel. The contact bumps are arranged at the lowest point of the arc-shaped groove, so that when the arc-shaped groove contacts the outer wall of the drug delivery device, the contact bumps can further prevent the drug delivery device from slipping.

[0013] Preferably, a protection mechanism is arranged inside the rotating ring. The protection mechanism includes a contact cavity. The inner wall of the rotating ring is provided with the contact cavity. An arc-shaped convex block is fixedly installed on the arc-shaped inner wall of the contact cavity. A hinge seat is fixedly installed on the arc-shaped outer wall of the rotating rod. The end of a connecting rod is fixedly installed on the side wall of the hinge seat. The connecting rod penetrates through a contact plate, and the contact plate is rotatably connected to the connecting rod. The end of a scroll spring two is fixedly connected to the arc-shaped outer wall of the connecting rod. A friction ball is fixedly installed on the side wall of the contact plate.

[0014] Preferably, circular holes with a diameter larger than the outer diameter of the scroll spring two are formed on the upper and lower outer walls of the contact plate, and the other end of the scroll spring two is fixedly connected to the inner surface of the circular hole. The scroll spring two is sleeved on the outside of the connecting rod, so that the connecting rod can always obtain a good transmission effect.

[0015] Preferably, several groups of friction balls are arranged on the left and right sides of the contact plate, and the several groups of friction balls are evenly distributed on the outer walls of both sides of the contact plate.

[0016] Preferably, an abutting component is arranged inside the guide wheel. The abutting component includes a transmission rod. The end of the transmission rod is fixedly installed on the inner wall of the guide wheel. The transmission rod penetrates through a special-shaped abutting plate, and the special-shaped abutting plate is rotatably connected to the transmission rod. The end of a scroll spring three is fixedly connected to the arc-shaped outer wall of the transmission rod. A contact strip is fixedly installed on the side wall of the special-shaped abutting plate, and an arc-shaped groove is formed on the outer wall of the contact strip.

[0017] Preferably, the contact strip is arranged on the side of the special-shaped abutting plate close to the outer wall of the guide wheel. When the guide wheel rotates and contacts the applicator, the special-shaped abutting plate abuts against the applicator, and the contact strip tightly adheres to the outer wall of the applicator.

[0018] Compared with the prior art, the present invention provides a gynecological self-service vaginal applicator, which has the following

[0019] Beneficial effects:

[0020] 1. For this gynecological self-service vaginal applicator, in order to avoid damage to the patient caused by the up and down offset of the applicator due to the patient's nervousness or pain during the administration process, a guiding component is provided, which cooperates with the guide wheel and the contact bumps to provide a stable support and positioning environment for the insertion of the applicator. And through the setting of the scroll spring one, it is ensured that the transmission cylinder can maintain good stability during operation, avoiding excessive deflection of the guide wheel along with the rotating ring, so as to prevent excessive angular offset of the applicator in the vertical direction, which affects the pain caused to the patient when the applicator extends into the vagina, and improves the patient's experience during the treatment process.

[0021] 2. For this gynecological self-service vaginal applicator, in order to avoid damage to the vagina caused by the patient inserting the applicator too fast during self-service treatment, a protection mechanism is provided. As the applicator extends, the guide wheel will rotate, thereby driving the rotating rod to rotate. At this time, under the elastic force of the scroll spring two, the contact plate will not block the rotation of the rotating rod, and with the cooperation of the friction ball, the arc-shaped convex block can inhibit the rotation speed of the rotating rod, so that the patient will not insert the applicator into the vagina too fast during the process, ensuring the stable input of the applicator and thus avoiding damage to the patient.

[0022] 3. For this gynecological self-service vaginal applicator, in order to ensure the grasping force of the guide wheel on the applicator and avoid danger caused by the separation between the applicator and the guide wheel, an abutting component is provided. When the guide wheel rotates and contacts the applicator, the special-shaped abutting plate abuts against the applicator, and the contact strip tightly adheres to the outer wall of the applicator, effectively avoiding the situation that the applicator is offset or separated from the guide wheel during the insertion process, thereby ensuring the safe insertion of the applicator and ensuring the patient's use experience and safety.

DETAILED DESCRIPTION OF THE INVENTION

[0030] As Figures 1-6 shown, the present invention provides a technical solution: a gynecological self-service vaginal applicator, including a positioning plate 1, an arc contact groove 2 is opened at the end of the positioning plate 1, a drug delivery cavity 3 is opened at the center of the positioning plate 1, a guiding component is arranged inside the positioning plate 1, the guiding component includes a rotating ring 4, the rotating ring 4 is rotatably installed on the inner wall of the positioning plate 1, the end of a rotating rod 5 is rotatably installed on the inner wall of the rotating ring 4, the rotating rod 5 penetrates through a guide wheel 6, and the guide wheel 6 is fixedly connected to the rotating rod 5, contact bumps 7 are fixedly installed on the arc-shaped outer wall of the guide wheel 6, the end of a transmission cylinder 8 is fixedly connected to the side wall of the rotating ring 4, and the end of a first scroll spring 9 is fixedly connected to the arc-shaped outer wall of the transmission cylinder 8.

[0031] In one embodiment of the present invention, there are two groups of arc-shaped contact grooves 2, and the two groups of arc-shaped contact grooves 2 are mirror-imaged on the left and right sides of the positioning plate 1, so that the arc-shaped contact grooves 2 can be better placed at the patient's vaginal opening, and the positioning plate 1 can be clamped by the patient's legs. Specifically, a silicone pad is arranged in the groove of the arc-shaped contact groove 2 to prevent the arc-shaped contact groove 2 from causing excessive stimulation to the patient's legs, thereby affecting the patient's use. At the same time, due to the large friction of the silicone pad itself, the positioning plate 1 will not be easily displaced after being clamped by the legs, thereby ensuring that the patient can ensure high safety when administering the drug. Furthermore, the drug administration cavity 3 is arranged At the center of the positioning plate 1, it is more convenient to insert the drug delivery device through the drug delivery cavity 3 into the patient's vaginal opening, so that the patient can better find the position when using it by himself, thereby improving the safety and convenience of drug delivery. At the same time, a accommodating cavity is provided inside the positioning plate 1, and the interior of the accommodating cavity is adapted to the size of the rotating ring 4 and the transmission cylinder 8, so as to facilitate the rotation of the rotating ring 4 and the transmission cylinder 8 inside the accommodating cavity. In addition, a circular hole is provided at the connection between the accommodating cavity and the drug delivery cavity 3, so as to facilitate the guide wheel 6 to extend from the circular hole into the interior of the drug delivery cavity 3, thereby clamping and positioning the drug delivery device passing through the drug delivery cavity 3, so as to achieve a protective effect on the drug delivery device.

[0032] In an embodiment of the present invention, the inner diameter of the rotating ring 4 is greater than the outer diameter of the guide wheel 6, so that the guide wheel 6 can freely rotate in the inner annular cavity of the rotating ring 4 without causing problems of movement interference with the rotating ring 4. At the same time, an arc-shaped groove recessed toward the center of the guide wheel 6 is provided on the arc-shaped outer wall of the guide wheel 6, and a rubber sleeve is provided on the outer surface of the arc-shaped groove. When the guide wheel 6 contacts the outer wall of the applicator, it can ensure the grasping force of the guide wheel 6 on the applicator, avoiding accidental and rapid insertion of the applicator into the vagina during the patient's use of the applicator, which may cause harm to the patient's vagina. In addition, a number of contact bumps 7 are provided, and the number of contact bumps 7 is evenly distributed in a circumferential array on the arc-shaped outer wall of the guide wheel 6. Specifically, the contact bumps 7 are provided at the lowest point of the arc-shaped groove. When the arc-shaped groove contacts the outer wall of the applicator, the contact bumps 7 can further prevent the applicator from slipping, affecting the slow advancement of the applicator during drug delivery, and ensuring the safety of the patient during vaginal drug delivery. Further, the left end of the transmission cylinder 8 is provided as a cylinder with an inner diameter greater than the outer diameter of the guide wheel 6, and the right end of the transmission cylinder 8 is provided as a cylinder with an outer diameter smaller than the outer diameter of the rotating ring 4, so as to leave enough installation space for the first scroll spring 9 in the accommodation cavity. At the same time, the other end of the first scroll spring 9 is fixedly connected to the inner wall of the accommodation cavity, and the first scroll spring 9 is sleeved on the arc-shaped outer wall of the transmission cylinder 8, so that the first scroll spring 9 can always provide a stable transmission effect for the transmission cylinder 8, ensuring that the transmission cylinder 8 can maintain good stability during operation, avoiding excessive deflection of the guide wheel 6 along with the rotating ring 4, which may cause excessive angular deviation of the applicator in the vertical direction, affecting the pain caused to the patient when the applicator extends into the vagina, and improving the patient's experience during the treatment process.

[0033] In addition, in order to avoid harm to the vagina caused by the patient inserting the applicator too quickly during self-help treatment, a protection mechanism is provided inside the rotating ring 4. The protection mechanism includes a contact cavity 10. The inner wall of the rotating ring 4 is provided with the contact cavity 10. An arc-shaped protrusion 11 is fixedly installed on the arc-shaped inner wall of the contact cavity 10. An articulated seat 12 is fixedly installed on the arc-shaped outer wall of the rotating rod 5. The end of a connecting rod 13 is fixedly installed on the side wall of the articulated seat 12. The connecting rod 13 penetrates through a contact plate 14, and the contact plate 14 is rotatably connected to the connecting rod 13. The end of a second scroll spring 15 is fixedly connected to the arc-shaped outer wall of the connecting rod 13. A friction ball 16 is fixedly installed on the side wall of the contact plate 14.

[0034] In an embodiment of the present invention, two sets of contact cavities 10 are provided, and the two sets of contact cavities 10 are mirror - arranged on the upper and lower inner walls of the rotating ring 4. At the same time, the end of the rotating rod 5 is rotatably connected to the inner wall of the contact cavity 10 on the side away from the center of the rotating ring 4. In addition, the contact cavity 10 is arranged in a cylindrical shape. Specifically, the inner diameter of the contact cavity 10 is larger than the outer diameter of the rotating rod 5. Further, another set of friction balls 16 is arranged on the outer walls on the left and right sides of the arc - shaped convex block 11, and the number of the friction balls 16 is several, and the several friction balls 16 are evenly distributed on the outer walls on the left and right sides of the arc - shaped convex block 11. In addition, two sets of hinge seats 12 are provided, and the two sets of hinge seats 12 are arranged on the upper and lower sides of the rotating rod 5, and the distance between the two sets of hinge seats 12 is adapted to the height of the contact plate 14, so that the contact plate 14 can rotate with the connecting rod 13 as the rotation center, and the two sets of hinge seats 12 can provide support and installation effects for the contact plate 14. Further, circular holes with a diameter larger than the outer diameter of the scroll spring two 15 are opened on the outer walls on the upper and lower sides of the contact plate 14, and the other end of the scroll spring two 15 is fixedly connected to the inner surface of the circular hole. Specifically, the scroll spring two 15 is sleeved on the outside of the connecting rod 13, so that the connecting rod 13 can always obtain a good transmission effect. At the same time, several groups of friction balls 16 are arranged on the left and right sides of the contact plate 14, and the several groups of friction balls 16 are evenly distributed on the outer walls on both sides of the contact plate 14. Thus, after the guide wheel 6 contacts the applicator, as the applicator extends, the guide wheel 6 will rotate, thereby driving the rotating rod 5 to rotate. At this time, under the elastic force of the scroll spring two 15, the contact plate 14 will not block the rotation of the rotating rod 5, and with the cooperation of the friction balls 16, the arc - shaped convex block 11 can inhibit the rotation speed of the rotating rod 5, so that the patient will not have too fast a speed when inserting the applicator into the vagina, ensuring the stable input of the applicator and avoiding harm to the patient.

[0035] In addition, in order to ensure the gripping force of the guide wheel 6 on the applicator and prevent the applicator from detaching from the guide wheel 6 and causing danger, a contact - abutting component is arranged inside the guide wheel 6. The contact - abutting component includes a transmission rod 17. The end of the transmission rod 17 is fixedly installed on the inner wall of the guide wheel 6. The transmission rod 17 penetrates through a special - shaped contact plate 18, and the special - shaped contact plate 18 is rotatably connected to the transmission rod 17. The end of a scroll spring three 19 is fixedly connected to the arc - shaped outer wall of the transmission rod 17. A contact strip 20 is fixedly installed on the side wall of the special - shaped contact plate 18, and an arc - shaped groove 21 is opened on the outer wall of the contact strip 20.

[0036] In an embodiment of the present invention, a contact cavity is provided in the arc-shaped groove formed on the arc-shaped outer wall of the guide wheel 6, so that the contact assembly can be arranged in the contact cavity. This enables the contact assembly to continuously press against the outer wall of the medicator during the continuous rotation of the guide wheel 6. At the same time, the other end of the scroll spring III 19 is fixedly connected to the side wall of the special-shaped contact plate 18, so that the scroll spring III 19 can provide a stable transmission effect for the special-shaped contact plate 18. Further, the contact strip 20 is arranged on the side of the special-shaped contact plate 18 close to the outer wall of the guide wheel 6. When the guide wheel 6 rotates and contacts the medicator, the special-shaped contact plate 18 abuts against the medicator, and the contact strip 20 tightly adheres to the outer wall of the medicator. At the same time, both the contact strip 20 and the arc-shaped groove 21 are made of rubber material, so as to enhance the grasping effect of the contact strip 20 and the arc-shaped groove 21 on the medicator, effectively preventing the medicator from shifting or detaching from the guide wheel 6 during the insertion process, thereby ensuring the safe insertion of the medicator and guaranteeing the user experience and safety of the patient.

[0037] In the present invention, during use, first lay a disposable spacer. The patient places the medicine at the output end of the applicator, and the output end is a disposable applicator. Then, place the device near the vaginal orifice of the patient, and the arc contact groove 2 is contacted by the patient's legs to clamp the device. At this time, insert the applicator through the administration cavity 3 and align it with the vaginal orifice of the patient and insert it. When reaching the target position, the medicine is delivered to the target position through the output of the applicator, completing the patient's self-service vaginal administration. At the same time, in order to avoid damage to the patient caused by the up and down deviation of the applicator due to the patient's nervousness or pain during the administration process, a guiding component is provided, which cooperates with the guiding wheel 6 and the contact bumps 7 to provide a stable support and positioning environment for the insertion of the applicator. And through the setting of the scroll spring 1, it is ensured that the transmission cylinder 8 can maintain good stability during operation, avoiding excessive deflection of the guiding wheel 6 along with the rotating ring 4, resulting in excessive angular deviation of the applicator in the vertical direction, affecting the pain caused to the patient when the applicator extends into the vagina and improving the patient's experience during the treatment process. In addition, in order to avoid damage to the vagina caused by the patient inserting the applicator too fast during self-service treatment, a protection mechanism is provided. As the applicator extends, the guiding wheel 6 will rotate, thereby driving the rotating rod 5 to rotate. At this time, under the elastic force of the scroll spring 2, the contact plate 14 will not block the rotation of the rotating rod 5. With the cooperation of the friction ball 16, the arc-shaped protrusion 11 can inhibit the rotation speed of the rotating rod 5, so that the patient will not have too fast a speed when inserting the applicator into the vagina, ensuring the stable input of the applicator and thus avoiding damage to the patient. At the same time, in order to ensure the gripping force of the guiding wheel 6 on the applicator and avoid danger caused by the separation between the applicator and the guiding wheel 6, a contact component is provided. When the guiding wheel 6 rotates and contacts the applicator, the special-shaped contact plate 18 contacts the applicator, and the contact strip 20 closely adheres to the outer wall of the applicator, effectively avoiding the situation of the applicator deviating or separating from the guiding wheel 6 during the insertion process, thereby ensuring the safe insertion of the applicator and ensuring the patient's use experience and safety.

[0038] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
