Description

Technical Field

[0001] The invention belongs to the technical field of gynecological instruments, and in particular relates to a gynecological medicine pusher. Background Art

[0002] Gynecological vaginal medicine pushers play an important role in the treatment of gynecological diseases. They are mainly used to accurately push drugs into the vagina, so that the drugs can directly act on the lesion site and improve the treatment effect.

[0003] At present, vaginal medicine pushers are usually composed of a push rod, a medicine cartridge, a piston, a medicine delivery head, etc., and their design fully considers the physiological characteristics of women, is easy to operate, can effectively control the drug dosage, and accurately delivers the drug to the deep vagina to promote drug absorption, thus providing a convenient and effective drug delivery method for the treatment of gynecological diseases, which helps patients recover health faster. For example, a gynecological medicine pusher disclosed in patent announcement number CN112691283B;

[0004] The female vagina is relatively fragile. In order to avoid damage to the inner wall of the vagina when the cartridge is inserted into the vagina, the head end of the cartridge is usually specially designed, such as being set into an arc shape or using a flexible material. However, when the cartridge is inserted, due to the fit with the inner wall of the vagina, the secretions in the vagina will be pushed to the lesion site deep in the vagina along with the cartridge. In addition, since the external opening of the vagina is easily in contact with the external environment (such as contact with underwear), it may contain more bacteria. These bacteria are also easily pushed into the deep vagina along with the secretions, thereby increasing the risk of infection at the lesion site deep in the vagina, which is not conducive to vaginal treatment.

[0034] The hand-held lower seat 9 is integrally formed and sleeved on the outside of the mounting sleeve 2. The hand-held lower seat 9 is cam-shaped. The hand-held lower seat 9 is installed with a first air supply unit 10, and the first air supply unit 10 is used to supply air to the inside of the first expansion assembly 6. The first air supply unit 10 includes a first arc-shaped cavity 101 and a first air cavity 102 opened inside the hand-held lower seat 9. The first arc-shaped cavity 101 and the first air cavity 102 are jointly provided with a first connecting hole 103. The cavity wall of the first arc-shaped cavity 101 away from the first connecting hole 103 is provided with an exhaust hole 104. The bottom of the first annular groove 61 is provided with a first air hole 104. An air supply channel 105 connected to the exhaust hole 104 is provided together with the inner wall of the cartridge 1, a first air push piston 106 is slidably provided inside the first air cavity 102, and a first spring 107 is fixedly provided between the first air push piston 106 and the first air cavity 102, a first air push rod 108 is fixedly installed on the side wall of the first air push piston 106, and the rod wall of the first air push rod 108 is slidably connected to the cavity wall of the first air cavity 102, and the air inside the first arc-shaped cavity 101 can enter the first annular groove 61 through the exhaust hole 104 and the air supply channel 105.

[0035] The handheld upper seat 11 is slidably sleeved on the outside of the mounting sleeve 2, and the handheld upper seat 11 is cam-shaped. A second air supply unit 12 is installed inside the handheld lower seat 9, and the second air supply unit 12 is used to supply air to the inside of the second expansion assembly 8. The second air supply unit 12 includes a second arc-shaped cavity 121 and a second air cavity 122 opened inside the handheld upper seat 11. The second arc-shaped cavity 121 and the second air cavity 122 are jointly provided with a second connecting hole 123. The cavity wall of the second arc-shaped cavity 121 away from the second connecting hole 123 is fixedly plugged with an exhaust short pipe 124, and the groove wall of the second annular groove 81 is fixedly connected to the second annular groove 81. An exhaust long tube 125 is inserted, and the exhaust short tube 124 is connected to the exhaust long tube 125, a second air push piston 126 is slidably provided inside the second air cavity 122, and a second spring 127 is fixedly provided between the second air push piston 126 and the second air cavity 122, a second air push rod 128 is fixedly installed on the side wall of the second air push piston 126, and the rod wall of the second air push rod 128 is slidably connected to the cavity wall of the second air cavity 122, the exhaust short tube 124 is slidably connected to the end face of the hand-held lower seat 9, and a nut is used to connect and fix the exhaust short tube 124 and the exhaust long tube 125.

[0036] Two sliders 13 are fixedly mounted on the inner wall of the handheld upper seat 11, and two slide grooves 14 matching the sliders 13 are provided on the outer wall of the mounting sleeve 2. A distance retaining ring 15 is threadedly connected to the outer wall of the mounting sleeve 2, and the distance of a single movement of the cartridge 1 can be adjusted by the distance retaining ring 15.

[0037] The end of the cartridge 1 away from the mounting sleeve 2 is in an arc shape, and the outer wall of the cartridge 1 is threadedly connected with a sealing cover 16, and the inner wall of the sealing cover 16 abuts against the end of the cartridge 1. The sealing cover 16 can be used to seal and protect the medicine outlet 3 of the cartridge 1 to prevent bacteria from being contaminated. Secondly, the outer walls of the fixing ring 5 and the sliding ring 7 are threadedly fitted with sealing rings (not shown in the figure), which can prevent the fixing ring 5 and the sliding ring 7 from being contaminated with bacteria when not in use.

[0038] The outer side walls of the first annular elastic membrane 62 and the second annular elastic membrane 82 are integrally formed with a plurality of massage convex particles 17 . The massage convex particles 17 can assist in massaging the inner wall of the vagina when the first annular elastic membrane 62 and the second annular elastic membrane 82 swell.

[0039] The operating principle of the present invention is now described as follows: the user (the user is the patient himself) washes his hands first to ensure that the operation is clean, then unscrews the sealing cover 16 from the cartridge 1, and unscrews the sealing rings on the outer walls of the fixing ring 5 and the sliding ring 7 (the sealing ring is not shown in the figure, which can prevent the fixing ring 5 and the sliding ring 7 from being contaminated with bacteria before use), and inserts the cartridge 1 into the gel medicine storage container (the insertion end of the cartridge 1 is one end of the medicine outlet 3), and then pulls the piston push rod 42, the piston push rod 42 can drive the medicine pushing piston 41 to move toward the side of the mounting sleeve 2, so that the gel medicine can be sucked into the cartridge 1 through the medicine outlet 3. After sucking an appropriate amount of gel medicine, the user takes a suitable body position, for example, taking a supine position with the legs bent and spread apart, or choosing a squatting position, to ensure that the vagina is fully exposed so that the medicine can be smoothly pushed into the vagina;

[0040] Subsequently, one hand holds the hand-held lower seat 9, and the other hand holds the hand-held upper seat 11, and the two middle fingers are placed on the handles of the first gas push rod 108 and the second gas push rod 128 respectively, and then the cartridge 1 is inserted into the vagina, so that the fixing ring 5 also enters the vagina (the hand-held upper seat 11 does not move at this time), and then, the first gas push rod 108 at the hand-held lower seat 9 is pressed. At this time, the first gas push rod 108 will drive the first gas push piston 106 to move toward the first connecting hole 103, so as to squeeze the space inside the first air cavity 102. At this time, the air inside the first air cavity 102 will enter the first arc-shaped cavity 101 through the first connecting hole 103 and pass through the exhaust hole 104. and the air supply channel 105 enter the first annular groove 61, so that the first annular elastic membrane 62 expands and bulges. At this time, the position of the vaginal inner wall located at the first annular elastic membrane 62 is expanded to support a certain space (due to the different inner diameters of different vaginas, in order to avoid excessive expansion of the vagina and damage to the vaginal inner wall, a pressure gauge is provided on the side wall of the first arc cavity 101 and the second arc cavity 121. The pressure gauge is not shown in the figure. By checking the value of the pressure gauge, the air pressure inside the first annular groove 61 and the second annular groove 81 can be known. After the air pressure reaches the set value, the first air push rod 108 and the second air push rod 128 should be stopped);

[0041] Subsequently, the hand-held upper seat 11 is pulled with the other hand to move, so that the hand-held upper seat 11 moves toward the medicine pushing piston 41. At this time, under the action of the exhaust short pipe 124 and the exhaust long pipe 125, the sliding ring 7 will move synchronously toward the fixed ring 5, and when the hand-held upper seat 11 moves, it will drive the slider 13 to move synchronously. When the slider 13 moves to the end position of the slide groove 14, the slider 13 will be blocked, and the hand-held upper seat 11 cannot continue to move (refer to Figure 2 , Figure 2 As shown in the figure, when the slider 13 moves to the end of the slide groove 14, the position relationship between the hand-held upper seat 11 and the hand-held lower seat 9 is achieved, and the sliding ring 7 moves to a position in contact with the fixing ring 5 (i.e., the sliding ring 7 also enters the vagina). Subsequently, the second air push rod 128 of the hand-held upper seat 11 is pressed, and the second air push rod 128 can drive the second air push piston 126 to move, thereby squeezing the space inside the second air cavity 122, and then the air inside the second air cavity 122 can be pushed out through the second connecting hole 123 and the second arc cavity 121. , the exhaust short pipe 124 and the exhaust long pipe 125 are sent into the second annular groove 81, so that the second annular elastic membrane 82 expands and bulges, and then the first air push rod 108 at the hand-held lower seat 9 is released. At this time, under the action of the first spring 107, the first air push piston 106 moves back and resets, and under the elastic recovery action of the first annular elastic membrane 62, the excess air in the first annular groove 61 will flow back into the first air cavity 102. At this time, the first annular elastic membrane 62 rebounds and recovers. At this time, the vagina is supported by the second annular elastic membrane 82;

[0042] Then, the cartridge 1 is pushed to move (the hand-held upper seat 11 is kept stationary at this time). Since the opening of the vagina supported by the second annular elastic membrane 82 is larger than the outer diameters of the fixing ring 5 and the sliding ring 7, when the cartridge 1 drives the fixing ring 5 to move, the inner wall of the vagina is propped up, and the end of the cartridge 1 and the fixing ring 5 will not contact the inner wall of the vagina. Therefore, the cartridge 1 and the fixing ring 5 will not push the vaginal secretions to move deep into the vagina. When the cartridge 1 moves, the cartridge 1 will drive the slide groove 14 to move relative to the slider 13. When the slider 13 moves from one end of the slide groove 14 to the other end, the slide groove 14 will move to the inner wall of the vagina. After that, the slider 13 is blocked by the slide groove 14 again. At this time, it means that the cartridge 1 has moved a specific distance (the distance is the length of the slide groove 14, and the length of the slide groove 14 is generally set to 1 cm). Then, the first gas push rod 108 at the hand-held lower seat 9 is pressed again to make the first annular elastic membrane 62 bulge again, and then the second gas push rod 128 at the hand-held upper seat 11 is released, and the hand-held upper seat 11 is pushed to move, so that the sliding ring 7 moves back to the position of the fixed ring 5, and the second gas push rod 128 is pressed again to make the second annular elastic membrane 82 expand again. The first air push rod 108 is then released, and the cartridge 1 is moved again, and the cycle is alternating, so that the cartridge 1 moves toward the inside of the vagina. Since the cartridge 1 does not contact the inner wall of the vagina when it moves, the cartridge 1 will not push the secretions deep into the vagina when it moves, thereby reducing the risk of secondary infection at the lesion site deep in the vagina (i.e., bacteria are not easy to contact the lesion site deep in the vagina with the flow of secretions). Secondly, since one end of the drug outlet 3 of the cartridge 1 is at a certain distance (1 cm) from the fixing ring 5, when the cartridge 1 moves to the required position (i.e., the lesion site of the vagina), the drug outlet 3 of the cartridge 1 is moved to the inner wall of the vagina. In order to spray the gel medicine directly on the vaginal lesion, the medicine outlet 3 needs to be kept at a certain distance from the lesion (since the gel medicine is sprayed at a certain speed, the distance needs to be kept, and the distance is generally in the range of 0.5 cm to 1 cm). Therefore, the fixing ring 5 is actually at a certain distance from the lesion. The bacteria that may be contaminated when the fixing ring 5 contacts the vaginal opening will not directly contact the lesion, thereby reducing the probability of the lesion deep in the vagina being infected by bacteria as much as possible, and reducing the possibility of secondary infection of the lesion deep in the vagina;

[0043] Since, when the cartridge 1 is moved once, after the slider 13 moves from one end of the slide groove 14 to the other end, the slider 13 cannot move further, so the single movement distance of the cartridge 1 is determined, and the user only needs to remember the number of movements of the cartridge 1 to know the insertion depth of the cartridge 1. Taking the length of the slide groove 14 as 1 cm as an example, the single movement distance of the cartridge 1 is 1 cm. When the number of movements reaches 5 times, the insertion depth of the cartridge 1 reaches 5 cm. The user can control the insertion depth of the cartridge 1 according to the insertion depth required by the medical staff. Secondly, by twisting the distance-fixing retaining ring 15, the limit position of the handheld upper seat 11 can be adjusted. For example, when the single movement distance of the cartridge 1 is required to be 0.5 cm, at this time, the distance-fixing retaining ring 15 can be twisted to the middle position of the slide groove 14, so that the user can flexibly adjust according to the use requirements;

[0044] After the cartridge 1 reaches the required position, the hand holding the handheld upper seat 11 is released, and then the piston push rod 42 is pushed to move, so that the medicine pushing piston 41 moves toward the medicine outlet hole 3, so that the gel medicine inside the cartridge 1 can be discharged through the medicine outlet hole 3, and then the medicine can be delivered to the designated position inside the vagina;

[0045] After the drug delivery is completed, since the gel drug has just been discharged and has not yet fully contacted the vagina, if the cartridge 1 is directly pulled out, part of the gel drug will be easily taken out, thereby causing drug loss. Therefore, the cartridge 1 is temporarily left inside the vagina. Subsequently, the first air push rod 108 and the second air push rod 128 are alternately pressed to make the first annular elastic membrane 62 and the second annular elastic membrane 82 expand and bulge alternately. The first annular elastic membrane 62 and the second annular elastic membrane 82 can alternately squeeze the inner wall of the vagina. In conjunction with the massage convex particles 17, squeezing the inner wall of the vagina will produce a certain pressure stimulation on the blood vessels around the vagina, thereby accelerating local blood circulation. The accelerated blood flow brings more oxygen and nutrients, and also enhances the metabolic activity of the vaginal mucosal cells. In this case, the cell's ability to absorb and transport drugs will also be correspondingly improved, thereby promoting the vagina's absorption of the gel drug. After the gel drug is delivered for a certain period of time (generally about 1 minute, to prevent the cartridge 1 from being in the vagina for too long, causing discomfort to the user), the cartridge 1 is slowly pulled out of the vagina.

[0046] After each use, the installation sleeve 2 needs to be separated from the cartridge 1, and the entire device needs to be cleaned and disinfected using a special cleaning agent. The cartridge 1 can also be partially replaced to ensure safety for the next use.

[0047] 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, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
