Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a vaginal medicine applicator for gynecological patients, which is convenient for fully applying medicine. Background Art

[0002] Vaginitis is a common gynecological disease caused by bacterial, fungal or parasitic infections. Clinical treatment often involves applying medications to the inner wall of the vagina (such as ointments, suppositories, etc.) to ensure that the medication can directly act on the affected area.

[0003] The vaginal fornix (especially the posterior fornix) is a high-incidence area for vaginal inflammation. Its anatomical position is deep and concave in an arc shape, closely adjacent to the cervix, and is deep and hidden. Such structural characteristics make it difficult for drugs to reach the deep structure of the fornix to fully cover the inflamed area, which can easily lead to poor treatment effects. In response to this, clinical practice usually adopts the method of pushing a large amount of drugs at the external os of the cervix to ensure that the drugs can fully diffuse to the deep structure of the fornix to cover the inflamed area.

[0004] However, with this mode of operation, as the amount of medicine pushed out increases, the pressure formed at the external os of the human cervix will gradually increase, and the medicine carrying pathogens may enter the uterine cavity through the cervical os, increasing the risk of endometrial infection; and, the accumulation of excessive medicine at the cervical os may cause excessive local drug concentration, irritating / damaging the cervical mucosa.

[0005] Therefore, how to prevent drugs carrying pathogens from entering the uterine cavity through the cervical os while ensuring that the drugs are fully diffused into the deep vault structure to cover the inflammatory site is a technical problem that needs to be urgently solved in the existing technology.

The blocking tube body and the isolation tube have a first matching form and a second matching form. When the blocking tube body is received in the isolation tube, the two form a first matching form; when the blocking tube body extends out of the isolation tube, the two form a second matching form. With this structural setting, before inserting the inner section of the supporting tube body into the patient's vagina, the blocking tube body and the isolation tube need to be adjusted to the first matching form, so that the blocking tube body is wrapped in the isolation tube to form a physical isolation barrier. This structure can not only effectively prevent the ointment from flowing back and contaminating the blocking tube body, but also prevent the blocking tube body from contacting the vaginal environment and being contaminated during insertion, thereby effectively avoiding pathogens and / or drugs from entering the uterine cavity and reducing the risk of endometrial infection; further, when the blocking tube body and the isolation tube are adjusted to the first matching form, the sharp front end of the blocking tube body is completely received inside the isolation tube, thus forming a progressive protection during the insertion of the instrument into the vagina, effectively reducing the risk of the tip of the blocking tube body accidentally scraping the inner wall of the vagina and / or the vaginal vault tissue; on the other hand, when the supporting tube body When the end of the internal segment abuts against the cervical ostium of the human body, the first matching form between the blocking tube body and the isolation tube is adjusted to the second matching form. In this process, the coaxially designed isolation tube and the support tube body form a natural guide track to guide the axial path of the blocking tube body, ensuring that the blocking tube body can always be aligned with the axial direction of the cervical ostium of the human body when it is extended, thereby improving the accuracy of the blocking tube body entering the cervical canal; at the same time, the accuracy of the blocking tube body entering the cervical canal of the human body is improved, and the risk of damage to the inner wall of the vagina and / or the vaginal vault tissue caused by the catheterization operation can be further reduced;

[0023] 3. The vaginal applicator device for gynecological patients which is convenient for sufficient application of medicine described in the present invention is further provided with a second blocking airbag on one side of the end of the inner section of the support tube body, the second blocking airbag is arranged around the support tube body, a first air supply channel connected with the second blocking airbag is arranged in the side wall of the support tube body, air is injected into the second blocking airbag by means of the first air supply channel to make it expand, and then the second blocking airbag can fill the matching gap between the support tube body and the human vagina; the air supply pipe includes a main air pipe and a sleeve, the main air pipe is connected to the blocking tube body, the sleeve is sleeved on the outside of the main air pipe, and the sleeve can rotate around the main air pipe; an application airbag is provided on the end of the sleeve close to the blocking tube body, and a second air supply channel connected with the application airbag is arranged on the side wall of the sleeve, and air is injected into the application airbag by means of the second air supply channel to make it expand. With this structural setting, when the first blocking airbag and the second blocking airbag are driven to move in opposite directions, the vaginal inner wall tissue is stretched through mechanical linkage to eliminate the ineffective cavities formed by the wrinkles, so that the ointment can more fully penetrate into the wrinkled cavities of the vaginal inner wall; further, during the rotation of the application airbag, the aggregated ointment can be squeezed to disperse it, thereby improving the uniformity of the ointment covering the vaginal inner wall; on the other hand, during the rolling of the application airbag, its surface is in full-circle contact with the stretched vaginal wall, and the extrusion force generated by the elastic deformation of the airbag can be used to push the ointment remaining in the vagina to the mucosal surface, thereby reducing the waste of the drug.

[0035] Example 1: Figures 1 to 3 As shown, a vaginal medicine applicator for gynecological patients that is convenient for sufficient medicine application according to the present invention comprises a support tube body 1 and a push injection component 2, wherein the support tube body 1 has an internal section and an external section, the internal section of the support tube body 1 is used to extend into the vagina of a human body, an accommodating cavity 3 is provided inside the support tube body 1, and the accommodating cavity 3 is used to store ointment for the treatment of vaginitis, and a plurality of medicine outlet holes 4 are also provided at the end of the internal section of the support tube body 1;

[0036] The push injection component 2 includes a piston block 5 and a push rod 6, the piston block 5 is clamped in the accommodating chamber 3, the push rod 6 is connected to the piston block 5, and the push rod 6 is used to push / pull the piston block 5 to slide in the accommodating chamber 3; the push rod 6 is used to push the piston block 5 to slide toward the end of the inner section of the support tube body 1, and the piston block 5 can squeeze the ointment in the accommodating chamber 3 to make it overflow from the medicine outlet 4;

[0037] A blocking tube body 7 is also provided at the end of the inner section of the support tube body 1. The outer diameter of the blocking tube body 7 is smaller than the outer diameter of the support tube body 1. The central axis of the blocking tube body 7 is arranged to coincide with the central axis of the support tube body 1. The blocking tube body 7 is used to extend into the cervical canal of the human body. A first blocking airbag 8 is also provided on the blocking tube body 7. An air supply pipe 9 is provided in the accommodating cavity 3. The air supply pipe 9 is connected to the blocking tube body 7, and the air supply pipe 9 is communicated with the first blocking airbag 8. An accommodating channel 10 is provided inside the piston block 5 and the push rod 6. The air supply pipe 9 passes through the accommodating channel 10, and the end of the air supply pipe 9 exceeds the end of the push rod 6. The air supply pipe 9 is used to inject air into the first blocking airbag 8 to form an expanded state.

[0038] The vaginal applicator for gynecological patients that is convenient for sufficient application of medicine described in the present invention is used, and the blocking tube body 7 is provided to close the external os of the human uterus. In this way, during the operation of pushing the medicine, the ointment can be prevented from flowing back into the uterine cavity under the action of pressure, effectively avoiding the risk of cervical irritation or ascending infection; further, in this embodiment, the first blocking airbag 8 is provided on the blocking tube body 7. In actual use, after the first blocking airbag 8 is expanded, it can better fill the matching gap between the blocking tube body 7 and the cervix, thereby further avoiding the ointment carrying pathogens from entering the human cervix; on the other hand, when the first blocking airbag 8 is in an expanded state, it can squeeze the tissue of the external os of the cervix, so that this part of the tissue fits with the inner wall of the vagina, and then the excess ointment in the vaginal vault can be squeezed out, avoiding the accumulation of excessive medicine in the cervical os and / or the vaginal vault, resulting in excessive local drug concentration and irritation / damage to the cervical mucosa.

[0039] Specifically, in this embodiment, when in use, the internal section of the support tube body 1 is inserted along the vagina, and when the end of the blocking tube body 7 is felt to abut against the vaginal vault and stop, the direction of the blocking tube body 7 is adjusted by rotating and / or moving the support tube body 1. When the blocking tube body 7 is aligned with the external cervical os, the support tube body 1 is slowly pushed forward to allow the blocking tube body 7 to extend into the cervical canal by about 1-2 cm.

[0040] The push rod 6 is slowly pushed to move the piston block 5 toward the end of the inner section of the support tube body 1, so that the piston block 5 squeezes the ointment in the accommodating cavity 3 to make it overflow from the drug outlet hole 4;

[0041] When the amount of the injected ointment reaches the set value, a micro air pump is connected to the exposed end of the air supply tube 9 to slowly inject air into the first blocking airbag 8 to make it gradually expand; during this process, the support tube body 1 can be rotated and / or pulled to allow the first blocking airbag 8 to fully squeeze the tissue of the external cervical os, so that this part of the tissue can fit more closely to the inner wall of the vagina, ensuring that the excess ointment in the vaginal vault can be completely squeezed out, thereby improving the uniformity of the ointment applied to the vaginal vault.

[0042] Example 2: Figures 1 to 3 As shown, the vaginal applicator for gynecological patients which is convenient for sufficient application of medicine described in the present invention is based on the above method, and further, the blocking tube body 7 and the supporting tube body 1 are independent structures; an isolation tube 11 is also arranged in the accommodating cavity 3, and the isolation tube 11 is connected to the end of the inner section of the supporting tube body 1; the central axis of the isolation tube 11 is arranged to coincide with the central axis of the supporting tube body 1, the length of the isolation tube 11 is greater than the length of the blocking tube body 7, and the inner diameter of the isolation tube 11 matches the outer diameter of the blocking tube body 7; the blocking tube body 7 and the isolation tube 11 have a first matching form and a second matching form; when the blocking tube body 7 is received in the isolation tube 11, the two form a first matching form; when the blocking tube body 7 is extended from the isolation tube 11, the two form a second matching form.

[0043] Specifically, in this embodiment, before the internal segment of the support tube body 1 is inserted into the patient's vagina, it is necessary to adjust the blocking tube body 7 and the isolation tube 11 to a first matching form, so that the blocking tube body 7 is wrapped inside the isolation tube 11 to form a physical isolation barrier. This structure can not only effectively prevent the ointment from backflowing and contaminating the blocking tube body 7, but also prevent the blocking tube body 7 from contacting the vaginal environment and being contaminated during the insertion process, thereby effectively avoiding pathogens and / or drugs from entering the uterine cavity and reducing the risk of endometrial infection; further, when the blocking tube body 7 and the isolation tube 11 are adjusted to the first matching form, the sharp front end of the blocking tube body 7 is completely received in the isolation tube 11, thus forming a progressive protection during the insertion of the instrument into the vagina, effectively reducing the risk of the tip of the blocking tube body 7 accidentally scratching the inner wall of the vagina and / or the vaginal vault tissue; on the other hand, when the support tube body 1 When the end of the internal segment abuts against the human uterine ostium, the first matching form between the blocking tube body 7 and the isolation tube 11 is adjusted to a second matching form. During this process, the coaxially designed isolation tube 11 and the support tube body 1 form a natural guide track to guide the axial path of the blocking tube body 7, ensuring that the blocking tube body 7 can always be aligned with the axial direction of the human uterine ostium when extended, thereby improving the accuracy of the blocking tube body 7 entering the cervical canal; at the same time, the accuracy of the blocking tube body 7 entering the human cervical canal is improved, and the risk of damage to the vaginal inner wall and / or vaginal vault tissue during the catheterization operation can be further reduced.

[0044] It should be noted that in this embodiment, the ointments used for the treatment of vaginal inflammation are mainly clindamycin ointment, estrogen cream, etc. Such ointments have a high viscosity. When they are stored in the accommodating cavity 3,

[0045] As a preferred embodiment, based on the above method, further, a rubber cover 12 is provided on the top of the isolation tube 11 and the end of the push rod 6, and a through hole is provided on the rubber cover 12, and the air pipe 9 passes through the through hole. The rubber cover 12 can produce elastic deformation, and when the rubber cover 12 is in a natural state, the diameter of the through hole is smaller than the outer diameter of the air pipe 9.

[0046] Specifically, the rubber cover 12 in this embodiment has a small through hole in a natural state. When the air tube 9 is inserted, the through hole will be enlarged. Due to elastic deformation, the rubber cover 12 will tightly wrap the air tube 9, thereby preventing the ointment from entering the interior of the isolation tube 11 from the gap between the air tube 9 and the through hole; and, the rubber cover 12 in this embodiment can also limit the freedom of movement of the air tube 9, reducing its radial displacement when pushing the air tube 9, thereby further improving the accuracy of the blocking tube body 7 entering the cervical canal.

[0047] As a preferred embodiment, based on the above method, further, the structural dimensions of the accommodating channel 10 in the piston block 5 match the structural dimensions of the isolation tube 11. With this structural setting, it is ensured that the piston block 5 moves to the bottom of the support tube body 1, so that the ointment in the accommodating cavity 3 can be fully pushed out, reducing the waste of ointment.

[0048] As a preferred embodiment, based on the above method, further, a second blocking airbag 14 is further provided on one side of the end of the inner section of the support tube body 1, and the second blocking airbag 14 is arranged around the support tube body 1. A first air supply channel 15 connected to the second blocking airbag 14 is provided in the side wall of the support tube body 1. Air is injected into the second blocking airbag 14 by utilizing the first air supply channel 15 to make it expand, so that the second blocking airbag 14 can fill the fitting gap between the support tube body 1 and the human vagina.

[0049] Specifically, in this embodiment, after the blocking tube body 7 is extended into the human cervix, a micro-pump is connected to the exposed end of the first air delivery channel 15, and air is slowly injected into the second blocking airbag 14 to make it gradually expand. After the second blocking airbag 14 is used to fill the matching gap between the support tube body 1 and the human vagina, the ointment is pushed into the cervical part. When the push amount reaches the set value, the air in the second blocking airbag 14 is released; then, air is slowly injected into the first blocking airbag 8 to make it expand, and the first blocking airbag 8 is used to squeeze out the excess ointment in the vaginal vault, and the application operation of the drug in the vaginal vault is completed. In this embodiment, the second blocking airbag 14 is set to fill the matching gap between the support tube body 1 and the human vagina. After the ointment overflows from the drug outlet 4, it can be confined to the external cervical part, so that the lesion area in the vaginal vault can be more fully covered by the drug, ensuring the treatment effect.

[0050] Example 3: Figure 4 As shown, the vaginal applicator device for gynecological patients which is convenient for sufficient application of medicine described in the present invention is based on the above method, and further, the air supply pipe 9 includes a main air pipe 16 and a sleeve 17, the main air pipe 16 is connected to the blocking tube body 7, the sleeve 17 is sleeved on the outside of the main air pipe 16, and the sleeve 17 can rotate around the main air pipe 16; the sleeve 17 is provided with an application air bag 18 on the end of the sleeve 17 close to the blocking tube body 7, and the side wall of the sleeve 17 is provided with a second air supply channel 19 which is connected to the application air bag 18, and the application air bag 18 is expanded by injecting air into the second air supply channel 19.

[0051] Specifically, in the present embodiment, during the operation of applying the ointment on the inner wall of the vagina, air is injected into the first blocking airbag 8 and the second blocking airbag 14 respectively, and after the two airbag structures are inflated, the ointment is pushed into the vagina, and then air is injected into the application airbag 18 to form an inflated state; a thrust is applied to the main air tube 16, and a pulling force is applied to the supporting tube body 1, so that the first blocking airbag 8 has a tendency to move toward the human uterus, and the second blocking airbag 14 has a tendency to move toward the outside of the body. In this process, the inner wall tissue of the vagina located between the first blocking airbag 8 and the second blocking airbag 14 is pulled, and then the wrinkles of the inner wall of the vagina can be stretched; then the sleeve 17 is rotated, and the sleeve 17 drives the application airbag 18 to roll on the stretched inner wall surface of the vagina, so that the ointment can fully cover the inner wall surface of the vagina.

[0052] With this structural setting, when the first blocking airbag 8 and the second blocking airbag 14 are driven to move in opposite directions, the vaginal inner wall tissue is stretched through mechanical linkage to eliminate the ineffective cavities formed by the wrinkles, so that the ointment can more fully penetrate into the wrinkled cavities of the vaginal inner wall; further, during the rotation of the application airbag 18, the aggregated ointment can be squeezed to disperse it, thereby improving the uniformity of the ointment covering the vaginal inner wall; on the other hand, during the rolling of the application airbag 18, its surface is in full-circle contact with the stretched vaginal wall, and the extrusion force generated by the elastic deformation of the airbag can be used to push the ointment remaining in the vagina to the mucosal surface, thereby reducing the waste of medicine.

[0053] As a preferred embodiment, based on the above method, further, the surfaces of the first blocking airbag 8 and the second blocking airbag 14 are set to a rough surface structure. With this structural setting, the friction between the first blocking airbag 8 and the second blocking airbag 14 and the inner wall of the human vagina can be increased, so that when the inner wall tissue of the human vagina is stretched, the risk of accidental sliding of the first blocking airbag 8 and the second blocking airbag 14 can be reduced, thereby improving the practicality of the present invention in actual use.

[0054] As a preferred embodiment, based on the above method, further, the length of the main air tube 16 is greater than the length of the sleeve 17. With this structural setting, the sleeve 17 has more space when moving axially, which effectively avoids mechanical interference at the connection between the sleeve 17 and the main air tube 16, resulting in a contact dead angle between the application air bag 18 and the inner wall of the vagina, thereby further improving the application effect.

[0055] As a preferred embodiment, based on the above method, further, the sleeve 17 and the main air pipe 16 are detachably connected. The support tube body 1 is also provided with a scale mark, and the scale mark is used to indicate the length of the support tube body 1 extending into the human vagina. With this structural setting, the practicality of the present invention in actual use can be further improved.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
