Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and specifically relates to a perineum medicator for obstetrics and gynecology. Background Art

[0002] In the clinical treatment of obstetrics and gynecology, perineum medication is an important treatment method for various perineum diseases, such as vaginitis, vulvitis, etc. Precise, safe and convenient medication is crucial for improving the treatment effect. However, there are many deficiencies in the existing perineum medication devices and methods for obstetrics and gynecology.

[0003] Traditional medication methods have great limitations in controlling the spraying position, depth and angle. Many devices cannot be flexibly adjusted according to the specific conditions and physical conditions of patients, resulting in the inability of drugs to be accurately sprayed on the perineum area that needs treatment. For example, for some cases where the lesion location is deeper or the range is special, the existing medicators are difficult to accurately deliver the drugs, making some drugs unable to play their roles, reducing the utilization rate of drugs, and thus affecting the treatment effect.

[0015] The present invention provides a perineum medicator for obstetrics and gynecology. It has the following beneficial effects: (1). For the perineum medicator for obstetrics and gynecology, by setting the medicine spraying component, the extension component and the positioning component of the medicine spraying component work together, so that the position, depth and angle of medicine spraying can be adjusted. Medical staff can push the push plate to adjust the medicine spraying position and depth according to the specific conditions and disease needs of the patient, and pull the pull plate to change the shape of the soft shell to adjust the medicine spraying angle. For example, when it is necessary to expand the medicine spraying range, push the pull plate to make the soft shell in a sharp cone shape; when it is necessary to reduce the medicine spraying area, pull the pull plate to make the soft shell in a flat shape. This flexible adjustment method ensures that the medicine can be accurately sprayed on the perineum, improving the utilization rate of the medicine and the treatment effect.

[0016] (2) For this perineum drug applicator for obstetrics and gynecology, by setting a pumping component, the jet component of the pumping component utilizes the compressibility of gas and the principle of pressure balance. Medical staff can press and release the sliding plate to compress, eject the gas in the airbag, and inhale external air, providing power for the delivery of the liquid medicine in the medicine bottle. In the medicine spraying component, pushing the push plate can adjust the spraying position and depth, and pulling the pull plate can change the shape of the soft shell to adjust the spraying angle. These operations are very intuitive and easy to control. Medical staff can flexibly adjust according to actual needs to ensure the smooth progress of the drug delivery process.

[0017] (3) For this perineum drug applicator for obstetrics and gynecology, by setting a transmission component, the expansion component and the limit component in the transmission component cooperate ingeniously. Medical staff only need to hold the handle and press the pressing handle. According to the lever and ratchet principle, they can easily convert the rotational motion of the pressing handle into the linear motion of the pull rope, and then realize the expansion function of the expansion component. This operation method is simple and direct, without complex skills and additional tools, greatly reducing the operation difficulty of medical staff. Moreover, the positioning block effectively limits the rotation range of the pressing handle, avoiding the risk of excessive expansion, making the expansion process safer and more controllable, and improving the convenience and efficiency of the operation.

[0018] (4) For this perineum drug applicator for obstetrics and gynecology, by setting a clamping component, the design of the clamping component enables it to adapt to medicine bottles of different sizes and shapes. Just place the medicine bottle between the two rotating plates, and the pulling force of the tension spring can make the rotating plates tightly clamp the medicine bottle, improving the versatility of the device. At the same time, the existence of the soft ring avoids damage to the medicine bottle, extending the service life of the medicine bottle and the device. Brief Description of the Drawings

When a medical staff member pushes the push plate 56, according to the principle of force transmission, the push plate 56 stably transmits the force to the extension column 51 through the connecting plate 55, so that the extension column 51 slides smoothly on the inner wall of the expansion assembly 2. This process can realize the adjustment of the medicine spraying position and depth.

[0023] The expansion assembly 2 includes a main housing 22, a secondary housing 21 is rotatably connected to the inner wall of the main housing 22 through a fixed shaft 23, and the outer wall of the fixed shaft 23 is fixedly connected to the inner wall of the main housing 22. Connecting ropes 26 are fixedly connected to the outer walls on both sides of the secondary housing 21, torsion springs 24 are fixedly connected to the outer walls on both sides of the secondary housing 21, an extension housing 25 is fixedly connected to the outer wall of the main housing 22, a pull rope 27 is slidably connected to the inner wall of the extension housing 25 through a limiting housing 28, and the outer wall of the limiting housing 28 is fixedly connected to the inner wall of the extension housing 25. The inner wall of the limiting housing 28 is slidably connected to the outer wall of the pull rope 27. One end of the torsion spring 24 away from the secondary housing 21 is fixedly connected to the outer wall of the fixed shaft 23, and one end of the connecting rope 26 away from the secondary housing 21 is fixedly connected to the outer wall of the pull rope 27. Under the guiding action of the limiting housing 28, the pull rope 27 slides smoothly along the inside of the extension housing 25, and the secondary housing 21 is pulled to rotate around the fixed shaft 23 through the connecting rope 26. During this process, the secondary housing 21 needs to overcome the torsion force of the torsion spring 24, so as to realize the expansion function of the expansion assembly 2.

[0024] The limiting component 9 includes a grip 91. The inner wall of the grip 91 is rotationally connected with a pressing handle 92 through a cylinder. The outer wall of the grip 91 is fixedly connected with an arc-shaped toothed plate 94. The outer wall of the pressing handle 92 is fixedly connected with a fixing plate 95. The outer wall of the grip 91 is fixedly connected with a positioning block 93. The outer wall of the positioning block 93 is in contact with the outer wall of the pressing handle 92. The outer wall of the pressing handle 92 is meshed with the inner wall of the arc-shaped toothed plate 94. The top of the grip 91 is fixedly connected with the bottom of the extension housing 25. The inner wall of the fixing plate 95 is fixedly connected with one end of the pull rope 27 away from the connecting rope 26. When a medical staff holds the grip 91 and presses the pressing handle 92, according to the lever principle, with the cylinder as the fulcrum, the pressing handle 92 makes a circular motion around the fulcrum.

[0025] The air jetting component 7 includes a fixed pressing plate 71. The four corners of the fixed pressing plate 71 are slidably connected with sliding plates 74 through limit posts. The outer wall of the sliding plate 74 is fixedly connected with an airbag 72. The bottom of the airbag 72 is fixedly connected with a one-way valve 76. The two sides of the top of the airbag 72 are fixedly connected with air jetting cones 79 through air guiding hoses 77. And the top of the air guiding hose 77 is fixedly connected with the outer wall of the air jetting cone 79. The outer wall of the air jetting cone 79 is fixedly connected with a fixed seat 78. The inner wall of the fixed seat 78 is fixedly connected with a medicine inlet cone 710. The outer wall of the bottom of the fixed seat 78 is fixedly connected with the outer wall of the top of the extension housing 25. One side of the airbag 72 away from the sliding plate 74 is in contact with the outer wall of the fixed pressing plate 71. The four corners of the fixed pressing plate 71 are fixedly connected with top springs 75. One end of the top spring 75 away from the fixed pressing plate 71 is fixedly connected with the outer wall of the sliding plate 74. The sliding plate 74 stably slides along the limit posts towards the fixed pressing plate 71, thereby squeezing the airbag 72. According to the principle of compressibility of gas, the volume of the gas in the airbag 72 is compressed and the pressure increases accordingly. At this time, the one-way valve 76 plays a key role, only allowing the gas to flow in one direction and preventing the gas from flowing out to the outside from the one-way valve 76.

[0026] The clamping component 6 includes rotating plates 62. There are two groups of rotating plates 62. And the bottom of each group of rotating plates 62 is rotationally connected with a mounting plate 61. The top of the rotating plate 62 is fixedly connected with a fixed ring 63. The outer wall of the fixed ring 63 is fixedly connected with a soft ring 64. And the soft ring 64 is linearly arranged along the outer wall of the fixed ring 63. The two sides of the top of the rotating plate 62 are fixedly connected with tension springs 66 through limit discs 65. And the outer wall of the limit disc 65 is fixedly connected with the outer wall of the tension spring 66. The outer wall of the limit disc 65 is fixedly connected with the outer wall of the top of the rotating plate 62. The bottom of the mounting plate 61 is fixedly connected with the outer wall of the top of the extension housing 25. The outer wall of the top of the mounting plate 61 is fixedly connected with the bottom of the fixed seat 78. The elastic force of the tension spring 66 will always make the two groups of rotating plates 62 tend to approach each other. When it is necessary to clamp the medicine bottle, the medical staff steadily places the medicine bottle between the two groups of rotating plates 62, and the pulling force of the tension spring 66 will make the rotating plates 62 tightly clamp the medicine bottle.

[0027] The expansion assembly 2 in the transmission component 8 is composed of a main shell 22, a sub-shell 21, a fixed shaft 23, a connecting rope 26, a torsion spring 24, an extension shell 25, a limit shell 28 and a pull rope 27. The main shell 22 is rotatably connected to the sub-shell 21 through the fixed shaft 23. The connecting rope 26 and the torsion spring 24 are connected on both sides of the sub-shell 21. The outer wall of the main shell 22 is fixed on the extension shell 25. The pull rope 27 can slide under the constraint of the limit shell 28. The limit assembly 9 includes a handle 91, a pressure handle 92, an arc-shaped tooth plate 94, a positioning block 93 and a fixed plate 95. The pressure handle 92 in the handle 91 rotates around the cylinder and engages with the arc-shaped tooth plate 94.

[0028] When the medical staff holds the grip 91 and presses the pressure handle 92, according to the lever principle, with the cylinder as the fulcrum, the pressure handle 92 performs a circular motion around the fulcrum. Since the pressure handle 92 is meshed with the arc-shaped tooth plate 94, the ratchet principle is cleverly used here. The arc-shaped tooth plate 94 is like the ratchet in the ratchet mechanism, which can clamp the position of the pressure handle 92, and then convert the rotational motion of the pressure handle 92 into a linear motion of the pull rope 27. Under the guidance of the limit shell 28, the pull rope 27 slides smoothly along the inside of the extension shell 25, and pulls the sub-shell 21 to rotate around the fixed axis 23 through the connecting rope 26. In this process, the sub-shell 21 needs to overcome the torsion of the torsion spring 24, so as to realize the expansion function of the expansion component 2. This expansion function can expand the patient's perineum and clearly expose the area where medication needs to be administered, which provides convenience for subsequent medication operations. At the same time, the positioning block 93 plays an important limiting role. It controls the rotation range of the pressure handle 92 to prevent damage to components or improper expansion caused by excessive rotation.

[0029] When the medical staff releases the pressure handle 92, according to Hooke's law, the restoring force generated by the elastic deformation of the torsion spring 24 will drive the sub-shell 21 to rotate in the opposite direction around the fixed axis 23, so that it returns to its initial position. At the same time, the meshing state of the pressure handle 92 and the arc-shaped tooth plate 94 continues to limit the expansion component 2, ensuring that it always remains in the appropriate position during the drug administration process to avoid accidental contraction or expansion. When the expansion state needs to be released, it is only necessary to move the arc-shaped tooth plate 94 smoothly away from the pressure handle 92 so that the arc-shaped tooth plate 94 and the pressure handle 92 are out of meshing state, and the restriction on the pressure handle 92 can be successfully released.

[0030] The jet component 7 in the pumping component 3 consists of a fixed pressing plate 71, a sliding plate 74, an airbag 72, a one-way valve 76, a gas guiding hose 77, a jet cone 79, a fixed seat 78 and a medicine inlet cone 710. The fixed pressing plate 71 is slidably connected to the sliding plate 74 through a limit post. The airbag 72 is fixed on the sliding plate 74. The one-way valve 76 is installed at the bottom of the airbag 72. Both sides of the top are connected to the jet cone 79 through the gas guiding hose 77. The jet cone 79 is fixed on the fixed seat 78. The medicine inlet cone 710 is installed in the fixed seat 78. A top spring 75 is arranged between the fixed pressing plate 71 and the sliding plate 74.

[0031] When the medical staff presses the sliding plate 74, the sliding plate 74 slides stably along the limit post towards the fixed pressing plate 71, thereby squeezing the airbag 72. According to the principle of compressibility of gas, the volume of the gas in the airbag 72 is compressed and the pressure increases accordingly. At this time, the one-way valve 76 plays a key role, only allowing the gas to flow in one direction and preventing the gas from flowing out to the outside from the one-way valve 76. Therefore, the compressed gas in the airbag 72 can only be transported to the jet cone 79 through the gas guiding hose 77, and the gas is ejected from the jet cone 79 at a high speed into the medicine bottle. Using the pressure generated by this high-speed air flow, the liquid medicine in the medicine bottle can be smoothly transported to the extension component 5.

[0032] When the medical staff releases the sliding plate 74, the elastic force generated by the elastic deformation of the top spring 75 will make the sliding plate 74 reset smoothly. During the reset process of the sliding plate 74, the internal pressure of the airbag 72 decreases. Under the action of atmospheric pressure, the outside air enters the airbag 72 through the one-way valve 76, making full preparations for the next jet operation. This process follows the principle of pressure balance of gas and cleverly utilizes the difference between atmospheric pressure and the internal pressure of the airbag 72 to realize the inhalation and discharge of gas.

[0033] The medicine spraying component 1 includes an extension component 5 and a positioning component 4. The extension component 5 consists of an extension column 51, a medicine spraying tube 53, a medicine spraying hose 54, a connecting plate 55 and a push plate 56. The medicine spraying tube 53 is fixed on the inner wall of the extension column 51. One end of the medicine spraying tube 53 is connected to the medicine spraying hose 54. The outer wall of the extension column 51 is connected to the push plate 56 through the connecting plate 55. The positioning component 4 includes a pull rod 42, a soft shell 41, a connecting frame 43 and a pull plate 44. The soft shell 41 is fixed on the outer wall of the pull rod 42. One end is connected to the pull plate 44 through the connecting frame 43. The limit ring 52 on the inner wall of the extension column 51 is slidably connected to the outer wall of the pull rod 42.

[0034] When the medical staff pushes the push plate 56, according to the principle of force transmission, the push plate 56 stably transmits the force to the extension column 51 through the connecting plate 55, enabling the extension column 51 to slide smoothly on the inner wall of the expansion component 2. This process can realize the adjustment of the medicine spraying position and depth, ensuring that the medicine can reach the medicine spraying position.

[0035] When medical staff pull the pull plate 44, the pull plate 44 drives the pull rod 42 to slide flexibly within the limit ring 52 through the connecting frame 43. Since the soft shell 41 is fixed to the outer wall of the pull rod 42, the sliding of the pull rod 42 will inevitably cause the soft shell 41 to deform. This deformation plays an important role. It can assist in adjusting the spraying angle of the medicine, enabling the medicine to be sprayed more precisely on the perineum. For example, when it is necessary to expand the spraying range, the medical staff only need to gently push the pull plate 44, causing the pull rod 42 to push the soft shell 41 into a tapered shape, so that the medicine can be sprayed in a more dispersed manner; when it is necessary to reduce the spraying area, only pull the pull plate 44, making the soft shell 41 flat, and the medicine can be sprayed more concentratedly. The medicine in the medicine bottle is pushed by the gas and smoothly transported from the medicine inlet cone 710 through the spray pipe 53 and the spray hose 54 to the extension column 51, and then precisely sprayed from the soft shell 41 to the place where spraying is required.

[0036] The clamping assembly 6 is composed of two groups of rotating plates 62, a mounting plate 61, a fixed ring 63, a soft ring 64, a limit disc 65 and a tension spring 66. The bottom of each group of rotating plates 62 is rotatably connected to the mounting plate 61, and the top is fixed with a fixed ring 63 with a soft ring 64. Both sides of the top of the rotating plate 62 are connected to the tension spring 66 through the limit disc 65.

[0037] Due to the initial stretched state, the tension spring 66 will generate elastic force. According to Hooke's law, the elastic force of the tension spring 66 will always make the two groups of rotating plates 62 tend to approach each other. When it is necessary to clamp the medicine bottle, the medical staff gently place the medicine bottle between the two groups of rotating plates 62, and the pulling force of the tension spring 66 will cause the rotating plates 62 to tightly clamp the medicine bottle. The presence of the soft ring 64 is of great significance. It not only increases the friction with the clamped object but also avoids damaging the surface of the object at the same time, improving the stability and safety of the clamping. It should be noted that after the use of the applicator is completed once, it must be thoroughly disinfected before the next administration work can be carried out.

[0038] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
