[0001] The utility model relates to the technical field of medical devices, in particular to a cervical medicine application device. Background Art

[0002] Chronic cervicitis is a common inflammation of the female reproductive organs. The treatment for patients with severe symptoms is generally through the use of physical therapy methods such as electric ironing, freezing, laser, and microwave. Patients need to apply anti-inflammatory and hemostatic drugs after physical therapy or after removing cervical polyps. However, due to the deep and long vagina and the cervix hanging in the middle of the vagina, medical staff cannot directly apply the medicine completely to the cervical lesions. Therefore, it is necessary to use a cervical medicine application device to apply the medicine to the patient's cervical lesions.

[0003] When using the existing cervical medication device, medical staff control the amount of medicine by the scale on the medication tube. They need to stare at the scale during injection. Manual injection has errors, making it difficult to control the amount of medicine and unable to ensure the accuracy of medication measurement.

[0004] The prior art CN215822094U discloses a clinical gynecological care cervical medication device, which controls the injection amount through a movable ring. There is no need to stare at the scale during injection. The dosage is accurately controlled and the operation is simple.

[0005] However, the protective tube and the nozzle of the above-mentioned drug applying device are not detachable, so after the drug applying is completed, the entire drug applying device needs to be discarded, which greatly increases the use cost of the drug applying device. Utility Model Content

DETAILED DESCRIPTION

[0022] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] First embodiment

[0024] See also Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall structure of the cervical medication device of the first embodiment of the present invention. Figure 2 1 is a schematic cross-sectional view of the cervical medication device according to the first embodiment of the present invention, taken along the piston 105. Figure 3 This is the first embodiment of the cervical medication device of the utility model. Figure 2 Enlarged view of point A.

[0025] The present invention provides a cervical medication application device, comprising a syringe 101, a protective tube 102, a nozzle 103, a liquid inlet tube 104, a piston 105, a push rod 106, an operating ring 107, and a sealing gasket 108. The liquid inlet tube 104 is provided with a one-way valve 109. The aforementioned solution solves the problem that the protective tube 102 and nozzle 103 of existing medication application devices are non-detachable, resulting in the need to discard the entire medication application device after medication application is completed, thereby greatly increasing the cost of using the medication application device. It is understandable that the aforementioned solution can be used in scenarios where medication is applied to a patient's cervical lesions.

[0026] In this embodiment, the medicine is transferred to the syringe 101 through the liquid inlet tube 104, and then the operating panel is pushed, so that the operating panel drives the piston 105 to move in the syringe 101 through the push rod 106, and the medicine in the syringe 101 is pushed into the nozzle 103 and sprayed out from the nozzle 103, so as to achieve uniform spraying of the medicine on the patient's cervical lesion. By providing a detachable protective tube 102 in the through hole 110 of the syringe 101, and the protective tube 102 and the nozzle 103 are integrated into one, after the medicine is applied, it is only necessary to remove the protective tube 102 from the through hole 110 of the syringe 101 and discard it, so that there is no need to discard the entire medicine application device, thereby reducing the use cost of the medicine application device.

[0027] Among them, a through hole 110 is provided on one side of the syringe 101, the protective tube 102 is detachably connected to the syringe 101 and is located in the through hole 110, the nozzle 103 and the protective tube 102 are integrated into one design, the nozzle 103 is evenly distributed with spray holes 111, and the spray holes 111 are used to evenly spray the medicine onto the patient's cervical lesions, the liquid inlet pipe 104 is connected to the syringe 101 and is located outside the syringe 101, the piston 105 is slidably connected to the syringe 101 and is located in the syringe 101, the push rod 106 is arranged on the side of the piston 105 away from the protection tube 102, the operating ring 107 is arranged on the end of the push rod 106 away from the piston 105, the through hole 110 is provided with an internal thread, and the protection tube 102 is provided with an external thread. The external thread of the protection tube 102 is threadedly connected to the internal thread of the through hole 110, so that the protection tube 102 can be installed or removed in the through hole 110, and the syringe 101, the protection tube 102 and the nozzle 103 are connected. Thus, the medicine in the syringe 101 can be transferred to the nozzle 103 through the protective tube 102 and finally sprayed out from the spray hole 111. The liquid inlet pipe 104 is connected to the syringe 101, and the liquid inlet pipe 104 is connected to the external medicine storage box, so that the medicine stored in the external medicine storage box can be transferred from the liquid inlet pipe 104 to the syringe 101. The piston 105 is made of a flexible soft material. The piston 105 can divide the internal space of the syringe 101 into two chambers. Hold the operating ring 107 and move the The operating ring 107 can drive the push rod 106 to move in the syringe 101, and further drive the piston 105 to move in the syringe 101. When the piston 105 moves toward the direction close to the protective tube 102, the air in the chamber close to the protective tube 102 is compressed, so that the medicine in the chamber close to the protective tube 102 is gradually transferred into the protective tube 102, and then transferred from the protective tube 102 to the nozzle 103, and finally evenly sprayed out from the nozzle hole 111 of the nozzle 103.

[0028] Secondly, the sealing gasket 108 is slidably connected to the protective tube 102 and is fixed in the through hole 110. The sealing gasket 108 is made of a flexible soft material. The sealing gasket 108 can seal the gap between the through hole 110 and the protective tube 102 to prevent the medicine in the syringe 101 from flowing out of the gap between the through hole 110 and the protective tube 102.

[0029] Again, the one-way valve 109 is arranged on a side of the liquid inlet tube 104 away from the syringe 101, and is used to transmit the drug into the syringe 101 in a one-way manner to avoid drug backflow and drug contamination.

[0030] When using the present invention, the protective tube 102 is gradually screwed into the through hole 110 along the thread trajectory of the external thread of the protective tube 102. When the protective tube 102 can no longer be screwed in, the protective tube 102 is limited and fixed in the through hole 110 of the syringe 101, thereby realizing the installation of the protective tube 102 in the through hole 110 of the syringe 101. At this time, the sealing gasket 108 can seal the gap between the through hole 110 and the protective tube 102 to prevent the medicine in the syringe 101 from flowing out from the gap between the through hole 110 and the protective tube 102.

[0031] After the protective tube 102 is installed in the through hole 110, the liquid inlet pipe 104 is connected to the external medicine storage box, so that the medicine stored in the external medicine storage box can be transferred to the liquid inlet pipe 104, and then transferred from the liquid inlet pipe 104 to the syringe barrel 101 in a unidirectional manner to avoid the backflow of the medicine and the contamination of the medicine.

[0032] Afterwards, the operating ring 107 is held and moved, thereby driving the push rod 106 to move in the syringe 101, and further driving the piston 105 to move in the syringe 101. When the piston 105 moves toward the direction close to the protective tube 102, the air in the chamber close to the protective tube 102 is compressed, so that the medicine in the chamber close to the protective tube 102 is gradually transferred to the nozzle 103 through the protective tube 102, and finally evenly sprayed out from the nozzle hole 111 of the nozzle 103, so as to achieve even spraying of the medicine on the patient's cervical lesion.

[0033] After the medicine is applied, the protective tube 102 is gradually unscrewed from the through hole 110 along the thread trajectory of the external thread of the protective tube 102, so that the limited fixed state of the protective tube 102 in the through hole 110 of the syringe 101 is released. When the protective tube 102 is completely unscrewed from the through hole 110, the disassembly of the protective tube 102 is completed. Thereafter, the protective tube 102 is discarded to ensure hygiene.

[0034] To summarize, the medicine is transferred into the syringe 101 through the liquid inlet tube 104, and then the operating panel is pushed, so that the operating panel drives the piston 105 to move in the syringe 101 through the push rod 106, and the medicine in the syringe 101 is pushed into the nozzle 103 and sprayed out from the nozzle 103, so as to achieve uniform spraying of the medicine on the patient's cervical lesions. By arranging the detachable protective tube 102 in the through hole 110 of the syringe 101, and the protective tube 102 and the nozzle 103 are integrated into one design, after the medicine is applied, it is only necessary to remove the protective tube 102 from the through hole 110 of the syringe 101 and discard it, so that there is no need to discard the entire medicine application device, thereby reducing the use cost of the medicine application device.

[0035] Second embodiment

[0036] See also Figures 4 and 5 , Figure 4 This is a schematic structural diagram of a drug dosage control component of a cervical medication device according to a second embodiment of the present invention. Figure 5 FIG2 is a schematic cross-sectional view of a second embodiment of a cervical medication application device according to the present invention, taken along a fixing bolt 203. Based on the first embodiment, the cervical medication application device according to the present invention further includes a medication dosage control component, which includes a movable ring 201, a movable plate 202, a fixing bolt 203, and a scale label 204.

[0037] The drug quantity control member is arranged on the outside of the syringe 101 and is used to accurately control the amount of drug sprayed by the spray head 103 onto the patient's cervical lesion.

[0038] The movable ring 201 is slidably connected to the injection barrel 101 and is sleeved on the outside of the injection barrel 101. The movable plate 202 is fixed on the outside of the push rod 106 and is located above the movable ring 201. The movable ring 201 can move outside the injection barrel 101. Since the push rod 106 can move inside the injection barrel 101, it can drive the movable plate 202 to move outside the injection barrel 101.

[0039] The fixing bolt 203 is detachably connected to the movable ring 201, abuts against the injection cylinder 101, and passes through the movable ring 201. The movable ring 201 has a threaded hole, and the fixing bolt 203 has an external thread. The fixing bolt 203 is threadedly connected to the threaded hole of the movable ring 201, so that the fixing bolt 203 can be screwed in or out of the threaded hole of the movable ring 201.

[0040] The scale label 204 is disposed between the syringe 101 and the movable ring 201 , and the syringe 101 is made of a transparent material, so that an operator can observe the amount of medicine in the syringe 101 according to the scale displayed on the scale label 204 .

[0041] When it is needed, the movable ring 201 is moved outside the syringe 101, and the amount of medicine in the syringe 101 is observed according to the scale displayed on the scale label 204. Then, the position of the movable ring 201 is adjusted according to the amount of medicine that the patient needs to apply. When the movable ring 201 moves to the specified scale position, the fixing bolt 203 is gradually screwed into the threaded hole of the movable ring 201 until the fixing bolt 203 is tightened outside the syringe 101. The movable ring 201 is limited and fixed outside the syringe 101. Then, the operating ring 107 is held by hand and moved, thereby driving the push rod 106 to move the syringe 101. The movable plate 202 and the piston 105 can be driven to move outside the syringe 101 and inside the syringe 101 respectively at the same time. The movement of the piston 105 inside the syringe 101 can transfer the medicine in the syringe 101 to the nozzle 103 through the protective tube 102, and finally be sprayed out from the nozzle 103, so as to achieve uniform spraying of medicine on the patient's cervical lesions. When the movable plate 202 contacts the movable ring 201 during the movement outside the syringe 101, the movable plate 202 can no longer be pushed, so that the amount of medicine sprayed by the nozzle 103 to the patient's cervical lesions can be accurately controlled.

[0042] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
