Description

Technical Field

[0001] This invention relates to a medication application device, specifically a gynecological medication application device, belonging to the field of medical device technology. Background Technology

[0002] Medical gynecological medication inserters are specially designed auxiliary medical devices, mainly used to accurately and safely deliver medications (such as suppositories, ointments, gels, etc.) deep into the vagina or cervix of women to achieve the purpose of local treatment. Common types include disposable pushers, medication sticks, and medical vaginal irrigators. However, the vagina has many folds, and traditional medication inserters are mostly thin rod-shaped structures, which means that specific body positions, such as the knee-bent supine position or the lithotomy position, are required to ensure smooth insertion of the medication inserter.

[0003] A Chinese patent entitled "A Gynecological Uterine Wall Medication Application Device" (patent number ZL CN202110654162.7) discloses a uterine wall medication application technology. It includes an injection mechanism that works in conjunction with a squeezing mechanism. The squeezing mechanism controls the injection mechanism, allowing it to spray medication, thus effectively reducing manpower consumption during the application process. An infusion mechanism works in conjunction with the injection mechanism, delivering medication to the injection mechanism, further enhancing the convenience of application. However, while convenient, the device's overall structure is overly complex, and gynecological medication application devices are generally not reusable and cross-use is prohibited, resulting in high operating costs. Furthermore, the device only has a nozzle-related structure and cannot be used with suppositories, capsules, ointments, or other medications.

[0004] Chinese patent titled "Medical Gynecological Medication Applicator" (patent number ZL202210230563.4) discloses a medication applicator technology. It is characterized by its simple operation, ability to help patients deliver medication more effectively to the genital area, and reusability. It also features a side-support stabilizing mechanism to help stabilize the patient's legs, thus facilitating medication application. However, this applicator also suffers from problems such as complex structure, high cost, and inapplicability to various medications. Furthermore, it lacks a bending / deformation function, requiring a specific body position for successful insertion, making it inconvenient to use. Therefore, this paper proposes a medical gynecological medication application device. Summary of the Invention

[0050] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0051] Example 1

[0052] like Figures 1-8 As shown, this embodiment of the invention provides a medical gynecological medication application device, including a medication application tube 1 and a connecting mechanism 2. The medication application tube 1 includes an end support tube 101, a connecting support tube 102, and a push-pull head 103.

[0053] The connecting support tube 102 is located on one side of the end support tube 101. The connecting mechanism 2 is connected between the end support tube 101 and the connecting support tube 102 and has a bending function to reduce the requirements for the position of the medicine feeding body. The push-pull head 103 is slidably connected to the inner wall of the end support tube 101. The inner wall of the connecting support tube 102 is equipped with a medicine pushing mechanism 4 having a connecting end 403 and a screw hole 404. The screw hole 404 is opened at one end of the connecting end 403. A split medicine control mechanism 3 is detachably installed at one end of the connecting support tube 102.

[0054] Among them, the drug pushing mechanism 4 is used to drive the split drug control mechanism 3 to perform the drug delivery action;

[0055] Among them, the split-type drug control mechanism 3 adopts a quick-release structure, and the drug delivery device is suitable for suppository or capsule delivery needs by using a replacement method.

[0056] In one embodiment, the connecting mechanism 2 includes a flexible connecting tube 201, an inner support frame 202, and a universal joint chain 203;

[0057] The flexible connecting tube 201 and the inner support frame 202 are both fixedly connected between the end support tube 101 and the connecting support tube 102. The flexible connecting tube 201 covers the outside of the inner support frame 202. One end of the universal joint chain 203 is fixedly connected to one end of the push-pull head 103, and the other end of the universal joint chain 203 is fixedly connected to one end of the connecting end head 403.

[0058] The flexible connecting tube 201 and the inner support frame 202 allow the middle part of the drug delivery device to bend and deform. The inner support frame 202 is used to improve the overall strength of the flexible connecting tube 201 and avoid excessive deformation during the use of the drug delivery device.

[0059] In one embodiment, the drug pushing mechanism 4 further includes an inner support plate 401 and a spring 402;

[0060] The inner support plate 401 is located inside the connecting support tube 102 and is an integrally formed structure. One end of the spring 402 is fixedly connected to one end of the inner support plate 401, and the other end of the spring 402 is fixedly connected to one side of the connecting end 403.

[0061] The inner support plate 401 is used to limit one end of the spring 402. The spring 402 is compressed by the moving connecting end 403 so that the spring 402 can be compressed and stored to provide power for subsequent drug application.

[0062] In one embodiment, the split-type drug control mechanism 3 applicable to suppositories or capsules consists of a conical sleeve 301, a first locking part 302, a first limiting plate 303, a first connecting rod 304, and a drug-binding component 305.

[0063] The first snap-fit ​​part 302 is located between the conical sleeve 301 and the connecting support tube 102, and the conical sleeve 301 and the connecting support tube 102 are connected by snap-fit. The first limiting plate 303 is located inside the conical sleeve 301 and is integrally formed with the conical sleeve 301. The outer side wall of the first connecting rod 304 is slidably connected to the inner side wall of the first limiting plate 303. One end of the first connecting rod 304 is threadedly connected to the inner side wall of the screw hole 404. The drug bundle 305 is fixedly connected to one side of the inner side wall of the conical sleeve 301, and the other end of the first connecting rod 304 is fixedly connected to one side of the drug bundle 305.

[0064] The drug-binding component 305 consists of a high-elasticity diaphragm 351 and an elastic constraint ring 352;

[0065] The high-elastic diaphragm 351 is fixedly connected to one side of the inner wall of the conical sleeve 301. One end of the first connecting rod 304 is fixedly connected to the middle of one side of the high-elastic diaphragm 351. There are several elastic constraint rings 352, all of which are fitted into the inner wall of the high-elastic diaphragm 351. The elastic modulus of the elastic constraint rings 352 is greater than that of the high-elastic diaphragm 351, and they are used to constrain the high-elastic diaphragm 351 locally after it is deformed.

[0066] The first connecting rod 304 is moved to stretch and deform the high-elastic diaphragm 351, forming a cavity inside the high-elastic diaphragm 351. Then, the suppository or capsule is taken out and pushed into the cavity of the high-elastic diaphragm 351 by pressing, so that the elastic restraint ring 352 deforms and works with the high-elastic diaphragm 351 to wrap and fix the suppository or capsule.

[0067] In one embodiment, an easy-tear sticker 51 is attached to one end of the tapered sleeve 301, and a first card 52 is engaged on one side of the outer wall of the first connecting rod 304.

[0068] The easy-tear sticker 51 is used to protect the end of the conical sleeve 301 from bacteria, and the first card 52 is used to limit the first connecting rod 304.

[0069] When the present invention is in operation: First, the type of drug required is determined according to actual needs. When suppositories or capsules are needed for drug administration, the first connecting rod 304 is moved by moving the conical sleeve 301. The moving first connecting rod 304 is inserted into the screw hole 404 and connected by threads in the direction of rotation. During installation, the resistance of the first connecting rod 304 can be increased by pressing one side of the easy-tear sticker 51 to ensure that the first connecting rod 304 is connected to the screw hole 404 in place. Then, the assembly operation of the split drug control mechanism 3 is completed by moving the conical sleeve 301 and engaging it with one end of the connecting support tube 102 using the first snap-fit ​​part 302.

[0070] When it is necessary to secure the suppository or capsule, the easy-tear adhesive tape 51 is removed from the conical sleeve 301. Then, the universal joint chain 203 is moved by the moving push-pull head 103. The moving universal joint chain 203 moves the connecting end 403, which in turn moves the spring 402 and the first connecting rod 304. The moving spring 402 is compressed and stores force, while the moving first connecting rod 304 stretches and deforms the high-elastic diaphragm 351, creating a cavity within it. The suppository or capsule is then removed and pushed into the cavity of the high-elastic diaphragm 351 by pressing, causing the elastic restraint ring 352 to deform. This, in conjunction with the high-elastic diaphragm 351, secures the suppository or capsule, achieving a wrapping effect as described above. Figure 9 As shown, it should be noted that if the suppository or capsule is teardrop-shaped, the larger end must be located at the deepest part of the cavity.

[0071] When medication needs to be applied, the moving end support tube 101, in conjunction with the flexible connecting tube 201, drives the connecting support tube 102 and the conical sleeve 301 to move, so that the conical sleeve 301, the connecting support tube 102, and the flexible connecting tube 201 can be inserted into the vagina. To ensure smooth insertion, medical water-based lubricant can be applied to the outside of the conical sleeve 301, the connecting support tube 102, and the flexible connecting tube 201 to reduce discomfort during medication application. During insertion, the flexible connecting tube 201, in conjunction with the inner support frame 202 and the universal joint chain 203, allows the middle part of the medication applicator to bend and deform adaptively, reducing the need for different body positions during medication application.

[0072] When the end of the conical sleeve 301 is inserted into the designated position, by releasing the push-pull head 103, the stored spring 402 pushes the connecting end 403 to move in the opposite direction. The moving connecting end 403 drives the first connecting rod 304 and the high-elastic diaphragm 351 to reset, so that the reset first connecting rod 304 can push out the suppository or capsule wrapped in the high-elastic diaphragm 351, thus completing the medication application.

[0073] The internal support frame 202 is used to improve the overall strength of the flexible connecting pipe 201 and avoid excessive deformation during the use of the medicine applicator.

[0074] Example 2

[0075] like Figures 1-13 As shown, this embodiment of the invention provides a medical gynecological medication application device, including a medication application tube 1 and a connecting mechanism 2. The medication application tube 1 includes an end support tube 101, a connecting support tube 102, and a push-pull head 103.

[0076] The connecting support tube 102 is located on one side of the end support tube 101. The connecting mechanism 2 is connected between the end support tube 101 and the connecting support tube 102 and has a bending function to reduce the requirements for the position of the medicine feeding body. The push-pull head 103 is slidably connected to the inner wall of the end support tube 101. The inner wall of the connecting support tube 102 is equipped with a medicine pushing mechanism 4 having a connecting end 403 and a screw hole 404. The screw hole 404 is opened at one end of the connecting end 403. A split medicine control mechanism 3 is detachably installed at one end of the connecting support tube 102.

[0077] Among them, the drug pushing mechanism 4 is used to drive the split drug control mechanism 3 to perform the drug delivery action;

[0078] Among them, the split-type drug control mechanism 3 adopts a quick-release structure, and the drug application device is suitable for the application needs of ointments or gels by means of replacement.

[0079] In one embodiment, the split-type drug control mechanism 3 for ointments or gels consists of a first bundle of drug cartridges 310, a first cylindrical sleeve 311, a second locking part 312, a second limiting plate 313, a second connecting rod 314, a first hammer head 315, a conical plug 316, and a plurality of drug discharge holes 317.

[0080] The first cartridge 310 is threaded to one end of the first cylindrical sleeve 311. The second snap-fit ​​part 312 is located between the first cylindrical sleeve 311 and the connecting support tube 102, and the first cylindrical sleeve 311 and the connecting support tube 102 are connected by snap-fit. The second limiting plate 313 is located inside the first cylindrical sleeve 311 and is integrally formed with the first cylindrical sleeve 311. The outer side wall of the second connecting rod 314 is slidably connected to the inner side wall of the second limiting plate 313. One end of the second connecting rod 314 is threaded to the inner side wall of the screw hole 404. The first hammer head 315 is located on the other side of the second connecting rod 314. The conical plug 316 covers the outer side wall of the first hammer head 315 and is slidably connected to the inner side wall of the first cartridge 310. Several discharge holes 317 are opened on the outer side wall of the first cartridge 310.

[0081] In one embodiment, a first tear-off ring 53 is attached to the outer wall of the first cartridge 310, and a second clip 54 is engaged on one side of the outer wall of the second connecting rod 314.

[0082] When ointment or gel is needed for application, the second connecting rod 314 is moved by moving the first cylindrical sleeve 311. The moving second connecting rod 314 is inserted into the screw hole 404 and connected in place. Then, by moving the first cylindrical sleeve 311 and engaging it with the second snap-fit ​​part 312 at one end of the connecting support tube 102, the assembly operation of the split-type drug control mechanism 3 can be completed.

[0083] When it is necessary to fix the drug, the universal joint chain 203 is driven to move by the moving push-pull head 103. The moving universal joint chain 203 drives the connecting end 403 to move. The moving connecting end 403 drives the spring 402 and the second connecting rod 314 to move. The moving spring 402 is compressed and stores force. The moving second connecting rod 314 drives the first hammer head 315 and the cone plug 316 to slide into the first cylindrical sleeve 311. Then, the first bundle of medicine 310 is removed from the first cylindrical sleeve 311 by rotating it so that the ointment or gel drug can be placed into the first bundle of medicine 310. Then, the first bundle of medicine 310 containing the drug is connected and fixed to the first cylindrical sleeve 311 by the thread, thus completing the fixation of the ointment or gel.

[0084] When medication needs to be applied, the first tear-off ring 53 is torn off the first bundle of medicine 310, exposing the discharge hole 317. After the medication device is inserted into the designated position in the vagina, the connecting end 403 drives the second connecting rod 314 to move in the opposite direction. At the same time, the second connecting rod 314, in conjunction with the first hammer head 315, drives the cone plug 316 to move. The moving cone plug 316 squeezes the medicine in the first bundle of medicine 310, causing it to be squeezed out from the discharge hole 317 under pressure, thus completing the medication application.

The medication application tube 1 includes an end support tube 101, a connecting support tube 102, and a push-pull head 103.

[0087] The connecting support tube 102 is located on one side of the end support tube 101. The connecting mechanism 2 is connected between the end support tube 101 and the connecting support tube 102 and has a bending function to reduce the requirements for the position of the medicine feeding body. The push-pull head 103 is slidably connected to the inner wall of the end support tube 101. The inner wall of the connecting support tube 102 is equipped with a medicine pushing mechanism 4 having a connecting end 403 and a screw hole 404. The screw hole 404 is opened at one end of the connecting end 403. A split medicine control mechanism 3 is detachably installed at one end of the connecting support tube 102.

[0088] Among them, the drug pushing mechanism 4 is used to drive the split drug control mechanism 3 to perform the drug delivery action;

[0089] Among them, the split-type drug control mechanism 3 adopts a quick-release structure, and by replacing it, the drug delivery device can meet the drug delivery needs of the liquid.

The third snap-fit ​​part 322 is located between the second cylindrical sleeve 321 and the connecting support tube 102, connecting the second cylindrical sleeve 321 and the connecting support tube 102 by means of a snap-fit. The third limiting plate 323 is located inside the second cylindrical sleeve 321 and is integrally formed with the second cylindrical sleeve 321. The outer wall of the third connecting rod 324 is slidably connected to the third limiting plate. The inner wall of 323, one end of the third connecting rod 324 is threaded to the inner wall of the screw hole 404, the second hammer head 325 is located on the other side of the third connecting rod 324, the concave plug 326 covers the outer wall of the second hammer head 325 and is slidably connected to the inner wall of the second bundle of medicine 320, a number of drainage holes 327 are all opened on the outer wall of the second bundle of medicine 320, and a number of rubber inner hole plugs 328 are respectively fixedly connected to the inner wall of the number of drainage holes 327.

[0092] In one embodiment, a second tear-off ring 55 is attached to the outer wall of the second cartridge 320, and a third card 56 is engaged on one side of the outer wall of the third connecting rod 324.

[0093] When it is necessary to apply the medicine with the liquid, the third connecting rod 324 is moved by moving the second cylindrical sleeve 321. The moving third connecting rod 324 is inserted into the screw hole 404 and connected in place. Then, by moving the second cylindrical sleeve 321 and using the third snap-fit ​​part 322 to engage with one end of the connecting support tube 102, the assembly operation of the split medicine control mechanism 3 can be completed.

[0094] When it is necessary to fix the liquid medicine, the universal joint chain 203 is driven to move by the moving push-pull head 103. The moving universal joint chain 203 drives the connecting end 403 to move, and the moving connecting end 403 drives the spring 402 and the third connecting rod 324 to move. The moving spring 402 is compressed and stores force, and the moving third connecting rod 324 drives the second hammer head 325 and the concave plug 326 to slide into the second cylindrical sleeve 321. Then, the second bundle of medicine 320 is removed from the second cylindrical sleeve 321 by rotating it so that the liquid medicine can be poured into the second bundle of medicine 320. Then, the second bundle of medicine 320 containing the medicine is connected and fixed to the second cylindrical sleeve 321 by the thread, thus completing the fixation of the liquid medicine. It should be noted that during the connection process, the second bundle of medicine 320 should be prevented from tilting.

[0095] When medication application is required, the second tear-off ring 55 is torn off the second bundle of medication 320, exposing the drainage hole 327. After the medication application device is inserted into the designated position in the vagina, the connecting end 403 drives the third connecting rod 324 in the opposite direction. Simultaneously, the third connecting rod 324, in conjunction with the second hammer head 325, drives the concave plug 326. The moving concave plug 326 squeezes the medication inside the second bundle of medication 320, and the pressure opens the hole in the rubber inner plug 328, allowing the medication to be squeezed out through the drainage hole 327 for medication application. The rubber inner plug 328 is used to seal the drainage hole 327 before medication application to prevent medication leakage.
